Headnotes

  1. Constitutional Law — Federal Supremacy Where Congress has not expressly stated whether a federal statute has occupied a field in which the States are otherwise free to legislate, no single formula governs; supersession is determined by applying several criteria, including whether the federal scheme of regulation is so pervasive as to support the inference that Congress left no room for the States to supplement it, whether the federal interest in the field is so dominant that the federal system must be assumed to preclude enforcement of state laws on the same subject, and whether enforcement of state law presents a serious danger of conflict with the administration of the federal program. 350 U.S. at 501–505
  2. Constitutional Law — Supremacy Clause The Smith Act, as amended, and the related federal antisubversive statutes — the Internal Security Act of 1950 and the Communist Control Act of 1954 — together establish a scheme of federal regulation so pervasive as to make reasonable the inference that Congress intended to occupy the field of sedition, leaving no room for the States to supplement it by enforcing their own sedition statutes. 350 U.S. at 502–504
  3. Constitutional Law — Supremacy Clause The federal antisubversive statutes touch a field in which the federal interest is so dominant that the federal system must be assumed to preclude enforcement of state laws on the same subject, because Congress has treated seditious conduct as a matter of vital national concern and has devised an all-embracing program for resisting totalitarian aggression. 350 U.S. at 504–505
  4. Constitutional Law — Supremacy Clause Enforcement of state sedition laws presents a serious danger of conflict with the administration of the federal program, because since 1939 the Federal Government has sought to avoid sporadic local prosecutions by urging local authorities to turn information concerning subversive activities over to the federal authorities, and because state statutes are neither uniform nor equipped with the same substantive and procedural safeguards as the federal law. 350 U.S. at 505–509
  5. Constitutional Law — Supremacy Clause Where Congress has occupied the field to the exclusion of parallel state legislation and the dominant federal interest precludes state intervention, a state sedition statute that proscribes the same conduct as the Smith Act is superseded and unenforceable, regardless of whether it purports to supplement the federal law, because when Congress has taken a particular subject matter in hand, coincidence is as ineffective as opposition, and a state law is not to be declared a help because it attempts to go farther than Congress has seen fit to go. 350 U.S. at 504, 509
  6. Constitutional Law — Federal Supremacy A state sedition law may be enforced at times when the Federal Government has not occupied the field and is not protecting the entire country from seditious conduct; a State may also prosecuting where the same act constitutes both a federal and a state offense under its police power in a field in which the state statute does not impinge on federal jurisdiction, and it may protect itself at any time against sabotage or attempted violence of all kinds. 350 U.S. at 500–501
