An application to the court for an order shall be by motion. A motion other than one made during a trial or hearing shall be in writing unless the court permits it to be made orally. It shall state the grounds upon which it is made and shall set forth the relief or order sought. It may be supported by affidavit. The court will not consider pro se applications by defendants who are represented by counsel unless the defendant has been granted permission to participate with counsel in the defense.
