Congressional Budget Office Cost Estimate: S. 2134, Terrorism Victim's Access to Compensation Act of 2002 [open pdf - 19KB]
From the Summary: "S. 2134 would give victims of state-sponsored terrorism access to the blocked assets of those states to satisfy judgments for compensatory damages. The blocked assets most immediately affected by S. 2134 are former diplomatic properties of the government of Iran which are covered by the Vienna Conventions on Diplomatic Relations and Consular Relations (the Vienna Conventions). According to the Department of State, attaching these properties to satisfy judgments against Iran would likely lead to a claim by Iran against the United States in an international tribunal and the payment of damages to Iran. In addition, the bill would authorize the payment of a few specific judgments against Iran from existing funds. CBO [Congressional Budget Office] estimates that enacting the bill would cost $22 million in 2003 and $29 million in 2004. Because S. 2134 would affect direct spending, pay-as-you-go procedures would apply."
