...I summarize, Justice-by-Justice, some of the key issues raised by Supreme Court and the responses of the parties’ lawyers and the United States government as amicus curiae.

...Justice Samuel Alito focused in on the norm-identification process long established by Sosa v. Alvarez-Machain, which requires courts to consider whether the plaintiff has alleged an established rule of international law.

...Justice Neil Gorsuch was quite fixated on a 2011 law review article suggesting that the ATS was drafted in order to address situations in which the defendant hails from the United States... 

...Justice Anthony Kennedy stayed focused on the core question: does Sosa require plaintiffs to show that international law affirmatively recognizes a cause of action against corporations for international law violations? 

...Justice Stephen Breyer reasoned that Sosa and the treaties address both persons and entities.
