NYU Law professor Samuel Estreicher and Hofstra Law professor Julian G. Ku comment on the U.S. Supreme Court’s recent decision in Nestlé v. Doe, in which the Court held that mere “corporate activity” within the United States is not enough to satisfy the general presumption against the extraterritorial application of federal law. Professor Estreicher and Ku point out that questions about the scope of future ATS claims or corporate liability may never be resolved if the vast majority of ATS claims are dismissed as a result of the Court’s reinvigorated extraterritoriality test.
