The Supreme Court is preventing survivors of a 1997 terrorist attack from seizing Persian artifacts at a Chicago museum to help pay a $71.5 million default judgment against Iran.

The court ruled 8-0 Wednesday against U.S. victims of a Jerusalem suicide bombing. They want to lay claim to artifacts that were loaned by Iran to the University of Chicago's Oriental Institute more than 80 years ago.

Justice Sonia Sotomayor wrote for the court that a provision of the Foreign Sovereign Immunities Act does not support the victims' case. That federal law generally protects foreign countries' property in the U.S. but makes exceptions when countries provide support to extremist groups.


The victims, who were wounded in the attack or are close relatives of the wounded, argued that Iran provided training and support to Hamas, which carried out the attack. Iran has refused to pay the court judgment.

The federal appeals court in Chicago had earlier ruled against the victims. The Supreme Court affirmed that ruling Wednesday.

The artifacts in question are 30,000 clay tablets and fragments containing ancient writings known as the Persepolis Collection. University archeologists uncovered the artifacts during excavation of the old city of Persepolis in the 1930s. The collection has been on loan to the university's Oriental Institute since 1937 for research, translation and cataloging.
