"What is clear is that the majority today forecloses future reliance on Sosa and shuts the courthouse doors to almost any claimed violation of international law under the [Alien Tort Statute]."

"That includes torture. See, e.g., Filartiga v. Pena-Irala, 630 F. 2d 876, 878 (CA2 1980) (ATS suit brought by plaintiff alleging that his son had been kidnapped and tortured to death in retaliation for the plaintiff’s political beliefs). It includes forced labor. See, e.g., Licea v. Curacao Drydock Co., 584 F. Supp. 2d 1355, 1359 (SD Fla. 2008) (ATS suit alleging that the defendant trafficked Cubans to Curacao, held them in captivity, and forced them to work repairing ships and oil platforms). It also includes perhaps the most universally condemned crime in the modern era: genocide. See, e.g., Kadic v. Karadzic, 70 F. 3d 232, 236–237 (CA2 1995) (ATS suit alleging 'brutal acts of rape, forced prostitution, forced impregnation, torture, and summary execution, carried out by Bosnian-Serb military forces as part of a genocidal campaign'). 'Like the pirates of the 18th century,' whose conduct so concerned Blackstone and the First Congress, 'today’s torturers, slave traders, and perpetrators of genocide are "hostis humani generis, an enemy of all mankind."' Nestlé, 593 U. S., at 647 (opinion of SOTOMAYOR, J.). As to each of these offenses, as to each of these enemies of mankind, the majority decides that there is simply no way that a suit could possibly proceed without offending Congress. Noticeably absent from the majority’s analysis is any evidence that Congress would be offended by these suits. Of course, there may be reasons why allowing an individual ATS suit to proceed would be unwise. That possibility, however, should be addressed on a case-by-case basis...."
