Dickerson v. United States,
530 U.S. 428 (2000)
In the wake of Miranda v. Arizona, in which the Court held that certain warnings must be given before a suspect's statement made during custodial interrogation could be admitted in evidence, Congress enacted 18 U. S. C. §3501, which in essence makes the admissibility of such statements turn solely on whether they were made voluntarily. Petitioner, under indictment for bank robbery and related federal crimes, moved to suppress a statement he had made to the Federal Bureau of Investigation, on the ground he had not received "Miranda warnings" before being interrogated. The District Court granted his motion, and the Government took an interlocutory appeal. In reversing, the Fourth Circuit acknowledged that petitioner had not received Miranda warnings, but held that §3501 was satisfied because his statement was voluntary. It concluded that Miranda was not a constitutional holding, and that, therefore, Congress could by statute have the final say on the admissibility question.
Held: Miranda and its progeny in this Court govern the admissibility of statements made during custodial interrogation in both state and federal courts.
