Supreme Court to Decide Missouri's Contested Redistricting Maps
The Supreme Court agreed to hear Missouri's redistricting dispute amid conflicting court rulings.
Why it matters: Redistricting shapes electoral outcomes and sets legal precedents that impact how political maps are drawn nationwide, a critical issue for election law attorneys and government counsel.
- Missouri General Assembly passed House Bill 1 in September 2025, redrawing maps to favor Republicans, potentially winning seven of eight seats.
- Opponents collected 300,000+ signatures to put a referendum on the November 2026 ballot, challenging the new maps.
- Missouri Supreme Court ruled the new districts never became law, ordering the old map back and the referendum placed on the ballot.
- A federal judge allowed use of the new map, creating conflicting court orders and legal confusion before primaries.
- Justice Brett Kavanaugh denied an emergency GOP appeal allowing the new maps, rejecting it without explanation.
- Missouri AG Catherine Hanaway warned that no court has overturned redistricting between primaries and generals, flagging risk of election chaos.
In September 2025, Missouri's legislature passed House Bill 1 (HB 1), redrawing congressional districts to favor Republicans, likely shifting the state's map from 6-2 to 7-1 GOP advantage. Opponents swiftly mobilized, collecting over 300,000 signatures to challenge HB 1 and place a referendum on the November 2026 ballot, as reported by The Washington Post.
Missouri Secretary of State Denny Hoskins delayed acknowledging the referendum, enabling the new districts to be used in the August 2026 primaries. However, the Missouri Supreme Court declared that the new maps never became law and reinstated the previous districts, ordering the referendum on the ballot. Contradicting this, a federal judge allowed the new maps for upcoming elections, causing legal uncertainty.
Justice Brett Kavanaugh, in an emergency appeal by the GOP, denied efforts to implement the new maps without explanation, as noted by The Daily Beast. Missouri Attorney General Catherine Hanaway highlighted the unprecedented nature of courts overriding redistricting between primary and general elections, emphasizing the risks of electoral chaos—calling it a "constitutional crisis" (AP News).
With absentee ballot deadlines approaching, the conflicting court rulings produce uncertainty for voters and candidates alike. As Associated Press reporter David A. Lieb observes, "The situation remains unresolved as the Supreme Court considers the latest appeals." This case’s outcome will have far-reaching impacts on election law and redistricting norms nationwide.
By the numbers:
- 300,000+ signatures collected for referendum petition — efforts to challenge HB 1
- 7 of 8 congressional seats projected to favor Republicans under new map — potential GOP advantage
- August 2026 primaries — scheduled use of contested new districts
Yes, but: The Supreme Court has yet to rule, leaving unresolved whether the new maps will be used in upcoming elections amid the legal conflict.
What's next: The Supreme Court's forthcoming decision will determine which congressional maps govern Missouri's 2026 midterm elections.
