Court rebuked NSA on its use of phone data

2009 ruling says agency violated its own procedures

Documents released by Edward Snowden spurred the recent disclosures about the agency.

Documents released by Edward Snowden spurred the recent disclosures about the agency.

WASHINGTON — Intelligence officials released secret documents Tuesday showing that a judge reprimanded the National Security Agency in 2009 for violating its own procedures and misleading the nation’s intelligence court about how it used the telephone call logs it gathers in the hunt for terrorists.

It was the second case of a severe scolding of the spy agency by the Foreign Intelligence Surveillance Court to come to light since the disclosure of thousands of NSA documents by Edward J. Snowden, a former contractor, began this summer.

The newly disclosed violations involved the NSA program that has drawn perhaps the sharpest criticism from members of Congress and civil libertarians: the collection and storage for five years of information on virtually every US phone call. The agency uses orders from the intelligence court to compel phone companies to turn over records of numbers called and the time and duration of each call — the “metadata,” not the actual content of the calls.

Since Snowden disclosed the program, the agency has said that while it gathers data on billions of calls, it makes only a few hundred queries in the database each year, when it has “reasonable, articulable suspicion” that a telephone number is connected to terrorism.

But the new documents show that the agency also compares each day’s phone call data as it arrives with an “alert list” of thousands of domestic and foreign phone numbers that it has identified as possibly linked to terrorism.

The agency told the court that all the numbers on the alert list had met the legal standard of suspicion, but that was false. In fact, only about 10 percent of 17,800 phone numbers on the alert list in 2009 had met that test, officials said.

In a sharply worded March 2009 ruling, Judge Reggie B. Walton described the NSA’s failure to comply with rules set by the intelligence court, set limits on how it could use the data it had gathered, and accused the agency of repeatedly misinforming the judges.

“The government has compounded its noncompliance with the court’s orders by repeatedly submitting inaccurate descriptions of the alert list process” to the court, Walton wrote. “It has finally come to light that the FISC’s authorizations of this vast collection program have been premised on a flawed depiction of how the NSA uses” the phone call data.

A senior US intelligence official, briefing reporters before the documents’ release, admitted the sting of the court’s reprimand but said the problems came in a complex, highly technical program and were unintentional.

“There was nobody at NSA who really had a full understanding of how the program was operating at the time,” said the official, who spoke on the condition of anonymity.

The official noted that the agency itself discovered the problem, reported it to the court and to Congress, and worked out new procedures that the court approved.

In making public 14 documents on the website of the director of national intelligence, James R. Clapper Jr., the intelligence officials were acting in response to Freedom of Information Act lawsuits and a call from President Obama for greater transparency about intelligence programs. The lawsuits were filed by two advocacy groups, the Electronic Frontier Foundation and the American Civil Liberties Union.

“The documents only begin to uncover the abuses of the huge databases of information the NSA has of innocent Americans’ calling records,” said Mark M. Jaycox, a policy analyst at the Electronic Frontier Foundation. He said the agency’s explanation — that none of its workers fully understood the phone metadata program — showed “how much of a rogue agency the NSA has become.”

Walton’s ruling, originally classified as top secret, did not go that far. But he wrote that the privacy safeguards approved by the court “have been so frequently and systematically violated” that they “never functioned effectively.”

Senator Patrick J. Leahy of Vermont, chairman of the Senate Judiciary Committee, welcomed the release of the documents but said that they showed “systemic problems” and that the bulk collection of Americans’ phone records should be stopped.

Intelligence officials have expressed some willingness to adjust the program in response to complaints from Congress and the public, possibly by requiring the phone companies, rather than the NSA, to stockpile the call data. But they say that the program remains crucial in detecting terrorist plots and is now being run in line with the court’s rules.

A different intelligence court judge rebuked the NSA in 2011 for violations in another program and also complained of a pattern of misrepresentation. The 2011 opinion was released by intelligence officials last month.
