ROGERS, C.J., and NORCOTT, KATZ, PALMER, VERTEFEUILLE, ZARELLA and SCHALLER, Js.^[*]

PALMER, J.

At approximately 11 p.m. on September 15, 1998, the defendant, Robert Courchesne, and an acquaintance, Demetris Rodgers, were seated in the defendant's car in the parking lot of Webster Bank located on the corner of Chase and Wigwam Avenues in Waterbury, arguing over a drug debt that the defendant owed Rodgers' boyfriend. When Rodgers became upset upon learning that the defendant was unable to pay the debt, the defendant took a serrated kitchen knife that he kept in his car and repeatedly stabbed Rodgers with it in her chest and back. Rodgers, who was approximately eight and one-half months pregnant, managed to escape from the car and to run a short distance before collapsing in the street as a result of her wounds. The defendant fled the scene in his car. About fifteen minutes later, a passerby discovered Rodgers. Shortly thereafter, a police officer arrived at the scene and called for emergency medical personnel, who attempted to revive Rodgers. Rodgers then was transported to Waterbury Hospital (hospital), where she was pronounced dead. An emergency department physician performed an emergency cesarean section on Rodgers and delivered her baby, Antonia Rodgers.^[1] After Antonia was delivered, she immediately was subject to further resuscitation efforts and then placed on life support. Antonia remained on life support for forty-two days, at which time life support was removed. Within hours of removal, Antonia was pronounced dead. The cause of death was lack of oxygen to her brain, which she had suffered in utero as a result of the death of her mother.

The defendant was apprehended and charged in connection with the deaths of Rodgers and Antonia. Specifically, the defendant was charged with two counts of murder in violation of General Statutes ง 53a-54a(a)^[2] for the intentional killings of Rodgers and Antonia,^[3] one count of capital felony in violation of General Statutes (Rev. to 1997) ง 53a-54b(8)^[4] for the *15 murder of two or more persons in the course of a single transaction, and one count of capital felony in violation of ง 53a-54b(9)^[5] for the murder of a person under sixteen years of age, namely, Antonia. The trial court, Damiani, J., held a probable cause hearing in accordance with article first, ง 8, of the state constitution, as amended by article seventeen of the amendments,^[6] and General Statutes ง 54-46a(a),^[7] following which the court found probable cause to believe that the defendant had committed the crimes with which he was charged.^[8] Thereafter, the defendant waived a jury trial with respect to the guilt phase of the proceedings and elected to be tried by a three judge panel (panel), which consisted of West, Cofield and D'Addabbo, Js. The panel found the defendant guilty on all counts, and, thereafter, the trial court, D'Addabbo, J.,^[9] conducted a penalty phase hearing before a jury in accordance with General Statutes (Rev. to 1997) ง 53a-46a.^[10] At the conclusion *17 of the penalty phase hearing, the jury returned a special verdict, finding, with respect to the defendant's conviction of capital felony under ง 53a-54b(8), the existence of an aggravating factor, namely, that the defendant had committed the offense in an especially heinous, cruel or depraved manner within the meaning of ง 53a-46a(i)(4),^[11] and finding beyond a reasonable doubt that the aggravating factor outweighed any potential mitigating factor or factors. In accordance with the panel's finding of guilt and the jury's special verdict, the trial court, D'Addabbo, J., rendered judgment of guilty and sentenced the defendant to death.^[12]

On appeal to this court,^[13] the defendant challenges the panel's finding of guilt and his death sentence. With respect to the guilt phase of the proceedings, he claims, inter alia, that the trial court improperly (1) denied his motion to suppress his written confessions and other evidence linking him to the murders, (2) denied his motion to dismiss the murder and capital felony charges relating to the death of Antonia because the court improperly invoked the common-law born alive rule^[14] in concluding *18 that Antonia was a "person" for purposes of this state's murder and capital felony statutes, (3) denied his motion to dismiss after concluding that both the murder and capital felony charges relating to the death of Antonia lawfully could be predicated on the doctrine of transferred intent, and (4) permitted the state to proceed under the born alive rule and the doctrine of transferred intent in violation of his rights under the due process and ex post facto clauses of the United States constitution. In addition, the defendant claims that, even if the trial court properly recognized the existence of the born alive rule for purposes of our Penal Code, (1) the evidence was insufficient to establish beyond a reasonable doubt that Antonia was, in fact, born alive and, therefore, a "person" within the meaning of this state's murder and capital felony statutes, and (2) the state's "novel integration" of the born alive rule and the transferred intent principle embodied in ง 53a-54a(a)^[15] violated his constitutional right to fair notice that his conduct with respect to the death of Antonia fell within the murder and capital felony statutes. With respect to the penalty phase of the proceedings, the defendant claims, inter alia, that (1) the evidence was insufficient to prove beyond a reasonable doubt that he committed the murder of Rodgers in an "especially heinous, cruel or depraved manner" within the meaning of ง 53a-46a(i)(4), and (2) the jury reasonably could not have found that the aggravating factor outweighed any mitigating factor or factors.^[16]

For the reasons that follow, we reject the defendant's guilt phase claims and the penalty phase claims that we address. We nevertheless conclude that the panel applied the wrong evidentiary standard in finding that the state had established beyond a reasonable doubt that Antonia was born alive. Specifically, the panel improperly failed to consider whether, in accordance with State v. Guess, 244 Conn. 761, 764, 780, 715 A.2d 643 (1998), Antonia was brain dead at the time of her delivery due to the irreversible cessation of brain function even though her circulatory and respiratory systems were maintained by artificial means for forty-two days after her delivery. Accordingly, with respect to the murder charge arising out of the death of Antonia and both capital felony charges, all of which are predicated on the state's contention that, because Antonia was born alive, she was a person within the meaning of our Penal Code, we conclude that the defendant is entitled to a new trial at which the state will be required to prove that Antonia was not brain dead at the time she was born. If, upon retrial, the defendant is found guilty of the capital felony charge concerning the murder of Rodgers and Antonia in the course of the same transaction, the defendant also is entitled to a new penalty phase hearing. *19 Finally, we affirm the defendant's conviction for the murder of Rodgers.

I

SUPPRESSION CLAIMS

The defendant first claims that the trial court improperly denied his motion to suppress certain statements that he made to the police implicating himself in Rodgers' murder in violation of his rights under the fourth,^[17] eighth^[18] and fourteenth^[19] amendments to the United States constitution.^[20] The defendant contends that the trial court improperly rejected his claims that he was seized by the police, that the seizure exceeded the bounds of a Terry^[21] stop and that, following that stop, he did not voluntarily consent to accompany the police to the Waterbury police department for questioning. The defendant further contends, contrary to the conclusion of the trial court, that the fruits of these constitutional improprieties, including his oral and written statements in which he confessed to murdering Rodgers, must be suppressed. We disagree.

The following facts are necessary to our resolution of the defendant's suppression claims. The defendant filed a motion to suppress all oral and written statements that he had made to the police โ€” in which he allegedly confessed to murdering Rodgers โ€” on the ground that those statements had been obtained illegally. Thereafter, the trial court, O'Keefe, J., conducted a suppression hearing at which both defense counsel and the state presented evidence. The state called as witnesses Detective John Kennelly and Sergeant Gary Pelosi, both members of the criminal investigations division of the Waterbury police department. The defense witnesses included the defendant's girlfriend in 1998, Jacqueline Wilson, the defendant's neighbors, Tamara Oliver and Sydney Vega, and Paul Ariola, a detective with the Waterbury police department. No two witnesses gave the exact same account of events relating to the defendant's alleged seizure by the police.

The state's first witness, Kennelly, testified that, sometime in the early morning hours of September 16, 1998, Waterbury *20 police received information that the defendant was the last person to be seen with Rodgers before she was found mortally wounded. Acting on this information, Kennelly and Ariola set up a surveillance of the defendant's house on Sumac Street in Waterbury at approximately 8 a.m. that day. The officers, who were not in uniform, positioned their unmarked police car a short distance away from the defendant's house so that they could observe any vehicles coming down the street. At approximately 10:15 a.m., the defendant pulled up to the front of his house in a Ford Escort with a female passenger later identified as Wilson. According to Kennelly, at that point, he and Ariola immediately exited their police vehicle and approached the defendant's vehicle. After identifying himself and Ariola, Kennelly informed the defendant that they were investigating Rodgers' death and asked the defendant if he "would be kind enough" to go with them to the police station to answer some questions. The defendant replied, "sure, no problem," and exited his vehicle without being asked to do so. Kennelly characterized the defendant's demeanor as "calm, cooperative [and] rational," and further observed that the defendant did not appear to be under the influence of drugs or alcohol. The officers neither handcuffed nor arrested the defendant, and they did not tell him that he was under arrest because, according to Kennelly, there was no probable cause to arrest him at that time.

The defendant then entered Kennelly's vehicle, and Kennelly transported him to the station. Although Kennelly did not tell the defendant that he did not have to go to the station, Kennelly testified that the defendant was, in fact, free to decline to do so. After the defendant had arrived at the station, he was placed in an interview room and read his Miranda^[22] warnings from a printed card. After the defendant was advised of his rights, he signed and dated the card. The defendant then was asked whether he knew anything about Rodgers' death. The defendant immediately broke into tears and confessed that he had killed Rodgers. He then made a full oral and written confession to the murder, which included the disclosure of the location where he had disposed of the murder weapon.

Pelosi testified for the state that, in the early morning hours of September 16, 1998, Waterbury police learned from Rodgers' mother and Rodgers' boyfriend that Rodgers had been with the defendant immediately prior to her death and that Rodgers knew that the defendant was a narcotics user. Sometime between 9 and 10 a.m. that morning, Pelosi drove his unmarked police car to the defendant's Sumac Street address to participate in the surveillance. Upon his arrival there, Pelosi parked his vehicle at the other end of the street from where Kennelly and Ariola were parked and waited for the defendant. At approximately 10 a.m., Pelosi observed the defendant and Wilson pull into the defendant's driveway. At that time, Kennelly and Ariola exited their vehicle and approached the defendant's vehicle. Kennelly then spoke briefly to the defendant. According to Pelosi, Kennelly told the defendant that he wanted to speak to him at the police station about Rodgers' death and asked him if he would be willing to do so. Pelosi further testified that none of the officers was in uniform, no guns were drawn when they approached the defendant's vehicle, the defendant was not told that he was under arrest, and he was not handcuffed or otherwise restrained. Pelosi described the defendant's demeanor as *21 "very quiet, calm.... [H]e looked worried, concerned." Pelosi also stated that the defendant did not appear to be under the influence of alcohol or drugs. Kennelly then drove the defendant to the police station for questioning. At some point, Pelosi asked Wilson if she would accompany him to the station for questioning. She replied that she would and got into the front passenger seat of Pelosi's vehicle. The entire encounter, from the time the defendant and Wilson arrived on Sumac Street until they left in separate vehicles for the police station, lasted no more than five minutes.

Wilson testified at the suppression hearing for the defendant. She explained that, at approximately 10 a.m. on the day following Rodgers' murder, she and the defendant, with whom she resided, arrived on Sumac Street in her Ford Escort and noticed that many people in the neighborhood were standing in front of their houses. Before reaching his residence, the defendant pulled over to ask one of his neighbors whether she had seen Rodgers. The neighbor responded, "[N]o, cause you all murdered her." The defendant then proceeded to drive down the street toward his residence. When he arrived there, a police car appeared. According to Wilson, the defendant immediately attempted to turn around and to leave, but the police told him "to stop," and then "blocked him in." Wilson further testified that the police "made" her and the defendant get out of the vehicle. When asked if she had any choice in the matter, she replied, "I didn't know. I just did what they told me." Wilson also explained, however, that, after exiting the vehicle, she went to the police station voluntarily.

Oliver testified that she was standing outside her house on Sumac Street in the morning hours of September 16, 1998, when she saw the defendant and Wilson drive up the street. The defendant pulled his vehicle over next to Oliver, and Wilson asked Oliver if she had seen Rodgers. Oliver responded that she had not. The defendant then continued driving toward his house, but a police car was parked nearby. When the defendant saw the police car, he tried to back up and to leave. At that point, however, the police car pulled up beside the defendant's car, causing him to stop. Oliver could not hear any conversation but observed the defendant exit his vehicle and subsequently enter the officer's car. Shortly thereafter, Wilson also got out of the vehicle and entered another police car that also had arrived at the scene. Both police cars then departed.

Ariola testified that the only car participating in the surveillance was the car that he and Kennelly were driving and that the officers had parked their car about three houses beyond the defendant's house on the opposite side of the street. After the defendant arrived with Wilson in Wilson's Ford Escort, the defendant pulled in front of his residence, waited "[a] few seconds" and then started to drive away. Before the defendant could drive away, however, Ariola moved his car into the middle of the street and stopped so close to the defendant's car that the defendant could not get by him. The defendant made no further attempts to drive away. Ariola testified that, if the defendant had asked the officers to move, there would have been "no reason" to prevent him from backing up. The officers then exited their car and approached the defendant's vehicle; Kennelly approached along the driver's side and Ariola approached along the passenger's side. After the officers identified themselves, Kennelly told the defendant that he wanted the defendant to accompany him to the police station to talk about Rodgers. Neither officer had his gun drawn. Ariola further testified that there was no probable cause at that time to *22 arrest the defendant and that the officers merely had wanted to question him because they had information that he was with Rodgers shortly before her death. The officers asked the defendant and Wilson to exit their vehicle, and, shortly thereafter, Pelosi arrived at the scene. The officers then called a tow truck for the defendant's car. Ariola testified that "everybody," including the defendant, was a suspect at the time, and the officers' intention was to question, not to arrest, the defendant. After Kennelly and Pelosi left the scene in separate cars with the defendant and Wilson, respectively, Ariola stayed behind to secure the area and to guard the defendant's vehicle until it could be towed away.

The final defense witness was Vega, the defendant's next-door neighbor. Vega testified that, on the morning of the surveillance, he was standing in his front yard and saw four "marked" police cars block the defendant's vehicle as the defendant approached his home. According to Vega, the police officers opened the defendant's car door, "pointed a gun at [the defendant]," and "pulled him out" of the car. Immediately thereafter, the defendant, who was not handcuffed, was placed in one of the police vehicles. Vega stated that he was approximately 600 feet from the scene when he observed the events that formed the basis of his testimony.

Following this testimony, the trial court, O'Keefe, J., denied the defendant's motion to suppress. In an oral ruling, the court found that the "confrontation or ... meeting" between the police and the defendant on the morning of September 16, 1998, did not have the "indicia of an arrest." In support of this conclusion, the court observed that the officers did not run up to the defendant or draw their weapons when they approached him. The court stated that Vega's testimony that the officers had drawn their weapons was not credible, noting that, of all the witnesses, Vega was the only one to testify that the police were brandishing guns when they approached the defendant. The court also found that, although the officers "did stop [the defendant's] car," their actions were reasonable under the circumstances because it might not have been possible for the officers otherwise to have captured the defendant's attention to alert him to the fact that they wanted to speak with him. The court further found that the confrontation between the defendant and the police was not a seizure for constitutional purposes, and, even if it was, it was based on a "reasonable, articulable suspicion" that the defendant was involved in Rodgers' death because her murder had occurred only a few hours earlier and the defendant had been identified as the last person to be seen with Rodgers while she was still alive. The court made no other specific findings with respect to the issue of whether the police had exceeded the permissible limits of a Terry stop. The court did note, however, that police officers are paid to speak with people in furtherance of criminal investigations and, therefore, that the officers in the present case had every right to try to speak with the defendant. Finally, the court found that the defendant had gone to the police station voluntarily. In support of this conclusion, the court observed that the defendant may have done so out of feelings of remorse or shame for what he had done because, as soon as he arrived at the station, he immediately began to cry and confessed to stabbing Rodgers. The court concluded, on the basis of the defendant's behavior, that he did not "sound like somebody who is really resistant to the efforts of the police to talk to him." Although the court stated that it would expand on its oral ruling in a *23 written memorandum of decision to follow, no such memorandum ever was issued.^[23]

"Our standard of review of a trial court's findings and conclusions in connection with a motion to suppress is well defined. A finding of fact will not be disturbed unless it is clearly erroneous in view of the evidence and pleadings in the whole record.... [When] the legal conclusions of the court are challenged, we must determine whether they are legally and logically correct and whether they find support in the facts set out in the memorandum of decision.... We undertake a more probing factual review when a constitutional question hangs in the balance.... In the present case, in which we are required to determine whether the defendant was seized by the police, we are presented with a mixed question of law and fact that requires our independent review." (Citations omitted; internal quotation marks omitted.) State v. Burroughs, 288 Conn. 836, 843-44, 955 A.2d 43 (2008). "When considering the validity of a ... stop, our threshold inquiry is twofold.... First, we must determine at what point, if any ... the encounter between [the police officer] and the defendant constitute[d] an investigatory stop or seizure.... Next, [i]f we conclude that there was such a seizure, we must then determine whether [the police officers] possessed a reasonable and articulable suspicion at the time the seizure occurred." (Citations omitted; internal quotation marks omitted.) State v. Santos, 267 Conn. 495, 503, 838 A.2d 981 (2004).

"Under the fourth amendment to the United States [c]onstitution ... a police officer is permitted in appropriate circumstances and in an appropriate manner to detain an individual for investigative purposes if the officer believes, based on a reasonable and articulable suspicion that the individual is engaged in criminal activity, even if there is no probable cause to make an arrest. Alabama v. White, 496 U.S. 325, 330-31, 110 S.Ct. 2412, 110 L.Ed.2d 301 (1990); Terry v. Ohio, [392 U.S. 1, 22, 88 S.Ct. 1868, 20 L.Ed.2d 889 (1968)]; State v. Mitchell, 204 Conn. 187, 194-95, 527 A.2d 1168, cert. denied, 484 U.S. 927, 108 S.Ct. 293, 98 L.Ed.2d 252 (1987). Reasonable and articulable suspicion is an objective standard that focuses not on the actual state of mind of the police officer, but on whether a reasonable person, having the information available to and known by the police, would have had that level of suspicion....

"[I]n justifying [a] particular intrusion the police officer must be able to point to specific and articulable facts which, taken together with the rational inferences from those facts, reasonably warrant that intrusion. Terry v. Ohio, supra, 392 U.S. [at] 21 [88 S.Ct. 1868] .... In determining whether a detention is justified in a given case, a court must consider [whether], relying on the whole picture, the detaining officers had a particularized and objective basis for suspecting the particular person stopped of criminal activity. When reviewing the legality of a stop, a court must examine the specific information *24 available to the police officer at the time of the initial intrusion and any rational inferences to be derived therefrom.... A recognized function of a constitutionally permissible stop is to maintain the status quo for a brief period of time to enable the police to investigate a suspected crime.... State v. Lipscomb, 258 Conn. 68, 75-76, 779 A.2d 88 (2001); see also Adams v. Williams, 407 U.S. 143, 146, 92 S.Ct. 1921, 32 L.Ed.2d 612 (1972) ([a] brief stop of a suspicious individual, in order to determine his identity or to maintain the status quo momentarily while obtaining more information, may be most reasonable in light of the facts known to the officer at the time).

"In addition, [e]ffective crime prevention and detection ... [underlie] the recognition that a police officer may in appropriate circumstances and in an appropriate manner approach a person for purposes of investigating possibly criminal behavior even though there is no probable cause to make an arrest. Terry v. Ohio, supra, 392 U.S. [at] 22 [88 S.Ct. 1868]. Therefore, [a]n investigative stop can be appropriate even [when] the police have not observed a violation because a reasonable and articulable suspicion can arise from conduct that alone is not criminal.... In evaluating the validity of such a stop, courts must consider whether, in light of the totality of the circumstances, the police officer had a particularized and objective basis for suspecting the particular person stopped of criminal activity." (Internal quotation marks omitted.) State v. Colon, 272 Conn. 106, 149-50, 864 A.2d 666 (2004), cert. denied, 546 U.S. 848, 126 S.Ct. 102, 163 L.Ed.2d 116 (2005).

This court also has recognized that "[t]he test enunciated by the United States Supreme Court [regarding] whether an investigative stop passes constitutional muster balances the nature of the intrusion [on] personal security against the importance of the governmental interest inducing the intrusion. See United States v. Hensley, [469 U.S. 221, 228, 105 S.Ct. 675, 83 L.Ed.2d 604 (1985)]. A strong law enforcement interest has been particularly recognized in the context of felonies or violent crimes, because `it is in the public interest that the crime be solved and the suspect detained as promptly as possible.' Id., [at] 229 [105 S.Ct. 675]. Furthermore, when the situation in which a suspect has been detained has afforded him a lesser expectation of privacy ... fourth amendment protections have been deemed to be correspondingly less stringent." (Citations omitted.) State v. Mitchell, supra, 204 Conn. at 196, 527 A.2d 1168. Because the intrusion resulting from an investigative stop is minimal, the reasonable suspicion standard is not onerous.

"The determination of whether a reasonable and articulable suspicion exists rests on a two part analysis: (1) whether the underlying factual findings of the trial court are clearly erroneous; and (2) whether the conclusion that those facts gave rise to such a suspicion is legally correct." (Internal quotation marks omitted.) State v. Santos, supra, 267 Conn. at 504-505, 838 A.2d 981.

The state does not directly address the propriety of the court's finding that the encounter between the defendant and the police officers in the street in front of the defendant's house did not constitute a seizure. The state contends, however, that, even if we assume, arguendo, that the officers' conduct did constitute a seizure, the court properly concluded that the seizure was a lawful Terry stop. In particular, the state contends that the stop satisfied the requirements of Terry because it was based on the officers' reasonable, articulable suspicion that the defendant was involved in Rodgers' murder and because the stop was limited in scope and duration, *25 lasting no longer than necessary to effectuate its purpose of inquiring whether the defendant would be willing to answer some questions about Rodgers and the circumstances surrounding her death. The defendant does not challenge the court's finding that the facts in existence at the time of the stop gave rise to a reasonable, articulable suspicion on the part of the police officers to justify a Terry stop.^[24] The defendant claims, rather, that the officers' detention of him "was marked by such intrusiveness, displays of force and coercion that it exceeded the bounds of a stop permitted by Terry" and, therefore, constituted a de facto arrest, which required probable cause. In support of his claim that the officers used undue force in detaining him, the defendant asserts that, in addition to blocking his vehicle, two or three armed officers surrounded him and ordered him out of the vehicle, behaved in a "blunt and forceful manner" toward him, and conveyed such urgency when they sought to have the defendant accompany them to the station that he was forced to abandon his vehicle in the middle of the road.

In response, the state maintains that the only aspect of the stop that even arguably could be characterized as involving a degree of compulsion or force was the officers' use of their unmarked police vehicles to prevent the defendant from driving away. The state contends, however, that, when viewed in light of the totality of circumstances, the officers' blocking the defendant's vehicle so that he could not leave before the officers were able to speak to him was a reasonable means of maintaining the status quo so that the officers could complete the purpose of the investigatory stop. In other words, the state asserts that the challenged police action did not transform the stop into an arrest.

For purposes of this appeal, we assume, arguendo, that the police seized or detained the defendant when they approached him and confronted him with the request that he accompany them to the station. We conclude, however, that the trial court properly determined that the seizure of the defendant by the police constituted a lawful Terry stop.

"A Terry stop that is justified at its inception can become constitutionally infirm if it lasts longer or becomes more intrusive than necessary to complete the investigation for which that stop was made.... Like the determination of initial justification, this inquiry is fact-bound." (Citations omitted; internal quotation marks omitted.) State v. Mitchell, supra, 204 Conn. at 197, 527 A.2d 1168. Whether *26 the detention of a suspect exceeds the scope of a permissive investigative stop, however, is a question of law. See, e.g., State v. Nash, 278 Conn. 620, 641, 899 A.2d 1 (2006).

"One function of a constitutionally permissible Terry stop is to maintain the status quo for a brief period of time to enable the police to investigate a suspected crime. A police officer who has proper grounds for stopping a suspect has constitutional permission to immobilize the suspect briefly in order to check a description or an identification, [as] long as his conduct is strictly tied to and justified by the circumstances [that] rendered its initiation permissible.... Determination of the means that are reasonably necessary to maintain the status quo necessarily depends on a fact-bound examination of the particular circumstances of the particular governmental intrusion on the personal security of a suspect." (Citations omitted; internal quotation marks omitted.) State v. Braxton, 196 Conn. 685, 689, 495 A.2d 273 (1985). "A police officer who has articulable grounds to believe that a crime has been committed and to detain someone who may be implicated in that crime must be permitted to make reasonable use of the resources at his disposal at the site of the investigatory stop." Id., at 690, 495 A.2d 273.

The defendant claims that two or three armed officers surrounded him, ordered him out of his vehicle and used undue force in detaining him. The defendant's characterization of what occurred, however, is not fully consistent with the trial court's findings concerning the officers' conduct. As we previously have indicated, although the court made only limited factual findings with respect to the encounter between the police and the defendant, it determined that the confrontation had none of the indicia of an arrest because the officers "didn't have any guns out, [and] they didn't run up to [the defendant]." The court further found that, although the officers "did stop [the defendant's] car" by pulling in front of it, that action was the only way for them to get the defendant's attention so that they could talk to him. At no time did the police ever handcuff the defendant or otherwise inform him that he was not free to leave. Moreover, Kennelly testified that he had asked the defendant if he would be willing to accompany him to the station for questioning. Although one witness, namely, Vega, testified that the officers actually had drawn their guns, the court did not credit his testimony and was not required to do so. None of the other witnesses, including Wilson, the defendant's girlfriend, described any conduct on the part of the officers that could be construed as unduly coercive, threatening or oppressive. Although it is true that Kennelly and Ariola approached the defendant's vehicle from both sides, this was not unreasonable in view of the fact that the defendant was accompanied by Wilson, who was sitting in the front passenger seat. Because the suppression hearing testimony fully supports the trial court's factual findings and its conclusion concerning the propriety of the Terry stop, we see no reason to disturb those findings and conclusions.

The defendant nevertheless claims that the officers, by virtue of their actions, exceeded the scope of a permissible investigative stop, as a matter of law, when they approached and communicated with him. "When engaging in a fourth amendment reasonableness inquiry, we ask, would the facts available to the officer at the moment of the seizure or the search warrant a [person] reasonable caution in the belief that the action taken was appropriate?... [T]o satisfy the reasonableness standard, officers conducting stops on *27 less than probable cause must employ the least intrusive means reasonably available to effect their legitimate investigative purposes.... At the same time, however, the law recognizes the important need to allow authorities to graduate their responses to the demands of any particular situation." (Citations omitted; internal quotation marks omitted.) State v. Nash, supra, 278 Conn. at 641-42, 899 A.2d 1.

Connecticut courts have found the patdown of a suspect, the search of a suspect's vehicle and the approach of officers with their guns drawn to be within the permissible bounds of a Terry stop depending on the circumstances. Thus, in State v. Wilkins, 240 Conn. 489, 692 A.2d 1233 (1997), for example, this court held that an investigatory detention was lawful when a uniformed officer, following a traffic stop of a vehicle during which its two occupants engaged in furtive conduct, approached the vehicle with his gun drawn, ordered the occupants out and, thereafter, conducted a patdown search of the occupants and a limited search of their vehicle for weapons. Id., at 493-94, 501-504, 692 A.2d 1233; see also State v. Casey, 45 Conn.App. 32, 41-44, 692 A.2d 1312 (actions of police officers did not exceed permissible limits of investigative detention under Terry, even though police officers removed defendant and other suspects from vehicle at gunpoint, searched vehicle, defendant and other suspects twice, handcuffed defendant and other suspects and placed them in back of police cruisers for one hour before making identifications necessary for probable cause to arrest, when police had information that defendant and other occupants of vehicle may have been involved in shooting and officers' actions accounted for safety of public and themselves), cert. denied, 241 Conn. 924, 697 A.2d 360 (1997); State v. Holloman, 20 Conn.App. 521, 526, 568 A.2d 1052 (permissible in course of Terry stop for officers to order occupants out of car at gunpoint when report indicated occupants were involved in local armed robbery in which handgun was stolen), cert. denied, 214 Conn. 805, 573 A.2d 317 (1990); State v. Wylie, 10 Conn.App. 683, 687-88, 525 A.2d 528 (mere fact that officer ordered defendant to stop with officer's gun drawn does not automatically convert Terry stop into arrest), cert. denied, 204 Conn. 807, 528 A.2d 1154 (1987).

Guided by the general principles articulated in the foregoing cases and the policy considerations underlying Terry, we reject the defendant's claim that the officers engaged in conduct that was more intrusive or more coercive than necessary to effectuate a legitimate Terry stop. In view of the fact that the officers were investigating a murder that had occurred in the area only a few hours earlier and the fact that the defendant was the last person seen with the victim, the officers' conduct in detaining him briefly was not unreasonable. The only police conduct that fairly may be characterized as coercive was the action undertaken by the officers in blocking the defendant's vehicle to ensure that he would not leave the area before they could speak to him. In light of the defendant's attempt to leave almost immediately after he pulled up to his house, we agree with the trial court that blocking the defendant's vehicle likely was the most efficacious way to maintain the status quo so that the police could gain the defendant's attention. Other courts agree that such action ordinarily is permissible to maintain the status quo when the subject of the investigatory stop is in a vehicle and, therefore, has the capacity to flee from the scene unless physically blocked from doing so. See, e.g., United States v. Tuley, 161 F.3d 513, 515 (8th Cir.1998) ("[b]locking a vehicle so its occupant is unable to leave during the course *28 of an investigatory stop is reasonable to maintain the status quo while completing the purpose of the stop"); Commonwealth v. Hall, 50 Mass.App. 208, 210, 736 N.E.2d 425 ("[b]locking generally will be reasonable [for purposes of a Terry stop] when the suspect is in a vehicle because of the chance that the suspect may flee upon the approach of police with resulting danger to the public as well as to the officers involved" [internal quotation marks omitted]), review denied, 432 Mass. 1111, 739 N.E.2d 701 (2000).

Furthermore, as we previously indicated, the officers, who were driving an unmarked car and were not in uniform, approached the defendant's vehicle without drawing their guns and merely requested that the defendant accompany them to the police station for questioning about the murder. Thus, other than Vega, whose testimony the trial court expressly discredited, no witness described the officers as having engaged in any conduct that reasonably may be deemed to be unduly intimidating or coercive under the circumstances with which the police officers were confronted when they stopped the defendant.

