The Supreme Court granted certiorari on April 3 to decide whether Jordan-based Arab Bank may be liable for claims including allegations that its New York branch processed transactions for known terrorists. While the central issue before the Court will be the scope of the Alien Tort Statute (“ATS”) – namely whether it permits corporate liability for violations of international law – Jesner v. Arab Bank also illustrates how alleged AML/BSA failures can lead to yet another avenue for secondary legal liability for financial institutions, as we previously have noted in other contexts. Depending on the outcome of the Court’s opinion in Jesner, such U.S. exposures may extend to foreign financial institutions even when the alleged conduct occurs primarily abroad.
