Code of Civil Procedure section 77
(a)
In every county there is an appellate division of the superior court consisting of three judges or, when the Chief Justice finds it necessary, four judges.(b)
In each appellate division, no more than three judges shall participate in a hearing or decision. The presiding judge of the division shall designate the three judges who shall participate.(c)
In addition to their other duties, the judges designated as members of the appellate division of the superior court shall serve for the period specified in the order of designation. Whenever a judge is designated to serve in the appellate division of the superior court of a county other than the county in which that judge was elected or appointed as a superior court judge, or if the judge is retired, in a county other than the county in which the judge resides, the judge shall receive expenses for travel, board, and lodging. If the judge is out of the judge’s county overnight or longer, by reason of the designation, that judge shall be paid a per diem allowance in lieu of expenses for board and lodging in the same amounts as are payable for those purposes to justices of the Supreme Court under the rules of the Department of General Services. In addition, a retired judge shall receive for the time so served, amounts equal to that which the judge would have received if the judge had been assigned to the superior court of the county.(d)
The concurrence of two judges of the appellate division of the superior court shall be necessary to render the decision in every case in, and to transact any other business except business that may be done at chambers by the presiding judge of, the division. A judgment of the appellate division in an appeal shall contain a brief statement of the reasons for the judgment. A judgment stating only “affirmed” or “reversed” is insufficient. The presiding judge shall convene the appellate division when necessary. The presiding judge shall also supervise its business and transact any business that may be done at chambers.(e)
The appellate division of the superior court has jurisdiction on appeal in all cases in which an appeal may be taken to the superior court or the appellate division of the superior court as provided by law, except where the appeal is a retrial in the superior court.(f)
The powers of each appellate division shall be the same as are now or may hereafter be provided by law or rule of the Judicial Council relating to appeals to the appellate division of the superior courts.(g)
The Judicial Council shall promulgate rules, not inconsistent with law, to promote the independence of, and govern the practice and procedure and the disposition of the business of, the appellate division.(h)
Notwithstanding subdivisions (b) and (d), appeals from convictions of traffic infractions may be heard and decided by one judge of the appellate division of the superior court.