The defendant cites several cases for the proposition that the officers used a level of force and coercion that exceeded the limits of a lawful Terry stop. The officers in those cases, however, used far more coercive techniques than those that were employed by the officers in the present case. See Park v. Shiflett, 250 F.3d 843, 851-52 (4th Cir.2001) (defendant's liberty was curtailed to degree associated with formal arrest because he would not have felt free to leave after being thrown against wall, kicked, handcuffed and locked in patrol car); United States v. Robinson, 30 F.3d 774, 785 (7th Cir.1994) (stop escalated into arrest when defendant was placed in handcuffs and read his Miranda rights); Oliveira v. Mayer, 23 F.3d 642, 645-46 (2d Cir.1994) (court concluded that police had gone beyond investigatory stop of suspects and had arrested them on basis of facts that suspects had been "boxed-in by six police vehicles and outnumbered two-to-one by officers with guns drawn or at the ready," ordered from vehicle, harshly treated, kept in handcuffs for duration of detention, placed in separate police cruisers and questioned with or without Miranda warnings, and extensively searched), cert. denied, 513 U.S. 1076, 115 S.Ct. 721, 130 L.Ed.2d 627 (1995); United States v. Anderson, 981 F.2d 1560, 1566 (10th Cir.1992) (blocking of defendant's egress by two agents in separate cars and approach by agent with drawn gun constituted arrest that required probable cause because suspect was not free to leave); United States v. Codd, 956 F.2d 1109, 1110-11 (11th Cir.1992) (detention went beyond bounds of Terry stop when officer asked suspect to stop and identify herself, placed her in handcuffs, took her to police station, handcuffed her to chair and searched her purse); United States v. Ricardo D., 912 F.2d 337, 340 (9th Cir.1990) (investigatory stop transformed into arrest when officers took hold of and isolated unarmed, compliant juvenile by shining high beams of police car in his face, patting him down, gripping his arm, telling him not to run anymore and directing him to back of one of two patrol cars); State v. Edwards, 214 Conn. 57, 70-73, 570 A.2d 193 (1990) (detention in course of Terry stop exceeded permissible limits when officers placed defendant in handcuffs and transported him to police head-quarters to be held for investigative purposes for indefinite period of time). In fact, none of the elements associated with the impermissible Terry stops in the foregoing cases is present in this case: the officers who confronted the defendant did not draw their guns, did not place the defendant in *29 handcuffs, did not seize any items in his possession or control, did not tell him or indicate to him that he could not leave, did not lock him in a patrol car and did not use any other type of physical force against him that might have been considered excessive under the circumstances. The defendant therefore cannot prevail on his claim that the conduct of the officers exceeded the permissible bounds of a Terry stop as a matter of law.

The defendant also claims that he did not agree voluntarily to go to the police station to be questioned about the murder. He contends that his purported consent to speak to the police was the fruit of his illegal seizure and that, even if it was not, his agreement merely reflected his submission to lawful authority. We reject the defendant's contentions.

We first address the defendant's claim that his consent was invalid because it was the fruit of an illegal seizure. "Courts have frequently held that a purportedly voluntary consent given after an illegal arrest or search is nonetheless a tainted fruit when that consent was given very soon after the illegal police action. See, e.g., United States v. Recalde, 761 F.2d 1448, 1459 (10th Cir.1985) (consent given promptly after illegal arrest invalid); United States v. Gooding, 695 F.2d 78, 84 (4th Cir.1982) (consent occurring `within the same brief continuous encounter' as illegal seizure invalid); State v. Raheem, 464 So.2d 293, 297-98 (La.1985) (consent given within forty minutes of arrest invalid). These decisions imply that a consent given in very close temporal proximity to the official illegality is often a mere submission or resignation to police authority and not necessarily an act of free will." State v. Cates, 202 Conn. 615, 621-22, 522 A.2d 788 (1987). In light of our determination that the defendant's detention was lawful under Terry, however, the defendant cannot establish that his answers to questions posed to him by the police at the station constituted the fruit of an illegal seizure.

The defendant next asserts that, even if he was the subject of a lawful investigatory stop, he did not consent voluntarily to go to the police station for questioning because, under the totality of the circumstances, his agreement to do so was the product of police coercion. The defendant also contends that the evidence demonstrates that he merely was submitting to lawful authority. We reject these claims.

It is well established that "[t]he question [of] whether consent ... has ... been freely and voluntarily given, or was the product of coercion, express or implied, is a question of fact to be determined from the totality of all the circumstances... and, ultimately, requires a determination regarding the putative consenter's state of mind." (Citation omitted; internal quotation marks omitted.) State v. Reynolds, 264 Conn. 1, 44, 836 A.2d 224 (2003), cert. denied, 541 U.S. 908, 124 S.Ct. 1614, 158 L.Ed.2d 254 (2004). "The state must affirmatively establish that the consent was voluntary; mere acquiescence to a claim of lawful authority is not enough to meet the state's burden.... As a question of fact, it is normally to be decided by the trial court [on] the evidence before that court together with the reasonable inferences to be drawn from that evidence.... We may reverse [the trial court's factual] findings on appeal only if they are clearly erroneous." (Internal quotation marks omitted.) State v. Azukas, 278 Conn. 267, 275, 897 A.2d 554 (2006). "We are particularly mindful that all of these factual findings revolve principally around the credibility of the witnesses who appeared before the trial court, the evaluation of which is left to the trial court's sound discretion because *30 of its function to weigh and interpret the evidence before it." Id., at 277, 897 A.2d 554.

This court recently considered the issue of voluntary consent in State v. Azukas, supra, 278 Conn. at 267, 897 A.2d 554. In Azukas, several officers were granted entry into a home in which the defendant, Anthony Azukas, a suspect in a murder, was staying with his girlfriend and their infant child.^[25] Id., at 271, 897 A.2d 554. The police located Azukas in an upstairs bedroom and told him that they would like to speak to him about a murder that they were investigating. Id., at 273-74, 897 A.2d 554. Azukas agreed to accompany the officers to the police station, where he confessed to the murder. Id., at 271-72, 897 A.2d 554. On appeal, Azukas claimed that the trial court improperly had denied his motion to suppress his inculpatory statements because, inter alia, his consent to accompany the police to the station had not been voluntary. See id., at 272, 284-85, 897 A.2d 554. In rejecting the claim, we observed that the trial court specifically had credited testimony, adduced by the state, that Azukas willingly had agreed to go to with the officers to the station and that he had not been placed under arrest, handcuffed or otherwise restrained in any way. Id., at 284, 897 A.2d 554. Furthermore, the evidence adduced by the state indicated that the officers had not engaged in any coercive conduct toward Azukas and that they also did not argue with him or harass him in any way. Id., at 284-85, 897 A.2d 554. We concluded that the suppression hearing testimony supported the trial court's conclusion that Azukas had consented to accompany the officers voluntarily. Id.

Similarly, in State v. Colon, supra, 272 Conn. at 107, 864 A.2d 666, we observed that the defendant, Ivo Colon, voluntarily had accompanied the police to the station, where he confessed to the fatal beating of a two year old child.^[26] Id., at 133, 140-41, 864 A.2d 666. We explained that the trial court had found that, after the police confronted Colon in the hallway of his mother's apartment; see id., at 131, 137, 864 A.2d 666; they briefly detained him under Terry and asked him if he would go to the station with them to discuss the child's injuries. Id., at 151-52 n. 15, 864 A.2d 666. When Colon nodded affirmatively, he was transported to the station by the police. Id. We further noted that the trial court had found that "[t]here were no guns drawn, or any evidence of threats, or physical force. The evidence that the court finds credible is that [Colon] was not handcuffed. He was placed in an unmarked police cruiser, without a cage, and taken to police headquarters. [Colon's] demeanor was calm and [he was] under control. Although the police did not tell [Colon that] he could refuse to go to the police station, he did not object or request to go to the... station at another time." (Internal quotation marks omitted.) Id. We thus characterized the evidence as indicating that Colon had consented voluntarily to go to the police station for questioning. See id.

Other courts also have concluded that a defendant's consent to accompany the police *31 to the station was voluntary when the defendant appeared willing to do so and there was no evidence of coercion. See, e.g., United States v. Mendenhall, 446 U.S. 544, 557-58, 100 S.Ct. 1870, 64 L.Ed.2d 497 (1980) (respondent voluntarily agreed to accompany federal agents to airport office after being approached on concourse and asked by agents if she would do so and there was no threat or show of force); United States v. Kimball, 25 F.3d 1, 8 (1st Cir.1994) (defendant voluntarily consented to accompany officers to police station because, even though he was not told that he was free to leave or free to refuse further questioning, he expressly agreed to go to station when asked several times, never indicated any unwillingness to do so, and officers did not handcuff, physically restrain, threaten to arrest, coerce or otherwise intimidate defendant); State v. Navarro, 201 Ariz. 292, 296-97, 34 P.3d 971 (2001) (defendant voluntarily consented to accompany officer to police station for questioning after defendant arrived voluntarily at scene of investigation, plainclothes officers did not surround him on public street, handcuffs were removed almost immediately after being placed on him, and defendant verbally agreed to accompany officers to station upon being asked to do so); State v. Bragan, 920 S.W.2d 227, 243 (Tenn.Crim.App.1995) (defendant voluntarily agreed to accompany police officers to station, there having been no threats, no show of force and no physical compulsion to accompany officers, even though speaking officer's tone of voice indicated that trip to station was mandatory). But cf. United States v. Gonzalez, 763 F.2d 1127, 1128, 1132 (10th Cir.1985) (defendant did not voluntarily consent to accompany police officer to station when officer withheld defendant's driver's license, car registration and title and defendant therefore had no reasonable choice other than to accompany officer no matter how polite officer was in phrasing request).

Turning to the present case, we conclude that the trial court properly found that the defendant voluntarily had agreed to go to the police station for questioning. There is no evidence that the officers forced or otherwise pressured the defendant to accompany them to the station. In fact, the testimony indicated that the defendant was cooperative with the police, who were not in uniform and did not display their weapons, and that he got out of his vehicle without being asked to do so. The defendant never was restrained, his demeanor was described as calm, and he did not appear to be under the influence of alcohol or drugs. Finally, and perhaps most importantly, the evidence that the state adduced demonstrated that the police had asked the defendant if he would be willing to accompany them to the station; at no time was the defendant told that he was obligated to go to the station or that he otherwise was required to speak to the police. Although it may be true that most people would view such an approach by the police with concern or apprehension, we never have held that a Terry stop is so inherently coercive as to compel the conclusion that the suspect's agreement to speak to the police could not have been voluntary. On the contrary, the test is fact specific, so that, ultimately, the determination of whether the consent was voluntary rests on a careful consideration of the totality of the relevant circumstances. The record supports the trial court's conclusion that the defendant voluntarily agreed to accompany the police to the station upon being requested to do so.

The defendant nevertheless has identified twenty-five "circumstances," *32 or reasons,^[27] that purportedly demonstrate why his consent was not voluntary. Several of these reasons relate to the fact that the officers did not inform the defendant that he was not required to comply with their request that he accompany them to the police station or that they did not specifically ask him whether his consent was voluntary. Indeed, Kennelly acknowledged that he did not inform the defendant that he did not have to go to the station. It was altogether reasonable, however, for the trial court to have concluded that this fact, standing alone, was insufficient to render the defendant's consent involuntary. Indeed, as the United States Supreme Court has stated, "we cannot accept the position ... that proof of knowledge of the right to refuse consent is a necessary prerequisite to demonstrating a `voluntary' consent. Rather, it is only by analyzing all the circumstances of an individual consent that it can be ascertained whether in fact it was voluntary or coerced. It is this careful sifting of the unique facts and circumstances of each case that is evidenced in our prior decisions...." Schneckloth v. Bustamonte, 412 U.S. 218, 232-33, 93 S.Ct. 2041, 36 L.Ed.2d 854 (1973); see also United States v. Thompson, 524 F.3d 1126, 1134 (10th Cir. 2008) ("knowledge of the right to refuse consent is not a necessary prerequsite" to establishing that consent was voluntary [internal quotation marks omitted]); United States v. Lattimore, 87 F.3d 647, 651 *33 (4th Cir.1996) (same); Symes v. United States, 633 A.2d 51, 53-54 (D.C.1993) (same). Under the circumstances of the present case, the mere fact that the police did not inform the defendant of his right to refuse to accompany them to the station does not invalidate the court's finding that his agreement to do so was the product of his voluntary consent and not police coercion.

The defendant also claims that his consent was involuntary because the officers (1) blocked him from leaving the scene, (2) were armed, (3) approached on both sides of his vehicle, (4) did not allow him to move his vehicle from the middle to the side of the road, (5) sought his consent immediately after he was seized, (6) were blunt in their manner, and (7) had him ride to the police station in the backseat of their vehicle instead of having him drive his own vehicle. We disagree with the defendant's contention that these facts required a finding that his consent had not been obtained voluntarily. Although these facts are relevant to the determination of whether the defendant's consent was voluntary, they are not necessarily dispositive of that issue, and the trial court was not bound to treat them as such. Indeed, in light of the other facts that demonstrate the defendant's willingness to accompany the police, the trial court reasonably concluded that the defendant had agreed to do so voluntarily.^[28] We therefore reject the defendant's contention that the trial court improperly denied his motion to suppress his inculpatory statements and the fruits thereof.

II

BORN ALIVE RULE

The defendant next claims that, in denying his motion to dismiss the murder count and the two capital felony counts predicated on Antonia's death, the trial court, Damiani, J., improperly invoked the born alive rule in connection with its determination that Antonia was a "person" within the meaning of this state's murder and capital felony statutes. The defendant contends that there is no precedent in this state pursuant to which a defendant may be held liable for a homicide that is founded on an injury inflicted on a fetus and, even if such authority existed, the rule is obsolete and should not be followed. The defendant further claims that the born alive rule is inconsistent with, and thus abrogated by, our Penal Code, because, under the Penal Code, "criminal liability [is premised] on attendant circumstances that must exist at the time the [crime was committed]." The defendant maintains that, in light of this principle, he could not have murdered Antonia within the meaning of the Penal Code because of the lack of a temporal nexus between his criminal conduct and her status as a person. In a related vein, the defendant, relying on his contention concerning the inapplicability of the born alive rule, further maintains that his intent to kill Rodgers could not be transferred to Antonia under the transferred intent provisions of ง 53a-54a(a) because he engaged in the conduct resulting in Antonia's death when Antonia was *34 not a person. Finally, the defendant claims that the trial court's "novel" application of the "twin legal fictions" of the born alive rule and the doctrine of transferred intent, as a basis for concluding that the state could prosecute him for murder and capital felony, violated his constitutional right to fair warning under the due process clause of the fourteenth amendment and constituted a violation of the ex post facto clause of article one, ง 10, of the United States constitution.^[29]

The following facts and procedural history are relevant to our resolution of these claims. On February 11, 1999, the trial court, Damiani, J., conducted a probable cause hearing on the two counts of murder and the two counts of capital felony with which the defendant had been charged. Because three of the counts require proof by the state that Antonia was born alive, namely, the counts alleging the murder of Antonia, the murder of a person under the age of sixteen (Antonia) and the murder of two or more persons (Rodgers and Antonia) in a single transaction, the state adduced testimony from Richard S. Palmer, the emergency department physician who delivered Antonia via cesarean section.^[30] Due to the circumstances, Palmer had only an extremely limited opportunity to observe Antonia, but he did observe that Antonia was not breathing and was not making any sounds at the time of delivery. He also made no attempt to resuscitate Antonia; instead, immediately after delivering Antonia, Palmer transferred her to a physician's assistant, who then rushed her to the pediatric intensive care unit. Approximately one-half hour after the delivery, Palmer went to that unit and treated a laceration that Antonia had suffered during the cesarean section. At that time, Antonia's vital signs, that is, her heart rate and respiration, had been stabilized, and she had been placed on a ventilator. Palmer thereafter completed the appropriate paperwork for the issuance of Antonia's birth certificate, which signified that she had been born alive. Over the next several weeks, Palmer often checked on Antonia, who continued to exhibit stable vital signs until, six weeks later, when she was removed from the ventilator and subsequently pronounced dead.

On the same day as the probable cause hearing, the defendant filed a motion to dismiss the capital felony charges and the charge relating to Antonia's murder, and made a request for a finding of no probable cause. In the motion to dismiss, the defendant asserted that these charges were legally deficient because, inter alia, (1) Antonia was a fetus when the defendant inflicted the injuries that resulted in her death, and, as a matter of law, a fetus is not a person under this state's murder *35 and capital felony statutes, (2) the evidence was insufficient to establish the requisite "concurrence between the [necessary] mens rea and the actus reus of the charged offenses," and (3) prosecuting the defendant under the born alive rule violates his right to notice under the relevant due process and ex post facto provisions of the federal constitution.

On May 19, 1999, the trial court denied the defendant's motion to dismiss and request for a finding of no probable cause. State v. Courchesne, 46 Conn.Supp. 63, 757 A.2d 699 (1999). In its memorandum of decision, the trial court characterized the fundamental question presented as "whether the defendant can be tried for murder and capital felony for the killing of an infant who succumbs forty-two days following a [cesarean] birth necessitated by the fatal stabbing of her pregnant mother...." Id., at 64, 757 A.2d 699. The court observed that, to establish that the defendant had committed the crimes of murder and capital felony arising out of the death of Antonia, the state was required to prove that Antonia was a "person" within the meaning of the murder and capital felony statutes. See id., at 65, 757 A.2d 699. Because General Statutes ง 53a-3(1) defines "person" simply as a "human being," a term that itself is not defined in our statutes, the trial court turned to the Model Penal Code and the New York Penal Law for guidance. Id., at 66-67, 757 A.2d 699. The court observed that, under the New York Penal Law, "a `person' is defined as `a human being who has been born and is alive.'" Id., at 67, 757 A.2d 699, quoting New York Penal Law ง 125.05(1) (McKinney 1998). The trial court also observed that "[t]he Model Penal Code defines a `human being' as `a person who has been born and is alive.'" State v. Courchesne, supra, at 67, 757 A.2d 699; see Model Penal Code ง 210.0(1) (1980). On the basis of these definitions and this court's past reliance on the New York Penal Law and Model Penal Code in construing this state's Penal Code, the trial court concluded that that "the definition of a `person' in Connecticut criminal law includes those who are born and are alive." State v. Courchesne, supra, at 67, 757 A.2d 699. The court further concluded that this definition did not exclude Antonia because the physician who delivered her, Palmer, had testified at the probable cause hearing that Antonia "was born and remained alive for forty-two days before she succumbed to her injuries." Id.

In reaching its determination, the trial court also relied on the common-law born alive rule. See id., at 67-69, 757 A.2d 699. The court explained that, under that rule, "the death of a fetus could stand as a basis for murder as long as the fetus was born alive and subsequently died of injuries inflicted in utero." Id., at 68, 757 A.2d 699. The court further observed that the born alive rule previously had been recognized in this state in State v. Anonymous (1986-1), 40 Conn.Supp. 498, 516 A.2d 156 (1986) (Anonymous). See State v. Courchesne, supra, 46 Conn.Supp. at 67, 757 A.2d 699. In Anonymous, the court relied on the born alive rule in denying the state's application for a warrant to arrest the defendant, who had been accused of murder in connection with the death of "an unborn but viable fetus...." State v. Anonymous (1986-1), supra, at 498-500, 502-503, 505, 516 A.2d 156. The trial court in the present case therefore rejected the defendant's contention that application of the born alive rule violated his due process right to fair notice because Antonia was a fetus when the defendant inflicted her fatal injuries, and, therefore, he had no reason to know that her subsequent death could give rise to a cognizable offense, namely, murder or capital felony. See State v. Courchesne, supra, at 71-72, *36 757 A.2d 699. The court explained that the born alive rule has deep roots in the common law and that the legislature's codification of the criminal law had not altered the rule in any way. Id., at 71, 757 A.2d 699. For these same reasons, the court rejected the defendant's claim that application of the rule constituted an unconstitutional ex post facto law, concluding that "the rule [that] applies to establish the defendant's liability was not created after he acted.... To apply the born alive rule to this defendant, therefore, would not make more burdensome the punishment for a crime, after its commission [in violation of the ex post facto clause].... Collins v. Youngblood, [497 U.S. 37, 42, 110 S.Ct. 2715, 111 L.Ed.2d 30 (1990)]." (Citation omitted; internal quotation marks omitted.) State v. Courchesne, supra, at 72, 757 A.2d 699. Finally, with respect to the defendant's claim that the state had failed to demonstrate the necessary "concurrence between the mens rea and the actus reus of the charged offenses"; id., at 73, 757 A.2d 699; the trial court observed that "[t]he intent required by ง 53a-54a(a) [this state's murder statute] may be supplied under the doctrine of transferred intent. The clear meaning of the statute leads to the result that, when a person engages in conduct with the intent to kill someone, there can be a separate count of murder for every person actually killed by the conduct. State v. Hinton, [227 Conn. 301, 309, 630 A.2d 593 (1993)]." (Internal quotation marks omitted.) State v. Courchesne, supra, at 74, 757 A.2d 699. The court concluded that there was nothing in our statutory scheme to prevent the state from relying on the principle of transferred intent for the purpose of establishing that the defendant had the mental state necessary to support a conviction of the murder of Antonia even though the injuries that caused her death were inflicted while she was in utero. Id., at 74-75, 757 A.2d 699.

Thereafter, the defendant waived his right to a jury trial for purposes of the guilt phase of the case, and his case was tried before the panel. On September 17, 2001, following that trial, the panel issued a written decision finding the defendant guilty of all charges. With respect to the counts of the information relating to Antonia's murder, the panel found that the definition of "person" under Connecticut law "includes those who are born and are alive," and, therefore, for purposes of ง 53a-3(1), a human being is "a person who has been `born alive.'" After observing that "[t]he law of the case is consistent with this ... [conclusion]," the panel further stated that "the state has proven beyond a reasonable doubt that Antonia ... was born alive" and, consequently, that she is "a person" within the meaning of this state's murder and capital felony statutes. The panel further explained that the state had proven that the defendant, with the intent to cause the death of Rodgers, had caused the death of Antonia in violation of the provision of ง 53a-54a(a) pursuant to which a person is guilty of murder "when, with intent to cause the death of another person, he causes the death ... of a third person ...." (Emphasis added.)

The defendant subsequently filed a motion for articulation of several legal conclusions and factual findings made by the panel in its written decision. The panel granted the motion only as to one legal conclusion,^[31] namely, "[t]he legal basis for *37 [the] adoption of the born alive rule and what [the panel] meant when it referred to `the case law' and `the law of the case.' ... The defendant requests that [the panel] articulate both the meaning and significance of `the case law' and `the law of the case,' and to what extent, if at all, [the panel] adopted [the] ... analysis and ruling [of the court, Damiani, J.] on the [born alive] issue." In its articulation, the panel stated that the term "`[l]aw of the case' refers to prior decisions made during the course of this case" and that, under that doctrine, "when a matter has previously been ruled [on] interlocutorily, the court in a subsequent proceeding in the case may treat that decision as the law of the case." The panel then observed that the court, Damiani, J., had resolved the issue of the born alive rule as it applies to murder and capital felony "in a well thought out [and] comprehensive opinion," and that the panel had adopted the court's reasoning and analysis in concluding that the defendant was guilty of those offenses insofar as they pertained to the murder of Antonia.

Before turning to the merits of the defendant's claims, we first set forth the applicable standard of review.^[32] "A motion to dismiss ... properly attacks the jurisdiction of the court, essentially asserting that the [state] cannot as a matter of law and fact state a cause of action that should be heard by the court...." (Internal quotation marks omitted.) State v. Cyr, 291 Conn. 49, 56, 967 A.2d 32 (2009). "A motion to dismiss tests, inter alia, whether, on the face of the record, the court is without jurisdiction.... [O]ur review of the trial court's ultimate legal conclusion and resulting [decision to deny] ... the motion to dismiss will be de novo." (Internal quotation marks omitted.) State v. Haight, 279 Conn. 546, 550, 903 A.2d 217 (2006).

The defendant's claim also raises an issue of statutory interpretation over which our review is plenary. E.g., Stiffler v. Continental Ins. Co., 288 Conn. 38, 42, 950 A.2d 1270 (2008). "When construing a statute, [o]ur fundamental objective is to ascertain and give effect to the apparent intent of the legislature.... In other words, we seek to determine, in a reasoned manner, the meaning of the statutory language as applied to the facts of [the] case, including the question of whether the language actually does apply.... In seeking to determine the meaning, General Statutes ง 1-2z directs us first to consider the text of the statute itself and its relationship to other statutes. If, after examining such text and considering such relationship, the meaning of such text is plain and unambiguous and does not yield *38 absurd or unworkable results, extratextual evidence of the meaning of the statute shall not be considered.... When a statute is not plain and unambiguous, we also look for interpretive guidance to the legislative history and circumstances surrounding its enactment, to the legislative policy it was designed to implement, and to its relationship to existing legislation and common law principles governing the same general subject matter...." (Internal quotation marks omitted.) Id., at 43, 950 A.2d 1270. "[W]hen the statute being construed is a criminal statute, it must be construed strictly against the state in favor of the accused." State v. Cardwell, 246 Conn. 721, 739, 718 A.2d 954 (1998). Furthermore, "[w]e are mindful ... that, [i]n determining whether ... a statute abrogates or modifies a common law rule the construction must be strict, and the operation of a statute in derogation of the common law is to be limited to matters clearly brought within its scope.... Thus, [n]o statute is to be construed as altering the common law, farther than its words import [and a statute] is not to be construed as making any innovation [on] the common law which it does not fairly express.... We recognize only those alterations of the common law that are clearly expressed in the language of the statute because the traditional principles of justice [on] which the common law is founded should be perpetuated." (Citations omitted; internal quotation marks omitted.) Ames v. Commissioner of Motor Vehicles, 267 Conn. 524, 532, 839 A.2d 1250 (2004); see also State v. Floyd, 217 Conn. 73, 94, 584 A.2d 1157 (1991) (recognizing in context of criminal case that "[i]t is a commonplace of statutory construction that statutes in derogation of the common law should not be construed to alter the common law further than their words demand"). Thus, "[i]t is assumed that all legislation is interpreted in light of the common law at the time of its enactment." (Internal quotation marks omitted.) Hunte v. Blumenthal, 238 Conn. 146, 153, 680 A.2d 1231 (1996). Accordingly, this court frequently has interpreted our criminal statutes and rules in light of common-law principles. See, e.g., State v. Salamon, 287 Conn. 509, 536-40, 949 A.2d 1092 (2008) (kidnapping statute); State v. Skakel, 276 Conn. 633, 691-93, 888 A.2d 985 (2006) (criminal statute of limitations), cert. denied, 549 U.S. 1030, 127 S.Ct. 578, 166 L.Ed.2d 428 (2006); State v. Scott, 256 Conn. 517, 533-34, 779 A.2d 702 (2001) (sexual assault statutes); State v. Miranda, 245 Conn. 209, 222-26, 715 A.2d 680 (1998) (assault statute), overruled on other grounds by State v. Miranda, 274 Conn. 727, 734, 878 A.2d 1118 (2005); State v. Guess, supra, 244 Conn. at 771-76, 715 A.2d 643 (murder statute); Ullmann v. State, 230 Conn. 698, 705-708, 647 A.2d 324 (1994) (criminal contempt statute); State v. Ross, 230 Conn. 183, 196-200, 646 A.2d 1318 (1994) (territorial jurisdiction of court over capital felony offenses), cert. denied, 513 U.S. 1165, 115 S.Ct. 1133, 130 L.Ed.2d 1095 (1995); State v. Kulmac, 230 Conn. 43, 52-53, 644 A.2d 887 (1994) (rape shield and risk of injury statutes); State v. Sanchez, 204 Conn. 472, 477-82, 528 A.2d 373 (1987) (perjury statute). Thus, the issue is "whether the principle should be recognized as a matter of policy under the circumstances of [the particular] case." State v. Miranda, supra, 245 Conn. at 221, 715 A.2d 680.

With these principles in mind, we commence our review of the defendant's claim with an examination of the relevant statutory language. General Statutes ง 53a-54a(a) provides in relevant part that "[a] person is guilty of murder when, with intent to cause the death of another person, he causes the death of such person or of a third person...." "Person" is defined for the purpose of the homicide statutes as *39 a "human being...." General Statutes ง 53a-3(1). The term "human being," however, is not defined statutorily. Moreover, as the trial court correctly observed, the legislative history of the relevant statutory provisions, including งง 53a-3(1) and 53a-54a(a), offers no guidance with respect to the issue raised by the present case, namely, whether a person who murders a pregnant woman also may be found guilty of the murder of the baby if the baby is born alive and later dies from injuries inflicted while the baby is in utero, in the course of the intentional killing of the mother.^[33]

When the language and legislative history of a criminal statute do not resolve the question of statutory interpretation presented by a particular case, this court "may turn to the parallel statutory provisions set forth in the Model Penal Code and the [revised] New York ... Penal Law, effective September 1, 1967, for guidance"; (internal quotation marks omitted) State v. Havican, 213 Conn. 593, 601, 569 A.2d 1089 (1990); because "[t]he drafters of [our Penal Code] relied heavily [on] the Model Penal Code and various state criminal codes, especially the [P]enal [Law] of New York. Conn. Joint Standing Committee Hearings, Judiciary, Pt. 1, 1969 Sess., p. 11." State v. Hill, 201 Conn. 505, 516-17, 523 A.2d 1252 (1986); see also State v. Henry, 253 Conn. 354, 363, 752 A.2d 40 (2000) ("[w]e note that our Penal Code is modeled after the New York Penal [Law]"); State v. Desimone, 241 Conn. 439, 456, 696 A.2d 1235 (1997) (legislature relied on "the interpretations of the American Law Institute's Model Penal Code and the New York [P]enal [Law] ... when it revised the state [P]enal [C]ode in 1969" [internal quotation marks omitted]); State v. Anonymous (1986-1), supra, 40 Conn. Supp. at 500, 516 A.2d 156 ("[t]he murder section of [this state's] [P]enal [C]ode was based partly on the [revised] New York... Penal Law and partly on the Model Penal Code" [internal quotation marks omitted]). The New York Penal Law defines "person" as "a human being who has been born and is alive." New York Penal Law ง 125.05(1) (McKinney 2009).^[34] The Model Penal Code defines "human being" as "a person who has been born and is alive...." Model Penal Code ง 210.0(1) (1980). Thus, even a viable fetus that succumbs to injuries inflicted in utero before being born alive is not a person within the meaning of the New York Penal Law and the Model Penal Code.^[35] Notably, *40 moreover, New York courts have concluded that an infant who is born alive and then dies from injuries sustained in utero is a person under that state's homicide statutes. See, e.g., People v. Hall, 158 App.Div.2d 69, 71-76, 557 N.Y.S.2d 879, appeal denied, 76 N.Y.2d 940, 564 N.E.2d 679, 563 N.Y.S.2d 69 (1990).

We also look for interpretive guidance to common-law principles governing the same general subject matter.^[36] "At common law it is clear that only *41 a living human being could be the victim of a homicide. To become a human being within the meaning of homicide statutes at common law, a child had to be born alive and have an existence independent of and separate from its mother.... The `born alive' rule dates back to at least the [seventeenth] century when the great common lawyer, Sir Edward Coke, wrote that the killing of an unborn quickened child `is a great misprision and no murder.' ... The `born alive' requirement was reiterated [in the eighteenth century] by [Sir William] Blackstone in [his common-law treatise entitled] Commentaries [on the Laws of England].... As has been elsewhere thoroughly documented, Blackstone had tremendous impact on the development of the common law in the original American colonies and in the early states of this ... country. By 1850, the `born alive' rule had widespread general acceptance by all jurisdictions in the United States [that] had considered the issue." (Citations omitted.) State v. Soto, 378 N.W.2d 625, 628 (Minn. 1985); see also C. Forsythe, "Homicide of the Unborn Child: The Born Alive Rule and Other Legal Anachronisms," 21 Val. U.L.Rev. 563, 595-96 (1987).

