U.S. Supreme Court Blocks Postal Service From Restricting Mail Ballots
WASHINGTON – In a major win for voting rights, election integrity, and democracy, the U.S. Supreme Court today left in place a preliminary injunction that blocks the U.S. 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 Nov. 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.
The USPS rule that has been blocked by the courts would have operationalized President Trump’s March 31 executive order to restrict mail voting.
The injunction stems from a lawsuit filed by a coalition of nonpartisan voter service and civic organizations: the League of Women Voters of Massachusetts, League of Women Voters, Association of Americans Resident Overseas, U.S. Vote Foundation, OCA - Asian Pacific American Advocates, and Delta Sigma Theta Sorority, Inc. They are represented by the American Civil Liberties Union, ACLU of Massachusetts, Brennan Center for Justice at NYU Law, Legal Defense Fund (LDF), Asian Americans Advancing Justice – AAJC (Advancing Justice – AAJC), and LatinoJustice PRLDEF.
Attorneys for the plaintiffs released the following statement:
“This ruling is a critical step to ensuring free and fair elections this November by maintaining access to mail voting for millions of eligible voters across the United States and lifting the dire threat that the Postal Service would disenfranchise them. Mail voting is safe, secure, and reliable — and the Trump administration has presented no evidence to the contrary, as the courts have repeatedly recognized. We will remain vigilant in countering threats to free and fair elections and ensuring that every eligible voter is able to cast a ballot and have it count.”
