Supreme Court Rocked By Extramarital Affair – Justice Facing Removal

A complaint filed in December 2025 with Chief Justice Matthew Durrant and the Judicial Conduct Commission outlines allegations that Utah Supreme Court Justice Diana Hagen “failed to promote confidence in the judiciary” because she was “improperly influenced by external relationships.”

ABC4 obtained records showing the complaint came from a lawyer in Provo who said Hagen’s ex-husband told him she was having an affair with David Reymann, an attorney involved in the high-profile congressional redistricting case.

The complaint raises concerns that Justice Hagen may not have been able to remain impartial in the matter because of the alleged relationship.

Justice Hagen responded in a letter to the Utah Judicial Conduct Commission after learning of the claims. She strongly denied the accusations, writing, “The suggestion that I was morally compromised while doing my official duties is completely false.”

Hagen said her last involvement in the redistricting case was in October 2024. According to the letter, after her thirty-year marriage ended in the spring of 2025, she reconnected with friends, including Reymann, for emotional support.

Hagen also stated that after reconnecting with Reymann, she chose not to participate in any cases involving him, including a later petition in the redistricting matter.

Tobin Hagen, her ex-husband, said in an interview on January 15, 2026, that he believes the Justice had an affair with Reymann based on the circumstances.

He acknowledged he has no direct proof of the affair. He also said he could not share copies of text messages between Hagen and Reymann that he claims were inappropriate and suggestive because both parties signed a non-disparagement agreement as part of their 2025 divorce.

In a joint statement, Spencer J. Cox, J. Stuart Adams, and Mike Schultz said they plan to move forward with an independent investigation, arguing that the Judicial Conduct Commission and the Court’s initial report left unanswered questions.

In response, Democratic leaders in the Utah Senate and House issued a statement expressing concern that lawmakers were exceeding constitutional boundaries and threatening judicial independence.

In a statement, the Utah Supreme Court said Justice Hagen’s final involvement in the League of Women Voters case was in October 2024 and that her ex-husband’s accusations surfaced after she had already left the case.

Addressing the investigation, the court added, “As the sole entity authorized to investigate allegations of misconduct against a judge, the Judicial Conduct Commission received the allegations in their entirety and conducted an independent investigation. The Judicial Conduct Commission completed their investigation in accordance with their constitutional and statutory authority and dismissed the complaint against Justice Hagen.”

The court also said records from the Judicial Conduct Commission were “inappropriately released to the public” and noted that complaints and related proceedings are legally confidential.

A spokesperson for the Judicial Conduct Commission said its chair, who had ties to the law firm involved, also recused herself. The commission declined further comment.

State leaders did not provide a timeline for the new investigation or identify who would conduct the review.

Justice Hagen was appointed to the Utah Supreme Court in 2022 by Spencer J. Cox. She previously served on the Utah Court of Appeals and worked in private practice and federal prosecution.
