With the Judiciary Act of 17891, "the judicial power of the United States, shall be vested in one Supreme Court,
and in such inferior courts as the Congress may from time to time ordain and
establish."2 The federal court system is still shaped by the basic concepts of that statute, although the Circuit Courts have been abolished and the Court of Appeals have taken over the intermediate appellate jurisdiction, which they exercised and have been vested, in addition, with a much larger appellate jurisdiction, and the jurisdiction of the District Courts has been greatly enlarged.3
