Complaints against attorneys are investigated and prosecuted by the State Bar's Office of the Chief Trial Counsel. Under the State Bar Act, upon receiving a complaint, the Bar may choose whether to open an investigation. If the Bar does find sufficient evidence of misconduct, decides that it has standing, and decides to take action to impose discipline, it has the power to proceed against accused attorneys either in the Supreme Court of California or in the State Bar Court. The State Bar holds that it may decline to review complaints that are not made by a judge who heard a matter related to the complaint.
