FALLS CHURCH, Va. (AP) — A divided federal appeals court has upheld the dismissal of an ACLU lawsuit challenging a portion of the National Security Agency’s warrantless surveillance of Americans’ international email and phone communications. The 4th U.S. Circuit Court of Appeals ruled Wednesday that the lawsuit must be dismissed after the government invoked the “state secrets privilege” — meaning that a full exploration of the issue in a court of law would damage national security. In the lawsuit the Wikimedia Foundation, which runs Wikipedia, said that the National Security Agency’s “Upstream” surveillance program necessarily captures some of its international communications and is a violation of free-speech rights and its Fourth Amendment rights against unreasonable search and seizure.
