Supreme Court Rejects Missouri Redraw, Keeps Primary Map for November
The U.S. Supreme Court on Sept. 25, 2026, rejected a Republican-backed effort to redraw congressional seats in Missouri.
The matter is docketed as No. 26A388, People Not Politicians v. Onder. The action preserves a key U.S. House seat for Democrats NPR.
The case centers on Missouri's 2025 congressional redistricting map. Redistricting is the redrawing of boundary lines for House districts. The Missouri Supreme Court ruled that the 2025 map is not the law and will not take effect U.S. Supreme Court. An order in the litigation requires Missouri to use for the general election the same congressional map it used in the primary election.
That directive controls the November election. Missouri is poised to revert to its former congressional districts. A state election official ordered the old map to be used instead of the Trump-backed map for November.
The map at issue was backed by President Donald Trump. The Supreme Court rejection was the third time it turned away the Trump-backed Missouri map.
The sequence moved through state and federal courts in September. On Sept. 8, 2026, the U.S. Supreme Court declined to reinstate the Republican-drawn congressional map Reuters. Justice Kavanaugh issued a decision in the Missouri redistricting litigation.
A federal court in Missouri temporarily blocked the older congressional map from being used in the hours after Justice Kavanaugh's decision. An appeals court then ruled in favor of the Trump-backed Missouri map. The U.S. Supreme Court had the final say following that appeals court ruling.
The fight also played out outside the courtroom. Citizens turned in thousands of petition signatures opposing the new Trump-backed Missouri map.
Procedurally, the Supreme Court publishes Orders of the Court for Term Year 2025 on its official website. The Term Year 2025 orders page lists a Miscellaneous Order dated Sept. 23, 2026, and an Order List dated Sept. 4, 2026. The Court issues scheduled order lists on each Monday it sits and may issue miscellaneous orders in individual cases at any time. It posts scheduled order lists online on the day of issuance and posts miscellaneous orders on the day of issuance or the next day.
The immediate result is continuity. Voters will cast ballots under the same district lines in the general as in the primary. Election administrators avoid a late switch. Litigants lose the redrawn lines for this cycle.
Looking at what this means for control of the House, the Missouri decision could boost Democrats' effort to win the U.S. House in the midterm elections. Practitioners watch these stay fights closely because timing often decides the map. A ruling that freezes lines in September effectively settles November. Late relief is rare. Courts weigh disorder against legal claims, and the status quo tends to hold once ballots are prepared.
The broader context here is the national redistricting calendar colliding with federal review. State supreme court rulings on whether a new map is law, federal district court injunctions on which map may be used, circuit rulings reviving a map, and emergency applications to the justices now form a familiar chain. Each link narrows the next. By the third application, the question is less about the underlying redistricting theory than about which order governs the imminent election. In Missouri, the answer is the primary map.
