We hold that New Jersey courts do not have jurisdiction to hear civil claims against foreign officials when the United States, through the State Department, has issued a suggestion of immunity (SOI) determining that those officials are entitled to conduct-based immunity. Therefore, we affirm a December 9, 2016 order dismissing plaintiff's civil complaint against six Israeli rabbinical judges and an official of the Rabbinical Religious Courts Administration of Israel after the State Department determined that the judges and official were acting within the scope of their duties for a foreign sovereign nation.
