In law, the judiciary or judicial system is the system of courts which administer justice in the name of the sovereign or state, a mechanism for the resolution of disputes.
The term is also used to refer collectively to the judges, magistrates and other adjudicators who form the core of a judiciary, as well as the support personnel who keep the system running smoothly. Under the doctrine of the separation of powers, 'the judiciary is the branch of government primarily responsible for interpreting the law'. It construes the laws enacted by the legislature.
