Constables in the United States
While Constables primarily serve the Courts, they belong to the executive branch of government.
Courts of the Republic of Ireland
The Supreme Court, the Court of Appeal, and the High Court are the only courts specifically required by the Constitution. Other courts are established by law. Beneath the superior courts are the Circuit Court and the District Court. The Circuit Court deals with matters that must be tried before a jury. The District Court deals only with minor matters that may be tried summarily.
