1. All motions to the court shall be reduced to writing, and shall contain a brief statement of the facts and objects of the motion.

2. One hour on each side shall be allowed to the argument of a motion, and no more, without special leave of the court, granted before the argument begins.

3. No motion to dismiss, except on special assignment by the court, shall be heard, unless previous notice has been given to the adverse party, or the counsel or attorney of such party.

4. All motions to dismiss writs of error and appeals, except motions to docket and dismiss under Rule 9, must be submitted in the first instance on printed briefs or arguments. If the court desires further argument on that subject, it will be ordered in connection with the hearing on the merits. The party moving to dismiss shall serve notice of the motion, with a copy of his brief of argument, on the counsel for plaintiff in error or appellant of record in this court, at least three weeks before the time fixed for submitting the motion, in all cases except where the counsel to be notified resides west of the Rocky Mountains, in which case the notice shall be at least thirty days. Affidavits of the deposit in the mail of the notice and brief to the proper address of the counsel to be served, duly postpaid, at such time as to reach him by due course of mail, the three weeks or thirty days before the time fixed by the notice, will be regarded as prima facie evidence of service on counsel who reside without the District of Columbia. On proof of such service, the motion will be considered, unless, for satisfactory reasons, further time be given by the court to either party.

5. There may be united, with a motion to dismiss a writ of error or an appeal, a motion to affirm on the ground that, although the record may show that this court has jurisdiction, it is manifest the writ or appeal was taken for delay only, or that the question on which the jurisdiction depends is so frivolous as not to need further argument.

6. The court will not hear arguments on Saturday (unless for special cause it shall order to the contrary), but will devote that day to the other business of the court. The motion-day shall be Monday of each week; and motions not required by the rules of the court to be put on the docket shall be entitled to preference immediately after the reading of opinions, if such motions shall be made before the court shall have entered upon the hearing of a case upon the docket.
