    for the Southern District of New York
    ARGUED: DECEMBER 4, 2018
    DECIDED: MAY 30, 2019
    Before: CABRANES, LIVINGSTON, Circuit Judges, and SCHOFIELD, District
    Judge.*
    Plaintiffs‐Appellants, the American Civil Liberties Union and
    the American Civil Liberties Union Foundation (jointly, “the ACLU”),
    requested documents concerning the legal authority for certain
    national security programs from Defendants‐Appellees, several
    federal agencies (jointly, “the Government”). After exhausting
    administrative remedies, the ACLU filed suit under the Freedom of
    Information Act (“FOIA”), requesting that the District Court compel
    disclosure. To defend the decision to withhold several documents, the
    Government invoked specific statutory exemptions, including FOIA
    Exemption 5, which protects from disclosure attorney‐client and
    deliberative communications. The District Court (Kimba M. Wood,
    Judge) granted summary judgment in the Government’s favor, holding
    that the agencies properly withheld the documents under FOIA. On
    appeal, the ACLU argues that Exemption 5 does not apply because the
    Government adopted or incorporated the disputed documents when
    it “relied on” the legal advice contained therein. We conclude that
    under Exemption 5, an agency (1) “adopts” a previously privileged
    document where the agency’s statements or behavior indicate that the
    agency treats the document as binding authority, and (2)
    “incorporates” a previously privileged document “by reference”

    JOSÉ A. CABRANES, Circuit Judge:
    The American people have the right to know the laws and
    policies that bind our government and its agencies. At the same time,
    government officials must be able to receive confidential legal advice
    and   deliberate   frankly.   Sometimes,    these   principles   appear
    contradictory. We can, however, accommodate both by carefully
    defining the boundary between law, on the one hand, and advice, on
    the other. Put simply, law binds. Accordingly, when inquiring whether
    a document constitutes an agency’s “effective law and policy” or
    whether it merely contains legal or policy advice, courts should inquire
    whether officials regarded the document as binding. This inquiry
    allows courts to distinguish between advice, which may be kept secret,
    and a government’s effective law and policy, to which a strong
    presumption of public access attaches.
    Plaintiffs‐Appellants, the American Civil Liberties Union and
    the American Civil Liberties Union Foundation (jointly, “the ACLU”),
    requested documents concerning the legal authority for certain
    national security programs from Defendants‐Appellees, several
    federal agencies (jointly, “the Government”). After exhausting
    administrative remedies, the ACLU filed suit under the Freedom of
    Information Act (“FOIA”), requesting that the District Court compel
    disclosure. To defend the withholdings, the Government invoked
    specific statutory exemptions, including FOIA Exemption 5, which
    protects   from     disclosure   attorney‐client    and    deliberative
    communications. The District Court (Kimba M. Wood, Judge) granted
    summary judgment in the Government’s favor, holding that the
    4
    agencies properly withheld the documents under FOIA. On appeal,
    the ACLU argues that Exemption 5 does not apply because the
    Government adopted or incorporated the disputed documents when
    it “relied on” the legal advice contained therein. We conclude that
    under Exemption 5, an agency (1) “adopts” a previously privileged
    document where the agency’s statements or behavior indicate that the
    agency treats the document as binding authority, and (2)
    “incorporates” a previously privileged document “by reference”
    where a formal agency opinion or decision explicitly relies on that
    document and its reasoning. We find no such adoption or
    incorporation to have occurred in this case. Accordingly, we affirm the
    judgment of the District Court.
    I.     BACKGROUND
    A. Executive Order 12,333 and the ACLU’s FOIA Request
    On December 4, 1981, President Reagan issued Executive Order
    12,333 (“EO 12,333”), entitled “United States Intelligence Activities.”1
    The order sought to regulate the “effective conduct of United States
    intelligence activities” and “protect[ ] . . . constitutional rights.”2
    Amended numerous times over the last four decades, EO 12,333 has
    long served as a “principal Executive Branch authority for foreign
    intelligence activities.”3 Today, it remains “one of the primary
    1   Exec. Order No. 12,333, 46 Fed. Reg. 59,941 (Dec. 4, 1981).

    authorities that allow agencies of the intelligence community . . . to
    gather foreign intelligence.”4
    In the wake of the terrorist attacks of September 11, 2001 and the
    subsequent expansion of intelligence operations, EO 12,333 became
    the subject of renewed public attention. On May 13, 2013, the ACLU
    submitted requests to several federal agencies “seeking the release of
    records that describe the government’s understanding of its
    surveillance authority under [EO] 12,333” and “the rules that regulate
    the government’s acquisition, retention, use, and dissemination of the
    communications of Americans swept up in that surveillance.”5 In
    requesting the documents, the ACLU invoked FOIA, a federal statute
    enacted in 1966 that facilitates the public release of most government
    records.6
    The agencies resisted disclosing the requested records. On

    ACLU filed suit under FOIA’s cause‐of‐action provision, seeking to
    compel the release of the documents.7
    During the litigation, the Government voluntarily produced
    hundreds of pages of responsive material. Nevertheless, the
    Government continued to withhold certain documents, claiming they
    were exempt from disclosure under specific statutory exemptions.
    In early 2016, the parties cross‐moved for summary judgment
    regarding the lawfulness of the Government’s decision to withhold the
    documents. On March 27, 2017, the District Court denied the ACLU’s
    motion in full, and granted the Government’s motion in part,
    approving the Government’s decision to withhold most documents,
    but requiring more detailed justifications for several remaining
    documents. The District Court then reviewed supplementary briefing
    from both sides on renewed cross‐motions for summary judgment
    with respect to the remaining documents. On August 17, 2017, the
    District Court granted the Government’s renewed motion for
    7 Under FOIA, requesting parties may petition a district court “to enjoin
    the agency from withholding agency records and to order the production of any
    agency records improperly withheld from the complainant.” 5 U.S.C.
    § 552(a)(4)(B). District courts must review an agency’s decision to withhold
    records de novo to ensure that the decision complies with FOIA’s substantive
    requirements.

