The Jervis Bay Territory is an internal territory of the Commonwealth of Australia, surrendered by the state of New South Wales in 1915 to the Commonwealth Government   so that the landlocked Australian Capital Territory would have maritime access.  Due to the terms of the Jervis Bay Territory Acceptance Act, the laws of the ACT apply to the Jervis Bay Territory,  and it was administered by the Department of the Interior (and later by the Department of the Capital Territory) as if it were part of the Australian Capital Territory, although it has always been a separate Commonwealth territory. In 1989, when the ACT achieved self-government, the Department of the Arts, Sport, the Environment, Tourism and Territories took over responsibility for the JBT's administration, and it has since been administered by various Commonwealth departments responsible to the Minister for Territories.

The seat of the U.S. federal government in Washington is located in a federal district called the District of Columbia. Other federally administered areas that are within one of the 50 states, but not under its jurisdiction, are called federal enclaves.
Additionally, the U.S. federal court system divides each state, the District of Columbia, and Puerto Rico into one or more federal judicial districts. A United States district court and a bankruptcy court are located in each. There are also regional federal judicial circuits, each consisting of a group of states (except for the District of Columbia Circuit, which consists of the federal district, and the Federal Circuit, whose jurisdiction is based on specific subject matter instead of geography); Puerto Rico and the United States territorial courts are also assigned to circuits. Each circuit has a United States court of appeals.
