The State Secrets Privilege: National Security 
April 28, 2022 
Information in Civil Litigation 
Jennifer K. Elsea 
Over time, the Supreme Court of the United States has developed the common law doctrine 
Legislative Attorney 
known as the “state secrets privilege,” which protects sensitive national security information 
  
from being disclosed in civil litigation. In particular, there are two seminal cases that discuss the 
privilege’s applicability. 
Edward C. Liu 
First, in the 1876 case of 
Totten v. United States,
 the Court held that the 
Legislative Attorney 
judiciary lacks jurisdiction to hear a suit in which the underlying subject matter is a state secret if 
  
the suit “would inevitably lead to the disclosure of matters which the law itself regards as 
confidential.” Second, based on the Court’s 1953 decision in 
Reynolds v. United States, the Court 
 
has permitted the government to invoke the state secrets privilege more narrowly to protect only 
certain pieces of sensitive evidence if there is a reasonable danger that disclosure during litigation “will expose military 
matters which, in the interest of national security, should not be divulged.”  
A frequent question in litigation involving the state secrets doctrine is how far courts should scrutinize the government’s 
assertions of the risk of disclosure once the privilege has been formally invoked. 
Reynolds recognized that it is the role of the 
judiciary to evaluate the validity of a claim of privilege, but it declined to require courts to automatically compel inspection 
of the underlying information. As the Court noted, “too much judicial inquiry into the claim of privilege would force 
disclosure of the thing the privilege was meant to protect, while a complete abandonment of judicial control would lead to 
intolerable abuses.” Therefore, although the privilege requires some deference to the executive branch, an independent 
evaluation of the claim of privilege is necessary so as not to abdicate control over evidence “to the caprice of executive 
officers.” In light of this dilemma, the Court charted a middle course, employing a “formula of compromise” to balance the 
competing interests of oversight by the judiciary, the plaintiffs’ need for the evidence, and national security interests.  
During its October 2021 Term, the Supreme Court decided two cases involving the state secrets privilege. In 
United States v. 
Zubaydah, the Court determined that a court cannot declare that classified information apparently in the public domain is not 
subject to the state secrets privilege when the United States has not officially confirmed or denied such information. In 
Federal Bureau of Investigation v. Fazaga, the Court decided that certain Foreign Intelligence Surveillance Act of 1978 
(FISA) provisions, which specifically require courts to review the underlying classified FISA applications and information to 
determine the lawfulness of surveillance, do not displace the traditional 
Reynolds privilege that protects information that 
would harm national security if disclosed.  
In addition to discussing these two recent decisions, this report presents an overview of the protections afforded by the state 
secrets privilege, a discussion of some of the many unresolved issues associated with the privilege, and a selection of high-
profile examples of how the privilege has been applied. Some examples of areas in which the government has invoked the 
privilege include electronic surveillance, government contract cases, employment cases, targeted killings, the terrorist 
screening database, extraordinary rendition, and a case involving alleged Saudi liability for the terrorist attacks of September 
11, 2001. The report concludes by describing some considerations for Congress.

The State Secrets Privilege: National Security Information in Civil Litigation 
 
he Supreme Court of the United States has long recognized a common law government 
privilege against the disclosure of state and military secrets in civil litigation known as the 
T “state secrets privilege.”1 The United States has invoked this privilege in two broad 
categories of cases. First, beginning with the 1876 case of 
Totten v. United States,
 the government 
has argued that if the underlying subject matter of a lawsuit is a state secret, then the courts must 
dismiss the action for lack of jurisdiction.2 In the second category of cases, the government has 
invoked the state secrets privilege to bar the disclosure or introduction of certain pieces of 
national security information into evidence based on the Court’s 1953 decision in 
Reynolds v. 
United States.3  
In its October 2021 Term, the Supreme Court considered two cases touching on different aspects 
of the state secrets doctrine. The first case, 
United States v. Zubaydah, asked whether a court can 
compel the depositions of former Central Intelligence Agency (CIA) contractors over the 
government’s assertion of the state secrets privilege.4 In the second case, 
Federal Bureau of 
Investigation v. Fazaga, the Court considered whether the Foreign Intelligence Surveillance Act 
of 1978 (FISA) displaced the common law state secrets privilege.5 In both cases, which are 
discussed in more detail below, the Supreme Court upheld the government’s assertion of the 
privilege. 
This report presents an overview of the protections afforded by the state secrets privilege, a 
discussion of some of the many unresolved issues associated with the privilege, and a selection of 
high-profile examples of how the privilege has been applied in practice. The report also describes 
some considerations for Congress. 
Totten v. United States: State Secrets Subject Matter 
Jurisdictional Bar 
The Supreme Court first recognized the state secrets privilege in the 1876 case of 
Totten v. United 
States.6 
Totten and its progeny determined that dismissal of an action is warranted when the “very 
subject matter” of the case is “a state secret” and, as a result, “litigating the case to a judgment on 
the merits would present an unacceptable risk of disclosing state secrets.”7  
Totten involved a breach of contract claim brought against the government by the estate of a 
former Union Civil War spy for compensation owed for secret wartime espionage services.8 The 
Court dismissed the claim, articulating that “as a general principle, [] public policy forbids the 
maintenance of any suit in a court of justice, the trial of which would inevitably lead to the 
disclosure of matters which the law itself regards as confidential.”9 The Court reasoned that “[t]he 
service stipulated by the contract was a secret service; the information sought was to be obtained 
clandestinely, and was to be communicated privately; the employment and the service were to be

equally concealed.”10 Thus, under 
Totten, federal courts may not review controversies over secret 
espionage contracts. The Supreme Court affirmed the “
Totten bar”11 in 
Tenet v. Doe, a case 
involving a contract claim against the CIA brought by alleged Cold War spies.12 In 
Tenet, the 
Court held that “
Totten precludes judicial review in cases such as respondents’ where success 
depends upon the existence of their secret espionage relationship with the [g]overnment.”13  
In 2011, the Supreme Court again applied the 
Totten bar to dismiss a suit against the United States 
but this time outside the context of espionage contracts. In 
General Dynamics Corp. v. United 
States, the federal government asserted the state secrets privilege to prevent the disclosure of 
sensitive stealth technology in a defense contract dispute with a government contractor who had 
set forth a prima facie valid affirmative defense to the government’s allegation of breach of 
contract.14 Citing 
Totten and 
Tenet, the Court stated: “We think a similar situation obtains here, 
and that the same consequence should follow.”15 Namely, that the underlying subject matter of the 
suit rendered it non-justiciable and that the parties must be left “where they stood when they 
knocked on the courthouse door.”16  
In extending 
Totten into this new context and in refusing to find an enforceable contract, the 
Court held that “[w]here liability depends upon the validity of a plausible . . . defense, and when 
full litigation of that defense ‘would inevitably lead to the disclosure of’ state secrets, neither 
party can obtain judicial relief.”17 The Court explained that “[b]oth parties—the [g]overnment no 
less than petitioners—must have assumed the risk that state secrets would prevent the 
adjudication of claims of inadequate performance.”18 
United States v. Reynolds: State Secrets Evidentiary 
Privilege 
The state secrets privilege has also been invoked to protect certain pieces of evidence from 
discovery. The Supreme Court first articulated the modern analytical framework of this 
evidentiary state secrets privilege in the 1953 case of 
United States v. Reynolds.19 
Reynolds involved multiple wrongful death claims against the government brought by the widows of three 
civilians who died aboard a military aircraft that crashed while testing secret electronic 
equipment.20 The plaintiffs had sought discovery of the official post-incident report and survivors’ 
statements that were in the possession of the U.S. Air Force.21 The Air Force opposed disclosure 
of those documents, as the aircraft and its occupants were engaged in a “‘highly secret mission of

the Air Force’” at the time of the crash.22 The federal district court ordered the Air Force to 
produce the documents so that it could independently determine whether they contained 
privileged information.23 When the Air Force refused to provide the documents to the court, the 
district court ruled in favor of the plaintiffs on the issue of negligence,24 and the U.S. Court of 
Appeals for the Third Circuit (Third Circuit) subsequently affirmed the district court’s ruling.25 
The Supreme Court granted certiorari “[b]ecause an important question of the [g]overnment’s 
privilege to resist discovery [was] involved.”26 
Asserting the Privilege 
The Court has stated that “
Reynolds was about the admission of evidence.”27 In 
Reynolds, the 
Court identified several requirements to be met in order for the government to assert the privilege 
against revealing state secrets in litigation. The first requirement identified is a largely procedural 
hurdle to assure that the privilege is not “lightly invoked.”28 Nevertheless, this requirement is 
readily met through the written assertion of the privilege by the head of the department in control 
of the information in question after “personal consideration by that officer.”29 Second, the 
privilege belongs exclusively to the government and therefore cannot be validly asserted or 
waived by a private party.30 In cases in which the government is not a party, but the nature of the 
claim is such that litigation could lead to the disclosure of evidence that would threaten national 
security, the government must intervene and assert the state secrets privilege.31 The government’s 
failure to formally assert the privilege has previously been excused because courts have held that 
strict adherence to the requirement would have had little or no benefit.32 Finally, courts have held 
that the privilege may be raised at any time, including prospectively at the pleading stage of the 
litigation or during discovery in response to specific requests for information.33 
Evaluating the Validity of the Privilege 
In addition to the aforementioned requirements, the Court in 
Reynolds held that courts “must 
determine whether the circumstances are appropriate for the claim of privilege, and yet do so

