The U.S. Court of Appeals for the Second Circuit on Friday refused to overturn sanctions against the Jordan-based Arab Bank, which is being sued by thousands of plaintiffs for allegedly providing services to terrorist groups and handling accounts that those groups used to pay the families of suicide bombers.

In 2010, Eastern District of New York Judge Nina Gershon ordered Arab Bank to turn over records requested by the plaintiffs or face sanctions. The bank argued it could not turn over the records because of bank secrecy laws. Gershon said that if it did not, it would be sanctioned by allowing the jury to infer that it had aided Hamas and other terrorist groups.
