The Communist Control Act (68 Stat. 775, 50 U.S.C. 841-844) is an American law signed by President Dwight Eisenhower on 24 August 1954, which outlaws the Communist Party of the United States and criminalizes membership in, or support for the Party or "Communist-action" organizations and defines evidence to be considered by a jury in determining participation in the activities, planning, actions, objectives, or purposes of such organizations.[1] The Act has since been ruled unconstitutional in federal court but has not been ruled on in the Supreme Court and has never been enforced.