"In its simplest statement, the `born alive rule' prescribes that only one who has been born alive can be the victim of homicide. Causing the death of a fetus, whether viable or not, was not considered homicide at common law. If, however, the fetus was born and then died of injuries inflicted prior to birth, a prosecution for homicide could be maintained. Requirements for proof of live birth were ... stringent: `the fetus must have been totally expelled from the mother and have shown clear signs of independent vitality.'" Commonwealth v. Booth, 564 Pa. 228, 240, 766 A.2d 843 (2001). "At least two reasons, both deriving from the state of medical knowledge in centuries past, may be discerned for such requirements. First, owing to the high incidence of prenatal mortality and stillbirths, it was exceedingly difficult to determine that a fetal death or stillbirth had resulted from a defendant's act and not from natural causes. Second, because the fetus was considered to be dependent [on], and therefore essentially a part of, its mother, a prosecution for homicide could not be maintained unless it could be shown that the fetus had become a person separate from its mother." Id., at 241, 766 A.2d 843. As one court in Australia recently explained: "The law presumed that all children were born dead and the fact of live birth had to be established by evidence.... Usually such proof was not difficult, *42 but problems arose when a child died soon after birth and there was no, or little, direct evidence of what had happened at or immediately after birth." (Citations omitted.) Regina v. Iby, 63 N.S.W.L.R. 278, 283-84, 154 A.Crim. R. 55 (New South Wales Crim.App.2005).

The commentaries of one of Connecticut's most prominent legal scholars, former Chief Justice Zephaniah Swift, a member of this court from 1808 until 1819, reveal that the born alive rule was a component of the state's homicide laws from its earliest days. See 2 Z. Swift, A System of the Laws of the State of Connecticut (1796) p. 299. In his scholarly and authoritative treatise on Connecticut law, Swift states: "The [s]tatute respecting murder enacts, that if any person shall commit any wilful murder, upon malice, hatred or cruelty, not in a man's just and necessary [defense], nor by casualty against his will, or shall slay or kill another through guile, or by poisoning, or other such atrocious practices, he shall be put to death. The common law definition of murder is when a person of sound memory and discretion, unlawfully killeth any reasonable creature in being, and in the public peace, with malice aforethought, either express or implied. It is evident that the statute is made in affirmance of the common law....

"The person killed, to constitute murder, must be actually in existence. To kill a child in its mother's womb, is not murder, but a great misdemeanor, but if the child be born alive, and then die by reason of the injury it suffered in the womb, it will be murder in him who caused it." Id., at pp. 298-99. A similar assertion concerning the vitality of the born alive rule also is contained in a second commentary, namely, A Digest of the Laws of the State of Connecticut, that also was originally authored by Swift. Swift stated therein: "Felonious [h]omicide is of two kinds, [m]urder and [m]anslaughter. Murder is defined to be where a person of sound memory, and discretion, unlawfully kills any reasonable creature, in being, and in the peace, with malice aforethought express or implied....

"To constitute murder the party killed must be a reasonable being, alive and in the peace. Therefore to take a potion in order to procure an abortion or to administer it, to a pregnant female with the same design, or to strike her so that the child is killed, is not murder at common law, because [the child] is not in existence, and the circumstance of its death cannot be ascertained with sufficient precision: but if the child be born alive, and afterwards die[s] by reason of the violence it has received before its birth, it seems to be the better opinion that it will be murder in the party who inflicted it."^[37] 2 Z. Swift, A Digest of the Laws of the State of Connecticut (1823) p. 267. Furthermore, although the issue is one of first impression for this court, trial courts in this state previously have applied the born alive rule, or a rule akin to the born alive rule, in concluding that a fetus that is born alive despite having suffered injuries in utero as a result of the negligence of another person has a cause of action against the wrongdoer; Simon v. Mullin, 34 Conn.Supp. 139, 147, 380 A.2d 1353 (1977) (any fetus regardless of viability); Tursi v. New England Windsor Co., 19 Conn.Supp. 242, 248, 111 A.2d 14 (1955) (viable fetus); and that a viable fetus that is injured in utero but dies before being born is not a person within the meaning of the state's homicide statutes. See State v. Anonymous *43 (1986-1), supra, 40 Conn.Supp. at 499, 516 A.2d 156. In addition, in In re Valerie D., 25 Conn.App. 586, 595 A.2d 922 (1991), rev'd on other grounds, 223 Conn. 492, 613 A.2d 748 (1992), the Appellate Court quoted Anonymous with approval, noting, inter alia, that the court in Anonymous had declined to treat an unborn child as a person for purposes of our Penal Code because, under the code, a person includes only those who have born alive. Id., at 591, 595 A.2d 922.

In ascertaining the common law, we also look to the decisions of other jurisdictions. E.g., Rogers v. Tennessee, 532 U.S. 451, 464, 121 S.Ct. 1693, 149 L.Ed.2d 697 (2001) ("[c]ommon law courts frequently look to the decisions of other jurisdictions in determining whether to alter or modify a common law rule in light of changed circumstances, increased knowledge, and general logic and experience"); State v. Miranda, 260 Conn. 93, 107, 794 A.2d 506 (same), cert. denied, 537 U.S. 902, 123 S.Ct. 224, 154 L.Ed.2d 175 (2002); see also Pacific Indemnity Ins. Co. v. Aetna Casualty & Surety Co., 240 Conn. 26, 30, 688 A.2d 319 (1997) ("[a]lthough this court has not previously addressed [the common-law issue presented], we find guidance in the decisions of other jurisdictions"). As one court has noted, "[c]ourts in other jurisdictions have also consistently concluded that the death of an infant who is born alive from injuries inflicted in utero constitutes homicide. See, e.g., United States v. Spencer, 839 F.2d 1341, 1343-44 [9th Cir.] (kicking and stabbing of mother resulting in death of infant ten minutes after birth was killing of `human being') [cert. denied, 487 U.S. 1238, 108 S.Ct. 2908, 101 L.Ed.2d 939 (1988)]; Ranger v. [State], 249 Ga. 315, [317, 290 S.E.2d 63] (1982) (death of child, twelve hours after birth, caused by shooting of mother sufficient to sustain conviction for felony murder of child); [People] v. Bolar, 109 Ill. App.3d 384, [389-92, 64 Ill.Dec. 919, 440 N.E.2d 639] (1982) (newborn surviving only long enough to exhibit a few heartbeats `individual' within meaning of manslaughter and reckless homicide statutes); Jones v. [Commonwealth], 830 S.W.2d 877, 880 [Ky.1992] (infant who died from prenatal injuries fourteen hours after birth was `person' within [meaning of] criminal homicide statutes); Williams v. [State], 316 Md. 677, [682-83, 561 A.2d 216] (1989) (death of child seventeen hours after birth from arrow wound [to] mother supported manslaughter conviction); [State] v. Anderson, 135 N.J.Super. 423, [429, 343 A.2d 505 (1975)] (twins who died within hours of birth `persons' within meaning of homicide laws); People v. Hall, [supra, 158 App.Div.2d at 76-78, 557 N.Y.S.2d 879] (infant who died thirty-six hours after birth due to prenatal shooting of mother [was] `person' within meaning of homicide statutes); Cuellar [v. State], 957 S.W.2d 134 [140 (Tex.App.1997)] (infant who died forty-three hours after birth from injuries suffered by mother in car crash `individual' within meaning of manslaughter statute).

"Although some of those decisions were based [on] statutes expressly defining homicide to include the deaths of those who have been born alive, the absence of such language does not dictate a contrary interpretation. In [State] v. Cornelius, 152 Wis.2d 272, [448 N.W.2d 434 (App.1989)], the defendant argued that, notwithstanding the inclusion of the born alive rule in the statutory definition of `human being,' he could not be prosecuted for homicide for the death of a child resulting from the infliction of prenatal injuries. [Id., at 279, 448 N.W.2d 434.] In rejecting the claim, the court noted that Wisconsin (like Arizona [and Connecticut]) had abolished common law crimes in favor of a criminal code. See [id.] Nevertheless, the *44 court observed that common law rules not in conflict with the code were retained ... and thus concluded that it would have employed the born alive rule in interpreting the homicide statute even absent a statutory reference to the rule. See id." State v. Cotton, 197 Ariz. 584, 589, 5 P.3d 918 (App.2000); see also id., at 586, 590-91, 5 P.3d 918 (infant who died twenty-four hours after birth from injuries sustained in utero when mother was shot in head was "person" within meaning of Arizona homicide statutes). This is true in Connecticut, as well. See, e.g., Gore v. People's Savings Bank, 235 Conn. 360, 382, 665 A.2d 1341 (1995) (statute shall not be construed as altering common law unless statutory language clearly so requires); Dart & Bogue Co. v. Slosberg, 202 Conn. 566, 573, 522 A.2d 763 (1987) (statutory construction "begins with the presumption that statutory and common law should, [whenever] possible, be read in harmony"). As we previously have observed, moreover, "the common law of England ... was brought here by the first settlers, and became the common law of Connecticut so far as it was not unadapted to the local circumstances of this country." (Citations omitted.) Graham v. Walker, 78 Conn. 130, 133, 61 A. 98 (1905). Thus, at times, "[this court's] view of the relationship of the common law of England to the law of Connecticut has been conspicuous by its ambivalence"; Dacey v. Connecticut Bar Assn., 184 Conn. 21, 25, 441 A.2d 49 (1981); and, consequently, "the common law of England prior to 1776 does not necessarily represent the common law of this state...." (Citation omitted; emphasis added.) Id. "As our jurisprudence developed [however], the courts applied the principles of the [English] common law to the decision of causes, so far as they seemed applicable to our social conditions...."^[38]Brown's Appeal from Probate, 72 Conn. 148, 151, 44 A. 22 (1899). The defendant has offered no reason, and we know of none, why the born alive rule would not have been accepted as the law of this state at the time of its settlement,^[39] just as the rule was *45 accepted by virtually every jurisdiction that had considered it.^[40] Put differently, *47 there was no ambivalence in Connecticut toward the born alive rule. To the contrary, the writings of former Chief Justice Swift indicate that it was, in fact, regarded as a governing legal principle in this state.^[41] We, therefore, must *48 presume that the legislature did not intend to abrogate the rule when it enacted the Penal Code in 1971.^[42] Indeed, in the absence of legislation "expressly including *49 a fetus within the definition of victims of homicide or [the passage of] a separate feticide statute ... no court of last resort in this country [had] held [prior to the enactment of our Penal Code] that the killing of a fetus is murder unless the fetus is born alive and then expires."^[43] (Citations omitted.) People v. Greer, 79 Ill.2d 103, 111, 37 Ill.Dec. 313, 402 N.E.2d 203 (1980). Accordingly, we recognize the *50 rule in the absence of a persuasive reason to the contrary.^[44]

As the defendant correctly notes, recent advances in medical science have prompted a number of state courts to depart from the born alive rule in favor of a rule of viability, under which "a viable fetus can be the victim of a homicide," regardless of whether it is born alive. (Emphasis added.) Commonwealth v. Morris, 142 S.W.3d 654, 660 (Ky.2004); see also, e.g., Hughes v. State, 868 P.2d 730, 731 (Okla.Crim.App.1994) (viable fetus is "human being" under statute defining homicide as intentional killing of "human being"); Commonwealth v. Cass, 392 Mass. 799, 807, 467 N.E.2d 1324 (1984) (viable fetus is "person" under vehicular homicide statute barring certain conduct that causes death of "another person"); State v. Horne, 282 S.C. 444, 446-47, 319 S.E.2d 703 (1984) (viable fetus is "person" within meaning of statute defining murder as killing of "any person"). These courts generally have concluded that "the rationale for the `born alive' rule no longer exists" because "[m]edical science has now advanced to the stage that the viability, health, and cause of a [fetus'] death can be determined."^[45]Commonwealth v. Morris, supra, at 659; see also Commonwealth v. Cass, supra, at 806, 467 N.E.2d 1324 ("[m]edical science now may provide competent proof as to whether the fetus was alive at the time of a defendant's conduct and whether his conduct was the cause of death"). Furthermore, according to the National Conference of State Legislatures, thirty-eight states have abrogated the born alive rule legislatively by the enactment of laws that classify the killing of a viable fetus as a homicide.^[46] See National Conference of State Legislatures, Fetal Homicide Laws (March, 2010), available at *51 http://www.ncsl.org/programs/health/ fethom.htm (last visited May 27, 2010).

Notwithstanding the recent trend in other jurisdictions toward recognizing a viable fetus as a person for purposes of the homicide statutes of those jurisdictions,^[47] several states have elected to treat the killing of a fetus, including a viable fetus, as a *52 form of aggravated assault inflicted on the mother rather than as a homicide.^[48] Connecticut is one of those states. In 2003, the legislature enacted Public Acts 2003, No. 03-21 (P.A. 03-21), entitled "An Act Concerning Assault of a Pregnant Woman," which is codified as amended at General Statutes ง 53a-59c. Public Act 03-21 provides in relevant part: "(a) A person is guilty of assault of a pregnant woman resulting in termination of pregnancy when such person commits assault in the first degree ... and (1) the victim of such assault is pregnant, and (2) such assault results in the termination of pregnancy that does not result in a live birth....

"(c) Assault of a pregnant woman resulting in termination of pregnancy is a class A felony."

Public Act 03-21, also known as "Jenny's Law," was enacted in response to the December 31, 2001 murder of Jenny McMechen, who was thirty-six weeks pregnant at the time she was shot to death by Michael Latour. See State v. Latour, 276 Conn. 399, 401, 886 A.2d 404 (2005). Because the fetus she was carrying died in utero, the born alive rule operated to bar the state from treating the death of the fetus as murder, and, presumably as a consequence, Latour was charged with only one count of murder, that is, the murder of McMechen. See id. Indeed, at the time McMechen was murdered, our Penal Code contained no provision pertaining to the killing of a fetus that dies in utero. McMechen's family petitioned state lawmakers to enact legislation recognizing an unborn fetus as a person for purposes of this state's homicide statutes. See, e.g., Conn. Joint Standing Committee Hearings, Judiciary, Pt. 9, 2002 Sess., pp. 2797, 2806-2807. In response, Raised House Bill No. 5747 (2002), entitled "An Act Concerning the Definition of a Person in the Penal Code," was referred to the judiciary committee on March 13, 2002. Section 1 of the bill provided that the term "`person', when used to describe the victim of [a homicide], includes a viable fetus." A public hearing on the bill was held on March 18, 2002, at which numerous people testified *53 both for and against the bill. See, e.g., Conn. Joint Standing Committee Hearings, Judiciary, Pt. 8, 2002 Sess., pp. 2307-18, 2402-39. At the hearing, Representative Michael P. Lawlor, the judiciary committee cochairperson, explained that the state historically had used the word "person" in its criminal statutes and that had not changed since the "[s]tate was chartered" in the 1600s. Id., at p. 2405. He indicated, moreover, that he opposed expanding the definition of "person" under the homicide statutes to include a fetus because, among other reasons, it would create another death penalty eligible offense. Id., at p. 2429.

Clarke D. Forsythe, president of Americans United for Life and a leading opponent of the common-law born alive rule,^[49] spoke in favor of the bill. Id., at pp. 2402-17. Forsythe argued that, "[o]ver the past several years a number of criminal assaults in Connecticut resulting in the death of unborn human beings have demonstrated that no remedy exists in the criminal law and that legislation is needed.

"The lack of remedy in the law is due to the outdated and obsolete common law born alive rule which prevents a charge of homicide when a child is stillborn after an assault. At common law, the killing of an unborn human was not treated as a homicide unless the child was born alive and died thereafter and born alive does not mean term birth, it doesn't mean [forty] weeks gestation. It simply means expulsion from the womb at any time of pregnancy.

"It is a rule of location, a rule of evidence... that has no gestation[al] time limitation and thus, a charge of homicide can be brought if a criminal assault results in miscarriage at any time [during] gestation, as long as the child dies after expulsion from the womb....

"[W]hile [the rule] may have made medical sense four centuries ago when it was created in 1601 in English courts, it has been rendered obsolete by modern medical science. With modern medical science, the application of the born alive rule leads to absurd results. Here in Connecticut, a prenatal assault that results in a miscarriage and death after birth at one month gestation can be charged as a homicide even though the fetus is only a month old. While a prenatal assault, as in the case of... McMechen, at eight months or nine months that results in a stillbirth, can never result in a charge of homicide." (Emphasis added.) Id., at pp. 2403-2404; see also id., at pp. 2417-19, remarks of Bill O'Brien, legislative vice president of Connecticut Right to Life Corporation. Thus, those testifying in favor of the bill acknowledged that its passage would serve to abrogate the born alive rule, which, they also acknowledged, was embodied in the common law of this state. Members of the judiciary committee both for and against the bill questioned these witnesses at some length in an effort to understand the rationale underlying the bill, its ramifications, and the extent to which other states had enacted similar legislation.^[50]

*54 Many abortion rights organizations testified against the bill. For example, Elaine C. Werner, executive director of the Connecticut affiliate of the National Abortion and Reproductive Rights Action League, argued that, "[b]y focusing on creating a separate legal status for fetuses, rather than whether the bill would actually deter criminal conduct, I fear the promotion of a political agendaโ€”an agenda that has nothing to do with violence against pregnant women.... Although presented as crime fighting, it is actually aimed at eroding a woman's constitutional right under Roe v. Wade."^[51] Conn. Joint Standing Committee Hearings, Judiciary, Pt. 9, 2002 Sess., p. 2809. Lisa B. Winjum, director of public policy and communication for Connecticut Sexual Assault Crisis Services, Inc., stated that the "bill opens the door to numerous legal and public policy concerns in the areas of privacy and reproductive freedom." Id., at p. 2783. Winjum stated further: "We strongly oppose the bill because it will not do anything to prevent violence against women. Nor will it save a single life. Those who seek to undermine a woman's right to privacy and reproductive freedom continually try to separate the legal rights of the fetus from the legal rights of the mother."^[52] Id. Jennifer C. Jaff, an attorney, argued that the bill was "bad public policy" predicated on the false premise "that the interests of the woman and those of the fetus developing inside her body can be separated when, in fact, they are inextricably joined." Id., at p. 2785. In light of the strong opposition to the bill, it was not reported out of the judiciary committee.

On April 9, 2002, Substitute House Bill No. 5747, entitled "An Act Concerning Assault of a Pregnant Woman," was reported favorably out of the judiciary committee. The substitute bill was described by one Senator as a "compromise" between the pro-life and pro-choice groups. See 46 S. Proc., Pt. 4, 2003 Sess., p. 1013, remarks of Senator Catherine W. Cook; see also id., at p. 1010, remarks of Senator Donald E. Williams, Jr. (noting "broad support" for substitute bill and describing "unique alliance" between pro-choice and pro-life groups in supporting proposed legislation). Although the House passed the substitute bill, the Senate never acted on it before the expiration of the 2002 legislative session.

The substitute bill was resurrected in the 2003 session as Senate Bill No. 355. A hearing on the bill was held on February 10, 2003. Susan Lloyd Yolen, chairperson of the Connecticut Coalition for Choice, testified that "the language contained in [the bill] is the positive result of compromise that took place last [s]ession. In the generally acrimonious battle over reproductive rights, which has often centered on the questions of what status and rights are accorded to the fetus, the wording of this bill stands as a rare example of accord. Sponsors of last year's bill assured the pro-choice community that it was not their intent to establish language that would erode abortion rights ... [but that] would help mitigate the injustice done when a *55 woman, pregnant with a wanted child, is harmed or killed by an assailant, and her pregnancy is ended. The resulting language was the result of a good faith effort to reach agreement on an approach that would suitably punish the perpetrator by making such an assault a class A felony." Conn. Joint Standing Committee Hearings, Judiciary, Pt. 2, 2003 Sess., p. 521.

Although many of those who had testified the previous year in support of the 2002 bill also testified in support of the 2003 bill, some complained that the bill did not go far enough because it did not define the term "person" in our Penal Code to include a viable fetus and, thus, did not serve to abolish the born alive rule. For example, O'Brien testified that the bill "continues Connecticut's adherence to [the] medically obsolete ... born alive rule which was [recognized] in 1601." Id., at p. 424. O'Brien explained that "[a] child no longer needs to be born alive for science to prove whether or not the child was alive at a certain time in the womb" and implored the legislature to "move Connecticut's courts and the law out of the [1600s] and abandon the born alive rule to join other more technologically sophisticated states in the [twenty-first] century in using modern medical science to determine if an unborn child's injuries or death resulted from some natural cause or from an assault." Id.; see also id., at pp. 668-69, 671, remarks of Clarke Forsythe (arguing that "the [l]egislature should abolish the obsolete and outdated born alive rule in Connecticut" and suggesting different language in 2003 bill that would serve to abolish rule while protecting reproductive freedoms of women). Thus, some continued to advocate for the abolition of the born alive rule, and members of the judiciary committee continued to be actively involved in that discussion.^[53]

Ultimately, the legislature opted to treat the assault of a pregnant woman that results in the termination of her pregnancy without a live birth as an aggravated assault on the pregnant woman, and not as a homicide of the fetus, irrespective of whether the fetus was viable when the pregnancy was terminated. See P.A. 03-21. By its express terms, P.A. 03-21 applies only to "the termination of [a] pregnancy that does not result in a live birth," language that clearly reflects the legislature's awareness that it was carving out an exception for an infant who is born alive but who thereafter dies from injuries sustained in utero. The reason for this exception could hardly be clearer in light of the legislative debate that preceded the enactment of P.A. 03-21, namely, the legislature's recognition that an infant who is born alive but subsequently dies from injuries sustained in utero already is protected by virtue of the operation of the born alive rule, pursuant to which the infant's death is treated as a homicide.^[54]

*56 As the foregoing statutory language and legislative history reveal, it is abundantly clear that, in enacting P.A. 03-21, the legislature fully considered and rejected the possibility of abolishing the born alive rule and adopting a viability rule instead. In fact, a report on P.A. 03-21 prepared by the legislature's office of legislative research indicates that the legislature, in making its determination, was well aware of the trial court's express reliance on the born alive rule in the present case, as well as the application of the rule by the court in State v. Anonymous (1986-1), supra, 40 Conn.Supp. at 498, 516 A.2d 156.^[55] See Office of Legislative Research, Research *57 Report No. 2003-R-0488, "Assault of a Pregnant Woman and Murder" (June 30, 2003) (discussing present case and Anonymous, and specifically referring to fact that born alive rule was "applied" by trial court in present case), available at http://www.cga.ct.gov/2003/olrdata/jud/rpt/ 2003-R-0488.htm (last visited May 27, 2010). "Although the comments of the office of legislative research are not, in and of themselves, evidence of legislative intent, they properly may bear on the legislature's knowledge of interpretive problems that could arise from a bill." Harpaz v. Laidlaw Transit, Inc., 286 Conn. 102, 124 n. 15, 942 A.2d 396 (2008); cf. State v. Tabone, 279 Conn. 527, 542, 902 A.2d 1058 (2006) (consulting analysis of bill by office of legislative research to ascertain legislative intent). The report provides in relevant part: "[Public Act] 03-21 creates a new crime of assault of a pregnant woman. The act makes it a class A felony (punishable by [ten] to [twenty-five] years in prison) for anyone to assault a pregnant woman and cause her pregnancy to terminate without a live birth....

"This new crime does not affect the murder statutes. Under Connecticut case law, a person cannot be charged with murder of a baby unless the baby is born alive and lives for some period of time." (Emphasis added.) Office of Legislative Research, Research Report No. 2003-R-0488, supra.

In light of the centuries old born alive ruleโ€”which, as we have explained, has been universally recognized by courts and commentators throughout the country as deeply rooted in the common lawโ€”and the passage of and legislative history surrounding P.A. 03-21, we conclude that the trial court properly determined that an infant who is born alive and who subsequently dies of injuries that he or she had sustained in utero is a "person" within the meaning of this state's homicide statutes.^[56] Although it is true, of course, that this court previously has had no occasion to consider the born alive rule, no less authoritative a commentator than former Chief Justice Swift expressly acknowledged the applicability and import of the rule more than 200 years ago.

We note, furthermore, that, under the position that the defendant advances, he would not be subject to any greater penalty because Rodgers was eight and one-half months pregnant with Antonia than he would have been if she had not been pregnant at the time of her death. This result is a necessary consequence of the defendant's contention that the born alive rule was not embodied in our statutory scheme when he attacked and killed Rodgers; the defendant would be subject to criminal liability for Rodgers' murder and nothing more. We are unwilling to presume that the legislature intended such a result, especially in light of the clear legislative history of P.A. 03-21.

Justice Zarella, like the defendant, contends that we should decline to recognize the born alive rule because it is obsolete. It is true that the rule gained widespread acceptance at a time when it was not possible to determine whether a fetus was alive in utero. In part for that reason, the law required the state to prove a live birth to guard against the possibility that the fetus was not alive when the defendant engaged in the prohibited conduct. Of course, advances *58 in medical science have now made it possible to determine whether a fetus was alive prior to that conduct, and, consequently, the born alive rule is not necessary for the purpose of proving that fact. With the removal of that evidentiary impediment, a majority of states have seen fit to abandon the rule, but they have done so in favor of statutes that treat the killing of a fetus as a form of homicide. See, e.g., A. Lotierzo, comment, "The Unborn Child, A Forgotten Interest: Reexamining Roe in Light of Increased Recognition of Fetal Rights," 79 Temp. L.Rev. 279, 284-85 n. 52 (2006). Indeed, in a few states, courts have achieved the same result in the exercise of their common-law authority. See Commonwealth v. Cass, supra, 392 Mass. at 807, 467 N.E.2d 1324 (viable fetus); State v. Horne, supra, 282 S.C. at 446-47, 319 S.E.2d 703 (viable fetus). Those jurisdictions, therefore, have repudiated the born alive rule for the purpose of expanding the protection afforded under their homicide statutes to include not only those victims who previously had been covered under the rule but, in addition, a considerably broader group of victims, that is, the class of victims comprised of viable, and in some states, previable,^[57] fetuses who have suffered fatal injuries and died in utero. In other words, those states that have rejected the born alive rule, either legislatively or judicially, have done so in the interest of protecting all viable fetuses who suffer fatal injuries, including those that are not born alive, in addition to those that are born alive but subsequently die due to injuries sustained in utero. Thus, as the Arizona Court of Appeals aptly has explained, "[a]lthough some commentators argue that the born alive rule is an anachronism in light of advances in the areas of obstetrics and forensics ... such criticism favors the applicability of homicide statutes to the deaths of unborn, but viable, children, not the inapplicability of such statutes to babies ... who are not only viable, but are in fact born alive." (Citation omitted; emphasis added.) State v. Cotton, supra, 197 Ariz. at 588 n. 5, 5 P.3d 918. In light of the reason why various states have abolished the born alive ruleโ€”that is, because it now is viewed by those states as unnecessarily underinclusive with respect to the category of victims that it protectsโ€”it would make no sense to reject the rule, as Justice Zarella contends that we should, without replacing it with a broader rule, namely, one that includes the killing of a fetus.

We are not at liberty to follow the lead of other states in adopting a broader construction of our murder statute to include the killing of a fetus, however, because, as we previously discussed, our legislature took a markedly different approach from the majority of states when, in 2003, it made it a crime under P.A. 03-21 to commit an assault against a pregnant woman that causes the termination of pregnancy that does not result in a live birth. For the reasons that follow, the enactment of P.A. 03-21 provides yet another convincing reason why recognition of the born alive rule is the only appropriate approach to take with respect to the construction of our murder *59 statute, as that statute is applied to the factual scenario presented.^[58]

It is crystal clear from the legislative history of P.A. 03-21 that the legislature took this approach because of the concern that treating a fetus as a person for purposes of our murder statute might have significant implications in the area of abortion rights. Indeed, the very same debate that preceded the enactment of P.A. 03-21 has occurred in many other states throughout the country, prompting one commentator to explain: "Analytically, this topic is a difficult oneโ€”on one hand, it is hardly controversial to take the position that a fetus is a human organism (though the legal personhood of a fetus is hotly debated) and that, consequently, the killing of a fetus should not go entirely unpunished. But, on the other hand, those advocates of constitutionally protected reproductive rights balk at classifying all unborn children as `human beings' for the purposes of homicide statutes. The challenge, then, becomes appropriately protecting pregnant mothers and their unborn children while still maintaining reproductive freedoms....

"[Consequently, before opting to recognize unborn children as potential homicide victims] the legislature must weigh very carefully a countervailing concern: the potential erosion of constitutionally protected reproductive freedoms. Many pro-choice advocates understandably worry that fetal homicide laws encroach on reproductive freedoms and could ultimately result in the outlawing of abortion altogether. Couched in these terms, it is unsurprising that many oppose passage of a fetal homicide law, not because they do not wish to protect *60 the life of a fetus, but because the issue implicates the politics of reproductive rights." D. Curran, note, "Abandonment and Reconciliation: Addressing Political and Common Law Objections to Fetal Homicide Laws," 58 Duke L.J. 1107, 1109-10 (2009).

The legislative history and debate surrounding the enactment of P.A. 03-21^[59] reveals that it was precisely this consideration that prompted the legislature to treat the killing of a fetus in utero as an aggravated assault on the mother, which the legislature accomplished by enacting P.A. 03-21, and to treat the killing of an infant who dies after being born alive from injuries sustained in utero as a murder, which the legislature accomplished by leaving the born alive rule in place. Indeed, as we noted previously, two speakers, both of whom represented pro-life groups, argued strenuously before the judiciary committee that the born alive rule was outmoded and obsolete and that it should be abolished in favor of the proposed legislation that they favored,^[60] which would have treated a viable fetus as a person under our murder statute.^[61] See Raised House Bill No. 5747 (2002). Those who spoke *61 against the born alive rule lost the argument, however, and the legislature took no action to abolish or abrogate the rule. Several legislators, moreover, expressly acknowledged that they were voting for P.A. 03-21 as a compromise between the position advocated by the pro-life activists and the position advocated by those other personsโ€”mainly pro-abortion rights activistsโ€”who initially had favored no statutory change at all. It is evident, therefore, that the legislature's enactment of P.A. 03-21 "merely reflects a desire to afford greater protection to the unborn fetus than was available under common law, not less protection to a child who, despite the homicidal conduct of another, happens to survive past birth." (Emphasis added.) State v. Cotton, supra, 197 Ariz. at 588, 5 P.3d 918. Of course, as a consequence of the enactment of P.A. 03-21, this court lacks the authority to reject the born alive rule in favor of an expansion of our murder statute to include the killing of a viable fetus that dies in utero because the legislature already has determined that such conduct shall be treated as an aggravated assault against the mother under P.A. 03-21 and not as a homicide.^[62]

Disregarding the unmistakable import of P.A. 03-21 and the legislative debate that preceded its enactment,^[63] Justice Zarella would have us reject the born alive rule as outmoded even though, in contrast to those other states that have done so, we would be barred by P.A. 03-21 from replacing it with a broader and, it is claimed, more modern and enlightened rule that encompasses the killing of a fetus in utero. The approach that Justice Zarella urges, however, simply ignores the reason why the legislature opted to preserve the born alive rule, that is, to facilitate the compromise crafted in response to the competing positions advocated by pro-life and pro-choice supporters. Thus, although we agree that the born alive rule no longer is necessary to ensure that the fetus was alive and viable when the injuries that led to its demise were inflicted, our legislature has decided to retain the rule for an altogether different reason, namely, to accommodate the concerns of pro-choice supporters who opposed treating the killing of a fetus in utero as murder.

