Organization

The federal court system is made up of constitutional and legislative courts.

Federal district courts, courts of appeals, and the Supreme Court are constitutional courts. These are constitutional courts because Article III of the Constitution either established them or authorized Congress to establish them.

Legislative courts are set up by Congress under its implied powers, usually for special purposes. For example, the U.S Court of Appeals for Veterans Claims is a legislative court. The judges who preside over these federal courts are appointed by the president.
