    Before: NEWMAN, CALABRESI, and SOTOMAYOR, Circuit Judges.
    Appeal by the Government from the September 7, 2007, judgment of
    the United States District Court for the Southern District of New York
    (Victor Marrero, District Judge), in litigation concerning First
    Amendment challenges to the constitutionality of statutes governing
    the      issuance           and       judicial    review   of   National   Security   Letters
    (“NSLs”), 
    18 U.S.C. §§ 2709
    , 3511(b), which request records from
    providers of wire or electronic communication services. The judgment,
    stayed on appeal, enjoins FBI officials from (1) issuing NSLs under
    section    2709,     (2)    enforcing    the     nondisclosure      requirement     of
    subsection 2709(c), and (3) enforcing the provision for judicial
    review    of   the   nondisclosure      requirement     contained    in   subsection
    3511(b).
    The   Court     of    Appeals   construes    the   statutes    to    avoid   some
    constitutional challenges, rules that subsections 2709(c) and 3511(b)
    are unconstitutional to the extent that they impose a nondisclosure
    requirement on NSL recipients without placing on the Government the
    burden of initiating judicial review of such a requirement, rules that
    subsections 3511(b)(2) and (b)(3) are unconstitutional to the extent
    that, upon such review, a governmental official’s certification that
    disclosure may endanger the national security of the United States or
    interfere with diplomatic relations is treated as conclusive, modifies
    the district court’s injunction by limiting it to enjoining FBI
    officials from enforcing the nondisclosure requirement of section
    2709(c) in the absence of Government-initiated judicial review, and
    remands for a hearing.
    Affirmed in part, reversed in part, and remanded.

    JON O. NEWMAN, Circuit Judge.
    This appeal concerns challenges to the constitutionality of
    statutes     regulating   the    issuance    by     the   Federal   Bureau   of
    Investigation (“FBI”) of a type of administrative subpoena generally
    known   as    a   National   Security      Letter    (“NSL”)   to   electronic
    communication service providers (“ECSPs”). See 
    18 U.S.C. §§ 2709
    , 3511
    (collectively “the NSL statutes”).          ECSPs are typically telephone
    -3-
    companies or Internet service providers.              An NSL, in the context of
    this appeal,1 is a request for information about specified persons or
    entities who are subscribers to an ECSP and about their telephone or
    Internet activity.     Primarily at issue on this appeal are challenges
    to the provisions (1) prohibiting the recipient from disclosing the
    fact that an NSL has been received, see 
    18 U.S.C. § 2709
    (c), and (2)
    structuring judicial review of the nondisclosure requirement, see 
    id.
    § 3511(b).
    These challenges arise on an appeal by the United States from the
    September 7, 2007, judgment of the District Court for the Southern
    District of New York (Victor Marrero, District Judge), enjoining FBI
    officials from (1) issuing NSLs under section 2709, (2) enforcing the
    nondisclosure requirement of subsection 2709(c), and (3) enforcing the
    provisions    for   judicial   review    of    the    nondisclosure     requirement
    contained in subsection 3511(b).2 See Doe v. Gonzales, 
    500 F. Supp. 2d 379
     (S.D.N.Y. 2007) (“Doe II”).               The District Court ruled that
    subsections    2709(c)   and   3511(b)        are    unconstitutional    on   First
    Amendment and separation-of-powers grounds, see 
    id. at 405-06, 411-13
    ,

    For authority to issue NSLs in other contexts, see 
    12 U.S.C. § 3414
    (a)(5) (financial records); 15 U.S.C. § 1681u (credit history);
    15 U.S.C. § 1681v (full credit reports); 
    50 U.S.C. § 436
     (information
    concerning investigation of improper disclosure of classified
    information).

    416-22, and that subsection 2709(c) could not be severed from section
    2709, see 
    id. at 424-25
    .
    We agree that the challenged statutes do not comply with the
    First Amendment, although not to the extent determined by the District
    Court, and we also conclude that the relief ordered by the District
    Court is too broad.   We therefore affirm in part, reverse in part, and
    remand for further proceedings.
    Background
    The parties. The Plaintiffs-Appellees are an Internet service
    provider (John Doe, Inc.), the provider’s former president (John Doe),
    the American Civil Liberties Union (“ACLU”), and the American Civil
    Liberties Union Foundation (“ACLUF”).3     The Defendants-Appellants are

    There is some slight confusion as to the status of John Doe,
    Inc., and John Doe in this litigation, but the confusion has no
    bearing on any of the issues or the resolution of this appeal. The
    captions of the District Court’s first and second opinions list John
    Doe as a plaintiff, but do not list John Doe, Inc., see Doe v.
    Ashcroft, 
    334 F. Supp. 2d 471
     (S.D.N.Y. 2004) (“Doe I”), and Doe II,
    
    500 F. Supp. 2d 379
    , and there is no reference to John Doe, Inc., in
    either opinion.    The first opinion states that John Doe is “an
    internet access firm.” Doe I, 
    334 F. Supp. 2d at 475
    . The second
    opinion does not indicate whether John Doe is the corporation or its
    former president. The second opinion grants in part the motion “of
    John Doe.” See Doe II, 
    500 F. Supp. 2d at 425
    .         However, the
    Plaintiffs’ second amended complaint lists as parties both the
    corporation and the former president, and the briefs filed in this
    Court by all parties include John Doe, Inc., and John Doe in the
    captions as the Plaintiffs-Appellees. We will assume that both the
    corporation and its former president have been and continue to be
    Plaintiffs-Appellants, and they are so identified (by pseudonyms) in
    the caption of this appeal.

    the Attorney General, the Director of the FBI, and the General Counsel
    of the FBI, all sued in their official capacities.
    The NSL.    In February 2004, the FBI delivered the NSL at issue in
    this litigation to John Doe, Inc.    The letter directed John Doe, Inc.,
    “to provide the [FBI] the names, addresses, lengths of service and
    electronic communication transactional records, to include          [other
    information] (not to include message content and/or subject fields)
    for [a specific] email address.”          The letter certified that the
    information     sought   was   relevant   to   an   investigation   against
    international terrorism or clandestine intelligence activities and
    advised John Doe, Inc., that the law “prohibit[ed] any officer,
    employee or agent” of the company from “disclosing to any person that
    the FBI has sought or obtained access to information or records”
    pursuant to the NSL provisions.      The letter also asked that John Doe
    provide the relevant information personally to a designated FBI
    office.

    Subsection     2709(a)   imposes    a    duty   on   ECSPs   to   comply   with
    requests for specified information about a subscriber, and subsection
    2709(b) authorizes the Director of the FBI and other FBI officials to
    request specified information about a subscriber from ECSPs.                     The
    texts of subsections 2709(a) and (b), as they existed in 2004, when

    Subsection 2709(a) provides:

    information and toll billing records information, or
    electronic communication transactional records in its
    custody or possession made by the Director of the Federal
    Bureau of Investigation under subsection (b) of this
    section.

    The statute was not intended to require disclosure of the content
    of electronic communications. See S. Rep. No. 99-541, at 44 (1986), as
    reprinted in 1986 USCCAN 3598.
    Subsection 2709(b) provides:
    (b) Required Certification. The Director of the Federal
    Bureau of Investigation, or his designee in a position not
    lower than Deputy Assistant Director at Bureau headquarters
    or a Special Agent in Charge in a Bureau field office
    designated by the Director, may –
    (1) request the name, address, length of service, and
    local and long distance toll billing records of a person or
    entity if the Director (or his designee) certifies in
    writing to the wire or electronic communication service

    The     lawsuit   and   the    District   Court’s   first   decision.   The
    Plaintiffs filed this lawsuit in April 2004 and an amended complaint
    in May 2004.     They contended that section 2709 violated the First and
    Fourth Amendments by authorizing the FBI to compel the disclosure of
    against international terrorism or clandestine intelligence
    activities, provided that such an investigation of a United
    States person is not conducted solely on the basis of
    activities protected by the first amendment to the
    Constitution of the United States; and
    (2) request the name, address, and length of service
    of a person or entity if the Director (or his designee)
    certifies in writing to the wire or electronic communication
    service provider to which the request is made that the
    information   sought    is   relevant   to   an   authorized
    investigation to protect against international terrorism or
    clandestine intelligence activities, provided that such an
    investigation of a United States person is not conducted

    (c) Prohibition of certain disclosure. No wire or

    that the Federal Bureau of Investigation has sought or
    obtained access to information or records under this

    private records relating to constitutionally protected speech and
    association; they also contended that the nondisclosure requirement of
    subsection 2709(c) violated the First Amendment by permanently barring
    NSL recipients from disclosing that the FBI had sought or obtained
    information from them.
    On the Plaintiffs’ motion for summary judgment, the District
    Court ruled primarily that section 2709 (presumably the disclosure
    requirements of subsections 2709(a) and (b)) was unconstitutional
    under the Fourth Amendment because it authorized “coercive searches
    effectively immune from any judicial process,” Doe v. Ashcroft, 
    334 F. Supp. 2d 471
    ,    494-506      (S.D.N.Y.    2004)   (“Doe      I”),    and   that   the
    nondisclosure requirement of subsection 2709(c) was unconstitutional
    under   the    First       Amendment   because     it   was   an    unjustified      prior
    restraint and a content-based restriction on speech, see 
    id.
     at 511-
    25.     Nearly       one    year   later,   a     District    Court       in   Connecticut
    preliminarily enjoined enforcement of the nondisclosure requirement of
    subsection 2709(c), finding a probability of success on the claim that
    subsection 2709(c) was unconstitutional under the First Amendment
    because it was an unjustified prior restraint and content-based
    restriction. See Doe v. Gonzales, 
    386 F. Supp. 2d 66
    , 73-75, 82 (D.
    Conn. 2005) (“Doe CT”).

