Justice Brett Kavanaugh on Tuesday blocked Missouri from using a new congressional map designed to give Republicans a seventh seat in the U.S. House, effectively reinstating the state’s 2022 district boundaries for the November 2026 elections. The brief order, issued from the Supreme Court’s emergency docket, denied a request from Missouri Secretary of State Denny Hoskins to pause a unanimous ruling by the Missouri Supreme Court that found the new map, known as HB 1, never legally took effect because a valid referendum petition had suspended it. This decision, which Kavanaugh issued without referring the matter to the full court, likely settles the map dispute for the 2026 election cycle and carries significant implications for the balance of power in the U.S. House and the interplay between state-level direct democracy and federal election law.<\/p>\n
The emergency application landed at the Supreme Court on<\/a> Friday night, Sept. 4, 2026, with Hoskins warning that a federal election administration disaster was unfolding in Missouri. He argued that the state was genuinely unsure whether it could switch its governing congressional map in time to run a timely federal election. Kavanaugh, who handles emergency appeals from the 8th Circuit, which includes Missouri, rejected that plea on Tuesday afternoon. The order itself was brief and contained no explication of the justice’s reasoning, but its practical effect was decisive: the map adopted in 2022, which currently gives Republicans six of the state’s eight House seats, will remain in place for the November 2026 general election.<\/p>\n By denying the stay, Kavanaugh declined to override the Missouri Supreme Court’s interpretation of its own state constitution. The order did not address the merits of Hoskins federal constitutional arguments, nor did it signal whether the full Court would eventually take up the case on appeal. For now, the emergency ruling restores the legal status quo that existed before the passage of HB 1, a map that was enacted with the encouragement of President Donald Trump and was designed to deliver seven of the state’s eight House seats to Republicans.<\/p>\n Missouri was one of several states that redrew its congressional maps ahead of the 2026 elections during a mid-decade redistricting push aligned with Trumps political strategy. The new map, HB 1, was passed by the Republican-controlled General Assembly and signed into law with the clear objective of flipping one Democratic-held seat to Republican control. Under the 2022 map, which was drawn after the 2020 census, Republicans held six seats and Democrats held two. HB 1 aimed to shift the balance to seven Republican seats and one Democratic seat, a change that could have national implications in a narrowly divided U.S. House.<\/p>\n Opponents of the new map, led by plaintiff Richard von Glahn, moved swiftly to challenge HB 1 through a mechanism deeply embedded in Missouris political tradition: the citizen-initiated referendum. In December 2025, von Glahn and his allies submitted more than 300,000 signatures in support of a petition to place a statewide referendum on the new map on the November 2026 ballot. Missouri law allows voters to suspend legislation by collecting enough signatures, forcing a popular vote before the law can take effect.<\/p>\n Secretary of State Hoskins, a Republican, rejected the petition on Aug. 4, 2026, the last day on which he could legally make that determination. The date was also the day of Missouris primary election, a timing choice that critics argued was deliberately obstructive. Hoskins based his rejection on a narrow reading of the Missouri constitution, asserting that it does not authorize a referendum on congressional redistricting plans passed by the General Assembly. In his view, the redistricting power belonged exclusively to the legislature, and the voters could not suspend or overturn such a map through the referendum process.<\/p>\n Within hours of Hoskins decision, von Glahn filed a lawsuit in state court seeking to reverse the rejection and bar the state from using HB 1. The case moved quickly through Missouris judicial system, culminating in a unanimous ruling by the Missouri Supreme Court on Sept. 3, 2026. The state high court held that the plain language of the Missouri Constitution authorizes a referendum as to any act of the general assembly and no exception applies for redistricting legislation. Because the referendum petition was legal, sufficient, and timely, the court concluded that HB 1 was never in effect and will not go into effect unless and until approved by the voters at the November 2026 general election.<\/p>\n The Missouri Supreme Court ruled on purely state-law grounds. The court held that the plain language of the Missouri Constitution authorizes a referendum on any act of the general assembly, and that no exception exists for congressional redistricting legislation. Because the referendum petition met all legal requirements under state law, the court concluded that HB 1 never took effect and will remain suspended until voters approve it at the ballot box.<\/p>\n The state supreme court also dismissed Hoskins argument that rejecting the new map would cause confusion, expense, and practical difficulties. The court noted that these arguments were particularly misplaced given the secretarys own delay in processing the petition, which created the very problems about which he was now complaining. In essence, the court held that any administrative chaos was of Hoskins own making.<\/p>\n After losing at the state level, Hoskins turned to the U.S. Supreme Court, raising several federal constitutional claims. His primary argument centered on the elections clause of the U.S. Constitution, which provides that the times, places, and manner of holding elections for senators and representatives shall be prescribed in each state by the legislature thereof. Hoskins contended that this clause vests the redistricting power exclusively in the state legislature, not in the voters through the referendum process. He argued that the Supreme Court has never held that just 3.3 percent of a states voters can unilaterally suspend a disfavored congressional map by submitting a referendum petition.<\/p>\n This argument invokes a long-running debate about the scope of the elections clause. Proponents of the independent state legislature theory, a doctrine that gained prominence in recent Supreme Court cases, argue that the clause places certain election-related powers beyond the reach of state constitutions and voter initiatives. Hoskins position essentially asked the Supreme Court to<\/a> extend that logic to the redistricting context, holding that a state referendum cannot suspend or nullify a congressional map adopted by the legislature.<\/p>\nThe Missouri Redistricting Dispute: From HB 1 to the Referendum<\/h2>\n
