A complaint has been filed by a Provo-based attorney alleging that Supreme Court Justice Diana Hagen failed to promote confidence in the judiciary due to being influenced by external relationships. The complaint was sent to both Chief Justice Matthew Durrant and the Judicial Conduct Commission in December 2025. Hagen denies the allegations, stating that her last involvement in the redistricting case was in October 2024. The Utah Supreme Court confirmed that Hagen's ex-husband's allegations post-date her involvement. An independent investigation into the allegations is pending. The governor, president, and legislative leaders have expressed concerns about potentially overstepping the independence of the judiciary.
