The First Circuit denied motions filed by federal defendants and intervening states seeking a stay of a district court’s injunction pending appeal. The court held that the government failed to make a strong showing that it is likely to succeed on its arguments that the Plaintiff States lack Article III standing or that their claims are unripe. Applying the four-factor test from *Nken v. Holder*, the court found that the government did not demonstrate a likelihood of success regarding standing because the Executive Order (EO) 14399 inflicts concrete, particularized, and imminent injuries on the Plaintiff States. The court identified three specific injuries: (1) current “planning and compliance costs” resulting from the immediate need to divert staff resources and alter election administration processes to comply with the EO’s directives for upcoming September and November 2026 elections; (2) certainly impending financial harm due to the requirement that states purchase new mail-in ballot envelopes conforming to new USPS design rules, rendering previously purchased envelopes unusable; and (3) a credible threat of criminal prosecution against state and local officials who fail to comply with the EO’s voter eligibility verification requirements, which conflict with existing state laws. The court distinguished these facts from cases like *Clapper* and *Trump v. New York*, noting that the EO explicitly targets states and imposes immediate deadlines that force action, rather than relying on speculative future contingencies. Additionally, the court rejected prudential ripeness arguments, finding the legal issues regarding the President’s constitutional authority were not dependent on further factual development. Regarding the remaining stay factors, the court concluded that a stay would not be in the public interest because enforcing the EO would likely cause voter confusion and disenfranchisement, and there is no public interest in perpetuating unlawful government action. The court also found that the irreparable injury claimed by the government regarding operational confusion was speculative and conclusory. Consequently, the district court’s injunction preventing federal defendants from implementing Sections 2 and 3 of the EO for federal elections on or before November 3, 2026, in the Plaintiff States remains in effect.
