Court Revives GOP Missouri Map, Sends Case to Supreme Court

A federal appeals court on Monday reinstated a Republican-drawn congressional map in Missouri for the November midterms, handing President Donald Trump and his allies a fresh legal victory — but delaying the ruling’s effect until Sept. 28 to give opponents time to reach the U.S. Supreme Court.

The 8th U.S. Circuit Court of Appeals ruled that using the state’s older 2022 map for the Nov. 3 general election would violate the Constitution’s equal protection clause, because district lines had already been used in the August primary. The case now heads to the nation’s highest court for a possible third time in a dispute that could help shape which party controls the House of Representatives.

A Map Built to Flip a Seat

Missouri Republicans passed the new map in a September 2025 special session at Trump’s urging, joining GOP-led states such as Texas and Florida in redrawing district lines mid-decade — outside the normal 10-year census cycle — to protect the party’s slim House majority in the 2026 midterms.

The 2025 map targets Rep. Emanuel Cleaver, the Kansas City Democrat, by splitting his safely Democratic district into three rural-dominated districts. It would also make the St. Louis-area 2nd District more Republican-leaning for Rep. Ann Wagner. All told, the plan would favor Republicans in seven of Missouri’s eight House seats, up from the current 6-2 split, according to NBC News.

Opponents fought back through an unusual route: the referendum. The group People Not Politicians gathered more than 300,000 signatures to put the 2025 map to a public vote, which — under the Missouri Constitution — suspended the new lines pending a vote. That mechanism, unavailable to voters in several other GOP-led states, became the legal fault line between state and federal courts.

A Back-and-Forth Legal Battle

The dispute has swung repeatedly between the two court systems over the past month. The Missouri Supreme Court ruled that the referendum petition had effectively paused the 2025 map and that the 2022 lines governed the fall election. After Secretary of State Denny Hoskins initially defied that ruling, the state’s high court found him in contempt; he relented and directed local officials to use the 2022 map, and Chief Justice W. Brent Powell reversed the contempt finding after Hoskins, in the court’s words, “corrected his contemptuous conduct.”

Four GOP plaintiffs — including Rep. Bob Onder and state Sen. Rick Brattin — then sued in federal court. On Sept. 8, U.S. District Judge Stephen Clark issued an injunction reinstating the 2025 map, only for the full U.S. Supreme Court to stay that ruling two days later after Justice Brett Kavanaugh had earlier denied emergency relief to the state. The high court’s intervention appeared to settle the matter — until Monday’s appeals ruling reopened it.

In its unsigned, or per curiam, decision issued four days after a special hearing, the three-judge panel wrote that voters’ constitutional right to choose a member of Congress “requires continuity in the constituency throughout all stages of a single election.”

“Changing district lines between the primary and general election prevents an affected voter from participating in either district’s complete procedure of choice,” the panel held.

The panel comprised Judge James B. Loken, an appointee of George H.W. Bush, alongside two Trump appointees, Judges David R. Stras and Justin D. Smith, according to Courthouse News Service. Stras concurred in part and dissented in part, finding that People Not Politicians and its executive director, Richard von Glahn, lacked standing to appeal.

Courts Versus the Calendar

Compounding the legal uncertainty is a tightening calendar. Military and overseas absentee ballots were already sent out under the 2022 map on Sept. 19, and regular absentee voting began Tuesday. Because the appeals court stayed its own ruling until Sept. 28, the Missouri Supreme Court’s order requiring the 2022 map remains in effect in the interim.

Chuck Hatfield, an attorney for People Not Politicians, said he plans to appeal to the U.S. Supreme Court and expects it to stay the ruling.

“I think the Supreme Court of the United States has been pretty clear that the federal courts are prohibited from interfering in elections this close to Election Day,” Hatfield said, per St. Louis Public Radio. “Votes have already been cast by military members. Absentee balloting for those with excuses will start tomorrow.”

Election administrators described the prospect of changing maps mid-vote as unprecedented. Eric Fey, St. Louis County’s Democratic director of elections, said his office planned to mail more than 9,000 ballots to local voters starting Tuesday.

“I don’t know what if anything would happen with all the ballots that had been cast at that point … it’s unprecedented,” Fey said. “Don’t know how that would be handled, but for administrators at least it is the stuff of nightmares.”

Kurt Bahr, St. Charles County’s election director, said that if the Supreme Court ultimately sides with the 8th Circuit, residents who cast ballots in the 2nd Congressional District would have their votes counted in every race except Congress.

Onder framed the ruling as a defense of voters who participated in the August primary.

“The question is whether 1.2 million Missouri voters would be disenfranchised by an activist Missouri Supreme Court,” he said. “And I think today the 8th Circuit said no … I think it’s a big victory for democracy and for the rule of law.”

What’s Next

The appeals panel anticipated the complications, noting that while the situation is “uncommon,” it is “not unprecedented,” and that courts around the country have ordered ballot changes after absentee ballots were already distributed.

Yet the panel’s ruling faces long odds of taking effect before Nov. 3. As Roll Call reported, the Supreme Court has already twice declined to let the 2025 map proceed, and von Glahn said his group would file an emergency application to the high court.

“Ballots have been printed, and Missourians have already voted,” von Glahn said. “Thousands more will vote before this order seeks to take effect. Officials should stop wasting taxpayers’ money on pointless legal action and instead focus on administering our elections.”

With the Sept. 28 stay deadline looming, the dispute could be resolved — or deepened — within days. What the Supreme Court does next will determine not only which lines Missouri voters encounter at the polls, but also whether a state can change its congressional map between a primary and a general election at all — a question with implications for every mid-decade redistricting fight across the country.