    (c) (West Supp. 2008).           First, although
    leaving intact subsections 2709(a) and (b), requiring compliance with
    NSLs, Congress amended the nondisclosure prohibition of subsection
    2709(c) to require nondisclosure only upon certification by senior FBI
    officials that “otherwise there may result a danger to the national
    security   of    the   United   States,    interference    with   a   criminal,
    counterterrorism, or counterintelligence investigation, interference
    with diplomatic relations, or danger to the life or physical safety of

       §   2709(c)(1)     (“the   enumerated   harms”).6    The
    Reauthorization Act amended subsection 2709(c) by replacing the single
    paragraph of former subsection 2709(c) with four subdivisions, the
    fourth of which was amended by the Additional Reauthorization Act. We
    consider below the text of amended subsection 2709(c), which is set

    whom disclosure is necessary to comply with the NSL or for an
    attorney, see

    Subsection 2709(c), as amended by the Additional Reauthorization
    Act, provides:
    (c) Prohibition of certain disclosure.–
    (1) If the Director of the Federal Bureau of Investigation,
    or his designee in a position not lower than Deputy
    Assistant Director at Bureau headquarters or a Special Agent
    in Charge in a Bureau field office designated by the
    Director, certifies that otherwise there may result a danger
    to the national security of the United States, interference
    with a criminal, counterterrorism, or counterintelligence
    investigation, interference with diplomatic relations, or
    danger to the life or physical safety of any person, no wire
    or electronic communications service provider, or officer,
    employee, or agent thereof, shall disclose to any person
    (other than those to whom such disclosure is necessary to
    comply with the request or an attorney to obtain legal
    advice or legal assistance with respect to the request) that
    the Federal Bureau of Investigation has sought or obtained
    access to information or records under this section.
    (2) The request shall notify the person or entity to whom
    the request is directed of the nondisclosure requirement
    under paragraph (1).
    (3) Any recipient disclosing to those persons necessary to
    comply with the request or to an attorney to obtain legal
    advice or legal assistance with respect to the request shall
    inform such person of any applicable nondisclosure
    requirement.   Any person who receives a disclosure under
    this subsection shall be subject to the same prohibitions on
    disclosure under paragraph (1).
    (4) At the request of the Director of the Federal Bureau of
    Investigation or the designee of the Director, any person
    making or intending to make a disclosure under this section
    shall identify to the Director or such designee the person
    to whom such disclosure will be made or to whom such
    disclosure was made prior to the request, except that
    nothing in this section shall require a person to inform the
    Director or such designee of the identity of an attorney to
    whom disclosure was made or will be made to obtain legal
    advice or legal assistance with respect to the request under
    subsection (a).

    added provisions for judicial review, now codified in section 3511, to
    permit the recipient of an NSL to petition a United States district
    court for an order modifying or setting aside the NSL, see 
    18 U.S.C.A. § 3511
    (a) (West Supp. 2008), and the nondisclosure requirement, see
    
    id.
     § 3511(b).    The NSL may be modified if “compliance would be
    unreasonable, oppressive, or otherwise unlawful.” Id. § 3511(a).   The
    nondisclosure requirement, which prohibits disclosure by the NSL
    recipient of the fact that the FBI has sought or obtained access to
    the requested information, may be modified or set aside, upon a
    petition filed by the NSL recipient, id. § 3511(b)(1), if the district
    court “finds that there is no reason to believe that disclosure may
    endanger the national security of the United States” or cause other of
    the enumerated harms (worded slightly differently from subsection
    2709(c)(1)), see id. § 3511(b)(2), (3).8 The nondisclosure requirement
    
    18 U.S.C.A. § 2709
    (c) (West Supp. 2008).
    The only change made by the Additional Reauthorization Act was
    to clarify in subdivision (4) of subsection 2709(c) that the recipient
    of an NSL need not notify the FBI of “the identity of an attorney to
    whom disclosure was made or will be made to obtain legal advice or
    legal assistance with respect to the request under subsection (a),”
    
    id.,
     while the original version of subdivision (4) had stated that “in
    no circumstance shall a person be required to inform the Director or
    such designee that the person intends to consult an attorney to obtain
    legal advice or legal assistance.”

    Subsection 3511(b)(2) applies to petitions filed within one year
    of the issuance of an NSL.        A companion provision, subsection
    3511(b)(3), using identical terms, applies to petitions filed more

    further provides that if the Attorney General or senior governmental
    officials certify that disclosure may endanger the national security
    or interfere with diplomatic relations, such certification shall be
    treated as “conclusive” unless the court finds that the certification
    was made “in bad faith.”

    As amended by the Additional Reauthorization Act, section 3511
    provides:
    (a) The recipient of a request for records, a report, or
    other information under section 2709(b) of this title,
    section 626(a) or (b) or 627(a) of the Fair Credit Reporting
    Act, section 1114(a)(5)(A) of the Right to Financial Privacy
    Act, or section 802(a) of the National Security Act of 1947
    may, in the United States district court for the district in
    which that person or entity does business or resides,
    petition for an order modifying or setting aside the
    request. The court may modify or set aside the request if
    compliance would be unreasonable, oppressive, or otherwise
    unlawful.
    (b)(1) The recipient of a request for records, a report,
    or other information under section 2709(b) of this title,
    section 626(a) or (b) or 627(a) of the Fair Credit Reporting
    Act, section 1114(a)(5)(A) of the Right to Financial Privacy
    Act, or section 802(a) of the National Security Act of 1947,
    may petition any court described in subsection (a) for an
    order modifying or setting aside a nondisclosure requirement
    imposed in connection with such a request.
    (2) If the petition is filed within one year of the
    request for records, a report, or other information under
    section 2709(b) of this title, section 626(a) or (b) or
    627(a) of the Fair Credit Reporting Act, section
    1114(a)(5)(A) of the Right to Financial Privacy Act, or
    section 802(a) of the National Security Act of 1947, the
    -13-
    court may modify or set aside such a nondisclosure
    requirement if it finds that there is no reason to believe
    that disclosure may endanger the national security of the
    United States, interfere with a criminal, counterterrorism,
    or   counterintelligence   investigation,   interfere  with
    diplomatic relations, or endanger the life or physical
    safety of any person. If, at the time of the petition, the
    Attorney General, Deputy Attorney General, an Assistant
    Attorney General, or the Director of the Federal Bureau of
    Investigation, or in the case of a request by a department,
    agency, or instrumentality of the Federal Government other
    than the Department of Justice, the head or deputy head of
    such department, agency, or instrumentality, certifies that
    disclosure may endanger the national security of the United
    States or interfere with diplomatic relations, such
    certification shall be treated as conclusive unless the
    court finds that the certification was made in bad faith.
    (3) If the petition is filed one year or more after the
    request for records, a report, or other information under
    section 2709(b) of this title, section 626(a) or (b) or
    627(a) of the Fair Credit Reporting Act, section
    1114(a)(5)(A) of the Right to Financial Privacy Act, or
    section 802(a) of the National Security Act of 1947, the
    Attorney General, Deputy Attorney General, an Assistant
    Attorney General, or the Director of the Federal Bureau of
    Investigation, or his designee in a position not lower than
    Deputy Assistant Director at Bureau headquarters or a
    Special Agent in Charge in a Bureau field office designated
    by the Director, or in the case of a request by a
    department, agency, or instrumentality of the Federal
    Government other than the Federal Bureau of Investigation,
    the head or deputy head of such department, agency, or
    instrumentality, within ninety days of the filing of the
    petition,   shall   either   terminate   the   nondisclosure
    requirement or re-certify that disclosure may result in a
    danger to the national security of the United States,
    interference   with   a   criminal,   counterterrorism,   or
    counterintelligence    investigation,    interference   with
    diplomatic relations, or danger to the life or physical
    safety of any person. In the event of re-certification, the
    court may modify or set aside such a nondisclosure
    requirement if it finds that there is no reason to believe
    -14-
    that disclosure may endanger the national security of the
    United States, interfere with a criminal, counterterrorism,
    or   counterintelligence   investigation,   interfere   with
    diplomatic relations, or endanger the life or physical
    safety of any person. If the recertification that disclosure
    may endanger the national security of the United States or
    interfere with diplomatic relations is made by the Attorney
    General, Deputy Attorney General, an Assistant Attorney
    General, or the Director of the Federal Bureau of
    Investigation, such certification shall be treated as
    conclusive unless the court finds that the recertification
    was made in bad faith. If the court denies a petition for an
    order modifying or setting aside a nondisclosure requirement
    under this paragraph, the recipient shall be precluded for
    a period of one year from filing another petition to modify
    or set aside such nondisclosure requirement.
    (c) In the case of a failure to comply with a request for
    records, a report, or other information made to any person
    or entity under section 2709(b) of this title, section
    626(a) or (b) or 627(a) of the Fair Credit Reporting Act,
    section 1114(a)(5)(A) of the Right to Financial Privacy Act,
    or section 802(a) of the National Security Act of 1947, the
    Attorney General may invoke the aid of any district court of
    the United States within the jurisdiction in which the
    investigation is carried on or the person or entity resides,
    carries on business, or may be found, to compel compliance
    with the request. The court may issue an order requiring the
    person or entity to comply with the request. Any failure to
    obey the order of the court may be punished by the court as
    contempt thereof. Any process under this section may be
    served in any judicial district in which the person or
    entity may be found.
    (d) In all proceedings under this section, subject to any
    right to an open hearing in a contempt proceeding, the court
    must close any hearing to the extent necessary to prevent an
    unauthorized disclosure of a request for records, a report,
    or other information made to any person or entity under
    section 2709(b) of this title, section 626(a) or (b) or
    627(a) of the Fair Credit Reporting Act, section
    1114(a)(5)(A) of the Right to Financial Privacy Act, or
    section 802(a) of the National Security Act of 1947.

