The First Circuit denied motions filed by federal defendants and intervening states seeking a stay of a district court injunction pending appeal. The court held that the movants failed to make a strong showing that they are likely to succeed on their arguments that the Plaintiff States lack Article III standing or that their claims are unripe. The court applied the four-factor test from *Nken v. Holder* for granting a stay, focusing primarily on the likelihood of success on the merits and irreparable injury. Regarding standing, the court affirmed the district court’s finding that the Plaintiff States suffered concrete, particularized injuries sufficient to establish Article III jurisdiction. These injuries included: (1) immediate planning and compliance costs incurred by states forced to divert staff resources to develop strategies for complying with the Executive Order’s directives; (2) certainly impending financial losses from having to replace already purchased mail-in ballot envelopes that do not meet the Executive Order’s design requirements; and (3) a credible threat of criminal prosecution against state and local officials for failing to comply with the Order’s voter eligibility verification mandates, particularly given the Order’s potential conflict with state laws regarding 17-year-old voters in primaries. The court distinguished this case from *Clapper v. Amnesty International USA* and *Trump v. New York*, noting that unlike those cases, the Executive Order here explicitly targets state officials and creates a direct, immediate dilemma requiring action before the upcoming September and November 2026 elections. Regarding prudential ripeness, the court found that the intervenor states failed to demonstrate that legal issues regarding the President’s authority under the Constitution required further factual development, as the core question was a purely legal one. The court also determined that the remaining *Nken* factors did not favor a stay: the federal defendants’ claims of irreparable harm were speculative and outweighed by the immediate harms the Plaintiff States would face if the injunction were lifted; the public interest favored maintaining the status quo to prevent voter confusion and potential disenfranchisement; and the government waived argument on the public interest factor. The practical consequence is that the district court’s injunction remains in effect, prohibiting federal defendants (excluding the President) from implementing Sections 2 and 3 of Executive Order 14399 regarding the November 3, 2026, and earlier federal elections within the Plaintiff States. The government may proceed with implementing the Order in other states or for elections occurring after November 3, 2026.
