The U.S. Supreme Court declined to hear a case attempting to curtail the U.S. National Surveillance Agency's online communications surveillance program, Cyberscoop reports. Advocacy groups sought to raise the case to the highest court after the U.S. Court of Appeals for the Fourth Circuit upheld the NSA's practices. The NSA's program allows for warrantless collection of online communications data as it moves through telecommunications systems. The program is authorized under Section 702 of the Foreign Intelligence Surveillance Act, which is up for renewal.
