Supreme Court Just Handed Republicans a Rare and Massive Defeat Over a Disputed Congressional Map

The U.S. Supreme Court has denied Missouri's request to use a newly drawn congressional map for the November midterm elections, handing Republicans a major setback in their effort to reshape a competitive House district — but a federal judge issued a conflicting order minutes later, leaving the state's election map in legal uncertainty.

Justice Brett Kavanaugh, who handles emergency matters arising from Missouri, denied the state's application on Tuesday, 8 September, without referring it to the full Supreme Court or explaining his decision. The move left in place a Missouri Supreme Court ruling that blocks use of the Republican-backed map unless voters approve it in a November referendum.

The situation changed almost immediately when Chief U.S. District Judge Stephen R. Clark issued a temporary restraining order requiring Missouri to use the newer map for the 3 November general election. The competing orders have placed the state's congressional elections at the centre of an unresolved legal fight.

Kavanaugh Rejects Missouri's Emergency Bid

Missouri Secretary of State Denny Hoskins had asked the Supreme Court to stay the Missouri Supreme Court's 3 September ruling. The application was supported by the Republican National Committee, the National Republican Congressional Committee and the Missouri Republican State Committee.

Kavanaugh denied the emergency application without comment. The Supreme Court docket shows that the application was filed on 4 September and that responses were submitted before Kavanaugh issued his decision four days later.

The Missouri Supreme Court had ruled unanimously that a citizen-led referendum petition challenging House Bill 1, the 2025 redistricting law, was legally sufficient. It ordered Hoskins to place the referendum on the November ballot and barred officials from using the new congressional districts unless and until voters approve them.

GOP Map Puts Cleaver's Seat in Play

The Republican-drawn map would make Missouri's congressional delegation more favourable to the GOP. It substantially reshaped the Kansas City-based 5th Congressional District, currently represented by longtime Democratic Representative Emanuel Cleaver.

The new boundaries were expected to give Republicans a stronger chance of capturing Cleaver's seat as part of a broader mid-decade redistricting campaign backed by President Donald Trump. Republicans hold a narrow majority in the House, making individual competitive districts potentially significant to control of Congress.

The new districts were also used during Missouri's August primary elections. State officials argued that reverting to the previous map after candidates had already been nominated would create serious disruption and confusion for voters and candidates.

Federal Judge Orders GOP Map Back Into Use

Clark's ruling came in a separate federal lawsuit brought by Republican Representative Bob Onder and other plaintiffs. The federal judge temporarily barred Missouri officials from using any congressional map other than the HB 1 map for the November election.

The order temporarily requires Missouri officials to use the Republican-backed districts despite the Missouri Supreme Court's ruling under state law. It is set to remain in effect for 14 days while the federal case moves forward.

The federal court's action does not erase the Missouri Supreme Court's ruling. Instead, the two orders create a direct conflict over which map state election officials must use, with the federal case now moving through the appeals process.

Opponents of the federal order have appealed to the U.S. Court of Appeals for the Eighth Circuit. The dispute could also return to the Supreme Court if the appeals process does not resolve the issue before election deadlines.

Missouri Election Now Faces Legal Uncertainty

Missouri Attorney General Catherine Hanaway said the state was prepared to comply with Clark's order and use the 2025 map for the November election. The state had previously argued that changing congressional boundaries after the primary would undermine the orderly administration of the election.

For now, the legal status of Missouri's congressional districts remains unsettled. The Missouri Supreme Court has held that the 2022 map remains in force for the November election, with the new map unable to take effect unless voters approve HB 1, while the federal court has temporarily ordered officials to use the 2025 map.

The referendum is scheduled for the November ballot. Until the federal appeal and any further Supreme Court action are resolved, Missouri's congressional candidates and voters face continued uncertainty over which districts will govern the November election.
