Ariz. R. Civ. App. P. 25
An appellate court may impose sanctions on an attorney or a party if it determines that an appeal or a motion is frivolous, or was filed solely for the purpose of delay. An appellate court also may impose sanctions on an attorney or a party for a violation of these Rules. An appellate court may impose sanctions that are appropriate in the circumstances of the case, and to discourage similar conduct in the future. Sanctions may include contempt, dismissal, or withholding or imposing costs or attorneys' fees.
