Court cases before the Foreign Intelligence Surveillance Court — the court that reviews requests by the NSA to wiretap suspected terrorists’ communications — are generally classified. But Judge F. Dennis Saylor IV of the Foreign Intelligence Surveillance Court ordered the government to review the court’s opinions on the meaning, scope, and constitutionality of Section 215 of the Patriot Act, which authorizes the government to obtain “any tangible things” relevant to foreign-intelligence or terrorism investigations.
