The Supreme Court ruled 6-3 to lift a lower-court injunction blocking President Trump's executive order restricting mail-in ballots, a decision that lets federal agencies begin enforcement just weeks before November's midterm elections.
The unsigned ruling, issued Monday in Alabama v. California, found that a federal district judge in Boston had overstepped by blocking the order entirely. Twenty-three states and Washington, D.C., had sued to stop the directive, but the court's conservative majority concluded the states lacked standing because the executive order imposes requirements only on federal agencies, not on state governments. Fox News reported that the U.S. Postal Service and the Department of Justice both said they would move immediately to implement the revised restrictions.
The order, titled "Preserving and protecting the integrity of American elections," directs three federal agencies to tighten controls around mail-in voting. The Department of Homeland Security must compile citizenship-based voter lists for every state. The Postal Service must deliver mail-in ballots only to individuals who appear on those DHS-approved lists. And the Justice Department is directed to prosecute election officials who issue ballots to ineligible voters. The executive order cites two federal statutes, 18 U.S.C. 1015 and 18 U.S.C. 611, that prohibit foreign nationals from registering to vote or casting ballots in federal elections.
The majority's reasoning turned on a narrow procedural point: standing. The court wrote that the order "directs the Secretary of Homeland Security to take appropriate action to create and distribute State Citizenship Lists," calling it "an internal directive from the President to a subordinate." Because it "imposes no obligations on the States," the majority held, the challenger states "suffer no concrete harm from it, and without concrete harm, there is no standing."
Justices Sonia Sotomayor, Elena Kagan, and Ketanji Brown Jackson dissented. The Democrat-led states that brought the challenge warned the court that lifting the injunction would invite confusion into mail voting processes right before a closely contested November election, the Washington Examiner reported.
The ruling is procedural, not final. The court made clear it was not deciding whether the executive order itself is lawful. The unsigned opinion noted, regarding the merits, "On that score, time will tell." A separate nationwide injunction blocking USPS enforcement of the order's tighter mail-voting rules remains in place, and the underlying constitutional dispute will continue in lower courts.
That distinction matters. The administration won the right to move forward, but opponents still have legal avenues to challenge the order on its merits. For now, though, the practical effect is clear: with states beginning to send ballots in early September, DHS can start distributing citizenship lists and the Postal Service can begin screening ballot deliveries against them.
Monday's decision extends a pattern. The Trump administration has brought a historic number of emergency petitions to the Supreme Court since returning to office, and it has won an unusual share of them. The administration's willingness to escalate disputes to the high court on an emergency basis, and the court's willingness to grant relief, has become a defining feature of this term.
The DOJ and a coalition of Republican-led states filed the emergency petition after the D.C. Circuit upheld a district court's block on the order. The administration had appealed the original injunction in July. Monday's result reversed both lower courts on the standing question, though it left the deeper legal fight unresolved.
The administration has faced mixed results on other fronts at the high court. Earlier this year, the justices struck down IEEPA-based tariff levies, forcing the return of $100 billion in refunds, a reminder that the court's emergency docket can cut both ways.
The executive order itself lays out the administration's rationale bluntly. It states that "several Federal laws" already ban foreign nationals from registering or voting in federal elections, then adds: "Yet States fail adequately to vet voters' citizenship, and, in recent years, the Department of Justice has failed to prioritize and devote sufficient resources for enforcement of these provisions."
A White House fact sheet framed the directive in similar terms, stating that "President Trump is taking decisive action to prevent non-citizens from voting in Federal elections and to protect the security of mail-in and absentee ballots."
Trump himself has been more direct. In comments to Fox News, he pointed to California's all-mail voting system as a particular concern.
"You know, they don't have voting booths; everything's by mail. I don't think a Republican can win in California unless you pass the Save America Act."
He added: "They're going to have to get rid of mail-in voting." Trump has referenced the 2026 Los Angeles mayoral race primaries as an example, citing what he described as a suspiciously high volume of mail-in ballots arriving after election night. Fox News Digital noted it has not reviewed any particular case of election fraud tied to the LA mayoral race.
The Supreme Court has also been active on other emergency petitions involving the administration's construction priorities. The justices recently allowed White House ballroom construction to proceed while weighing a separate appeal, another case that tested the boundaries of executive authority and lower-court injunctions.
National Review's Dan McLaughlin argued the court "was right to conclude that a rogue district judge had gone too far in trying to stop Trump from doing anything," but noted the justices stopped short of addressing the core dispute around Section 3 of the order, the provision directing the Postal Service to restrict ballot delivery.
That unresolved question looms over the coming months. A separate nationwide injunction still blocks USPS from enforcing the tighter mail-voting rules. If that injunction holds, the practical impact of Monday's ruling could be limited to DHS list-building and DOJ enforcement priorities rather than the headline restriction on ballot delivery.
The legal path forward remains tangled. Lower courts will take up the merits. States will press their constitutional arguments. And the administration will push to implement as much of the order as it can before voters start receiving ballots.
Meanwhile, the administration has shown no hesitation in returning to the Supreme Court's emergency docket when lower courts block its agenda. The pattern of emergency petitions has become routine, and, for the administration, routinely successful.
The Save America Act, which Trump referenced in his Fox News comments, would further tighten voter-ID requirements and narrow the scope of mail-in voting. Its current legislative status remains unclear. But with Monday's ruling, the administration has won the ability to act through executive authority while Congress debates.
The Trump administration's aggressive use of emergency petitions at the Supreme Court has drawn criticism from the left and praise from the right. Monday's mail-ballot ruling fits the pattern: a procedural win that clears the path for action, even as the deeper legal questions remain open.
Twenty-three states tried to stop a president from enforcing federal law against noncitizen voting. Six justices told them they hadn't earned the right to complain. The midterms are ten weeks away, and the ballots will go out on the administration's terms, not theirs.
