What branch of government do the courts belong to?
Judiciary
The term "judiciary" is also used to refer collectively to the personnel, such as judges, magistrates and other adjudicators, who form the core of a judiciary (sometimes referred to as a "bench"), as well as the staffs who keep the system running smoothly. In some countries and jurisdictions, judiciary branch is expanded to include additional public legal professionals and institutions such as prosecutors, state lawyers, ombudsmen, public notaries, judicial police service and legal aid officers. These institutions are sometimes governed by the same judicial administration that governs courts, and in some cases the administration of the judicial branch is also the administering authority for private legal professions such as lawyers and private "notary" offices.
