Utah Supreme Court Justice Diana Hagen, who was involved in deciding Utah’s redistricting case, resigned her position with immediate effect Friday, following an announced investigation into an alleged workplace relationship that could represent a conflict of interest, according to reports.
Hagen submitted her resignation letter to Republican Utah Gov. Spencer Cox, who stated that the resignation was “effective immediately” and thanked her for her service to the state, according to a brief statement from Cox’s office.
Hagen expressed sadness over her resignation and regret over the suddenness of the resignation and the disruption that could result, the letter, shared by the Salt Lake Tribune journalist Robert Gehrke, revealed.
“[M]y family and friends did not choose public life,” Hagen wrote in her resignation letter. “They do not deserve to have intensely personal details surrounding the painful dissolution of my thirty-year marriage subjected to public scrutiny.”
Hagen added that she could not continue to serve the state “without sacrificing the privacy and well-being of those I care about and the effective functioning and independence of Utah’s judiciary,” according to the letter.
Hagen’s resignation comes after Cox, Republican House Speaker Mike Schultz and Republican Senate President J. Stuart Adams announced in April that there would be an investigation into an allegation that Hagen was improperly involved with David Reymann, an attorney in Utah’s redistricting case, the Salt Lake Tribune reported.

Reymann represented the League of Women Voters of Utah, one of the groups of plaintiffs that alleged the Republicans’ congressional map proposals were illegal, KUTV reported.
The Utah legislature had attempted to downgrade and set aside the citizen-approved proposition for an independent commission to draw the state’s congressional maps, KSL.com reported. The legislature attempted to amend the state’s constitution to grant lawmakers power to repeal the proposition, the Salt Lake Tribune reported.
The state’s Supreme Court nullified the state legislature’s moves in 2024. Gibson ruled that the state’s 2021 congressional map had to be redrawn. Hagen wrote an opinion for the court in that case, according to the Salt Lake Tribune.
Hagen’s ex-husband reportedly made the allegation of improper relationship between Hagen and Reymann through an attorney to the bipartisan Judicial Conduct Commission (JCC) in December 2025. The JCC investigated the allegation and decided that it was “speculative, overstated, and misleading” and had “very little credibility,” the outlet reported.
State leaders pushed for additional investigation.
The state’s Supreme Court said that Hagen had last involved herself in the redistricting case in October 2024 and had recused herself from the case “after she reconnected with a number of old friends in the spring of 2025,” according to 2KUTV.
“Her ex-husband’s allegations postdate her involvement in League of Women Voters,” the Court said in part.
Hagen also denied working under any conflict of interest and said she reported herself to the JCC and submitted a sworn statement.
