The Missouri Supreme Court on Tuesday upheld a Republican-backed congressional map that could reshape the state’s political landscape ahead of the 2026 midterms, delivering a key legal victory for GOP lawmakers while leaving several challenges unresolved.
In a closely divided 4–3 decision, the court rejected arguments that the Missouri Constitution limits redistricting to once per decade following the U.S. census. Instead, the majority held that while the constitution requires lawmakers to redraw districts after each census, it does not prohibit them from doing so more frequently.
“The obligation to legislate congressional districts once a decade does not limit the General Assembly’s power to redistrict more frequently than once a decade,” the court wrote. “Simply put, ‘when’ does not mean ‘only when.’”
The ruling affirms a 2025 law, known as HB1, passed by Missouri’s Republican-controlled legislature and signed by the state’s GOP governor. The measure redraws congressional lines mid-decade in a way designed to give Republicans an advantage in at least one additional district.
Missouri lawmakers had previously adopted a 6–2 congressional map following the 2020 census, preserving two Democratic-held seats centered in St. Louis and Kansas City. But under the new map, the Kansas City-based 5th Congressional District—currently represented by Democratic Rep. Emanuel Cleaver—would be split, creating a more favorable landscape for Republicans and effectively shifting the delegation toward a 7–1 GOP advantage.

Republicans argue the move is both lawful and necessary to reflect political realities in the state, while critics characterize it as an aggressive partisan redraw aimed at securing additional seats in a narrowly divided U.S. House.
The court’s majority relied on longstanding precedent to support its interpretation, emphasizing that legislative powers are not limited unless explicitly restricted by the constitution. Citing prior case law, the opinion stated that “an express enumeration of legislative powers… cannot be considered as the exclusion of others not named unless accompanied by negative terms,” concluding that mid-decade redistricting is permissible because it is not “expressly restrained.”
The split decision reflected partisan divisions within the court. The four-justice majority consisted of Republican appointees, while the dissent included two Democratic appointees and one Republican appointee who broke with the majority.
The ruling marks a significant win for Republicans, including President Donald Trump, who had encouraged GOP-led states to revisit congressional maps ahead of the midterms as part of a broader national effort to counter Democratic advantages in other states.
Still, the legal battle over Missouri’s map is far from over.
Opponents are pursuing multiple avenues to block or alter the map before it can fully take effect. A separate lawsuit, backed by the Democratic-aligned National Redistricting Foundation, argues that the map violates the state constitution’s requirement that districts be geographically compact. That case is also expected to reach the Missouri Supreme Court.
In addition, a coalition of Missouri Democrats is seeking to force a statewide referendum on the new map, which could delay or overturn its implementation. Advocacy groups say they have gathered sufficient signatures to qualify the measure for the ballot, though certification by state officials remains pending.
Another legal challenge, brought by civil rights groups including the NAACP, has already been appealed to the state’s high court after being dismissed at the trial level, adding further uncertainty.
The timing of these challenges could prove decisive. Candidate filing for Missouri’s 2026 congressional primaries opened in late February and is set to close at the end of March, with the primary election scheduled for August 4. If courts or election officials act before those deadlines, the map could still be altered or frozen; if not, the new lines are likely to govern the upcoming election cycle.
For now, however, the court’s ruling leaves the GOP-drawn map in place, positioning Republicans to compete for an additional House seat in a state that has trended increasingly red in recent years.
