The Missouri Supreme Court delivered a major boost to Gov. Mike Kehoe on Wednesday, rejecting a legal challenge that claimed he overstepped his authority by calling last year’s special legislative session. For now, that ruling keeps the Republican-crafted “Missouri First” congressional map in place, along with controversial changes to the state’s initiative-petition rules. It also locks Missouri’s political world into a tight timeline that could decide which district lines are on the ballot for the August 4 primary.
What the court said
During Wednesday’s arguments, the justices drilled into competing readings of the governor’s power to summon lawmakers on “extraordinary occasions.” Assistant Solicitor General Joseph Kiernan argued that the state constitution gives the governor broad leeway to call a special session any time the legislature is not in regular session, saying, “If the framers of our state constitution wanted to constrain the governor, they would have said so.” Coverage of the hearing was provided by local outlets, including the St. Louis Business Journal.
What the NAACP argued
The Missouri State Conference of the NAACP had urged the court to strike down Kehoe’s September 2025 special session as unconstitutional and toss out both the congressional map and the initiative-petition changes that came out of it. The plaintiffs contended that the session did not qualify as an “extraordinary occasion” and filed their challenge the same day lawmakers convened last fall, according to Missouri Independent. Had the court bought that argument, the 2025 law and ballot changes could have been wiped off the books.
Why the map matters
The “Missouri First” map reshapes U.S. House districts in ways critics say carve up Kansas City and make a currently Democratic seat far tougher to hold. Supporters argue the new lines fix contiguity problems and better reflect population changes, while opponents call the mid-decade redraw a partisan gerrymander aimed at locking in a longer-term Republican edge. As KCUR reported, the overhaul has already scrambled candidate lineups and left local election officials hustling to update voter rolls.
Referendum and the calendar
Opponents of the map turned in roughly 300,000 petition signatures on Dec. 9, 2025, seeking a referendum that could put the new lines on hold until voters weigh in, according to The Associated Press. Local election authorities have only a few weeks to verify signatures, and Secretary of State Denny Hoskins has until Aug. 4 to decide whether the petition meets the threshold, a call that could determine whether the August primary runs under the 2025 districts or the prior map, as Missouri Independent explains. Petition organizers have already asked the courts to speed things up and say they are ready to press on with more litigation if needed.
Legal implications
At the heart of the fight is Article IV, Section 9 of the Missouri Constitution, which lets the governor, “on extraordinary occasions,” convene the General Assembly and requires that any special-session proclamation “state specifically each matter” to be considered, according to the state’s constitution. A Cole County judge previously ruled that Kehoe stayed within those bounds, setting the stage for the Supreme Court review. The constitutional language is posted by the Missouri Revisor of Statutes, and the earlier circuit court ruling was reported by Missourinet. However the high court’s reading of “extraordinary” is applied in practice, it will shape how freely future governors can deploy special sessions in the middle of political tug-of-wars.
What happens next
With the Supreme Court clearing Kehoe’s move, the spotlight now shifts to signature checks and the referendum’s path to the November ballot. Petitioners insist they have more than enough valid signatures and are pushing for quick certification, while some county clerks say they will wait for an official decision before redrawing precinct maps, as KCUR reported. Expect more legal filings, potential appeals, and plenty of hard-nosed organizing as the fight drifts from the bench to the ballot box this summer and fall.