Security Agency had submitted an affidavit stating that disclosing the contents of the documents would be a criminal

without forcing a disclosure of the very thing the privilege is designed to protect.”34 In contrast to 
the requirement that the government formally assert the privilege, the requirement that the court 
evaluate the validity of the government’s claim often “presents real difficulty.”35 The Court in 
Reynolds determined that the privilege should be found valid when a court is satisfied that there is 
a reasonable danger that disclosure “will expose military matters which, in the interest of national 
security, should not be divulged.”36 Accordingly, courts have held that the government “bears the 
burden of satisfying a reviewing court that the 
Reynolds reasonable-danger standard is met.”37 
Moreover, although the Supreme Court’s holding in 
Reynolds recognized that it is the role of the 
judiciary to evaluate the validity of a claim of privilege, the Court declined to require that courts 
automatically compel inspection of the underlying information.38 Therefore, while the privilege 
requires some deference to the executive branch, an independent evaluation of the claim of 
privilege is necessary so as not to abdicate control over evidence “to the caprice of executive 
officers.”39 In light of this dilemma, the Court chose to chart a middle course, employing a 
“formula of compromise” to balance the competing interests of oversight by the judiciary, the 
plaintiffs’ need for the evidence, and national security interests.40  
How thoroughly a court reviews the government’s assertion of the state secrets privilege varies. 
Generally, the depth of the inquiry corresponds to the court evaluating the opposing party’s need 
for the information and the government’s need to prevent disclosure.41 As part of this balancing, a 
court may go so far as to require the production of the evidence in question for 
in camera review 
where the non-government party’s need for the information is high.42 Under other circumstances, 
however, the evidence may be less central to the plaintiffs’ case such that the court may be 
satisfied that the evidence warrants protection based solely on the executive branch’s assertions.43 
If a court can determine that the privilege is valid without 
in camera review, the Supreme Court 
has held that it should not further “jeopardize the security which the privilege is meant to protect 
by insisting upon an examination of the evidence, even by the judge alone, in chambers.”44 
Whether a court may be satisfied without examining the underlying information will also be 
influenced by the amount of deference afforded to the government’s representations regarding the 
evidence in question. In 
Reynolds, the Court specified that the necessity of the underlying 
information to the litigation will determine “how far the court should probe in satisfying itself 
that the occasion for invoking the privilege is appropriate.”45 In the case of 
Reynolds, the Court 
explained that the Air Force had offered to make the surviving crew members available for 
examination by the plaintiffs.46 Because of this alternative avenue of information, the Court was

satisfied that the privilege was valid based primarily upon representations made by the 
government regarding the contents of the documents.47 Conversely, less deference to the 
government’s representations may be warranted where a private litigant has a strong need for the 
information.48 
When possible, courts have attempted to “disentangle” privileged evidence from non-privileged 
evidence to allow for the non-sensitive information’s release.49 One way to protect privileged 
information without excluding non-privileged evidence is to redact sensitive portions of a 
document rather than barring the entire piece of evidence. Some courts have questioned the 
prudence of using redaction to protect portions of documents that qualify for protection under the 
privilege out of a concern that pieces of “seemingly innocuous” information can create a 
“mosaic” through which protected information may be deduced.50 The “mosaic theory” is based 
on the principle that federal judges are not properly equipped to determine which pieces of 
information, when taken together, could result in the disclosure “of the very thing the privilege is 
designed to protect.”51 Adherence to the mosaic theory may result in greater judicial deference to 
the assertions of intelligence agencies.52 
The Effect of the Privilege 
If the privilege is appropriately invoked under 
Reynolds, it is absolute, and the disclosure of the 
underlying information cannot be compelled by the court. Significant controversy has arisen with 
respect to the question of how a case should proceed in light of a successful claim of privilege. 
Courts have varied greatly in their willingness to either dismiss a claim in its entirety or allow a 
case to proceed “with no consequences save those resulting from the loss of evidence.”53 Some 
courts have taken a more restrained view, holding that the privilege protects only specific pieces 
of privileged evidence, while others have taken a more expansive view, holding that the privilege,

In re Herring, 539 U.S. 940 (2003). The plaintiffs then filed their case 
with the district court, which granted the government’s motion to dismiss, in part on the basis of the court’s view that 
“against this political and technical backdrop, it seems that the accident investigation report may have reasonably 
contained sufficient intelligence, if not about the secret equipment or mission, then about ongoing developments in Air 
Force technical engineering, to warrant an assertion of the military secrets privilege.” Herring v. United States, 2004 
WL 2040272, at *9 (E.D. Penn. 2004). The Third Circuit affirmed, holding that because there was an “obviously 
reasonable truthful interpretation of the statements made by the Air Force,” there was no fraud upon the court.

The State Secrets Privilege: National Security Information in Civil Litigation 
 
with its constitutional underpinnings, often requires deference to the executive branch’s 
assertions, which may lead to dismissal.54 Whether the assertion of the state secrets privilege is 
fatal to a particular suit or merely excludes privileged evidence from introduction or discovery 
during litigation is a question that is highly dependent upon the specific facts of the case and, in 
the absence of Supreme Court precedent, whether there is binding appellate precedent for the 
particular circuit in which the case is brought. 
Pursuant to existing state secrets privilege jurisprudence, the valid invocation of the privilege may 
generally result in the outright dismissal of the case in three circumstances. First, a case may be 
dismissed if a plaintiff cannot establish a prima facie case without the protected evidence. For 
example, in 
Halkin v. Helms, the U.S. Court of Appeals for the D.C. Circuit (D.C. Circuit) was 
confronted with a claim of privilege regarding the National Security Agency’s (NSA’s) alleged 
interception of international communications to and from persons who had been targeted by the 
CIA.55 After deciding that the claim of privilege was valid, the D.C. Circuit affirmed the 
protection of that information from discovery.56 Although some non-privileged evidence that the 
plaintiffs were targeted by the CIA existed, the court dismissed the suit after deciding that the 
plaintiffs would not be able to establish a prima facie case of unlawful electronic surveillance 
without the privileged information.57 Although depriving litigants of an opportunity to obtain 
redress may seem like a harsh result, some courts have characterized dismissal to protect the 
greater good as the less harsh remedy.58 
Second, a case may also be dismissed where the privilege deprives a litigant of evidence 
necessary to establish a valid defense.59 In 
Molerio v. Federal Bureau of Investigation, a job 
seeker alleged that the Federal Bureau of Investigation (FBI) had disqualified him based upon his 
father’s political ties to socialist organizations in violation of the applicant’s and his father’s First 
Amendment rights.60 In response, the FBI asserted that it had a lawful reason to disqualify the 
plaintiff but claimed that its reason was protected by the state secrets privilege.61 After reviewing 
the FBI’s claim 
in camera, the D.C. Circuit agreed that the evidence of a nondiscriminatory 
reason was protected and that its exclusion would deprive the FBI of an available defense.62 
Therefore, the dismissal of that action was required once the privilege was determined to be 
valid.63 
Third, a court may conclude that a case must be dismissed where the “privileged information will 
be so central to the litigation that any attempt to proceed will threaten that information’s 
disclosure.”64 For example, in
 Sterling v. Tenet, the U.S. Court of Appeals for the Fourth Circuit

The State Secrets Privilege: National Security Information in Civil Litigation 
 
held that a racial discrimination suit brought by a covert CIA officer against the agency would 
necessarily center around the methods and operations of the CIA and must be dismissed as a 
result.65  
Given the relatively limited number of decisions in this area, there may be some uncertainty 
regarding what the effect of the privilege will be. For example, in 2017, the Department of 
Homeland Security (DHS) issued a binding operational directive requiring federal agencies to 
remove software directly or indirectly supplied by a specific cybersecurity company from all 
federal information systems based on concerns that such software posed a security risk.66 The 
excluded company sued DHS, alleging that the directive had been issued in violation of the 
Administrative Procedure Act (APA) because, 
inter alia, the directive was arbitrary, capricious, 
and unsupported by substantial evidence.67 In the context of APA challenges, courts review 
agency decisions based on the information that the agency had considered at the time it made the 
decision.68 In this case, plaintiffs alleged that DHS had stated that its decision was based on only 
unclassified information but stated that it had also reviewed classified information that supported 
its decision.69 The suit was ultimately dismissed on jurisdictional grounds before the court could 
address the merits of the plaintiffs’ APA claims,70 but it may still pose questions about what the 
proper resolution should have been if the government had invoked the state secrets doctrine with 
respect to information that might otherwise have been included in the administrative record.  
Assuming the court found the invocation of the privilege to be valid, it could be argued that the 
excision of such information from the administrative record is in tension with the principle that 
the court “should have before it neither more nor less information than did the agency when it 
made its decision” and that the decision should therefore be remanded to the agency because “the 
reviewing court simply cannot evaluate the challenged agency action on the basis of the record 
before it.”71 Alternatively, if the privileged information is central to the agency’s justification for 
its decision, removal of the information may deprive the agency of a valid defense to the APA 
challenge, and it could be argued that the suit should consequently be dismissed pursuant to 
Molerio v. FBI.72 Given this uncertainty, these questions may be an area in which future state 
secrets privilege litigation will focus.

