CCP 1102. The writ of prohibition arrests the proceedings of any tribunal, corporation, board, or person exercising judicial functions, when such proceedings are without or in excess of the jurisdiction of such tribunal, corporation, board, or person.
CCP 1103. (a) A writ of prohibition may be issued by any court, except municipal courts, to an inferior tribunal or to a corporation, board, or person, in all cases where there is not a plain, speedy, and adequate remedy in the ordinary course of law. It is issued upon the verified petition of the person beneficially interested.
(b) The appellate division of the superior court may grant a writ of prohibition directed to the superior court in a limited civil case or in a misdemeanor or infraction case. Where the appellate division grants a writ of review directed to the superior court, the superior court is an inferior tribunal for purposes of this chapter.
