Revealed: the top secret rules that allow NSA to use US data without a warrant

Fisa court submissions show broad scope of procedures governing NSA's surveillance of Americans' communication

Top secret documents submitted to the court that oversees surveillanceby US intelligence agencies show the judges have signed off on broad orders which allow the NSA to make use of information "inadvertently" collected from domestic US communications without a warrant.

The Guardian is publishing in full two documents submitted to the secret Foreign Intelligence Surveillance Court (known as the Fisa court), signed by Attorney General Eric Holder and stamped 29 July 2009. They detail the procedures the NSA is required to follow to target "non-US persons" under its foreign intelligence powers and what the agency does to minimize data collected on US citizens and residents in the course of that surveillance.

The documents show that even under authorities governing the collection of foreign intelligence from foreign targets, US communications can still be collected, retained and used.

The procedures cover only part of the NSA's surveillance of domestic US communications. The bulk collection of domestic call records, as first revealed by the Guardian earlier this month, takes place under rolling court orders issued on the basis of a legal interpretation of a different authority, section 215 of the Patriot Act.

The Fisa court's oversight role has been referenced many times by Barack Obama and senior intelligence officials as they have sought to reassure the public about surveillance, but the procedures approved by the court have never before been publicly disclosed.

The top secret documents published today detail the circumstances in which data collected on US persons under the foreign intelligence authority must be destroyed, extensive steps analysts must take to try to check targets are outside the US, and reveals how US call records are used to help remove US citizens and residents from data collection.

However, alongside those provisions, the Fisa court-approved policies allow the NSA to:

• Keep data that could potentially contain details of US persons for up to five years;

• Retain and make use of "inadvertently acquired" domestic communications if they contain usable intelligence, information on criminal activity, threat of harm to people or property, are encrypted, or are believed to contain any information relevant to cybersecurity;

• Preserve "foreign intelligence information" contained within attorney-client communications;

• Access the content of communications gathered from "U.S. based machine[s]" or phone numbers in order to establish if targets are located in the US, for the purposes of ceasing further surveillance.

The broad scope of the court orders, and the nature of the procedures set out in the documents, appear to clash with assurances from President Obama and senior intelligence officials that the NSA could not access Americans' call or email information without warrants.

The documents also show that discretion as to who is actually targeted under the NSA's foreign surveillance powers lies directly with its own analysts, without recourse to courts or superiors – though a percentage of targeting decisions are reviewed by internal audit teams on a regular basis.

Section 702 of the Fisa Amendments Act (FAA), which was renewed for five years last December, is the authority under which the NSA is allowed to collect large-scale data, including foreign communications and also communications between the US and other countries, provided the target is overseas.

FAA warrants are issued by the Fisa court for up to 12 months at a time, and authorise the collection of bulk information – some of which can include communications of US citizens, or people inside the US. To intentionally target either of those groups requires an individual warrant.

One-paragraph order

One such warrant seen by the Guardian shows that they do not contain detailed legal rulings or explanation. Instead, the one-paragraph order, signed by a Fisa court judge in 2010, declares that the procedures submitted by the attorney general on behalf of the NSA are consistent with US law and the fourth amendment.

Those procedures state that the "NSA determines whether a person is a non-United States person reasonably believed to be outside the United States in light of the totality of the circumstances based on the information available with respect to that person, including information concerning the communications facility or facilities used by that person".

It includes information that the NSA analyst uses to make this determination - including IP addresses, statements made by the potential target, and other information in the NSA databases, which can include public information and data collected by other agencies.

Where the NSA has no specific information on a person's location, analysts are free to presume they are overseas, the document continues.

-----The broad nature of the court's oversight role, and the discretion given to NSA analysts, sheds light on responses from the administration and internet companies to the Guardian's disclosure of the PRISM program. They have stated that the content of online communications is turned over to the NSA only pursuant to a court order. But except when a US citizen is specifically targeted, the court orders used by the NSA to obtain that information as part of Prism are these general FAA orders, not individualized warrants specific to any individual.

Once armed with these general orders, the NSA is empowered to compel telephone and internet companies to turn over to it the communications of any individual identified by the NSA. The Fisa court plays no role in the selection of those individuals, nor does it monitor who is selected by the NSA.

The NSA's ability to collect and retain the communications of people in the US, even without a warrant, has fuelled congressional demands for an estimate of how many Americans have been caught up in surveillance.

Two US senators, Ron Wyden and Mark Udall – both members of the Senate intelligence committee – have been seeking this information since 2011, but senior White House and intelligence officials have repeatedly insisted that the agency is unable to gather such statistics.
