Utah Supreme Court Justice Diana Hagen resigned effective immediately this week, ending a career on the bench that spanned nine years, and ending a scandal that had engulfed the state's highest court for nearly a month. Her departure came as Republican state leaders were preparing an independent investigation into allegations that she carried on an improper relationship with attorney David Reymann, who argued a major redistricting case before the very court on which she sat.
Hagen addressed her resignation letter to Gov. Spencer Cox, a Republican, writing that she was leaving "with deep sadness." She expressed regret for what she called the disruption her "sudden departure" would cause the court and the parties who come before it. But the disruption was already well underway before she signed the letter.
The allegations first surfaced roughly a month before the resignation. Reymann served as the former lead attorney for the League of Women Voters in Utah's redistricting battle, where he had argued that Republicans' proposed congressional maps were illegal. That case carried enormous political weight. And the claim that the justice who helped decide it had a personal relationship with one side's lead lawyer struck at the foundation of the ruling's legitimacy.
The timeline tells the story. Hagen stated that her last involvement in the redistricting case was in October 2024. By May 2025, she had voluntarily recused herself from all cases involving Reymann. She pointed to the court's September 15, 2025, opinion in the case as reflecting that recusal. But none of those steps quieted the questions about what happened before the recusal, and why it took so long.
Hagen had previously denied a conflict of interest. Fox News reported that her former husband accused her of sending inappropriate text messages to Reymann, and that the complaint was submitted to the chief justice and the Judicial Conduct Commission.
The Judicial Conduct Commission opened an independent investigation as a result of the complaint. But according to the New York Post, a preliminary review by the commission reportedly did not move forward, raising its own set of questions about whether the state's existing judicial oversight mechanisms were up to the task.
In April, Cox joined Utah House Speaker Mike Schultz and Utah Senate President J. Stuart Adams, both Republicans, in announcing a separate investigation into the allegations. That move signaled that the state's elected leaders were not content to let the matter die quietly inside an internal judicial process.
In her resignation letter, shared publicly via a social media post by journalist Robert Gehrke, Hagen mounted a careful defense of her record. She wrote:
"For the last three decades, I have worked to earn a reputation for professionalism, fairness, and integrity. Throughout my career as a prosecutor and over the last nine years on the bench, I have faithfully upheld my oath to the constitution and the ethical obligations that govern our profession."
She also said she would have preferred to stay. The Washington Examiner reported that Hagen wrote, "I would love nothing more than to continue serving the people of Utah," but said staying would require sacrificing the "privacy and well-being" of loved ones.
That framing cast the resignation as a personal sacrifice rather than a professional reckoning. But the facts point in a different direction. A justice on a state supreme court participated in deciding a politically charged redistricting case while allegedly maintaining a personal relationship with one party's lead attorney. She denied a conflict. A complaint was filed. An investigation was opened. Elected leaders launched their own probe. And only then did she step down.
The resignation of a justice at the center of a gerrymandering ruling doesn't just raise questions about one judge's conduct. It raises questions about the integrity of the ruling itself, and about whether the process that was supposed to catch this kind of conflict failed.
Gov. Cox and the Republican legislative leaders responded to the resignation with a joint statement. The Washington Times reported that Cox, Adams, Schultz, and Chief Justice Matthew Durrant said:
"We appreciate Justice Hagen's resignation and her willingness to step aside in the best interest of the institution."
But they did not stop there. The Republican leaders said they were "committed to working together on potential reforms to the Judicial Conduct Commission, ensuring it upholds the highest standards of accountability and earns the confidence of the people of Utah." That language pointed directly at the commission's handling of the initial complaint, which, by several accounts, did not result in decisive action before political pressure forced the issue.
The governor's decision to order a probe into a sitting justice was itself a remarkable step. Governors do not typically intervene in judicial conduct matters. That Cox, Schultz, and Adams felt compelled to act suggests they concluded the existing oversight structure was not going to hold the justice accountable on its own.
Just The News reported that Reymann had represented plaintiffs in a 2024 case in which Hagen struck down a constitutional amendment that would have allowed lawmakers to repeal ballot initiatives. That detail adds another layer: the justice's alleged personal entanglement was not with a lawyer in some minor procedural dispute. It was with the lead attorney in a case that reshaped the balance of power between Utah's legislature and its voters.
Hagen's immediate resignation creates a vacancy on Utah's five-member Supreme Court. Gov. Cox will now be responsible for filling the seat, a process that carries significant political stakes in a state where the court has already been at the center of a fierce redistricting fight.
The broader question of judicial vacancies and the political dynamics surrounding them is playing out at every level of the American court system. In Utah, the next appointment will be watched closely, not just for the nominee's qualifications, but for whether the replacement restores public confidence in a court that just lost a member under a cloud of ethical failure.
Officials indicated that Hagen's resignation effectively ends the immediate matter, but the push for Judicial Conduct Commission reform suggests the political fallout is far from over. If the commission's preliminary review truly stalled before elected leaders intervened, that raises a structural problem that one resignation does not fix.
The ongoing national debate over judicial turnover and the stakes of filling court seats only amplifies the significance of what happened in Utah. When judges leave the bench under pressure, whether at the state or federal level, the appointment that follows becomes a referendum on institutional credibility.
Hagen wrote that she had "faithfully upheld" her oath throughout her career. Perhaps she believes that. But an oath to the constitution includes an obligation to avoid even the appearance of impropriety, an obligation that, by the facts now on the public record, she failed to meet in a case of enormous consequence to Utah voters.
The redistricting case she sat on was not an abstraction. It determined how Utahns would be represented in Congress. The allegation that the justice deciding that case had a personal relationship with one side's attorney goes beyond embarrassment. It goes to whether the people of Utah got a fair hearing from their own Supreme Court.
Breitbart reported that the resignation came nearly a month after the allegations first surfaced, a month during which Hagen denied a conflict, the Judicial Conduct Commission opened and apparently stalled an investigation, and Republican leaders had to step in to demand accountability.
Hagen described her colleagues on the court as "brilliant jurists" and "dedicated, hard-working public servants." She may be right about them. But the standard for serving on a state's highest court is not brilliance or hard work alone. It is integrity, and the willingness to hold yourself to the same rules you enforce on everyone else.
When a judge won't do that, the system depends on someone else stepping in. In Utah, it took elected officials to do what the judicial oversight process apparently could not. That's a problem no resignation letter can fix.
