​AG Mayes filed an Application for Rehearing challenging a recent Arizona Corporation Commission decision that approved a new rate-setting mechanism for UNS Gas, Inc. that could lock in automatic annual rate increases for the company’s ratepayers with little meaningful oversight.

"Arizonans deserve utility rates that are fair and transparent, not a rubber stamp process designed to increase rates automatically. This mechanism strips ratepayers of the due process protections they’re entitled to under the Arizona Constitution." – AG Mayes
