In re Debs, 158 U.S. 564 (1895), was a labor law case of the United States Supreme Court, which upheld a contempt of court conviction against Eugene V. Debs. Debs had the American Railway Union continue its 1894 Pullman Strike in violation of a federal injunction ordering labor unions back to work. The Supreme Court held that the federal government's Postal and Commerce Clause authority includes the ability to regulate the labor conditions of railways.
