Intervention

PURPOSE: This rule prescribes the procedures by which an individual or entity may intervene in a case and allows for the filing of briefs by amicus curiae. (1) A motion to intervene or add new member(s) shall be filed within thirty (30) days after the commission issues its order giving notice of the case, unless otherwise ordered by the commission. (2) A motion to intervene or add new member(s) shall include— (A) The legal name of each association, person, or entity seeking intervention or to be added; (B) The street and mailing address of the principal office or place of business of each association, person, or entity seeking intervention or to be added, or of their attorney; (C) The email address, fax number, and telephone number, if any, of each association, person, or entity seeking intervention or to be added, or their attorney; (D) If any applicant is an association, other than an incorporated association or other entity created by statute, a list of all of its members; (E) A statement of the proposed intervenor’s or new member’s interest in the case including the reasons for seeking intervention or to be added; and (F) A statement as to whether the proposed intervenor or new member supports or opposes the relief sought, or a statement that the proposed intervenor or new member is unsure of the position it will take with an explanation of why a position cannot be asserted based upon the initial filing(s) and when such position could be asserted or that the intervenor or new member intends to only provide or receive information and will not take a position on the issues. (3) The commission may grant a motion to intervene or add new member(s) if— (A) The proposed intervenor or new member(s) has an interest which is different from that of the general public and which may be adversely affected by a final order arising from the case; or (B) Granting the proposed intervention would serve the public interest. (4) If the commission grants intervention to an association, other than an incorporated association or other entity created by statute, the commission is not granting intervention to the “association,” but is granting intervention to the individual members of the association. (5) For purposes of 20 CSR 4240-2.080(16), service upon counsel for an association satisfies the requirement for service upon the individual members of the association. (6) If any member(s) of an association, other than an incorporated association or other entity created by statute, that is a party to any case before the commission withdraws from the association during the pendency of a case, the association must file a notice of the member’s(s’) withdrawal in the official case file within five (5) days of the member’s(s’) withdrawal. (7) If an association, other than an incorporated association or other entity created by statute, that is a party to any case before the commission wants to add an additional member(s) during the pendency of that case, the association must file a motion to add new member(s). (8) If the commission finds that the name of any association, other than an incorporated association or other entity created by statute, seeking intervention in a case before the commission could lead to confusion or misidentification of that association or its members, the commission may order that the association be identified by an alternate name in that case. (9) The commission may limit an intervention to particular issues or interests in a case. (10) Motions to intervene or add new member(s) filed after the intervention date may be granted upon a showing of good cause. Any motion so filed must include a definitive statement whether or not the entity seeking intervention or to be added as a new member accepts the record established in that case, including the requirements of any orders of the commission, as of the date the motion is filed. (11) Any person not a party to a case may petition the commission for leave to file a brief as an amicus curiae. The petition for leave must state the petitioner’s interest in the matter and explain why an amicus brief is desirable and how the matters asserted are relevant to the determination of the case. The brief may be submitted simultaneously with the petition. Unless otherwise ordered by the commission, the brief must be filed AND INSURANCE no later than the initial briefs of the parties and comply with all applicable briefing requirements. If leave to file a brief as an amicus curiae is granted, the brief shall be deemed filed on the date submitted. An amicus curiae may not file a reply brief.
