Miranda v. Arizona

Summary

Miranda v. Arizona, 384 U.S. 436 (1966), is a landmark decision of the U.S. Supreme Court in which the Court ruled that law enforcement must warn a person of their constitutional rights before interrogating them when they are in custody, or else the person's statements cannot be used as evidence against them at their trial. Specifically, the Court held that under the Fifth Amendment to the U.S. Constitution, the government cannot use a person's statements made in response to an interrogation while in police custody as evidence at the person's criminal trial unless they can show that the person was informed of the right to consult with a lawyer before and during questioning, and of the right against self-incrimination before police questioning, and that the defendant not only understood these rights but also voluntarily waived them before answering questions.
