Missouri’s congressional redistricting battle may look settled after the Missouri Supreme Court upheld the state’s new congressional map last week.
But for voters in Kansas City — where the new map splits the city into three congressional districts — the legal and political fight is far from over.
In fact, election officials across Missouri are still struggling to determine exactly which district lines should govern the Aug. 4 primary election, while a separate lawsuit now accuses state officials of intentionally delaying decisions long enough for elections to move forward under the disputed map.
At the center of the fight are two overlapping questions:
First, is the new congressional map constitutional?
Second, even if it is constitutional, do Missouri voters still have the right to stop it through the state’s referendum process?
The answers have become tangled in a series of lawsuits, court rulings and procedural delays that even some election officials say are difficult to fully untangle.
How Missouri Got Here
The fight began after Missouri Republicans approved a new congressional map during a 2025 special session aimed at strengthening GOP power in Congress.
The new map splits Kansas City among three congressional districts instead of largely keeping the city together in one district. Critics argue the changes weaken Kansas City’s political influence and dilute Black and urban voting strength.
Opponents challenged the map in court while a coalition called People Not Politicians launched a referendum petition drive seeking to place the issue before Missouri voters. The group submitted more than 300,000 signatures in December.
The Missouri Supreme Court Upheld the Map
Last week, the Missouri Supreme Court ruled the congressional map itself could remain in place.
The court rejected arguments that the map violated constitutional standards for compactness and contiguous districts. The court also said challengers failed to prove the districts clearly violated the Missouri Constitution.
In its ruling, the court emphasized that congressional map drawing is largely a political decision left to lawmakers rather than judges.
That ruling was viewed as a major victory for Missouri Republicans.
But it did not settle the separate referendum fight.
Why the Referendum Fight Is Still Active
The major unresolved issue now is whether Missouri Secretary of State Denny Hoskins will certify the referendum petition for the November ballot.
Under Missouri law, Hoskins has until primary election day to officially decide whether the petition has enough valid signatures and whether the referendum is legally allowed.
Hoskins has publicly indicated he intends to use most or all of the time available to make that decision.
That timing has created enormous uncertainty for election officials.
Under Missouri’s Constitution, referendum petitions are supposed to suspend laws from taking effect until voters decide the issue.
But in last week’s ruling, the Missouri Supreme Court said that suspension does not officially occur until the secretary of state certifies the petition.
At the same time, however, the court also said that if the petition is eventually certified, the suspension could apply retroactively back to Dec. 9, the date the signatures were originally submitted.
That legal distinction has become the center of the current controversy.
Why Election Officials Are Concerned
The possibility of retroactive suspension means Missouri could conduct the August primary election under the new congressional districts only to later face legal arguments that the districts should never have been used in the first place.
County clerks and election officials say that uncertainty makes it difficult to prepare ballots, assign voters to districts and finalize precinct maps.
Kansas City election officials have said the new map affects more than 100,000 voters and requires extensive precinct-by-precinct review because some district lines split existing precincts and neighborhoods.
Boone County Clerk Brianna Lennon publicly announced she would not update voter rolls until Hoskins officially decides the referendum question, arguing the court ruling left the legal status of the districts uncertain.
Other local election officials have also expressed frustration over what they describe as limited guidance from the secretary of state’s office.
Why Critics Believe the Delay Matters
Opponents of the map argue Hoskins’ decision to delay his ruling to the last possible day — primary day — allows Missouri Republicans to move the election process forward under the new map before courts can fully resolve whether the referendum should have suspended the law months ago.
The strategy, critics argue, may be less about ultimately winning every legal argument and more about pushing the election process so far forward that courts become reluctant to disrupt it.
Once candidates have filed, ballots are printed, absentee voting begins and primary elections are completed, courts historically become much more cautious about ordering major election changes because of the confusion and disruption it could create for voters and local election systems.
That is one reason opponents accuse Hoskins and Missouri Attorney General Catherine Hanaway of intentionally slowing the process.
A new lawsuit filed this week by People Not Politicians accuses both officials of acting in bad faith by delaying certification and pressuring local election officials to move ahead using the new districts.
Republicans, meanwhile, argue the new map is currently lawful, the Missouri Supreme Court has already upheld it and Hoskins is simply operating within the timeline provided under state law.
What Happens Next
At this point, the congressional map remains legally in effect because the referendum petition has not yet been certified.
But the legal fight over the referendum itself is continuing.
The new lawsuit asks a judge to force Hoskins to make a certification decision before the Aug. 4 primary election.
No timeline has been announced for when a judge may rule on that request.
However, because the case directly affects Missouri’s election calendar, pressure is growing for courts to act quickly as local officials approach deadlines for ballot preparation and voter assignment changes.
For now, Missouri voters — especially those in Kansas City — remain caught in a legal and political battle that could continue right up to the primary election itself.

A Larger Fight Over Missouri’s Petition Initiative System
Critics say the fight back and delay by Hoskins is part of the assembly’s fight to limit Missouri citizen’s ability to change policy through the state’s petition initiative process.
After voters approved measures lawmakers opposed — including abortion rights, Medicaid expansion and marijuana legalization — Missouri Republicans advanced a constitutional amendment that will appear on the November ballot seeking to make citizen-led initiative petitions harder to pass.
In response, voting-rights advocates recently submitted their own initiative petition seeking to prevent lawmakers from weakening Missouri’s existing petition initiative system and limiting voters’ ability to directly shape state law.
Opponents of the congressional map argue Hoskins’ handling of the referendum challenge fits into that broader effort by Republican lawmakers to reduce the power of voters to directly challenge legislative decisions they disagree with.
