In 2003, three Japanese citizens, six U.S. and Japanese environmental associations along with Okinawa residents on behalf of the dugong as plaintiffs filed a claim against the U.S. Department of Defense at the U.S. District Court in northern California. The plaintiffs claimed that the U.S. Marine base construction scheme in Henoko Bay would destroy the habitat of marine mammals like the dugong. For local Okinawa residents, the dugong has been integral part of their cultural and historical heritage, and the planned military facility would violate the U.S. National Historic Preservation Act and the Administrative Procedure Act. This military facility was planned to replace the existing and controversial military base in Futenma as the location is within residential areas and some accidents had plagued residents for a long time. This replacement plan, however, met strong opposition from environmental activists and Okinawa people in general partly because of the impact on the dugong. They also opposed because Okinawa people had been overburdened by American military presence for too long. In 2008, the judge of the district court dismissed the standing of the dugong in this case, but mostly agreed with the plaintiffs' argument, ordering the DOD to conduct proper impact assessment prior to the commencement of the construction. Prime Minister Shinzo Abe and his cabinet, however, are now determined to continue construction despite the strong opposition from residents. The newly elected Okinawa prefecture governor has strongly acted against this Henoko plan, sharply confronting with Abe and Chief Cabinet Secretary Suga. The dispute has not been resolved yet.