    judgment and denied the ACLU’s cross‐motion.8 Judgment
    was entered on August 22, 2017.
    B. The Contested Documents
    On appeal, the ACLU contests the District Court’s rulings with
    respect to seven documents. 9
    OLC 10. The first document, “OLC 10,” is a 108‐page
    memorandum, dated May 6, 2004, from the Assistant Attorney
    General for the Office of Legal Counsel (“OLC”), Jack L. Goldsmith,
    III, to Attorney General Alberto Gonzales. The general functions of the
    OLC include “assisting the Attorney General in the performance of his
    functions as legal adviser to the President” in part by “advising as to
    the [ ] form and legality” of Executive orders and actions.10 The OLC
    memorandum, titled “Re: Review of the Legality of the STELLAR
    WIND Program,” examines a “highly classified and strictly
    8 See Am. Civil Liberties Union v. Nat’l Sec. Agency, No. 13 Civ. 9198 (KMW)
    (JCF), 
    2017 WL 6387731
    , at *1 (S.D.N.Y. Aug. 17, 2017) (“ACLU II”).
    9 Initially, the ACLU also challenged the decision to withhold an eighth
    document, “OLC 8.” While this appeal was pending, however, the Government
    reprocessed and released most of that document. Accordingly, the ACLU is “no
    longer seeking disclosure of that memorandum.” Reply Br. Appellants 3 n.1.

    compartmented program of electronic surveillance” authorized by
    President George W. Bush in response to the attacks of September 11,
    2001.11 The memorandum reviews the program’s history and analyzes
    its legality under EO 12,333, applicable statutes, and the United States
    Constitution.12
    The District Court concluded that OLC 10 is exempt from
    disclosure under FOIA Exemption 5 because the document is both an
    attorney‐client communication and a deliberative, pre‐decisional
    government memorandum.
    Intelligence Program Documents. The remaining six documents13
    each contains legal advice from Department of Justice attorneys
    concerning “[National Security Agency (“NSA”)] programs or other
    intelligence activities.”14
    According to a sworn declaration from a senior NSA official,
    five of these six documents (NSD 12, 13, 14, and 33, and NSA 11)
    concern “particular intelligence sources, and related methods used to

           13 The documents are identified individually as NSA 11 and NSD 12, 13,
    14, 33, and 49. Collectively, we refer to them as “the intelligence program
    documents.”

    collect and process foreign communications.”15 The disclosure of these
    documents “would [therefore] demonstrate the capabilities and
    limitations” of the United States’ signals intelligence systems.16
    Similarly, disclosure of the sixth document (NSD 49) would “tend[ ] to
    identify the targets of intelligence‐gathering efforts, reveal the specific
    collection techniques and methods employed, and contain details
    concerning the locations and timing of that collection.”17
    The District Court held that FOIA exempts these six intelligence
    program documents from disclosure because they contain classified
    and sensitive national security information.18
    C. The Government’s Public Statements
    It is undisputed that the contested documents have never been
    released in unredacted form. The Government has, however,
    discussed similar subject matter in several public statements. A central
    issue on appeal is whether these public statements—delivered over a
    period of 13 years—undermine the Government’s claims of attorney‐
    client and deliberative process privilege with respect to OLC 10.

    First, in a December 19, 2005 White House press briefing,
    Attorney General Gonzales discussed the “legal underpinnings” of the
    Stellar Wind program.19 In that briefing, Gonzales explained that the
    program was authorized by Congress’s 2001 Authorization for the Use
    of Military Force (“AUMF”), and was in any event a legal exercise of
    the President’s inherent constitutional authority as Commander‐in‐
    Chief. Gonzales did not mention OLC opinions in his prepared
    remarks, and when asked about the possibility of releasing an OLC
    opinion, responded, “Iʹm not confirming the existence of opinions or
    the non‐existence of opinions. I’ve offered up today our legal analysis
    of the authorities of this President.”20
    Second, on January 19, 2006, the Department of Justice
    transmitted to Congress a “White Paper” entitled “Legal Authorities
    Supporting the Activities of the National Security Agency Described
    by the President.”21 According to an accompanying letter, the
    document was “prepared by the Department of Justice to provide a
    detailed analysis of the legal basis” for certain NSA activities initiated

    briefly describes NSA surveillance activities and discusses their
    legality in light of the ongoing threat from Al‐Qaeda and pursuant to
    statutory authorities and the United States Constitution. The paper
    contains “[m]uch of the legal reasoning” first articulated in OLC 10.23
    Third, on February 6, 2006, Attorney General Gonzales stated,
    during a hearing before the Senate Judiciary Committee, that he
    “agreed with the [Office of Legal Counsel’s] legal analysis” concerning
    the Stellar Wind program.24
    Fourth, on July 10, 2009, the Inspectors General of five agencies
    completed and submitted a classified 747‐page comprehensive report
    concerning the Stellar Wind program (“the Joint IG Report”) to several
    committees of Congress.25 At the same time, the Inspectors General

    also publicly released a shorter, unclassified version of the report;26 the
    Government did not declassify and release a redacted version of the
    full report until April 2015.27 The full report discusses the drafting of
    OLC 10 under the heading “A New Legal Basis for the Program Is
    Adopted.”28
    Fifth, in February 2016, the Government made public a
    previously classified letter (“OLC 9”) from Deputy Assistant Attorney
    General John C. Yoo to Judge Colleen Kollar‐Kotelly, then Presiding
    Judge of the Foreign Intelligence Surveillance Court. 29 The letter,
    dated May 17, 2002, “discusses the President’s power to deploy
    expanded electronic surveillance techniques” and “outlines the legal
    justifications for such surveillance.”30

    II.    DISCUSSION
    We review a district court’s grant of summary judgment in
    FOIA litigation de novo.32
    In conducting our review, we first clarify the scope of FOIA and
    its exemptions, as well as the concepts of “working law,” “adoption”
    and “incorporation.” Applying these principles, we affirm the
    conclusion of the District Court that OLC 10 is exempt from disclosure
    under FOIA Exemption 5. We similarly affirm its conclusion that the
    six intelligence program documents are exempt from disclosure under
    FOIA Exemptions 1 and 3. Finally, we reject the ACLU’s request that
    we “order the re‐processing of the documents,” that is, compel the
    agencies to once again review the contested documents to ensure that
    only privileged and undisclosed, classified information is redacted.33

    A. FOIA and its Exemptions
    Passed in 1966, FOIA was intended to “permit access to official
    information long shielded unnecessarily from public view.”34 FOIA
    thus establishes a default rule in favor of Government disclosure,
    providing that an “agency, upon any request for records which
    (i) reasonably describes such records and (ii) is made in accordance
    with published rules . . . shall make the records promptly available to
    any person.”35 As the Supreme Court has explained, “virtually every
    document generated by an agency is available to the public in one form
    or another, unless it falls within one of the [FOIA]’s nine
    exemptions.”36 In accordance with FOIAʹs purposes, the statutory
    exemptions are “narrowly construed.”37
    Our case concerns three of these exemptions: Exemption 1
    exempts records that have been properly classified “in the interest of
    national defense or foreign policy.”38 Exemption 3 exempts records
    that a statute other than FOIA prohibits from disclosure.39 Finally,

