Anti-Terrorism Act (ATA)

The Justice Against Sponsors of Terrorism Act (JASTA)

​Anti-Terrorism Act (ATA) / Justice Against Sponsors of Terrorism Act (JASTA)

​

The Anti-Terrorism Act (ATA), 18 U.S.C. § 2333, creates a federal civil cause of action allowing U.S. nationals—and their estates, survivors, or heirs—to recover treble damages, attorneys’ fees, and costs when they are injured “by reason of” an act of international terrorism. Originally enacted in 1992 and significantly strengthened by the Justice Against Sponsors of Terrorism Act (JASTA) in 2016, the ATA now expressly permits claims based on aiding-and-abetting and conspiracy liability. JASTA expanded the statute’s reach by allowing plaintiffs to hold secondary actors accountable when they knowingly provide substantial assistance to designated foreign terrorist organizations or engage in conduct that foreseeably furthers acts of terrorism.

​

Herischi Law has developed a sophisticated practice applying the ATA and JASTA to complex cases involving state-directed or state-supported terrorism. We carefully analyze the elements of “international terrorism,” causation, and secondary liability, often drawing on evidence of material support, financing, training, or operational direction provided by foreign governments or their agents. Our litigation frequently addresses missile and drone strikes, assassinations, proxy attacks, and other forms of violence directed against civilians, opposition groups, and U.S. interests abroad.

​

We bring a strategic, multi-layered approach to these cases, combining factual investigation, expert testimony, and legal analysis to build compelling narratives that resonate with judges and juries. By pursuing treble damages and full recovery of costs, we aim not only to compensate victims but also to impose a meaningful financial deterrent on sponsors of terrorism. Our work under the ATA/JASTA often intersects with sanctions regimes and other human rights statutes, creating powerful synergies that maximize client outcomes.

Clients harmed by international terrorism—whether through direct injury, the loss of a loved one, or severe emotional distress—turn to us because we offer aggressive, results-oriented representation that treats their claims with the urgency and thoroughness they require. We guide clients through the entire process, from preliminary investigation to final judgment, while providing clear communication and personalized support at every step. If you or your family has suffered because of terrorism or state-sponsored violence, we are prepared to fight for the full measure of compensation and accountability available under these statutes.