    The first appeal. On the Government’s appeals in Doe I and Doe
    CT, this Court remanded Doe I for further consideration in light of
    the amendments to the NSL statutes, and dismissed Doe CT as moot in
    light of the Government’s withdrawal of its objection to disclosure of
    the identity of the NSL recipient in that case. See Doe v. Gonzales,
    
    449 F.3d 415
    , 421 (2d Cir. 2006).
    Withdrawal of the NSL. On November 7, 2006, the Government
    informed the District Court in the pending case that it was no longer
    seeking to enforce the request for information contained in the NSL
    that had been sent to John Doe with respect to information from John
    Doe, Inc. See Doe II, 
    500 F. Supp. 2d at
    386 n.3.
    The District Court’s second decision. On September 6, 2007, the
    District Court issued its second opinion, ruling, on cross-motions for
    Petitions, filings, records, orders, and subpoenas must also
    be kept under seal to the extent and as long as necessary to
    prevent the unauthorized disclosure of a request for
    records, a report, or other information made to any person
    or entity under section 2709(b) of this title, section
    626(a) or (b) or 627(a) of the Fair Credit Reporting Act,
    section 1114(a)(5)(A) of the Right to Financial Privacy Act,
    or section 802(a) of the National Security Act of 1947.
    (e) In all proceedings under this section, the court
    shall, upon request of the government, review ex parte and
    in camera any government submission or portions thereof,
    which may include classified information.
    
    18 U.S.C.A. § 3511
     (West Supp. 2008).
    -16-
    summary judgment, that, despite the amendments to the NSL statutes,
    subsections 2709(c) and 3511(b) are facially unconstitutional, see 
    id. at 387
    , and that the Defendants-Appellants are enjoined from issuing
    NSLs under section 2709 and enforcing the provisions of subsections
    2709(c) and 3511(b), see 
    id. at 425-26
    .10 The Court stayed enforcement
    of its judgment pending appeal. See 
    id. at 426
    .
    In a careful and comprehensive opinion the District Court viewed
    the “fundamental question” to be “the extent of the authority that the
    First Amendment allows the government to exercise in keeping its use
    of NSLs secret, insofar as such secrecy inhibits freedom of speech.”
    
    Id. at 395
    .    The   Court   began     its   analysis     by   reaffirming    its
    conclusion from Doe I that the nondisclosure requirement of subsection
    2709(c), despite amendment, remains “a prior restraint and a content-
    based        restriction    on   speech,”    
    id. at 397
    ,    subject    to   “strict
    scrutiny,” 
    id. at 398
    .           The analysis then proceeded in several steps.
    First, the Court, applying strict scrutiny and acknowledging that
    national security is a compelling state interest, ruled that the
    nondisclosure        provisions     invested   executive        officials   with   broad
    10
    The   Court   rejected  the   Plaintiffs’   challenge   to   the
    constitutionality of the provisions authorizing courtroom closure for
    proceedings under section 3511, see 
    18 U.S.C. § 3511
    (d), and requiring
    a district court, upon the Government’s request, to review ex parte
    and in camera Government submissions that may include classified
    information, see 
    id.
     § 3511(e). See Doe II, 
    500 F. Supp. 2d at 422-24
    .
    The Plaintiffs-Appellees have not taken a cross-appeal to challenge
    these rulings.
    -17-
    discretion to censor speech but failed to provide necessary procedural
    safeguards. See 
    id. at 399-406
    . Specifically, the Court, applying the
    teaching of Freedman v. Maryland, 
    380 U.S. 51
     (1965), a motion picture
    licensing case, held that the nondisclosure provisions impermissibly
    placed the burden of initiating judicial review on the NSL recipient.
    See Doe II, 
    500 F. Supp. 2d at 405-06
    .            However, the Court rejected
    the Plaintiffs’ argument that the nondisclosure provisions invested
    executive officers with unbridled discretion to suppress speech in
    violation of Shuttlesworth v. City of Birmingham, 
    394 U.S. 147
     (1969).
    See Doe II, 
    500 F. Supp. 2d at 406-09
    .
    Second, the Court, relying on Dickerson v. United States, 
    530 U.S. 428
    , 437 (2000), and City of Boerne v. Flores, 
    521 U.S. 507
    ,
    535-36 (1997), ruled that subsection 3511(b) violates the First
    Amendment   and   the   principle   of    separation    of   powers   because   it
    prescribes a judicial review procedure and a standard of review
    inconsistent with First Amendment strict scrutiny requirements. Doe
    II, 
    500 F. Supp. 2d at 411-19
    .
    Finally,     the   Court   ruled    that   the   nondisclosure   provisions
    violate the First Amendment because they permit the FBI to issue
    nondisclosure orders that are not narrowly tailored in scope or
    duration. See 
    id. at 419-22
    .        Specifically, the Court noted that the
    nondisclosure provisions close off a broad spectrum of speech at the
    core of the First Amendment--political criticism--and that the statute
    -18-
    contains “no requirement that the government act affirmatively and
    promptly to terminate the nondisclosure order” if the need for secrecy
    dissipates.    See 
    id. at 422
    .
    The Court then ruled that the unconstitutional portions of the
    statute were not severable from the remainder of the statute. See 
    id. at 424-25
    .    Specifically, the Court reasoned that because secrecy was
    integral to the statutory scheme that Congress envisioned, it would
    not have wanted the NSL statute to operate without the nondisclosure
    provisions.    It therefore invalidated section 2709 in its entirety.
    See 
    id. at 425
    .
    Discussion
    The validity of the NSL issued to John Doe, Inc., is no longer at
    issue because the Government has withdrawn it, but the prohibition on
    disclosing receipt of the NSL remains. We therefore consider only the
    Government’s challenges to the District Court’s rulings with respect
    to the nondisclosure requirement, although to the extent that the
    nondisclosure requirement encounters valid constitutional objections,
    we will consider the provisions authorizing issuance of NSLs in
    connection with the issue of severance.
    I. Applicable Principles
    The First Amendment principles relevant to the District Court’s
    rulings are well established, although their application to the
    statutory provisions at issue requires careful consideration.        A
    -19-
    judicial order “forbidding certain communications when issued in
    advance    of    the   time   that   such   communications      are   to    occur”   is
    generally regarded as a “prior restraint,” Alexander v. United States,
    
