A three-judge panel at the U.S. Court of Appeals in Washington, D.C. unanimously authorized a settlement between the federal government and the Dutch company Fokker Services B.V. accused of sanctions violations, overturning a district court ruling that had thrown out the deferred-prosecution agreement as too lenient.  Fokker, an aerospace company, had agreed to pay $21 million as part of an 18-month deferred prosectuion agreement to settle charges that it sold aircraft parts to Iranian military customers, as well as to customers in Burma and Sudan, in violation of U.S. law.
