The US Supreme Court issued an emergency, unsigned order on Monday rejecting the Trump administration's attempt to enforce a new US Postal Service (USPS) regulation on mail-in ballots for the upcoming midterm elections. The ruling leaves untouched a nationwide preliminary injunction from US District Judge Indira Talwani, which lets states keep sending and processing mail ballots under their own existing rules. The vote was 7–2, with Justices Clarence Thomas and Samuel Alito dissenting and Justice Brett Kavanaugh writing separately to agree the regulation had to be blocked for this election cycle. That a court with a 6–3 conservative majority produced such a result says something about how far the administration had overreached.
Under the blocked rule, states would have had to submit lists of eligible voters to a newly built federal portal, which the Postal Service would then use to screen every ballot envelope against federal eligibility data before delivery. States also had to adopt uniform, USPS-approved envelopes with individual tracking barcodes. In effect, the federal government would have inserted itself as gatekeeper between voters and their ballots, a role the Constitution assigns to state legislatures and Congress, not to the executive branch or the agencies under it.
This was Trump's second attempt at the same goal. Having failed to move the SAVE America Act through Congress, he signed an executive order in March directing federal agencies and the Postal Service to build mail-voting rules of their own, resting as ever on unproven claims that mail-in voting invites fraud. The Court's order marks another defeat in what has become a pattern. The administration has already lost 23 of 30 Justice Department lawsuits seeking unredacted voter rolls from the states, and this ruling folds neatly into that losing streak.
The justices leaned on three grounds. The first was structural: election administration belongs to the states, and a federal agency cannot simply claim jurisdiction because it happens to handle the mail. The second was timing. Several states, including North Carolina, Alabama and Wisconsin, had already begun mailing ballots when the rule was due to take effect, and the Court's own Purcell principle counsels strongly against upending election procedure this close to voting day. Kavanaugh's concurrence captured the practical objection neatly, calling it arbitrary to force officials into a new system on the eve of an election even if the Postal Service held some underlying statutory authority. The third ground was operational. Civil rights groups and election officials told the Court the verification portal was still unfinished and that barcode errors risked discarding millions of valid ballots, a warning seven Republican state election officials themselves put in writing.
There was also a practical reason the Court could not simply wait for its October sitting. With midterm voting already underway and statutory deadlines looming, including the five-day window for sending overseas and military ballots, election officials needed clarity immediately rather than legal limbo stretching into autumn. The emergency docket exists precisely for moments like this, when a delayed answer would itself become the harm.
What the ruling protects, beyond procedure, is the roughly one third of the American electorate that votes by mail, whose ballots will now go out and come back under rules they already understand. What it signals, beyond this one case, is that a court built by conservative appointments is not prepared to bend constitutional structure to accommodate an administration's preferred method of counting votes. Roberts, Kavanaugh and Barrett siding with the liberal bloc is a clear indication that the court was unlikely to go along with executive claims on elections.
None of this, however, ends the campaign to take over the electoral process. The Trump administration continues other pressure campaigns—such as Justice Department voter data subpoenas, Homeland Security threats regarding federal funding and ongoing public commentary casting doubt on election integrity.