The State Secrets Privilege: National Security Information in Civil Litigation 
 
Preemption of the State Secrets Privilege 
Courts frequently describe the evidentiary state secrets privilege as a common law doctrine that 
has arisen through a series of judicial decisions.73 At the same time, Congress has also enacted 
statutory provisions similarly addressing the use of or access to classified information in civil 
litigation, frequently alongside provisions authorizing private litigants to seek judicial review of 
actions the government has taken that may have been informed or based upon classified 
information.74 The Supreme Court has recognized that Congress may abrogate common law 
principles through statutory enactments, where the statute “speak[s] directly” to the question 
addressed by common law.75 Therefore, questions may arise as to whether these congressional 
enactments have otherwise affected the government’s ability to invoke the common law state 
secrets privilege. 
In 
FBI v. Fazaga, decided on March 4, 2022, the Supreme Court held that Congress did not 
displace the common law state secrets privilege by enacting legislation specifically addressing 
how national security information should be handled by courts in certain civil actions.76 The 
specific civil action involved in 
Fazaga arose in the context of FISA.77
 FISA provides a statutory 
framework to authorize the collection of foreign intelligence information via electronic 
surveillance but also provides a civil remedy for an “aggrieved person . . . who has been subjected 
to an electronic surveillance or about whom information obtained by electronic surveillance of

El-Masri, 479 F.3d at 303; Zuckerbraun v. Gen. Dynamics Corp., 935 F.2d 544, 546 (2d 
Cir. 1991). Though described as a common law doctrine, courts have frequently indicated that the state secrets privilege 
is also rooted in the “Art[icle] II duties” allocated to the President by the Constitution. United States v. Nixon, 418 U.S. 
683, 710 (1974). 
See also El-Masri, 479 F.3d at 303 (“Although the state secrets privilege was developed at common 
law, it performs a function of constitutional significance, because it allows the executive branch to protect information 
whose secrecy is necessary to its military and foreign-affairs responsibilities.”); Department of the Navy v. Egan, 484 
U.S. 518, 527 (1988) (“[The President’s] authority to classify

such person has been disclosed or used” in violation of federal law.78 
Aggrieved person is defined 
under FISA to include not just the target of electronic surveillance but “any other person whose 
communications or activities were subject to electronic surveillance.”79  
Because of the sensitive national security information likely to be included in the affidavits and 
supporting documentation accompanying a FISA application, the statute provides special 
procedures to be used when courts are asked to evaluate the legality of a FISA order.80 For 
example, if a criminal prosecution is based on information collected through FISA surveillance, 
the defendant may challenge the lawfulness of that collection and seek to suppress the resulting 
evidence. In addition to requiring the government to provide notice to “aggrieved person[s]” that 
FISA information is intended to be used against them,81 the statute directs that the court 
shall, notwithstanding any other law, if the Attorney General files an affidavit under oath 
that  disclosure  or  an  adversary  hearing  would  harm  the  national  security  of  the  United 
States,  review  
in  camera  and  
ex  parte  the  application,  order,  and  such  other  materials 
relating to the surveillance as may be necessary to determine whether the surveillance of 
the aggrieved person was lawfully authorized and conducted. In making this determination, 
the court may disclose to the aggrieved person, under appropriate security procedures and 
protective  orders,  portions  of  the  application,  order,  or  other  materials  relating  to  the 
surveillance only where such disclosure is necessary to make an accurate determination of 
the legality of the surveillance.82 
Thus, FISA creates a process in which the government may utilize information collected under 
FISA in “any trial, hearing, or other proceeding” against a private person “while withholding 
materials related to that surveillance . . . in the interests of national security” and also “allow[ing] 
an aggrieved person to challenge the government’s use of such evidence and have a court 
evaluate the lawfulness of the government’s actions.”83 In these cases, FISA generally requires 
the government to make the choice to “either disclose the material or forgo the use of 
surveillance-based evidence.”84 
The plaintiffs in 
Fazaga alleged that various covert FBI surveillance activities targeting them 
violated FISA.85 The government invoked the state secrets privilege and sought to prevent the 
disclosure or introduction of, among other things, information about the reasons the FBI may 
have targeted plaintiffs for investigation.86 Pursuant to 
Reynolds, the district court considered 
declarations made by the relevant government officials to determine whether the privilege had 
been validly invoked but did not examine the underlying evidence itself.87 Based on these

declarations, the district court found the privilege to be validly invoked and subsequently 
dismissed the suit for failure to establish a prima facie case.88 On appeal, the U.S. Court of 
Appeals for the Ninth Circuit (Ninth Circuit) held that “the district court should have relied on 
FISA’s alternative procedures for handling national security information” which require the court 
to examine the FISA application and other material 
in camera and 
ex parte.89 Specifically, the 
Ninth Circuit held that Congress had displaced the common law 
Reynolds state secrets privilege 
as applied to electronic surveillance within FISA’s purview.90 
The Supreme Court unanimously reversed the Ninth Circuit, holding that Congress had not 
displaced the state secrets privilege when it enacted FISA’s procedures for handling national 
security information.91 The Court identified two main reasons for its holding. First, in light of the 
general presumption against repeal of common law, the Court found FISA’s textual silence with 
respect to the state secrets privilege to be “strong evidence that the availability of the privilege 
was not altered in any way.”92  
Second, the Court held that the state secrets privilege was not incompatible with FISA’s 
procedures for handling national security information.93 Specifically, the Court held that the state 
secrets privilege and FISA “(1) require courts to conduct different inquiries, (2) authorize courts 
to award different forms of relief, and (3) direct the parties and the courts to follow different 
procedures.”94 With respect to the nature of the courts’ inquiry, the Court explained that FISA’s 
procedures are mainly concerned with the legality of surveillance while the state secrets privilege 
requires courts to consider whether disclosure would harm national security.95 Similarly, the 
Court held that a court cannot provide any relief under FISA if it determines that the surveillance 
was lawful,96 whereas a court may “order the disclosure of lawfully obtained evidence if it finds 
that disclosure would not affect national security.”97 Lastly, relating to procedure, the Court 
explained that FISA requires the Attorney General to request 
in camera and 
ex parte review of 
surveillance applications and information, while the state secrets privilege may be invoked by the 
head of the department that has control over the matter.98 
The Court’s decision in 
Fazaga was limited to the question of whether FISA displaced the state 
secrets privilege.99 Consequently, the Court did not express an opinion on whether FISA’s 
procedures are applicable only in suits brought 
by the United States, nor did the Court opine on 
what the appropriate remedy should be in light of the invocation of the state secrets privilege in

this case (i.e., dismissal or simple exclusion of the privileged evidence).100 As a result, the case 
has been remanded to the Ninth Circuit to resolve those questions.101 
Although the Court’s decision was specific to FISA, its reasoning would likely be applicable to 
other statutes that similarly address how the government must submit classified information to 
courts in the context of suits challenging some government action. For example, the Federal 
Acquisition Supply Chain Security Act of 2018 (FASCSA) established a Federal Acquisition 
Security Council to identify and address supply chain risks to federal information technology.102 
Among other things, FASCSA authorizes the Secretaries of Homeland Security and Defense and 
the Director of National Intelligence to issue orders excluding or removing sources and covered 
articles from agency procurement actions and information systems.103 Sources subject to such an 
order may seek judicial review of the order in the United States Court of Appeals for the D.C. 
Circuit.104 FASCSA provides that during such review, the government may include classified 
information in the administrative record and shall submit such information 
ex parte and 
in 
camera for the court to determine whether it supports the challenged order.105 Based on the 
Supreme Court’s decision in 
Fazaga, it could be argued that this provision of FASCSA does not 
displace the state secrets privilege. This view would rely on FASCSA’s classified information 
provision, like FISA’s, which does not expressly state an intent to displace the common law state 
secret privilege and is also primarily concerned with the court’s evaluation of the legality of the 
underlying government action rather than the risk to national security by disclosure.  
Deference to the Executive Branch 
The government has argued that courts should afford the “utmost deference” to its assertion of the 
state secrets privilege.106 That argument was at the center of the case involving Zayn Al-Abidin 
Muhammad Husayn (also known as Abu Zubaydah). Abu Zubaydah is currently a detainee at the 
U.S. Naval Station at Guantanamo Bay, Cuba, and was the first suspected Al Qaeda detainee 
rendered into CIA custody at various “black sites” abroad for interrogation, including allegedly at 
“Detention Site Blue” in Poland, from December 2002 to September 2003.107 He sought 
depositions from two former CIA contractors who helped devise the CIA’s “Enhanced 
Interrogation Program” for submission to prosecutors in Krakow, Poland, to assist in a criminal 
investigation of Polish officials’ “alleged complicity in claimed unlawful detention and torture of 
Zubaydah.”108 The district court granted the application for discovery, and the United States filed

