Missouri Court Blocks GOP Redistricting Map, Orders November Referendum

Missouri voters will decide the fate of new congressional districts after the state Supreme Court ruled that a Republican-backed map cannot take effect for the November midterms without approval in a statewide referendum. The decision keeps the boundaries drawn after the 2020 census in place for the 2026 elections and preserves the current 6-2 Republican majority in the state’s U.S. House delegation.

The court found that a citizen petition seeking the referendum met all legal requirements. “The referendum petition was legal, sufficient, and timely, and the secretary incorrectly concluded otherwise,” the ruling stated. The legislation containing the new districts “did not go into effect and will not go into effect unless and until approved by the voters.” The 2020 map therefore remains in force.

Missouri’s General Assembly passed the redistricting bill in September 2025. Organizers submitted more than 300,000 signatures the following month. In August the secretary of state issued a certificate of insufficiency, prompting lawsuits that reached the Supreme Court. The court reversed a lower-court decision and directed the secretary to certify the petition for the November ballot.

Republican officials immediately signaled further legal action. Attorney General Catherine Hanaway said the state would appeal to the U.S. Supreme Court, describing the ruling as an unprecedented intervention that created a constitutional crisis and would disenfranchise voters. Governor Mike Kehoe called the decision a lack of respect for the legislative process by unelected judges.

Former President Trump posted on Truth Social that the ruling was “horrible, ridiculous and unConstitutional” and left insufficient time to restore the prior map before the election. Democratic U.S. Representative Emanuel Cleaver, whose Kansas City district had been altered under the new lines, said the people had prevailed against an attempt to silence neighbors. Richard von Glahn of People Not Politicians stated that the constitution’s words matter and that voters would have the final say.

The ruling occurs amid parallel redistricting efforts in other states. A Maryland Supreme Court decision the same day allowed a Democratic-backed constitutional amendment on congressional districts to appear on that state’s November ballot, though with revised wording. Those proceedings remain separate from Missouri’s case.
