In Ligda v. Superior Court (1970) 5 Cal.App.3d 811, a deputy public defender was ordered by the trial court to assist a defendant acting in propria persona. The appellate court denied the petition of the Public Defender of Solano County for a writ of prohibition to annul the trial court's order. The deputy had already appeared in the cause and the court ordered him to "serve in the more limited . . . function of advising and assisting . . ." the particular defendant in his self-representation. The deputy public defender in Ligda was acting: (1) pursuant to order of the trial court; and (2) on behalf of a specific individual. If the extension of the duties of the public defender in Ligda was a "progressive expansion" (as characterized by the court), the extension proposed here may be described as radical.
