    INTRODUCTION
    Between 2018 and 2020, Electric Frontier Foundation, Inc. (EFF) moved to unseal
    affidavits filed in support of executed search warrants requested by the San Bernardino
    County Sheriff’s Department (the Sheriff) and issued under seal by the San Bernardino
    Superior Court between March 2017 and March 2018. The trial court denied EFF’s
    motion and ordered the affidavits to remain sealed. EFF appeals, and we affirm.
    II.
    FACTUAL AND PROCEDURAL BACKGROUND
    EFF is a “non-profit civil liberties organization working to protect and promote
    fundamental liberties in the digital world.” According to EFF, cell-site simulators always
    collect the digital data of innocent people. “A cell-site simulator works as its name
    suggests—it pretends to be a cell tower on the network of the target phone’s service
    provider. It takes advantage of the fact that a cell phone—when turned on—constantly
    seeks out nearby cell towers, even if the user is not making a call. Furnished with
    identifying information concerning the target phone, the cell-site simulator searches for
    2
    that phone. When the cell-site simulator is close enough, the target phone will connect to
    it as though it were a cell tower.” (A.L.R. Criminal Law, Art. XVII, § 392.38(15).
    EFF claims law enforcement authorities in San Bernardino County lead the state in
    the use of cell-site simulators. According to EFF, the Sheriff regularly seeks warrants to
    use cell-site simulators while moving to keep the warrants sealed indefinitely, and the
    San Bernardino County Superior Court (the Superior Court) largely grants the request
    when issuing the warrants. EFF has sought information about numerous search warrants
    issued by the Superior Court, but this case is about EFF’s request for eight search
    warrants.
    Because of its concerns about the use of cell-site simulators, EFF petitioned to
    unseal eight “search warrant packets” that contained warrants issued by the Superior
    Court between March 2017 and March 2018 that allowed the Sheriff to use cell-site
    1
    simulators. (See Cal. Rules, rule 2.551(h)(2). ) EFF sought the search warrant materials
    “to learn more about (1) the nature of the offenses under investigation, (2) the expertise
    and qualities of the affiants, (3) why the affiant believes the searches will assist the
    investigation, (4) the nature of the information to be provided under the warrant, (5) what
    providers must do to comply with the warrant, and (6) reasons for seeking sealing and/or
    nondisclosure.”
    1
    All further references to the “Rules” are to the California Rules of Court.
    3
    The Sheriff and the San Bernardino County District Attorney (collectively, the
    County) did not object to the unsealing of one warrant packet (SBSW 18-0850), but
    opposed the unsealing of portions of the seven other warrant packets.
    Specifically, the County argued the returns to the executed search warrants and the
    2
    so-called “Hobbs affidavits” in support of the warrants should remain sealed
    indefinitely, because they contain sensitive information about confidential informants
    (Evid. Code, § 1041) and “official information,” meaning information “acquired in
    confidence by a public employee in the course of his or her duty and not open, or
    officially disclosed, to the public prior to the time the claim of privilege is made.” (Evid.
    Code, § 1040, subd. (a).) In total, the County argued about 80 pages of information from
    about 120 pages of the search warrant packets should remain sealed. Under the parties’
    stipulation, the County provided EFF with portions of the search warrant packets that the
    County did not oppose unsealing. The County then moved for judgment on EFF’s
    petition and requested that the warrant packets remain sealed except for the select
    portions that the County had provided to EFF.
    The trial court held a hearing on the County’s motion in January 2021. At the
    time of the hearing, the proceedings related to the eight search warrants were at different
    stages. All of the warrants had been executed and their related investigations had all been
    completed. Some of the warrants had contributed to three indictments and two
    convictions, while another defendant was still awaiting trial at the time of the hearing.

    People v. Hobbs (1994) 
    7 Cal.4th 948
    , 962 (Hobbs).
