New allegations of bias were leveled at three members of the Arizona Corporation Commission in legal papers filed Thursday on behalf of two former commissioners.
The complaints were filed by former Tempe Mayor Hugh Hallman, an attorney representing former commissioners Bill Mundell and Renz Jennings and Sunrun Inc., a residential solar-panel leasing company.
They seek to disqualify the three elected regulators from considering a proposed rate increase on new solar customers because the regulators aren’t seen as impartial.
The filings escalate a credibility debate already engulfing the state’s utility regulators.
