US Supreme Court strikes down Postal Service mail-ballot restrictions

A final pre-election ruling

The United States Supreme Court struck down the Postal Service's new mail-ballot rule on September 14, stopping a central element of President Donald Trump's election-policy programme before the November midterms. Axios reported that the justices divided 7-2. The decision reverses an earlier procedural opening the court had given the administration and is likely to govern the current election cycle.

States can therefore continue mailing ballots under their established systems. The timing was critical: Alabama, North Carolina and Wisconsin had already begun sending ballots, while election administrators argued that a nationwide redesign could not be implemented safely within weeks. Nearly one-third of US voters use mail voting, giving the dispute consequences beyond the states and organisations that brought the litigation.

What the blocked system required

The administration's plan called for standardised ballot-envelope features, unique tracking identifiers and state lists of people authorised to receive mail ballots. The Postal Service could decline to transmit ballots for voters absent from a state-specific participation list. Those elements originated in Trump's March executive order and were later incorporated into a final postal rule challenged after its publication.

The White House presented the system as a citizenship-verification and election-integrity measure. Challengers argued that the executive branch and Postal Service were assuming authority that the Constitution assigns principally to states and Congress. A Postal Service whistleblower also warned that hurried construction of the verification portal and barcode system could place legitimate ballots at risk, although that warning was not itself the court's holding.

The ruling narrows immediate uncertainty

Lower courts had repeatedly blocked enforcement, but an earlier Supreme Court order addressed timing and standing rather than the final rule's legality. The September 14 ruling came after publication of the completed postal regulation, allowing the justices to confront the operative system. At least one justice who joined the result disagreed with parts of the challengers' legal case, according to Axios.

The immediate consequence is administrative continuity rather than a new voting system. Election officials can use existing envelopes, voter databases and delivery arrangements as ballots go out. The broader contest over federal election power will continue through other lawsuits and legislation, but reinstating this particular rule before November is now highly unlikely. Attention shifts to implementation of state procedures and any further attempts to reshape election administration.
