Justice Kavanaugh blocks Missouri's GOP-drawn congressional map; federal judge then orders use of that map for November elections

Justice Brett Kavanaugh blocked Missouri's GOP-drawn congressional map, leading to a federal judge's order to use the contested map for the November elections. The Missouri Supreme Court previously ruled the map never legally took effect, citing a valid referendum petition against it.

Justice Brett Kavanaugh denied an emergency application from Missouri Secretary of State Denny Hoskins, blocking the GOP-drawn congressional map, known as House Bill 1 (HB 1). This decision followed a ruling from Chief U.S. District Judge Stephen Clark, who mandated the use of HB 1 for the upcoming November elections.10

Clark's ruling came after the Missouri Supreme Court determined that the map had never legally taken effect due to a valid referendum petition with over 300,000 signatures submitted by opponents. The court stated that the map was not law and ordered the use of Missouri's 2022 congressional map unless voters approved the new districts in November.8

In his ruling, Clark emphasized that switching maps mid-election could nullify primary ballots and create unequal voter classes, stating, “Using a different map for the general election would wreak havoc on the fairness and orderliness of Missouri’s congressional elections.” Missouri Attorney General Catherine Hanaway expressed the state's commitment to comply with the ruling, arguing that changing maps between elections is “simply not feasible and profoundly unjust to Missouri voters.”5

The Supreme Court's decision is a significant setback for the GOP, which aimed to leverage the new map to gain an advantage in the upcoming elections. Gov. Mike Kehoe called the ruling “much-needed clarity” for voters and officials, emphasizing the importance of consistency in election rules.6

The case highlights ongoing tensions surrounding redistricting in Missouri, particularly as the state navigates the implications of a politically charged map drawn under pressure from former President Trump.
