A federal court in the District of Columbia has dismissed a lawsuit filed by the Sierra Club seeking to force the U.S. Fish and Wildlife Service (FWS) to expand the designated critical habitat for the leatherback sea turtle, a listed endangered species. Sierra Club v. FWS, No. 1:11-cv-00993 (D.D.C. 3/19/13). The Sierra Club had administratively petitioned FWS to expand the leatherback’s critical habitat, and FWS had agreed that action was needed. When no revision had taken place by 2011, the Sierra Club sued to force FWS to take action. The court held that it lacked jurisdiction over the claims. It cited the lack of legislative standards to review FWS’s actions and concluded that FWS’s “determination is a decision committed to the agency’s discretion by law, and thus unreviewable under the Administrative Procedure Act.”
