Schneiderman v. United States, 320 U.S. 118 (1943), was a U.S. Supreme Court case involving denaturalization. By a 5–3 vote, the justices rejected the federal government's attempt to denaturalize William Schneiderman, a self-avowed communist. The Court held that "clear, unequivocal, and convincing" proof was required to revoke citizenship; it determined that there was insufficient evidence that Schneiderman was not "attached to the principles of the Constitution" as required by federal law.