    4
    After a hearing on the parties’ requests, the trial court denied EFF’s petition and
    3
    ordered the affidavits to remain sealed indefinitely. The trial court found that EFF was
    not entitled to the release of the affidavits and, even if it were, the County had a
    compelling interest in keeping them sealed to protect “confidential informant identity”
    and investigatory “sources and methods.” The court further found that nothing in the
    Hobbs affidavits could be even partially released. EFF timely appealed.
    III.
    DISCUSSION
    EFF argues the trial court should have unsealed the search warrant affidavits under
    Penal Code section 1534, subdivision (a) (section 1534(a)), Rules 2.550 and 2.551, the
    First Amendment, the California Constitution, and common law. We disagree.
    1. EFF’s Standing
    The County suggests that EFF lost standing to move to unseal the affidavits once
    the trial court decided that they should remain sealed. We disagree. “‘A litigant’s
    standing to sue is a threshold issue to be resolved before the matter can be reached on the
    merits. [Citation.]’” (Troyk v. Farmers Group, Inc. (2009) 
    171 Cal.App.4th 1305
    , 1345,
    italics added.) A party’s standing is thus a jurisdictional issue “unrelated to the merits” of
    the action. (Hudis v. Crawford (2005) 
    125 Cal.App.4th 1586
    , 1592.) EFF, like every
    other member of the public, “‘has a legitimate interest and right of general access to court
    3
    The trial court also ordered that the returns to the search warrants remain sealed,
    but EFF does not challenge that order. EFF appeals only the trial court’s order sealing
    the Hobbs affidavits.
    5
    records’” and thus has standing to sue to unseal the search warrants. (Sander v. State Bar
    of California (2013) 
    58 Cal.4th 300
    , 318; Rule 2.551(h)(2) [“A party or member of the
    public may move, apply, or petition . . . to unseal a record.”].)
    2. Section 1534(a)
    Section 1534(a) provides that a warrant and its related documents need not be
    made public for 10 days after its issuance. “Thereafter, if the warrant has been executed,
    the documents and records shall be open to the public as a judicial record.” (§ 1534(a).)
    EFF argues that the search warrant packets had to be unsealed under section
    1534(a) because the warrants had been executed long before EFF moved to unseal them.
    But, as the County correctly observes, the confidential informant privilege in Evidence
    Code section 1041 creates “an exception to [section 1534(a)].” (Hobbs, 
    supra,
     7 Cal.4th
    at p. 962.) Under this exception, a search warrant affidavit that contains information
    about a confidential informant, also known as a “Hobbs affidavit,” may be sealed in
    whole or in part to protect the informant’s identity. (Id. at pp. 971-975; People v.
    Acevedo (2012) 
    209 Cal.App.4th 1040
    , 1052.) Similarly, under Evidence Code section
    1040, a public entity has a qualified right not to disclose official information if
    “[d]isclosure of the information is against the public interest because there is a necessity
    for preserving the confidentiality of the information that outweighs the necessity for
    disclosure in the interest of justice.” (Evid. Code, § 1040, subd. (b)(2).) This privilege
    applies to official non-public information obtained by prosecutors and their law
    enforcement counterparts. (See Wood v. Superior Court (2020) 
    46 Cal.App.5th 562
    , 584;
    6
    Shepherd v. Superior Court (1976) 
    17 Cal.3d 107
    , 123, overruled on other grounds by
    People v. Holloway (2004) 
    33 Cal.4th 96
    , 131.)
    EFF argues we should apply the four-part test in NBC Subsidiary (KNBC-TV, Inc.)
    v. Superior Court (1999) 
    20 Cal.4th 1178
     (NBC Subsidiary) to determine whether the
    trial court properly found the Hobbs affidavits should not be unsealed under section
    1534(a). But EFF does not cite, and we are unaware of, any case in which that test was
    4
    used to evaluate whether a Hobbs affidavit should be unsealed.
    On the other hand, Hobbs outlines a procedure trial courts must follow to
    determine whether to unseal a Hobbs affidavit. (Hobbs, supra, 7 Cal.4th at pp. 972-975.)
