About: Murphy v. Waterfront Commission

Murphy v. Waterfront Commission of New York Harbor, 378 U.S. 52 (1964), was a United States Supreme Court case concerning the self-incrimination clause in the Fifth Amendment to the United States Constitution. The Court ruled that a state cannot compel a witness to provide testimony that may be incriminating under other State/Federal laws, even if it granted immunity under its own laws. Decided on the same day as Malloy v. Hogan (1964), the Supreme Court reconsidered its previous rulings that the Federal Government could compel witness testimony that could be incriminating under a state's laws, and states could similarly compel testimony that would be incriminating under Federal law.