a motion to intervene and to quash the subpoenas shortly after the court issued its order, arguing, 
among other things, that the state secrets privilege bars the requested discovery.109 
The government argued that the requested discovery was “predicated on a singular allegation that 
the United States can neither confirm nor deny without risking significant harm to national 
security—that is, whether or not the CIA conducted detention and interrogation operations in 
Poland or with the assistance of the Polish Government” and argued that the entire line of inquiry 
was foreclosed.110 The government further argued that the court should preclude discovery “in its 
entirety.”111 Abu Zubaydah countered that the former contractors could provide valuable evidence 
without confirming the location of the detention site or the cooperation of any particular 
government112 and have done so in another case without opposition from the government.113 The 
district court held that the 
Reynolds privilege, rather than the 
Totten bar, applied.114 
Citing the European Court of Human Right’s (ECHR’s) findings, the Polish government 
investigations, and the acknowledgement by the former President of Poland that Poland hosted a 
CIA detention site, the district court found unconvincing the government’s argument that 
“acknowledging, or denying, the fact the CIA was involved with a facility in Poland poses an 
exceptionally grave risk to national security.”115 The court further determined that, although 
confirming or denying Poland’s involvement would aid in Poland’s investigation, providing other 
operational details about Poland’s role could pose an exceptional risk to national security.116 The 
court stated that even seemingly innocuous facts could form a “mosaic” that could prove 
damaging.117 Accordingly, the court concluded that the deposition could not move forward 
without potential risk to national security.118 
A divided panel of the Ninth Circuit reversed the district court’s decision.119 The majority defined 
its task as a balance between the obligation to provide deference to executive branch decisions 
regarding national security120 and the “‘obligation to review the [claim of state secrets privilege] 
with a very careful, indeed a skeptical, eye, and not to accept at face value the government’s 
claim or justification of privilege.’”121

The State Secrets Privilege: National Security Information in Civil Litigation 
 
Although the majority agreed with the lower court that much of the information Abu Zubaydah 
sought—including the identities and roles of foreign individuals involved with the detention 
facility—was protected by state secrets privilege,122 it concluded that the district court’s effort to 
disentangle privileged information from non-privileged information was insufficient.123 The 
majority disputed the CIA director’s contention that absence of official confirmation is “the key 
to preserving an ‘important element of doubt about the veracity of the information,’”124 arguing 
that the statements of former contractors, who are not agents of the government, cannot serve as 
official verification of anything.125 Moreover, the majority held that there was little danger in 
exposing information that was already in the public realm.126 The majority also found it 
significant that Polish investigators were indirectly seeking the information, undercutting the 
director’s argument that the trust of foreign partners was at stake.127 Finally, the majority 
emphasized “the importance of striking ‘an appropriate balance . . . between protecting national 
security matters and preserving an open court system,’”128 opining that “[w]hile it is essential to 
guard the courts from becoming conduits for undermining the executive branch’s control over 
information related to national security, these concerns do not apply when the alleged state secret 
is no secret at all, but rather a matter that is sensitive or embarrassing to the government.”129 
The court remanded the case to the lower court with instructions to make an effort to disentangle 
non-privileged information that could be subject to deposition.130 The majority emphasized the 
limited nature of its holding, suggesting that the lower court might yet conclude that 
disentanglement is impossible and quash the subpoena.131 The dissent argued that the court should 
have provided greater deference to the CIA director.132 
The Ninth Circuit denied rehearing en banc over the dissent of 12 judges.133 Three concurring 
judges opined that rehearing was unnecessary given the narrowness of the panel decision, which

The serious legal errors in the majority opinion, and the national security risks those errors portend, 
qualified this case for en banc review. The majority opinion treats information that is core state 
secrets material as fair game in discovery; it vitiates the state secrets privilege because of 
information that is supposedly in the public domain; it fails to give deference to the CIA Director 
on matters uniquely within his national security expertise; and it discounted the government’s valid 
national security concerns because the discovery was only sought against government 
contractors—even though these contractors were the architects of the CIA’s interrogation program 
and discovery of them is effectively discovery of the government itself.

it characterized as enforcing the three-step 
Reynolds inquiry. The dissent also objected that the 
district court’s efforts to disentangle non-privileged information in this context would be “fraught 
with peril” and would themselves pose a risk to national security.134 
In 
United States v. Abu Zubaydah, the government asked the Supreme Court to overturn the Ninth 
Circuit decision.135 In the opening brief to the Court, the government urged the Court to find that 
the Ninth Circuit should have deferred to the CIA director, who declared that any information the 
contractors could provide would risk harm to U.S. national security, and should have quashed the 
subpoena in its entirety.136 Specifically, the government’s brief focused on its objection to the 
measure of deference the court below paid to the CIA’s declaration regarding the continued top 
secret nature of the CIA’s involvement with foreign partners during its clandestine detention and 
interrogation program.137 The government argued that the discovery statute for foreign 
proceedings does not permit discovery in this context because information central to the foreign 
proceeding is subject to a “legally applicable privilege.”138 In this context, the government 
contended that the 
Reynolds test suggests that discovery of sensitive information destined for a 
foreign tribunal should be denied based on a “facially plausible risk to the national security.”139 
The government thus objected to the Ninth Circuit’s “skeptical” review based on its own 
supposition about what is “public knowledge,”140 highlighting the difference between official and 
nonofficial disclosures.141 Specifically, the government rejected the notion that former CIA 
contractors are private parties not in a position to reveal state secrets142 and rebuffed the Ninth 
Circuit’s underestimation of the importance of providing U.S. intelligence partners “with an 
assurance of confidentiality that is as absolute as possible.”143  
In response, Abu Zubaydah and his attorney characterized the government’s position as a demand 
for blind deference from the judiciary whenever the government asserts the state secrets 
privilege,144 in effect imposing a complete bar on cases in their entirety even when some non-
privileged information is sought.145 They argued that the Ninth Circuit properly applied the 
Reynolds balancing test in this case146 and that the narrow question before the Supreme Court is 
whether the district court may order Mitchell and Jessen to testify (as they have done twice 
before)  about  nonprivileged  information;  or  if,  instead,  the  Government  may  prohibit 
disclosure of even nonprivileged information by invoking the state secrets doctrine.147

Abu Zubaydah emphasized that the information sought through deposition is similar to 
information the former contractors have already provided without the government’s invocation of 
the state secrets privilege.148 They argued that Polish investigators already had sufficient 
information to conclude that Abu Zubaydah was detained in Poland.149 In any event, they argued, 
there is no danger of “official confirmation” because the witnesses are not agents of the 
government.150 Disputing the government’s contention that the context of obtaining information 
for a foreign tribunal requires enhanced deference,151 the respondents argued that Abu 
Zubaydah’s inability to communicate with the outside world shows a strong necessity for the 
testimony requiring more careful judicial review.152 
The Supreme Court found in favor of the government and remanded the case with instructions to 
dismiss the discovery request,153 apparently without prejudice,154 although there was not complete 
consensus on the rationale.155 Justice Breyer, writing for a majority, characterized the issue as a 
“narrow evidentiary dispute” predicated on the questions for which Abu Zubaydah had initially 
sought depositions exactly as presented.156 The majority concluded that these questions, as 
written, relied on or would inevitably lead to a conclusion that the mistreatment occurred in 
Poland.157 The majority agreed with the government that the former CIA contractors were in a 
position to confirm or deny secret evidence158 and agreed with the government’s contention that 
such confirmation or denial would pose a threat to national security159 notwithstanding the fact 
that relevant information was already in the public domain.160

Having confirmed that information pointing to Poland as one site where Abu Zubaydah was 
tortured was subject to the state secrets doctrine, a majority considered Abu Zubaydah’s need for 
the depositions.161 The majority interpreted Abu Zubaydah’s argument that he did not necessarily 
need to elicit evidence establishing the location of the detention site as a concession that his need 
for the depositions was relatively insignificant.162 By emphasizing the narrow nature of the 
decision, the majority avoided making broad pronouncements regarding the level of deference 
courts owe the executive branch in evaluating assertions of the state secrets privilege or defining 
circumstances where a court might find it appropriate to examine evidence to disentangle 
privileged information from information that can safely be disclosed. 
Justice Thomas, joined by Justice Alito, filed an opinion disagreeing with respect to most of the 
opinion, but joined the opinion remanding the case and dismissing the discovery request.163 
Justice Thomas would have begun the inquiry with an evaluation of “the showing of necessity . . . 
made” by Abu Zubaydah and only then if necessary ask whether there is a “reasonable danger” 
that “military secrets are at stake.”164 Declaring Abu Zubaydah to be a terrorist,165 Justice Thomas 
emphasized that Abu Zubaydah “does not request this discovery for his own use. . . [but rather 
because] Polish prosecutors asked Zubaydah to file a discovery application after the United States 
repeatedly declined the prosecutors’ requests for information regarding CIA operations at an 
alleged detention site in Poland.”166 He argued the majority’s application of the 
Reynolds test, by 
evaluating the government’s claim of privilege first, “undermines the ‘utmost deference’ owed to 
the Executive’s national-security judgments.”167  
Justice Thomas’s evaluation of Abu Zubaydah’s need for the depositions concluded that there 
were three reasons Abu Zubaydah “failed to prove any nontrivial need for his requested 
discovery.”168 First, he argued the depositions would not provide Abu Zubaydah with meaningful 
relief because they would amount to “discovery on behalf of foreign authorities to help them 
prosecute foreign nationals who allegedly committed crimes in a foreign country.”169 Second, he 
argued Abu Zubaydah has “failed to pursue ‘an available alternative’” by not asking to submit a 
statement himself to the Polish prosecutors.170 Third, he argued that Abu Zubaydah clarified that 
he did not “need evidence about Poland specifically and seeks discovery only regarding the 
conditions of his confinement while in CIA custody.”171 Accordingly, he argued that Abu 
Zubaydah’s “dubious showing of necessity” alone required dismissal of the suit.172 
Justice Kagan filed an opinion concurring in part and dissenting in part, agreeing that the 
government has a substantial interest in maintaining secrecy regarding the location where Abu 
                                                 
courts because it leaves virtually no doubt as to the veracity of the information that has been confirmed.”).

