Parties shall be entitled to a hearing before a panel of not less than three intermediate appellate judges. In case of vacancy, or if the number of available intermediate appellate judges is insufficient to make up a panel because of disqualification, the chief justice of the supreme court may designate circuit judges, retired intermediate appellate judges, or retired supreme court justices to temporarily fill the vacancy or the need to make up a panel. A judge serving temporarily shall not be actively engaged in the practice of law. Substitute judges shall be compensated per diem at a rate of pay equivalent to that of associate intermediate appellate judges.
