Congressional Budget Office Cost Estimate: S. 1894: Justice Against Sponsors of Terrorism Act [open pdf - 19KB]
"S. [Senate bill] 1894 would narrow the immunity of foreign states and their employees or agents against lawsuits from victims of terrorist acts, grant U.S. district courts jurisdiction over certain terrorism-related cases, and extend the statute of limitations for civil actions pertaining to terrorist acts. CBO [Congressional Budget Office] estimates that implementing S. 1894 would have no significant effect on the federal budget. Enacting S. 1894 could increase revenues; therefore, pay-as-you-go procedures apply. However, CBO estimates that any effects would not be significant in any year. Enacting the bill would not affect direct spending. Under the bill, it is possible that district courts would hear additional terrorism-related cases. The Departments of Justice and State often review such cases and issue recommendations to those courts. However, based on information from both agencies, CBO estimates that no additional personnel would be required to implement the bill and thus, that the bill would have insignificant discretionary costs over the 2013-2017 period."
