Constables in the United States
While Constables primarily serve the Courts, they belong to the executive branch of government.
Crown Court
The Crown Court of England and Wales is, together with the High Court of Justice and the Court of Appeal, one of the constituent parts of the Senior Courts of England and Wales. It is the highest court of first instance in criminal cases; however, for some purposes the Crown Court is hierarchically subordinate to the High Court and its Divisional Courts.
