This amendment would lighten the burden of proof on victims of terrorism by creating a presumption of causation of damage. The amendment would establish that the defendant is presumed to be liable if it supported a listed entity that caused or contributed to the loss or damage, subject to the cause of action. The presumption could be refuted if the defendant proved that he or she did not cause or contribute to the loss or damage in question.
