The Wall Street Journal reports the legality of the National Security Agency's bulk collection of phone records will be tested this week before a panel of federal judges, the first appeals court to address the controversial program amid efforts by Congress to rein it in. The hearing scheduled for Tuesday at the Second U.S. Circuit Court of Appeals in New York stems from a lawsuit filed by the American Civil Liberties Union and its New York affiliate. It was filed in June 2013, days after the program was revealed in news reports, which relied largely on documents provided by former NSA contractor Edward Snowden. The groups argue that the bulk collection of phone metadata—including the time, duration and dialing and receiving numbers—violates privacy rights, as well as federal law. In the lawsuit, the group said the NSA program was "akin to snatching every American's address book—with annotations detailing whom we spoke to, when we talked, for how long, and from where." The Justice Department has argued callers have no privacy interest in their phone metadata, which they willingly provide to their telecommunication companies every time they make a call.
