Whether or not former Israeli spy Jonathan Pollard is still a man who knows too much cannot be considered in his effort to loosen the terms of his parole, a federal appellate judge said.

Pollard served 28 years in prison for a conspiracy to deliver national defense information to a foreign government. Following his release, he challenged restrictions imposed by the U.S. Parole Commission that he wear a GPS tracking device and that his probation officer can search his computer without warning. Last year, Southern District Judge Katherine Forrest upheld the commission's ruling.

In oral arguments Wednesday on Forrest's decision before the U.S. Court of Appeals for the Second Circuit, Eliot Lauer of Curtis, Mallet-Prevost, Colt & Mosle said the commission's ruling was based on the fact that Pollard may still remember confidential information.
