California Code, Code of Civil Procedure - CCP § 902.1

In any case in which a notice was required pursuant to subdivision (e) of Section 664.5, the Attorney General shall have the right to intervene and participate in any appeal taken therefrom. These rights shall apply regardless of whether the Attorney General participated in the case in the trial court. However, the Attorney General has no direct right to appeal. If the Attorney General elects not to intervene and participate in the appeal, he or she shall file a statement with the Legislature and the Judicial Council stating the reason or reasons for the decision not to intervene and participate in the appeal. This statement may be in the form of an annual report to the Legislature and Judicial Council and that report shall be a matter of public record.