    Exemption 5 exempts records that would be privileged in litigation.40
    The District Court upheld the redaction of OLC 10 under Exemption
    5, and the decision to withhold the intelligence program documents
    under Exemptions 1 and 3. We review each holding in turn.
    B. OLC 10 and FOIA Exemption 5
    Exemption 5 exempts from FOIA’s disclosure requirements
    “inter‐agency or intra‐agency memorandums [sic] or letters that
    would not be available by law to a party other than an agency in
    litigation with the agency.”41 This exemption “incorporate[s] into the
    FOIA all the normal civil discovery privileges,”42 including
    “traditional common law privileges against disclosure” such as “the
    attorney‐client and deliberative process privileges.”43 Here, the
    District Court upheld the redaction of OLC 10 pursuant to both
    privileges.44 We agree.
    1. The Attorney‐Client Privilege
    As we have explained in prior decisions, “[t]he attorney‐client
    privilege protects confidential communications between client and
    counsel made for the purpose of obtaining or providing legal

    assistance.”45 The privilege functions to “encourage attorneys and
    their clients to communicate fully and frankly and thereby to promote
    broader public interests in the observance of law and administration
    of justice.”46
    In the context of legal advice to government officials, “the
    privilege furthers a culture in which consultation with government
    lawyers is accepted as a normal, desirable, and even indispensable
    part of conducting public business. Abrogating the privilege
    undermines that culture and thereby impairs the public interest.”47
    The public interest in ensuring that government officials receive sound
    legal advice is at its apex when the programs about which advice is
    sought are secret and unlikely to be subject to litigation. In such cases,
    the frank exchange between government officials and their attorneys
    serves as a crucial—and maybe the only—safeguard in ensuring the
    legality of government action.
    The scope of the privilege follows directly from these purposes.
    The privilege protects “communications (1) between a client and his
    or her attorney (2) that are intended to be, and in fact were, kept

    confidential (3) for the purpose of obtaining or providing legal
    advice.”48
    OLC 10 meets these requirements easily. First, as reflected in the
    index the Government provided to the ACLU, OLC 10 was prepared
    by an OLC attorney (Assistant Attorney General Goldsmith) for an
    Executive Branch client (the Attorney General, and eventually, the
    President).49 The document is thus a communication between an
    attorney and a client.
    Second, the memorandum was written with the understanding
    that “OLC legal advice is generally kept confidential,”50 it was
    “communicated in confidence,”51 and “none of [its redacted portions]
    have been previously publicly disclosed.”52 The redacted sections of
    OLC 10 were thus intended to be, and actually were, kept confidential.
    And third, by its own description, OLC 10 is one in a series of
    memoranda which “advised” the Attorney General that certain
    presidential          actions      “would       satisfy      relevant      constitutional
    standards.”53 Moreover, as we have previously explained, OLC

    memoranda “provide, in their specific contexts, legal advice as to what
    a department or agency is permitted to do.”54 The communication thus
    provided legal assistance.55
    The ACLU does not seriously challenge this analysis. Instead, it
    argues that while OLC 10 was initially protected by the attorney‐client
    privilege, the Government subsequently waived the privilege through
    “official acknowledgments” and “public reliance.”56
    The ACLU’s assertion of a doctrine of waiver by “official
    acknowledgment” reflects a basic misunderstanding of the attorney‐
    client privilege. This privilege protects confidential communications
    between an attorney and a client. The “official acknowledgment”
    doctrine, however, precludes the Government from withholding

    , 687 (2d Cir. 2015)

    55 That the Attorney General might have transmitted OLC 10 to the White
    House does not change our analysis. As the OLC declarant explained, “[t]he
    principal function of OLC is to assist the Attorney General in her role as legal
    adviser to the President of the United States and to departments and agencies of
    the Executive Branch.” J.A. 244 ¶ 2; see also 28 C.F.R. § 0.25 (OLC advises as to the
    “form and legality” of proposed Executive orders, proclamations and regulations
    “prior to their transmission to the President.”). Accordingly, if OLC 10 was
    transmitted to the White House, then this transmission is also a communication
    between an attorney (the Attorney General) and a client (the White House);
    intended to be and kept confidential; and offered for the purpose of advising the
    President of the law governing a proposed action.

    information on the basis that it is classified after the Government has
    disclosed substantially the same information.57
    But such informational disclosures have no effect on whether a
    communication is protected by the attorney‐client privilege.58 The
    attorney‐client privilege “protects communications rather than
    information.”59 We have therefore explained that the attorney‐client
    privilege is not “lost by the mere fact that the information
    communicated [between attorney and client] is otherwise available to
    the public.”60 The concept of “official acknowledgment” is thus
    irrelevant to the Exemption 5 inquiry and cannot provide an
    independent basis for overcoming Exemption 5.61
    See N.Y. Times 
    I, 756 F.3d at 119
    ‐20. The principle underlying the “official
    57
    acknowledgment” doctrine is intuitive: once information is no longer secret, it
    cannot be protected simply “because it is secret.”

    This concept is instead suitable for the Exemptions 1 and 3 inquiries,
    61
    where the Government seeks to withhold documents on the ground that they
    contain classified information. See, e.g., N. Y. Times 
    I, 756 F.3d at 113
    , 120 (outlining
    the “three‐part test for ‘official disclosure,’ relevant to Exemption 1”).
    20
    By contrast, there is precedent for the ACLU’s argument that the
    Government’s “public reliance” on a document erodes its otherwise
    privileged status. While we have not used the precise phrase “public
    reliance,” we have indeed held that “the attorney‐client privilege may
    not be invoked to protect a document adopted as, or incorporated by
    reference into, an agency’s policy.”62
    This rule—that an incorporated or adopted document is no
    longer protected by privilege—mirrors the general “fairness doctrine”
    that governs the implicit waiver of privilege during litigation.63 As we
    have previously explained, “courts have found waiver by implication
    when a client testifies concerning portions of the attorney‐client
    communication . . . and when a client asserts reliance on an attorneyʹs
    advice as an element of a claim or defense.”64 And so we have
    consistently rejected parties’ attempts to withhold attorney‐client
    communications from a litigation adversary while relying on the same
    material to advance a claim in court.65 To put it simply, in court, a party