    509 U.S. 544
    , 550 (1993) (emphasis and internal quotation marks
    omitted),       and    is   “the   most   serious   and   the     least     tolerable
    infringement on First Amendment rights,” Nebraska Press Ass’n v.
    Stuart, 
    427 U.S. 539
    , 559 (1976).           “Any prior restraint on expression
    comes to [a court] with a heavy presumption against its constitutional
    validity,” Organization for a Better Austin v. Keefe, 
    402 U.S. 415
    ,
    419 (1971) (internal quotation marks omitted), and “carries a heavy
    burden of showing justification,” 
    id.
                A content-based restriction is
    subject to review under the standard of strict scrutiny, requiring a
    showing that the restriction is “narrowly tailored to promote a
    compelling       Government        interest.”    United    States      v.     Playboy
    Entertainment Group, Inc., 
    529 U.S. 803
    , 813 (2000).
    Where expression is conditioned on governmental permission, such
    as a licensing system for movies, the First Amendment generally
    requires     procedural       protections   to   guard    against     impermissible
    censorship. See Freedman, 
    380 U.S. at 58
    . Freedman identified three
    procedural requirements: (1) any restraint imposed prior to judicial
    review must be limited to “a specified brief period”; (2) any further
    restraint prior to a final judicial determination must be limited to
    “the shortest fixed period compatible with sound judicial resolution”;
    -20-
    and (3) the burden of going to court to suppress speech and the burden
    of proof in court must be placed on the government. See 
    id. at 58-59
    (numbering and ordering follows Supreme Court’s discussion of Freedman
    in FW/PBS, Inc. v. City of Dallas, 
    493 U.S. 215
    , 227 (1990)); Thomas
    v. Chicago Park District, 
    534 U.S. 316
    , 321 (2002).
    Once     constitutional        standards   have     been    authoritatively
    enunciated,      Congress   may   not    legislatively   supercede    them.     See
    Dickerson, 
    530 U.S. at 437
    .             “When the political branches of the
    Government act against the background of a judicial interpretation of
    the Constitution already issued, it must be understood that in later
    cases and controversies the Court will treat its precedents with the
    respect due them under settled principles, including stare decisis,
    and contrary expectations must be disappointed.” City of Boerne, 
    521 U.S. at 536
    .
    The national security context in which NSLs are authorized
    imposes on courts a significant obligation to defer to judgments of
    Executive     Branch    officials.      “[C]ourts   traditionally     have    been
    reluctant to intrude upon the authority of the Executive in . . .
    national security affairs,” Department of Navy v. Egan, 
    484 U.S. 518
    ,
    530 (1988), and the Supreme Court has acknowledged that terrorism
    might provide the basis for arguments “for heightened deference to the
    judgments   of    the   political    branches   with   respect   to   matters    of
    national security,” Zadvydas v. Davis, 
    533 U.S. 678
    , 696 (2001).
    -21-
    The   last   set   of   principles    implicated   by   the   Plaintiffs’
    constitutional challenges concerns the somewhat related issues of
    judicial interpretation of unclear statutes, judicial revision of
    constitutionally    defective    statutes,    and   judicial   severance   of
    constitutionally invalid provisions from otherwise valid provisions.
    It is well established that courts should resolve ambiguities in
    statutes in a manner that avoids substantial constitutional issues.
    See Crowell v. Benson, 
    285 U.S. 22
    , 62 (1932); Ashwander v. Tennessee
    Valley Authority, 
    297 U.S. 288
    , 348 (1936) (Brandeis, J., concurring).
    Less clear is the authority of courts to revise a statute to
    overcome a constitutional defect.         Of course, it is the province of
    the Legislative Branch to legislate. But in limited circumstances the
    Supreme Court has undertaken to fill in a statutory gap arising from
    the invalidation of a portion of a statute.             The Court did so in
    United States v. Thirty-Seven Photographs, 
    402 U.S. 363
     (1971).
    Considering a statute authorizing customs agents to seize obscene
    materials, see 
    19 U.S.C. § 1305
    (a), the Court noted that the statute
    lacked time limits on initiating and completing judicial proceedings,
    see Thirty-Seven Photographs, 
    402 U.S. at 368
    , limits constitutionally
    required by Freedman, 
    380 U.S. at 58
    , Teitel Film Corp. v. Cusack, 
    390 U.S. 139
    , 141 (1968), and Blount v. Rizzi, 
    400 U.S. 410
    , 417 (1971).
    After ruling that “the reading into [subsection 1305(a)] of the time
    limits required by Freedman is fully consistent with its legislative
    -22-
    purpose,” Thirty-Seven Photographs, 
    402 U.S. at 370
    , the Court imposed
    a 14-day limit on the initiation of judicial proceedings and a 60-day
    limit on their completion, see 
    id. at 373-74
    .11
    More recently, the Court encountered another statutory revision
    issue in United States v. Booker, 
    543 U.S. 220
     (2005).            After ruling
    in its remedy opinion that the Court’s constitutionally required
    invalidation of the mandatory nature of the Sentencing Guidelines
    required   excision   of   
    18 U.S.C. § 3742
    (e),   the   judicial   review
    provision of the Sentencing Reform Act, see Booker, 543 U.S. at 258-
    60, the Court considered whether to “infer,” id. at 260, primarily
    from other statutes, a judicially created standard of review.               The
    Court did so, selecting, based on “related statutory language, the
    structure of the statute, and the sound administration of justice,”
    id. at 260-61 (internal quotation marks omitted), “a reasonableness
    standard of review,” id. at 262 (internal quotation marks omitted).
    Our Court has also revised statutory provisions to avoid or
    overcome constitutional defects.         In Lee v. Thornton, 
    538 F.2d 27
     (2d
    Cir. 1976), after invalidating provisions for seizure of vehicles for
    11
    The Court explained that it had lacked the authority to impose
    missing time limits in state statutes invalidated in Freedman and
    Teitel, see Thirty-Seven Photographs, 
    402 U.S. at 369
    , and could not
    have remedied the absence of constitutionally required judicial review
    procedures in Blount because the statute had been enacted after the
    relevant Executive Branch officer had explicitly opposed inclusion of
    a judicial review provision, 
    id. at 369-70
    .
    -23-
    lack of procedural due process, see id. at 32-33, we required action
    on petitions for mitigation or remission within 24 hours and required
    a probable cause hearing within 72 hours, see id. at 33.                In United
    States v. Monsanto, 
    924 F.2d 1186
     (2d Cir. 1991) (in banc), we
    inserted into a post-indictment hearing procedure a requirement for
    reconsideration of probable cause in connection with a restraint on
    pretrial disposition of assets. See 
    id. at 1198-1202
    .             See generally
    Eubanks   v.   Wilkinson,     
    937 F.2d 1118
    ,   1122-25    (6th    Cir.   1991)
    (collecting cases where courts have either revised or declined to
    revise statutory language).
    Closely related to the issue of whether a court should revise a
    statute to avoid or overcome a constitutional defect is the issue of
    whether   to   sever   the   unconstitutional      portion   of   a   statute   or
    invalidate an entire statute or even an entire statutory scheme.                In
    general, the choice, as stated by the Supreme Court, depends on
    whether “the legislature [would] have preferred what is left of its
    statute to no statute at all.” Ayotte v. Planned Parenthood of
    Northern New England, 
    546 U.S. 320
    , 330 (2006).              The Court has also
    cautioned that “[u]nless it is evident that the Legislature would not
    have    enacted   those      provisions    which   are   within       its    power,
    independently of that which is not, the invalid part may be dropped if
    what is left is fully operative as a law.” Buckley v. Valeo, 
    424 U.S. 1
    , 108 (1976) (internal quotation marks omitted).
    -24-
    The Court recently applied this approach to severance in Booker.
    After ruling that the mandatory nature of the Sentencing Guidelines
    was unconstitutional, the Court had to consider whether to invalidate
    the entire Guidelines system or to excise two provisions, 
    18 U.S.C. §§ 3553
    (b)(1) and 3742(e), and leave the remainder of the Sentencing
    Reform Act intact. See Booker, 543 U.S. at 258. Concluding that
    Congress would have wanted to maintain the Sentencing Guidelines even
    if they were advisory, rather than mandatory, the Court elected to
    excise subsections 3553(b)(1) and 3742(e). See id.
    II. The Parties’ Contentions
    With these principles in mind, we turn to the parties’ basic
    contentions.       From the Plaintiffs’ standpoint, the nondisclosure
    requirement of subsection 2709(c) presents a straightforward content-
    based prior restraint that must be tested against all the substantive
    and   procedural    limitations   applicable   to   such   an   impairment   of
    expression. In their view, the nondisclosure requirement is content-
    based because it proscribes disclosure of the entire category of
    speech concerning the fact and details of the issuance of an NSL, see
    Consolidated Edison Co. of New York v. Public Service Commission, 
    447 U.S. 530
    , 537 (1980), and it is a prior restraint in the literal sense
    that it is imposed before an NSL recipient has an opportunity to
    speak, see Alexander, 
    509 U.S. at 550
    .          From these premises, the
    Plaintiffs conclude that subsection 2709(c) is unconstitutional under
    -25-
    strict     scrutiny       review     because        it     prohibits      disclosure     in
    circumstances not narrowly tailored to a compelling governmental
    interest and operates as a licensing scheme without the procedural
    requirement of placing on the Government the burden of initiating
    judicial review and sustaining a burden of proof. The Plaintiffs also
    challenge subsection 3511(b) on the grounds that (1) the judicial
    review provisions do not require the Government to initiate judicial
    review and to sustain a burden of proof and (2) certification of
    certain risks by senior governmental officials is entitled to a
    conclusive      presumption        (absent    bad     faith).         These   aspects   of
    subsection 3511(b) are alleged to violate First Amendment procedural
    standards and the separation of powers.
    The       Government     responds        that,       to    whatever      extent    the
    nondisclosure requirement can be considered a content-based prior
    restraint, it is subject to less rigorous scrutiny than those imposed
    on more typical First Amendment claimants who wish to speak or parade
    in public places, distribute literature, or exhibit movies.                             The
    Government points out that the nondisclosure requirement arises not to
    suppress a pre-existing desire to speak, but only as a result of
    governmental interaction with an NSL recipient.                      In the Government’s
    view,    the    nondisclosure       requirement          survives    a   First   Amendment
    challenge      on   the     same     rationale      that       has   permitted    secrecy
    requirements to be imposed on witnesses before grand juries, see