Moreover, in light of the policy decision of the legislature that led to the enactment of P.A. 03-21, judicial abrogation of the born alive rule would lead to a result that is both unprecedented and absurd; in that event, a person who fatally injures a fetus that dies in utero would be subject to *62 severe criminal penalties under P.A. 03-21, whereas that same person would be subject to no criminal sanction for inflicting those same injuries if the fetus is born alive and subsequently dies from the injuries inflicted in utero. Of course, no state ever has approvedโ€”or ever would approve ofโ€”such a result, yet that is the result that Justice Zarella would have us achieve by rejecting the born alive rule. Justice Zarella nevertheless accuses us of "invad[ing] the legislative prerogative" and "violat[ing] the separation of powers" by declining to ascribe to the legislature such a bizarre and irrational intent. On the contrary, it is the position that Justice Zarella advocatesโ€”a position that defies both common sense and the legislative history surrounding the enactment of P.A. 03-21โ€”that would thwart the obvious intent of the legislature, that is, to classify as a homicide conduct that causes an infant to die after being born alive as a result of injuries that were inflicted in utero, on the one hand, and to classify as an aggravated assault on the mother conduct that causes a fetus to die in utero from the same injuries, on the other.

Not surprisingly, the interpretation that Justice Zarella advances violates several cardinal principles of statutory construction. For example, this court repeatedly has stated "that the legislature, in amending or enacting statutes, always [is] presumed to have created a harmonious and consistent body of law...." (Internal quotation marks omitted.) In re Judicial Inquiry No. 2005-02, 293 Conn. 247, 262, 977 A.2d 166 (2009). Moreover, "[j]ust as the legislature is presumed to enact legislation that renders the body of the law coherent and consistent, rather than contradictory and inconsistent ... courts must discharge their responsibility, in case by case adjudication, to [ensure] that the body of lawโ€”both common and statutoryโ€”remains coherent and consistent." (Internal quotation marks omitted.) Loughlin v. Loughlin, 280 Conn. 632, 644, 910 A.2d 963 (2006). Thus, "we are required to read statutes together when they related to the same subject matter.... Accordingly, [i]n determining the meaning of a statute ... we look not only at the provision at issue, but also to the broader statutory scheme to ensure the coherency of our construction." (Emphasis added; internal quotation marks omitted.) Teresa T. v. Ragaglia, 272 Conn. 734, 748, 865 A.2d 428 (2005). In other words, "[t]he General Assembly is always presumed to know all the existing statutes and the effect that its action or non-action will have [on] any one of them. And it is always presumed to have intended that effect which its action or nonaction produces." (Emphasis added; internal quotation marks omitted.) Martinez v. Dept. of Public Safety, 263 Conn. 74, 84, 818 A.2d 758 (2003). Furthermore, it is axiomatic that "those who promulgate statutes ... do not intend to promulgate statutes ... that lead to absurd consequences or bizarre results." (Internal quotation marks omitted.) Dias v. Grady, 292 Conn. 350, 361, 972 A.2d 715 (2009). Consequently, "[i]n construing a statute, common sense must be used and courts must assume that a reasonable and rational result was intended"; (internal quotation marks omitted) ATC Partnership v. Coats North America Consolidated, Inc., 284 Conn. 537, 545, 935 A.2d 115 (2007); and, further, "if there are two [asserted] interpretations of a statute, we will adopt the ... reasonable construction over [the] one that is unreasonable." (Internal quotation marks omitted.) Aspetuck Valley Country Club, Inc. v. Weston, 292 Conn. 817, 829, 975 A.2d 1241 (2009).

The statutory interpretation that Justice Zarella urges is wholly incompatible with each and every one of these fundamental *63 principles because that interpretation requires us to presume either that the legislature enacted P.A. 03-21 with the intent to achieve an absurd result or that the legislature was oblivious to the bizarre consequences of its action. For obvious reasons, neither presumption is tenable. Indeed, it is particularly indefensible to indulge in a presumption that achieves such a bizarre and irrational result when, as in the present case, an alternative interpretationโ€”one that has deep roots in the common law and is firmly predicated on the pertinent legislative history and genealogyโ€”leads to a perfectly reasonable and logical result.

Justice Zarella nevertheless seeks to justify his refusal to recognize the decision of the legislature to treat the killing of a fetus in utero as an aggravated assault on the mother and the killing of an infant who is born alive but who subsequently dies from injuries suffered in utero as a murder on the ground that this distinction "makes no sense whatsoever." This assertion is suspect if for no other reason than the fact that seventeen of our sister states still "retain some form of the born alive rule." State v. Lamy, 158 N.H. 511, 517, 969 A.2d 451 (2009); see also id., at 517 n. 3, 969 A.2d 451 (listing states that currently retain some form of born alive rule). Justice Zarella also fails to account for his inability to identify even one case that, prior to 1998, had abolished the born alive rule to reach the result that Justice Zarella would reach in the present case, that is, to exonerate a defendant who inflicts injuries on an infant in utero who is born alive but who thereafter dies from those injuries. More importantly, however, in view of the competing public policy considerations outlined previously, there is absolutely nothing irrational or nonsensical about a statutory scheme such as ours, which classifies the killing of a fetus in utero as an aggravated assault on the motherโ€”a crime punishable by a term of imprisonment of up to twenty-five yearsโ€” and the killing of an infant who is born alive but who subsequently dies from injuries suffered in utero as murder. More importantly, this court is bound to honor that legislative distinction irrespective of whether we personally agree that it represents wise or sound public policy. See, e.g., State v. Allen, 289 Conn. 550, 585, 958 A.2d 1214 (2008) (classification of crime "is a public policy determination reserved to the legislative branch of government, except [when] constitutional principles apply"); State v. Darden, 171 Conn. 677, 679-80, 372 A.2d 99 (1976) ("[t]he [state] constitution assigns to the legislature the power to enact laws defining crimes and fixing the degree and method of punishment").

Indeed, to whatever extent one reasonably might disagree with the distinction that the legislature has adopted, the classification that would result from the statutory interpretation that Justice Zarella advocatesโ€”that is, one that distinguishes the intentional killing of a fetus that dies in utero from the intentional killing of an infant who is born alive but who subsequently dies from injuries inflicted in utero by treating the former as a class A felony and the latter as no crime at allโ€”is utterly irrational. Notably, as we previously have observed, Justice Zarella has not identified any conceivable reason why the legislature would place its imprimatur on such a perverse scheme.^[64]*64 In fact, as we have explained, to conclude that the legislature has done so would require us both to disregard the manifest intent of the legislature and, in the process, to reach a truly absurd result, a course that we refuse to take.^[65]

We also find no merit to the defendant's claim that the born alive rule is inconsistent with and "thus abrogated by the Penal Code [because the code premises] criminal liability on attendant circumstances that must exist at the time the defendant [commits the criminal acts]." The defendant argues, essentially, that the legislature, in adopting the Penal Code, intended that any conduct proscribed thereunder must be perpetrated on a victim who has been born and is alive at the time of the conduct.

Under ง 53a-54a(a), a person commits the crime of murder when, with the intent to cause the death of another person, he causes the death of that person or of a third person. Thus, "the statute on its face allows transferred intent for the crime of murder without limitation as to the number of people killed. The clear meaning of the statute leads to the result that, when a person engages in conduct with the intent to kill someone, there can be a separate count of murder for every person actually killed by the conduct." (Emphasis added.) State v. Hinton, supra, 227 Conn. at 309, 630 A.2d 593. Although ง 53a-54a(a) requires that the murder victim be a "person," there is nothing in that provision requiring a temporal nexus between the victim's status as a person and the conduct that brings about the person's death.^[66] Moreover, the defendant has cited no persuasive authority, and we are aware of none, in support of his claim that such a temporal nexus is required when, as in the present case, the defendant is charged with murder arising out of the death of an infant who is born alive but who later dies from injuries sustained in utero. Indeed, virtually every court that has considered a similar challenge to the applicability of the born alive *65 rule has rejected it.^[67]

For example, in Cuellar v. State, supra, 957 S.W.2d at 134, the defendant, Frank Flores Cuellar, was convicted of manslaughter after the car that he was driving while intoxicated collided with a vehicle being driven by a woman who was seven and one-half months pregnant. Id., at 136. Because of evidence of fetal distress, medical personnel performed an emergency cesarean section in an attempt to save the baby. Although the baby survived the delivery, she died approximately two days later of injuries sustained in the collision. Id. Cuellar was charged under Texas' intoxication manslaughter statute, which provided in relevant part: "A person commits an offense if the person ... (1) operates a motor vehicle in a public place ... and (2) is intoxicated and by reason of that intoxication causes the death of another by accident or mistake." (Internal quotation marks omitted.) Id., at 137, quoting Texas Penal Code Ann. ง 49.08 (Vernon 1994). Under the Texas Penal Code, "`[a]nother' is defined ... to mean a `person,' a `person' is defined to include an `individual,' and an `individual' is defined as `a human being who has been born and is alive.'" Cuellar v. State, supra, at 137, quoting Texas Penal Code Ann. ง 1.07(5), (26) and (38) (Vernon 1994).

*66 On appeal, Cuellar claimed, inter alia, that the trial court improperly had denied his motion to dismiss the manslaughter charge on the ground that "the victim of the offense was a fetus at the time of [Cuellar's] conduct and, therefore, was not an `individual' within the legal meaning of that term." Cuellar v. State, supra, 957 S.W.2d at 136. The court noted that the case presented "the question of whether the [Texas] Penal Code authorizes a conviction only when a victim meets the definition of an individual at the time of the alleged misconduct, or whether a conviction may also be authorized if a victim attains the status of an individual after the alleged misconduct." Id., at 137. In concluding that the law authorized Cuellar's conviction, the court relied on the born alive rule and the fact that the courts of other states consistently have applied the rule in affirming convictions under similar statutes and factual scenarios. Id., at 137-39. The court explained that, "[i]t is not necessary that all of the elements of a criminal offense be immediately satisfied at the time of the defendant's conduct. It is axiomatic that a homicide conviction, requiring the death of the victim as an element of the offense, may stand even though the victim's death is not instantaneous with the defendant's conduct but results from that conduct at a later time.... To limit our perspective to the moment of the accused's conduct, as [Cuellar] urges, would be contrary to this well-established doctrine." (Citation omitted.) Id., at 139; see also State v. Cotton, supra, 197 Ariz. at 588-89, 5 P.3d 918 ("That the shooting in this case occurred while the infant was in utero does not preclude her post-birth status as a `person' for purposes of Arizona's homicide statutes. While the homicide statutes require that the victim be a `person,' they do not limit the nature or timing of the injury that causes the death of the `person.' Additionally, the statutes do not require that all the elements of the offenses be immediately satisfied at the time of the defendant's conduct."); State v. Hammett, 192 Ga.App. 224, 225, 384 S.E.2d 220 (1989) ("[A] person who injures a pregnant woman so that her fetus, though born alive, subsequently dies by reason of the injuries inflicted on it while still in its mother's uterus, can be convicted for the felony murder of the newborn child.... It is thus apparent that it is not the victim's status at the time the injuries are inflicted that determines the nature of the crime ... but [rather] the victim's status at the time of death which is the determinative factor." [Citations omitted.]); Jones v. Commonwealth, supra, 830 S.W.2d at 880 ("[m]urder and manslaughter are criminal acts that result in the death of a `person' ... and neither the common law nor our statutes [require] `person' status at the time the act occurred" [citations omitted]). We agree generally with the reasoning of the foregoing cases.

We note, finally, that, under the doctrine of legislative acquiescence, we may infer that the failure of the legislature to take corrective action within a reasonable period of time following a definitive judicial interpretation of a statute signals legislative agreement with that interpretation. See, e.g., Mahon v. B.V. Unitron Mfg., Inc., 284 Conn. 645, 665-66, 935 A.2d 1004 (2007). "Although we are aware that legislative inaction is not necessarily legislative affirmation ... we also presume that the legislature is aware of [this court's] interpretation of a statute, and that its subsequent nonaction may be understood as a validation of that interpretation." (Internal quotation marks omitted.) Id., at 665, 935 A.2d 1004. Under this court's recent decision in State v. Fernando A., 294 Conn. 1, 20 n. 15, 981 A.2d 427 (2009), we also are free to apply the doctrine to *67 officially published decisions of the Superior Court. Fernando A. is relevant to the present case because the born alive rule has been recognized in two published Superior Court decisions, namely, State v. Anonymous (1986-1), supra, 40 Conn. Supp. at 498, 516 A.2d 156, which was decided more than twenty years ago, and State v. Courchesne, supra, 46 Conn.Supp. at 63, 757 A.2d 699, which was decided more than ten years ago. Thus, under Fernando A., we would be permitted to presume that the failure of the legislature to abrogate the born alive rule by amending our Penal Code constitutes legislative approval of the rule. We need not rely on the presumption available to us under Fernando A., however, in light of the legislative history and genealogy of P.A. 03-21 because, as we previously explained, that history and genealogy demonstrates, first, that the legislature was aware of both Anonymous and Courchesne when it enacted P.A. 03-21, and, second, that it enacted P.A. 03-21 with a full appreciation that, although that provision protects only those fetuses that are injured and die in utero, our murder statute, ง 53a-54a, embodies the born alive rule and, therefore, protects those infants who are injured in utero but who nevertheless are born alive and do not die until after birth.^[68]

In sum, the born alive rule is well established in the common law of this state, and P.A. 03-21 reflects the legislature's express acceptance of the rule. Moreover, there is nothing in our homicide statutes or elsewhere in the Penal Code to suggest that application of the rule is barred by any requirement of a temporal nexus between the defendant's conduct and the status of the victim.

*68 III

TRANSFERRED INTENT UNDER ง 53a-54a(a)

We next address the defendant's related contention that the trial court misapplied the doctrine of transferred intent by permitting the state to rely on that legal principle in establishing that the defendant had murdered Antonia. Specifically, the defendant asserts that his intent to kill Rodgers could not be transferred to Antonia because, at the time he assaulted and killed Rodgers, Antonia was not yet a person within the meaning of ง 53a-54a(a). According to the defendant, the transferred intent principle "has never been applied to situations in which the defendant's intent to kill a person is transferred to another entity that had not legally attained the status of a `person' at the time the defendant acted." Our recognition of the applicability of the born alive rule to the law of homicide also is dispositive of the defendant's transferred intent claim.

The doctrine of transferred intent operates to render a defendant culpable of the murder of a third person when the defendant causes the death of that third person with the intent to cause the death of someone else. See, e.g., State v. Higgins, 265 Conn. 35, 51-52, 826 A.2d 1126 (2003); State v. Henry, supra, 253 Conn. at 359, 752 A.2d 40. The principle, which is reflected in the express language of ง 53a-54a(a), represents a policy determination by the legislature that a defendant who engages in such conduct is no less culpable than if he had killed his intended victim.

As we previously explained, under the born alive rule, a person who inflicts injuries on a fetus in utero with the intent to kill that fetus is guilty of murder if the fetus is born alive but subsequently dies as a result of the injuries suffered in utero. Consequently, the born alive rule operates to render the fetus a person for purposes of our homicide statutes if that fetus, having been injured in utero, nevertheless is born alive and then dies of the injuries sustained in utero. Put differently, in that particular factual scenario, the fetus is treated like any other person. Thus, a defendant who, intending to kill a pregnant woman, inflicts injuries on the fetus that prove to be fatal only after the fetus is born alive, that is, once the fetus has achieved the status of a person under the born alive rule, is guilty of murder by operation of the transferred intent doctrine embodied in ง 53a-54a(a). In other words, because a fetus that is born alive is a person for purposes of our homicide statutes, the transferred intent provisions of ง 53a-54a(a) are equally applicable to a fetus that is born alive as they are to any other person.

The defendant has provided no persuasive reason why these two principles, each of which represents the public policy of this state as determined by the legislature, should not be applied in tandem for purposes of interpreting our statutory scheme. In the absence of any such reason, we reject his claim that the transferred intent provisions of ง 53a-54a(a) are inapplicable to the present case.^[69]

*69 IV

DUE PROCESS AND EX POST FACTO CLAIMS

The defendant next claims that the application of the born alive rule to his conduct, rather than prospective application only, violates his right to fair notice under the due process and ex post facto clauses of the United States constitution. See footnote 29 of this opinion. He further contends that the court's "novel integration" of the born alive rule and the doctrine of transferred intent "created an unconstitutionally vague theory of murder as applied to [his] conduct...." In other words, the defendant contends that a reasonable person in his position, at the time he assaulted Rodgers, could not be presumed to have known that his actions violated the murder and capital felony statutes with respect to Antonia. We also disagree with these claims.

"The basic principle that a criminal statute must give fair warning of the conduct that it makes a crime has often been recognized by [the United States Supreme] Court." Bouie v. Columbia, 378 U.S. 347, 350-51, 84 S.Ct. 1697, 12 L.Ed.2d 894 (1964). "The constitutional requirement of definiteness is violated by a criminal statute that fails to give a person of ordinary intelligence fair notice that his contemplated conduct is forbidden by the statute. The underlying principle is that no man shall be held criminally responsible for conduct which he could not reasonably understand to be proscribed." United States v. Harriss, 347 U.S. 612, 617, 74 S.Ct. 808, 98 L.Ed. 989 (1954). "It is settled that the fair-warning requirement embodied in the [d]ue [p]rocess [c]lause prohibits the [s]tates from holding an individual criminally responsible for conduct which he could not reasonably understand to be proscribed." (Internal quotation marks omitted.) Rose v. Locke, 423 U.S. 48, 49, 96 S.Ct. 243, 46 L.Ed.2d 185 (1975).

"There are three related manifestations of the fair warning requirement. First, the vagueness doctrine bars enforcement of a statute which either forbids or requires the doing of an act in terms so vague that men of common intelligence must necessarily guess at its meaning and differ as to its application.^[70] ... Second ... the canon of strict construction of criminal statutes, or rule of lenity, ensures fair warning by so resolving ambiguity in a criminal statute as to apply it only to conduct clearly covered.^[71] ... United *70 States v. Lanier, 520 U.S. 259, 266, 117 S.Ct. 1219, 137 L.Ed.2d 432 (1997). Third, [t]here can be no doubt that a deprivation of the right of fair warning can result ... also from an unforeseeable and retroactive judicial expansion of narrow and precise statutory language. Bouie v. Columbia, supra, 378 U.S. [at] 352 [84 S.Ct. 1697]. In each of these guises, the touchstone is whether the statute, either standing alone or as construed, made it reasonably clear at the relevant time that the defendant's conduct was criminal. United States v. Lanier, supra, [at] 267 [117 S.Ct. 1219]." (Internal quotation marks omitted.) State v. Miranda, supra, 260 Conn. at 103, 794 A.2d 506.

The defendant invokes what is best described as a combination of the first and third of these manifestations of the fair warning doctrine in challenging the constitutionality of the born alive rule as applied to the present case.^[72] In Rogers v. Tennessee, supra, 532 U.S. at 451, 121 S.Ct. 1693, the United States Supreme Court addressed those aspects of the fair warning requirement and, in so doing, reaffirmed the approach that it previously had articulated in Bouie v. Columbia, supra, 378 U.S. at 347, 84 S.Ct. 1697, explaining: "Reviewing decisions in which we had held criminal statutes void for vagueness under the [d]ue [p]rocess [c]lause, we noted [in Bouie] that this [c]ourt has often recognized the basic principle that a criminal statute must give fair warning of the conduct that it makes a crime.... Deprivation of the right to fair warning ... can result both from vague statutory language and from an unforeseeable and retroactive judicial expansion of statutory language that appears narrow and precise on its face.... For that reason ... [i]f a judicial construction of a criminal statute is unexpected and indefensible by reference to the law which had been expressed prior to the conduct in issue, [the construction] must not be given retroactive effect."^[73] (Citations *71 omitted; internal quotation marks omitted.) Rogers v. Tennessee, supra, at 457, 121 S.Ct. 1693.

In essence, therefore, the due process clause "requires only that the law give sufficient warning that men may conduct themselves so as to avoid that which is forbidden, and thus not lull the potential defendant into a false sense of security, giving him no reason even to suspect that his conduct might be within its scope." (Internal quotation marks omitted.) Rubin v. Garvin, 544 F.3d 461, 469 (2d Cir.2008). "Furthermore, the unavoidable ambiguities of language do not transform every circumstance in which judicial construction is necessary into a violation of the fair notice requirement: `The root of the vagueness doctrine is a rough idea of fairness. It is not a principle designed to convert into a constitutional dilemma the practical difficulties in drawing criminal statutes both general enough to take into account a variety of human conduct and sufficiently specific to provide fair warning that certain kinds of conduct are prohibited.' Colten v. Kentucky, 407 U.S. 104, 110, 92 S.Ct. 1953, 32 L.Ed.2d 584 (1972)...." (Citations omitted.) Ortiz v. N.Y.S. Parole in Bronx, N.Y., 586 F.3d 149, 159 (2d Cir.2009). In other words, "[d]ue process does not require statutes to provide a laundry list of prohibited conduct. [L]aws may be general in nature so as to include a wide range of prohibited conduct. The constitution requires no more than a reasonable degree of certainty." (Internal quotation marks omitted.) State v. Wilchinski, 242 Conn. 211, 224, 700 A.2d 1 (1997). Moreover, "[d]ue process is not ... violated simply because the issue is a matter of first impression." (Internal quotation marks omitted.) Ortiz v. N.Y.S. Parole in Bronx, N.Y., supra, at 159. Thus, the retroactive application of a judicial decision will be deemed to represent "an exercise of the sort of unfair and arbitrary judicial action against which the [d]ue [p]rocess [c]lause aims to protect" only if that decision constitutes "a marked and unpredictable departure from prior precedent...." Rogers v. Tennessee, supra, 532 U.S. at 467, 121 S.Ct. 1693.

Subsequent to Rogers, this court, in State v. Miranda, supra, 260 Conn. at 93, 794 A.2d 506, observed that the fair warning principles articulated in Rogers and Bouie are "in accordance with our fair warning jurisprudence. We consistently have held that [w]hile we also recognize that criminal statutes are to be construed strictly, the language in a criminal statute need not be given its narrowest possible construction.... A statute is not unconstitutional merely because a person must inquire further as to the precise reach of its prohibitions.... In addition, [r]eferences to judicial opinions involving the statute, the common law, legal dictionaries, or treatises may be necessary to ascertain a statute's meaning to determine if it gives fair warning.... We [also] can use as a guide judicial opinions that, [although] not binding on this court, refer to the statute in question or to a statute that uses similar language." (Citations omitted; *72 internal quotation marks omitted.) Id., at 105-106, 794 A.2d 506; see also Rose v. Locke, supra, 423 U.S. at 50, 52, 96 S.Ct. 243 (court considered judicial interpretations of similar state statutes in rejecting claim that Tennessee sodomy statute prohibiting "`crimes against nature'" was unconstitutionally vague).

Furthermore, because this court routinely relies on settled principles of statutory interpretation to ascertain the meaning of an ambiguous statute, our reasoned application of those ordinary tools of construction no doubt will result in an interpretation of the statute at issue that is both foreseeable and defensible for purposes of due process. See State v. Miranda, supra, 260 Conn. at 109, 794 A.2d 506 ("To reach the conclusion that we did, we relied on ordinary tools of statutory construction. Those tools of statutory construction demonstrated that by reference to the law as it then existed, it was neither unexpected nor indefensible to [interpret the statute in the manner that we did].") This same standard applies to the defendant's closely related vagueness claim. In view of the fact that a statute is not unconstitutional merely because it is ambiguous or requires further investigation, the defendant can prevail on his claim under the vagueness doctrine only if he can demonstrate that the statutory meaning cannot be fairly ascertained upon application of established principles of statutory interpretation. See, e.g., State v. Ehlers, 252 Conn. 579, 591, 750 A.2d 1079 (2000) ("[i]f the meaning of a statute can fairly be ascertained through judicial construction... it need not be stricken for vagueness" [internal quotation marks omitted]). In other words, a statute that is not clear on its face will survive a vagueness challenge if its meaning can be discerned by use of ordinary tools of statutory construction. See id. Finally, as we previously have noted, "to prevail on [a vagueness] claim, [a] defendant must demonstrate beyond a reasonable doubt that the statute, as applied to him, deprived him of adequate notice of what conduct the statute proscribed...." (Internal quotation marks omitted.) State v. Knybel, 281 Conn. 707, 714, 916 A.2d 816 (2007).

Our inquiry under the ex post facto clause proceeds along similar lines. "The ex post facto prohibition forbids ... the [s]tates [from] enact[ing] any law [that] imposes a punishment for an act [that] was not punishable at the time it was committed ... or imposes additional punishment to that then prescribed.... Through this prohibition, the [f]ramers sought to assure that legislative [a]cts give fair warning of their effect and permit individuals to rely on their meaning until explicitly changed.... Weaver v. Graham, 450 U.S. 24, 28-29, 101 S.Ct. 960, 67 L.Ed.2d 17 (1981). [T]wo critical elements must be present for a criminal or penal law to be ex post facto: it must be retrospective, that is, it must apply to events occurring before its enactment, and it must disadvantage the offender affected by it. Id., [at] 29 [101 S.Ct. 960]." (Internal quotation marks omitted.) Washington v. Commissioner of Correction, 287 Conn. 792, 805, 950 A.2d 1220 (2008).

We have recognized that the judicial construction of a statute can operate like an ex post facto law and thus violate a criminal defendant's right to fair warning as to what conduct is prohibited. See, e.g., Johnson v. Commissioner of Correction, 288 Conn. 53, 58-59 n. 4, 951 A.2d 520 (2008). "The United States Supreme Court has observed, [a]s the text of the [ex post facto] [c]lause makes clear, it is a limitation [on] the powers of the [l]egislature, and does not of its own force apply to the [j]udicial [b]ranch of government.... Rogers v. Tennessee, [supra, 532 U.S. at *73 456, 121 S.Ct. 1693]. Nevertheless, limitations on ex post facto judicial decisionmaking are inherent in the notion of due process. Id. In Bouie v. Columbia, [supra, 378 U.S. at 347, 84 S.Ct. 1697], the United States Supreme Court observed: If a state legislature is barred by the [e]x [p]ost [f]acto [c]lause from passing such a law, it must follow that a [s]tate Supreme Court is barred by the [d]ue [p]rocess [c]lause from achieving precisely the same result by judicial construction.... If a judicial construction of a criminal statute is unexpected and indefensible by reference to the law which had been expressed prior to the conduct in issue, it must not be given retroactive effect.... Id., [at] 353-54 [84 S.Ct. 1697]; see also State v. Hart, 221 Conn. 595, 612-13 n. 15, 605 A.2d 1366 (1992)." (Internal quotation marks omitted.) Washington v. Commissioner of Correction, supra, 287 Conn. at 805-806, 950 A.2d 1220.

"[A] judicial construction of a statute is an authoritative statement of what the statute meant before as well as after the decision of the case giving rise to that construction.... Rivers v. Roadway Express, Inc., 511 U.S. 298, 312-13, 114 S.Ct. 1510, 128 L.Ed.2d 274 (1994). [Thus], when [a] court construes a statute, it is explaining its understanding of what the statute has meant continuously since the date when it became law. Id., [at] 313 n. 12 [114 S.Ct. 1510]." Washington v. Commissioner of Correction, supra, 287 Conn. at 810-11, 950 A.2d 1220. In determining whether a judicial construction of a statute effectively operates as a prohibited ex post facto law, "[t]he question ... is whether [the] decision was so unforeseeable that [the defendant] had no fair warning that it might come out the way it did." (Internal quotation marks omitted.) Id., at 809, 950 A.2d 1220. Put differently, "[t]he key test in determining whether the due process clause precludes the retrospective application of a judicial decision... is whether the decision was sufficiently foreseeable so that the defendant had fair warning that the interpretation given the relevant statute by the court would be applied in his case." Aue v. Diesslin, 798 P.2d 436, 441 (Colo.1990).

Applying these principles to the present case, we find no merit to the defendant's first contention that he lacked fair notice that his actions violated the murder and capital felony statutes with respect to Antonia. Our previous analysis leading to the rejection of the defendant's claim concerning the inapplicability of the born alive rule and, in particular, our reasons for concluding that the term "person," as used in this state's murder statute, includes an infant who suffers injuries in utero, is born alive and subsequently dies from those injuries, necessarily are fatal to the defendant's due process and ex post facto claims. See State v. Winot, 294 Conn. 753, 759, 988 A.2d 188 (2010) (criminal statute not void for vagueness if its meaning can be discerned by resort to extratextual sources and tools of construction); Washington v. Commissioner of Correction, supra, 287 Conn. at 803-804, 810-11, 950 A.2d 1220 (retroactive application of judicial interpretation of statute did not operate as functional equivalent of ex post facto law and violate due process when interpretation was based on reasoned application of tools of construction and thus could not be considered unforeseeable and indefensible); State v. Miranda, supra, 260 Conn. at 109-10, 794 A.2d 506 (in concluding that fair notice component of due process was not violated by retroactive application of judicial construction of criminal statute, court observed that construction had been reached by resort to ordinary tools of statutory construction). In light of the fact that the *74 born alive rule has been embodied in our Penal Code since the code's adoption nearly four decades ago, our recognition of the rule reasonably cannot be characterized as a departure from settled law, let alone a radical and unforeseeable change in the law.

In his concurring and dissenting opinion, Justice Schaller nevertheless asserts that our recognition of the born alive rule violates due process, apparently because, in his view, doing so represents an unexpected and indefensible interpretation of the law as it existed when the defendant killed Rodgers and Antonia.^[74] Justice Schaller's assertions notwithstanding, our analytical approach and conclusion is entirely consistent with, and is dictated by, the analysis and holdings of two seminal and controlling cases in this area, namely, Rogers v. Tennessee, supra, 532 U.S. at 451, 121 S.Ct. 1693, and State v. Miranda, supra, 260 Conn. at 93, 794 A.2d 506.^[75] In these cases, the United States Supreme Court and this court, respectively, rejected the same essential due process claim that the defendant raises in the present case, but in both Rogers and Miranda, the statutory construction that each court upheld as consistent with the fair notice requirement was far less predictable and foreseeable than our construction of ง 53a-54a as incorporating the born alive rule. We therefore reject as contrary to settled lawโ€”and to the commonsense principles that underlie that lawโ€”Justice Schaller's assertion that only if the defendant was "clairvoyan[t]" when he launched his vicious and lethal attack on Rodgers and Antonia could he have been expected to understand the criminal consequences of his conduct.

In Rogers, the petitioner, Wilbert K. Rogers, was convicted of second degree murder in Tennessee state court for the stabbing death of the victim. Rogers v. Tennessee, supra, 532 U.S. at 454, 121 *75 S.Ct. 1693. The victim, who had suffered life threatening injuries to his heart, survived for approximately fifteen months, after which he died from those injuries. Id. On appeal to the Supreme Court of Tennessee, Rogers claimed that Tennessee's common-law year and a day rule, pursuant to which a defendant cannot be convicted of murder unless the victim has died as a result of the defendant's conduct within one year and one day of that conduct, precluded his conviction for the murder of the victim. State v. Rogers, 992 S.W.2d 393, 394 (Tenn.1999). Although the Tennessee statutes did not expressly refer to the year and a day rule, the Supreme Court of Tennessee acknowledged that it had recognized the viability of the rule in 1907, and both parties agreed that the rule was part of the state's common law. See id., at 396, 399. After observing that the rule had been legislatively or judicially abolished in most jurisdictions and that the original justifications for the rule no longer existed, the court abolished the rule. Id., at 398, 401. The court affirmed Rogers' conviction, concluding that it did not offend principles of due process to apply its holding abolishing the year and a day rule to Rogers' case. Id., at 401-403.

