Rule 8.30 - DISQUALIFICATION OF JUDGE(1) If a party or counsel for a party discovers that a sitting Court of Appeals or Supreme Court judge participated in the case in the proceedings being appealed or reviewed, the party or counsel shall notify the Administrator by letter of the judge's participation as soon as possible after discovering the judge's participation.(2) The duty of a party or counsel to notify the Administrator of a sitting appellate judge's previous participation in the proceeding includes, in post-conviction relief and habeas corpus cases, the underlying criminal proceeding.(3)(a) In addition to the notice required by subsection (1) of this rule, a party or attorney for a party in a case before the Supreme Court or Court of Appeals may move to disqualify a judge of the Supreme Court or Court of Appeals for one or more of the grounds specified in ORS 14.210, or upon the ground that the judge's participation in the case would violate the Oregon Code of Judicial Conduct. The motion shall be filed as soon as practicable after the party or attorney learns of the ground for disqualification. (b)(i) The Administrator shall forward a copy of the motion to the judge against whom the motion is directed without waiting for an answer to the motion. The judge may grant the motion with or without an answer having been filed. If the judge does not believe that the motion is well taken, the judge shall refer the motion to the presiding judge for decision. The judge's referral may be accompanied by any written response the judge may wish to make. If the judge accompanies the referral with written response, the judge shall provide the parties with a copy of the written comments. The presiding judge may rule on the motion or may refer the motion to the full court for a decision. (ii) In the Court of Appeals, "presiding judge" means the Chief Judge, unless the motion to disqualify is directed at the Chief Judge, in which case "presiding judge" means the next senior judge available to rule on the motion. In the Supreme Court, "presiding judge" means the Chief Justice, unless the motion to disqualify is directed at the Chief Justice, in which case "presiding judge" means the next senior judge available to rule on the motion.
