U.S. DEPARTMENT OF THE INTERIOR; DOUG BURGUM, in the official capacity as Secretary of the Interior; NATIONAL PARK SERVICE; JESSICA BOWRON, in the official capacity as the Official Exercising the Delegated Authority of the Director Before Barron, Chief Judge Gelpí and Rikelman, Circuit Judges

Court: United States Court of Appeals for the First Circuit Filed: 2026-07-02 The First Circuit granted the Department of the Interior’s motion to stay the district court’s June 12, 2026, order that had preliminarily enjoined the implementation of Secretary’s Order No. 3431 and required the restoration of interpretive materials at National Park Service sites. The court held that the Department satisfied the four-factor test for a stay established in *Nken v. Holder*, primarily because it made a strong showing that the district court erred in finding the plaintiffs likely to suffer irreparable harm, which is a prerequisite for preliminary injunctive relief under 5 U.S.C. § 705 and general equitable principles. The court applied the standard requiring a movant to demonstrate that irreparable injury is “likely” and grounded in evidence rather than conjecture or unsubstantiated fears. It concluded that the plaintiffs failed to meet this burden because their claimed harms—such as frustration of organizational missions, reputational damage, and loss of membership—were either not traceable to specific directives in the Secretary’s Order or were speculative regarding independent actors’ choices. Furthermore, the court found that the district court improperly relied on generalized public harm and the alleged educational losses of a single member who had no concrete plans to visit the specific parks identified as affected, noting that no changes had actually been made to materials at those sites. Because the plaintiffs could not demonstrate likely irreparable harm, the Department was deemed likely to succeed on the merits of its appeal challenging the district court’s ruling. The practical consequence is that the district court’s preliminary injunction and order to restore interpretive materials are suspended pending the resolution of the Department’s appeal on the merits. The National Park Service may resume implementation of Secretary’s Order No. 3431, including the review and potential removal or revision of interpretive materials deemed inconsistent with Executive Order 14253, while the underlying legal challenge proceeds in the First Circuit.
