2018 Utah Proposition 4

The proposition created by statute an independent redistricting commission in the state, a measure to avoid gerrymandering.

The closeness of the result was hypothesized to be due to Republicans, the dominant party in Utah, voting against the proposition to maintain their total control over redistricting.

In particular, the congressional map approved by the legislature redesigned the congressional representation of Salt Lake County, with all four districts extending from Salt Lake County to the rest of the state.

Senate Bill 200 was challenged in state court on the grounds that it had violated the voters' intent in voting for Proposition 4.

On July 11, 2024, the Utah Supreme Court sided with the plaintiffs in League of Women Voters v. Utah State Legislature, ruling that the legislature had overstepped their constitutional authority in passing SB200.
