Appeals Determined by Three Justices. Appeals to the Supreme Court shall be heard and determined by a panel consisting of the Chief Justice and two Associate Justices. If the Chief Justice is disqualified, he or she shall appoint a temporary Chief Justice to act in his or her stead. The concurrence of two justices shall be necessary to any decision of the Supreme Court on the merits of an appeal. However, the Supreme Court may provide by rule for hearing and disposition of matters involving an appeal, other than the merits of the case, by a single justice. Source: PL 6-25, § 3, ch. 1 (§ 3107).