Zubaydah was held in order to protect relationships with foreign intelligence partners173 but 
would have permitted Abu Zubaydah to rephrase his deposition questions to avoid implicating 
Poland. Justice Kagan would have permitted the district court to segregate “classified information 
about location while giving Zubaydah access to unclassified information about detention 
conditions and interrogation methods.”174  
Justice Gorsuch, joined by Justice Sotomayor, dissented, writing: 
There comes a point where we should not be ignorant as judges of what we know to be true 
as citizens. This case takes us well past that point. Zubaydah seeks information about his 
torture at the hands of the CIA. The events in question took place two decades ago. They 
have  long  been  declassified.  Official  reports  have  been  published,  books  written,  and 
movies  made about them. Still, the government seeks to have this suit dismissed on the 
ground it implicates a state secret—and today the Court acquiesces in that request. Ending 
this suit may shield the government from some further modest measure of embarrassment. 
But respectfully, we should not pretend it will safeguard any secret.175  
Justice Gorsuch first set forth what is already known about Abu Zubaydah’s treatment176 but 
argued that this information is missing relevant facts regarding Abu Zubaydah’s treatment during 
the time he was allegedly detained in Poland.177 He observed that Abu Zubaydah seeks that 
information pursuant to statute “for use in a proceeding in a foreign or international tribunal, 
including criminal investigations conducted before formal accusation,”178 and had sought an 
accommodation at the district court to avoid mentioning the location of the mistreatment.179 
Arguing that the breadth of the initial deposition request is now “beside the point,”180 Justice 
Gorsuch contended that information helpful to Abu Zubaydah could be elicited using code words 
and other familiar mechanisms to protect classified information.181  
Justice Gorsuch argued that accommodating both the government’s and Abu Zubaydah’s needs 
would not interfere in the constitutional separation of powers.182 Setting forth evidence of 
possible misuse of the state secrets doctrine in the past,183 Justice Gorsuch wrote that the Court 
need not “add fuel to that fire by abdicating any pretense of an independent judicial inquiry into 
the propriety of a claim of privilege and extending instead ‘utmost deference’ to the Executive’s 
mere assertion of one.”184

Framing the 
Reynolds test as one that both “guarantees a degree of independent judicial review 
[and] seeks to respect the Executive’s specially assigned constitutional responsibilities in the field 
of foreign affairs,” Justice Gorsuch explained his view that courts should “often [review] the 
evidence supporting the government’s claim of privilege 
in camera.”185 He observed that “the 
state secrets privilege protects the government from the duty to supply certain evidence, but it 
does not prevent a litigant from insisting that the government produce nonprivileged evidence in 
its possession.”186 Charging the majority with accepting the government’s conclusory assertions 
with respect to the dangers of revealing such information, Justice Gorsuch asserted that the Court 
had shifted the burden of proof to Abu Zubaydah to prove the opposite.187 The government, he 
wrote, “has not carried its burden of showing” that this case, if allowed to continue, would 
endanger relationships with foreign intelligence partners.188  
Even assuming that disclosure of the detention site would expose state secrets, Justice Gorsuch 
argued that the majority’s worry that deposing the CIA interrogators might lead them to 
“
inadvertently disclose the location of their activities” was insufficient to justify dismissing the 
entire case, given the tools available to avoid such an outcome.189 In the end, Justice Gorsuch saw 
no reason to force Abu Zubaydah to file a new lawsuit to get the depositions he needs,190 and he 
charged that the only real reason for the government to have this case dismissed in its entirety is 
to “impede the Polish criminal investigation and avoid (or at least delay) further embarrassment 
for past misdeeds.”191 
Other Examples of the State Secrets Privilege 
The United States has invoked the state secrets privilege in a wide array of cases, many of which 
have resulted in the outright dismissal of the plaintiffs’ claims. This section of the report provides 
a brief overview of a selection of recent high-profile uses of the privilege. 
Electronic Surveillance 
The state secrets privilege has played a large role in litigation arising from the Terrorist 
Surveillance Program (TSP). The TSP was a program, established during the George W. Bush 
Administration, that authorized the NSA to intercept various communications involving U.S. 
persons within the United States without first obtaining warrants under FISA.192 After the 
program was revealed in 2005, dozens of claims were filed challenging its legality. Most of these 
claims were filed against private telecommunications companies that had provided the NSA with 
telephone communication records, while others were filed against the NSA itself and individual 
government officials.193 Given the sensitive nature of NSA’s surveillance activities, the federal

government intervened in a majority of these cases filed against telecommunications companies, 
invoked the state secrets privilege, and asked that the cases be dismissed. These early assertions 
of the privilege saw little success. For example, in 
Hepting v. 
AT&T Corp., the district court 
denied the government’s motion to dismiss under the state secrets privilege.194 The court reasoned 
that the 
Totten bar was inapplicable under the facts of the case and that the “very subject matter” 
of the case was “hardly a secret.”195 The court explained that because of the broad public 
disclosures by AT&T and the government relating to the TSP, it could not conclude “that merely 
maintaining this action create[d] a ‘reasonable danger’ of harming national security.”196 The court 
declined to “defer to a blanket assertion of secrecy.”197 
In 2008, Congress passed the FISA Amendments Act (FAA),198 which granted the 
telecommunications companies retroactive immunity for assistance provided to NSA under the 
TSP.199 Accordingly, federal courts have dismissed most of the TSP-related claims filed against 
telecommunications companies pursuant to the protections provided in the FAA.200 
Challenges to the TSP program filed against the NSA or government officials, however, were not 
impeded by the immunity granted to telecommunications companies under the FAA. Perhaps the 
preeminent existing challenge to the TSP is 
Al-Haramain Islamic Foundation v. Bush.201 
Al-
Haramain involves a claim by a Muslim charity—designated as a terrorist organization by the 
United Nations—alleging that the NSA violated statutory, constitutional, and international law by 
intercepting communications through the TSP and providing those records to the Office of 
Foreign Assets Control (OFAC) of the Department of the Treasury, which subsequently froze Al-
Haramain’s assets.202 Whereas other plaintiffs had struggled to obtain standing to challenge the 
TSP,203 OFAC had inadvertently provided the Al-Haramain Islamic Foundation with a classified 
“top secret” document during the proceedings to freeze the organization’s assets that allegedly 
proved that the foundation had been subject to NSA surveillance.204 In response to the complaint, 
the government asserted the state secrets privilege both narrowly, with respect to the top secret 
document, and generally, arguing that the case must be dismissed as the “very subject matter” of 
the proceeding was a state secret.205 The district court denied the government’s motion to dismiss, 
holding that although the state secrets privilege was validly invoked and protected certain 
documents, the privilege did not require dismissal of the suit in its entirety.206 Al-Haramain had 
also argued that the state secrets privilege was preempted by statutory provisions of FISA

establishing procedures for a court to review FISA materials 
in camera, but the district court 
declined to rule on this question.207 
On an interlocutory appeal, the Ninth Circuit rejected the government’s motion to dismiss the 
case on the grounds that the subject matter of the claim was a state secret but accepted the 
government’s assertion of the privilege with respect to the top secret document inadvertently 
disclosed to Al-Haramain.208 The court held that enough was known about the TSP, including 
confirmation of the program by a number of government officials, that “the subject matter of Al-
Haramain’s lawsuit can be discussed . . . without disturbing the dark waters of privileged 
information.”209 Thus, the court held that dismissal under the state secrets privilege at such an 
“early stage” was not warranted.210 The court further concluded, after 
in camera review of the top 
secret document, that “disclosure of information concerning the [secret document] … would 
undermine the government’s intelligence capabilities and compromise national security.”211 
Therefore, the court held that the document itself was protected by the privilege and unavailable 
to the plaintiffs.212 
While the court in 
Al-Haramain did not dismiss the case under the state secrets privilege, it did 
determine that without the top secret document, the plaintiffs could not show the “concrete and 
particularized” injury necessary to establish standing.213 In short, the court determined that, 
without the secret document, Al-Haramain could not prove that it had actually been a subject of 
TSP surveillance. The court therefore dismissed the claim for lack of standing.214 Procedurally, 
this dismissal meant that the question of whether FISA preempted the state secrets privilege was 
now central to Al-Haramain’s ability to proceed with its suit, and the Ninth Circuit remanded the 
case to the district court to address that issue.215 Although the district court subsequently held that 
FISA did preempt the state secrets privilege,216 the suit was ultimately dismissed after the Ninth 
Circuit held that the government had not waived sovereign immunity and vacated the district 
court’s decision.217

