§3144 Operational Files of the National Security Agency

Title 50 › CHAPTER 44 — NATIONAL SECURITY › SUBCHAPTER V — PROTECTION OF OPERATIONAL FILES › § 3144

Last updated Sep 22, 2026|Official source

Summary

Lets the Director of the National Security Agency, working with the Director of National Intelligence, keep certain NSA "operational files" off the public records rules in section 552 of title 5 (the Freedom of Information Act). Operational files means two kinds of records: Signals Intelligence Directorate files that show how technical systems collect foreign intelligence, and Research Associate Directorate files that show how scientific or technical systems collect foreign intelligence. Files that only hold already-shared intelligence or that are in the NSA Archives are not counted as operational files. Even when these files are exempt, they still must be searched or reviewed in some cases. That includes when a U.S. citizen or lawful permanent resident asks for their own records, when a special activity is not itself exempt, or when specific oversight bodies investigate possible wrongdoing. Those oversight bodies include certain House and Senate intelligence and armed services committees, the Intelligence Oversight Board, the Department of Justice, the NSA’s general counsel and inspector general, the DoD inspector general, and the NSA Director’s office. Information copied from exempt files into non-exempt files must be handled normally, but copying does not remove the exemption from the original operational file. Declassifying parts of a file does not end the exemption. The exemption can only be changed by a law passed after November 24, 2003 that specifically says so. If someone claims the NSA wrongly withheld records, they can ask a court to review the claim under FOIA rules, but the law sets special rules: courts may review classified material in private; parties must use sworn written statements to show facts; the NSA can meet its burden with sworn filings that the exempt files likely contain the records; normal discovery is mostly barred; if the court finds the NSA withheld records improperly it can order the NSA to search the proper exempt files and release records as required. The NSA and DNI must review these exemptions at least every 10 years and consider whether records should be opened for historical or public interest reasons. A person may sue only to check that the 10-year review happened and that those criteria were considered.

(2)The inclusion of information from exempted operational files in files that are not exempted under subsection (a) shall not affect the exemption under subsection (a) of the originating operational files from search, review, publication, or disclosure.
(3)The declassification of some of the information contained in exempted operational files shall not affect the status of the operational file as being exempt from search, review, publication, or disclosure.
(4)Records from exempted operational files that have been disseminated to and referenced in files that are not exempted under subsection (a) and that have been returned to exempted operational files for sole retention shall be subject to search and review.
(e)Supersedure of other laws
The provisions of subsection (a) may not be superseded except by a provision of law that is enacted after November 24, 2003, and that specifically cites and repeals or modifies such provisions.
(f)Allegation; improper withholding of records; judicial review
(1)Except as provided in paragraph (2), whenever any person who has requested agency records under section 552 of title 5 alleges that the National Security Agency has withheld records improperly because of failure to comply with any provision of this section, judicial review shall be available under the terms set forth in section 552(a)(4)(B) of title 5.
(2)Judicial review shall not be available in the manner provided for under paragraph (1) as follows:

(B)The court shall determine, to the fullest extent practicable, the issues of fact based on sworn written submissions of the parties.
(C)When a complainant alleges that requested records are improperly withheld because of improper placement solely in exempted operational files, the complainant shall support such allegation with a sworn written submission based upon personal knowledge or otherwise admissible evidence.
(D)(i)When a complainant alleges that requested records were improperly withheld because of improper exemption of operational files, the National Security Agency shall meet its burden under section 552(a)(4)(B) of title 5 by demonstrating to the court by sworn written submission that exempted operational files likely to contain responsive records currently perform the functions set forth in subsection (b).
(ii)The court may not order the National Security Agency to review the content of any exempted operational file or files in order to make the demonstration required under clause (i), unless the complainant disputes the National Security Agency’s showing with a sworn written submission based on personal knowledge or otherwise admissible evidence.
(E)In proceedings under subparagraphs (C) and (D), the parties may not obtain discovery pursuant to rules 26 through 36 of the Federal Rules of Civil Procedure, except that requests for admissions may be made pursuant to rules 26 and 36.
(F)If the court finds under this subsection that the National Security Agency has improperly withheld requested records because of failure to comply with any provision of this subsection, the court shall order the Agency to search and review the appropriate exempted operational file or files for the requested records and make such records, or portions thereof, available in accordance with the provisions of section 552 of title 5, and such order shall be the exclusive remedy for failure to comply with this section (other than subsection (g)).

The Director of National Intelligence must approve any determination to remove such exemptions.
(2)The review required by paragraph (1) shall include consideration of the historical value or other public interest in the subject matter of a particular category of files or portions thereof and the potential for declassifying a significant part of the information contained therein.
(3)A complainant that alleges that the National Security Agency has improperly withheld records because of failure to comply with this subsection may seek judicial review in the district court of the United States of the district in which any of the parties reside, or in the District of Columbia. In such a proceeding, the court’s review shall be limited to determining the following:
(A)Whether the National Security Agency has conducted the review required by paragraph (1) before the expiration of the 10-year period beginning on November 24, 2003, or before the expiration of the 10-year period beginning on the date of the most recent review.
