U.S. Circuit Judge Myrna Pérez made her panel debut Monday on the U.S. Court of Appeals for the Second Circuit, as judges puzzled over whether to revive an unusual suit seeking to hold J.P. Morgan Chase & Co. accountable for a predecessor’s alleged role in the Iranian hostage crisis.

The lawsuit, filed last year in the Southern District of New York by former hostages and their family members, claimed the company—and its former executive David Rockefeller—had “fomented the seizure of American hostages in Iran and then sabotaged the talks to free them” during the Carter administration, when the bank was known as Chase Manhattan Bank.