The United States Supreme Court affirmed the judgment of the Supreme Court of Tennessee; Rogers v. Tennessee, supra, 532 U.S. at 467, 121 S.Ct. 1693; stating that "[t]here is ... nothing to indicate that the Tennessee's court abolition of the rule in [Rogers'] case represented an exercise of the sort of unfair and arbitrary judicial action against which the [d]ue [p]rocess [c]lause aims to protect. Far from a marked and unpredictable departure from prior precedent, the court's decision was a routine exercise of common law decisionmaking in which the court brought the law into conformity with reason and common sense. It did so by laying to rest the archaic and outdated rule that had never been relied [on] as a ground of decision in any reported Tennessee case." Id., at 466-67, 121 S.Ct. 1693. The court in Rogers reiterated that Bouie "restricted due process limitations on the retroactive application of judicial interpretations of criminal statutes to those that are `unexpected and indefensible by reference to the law which had been expressed prior to the conduct at issue.'" Id., at 461, 121 S.Ct. 1693, quoting Bouie v. Columbia, supra, 378 U.S. at 354, 84 S.Ct. 1697.

In Miranda, the defendant, Santos Miranda, who was twenty-one years old, resided with his sixteen year old girlfriend and her two year old son and four month old daughter. State v. Miranda, supra, 260 Conn. at 97, 794 A.2d 506. Although Miranda was not the biological father of either child, he took care of them and considered himself to be their stepfather. Id. Several months after Miranda had started living with his girlfriend, her four month old daughter was taken to the hospital, where it was determined that she previously had sustained a number of serious and apparently unrelated injuries, including multiple rib fractures that were approximately two to three weeks old, two skull fractures that were approximately seven to ten days old, an injury to her left arm, a rectal tear that was bleeding, and nasal hemorrhages. Id. Even though the state did not contend that Miranda himself had caused the injuries to the four month old child, he was arrested and charged with risk of injury to a child and multiple counts of assault in the first degree. Id., at 96-97, 99 and n. 4, 794 A.2d 506. Following a court trial, the "court concluded that [Miranda] had a legal duty to protect the health and well-being of the child based on the undisputed facts that he had established a familial relationship with the child's mother and her two children, that he had voluntarily assumed responsibility *76 for the care and welfare of both children, and that he considered himself [to be] the [child's] stepfather." Id., at 99, 794 A.2d 506. The trial court also found that, in light of the nature and extent of the child's injuries and in view of the fact that the child resided with Miranda, he necessarily was aware that there existed a substantial and unjustifiable risk that the child would be exposed to conduct that created a risk of death, and that, despite this knowledge, he had failed to help the child. Id., at 98, 794 A.2d 506. On the basis of these circumstances, the trial court found Miranda guilty of one count of risk of injury to a child and six counts of assault in the first degree. Id., at 99, 794 A.2d 506.

On appeal, the Appellate Court affirmed Miranda's conviction for risk of injury to a child but reversed his assault convictions, concluding that he had no legal duty to act under the circumstances. State v. Miranda, 41 Conn.App. 333, 341, 675 A.2d 925 (1996). We granted the state's petition for certification to appeal and "concluded that, [on the basis of] the trial court's findings that [Miranda] had established a familial relationship with the [child's] mother and [the] two children, had assumed responsibility for the welfare of the children, and had taken care of them as though he were their father, [Miranda] had assumed a legal duty to protect the [child] from abuse." State v. Miranda, supra, 260 Conn. at 99, 794 A.2d 506; see State v. Miranda, supra, 245 Conn. at 226, 230, 715 A.2d 680. We therefore reversed the judgment of the Appellate Court in part and remanded the case to that court for consideration of Miranda's evidentiary insufficiency claims and any constitutional claims of due process and double jeopardy arising as a result of this court's decision. State v. Miranda, supra, 260 Conn. at 100, 794 A.2d 506; see State v. Miranda, supra, 245 Conn. at 231, 715 A.2d 680.

On remand, the Appellate Court affirmed Miranda's conviction for risk of injury to a child. See State v. Miranda, 56 Conn.App. 298, 313, 742 A.2d 1276 (2000). With respect to Miranda's assault convictions, however, the Appellate Court concluded that convicting him of assault in the first degree would be a violation of due process because a person of ordinary intelligence in his circumstances would not have known that he had a duty to protect the child. Id., at 305-306, 308, 742 A.2d 1276. The Appellate Court therefore reversed the judgment of conviction with respect to the assault counts and remanded the case with direction to render judgment of not guilty with respect to those counts. Id., at 313-14, 742 A.2d 1276.

Following our granting of certification, and in reliance on the then recent opinion of the United States Supreme Court in Rogers, we concluded that the Appellate Court improperly had determined that Miranda's assault convictions deprived him of due process of law.^[76]State v. Miranda, supra, 260 Conn. at 100-101, 109-10, 794 A.2d 506. In particular, we concluded that our determination that the first degree assault statute applied to the facts of Miranda's case was reasonably foreseeable, such that a person of ordinary intelligence in Miranda's position should have anticipated that this court would find that he had a common-law duty to help the *77 child in this case and that his violation of that duty subjected him to conviction under the first degree assault statute. Id., at 109-10, 794 A.2d 506. In reaching this conclusion, we explained that, in recognizing the common-law duty to act under the facts of the case and in construing our assault statute to encompass Miranda's failure to act, we had employed ordinary tools of statutory construction, which included an examination of the plain language of our first degree assault statute, the language of other Connecticut statutes governing similar conduct, the common law of this state and other jurisdictions, and treatises addressing the issue.^[77] Id., at 106-109, 794 A.2d 506.

As we have indicated, it is readily apparent that the holdings in Rogers and Miranda represented a relatively broad and sweeping modification of then existing law, whereas our holding in the present case merely reflects our recognition and application of a well established common-law doctrine in accordance with settled principles of statutory construction. Indeed, in Rogers, the United States Supreme Court concluded that the Tennessee Supreme Court's abolition of the common-law year and a day rule could be applied retroactively to a defendant whose conduct occurred before the court's repudiation of that common-law rule. Under Rogers, therefore, the fair notice requirement is not necessarily violated even when a state's highest court reverses course completely with respect to an existing rule or interpretation and applies that change in the law retroactively to conduct that occurred prior thereto. In contrast to Rogers, the present case "does not involve any expansion of the scope of criminal liability beyond that indicated by previous decisional law." Ortiz v. N.Y.S. Parole in Bronx, N.Y., supra, 586 F.3d at 158. In other words, unlike in Rogers, we have not reversed prior precedent resulting in criminal liability where none previously had existed. In fact, no court of this state has ever even suggested that the born alive rule is inapplicable to our murder statute; on the contrary, as we have explained, the common-law roots of the rule, both in this state and elsewhere, are well established.

Moreover, in light of the holding of the United States Supreme Court in Rogers, even if the born alive rule previously had not been recognized in this state, our decision to do so today would constitute nothing more than a clarification or illumination of our murder statute as applied to the facts of this case, based on our considered view of what the legislature likely intended. In such circumstances, the conclusion of the court in Rogers concerning the Tennessee Supreme Court's repudiation of the year and a day rule would be equally applicable to our recognition of the born alive rule: "Far from a marked and unpredictable departure from prior precedent, the court's decision was a routine exercise of common law decisionmaking in which the court brought the law into conformity with reason and common sense." Rogers v. Tennessee, supra, 532 U.S. at 467, 121 S.Ct. 1693. Thus, even in the absence of evidence of the born alive rule in this state's common-law history, our decision to adopt the rule could not possibly be characterized as "unexpected and indefensible by reference to the law which had *78 been expressed prior to the conduct in issue." (Internal quotation marks omitted.) Id., at 462, 121 S.Ct. 1693.

Our holding in Miranda also represents a significantly less foreseeable or predictable application of the common law to a statutory provision than our application of the born alive rule in the present case. In fact, the Appellate Court originally concluded in Miranda that applying the assault statute to Miranda's passive conduct was unjustifiable because Miranda had no legal duty to act under the circumstances. See State v. Miranda, supra, 41 Conn.App. at 339-40, 675 A.2d 925. Moreover, when we concluded otherwise; State v. Miranda, supra, 245 Conn. at 230, 715 A.2d 680; the Appellate Court, on remand, determined that our decision was so unexpected and unforeseeable that it violated Miranda's right to fair notice to apply the decision to his case. See State v. Miranda, supra, 56 Conn.App. at 305-308, 742 A.2d 1276. Notwithstanding this court's subsequent contrary determination; State v. Miranda, supra, 260 Conn. at 109-10, 794 A.2d 506; we thereafter concluded that our original interpretation of the assault statute as encompassing a nonparent's failure to come to the aid of a child with whom he has a parent-like relationship was "clearly wrong"; State v. Miranda, supra, 274 Conn. at 734, 878 A.2d 1118; because it represented an unwarranted expansion of the assault statute. See id., at 733-34, 878 A.2d 1118; see also id., at 749, 878 A.2d 1118 (Borden, J., concurring) (rejecting this court's previous interpretation of assault statute as representing "unwise ... extension" of that statute resulting in provision with unacceptably "amorphous" boundaries); id., at 762, 878 A.2d 1118 (Vertefeuille, J., concurring) (concluding that assault statute "should not be extended by implication to encompass [Miranda's] failure to act"). Nevertheless, as we explained, this court previously had determined that our use of ordinary tools of statutory construction had led to a foreseeable interpretation of the assault statute, such that Miranda had fair notice that even his failure to act could constitute an assault. State v. Miranda, supra, 260 Conn. at 109-10, 794 A.2d 506.

Simply put, it is not possible to abide by the fair notice principles articulated and applied by the United States Supreme Court in Rogers and by this court in Mirandaโ€”cases that represent binding precedentโ€”and also to conclude that our recognition of the born alive rule in the present case violates those principles. Because neither Rogers nor Miranda represented a marked or unforeseeable departure from then applicable law, the present case, which represents a considerably more conventional and foreseeable example of common-law adjudication, certainly cannot be deemed to run afoul of due process requirements. For this reason, the due process analysis in Justice Schaller's concurring and dissenting opinion is flawed.^[78]

*79 Justice Schaller's analysis suffers from another fatal infirmity, namely, his assertion that the trial court incorrectly concluded that State v. Anonymous (1986-1), supra, 40 Conn.Supp. at 498, 516 A.2d 156, placed the defendant on notice of the born alive rule because the court's discussion of the rule in Anonymous was merely dictum.^[79] Contrary to Justice Schaller's contention, the court in Anonymous relied expressly on the born alive rule in concluding that a fetus killed in utero is not a person for purposes of our homicide statutes.^[80]

In Anonymous, the state had sought an arrest warrant in contemplation of charging the accused with the murder of a viable fetus in utero. Id. As the court in Anonymous stated, "[t]hat application require[d][the] court to decide whether an unborn but viable fetus is a `human being' within the meaning of the Connecticut statutes defining murder." Id. In concluding that it did not, the court observed, first, "that the codes from which our Connecticut law was drawn [namely, the New York Penal Law and the Model Penal Code] limit the words `human being' to those who have been born alive...." Id., at 501, 516 A.2d 156. The court further observed that the fact that these two bodies of law have adopted the born alive standard "supports the position that Connecticut's legislature did not intend to define a `human being' as an unborn but viable fetus." Id.

The court thereafter turned to the common law and, after noting that "[our] legislature, in enacting the murder statute, [presumably] was familiar with the general rules of common law on [the] subject when it enacted ... [our] [P]enal [C]ode"; id., at 502, 516 A.2d 156; explained that, as a principle of statutory construction, "[a] statute should not be construed as altering the common law rule, farther than the words of the statute import, and should not be construed as making any innovation [on] the common law which the statute does not fairly express." (Internal quotation marks omitted.) Id., quoting State v. Kish, 186 Conn. 757, 764, 443 A.2d 1274 (1982). The court, citing to Sir Edward Coke, explained that "it is well settled that the common law, as far back as 1648... held that an unborn fetus, viable or otherwise, could not be the subject of [a] homicide." (Citation omitted.) State v. Anonymous (1986-1), supra, 40 Conn. Supp. at 502, 516 A.2d 156. The court then cited nine cases in support of its assertion that "almost every state court that has had a homicide statute, similar to Connecticut's, that did not define `human *80 being' explicitly to include a fetus [has] held [that] the words `person' or `human being' would not include the unborn child or fetus." Id., at 503, 516 A.2d 156. The courts in each and every one of the cases cited by the court in Anonymous expressly relied on the born alive rule in rejecting a claim that a homicide prosecution could lie for the killing of a fetus that died in utero.<sup>[81]</sup> The court also acknowledged that two other sister state courts, each operating in a jurisdiction with common-law crimes, that is, "the legislature in [those] states merely codified existing criminal common law by prescribing penalties for existing common law crime," had "recognized that the preexisting common law did not recognize the killing of an unborn child as `homicide,' but felt that they had the authority to change the law prospectively" and to treat an unborn child as a person. Id., citing Commonwealth v. Cass, supra, 392 Mass. at 799, 467 N.E.2d 1324, and State v. Horne, supra, 282 S.C. at 444, 319 S.E.2d 703. These two courts, which then represented the distinct minority view, expressly had abrogated the born alive rule in favor of including a fetus within the class of potential victims protected under the homicide statutes of those states. See Commonwealth v. Cass, supra, at 807, 467 N.E.2d 1324; State v. Horne, supra, at 447, 319 S.E.2d 703.

The court in Anonymous then considered the possible due process consequences of applying retroactively "a new interpretation" of our murder statute that would include within its purview a viable fetus. State v. Anonymous (1986-1), supra, 40 Conn.Supp. at 503-504, 516 A.2d 156. Turning to Cass and Horne, the court explained that even those courts "have agreed with majority jurisdictions that to apply a new interpretation of the words `human being' retroactively to include a viable but unborn fetus would violate constitutional principles that prohibit retroactive criminal laws." Id.; see Commonwealth v. Cass, supra, 392 Mass. at 807-808, 467 N.E.2d 1324; State v. Horne, supra, 282 S.C. at 447, 319 S.E.2d 703. After quoting with approval from a third case, namely, Keeler v. Superior Court, 2 Cal.3d 619, 470 P.2d 617, 87 Cal.Rptr. 481 (1970), in which the Supreme Court of California had rejected the state's request to abolish the born alive rule and to expand the definition of "person" in the California homicide statutes to include a viable fetus; id., at 631, 470 P.2d 617, 87 Cal. Rptr. 481; the court in Anonymous stated that, "to charge the accused with the murder of the unborn but viable fetus would violate the accused's due process rights." State v. Anonymous (1986-1), supra, at 504, 516 A.2d 156.

Finally, the court in Anonymous observed that its decision to invoke the born alive rule applied "only to the crime of murder and not to tort law." Id., at 505, 516 A.2d 156. The court explained: "American courts [that] have extended the benefits of tort law to fetuses have also, in the absence of specifically inclusive language, uniformly refused to change the *81 born-alive rule in criminal cases .... The rationale is that [d]iffering objectives and considerations in tort and criminal law foster the development of different principles governing the same factual situation." (Citation omitted; emphasis added; internal quotation marks omitted.) Id. Thus, the court clarified that its rationale for applying the born alive rule for purposes of the criminal law was not applicable to tort law. The court thereafter denied the application for an arrest warrant. Id.

As the foregoing discussion clearly demonstrates, the court in Anonymous declined to expand the definition of the term "person" under our murder statute to include an unborn but viable fetus because of its predicate determination that the born alive rule had been incorporated into the statute, and that to abolish the rule in favor of a broader definition of "person" would be incompatible with an accused's due process right to fair notice. See id., at 503-504, 516 A.2d 156. Consequently, the court's recognition of the born alive rule in Anonymous was necessary to its conclusion and, therefore, part of its holding rather than dictum. See footnote 79 of this opinion. That the court's recognition of the born alive rule in Anonymous was a critical aspect of its holding is reflected by the fact that a multitude of courts and commentators have identified Anonymous as a case in which the court recognized and applied the born alive rule. See, e.g., Vo v. Superior Court, 172 Ariz. 195, 203, 836 P.2d 408 (App.1992); State v. Courchesne, supra, 46 Conn.Supp. at 72, 757 A.2d 699; State v. Lamy, supra, 158 N.H. at 517 and n. 3, 969 A.2d 451; State v. Beale, 324 N.C. 87, 92, 376 S.E.2d 1 (1989); Commonwealth v. Booth, supra, 564 Pa. at 238 n. 7, 766 A.2d 843; J. Brobst, "The Prospect of Enacting an Unborn Victims of Violence Act in North Carolina," 28 N.C. Cent. L.J. 127,135 (2006); M. Fleming, "Feticide Laws: Contemporary Legal Applications and Constitutional Inquiries," 29 Pace L.Rev. 43, 48 n. 27 (2008); T. Hartsoe, "Person or Thingโ€”In Search of the Legal Status of a Fetus: A Survey of North Carolina Law," 17 Campbell L.Rev. 169, 212 and n. 233 (1995); C. Ramsey, "Restructuring the Debate over Fetal Homicide Laws," 67 Ohio St. L.J. 721, 739 n. 84 (2006); M. Kime, note, "Hughes v. State: The `Born Alive' Rule Dies a Timely Death," 30 Tulsa L.J. 539, 543 and n. 39 (1995); C. Leventhal, comment, "The Crimes Against the Unborn Child Act: Recognizing Potential Human Life in Pennsylvania Criminal Law," 103 Dick. L.Rev. 173, 176 and n. 27 (1998); S. Locke, note, "Abortion Revived: Is the Fetus a Person? Can the Present Law Remain in Light of State v. Courchesne?," 23 T. Jefferson L.Rev. 291, 304 (2001).

Thus, as the court stated in State v. Courchesne, supra, 46 Conn.Supp. at 63, 757 A.2d 699, because Anonymous "expressly follow[ed] the common-law [born alive] rule"; id., at 71, 757 A.2d 699; the published decision in that case "can be considered to have actually given notice that the defendant's actions concerning Antonia constituted murder separate from that of her mother [Rodgers]."^[82] Id., at *82 72, 757 A.2d 699. This is especially true in light of our recent decision in State v. Fernando A., supra, 294 Conn. at 20 n. 15, 981 A.2d 427, which permits us to presume, first, that the legislature is aware of officially published decisions of the Superior Court and, second, that the legislature's failure to respond to such a decision reflects the legislature's acquiescence in it. If an officially published decision of the Superior Court is sufficiently important to give rise to an inference that the legislature will take action if it disagrees with that decision, then such a decision certainly is sufficient to place the public on notice, for due process purposes, of the legal principles articulated therein.^[83]

We also reject the defendant's claim that applying the born alive rule in combination with the doctrine of transferred intent violated his rights under the due process and ex post facto clauses. The born alive rule and the doctrine of transferred intent are well established. The born alive rule has deep roots in our common law, as we have explained, and our murder statute, namely, ง 53a-54a(a), expressly incorporates the transferred intent principle. We can think of no reason why the application of these two doctrines renders the defendant's conviction constitutionally infirm merely because the defendant's conduct implicated both doctrines and, consequently, together formed the basis of the defendant's culpability for the murder of Antonia. The application of these doctrines to the defendant was not unforeseeable, novel or otherwise unfair.

On the contrary, as one court has stated in addressing a similar contention: "[I]t is impossible to perceive how an individual of even less than ordinary intelligence can fail to be aware that [stabbing a pregnant woman repeatedly in the chest and back] is not lawful conduct, and, in fact, [the perpetrator's] behavior after the [stabbing] in immediately [fleeing and] divesting himself of the [knife] ... clearly indicates that he recognized the criminality involved in his actions....

"[I]t is simply ludicrous to suppose that a particular statute fails to provide fair notice of forbidden conduct if it does not expressly anticipate every possible criminal contingency.... [I]t is fatuous for [the *83 perpetrator] to complain that he did not receive fair notice that he was acting in a criminal manner [and could be held criminally liable if the pregnant woman's baby was born alive but subsequently died]." (Citation omitted.) People v. Hall, supra, 158 App.Div.2d at 79-80, 557 N.Y.S.2d 879; see also United States v. Spencer, supra, 839 F.2d at 1342-44 (rejecting claim that defendant could not have foreseen that kicking and stabbing pregnant woman in stomach could result in murder conviction for death of baby ten minutes after birth); State v. Cotton, supra, 197 Ariz. at 589-90, 5 P.3d 918 (application of homicide statutes to conduct that resulted in postpartum death of baby did not violate defendant's due process rights).

We acknowledge that, under our interpretation of the relevant statutory scheme, a person who assaults a pregnant woman and causes the death of the fetus in utero will be subject to a lesser sanction than a person who commits the same assault when the fetus is born alive and subsequently dies of injuries resulting from that assault.^[84] The defendant contends that such a result is arbitrary and unfair and creates a perverse incentive for criminals not to render aid to their dying victims, or to secrete their bodies to ensure that medical aid cannot be rendered to the fetus. In State v. Cotton, supra, 197 Ariz. at 590-91, 5 P.3d 918, the Court of Appeals of Arizona addressed and rejected this very argument, and we agree with that court's analysis and conclusion.

In Cotton, the defendant, Lawrence Cotton, was charged with two counts of second degree reckless murder after he accidentally shot and killed his girlfriend, who was eight and one-half months pregnant. Id., at 586, 5 P.3d 918. The baby was born alive but died one day after being born. Id. Cotton urged the Arizona Court of Appeals to extend its reasoning in Vo v. Superior Court, supra, 172 Ariz. at 195, 836 P.2d 408, in which the court had concluded that the definition of "person" under the Arizona first degree murder statute did not include a fetus. Id.; see State v. Cotton, supra, 197 Ariz. at 587, 5 P.3d 918. In Vo, the court "held that the trial court should have dismissed murder charges against the defendants for the death of a fetus that occurred after one of the defendants shot the pregnant mother"; State v. Cotton, supra, at 587, 5 P.3d 918; reasoning that, "in enacting the statute, the legislature had not expressed an intent to deviate from the common law principle that only persons `born alive' could be the victims of homicide." Id., citing Vo v. Superior Court, supra, at 200, 206, 836 P.2d 408. The court in Vo had "found support for [its] conclusion ... in the fetal manslaughter statute ... which, by defining the killing of an unborn child as a separate offense from the killing of a `person,' evidenced a legislative determination that a fetus was not to be considered a person within the meaning of the murder statute." (Citation omitted.) State v. Cotton, *84 supra, at 587, 5 P.3d 918, citing Vo v. Superior Court, supra, at 201, 836 P.2d 408.

Cotton nevertheless maintained that his case presented a scenario that was legally indistinguishable from Vo, and "that, if it was not murder for the ... defendants [in Vo] to cause the death of an unborn child, it similarly should not be murder or manslaughter for [Cotton] to have harmed a fetus who later died of her injuries after birth." State v. Cotton, supra, 197 Ariz. at 587, 5 P.3d 918. The court disagreed, noting that Cotton had "caused the death not of a fetus, but of a child who had been born." Id. The court also rejected Cotton's contention that Arizona's fetal manslaughter statute "reflect[ed] a legislative determination that the [s]tate's other homicide statutes should not apply to situations in which fatal injuries are inflicted on a fetus, even if death does not result until after the child is born." Id., at 588, 5 P.3d 918. The court explained: "By its terms, the fetal manslaughter statute applies only to the killing of an unborn child. It reflects a legislative decision to afford protection to unborn children that was not available under traditional homicide statutes because of the common law born alive rule.... Absent any legislative history to the contrary, we presume that the legislature's adoption of [the fetal manslaughter statute] merely reflects a desire to afford greater protection to the unborn fetus than was available under common law, not less protection to a child who, despite the homicidal conduct of another, happens to survive past birth." Id.

Finally, Cotton asserted that it was fundamentally unfair and against public policy "to permit a [murder] conviction ... for inflicting prenatal injuries if the child survives, but to allow a conviction only for fetal manslaughter if the child dies before birth." Id., at 590, 5 P.3d 918. Cotton maintained "that such an interpretation would discourage a perpetrator from attempting to save the life of an injured fetus." Id., at 590-91, 5 P.3d 918. Although the court acknowledged the "irony" inherent in the existing statutory scheme, it expressed doubt that "persons who have engaged in homicidal conduct will render aid to their victims, fetal or otherwise. Rarer still would be the killer who would refrain from attempting to save the life of the fetus solely based [on] the knowledge that allowing the child to die might reduce the perpetrator's culpability from murder to manslaughter." Id., at 591, 5 P.3d 918. The court concluded that, "[e]ven [if its interpretation of Arizona's] homicide statutes [as applying] when the injured fetus dies after birth would have the effect Cotton claims, a contrary interpretation would result in even greater injustice. One who recklessly kills a fetus before birth under circumstances that would constitute murder of the mother could be convicted of fetal manslaughter.... However, under Cotton's interpretation, one who premeditatedly injures a child in utero could not be prosecuted for the later death, [as] long as the child lived long enough to be born: the fetal manslaughter statute would not apply once the child was born and the murder statute would not apply because no injury was inflicted on a `person.' Thus, Cotton's interpretation would spawn the irony that the more serious criminal act of intentionally harming the fetus would carry no sanction if the child died after birth, while recklessly engaging in the same conduct would carry the possible sentence of ten and one-half years [imprisonment] if the fetus died before birth....

"It is inconceivable that [the Arizona] legislature would have intended that the perpetrator escape responsibility for the child's death in the former scenario, but not the latter. To the extent that Cotton is correct in arguing that the interplay *85 between the fetal manslaughter statute and the murder statutes has created a perverse incentive not to render aid to a dying fetus, his policy arguments are best addressed to the legislature, which is the appropriate forum for determining what, if any, reform is appropriate." (Citations omitted.) Id.

We agree with the reasoning of the court in Cotton. If we were to determine, consistent with the defendant's contention in the present case, that the definition of "person" under our murder and capital felony statutes does not include an infant who is born alive and later dies from injuries inflicted in utero, we also would be required to conclude that the legislature, through its enactment of P.A. 03-21, intended to punish an assault on a pregnant woman that causes the termination of her pregnancy that does not result in a live birth, on the one hand, but intended no punishment for the same conduct if the fetus happens to be born alive but dies shortly thereafter from its injuries, on the other hand. We will not assume that the legislature intended such an irrational and bizarre result, especially because the legislative history surrounding P.A. 03-21 definitively establishes a contrary legislative intent.^[85]

*86 Moreover, it is not fundamentally unfair for the legislature to treat the killing of a fetus in one manner and the killing of an infant who is born alive and subsequently dies of prenatal injuries in another manner. We are aware, of course, that the legislature's decision to treat a fetus that dies in utero differently than an infant who is born alive produces a particularly unfortunate result for the defendant in the present case because, under the applicable statutory scheme, if he were not criminally liable for the murder of Antonia, he would not be eligible to receive the death penalty. To adopt the contention of the defendant, however, that an infant who is born alive but later dies of injuries sustained in utero is not a person "would usurp the legislature's role and require this court to vitiate what is an inherently legislative determination.... The categorization of offenses is a legislative judgment, and, generally speaking, it is not the prerogative of courts in this area lightly to launch an inquiry to resolve a debate [that] has already been settled in the legislative forum.... We defer to the broad authority that legislatures possess in determining the types and limits of punishment for crimes. Indeed, [i]n examining the rationality of a legislative classification, we are bound to defer to the judgment of the legislature unless the classification is clearly irrational and unreasonable." (Citations omitted; internal quotation marks omitted.) State v. Heinemann, 282 Conn. 281, 310-11, 920 A.2d 278 (2007). Because it is not irrational for the legislature to treat a fetus that is injured and dies in utero differently from an infant who is born alive but who subsequently dies from injuries sustained in utero, and in view of the fact that the competing policy concerns were raised and fully debated at the legislative hearings on the bill that would have redefined the term "person" in the Penal Code to include a viable fetus, it would be improper for us to modify our statutory scheme in the manner that the defendant advocates.^[86]

*87 V

EVIDENTIARY SUFFICIENCY AND THE CORRECT LEGAL STANDARD FOR DETERMINING WHETHER ANTONIA WAS BORN ALIVE

The defendant next claims that, even if the panel properly concluded that the born alive rule is applicable to the present case, he nevertheless is entitled to a judgment of acquittal with respect to the murder and capital felony charges pertaining to the death of Antonia because the evidence was insufficient to establish beyond a reasonable doubt that Antonia was born alive under "prevailing Connecticut law defining what it means to be alive."^[87] (Internal quotation marks omitted.) Specifically, the defendant contends that the panel failed to apply the principles articulated by this court in State v. Guess, supra, 244 Conn. at 761, 715 A.2d 643. We agree with the defendant's contention that the panel improperly failed to apply the principles articulated in Guess because, at the time of trial, neither the parties nor the panel appreciated the relevance of those principles to the present case. Because the evidence was sufficient to support the defendant's conviction under the standard that the panel did apply, however, the defendant is not entitled to an acquittal, as he claims; rather, he is entitled to a new trial. Cf. State v. DeJesus, 288 Conn. 418, 434, 438-39, 953 A.2d 45 (2008) (state entitled to retry defendant when trial court instructed jury using incorrect legal standard based on subsequent clarification in law, and evidence adduced at original trial was sufficient to meet that standard).

We commence our review of the defendant's claim with a summary of our analysis and holding in Guess. In Guess, the defendant, Barry Guess, repeatedly shot the victim, Melvin McCoy, who, after being transported to the hospital, was placed on life-support systems. See State v. Guess, supra, 244 Conn. at 764-66, 715 A.2d 643. A short time later, it was determined that McCoy could not sustain either circulatory or respiratory function on his own. Id., at 766, 715 A.2d 643. It also was determined that McCoy was "brain dead" because he exhibited no sign of any brain activity. Id. After McCoy's parents authorized the hospital to remove him from life support, he was pronounced dead. Id.

A jury found Guess guilty of McCoy's murder. Id., at 763, 715 A.2d 643. Following his conviction, Guess appealed to the Appellate Court, claiming that the evidence was insufficient to support a finding of probable cause that he had killed McCoy because, Guess maintained, the legal cause of McCoy's death was his removal from life-support systems rather than Guess' shooting of McCoy. See id. In particular, Guess contended that, "because the legislature had not adopted the Uniform Determination of Death Act,^[88] and *88 because the legislature did not define death in the Penal Code to include brain death, the court, in determining who or what caused [McCoy's] death, must use a common-law definition of death, which does not include brain death ... but rather depends solely [on] the cessation of circulatory and respiratory functions of the body." Id., at 766-67, 715 A.2d 643. The Appellate Court rejected Guess' claim, "concluding that the proximate cause of [McCoy's] death was the bullet wound he had sustained, and the act of disconnecting the life support systems after [McCoy] had been declared brain dead was a medically reasonable act that neither caused [McCoy's] death nor constituted a sufficient intervening cause so as to negate [Guess'] acts as the cause of death." Id., at 763-64, 715 A.2d 643, citing State v. Guess, 44 Conn.App. 790, 800, 692 A.2d 849 (1997).

Upon our granting of Guess' petition for certification to appeal, we concluded that, even if the legislature had not adopted the Uniform Determination of Death Act as the operative definition of death under the Penal Code, we could, "as a matter of common-law adjudication, define [the] term [death] in tandem with medical science and technology as they [had] evolved in recent years." State v. Guess, supra, 244 Conn. at 771, 715 A.2d 643. After noting the developments that had led to an expanded definition of death in the medical and legal fields; see id., at 772-78, 715 A.2d 643; we "construe[d] the meaning of `death' as that term is used in the Penal Code to include a brain-based definition of death"; id., at 780, 715 A.2d 643; thus placing the common-law definition of death in conformance with the definition of that term under the Uniform Determination of Death Act. See footnote 88 of this opinion. We therefore determined, for purposes of our common law, that an individual is deemed to be dead if that person has sustained either irreversible cessation of circulatory and respiratory functions or irreversible cessation of all functions of the entire brain, including the brain stem. See State v. Guess, supra, at 780, 715 A.2d 643.