    “The court’s first step is to determine whether the affidavit or any major portion of it has
    been properly sealed. [Citation.] This question entails two determinations: ‘It must first
    be determined whether sufficient grounds exist for maintaining the confidentiality of the
    informant’s identity. It should then be determined whether the entirety of the affidavit or
    any major portion thereof is properly sealed, i.e., whether the extent of the sealing is
    necessary to avoid revealing the informant’s identity.’ [Citation.] If the court ‘finds that
    4
    For instance, EFF relies heavily on In re Marriage of Nicholas (2010) 
    186 Cal.App.4th 1566
    , for the proposition Hobbs affidavits may be sealed only if NBC
    Subsidiary’s four-part test is satisfied. But that civil proceeding did not concern sealed
    search warrant materials. Noting that there is a “strong presumption . . . of public access
    to court records in ordinary civil trials,” the court there held that “family law departments
    may close their courtrooms and seal their court records only in limited circumstances, and
    only when they expressly identify the particular facts that support the existence of NBC
    Subsidiary’s constitutional standards.” (Id. at p. 1575.) As explained in more detail
    below, orders sealing search warrant materials apply different standards given the
    substantive and procedural differences between civil court records and search warrant
    materials.
    7
    any portion of the affidavit sealed by the magistrate can be further redacted, and the
    remaining excerpted portion made public without thereby divulging the informant’s
    identity, such additional limited disclosure should be ordered.’ [Citation.]” (People v.
    Heslington (2011) 
    195 Cal.App.4th 947
    , 957.) Trial courts must follow a similar
    procedure to determine whether official information should remain sealed under
    Evidence Code section 1040. (See People v. Acevedo, supra, 209 Cal.App.4th at p. 1056;
    People v. Bradley (2017) 
    7 Cal.App.5th 607
    , 626; People v. Montgomery (1988) 
    205 Cal.App.3d 1011
    , 1021.) We are unaware of any authority that suggests the NBC
    Subsidiary test supplanted these procedures.
    EFF argues, and the County agrees, that we review de novo the trial court’s ruling
    that nothing in the Hobbs affidavits should be unsealed. We disagree. Our Supreme
    Court has held that a trial court’s ruling that official information under Evidence Code
    section 1040 should not be disclosed is reviewed for an abuse of discretion. (See People
    v. Suff (2014) 
    58 Cal.4th 1013
    , 1059 [“A trial court has discretion to deny disclosure [of
    official information] . . . when the necessity for confidentiality outweighs the necessity
    for disclosure . . . [and its] ruling is reviewed under the abuse of discretion standard.”].)
    The court in Hobbs also held that the trial court did not abuse its discretion “in
    conducting its own in camera review of the sealed materials [and] affirming the
    magistrate’s determination that the sealing of the entirety of [the search warrant
    application] was necessary to implement the People’s assertion of the informant’s
    privilege” under Evidence Code section 1041. (Hobbs, supra, 7 Cal.4th at p. 976.)
    8
    These holdings are consistent with the court’s many cases holding that a trial court’s
    ruling that evidence is statutorily privileged and need not be disclosed is reviewed for an
    abuse of discretion. (E.g., Menendez v. Superior Court (1992) 
    3 Cal.4th 435
    , 457, fn. 18;
    People v. Avila (2006) 
    38 Cal.4th 491
    , 607.)
    At oral argument, EFF vigorously argued that we should apply a de novo standard
    of review. But the cases EFF cited in its briefs and at oral argument are either
    distinguishable or unpersuasive.
    The main case EFF (and the County) relies on is People v. Jackson (2005) 
    128 Cal.App.4th 1009
    , 1020 (Jackson). There, various news organizations appealed the trial
    court’s denial of their motion to unseal various documents, including search warrant
    affidavits, under the predecessor to California Rule of Court, rule 2.550 in the child
    molestation case against pop star Michael Jackson. (Id. at p. 1014.) The Jackson court
    broadly read our Supreme Court’s decision in In re George T. (2004) 
    33 Cal.4th 620
    , 634
    (George T.) and the United States Supreme Court’s decision in Bose Corp. v. Consumers
    Union of U.S., Inc. (1984) 
    466 U.S. 485
     (Bose), as holding that “cases implicating First
    5
    Amendment rights are subject to independent review.” (Jackson, supra, at p. 1021.)
