Rule RAP 9 - Intervention on Appeal(A) Upon motion or recommendation by the court anyone may be permitted to intervene on appeal for the reasons in CR 24.01(1) and CR 24.02, except that intervention on appeal is discretionary with the court.(B) A motion to intervene shall state the proposed intervenor's interest in the appeal; state whether the proposed intervenor seeks to file a separate brief, to join in the brief of a party to the appeal, or to file a joint brief with another proposed intervenor; and set forth the reasons intervention would assist the court. When the constitutionality of an act of the General Assembly was raised in the trial court and is drawn into question by the proposed intervenor, the proposed intervenor shall serve a copy of the motion upon the Attorney General. The motion shall otherwise conform to RAP 7 with service on all parties to the appeal.(C) Any party objecting to the proposed intervention may file a response within 10 days. The response shall otherwise conform to RAP 7 with service on all parties and the proposed intervenor. The court shall determine, in its discretion, whether intervention shall be granted and, if so, whether the proposed intervenor shall be aligned as appellant or appellee and whether the proposed intervenor shall be permitted to file a separate brief.Adopted by order 2022-49, eff. 1/1/2023.
