The three primary divisions of federal courts are trial courts (94 District Courts), intermediate appellate courts (13 Courts of Appeals), and the United States Supreme Court (the court of final review).
Cases involving the U.S. government, the Constitution, federal legislation, disagreements between states, or disputes between the U.S. government and other governments are all subject to federal court jurisdiction.
