Notwithstanding any other provision of law, if the court has ordered an issue or issues bifurcated for separate trial or hearing in advance of the disposition of the entire case, a court of appeal may order an issue or issues transferred to it for hearing and decision when the court that heard the issue or issues certifies that the appeal is appropriate. Certification by the court shall be in accordance with rules promulgated by the Judicial Council.
