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. 

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, US 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.

Plaintiffs and counsel in the case issued the following statements:

Celina Stewart, Esq., CEO, League of Women Voters: 

"Today, the Supreme Court refused to allow the federal government to throw our elections into chaos just weeks before Election Day. The Postal Service exists to deliver Americans’ mail — not to rewrite election rules, demand voters’ personal information, or decide which ballots make it through the system. This was an extraordinary attempt to interfere with voting in all 50 states, and voters should never have been put in this position. Voters should never be caught in the middle of a political power warfare. The League fought back, and we will keep fighting because the fundamental right to vote cannot depend on the whims of any president or federal agency. Voters decide elections. Period."

Celia Canavan, Executive Director, League of Women Voters of Massachusetts:

"The League of Women Voters of Massachusetts is pleased to see democracy prevail in today’s ruling. Access to a free and fair election is critical to voter participation — and protecting access to mail ballots and the vote-by-mail process is crucial to ensuring voter participation, and most importantly, voter confidence. We will continue to press forward to ensure that every eligible voter is able to cast their ballot however they choose this election season — and have that vote counted."

Attorneys for the plaintiffs: 

"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."

Doris Speer, President of the Association of Americans Resident Overseas: 

"The Supreme Court’s ruling is very welcome news for Americans living overseas. The USPS rule threatened mass confusion and chaos for voters abroad. Wherever American citizens live, the right to vote is fundamental. We are relieved that it will not be undermined in November for voters who rely on the mail to deliver their ballots."

Susan Dzieduszycka-Suinat, President and CEO, US Vote Foundation:  

"We are pleased that the rule will remain blocked through Election Day. US Vote Foundation represents Americans living abroad, military members stationed overseas, and their families. For some military members, ballots have already been sent. We are grateful that voters have certainty about the rules for this election cycle, especially for those of us who already face significant hurdles to participating in elections."

Thu Nguyen, Executive Director, OCA - Asian Pacific American Advocates stated: "This ruling stops, at least for the 2026 elections, an attempt to make voting harder for the people who already have the hardest time doing it. Asian Americans vote by mail at more than double the national average. The ruling reaffirms that the right to vote by mail doesn't belong to some Americans, it belongs to all of them."

Cheryl W. Turner, International President and Chair, National Board of Directors, Delta Sigma Theta Sorority, Incorporated 

"Today’s decision is consequential because it preserves stability and certainty for voters at a moment when the midterm elections are already underway. The Supreme Court’s decision ensures that new postal requirements will not be imposed in the final weeks before Election Day, disrupting established voting systems or creating new barriers for eligible voters who rely on the mail. Delta Sigma Theta Sorority, Incorporated, joined this litigation because fundamental voting rights demand vigilant protection, particularly when changes threaten to interfere with access to the ballot. This decision provides an important safeguard for voters in November’s election, and we remain steadfast in our commitment to protecting the right to vote."

Sophia Lin Lakin, Director of the ACLU’s Voting Rights Project:

"This administration keeps testing the limits of its power, as if the rules governing our elections are merely suggestions to ignore when they don't suit the president's agenda. But the Constitution gives states and Congress the power to set the rules for federal elections — not the president, and not the Postal Service. When the Postal Service tried to impose its own rules on mail voting just weeks before an election, the courts stopped it, and the Supreme Court has now left that ruling in place. The president does not run our elections, the Postal Service does not get to decide whose ballot counts, and voters — not the White House — will decide November's elections."
