How a Court Secretly Evolved, Extending U.S. Spies' Reach
By CHARLIE SAVAGE and LAURA POITRAS
WASHINGTON -- Ten months after the Sept. 11 attacks, the nation's surveillance court delivered a ruling that intelligence officials consider a milestone in the secret history of American spying and privacy law. Called the "Raw Take" order -- classified docket No. 02-431 -- it weakened restrictions on sharing private information about Americans, according to documents and interviews.
The administration of President George W. Bush, intent on not overlooking clues about Al Qaeda, had sought the July 22, 2002, order. It is one of several still-classified rulings by the Foreign Intelligence Surveillance Court described in documents provided by Edward J. Snowden, the former National Security Agency contractor.
Previously, with narrow exceptions, an intelligence agency was permitted to disseminate information gathered from court-approved wiretaps only after deleting irrelevant private details and masking the names of innocent Americans who came into contact with a terrorism suspect. The Raw Take order significantly changed that system, documents show, allowing counterterrorism analysts at the N.S.A., the F.B.I. and the C.I.A. to share unfiltered personal information.
The leaked documents that refer to the rulings, including one called the "Large Content FISA" order and several more recent expansions of powers on sharing information, add new details to the emerging public understanding of a secret body of law that the court has developed since 2001. The files help explain how the court evolved from its original task -- approving wiretap requests -- to engaging in complex analysis of the law to justify activities like the bulk collection of data about Americans' emails and phone calls.
"These latest disclosures are important," said Steven Aftergood, the director of the Project on Government Secrecy at the Federation of American Scientists. "They indicate how the contours of the law secretly changed, and they represent the transformation of the Foreign Intelligence Surveillance Court into an interpreter of law and not simply an adjudicator of surveillance applications."
The Raw Take order appears to have been the first substantial demonstration of the court's willingness after Sept. 11 to reinterpret the law to expand government powers. N.S.A. officials included it as one of three court rulings on an internal timeline of key developments  in surveillance law from 1972 to 2010, deeming it a historic event alongside once-secret 2004 and 2006 rulings on bulk email and call data.
A half-dozen current and former officials defended the order as lawful and reasonable, saying it allowed the government to best use its experts on Al Qaeda -- wherever they worked -- to find nuggets of intelligence hidden in hours of phone calls or volumes of emails. They also noted that the agencies receiving the data must still apply privacy protections after evaluating Americans' information. An N.S.A. spokeswoman declined to comment about the ruling.
Still, Marc Rotenberg, the executive director of the Electronic Privacy Information Center, argued that the easing of privacy protections mandated by the Foreign Intelligence Surveillance Act of 1978 increased the risk of abuse and should not be a secret.
"The framers of FISA intended to narrowly restrict the ability of the government to disseminate this information because it has a very low standard enabling access to communications," he said. "If the FISA court removed those safeguards, it obviously raises questions about compliance with the intent of the act."
The number of Americans whose unfiltered personal information has been shared among agencies is not clear. Since the Sept. 11 attacks, the court has approved  about 1,800 FISA orders each year authorizing wiretaps or physical searches -- which can involve planting bugs in homes or offices, or copying hard drives -- inside the United States. But the government does not disclose how many people had their private conversations monitored as a result.
Other Americans whose international phone calls and emails were swept up in the N.S.A.'s warrantless wiretapping program after it was legalized in 2007 might have increased those numbers. After Congress amended the surveillance act to authorize the program, the court allowed raw sharing of personal information from it, too, according to leaked and declassified  documents.
The new disclosures come amid a debate over whether the surveillance court, which hears arguments only from the Justice Department, should be restructured for its evolving role. Proposals include overhauling how judges are selected to serve on it  and creating a public advocate  to provide adversarial arguments when the government offers complex legal analysis for expanding its powers.
The Bush administration sought the Raw Take order as it was trying to lower various bureaucratic barriers that impeded counterterrorism specialists across the government from working together.
Timothy Edgar, a Brown University visiting professor who worked at the Office of the Director of National Intelligence and at the White House from 2006 to 2013, said that after the Sept. 11 attacks "there was a big movement to make sure sharing took place early on and at a tactical level."
"Without the ability to have a small group of people that would be able to share intelligence at an earlier stage, at a raw stage," he added, "it was hard to cooperate at a more technical level."
Some efforts took place in public. In May 2002,  the surveillance court rejected a request to dismantle a "wall" that inhibited criminal prosecutors from working closely with intelligence investigators using FISA surveillance; that fall, a review court overturned the ruling.  Meanwhile, the administration was also pushing in private to get around obstacles to sharing information among intelligence agencies.
Congress had enacted FISA after revelations about decades of abuses of surveillance undertaken in the name of national security -- like the F.B.I.'s taping  of the Rev. Dr. Martin Luther King Jr.'s extramarital affairs and its sharing of the information with the Kennedy White House. The law required agencies to "minimize" private information about Americans -- deleting data that is irrelevant for intelligence purposes before providing it to others.
Exceptions had been narrow, like when an agency needed decoding or translating help from a counterpart. The Justice Department's 2002 motion -- formally called "In Re Electronic Surveillance and Physical Search of International Terrorist Groups, Their Agents, and Related Targets" -- argued that the court could interpret that exception more permissively.