    may not wield a privileged communication as both a “shield and a
    sword.”66
    A similar principle applies when the Government “adopts” or
    “incorporates” a previously privileged document as its effective law
    and policy.67 Just as a litigating party may not offer a privileged
    communication to invoke the law while maintaining the privilege, so
    too the Government may not expressly adopt a privileged
    communication as its effective law or policy while maintaining the
    privilege. As we explain below, however, in this case the Government
    has neither expressly “adopted” OLC 10, nor “incorporated [it] by
    reference.”68
    2. The Deliberative Process Privilege
    In addition to the attorney‐client privilege, OLC 10 also meets
    the requirements of the “deliberative process privilege.”
    Like the attorney‐client privilege, the deliberative process
    privilege ensures “frank discussion” and protects agencies from being
    “forced to operate in a fishbowl.”69 But whereas the attorney‐client
    privilege promotes legal compliance in particular, the deliberative

    process privilege promotes reasoned policy‐making in general. As the
    Supreme Court has explained, “the frank discussion of legal or policy
    matters in writing might be inhibited if the discussion were made
    public,” and “the decisions and policies formulated would be the
    poorer as a result.”70 Accordingly, a document may be withheld
    pursuant to this privilege if it is: “(1) predecisional, i.e., prepared in
    order to assist an agency decisionmaker in arriving at his decision, and
    (2) deliberative, i.e., actually . . . related to the process by which policies
    are formulated.”71
    We think it clear that OLC 10 meets these criteria as well. As we
    have previously recognized, “OLC does not purport, and in fact lacks
    authority, to make policy decisions. OLC’s legal advice and analysis
    informs the decisionmaking of Executive Branch officials on matters
    of policy, but OLC’s legal advice is not itself dispositive as to any
    policy adopted.”72 Moreover, the unredacted portions of OLC 10 make
    clear that OLC’s role in the Stellar Wind authorization process was
    exclusively predecisional and deliberative. The document responds to

    the Attorney General’s request that OLC undertake a “thorough
    reexamination” of the legality of presidential directives concerning
    Stellar Wind.73 As OLC 10 explains, the Attorney General would
    consult OLC advice (such as OLC 10) in choosing whether to approve
    the program “as to form and legality.”74 OLC 10 thus preceded and
    directly related to the Attorney General’s approval decision.75
    3. The Limits of Exemption 5
    As we have previously explained, “[j]ust because a document
    satisfies [the above] requirements, however, does not mean that the
    deliberative process [or attorney‐client] privilege bars its disclosure.”76
    The ACLU therefore relies on three doctrines (which it calls
    “exceptions”) to argue that the Government must release additional
    portions of OLC 10.77 The ACLU claims (1) that OLC 10 contains
    “working law,”78 (2) that OLC 10 was “adopted,” or (3) that OLC 10

           75Indeed, the Attorney General’s approval of the Stellar Wind program “as
    to form and legality” was itself merely a predecisional and deliberative step
    before the actual policy decision was made by the President—i.e., the decision to
    reauthorize Stellar Wind.

    77  Properly understood, these doctrines are not “exceptions” to Exemption
    5 at all. Rather, they are tell‐tale indicators that, notwithstanding its appearance, a
    document simply is not protected by the deliberative process and attorney‐client
    privileges.

    24
    was “incorporated by reference” as agency policy.79 Although each of
    these terms emerges from our caselaw, ACLU’s arguments reveal that
    our prior decisions have not yet adequately defined these concepts and
    the relationship between them. We therefore accept the parties’
    invitation to clarify the contours of Exemption 5 and the doctrines that
    define its limits.
    a. Effective Law and Policy
    The Supreme Court first provided clear guidance regarding the
    limits of FOIA Exemption 5 in 1975 in N.L.R.B v. Sears, Roebuck & Co.80
    Drawing a clear distinction between deliberative material and
    documents that embody law and policy, the Supreme Court explained:
    Exemption 5, properly construed, calls for disclosure of
    all opinions and interpretations which embody the
    agency’s effective law and policy, and the withholding of
    all papers which reflect the agency’s group thinking in the
    process of working out its policy and determining what
    its law shall be.81
    The logic of this dichotomy is straightforward. The deliberative
    process privilege protects “communications received by the
    decisionmaker on the subject of the decision prior to the time the

    25
    decision is made” to ensure that the subsequent decision will be fully
    informed.82 By contrast, there is little need to preserve the
    confidentiality of discussions that take place after a decision has been
    made and rendered as the agency’s “effective law and policy.”83
    Although the conceptual distinction between pre‐decisional
    advice and post‐decisional explanation is clear, these materials might
    look quite similar in practice. For instance, a letter advising an agency’s
    leader on how to interpret a statute could look identical to a letter
    informing an agency subordinate about how the agency interprets a
    statute.
    In light of the potential for conflation, the doctrines of “working
    law,” “express adoption,” and “incorporation by reference” assist
    courts in applying this conceptual distinction.84 As we now explain,
    “working law” describes a category of post‐decisional material, and
    “express adoption” and “incorporation by reference” describe two
    methods by which pre‐decisional material can become post‐decisional.
    82

    id. 84 See
    Brennan 
    Ctr., 697 F.3d at 201
    (“The question of whether a document
    constitutes working law, or has been expressly adopted or incorporated by
    reference, then, are two paths to determining whether a withheld document
    constitutes what FOIA affirmatively requires to be disclosed.” (internal quotation
    marks omitted)).
    26
    i. Working Law
    As might be expected from the phrase itself, a document
    embodies an agency’s “working law” when the document binds
    agency officials or members of the public. In other words, working law
    announces what an agency’s law is, not what the law might be. Because
    such a document has operative effect—i.e., binding rather than
    persuasive power—it is inherently post‐decisional.
    In reaching this conclusion, we find instructive certain cases of
    the Court of Appeals for the District of Columbia Circuit (the “D.C.
    Circuit”), to which we have referred as “a specialist” in differentiating
    privileged material from working law.85 The D.C. Circuit has
    repeatedly employed a functional test to determine whether a
    document constitutes “working law,” inquiring whether the agency
    treats the document as binding.
    For instance, in Coastal States Gas Corp. v. Department of Energy,
    the case from which the working law doctrine emerged, the D.C.
    Circuit held that when an agency circulated and consulted certain
    documents as a source of binding authority, these documents were a
    post‐decisional “functioning body of secret law.”86 In that case, the
    plaintiffs sought disclosure of agency “memoranda from regional
    counsel to auditors . . . issued in response to requests for
    interpretations of regulations within the context of particular facts
    85   
    Id. at 200.

