corrections law overview
Correctional institutions are the places where convicted criminals serve out their sentences, including prisons, halfway houses and supervised release programs. They are generally of statutory creation and are governed by boards of charities and corrections, or similar boards that are part of a branch of municipal or state government. State and local legislatures that control corrections law are limited only by the Constitution.
Federal penal and correctional institutions, except for naval and military institutions, are controlled by the Attorney General. The Bureau of Prisons is under the Attorney General, and manages and regulates all aspects of federal penal and correctional facilities.
