The government has told a federal appeals court that a suit by an F.B.I. translator who was fired after accusing the bureau of ineptitude should not be allowed to proceed because it would cause significant damage to the national security and foreign policy of the United States." The case has become a lightning rod for critics who contend that the bureau retaliated against Ms. Edmonds and other whistle-blowers who have sought to expose management problems related to the antiterrorism campaign. The suit was dismissed in July after Attorney General John Ashcroft invoked a rarely used power and declared the case as falling under "state secret" privilege. The Justice Department retroactively classified a 2002 Congressional briefing about the case and some related letters from lawmakers, but this week it decided to permit the information to be released. The inspector general of the department concluded last month that the F.B.I. had failed to aggressively investigate Ms. Edmonds's accusations of espionage and fired her in large part for raising them. In a report that the department sought for months to keep classified, the inspector general issued a sharp rebuke to the bureau over its handling of Ms. Edmonds's accusations.
