United States v. Matlock

Case Date: 07/22/1974

United States v. Matlock, 415 U.S. 164 (1974) was a Supreme Court of the United States case in which the Court ruled that the Fourth Amendment prohibition on unreasonable searches and seizures was not violated when the police obtained voluntary consent from a third party who possessed common authority over the premises sought to be searched. The ruling of the court established the "co-occupant consent rule," which was later explained by Illinois v. Rodriguez, 497 U.S. 177 (1990) and distinguished by Georgia v. Randolph (2006), in which the court held that a third party could not consent over the objections of a present co-occupant.