    27
    encountered while conducting an audit of a firm.”87 Evidence revealed
    that agency auditors did not simply regard the contested memoranda
    as persuasive or advisory, but that the memoranda “were retained and
    referred to as precedent.”88 In particular, the D.C. Circuit determined
    that auditors could not “freely disregard[]” these memoranda, but
    would request they be “rescinded, amended, or referred to a higher
    authority.”89 Bound by the directions contained therein, agency
    auditors then “actually applied” these directions in their “dealings
    with the public.”90 These features led the D.C. Circuit to conclude that
    the memoranda were not simply pre‐decisional legal advice, but the
    product of the decision‐making process. The agency had, through the
    circulation of these documents, “promulgated a body of secret law.”91
    Similarly, in Tax Analysts v. Internal Revenue Service, the D.C.
    Circuit found that legal memoranda issued by the IRS’s Office of Chief
    Counsel to officials in the field constituted “working law” even though
    the memoranda were “nominally non‐binding.”92 Despite their
    nominally advisory status, the memoranda had been distributed to
    ensure “the promotion of uniformity throughout the country on

    28
    significant questions of tax law.”93 Because these memoranda
    functioned as precedent rather than mere guidance, the D.C. Circuit
    concluded that they constituted “working law” rather than pre‐
    decisional advice.94
    As we have previously noted, “[o]ur Court has relatively little
    case law examining the ‘working law’ principle.”95 Those few
    precedents we do have, however, are entirely consistent with the
    principle that emerges from the D.C. Circuit cases—namely, that
    working law must be binding.96
    To decide the instant case, we need not reach a comprehensive
    definition of “working law.” But we do identify a few guiding
    principles to district courts faced with the task of determining whether
    a document is functionally binding and hence, “working law.” Such
    principles include: whether agency officials feel free to disregard the
    document’s instructions;97 whether an agency superior distributes the

    document to subordinates (rather than vice versa); 98 whether agency
    superiors direct their subordinates to follow the document’s
    instructions;99 whether the document is applied in the agency’s
    dealings with the public;100 and whether failure to follow a document’s
    instructions provides cause for professional sanction. These factors all
    provide indications as to whether a document has become binding on
    agency officials and therefore represents an agency’s “effective law
    and policy.”101
    ii. Express Adoption
    Occasionally, documents drafted as pre‐decisional material will
    ultimately be recycled and reissued as an agency’s “working law.” The
    doctrine of “express adoption” describes a process by which courts can
    discern whether a document first drafted as legal or policy advice has
    become an agency’s “effective law and policy.”
    For instance, an agency’s director might receive a memorandum
    from counsel advising him or her how to conduct a program in
    accordance with law. The director might then distribute that
    document to subordinates with instructions to obey the advice
    rendered therein. After such distribution, the document is no longer
    privileged. The reason is straightforward: while the initial

    591 F.2d 753
    , 774 (D.C. Cir. 1978).

    30
    communication was deliberative and pre‐decisional, the subsequent
    communication was a promulgation of “working law,” and therefore
    post‐decisional and no longer privileged.
    Because the adoption process is usually internal and hidden
    from public view, our Court’s “express adoption” cases have generally
    looked for external evidence that such adoption has occurred. In New
    York Times Co. v. Department of Justice (“New York Times I”), for instance,
    we held that certain Government disclosures fatally undermined the
    Government’s claims that an (initially classified and advisory) OLC
    memorandum was privileged.102 We noted that senior government
    officials engaged in “an extensive public relations campaign to
    convince the public” of the lawfulness of a government program,103
    and we observed that Attorney General Eric Holder invoked the
    disputed OLC memorandum as authority for the purposes of that
    campaign.104 We also highlighted the Senate testimony of then‐
    Assistant          to       the   President        for   Homeland      Security          and

    within which we can operate.”105 Together, these statements revealed
    that the OLC memorandum was no longer simply advice to a policy‐
    maker, but that the Government afforded the memorandum binding
    force within the Executive Branch as its “effective law and policy.”106
    Although less explicit, our decision in National Council of La Raza
    v. Department of Justice, rests on similar reasoning.107 In that case, we
    held that the Department of Justice expressly adopted a 2002 OLC

    as, or incorporated by reference into, an agency’s policy. Here, the Government
    has done so by publicly asserting that OLC advice ‘establishes the legal
    boundaries within which we can operate.’”) (internal quotation marks and
    citations omitted). In context, Mr. Brennan’s statement clearly refers specifically to
    OLC advice concerning the Government’s targeted killing program. See

    106 To be clear, the Government’s public statements serve as express
    evidence that the Government adopted the OLC memorandum as binding on the
    CIA. The remarks themselves do not, however, constitute adoption. Indeed, Mr.
    Brennan (who was not yet CIA Director when he made these statements), lacked
    the authority to adopt the OLC memorandum as binding authority. Adoption
    occurs when an agency itself accepts a previously deliberative document as
    binding, or actually acts (or refrains from acting) pursuant to the binding
    instruction (i.e., as “working law”) of that document. See Elec. Frontier Found. v.
    U.S. Depʹt of Justice,

    somewhat imprecise regarding whether “adoption” or “incorporation” provided
    the precise basis for our decision, or even whether there is a difference between

    as a case of express adoption.

    memorandum authorizing state governments to make arrests for civil
    violations of federal immigration provisions.108 We noted that the
    Attorney General and his senior staff repeatedly invoked the OLC
    memorandum not just to defend its own policy, but as embodying this
    new      policy.109           These   official   statements,   we     explained,
    “demonstrate[d] that [DOJ] regarded the Memorandum as the
    exclusive statement of . . . its new policy.”110 Moreover, DOJ’s effective
    promulgation of this OLC memorandum, as revealed in its public
    statements, carried substantive legal effects for “what a third party—
    state and local law enforcement—should and could lawfully do.”111 The
    statements therefore amounted to “powerful evidence that [DOJ]
    explicitly adopted the OLC Memorandum as part of its policy.”112
    Similarly, in Brennan Center for Justice v. Department of Justice, we
    found that public statements revealed that the United States Agency
    for International Development (“USAID”) had adopted an OLC
    memorandum.113 In particular, we pointed to a USAID policy

    precise basis for our decision. Again, however, as we understand and explain the

    document explaining that OLC had “determined” that a statutory
    funding restriction “only may be applied to foreign non‐governmental
    organizations and public international organizations.”114 Later, a
    senior USAID official confirmed that OLC’s determination had
    effectively dictated USAID’s new approach.115 Taken together, these
    USAID statements provided powerful evidence that senior agency
    officials related to OLC’s legal advice as binding authority, i.e. as
    “working law.” We therefore found that USAID adopted the OLC
    memorandum.
    iii.     Incorporation by Reference
    A close cousin to the doctrine of “express adoption” is the
    doctrine of “incorporation by reference.” Much like adoption, an
    agency incorporates a document by reference when it transforms a
    previously advisory document into binding “working law.”116 But
    whereas in “express adoption” cases we look for indications that an
    agency relates to the document as binding, in cases of “incorporation

