(a) Motion. A party may file a motion to recuse a justice or judge before whom the case is pending. The motion must be filed promptly after the party has reason to believe that the justice or judge should not participate in deciding the case.
(b) Decision. Before any further proceeding in the case, the challenged justice or judge must either remove himself or herself from all participation in the case or certify the matter to the entire court, which will decide the motion by a majority of the remaining judges sitting en banc. The challenged justice or judge must not sit with the remainder of the court to consider the motion as to him or her.
(c) Appeal. An order of recusal is not reviewable, but the denial of a recusal motion is reviewable.
