Federal prison
A federal prison is operated under the jurisdiction of a federal government as opposed to a state or provincial body. Federal prisons are used for people who violated federal law, people considered dangerous, or those sentenced to longer terms of imprisonment. Not all federated countries have a legal concept of "federal prison".
Australia
The Australian federal government directly controls only a few detention facilities. These include: the Defence Force Correctional Establishment, immigration detention facilities and, in some territories, holding cells at Australian Federal Police stations.While the vast majority of criminal prosecutions in Australia take place in state or territory court systems under state or territory law, there are cases in federal courts, under federal law, that require the imprisonment or remanding of individuals. Unlike other countries with federal systems of government, however, the Constitution of Australia explicitly requires state and territory governments to reserve room in their prison systems for federal prisoners. According to Section 120 of the Constitution: "Every State shall make provision for the detention in its prisons of persons accused or convicted of offences against the laws of the Commonwealth, and for the punishment of persons convicted of such offences, and the Parliament of the Commonwealth may make laws to give effect to this provision." Accordingly, civilians who have, in a federal court, been sentenced to imprisonment or remanded in custody, are detained in state or territory prison, under arrangements with state and territory governments.
