California Code, Elections Code - ELEC § 16640

If the number of votes that are sought to be recounted or the number of contests are such that the judge in a county in which there is but one superior court judge is of the opinion that it will require additional judges to enable the contest or contests to be determined in time to print the ballots for the election, he or she may obtain the service of any other superior judge, and the proceedings shall be the same as provided for a county in which there is more than one superior court judge.
