Arizona Revised Statutes Title 40. Public Utilities and Carriers § 40-246. Complaint alleging violation by public service corporation of law or rule or order of commission; exception; joinder of complaints; notice of hearing

A. Complaint may be made by the commission of its own motion, or by any person or association of persons by petition or complaint in writing, setting forth any act or thing done or omitted to be done by any public service corporation in violation, or claimed to be in violation, of any provision of law or any order or rule of the commission, but no complaint shall be entertained by the commission, except upon its own motion, as to the reasonableness of any rates or charges of any gas, electrical, water or telephone corporation, unless it is signed by the mayor or a majority of the legislative body of the city or town within which the alleged violation occurred, or by not less than twenty-five consumers or purchasers, or prospective consumers or purchasers, of the service.

B. All matters upon which complaint may be founded may be joined in one hearing, and a complaint is not defective for misjoinder or nonjoinder of parties or causes, either before the commission, or on review by the courts. The commission need not dismiss a complaint because of the absence of direct damage to the complainant.

C. Upon filing the complaint, the commission shall set the time when and a place where a hearing will be had upon it and shall serve notice thereof, with a copy of the complaint, upon the party complained of not less than ten days before the time set for the hearing, unless the commission finds that public necessity requires that the hearing be held at an earlier date. Service may be made as a summons in a civil action is required to be served, or may be made in any manner giving actual notice, and no irregularity in the service is an excuse or defense.
