Constables in the United States
While Constables primarily serve the Courts, they belong to the executive branch of government.
Council of State
A Council of State is a governmental body in a country, or a subdivision of a country, with a function that varies by jurisdiction. It may be the formal name for the cabinet or it may refer to a non-executives advisory body associated with a head of state. In some countries it also has a function as a supreme administrative court and sometimes regarded as the equivalent of a privy council.
