Anti-Gerrymandering Group Asks Supreme Court to Block Missouri Map

An anti-gerrymandering organization has filed an emergency application asking the U.S. Supreme Court to block Missouri from using its newly enacted congressional map in the November 2026 elections, according to Bloomberg News reporting from September 9, 2026. The group argues the map is drawn to favor Republican candidates and should not be in effect while litigation continues.
The application marks at least the second time the Supreme Court has been asked to intervene in the Missouri redistricting dispute, according to the same Bloomberg report. The Court's earlier posture on the case, and whether it granted or denied prior relief, was not specified in available public records as of publication. The Court's docket would contain the full procedural history.
Control of the U.S. House of Representatives is directly at stake. Missouri currently sends six Republicans and two Democrats to the House, according to the official congressional record. If the challenged map shifts district lines in ways that alter those proportions, the net effect on the House majority margin could be one or more seats, depending on competitive-race outcomes.
The phrase "favors Republicans," as used by the anti-gerrymandering group in its application, is a legal characterization, not an independently verified finding by this publication. Whether the map constitutes an unlawful gerrymander under applicable federal or state law is the central legal question before the Court. No federal court judgment on the merits of that claim was available in public records as of September 9, 2026.
Gerrymandering litigation frequently produces conflicting lower-court orders, and Missouri has been no exception. As previously reported by The Congressional Times in Missouri Congressional Map in Dispute After Conflicting Court Orders, state and federal courts issued rulings pulling in different directions on which map should govern, creating election-administration uncertainty for county clerks and candidates who must file or verify ballot positions under a specific district configuration.
The Supreme Court has addressed redistricting emergencies on compressed timelines before. In Merrill v. Milligan (2022), the Court stayed a lower court order that had found Alabama's congressional map likely violated the Voting Rights Act, allowing the challenged map to remain in use through the 2022 elections while the case was argued on the merits. The Court then ruled against Alabama in June 2023. That precedent illustrates that the Court can and does act on redistricting matters close to election dates, though the outcome in any individual case depends on the specific legal questions presented.
The Purcell principle, articulated by the Supreme Court in Purcell v. Gonzalez (2006), holds that courts should be cautious about altering election rules close to an election date because last-minute changes can confuse voters and create administrative burdens. Missouri election officials would be required to implement any Court order on whatever timeline the Court sets, regardless of proximity to the November election.
The anti-gerrymandering group's identity and the specific legal theories in its Supreme Court application were not detailed in available public records as of publication. The application itself, once filed, becomes a public Supreme Court document and would specify the organization's name, the lower-court record number, and the precise relief requested.
Missouri's congressional districts are among a small number of House races that nonpartisan forecasters and party campaign committees have identified as potentially competitive in 2026, which is why the map's configuration carries national implications for House control. The Cook Political Report and other public forecasting tools rate individual Missouri districts, and those ratings are publicly available.
Several facts remain unknown from current public records: which lower court most recently ruled on the Missouri map and what that ruling said, the full name of the organization that filed the Supreme Court application, the docket number of the emergency application, and the deadline by which the Court has been asked to respond. Those details would be contained in the Supreme Court's public electronic filing system, accessible through the Court's website.