           115Id. (citing congressional testimony of Randall Tobias, the U.S. Global
    AIDS Coordinator, who explained that he was “simply following the legislation
    and the advice to implement that”).
    116When a party claims that a previously privileged document has been
    “incorporated by refence,” a court’s task is usually to decide whether a reference
    to that document itself promulgates the document as binding law. By contrast, in
    most “express adoption” cases, the court inquires whether an agency’s remarks
    about a previously privileged document provide evidence that the document has
    already been promulgated as working law. See note 106, ante.
    34
    by reference,” we identify the agency’s enactment of that document as
    its law or policy through explicit textual reference in a final decision.117
    The D.C. Circuit first recognized the doctrine of “incorporation
    by reference” in a 1969 case, American Mail Line, Ltd. v. Gulick.118 There,
    the court held that by stating “publicly in [a] ruling that its action was
    based upon [a specific] memorandum, [and] giving no other reasons
    or basis for its action,” the Maritime Subsidy Board of the Department
    of Commerce forfeited that memorandum’s “intra‐agency status” and
    incorporated it into “a public record” that “must be disclosed.”119
    Six years later, in Sears, the Supreme Court endorsed the D.C.
    Circuit’s approach, holding that “if an agency chooses expressly to . . .
    incorporate by reference an intra‐agency memorandum previously
    covered by Exemption 5 in what would otherwise be a final opinion,
    that memorandum may be withheld only on the ground that it falls
    within the coverage of some exemption other than Exemption 5.”120
    Importantly, American Mail Line and Sears limit “incorporation
    by reference” to circumstances where the disputed memorandum is
    117   See, e.g., Gonzales v. Oregon, 
    546 U.S. 243
    , 254 (2006) (describing an
    agency interpretive rule as “[i]ncorporating the legal analysis of a memorandum .
    . . solicited from [OLC]”); see also Dispensing of Controlled Substances To Assist
    Suicide, 66 Fed. Reg. 56,607‐02 (Nov. 9, 2001) (promulgating an interpretive rule
    while incorporating a memorandum from the Attorney General).

    relied on in a “final opinion” or “ruling.” To decide the instant case,
    we need not define these terms precisely.121 But we think it clear that
    incorporation occurs only when the incorporating “opinion” is itself a
    document with functionally binding effect. This limitation is
    significant; a decisionmaker’s mere statements expressing his or her
    reliance on the reasoning of a separate memorandum do not amount
    to “incorporation” of that memorandum. The limitation is also
    sensible. Statements such as “we checked it with counsel,” or “we
    relied on the assessments of experts” are standard responses in
    congressional testimony or public statements. Appropriately, such
    statements cannot “incorporate by reference” external memoranda
    because such statements do not themselves have binding effect, either
    within the agency or on the public.
    In sum, a previously privileged document is subject to
    disclosure under the doctrine of “incorporation by reference” only
    when an agency’s formal opinion or determination of law or policy
    expressly references and relies on that document and its reasoning as
    the basis for a decision.
    b. Application
    The above principles dictate the outcome of this case. The ACLU
    argues that “reliance on legal analysis as a basis for its operational
    121 Among the open issues that we do not decide: whether an incorporating
    “final opinion” must (1) be public; (2) adjudicate the rights of individual, private
    parties; or (3) have the “force and effect of law,” see Chrysler Corp. v. Brown, 
    441 U.S. 281
    , 282 (1979).
    36
    decisions transforms that analysis into working law.”122 Not so. As we
    have explained, a document is only “working law” when it operates
    as functionally binding authority on agency decision‐makers. Here,
    OLC 10 was drafted as legal advice rather than binding authority and
    so was not “working law” when created.123 To be sure, a document
    first drafted as legal advice can still be adopted as working law or
    incorporated into agency decisions. But mere agreement with a
    document’s reasoning and conclusion is insufficient to transform
    advice into law. Instead, the document must be treated as binding by
    the agency (i.e. “adoption”) or explicitly relied upon in a formal
    decision (i.e. “incorporation by reference”).
    Here, there is no evidence that the Government ever “adopted”
    OLC 10 as binding; nor has the ACLU identified a single agency
    opinion that incorporates OLC 10 by reference.
    The ACLU’s arguments to the contrary are unavailing. The
    ACLU first points to a publicly released 2006 “White Paper” that
    contains “much of the legal reasoning” in OLC 10.124 As we have
    122   Reply Br. Appellants 3‐4.
    123See note 72, ante; see also Elec. Frontier 
    Found., 739 F.3d at 9
    (holding that
    an OLC opinion submitted to the FBI did not constitute “working law” because
    “OLC is not authorized to make decisions about the FBIʹs investigative policy, so
    the OLC Opinion cannot be an authoritative statement of the agencyʹs policy”); see
    also Citizens for Responsibility & Ethics in Washington v. United States Depʹt of Justice,
    
    922 F.3d 480
    , 486 (D.C. Cir. 2019) (“An OLC opinion in the latter category qualifies
    as the ‘working law’ of an agency only if the agency has ‘adopted’ the opinion as
    its own.”).

