Missouri Redistricting Returns to Supreme Court as Appeals Court Orders GOP Map

Missouri's congressional redistricting case has returned to the U.S. Supreme Court for the third time in three weeks after the 8th Circuit Court of Appeals ordered the state to use a Republican-drawn 2025 map for November's election, despite prior Supreme Court interventions favoring the 2022 map. The appeals court decision, placed on hold until September 28, conflicts with state law validated by Missouri's Supreme Court and creates a clash over whether federal courts can override state court determinations in state-law redistricting disputes.

Missouri's congressional redistricting dispute has escalated to the U.S. Supreme Court for the third time in three weeks, following a surprising reversal by a federal appeals court. On Monday, September 21, the 8th U.S. Circuit Court of Appeals ruled that Missouri must use the 2025 congressional map—drawn by Republicans and intended to secure an additional GOP House seat—in the November election. The three-judge panel concluded that using the 2022 map for the general election, after conducting the August primary under the 2025 map, would violate equal protection rights by giving some voters disproportionate influence.

The appeals court decision directly contradicts two prior U.S. Supreme Court interventions. The Supreme Court had previously declined to overturn a Missouri Supreme Court ruling that invalidated the 2025 map under state law, citing a successful referendum petition that suspended its legal effect. Election officials had already begun mailing ballots using the 2022 map to overseas voters and were starting absentee voting when the 8th Circuit issued its order. To provide time for opponents to seek emergency relief, the appeals court stayed its decision until September 28, meaning the 2022 map remains in use pending Supreme Court action.

On Tuesday evening, September 23, opponents led by People Not Politicians filed an emergency appeal to the Supreme Court, arguing that requiring a map change mid-election creates chaos and disenfranchises voters. Justice Brett Kavanaugh ordered Missouri officials and Republican plaintiffs, including U.S. Rep. Bob Onder, to respond by Wednesday afternoon. State officials argued that opponents lack legal standing to challenge the map and contended that using the 2025 map would provide voters stability by maintaining the districts used in the primary.

The case represents an unusual collision between state and federal authority. Missouri's Supreme Court had ruled 7–0 that the referendum petition both mandated a November ballot measure on the map and immediately suspended its legal effect—meaning it never legally took effect for the 2025 elections. The 8th Circuit, however, asserted federal oversight on grounds that federal election law requires consistency between primary and general election districts. Legal experts noted the ruling expands judicial power under the Elections Clause beyond what the Supreme Court has previously endorsed.

The dispute centers on competing claims about voter confusion and legal authority. Republican officials warned that switching maps for a fifth time in September would disenfranchise 1.4 million primary voters and create administrative chaos. Opponents countered that ballots have already been printed and mailed using the 2022 map, making mid-election changes impossible to execute without further disruption. The 2025 map was drawn to make Democratic Rep. Emanuel Cleaver's Kansas City-based 5th District substantially more competitive for Republicans.

Why This Matters

Three competing maps and two levels of courts create immediate operational stakes: overseas ballots and absentee voting have already begun using the 2022 map; a forced switch to the 2025 map by September 28 would require reprinting and remailing 1.4 million ballots mid-election. The dispute tests whether federal law (Elections Clause consistency) overrides state law (referendum suspension) in redistricting, with direct impact on which districts will be contested in November and the legal authority to make that determination. All Supreme Court action is emergency-based with no scheduled resolution date.
