A Miranda Warning is an explanation of rights given in the United States by a police officer to a suspect before questioning. The suspect must be informed of his or her right to remain silent, to consult with a lawyer and have the lawyer present during questioning, as well as the right to a court-appointed attorney if the suspect cannot afford his or her own. The suspect must clearly state their understanding before an interrogation can take place.
The name "Miranda warning" comes from the case Miranda v. Arizona, with the judgement given on June 13, 1966. In the case, an accused confessed to certain crimes during police interrogation, but the conviction was overturned on appeal when he claimed the police had used intimidating tactics during his questioning. The Miranda warning protects both the rights of the accused and the validity of any subsequent legal proceedings.
