The lawsuit, filed by a coalition of voting rights organizations, Democratic Party activists, and minority voters across Missouri, argued that the redistricting plan violated multiple provisions of the Missouri state constitution, including clauses requiring fair representation and equal voting power for all residents. Plaintiffs presented extensive evidence showing that the map was intentionally gerrymandered to give Republican candidates an unfair advantage in 6 of Missouri’s 8 congressional districts, splitting densely populated, left-leaning urban communities in St. Louis and Kansas City across multiple districts to dilute the voting power of Democratic and minority voters. They noted that the map was designed to lock in a 6-2 Republican majority in the state’s U.S. House delegation, even though Democratic candidates regularly win roughly 40% of the statewide vote in major elections. In the majority opinion, the court’s conservative majority ruled that plaintiffs failed to meet the legal threshold to overturn the redistricting law, noting that the Missouri state constitution does not explicitly bar partisan gerrymandering, and that the state legislature has broad authority to draw district boundaries as part of its statutory duties. The two liberal justices on the court issued a scathing dissenting opinion, arguing that the ruling effectively gives state lawmakers unlimited leeway to engage in extreme partisan manipulation of electoral maps, at the expense of fair representation for Missouri voters who do not support the ruling party. The ruling removes the last legal barrier to using the contested map for the 2024 U.S. House elections, which are scheduled for November. Advocacy groups that backed the lawsuit have stated that while they are disappointed with the ruling, they will continue to push for state constitutional reforms to ban partisan gerrymandering in future redistricting cycles. Republican leaders in the Missouri General Assembly praised the ruling as a victory for the rule of law, noting that the map was drafted and passed through the standard legislative process with broad support from elected representatives of Missouri voters.