In reaching our conclusion, we emphasized that "our recognition of brain-based criteria for determining death [was] not unfaithful to any prior judicial determinations. Death remains the single phenomenon identified at common law; the supplemental criteria are merely adapted to account for the changed conditions that a dead body may be attached to a machine so as to exhibit demonstrably false indicia of life. It reflects an improved understanding that in the complete and irreversible absence of a functioning brain, the traditional loci of lifeโ€”the heart and the lungsโ€”function only as a result of stimuli originating from outside of the body and will never again function as part of an integrated organism." (Internal quotation marks omitted.) Id., at 780-81, 715 A.2d 643.

In light of our determination in Guess concerning the applicability of the brain death standard, we concluded that the trial court in that case properly had found probable cause to charge Guess with the crime of murder. Id., at 781, 715 A.2d 643. Specifically, we stated: "Because the trial court at the hearing in probable cause reasonably found that [Guess'] act of shooting [McCoy] caused extensive brain damage, leaving [McCoy] with no evidence *89 of brain function, the court properly found that the state had established probable cause to charge [Guess] with the crime of murder." Id.

On appeal to this court, the defendant in the present case concedes that the brain death standard that we adopted in Guess was not intended to supplant the traditional common-law definition but, rather, merely to supplement it as an alternative basis for establishing when death has occurred. He contends, nevertheless, that, because the court in Guess recognized that a person who is being sustained on life support may have died, that is, the person may be brain dead, even though that person continues to exhibit traditional signs of life, namely, circulatory and respiratory functions, the state's burden of proving that Antonia was born alive required the state "to disprove any reasonable hypothesis arising from the evidence that [Antonia] actually died before she was extracted from the womb ... and placed on life support." (Emphasis added.) The defendant maintains, moreover, that the state's evidence failed to meet this standard because the testimony of Palmer, the emergency department physician who delivered Antonia, was based solely on the fact that Antonia had a heartbeat and was breathing after she had been placed on a ventilator. The defendant further claims that, in light of the testimony of Harold Wayne Carver II, the state's chief medical examiner, that Antonia's brain was "badly damaged" and "contained areas of atrophy or wasting away of the tissues" as a result of prenatal oxygen deprivation, there is a very real possibility, which the state was required to disprove, that Antonia was brain dead at the time of her birth and, therefore, was not a "person" within the meaning of the state's murder statute.

In response, the state contends that evidence of brain function never has been required to prove a live birth. The state therefore asserts that the defendant's reliance on Guess is misplaced and that Guess merely stands for the proposition that removing a person from life support does not bar a defendant's conviction for murder when the evidence establishes that the defendant's actions caused an irreversible cessation of that person's brain function before the removal of life support. In the state's view, Guess neither directly addressed nor implicitly resolved the issue raised by the present case, that is, whether an infant who, following her delivery, is placed on life support and sustained for forty-two days before being removed from life support, qualifies as a "person" within the meaning of our murder statute.^[89]

Before turning to the merits of the defendant's contention, we note that, at trial, the defendant never raised the evidentiary insufficiency claim that he now raises on appeal. Although defense counsel moved for a judgment of acquittal at the close of the state's case-in-chief on the ground of insufficiency of the evidence, his claim was based primarily on the contention that the state had failed to prove that *90 the defendant had the intent necessary to support his conviction for the murder of Antonia because she was a fetus when he engaged in the conduct that caused her death. Thus, the claim of evidentiary insufficiency that defense counsel raised at trial differs markedly from the claim the defendant raises on appeal. Furthermore, the defendant, like the state, does not contend that the panel actually applied a brain function standard in determining that Antonia was born alive.

We agree with the state that Guess does not directly address the issue of what type of proof or evidence is required to establish that an infant who is delivered by cesarean section after suffering prolonged oxygen deprivation in utero and is immediately placed on life support is a "person" within the meaning of our murder statute. Indeed, Guess did not present a factual scenario that required us to consider that question. More importantly, it is clear that the panel in the present case did not apply Guess or otherwise consider what relevance, if any, that case might have with respect to the issue of Antonia's status at the time of her birth. It is apparent, rather, that the panel, in determining her status, applied the traditional common-law test pursuant to which an infant is born alive if she has circulatory and respiratory functions that are independent of her mother. Indeed, our review of the record indicates that Guess was mentioned only once in the entire course of the trial. That occurred when defense counsel, at the close of the state's case-in-chief, moved for a judgment of acquittal on the ground of evidentiary insufficiency. At that time, defense counsel primarily argued that the state had failed to prove that the defendant possessed the requisite intent to murder Antonia because she was still a fetus, and not a person, when the defendant inflicted the injuries on Rodgers that ultimately caused Antonia's death; defense counsel also asserted, however, that the state had failed to prove that the defendant's conduct, and not the actions of medical personnel in removing Antonia from life support, was the proximate cause of Antonia's death. In support of this latter contention, defense counsel relied on Guess, explaining that, in contrast to the proof that had been adduced by the state in Guess, there was no evidence tending to establish that Antonia was brain dead when she was removed from life support.^[90] Thus, at trial, defense counsel contended that the evidence established that Antonia could have been alive when life support was removed, and that removing her from life supportโ€”not the defendant's conductโ€”had caused her death. In light of the foregoing argument, it is apparent that the defendant, like the state, viewed Guess merely as a causation case.^[91]

At no time, moreover, did the defendant seek to establish, through Palmer or any other witness, that Antonia was brain dead at the time of her birth. To the contrary, consistent with the aforementioned theory of defense, defense counsel apparently elicited testimony from Palmer *91 that Antonia was alive when she was born and up until six weeks after being delivered, at which time she was removed from life support. The state, moreover, presented no evidence, through Palmer or otherwise, as to whether Antonia had demonstrated brain function at the time of her birth or thereafter. The state's failure to adduce any evidence of brain function as part of its case and its argument on appeal that Guess is inapplicable to the issue of whether Antonia was born alive compel the conclusion that the state did not believe that it was required to establish brain function and therefore never sought to demonstrate any such function with respect to the born alive issue. In light of defense counsel's contention at trial concerning the import of Guess, it is equally evident that the defense also did not believe that the state had any obligation to satisfy a brain function standard. Finally, and significantly, there is nothing in the record to suggest that either the court, Damiani, J., or the panel applied the standard set forth in Guess in determining whether Antonia had been born alive.

Thus, although the claim of evidentiary insufficiency that the defendant raises in this court is predicated on the application of a test for determining whether a person is alive that requires due consideration of the principles articulated in Guess, it is apparent that, in the trial court, neither the parties nor the court had any such test in mind. For the reasons set forth in part V B of this opinion, we conclude that the panel improperly failed to apply the Guess standard for purposes of determining whether Antonia was born alive. More specifically, we conclude that, in light of the fact that, as in Guess, a person whose circulatory and respiratory functions are sustained by life support nevertheless may have suffered brain death, it necessarily follows that, to prove beyond a reasonable doubt that Antonia was alive at birth, the state must disprove that she was brain dead at birth. The proper remedy for the panel's use of the wrong legal standard is a new trial, however, not a judgment of acquittal.^[92] Cf. State v. DeJesus, supra, 288 Conn. at 434, 953 A.2d 45 ("[i]t is well established that instructional impropriety constitutes `trial error' for which the appropriate remedy is a new trial, rather than a judgment of acquittal").

A

Standard Utilized by the Trial Court and the Sufficiency of the Evidence Under That Standard

Before addressing the defendant's claim under Guess, we first address his claim that the evidence was insufficient *92 to prove beyond a reasonable doubt that Antonia was born alive under the standard that the panel applied. Although this claim, like the defendant's claim under Guess, was not preserved at trial, we nevertheless review it "because any defendant found guilty on the basis of insufficient evidence has been deprived of a constitutional right ... and would therefore necessarily meet the four prongs of [State v.] Golding [213 Conn. 233, 239-40, 567 A.2d 823 (1989)]."^[93] (Internal quotation marks omitted.) State v. King, 289 Conn. 496, 519, 958 A.2d 731(2008). We conclude that the evidence adduced at trial was sufficient to satisfy the born alive standard that the panel had applied.

The following additional facts and procedural history are relevant to our analysis of this issue. In finding that Antonia was born alive, the panel made no specific factual findings of its own. Rather, the panel relied on the law of the case and, in particular, on the pretrial ruling of the court, Damiani, J., on the motion to dismiss that the defendant filed immediately prior to the probable cause hearing. The only witness to testify at the probable cause hearing regarding Antonia's condition at birth was Palmer, the emergency department physician who delivered her. According to Palmer, after it was determined that Rodgers could not be resuscitated, he delivered Antonia by emergency cesarean section. After cutting and clamping the umbilical cord, he immediately handed Antonia to a physician's assistant, who was a member of the pediatric staff standing by to take Antonia to the pediatric intensive *93 care unit for resuscitation. Because Palmer transferred Antonia to the physician's assistant so quickly, his observations of her were extremely limited. He did observe, however, that she was not breathing or making sounds. Approximately thirty minutes after the delivery, Palmer went to the pediatric intensive care unit to treat a laceration that Antonia had suffered during the cesarean section. At that time, her vital signs were stable and she was breathing with the assistance of a ventilator. Palmer thereafter completed the appropriate paperwork for the issuance of Antonia's birth certificate, signifying that she had been born alive. Over the next several weeks, Palmer often checked on Antonia, who continued to exhibit stable vital signs with the assistance of the ventilator until she died six weeks after being delivered. On the basis of these facts, Palmer concluded that Antonia "was born, she was alive, and she died...." The state adduced no other testimony to establish that Antonia was born alive.

On cross-examination, defense counsel asked Palmer how much time had elapsed between Rodgers' arrival at the hospital and Antonia's birth. When the state's attorney objected to the question on relevancy grounds, defense counsel explained that he was "trying to determine whether the child was born alive or dead. And the time between when the mother came into the hospital and when the baby was delivered is very significant. The time clearly was of the essence because [Palmer] has already testified to the fact that [medical personnel] didn't do any monitoring of the fetus in utero because of the situation." The court then asked defense counsel why the question was relevant in view of the fact that Palmer already had testified "that the baby was born alive." Defense counsel responded: "He testified to that, but whether he had the basic facts to give that opinion, we don't know. I'm just testing whether he has the evidence to support [it]." The state's attorney interjected that "you don't ... have to be a doctor to know whether a baby is born alive or dead.... The baby lived for [six] weeks." The court overruled the state's attorney's objection but observed that Palmer had delivered Antonia and testified that she "was born alive. [Palmer is] a human being. He has an infant or a baby in his hands or arms that he passes off, and he can tell if the baby is born alive or not." The court further observed that, in light of Palmer's testimony, it did not view the amount of time that had elapsed between Rodgers' arrival at the hospital and Antonia's birth as "relevant, but ... we'll see where you are going."

Thereafter, defense counsel showed Palmer a copy of Antonia's birth certificate, which indicated that she had been born at 12:16 a.m., shortly after Rodgers had been brought to the emergency department. He then asked Palmer whether he was "aware of what constitutes a fetal death in the state of Connecticut...." The state's attorney objected, and the court inquired of defense counsel as to the relevancy of the question. Defense counsel responded: "Again, the issue is whether the child was born alive or not. I understand what the doctor's opinion was, but I think this is relevant to his knowledge of Connecticut law, which is what we are dealing with here." The state's attorney responded: "[T]he doctor has said that the baby was born alive. I know doctors are great, but I don't think when somebody is born dead, they can bring them back to life for [six] weeks.... This is ridiculous. It's ludicrous, these questions." The court overruled the state's attorney's objection, and Palmer then stated the he did not know "[t]he specifics of Connecticut law...." Defense counsel asked Palmer whether, when he delivered Antonia, he *94 had examined her to determine whether she had a heartbeat and was breathing. Palmer responded that he had done nothing except cut and clamp the umbilical cord, and hand Antonia over to the physician's assistant who was waiting to take her to the pediatric intensive care unit. Specifically, Palmer stated that he personally had observed "[n]o sounds," "[n]o crying," and "no breathing."

After defense counsel had finished questioning Palmer, the court indicated that it had a few questions. The court then asked Palmer what, in his medical opinion, constitutes a "fetal death...." Palmer responded, "[t]hat's when the heart stops and the baby's no longer viable." The trial court also asked Palmer whether Antonia was breathing and had a heartbeat when he visited her thirty minutes after her birth. Palmer responded that, at that time, Antonia's heart was beating and she "was breathing on a ventilator."

In its decision finding that the state had established probable cause to conclude that Antonia was born alive and, therefore, that she was a person for purposes of our Penal Code, the court stated in relevant part: "[The] court finds that the definition of a `person' in Connecticut criminal law includes those who are born and are alive. This definition does not exclude Antonia.... Palmer ... testified at the probable cause hearing that Antonia was born and remained alive for forty-two days before she succumbed to her injuries.

"This interpretation of the statute's applicability to the facts of the present case finds support in the [common-law] `born alive' rule." State v. Courchesne, supra, 46 Conn.Supp. at 67-68, 757 A.2d 699. The only other portion of the decision that is relevant to the court's finding that Antonia was born alive is the following explanation by the court as to why the doctrine of transferred intent applied in the born alive context: "Obviously, there are many instances [in which] an adult victim has died some considerable time after the infliction of the fatal blow or wound. If the victim recovers and survives, whether by reason of medical or surgical treatment, or otherwise, there is no homicide; yet, if the victim dies from such wounds, it is murder. While such medical or surgical treatment may be a so-called intervening factor between the point of infliction of injury and [the] resultant survival or death, nevertheless, the issue of homicide is resolved by the initial circumstances that caused the death.

"There is no logical reason why any different rule should apply to an unborn fetus who is successfully delivered alive and lives independent[ly] of his mother for a reasonable time; at least for [a] sufficient time so as not to be `stillborn,' as that term is accepted by the medical profession and our society."^[94] Id., at 75, 757 A.2d 699. A stillborn baby is a baby that is dead at birth or that has died before birth. See Stedman's Medical Dictionary (28th Ed. 2006), p. 1838 (defining "stillborn" as "[b]orn dead; denoting an infant dead at birth," and defining "stillbirth" as "[t]he birth of an infant who has died before delivery").

On the basis of the foregoing, it is evident that the court determined that Antonia had been "born and remained alive for forty-two days"; State v. Courchesne, supra, 46 Conn.Supp. at 67, 757 A.2d 699; merely because she had demonstrated vital signs while being sustained on life support for that extended period of time. This is so because the state presented no other evidence at the probable cause hearing *95 with respect to the born alive issue. That the court relied solely on the fact that Antonia had been sustained on a ventilator for forty-two days in concluding that she had been born alive also is evidenced by virtue of his questioning of Palmer regarding the meaning of "fetal death...." Palmer responded that fetal death occurs "when the heart stops and the baby's no longer viable." The court then asked Palmer whether Antonia's heart was beating and whether she was breathing when he examined her approximately thirty minutes after birth. Palmer responded in the affirmative but noted that she was breathing with the assistance of a ventilator. Thus, under the test that the court applied, an infant is born alive, even if she is not breathing at birth, as long as her circulatory and respiratory functions are maintained by life-support systems for a period of time.

Following the trial court's finding of probable cause, the guilt phase of the trial ensued before the panel. During the guilt phase, the state's attorney presented essentially the same evidence that he had adduced at the probable cause hearing. In addition, the state adduced testimony from Carver, the state's chief medical examiner, who had performed an autopsy on Antonia. Carver classified Antonia's death as a homicide and described Antonia as a "normal appearing infant" who weighed approximately ten pounds at the time of death, that is, several hours after ventilation support had been withdrawn. According to Carver, Antonia's size and development were consistent with that of a six week old baby.^[95]

The panel thereafter found the defendant guilty as charged. In doing so, the panel adopted the born alive test that the court, Damiani, J., had applied. Specifically, in its memorandum of decision on the defendant's motion for articulation, the panel stated in relevant part: "Judge Damiani issued a ... comprehensive opinion resolving the issue of the `born alive' rule as it applies to murder and capital felony in the state of Connecticut.... [The panel] has adopted that ruling and utilized Judge Damiani's analysis in concluding as it did that the defendant is guilty of murder and capital felony as charged...."^[96] (Citation omitted.)

In light of the nature of the test that the panel applied, it is apparent that the evidence adduced by the state at trial was sufficient to meet that test. As we previously explained, the traditional common-law definition of death was satisfied by evidence establishing the irreversible cessation of circulatory and respiratory functions. Conversely, proof of "life" merely required evidence of circulatory and respiratory functions. See, e.g., People v. Selwa, 214 Mich.App. 451, 463-64, 543 N.W.2d 321 (1995) ("the definition of `life' logically flow[s] from the ... definition of `death,'" and, "[a]ccordingly, a child is `born alive' and thus a `person' ... if, following expulsion or extraction from the mother, there is lacking an irreversible cessation of respiratory and circulatory *96 functions"), appeal denied, 453 Mich. 937, 557 N.W.2d 307 (1996); see also State v. Cornelius, supra, 152 Wis.2d at 277, 448 N.W.2d 434 ("[w]e accept as axiomatic the legal, if not medical, proposition that if one is not dead, he is indeed alive").

In the present case, the uncontroverted evidence established that Antonia was delivered in the emergency department at the hospital and subsequently placed on a ventilator that maintained her lung function, which, in turn, assisted her heart function. While on life support, Antonia grew at about the same rate as any other infant would have in the course of six weeks. Antonia remained on life support for forty-two days until it was withdrawn, after which she died. Because Antonia's bodily functions, including her circulatory and respiratory functions, continued, independently of her mother, for six weeks following her delivery, the state's evidence was sufficient to satisfy the standard that the panel applied during the guilt phase of the defendant's trial.

In connection with his claim that he is entitled to a judgment of acquittal on the ground of evidentiary insufficiency, the defendant appears to presume that the panel applied a test pursuant to which the state was required to prove that Antonia lived or was able to live independently of her mother and independently of life support. This presumption is manifested by the defendant's reliance on several cases that, he asserts, stand for that general proposition.^[97] It is true that a few courts, in refining the traditional common-law test for purposes of applying that test when an infant has been placed on life support immediately after delivery, have held that the infant will be deemed to have been born alive only if the evidence establishes that he or she had an existence independent of artificial support. See, e.g., State v. Lamy, supra, 158 N.H. at 517-18, 969 A.2d 451; State v. Dellatore, 761 A.2d 226, 230-31 (R.I.2000). The law in this area, however, is neither uniform nor well developed, and some courts have failed to articulate any such additional requirement. *97 See Regina v. Iby, supra, 63 N.S.W.L.R. at 285-87 (surveying case law of Australia, United States, England and Ireland and concluding that there is "[no] support [for] the ... contention that unassisted breathing must exist before a baby can be said to have been born alive").

For purposes of our analysis, however, the decisive consideration is the fact that the defendant never claimed that such a test applied, that neither the court, Damiani, J., nor the panel ever mentioned or otherwise adverted to a standard requiring evidence that Antonia was capable of living independently of life support, and that no evidence relative to any such standard was adduced by either party. It therefore is clear that both the court, Damiani, J., and the panel used a test pursuant to which Antonia was deemed to have been born alive merely because, as the court stated, she was "successfully delivered... and live[d] independent[ly] of [her] mother for a reasonable time; at least for [a] sufficient time so as not to be `stillborn,' as that term is accepted by the medical profession and our society." State v. Courchesne, supra, 46 Conn.Supp. at 75, 757 A.2d 699. Thus, to the extent that some courts have adopted a born alive standard that requires proof that the baby lived independently of life support, that was not the standard that the court, Damiani, J., or the panel applied. For the reasons set forth hereinafter, we conclude that the proper test requires proof that the baby was not brain dead at the time of birth, and, therefore, the defendant is entitled to a new trial at which the state will be required to meet that standard.

B

The Applicable Standard Under Guess

We turn, therefore, to the defendant's claim that the state was required but failed to prove that Antonia was not brain dead for purposes of establishing that she was born alive. We begin our analysis by noting our disagreement with the state's contention that the issue that we decided in Guess, namely, when life ends for purposes of proving causation in a homicide case, has no bearing on the question of when life begins for purposes of determining whether an infant has been born alive under the born alive rule. Although its relevance may not be readily apparent, our determination in Guess that a person may be dead even though he or she exhibits traditional indicia of life, that is, a heartbeat and respiration, is highly relevant to the issue of whether Antonia was alive at birth. We incorporated brain death into our common-law definition of death in Guess precisely because a person in extremis can be kept alive with the aid of life support even though that person already may have suffered an irreversible cessation of brain function. See State v. Guess, supra, 244 Conn. at 780, 715 A.2d 643. We explained in Guess that, under the common law, a person was not considered dead unless he or she had suffered an irreversible cessation of the circulatory and respiratory systems; id., at 772, 715 A.2d 643; and that would seem to hold true even if those systems were functioning only with the aid of life support. See People v. Mitchell, 132 Cal.App.3d 389, 396, 183 Cal.Rptr. 166 (1982) ("In many cases ... life support equipment can maintain an expired person's circulation and respiration artificially. A respirator can maintain physical breathing, as well as balance oxygen and carbon dioxide levels. However, if the victim has been without respiration long enough to have caused permanent and irreversible brain damage, the victim will forever remain in a vegetative state, a mere repository for organs capable of surviving if transplanted elsewhere, but incapable of regenerating the *98 brain of the corpse in which they are contained. Under the common law definition of death, the patient is alive."); see also Law v. Camp, 116 F.Supp.2d 295, 304 (D.Conn.2000) ("[b]ecause advances in medical technology [have] made it possible for ... bodily functions to continue in the absence of any brain function, a person on a mechanical ventilator would not be legally dead under the common law definition of death"), aff'd, 15 Fed.Appx. 24 (2d Cir. 2001), cert. denied, 534 U.S. 1162, 122 S.Ct. 1172, 152 L.Ed.2d 116 (2002); cf. Strachan v. John F. Kennedy Memorial Hospital, 109 N.J. 523, 532, 538 A.2d 346 (1988) ("For organs to be preserved for transplant, the donor's cardiopulmonary system must continue functioning until the organs can be removed. Under the traditional definition of death, [however] such a donor would be considered as still alive because the heart continues to beat and the lungs continue to perform the respiratory function."). In view of the fact that such a person is not truly alive in the way that we have come to understand or appreciate what it means to be alive, we deemed it appropriate to expand the common-law definition of death to include brain death. See State v. Guess, supra, at 780-81, 715 A.2d 643. As we stated in Guess, "it has become clear in medical practice that the traditional vital signsโ€”breathing and heartbeatโ€”are not independent indicia of life... but are, instead, part of an integration of functions in which the brain is dominant.... [Therefore] our focus must shift from those traditional vital signs to recognize cessation of brain functions as [a criterion] for death following this medical trend." (Citation omitted; internal quotation marks omitted.) Id., at 776, 715 A.2d 643. In Guess, however, we had no reason to address the question of how the brain function standard would operate, if at all, in the context of a case that, like the present one, implicates the born alive rule.

It is apparent, however, that application of the traditional common-law test to determine whether Antonia was born alive, as the court, Damiani, J., and the panel did in this case, does not account for the possibility that Antonia could have been brain dead at birth even though her respiratory and circulatory functions were sustained for forty-two days with the assistance of life support.^[98] If, in fact, that was the case, the defendant could not be held criminally responsible for her death under our murder statute because, in such circumstances, she would have died in utero, and, consequently, she would not be a "person" within the meaning of our murder statute.

In Guess, this court expanded the definition of death for purposes of the Penal Code to include brain death as well as the traditional test that requires proof of the irreversible cessation of circulatory and respiratory functions. See id., at 780, 715 A.2d 643. We did so both because the medical and scientific communities have long accepted the brain based standard for defining death; id., at 777, 715 A.2d 643; and in recognition of the fact that "medical science and technology [have] evolved to the point where a person's heartbeat and respiration may be sustained mechanically even in the face of an irreversible loss of all brain functions, and where machines that artificially maintain cardio[pulmonary] [function] have come into widespread use." Id., at 772, 715 A.2d 643; see also State v. *99 Lamy, supra, 158 N.H. at 518, 969 A.2d 451 ("As medical technology has advanced... so too has the born alive rule. Through the efforts of doctors and technology, a fetus can now be delivered with no heartbeat, no breathing, and no brain function, yet have [certain of] those functions artificially resuscitated and maintained some time later. Because of these advances, states employing the born alive doctrine have required that the child show some spontaneous sign of life, as well as the ability to exist independent[ly] of artificial support at some point in the future."), citing Alaska Stat. ง 11.41.140 (2008) (providing that "[a] person is `alive' if there is spontaneous respiratory or cardiac function or, when respiratory and cardiac functions are maintained by artificial means, there is spontaneous brain function"). In such circumstances, when an individual is maintained on life support despite the complete absence of brain function, death has occurred under the brain death standard that we adopted in Guess even though, due to mechanical intervention, there has been no irreversible cessation of circulatory and respiratory functions. In that case, therefore, the fact that there has been no irreversible cessation of circulation and respiration functions does not signify life. Similarly, when, as in the present case, an infant's circulatory and respiratory functions have been maintained artificially since immediately after her birth, the state must establish that she was not brain dead at the time of birth in order to satisfy the requirement that she had been born alive.^[99]

The state contends that this evidentiary standard is unworkable in light of the medical exigencies that frequently exist at the time of birth. According to the state, requiring proof of brain function to establish that a baby had been born alive "would make it far more difficult to establish homicide and, consequently, far more likely that the person who injured the baby could not be held accountable for causing her death." Although we acknowledge that, depending on the circumstances, satisfying a brain death standard may require greater proof than would be necessary under the traditional born alive rule, that fact alone does not dictate the test to be adopted because "brain death became the medically accepted standard for determining death some time ago." State v. Guess, supra, 244 Conn. at 777, 715 A.2d 643. Moreover, in the present case, if Antonia was, in fact, born alive, there is every likelihood that the state will be able to prove it. Indeed, the hospital may have performed one or more tests over the forty-two days when Antonia was on life support that would establish the existence of brain function. Alternatively, there may be evidence indicating that, at some point prior to the time that Antonia was pronounced dead following her removal from life support, she reacted to certain stimuli or otherwise engaged in activity or spontaneous movements that are incompatible with brain death. Cf. id., at 773, 715 A.2d 643 ("[t]he criteria by which the medical community determines brain death ... include: [1] a total lack of responsivity to externally applied stimuli; [2] no spontaneous muscular movements or respiration; and [3] no reflexes, as measured by fixed, dilated pupils and lack of ocular, pharyngeal and muscle-tendon reflexes"). In such circumstances, the state presumably *100 could establish that Antonia was not brain dead at birth by showing, for example, that she breathed on her own or that she coughed or cried or otherwise exhibited some spontaneous sign of life after birth.^[100]

We recognize that other courts have declined to adopt a brain death standard for purposes of the born alive rule. See People v. Bolar, supra, 109 Ill.App.3d at 391, 64 Ill.Dec. 919, 440 N.E.2d 639 ("[The] contention that brain activity [is] required for a finding of live birth is a luxury that is impossible to afford. Testimony at trial indicated that this could only be conclusively established through use of an electroencephalogram. [Although] no testimony was adduced we believe that constraints of time, availability of equipment, and incompatibility with life-saving measures [render] this requirement totally impractical."); see also Regina v. Iby, supra, 63 N.S.W.L.R. at 289-90 (rejecting claim that common law should be adapted so that definition of life coincides with statutory definition of death, which includes brain death); cf. People v. Hall, supra, 158 App. Div.2d at 74, 557 N.Y.S.2d 879 (looking at respiratory and circulatory functions, as well as voluntary movement of muscles, as signs that infant has been born alive). We are not persuaded, however, by the analysis and conclusion of those cases, which, in our view, give insufficient consideration to the fact that a baby can be maintained by artificial means even though she has no brain function. Indeed, the holdings of those cases are inconsistent with our holding in Guess, which we expressly reaffirm. We therefore conclude that, on retrial, the state will be required to establish that Antonia was not brain dead at the time of her birth.^[101]

PENALTY PHASE CLAIMS

The defendant also challenges the sufficiency of the evidence presented by the *101 state at the penalty phase hearing. Specifically, the defendant first contends that the evidence was insufficient to prove beyond a reasonable doubt that the defendant had committed the capital felony "in an especially heinous, cruel or depraved manner" as ง 53a-46a(i)(4) requires. Second, the defendant contends that the state failed to prove that he had intended to murder Rodgers in such a manner. Third, the defendant contends that the jury reasonably could not have found that the aggravating factor outweighed any mitigating factor or factors in accordance with ง 53a-46a(f). We reject the defendant's claims.^[102]

"[W]e have interpreted the aggravating factor set forth in ง 53a-46a(i)(4) to require proof that the defendant engaged in intentional conduct that inflicted extreme physical or psychological pain [suffering] or torture on the victim above and beyond that necessarily accompanying the underlying killing, and that the defendant specifically intended to inflict such extreme pain [suffering or] torture ... or ... the defendant was callous or indifferent to the extreme physical or psychological pain, suffering or torture that his intentional conduct in fact inflicted on the victim....

"In reviewing a claim that the evidence fail[ed] to support the finding of an aggravating factor specified in [ง 53a-46a(i)]... we subject that finding to the same independent and scrupulous examination of the entire record that we employ in our review of constitutional fact-finding, such as the voluntariness of a confession... or the seizure of a defendant.... In such circumstances, we are required to determine whether the factual findings are supported by substantial evidence....

"Even with the heightened appellate scrutiny appropriate for a death penalty case, the defendant's challenge to the sufficiency of the evidence of aggravating circumstances must be reviewed, in the final analysis, [first] by considering the evidence presented at the defendant's penalty [phase] hearing in the light most favorable to sustaining the facts impliedly found by the jury.... Second, we determine whether upon the facts so construed and the inferences reasonably drawn therefrom the [finder of fact] reasonably could have concluded that the cumulative force of the evidence established [the existence of the aggravating factor] beyond a reasonable doubt.... This court cannot substitute its own judgment for that of the jury if there is sufficient evidence to support the jury's verdict....

"Furthermore, [i]n viewing evidence [that] could yield contrary inferences, the jury is not barred from drawing those inferences consistent with [the existence of the aggravating factor] and is not required to draw only those inferences consistent with [its nonexistence]. The rule is that the jury's function is to draw whatever inferences from the evidence or facts established by the evidence it deems to be reasonable and logical....

"[Finally], [i]n [our] process of review, it does not diminish the probative force of the evidence that it consists, in whole or in part, of evidence that is circumstantial rather than direct.... It is not one fact, but the cumulative impact of a multitude of facts [that] establishes [the *102 existence of an aggravating factor] in a case involving substantial circumstantial evidence.... Indeed, direct evidence of the defendant's state of mind is rarely available.... Therefore, intent is often inferred from conduct ... and from the cumulative effect of the circumstantial evidence and the rational inferences drawn therefrom." (Citations omitted; internal quotation marks omitted.) State v. Colon, supra, 272 Conn. at 335-37, 864 A.2d 666.

