The Once-a-Decade Redraw
Every ten years, after the U.S. Census counts every person in the country, states redraw their electoral maps for Congress and the state legislature. The goal is to ensure each district has a roughly equal population, a principle often called 'one person, one vote'. Because populations shift—some areas grow faster than others—this redistricting process is essential for maintaining balanced representation. In Utah, this task has historically fallen to the state legislature, which, like in many states, means the party in power gets to hold the pen. This can lead to accusations of 'gerrymandering', the practice of drawing maps to unfairly benefit one political party.
Enter the People's Commission
In 2018, a feeling that the system was prone to gerrymandering led Utah voters
to narrowly approve Proposition 4. This citizen-led initiative created the Utah Independent Redistricting Commission (UIRC), a seven-member body designed to take the initial map-drawing process out of the hands of partisan politicians. The commission's members are appointed by the governor and legislative leaders from both parties, and it was barred from including lobbyists or recent candidates. Its mandate was to create maps based on neutral criteria like keeping communities and counties together and avoiding partisan bias.
The Commission at Work, The Legislature's Choice
Here's where the process gets complicated. Before the commission could even draw its first maps after the 2020 Census, the Utah Legislature passed a new law, SB 200, that significantly changed the rules. This bill effectively demoted the UIRC to a purely advisory role. While the commission still held public hearings and proposed a slate of maps based on its neutral criteria, the legislature was no longer bound to even explain why it might reject them. And that’s exactly what happened. In November 2021, the legislature’s redistricting committee ignored the UIRC's proposals and, in a special session, passed its own set of maps, which Governor Spencer Cox quickly signed into law.
The 'Pizza Slice' and a Legal Battle
The legislature's final map drew immediate criticism, particularly for how it handled Salt Lake County, the state's most populous and politically Democratic-leaning area. The map 'cracked' the county into four separate congressional districts, each stretching into more rural, conservative parts of the state. Critics dubbed this the 'pizza slice' approach, arguing it was a textbook case of partisan gerrymandering designed to dilute the votes of Salt Lake County residents and ensure all four of Utah's congressional seats remained safely Republican. This led to a lawsuit filed by the League of Women Voters of Utah and other groups, arguing the legislature had not only created an illegal partisan gerrymander but had also unconstitutionally overridden the will of the people expressed in Proposition 4.
The Courts Step In
The legal fight has been a roller coaster. After years of litigation, the Utah Supreme Court ruled in July 2024 that the legislature could not simply gut a voter-approved initiative. This sent the case back to a lower court, where in August 2025, a judge struck down the legislature's 2021 congressional map as unlawful. The court found that by repealing the core tenets of Proposition 4, the legislature had violated the state constitution. After further legislative attempts to pass a new map were also rejected by the courts, a judge ultimately selected a new congressional map for the 2026 elections, restoring a single unified district for most of Salt Lake County.
