The grandson of a murdered Iranian general won a reprieve Tuesday in a Washington appeals court, which found his suit against Iran is entitled to additional hearings. The U.S. Court of Appeals for the D.C. Circuit overturned the dismissal of the suit and told the lower court to take a look at French law.

Gen. Gholam Ali Oveissi was assassinated on a crowded street in Paris in 1984. Members of Hezbollah claimed responsibility for the shooting. Two decades later his grandson, Amir Reza Oveissi, sued the Iranian government and the Iranian Ministry of Information and Security for an alleged state-sponsored terrorist act. The grandson’s suit, filed in June 2003 in U.S. District Court for the District of Columbia, alleged intentional infliction of emotional distress and wrongful death.