The evidence that the state presented at the penalty phase hearing established that the defendant had caused the death of Rodgers, who was eight and one-half months pregnant, by stabbing her multiple times with a kitchen knife while the two were seated in the defendant's car. The defendant's statement to the police indicates that, on the night of the murder, he spoke with Rodgers on the telephone and told her that he had the $365 that he owed her boyfriend for drugs. The defendant told Rodgers that he would pick her up and take her to an automated bank teller machine at his bank, where he would withdraw the money. In his statement, the defendant explained that he "really had no intention of paying [Rodgers] because [he] did not have any money, [and he] was trying to fool her."

When they arrived at the bank, the defendant told Rodgers that he had forgotten his bank card. Rodgers became upset with the defendant, and, at that point, the defendant "just lost it ... grabbed a kitchen knife [that he kept] in the driver's door compartment and ... started to stab [Rodgers] with [it]." Although she tried to get away, he "just kept stabbing her." At some point, Rodgers escaped from the car and ran a short distance before she collapsed. The defendant then exited the car, intending "to chase her down." When he saw that there were several other cars in the vicinity, however, he became scared, got back into his car and drove away. As he was fleeing, he thought it was possible that he had run Rodgers over with his car. All he could think about at the time, however, was not getting caught.

The state also presented expert testimony regarding the nature of the wounds that the defendant inflicted on Rodgers. One of the state's associate medical examiners, Malka Shah, testified that Rodgers had sustained several injuries in a number of different places on her body, including a stab wound to her chest and seven stab wounds to her back. The chest wound measured five and one-half inches deep, and penetrated the right border of Rodgers' sternum and her heart. The most serious stab wound to Rodgers' back measured five inches deep and penetrated the abdominal cavity. According to Shah, the stab wounds to Rodgers' chest and abdomen had caused her death. In addition to these wounds, Rodgers also sustained a three inch wound to her face and another wound to her chin, both of which were caused by a sharp object. Rodgers also had cuts and bruising around her mouth, which were caused by premortem, blunt force trauma that was unlikely to have been caused by a fall. The evidence further established that Rodgers remained conscious for up to seven minutes after suffering the fatal chest wound and that she lived for up to fifteen minutes before finally succumbing to her injuries.

Having carefully considered the evidence adduced by the state, we conclude that it supported the jury's finding that the defendant killed Rodgers in an especially heinous, cruel or depraved manner. The jury reasonably could have found that the eight stab wounds, as well as the multiple wounds and blunt force trauma to Rodgers' face, caused her to experience extreme physical and psychological pain and suffering above and beyond that which *103 was necessary to accomplish the killing, and that she experienced such suffering for up to seven minutes. The jury also reasonably could have found that Rodgers' psychological pain and suffering were compounded by the terror of being subjected to such a vicious, spontaneous attack while pregnant, and that her pregnancy caused her to suffer additional psychological pain out of extreme concern for her nearly full-term child. See State v. Medrano, 173 Ariz. 393, 397, 844 P.2d 560 (1992) (victim's knowledge of her pregnancy "would likely have contributed significantly to her mental suffering").

We also conclude that the evidence supports the jury's finding that the defendant possessed the requisite intent to satisfy the aggravating factor. "It is axiomatic that the fact finder may infer intent from the natural consequences of one's voluntary conduct." (Internal quotation marks omitted.) State v. Colon, supra, 272 Conn. at 338, 864 A.2d 666. In light of the nature and number of wounds that the defendant inflicted on Rodgers with the knowledge that she was pregnant, the jury reasonably could have found that the defendant intended to inflict extreme physical and psychological pain and suffering on her. The jury also could have found that the defendant exhibited extreme indifference to the mental suffering that Rodgers no doubt experienced from being repeatedly stabbed in the abdomen while eight and one-half months pregnant. The jury also could have inferred extreme indifference toward Rodgers' suffering predicated on the defendant's statement to police that, when fleeing the scene, he did not "even know if [he] ran her over. [He] just didn't want to get caught." Accordingly, we conclude that there was sufficient evidence to support the jury's finding that the defendant murdered Rodgers with the intent to inflict extreme physical or psychological pain, suffering or torture on her above and beyond that necessary to accomplish the killing or that he was indifferent to the extreme pain, suffering or torture that he intentionally inflicted on her.

The defendant finally claims that, even if the evidence supports the finding of the jury that he murdered Rodgers in an especially heinous, cruel or depraved manner, the jury reasonably could not have found that that aggravating factor outweighed one or more mitigating factors. The state contends that, under our case law, the jury's determination as to the weight to be accorded the mitigating and aggravating factors is not reviewable on appeal. The state further maintains that, to the extent that such a determination is reviewable, the evidence presented at the penalty phase hearing permitted the jury rationally to conclude that the aggravating factor outweighed any asserted mitigating factors. Assuming without deciding that the defendant's claim is reviewable, we agree with the state that the evidence is sufficient to support the jury's determination that the aggravating factor outweighed any mitigating factor or factors.

The following additional facts and procedural history are relevant to our resolution of this claim. The defendant raised eighteen claims of mitigation, including two statutory mitigating factors under ง 53a-46a(h).^[103] The sixteen, nonstatutory mitigating *104 factors were: (1) "[The defendant] was found guilty of the murder of Antonia... under the doctrine of transferred intent"; (2) "[p]rior to his convictions for the murders in this case, [the defendant] had no record of criminal convictions"; (3) "[the defendant] developed a dependence on cocaine and crack cocaine that negatively affected him in his personal and work life"; (4) "[h]is cocaine and crack cocaine dependency led directly to his relationship with ... Rodgers"; (5) "[h]is thinking was impaired by the crack cocaine he ingested prior to stabbing ... Rodgers"; (6) "[h]e worked constantly and productively from the age of sixteen until ... he was arrested and incarcerated in September, 1998"; (7) "[h]e is a caring person who has been empathetic to other persons, particularly those with disabilities"; (8) "[h]e has been generous to others"; (9) "[h]e has and will continue to be a well behaved and productive prison inmate"; (10) "[h]e has volunteered his time, both when employed and while incarcerated, to work above and beyond what is required of him to the benefit of other persons and institutions"; (11) "[w]ith the exception of the murders that he has been convicted of, [the defendant] is a nonviolent person, and it is unlikely that he will behave violently in the future"; (12) "[h]e voluntarily gave written statements to Waterbury police"; (13) "[h]e is remorseful"; (14) "[d]eath is not the appropriate penalty for [the defendant]"; (15) "[a]ny other factor concerning [the defendant's] character, background and history, or the nature and circumstances of the crime, that has not been specifically suggested, which [a] juror or the jury may, in fairness and mercy, find is mitigating in nature and constitutes a basis for a sentence of life imprisonment without the possibility of release"; and (16) "[t]he cumulative or combined effect of all [of] the evidence concerning [the defendant's] character, background or history, or the nature or circumstances of the crime, which a juror or the jury may, in fairness and mercy, find mitigating in nature and constitutes a basis for a sentence of life imprisonment without the possibility of release." The jury concluded that the defendant had proved by a preponderance of the evidence one or more of the foregoing nonstatutory, mitigating factors, but it did not specify which factor or factors it found had been proven.

We begin our analysis with the standard of review. This court previously has indicated that appellate review of a jury's determination with respect to the weighing of aggravating and mitigating factors in a specific case could be impossible in the practical sense. In State v. Rizzo, 266 Conn. 171, 833 A.2d 363 (2003), we interpreted ง 53a-46a, our capital felony weighing statute, to require a jury to be convinced beyond a reasonable doubt that the aggravating factors outweigh the mitigating factors. Id., at 224-25, 833 A.2d 363. In so concluding, we recognized "that there is not a risk of error in such a decision in the usual sense of that term, namely, the risk of being wrong in determining the historical facts, such as who did what to whom." Id., at 237, 833 A.2d 363. We noted, however, that "there [can] be a risk of error in a more practical sense, namely, the risk that, in making the determination that the aggravating factors outweigh the mitigating factors and that the *105 defendant shall therefore die, the jury may weigh the factors improperly ... and may arrive at a decision of death that is simply wrong." Id. With that possibility in mind, we further observed that, "once the jury has arrived at such a decision pursuant to proper instructions, that decision would be, for all practical purposes, unreviewable on appeal save for evidentiary insufficiency of the aggravating factor"; id.; an observation that led us to impose on the state a heightened burden of persuasion under ง 53a-46a.

The state contends that, under Rizzo, the weighing process in which the jury engages is effectively unreviewable and that, consequently, we should decline to consider the defendant's challenge to that process in the present case. We need not address the state's threshold reviewability claim because we conclude that, in the present case, the jury reasonably could have found beyond a reasonable doubt that the aggravating factor that the state had proven outweighed the mitigating factors alleged by the defendant.^[104]

As we previously explained, the jury concluded that the defendant had proved by a preponderance of the evidence the existence of one or more mitigating factors, but it did not specify which factor or factors the defendant had proven. We conclude that, even if the jury had credited all of the mitigating factors advanced by the defendant, they were not so compelling that the jury was required to find that one or more of those mitigating factors outweighed the cruel, heinous or depraved manner in which the defendant had murdered Rodgers.

The evidence presented at the penalty phase hearing established that the defendant had induced Rodgers to get into his car under false pretenses and, thereafter, repeatedly had stabbed her in the chest and back as she fought for her life and the life of her unborn child. When Rodgers finally escaped from the car, the defendant got out of the car, knife in hand, intending to chase her down to make sure that she was dead. Only when he saw other cars in the vicinity and feared that he might be seen did he stop his vicious assault of Rodgers. In light of this undisputed evidence, in particular, the extensive nature of Rodgers' injuries, which, in addition to the numerous stab wounds, included blunt force trauma wounds to the face, we cannot say that the jury reasonably could not have found beyond a reasonable doubt that the aggravating factor outweighed the mitigating factors that the defendant had alleged.^[105]

*106 The judgment is reversed with respect to the defendant's conviction of both counts of capital felony and the count with respect to the murder of Antonia Rodgers and the case is remanded for a new trial on those counts; the judgment is affirmed with respect to the defendant's conviction of the murder of Demetris Rodgers.

In this opinion ROGERS, C.J., and KATZ and VERTEFEUILLE, Js., concurred.

KATZ, J., concurring.

Although many of the considerations and principles on which Justice Zarella relies in his concurring and dissenting opinion have strong appeal, both on their merits and because he reaches a result that would not expose the defendant to the death penalty, ultimately, I cannot overcome the anomalous result that his and Justice Schaller's concurring and dissenting opinions yieldโ€”a statutory scheme that makes an assault on a woman that results in the death of a fetus a class A felony under General Statutes ง 53a-59c, but imposes no enhanced penalty when the assault on the pregnant woman results in a live birth and the fetus subsequently dies as a result of the assault. Therefore, I join the majority opinion in its recognition of the born alive rule as a part of our common law.

Although I agree with the majority opinion insofar as the resolution of the issues it does decide, I disagree with its decision not to address additional claims related to the penalty phase of the proceedings that are likely to arise again at a subsequent penalty phase proceeding should the defendant, Robert Courchesne, be convicted of capital felony at the guilt phase because the majority's failure to consider those claims is contrary to the interests of every participant in the trial proceedings. Many of these claims pertain to matters on which the parties and the trial court undoubtedly will need guidance should a penalty phase proceeding transpire.^[1] Indeed, some of the claims would preclude the imposition of the death penalty.^[2] The parties and the trial court should not have to guess at how this court would decide these issues, risk making the same mistakes if indeed the defendant's claims have merit, and go through what could turn out to be a needless, costly and time-consuming exercise. We also may unnecessarily be exposing both the victim's family to the heartbreak of reliving their tragedy in another penalty *107 phase proceeding and the defendant to the anxiety of defending against another sentence of death. I acknowledge that the state may not convict the defendant of capital felony and caution that, by articulating the need to address these other issues, I do not mean to intimate that the defendant would be so convicted. In light of that caveat, I am less persuaded by a concern that we would be issuing an advisory opinion than I am compelled by the potential harm to the parties to the case, the victim's family and the interests of judicial economy that the majority risks by declining to address these claims.

Accordingly, I respectfully concur.

ZARELLA, J., with whom NORCOTT, J., joins, concurring in part and dissenting in part.

Today, the majority subjects the defendant to another trial for capital felony and murder by adopting, for the first time in the state of Connecticut, the born alive rule. In so doing, the majority, in an opinion of more than 160 pages, fails to demonstrate that the murder statute encompasses the acts alleged to have been committed, adds a substantive element of proof that does not appear in the statutes governing murder, thus making the killing of a fetus that dies after birth a new substantive offense not contained in our Penal Code, fails to establish that the born alive rule was ever adopted by the legislature, provides no convincing support for its view that the rule was a part of the common law of Connecticut and resorts to the legislative history of an act enhancing the penalty for an assault on a pregnant woman to conclude that the legislature has accepted the rule under our murder and capital felony statutes. In addition, the majority ignores the plain language of the murder statute, ignores or fails to address our precedent in the area of what constitutes the common law of Connecticut, disregards the due process rights of the defendant by relying on the legislature's purported acceptance of the rule more than four years after the crime was committed, fails to employ the rule of lenity to resolve the ambiguities in our murder and capital felony statutes as applied to the facts of this case,^[1] and, for the first time in any jurisdiction that I am aware of, establishes the proposition that the criminal act of murder does not require that the intent to murder be present either before or during the commission of the crime.

I cannot agree with this deeply flawed approach because, no matter how horrific or despicable the crime, it does not justify ignoring our precedent and the constitutional protections guaranteed to all defendants. Accordingly, I concur in part I of the majority opinion, in which the majority concludes that the trial court properly denied the defendant's motion to suppress his written confessions and other evidence tying him to the murder of Demetris Rodgers, but respectfully dissent with respect to parts II through V,^[2] in which the majority adopts the born alive rule, devises a legal standard for its implementation and remands the case for a new trial that will require the state to prove that the baby was alive at birth by disproving the irreversible cessation of all brain function. *108 I also generally agree with Justice Schaller's concurring and dissenting opinion because the majority's retroactive application of the born alive rule clearly deprives the defendant of his due process right to fair notice.

Justice Oliver Wendell Holmes once observed in a similar context: "It is revolting to have no better reason for a rule of law than that so it was laid down in the time of Henry IV. It is still more revolting if the grounds upon which it was laid down have vanished long since, and the rule simply persists from blind imitation of the past." O. Holmes, "The Path of the Law," Address at Boston University School of Law (January 8, 1897), in 10 Harv. L.Rev. 457, 469 (1897); cf. State v. Muolo, 118 Conn. 373, 378-79, 172 A. 875 (1934).^[3] Justice Holmes' observation is particularly apt in the present case because the dearth of medical knowledge that prompted articulation of the born alive rule in the early 1300s no longer exists, and, therefore, the grounds for its adoption have vanished.^[4]

It is well documented that the born alive rule evolved during a time of limited medical knowledge, when it was necessary to establish that a fetus was alive at the time of the criminal act. See, e.g., C. Forsythe, "Homicide of the Unborn Child: The Born Alive Rule and Other Legal Anachronisms," 21 Val. U.L.Rev. 563, 575 (1987) ("As a result of ... primitive knowledge of human life in utero, the health of the child in utero could not be established unless and until the child was observed outside the womb.... [L]ive birth was required to prove that the unborn child was alive and that the material acts were the proximate cause of death, because it could not otherwise be established if the child was alive in the womb at the time of the material acts."); see also Commonwealth v. Cass, 392 Mass. 799, 806, 467 N.E.2d 1324 (1984) (rationale offered for born alive rule since 1348, namely, that "it [was] difficult to know whether [the defendant] killed the child," no longer exists because "[m]edical science now may provide competent proof as to whether the fetus was alive at the *109 time of a defendant's conduct and whether his conduct was the cause of death" [internal quotation marks omitted]). The born alive rule thus was used as an evidentiary tool to confirm that the fetus had died due to the perpetrator's actions rather than to natural causes or other reasons that could not be identified by then existing diagnostic techniques. See State v. Lamy, 158 N.H. 511, 516, 969 A.2d 451 (2009) ("born alive rule emerged in fourteenth century England as an evidentiary standard requiring observation of the child to prove the corpus delecti^[5] in the killing of an infant"). As one nineteenth century expert on medical jurisprudence more fully explained: "It is well known that, in the course of nature, many children come into the world dead, and that others die from various causes soon after birth. In the latter, the signs of their having lived are frequently indistinct. Hence to provide against the danger of erroneous accusations, the law humanely presumes that every new-born child has been born dead, until the contrary appears from medical or other evidence. The onus of proof is thereby thrown on the prosecution; and no evidence imputing murder can be received, unless it be made certain, by medical or other facts, that the child survived its birth and was actually living when the violence was offered to it." (Emphasis added.) A. Taylor, Medical Jurisprudence (5th Am. Ed. 1861) p. 317; see also J. Reese, Text-book of Medical Jurisprudence and Toxicology (7th Ed. 1907) p. 216.^[6] Accordingly, prosecution for homicide under the born alive rule, as originally understood, did not depend on whether the fetus was born alive and thus became a "person" prior to its death but on whether the fetus was alive when the fatal injury was inflicted. See, e.g., C. Forsythe, supra, at 571 *110 ("[m]edical treatises and writings on medical jurisprudence during the [sixteenth] through [nineteenth] centuries testify to the primitive state of medical technology and the resulting evidentiary limitations which gave rise to ... the born alive rule"); see also Commonwealth v. Cass, supra, at 806, 467 N.E.2d 1324. In other words, if medical technology had been capable of assessing the health of the fetus in times past, there would have been no reason for creating the born alive rule. The perpetrator very likely would have been prosecuted for homicide regardless of whether the fetus had died before or after its birth. See C. Forsythe, supra, at 589 ("[i]n practice, the born alive rule was applied to proscribe as homicide the killing of a child even if the mortal injuries were inflicted while the child was still in utero").

Recognizing the evidentiary basis for the born alive rule and the advances in medical science that have made the rule obsolete,^[7] the overwhelming majority of our sister states have rejected it in favor of legislation defining homicide to include the death of an unborn child or fetus from injuries inflicted in utero. See Ala.Code ง 13A-6-1(a)(3) (Cum.Sup.2009) (defining "person," in referring to victim of homicide, as "a human being, including an unborn child in utero at any stage of development, regardless of viability"); Alaska Stat. งง 11.41.150, 11.41.160 and 11.41.170 (2008) (proscribing murder, manslaughter and criminally negligent homicide with respect to unborn child); Ariz.Rev.Stat.

The Supreme Judicial Court of Massachusetts also implicitly rejected the born alive rule when it determined that a defendant may be charged with homicide for causing the death of a viable fetus in utero. Commonwealth v. Cass, supra, 392 Mass. at 807, 467 N.E.2d 1324; see also id., at 799, 467 N.E.2d 1324 (ruling that viable fetus is within ambit of term "person" in vehicular homicide statute).^[8] The legislatures in Alabama, Arkansas, Idaho, Kansas, Mississippi, Oklahoma, South Dakota and Utah also have amended their penal codes to include an unborn child or fetus in the definition of a "person" or "human being," thus emphasizing that the *112 critical focus of the fetal homicide statutes is on life rather than birth. This is consistent with the rationale for creating the born alive rule in the first instance, because the rule always presumed that a viable fetus was a person. The requirement of a live birth was merely a mechanism to prove that the death of the fetus was caused by the defendant's act and not by some other cause.

The majority's adoption of the born alive rule has at least three deleterious consequences. First and foremost is that the court invades the legislative prerogative to define what is, and what is not, a crime, because the rule, as understood and applied by the majority, has the effect of amending the definition of a "person" under our murder statutes; see General Statutes ง 53a-3(1) (defining "person" as "a human being"); to include a fetus that is born alive but subsequently dies from injuries inflicted in utero, thus making the killing of such a fetus a new substantive offense. This court has acknowledged that, "in light of established doctrines implicit in the separation of powers, the primary responsibility for enacting the laws that define and classify crimes is vested in the legislature...." (Citations omitted.) State v. Joyner, 225 Conn. 450, 460, 625 A.2d 791 (1993); see also State v. Hanson, 210 Conn. 519, 529, 556 A.2d 1007 (1989) ("Where statutory language is clearly expressed... courts must apply the legislative enactment according to the plain terms and cannot read into the terms of a statute something which manifestly is not there in order to reach what the court thinks would be a just result.... It is axiomatic that the court itself cannot rewrite a statute to accomplish a particular result. That is the function of the legislature." [Citation omitted; internal quotation marks omitted.]); Commission to Revise the Criminal Statutes, Penal Code Comments, Conn. Gen.Stat. Ann. ง 53a-4 (West 2007), comment, p. 324 (court not "free to fashion additional substantive offenses" not included in Penal Code). Accordingly, in adopting the born alive rule and, in effect, amending the statutory definition of "person," the court exceeds its jurisdiction.

Second, the born alive rule, stripped of its relevance as an evidentiary tool, is logically incoherent and thus introduces a significant incongruity into our criminal law. As interpreted by the majority, the rule contains the inherent contradiction that a viable fetus that is fatally injured but subsequently born alive is considered a person under our murder and capital felony statutes but is not considered a person if it is not born alive. Thus, a viable fetus that is fatally injured in utero may or may not be a person for purposes of prosecuting an accused for murder or capital felony depending on the entirely random fact of its status at the time of its death, which may depend on such unforeseen factors as how soon the injured mother receives medical attention, how quickly the medical staff is able to perform the delivery, and the accuracy of the observations and tests administered by the delivery team to determine if the baby is born alive. This makes no sense whatsoever. Moreover, the majority's focus on the status of the fetus at the time of its death is completely at odds with the underlying rationale of the born alive rule, which considered whether the fetus was alive at birth only to establish its condition in utero at the time of the fatal injury. The majority thus severs the temporal connection between the criminal conduct and the status of the victim when the fatal injury was inflicted and allows pure happenstance to determine whether a perpetrator may be prosecuted for murder and subjected to the death penalty.

This, in turn, raises serious due process concerns regarding the right to fair notice *113 because whether criminal liability will attach for the death of a fetus in any particular case will not be evident to the perpetrator at the time the crime is committed. See State v. Aiwohi, 109 Hawai`i 115, 136, 123 P.3d 1210 (2005) (Acoba, J., concurring). The defendant in the present case also will have been denied his due process rights because the majority's retroactive application of its newly adopted construction of our murder statute will have deprived him of notice and fair warning regarding the consequences of his actions.

In summary, because the born alive rule developed as a rule of causation and is no longer necessary due to advances in medical science that now permit a determination to be made regarding the health of a fetus, there is no evidentiary justification for its perpetuation. Accordingly, adoption of the rule will have the effect of amending the definition of "person" under our Penal Code to include a fetus that is fatally injured but subsequently born alive. Amending our criminal statutes violates the separation of powers because it is well established that the legislature, not the court, has the undisputed authority to define crimes. In addition, the rule engenders confusion and threatens due process because it lacks logical consistency and deprives potential defendants of fair warning as to the consequences of their actions. The defendant in this particular case also will be deprived of fair notice because of the majority's decision to apply the rule retroactively. In my view, these reasons strongly militate against the rule's adoption.

II

The majority nonetheless embraces the born alive rule, concluding that, as long as the fetus that is fatally injured is subsequently born alive, the perpetrator can be charged with the murder of a person. Recognizing that this appears to be problematic, however, the majority states that Connecticut's murder statute does not require that the fetus be a person at the time of the criminal conduct but only that it become a person before it dies by being born alive. This interpretation of the murder statute is not only in direct conflict with the rule's original purpose of establishing that the fetus was alive when the fatal injury was inflicted, but requires a major rewriting of General Statutes ง 53a-54a.

The majority claims that there is nothing in our Penal Code or ง 53a-54a(a) suggesting that application of the born alive rule is barred by the requirement of a temporal nexus between the defendant's criminal conduct and the victim's status as a person, and that it is unaware of any other authority that requires one. I find this reasoning unpersuasive because an examination of the language of the murder statute, its relationship to other statutes, the authorities on which the majority relies and other authorities unequivocally demonstrate otherwise.^[9] See State v. Gibbs, 254 *114 Conn. 578, 601-606, 758 A.2d 327 (2000) (applying well settled principles of statutory interpretation to determine if temporal nexus between multiple murders is absolute prerequisite to proving that murders took place in course of single transaction for purposes of General Statutes [Rev. to 1991] ง 53a-54b[8]). In addition, all four cases from other jurisdictions cited by the majority^[10] for the principle that no temporal nexus is required involved statutes that, unlike our murder statute, contained no element of intent and have been superseded by fetal homicide statutes, which eliminated the born alive rule and effectively repudiated the legal rationale for its adoption in those jurisdictions.

General Statutes ง 53a-54a(a) provides in relevant part: "A person is guilty of murder when, with intent to cause the death of another person, he causes the death of such person or of a third person...." There can be no clearer expression of a temporal nexus between the intent necessary to commit the crime and the act of committing the crime than this language. The use of the term "when" mandates that the defendant must have the intent to cause the death of a person prior to, or contemporaneously with, the act that is the cause of death.

The statute's reference to the death "of such person or of a third person" further suggests that the unintended victim, as well as the intended victim, must be a person when the fatal injury is inflicted because the term "such person" relates back to the time of the criminal act and is linked with the term "third person" by the word "or." This court previously has stated that, "[a]mong the definitions of the word `or' is `the synonymous, equivalent, or substitutive character of two words or phrases....' Webster's Third New International Dictionary." Seymour v. Seymour, 262 Conn. 107, 112, 809 A.2d 1114 (2002). It is thus very clear that the intended and unintended victims of the defendant's criminal conduct must occupy an equivalent status as persons at the time the injury is inflicted. Indeed, if the victim is not a person when the injury is inflicted, it is hard to understand, without engaging in logical and linguistic acrobatics, how the defendant's conduct can cause the victim's subsequent death. Furthermore, the majority cites no other statute in our Penal Code that lacks the requirement of a temporal nexus between the criminal conduct in question and the status of the victim as a person. Accordingly, the language in the statute clearly instructs that a defendant cannot be found guilty of murder unless the intended and unintended victims are persons when the injuries are inflicted.

The majority's attempt to parse the statutory language by turning to the dictionary definition of the word "when" in support of its assertion that no temporal nexus is required is unavailing. Webster's Third New International Dictionary defines "when" in relevant part as "at or during the time that," which unquestionably establishes that a temporal nexus must exist because the link created between the element of intent and the criminal *115 act by the use of the word "when" necessarily requires that the victim be a person at the time the act is committed, it being self-evident that there can be no intent to kill a person if the law does not recognize that the victim is a person.

The majority also relies on four cases from other jurisdictions. These include Cuellar v. State, 957 S.W.2d 134 (Tex.App. 1997), in which the court stated that "[i]t is not necessary that all of the elements of a criminal offense be immediately satisfied at the time of the defendant's conduct"; id., at 139; and State v. Cotton, 197 Ariz. 584, 588-89, 5 P.3d 918 (App.2000), State v. Hammett, 192 Ga.App. 224, 225, 384 S.E.2d 220 (1989), and Jones v. Commonwealth, 830 S.W.2d 877, 880 (Ky.1992), all of which concluded that it is not the status of the victim at the time of the injury that determines the nature of the crime but the victim's status at the time of death. In all four jurisdictions, however, the statutes in question lacked the element of intent that supplies the requisite temporal link between the criminal conduct and the status of the victim as a person in Connecticut's murder statute. See State v. Cotton, supra, at 586, 5 P.3d 918 (defendant charged under Arizona's second degree murder statute, which provides in relevant part that offense is committed when person "without premeditation ... [and] [u]nder circumstances manifesting extreme indifference to human life ... recklessly engages in conduct which creates a grave risk of death and thereby causes the death of another person," but convicted under Arizona's manslaughter statute, which provides in relevant part that offense is committed by "[r]ecklessly causing the death of another person" [internal quotation marks omitted]), quoting Ariz.Rev.Stat. Ann. งง 13-1104(A)(3) and 13-1103(a)(1) (Cum.Sup.1999); State v. Hammett, supra, at 224, 384 S.E.2d 220 (defendant charged under Georgia's second degree homicide by vehicle statute, which provides in relevant part that "[a]ny person who causes the death of another person, without an intention to do so, by violating [certain] provision[s] of [the Georgia motor vehicle and traffic laws] commits the offense of homicide by vehicle in the second degree when such violation is the cause of said death" [internal quotation marks omitted]),^[11] quoting Ga.Code Ann. ง 40-6-393(b) (1989); Jones v. Commonwealth, supra, at 877 (defendant charged under Kentucky's second degree manslaughter statute, which provides in relevant part that offense is committed when one "wantonly causes the death of another person" [internal quotation marks omitted]), quoting Ky.Rev.Stat. Ann. ง 507.040 (Michie 1985); Cuellar v. State, supra, at 136-37 (defendant charged under Texas' intoxication manslaughter statute, which provides in relevant part that offense is committed when person "[1] operates a motor vehicle in a public place, an aircraft, or a watercraft; and [2] is intoxicated and by reason of that intoxication causes the death of another by accident or mistake" [internal quotation marks omitted]), quoting Tex. Penal Code Ann. ง 49.08(a) (Vernon 1994).

The significance of the element of intent in Connecticut's murder statute, and what distinguishes it from the foregoing statutes, is that it is specific and must exist *116 contemporaneously with the act that causes the victim's death. In other words, the intent to cause the victim's death must exist in the mind of the perpetrator at the moment the fatal injury is inflicted, which cannot occur when the victim is a fetus because a fetus is not a person under Connecticut law. Indeed, I can think of no case in which this or any other court has determined that the specific intent to kill a person can be found to exist after the act is completed. The language of the statutes in the cases on which the majority relies thus does not support the conclusion that a temporal nexus must exist between the criminal conduct and the status of the victims as persons, as the language of the murder statute in the present case does, because the element of intent is lacking and there is no other requirement of a contemporaneous relationship among the elements of each of the crimes enumerated in those statutes.

Furthermore, all four jurisdictions have since enacted fetal homicide or feticide statutes and thus have repudiated the rationale of the born alive rule in order to avoid the legal inconsistencies that inevitably arise when the criminal conduct is severed from the status of the victim as a person at the time of the fatal injury.^[12] See Ariz.Rev.Stat. Ann. งง 13-1102, 13-1103, 13-1104 and 13-1105 (Cum.Sup. 2008); Ga.Code Ann. ง 16-5-80 (2007); Ky.Rev.Stat. Ann. งง 507A.010(c) and 507A.020 through 507A.050 (LexisNexis 2008); Tex. Penal Code Ann. ง 1.07(49) (Vernon Cum. Sup.2009).

The majority also declares that it is "perfectly clear" that no temporal nexus is required because New York's "homicide statutes ... are materially identical to our homicide statutes"; footnote 42 of the majority opinion; and a New York appellate court applied the born alive rule in affirming a conviction under New York's second degree manslaughter statute.^[13] See People v. Hall, 158 App.Div.2d 69, 76, 557 N.Y.S.2d 879, appeal denied, 76 N.Y.2d 940, 564 N.E.2d 679, 563 N.Y.S.2d 69 (1990). I disagree. Although our Penal Code is modeled in part after the New York Penal Law, the New York statute at issue in Hall pertained to second degree reckless manslaughter, not murder, and, therefore, like the statutes at issue in the Arizona, Georgia, Kentucky and Texas cases that involved reckless conduct, the New York statute is distinguishable from Connecticut's murder statute because it lacks the element of intent that must exist when the fatal injury is inflicted. Accordingly, it is not "materially identical" to our murder statute, and Hall cannot assist this court in interpreting ง 53a-54a.

