Lujan v. Defenders of Wildlife

Wildlife protection organizations (plaintiffs) sued Secretary of the Interior Lujan (defendant), challenging a 1986 regulation limiting the Endangered Species Act's interagency consultation requirement to actions within the United States and high seas rather than including actions abroad, arguing the lack of foreign consultation increased extinction risk for endangered species; the district court initially dismissed for lack of standing, the court of appeals reversed and remanded, and after the district court then granted the plaintiffs summary judgment and an injunction, which the appellate court affirmed, the Secretary sought and obtained Supreme Court review.
