Which of the following is NOT a power of the Arizona Corporation Commission?

The Arizona Corporation Commission is primarily responsible for overseeing various functions related to public services and regulation of securities. Its powers include setting utility rates to ensure fair pricing for consumers, regulating the securities market to protect investors, and ensuring compliance among public corporations with state laws.

However, the Commission does not have oversight of the court system. The court system operates independently and is governed by the judicial branch of state government. Therefore, it is accurate to identify the oversight of the court system as a responsibility that does not fall under the powers of the Arizona Corporation Commission. This distinction highlights the specific roles of different branches of government and the separation of powers that is fundamental in the governance structure of Arizona.
