U.S. District Court, D.C., August 31, 1995; modified September 15, 1995.This action involved a constitutional challenge to the 147-year-old extradition statute, 18 U.S.C. §3184, on die ground that it violates the separation of powers. Plaintiffs were two individuals who had been found extraditable to Canada, pursuant to the extradition treaty between die United States and Canada, by a U.S. magistrate judge in the Northern District of Illinois. They brought an action in the District of Columbia against the Secretary of State, the Department of State, and the United States for a judgment declaring the extradition statute unconstitutional, and an injunction against their extradition. Plaintiffs also sought certification of a class consisting of persons who are or will be under threat of extradition from the United States pursuant to the statute, and an injunction against any such extradition. The court held (per Lamberth, J.) that (1) the extradition statute violates the separation of powers and is therefore unconstitutional; (2) the United States is enjoined from taking any further act toward the surrender of the plaintiffs to Canada; and (3) the proposed class is certified, and the United States is enjoined from surrendering anyone under the statute.