    37
    explained, however, disclosure of similar information to that contained
    in documents protected by the attorney‐client or deliberative process
    privileges does not waive the privilege. These privileges protect a
    communication, not information.125
    Next, the ACLU contends that a series of public statements by
    the Government indicates either that OLC 10 is working law, or that
    the Government expressly adopted OLC 10, or that it incorporated
    OLC 10 by reference.126 In particular, the ACLU draws our attention to
    (1) a press briefing during which Attorney General Gonzalez
    described OLC 10 as analyzing the “legal underpinnings” of the Stellar
    Wind program;127 (2) an internal agency report, which states that OLC
    10 provided “a new legal basis” for the program;128 and (3) Attorney
    125   See Section II.B.1, ante.
    126The Government urges us not to consider certain public statements by
    the Government that were available when the parties were before the District
    Court, but that the ACLU did not explicitly raise in its briefing below. These
    statements include the 2005 White House press briefing by Attorney General
    Gonzales, the 2006 Senate testimony (also by Gonzales), and the 2006 DOJ White
    Paper. We decline to disregard these materials. The Government is, of course,
    correct that we do not ordinarily hear arguments made for the first time on
    appeal. See, e.g., Spinelli v. Nat’l Football League, 
    903 F.3d 185
    , 198 (2d Cir. 2018).
    The ACLU’s reference to these statements does not constitute a new argument,
    however, but simply new evidence in support of old arguments, which “appeals
    courts may entertain.” Eastman Kodak Co. v. STWB, Inc., 
    452 F.3d 215
    , 221 (2d Cir.
    2006) Moreover, the Government’s subsequent public statements are precisely the
    sort of materials of which we may take judicial notice. See N.Y. Times 
    I, 756 F.3d at 110
    n.8. We therefore consider these statements in evaluating the ACLU’s claims.
    127   See 2005 Press Briefing, note 19, ante.
    128   See Joint IG Report, note 23, ante, at 37.
    38
    General Gonzalez’s testimony before the Senate, in which he stated
    that he “agreed with [OLC’s] legal analysis.”129
    These governmental disclosures illustrate, at most, the
    following: that OLC analyzed a legal question, that the Attorney
    General reviewed that analysis and agreed with it, and that the
    Attorney General then certified the program. None of the
    governmental disclosures indicate that the Attorney General (or any
    other official) ever distributed the OLC memorandum as binding
    precedent, or that officials within NSA or another agency ever
    regarded OLC 10 as binding authority.130 Nor do any of these
    disclosures represent an official decision or final opinion that explicitly
    references and relies on OLC 10; press briefings, congressional
    testimony, white papers and inspectors general reports might be
    informative, but they rarely, if ever, amount to official decisions or
    “final opinions.”
    129   See 2006 Hearing, note 24, ante.
    130 The section of the IG Report to which the ACLU points (entitled “A
    New Legal Basis for the Program is Adopted”) does not constitute evidence that
    OLC 10 was “expressly adopted” for several reasons: first, while the ACLU
    suggests that the “new legal basis” mentioned here refers to OLC 10, it seems that
    this section of the IG Report in fact describes a period prior to the writing of OLC
    10. Moreover, it is not even clear that the “new legal basis” discussed here refers
    to a specific document at all. On the contrary, it seems more likely that the phrase
    “new legal basis” simply refers to a new interpretation of already‐extant
    constitutional and statutory law. In other words, there is no reason to assume that
    the IG Report used the word “adoption” as we employ it in this opinion; the IG
    Report may simply describe a shift in Administration lawyers’ best
    understanding of applicable law, not a promulgation of a new “policy.”
    39
    It follows that OLC 10 was not created as working law, was
    never adopted as working law, and was never incorporated by
    reference. We therefore hold that OLC 10 is protected by the
    deliberative process and attorney‐client privileges, and was properly
    withheld under Exemption 5.
    C. The Intelligence Program Documents
    We also affirm the District Court’s holding that the six
    intelligence program documents are exempt from disclosure under
    FOIA Exemptions 1 and 3.
    Exemption 1 permits agencies to withhold records that have
    been “specifically authorized under criteria established by an
    Executive order to be kept secret in the interest of national defense or
    foreign policy and . . . are in fact properly classified pursuant to such
    Executive order.”131 As relevant here, Executive Order 13,526 permits
    classification of information if it pertains to “intelligence sources or
    methods” or “foreign relations or foreign activities of the United
    States,” where “unauthorized disclosure of the information reasonably
    could be expected to result in damage to the national security.”132
    FOIA Exemption 3 applies to records “specifically exempted
    from disclosure by statute.”133 Here, the Government has invoked
    131   5 U.S.C. § 552(b)(1)(A).
    132 Exec. Order No. 13,526, 75 Fed. Reg. 707, 707 § 1.1(a)(3)‐(4), 709 § 1.4(c)‐
    (d) (Dec. 29, 2009).
    133   5 U.S.C. § 552(b)(3).
    40
    several statutes, including the National Security Act, which requires
    that the Director of National Intelligence “protect intelligence sources
    and methods from unauthorized disclosure.”134 The ACLU does not
    dispute that each law qualifies as an exemption statute under
    Exemption 3.135
    The Government bears the burden of establishing that these
    exemptions apply, but it can do so by submitting affidavits showing
    that the statute’s application “appears logical or plausible.”136 Such
    affidavits must describe “with reasonably specific detail” how the
    withheld information “logically falls within the claimed exemption,”
    and must not be “controverted by either contrary evidence in the
    record nor by evidence of agency bad faith.”137
    Here, the Government has met its burden. The requested
    intelligence program documents concern highly sensitive surveillance
    programs.138 A senior intelligence official has attested that each
    134 50 U.S.C. § 3024(i)(1). In addition, the Government invokes statutory
    provisions related to the NSA, CIA, and communications intelligence activities
    generally. See 50 U.S.C. § 3605 (NSA); 50 U.S.C. § 3507 (CIA); 18 U.S.C. § 798
    (setting forth criminal penalties for disclosure of classified information).

    disputed document concerns “particular intelligence sources, and
    related methods used to collect and process foreign communications”;
    that the existence of these sources and methods is ”currently and
    properly classified”; and that disclosure of any meaningful part of
    these documents “would reveal core NSA foreign intelligence
    activities.”139
    In response to these declarations, the ACLU suggests that the
    Government failed to segregate and release non‐exempt legal
    analysis.140 The ACLU points out that “the legal memoranda within
    the packages are quite lengthy,”141 and that, in light of the “volume
    and breadth of public information” about the Stellar Wind program,
    “it strains credulity to claim that disclosure of pure legal analysis
    related to the program could damage national security today.”142
    Our credulity is not so easily strained. As we have previously
    observed, “the very fact that legal analysis was given concerning a
    planned operation would risk disclosure of the likelihood of that

    operation.”143 Similarly, disclosure of even “[m]inor details of
    intelligence information may reveal more information than their
    apparent insignificance suggests because, much like a piece of [a]
    jigsaw puzzle, each detail may aid in piecing together other bits of
    information even when the individual piece is not of obvious
    importance in itself.”144 We have long recognized that “in some
    circumstances legal analysis could be so intertwined with facts entitled
    to protection that disclosure of the analysis would disclose such
    facts.”145 Moreover, in this case, a senior national security official has
    affirmed that the legal analysis contained in these memoranda is
    “inextricably intertwined” with material that is both classified and
    protected by statute.146
    In light of “the relative competencies of the executive and
    judiciary,” we generally adopt a “deferential posture in FOIA cases
    regarding the uniquely executive purview of national security.”147

