The Missouri Supreme Court ruled on Friday that the state's Republican-drawn congressional district maps cannot be used in the upcoming November elections, forcing a redraw of district lines weeks before the midterm cycle. The decision represents a major legal setback for the state GOP and could affect the balance of Missouri's congressional delegation.

The court's ruling invalidates maps that Republicans had approved through the state legislature, finding them legally deficient ahead of the election. Election officials will now face a compressed timeline to implement new district boundaries before ballots are finalized and mail-in voting begins.

The ruling adds Missouri to a growing list of states where courts have intervened in redistricting disputes in the lead-up to the 2026 midterms. Nationally, control of the House of Representatives remains closely contested, making individual state-level redistricting decisions potentially consequential for which party holds the majority after November.

In a related development, a top Maryland court separately permitted a Democrat-backed redistricting measure to appear on the November ballot, underscoring that redistricting battles are playing out across party lines in multiple states simultaneously. Together, the rulings reflect continued judicial scrutiny of legislative map-drawing efforts ahead of the midterm elections.
