A Cole County judge ruled Wednesday that Missouri voters cannot use the referendum process to challenge the state's newly drawn congressional map, dealing a blow to organizers who had gathered hundreds of thousands of signatures trying to put the fight before the public. Judge Daniel Green sided with Secretary of State Denny Hoskins and Republican-aligned groups, finding that the Missouri Constitution does not allow citizens to overturn a legislatively approved congressional map through a ballot measure.
The ruling capped a trial that had been postponed from Tuesday to Wednesday at 10 a.m., a delay that allowed attorney John Gore to travel from Washington, D.C. to attend, according to ABC 17 News. The group behind the challenge, People Not Politicians, had asked Green to overturn Hoskins' rejection of its referendum and place the measure on the November ballot. The Republican National Committee and two Republican political action committees had joined the lawsuit in support of Hoskins, while the state argued it was simply too late to change districts tied to the November election.
What The Referendum Would Have Done
Had the referendum been certified, the state would have been required to use the old 2022 congressional districts until voters could weigh in on House Bill 1, the law that established the new map. People Not Politicians attorney Chuck Hatfield argued that Missouri law allows a referendum on any act of the legislature, and that the constitution specifically authorizes a public vote on House Bill 1 as an act of the general assembly.
The state countered that state and federal law prohibit a referendum on a congressional map altogether. The Missouri Attorney General's Office told the court that roughly 3.3% of Missouri voters could temporarily repeal a duly enacted congressional map before a public vote, framing the referendum threshold as disproportionately small compared to the stakes. Louis Capozzi, arguing for the Republican-aligned groups, said changing districts after millions of Missourians already voted in the August primary using the 2025 map could be chaotic and confusing.
A Century-Old Precedent, Revisited
Missouri voters have vetoed a congressional map before. In 1922, they successfully used the state's referendum process to reject a legislatively enacted congressional map, a precedent cited by Democracy Docket as evidence that citizen referendum challenges to congressional maps have historical roots in the state. Green acknowledged that 1922 vote in his ruling but concluded that more specific constitutional provisions assigning redistricting authority to the general assembly took precedence over the broader referendum guarantee in Article III, Section 49 of the Missouri Constitution.
That section reserves to voters the power to approve or reject “any act of the general assembly” through referendum, listing specific exceptions that do not explicitly mention congressional redistricting. Capozzi warned during arguments that allowing the referendum to proceed could let the minority political party freeze a redistricting map after every round of Missouri redistricting, and argued the challenge could lead to broader attempts to overturn or freeze congressional districts down the line.
Signatures Were Never The Real Fight
The case reached Green's courtroom only after a bruising signature-gathering campaign. Organizers submitted 305,968 signatures in December, far surpassing the roughly 107,000 valid signatures required across six congressional districts, according to Ballotpedia. That total was inflated in part because Hoskins had rejected more than 90,000 signatures collected before his office approved the petition's sample title, warning organizers that early collection amounted to a misdemeanor election offense, as reported by KCUR.
By this month, the fight over paperwork had evaporated. In an August court filing, Hoskins conceded the petition contained sufficient valid signatures, narrowing the legal dispute entirely to whether the Missouri Constitution permits a referendum on congressional maps at all, per the Missouri Independent. Richard Von Glahn, executive director of People Not Politicians, has led the group's push to get the map before voters despite that stripped-down legal terrain.
The Map Itself, And What Comes Next
House Bill 1 reshaped Missouri's 5th Congressional District to stretch roughly 200 miles east through 14 counties along the Missouri River while carving Kansas City into three districts, an effort aimed at converting the state's delegation from a 6-2 to a 7-1 Republican majority, according to the St. Louis American. The map specifically sought to flip the 5th District, currently held by Democratic U.S. Rep. Emanuel Cleaver in Kansas City. The Trump administration had urged passage of the map, and Missouri's Republican supermajority in the general assembly approved it out of a special legislative session Cole County Judge Christopher Limbaugh had already ruled Governor Mike Kehoe lawfully convened, as Hoodline reported in February.
Missouri's mid-decade redistricting push was not an isolated move. The state joined Texas and North Carolina in 2025 as one of three states undertaking mid-decade congressional redistricting to expand Republican representation in the U.S. House ahead of the 2026 midterms, a strategy encouraged by national party leaders to protect a narrow GOP House majority, Democracy Docket notes. Missouri lawmakers had already cleared one legal hurdle in March, when the Missouri Supreme Court ruled 4-3 in Luther v. Hoskins that the state constitution does not prohibit mid-decade redistricting without a new census, according to Courthouse News.
Supreme Court Poised To Have Final Word
Green's ruling is unlikely to be the last word. Missouri Supreme Court Chief Justice Brent Powell issued an extraordinary letter asking Green to deliver a speedy trial and directing the case toward the state's highest court ahead of a firm September 8 deadline for finalizing items on the November ballot. Powell has said he expects the lawsuit to reach the Missouri Supreme Court, and People Not Politicians had sought exactly that outcome, pushing for a speedy trial and rapid appeals before the ballot deadline arrives.
For now, the ruling means the congressional map drawn under House Bill 1 stands as the district lines for November, with August primary voters having already selected their candidates using those same boundaries. Whether the Missouri Supreme Court agrees with Green's reading of Article III, Section 49 before the September 8 deadline will determine whether Missouri voters ever get a direct say on the map that reshaped Kansas City's congressional representation.
