Missouri election map remains caught between court orders

Missouri election officials remain caught between competing court orders over the congressional map for the November 3, 2026, general election. The Missouri Supreme Court barred use of the Republican-backed House Bill 1 map under state law, while a federal judge ordered officials to keep using that same map after the August 4 primary.

The conflict intensified on September 8, when Justice Brett Kavanaugh denied Missouri Secretary of State Denny Hoskins’ emergency request to pause the state-court ruling. The same day, the U.S. District Court for the Eastern District of Missouri issued a temporary restraining order barring Hoskins and state officials from using any congressional map other than House Bill 1.

The Eighth U.S. Circuit Court of Appeals then denied a stay pending appeal on September 9, saying it either lacked jurisdiction over the interlocutory appeal or, based on the briefing available, that the stay factors had not been met. The underlying legal dispute remains unresolved.

The immediate question is operational: which map must Missouri use as election officials prepare ballots, assign districts and conduct the general election?

Why the Missouri Supreme Court blocked House Bill 1

The Missouri General Assembly passed House Bill 1 on September 12, 2025, replacing the congressional map enacted in 2022. Missouri used the House Bill 1 districts for its August 4, 2026, primary election.

On September 3, the Missouri Supreme Court ruled that the Missouri Constitution allows voters to use a referendum to challenge a congressional map adopted by the General Assembly. The court treated the referendum petition as suspending House Bill 1 under Missouri law and barred Hoskins from using the map for the November general election.

The state court said House Bill 1 was “not the law and has never been the law” under its interpretation of state law. Its ruling addressed whether Missouri’s referendum process applies to congressional redistricting. The court did not decide the separate federal claims involving the Elections Clause, Article I, Section 2, or equal protection.

Why the federal judge ordered the map to remain

The federal case focused on what would happen if Missouri switched maps after voters and candidates had already participated in the primary under House Bill 1.

In the September 8 temporary restraining order, the federal judge said some voters would be assigned to different congressional districts under the older 2022 map. Candidates who won nominations under House Bill 1 also could find themselves campaigning in districts with different boundaries or electorates.

The judge concluded that changing maps after the primary could disenfranchise voters whose ballots were cast under the House Bill 1 districts and undermine congressional nominations. The order also noted that Missouri’s deadline for finalizing the November ballot was 5 p.m. on September 8.

The order was temporary, not a final ruling on the merits. It directed state officials not to implement, use, publish, distribute or mandate any congressional map other than House Bill 1 for the November election. The federal judge’s reasoning relied on federal constitutional claims, including the argument that changing maps after the primary could violate protections for voters and candidates.

What the Supreme Court and Eighth Circuit actions mean

Hoskins asked the U.S. Supreme Court for emergency relief from the Missouri Supreme Court’s September 3 ruling. The Supreme Court docket shows that Justice Kavanaugh denied the application on September 8.

That denial left the Missouri Supreme Court’s state-court ruling in place. It did not decide the underlying federal constitutional questions, and it did not eliminate the separate federal district court order directing officials not to use a map other than House Bill 1.

The Eighth Circuit’s September 9 order also did not resolve the merits. The appellate court denied a stay pending appeal and a request for summary reversal, while denying an administrative stay as moot. It said the court either lacked jurisdiction over the appeal or that the stay factors had not been satisfied based on the briefing then before it.

Those actions leave Missouri with competing directives addressing different legal issues: the Missouri Supreme Court’s state-law injunction against House Bill 1 and the federal court’s temporary order preserving the map used in the primary.

Why Hoskins faces a show-cause proceeding

After the federal order, the Missouri Supreme Court issued a September 8 order requiring Hoskins to show cause why he should not be held in contempt for violating its September 3 injunction.

The court specifically asked Hoskins to address his September 8 instruction to local officials to use House Bill 1 and to explain how its injunction remained in force after Justice Kavanaugh denied his emergency application. The court set a response deadline of noon on September 9 and scheduled oral argument for September 10, requiring Hoskins to appear in person.

The show-cause order was not a finding that Hoskins was already in contempt. In his response, filed September 9, Hoskins argued that the federal order required him to proceed with House Bill 1 and that he could face federal contempt exposure if he disregarded it. He also asked the federal court to enjoin the Missouri Supreme Court from holding him in contempt for following the federal order.

What Missouri voters and candidates should watch

Voters should expect uncertainty about congressional district boundaries until additional appellate action or a merits ruling clarifies which directive controls. The dispute does not necessarily mean every voter would move to a different district, but the federal court identified potential changes affecting some voters and candidates.

The uncertainty could affect district assignments, candidate jurisdictions, campaign operations, ballot preparation and instructions sent to local election authorities. The situation is especially urgent because the August 4 primary has already occurred and the statutory deadline for finalizing the November ballot passed on September 8.

The next important developments include proceedings on the Missouri Supreme Court’s show-cause order, continued litigation in federal court, possible further appeals and additional instructions to local election officials.

For now, the central issue is not whether House Bill 1 is permanently valid or permanently invalid. It is whether Missouri can change congressional districts after conducting its primary under that map without disrupting voters’ choices and the nominations already made.