    III. The Interpretation of the NSL Statutes
    In       assessing   these    contentions,          we   need    to    interpret    the
    nondisclosure requirements before ruling on their constitutionality.
    As set forth above in notes 7 and 9, subsection 2709(c) specifies what
    senior      FBI      officials    must    certify    to     trigger     the   nondisclosure
    requirement, and subsection 3511(b) specifies, in similar but not
    identical language, what a district court must find in order to modify
    or set aside such a requirement.               Senior FBI officials must certify
    that in the absence of a nondisclosure requirement “there may result
    a danger to the national security of the United States, interference
    with        a     criminal,       counterterrorism,             or     counterintelligence
    investigation, interference with diplomatic relations, or danger to
    the life or physical safety of any person.” 
    18 U.S.C. § 2709
    (c)(1).
    Upon challenge by an NSL recipient, a district court may modify or set
    aside a nondisclosure requirement “if it finds that there is no reason
    -27-
    to believe that disclosure may endanger the national security of the
    United   States,   interfere   with    a     criminal,   counterterrorism,    or
    counterintelligence      investigation,        interfere    with       diplomatic
    relations, or endanger the life or physical safety of any person.” 
    Id.
    § 3511(b)(2).
    These provisions present three issues for interpretation: (1)
    what is the scope of the enumerated harms? (2) what justifies a
    nondisclosure requirement? and (3) which side has the burden of proof?
    The enumerated harms. The first issue concerns the scope of the
    language identifying the enumerated harms.           It is the risk of these
    harms that senior FBI officials must certify in order to impose the
    nondisclosure requirement.      These harms are “danger to the national
    security   of   the   United   States,     interference    with    a   criminal,
    counterterrorism, or counterintelligence investigation, interference
    with diplomatic relations, or danger to the life or physical safety of
    any person.” 
    18 U.S.C. § 2709
    (c)(1).          The last phrase is particularly
    troublesome. It could extend the Government’s power to impose secrecy
    to a broad range of information relevant to such matters as ordinary
    tortious conduct, based on the risk of “danger to the physical safety
    of any person.”       A secrecy requirement of such broad scope would
    present highly problematic First Amendment issues.                However, this
    potential reach of the nondisclosure requirement can be reined in if
    all the enumerated harms are keyed to the same standard that governs
    -28-
    information     sought   by   an   NSL,    i.e.,    “relevant    to   an   authorized
    investigation     to     protect    against        international      terrorism      or
    clandestine intelligence activities.” 
    Id.
     § 2709(b)(1), (2).
    At oral argument, the Government wisely urged us to avoid this
    problem by construing the scope of the enumerated harms in light of
    the purposes for which an NSL is issued.             We readily accept that view
    of the nondisclosure requirement, thereby at least narrowing, though
    not eliminating, the First Amendment issues. Thus, we will adjudicate
    the constitutionality of the nondisclosure requirement in subsection
    2709(c) by construing this requirement to apply only when senior FBI
    officials certify that disclosure may result in an enumerated harm
    that is related to “an authorized investigation to protect against
    international terrorism or clandestine intelligence activities.” Id.
    The required showing. The second issue concerns what must be
    shown to maintain a nondisclosure requirement upon judicial review.
    A district court, considering a challenge filed within one year of the
    issuance   of    an    NSL,   is   authorized      to   modify   or   set    aside    a
    nondisclosure requirement “if it finds that there is no reason to
    believe that disclosure may” risk one of the enumerated harms. 
    18 U.S.C. § 3511
    (b)(2).          At oral argument, the Government took the
    position that “reason” in the quoted phrase means “good reason.”                     We
    accept this common-sense understanding of subsection 3511(b)(2). Cf.
    McGehee v. Casey, 
    718 F.2d 1137
    , 1148 (D.C. Cir. 1983) (“[C]ourts
    -29-
    . . . must . . . satisfy themselves . . . that the CIA in fact had
    good reason to classify, and therefore censor, the materials at
    issue.”).         We take a similar view of the identical language in
    subsection 3511(b)(3), governing a challenge filed more than one year
    after issuance of an NSL.
    Moreover, a reason will not qualify as “good” if it surmounts
    only   a   standard    of    frivolousness.           We    understand   the   statutory
    requirement of a finding that an enumerated harm “may result” to mean
    more than a conceivable possibility.              The upholding of nondisclosure
    does   not   require    the       certainty,    or    even    the   imminence    of,    an
    enumerated harm, but some reasonable likelihood must be shown.                         The
    Government acknowledges that “while the ‘reason to believe’ standard
    in   subsection      3511(b)      unquestionably       contemplates      a   deferential
    standard     of    review,   in    no   way    does    it    foreclose   a   court   from
    evaluating the reasonableness of the FBI’s judgments.” Reply Br. for
    Appellants at 9.
    The burden of proof. The third issue concerns the burden of proof
    applicable to the finding contemplated by subsection 3511(b)(2). Does
    this provision mean that, in order to have a district court modify or
    set aside a nondisclosure requirement, an ECSP must persuade a court
    that there is no good reason to believe that disclosure may risk one
    of the enumerated harms, or that, in order to maintain a nondisclosure
    requirement, the Government must persuade a court that there is a good
    -30-
    reason to believe that disclosure may risk one of the enumerated
    harms?    As the Government acknowledged at oral argument, subsection
    3511(b) is silent as to the burden of proof.                      The Government also
    acknowledged    at     oral    argument    that         these   provisions     should    be
    understood to place on the Government the burden to persuade a
    district court that there is a good reason to believe that disclosure
    may risk one of the enumerated harms, and that a district court, in
    order to modify or set aside a nondisclosure order, must find that
    such a good reason exists, rather than find the negative, i.e., that
    no good reason exists to believe that disclosure may risk one of the
    enumerated harms.       We agree.
    Under the principles outlined above, we are satisfied that we may
    accept the Government’s concessions on all three matters of statutory
    interpretation       without    trenching          on    Congress’s    prerogative      to
    legislate.      See    Thirty-Seven       Photographs,          
    402 U.S. at 368-70
    ;
    Monsanto, 
    924 F.2d at 1198-1202
    ; Lee, 
    538 F.2d at 33
    .                              We will
    therefore construe subsection 2709(c)(1) to mean that the enumerated
    harms must be related to “an authorized investigation to protect
    against    international         terrorism         or      clandestine       intelligence
    activities,” 
    18 U.S.C. § 2709
    (b)(1), (2), and construe subsections
    3511(b)(2) and (3) to place on the Government the burden to persuade
    a   district   court    that    there     is   a    good    reason    to     believe   that
    disclosure may result in one of the enumerated harms, and to mean that
    -31-
    a district court, in order to modify or set aside a nondisclosure
    order, must find that such a good reason exists.
    IV. Constitutionality of the NSL Statutes
    (a) Basic approach. Turning to the First Amendment issues with
    respect to the NSL statutes as thus construed, we believe that the
    proper path to decision lies between the broad positions asserted by
    the parties.   Although the nondisclosure requirement is in some sense
    a prior restraint, as urged by the Plaintiffs, it is not a typical
    example of such a restriction for it is not a restraint imposed on
    those who customarily wish to exercise rights of free expression, such
    as speakers in public fora, distributors of literature, or exhibitors
    of movies. Cf. Seattle Times, 
    467 U.S. at 33
     (noting that prohibition
    on disclosure of material obtained through pretrial discovery was “not
    the kind of classic prior restraint that requires exacting First
    Amendment scrutiny”).12   And although the nondisclosure requirement is
    triggered by the content of a category of information, that category,
    consisting of the fact of receipt of an NSL and some related details,
    is far more limited than the broad categories of information that have
    12
    We   note   that  none    of  the   decisions   discussing   the
    appropriateness or limits of grand jury secrecy has referred to a
    nondisclosure requirement in that context as a prior restraint. See
    also McGehee, 
    718 F.2d at 1147
     (noting that neither the CIA’s
    classification of portions of a former employee’s proposed book as top
    secret nor a court order rejecting a First Amendment challenge
    “constitutes a prior restraint in the traditional sense”).
    -32-
    been at issue with respect to typical content-based restrictions. Cf.
    Consolidated Edison, 
    447 U.S. at 537
    .
    On the other hand, we do not accept the Government’s contentions
    that the nondisclosure requirement can be considered to satisfy First
    Amendment standards based on analogies to secrecy rules applicable to
    grand   juries,     judicial    misconduct         proceedings,     and   certain
    interactions between individuals and governmental entities.                     The
    justification for grand jury secrecy inheres in the nature of the
    proceedings.    As the Supreme Court has noted, such secrecy serves
    several interests common to most such proceedings, including enhancing
    the willingness of witnesses to come forward, promoting truthful
    testimony, lessening the risk of flight or attempts to influence grand
    jurors by those about to be indicted, and avoiding public ridicule of
    those whom the grand jury declines to indict. See Douglas Oil Co. of
    California v. Petrol Stops Northwest, 
    441 U.S. 211
    , 218-19 (1979).
    Although     these   interests   do     not   warrant   a    prohibition    on
    disclosure of a witness’s own testimony after the term of the grand
    jury has ended, see Butterworth v. Smith, 
    494 U.S. 624
    , 630-36 (1990),
    they generally suffice to maintain grand jury secrecy against First
    Amendment claims to divulge information a witness obtained through
    participation in the grand jury process. See Hoffman-Pugh, 
    338 F.3d at 1139-40
    .   Unlike the grand jury proceeding, as to which interests in
    secrecy arise from the nature of the proceeding, the nondisclosure
    -33-
    requirement of subsection 2709(c) is imposed at the demand of the
    Executive Branch under circumstances where secrecy might or might not
    be warranted, depending on the circumstances alleged to justify such
    secrecy.
    The     Government’s    analogy     to    permissible    limitations      on
    disclosures in connection with judicial misconduct proceedings also
    fails to justify the nondisclosure requirement of subsection 2709(c).
    We considered First Amendment challenges to nondisclosure requirements
    imposed with respect to judicial misconduct proceedings in Kamasinski.
    Initially,    we   noted    the   interests    in    confidentiality    in   such
    proceedings    that   the   Supreme    Court   had    identified   in   Landmark
    Communications, Inc. v. Virginia, 
    435 U.S. 829
     (1978). See Kamasinski,
    
