Muehler v. Mena, 544 U.S. 93 (2005), was a unanimous decision by the United States Supreme Court, which held that the Fourth Amendment to the United States Constitution allows detention of an occupant in handcuffs while a search is being conducted, and that it does not require officers to have an independent reasonable suspicion before questioning a subject about their immigration status.
