89 4- Separation of judicial bodies To ensure soundness of judicial performance, each judicial body is tasked an independent function other than those assigned to the other bodies. While the sitting judge issues judgment, the Public Prosecution conducts investigation and institute lawsuits, the Litigation Department defends the State in suits filed by or against it since the legal system does not recognize that the State is immune against prosecution except in areas of state sovereignty. The People's Law Office defends individuals on the basis of gratuity of defence whether for those who are unable or able, a system that is applicable nowhere in any country in the world. - Multiplicity of litigation degrees It is considered one of the underlying principles in the Libyan judicial system. The lawsuit is instituted before the Court of First Instance; the convict may then challenge its judgment before the Court of Appeal to which the dispute is brought anew for decision by final judgment which may be contested still before the Supreme Court. The mission of this Court is to monitor enforcement and interpretation of the law, as well as soundness of litigation procedures. Its rulings are unimpeachable. Its principles are binding to all courts and administrative bodies. 6- Magistrate Judge and Multiplicity of Judges The Libyan legislator adopts the magistrate judge system for summary courts whereas the multiplicity of judges system is applicable to inclusive circuits in the Courts of First Instance as well as to Appellate Court in examining challenges against judgments issued by Summary Courts in order to ensure transparency and guarantee that the case was examined by more than one magistrate judge. This is also the case with the Courts of Appeal and the Supreme Court.
