(a) Availability. The Commission, on its own motion or the motion of a party or any other aggrieved person entitled to Commission review, may order oral argument with respect to any matter. Motions for oral argument with respect to whether to affirm all or part of an initial decision by a hearing officer shall be granted unless exceptional circumstances make oral argument impractical or inadvisable. The Commission will consider appeals, motions and other matters properly before it on the basis of the papers filed by the parties without oral argument unless the Commission determines that the presentation of facts and legal arguments in the briefs and record and the decisional process would be significantly aided by oral argument.

(b) Procedure. Requests for oral argument shall be made by separate motion accompanying the initial brief on the merits. The Commission shall issue an order as to whether oral argument is to be heard, and if so, the time and place therefor. If oral argument is granted, the time fixed for oral argument shall be changed only by written order of the Commission, for good cause shown. The order shall state at whose request the change is made and the reasons for any such changes. No visual aids may be used at oral argument unless copies have been provided to the Commission and all parties at least five business days before the argument is to be held.

(c) Time allowed. Unless the Commission orders otherwise, not more than one half-hour per side will be allowed for oral argument. The Commission may, in its discretion, determine that several persons have a common interest, and that the interests represented will be considered a single side for purposes of allotting time for oral argument. Time will be divided equally among persons on a single side, provided, however, that by mutual agreement they may reallocate their time among themselves. A request for additional time must be made by motion filed reasonably in advance of the date fixed for argument.

(d) Participation of Commissioners. A member of the Commission who was not present at the oral argument may participate in the decision of the proceeding, provided that the member has reviewed the transcript of such argument prior to such participation. The decision shall state whether the required review was made.
