A 1995 U.S. Supreme Court opinion in which the Court held that states could not place additional qualifications/conditions on membership to the U.S. Congress.
The case involved the constitutionality of an amendment to the Arkansas state constitution which, among other things, prohibited individuals from being listed on the ballot after serving three terms in the House of Representatives or two in the Senate. The Court declared this amendment unconstitutional by ruling that the U.S. Constitution was the only controlling document that specified the qualifications for election to the House and the Senate and individual states could not place term limits for members of the U.S. Congress.
