The U.S. Supreme Court shut down Missouri's Republican-drawn congressional map with no public dissents, the second time the justices have refused to let the state use districts that would have handed the GOP a seventh House seat.
The Court issued a brief, unsigned stay on Thursday blocking a federal judge's order that had briefly restored the 2025 redistricting lines. The ruling came just one day after the plaintiff group People Not Politicians filed an emergency petition, and it caps a week in which Missouri's congressional map changed three separate times. The state must now revert to the districts drawn after the 2020 census, lines that give Republicans a 6-2 advantage rather than the 7-1 edge the new map was designed to deliver.
The decision lands weeks before the midterm elections and affects more than one million voters, roughly one in four across the state, AP News reported. It also marks a sharp rebuke to Missouri Secretary of State Denny Hoskins, who had openly defied the Missouri Supreme Court's earlier order and directed local election officials to use the new map instead.
The chaos traces back to a redistricting plan passed last year that redrew Missouri's congressional boundaries to weaken the Democratic hold on Kansas City's 5th Congressional District. Opponents collected more than 300,000 signatures to put the map to a public referendum on the November ballot. Hoskins refused to place the referendum on the ballot, arguing that redistricting could not be decided by voter referendum.
People Not Politicians, the group behind the petition drive, took the fight to court. The Missouri Supreme Court sided with them, ruling that the new districts had never legally taken effect and ordering the state to use the 2022 map for the fall elections.
Hoskins did not comply. On Tuesday, he told county election officials to follow a conflicting ruling from Federal Judge Stephen R. Clark, who had found that Missouri could use the redrawn lines. That created an extraordinary standoff: two courts, two maps, and a secretary of state choosing which order to obey. The Missouri Supreme Court summoned Hoskins to explain why he should not be held in contempt.
The contempt question did not stay theoretical for long. AP News reported that the state Supreme Court found Hoskins in contempt for initially defying its order, though he ultimately complied after the U.S. Supreme Court stepped in Thursday.
Thursday's stay was not the justices' first involvement. Earlier in the dispute, Missouri appealed the state Supreme Court's ruling directly to the U.S. Supreme Court. Justice Brett Kavanaugh, who oversees the relevant circuit, rejected that appeal and kicked the case back to the state, deferring to the Missouri Supreme Court's conclusion that the new districts never became law.
When Judge Clark's federal ruling briefly revived the map, People Not Politicians went back to the high court on Wednesday seeking emergency relief. The full Court responded within a day, granting the stay in an order that carried no explanation and no noted dissents.
That unanimity surprised Republicans who had expected at least some of the Court's conservative justices to side with the state. The New York Post reported that the lack of any public dissent shocked GOP operatives who had counted on a friendlier reception.
The Trump administration had backed the redrawn lines, and the ruling amounts to a setback for broader Republican mid-decade redistricting efforts. But the Court's decision rested on procedural ground, whether the new map had ever legally taken effect, rather than on the merits of the district boundaries themselves.
Missouri already held its primary elections using the 2025 map. Candidates ran, voters cast ballots, and results were certified under district lines the Supreme Court has now blocked twice. The state must figure out how to run the general election under different boundaries than the ones used for the primaries, a logistical headache with no obvious precedent.
Richard von Glahn, executive director of People Not Politicians Missouri, framed the ruling as vindication. As UPI reported, von Glahn said in a statement:
"The law is the law, the Missouri Constitution is clear as was the Missouri Supreme Court."
RNC Election Integrity Communications Director Ally Triolo pushed back sharply, telling the Washington Examiner:
"After repeated legal victories defending Missouri's fair and lawful map, this 11th-hour ruling pulls the rug out from under voters who already cast their primary ballots."
Triolo's complaint highlights a real tension. Voters participated in a primary under one set of lines. Now they head into November under a different set. Whether that confusion falls on the courts that blocked the map or on the officials who pushed it forward despite unresolved legal challenges depends on where you stand, but the voters themselves did not create the mess.
The Trump administration has been active at the Supreme Court on multiple election-related fronts this cycle. It has separately asked the justices to restore access to federal voter verification databases and has filed repeated appeals on mail ballot rules, all part of a broader push to tighten election administration ahead of the midterms.
The Associated Press called Thursday's decision what appears to be "the end of the push to use the 2025 redistricting map." With the Supreme Court unanimously declining to intervene, twice, and with the state's own high court holding firm, there is no obvious legal avenue left for supporters of the redrawn lines before November.
Missouri's congressional delegation will compete under the 2022 boundaries: six Republican-leaning seats and two Democratic-leaning seats. The 7-1 advantage Republicans sought is off the table.
The Court has also been busy on other pre-election matters, recently blocking a Fourth Circuit ruling to preserve lower TV ad rates for political parties ahead of the midterms, a reminder that the justices are handling a heavy election-season docket with real consequences for both sides.
Several open questions remain. The contempt proceedings against Hoskins could carry their own consequences. The referendum on the 2025 map may still appear on the November ballot, meaning voters could weigh in on districts that are already blocked. And the broader question of whether states can redraw congressional lines mid-decade, outside the normal post-census cycle, remains unresolved nationally.
The administration has also sought Supreme Court approval for mail-in voting restrictions ahead of the 2026 elections, underscoring how many election-law battles are converging at the high court simultaneously.
When a secretary of state picks which court order to follow and the Supreme Court has to step in twice to settle the matter, the system has not worked the way it is supposed to. Missouri's voters deserve better than a map that changes three times in a single week.
