US judge blocks Trump administration's bid to restrict mail-in voting

A federal judge in Boston has blocked a Trump administration effort to tighten mail-in voting rules, halting an executive order and related Postal Service steps that would have tied ballot delivery to federal voter data.

U.S. District Judge Indira Talwani issued the ruling on June 25, 2026, after a coalition of 22 states, the District of Columbia and voting rights groups challenged the plan in court. The decision is an immediate setback for the administration’s push to expand federal control over election administration ahead of the 2026 midterm cycle.

What the court stopped

The disputed executive order, signed on March 31, 2026, sought to create a federal voter list and use it to limit who could receive a mail ballot.

According to AP, Talwani blocked the provisions as unconstitutional, citing separation-of-powers concerns. The reporting indicates the judge found the administration could not use the executive branch to reshape election administration in that way.

The Guardian reported that the broader approach also would have required barcode tracking on ballot envelopes and sharing of voter-roll data with federal authorities.

The case centers on a basic fight over authority: whether the White House can impose new ballot rules on its own, or whether election administration remains a matter for states and Congress.

How the challenge unfolded

The lawsuit was brought by 22 states and the District of Columbia, with voting rights groups also involved in the challenge.

Their argument, as reflected in the reporting, was that the federal government cannot unilaterally change how mail ballots are handled or condition access to them on a federally compiled voter list.

The administration argued that federal verification would improve ballot integrity. The court did not accept that theory in the form advanced through the order and the related postal steps.

AP also reported that the ruling came a day after another federal court loss for the administration on a separate voting-related executive action, underscoring a broader legal pushback around election powers.

USPS remains part of the fight

The Boston ruling did not just touch the executive order. It also intersected with a separate Postal Service rulemaking dispute that could affect how absentee ballots are handled in practice.

The Guardian reported that USPS had proposed a rule requiring states to submit ballot and voter information through a federal portal.

The Daily Beast separately reported that the Postal Service would not mail absentee ballots under a new rule if states did not provide voter information, including names, addresses and ballot barcode numbers.

Those proposals mattered because they would have changed the mechanics of mail-ballot delivery, not just the legal language around elections.

For now, the ruling blocks the most aggressive version of that approach from moving forward.

What happens next

The ruling does not end the broader dispute over mail voting.

The administration could appeal or seek a stay. USPS could also still finalize, revise or withdraw the related rulemaking.

Another open question is whether any narrower version of the policy could survive if states voluntarily participate in federal verification assistance within congressional limits.

The immediate practical effect is that the challenged restrictions cannot be used to narrow mail-ballot access for the 2026 midterm cycle while the injunction stands.

Why it matters

Mail-ballot access is central to election logistics in many states, especially with the 2026 midterms approaching.

Any federal effort to limit access or add new tracking requirements could affect ballot printing, distribution, voter communication and election office planning.

The decision also fits into a larger set of election-related disputes over executive authority, federal verification and the limits of federal involvement in state-run elections.

For now, Talwani’s ruling keeps the challenged provisions from taking effect and leaves the administration to decide whether to keep fighting in court.
