Missouri Lawmaker Files Lawsuit to Overturn State Supreme Court's Redistricting Block

In a move that’s already stirring up a lot of talk on both sides of the aisle, Rep. Bob Onder (R‑Mo.) lodged a lawsuit on Friday seeking to reverse a Missouri Supreme Court decision that blocked a new, Republican‑leaning congressional map. The filing, joined by GOP House hopeful Rick Brattin and two ordinary Missourians, landed in the U.S. District Court for the Eastern District of Missouri.

“It felt like a startling act of judicial supremacy,” Onder told The New York Post. He went on to explain that the high court’s order came after more than 1.2 million primary voters had already cast ballots for their preferred candidates—Republicans, Democrats, Libertarians and Greens alike. “When the court tried to toss out the map after the primaries, it effectively disenfranchised those voters,” he said, his voice tinged with frustration.

The lawsuit argues that the state Supreme Court’s move violates both the U.S. Constitution and the Missouri Constitution. According to the complaint, reinstating the old district lines for the Nov. 3 general election would be “costly, confusing, and burdensome” for voters, candidates and election officials alike. “They completely threw the election process into disarray,” Onder added, pointing to the logistical nightmare of reshuffling ballots just weeks before Election Day.

Under the disputed map, the 5th District—a seat held by Democrat Rep. Emanuel Cleaver—would become more favorable to Republicans, paving the way for Brattin’s challenge. The state Supreme Court, however, halted the map after a petition drive forced a statewide referendum on the new boundaries. In a unanimous decision, the justices ordered that Missourians vote in November on whether the map should stand.

“Primary voters chose the Republican and the Democrat nominee, and all of a sudden you’re just going to scramble those various nominees and have them run in different districts? It just makes utterly no sense whatsoever,” Onder fumed. He said he’s been fielding texts from constituents who’re bewildered: “I was looking forward to having you as my congressman… I voted for you in August. What happens now?”

Missouri’s Republican Attorney General, Catherine Hanaway, is not waiting for the district court’s outcome. She filed an emergency request with the U.S. Supreme Court, urging the high court to step in before the November vote. “We look forward to the Supreme Court’s prompt review of this critical matter, as our ability to hold timely and lawful congressional elections hangs in the balance,” she wrote on X.

Onder, meanwhile, invoked a “long line of precedents” that warn against meddling with elections close to the ballot. “There’s a precedent that says, ‘You do not mess with elections this close to Election Day.’ And here we’ve already completed a primary, and the Missouri Supreme Court takes it upon themselves to try to change the maps,” he said.

Both the federal district court and the U.S. Supreme Court have set a Monday deadline for parties to submit their arguments. Onder declined to speculate on the outcome, but he expressed hope that at least one court will “do the right thing and correct this egregious wrong.”

As the clock ticks down to Election Day, Missourians—and the nation—will be watching to see whether courts or politicians ultimately decide the fate of the state’s congressional lines.
