The Supreme Court announced on its website that the status of the case "SOKOLOW, MARK, ET AL. V. PALESTINE LIBERATION ORG.," is now "certiorari denied."
The victims had sought to reinstate a $654 million dollar verdict against the PLO and Palestinian Authority that was thrown out by an appeals court in 2016.
The attacks occurred in Israel in 2002 and 2004, and the victims had filed the lawsuit under the Anti-Terrorism Act, which allows American victims of terrorist attacks overseas to seek compensation in US courts.
The victims believed they could bring the lawsuit in a US court because the Palestinians had offices in Washington, DC, but the appeals court disagreed.
