Constables in the United States
While Constables primarily serve the Courts, they belong to the executive branch of government.
Politics of France
The independent judiciary is based upon civil law system which evolved from the Napoleonic codes. It is divided into the judicial branch (dealing with civil law and criminal law) and the administrative branch (dealing with appeals against executive decisions), each with their own independent supreme court of appeal: the Court of Cassation for the judicial courts and the "Conseil d'Etat" for the administrative courts. The French government includes various bodies that check abuses of power and independent agencies.
