Supreme Court Blocks Trump Mail Ballot Rules for Midterms

The Supreme Court on Monday night refused to let the Postal Service impose new mail voting restrictions for the November 2026 midterm elections.

On Monday night, less than two months before the November midterms, the Supreme Court declined to lift a preliminary injunction blocking the U.S. Postal Service from enforcing new mail ballot rules. In a brief, unsigned order, the justices wrote that the "Government is unlikely to succeed on the merits of its challenge" to Judge Indira Talwani's injunction and that the equitable factors for emergency relief "do not favor a stay." The decision leaves in place a lower court ruling barring USPS from requiring states to submit voter lists through a federal portal or to adopt new ballot envelope designs with trackable barcodes.

The ruling marks a sharp reversal from late August, when the Supreme Court had put Judge Talwani's earlier order on hold on narrow procedural grounds, finding it premature because the Postal Service had not yet issued its final rules. The administration's Solicitor General first withdrew one emergency request, then filed a new one seeking to block the injunction.

Justice Brett Kavanaugh supplied the vote that made the outcome possible, and his reasoning was notably narrow. According to SCOTUSblog, Kavanaugh wrote a one-paragraph concurrence agreeing with the denial, suggesting the Postal Service "might have the power to issue the rule" but that election officials "do not have sufficient time to reasonably implement the rule before" the November elections. NPR similarly reports Kavanaugh called it "at least a fair prospect" that the rule falls within USPS's statutory authority, while saying applying it in 2026 would be "arbitrary and capricious" under the Administrative Procedure Act. That framing leaves the underlying legality open for future elections while blocking enforcement now — a distinction that means the legal fight is likely to continue after November.

The case turned heavily on practical impossibility, with unusually bipartisan support for blocking the rule. NPR reports that Republican election officials, including from Utah, signed a Supreme Court brief warning that implementing the plan now would "almost certainly lead to mistakes, delays, and confusion." PBS reports that election officials said there was simply no way to carry out a complete overhaul weeks before the midterms, with Alabama, North Carolina and Wisconsin already mailing ballots. Votebeat reports an anonymous USPS whistleblower called the system "secretive, rushed, chaotic, and fundamentally flawed," warning that a single bar code error could cause an entire batch of ballots to be rejected, potentially preventing millions of Americans from voting. NPR adds that in a court filing, USPS admitted the technology to implement the rule was not yet available.

PBS reports that under the plan, USPS could have refused to deliver ballots from states that did not comply with new envelope designs and voter list submissions. Washington Secretary of State Steve Hobbs said election workers can now continue "without having to upend our election processes," while Colorado's Jena Griswold called the ruling "a major victory for Colorado and American democracy." California Governor Gavin Newsom, whose state led the multi-state lawsuit, said "California stood up for democracy and we won," and Attorney General Rob Bonta called the decision "a powerful affirmation of the rule of law."

The ruling settles the question only for 2026. Votebeat reports the decision leaves open whether the restrictions are legal overall and could be implemented in future elections, and the concurrence's structure suggests a majority is skeptical of the rule itself, with only two justices joining a dissent arguing the rules should be allowed to proceed. Alito, joined by Thomas, argued the government had made the showings necessary for a stay and that USPS "has broad authority to regulate the mail," while blaming courts and challengers for the last-minute timing. Democratic officials pledged continued vigilance: New York Attorney General Letitia James said, per NPR, that her state will "keep fighting to make sure every eligible ballot is counted come November." With roughly fifty days until Election Day, election officials nationwide can now process mail ballots under the systems they have used for years.
