Overview
- Third District Judge Dianna Gibson selected Plaintiffs’ Map 1, proposed by the League of Women Voters of Utah and Mormon Women for Ethical Government, for the 2026 congressional elections.
- Her ruling found the Legislature’s Map C used partisan data, violated Proposition 4’s criteria, and unduly favored Republicans over Democrats.
- Gibson also enjoined S.B. 1011, writing that its partisan-symmetry tests effectively mandated favoritism prohibited by Proposition 4.
- The chosen map keeps Salt Lake County largely intact to create a Democratic-leaning district, improving Democrats’ chances to flip a U.S. House seat in 2026.
- The decision was issued just before the Nov. 10 administrative deadline set by Lt. Gov. Deidre Henderson, as GOP leaders prepare appeals and one legislator announced an impeachment push against the judge.
