Kiobel v. Royal Dutch Petroleum Co.: The Supreme court and the Alien Tort Statute

The U.S. Supreme Court has finally decided Kiobel v. Royal Dutch Petroleum Co. It is the Court’s second modern decision applying the cryptic Alien Tort Statute (ATS), which was enacted in 1789. Since the 1980 court of appeals decision in Filartiga v. Pena-Irala permitting a wide of range human rights cases to go forward under the statute’s auspices, the ATS has garnered worldwide attention and has become the main engine for transnational human rights litigation in the United States. The statute itself and the decisions that it generates also serve as state practice that might contribute to the developing customary international law of civil universal jurisdiction, immunity for defendants in human rights cases, the duties of corporations, and the right to a remedy for violations of fundamental human rights. During the 1990s, the ATS became the focal point for academic disputes about the status of customary international law as federal common law. Indeed, to the extent that the “culture wars” have played out in U.S. foreign relations law, the ATS has been their center of gravity.
