On Monday, August 24, 2026, the U.S. Supreme Court issued a preliminary ruling in favor of the Donald Trump administration, overturning an injunction on key provisions of his executive order restricting mail-in voting ahead of the November midterm elections. The decision, reached by a conservative majority in a 6-to-3 ideological split, exposed a deep divide in the judiciary over the authority of states to control their own elections.
The dispute concerns provisions of the executive order signed by Trump on March 31, 2026, which require the creation of a federal list of U.S. citizens eligible to vote and direct the U.S. Postal Service to send ballots only to those included on it. The administration positions the measure as a way to combat unauthorized voting; critics call it an attempt at centralized federal control over elections historically managed by states.
The Court overturned an injunction imposed in June by federal judge Indira Talwani based on a court in Massachusetts. That injunction prevented implementation of the order in California and 22 other states, as well as the District of Columbia, because those jurisdictions challenged the constitutionality of the administration's actions.
However, the Supreme Court's decision itself is purely procedural. The justices did not rule on the legality of the order itself. Rather, Justice Sonia Sotomayor, joined by Justice Elena Kagan, emphasized in her dissent: "Today's decision does not address whether the President's attempts to interfere with state election administration in November 2026 are lawful." The majority merely deferred the merits, finding Judge Talwani's action premature before federal agencies had completed preparing an implementation plan.
The White House immediately claimed victory, calling the provisions of the order "common-sense measures." Caroline Leavitt, White House press secretary, pointed to the legality of the administration's actions. Shortly after the decision, the Postal Service issued final rules for implementing the measure.
Nevertheless, the legal battle is far from over. In a second case filed by a coalition of voting rights organizations, an injunction remains in effect. Parts of the order remain blocked, and Democrats promise new lawsuits aimed at fully invalidating the initiative.
New York Attorney General Letitia James, who led the coalition of states challenging the order, called the court's decision "a painful blow, but not the last word" and vowed to continue the fight. California Governor Gavin Newsom, whose state was the lead plaintiff, announced preparation of a new lawsuit, emphasizing the state's commitment to the principle: "Every eligible voter gets a mail-in ballot here — and we will fight for that."
Donald Trump has repeatedly criticized mass mail-in voting during his second term, claiming without evidence of widespread fraud. His administration is also promoting the SAVE America Act, which introduces even stricter restrictions: requiring documentary proof of citizenship at registration and voter ID at the polls. The bill passed the House in February 2026, but in the Senate it faced a filibuster by Republicans, who lack a sufficient majority to overcome Democratic resistance.
Practical challenges compound the legal ones. Experts point out that the timeline is catastrophic: the November elections are just over three months away, and many states have already begun sending out ballots. Even administration supporters admit that full implementation of the order in this election cycle is unlikely. It would impose chaos on the system, disenfranchising potentially millions of Americans who submitted applications hoping to receive mail-in ballots under current law.
Justice Ketanji Brown Jackson, the second liberal voting against the majority, in sharper terms accused the conservative majority of deliberately creating chaos before the election through the delay of proceedings. Her objection reflects fears that the procedural maneuver conceals a deeper political calculation.
The battle in the courts continues, and its outcome will determine not only the future of mail-in voting but also the balance of power between the federal government and states in election administration — a question that the American Constitution leaves largely in the hands of states. The final word has not yet been said, but the window of opportunity for changes before the November elections is rapidly closing.
