Overview
- Judge Dianna Gibson rejected the Legislature’s “Map C,” finding it relied on partisan data, unduly favored Republicans, and violated Proposition 4; she also blocked a recently passed redistricting law.
- The court adopted the plaintiffs’ “Map 1,” drawn by the League of Women Voters of Utah and Mormon Women for Ethical Government, creating a Democratic-leaning district anchored in Salt Lake County.
- The ruling was issued just before a Nov. 10 cutoff that Lt. Gov. Deidre Henderson set so county clerks can prepare for the 2026 election cycle.
- Republican leaders denounced the decision as judicial overreach, signaled appeals, and state Rep. Matt MacPherson opened an impeachment bill targeting Gibson.
- The outcome injects Utah into a broader mid-decade redistricting fight, as Trump-aligned Republicans and Democrats pursue new maps that could shape control of the U.S. House in 2026.
