Arizona Revised Statutes Title 30. Power § 30-809. Action to set aside or modify certain governing body of public power entity orders or decisions; limitation; court of appeals

A. The attorney general on behalf of this state or any person that is dissatisfied with any order or decision of the governing body of the public power entity made in the course of a ratemaking or rate design process may file, within thirty days after a rehearing is denied or deemed denied, a notice of appeal in the court of appeals to vacate, set aside, affirm in whole or in part, reverse in part or remand with instructions to the governing body of the public power entity the order or decision if the court of appeals determines that it is unlawful, that it is not supported by substantial evidence or that the governing body abused its discretion.

B. If the governing body of the public power entity rescinds the order complained of, the action shall be dismissed, and if the governing body of the public power entity alters, modifies or amends the order, the altered, modified or amended order shall replace the original order complained of, and judgment shall be given on the order as made by the governing body of the public power entity in the first instance.

C. The appellate procedure shall be pursuant to rules adopted by the supreme court. The rules shall conform, as nearly as possible, to the manner in which other appeals are undertaken including indicating the content of the record on review, the briefs to be filed and the time and manner for filing the briefs, record and other documents.

D. Any party to the action, or the attorney general on behalf of this state, may appeal to the supreme court as provided by law.

E. In all appeals taken pursuant to this section, the party adverse to the governing body of the public power entity or the party seeking to vacate or set aside an order of the governing body of the public power entity must show that the order or decision is unlawful, that it is not supported by substantial evidence or that the governing body abused its discretion.

F. Except as provided by this section, a court of this state does not have jurisdiction to enjoin, restrain, suspend, delay or review any order or decision of the governing body of the public power entity involving any public power entity and made in the course of a ratemaking or rate design process or to enjoin, restrain or interfere with the governing body of the public power entity in the performance of its official duties and the rules, orders or decrees fixed by the governing body of the public power entity remain in force pending the decision of the courts, but a writ of mandamus shall lie from the supreme court to the governing body of the public power entity in cases authorized by law.
