Cal. Penal Code - PEN § 1471. Section 1471.
A court of appeal may order any case on appeal to a superior court in its district transferred to it for hearing and decision as provided by rules of the Judicial Council when the superior court certifies, or the court of appeal determines, that such transfer appears necessary to secure uniformity of decision or to settle important questions of law.
A court to which any such case is transferred shall have similar power to review any matter and make orders and judgments as the appellate division of the superior court by statute would have in such case, except as otherwise expressly provided.
