The U.S. Supreme Court’s decision in Kiobel v. Royal Dutch Petroleum Co. has not ended future debate about the scope and impact of the Alien Tort Statute (ATS). But the Kiobel Court did resolve at least one issue with surprising unanimity: both the opinion for the Court by Chief Justice John Roberts and the main concurring opinion by Justice Stephen Breyer refused to interpret the ATS as authorizing universal jurisdiction. All nine justices rejected decades of lower-court precedent and widespread scholarly opinion when they held that the ATS excluded cases involving purely extraterritorial conduct, even if the alleged conduct constituted acts that are universally proscribed under international law. In this short essay, I argue that the surprising death of universal jurisdiction reflects the triumph of the “separation of powers” critique of the ATS, which casts a skeptical eye on giving federal courts an independent role in the administration of both ATS lawsuits and cases involving international law more generally. I argue that this separation of powers critique of the ATS, which has found relatively little academic support, is a crucial reason why the Court unanimously rejected universal jurisdiction in Kiobel and why the Court may further restrict the ATS in future cases.