government intervened and asserted the state secrets privilege in a 2008 tort case against 
Raytheon brought by the estate of a deceased U.S. Navy lieutenant. 
In 
White v. Raytheon, the wife of Navy combat pilot Nathan White alleged that a malfunction in 
Raytheon’s Patriot Air and Missile Defense System was responsible for the death of her husband, 
who had been killed when a wayward Patriot missile struck his F/A-18 fighter plane.219 During 
discovery, the United States intervened to assert the state secrets privilege through a declaration 
filed by the Secretary of the Army.220 The declaration asserted that any disclosure of “technical 
information regarding the design, performance, functional characteristics, and vulnerabilities, of 
the PATRIOT Missile system” along with any disclosure of the “rules of engagement authorized 
for, and military operational orders applicable” to the missile system would jeopardize national 
security.221 The Secretary also provided the court with a classified supplemental declaration that 
further elaborated on the impact of disclosing information specific to the case.222 After the district 
court judge’s 
in camera review of the supplemental declaration, the judge held that, although the 
plaintiff could potentially make out a 
prima facie case absent the privileged information, there 
was “no practical means by which Raytheon could be permitted to mount a fair defense without 
revealing state secrets.”223 The court thus concluded that it had “no alternative but to order the 
case dismissed.”224 
The Supreme Court case 
General Dynamic Corporation v. United States involved government 
contractors and the invocation of the state secrets privilege by the federal government.225 This 
case combined two lower court cases and centered around a contract entered into in 1988 to 
design and build a new stealth capable, carrier-based A-12 Avenger.226 By 1990, General 
Dynamics and McDonnell Douglas had fallen behind in the project and had missed required 
deadlines, which resulted in the Navy terminating the contract in 1991.227 As a result of the 
default termination, the Navy demanded that the contractors return $1.35 billion in progress 
payments.228 Although the Navy terminated the contract, it was the contractors who initiated 
litigation under the Contract Disputes Act.229 Filing with the U.S. Court of Federal Claims, the 
contractors argued that a lack of cooperation and support from the Pentagon had caused the 
project delays—resulting in a termination of convenience, rather than a termination for default.230 
One of the contractors’ chief arguments was that by not providing the companies access to its 
existing stealth technology, as it had allegedly promised,231 the Navy had breached its duty to 
                                                 
be considered government contractor cases.

The State Secrets Privilege: National Security Information in Civil Litigation 
 
“disclose critical information to a contractor that [was] necessary to prevent the contractor from 
unknowingly pursuing a ruinous course of action.”232 By withholding its “superior knowledge” of 
stealth technology, the contractors asserted that it was the Navy that had caused the default.233 
The Navy maintained that the contract was terminated due to default by the contractors.234 
The federal government also responded by invoking the state secrets privilege, arguing that “the 
government could not have an implied duty to reveal classified information pertinent to the A-12 
program that would threaten national security.”235 Ultimately, after a series of decisions by the 
U.S. Court of Federal Claims and the U.S. Court of Appeals for the Federal Circuit (Federal 
Circuit) ruling for and against the federal government, the Federal Circuit determined that the 
federal government had properly terminated the contract for default.236  
The Supreme Court vacated the Federal Circuit’s decision and remanded proceedings.237 The 
Court granted the petition for 
writ of certiorari to consider “what remedy is proper when, to 
protect state secrets, a court dismisses a Government contractor’s prima facie valid affirmative 
defense to the Government’s allegations of contractual breach.”238 In its opinion, the Court first 
distinguished 
General Dynamics from 
Reynolds, which it noted “was about the admission of 
evidence.”239 In contrast, the Court explained that “the state-secrets issue [in 
General Dynamics]
 
raises something quite different from a mere evidentiary point.”240 Specifically, the Court held 
that, like in 
Totten and 
Tenet, “[e]very document request or question to a witness would risk 
further disclosure, since both sides have an incentive to probe up to the boundaries of state 
secrets. State secrets can also be indirectly disclosed. Each assertion of the privilege can provide 
another clue about the Government's covert programs or capabilities.”241 Therefore, the Court 
held that “[w]here liability depends upon the validity of a plausible superior-knowledge defense, 
and when full litigation of that defense would inevitably lead to the disclosure of’ state secrets, 
neither party can obtain judicial relief.”242 In holding that neither the government’s claim nor the 
contractors’ defense could be “judicially determined” in light of the valid assertion of the 
privilege, the Court’s opinion focused solely on the consequence of invoking the privilege in the 
context of this case, rather than an examination of whether invoking the privilege was proper.243  
In crafting a remedy in this case, the Court held, as it did in 
Totten and 
Tenet, that following the 
government’s invocation of state secret privilege, the parties must be left “where they stood when 
they knocked on the courthouse door.”244 Thus, the government could not claim the $1.35 billion 
in progress payments, and the contractor could not pursue its claim for damages under the theory 
that “superior knowledge” was withheld.245 The Court, in an attempt to limit the future

application of its opinion in the state secrets context, declared that its decision “clarifie[d] the 
consequences of [the privilege’s] use only where it precludes a valid defense in Government-
contracting disputes, and only where both sides have enough evidence to survive summary 
judgment but too many of the relevant facts remain obscured by the state-secrets privilege to 
enable a reliable judgment.”246 
Employment Cases 
The state secrets privilege also arises in employment-related claims against national security 
agencies.247 The federal government has generally argued that these cases threatened to disclose 
“intelligence-gathering methods or capabilities, and disruption of diplomatic relations with 
foreign governments.”248 
Sterling v. Tenet, for example, involved a racial discrimination claim 
brought against the director of the CIA.249 Jeffrey Sterling, a CIA operations officer, alleged that 
he was subject to unlawful discriminatory practices during his employment at the CIA in violation 
of Title VII of the Civil Rights Act.250 In response, the CIA invoked the state secrets privilege and 
asked the district court to dismiss the case, relying on an unclassified and a classified declaration 
submitted by then-CIA Director George Tenet that alleged that litigating the factual issues of the 
claim would “compromise CIA sources and methods, threaten the safety of intelligence sources, 
and adversely affect foreign relations.”251 The district court granted the CIA’s motion to dismiss, 
concluding that the state secrets privilege “barred the evidence that would be necessary to state a 
prima facie claim.”252 
On appeal, the Fourth Circuit upheld the dismissal. The court asserted that Sterling could not 
prove employment discrimination “without exposing at least some classified details of the covert 
employment that gives context to his claims.”253 In dismissing the claim, the Fourth Circuit took a 
broad view of the consequences of a claim in which the “very subject matter” is itself a state 
secret, holding that “dismissal follows inevitably when the sum and substance of the case 
involves state secrets.”254 
The Fourth Circuit echoed its 
Sterling decision in 
Abilt v. CIA, affirming the dismissal of a 
lawsuit alleging disability discrimination by the CIA.255 Jacob E. Abilt, a covert CIA employee, 
brought an action in district court based on Title VII and the Rehabilitation Act,256 claiming that

the CIA discriminated against him by denying him opportunities to serve abroad and in a war 
zone due to his narcolepsy.257 He also alleged that the CIA failed to accommodate his disability 
and retaliated against him for filing an administrative complaint alleging discrimination.258 The 
government moved to dismiss and submitted in support a declaration from then-CIA Director 
John O. Brennan that asserted the state secrets privilege with respect to information concerning 
specific CIA programs and activities on which Abilt worked and information concerning the 
CIA’s employment of Abilt, his coworkers, and his supervisors.259 The district court granted the 
government’s motion and dismissed the case.260  
On appeal, the Fourth Circuit explained the three-step analysis it applies to resolve a claim of 
state secrets privilege.261 The court must first ascertain whether the procedural requirements under 
Reynolds were met.262 Next, the court must determine whether the information for which the 
privilege is sought in fact qualifies for it.263 Finally, if the first two steps are answered 
affirmatively, the court must decide how the matter should proceed in light of the successful 
privilege claim.264  
Citing a prior Fourth Circuit decision that had held that the state secrets privilege “performs a 
function of constitutional significance,”265 the court explained that the executive branch’s 
determination regarding the threat to national security posed by the possible disclosure of 
information is entitled to the “utmost deference.”266 The court also explained that each invocation 
of the privilege must be critically examined “to ensure that the state secrets privilege is asserted 
no more frequently and sweepingly than necessary.”267 This examination must nevertheless be 
conducted in such a way that does not “forc[e] a disclosure of the very thing the privilege is 
designed to protect.”268 Moreover, the court does not take into consideration the plaintiff’s need 
for the information in order to make his case.269 Rather, the court considers whether the “sum and 
substance” of the case involves state secrets, in which case dismissal inevitably follows.270 
The court identified three circumstances in which the privileged information is central to the case 
that dismissal is required: 
First, dismissal is required if the plaintiff cannot prove the prima facie elements of his or 
her claim without privileged evidence. Second, even if the plaintiff can prove a prima facie

