Whether 18 U.S.C. § 3501 -- read together with Fed. R. Crim. P. Rule 5(a), McNabb v. United States, 318 U.S. 332 (1943), and Mallory v. United States, 354 U.S. 449 (1957) -- requires that a confession taken more than six hours after arrest and before presentment be suppressed if there was unreasonable or unnecessary delay in bringing the defendant before the magistrate judge. Several United States Courts of Appeals have addressed this issue and have issued conflicting decisions, and the panel in this case was split two to one on the issue. This Court granted certiorari to consider the issue in United States v. Alvarez-Sanchez, 511 U.S. 350 (1994), but then resolved the case on a separate "threshold" ground and expressly left open "the subtle questions of statutory construction concerning the safe harbor set out in § 3501(c)." Id. at 356.Question:
Does 18 U.S.C. Section 3501 supplant Supreme Court precedent and make admissible voluntary confessions that are taken more than six hours after arrest and before that person has been presented before judicial officers?
