Legal Opinions of the Attorney General - Opinion Unit

As the chief law officer of the state, the California Attorney General provides legal opinions upon request to designated state and local public officials and government agencies on issues arising in the course of their duties. The formal legal opinions of the Attorney General have been accorded "great respect" and "great weight" by the courts.

The Attorney General's authority to issue opinions is controlled by Government Code section 12519.

Government Code section 12519 states:

 The Attorney General shall give the Attorney General's opinion in writing to any Member of the Legislature, the Governor, Lieutenant Governor, Secretary of State, Controller, Treasurer, State Lands Commission, Superintendent of Public Instruction, Insurance Commissioner, any state agency, and any county counsel, district attorney, or sheriff when requested, upon any question of law relating to their respective offices.

 The Attorney General shall give the Attorney General's opinion in writing to a city prosecuting attorney when requested, upon any question of law relating to criminal matters.

Under this statute, the Attorney General may give opinions only to these specified public officials, and not to private citizens or to public officials who are not listed in the statute.

How to Submit a Quo Warranto Application

Quo warranto is a special form of legal action, most often used to resolve a dispute over whether a specific person has the legal right to hold the public office that he or she currently occupies. The statutes relating to quo warranto are in the California Code of Civil Procedure, starting at section 803. Generally speaking, a quo warranto action may not be filed without the approval of the Attorney General. In order to obtain the Attorney General’s approval, a private person or a local agency must file an application pursuant to the rules and regulations issued by the Attorney General. (Cal. Code Regs., tit. 11, §§ 1-11.) The application and supporting documents must be prepared by a licensed attorney. More information on preparing an application is available on our Quo Warranto page.
