PHOENIX — A judge has once again slapped down efforts by Attorney General Mark Brnovich to challenge what he contends is an illegal deal by the Arizona Board of Regents to build a hotel and conference center.

In a ruling late Wednesday, Tax Court Judge Christopher Whitten did not address Brnovich’s contention that the deal violates the Gift Clause of the Arizona Constitution. That claim is based on the idea that the Arizona Board of Regents is effectively providing a subsidy to the private developer by paying for a conference center that the university would be able to use just seven days a year.

There’s also a separate legal question of having what amounts to a tax exemption for the hotel because it is being built on tax-exempt university property.

What Whitten does say is that the legal claim came too late, meaning he has no legal right to decide if Brnovich is right or wrong.

In a prepared statement, Larry Penley, president of the Board of Regents, praised the ruling — and the implications for similar developments.

“Leveraging our real estate provides an entrepreneurial opportunity to increase revenues to benefit students, the community and the state of Arizona,’’ he said.

But this isn’t the end of it.

Brnovich press aide Ryan Anderson vowed an appeal. He said the judge got it wrong in deciding the claim came too late.

And even if Brnovich ultimately loses, Wednesday’s ruling does not provide a clear legal path for the regents to engage in similar deals. It still leaves the door open for Brnovich to sue to block similar deals in the future at any of the state’s three universities — if he files suit on time.

Central to Wednesday’s ruling is the fact that lawsuits of this kind must be filed within a year of someone learning about a questionable legal practice. And Brnovich did sue on Jan. 10.

But the paperwork filed at that time dealt only with questions about the authority of the Board of Regents to enter into a deal to create a 330-room Omni hotel and a 30,000-square-foot conference center on land that is owned by Arizona State University.

It was only on April 3 that Brnovich amended the complaint to add the Gift Clause allegations.

Whitten said that means if the attorney general knew or should have known about the issue before April 3, 2018 — that one-year statute of limitations — he should have acted by then.

But Whitten said the evidence shows that attorneys within Brnovich’s office circulated and discussed a report by the Arizona Tax Research Association as early as January 2018 which criticized the regents for leasing their property to private entities.

That report, the judge said, opined that such transactions were “dubious’’ under the Gift Clause.

Whitten also noted that Rep. Athena Salman, D-Tempe, wrote an op-ed in the Arizona Republic that same month critical of the deal, though it focused more on the $21 million in tax breaks from the city of Tempe. That article, the judge said, also circulated within the Attorney General’s Office, with one of the lawyers there commenting that an element of the deal “sounds pretty suspicious.’’

He acknowledged there were certain elements about the Omni deal which the Attorney General’s Office did not actually know about until after April 3, 2018, one year before the amended complaint was filed. That includes things like the number of days Arizona State University would have free use of the conference center.

But the judge said that didn’t matter.

“The statute of limitations ... does not accrue when all the details of a claim became known to the plaintiff,’’ he wrote. “It accrues when enough details of the deal were known, or should have been, that the plaintiff could identify that a wrong had occurred and caused injury.’’

And in this case, Whitten said, the key elements were known more than a year before Brnovich filed his amended complaint in April of this year. That specifically includes the fact that ASU would pay $19.5 million to build the conference center -- a facility it would have use of without cost only seven days a year -- and that the hotel operators would not pay property taxes because the facility was built on property owned by the regents.

ASU officials, in a prepared statement, said the school is “committed to transparency and welcomes inquiry from anyone at any time, including the attorney general, about our projects.’’ But it also took a slap of sort at Brnovich.

“At no time did he bother to inquire,’’ the statement reads.

Brnovich, for his part, is undeterred by the ruling.

“Any time you take on the establishment, it’s never an easy fight,’’ he said in his own prepared statement. “We will continue to fight for Arizona taxpayers, for greater transparency and fiscal accountability from our public universities.’’

That issue of transparency came up earlier this year in a review by the Auditor General’s office of the practices of the regents in leasing out their property for commercial use. That report concluded there was a lack of proper oversight and limited transparency, creating a “risk of inappropriate use of public resources.’’

The appeal Brnovich promises will address more than just Whitten’s ruling on the timeliness of the Gift Clause claim.

Earlier this year Whitten threw out other parts of the challenge by Brnovich, including whether state universities can lease out the land they own for private, for-profit operations.

The judge said Arizona law gives the Board or Regents the authority to buy, hold and sell real estate. That power, he wrote, specifically includes the power to enter into leases of the land it owns.

And in this case, Whitten said, the deal to create the hotel and conference center on land that is owned by Arizona State University clearly is a lease.

The judge also would not let Brnovich claim that, by seeking to void the deal, he is enforcing laws to ensure that all property is being properly taxed.

“As a matter of law, the property on which the Attorney General seeks to collect tax is constitutionally exempt from taxation," Whitten wrote, because it belongs to the universities and the regents. “There is no tax owing, and nothing for the Attorney General to enforce."
