Kavanaugh Blocks Missouri Congressional Map for 2026 Election

• Justice Brett Kavanaugh blocked Missouri's new congressional map (HB 1) from being used in the November 2026 elections.
• The map, intended to give Republicans an additional U.S. House seat, was halted by Kavanaugh's denial of an emergency request from Missouri's top election official.
• Kavanaugh's order upholds a Missouri Supreme Court ruling that had already barred the new map's implementation.
• The decision means the 2022 congressional map will remain in effect for the 2026 election cycle.
• Opponents had gathered over 300,000 signatures for a referendum on the new map, but the petition was rejected by the Secretary of State on August 4, 2026.

Justice Brett Kavanaugh recently issued a directive preventing Missouri from implementing a new congressional map, known as HB 1, for the upcoming November elections.

Justice Brett Kavanaugh recently issued a directive preventing Missouri from implementing a new congressional map, known as HB 1, for the upcoming November elections. This decision effectively blocks the state's attempt to redraw its electoral districts in a manner that was anticipated to secure an additional seat for Republicans in the U.S. House of Representatives. The brief order, released on Tuesday afternoon, came from Justice Kavanaugh in his capacity overseeing emergency appeals originating from the 8th Circuit, which encompasses Missouri.

The ruling specifically denied a request from Missouri's highest-ranking election official, who had sought to pause a previous decision by the Missouri Supreme Court. That state supreme court ruling had explicitly prohibited the deployment of the new redistricting plan. While Kavanaugh's order was placed on the Supreme Court's interim docket, its immediate effect is to solidify the electoral landscape for the 2026 election cycle, ensuring the continued use of the congressional map originally adopted in 2022 following the 2020 census.

The congressional map at the center of this legal dispute, Missouri HB 1 redistricting, was part of a broader effort by several states to redraw their electoral boundaries ahead of the 2026 elections. This initiative was notably encouraged by former President Donald Trump. The specific design of HB 1 aimed to allocate seven of Missouri's eight U.S. House seats to Republican candidates, a significant shift from the existing distribution.

Opposition to this new map quickly materialized. In December 2025, opponents, including Richard von Glahn, a key plaintiff in the ongoing congressional redistricting litigation, gathered and submitted more than 300,000 signatures. These signatures were intended to support a petition to place a statewide referendum on the new maps on the ballot for the November 2026 elections. However, Missouri Secretary of State Denny Hoskins rejected this petition on August 4, 2026. This date was not only the final day for him to make such a determination but also coincided with the state's primary election.

The denial of the emergency request by Justice Kavanaugh underscores the finality of state-level redistricting decisions, particularly as election cycles draw near. The Kavanaugh 8th Circuit emergency order effectively upholds the Missouri Supreme Court redistricting decision, which had already barred the new map's implementation. This outcome means that the 2022 map will remain in effect for the 2026 Missouri election map challenge, providing clarity for voters and candidates.

This ruling highlights the critical role state supreme courts play in shaping electoral maps and the limited avenues for last-minute intervention at the federal level once a state's highest court has rendered a decision. For political entities and election officials, the denial of this emergency appeal reinforces the weight given to state judicial pronouncements in the complex landscape of congressional redistricting litigation.

This ruling underscores the finality of state-level redistricting decisions once emergency appeals are denied by the Supreme Court, particularly close to an election. Lawyers advising political entities or election officials should note the limited avenues for last-minute intervention and the critical weight given to state supreme court rulings in shaping electoral maps.
