If the court has determined that the relator is entitled to a peremptory writ of mandamus, the court shall direct the Administrator to issue the writ. The peremptory writ may be combined with the appellate judgment and issued together as a single document. If the peremptory writ and the appellate judgment are combined, the relator need not file proof of service of the writ with the court, and the judge or court to which the writ is issued in a mandamus proceeding that challenges the action of a judge in a particular case in the circuit court, the Tax Court, or the Court of Appeals or the defendant in any other mandamus proceeding need not file a return showing compliance with the writ.
