The US Supreme Court on Monday blocked the Trump administration's plan to impose sweeping restrictions on mail-in voting ahead of the November midterm elections, ruling that the United States Postal Service cannot implement new requirements that election officials and legal experts warned would upend voting for millions of Americans.

The case centered on a March 2026 executive order from President Trump requiring the USPS to only deliver mail-in ballots to voters who appear on each state's approved mail-in ballot list, effectively overhauling the decades-old infrastructure for absentee voting. Lower courts had already blocked the order, and the Supreme Court's decision to deny Trump's emergency appeal marks the final word — at least for this election cycle.

Election officials from both parties had warned that the restrictions would create chaos in the final weeks before an election, potentially disenfranchising voters who had relied on mail-in ballots for years. The ruling carries significant implications not just for the upcoming midterms but for the broader legal framework governing how Americans vote by mail.

The decision comes amid an intensifying battle over voting access in the US, with the Trump administration pushing to tighten election procedures while opponents argue the measures are designed to suppress voter turnout in key races.
