Voting Rights Groups Move to Block Newly-Finalized Mail Ballot Rule
BOSTON — Voting rights organizations today supplemented the complaint in their lawsuit challenging President Trump’s executive order restricting mail voting to add claims against the U.S. Postal Service’s (USPS) newly-finalized mail ballot rule. The groups simultaneously asked a federal court to immediately block USPS from implementing that rule for the November midterm elections.
The plaintiffs in this case, League of Women Voters of Massachusetts v. Trump, are 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, Asian Americans Advancing Justice – AAJC, and LatinoJustice PRLDEF.
“USPS’s decision to rush this blatantly unconstitutional rule into effect just weeks before an election is the latest step in a rollout that has sown confusion at every turn and now threatens to disenfranchise voters who did everything right. This is chaos by design, and voters are the ones who will pay for it,” said Sophia Lin Lakin, director of the ACLU's Voting Rights Project. “No administration should be able to manufacture confusion around how we vote and undermine confidence in our elections in the process. Rather than serving voters, this rule threatens access to the ballot and treats voters as collateral damage. We will continue to use every legal tool available to block this illegal power grab and ensure voters can cast mail ballots with the confidence that their votes will be counted.”
On Aug. 11, 2026, the court issued an order in League of Women Voters of Massachusetts v. Trump, blocking USPS from implementing Section 3 of the executive order for the upcoming Nov. 3 midterm elections.
The Supreme Court later stayed a different court order issued in the separate Trump v. California case blocking implementation of the executive order. Of note, the Supreme Court did not decide whether President Trump has the legal authority to impose these restrictions or whether the USPS rule is lawful; it simply held that it was premature for the California plaintiffs to bring that case.
Earlier this afternoon, the court vacated the Aug. 11 injunction issued in League of Women Voters Massachusetts on the same narrow basis. Acknowledging that “Plaintiff Organizations have substantial arguments that might persuade the Supreme Court to reach a different result if Plaintiff Organizations have an opportunity to present them,” the court found “that in light of the Supreme Court’s decision in Trump v. California, Plaintiff Organizations are not likely to prevail as to ripeness without amending their complaint to reflect the fact that a Final Rule has now issued.” Plaintiffs have now supplemented their complaint to do exactly that, adding challenges to the newly finalized mail ballot rule and seeking emergency relief on those claims immediately.
In their papers, the plaintiff organizations argue that USPS’s newly-finalized mail ballot rule violates the Constitution’s separation of powers, which put the states and Congress in charge of election administration rules, not USPS or the president, as well as a number of the laws that govern how USPS operates.
All of these violations are causing irreparable harm to plaintiff organizations, their members, and the voters they serve. The harm is particularly acute as there are now less than 70 days before the November midterm elections, which is why the plaintiff organizations are asking for emergency relief.
After filing, counsel and plaintiffs released the following statement:
“The court has already found that the executive order unconstitutionally usurps the authority of the states and Congress to regulate elections, and the newly-finalized rule eliminates any doubt about the harms stemming from these unlawful acts. Implementing the newly-finalized rule less than 70 days before the general election would dramatically impair plaintiffs’ core voter engagement work and pose a grave risk of disenfranchisement. We are asking the court for emergency relief to prevent this harm and to affirm the public’s confidence in the systems voters rely on to conduct our elections.”
