(a) The time for oral argument in this Court and in each district of the court of appeals shall be as ordered by the court in which the appeal is pending. Time may be extended by the presiding judge to the extent of time taken by questions from the bench and answers thereto. The appellant may divide the allotted time between the original and reply argument, but no more than one-fourth of the time shall be consumed by reply argument. Cross-appeals shall be treated as one cause, and in such case the plaintiff in the trial court shall be entitled to the time allotted to the appellant and the defendant in the trial court to the time allotted to the respondent, unless the parties otherwise agree or the court otherwise orders.

(b) Any party, intervenor, or amicus who does not file a brief on appeal or whose brief has been stricken will not be permitted to present oral argument unless permitted by the court for good cause shown.
