WASHINGTON — In more than a dozen classified rulings, the nation’s surveillance court has created a secret body of law giving the National Security Agency the power to amass vast collections of data on Americans while pursuing not only terrorism suspects, but also people possibly involved in nuclear proliferation, espionage and cyberattacks, officials say.
The rulings, some nearly 100 pages long, reveal that the court has taken on a much more expansive role by regularly assessing broad constitutional questions and establishing important judicial precedents, with almost no public scrutiny, according to current and former officials familiar with the court’s classified decisions.
The 11-member Foreign Intelligence Surveillance Court, known as the FISA court, was once mostly focused on approving case-by-case wiretapping orders. But since major changes in legislation and greater judicial oversight of intelligence operations were instituted six years ago, it has quietly become almost a parallel Supreme Court, serving as the ultimate arbiter on surveillance issues and delivering opinions that will most likely shape intelligence practices for years to come, the officials said."
From the Washington Post:
"Secret Court's Redefinition of 'Relevant' Empowered Vast NSA Data-Gathering
The National Security Agency's ability to gather phone data on millions of Americans hinges on a secret court ruling that redefined a single word: "relevant."
This change—which specifically enabled the surveillance recently revealed by former NSA contractor Edward Snowden—was made by the secret Foreign Intelligence Surveillance Court, a group of judges responsible for making decisions about government surveillance in national-security cases. In classified orders starting in the mid-2000s, the court accepted that "relevant" could be broadened to permit an entire database of records on millions of people, in contrast to a more conservative interpretation widely applied in criminal cases, in which only some of those records would likely be allowed, according to people familiar with the ruling.
In interviews with The Wall Street Journal, current and former administration and congressional officials are shedding new light on the history of the NSA program and the secret legal theory underpinning it. The court's interpretation of the word enabled the government, under the Patriot Act, to collect the phone records of the majority of Americans, including phone numbers people dialed and where they were calling from, as part of a continuing investigation into international terrorism.
"Relevant" has long been a broad standard, but the way the court is interpreting it, to mean, in effect, "everything," is new, says Mark Eckenwiler, a senior counsel at Perkins Coie LLP who, until December, was the Justice Department's primary authority on federal criminal surveillance law."
