Supreme Court Halts GOP-Drawn Missouri Map, Restoring Democratic-Leaning District for November

The U.S. Supreme Court on Thursday froze a federal judge's order that would have forced Missouri to use a newly drawn, Republican-favored congressional map in November, effectively ending a five-day collision between state and federal courts over which district lines will govern the state's midterm election.

In a one-paragraph, unsigned order issued Thursday in People Not Politicians v. Onder, the justices granted an emergency stay application referred to the full court by Justice Brett Kavanaugh, halting a September 8 ruling by Chief U.S. District Judge Stephen Clark that had ordered Missouri to use the 2025 map, known as HB 1, for the general election. The stay holds while an appeal proceeds at the U.S. Court of Appeals for the 8th Circuit and while the losing side decides whether to ask the full Supreme Court to hear the case on the merits.

The practical effect, state officials said Thursday, is that Missouri will use the congressional boundaries adopted in 2022 — not the 2025 map drawn to eliminate a Kansas City-area Democratic seat — when voters cast ballots on November 3.

The numbers

Missouri's eight-member U.S. House delegation currently splits 6-2 in favor of Republicans under the 2022 map. The 2025 map, passed by the GOP-controlled legislature and signed by Gov. Mike Kehoe, redrew the Kansas City-based 5th District held by Democratic Rep. Emanuel Cleaver, a move designed to push the delegation to a 7-1 Republican advantage. Opponents of the new map, organized as People Not Politicians and led by Richard von Glahn, gathered more than 300,000 signatures by December 9, 2025, to force a statewide referendum on HB 1 — comfortably above the roughly 106,000 signatures Missouri's constitution requires to suspend a law pending a public vote. The Supreme Court's order carries no recorded dissent.

How the dispute reached the justices

Missouri lawmakers approved the new map in a special legislative push in 2025, part of a broader mid-decade redistricting wave in Republican-controlled states encouraged by President Trump to protect the House majority ahead of the midterms. Because Missouri's constitution allows citizens to suspend a law by referendum once enough signatures are certified, von Glahn's group argued HB 1 never took legal effect. On September 3, the Missouri Supreme Court agreed in a unanimous opinion in Von Glahn v. Hoskins, ordering Secretary of State Denny Hoskins to certify the referendum petition and holding that the 2022 map remained the only valid one on the books.

"HB 1 is not the law and has never been the law. There is only one valid congressional redistricting in effect — the congressional redistricting the General Assembly established in 2022," the Missouri Supreme Court wrote in its September 3 opinion.

Republican candidates, including Reps. Bob Onder and Rick Brattin, responded by suing in federal court, arguing in Onder v. State of Missouri that switching maps after the state's August 4 primary — which had been conducted under HB 1's district lines — would violate federal election-administration law and confuse voters and candidates alike. Hoskins separately asked the Supreme Court to pause the state ruling directly; Justice Kavanaugh denied that application on September 8. Hours later, Judge Clark granted the Republican candidates' request for a temporary restraining order compelling use of the 2025 map. Hoskins then instructed county election authorities to follow Clark's order, prompting Missouri Supreme Court Chief Justice W. Brent Powell to direct Hoskins to appear in person and explain why he should not be held in contempt for defying the state court's mandate. A three-judge panel of the 8th Circuit declined on September 9 to block Clark's order, and People Not Politicians turned back to the Supreme Court with the emergency application the justices granted Thursday.

Who is affected

The most immediate stakes fall on Cleaver, the 12-term Kansas City Democrat whose 5th District the 2025 map had reconfigured to add heavily Republican suburban and rural precincts. Under the 2022 lines now back in force, his seat remains the delegation's lone reliably Democratic district alongside St. Louis-area Rep. Wesley Bell's. Candidates who campaigned over the summer under HB 1's altered boundaries will now run in November under the 2022 map's district numbers and boundaries, a mismatch local election officials have said they are prepared to manage. Missouri voters more broadly face a ballot question this cycle, since the September 3 ruling also sent HB 1 itself to a statewide referendum vote, meaning residents will separately decide whether to ratify the 2025 map for future elections even as the 2022 map governs this one.

Reaction

Hoskins, a Republican who had pushed to implement the 2025 map, told reporters Thursday afternoon that his office would comply with the high court's order. "Following the United States Supreme Court's stay, the only governing court order in effect is from the Missouri Supreme Court," he said, according to ABC 17 News. Missouri Attorney General Catherine Hanaway backed the shift, saying her office affirmed "the Secretary of State's position and decision to advise local election authorities that the 2022 map is in effect." Powell subsequently found that Hoskins had "purged himself" of the contempt allegation by notifying local officials of the change.

Chuck Hatfield, the attorney representing People Not Politicians, framed the outcome as a test of institutional compliance rather than simply a partisan win. "The whole system kind of wins," he said, according to Roll Call. "Are we going to follow the law? When the Supreme Court speaks 7 to 0, are the officials in the state going to follow that direction?" Cleaver, whose district was the map's central target, credited grassroots organizing for the outcome, telling reporters "the people here did something that I think will end up in the textbook on community engagement." Not every Democrat was satisfied with how the fight unfolded: state Sen. Russ Carnahan criticized the week's dueling rulings as "confusing" and damaging to public trust in elections. Gov. Kehoe, whose administration championed the 2025 map, said he still expects vindication on the merits, telling reporters he looks "forward to the 8th Circuit's consideration of the merits of the Missouri First map."

What happens next

Thursday's stay is explicit that it is temporary rather than a final resolution. It remains in place only until the 8th Circuit rules on Missouri's appeal of Judge Clark's order and, if a petition for Supreme Court review follows, until that petition is resolved; should the justices decline to hear the case, the stay automatically lapses. The 8th Circuit has scheduled oral argument for September 17, and legal observers following the case, including at Law Dork, expect the panel's ruling to shape whether the map fight resurfaces before Election Day or is pushed to a future cycle. Separately, the referendum on HB 1 itself remains on course to appear on the November ballot, meaning Missouri voters will register their own verdict on the 2025 map even as the courts continue arguing over which lines apply this year. For now, election officials across the state's 116 counties are proceeding on the assumption that the 2022 map is final for 2026, an assumption that, given the week's whiplash, several have said they are treating with caution until the 8th Circuit weighs in.
