In the event of the disqualification, illness, or absence of the judge of the juvenile court, the judge of the juvenile court may appoint any attorney at law resident in the judicial circuit in which the court lies, any judge or senior judge of the superior courts, or any duly appointed juvenile court judge to serve as judge pro tempore of the juvenile court. In the event the judge of the juvenile court is absent or unable to make such appointment, the judge of the superior court of that county may so appoint. The person so appointed shall have the authority to preside in the stead of the disqualified, ill, or absent judge and shall be paid from the county treasury such emolument as the appointing judge shall prescribe; provided, however, that the emolument shall not exceed the compensation received by the regular juvenile court judge for such services.
