(a) When ordered. Upon motion of any party or upon its own motion, the Commission may order oral argument. Parties requesting oral argument must demonstrate why oral argument would facilitate resolution of the issues before the Commission. Normally, motions for oral argument shall not be considered until after all briefs have been filed.

(b) Notice of argument. The Executive Secretary shall advise all parties whether oral argument is to be heard. Within a reasonable time before the oral argument is scheduled, the Executive Secretary shall inform the parties of the time and place therefor, the issues to be heard, and the time allotted to the parties.

(c) Postponement. (1) Except under extraordinary circumstances, a request for postponement must be filed at least 10 days before oral argument is scheduled.

(2) The Executive Secretary shall notify the parties of a postponement in a manner best calculated to avoid unnecessary travel or inconvenience to the parties. The Executive Secretary shall inform all parties of the new time and place for the oral argument.

(d) Order and content of argument. (1) Counsel shall be afforded such time for oral argument as the Commission may provide by order. Requests for enlargement of time may be made by motion filed reasonably in advance of the date fixed for the argument.

(2) The petitioning party shall argue first. If the case is before the Commission on cross-petitions, the Commission will inform the parties in advance of the order of appearance.

(3) Counsel may reserve a portion of the time allowed for rebuttal but in opening argument shall present the case fairly and completely and shall not reserve points of substance for presentation during rebuttal.

(4) Oral argument should undertake to emphasize and clarify the written arguments appearing in the briefs. The Commission will look with disfavor on any oral argument that is read from a previously filed document.

(5) At any time, the Commission may terminate a party's argument or interrupt the party's presentation for questioning by the Commissioners.

(e) Failure to appear. Should either party fail to appear for oral argument, the party present may be allowed to proceed with its argument.

(f) Consolidated cases. Where two or more consolidated cases are scheduled for oral argument, the consolidated cases shall be considered as one case for the purpose of allotting time to the parties unless the Commission otherwise directs.

(g) Multiple counsel. Where more than one counsel argues for a party to the case or for multiple parties on the same side in the case, it is counsels' responsibility to agree upon a fair division of the total time allotted. In the event of a failure to agree, the Commission will allocate the time. The Commission may, in its discretion, limit the number of counsel heard for each party or side in the argument. No later than 5 days prior to the date of scheduled argument, the Commission must be notified of the names of the counsel who will argue.

(h) Exhibits/visual aids. (1) The parties may use exhibits introduced into evidence at the hearing. If a party wishes to use a visual aid not part of the record, written notice of the proposed use shall be given to opposing counsel 15 days prior to the argument. Objections, if any, shall be in writing, served on all adverse parties, and filed not fewer than 7 days before the argument.

(2) No visual aid shall introduce or rely upon facts or evidence not already part of the record.

(3) If visual aids or exhibits other than documents are to be used at the argument, counsel shall arrange with the Executive Secretary to have them placed in the hearing room on the date of the argument before the Commission convenes.

(4) Parties using visual aids not introduced into evidence shall have them removed from the hearing room unless the Commission directs otherwise. If such visual aids are not reclaimed by the party within a reasonable time after notice is given by the Executive Secretary, such visual aids shall be disposed of at the discretion of the Executive Secretary.

(i) Recording oral argument. (1) Unless the Commission directs otherwise, oral arguments shall be electronically recorded and made part of the record. Any other sound recording in the hearing room is prohibited. Oral arguments shall also be transcribed verbatim. A copy of the transcript of the oral argument taken by a qualified court reporter, shall be filed with the Commission. The Commission shall bear all expenses for court reporters' fees and for copies of the hearing transcript received by it.

(2) Persons desiring to listen to the recordings shall make appropriate arrangements with the Executive Secretary. Any party desiring a written copy of the transcript is responsible for securing and paying for its copy.

(3) Error in the transcript of the oral argument may be corrected by the Commission on its own motion, on joint motion by the parties, or on motion by any party. The motion shall state the error in the transcript and the correction to be made. The official transcript shall reflect the corrections.

(j) Failure to file brief. A party that fails to file a brief shall not be heard at the time of oral argument except by permission of the Commission.

(k) Participation in oral argument by amicus curiae. (1) An amicus curiae will not be permitted to participate in the oral argument without leave of the Commission upon proper motion. Participation generally will be limited to a portion of the time allotted to the party in whose interest the amicus curiae seeks to participate. In extraordinary circumstances, the amicus curiae may be allotted its own time for oral argument.

(2) A motion by amicus curiae seeking leave to participate in oral argument shall be filed no later than 14 days prior to the date oral argument is scheduled.

(3) The motion of an amicus curiae for leave to participate at oral argument shall identify the interest of the applicant and shall state the reason(s) why its participation at oral argument is desirable.

(4) Motions in opposition to the motion of an amicus curiae for leave to participate in the oral argument must be filed within 10 days of the date of the motion.
