Benedon has served in the attorney general’s office as the director of the Division of Open Government, where she oversaw the resolution of more than 2,000 oversaw the resolution of more than 2,000 formal Open Meeting Law complaints.

“I am confident that Carrie’s longstanding commitment to good governance, vast experience in advising state agencies, and demonstrated commitment to efficiency, social justice, and integrity will be integral in the Commission’s work to ensure fairness and transparency,” Campbell said.

Benedon joined the attorney general’s office in 2012 as an assistant attorney general with the Constitutional and Administrative Law Division. She also represented the Department of Public Health in cases challenging its medical marijuana registration and licensing authority prior to the creation of the CCC.

With Benedon’s appointment, the CCC will fill all of its five seats. The CCC’s chair, Shannon O’Brien, was reinstated by a judge in September after a monthslong court battle between Goldberg and O’Brien, who alleged wrongful termination.

The CCC has come under scrutiny over allegations of dysfunction, high staff turnover, and firings. State Auditor Diana DiZoglio found widespread mismanagement and violations of state regulations in a two-year audit published in August. In response at the time, the commission said it was making progress on addressing weaknesses identified by the audit.

The seat Benedon will take, under the law, should be filled by someone with a background in legal, policy, or social justice issues related to a regulated industry, according to the news release.

“[Benedon’s] understanding of transparency laws, along with her commitment to social justice and equity, will strongly benefit the Commission as they continue to serve the public,” Goldberg said.
