More about it
The Supreme Court of Missouri ruled on September 3, 2026, that this referendum belongs on the ballot and that House Bill No. 1 has not taken effect, so the 2022 congressional districts are the ones used for the November 3, 2026 U.S. House races whatever the result of this vote.3 The court's order says that if voters approve House Bill No. 1, its map would take effect 30 days after the election.3 On September 8, 2026, U.S. Supreme Court Justice Kavanaugh denied the Secretary of State's request to put the Missouri ruling on hold.4 The Secretary of State had found the referendum petition insufficient on August 4, 2026, and the Supreme Court of Missouri's opinion says the ballot summary used for this question was set by the Missouri Court of Appeals in People Not Politicians v. Hoskins (2026).3
