Pursuant to a contract with the Indonesian government, Exxon Mobil Corporation…operated a large natural gas extraction and processing facility in the Aceh province of Indonesia in 2000–2001. Plaintiffs-appellants are fifteen Indonesian villagers from the Aceh territory…For the reasons that follow, we conclude that aiding and abetting liability is well established under the [Alien Tort Statute (“ATS”)]. We further conclude under our precedent that this court should address Exxon’s contention on appeal of corporate immunity and, contrary to its view and that of the Second Circuit, we join the Eleventh Circuit in holding that neither the text, history, nor purpose of the ATS supports corporate immunity for torts based on heinous conduct allegedly committed by its agents in violation of the law of nations.
