A Utah Supreme Court justice has resigned because of an investigation into her relationship with a lawyer who worked on a case about voting areas.

Justice Diana Hagen wrote a letter to Utah Governor Spencer Cox, which Fox News Digital got, and it seems like she's talking about the investigation and how it's affecting her loved ones.

Justice Hagen said that being a public servant means making sacrifices, and she's okay with that because she wants to uphold the law and protect people's rights.

Utah leaders started an investigation into a Supreme Court justice because of her alleged relationship with a redistricting lawyer.

Justice Hagen said that public officials are held to a higher standard and must accept more public scrutiny, but her family and friends didn't choose this life and don't deserve to have their personal details made public.

The resignation was effective immediately, according to a spokesperson for Utah's Administrative Office of the Courts.

Justice Hagen was accused by her ex-husband of sending inappropriate text messages to a lawyer who worked on a case about voting areas, and this lawyer, David Reymann, was named in a complaint to the Judicial Conduct Commission.

A judge in a red state chose a new map for Congress, which could change who controls the House.

Hagen and the lawyer, Reymann, denied the allegations before.

The Judicial Conduct Commission did a preliminary investigation and decided not to pursue the matter further, according to KSL.

The Utah Supreme Court said in a statement that Justice Hagen took prompt and transparent steps in response to the allegations.

Justice Hagen said she hadn't been involved in the redistricting case since October 2024 and had recused herself from cases involving the lawyer, Reymann, in May 2025.

In her resignation letter, Justice Hagen said she would love to keep serving on the bench.

Justice Hagen said she can't keep serving without hurting the people she cares about and the independence of Utah's judiciary.

The governor will choose Justice Hagen's replacement, and Fox News Digital has reached out to the governor's office.