case  without  resort  to  privileged  information,  the  case  should  be  dismissed  if  “the 
defendants  could  not  properly  defend  themselves  without  using  privileged  evidence.” 
Finally, dismissal is appropriate where further litigation would present an unjustifiable risk 
of disclosure.271 
Applying these principles, the court agreed with the district court that the CIA director had 
properly invoked the privilege and found there to be little doubt that the information he certified 
as requiring protection met the “reasonable danger” standard established by 
Reynolds.272 Turning 
to its analysis of how the litigation should proceed in light of the information placed off limits by 
the privilege, the court determined that the circumstances called for dismissal because the CIA 
would be unable to defend its actions as proper without the use of the privileged information.273 
The court explained that 
even if the CIA could, as Abilt suggests, proffer a legitimate nondiscriminatory reason for 
its actions without resort to privileged information, in properly litigating that reason, Abilt 
would be entitled to probe deeper into the CIA’s justifications “through cross-examination 
of the [CIA]’s witnesses.” In doing so, Abilt “would have every incentive to probe as close 
to the core secrets as the trial judge would permit.” “Such probing . . . would so threaten 
disclosure  of  state  secrets  that  the  overriding  interest  of  the  United  States  and  the 
preservation of its state secrets precludes any further attempt to pursue this litigation.”274 
Acknowledging the unfairness of the resulting dismissal to the plaintiff, the court found the 
“fundamental principle of access to court must bow to the fact that a nation without sound 
intelligence is a nation at risk.”275  
In 
Doe v. CIA, the U.S. Court of Appeals for the Second Circuit (Second Circuit) addressed a 
constitutional challenge to the actions that the CIA took to invoke the state secrets privilege and 
move for dismissal of a case,276 which the plaintiff argued effectively denied her access to the 
courts.277 Specifically, the plaintiff (who was the wife of a former CIA employee who remained in 
covert status), argued that the CIA denied her counsel access to secure communications and 
facilities to enable the preparation of an opposition to the CIA’s motion to dismiss in violation of 
her constitutional rights under the First Amendment.278 The Second Circuit disagreed, citing 
Reynolds for the proposition that “plaintiffs have no right of access to material that the 
government contends contains state secrets prior to the district court’s adjudication of that 
contention.”279 Furthermore, the court found that even though the plaintiff already knew some of 
the information for which the CIA sought to invoke the state secrets privilege, she did not have 
the right to use it to oppose that invocation in the district court.280 To permit plaintiffs to use the 
information to oppose the assertion of privilege, according to the court, “may present a danger of 
‘[i]nadvertent disclosure’—through a leak, for example, or through a failure or mis-use of the 
secure media that plaintiffs’ counsel seeks to use, or even through over-disclosure to the district

court 
in camera—which is precisely ‘the sort of risk that 
Reynolds attempts to avoid.’”281 
Consequently, the court held that the challenge failed on the merits. 
In 
Roule v. Petraeus, a former covert CIA employee brought a Title VII action against the CIA 
alleging discrimination based on the race and national origin of his wife, which he claimed 
resulted in the denial of work opportunities and advancement.282 The government moved to stay 
the case while internal deliberations regarding whether to invoke the state secrets privilege were 
underway and objected to providing discovery with respect to information that “may be” covered 
by the privilege.283  
In support of its motion to stay the proceedings, the government cited the multi-level Department 
of Justice (DOJ) procedures it follows before claiming the state secrets privilege in court.284 
According to the procedures, the DOJ invokes the state secrets privilege “only to the extent 
necessary to protect against the risk of significant harm to national security” and “will not defend 
an invocation of the privilege to conceal violations of the law, prevent embarrassment to any 
person, organization, or agency of the United States government, restrain competition, or prevent 
or delay the release of information that would not reasonably be expected to cause significant 
harm to national security.”285 The plaintiff argued that any more delay in the case while these 
procedures advanced would harm his ability to make his case due to the increasing possibility that 
witnesses would become unavailable or their memories would fade.286 The government also 
challenged the plaintiff’s discovery request, asserting that classified information is not 
discoverable in civil cases and that such discovery would pose a risk of harm.287 The judge agreed 
with the plaintiff, finding that discovery could continue with protective procedures designed to 
prevent disclosures, for example, by “redacting classified facts or replacing the names of covert 
employees with pseudonyms.”288 The judge characterized the government’s approach as “ask[ing] 
the court to trust the process blindly without any further information[,]” which she found to be 
“inconsistent with the court’s obligation to critically examine instances of the government’s 
invocation of the state secrets privilege.”289 The court declined to order the stay based on the 
record then before it, finding “the possibility that the government ‘may’” invoke the privilege 
insufficient to stay the case or discovery.290 Accordingly, where the government has not formally 
invoked the state secrets privilege under 
Reynolds, it may be possible for litigation to advance 
using protecting measures.

The State Secrets Privilege: National Security Information in Civil Litigation 
 
Targeted Killing 
In 
Al-Aulaqi v. Obama, the father of a U.S.-born Yemeni cleric and Specially Designated Global 
Terrorist291 brought a claim against the federal government challenging his son’s alleged inclusion 
on a so-called CIA target kill list.292 The plaintiff argued that inclusion on the CIA list meant his 
son was “subject to a standing order that permits the CIA or [Joint Special Operations Command] 
to kill him without regard to whether” lethal force was lawful under the circumstances, thus in 
violation of the Fourth and Fifth Amendments of the U.S. Constitution.293 The federal government 
responded by arguing that the plaintiff lacked standing to bring the claim on behalf of his son; 
that the claim was barred by the political question doctrine; and, in the alternative, that the claim 
should be dismissed under the state secrets privilege on the grounds that “specific categories of 
information properly protected against disclosure by the privilege would be necessary to litigate 
each of plaintiff’s claims.”294 
In support of the government’s claim of privilege, the Director of National Intelligence, the 
director of the CIA, and the Secretary of Defense submitted declarations asserting that disclosure 
of certain evidence connected to the case could cause “exceptionally grave damage to the national 
security of the United States.”295 Specifically, the government asserted that the litigation could 
lead to the disclosure of “information needed to address whether or not, or under what 
circumstances, the United States may target a particular foreign terrorist organization and its 
senior leadership” and “criteria governing the use of lethal force.”296 In addition to the public 
declarations, the government also provided the court with supplemental confidential declarations 
for 
in camera review.297 
The district court ultimately dismissed the case without reaching the state secrets privilege claim, 
finding that the plaintiff lacked standing and that his claims were non-justiciable under the 
political question doctrine.298 The court seemed to imply that dismissal would have been 
warranted under the privilege, noting in dicta that “given the nature of the state secrets assessment 
here based on careful judicial review of classified submissions to which neither plaintiff nor his 
counsel have access, there is little that plaintiff can offer with respect to this issue.”299 
Terrorist Screening Database 
The state secrets privilege has also arisen in claims associated with the Terrorist Screening 
Database (TSDB). For example, in 
Rahman v. Chertoff, a federal district court rejected the 
government’s claim of privilege.300 
Rahman involved a claim by a class of plaintiffs for wrongful 
                                                 
291 727 F. Supp. 2d 1 (D.D.C. 2010). The government alleges that Al-Aulaqi has significant ties to terrorist groups.

The State Secrets Privilege: National Security Information in Civil Litigation 
 
detention stemming from repeated encounters with law enforcement while crossing the border. In 
an effort to prove that they were “misidentified” or “overclassified,” the plaintiffs sought to 
obtain evidence proving their existence in the TSDB.301 Citing national security concerns, the 
federal government asserted the state secrets privilege with respect to any information “tending to 
confirm or deny whether the plaintiffs are now or ever have been listed in the TSDB.”302 In 
support of the claim, the government argued that if an individual who was engaged in terrorist 
activity had knowledge of whether he was included on the TSDB, that person may “alter the 
nature or extent of his terrorism-related activity, or take new precautions against surveillance, . . . 
change his appearance or acquire false identification to avoid detection, . . . [or] even go into 
hiding.”303 
The federal district court rejected the government claim of privilege and ordered that the 
information related to the TSDB be disclosed to plaintiffs pursuant to a protective order.304 In 
reaching its decision, the court determined that the plaintiffs had made a strong showing of 
necessity to obtain the information and that the defendants had “failed to establish that, under all 
the circumstances of this case, disclosure of that information would create a reasonable danger of 
jeopardizing national security.”305 The court noted that the government had raised only “general 
concerns” and declined to accept the government’s assertion that knowledge of one’s TSDB 
status would allow one to alter their activity so as to avoid surveillance.306 The court concluded 
that where a plaintiff has “been stopped at border entries on numerous occasions . . . there is little 
force to the argument that revealing their TSDB status will alert [the] plaintiffs for the first time 
that they have been under government scrutiny.”307 
Extraordinary Rendition 
Two cases from the Fourth Circuit and the Ninth Circuit can be viewed as exemplifying the 
varied conclusions federal courts have reached in ostensibly similar cases. Both cases involved 
civil claims against various government officials and private transportation companies associated 
with the government’s extraordinary rendition program. “Extraordinary rendition” has been 
described as a program administered by the CIA “to gather intelligence by apprehending foreign 
nationals suspected of involvement in terrorist activities and transferring them in secret to foreign 
countries for detention and interrogation.”308 The first case, 
El-Masri v. United States, involved a 
claim by Khaled El-Masri against the CIA and a number of private transportation companies 
alleging that the defendants unlawfully detained and interrogated him in violation of the U.S. 
Constitution and international law.309 El-Masri, a German citizen, alleged he had been detained in

