How later courts describe this case

  • holding that diversity jurisdiction is assessed as of the time at which the suit is filed
  • holding that later addition of nondiverse plaintiff did not destroy diversity jurisdiction if it was present when action was commenced
  • holding that substitution of non-diverse defendant under Rule 25 did not destroy diversity jurisdiction
  • noting that “[w]e have consistently held that if jurisdiction exists at the time an action is commenced, such jurisdiction may not be divested by subsequent events”
  • stating that in a removed case, “it is clear the relevant time period for determining the existence of complete diversity is the time of the filing of the complaint” in state court
  • using this reasoning to support the rule that diversity jurisdiction, once established, is not defeated by the addition of a non-diverse party
  • “[N]othing in Carden suggests any change in the well-established rule that diversity of citizenship is assessed at the time the action is filed.”
  • noting the Supreme Court has “consistently held that if jurisdiction exists at the time an action is commenced, such jurisdiction may not be divested by subsequent events”

Headnotes

  1. Civil Procedure — Diversity Jurisdiction Diversity jurisdiction is determined as of the time an action is commenced; if jurisdiction exists at that time, it may not be divested by subsequent events, including the later addition of a nondiverse party to the action. 498 U.S. 426, 428
  2. Civil Procedure — Diversity Jurisdiction The addition of a nondiverse party after a diversity action has commenced does not defeat jurisdiction that was properly established at the outset, and such a rule is not required to serve the purposes of diversity jurisdiction; a contrary rule could deter normal business transactions during the pendency of what might be lengthy litigation. 498 U.S. 426, 428-429
  3. Civil Procedure — Diversity Jurisdiction Carden v. Arkoma Associates, which addressed whether the citizenship of limited partners must be considered in determining diversity jurisdiction in an action brought by a limited partnership, does not alter the rule that diversity of citizenship is assessed at the time the action is filed. 498 U.S. 426, 428
  4. Civil Procedure — Diversity Jurisdiction Owen Equipment & Erection Co. v. Kroger, holding that a district court's ancillary jurisdiction did not extend to a claim by an original plaintiff against a nondiverse third-party defendant impleaded by the original defendant, does not disturb the principle that diversity jurisdiction is assessed at the time the lawsuit is commenced. 498 U.S. 426, 429
