The Supreme Court on Friday stayed a district court injunction and an appeals court mandate and order that would have required Missouri to use a 2025 redrawn congressional map in the upcoming midterm election. Under the ruling, Missouri must use its 2022 map.
The ruling ends the extraordinary year-long effort by the Missouri secretary of state to use a redrawn map that would favor Republicans–in violation of state law.
The case started last fall, when the Missouri legislature redrew its congressional map to net Republicans one seat from the state. Opponents filed a petition in December 2025 to put the new map to a referendum. Under state law, if the petition signatures were valid, the petition would halt the new map, unless and until Missouri voters approved it in an election.
The secretary of state took no action on the petition, however, and instead ran the state’s primary election using the new 2025 map. At the same time, he announced that the petition was invalid on the ground that redistricting is not subject to a referendum under state law.
The state supreme court unanimously disagreed. The state supreme court ruled that redistricting is, indeed, subject to a referendum under state law. Moreover, it held that the 2025 map was never valid under state law (because of the petition), and it ordered the secretary of state to use the 2022 map in the upcoming general election.
The secretary of state then asked the Supreme Court to stay the Missouri supreme court ruling, arguing that it violated the U.S. Constitution. (He claimed that using the 2025 map for the primary and the 2022 map for the general would violate equal protection and the method of election for members of the House.) Justice Kavanaugh denied the request.
Soon after, a federal district court in Missouri ruled for the secretary of state and ordered the state to use the 2025 map in the general election. The Supreme Court stayed that order.
Then the Eighth Circuit ordered the district court to enter a permanent injunction requiring the state to use the 2025 map.
The Supreme Court on Friday stayed that order. The Court understated it: “Given this Court’s two prior orders in this litigation, our conclusion that this was error should come as no surprise.”
