State of California v. Trump, No. 1:26-cv-11581-IT (D. Mass.). Twenty-three states and the District of Columbia challenged Sections 2, 3, and 5 of Executive Order 14399, “Ensuring Citizenship Verification and Integrity in Federal Elections,” 91 Fed. Reg. 17125 (Mar. 31, 2026), as ultra vires and unconstitutional. On June 25, 2026, Talwani granted the plaintiff states’ motion for summary judgment. The California Attorney General’s release and the later Supreme Court appendix describe the relief: she declared core provisions legally void and enjoined agency defendants (not the President) from implementing Sections 2 and 3 in the plaintiff jurisdictions for federal elections on or before November 3, 2026.
Section 2, as described in that opinion, directed Homeland Security work on citizenship / eligibility lists. Section 3 directed the Postal Service on mail-ballot design, lists, and transmission. Summary judgment is a merits ruling at the district court. It is not a Supreme Court holding. The First Circuit refused a stay on July 25. The Supreme Court stayed this injunction on August 24, 2026.
