A federal appeals court has revived Missouri's Republican-drawn congressional redistricting map, ruling that the plan can stand despite a U.S. Supreme Court decision that had cast doubt on its legality. The Eighth Circuit's move marks a sharp turn in a legal battle that has bounced between state courts, federal courts, and the nation's highest bench for the better part of three years.
The ruling hands Missouri Republicans a significant win heading into the next election cycle. It also raises fresh questions about how federal courts will apply the Supreme Court's recent voting rights precedents to redistricting fights across the country.
A three-judge panel of the U.S. Court of Appeals for the Eighth Circuit ruled that Missouri's 2022 congressional map, drawn by the Republican-controlled state legislature, does not violate Section 2 of the Voting Rights Act. The panel reversed a lower federal court that had found the map likely diluted Black voting power in the St. Louis area, as Just the News reported.
The map had split Black communities in and around St. Louis across two congressional districts, reducing the concentration of Black voters in what had been a majority-minority district. Challengers argued this amounted to racial vote dilution in violation of federal law.
The Eighth Circuit disagreed. The panel concluded that the plaintiffs had not met the legal threshold required to prove a Voting Rights Act violation, finding that the challengers failed to demonstrate that a compact majority-minority district could be drawn as an alternative.
The ruling is striking in part because the Supreme Court had previously intervened in the Missouri map dispute. In 2023, the high court blocked Missouri's redrawn congressional map from taking effect, signaling concern about the plan's legality under voting rights law.
That intervention came after the Supreme Court's landmark decision in Allen v. Milligan, the Alabama redistricting case in which the justices reaffirmed that Section 2 of the Voting Rights Act requires states to draw majority-minority districts where certain conditions are met. The Allen ruling surprised many observers because a conservative-majority court upheld a broad reading of voting rights protections.
Missouri's challengers relied heavily on Allen, arguing that the same legal framework should compel the state to maintain a majority-Black congressional district in the St. Louis region. The Eighth Circuit, however, read Allen more narrowly, concluding that Missouri's demographic and geographic circumstances did not trigger the same obligations.
Under the previous congressional map, Missouri's First Congressional District encompassed most of the city of St. Louis and heavily Black portions of St. Louis County. The district had elected Black representatives for decades, including the late William Lacy Clay Sr. and his son, William Lacy Clay Jr., followed by Cori Bush.
The 2022 Republican-drawn map shifted the district's boundaries. It pulled in more white suburban voters and pushed out portions of the Black community, reducing the district's Black voting-age population. Critics said the move was designed to weaken Black political power in the region. Defenders of the map argued the new lines reflected legitimate redistricting criteria, including population equality and geographic compactness.
The practical effect was contested. Supporters of the old map warned that diluting the Black vote would make it harder for Black-preferred candidates to win. Republicans countered that the district remained competitive for Black candidates and that the Voting Rights Act does not guarantee any racial group a particular electoral outcome.
Before the Eighth Circuit stepped in, a federal district court had ruled in favor of the plaintiffs. That lower court found that the challengers had satisfied the three preconditions set out in Thornburg v. Gingles, the 1986 Supreme Court case that established the test for vote dilution claims under Section 2.
The Gingles test requires plaintiffs to show three things: that the minority group is large enough and geographically compact enough to form a majority in a single district; that the minority group is politically cohesive; and that white bloc voting usually defeats the minority group's preferred candidates. The district court found all three conditions met.
The Eighth Circuit disagreed on the first prong. The appeals panel found that the plaintiffs' proposed alternative map did not demonstrate a sufficiently compact majority-minority district, undermining the entire claim. Without satisfying that threshold requirement, the court held, the case could not proceed.
The decision lands in the middle of a nationwide tug-of-war over redistricting and voting rights. Courts in multiple states have wrestled with how to apply Allen v. Milligan, and the results have been uneven. In some states, courts have ordered new majority-minority districts. In others, like Missouri, courts have found the legal standard unmet.
The Supreme Court's voting rights rulings have reshaped redistricting battles in Georgia and other states, but the Eighth Circuit's reading suggests that Allen's reach may be more limited than voting rights advocates hoped. Conservative legal scholars have argued that Allen did not create a blanket mandate for majority-minority districts and that each state's facts must be evaluated independently.
Missouri's case also fits into a pattern of state-level redistricting conflicts playing out in courtrooms across the country. In Maryland, for instance, courts have grappled with a redistricting amendment fight that has its own complex procedural history.
Missouri's redistricting saga has been one of the most convoluted in the country. The Republican-drawn map faced challenges in both state and federal court almost immediately after the legislature approved it.
In state court, the Missouri Supreme Court blocked an earlier version of the GOP map, finding procedural problems with how it was enacted. That ruling prompted a federal lawsuit from a Missouri House Republican who sought to overturn the state court's decision.
The federal challenge under the Voting Rights Act proceeded on a separate track. When the district court sided with challengers, the state appealed to the Eighth Circuit. The Supreme Court's earlier stay of the lower court's order kept the Republican map in place during the appeals process, and the Eighth Circuit has now made that outcome more permanent by reversing the lower court entirely.
The challengers could seek rehearing before the full Eighth Circuit or petition the Supreme Court to take the case again. Whether the high court would agree to hear it remains uncertain. The justices previously declined to rescue the GOP map at an earlier stage, but the procedural posture has changed now that a full appellate ruling exists.
For now, Missouri's Republican-drawn congressional map stands. The Eighth Circuit's ruling means the map will likely govern the next round of congressional elections unless a higher court intervenes or the legislature draws new lines.
Voting rights groups have signaled they intend to continue fighting. The NAACP and other organizations that backed the challenge have argued that the Eighth Circuit's interpretation of Allen v. Milligan is too restrictive and conflicts with how other circuits have applied the decision.
Missouri Attorney General Andrew Bailey's office defended the map throughout the litigation. The state argued that the legislature acted within its constitutional authority and that the map reflected race-neutral redistricting principles.
The case now sits at a crossroads familiar in redistricting law: a circuit split may be developing over how to apply Allen, and the Supreme Court may eventually need to clarify the boundaries of its own precedent.
When the highest court in the land tells states what voting rights law requires and a federal appeals court reads that guidance to permit the very map the justices previously froze, the legal system has a clarity problem. Missouri voters deserve to know the rules before the lines are drawn, not after the ballots are counted.
