PHOENIX (AZFamily) — A conservative-leaning think tank is suing Arizona Attorney General Kris Mayes over her office’s refusal to fully disclose records related to allegations of rental price-fixing involving major landlords and a property management software company.

The Goldwater Institute filed a public records lawsuit against Mayes, demanding she reveal how many people have filed complaints related to the allegations.

In a news release, the think tank said Mayes has refused to state how many Arizonans claimed the alleged conspiracy actually harmed them.

In February 2024, the AG’s office sued nine landlords, including Avenue5, Greystar, RPM Living, and Weider. State officials also named RealPage, a property management software company, in the lawsuit, alleging it colluded with others to inflate rental prices across metro Phoenix.

The Goldwater Institute said it had requested full complaint records from Mayes’ office but reportedly only received a numerical count of complaints, without the underlying records.

“I firmly believe in vindicating Arizona’s Public Records Law, which exists to ensure that government remains accountable to the people it serves,” said Michael Bloom, an attorney for the American Freedom Network, which is representing the Goldwater Institute. “Transparency is the cornerstone of public trust.”

Goldwater officials said the AG’s office claimed the information was confidential, but they argue it is not protected under public records law.

The think tank also noted that Mayes’ lawsuit mirrors similar cases filed by other Democratic attorneys general, and partnered with a private law firm to pursue the case, similar to approaches taken in those other states.

Last year, the Justice Department filed an antitrust lawsuit against RealPage, accusing it of an illegal scheme that allowed landlords to coordinate and hike up rent prices.
