A Utah Supreme Court judge has resigned from the bench over claims from her ex-husband that she exchanged 'inappropriate text messages' with an attorney. 

Diana Hagen stepped down on Friday amid affair allegations with a redistricting lawyer who was working on a case in front of the high court. 

Tobin Hagen filed a complaint last year with the Judicial Conduct Commission, naming lawyer David Reymann as his ex-wife's alleged lover.

According to Tobin, texts between the pair began as 'silly' and soon became 'more suggestive.' 

At the time, Reymann and Hagen denied any involvement with one another, per Fox13. 

The commission conducted a preliminary investigation but chose not to dive deeper after dismissing allegations as 'misleading,' reported the Salt Lake Tribune. 

But Republican lawmakers, Senate President J Stuart Adams and House Speaker Mike Schultz, renewed demands that Hagen's alleged affair be investigated, seemingly prompting her resignation.

In her resignation letter, tendered to Utah Governor Spencer Cox, Hagen alluded to her alleged involvement with Reymann and the 'dissolution' of her marriage.

'As a public servant for twenty-six years, I am keenly aware that public service requires sacrifice,' Hagen said in the letter obtained by Fox Digital. 

'I have willingly accepted those sacrifices for the privilege of holding a position of public trust, where I could do my part to uphold the rule of law and protect the rights of every Utahn.

'I also understand that public officials are rightly held to a higher standard and must accept a greater degree of public scrutiny and diminished privacy,' she said. 'But my family and friends did not choose public life. 

They do not deserve to have intensely personal details surrounding the painful dissolution of my thirty-year marriage subjected to public scrutiny.' 

Adams and Schultz subsequently dropped their demands for an investigation. 

'We appreciate Justice Hagen's resignation and her willingness to step aside in the best interest of the Institution,' they wrote in a joint statement. 

'We consider this matter related to Justice Hagen concluded and will not conduct any further investigations related to these specific allegations.'

Governor Cox announced Hagen's resignation in a press release. The governor is tasked with appointing her replacement. 

'Today, Gov. Cox received a letter of resignation from Utah Supreme Court Justice Diana Hagen,' it read. 

'The resignation is effective immediately. The governor appreciates Justice Hagen’s years of service to the state of Utah.'

Hagen was appointed to the Utah Supreme Court by Cox in 2022, according to her profile, which is still live on the Utah Courts webpage. 

Tobin Hagen told the Judicial Conduct Commission that the couple's marriage began 'deteriorating' at the end of 2024.

Justice Hagen allegedly requested a divorce in September 2024, just before the couple first interacted with Reymann.

The scorned husband claimed to have found 'inappropriate text messages' in February 2025.

At the time, Reymann was challenging a redistricting map before the Supreme Court that retained four Republican-districted seats in Utah. 

The case led to a new congressional map, reported KSL.

Hagen and her husband separated in April 2025. She 'voluntarily recused' herself from the redistricting case a month later. 

The recusal notice noted that Hagen had recently 'renewed friendship' with Reymann.

Hagen has claimed she 'never engaged in extramarital sex with anyone prior to our separation.'

The Daily Mail contacted Cox, Hagen, Reymann and the Utah Supreme Court for comment.
