Central Intelligence Agency v. Sims, 471 U.S. 159 (1985), was a decision of the U.S. Supreme Court. In the case, the court ruled that[1] the Central Intelligence Agency was permitted to withhold the identities and institutional affiliations of scientific researchers who worked on Project MKUltra. The project was conducted by the CIA, and focused on human experimentation.[2] The case held that the Central Intelligence Agency could, in fact, classify the researchers as intelligence sources, and thus withhold their names from disclosure to the public, in addition to their institutional affiliations.[3] The decision by the Supreme Court reversed, in part, the decision made prior by the lower district and appeals courts on the case.[3]
Background
From 1953 to 1973, the Central Intelligence Agency operated Project MKUltra, subjecting U.S and Canadian citizens to experimentation without their prior knowledge or informed consent.[4][5] The project involved the use of LSD on American and Canadian citizens, as well as experimentation with further drugs such as heroin and morphine, among others.[6] The CIA had, during the course of the project, utilized the assistance of 185 individual researchers spanning across around 80 institutions.[7]
History of the case
The plaintiffs were John Cary Sims and Sidney M. Wolfe, an attorney and director of Public Citizen respectively.[8] The two plaintiffs originally filed a Freedom of Information Act request against the CIA in the public interest, based upon the discovery of new documents by the CIA in relation to the MKUltra project in 1977 relating to the names of researchers and facilities, which were originally presumed to be destroyed in 1973 prior to investigations into the project.[9] They requested information about both the grant proposals and contracts awarded by the CIA in relation to the MKUltra project, and the names and institutional affiliations for the researchers who worked on the project, as well as the names of research facilities.[10][11] The CIA granted the request for information about grant proposals and contracts,[10] as well as the request for names of most of the research facilities, though declined to provide information in relation to the names and affiliations of researchers, and retained knowledge of 21 other research facilities used in the project.[11] Based upon the denial of the remainder of the information request by the CIA, both Sims and Wolfe filed suit against the Central Intelligence Agency.[12]
The plaintiffs sued the Central Intelligence Agency in the United States District Court for the District of Columbia. The District Court ruled in favor of the plaintiffs originally, and held that the names of the researchers involved in the MKUltra project did not constitute "intelligence sources" under the law, and thus could not be withheld from Freedom of Information Act requests by the public.[13] The Central Intelligence Agency challenged this ruling to the United States Court of Appeals for the District of Columbia Circuit, which resulted in a remand of the judgement of the District Court, with the Court of Appeals determining the District Court did not have a sufficient definition for an intelligence source.[14] The District Court reviewed evidence submitted regarding the applicability of the Court of Appeals' definition of an intelligence source on remand, and determined that researchers who had previously received a guarantee of confidentiality were exempt from disclosure, but that the other remaining researchers were not intelligence sources, as the Central Intelligence Agency had not promised them confidentiality.[15] This decision was again appealed to the Court of Appeals, who remanded the case again to the District Court, determining that the District Court had erred in using the lack of a promise of confidentiality as a basis of determining the applicability of the term of intelligence source.[16] The Central Intelligence Agency then appealed the decision to the Supreme Court.[16]
Case law
Under the Freedom of Information Act, any citizen can make a request of the government for production of records held in an agency's possession, with some exceptions for records deemed to not be releasable under the Act.[17] The third exemption specified in the Act, however, authorizes the refusal to disclose information that is classified subject to a relevant statutory basis.[18] Both the National Security Act of 1947 and the Central Intelligence Agency Act were used to justify the Central Intelligence Agency's refusal to disclose records. The CIA Act, however, was largely intended by the drafters of the act to apply to the CIA acting in foreign countries, not domestically within the United States.[19]
The case, from its inception, involved primarily the application of the National Security Act of 1947. This act assigned the responsibility for the protection of "intelligence sources and methods" to the Director of the CIA.[20] The act did not make an explicit definition of an intelligence source,[21] and the definition of an intelligence source has generally been subject to the interpretation of the courts.[22] This left the Director of the CIA to produce an interpretation of the applicability of the term to the researchers working on the project, of which the district court reasoned led to an "overbroad interpretation".[23]
Decision of the court

