US Midterms 2026Background
Seven justices sit en banc on the Supreme Court of Missouri in Jefferson City, deciding appeals as the state's highest court.
Its September 2026 HB 1 ruling showed how that role can affect an election directly. the Court suspended Missouri's 2025 congressional map on 3 September and later held Secretary of State Denny Hoskins in civil contempt over a breach of that order, before purging the finding when he changed course.
The subsequent federal orders did not alter the Court's place in Missouri's judicial system. They made its constitutional role more visible: state election disputes can bring its rulings into conflict with federal courts and require higher-court resolution.
Its authority faces federal challenge
On 3 September, the Supreme Court of Missouri suspended HB 1, Missouri's 2025 congressional map, and sent it to a November referendum. That order placed the Court at the centre of the state's dispute over which map should govern the election.
A federal restraining order on 8 September directed Missouri to use HB 1 instead. On 21 September, the Eighth Circuit also ordered use of the 2025 map, although it paused its own order until 28 September. For Missouri's highest court, the dispute tests the practical reach of its election ruling when federal courts issue conflicting instructions.
