Rule 25. Brief of an amicus curiae or guardian ad litem.
A brief of an amicus curiae or of a guardian ad litem representing a minor who is not a party to the appeal may be filed only by leave of court granted on motion or at the request of the court. The motion for leave may be accompanied by a proposed amicus brief, provided it complies with applicable rules and the number of copies specified by Rule 26(b) are submitted to the court. A motion for leave shall identify the interest of the movant and shall state the reasons why a brief of an amicus curiae or the guardian ad litem is desirable. Except for a motion for leave to participate in support of, or in opposition to, a petition for writ of certiorari filed pursuant to Rule 50(f),the motion for leave shall be filed at least 21 days prior to the date on which the brief of the party whose position as to affirmance or reversal the amicus curiae or guardian ad litem will support is due, unless the court for cause shown otherwise orders. Parties to the proceeding may indicate their support for, or opposition to, the motion. Any response of a party to a motion for leave shall be filed within 7 days of service of the motion. If leave is granted, an amicus curiae or guardian ad litem shall file its brief within 7 days of the time allowed the party whose position the amicus curiae or guardian ad litem will support, unless the order granting leave otherwise indicates. The time for responsive briefs under Rule 26(a) shall run from the timely service of the amicus or guardian ad litem brief or from the timely service of the brief of the party whose position the amicus curiae or guardian ad litem supports, whichever is later. A motion of an amicus curiae or guardian ad litem to participate in the oral argument will be granted when circumstances warrant in the court's discretion.