    44 F.3d at 110
    . These interests are: “(1) encouraging the filing of
    complaints; (2) protecting judges from unwarranted complaints; (3)
    . . . avoiding premature announcement of groundless complaints; and
    (4) facilitating the work of the commission by giving it flexibility
    to accomplish its mission through voluntary retirement or resignation
    of offending judges.” Id.; see Landmark, 
    435 U.S. at 835-37
    .             Again,
    unlike the context of subsection 2709(c), these considerations inhere
    in the nature of judicial misconduct proceedings.            In Kamasinski, we
    ruled that disclosure of the substance of an individual’s complaint
    could not be prohibited, see 
    44 F.3d at 110
    , but that the First
    Amendment permitted prohibition of disclosure of the fact that an
    -34-
    individual had filed a complaint or had testified, and of information
    gained through interaction with the misconduct commission, see 
    id. at 111
    .    We noted, however, that these prohibitions were justified in
    part by their cessation once the commission had determined whether or
    not there was probable cause that judicial misconduct had occurred.
    See 
    id. at 112
    .    That temporal limitation, important in the balance of
    governmental   versus   free    speech     interests,     is   absent   from   the
    nondisclosure requirement of subsection 2709(c).
    The Government’s analogy to certain interactions between an
    individual   and   governmental     entities       is   also   unavailing.     The
    Government seeks to enlist cases involving classification of former
    CIA employees’ information as top secret, see United States v. Snepp,
    
    897 F.2d 138
     (4th Cir. 1990), and United States v. Marchetti, 
    466 F.2d 1309
     (4th Cir. 1972), and a prohibition on disclosure of information
    obtained by a litigant through court-ordered discovery, see Seattle
    Times, 
    467 U.S. 20
    .      We fail to appreciate the analogy between the
    individuals or the entity seeking disclosure in those cases and John
    Doe, Inc., who had no interaction with the Government until the
    Government imposed its nondisclosure requirement upon it.
    The nondisclosure requirement of subsection 2709(c) is not a
    typical   prior    restraint   or   a    typical    content-based    restriction
    warranting the most rigorous First Amendment scrutiny.              On the other
    hand, the Government’s analogies to nondisclosure prohibitions in
    -35-
    other contexts do not persuade us to use a significantly diminished
    standard of review.      In any event, John Doe, Inc., has been restrained
    from publicly expressing a category of information, albeit a narrow
    one, and that information is relevant to intended criticism of a
    governmental activity. See Gentile v. State Bar of Nevada, 
    501 U.S. 1030
    , 1034 (1991) (“There is no question that speech critical of the
    exercise of the State’s power lies at the very center of the First
    Amendment.”); Landmark, 
    435 U.S. at 838
     (“Whatever differences may
    exist      about   interpretations   of   the   First   Amendment,   there   is
    practically universal agreement that a major purpose of that Amendment
    was   to    protect   the   free   discussion   of   governmental    affairs.”)
    (internal quotation marks omitted).
    The panel is not in agreement as to whether, in this context, we
    should examine subsection 2709(c) under a standard of traditional
    strict scrutiny or under a standard that, in view of the context, is
    not quite as “exacting” a form of strict scrutiny, Seattle Times, 
    467 U.S. at 33
    .        Ultimately, this disagreement has no bearing on our
    disposition because, as we discuss below, the only two limitations on
    NSL procedures required by First Amendment procedural standards would
    be required under either degree of scrutiny.               We note that, for
    purposes of the litigation in this Court, the Government has conceded
    that strict scrutiny is the applicable standard.
    (b) Strict scrutiny. Under strict scrutiny review, the Government
    -36-
    must demonstrate that the nondisclosure requirement is “narrowly
    tailored    to   promote    a     compelling         Government         interest,”    Playboy
    Entertainment,     
    529 U.S. at 813
    ,     and    that    there      are   no    “less
    restrictive alternatives [that] would be at least as effective in
    achieving the legitimate purpose that the statute was enacted to
    serve,” Reno v. ACLU, 
    521 U.S. 844
    , 874 (1997).                               Since “[i]t is
    obvious    and   unarguable       that       no     governmental        interest     is   more
    compelling than the security of the Nation,” Haig v. Agee, 
    453 U.S. 280
    , 307 (1981) (internal quotation marks omitted), the principal
    strict     scrutiny    issue      turns      on     whether       the    narrow     tailoring
    requirement is met, and this issue, as the District Court observed,
    essentially      concerns      the        process     by    which       the    nondisclosure
    requirement is imposed and tested, see Doe II, 
    500 F. Supp. 2d at 399
    .
    With subsections 2709(c) and 3511(b) interpreted as set forth
    above, see Part III, 
    supra,
     two aspects of that process remain
    principally at issue: the absence of a requirement that the Government
    initiate    judicial     review      of     the     lawfulness      of    a    nondisclosure
    requirement and the degree of deference a district court is obliged to
    accord to the certification of senior governmental officials in
    ordering nondisclosure.13
    13
    The Plaintiffs challenged the nondisclosure requirement on the
    ground that the discretion vested in senior FBI officials in
    determining whether to issue an NSL was unconstitutionally broad, see
    Shuttlesworth, 
    394 U.S. 147
    . The District Court rejected this claim.
    -37-
    (i) Absence of requirement that the Government initiate judicial
    review. The Plaintiffs alleged, and the District Court agreed, that
    the third Freedman procedural requirement applies to the NSL statutes,
    requiring the Government to initiate judicial review of its imposition
    of a nondisclosure requirement. See Freedman, 
    380 U.S. at 58-59
    .
    The Government advances several arguments why the third Freedman
    safeguard should not apply to judicial review of the nondisclosure
    requirement.   First, the Government contends that it would be unduly
    burdened if it had to initiate a lawsuit to enforce the nondisclosure
    requirement in the more than 40,000 NSL requests that were issued in
    2005 alone, according to the 2007 report of the Inspector General of
    the Department of Justice (“OIG Report”).14 See Doe II, 
    500 F. Supp. 2d at 390
    . Related to this argument is the point, advanced in the
    Government’s brief to distinguish Freedman, that “there is no reason
    See Doe II, 
    500 F. Supp. 2d at 406-09
    . In this Court, the Plaintiffs
    renewed this argument only in footnotes. Under the circumstances, we
    deem the issue forfeited on appeal. See United States v. Restrepo, 
    986 F.2d 1462
    , 1463 (2d Cir. 1993) (“We do not consider an argument
    mentioned only in a footnote to be adequately raised or preserved for
    appellate review.”).

    to believe that most recipients of NSLs wish to disclose that fact to
    anyone.” Br. for Appellants at 33.
    Instead of determining whether, as the Government contends, a
    burden of initiating litigation can prevent application of the third
    Freedman procedural safeguard, we consider an available means of
    minimizing that burden, use of which would substantially avoid the
    Government’s argument. The Government could inform each NSL recipient
    that it should give the Government prompt notice, perhaps within ten
    days,    in    the       event   that   the    recipient       wishes    to   contest   the
    nondisclosure        requirement.          Upon      receipt    of     such   notice,   the
    Government could be accorded a limited time, perhaps 30 days, to
    initiate a judicial review proceeding to maintain the nondisclosure
    requirement, and the proceeding would have to be concluded within a
    prescribed time, perhaps 60 days.                 In accordance with the first and
    second Freedman safeguards, the NSL could inform the recipient that
    the nondisclosure requirement would remain in effect during the entire
    interval      of     the     recipient’s      decision     whether      to    contest   the
    nondisclosure requirement, the Government’s prompt application to a
    court,   and       the     court’s   prompt    adjudication       on    the   merits.   See
    Freedman, 
    380 U.S. at 58
    .               The NSL could also inform the recipient
    that the nondisclosure requirement would remain in effect if the
    recipient declines to give the Government notice of an intent to
    challenge the requirement or, upon a challenge, if the Government
    -39-
    prevails in court.        If the Government is correct that very few NSL
    recipients   have   any    interest   in     challenging   the    nondisclosure
    requirement (perhaps no more than three have done so thus far), this
    “reciprocal notice procedure” would nearly eliminate the Government’s
    burden to initiate litigation (with a corresponding minimal burden on
    NSL recipients to defend numerous lawsuits).         Thus, the Government’s
    litigating burden can be substantially minimized, and the resulting
    slight burden is not a reason for precluding application of the third
    Freedman safeguard.
    The Government’s second argument for not applying Freedman’s
    third safeguard relies on an attempt to analogize the nondisclosure
    requirement in NSLs to nondisclosure requirements imposed in the
    context of pre-existing interaction with a governmental activity.
    Unlike the movies subject to licensing in Freedman, which were created
    independently of governmental activity, the information kept secret by
    an NSL, the Government contends, is “information that the recipient
    learns by (and only through) his participation in the [G]overnment’s
    own investigatory processes.” Br. for Appellants at 31.             Although the
    governmental interaction distinction has validity with respect to the
    litigant obtaining discovery material in Seattle Times and the former
    CIA employees seeking to disclose sensitive material in Marchetti and
    Snepp, we think it has no application to an ECSP with no relevant
    governmental interaction prior to receipt of an NSL.             The recipient’s
    -40-
    “participation” in the investigation is entirely the result of the
    Government’s action. The Government also relies on analogies to
    secrecy       requirements     in   grand   jury    and     judicial   misconduct
    proceedings, analogies we have previously rejected. See Part IV(a),
    supra.
    Third, the Government seeks to avoid Freedman’s third requirement
    on the ground that the risk of administrative error “is significantly
    smaller under [sub]section 2709(c) than under licensing schemes like
    the one in Freedman.” Br. for Appellants at 33.             Although the risk of
    error may be smaller, it remains sufficient to require a judicial
    review procedure that conforms to Freedman.           The OIG Report concluded
    that “‘the FBI used NSLs in violation of applicable NSL statutes,
    Attorney General Guidelines, and internal FBI policies.’” Doe II, 
    500 F. Supp. 2d at 392
     (quoting OIG Report at 124).
    Fourth, the Government points out that the Supreme Court did not
    apply the third Freedman requirement to the licensing scheme that was
    challenged in FW/PBS, which concerned licenses for sexually oriented
    businesses.       However, the distinctions with Freedman noted by the
    Court    in   FW/PBS   point   in   favor   of   applying    the   third   Freedman
    requirement to subsection 2709(c).            First, the Court noted that the
    licensing authority was not “passing judgment on the content of any
    protected speech,” but was performing the “ministerial action” of
    “review[ing] the general qualifications of each license applicant.”
    -41-
    FW/PBS, 
    493 U.S. at 229
    .                Under subsection 2709(c), however, the
    Government is exercising discretion to prohibit disclosure of speech
    on a topic of significant public concern.                     Second, the Court noted
    that the license applicant in FW/PBS had “every incentive” to initiate
    a judicial challenge to a license denial because the license was “the
    key to the applicant’s obtaining and maintaining a business,” 
    id. at 229-30
    ,    a    greater      incentive       than   the   movie      distributor    had   in
    Freedman, “where only one film was censored,” 
    id. at 229
    .                      The typical
    NSL recipient, by contrast, who runs a business that is in no sense
    dependent on revealing the receipt of an NSL, has little if any
    incentive to initiate a court challenge in order to speak publicly
    about such receipt.          FW/PBS does not provide a basis for ignoring the
    third Freedman requirement.
    We acknowledge, however, that the nondisclosure requirement of
    subsection 2709(c) is not facially a licensing scheme of the sort at
    issue in Freedman.        Unlike an exhibitor of movies, John Doe, Inc., did
    not   intend     to    speak    and    was    not   subject    to    any   administrative
    restraint on speaking prior to the Government’s issuance of an NSL.
    Nevertheless, once the NSL arrived, John Doe, Inc., did wish to speak
    publicly       about    it     and    was    prohibited       from     doing   so   by    an
    administrative         order.         Freedman’s     third    requirement      cannot     be
    disregarded simply because subsection 2709(c) does not impose a
    traditional licensing scheme.
    -42-
    The availability of a minimally burdensome reciprocal notice
    procedure for governmental initiation of judicial review and the
    inadequacy of the Government’s attempts to avoid the third Freedman
    safeguard persuade us that this safeguard, normally required where
    strict scrutiny applies, must be observed. Therefore, in the absence
    of Government-initiated judicial review, subsection 3511(b) is not
    narrowly tailored to conform to First Amendment procedural standards.
    We conclude, as did the District Court, see Doe II, 
    500 F. Supp. 2d at 401-06
    , that subsection 3511(b) does not survive either traditional
    strict scrutiny or a slightly less exacting measure of such scrutiny.
    (ii) Deference to administrative discretion.                 The Plaintiffs
    contended, and the District Court agreed, that the judicial review
    contemplated by subsection 3511(b) authorizes a degree of deference to
    the   Executive   Branch    that   is    inconsistent   with   First    Amendment
    standards.     Although acknowledging that “national security is a
    compelling interest justifying nondisclosure in certain situations,”
    
