Trop v. Dulles

Case Date: 05/04/2025

Trop v. Dulles, 356 U.S. 86 (1958), was a federal case in the United States in which the Supreme Court ruled, 5-4, that it was unconstitutional for the government to revoke the citizenship of a U.S. citizen as a punishment. The ruling's reference to "evolving standards of decency" is frequently cited precedent in the court's interpretation of the Eighth Amendment's prohibition on "cruel and unusual punishment."
