A complaint filed in December 2025 with Chief Justice Matthew Durrant and the Judicial Conduct Commission details 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 that show the complaint came from a lawyer in Provo who was told by Hagen’s ex-husband that she was having an affair with David Reymann, the lawyer for the high-profile congressional redistricting case.
The complaint suggests that Justice Hagen might not be able to be fair in the case because of the alleged affair.
Justice Hagen wrote a letter to the Utah Judicial Conduct Commission after hearing about the claims. Hagen strongly denies the claims of cheating, saying, “The suggestion that I was morally compromised while doing my official duties is completely false.”
Justice Hagen says that her last involvement in the redistricting case was in October 2024
Justice Hagen says that her last involvement in the redistricting case was in October 2024. The letter says that after her thirty-year marriage ended in the spring of 2025, Hagen got back in touch with friends, including the Reymann, for emotional support.
Hagen also said that after she got back in touch with Reymann, she chose not to work on any cases he was involved in, including a later petition in the redistricting case.
Tobin Hagen, Hagen’s ex-husband, said in an interview on January 15, 2026, that he thinks the Justice had an affair with Reymann only because of the circumstances.
He doesn’t have any direct proof that the affair happened
He doesn’t have any direct proof that the affair happened. He can’t share the copies of the text messages he has between Hagen and Reymann that he says are inappropriate and suggestive because they signed a non-disparagement agreement as part of their divorce in 2025.
In a joint statement, Governor Spencer J. Cox, President J. Stuart Adams, and Speaker Mike Schultz stated that they plan to proceed with an independent investigation because the Judicial Conduct Commission and Court’s initial report left questions unanswered.
In response to the Legislature, the Democratic Leaders of the Utah Senate and House issued a statement voicing concerns that they are going beyond the bounds of constitutional procedures and the independence of the judiciary.
In a statement, the Utah Supreme Court stated that Justice Hagen’s last involvement in the League of Women Voters case was in October 2024 and that her ex husband’s accusations were made after she had left the case

Regarding their investigation into the allegations against Hagen, the Utah Supreme Court stated, “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.”
Additionally, they claim that the Judicial Conduct Commission’s records were “inappropriately released to the public” and that the complaint and its proceedings are legally confidential.
The commission declined to comment further on the matter
A spokesperson for the Judicial Conduct Commission said its chair, who is connected to the law firm involved, also recused herself. The commission declined to comment further on the matter.
State leaders did not provide a timeline for the new investigation. They also did not specify who would conduct the review.
Hagen was appointed to the Utah Supreme Court in 2022 by Cox. She previously served on the Utah Court of Appeals and worked in private practice and federal prosecution.
