US Supreme Court Deals Blow to Trump by Rejecting Mail-In Ballot Restrictions Ahead of Midterms

The US Supreme Court in Washington, DC, on September 1, 2026, delivered a setback to President Donald Trump by refusing to allow the US Postal Service to enforce a controversial rule targeting mail-in ballots.

In a conservative-majority court decision on Monday, justices declined to lift an order by US District Judge Indira Talwani that blocked the measure, complicating Trump’s push to restrict voting by mail prior to the November midterm elections.

The postal agency had adopted the regulation after President Donald Trump signed an executive order in March designed to tighten mail-in voting protocols. Under the directive, states were mandated to provide the Postal Service with lists of recipients and utilize ballot envelopes pre-approved by the agency. The Postal Service retained the authority to reject ballots failing to meet these standards or lacking association with registered voters on the provided lists.

Judge Indira Talwani previously issued an injunction halting the rule, concluding it likely violated the US Constitution and presented an impossible implementation challenge with the midterms fast approaching.

Following that ruling, the Trump administration filed an emergency request with the Supreme Court, urging permission to enforce what it termed an “important federal policy to protect the mails from being used to commit voter fraud.” Although the Supreme Court temporarily permitted the executive order to proceed on procedural grounds in late August, it deferred judgment on the policy's legality.

In its latest unsigned order, the court stated that the administration was “unlikely to succeed on the merits” of its legal challenge. Justices Samuel Alito and Clarence Thomas dissented, with Justice Samuel Alito arguing that certain plaintiffs lacked standing while others pursued claims described as a “Hail Mary pass.” Meanwhile, Justice Brett Kavanaugh joined the majority against the administration, though he suggested potential future support for the policy.

Critics have cautioned that these restrictions threaten to disrupt the delivery of thousands of ballots and potentially disenfranchise populations heavily dependent on mail-in voting, particularly in Democratic-leaning states. With states like Alabama, North Carolina, and Wisconsin already distributing ballots for the upcoming midterm elections, President Donald Trump continues to voice skepticism regarding mail-in voting security and repeats unproven allegations of widespread election fraud, despite utilizing mail-in voting himself during the 2024 election.
