(1) Any party may seek relief in a contested case by means of an appropriate motion. Motions shall clearly state the relief sought by a party, the grounds and authority supporting the entry of an order granting the motion, any prejudice which would result should the motion be denied, and the precise relief desired. All motions which assert factual matters not of record as the grounds for relief must be accompanied by affidavits or verified exhibits which show the facts upon which the proposed relief is grounded. Each motion must be supported by a brief or memorandum of law showing the moving party's entitlement to relief as a matter of law.(2) The hearing officer may deny any motion which is not supported by an affidavit, where required, and which is not supported by a brief or memorandum of law.(3) Upon filing a motion, the moving party shall file its supporting brief and any other supporting materials. Within ten days after service of that brief, the opposing party shall file an answer brief and any other supporting materials. Within ten days after the service of the answer brief, the moving party may file a reply brief or other appropriate response.(4) The failure of a moving party to file a brief in support of the motion may be treated as an admission that the motion is without merit. The failure to file an answer brief may be treated as an admission the motion is well taken and should be granted. The filing of a reply brief by the movant is optional and failure to file one will not subject the motion to summary ruling.(5) The hearing officer may order live or telephonic oral argument upon a motion on its own motion or that of a party. Oral argument on any motion, including a motion for summary judgment, is waived unless requested by the moving party in the moving party's brief in support of the motion or by the party responding to the motion in the answer brief.(6) At the discretion of the hearing officer, oral motions may be heard during the course of a hearing or in extraordinary situations which do not result in prejudice to a party.NEW, 2008 MAR p. 2636, Eff. 12/25/08.49-2-204, 49-3-106, MCA; IMP, 49-2-505, 49-3-315, MCA;
