Dickerson v. United States

Dickerson (defendant) sought to suppress incriminating statements made during an FBI interrogation without proper Miranda warnings, but the trial court and court of appeals ruled the statements admissible anyway under 18 U.S.C. § 3501 — a statute Congress passed two years after Miranda specifically allowing voluntary statements to be admitted regardless of Miranda compliance — reasoning that Miranda was not itself a constitutional holding and that Congress could therefore supersede it through ordinary legislation.