    id. at 418
    , the District Court faulted the review provision in several
    respects.    First, the Court stated that the statute “requires the
    court to blindly credit a finding that there ‘may’ be a reason--
    potentially any conceivable and not patently frivolous reason--for it
    to believe disclosure will result in a certain harm.” 
    Id.
                          Our
    construction   of   the    statute,     however,   avoids   that    concern.   As
    indicated above, see Part III, 
    supra,
     we interpret subsection 3511(b)
    -43-
    to place on the Government the burden to show a “good” reason to
    believe that disclosure may result in an enumerated harm, i.e., a harm
    related   to     “an   authorized      investigation       to   protect      against
    international terrorism or clandestine intelligence activities,” 
    18 U.S.C. § 2709
    (b)(1), (2), and to place on a district court an
    obligation to make the “may result” finding only after consideration,
    albeit deferential, of the Government’s explanation concerning the
    risk of an enumerated harm.
    Assessing the Government’s showing of a good reason to believe
    that an enumerated harm may result will present a district court with
    a   delicate   task.    While    the   court     will    normally    defer   to    the
    Government’s considered assessment of why disclosure in a particular
    case may result in an enumerated harm related to such grave matters as
    international terrorism or clandestine intelligence activities, it
    cannot,   consistent     with    strict       scrutiny    standards,      uphold     a
    nondisclosure requirement on a conclusory assurance that such a
    likelihood exists.     In this case, the director of the FBI certified
    that “the disclosure of the NSL itself or its contents may endanger
    the   national   security   of   the    United    States.”      To    accept      that
    conclusion without requiring some elaboration would “cast Article III
    judges in the role of petty functionaries, persons required to enter
    as a court judgment an executive officer’s decision, but stripped of
    capacity to evaluate independently whether the executive’s decision is
    -44-
    correct.” Gutierrez de Martinez v. Lamagno, 
    515 U.S. 417
    , 426 (1995).
    In showing why disclosure would risk an enumerated harm, the
    Government must at least indicate the nature of the apprehended harm
    and provide a court with some basis to assure itself (based on in
    camera    presentations     where    appropriate)     that     the   link    between
    disclosure and risk of harm is substantial.15                  As the Government
    acknowledges,    “Nothing    in     [subs]ection     3511(b)    would   require      a
    district court to confine judicial review to the FBI’s necessarily
    unelaborated public statement about the need for nondisclosure.                    The
    provisions in [subs]ections 3511(d) and (e) for ex parte and in camera
    review provide a ready mechanism for the FBI to provide a more
    complete explanation of its reasoning, and the court is free to elicit
    such an explanation as part of the review process.” Reply Br. for
    Appellants at 10 n.4.
    We have every confidence that district judges can discharge their
    review    responsibility      with     faithfulness      to     First       Amendment
    considerations   and   without      intruding   on    the    prerogative      of   the
    Executive Branch to exercise its judgment on matters of national
    security.    Such a judgment is not to be second-guessed, but a court
    must receive some indication that the judgment has been soundly
    15
    The Government sought to amplify its grounds for nondisclosure
    in a classified declaration submitted ex parte to the District Court
    and made available for our in camera review. This declaration will be
    available to the District Court on remand.

