Appeals court weighs Missouri House map switch after Supreme Court leaves referendum intact

A federal appeals panel on September 17 considered whether Missouri can use a Republican-drawn congressional map backed by President Donald Trump in the November 3 midterm elections, despite state-court rulings and a U.S. Supreme Court order that left the state’s voter referendum process in place.¹

The immediate question before the 8th U.S. Circuit Court of Appeals is which map Missouri should use — and whether federal courts can alter the state’s congressional districts after Missouri’s top court said voters must be allowed to decide the map’s fate and election officials began preparing ballots under the older 2022 lines.¹²

Missouri is currently set to run the general election under the congressional map used in 2022 and 2024. That follows a Missouri Supreme Court decision blocking the 2025 map unless voters approve it, and the U.S. Supreme Court’s stay of a federal district court order that had favored the newer map.¹²

The stakes include control of a Kansas City-area House seat held by Democratic Rep. Emanuel Cleaver. The 2025 map would significantly reshape the 5th Congressional District, a change Republicans hoped would help them win seven of Missouri’s eight U.S. House seats instead of their current six.¹⁵

Ballot deadlines narrow the court’s options

Election timing dominated the September 17 hearing. Local election officials told the court they were already printing ballots based on the 2022 districts and faced deadlines to send ballots to military and overseas voters and make absentee ballots available to others.¹

Associated Press reported that local officials cited a Friday deadline under federal law for overseas and military absentee ballots and a following Tuesday deadline under state law for other absentee ballots.¹ Missouri-based coverage reported the referendum will appear as Proposition A. A “yes” vote would approve the 2025 map for use in 2028, while a “no” vote would leave the 2022 map in place.²

Republican candidates pressing the federal case argued there was still time to change course. Their attorney told the 8th Circuit that the ballot deadline was not necessarily a point of no return and suggested courts could modify the timing for military and overseas ballots.⁴

Opponents of the 2025 map argued that changing districts so close to the general election would disrupt election administration and undercut the referendum rights recognized by the Missouri Supreme Court.¹⁴

Litigation has moved through state and federal courts

Missouri lawmakers passed the 2025 congressional map as part of a broader mid-decade redistricting push encouraged by Trump and aimed at improving Republican chances in the U.S. House.¹³ Opponents gathered petition signatures to force a statewide vote on the map, but Republican Secretary of State Denny Hoskins initially rejected the petition, arguing Missouri’s referendum process could not be used for congressional redistricting.¹³

The Missouri Supreme Court rejected that position and said the map could not take effect unless voters approved it. A federal district judge later issued a conflicting order barring Missouri from using any map other than the 2025 plan, but the U.S. Supreme Court stayed that order while the federal appeal proceeds.¹²

At the 8th Circuit, Missouri Solicitor General Lou Capozzi urged the panel to rule that the U.S. Constitution prevents a referendum petition from suspending a congressional map enacted by lawmakers. The argument puts the case at the intersection of state referendum law and the federal Elections Clause, which gives state legislatures a role in setting congressional election rules subject to federal limits.¹⁴

Courthouse News Service reported that the case could return to the U.S. Supreme Court on an emergency basis. Judge James Loken indicated the appeals court would need to act quickly because election officials must know which map to administer.³

Kansas City district is the political prize

The political effect is concentrated in the Kansas City area. The 2025 map would break up or substantially alter Cleaver’s Democratic-held 5th District and fold parts of it into more Republican-friendly territory.⁵

Under the current posture, Cleaver’s seat remains on the 2022 lines for the November 3 election. If the 8th Circuit revives the 2025 map and the Supreme Court allows it to take effect, the Kansas City-area race could be fought on lines more favorable to Republicans.¹⁵

The dispute has also produced new lawsuits over voter injury and election administration. A proposed class action by Kansas City-area voters argues Hoskins delayed action on the referendum in a way that caused some voters to cast August primary ballots in districts different from the ones they will use in November.⁶ Democracy Docket reported a second lawsuit seeking damages for voters allegedly forced to vote under different maps in the primary and general election.⁷

Separately, AP reported that two losing Republican primary candidates and three members of the 5th District Republican committee filed a state lawsuit asking a Cole County judge to void the August primary for the 5th District and require party committees to nominate general-election candidates instead.¹

What the appeals court must decide

The 8th Circuit could side with Republican candidates and state officials seeking to revive the 2025 map, side with referendum supporters and leave the 2022 map in place for November, or issue a narrower procedural ruling that sends the case back to the district court.²³

Any ruling is likely to trigger another emergency appeal to the U.S. Supreme Court, given the court’s prior stay and the rapidly approaching election deadlines.¹³

For now, the practical question is whether a federal court can reorder Missouri’s midterm map after state courts placed the 2025 plan before voters as Proposition A and election officials moved ahead under the older lines.²
