Cohens v. Virginia, 19 U.S. (6 Wheat.) 264 (1821), is a landmark case by the Supreme Court of the United States that asserts the Court's power to review state supreme court decisions in criminal law matters if defendants claim that their constitutional rights have been violated. The Court had previously asserted a similar jurisdiction over civil cases involving U.S. parties (see Martin v. Hunter's Lessee).
The defendants were members of a prominent Baltimore banking family. A U.S. senator and two U.S. representatives served as attorneys for the opposing sides. The two defendants, Mendes I. Cohen and Philip I. Cohen, would later rise to the positions of U.S. Army Colonel and Maryland Delegate (Mendes), and U.S. Postmaster (Philip).