    Accordingly, we again decline to “second‐guess the predictive
    judgments made by the government’s intelligence agencies.”148
    We therefore hold that the surveillance approval packages were
    properly withheld under Exemptions 1 and 3.
    D. The Request for “Reprocessing”
    Lastly, we briefly address the ACLU’s request that we “order the
    re‐processing” of the contested documents in light of several
    governmental disclosures that post‐date the agency’s initial FOIA
    decision.149
    The ACLU identifies three such disclosures: (1) the full Joint IG
    Report (released in September 2015), (2) OLC 9 (released in February
    2016), and (3) OLC 8 (released while this appeal was pending).
    Although these disclosures are subsequent to the Government’s initial
    FOIA decision, the ACLU reminds us that it is “legally entitled to file
    a new FOIA request at any time,” and so urges us to consider these
    documents now in the interests of judicial economy.150
    The Government responds that these disclosures cannot be the
    basis for such an order because “[a]s a general rule, a FOIA decision is
    evaluated as of the time it was made and not at the time of a court’s
    148   
    Id. (internal quotation
    marks omitted).
    149   Br. Appellants 47.
    150   Reply Br. Appellants 20.
    44
    review.”151 Relying on precisely this rule, the District Court declined
    to order reprocessing.152
    Today, we reaffirm the general rule, and further hold that a
    court reviewing a FOIA decision must not order reprocessing simply
    to reassure itself that a correct decision remains current. As we have
    previously observed, “[t]o require an agency to adjust or modify its
    FOIA response based on post‐response occurrences could create an
    endless cycle of judicially mandated reprocessing each time some
    circumstance changes.”153 This case highlights the importance of our
    general practice. Indeed, one of the disclosures the ACLU urges us to
    consider—OLC 8—was released between the filing of the ACLUʹs
    appellate briefs. Imposing a continuing duty on agencies to update
    their responses to FOIA requests as “potentially relevant” documents
    (or, as is the case with the Joint IG Report, more sections of a certain
    document) are disclosed piecemeal renders agencies vulnerable to
    repeated reprocessing requests mid‐litigation. FOIA does not subject
    agencies or the courts to such “an endlessly moving target.”154
    While we have occasionally departed from our general rule and
    considered subsequent developments as part of a FOIA review, we
    have done so only in exceptional circumstances. And crucially, we

    have never ordered an agency to reprocess records simply to reassure
    ourselves that a FOIA decision remains up‐to‐date. In Florez v. Central
    Intelligence Agency, for instance, we remanded to the District Court in
    light of disclosures that post‐dated the Government’s decision to
    withhold particular documents.155 Critically, however, we noted that
    the agency had already voluntarily reprocessed the documents.156
    Thus, our decision imposed no additional burden on the agency.
    Similarly, in New York Times I, although we considered post‐
    decision disclosures in our review, we did so only because
    reprocessing was unnecessary to decide whether the withheld
    documents were subject to disclosure.157 In that case, the CIA had
    replied to a FOIA request relating to a CIA targeted killing program
    with a “Glomar response”158—neither confirming nor denying the
    existence of a document.159 The CIA justified its Glomar response by
    stating that “the government has never disclosed . . . whether the CIA
    has an operational role in the use of targeted lethal force or is

    inconsistent with some of its prior claims.” (internal quotation marks, citations,

    The term derives from the Hughes Glomar Explorer, a vessel purportedly
    158
    owned and operated by the CIA, which the Government refused to
    acknowledge. See Phillippi v. CIA,

    authorized to use such force.”160 This statement was directly
    contradicted by the post‐request disclosures that discussed the CIA
    program explicitly.161 There was thus no question that, at the time of
    the appeal, the Governmentʹs “Glomar response” was no longer
    sustainable.162
    The post‐request disclosures at issue in New York Times I were
    therefore not just potentially relevant, but clearly dispositive of the
    Government’s secrecy claims. Under such circumstances, declining to
    take judicial notice of public statements would serve no purpose.
    Ignoring such statements would have needlessly added work for the
    courts and simply delayed the inevitable for the agencies.
    In sum, our Court has only departed from the general rule—that
    an agency’s FOIA decision is evaluated as of the time it was made—
    when doing so is in the clear interest of judicial economy and would
    not burden the agency with prudential reprocessing. Those are not the
    circumstances here. The Government has not already reprocessed the
    material in light of the subsequent disclosures, and the subsequent

    47
    disclosures do not on their face plainly undermine the Government’s
    claimed privilege.
    Accordingly, we decline to order reprocessing in light of the
    subsequent disclosures of portions of the Joint IG Report, OLC 9, and
    OLC 8.
    III. CONCLUSION
    To summarize, we hold as follows:
    (1) A document reflects an agency’s “working law” when the
    agency regards that document as functionally binding
    authority. “Adoption” and “incorporation by reference” are
    means by which an otherwise privileged document becomes
    an agency’s “working law.”
    (2) “Express adoption” is a basis for disclosure of a previously
    privileged document where an agency’s statements indicate
    that it now acts (or refrains from acting) pursuant to the
    document’s functionally binding authority.
    (3) “Incorporation by reference” is a basis for disclosure of a
    previously privileged document where an agency’s formal
    opinion or ruling explicitly relies on that document and its
    reasoning in reaching a decision.
    (4) OLC 10 was properly withheld under FOIA Exemption 5
    (privileged communications).
    48
    (5) The six intelligence program documents at issue were
    properly withheld under FOIA Exemptions 1 (classified
    information) and 3 (material shielded from disclosure by
    other statutes).
    (6) Because FOIA decisions must be evaluated as of the time of
    the agency decision, courts should not order reprocessing
    simply to reassure themselves that a FOIA decision remains
    current in light of subsequent disclosures. We therefore
    decline to order reprocessing.
    For the foregoing reasons, the August 22, 2017 judgment of the
    District Court is AFFIRMED.
