Missouri Supreme Court Blocks New Congressional Map and Sends It to Voters
The Missouri Supreme Court ruled on September 3, 2026, that HB 1, the state's new congressional redistricting law, cannot take effect until voters approve it in a November referendum, meaning the 2022 district boundaries will govern the November 2026 election. The court set a September 8 deadline for the Secretary of State to certify the measure for the ballot, overriding the office's own August 25 calendar deadline. An unresolved practical problem remains: candidates who won August primaries under the new HB 1 lines must now run in November under the older 2022 boundaries.