Macedonia; turned over to the CIA; flown to Afghanistan, where he was held in a CIA facility; 
and then flown to Albania, where he was released.310 During his ordeal, El-Masri also alleged he 
was “beaten, drugged, bound, and blindfolded during transport; confined in a small, unsanitary 
cell; interrogated several times, and consistently prevented from communicating with anyone 
outside the detention facility.”311 
The second case, 
Mohamed v. Jeppesen Dataplan, Inc., involved a claim by five plaintiffs against 
Jeppesen Dataplan, Inc. for violations of the Alien Tort Statute stemming from the company’s 
role in providing transportation services for the extraordinary rendition program.312 The plaintiffs 
alleged that Jeppesen Dataplan, Inc. “provided flight planning and logistical support services to 
the aircraft and crew on all of the flights transporting the five plaintiffs among their various 
locations of detention and torture.”313 In both 
El-Masri and 
Jeppesen, the government asserted the 
state secrets privilege and argued that the suits should be dismissed because the issues involved in 
the lawsuits could not be litigated without risking disclosure of privileged information.314 
In 
El-Masri, the Fourth Circuit, citing both 
Totten and 
Reynolds, asserted that “the Supreme Court 
has recognized that some matters are so pervaded by state secrets as to be incapable of judicial 
resolution once the privilege has been invoked.”315 Although the court recognized that 
Totten has 
“come to primarily represent a somewhat narrower principal—a categorical bar on actions to 
enforce secret contracts for espionage,” the court concluded more broadly that 
Totten rested on 
the general proposition that “a cause cannot be maintained if its trial would inevitably lead to the 
disclosure of privileged information.”316 In the court’s opinion, any attempt by El-Masri to prove 
or disprove the allegations in the complaint would necessarily involve disclosing the internal 
organization and procedures of the CIA, as well as secret contracts with transportation 
companies.317 The circuit court thus determined that because the “central facts . . . that form the 
subject matter of El-Masri’s claim [] remain state secrets,” the court was required to dismiss the 
suit upon the successful invocation of the privilege by the government.318 The Supreme Court 
declined to review the 
El-Masri decision.319 
In reaching its decision, the Fourth Circuit emphasized the notion that while the privilege had 
been developed as a common law evidentiary privilege, the state secrets privilege performs a 
“function of constitutional significance.”320 The Fourth Circuit opinion contains express language

asserting that the state secrets privilege “has a firm foundation in the Constitution, in addition to 
its basis in the common law of evidence.”321 
In contrast, the Ninth Circuit in 
Mohamed v. Jeppesen Dataplan, Inc. initially held that the state 
secrets privilege excluded privileged evidence only from discovery or admission at trial and did 
not require the dismissal of the complaint at the pleadings stage.322 In characterizing 
Totten and 
Reynolds, the Ninth Circuit noted that “two parallel strands of the state secrets doctrine have 
emerged from its relatively thin history.”323 The opinion distinguished between the 
Reynolds privilege and the 
Totten bar, recognizing that dismissal under the 
Reynolds privilege was proper 
only when the privileged evidence prevented the plaintiff from establishing a 
prima facie case or 
the defendant from establishing a valid defense.324 “Neither does any Ninth Circuit or Supreme 
Court case law,” concluded the court, “indicate that the ‘very subject matter’ of any other kind of 
law suit is a state secret, apart from the limited factual context of 
Totten itself.”325 Limiting 
Totten to its facts, the Ninth Circuit refused to countenance any expansion of “
Totten’s uncompromising 
dismissal rule beyond secret agreements with the government.”326 
The Ninth Circuit in an en banc decision reversed its prior ruling.327 While criticizing the Fourth 
Circuit’s decision in 
El-Masri as an “erroneous conflation” of the 
Totten bar’s “very subject 
matter” inquiry with the 
Reynolds privilege, and expressly criticizing 
Totten as an ambiguous 
“judge-made doctrine with extremely harsh consequences,” the court determined that dismissal 
was nonetheless required under 
Reynolds,
 and
 not 
Totten,
 as there was “no feasible way to litigate 
Jeppesen’s alleged liability without creating an unjustifiable risk of divulging state secrets.”328 
In recognizing this third category of cases requiring dismissal under 
Reynolds, the Ninth Circuit 
noted that there exists a point in which “the 
Reynolds privilege converges with the 
Totten bar” to 
form a “continuum of analysis.”329 According to the court, included in the circumstances under 
which 
Reynolds merges with 
Totten is any case in which litigation would potentially result in an 
“unacceptable risk of disclosing state secrets.”330 The Supreme Court declined to review the 
case.331 
9/11 Litigation 
The government has used the state secrets doctrine to claim that certain information pertaining to 
FBI investigations is privileged and thus not subject to discovery in a lawsuit by 9/11 victims 
against Saudi Arabia and certain of its charities and officials for their alleged involvement or

support of the 9/11 attacks.332 In 2020, then-Attorney General William Barr filed a declaration 
with the court asserting the privilege with respect to FBI information that (1) “would indicate that 
a particular individual or entity is or was the subject of a national security investigation,” (2) 
“would reveal the reasons a particular  individual or entity is or was the subject of a national 
security investigation and information obtained as a result of that investigation,” (3) “would 
reveal sensitive sources and methods used in a national security investigation,” and (4) is 
“received from a foreign government with the understanding that it and the nature of the 
information sharing and cooperation between the FBI and foreign partners in a national security 
investigation will remain confidential.”333 
Plaintiffs urged the magistrate judge to reject the assertion of the privilege on the grounds that it 
had not been timely filed and they did not believe the Attorney General had personally reviewed 
the information sought to be withheld.334 The magistrate judge found no requirement for the 
government to assert any privilege prior to the plaintiffs’ submission of a motion to compel.335 
The judge also accepted at face value the Attorney General’s declaration that the assertion was 
based on his review of relevant information and found it to be supported by the detailed classified 
declaration of a subordinate.336 Recognizing that the plaintiffs were not in a position to review the 
classified information themselves to rebut the decision, the judge stated, “
In camera examination 
‘is necessarily conducted without benefit of criticism and illumination by a party with the actual 
interest in forcing disclosure’”337 and explained that “[i]n national security cases, some sacrifice 
to the ideals of the full adversary process are inevitable.”338  
The plaintiffs also argued that the FBI investigation of Saudi nationals on U.S. territory is 
essentially a domestic criminal matter and does not entail national security concerns.339 The FBI 
responded that “the September 11 attacks, perpetrated by a foreign terrorist organization, are 
inarguably a matter related to the national security of the United States.”340 Noting the 
considerable authority the executive branch has over classified information, the magistrate judge 
agreed with the FBI.341 The district court judge overseeing the litigation adopted the magistrate’s 
opinion.342 
The Biden Administration has reported that the FBI investigation is completed and promised to 
review the privileged information to determine what can be produced for plaintiffs.343 The first

Considerations for Congress 
In 2009, then-Attorney General Eric Holder issued a memorandum providing guidance for 
executive branch invocations of the state secrets privilege.345 The guidelines state that “the U.S. 
Government will invoke the privilege in court only when genuine and significant harm to national 
defense or foreign relations is at stake and only to the extent necessary to safeguard those 
interests.”346 DOJ has stated that it will defend invocation of the privilege only when the “agency 
seeking to assert the privilege makes a sufficient showing that assertion of the privilege is 
necessary to protect information the unauthorized disclosure of which reasonably could be 
expected to cause significant harm to the national defense or foreign relations,” including 
classified information and nonpublic unclassified information that could damage national security 
if disclosed.347 DOJ’s stated policy is to invoke the privilege narrowly, seeking dismissal only 
where necessary to guard national security.348 The privilege is not to be invoked to conceal 
wrongdoing, inefficiency, administrative error, or embarrassment or for delay or other improper 
reasons.349 The memorandum creates a review committee to assess assertions of the privilege and 
provides recommendations to the Attorney General, whose approval is necessary for the assertion 
to go forward.350 
Congress has the power to legislate on matters involving discovery, evidentiary rules and 
standards, and court process.351 On the other hand, classified information is a subject over which 
courts have tended to grant broad deference to the President, citing his constitutional authority.352 
Although invocations of the state secrets privilege are relatively rare,353 they may have stark 
results for civil litigants.354 Congress may review whether this process is effective in balancing

litigants’ needs against the legitimate need to safeguard national security and whether the process 
reflects congressional priorities. Congress may also consider codifying the process, enacting new 
or revised standards, or providing explicit guidance for courts to apply in evaluating assertions of 
the state secrets privilege.355 For example, Congress may consider adopting civil procedural rules 
akin to the Classified Information Procedures Act,356 which provides a means for making 
substitutions for classified materials for use in criminal trials, either by defendants or by the 
prosecution.357
