U.S. Term Limits, Inc. v. Thornton, 514 U.S. 779 (1995), is a landmark U.S. Supreme Court decision in which the Court ruled that states cannot impose qualifications for prospective members of the U.S. Congress stricter than those the Constitution specifies. The decision invalidated 23 states' Congressional term limit provisions. The parties to the case were U.S. Term Limits, a nonprofit advocacy group, and Arkansas politician Ray Thornton, among others.
