It is the duty of each party at all times during the course of an appeal to inform the court of any circumstances which have transpired subsequent to the filing of the appeal which render moot one or more of the issues raised. If the parties to an appeal or other proceeding sign and file with the clerk an agreement that the proceeding be dismissed, specifying the terms as to payment of costs and pay whatever fees are due, the clerk shall enter an order of dismissal. Absent such agreement, an appeal may be dismissed on motion of the appellant upon such terms as to payment of costs and fees as the court may order. If appellant has the right to effective assistance of counsel, the appeal may be dismissed only if appellant's motion is accompanied by appellant's personal affidavit demonstrating that appellant's decision to dismiss the appeal is voluntary and made with knowledge of the right to an appeal and an understanding of the consequences of voluntary dismissal. 1999 Advisory Committee Note .
