The clerk of the Supreme Court shall keep a calendar under the direction of the Chief Justice in which the dates for oral argument shall be entered.
When an appeal or an original proceeding is set for oral argument the clerk shall give written notice by first class mail to all attorneys of record in the case stating the date and place that argument will be heard. If any party is not represented by an attorney, such notice shall be given to such party by mailing to his last known post office address. The court may in its discretion consider the appeal on the briefs and record without oral argument.