The majority asserts that it is unaware of any authority in support of the view that a temporal nexus is required between the criminal conduct and the victim's status as a person. I find this assertion surprising when there is so much authority to be found. The reason why the overwhelming majority of states have abandoned the born alive rule and adopted fetal homicide laws, and why two other states have enacted laws expressly limiting the definition of a "person" to one who has been born and is alive at the time of the criminal act; see Colo.Rev.Stat. ง 18-3-101(2) (2009) ("`[p]erson,' when referring to the victim *117 of a homicide, means a human being who had been born and was alive at the time of the homicidal act"); Or.Rev.Stat. ง 163.005(3) (2009) ("`[h]uman being' means a person who has been born and was alive at the time of the criminal act"); is that they wished to restore the temporal connection between the criminal conduct and the status of the victim as a person that is necessarily broken when the born alive rule no longer functions as a rule of causation. Indeed, the Supreme Court of Hawaii in State v. Aiwohi, supra, 109 Hawai`i at 115, 123 P.3d 1210, after considering the benefits and flaws of the born alive rule as applied to the prosecution of mothers and third parties who inflict fatal injuries on a fetus, expressly concluded that the more cogent rule is that "the defendant's conduct must occur at a time when the victim is within the class contemplated by the legislature." Id., at 126, 123 P.3d 1210. The majority's assertion as to the lack of other authority regarding the requirement of a temporal nexus is, therefore, without foundation.^[14]

The majority claims that the enactment by other states of fetal homicide statutes that amend the definition of "person" to include an unborn child or fetus "does not exclude from its purview the infliction of injuries on a viable fetus that is born alive and that subsequently dies from those injuries." (Emphasis in original.) Footnote 67 of the majority opinion. The majority thus reasons that "[fetal] homicide statutes broaden the class of victims protected thereunder by redefining that class, an innovation that bears no relevance to the issue of whether our murder statute contains the kind of temporal requirement that [this concurring and dissenting opinion] says it does." (Emphasis added.) Id. The majority then concludes that, "because [the born alive rule] now is viewed by those states [that have abolished it] as unnecessarily underinclusive with respect to the category of victims that it protects... it would make no sense to reject the rule ... without replacing it with a broader rule, namely, one that includes the killing of a fetus." (Emphasis in original.) I agree that, insofar as the born alive rule previously has been recognized in other states, the adoption of fetal homicide statutes in those states constitutes a repudiation, or abandonment, of the rule. Such statutes not only criminalize conduct that causes the death of a fetus, regardless of *118 whether it is born alive, but, to the extent that the rule has lost its meaning as a rule of causation, they also restore the temporal connection between the element of intent and the status of the fetus at the time of the criminal act.^[15] See, e.g., People v. Ford, 221 Ill.App.3d 354, 367, 163 Ill.Dec. 766, 581 N.E.2d 1189 (1991) (expressly acknowledging legislature's rejection of born alive rule in criminalizing acts directed against unborn child), appeal denied, 143 Ill.2d 642, 167 Ill.Dec. 404, 587 N.E.2d 1019 (1992). This court's failure to recognize the born alive rule, however, would not constitute a similar "repudiation" of the rule because it has not heretofore been recognized in this jurisdiction and thus cannot be abandoned.^[16]

The majority claims, to the contrary, that the born alive rule is "well established in the common law of this state...." This claim is without merit. The majority ignores the fact that, even if the born alive rule had been accepted as part of the common law of this state prior to 1969, which I submit it had not, "[a]doption of the [P]enal [C]ode [in 1969]^[17]abrogated our common law of crimes." (Emphasis added.) State v. Ross, 230 Conn. 183, 197, 646 A.2d 1318 (1994), cert. denied, 513 U.S. 1165, 115 S.Ct. 1133, 130 L.Ed.2d 1095 (1995); accord Valeriano v. Bronson, 209 Conn. 75, 92, 546 A.2d 1380 (1988); see also State v. DeJesus, 288 Conn. 418, 515, 953 A.2d 45 (2008) (Katz, J., dissenting) (relying on Valeriano for proposition that Penal Code abrogated common-law rules, and savings clause of code precludes court from readopting them); Commission to Revise the Criminal Statutes, Penal Code Comments, Conn. Gen.Stat. Ann. (West 2007) ง 53a-4, p. 324 (court not "free to fashion substantive offenses" formerly considered common-law crimes but not included in Penal Code because "the [c]ode precludes ... the notion of common law crimes" [emphasis added]). Accordingly, *119 no matter how many pages or how much passion the majority devotes to its common-law analysis, it cannot overcome the very conspicuous and simple fact that such an analysis is irrelevant following this state's adoption of the Penal Code. Nevertheless, because the majority places so much emphasis on the common-law roots of the born alive rule, including a lengthy discussion of legislative history in an attempt to show that the legislature expressly accepted the rule when it enacted Public Acts 2003, No. 03-21 (P.A. 03-21), entitled "An Act Concerning Assault of a Pregnant Woman," approximately five years after the crime in this case was committed, I am compelled to respond because I believe that much of the majority's analysis is either misleading or legally incorrect.

The common law, as distinguished from statutory law, "comprises the body of those principles and rules of action, relating to the government and security of persons and property, which derive their authority solely from usages and customs of immemorial antiquity, or from the judgments and decrees of the courts recognizing, affirming, and enforcing such usages and customs...." Black's Law Dictionary (6th Ed. 1990). This means that, in order to demonstrate that the born alive rule is "well established in the common law of this state," there must be evidence that the rule was a well known usage or custom in the colony or the state of Connecticut, or that reviewing courts have issued judgments and decrees enforcing the rule over the past 200 years. Even giving the majority the benefit of the doubt, I submit that no such evidence exists.

The majority relies on a single treatise, written in 1796 by a former Chief Justice of the Connecticut Supreme Court, Zephaniah Swift,^[18] that explains the born alive rule in the context of the common-law definition of murder, and on three trial court decisions, a single Appellate Court decision, the Model Penal Code and the common-law principles that govern criminal matters in this state. Swift, however, authored the treatise several years before he became a judge of the Superior Court in 1801, and nearly twenty years before he became Chief Justice of this court in 1814. See 2 Z. Swift, A Digest of the Laws of the State of Connecticut (1823), memoir of the author. Swift's treatise thus does not represent his understanding of the decisional law rendered by Connecticut courts during his time on the bench. In addition, others have observed that Swift's treatise "not only covered Connecticut law but encompassed the law `generally.'" Valeriano v. Bronson, supra, 209 Conn. at 91 n. 10, 546 A.2d 1380, citing P. O'Sullivan, "Biographies of Connecticut Judges," 19 Conn. B.J. 181, 192 (1945). Notwithstanding this limitation, the revised version of Swift's treatise, which was published in 1823 before advanced medical technology permitted a determination to be made as to whether a fetus was alive in utero, explains that the reason why the killing of a fetus that dies in utero is not considered murder is because "the circumstance[s] of its death cannot be ascertained with sufficient precision," not because the fetus does not satisfy the definition of a "person."^[19] 2 Z. Swift, supra, at p. 267.

*120 With respect to the three trial court decisions that allegedly recognize the born alive rule, the issues raised in two of those decisions, one of which was published in 1955 before the availability of advanced medical technology, did not involve criminal conduct but, rather, required the court to determine whether a cause of action could be brought against a negligent wrongdoer for injuries inflicted in utero to a viable fetus and a nonviable^[20] fetus. See Simon v. Mullin, 34 Conn.Supp. 139, 147, 380 A.2d 1353 (1977) (nonviable fetus); Tursi v. New England Windsor Co., 19 Conn.Supp. 242, 248, 111 A.2d 14 (1955) (viable fetus). Consequently, neither decision supports the majority's view that the born alive rule is well established in the common law of this state because "[d]iffering objectives and considerations in tort and criminal law foster the development of different principles...." People v. Greer, 79 Ill.2d 103, 115, 37 Ill.Dec. 313, 402 N.E.2d 203 (1980); see W. Prosser & W. Keeton, Torts (5th Ed. 1984) ง 2, pp. 7-9.

This leaves State v. Anonymous (1986-1), 40 Conn.Supp. 498, 516 A.2d 156 (1986) (Anonymous), in which the issue before the court was "whether an unborn but viable fetus is a `human being' within the meaning of the Connecticut statutes defining murder." (Emphasis added.) Id., at 499, 516 A.2d 156. In concluding that such a fetus is not a "human being," the court first examined the legislative history of Connecticut's Penal Code and noted that the murder section was based in part on the revised New York Penal Law and in part on the Model Penal Code; id., at 500, 516 A.2d 156; which define the terms "person" and "human being," respectively, as one "who has been born and is alive." N.Y. Penal Law ง 125.05(1) (McKinney 2009); accord Model Penal Code ง 210.0(1) (1980). The court thus concluded that "[i]t is obvious that neither the word `person' nor the words `human being' would include an unborn fetus under the [revised] New York Penal [Law] or the Model Penal Code." (Emphasis added.) State v. Anonymous (1986-1), supra, at 501, 516 A.2d 156. The court then examined this state's homicide statutes and determined that the Connecticut legislature "did not intend to define a `human being' as an unborn but viable fetus." Id. The court finally observed that, under common-law principles dating back to seventeenth century England, "an unborn fetus," regardless of viability, cannot be the subject of a homicide. Id., at 502, 516 A.2d 156. The court cited nine cases from other jurisdictions in support of this principle, all of which concluded that the killing of a fetus in utero is not a homicide because, under the born alive rule, a fetus is not considered a person. Id., at 503, 516 A.2d 156. In closing, the court noted that "any redefining of the word `person' must be left to the legislature, which has the primary authority to define crimes." Id., at 505, 516 A.2d 156. The court also observed that its decision related only to the crime of murder, and not to tort law, because American courts that have afforded to fetuses "the benefits of tort law" in the civil context have declined to treat the killing of a fetus in utero as a homicide and thus have refused to change the born alive rule in criminal cases, relying on the "[d]iffering objectives and considerations in tort and criminal law...." (Internal quotation marks omitted.) Id., quoting People v. Greer, supra, 79 Ill.2d at 115, 37 Ill.Dec. 313, 402 N.E.2d 203.

*121 Anonymous has little, if any, precedential value in the present context because the issue before the trial court was whether an unborn fetus, rather than a fetus that is fatally injured but is subsequently born alive, is a "human being" under Connecticut's murder statute, and the court specifically stated that any redefinition of the term "person" must be left to the legislature because that body alone has the authority to define crimes. State v. Anonymous (1986-1), supra, 40 Conn. at 505, 516 A.2d 156. Moreover, eight of the nine jurisdictions cited by the court that did not consider the killing of an unborn fetus a homicide have since enacted fetal homicide or feticide statutes and discarded the born alive rule.^[21] Insofar as the court stated that "the codes from which our Connecticut law was drawn limit the words `human being' to those who have been born alive"; id., at 501, 516 A.2d 156; the statement suggests nothing with respect to whether the infliction of a fatal injury on a fetus that is subsequently born alive constitutes murder; rather, it simply means that a human being is one who is born and is alive. Indeed, it is absolutely clear from the discussion that precedes and follows this quoted language that the court was referring only to the killing of an unborn fetus because "Connecticut's legislature did not intend to define a `human being' as an unborn but viable fetus." Id. Although the court also stated in dictum that, under the born alive rule, an unborn fetus is not considered a person; see id., at 503, 516 A.2d 156; its passing reference to the born alive rule incorrectly describes the rule, which did not reject the idea that the killer of an unborn fetus could be prosecuted for murder but merely required evidence that the fetus had been born alive to prove that it was alive when the criminal act was committed. Lastly, the trial court's conclusion that the killing of an unborn fetus is not a homicide did not require the court to adopt the born alive rule because the issue in that case was whether an unborn fetus was a human being under Connecticut's murder statute. Id., at 499, 516 A.2d 156. Thus, the trial court's reasoning in Anonymous hardly supports the majority's assertion that the born alive rule was adopted in that case or that the rule "is well established in the common law of this state," and the majority's attempt to suggest otherwise by also citing to In re Valerie D., 25 Conn.App. 586, 591, 595 A.2d 922 (1991), rev'd on other grounds, 223 Conn. 492, 613 A.2d 748 (1992), which involved the termination of parental rights and quoted certain language from Anonymous, is misguided, at best.^[22]

The majority also seeks support for its view in the Model Penal Code, but its reasoning is internally inconsistent and reflects a misunderstanding of the code. On the one hand, the majority concedes that "it is not entirely clear" whether the Model Penal Code intended the definition of "human being" to apply to a fetus that is born alive but later dies from injuries inflicted in utero. Footnote 35 of the majority *122 opinion. The majority further concedes that "it [is] more likely that the [related] commentary to the Model Penal Code was intended to clarify that the killing of a fetus in utero does not constitute the crime of homicide, and that [the Model Penal Code] definition [of `human being'] does not expressly address the more specific issue of whether it is a homicide when an infant, having been injured in utero, is born alive and then dies of his or her injuries." Id. On the other hand, the majority asserts that, "[b]ecause our statutory scheme is patterned after the Model Penal Code," we must presume that our legislature would have "expressly repudiat[ed]" the born alive rule if it had not intended it to apply.^[23] Id. The majority thus cites the Model Penal Code as authority for adopting the born alive rule in Connecticut after explicitly rejecting the notion that the code was intended to incorporate the rule in defining the term "human being."

Even if the Model Penal Code's definition of "human being" could be construed as an implicit adoption of the born alive rule, which I believe it cannot, the Connecticut legislature declined to embrace that definition or the definition of "person" in the New York Penal Law when it adopted this state's Penal Code in 1969. See General Statutes ง 53a-3(1) (defining "person" for purposes of Penal Code as "a human being, and, where appropriate, a public or private corporation, a limited liability company, an unincorporated association, a partnership, a government or a governmental instrumentality"). Accordingly, even though portions of our Penal Code may be patterned after the Model Penal Code and the legislature may have been familiar with the Model Penal Code commentary, the legislature's decision to reject the definitions of "person" and "human being" in the New York Penal Law and Model Penal Code, respectively, necessarily constitutes a rejection of any affirmative implications regarding the born alive rule purportedly arising therefrom.

The majority next claims that "[t]he born alive rule has deep roots in our common law" and that it knows of "no reason... why the ... rule would not have been accepted as the law of this state ... just as [it] was accepted by virtually every other jurisdiction that had considered it." I agree that the born alive rule is derived from the common law of England and that *123 some of our sister states have accepted the rule in the past. See, e.g., State v. Cotton, 197 Ariz. 584, 589, 5 P.3d 918 (App.2000); Ranger v. State, 249 Ga. 315, 317, 290 S.E.2d 63 (1982); People v. Bolar, 109 Ill.App.3d 384, 389, 64 Ill.Dec. 919, 440 N.E.2d 639 (1982); Jones v. Commonwealth, 830 S.W.2d 877, 880 (Ky.1992); Williams v. State, 316 Md. 677, 682-83, 561 A.2d 216 (1989); State v. Cornelius, 152 Wis.2d 272, 280-82, 448 N.W.2d 434 (App.1989). The majority provides no citations or support, however, for its far broader assertion, presented as established fact, that the rule "has been universally recognized by courts and commentators throughout the country as deeply rooted in the common law"; (emphasis added); thus implying that the born alive rule has been accepted as part of the common law in all other jurisdictions. Indeed, most, if not all, jurisdictions that have rejected the born alive rule appear to have done so statutorily only following the rule's express acceptance by the courts in those jurisdictions, not because the rule inhabited the common law in some ethereal sense without judicial recognition and approval.

In addition, the majority ignores the crucial fact that the precise issue before this court never has been litigated in Connecticut, and, therefore, the rule never has been recognized and adopted in this state, a conclusion absolutely required by the cases on which the majority itself relies.^[24] In fact, in one such case, this court noted in a passage from which the majority selectively quotes that the English common law has not been transplanted automatically into Connecticut's legal soil but, rather, "[h]istorically, our view of the relationship of the common law of England to the law of Connecticut has been conspicuous by its ambivalence. During the greater part of the colonial era, the common law of England was not deemed to form a part of the jurisprudence of Connecticut, except so far as any part of it might have been accepted and introduced by her own authority.... Later this court accepted the doctrine that the English common law was brought here by the first settlers, and became the common law of Connecticut so far as it was not unadapted to the local circumstances of this country.... In more recent years we seemed to have reverted to our earlier colonial thinking by asserting that the common law of England prior to 1776 does not necessarily represent the common law of this state; State v. Muolo, [supra, 118 Conn. at 378, 172 A. 875]; even mutatis mutandis. We further defined our common law in our own terms as the prevailing sense of the more enlightened members of a particular community, expressed through the instrumentality of the courts, as to those rules of conduct which should be definitely affirmed and given effect under the sanction of organized society, in view of the particular circumstances of the time, but with due regard to the necessity that the law should be reasonably certain and hence that its principles have permanency and its development be by an orderly process. Such a definition necessarily implies that the common law must change as circumstances change." (Citations omitted; emphasis added; internal quotation marks omitted.) Dacey v. Connecticut Bar Assn., 184 Conn. 21, 25-26, 441 A.2d 49 (1981).

*124 The majority responds to this clear and unambiguous statement of how Connecticut courts have incorporated the common law of England into this state's legal framework by declaring that I have a "fundamental misapprehension of the manner in which the common law is identified and applied. Even if no court of this state previously had recognized the existence of the born alive rule, we would be required to determine its existence on the basis of the case law of England, the decisions of courts of other jurisdictions, and the works of common-law scholars." Footnote 39 of the majority opinion. The majority thus appears to subscribe to the view that all of the English common law has been assimilated into the common law of this state, regardless of whether it has been recognized either statutorily or by the courts. I emphatically disagree.

In clear disregard of our precedent, the majority ignores significant portions of our analysis in Dacey and relies on the case law of several foreign jurisdictions, including Arkansas, Maryland, Minnesota and North Dakota to guide its common-law analysis. See id. To the extent that the majority acknowledges Dacey, it takes a small passage from Graham v. Walker, 78 Conn. 130, 133, 61 A. 98 (1905), which also is quoted in Dacey, that the English common law "`was brought here by the first settlers, and became the common law of Connecticut so far as it was not unadapted to the local circumstances of this country.'" The majority also quotes selectively from Dacey for the proposition that, at times, our view of the common law of England has been ambivalent and that the common law does not necessarily represent the common law of our state. The majority then concludes that Connecticut has demonstrated no ambivalence with respect to the common-law born alive rule. The majority, however, omits all of the surrounding language in Dacey, in which the court explains that the common law of England "was not deemed to form a part of" Connecticut law during the greater part of our colonial history unless specifically introduced by our state's own authority and that, in recent years, we have "reverted to our earlier colonial thinking by asserting that the common law of England prior to 1776 does not necessarily represent the common law of this state...." (Citations omitted; internal quotation marks omitted.) Dacey v. Connecticut Bar Assn., supra, 184 Conn. at 25, 441 A.2d 49. In other words, the majority distorts the historical analysis in Dacey by quoting out of context language that it deems favorable to its view and by ignoring those portions of Dacey, and the Connecticut cases cited therein, that do not support its view, even though none of the cited cases has been overruled or qualified in the nearly thirty years since Dacey was decided. As a result, the majority's conclusion that the born alive rule is well established in the common law of this state lacks any convincing support because Connecticut courts never have acknowledged and applied it in the criminal context. Consequently, there can be no presumption that they would have done so had the issue been presented. Moreover, even if the born alive rule had been established in the common law of this state, it would have been superseded by our Penal Code, which, as previously discussed, requires that the victim of a murder be a person at the time of the criminal act. In fact, that is exactly what we concluded in Valeriano v. Bronson, supra, 209 Conn. at 90-96, 546 A.2d 1380, a case directly on point, in which we rejected the petitioner's argument that the English common-law year and a day rule,^[25] another rule of causation *125 that applied to prosecutions for homicide, existed in the common law of Connecticut.

In Valeriano, we determined that the common-law year and a day rule had never been adopted in this state and that, even if it had, it had been abrogated by enactment of the comprehensive Penal Code in 1969. Id., at 95-96, 546 A.2d 1380. Relying on reasoning similar to that which I have articulated in this opinion, we stated that (1) passing references to the rule in two prior cases were merely "part of a larger [passage] that addressed the dispositive issue in [those cases]," which had nothing to do with the year and a day rule; id., at 91, 546 A.2d 1380; (2) "discussion in a judicial opinion that goes beyond the facts involved in the issues is mere dictum and does not have the force of precedent"; id.; (3) no other Connecticut decision had expressly "adopted and applied" the year and a day rule; id.; (4) even if the rule had existed in the common law of Connecticut prior to 1969, "adoption of the comprehensive [P]enal [C]ode in 1969 abrogated the common law and set out substantive crimes and defenses in great detail," and, there having been no mention of the year and a day rule in the Penal Code, it had not been adopted; id., at 92, 546 A.2d 1380; (5) the language of the savings clause in General Statutes ง 53a-4^[26] and related commentary by the commission to revise the criminal statutes indicated that the savings clause was intended to apply only to those statutes in the chapter in which ง 53a-4 appears, namely, chapter 951 on statutory construction and principles of criminal liability, and not to the homicide statutes in chapter 952; id., at 93-94, 546 A.2d 1380; (6) the year and a day rule would be "inconsistent" with the homicide statutes because the rule "prevents conviction for a homicide [when] the victim does not die within a year and a day of the defendant's conduct causing the death," and, "given the sweeping overhaul of the criminal law wrought by the [P]enal [C]ode in 1969, it is wholly illogical that such a defense in bar not be specifically included in the code or ... chapter [951] which is rife with `defenses' ... [p]articularly... where the crime of homicide is involved"; id., at 94, 546 A.2d 1380; (7) the "original reason for the year and a day rule developed hundreds of years ago when medical science was hardly as advanced as it [was in the 1980s]," and that reason no longer exists because it is now possible to diagnose with far greater precision the cause of the victim's death, and, therefore, "the policy behind the rule is dubious ... in the twentieth century"; (internal quotation marks omitted) id., at 94-95, 546 A.2d 1380; (8) the rule was "in decline throughout the United States" and numerous jurisdictions already had abolished it; id., at 95, 546 A.2d 1380; and (9) although Swift's Digest of the Laws of the State of Connecticut specifically refers to the year and a day rule, Swift did not state that the rule was part of Connecticut's common law as opposed to the English common law in general, and "[i]t must be *126 remembered that Swift's Digest not only covered Connecticut law but encompassed the law `generally,'" and, "[u]nder the circumstances, any reliance on Swift would have been a weak position."^[27] Id., at 91-92 n. 10, 546 A.2d 1380.

I submit that Valeriano must serve as precedent in determining whether the born alive rule is embedded in the common law of this state because the born alive rule, like the year and a day rule, was a common-law rule of causation applied by English courts to determine liability in homicide cases. Accordingly, all of the reasons on which this court relied in rejecting the argument that the year and a day rule existed in Connecticut apply with equal force to the born alive rule. These include that (1) no Connecticut court expressly has concluded that the infliction of injuries to a fetus that is born alive but that subsequently dies from those injuries constitutes murder, (2) to the extent that the Superior Court and the Appellate Court referred to the rule in Anonymous and In re Valerie D., respectively, it was mentioned only in passing as part of a *127 larger discussion of the dispositive issues in those cases, none of which had anything to do with the infliction of fatal injuries on a fetus that is subsequently born alive, and, thus, those references were merely dicta with no precedential value, (3) there is no support for the rule in Swift's Digest because Swift never suggested that the rule had been adopted in Connecticut, (4) even if it is assumed that the born alive rule existed in our common law, enactment of our Penal Code abrogated the rule, and it is not preserved by the savings clause, which does not apply to chapter 952 of the General Statutes, in which the murder and capital felony statutes appear, (5) the rule is inconsistent with our homicide statutes because the legislature specifically rejected any modification of the term "person" to include a viable fetus when it rejected the proposed fetal homicide bill; see Raised House Bill No. 5747 (2002); and (6) advanced medical technology has rendered the original reason for the born alive rule, as in the case of the year and a day rule, obsolete.

The majority nonetheless claims that "[c]ourts in other jurisdictions have ... consistently concluded that the death of an infant who is born alive from injuries inflicted in utero constitutes homicide." (Internal quotation marks omitted.) Such a comparison, which might have been compelling forty or fifty years ago, is now passe'. See State v. Lamy, supra, 158 N.H. at 521, 969 A.2d 451 (describing born alive rule as "outdated anachronism often producing anomalous results"). Most other jurisdictions that have adopted the born alive rule did so at a time in our nation's history when the health of the fetus could not be monitored in utero, which is no longer the case. Although the majority concedes that "recent advances in medical science have prompted a number of state courts to depart from the born alive rule" in favor of a rule recognizing that a fetus can be the victim of a homicide, it fails to acknowledge that the "recent trend" to which it refers is more akin to a landslide, with approximately 70 percent of our sister states now rejecting the born alive rule in favor of fetal homicide laws. Indeed, many, if not most, of the cases from other jurisdictions that had adopted the born alive rule and on which the majority relies have been superseded by the fetal homicide laws enacted in those jurisdictions.^[28] See, e.g., State v. Cotton, supra, 197 Ariz. at 589, 5 P.3d 918 (born alive rule superseded by Ariz.Rev.Stat. Ann. งง 13-1102, 13-1103, 13-1104 and 13-1105 [Cum. Sup.2008]); Ranger v. State, supra, 249 Ga. at 317, 290 S.E.2d 63 (born alive rule superseded by Ga.Code Ann. ง 16-5-80 [2007]); People v. Bolar, supra, 109 Ill. App.3d at 389, 64 Ill.Dec. 919, 440 N.E.2d 639 (born alive rule superseded by 720 Ill. Comp. Stat. Ann. 5/9-1.2, 5/9-2.1 and 5/9-3.2 *128 [West 2002]); Jones v. Commonwealth, supra, 830 S.W.2d at 880 (born alive rule superseded by Ky.Rev.Stat. Ann. งง 507A.010[1][c] and 507A.020 through 507A.050 [LexisNexis 2008]); Williams v. State, supra, 316 Md. at 682-83, 561 A.2d 216 (born alive rule superseded by Md.Code Ann., Crim. Law ง 2-103 [LexisNexis Sup.2009]); State v. Cornelius, supra, 152 Wis.2d at 280-82, 448 N.W.2d 434 (born alive rule superseded by Wis. Stat. Ann. ง 940.04 [West 2005]). In short, there is no evidence that the born alive rule is "well established in the common law of this state," and the overwhelming majority of our sister states do not continue to follow the rule. Consequently, the majority's conclusion to the contrary lacks any solid basis in fact and is inconsistent with Valeriano.

The majority further justifies its decision on the ground that the legislative history of P.A. 03-21 (aggravated assault statute)^[29] "reflects the legislature's express acceptance of the [born alive] rule" because the legislature rejected a bill^[30] that would have defined "person," for purposes of the Penal Code, to include a viable fetus and enacted the aggravated assault statute in its place. This conclusion is both logically flawed and completely unsupported by the legislative history. There is no reflection in the legislative history of the legislature's express acceptance of the born alive rule, and nowhere in the legislative history does any legislator suggest that the rule is part of the common law of this state. Moreover, it is wholly irrelevant what assumptions the legislature made regarding the born alive rule because the statute was enacted nearly five years after the crime in this case was committed, and, in any event, the common law is not determined by legislative assumptions as to what the common law may be.

The majority states,^[31] and I agree, that enactment of the fetal homicide bill would have constituted legislative rejection of the born alive rule, if it had been part of the common law, because treating the killing of a fetus in utero as a homicide without evidence that the fetus was alive at the time of the criminal act plainly conflicts with the rule's requirement that such evidence be provided in order for such a killing to constitute a homicide. The legislature's decision to treat the assault of a pregnant woman that results in the termination of her pregnancy as an aggravated assault, however, is not synonymous with acceptance of the born alive rule. To the contrary, the legislature consciously declined to address statutorily the controversial issue of the status of the fetus by omitting any reference to the unborn child in the aggravated assault statute and by making the offense a crime against the *129 pregnant woman rather than against the fetus. The reason why the legislature took this approach was that it wanted to punish conduct resulting in the termination of a pregnancy without becoming embroiled in an abortion rights debate and without granting the fetus independent legal recognition, which would have been granted under the fetal homicide bill. In other words, the aggravated assault statute was not intended to punish the perpetrator for a crime against the fetus but to provide pregnant women with additional protections by increasing the existing penalty for the assault of a pregnant woman if the assault results in the termination of her pregnancy. Compare P.A. 03-21 (designating assault of pregnant woman that results in termination of her pregnancy as class A felony) with General Statutes ง 53a-59a (designating assault of pregnant woman in first degree as class B felony). Although this may appear to be a distinction without a difference, it was crucial to the enactment of the aggravated assault statute. The point is that, because the aggravated assault statute did not grant the fetus legal recognition, the statute is inconsistent with the presumption of the born alive rule that a fetus is a person as long as there is evidence that it was born alive. Accordingly, the majority's attempt to treat the legislature's refusal to expand the definition of "person" to include a fatally injured fetus as an affirmation of the born alive rule must collapse under the weight of its own faulty logic.

The majority further declares that "it is abundantly clear that ... the legislature fully considered and rejected the possibility of abolishing the born alive rule and adopting a viability rule instead." This assertion is wrong in at least two respects. First, it implies that the born alive rule is presently followed in Connecticut because "the legislature ... rejected the possibility of abolishing" it. As previously stated, I disagree that such a conclusion can be drawn from an objective examination of this state's common law or the legislative history of the aggravated assault statute. Second, it suggests that the legislature expressly considered the possibility of eliminating the born alive rule when it enacted the aggravated assault statute, when in fact it did not.

The only references to the born alive rule during the legislative proceedings on the fetal homicide and aggravated assault bills were made by Clarke D. Forsythe, president of Americans United for Life, and Bill O'Brien, legislative vice president of Connecticut Right to Life Corporation. Both Forsythe and O'Brien remarked in passing that that the definition of "person" in the Penal Code should be expanded to include an unborn fetus because the born alive rule had become outmoded and should be abolished in Connecticut. See Conn. Joint Standing Committee Hearings, Judiciary, Pt. 2, 2003 Sess., p. 424, remarks of O'Brien; id., at pp. 663-66, written testimony of Forsythe; Conn. Joint Standing Committee Hearings, Judiciary, Pt. 8, 2002 Sess., pp. 2403-2404, remarks of Forsythe. Forsythe admitted, however, that he was a resident of Illinois and twice explained that he was "not familiar with" or "aware of the intricacies of Connecticut law...." Conn. Joint Standing Committee Hearings, Judiciary, Pt. 8, 2002 Sess., pp. 2406, 2407. Moreover, no member of the committee or General Assembly referred to the born alive rule during the public hearings or legislative debates on the matter. The legislature understandably was concerned with the much narrower question of whether and how to penalize a perpetrator for causing the death of an unborn fetus. Furthermore, any positive discussion of the born alive rule would have been inconsistent with the legislature's express unwillingness *130 to create a new capital offense. See id. at pp. 2429-30, remarks of Representative Michael P. Lawlor (stating that creation of "new capital offense" was "real issue" and that he was "extremely reluctant" to expose potential defendants to capital punishment for killing unborn fetus). Accordingly, because the record demonstrates that the legislature did not discuss, or take any action that could be construed as recognizing, the born alive rule at any time during the proceedings, it cannot be said that the legislature "fully considered and rejected" abolishing the born alive rule in Connecticut.^[32]
