Northrop Grumman cannot be held liable for passing information on to immigration authorities about possible security problems with two participants in a special U.S. visa program, the 2nd U.S. Circuit Court of Appeals has ruled.

Even though the subcontractor being overseen by Northrop Grumman may have raised false concerns about the two visa participants, the circuit said that Northrop Grumman should be absolutely immune from state tort liability for forwarding the information to the former Immigration and Naturalization Service and the Department of State.
