Her Majesty's Courts of Justice of England and Wales are the civil and criminal courts responsible for the administration of justice in England and Wales; they apply the law of England and Wales and are established under Acts of the Parliament of the United Kingdom. The United Kingdom does not have a single unified legal system—England and Wales have one system, Scotland another, and Northern Ireland a third. The Court of Appeal, the High Court, the Crown Court, the Magistrates' Courts, and the County Courts are administered by Her Majesty's Courts Service, an executive agency of the Ministry of Justice.
