Judges consider whether FBI violated free speech

NEW YORK (Reuters) - A panel of federal appeals court judges pushed a U.S. government lawyer on Wednesday to answer why FBI letters sent out to Internet service providers seeking information should remain secret.

A panel of three judges from the U.S. Second Circuit Court of Appeals heard arguments on whether a provision of the Patriot Act, which requires people who are formally contacted by the Federal Bureau of Investigation for information to keep it a secret, is constitutional.

The American Civil Liberties Union filed suit in 2004 on behalf of an undisclosed Internet service provider against the U.S. government challenging the so-called National Security Letters (NSL) as well as gag orders placed on the recipients.
