League of Women Voters of Massachusetts et al. v. Trump, No. 1:26-cv-11549-IT (D. Mass.). On March 31, 2026, President Trump issued Executive Order 14399, “Ensuring Citizenship Verification and Integrity in Federal Elections,” 91 Fed. Reg. 17125. The order directed, among other things, that the United States Postal Service refuse to transmit mail ballots that did not meet new design and technology requirements and/or that were addressed to people whose names did not appear on lists provided to USPS.
On August 11, 2026, Talwani granted the plaintiffs’ renewed motion for a preliminary injunction (Doc. 170). The order enjoins the Postal Service, its Board of Governors, named governors, the Deputy Postmaster General, and the Postmaster General — including officers, agents, servants, and employees — from implementing, giving effect to, or enforcing Section 3 of the executive order with respect to the November 3, 2026 or any earlier federal election, including refusing to transmit mail-in or absentee ballots, or otherwise initiating or completing the Section 3 rulemaking for those elections. The injunction does not bar non-binding USPS guidance on ballot-mail envelopes. Plaintiffs were to post a $100 bond by August 18, 2026.
The memorandum states that, across the related cases, the federal government had declined to defend the constitutionality of the order’s directives and had asked courts to postpone review on standing and ripeness. A preliminary injunction is a temporary order. It is not a final judgment, not a criminal conviction, and not a Supreme Court holding. The Washington Times covered the order the same day as reporting. The Supreme Court’s August 24 stay in the separate California case did not, on its face, vacate this League injunction.
