CA Civ Proc Code Section 1103

(a)

A writ of prohibition may be issued by any court 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 prohibition directed to the superior court, the superior court is an inferior tribunal for purposes of this chapter.
