A federal judge has blocked President Donald Trump's executive order altering mail-in voting procedures, ruling that its immediate implementation threatens to disenfranchise millions of voters ahead of the November 2026 election.

Judge Indira Talwani of the U.S. District Court for the District of Massachusetts issued the order, as reported by AllRise News reporter Adam Klasfeld. In her ruling, she wrote that "the court finds [...] that immediate implementation of the Final Rule issued less than seventy days before the November 2026 election threatens disenfranchisement of millions of United States citizens who seek to vote by mail."

The stakes are substantial: mail-in voting has become a major channel for ballots in recent federal elections, with tens of millions of voters casting ballots by mail in 2020 amid the pandemic, and postal ballots remaining a significant share of the vote in subsequent cycles. Any change to how the Postal Service handles those ballots therefore affects a large portion of the electorate, particularly in states that conduct elections largely or entirely by mail, such as Oregon, Washington, Colorado, Utah, Hawaii, and Nevada.

The executive order, which critics described as an "experiment" that could result in valid ballots being tossed, targeted how the U.S. Postal Service handles mail-in ballots.

The Constitutional Argument

According to Klasfeld, the judge's broader reasoning is that the Constitution simply "does not grant the President any specific powers over elections."

"Broadly, the Constitution vests the President with 'executive Power' and commands him to 'take Care that the Laws be faithfully executed[.]' The President 'plays no direct role in the process' of appointing electors, 'nor does he have authority to control the state officials who do,'" Talwani wrote.

The judge added that the Supreme Court has observed that "the President's power to see that the laws are faithfully executed refutes the idea that he is to be a lawmaker."

Under the U.S. Constitution, states primarily administer elections, while Congress may alter state regulations regarding the "Times, Places and Manner" of congressional elections. The Constitution assigns the President no direct role in election administration. This division of authority has been the central legal battleground in a broader wave of litigation over Trump-era election directives, with federal courts in multiple districts weighing challenges to executive actions touching voting rules.

Timeline of the Litigation

The ruling concludes deliberations that began Thursday over whether to extend an earlier injunction indefinitely. Talwani had previously blocked the Postal Service from implementing the plan for 14 days, a period that would have expired on September 10.

Before her Friday decision, Talwani pressed Justice Department attorneys and a coalition of Republican states with pointed questions about how they believed the new rule could be implemented on the eve of early voting in many states. Her questions echoed concerns raised by a broad coalition of nonprofits and Democratic states that the Postal Service could chaotically reject thousands of valid ballots if allowed to proceed with Trump's new rule.

The case was litigated before the U.S. District Court for the District of Massachusetts, where Talwani, an Obama-era appointee, serves as a district judge. As with other district-court rulings on election rules, the decision is subject to appeal — in this instance to the U.S. Court of Appeals for the First Circuit — and could ultimately reach the Supreme Court, which in recent election cycles has repeatedly been asked to decide emergency election-law disputes under tight deadlines.
