The court may refuse to accept a plea of guilty or nolo contendere.
If a defendant refuses to plead, or if the court refuses to accept a plea of guilty or nolo contendere, the court shall enter a plea of not guilty.
If the defendant prevails on appeal, the defendant shall be allowed to withdraw the plea.
If the court refuses to accept the plea or the defendant, after waiving indictment in open court, declines to plead guilty or if a plea of guilty is set aside, the waiver shall be considered withdrawn and the case shall proceed in accordance with these Rules as if no waiver had been made.
The court receiving a case transferred for plea and sentence shall issue an order that either requires the case to remain in the sentencing court or requires the case to be returned to the originating court.
