Article 15 of the Arizona Constitution establishes the Arizona Corporation Commission. Only 7 states have constitutionally formed Commissions. Arizona is one of only 13 states with elected Commissioners. In the 37 other states, Commissioners are appointed by either the governor or the legislature.
In most states, the Commission is known as the Public Service Commission or the Public Utility Commission. Our Commission, however, has responsibilities that go beyond traditional public utilities regulation. These additional roles include facilitating the incorporation of businesses and organizations, securities regulation and railroad/pipeline safety.
By virtue of the Arizona Constitution, the Commissioners function in an Executive capacity, they adopt rules and regulations thereby functioning in a Legislative capacity, and they also act in a Judicial capacity sitting as a tribunal and making decisions in contested matters.
