US Supreme Court Blocks Postal Service From Restricting Mail Ballots

Court leaves a preliminary injunction in place through the November election; USPS cannot withhold mail ballots from voters 

September 14, 2026

WASHINGTON, DC — In a major win for voting rights, election integrity, and democracy, the US Supreme Court today left in place a preliminary injunction that blocks the US Postal Service (USPS) from enforcing key parts of a new rule that would have significantly restricted mail voting and disenfranchised voters who rely on mail ballots. The preliminary injunction will remain in place through the November 3 election.

The decision means that all 50 states can continue to use their existing processes for mail voting, which have proven for decades to be safe, secure, and reliable. Hundreds of thousands of mail ballots are already being delivered to eligible voters, with millions more to follow this month. Many Americans rely on mail voting because disability, distance, or work or caregiving schedules make it difficult or impossible to get to their polling site in person.

With the injunction in place, USPS cannot refuse to deliver mail ballots for the November election. Nor can it require states to upload personal voter information into its new and untested online portal.
