But it is unlikely to be the final word in the case, with Republican officials already pledging to appeal the ruling.Recommended Stories list of 3 itemslist 1 of 3Louisiana lawmakers pass congressional map favouring Republicanslist 2 of 3Inside the results: How redistricting shaped Tennessee’s primary electionlist 3 of 3US Arabs eye ‘historic’ Senate win for Abdul El-Sayed despite AIPAC attacksend of listAt the heart of the case is a congressional map signed into law in September 2025, designed to help Republicans win an extra seat in the US House of Representatives this year.But the partisan redistricting effort prompted a popular backlash, with nearly 300,000 Missouri residents signing a petition to instead put the new map to a vote.Missouri’s Secretary of State Denny Hoskins rejected the petition as legally insufficient. That set up the legal fight, which the Missouri-supreme-court" class="entity-link entity-organization" data-entity-id="199935" data-entity-type="organization">Missouri Supreme Court decided on Thursday.“The referendum petition was legal, sufficient, and timely, and the secretary incorrectly concluded otherwise,” the court wrote in its ruling.It added that the Missouri Constitution has made such petitions legal, and “no exception applies”. The court is staffed by seven judges, five of whom are Republican-appointed.The decision, however, places Missouri in a complicated position. Two months remain until the midterm elections, and ballots will soon be printed.There are also outstanding legal questions over whether a state’s general election can use different congressional districts than its primaries did.Missouri Attorney General Catherine Hanaway, a Republican, said she would immediately appeal the ruling to the US Supreme Court. She called Thursday’s decision a “full-fledged constitutional crisis”.“Never before in American history has a court overturned a congressional map after a primary and before a general election,” she said in a statement.Trump also denounced the ruling in a social media post, calling it “horrible, ridiculous, and unConstitutional”.“The Missouri-supreme-court" class="entity-link entity-organization" data-entity-id="199935" data-entity-type="organization">Missouri Supreme Court just ridiculously ruled in favor of changing the maps back to what they were a long time ago. It’s called, Ancient History,” he wrote.Last year, Trump triggered the nationwide redistricting fight when he approached Texas state lawmakers to redraw their maps in a way that would give Republicans an advantage.Normally, congressional maps are redrawn once every 10 years to reflect census results.But Trump encouraged Republican-led states to issue new maps mid-decade, as a strategy to help the right-wing party maintain control over the House.Some 10 states ultimately decided to redistrict, including Missouri. Most tilted in favour of Republicans. California, meanwhile, redrew its map to skew Democratic.Prior to Thursday’s ruling, Missouri’s Supreme Court affirmed that the special legislative action to change the state’s congressional map was lawful. In the US, no federal law bars partisan redistricting, known as gerrymandering.But Thursday’s decision upheld the legality of the petition campaign to put the map up for a vote.The Missouri-supreme-court" class="entity-link entity-organization" data-entity-id="199935" data-entity-type="organization">Missouri Supreme Court barred the 2025 map from being used in November’s midterm election or any future election until Missouri voters approve it first.The group People Not Politicians spearheaded the referendum petition. In a statement on Thursday, it applauded the state court’s decision, which overturned a lower court ruling.“Supreme Court of Missouri has ruled: Missourians will vote on politicians’ rigged map,” the group wrote on social media.It also blamed Missouri’s secretary of state for any hurdles to restoring the old map.“Hoskins had the power to prevent all this confusion months ago — and he chose not to,” the group said.A day before the court’s ruling, hundreds of people rallied outside the state Supreme Court, chanting: “Let us vote!”Grant Christensen, a resident of Jefferson City and referendum supporter, said he had signed the petition.“Gerrymandering is the same as voter suppression,” Christensen said. “Cutting up districts in order to steer them to vote one way or the other is not fair.”Missouri’s 2025 congressional map had already shaped the state’s primary elections. Critics, however, point out that Hoskins did not reject the referendum until August 4, the day of the party primaries.The outcome of the legal battle is likely to be most pivotal for Missouri’s 5th congressional district, currently held by Democrat Emanuel Cleaver. His district, which encompasses parts of Kansas City, was reshaped to favour Republicans.