The decision of the court was unanimously in favor of the Central Intelligence Agency, with Chief Justice Warren E. Burger delivering the opinion of the court, joined by Justices White, Blackmun, Powell, Rehnquist, Stevens, and O'Connor. The Court thus concluded that someone who is an intelligence source "provides, or is engaged to provide, information the agency needs to fulfill its statutory obligations", which fit the researchers at issue in the case.[24] The majority opinion both considered the National Security Act and established a definition that the Court used to determine the validity of an intelligence source in being withheld from a FOIA request.[25] The majority opinion found that the National Security Act did permit the withholding of information under FOIA's exemption 3, because the Director of the CIA was responsible for the protection of intelligence sources. However, the lack of a working definition within the National Security Act led to a necessity of the majority to furnish lower courts and the public with a new definition, as the majority found the definition used by the Court of Appeals to be too narrow. The Court thus established that an intelligence source "provides, or is engaged to provide, information the Agency needs to fulfill its statutory obligations...related to the Agency's intelligence function".[26] Throughout the majority opinion, Chief Justice Burger repeatedly referred to showing deference to the withholding discretion of the CIA as an important matter, and rejected the suggestion that judges have the ability to judicially review the withholding decisions made by the Director of the CIA on a de novo basis.[27]
The two remaining justices were Justices Marshall and Brennan, of whom Justice Marshall issued a concurring opinion, which Justice Brennan joined. The main point of contention in the concurrence was presented regarding the Court's acceptance of the government's definition of an "intelligence source" for the purposes of the National Security Act. While the concurrence differs in opinion from the majority opinion on the matter of acceptance of the government's interpretation, it remains aligned with the majority opinion in the view of the outcome of the case.[3] While Marshall's concurring opinion agreed with the outcome, he argued that the overly broad interpretation of an intelligence source was in excess of the meaning or history of that intended by Congress. Marshall highlighted his agreement with the Court in determining that the Court of Appeals' definition was narrow to the point of disclosing far more than material that should be disclosed. However, he argued that the majority opinion went too far in the other extreme, instead swinging to a definition that would permit the Central Intelligence Agency to withhold records that would be entirely unrelated to the requirements of secrecy.[28] Marshall additionally critiqued the CIA's usage of exemption 3, rather than a usage of exemption 1 of the Freedom of Information Act. The legal difference between the two exemptions is that exemption 1 provides for the refusal to disclose information classified by an executive order. The key practical difference within the two exemptions, however, as Marshall noted, was that the CIA was able to evade judicial review to a point that would not have occurred in the event the agency had utilized exemption 1, which, while Marshall agreed that it would have allowed for the same outcome, he argued would keep in place necessary limits on the abilities of the CIA to determine secrecy of information without judicial oversight.[29]
Legal reaction and analysis
Legal scholars critiqued the majority opinion, largely arguing that the Sims decision amounted to a new limitation on the abilities of judicial review of lower courts.[30] Michael Hughes, in the Catholic University Law Review, argued that the majority had cited and thus focused on the legislative record of the National Security Act, and highlighted that the majority of such legislative debate had focused more on the overall creation of an intelligence agency. However, the legislative history, as Hughes highlights, did not reflect any significant opinions of the legislators in regards to the Freedom of Information Act exemption.[31] Hughes criticized the Court's decision in failing to determine the overall role of the judiciary in determining whether material should be disclosed, and instead adhering to the Central Intelligence Agency's discretion in determining which material was suitable for public release upon the receipt of a FOIA request.[32]
In analysis of the decision itself and the impact on cases that followed the Sims decision, Martin Halstuk, writing in the Hastings Communications and Entertainment Journal, found that while the Court's majority decision provided a large amount of discretion to the Director of the Central Intelligence Agency to determine the withholding of documents and records, lower courts had also expressed some disagreement with this decision in later cases.[33] Halstuk highlights that the decision resulted in multiple notable decisions where a court is constrained in the context of withholding decisions by the CIA. Halstuk, reviewing the twenty years following the Court's determination in Sims, argues that lower courts have been affirmed on review in a multitude of instances when they cite the Sims decision as the rationale for denying contestations of refusals by the CIA to release documents when sought by outside parties, whether outside citizens or corporations in general.[34]
