On June 11, 1984 in the case of Nix v. Williams, the Supreme Court adopted a further exception to the exclusionary rule, the "inevitable discovery" doctrine. The inevitable discovery doctrine permits the admission of evidence obtained in spite of a violation of a defendant's constitutional rights, where the prosecution can convince the trier of fact by a preponderance that this evidence would have been discovered regardless of any such violation.
