In a significant decision this past Monday, the US Court of Appeals for the Eighth Circuit ruled that Missouri is required to use its new congressional districting map, enacted in 2025, for the upcoming November elections. This decision reflects ongoing disputes in Missouri after the state legislature passed a controversial redistricting bill, House Bill 1, the previous September. This bill notably altered Missouri’s Fifth Congressional District, a historically Democratic stronghold since 2025, sparking accusations of unconstitutional gerrymandering from Democratic Representative Emanuel Cleaver. Meanwhile, former President Donald Trump praised the changes, describing the new map as a fairer adjustment.
The debate over the maps intensified as opponents quickly mobilized a referendum, successfully petitioning the Missouri Supreme Court to halt the new map’s implementation, mandating the use of older district lines from 2022. The political theater escalated when Supreme Court Justice Brett Kavanaugh refused Missouri’s request to implement the newly drawn map for upcoming elections. Interestingly, shortly after Kavanaugh’s rejection, a federal district judge temporarily allowed the use of the new map, creating a conflicting judicial situation.
The Eighth Circuit’s recent opinion clarified that altering district lines after an August primary set using the 2025 map would infringe upon constitutional mandates that dictate Congress members be elected “by the People” per Article 1, Section 2 of the Constitution. Citing key cases like United States v. Classic and Wesberry v. Sanders, the court highlighted that maintaining voting rights across both primary and general elections precludes mid-election cycle changes to district lines, as such changes could disenfranchise voters.
Moreover, the court underscored that federal supremacy necessitates Missouri to comply with federal constitutional standards, thus negating any state-oriented interpretations that might conflict. The rejection of arguments rooted in the Purcell principle, which typically advises against changing election rules close to an election, was grounded in the fact that the 2025 map had been operative for nearly the entire election cycle, essentially preserving the status quo. The court’s directive for a permanent injunction mandates using the 2025 map moving forward, albeit with a stay until September 28, allowing the Supreme Court to potentially provide further guidance.
