A court created by the Courts Act 1971 to take over the jurisdiction formerly exercised by assizes and quarter sessions, which were abolished by the same Act. It is part of the Supreme Court of Judicature. The Crown Court has an unlimited jurisdiction over all criminal cases tried on indictment and also acts as a court for the hearing of appeals from magistrates' courts. Unlike the courts it replaced, the Crown Court is one court that can sit at any centre in England and Wales designated by the Lord Chancellor. See also three-tier system.
