A Jenner & Block team consisting of Partners Rachel Alpert, Adam Unikowsky, and Douglass Mitchell along with Associates Eric Petry and Kyle Tramonte recently assisted Mark Feldman and Professor Chiméne Keitner on submitting an amicus brief to the Supreme Court in Halkbank v. United States.
The brief argues that neither international law in the form of federal common law nor the Foreign Sovereign Immunities Act exempt foreign countries or their government organizations from criminal jurisdiction.
In their decision, the Supreme Court held that the Foreign Sovereign Immunities Act does not provide foreign states and their instrumentalities with immunity from criminal proceedings.
