A federal appeals court in New York has ruled that the once-secret National Security Agency program that is systematically collecting Americans’ phone records in bulk is illegal. Overturning a 2013 ruling, a three-judge panel for the US Court of Appeals for the Second Circuit held that a provision of the U.S.A. Patriot Act, known as Section 215, cannot be legitimately interpreted to allow the bulk collection of domestic calling records. The judges did not, however, halt the program, but urged Congress to take action.
