America's Court System
Federal Court
The jurisdiction of the federal courts is defined in Article III, Section 2, of the Constitution, as extending in law and equity to all cases arising under the Constitution and federal legislation; to controversies to which the U.S. shall be a party, including those arising from treaties with other governments; to admiralty and maritime cases; to controversies between states; to controversies between a state, or its citizens, and foreign governments or their subjects; and to controversies between the citizens of one state and citizens of another state. The federal courts were also originally invested with jurisdiction over controversies between citizens of one state and the government of another state; the 11th Amendment (ratified February 7, 1795), however, removed from federal jurisdiction those cases in which the citizens of one state were plaintiffs and the government of another state was the defendant.

A district court functions in each of the more than 90 federal judicial districts and in the District of Columbia. A court of appeals functions in each of the 11 federal judicial circuits and in the District of Columbia; there is also a more specialized court with nationwide jurisdiction known as the court of appeals for the federal circuit.

All lower federal courts operate under uniform rules of procedure promulgated by the Supreme Court.
