Supreme Court Allows Trump Administration to Advance Mail-In Voting Restrictions

The U.S. Supreme Court on 25 August 2026 cleared the way for the Trump administration to implement part of an executive order restricting mail-in voting.

In a 6-3 decision the justices lifted a lower-court injunction that had blocked the order. The executive order directs the Department of Homeland Security to create state-by-state lists of eligible U.S. citizen voters and instructs the Postal Service on who may receive mail ballots.

President Trump has repeatedly claimed, without evidence of widespread fraud, that mail-in voting is vulnerable to abuse. The order aims to limit ballots to those on the federal citizenship lists.

With some states scheduled to begin mailing ballots within weeks, the practical effect before the November midterms remains uncertain. Election officials in several states have said implementation on the current timeline is difficult.

The three liberal justices dissented. Lower courts had found the order exceeded presidential authority over state election administration. The Supreme Court’s unsigned order allows the administration to proceed while the underlying litigation continues.

Civil-rights groups and Democratic state officials have argued the measure will suppress legitimate votes. Republican officials have welcomed the ruling as a step toward greater election integrity.

The decision forms part of a broader series of election-related cases before the Court this term. Separate litigation over voter-ID measures and other procedural changes is pending in multiple states.

Whether the citizenship lists can be compiled accurately and distributed in time for the midterms will be tested in the coming weeks. States that rely heavily on mail voting face the largest operational questions.

The ruling does not resolve the constitutional questions permanently. Full briefing and argument on the merits remain possible later. For now the administration may move forward with the lists and related Postal Service guidance.
