The United States Supreme Court has ordered Missouri to use its 2022 congressional map for the 2026 elections rather than a newly drawn 2025 map, in an unsigned ruling with no noted dissents. The decision blocks what could have been a map favourable to the Republican Party and effectively halts the immediate legal dispute over which boundaries the state should use for the forthcoming midterm elections. The court made clear that neither lower courts nor the state should use the newer 2025 map.

The Supreme Court's order explicitly instructed lower courts to neither prohibit the use of the 2022 map nor require Missouri to use the 2025 version. This ruling leaves Missouri's older congressional boundaries in place, settling a redistricting dispute that had created legal uncertainty about the state's electoral framework. The decision represents a significant moment in ongoing redistricting litigation and prevents the state from adopting boundaries that would have altered the political landscape.
