In the United States and most European nations, aviation law is considered a federal or state-level concern and is regulated thereby at that level. In the U.S. states cannot govern aviation matters in most cases directly but look to Federal laws and case law for this function instead. For example, a court recently struck down New York's Passenger Bill of Rights law because regulation of aviation is traditionally a federal concern. Aviation law, however, is not in the United States held under the same Federal mandate of jurisdiction as admiralty law; that is, which the United States Constitution provides for the administration of admiralty, it does not provide such for aviation law.
Space law. which governs matters in outer space beyond the Earth's atmosphere, is a rather new area of law but one that already has its own journals and academic support. Expectedly, much of space law is connected to aviation law.
