In Jacobs v. State Bar (1977) 20 Cal.3d 191, the Supreme Court held that because of its "sole original jurisdiction to disbar or suspend an attorney," the superior court does not have the authority to review the validity of a State Bar subpoena at the request of an attorney who is subject to a State Bar preliminary investigation. (Jacobs, supra, 20 Cal.3d at pp. 196-197.) The court noted that the attorney could move to quash a subpoena with the State Bar investigating committee, and "once remedies available from the local committee are exhausted, any decision by the State Bar related to disciplinary matters is reviewable by us under California Rules of Court, rule 952(c) now rule 9.13(d)." (Id. at p. 198.)
