Ms. Grosh is also one of the leads in defending the United States in the Certain Assets case brought by Iran before the International Court of Justice under the 1957 Treaty of Amity, in which Iran is challenging measures of the executive branch, Congress and the U.S. courts to assist U.S. victims in obtaining compensation from state sponsors of terrorism.