People familiar with the request said it cited passages from a 1978 report  by the House Intelligence Committee that explained what lawmakers intended the original FISA bill to mean.
One section says that when information has not yet been examined and another agency is going to perform that task, minimization requirements are not yet in effect. Another explains that lawmakers intended that "a significant degree of latitude be given in counterintelligence and counterterrorism cases" regarding the retention or sharing of information "between and among counterintelligence components of the government."
Justice Department officials argued that those passages showed that it would be consistent with congressional intent to allow wider sharing of unevaluated, unminimized information among analysts at the N.S.A., the F.B.I. and the C.I.A. The court agreed, granting the order.
Current and former officials said only trained analysts with a need to see the raw information may access it. Still, Jameel Jaffer, a lawyer for the American Civil Liberties Union, noted that the government had cited stringent minimization rules to justify FISA surveillance as complying with the Constitution.
"It seems that at the same time the government has been touting the minimization requirements to the public, it's been trying behind closed doors to weaken those requirements," he said.
The newly disclosed documents also refer to a decision by the court called Large Content FISA, a term that has not been publicly revealed before. Several current and former officials, speaking on the condition of anonymity, said Large Content FISA referred to sweeping but short-lived orders issued on Jan. 10, 2007, that authorized the Bush administration to continue its warrantless wiretapping program.
The Bush administration had sought a ruling to put the program, which had been exposed by The New York Times,  on a firmer legal footing. Attorney General Alberto R. Gonzales disclosed  a week after the decision that a judge had issued "innovative" and "complex" orders bringing the program under the surveillance court's authority. But when they came up for renewal that April, another surveillance court judge balked and began requiring cumbersome paperwork, prompting the administration to seek a legislative solution, an intelligence official later explained. 
The documents do not explicitly say the Large Content FISA orders were the January 2007 decisions but are consistent with that explanation.
Two classification guides say that the N.S.A. used the orders  during a transition  to the enactment of the Protect America Act, an August 2007 law in which Congress legalized the program. It was replaced with the FISA Amendments Act in 2008.
The government has never provided details about the court's reasoning in pronouncing the program lawful. But the orders are also mentioned in a classified draft of an N.S.A. inspector general report  that Mr. Snowden disclosed, which calls them "Foreign Content" and "Domestic Content" orders. The report cites a legal theory that reinterpreted a key word in the original FISA -- the "facility" against which the court may authorize spying because a terrorism suspect is using it.
Facilities had meant phone numbers or email addresses, but a judge accepted an argument that they could instead be the gateways connecting the American communications network to the world, because Qaeda militants were probably among the countless people using those switches. Privacy protections would be applied afterward, the report said.
Asked about Large Content FISA orders, Vaneé Vines, an N.S.A. spokeswoman, said: "Since the enactment of the Protect America Act and the FISA Amendments Act, all collection activities that come within the scope of those statutes have been conducted pursuant to those statutes."
The Raw Take order, back in 2002, also relaxed limits on sharing private information about Americans with foreign governments. The bar was higher for sharing with outsiders: Raw information was not provided, and even information deemed relevant about a terrorism issue required special approval.
Under procedures described in a 1984 report,  only the attorney general could authorize such dissemination. But on Aug. 20, 2002,  Attorney General John Ashcroft, citing the recent order, secretly issued new procedures allowing the N.S.A. to provide information to foreign governments without his clearance.
"If the proposed recipient(s) of the dissemination have a history of human rights abuses, that history should be considered in assessing the potential for economic injury, physical harm, or other restriction of movement, and whether the dissemination should be made," he wrote.
Access within the N.S.A. to raw FISA information was initially limited to its headquarters at Fort Meade, Md. But in 2006, the N.S.A. expanded sharing to specialists at its code-breaking centers in Hawaii, Texas and Georgia. Only those trained would obtain access, but a review demonstrated that wider sharing had already increased risks. A document  noted that the agency was mixing two types of FISA information, each subject to different court-imposed rules, along with other records, and "it is possible that there are already FISA violations resulting from the way data has been stored in these databases."
The sharing of raw information continued to expand after the enactment of the FISA Amendments Act. On Sept. 4, 2008, the court issued an opinion, which remains secret but was cited in another opinion that has been declassified,  approving minimization rules  for the new law. A video explaining the new rules to N.S.A. employees noted that "C.I.A. and F.B.I. can have access to unminimized data in many circumstances."
A footnote in a now-declassified October 2011 opinion  shows that the N.S.A. did not share one category of raw data: emails intercepted at network switches, as opposed to those gathered from providers like Yahoo. For technical reasons, the switch tactic intercepts tens of thousands of purely domestic and unrelated emails annually.
Around early 2012, the court approved the expansion of sharing to a fourth agency, the National Counterterrorism Center, a clearinghouse for terrorism threat information. A May 2012 document says the "fact that NCTC is in receipt of raw or unminimized FISA information" is classified at a level reserved for data whose disclosure would "cause serious damage" to national security. 
Intelligence officials, when pressed, offered no rationale for why public knowledge of the court's interpretation of legal limits on sharing information met that standard.