    reached.        As the Supreme Court has noted in matters of similar
    gravity, the Constitution “envisions a role for all three branches
    when individual liberties are at stake.” Hamdi v. Rumsfeld, 
    542 U.S. 507
    , 536 (2004).
    The District Court’s second reason for considering the judicial
    review procedure of subsection 3511(b) deficient was a perceived
    preclusion of a court’s authority, when presented with a “plausible,
    reasonable, and specific” enumerated harm, to balance “the potential
    harm against the particular First Amendment interest raised by a
    particular challenge.” Doe II, 
    500 F. Supp. 2d at 418
    .                  We see no
    deficiency in this regard.         The balance sought by the District Court
    is an important aspect of judicial review of prior restraints. See,
    e.g., New York Times Co. v. United States, 
    403 U.S. 713
     (1971).              That
    is   why   we    have   interpreted   the   statutory   standard   to   permit   a
    nondisclosure requirement only upon an adequate demonstration that a
    good reason exists reasonably to apprehend a risk of an enumerated
    harm, and have expressly read the enumerated harms as being linked to
    international terrorism or clandestine intelligence activities.              As a
    result of this interpretation, the balance sought by the District
    Court is now inherent in the statutory standard.            A demonstration of
    a reasonable likelihood of potential harm, related to international
    terrorism       or   clandestine   intelligence   activities,   will    virtually
    always outweigh the First Amendment interest in speaking about such a
    -46-
    limited and particularized occurrence as the receipt of an NSL and
    will suffice to maintain the secrecy of the fact of such receipt.
    The District Court’s third objection to the judicial review
    procedure is far more substantial. The Court deemed inconsistent with
    strict scrutiny standards the provision of subsections 3511(b)(2) and
    (b)(3)   specifying   that   a   certification   by   senior   governmental
    officials that disclosure may “endanger the national security of the
    United States or interfere with diplomatic relations . . . shall be
    treated as conclusive unless the court finds that the certification
    was made in bad faith.” 
    18 U.S.C. § 3511
    (b)(2). See Doe II, 
    500 F. Supp. 2d at 419
    .   We agree.
    There is not meaningful judicial review of the decision of the
    Executive Branch to prohibit speech if the position of the Executive
    Branch that speech would be harmful is “conclusive” on a reviewing
    court, absent only a demonstration of bad faith.       To accept deference
    to that extraordinary degree would be to reduce strict scrutiny to no
    scrutiny, save only in the rarest of situations where bad faith could
    be shown. Under either traditional strict scrutiny or a less exacting
    application of that standard, some demonstration from the Executive
    Branch of the need for secrecy is required in order to conform the
    nondisclosure requirement to First Amendment standards.        The fiat of
    a governmental official, though senior in rank and doubtless honorable
    in the execution of official duties, cannot displace the judicial
    -47-
    obligation    to   enforce   constitutional      requirements.       “Under   no
    circumstances should the Judiciary become the handmaiden of the
    Executive.” United States v. Smith, 
    899 F.2d 564
    , 569 (6th Cir. 1990).
    V. Remedy
    To recapitulate our conclusions, we (1) construe subsection
    2709(c) to permit a nondisclosure requirement only when senior FBI
    officials certify that disclosure may result in an enumerated harm
    that is related to “an authorized investigation to protect against
    international terrorism or clandestine intelligence activities,” (2)
    construe subsections 3511(b)(2) and (b)(3) to place on the Government
    the burden to show that a good reason exists to expect that disclosure
    of receipt of an NSL will risk an enumerated harm, (3) construe
    subsections   3511(b)(2)     and   (b)(3)   to   mean   that   the   Government
    satisfies its burden when it makes an adequate demonstration as to why
    disclosure in a particular case may result in an enumerated harm, (4)
    rule that subsections 2709(c) and 3511(b) are unconstitutional to the
    extent that they impose a nondisclosure requirement without placing on
    the Government the burden of initiating judicial review of that
    requirement, and (5) rule that subsections 3511(b)(2) and (b)(3) are
    unconstitutional to the extent that, upon such review, a governmental
    official’s certification that disclosure may endanger the national
    security of the United States or interfere with diplomatic relations
    is treated as conclusive.
    -48-
    Implementing          these    conclusions      requires   us      to   apply     the
    principles of judicial interpretation and limited revision of statutes
    and consider the related issue of severance discussed in Part I,
    supra.     We are satisfied that conclusions (1), (2), and (3) fall
    within    our    judicial        authority     to   interpret   statutes      to     avoid
    constitutional objections or conform to constitutional requirements.
    Conclusions (4) and (5) require further consideration.
    We deem it beyond the authority of a court to “interpret” or
    “revise” the NSL statutes to create the constitutionally required
    obligation      of   the    Government       to   initiate   judicial    review      of    a
    nondisclosure requirement.               However, the Government might be able to
    assume such an obligation without additional legislation.                           As we
    discussed in Part IV(b)(i), supra, the Government’s concern about the
    potentially substantial burden of initiating litigation can be readily
    alleviated      by   use    of     the    reciprocal   notice   procedure      we     have
    suggested.
    If the Government uses the suggested reciprocal notice procedure
    as a means of initiating judicial review, there appears to be no
    impediment to the Government’s including notice of a recipient’s
    opportunity to contest the nondisclosure requirement in an NSL.                           If
    such notice is given, time limits on the nondisclosure requirement
    pending judicial review, as reflected in Freedman, would have to be
    applied to make the review procedure constitutional. We would deem it
    -49-
    to be within our judicial authority to conform subsection 2709(c) to
    First      Amendment   requirements,   by     limiting   the     duration    of   the
    nondisclosure requirement, absent a ruling favorable to the Government
    upon judicial review, to the 10-day period in which the NSL recipient
    decides whether to contest the nondisclosure requirement, the 30-day
    period in which the Government considers whether to seek judicial
    review, and a further period of 60 days in which a court must
    adjudicate the merits, unless special circumstances warrant additional
    time. See Thirty-Seven Photographs, 
    402 U.S. at 373-74
     (imposing time
    limits to satisfy constitutional requirements).               If the NSL recipient
    declines timely to precipitate Government-initiated judicial review,
    the     nondisclosure    requirement    would       continue,     subject    to   the
    recipient’s     existing   opportunities      for    annual     challenges   to   the
    nondisclosure requirement provided by subsection 3511(b).16                  If such
    an annual challenge is made, the standards and burden of proof that we
    have specified for an initial challenge would apply, although the
    16
    The District Court ruled that those opportunities were
    constitutionally flawed because they unduly prolonged the duration of
    the nondisclosure requirement, see Doe II, 
    500 F. Supp. 2d at 421-22
    .
    We are satisfied, however, that, once the Government has initiated
    judicial review and prevailed on the merits, limiting an NSL recipient
    to annual opportunities thereafter to terminate the nondisclosure
    requirement does not violate First Amendment procedural requirements.
    The information subject to nondisclosure is extremely limited, and,
    once the need for secrecy--avoiding risk of harm related to
    international terrorism--has been shown, that need is not likely to
    dissipate soon.
    -50-
    Government would not be obliged to initiate judicial review.
    In those instances where an NSL recipient gives notice of an
    intent to challenge the disclosure requirement, the Government would
    have several options for completing the reciprocal notice procedure by
    commencing such review. First, it is arguable that the Government can
    adapt the authority now set forth in subsection 3511(c) for the
    purpose of initiating judicial review.          That provision authorizes the
    Attorney General to “invoke the aid of any [relevant] district court”
    in the event of “a failure to comply with a request for . . .
    information made to any person or entity under section 2709(b)” or
    other provisions authorizing NSLs. 
    18 U.S.C. § 3511
    (c).             Since an NSL
    includes both a request for information and a direction not to
    disclose that the FBI has sought or obtained information, an NSL
    recipient’s timely notice of intent to disclose, furnished in response
    to notice in an NSL of an opportunity to contest the nondisclosure
    requirement, can perhaps be considered the functional equivalent of
    the “failure to comply” contemplated by subsection 3511(c).              Second,
    the   Government   might   be   able   to     identify   some   other   statutory
    authority to invoke the equitable power of a district court to prevent
    a disclosure that the Government can demonstrate would risk harm to
    national security.    Third, and as a last resort, the Government could
    seek explicit congressional authorization to initiate judicial review
    of a nondisclosure requirement that a recipient wishes to challenge.
    -51-
    We leave it to the Government to consider how to discharge its
    obligation to initiate judicial review.
    In view of these possibilities, we need not invalidate the
    entirety of the nondisclosure requirement of subsection 2709(c) or the
    judicial review provisions of subsection 3511(b).        Although the
    conclusive presumption clause of subsections 3511(b)(2) and (b)(3)
    must be stricken, we invalidate subsection 2709(c) and the remainder
    of subsection 3511(b) only to the extent that they fail to provide for
    Government-initiated judicial review.   The Government can respond to
    this partial invalidation ruling by using the suggested reciprocal
    notice procedure.   With this procedure in place, subsections 2709(c)
    and 3511(b) would survive First Amendment challenge.
    These partial invalidations of subsections 2709(c) and 3511(b)
    oblige us to consider the issue of severance.    The District Court,
    understandably unaware of the narrowing interpretations we have made,
    invalidated the entirety of subsection 2709(c) and the entirety of
    subsection 3511(b). See Doe II, 
    500 F. Supp. 2d at 424
    .         Then,
    concluding that Congress would not have wanted the NSL authorization
    contained in subsections 2709(a) and (b) to stand in the absence of a
    nondisclosure requirement, it invalidated the entirety of section
    2709. 
    Id.
       As a result of these rulings, the court enjoined FBI
    officials from issuing NSL letters under section 2709, enforcing the
    nondisclosure requirement of subsection 2709(c), and enforcing the
    -52-
    provisions     for   judicial         review    of   the   nondisclosure   requirement
    contained in subsection 3511(b). With the NSL statutes now construed
    to   avoid    some   of    the    Plaintiffs’        constitutional    challenges    and
    partially     invalidated        to   render     the    statutes   constitutional,    we
    disagree that section 2709 and subsection 3511(b) must be stricken and
    their enforcement enjoined.
    We have no doubt that if Congress had understood that First
    Amendment considerations required the Government to initiate judicial
    review of a nondisclosure requirement and precluded a conclusive
    certification by the Attorney General, it would have wanted the
    remainder of the NSL statutes to remain in force.                      Congress would
    surely have wanted the Government to retain the authority to issue
    NSLs   even    if    all   aspects       of    the     nondisclosure   requirement    of
    subsection 2709(c) and the judicial review provisions of section
    3511(b) had been invalidated.                  As the Government points out, even
    without a nondisclosure requirement, it can protect the national
    interest by issuing NSLs only where it expects compliance with a
    request for secrecy to be honored. See Br. for Appellants at 60-61.
    A fortiori, authority to issue NSLs should be preserved in view of the
    limiting constructions and limited invalidations we have ordered.                     We
    therefore sever the conclusive presumption language of subsection
    3511(b) and leave intact the remainder of subsection 3511(b) and the
    entirety of section 2709 (with Government-initiated judicial review
    -53-
    required).       As a result of this ruling, we modify the District Court’s
    injunction by limiting it to enjoining FBI officials from enforcing
    the nondisclosure requirement of section 2709(c) in the absence of
    Government-initiated judicial review.17
    There remains for consideration the issue of the procedure to be
    followed       with   respect   to    judicial       review    of     the   nondisclosure
    requirement with respect to the NSL issued to John Doe, Inc.                    Although
    we have ruled that the Government is obliged to initiate judicial
    review of a nondisclosure requirement, it would be pointless to
    dismiss the pending litigation and direct the Government to start
    anew.        With judicial review already initiated in the District Court
    and the constitutionality of the disclosure requirement salvaged by
    the   statutory       interpretations        and    partial    invalidations     we   have
    ordered, the sounder course is to remand so that the Government may
    have an opportunity to sustain its burden of proof and satisfy the
    constitutional        standards      we    have     outlined    for    maintaining    the
    disclosure requirement. See 
    28 U.S.C. § 2106
    .
    Conclusion
    Accordingly, for all the foregoing reasons, subsections 2709(c)
    17
    With the Government having withdrawn its request for the
    information originally sought by the NSL issued to John Doe, Inc., and
    our severance ruling having retained the entirety of section 2709, we
    need not consider the constitutionality of using NSLs to request
    information.

    and   3511(b)   are   construed   in   conformity   with   this   opinion   and
    partially invalidated only to the extent set forth in this opinion,
    the injunction is modified as set forth in this opinion, and the
    judgment of the District Court is affirmed in part, reversed in part,
    and remanded for further proceedings consistent with this opinion.