    5
    “Independent review” is not the same as de novo review. (George T., supra, 33
    Cal.4th at p. 634.) Under independent review, the appellate court defers to the trial
    court’s credibility determinations, whereas under de novo review the appellate court
    “‘makes an original appraisal of all the evidence to decide whether or not it believes’ the
    outcome should have been different.” (Ibid.) The distinction is immaterial here because
    the trial court did not take testimony and made no credibility determinations, so EFF
    argues (and we agree) that independent review is equivalent to de novo review here. (See
    Jackson, supra, 128 Cal.App.4th at p. 1021.)
    9
    But George T., Bose, and the First Amendment cases it discussed were about whether
    certain speech was protected under the First Amendment. In that context, courts
    routinely apply independent review to resolve whether the speech at issue is
    constitutionally protected. (See George T., supra, at pp. 632-634.) In George T., for
    instance, the court had to decide whether the minor’s speech was a criminal threat or
    lawful speech. (Ibid.) In Bose, the high court had to decide whether a magazine article
    was defamatory or protected speech. (Bose, 
    supra,
     466 U.S. at p. 505; Krinsky v. Doe 6
    (2008) 
    159 Cal.App.4th 1154
    , 1162 [applying independent review under Bose because
    “the appellate issue is whether a particular communication falls outside the protection of
    the First Amendment”].)
    But neither decision concerned whether court records should be sealed or unsealed
    due to First Amendment concerns. Neither George T., Bose nor the Jackson courts had
    occasion to consider Evidence Code sections 1040 or 1041 and the corresponding
    standard of review for a trial court’s decision under either provision.
    The Jackson court did, however, note that “‘codified privileges and decisional
    rules together comprise an exception to [section 1534(a)’s] requirement that the contents
    of a search warrant . . . become a public record once the warrant is executed.’” (Jackson,
    supra, 128 Cal.App.4th at pp. 1022-1023, quoting Hobbs, 
    supra, at p. 962
    .) Hobbs
    confirms that trial courts must exercise their “‘broad discretion’” to balance these
    privileges and rules against other interests, such as a defendant’s Fourth Amendment
    rights or his right to a fair trial when deciding whether to keep search warrant materials
    10
    sealed. (Hobbs, 7 Cal.4th at p. 970.) In Hobbs, for instance, the trial court denied a
    criminal defendant’s motion to unseal search warrant materials on the ground that doing
    so would jeopardize the safety of a confidential informant even though the defendant
    sought the materials to challenge the legality of a search warrant. (Id. at pp. 955-957.)
    Our Supreme Court held the trial court properly “acted within its sound discretion” in
    denying the motion. (Id. at p. 976.)
    We discern no compelling reason why a trial court’s ruling on a criminal
    defendant’s motion to unseal search warrant materials that may show that the resulting
    search violated the defendant’s Fourth Amendment rights should be reviewed for an
    abuse of discretion while a motion to unseal search warrants should be reviewed de novo
    when the First Amendment is implicated. Several courts have held explicitly that a trial
    court’s sealing order is reviewed for an abuse of discretion even when the First
    Amendment is at play. (See, e.g., United States v. Doe (2d Cir. 1995) 
    63 F.3d 121
    , 125
    [reviewing order closing court proceedings for an abuse of discretion]; Flynt v. Lombardi
    (8th Cir. 2018) 
    885 F.3d 508
    , 511 [“[W]e review the district court’s ultimate decision to
    seal or unseal for an abuse of discretion”]; United States v. Doe (9th Cir. 2017) 
    870 F.3d 991
    , 996 [“[W]e review a decision whether or not to seal the judicial records for abuse of
    discretion”]; In re Los Angeles Times Communications LLC (D.C. Cir. 2022) 
    28 F.4th 292
    , 297 [same].) We therefore respectfully disagree with the Jackson court’s overly
    broad reading of George T. and Bose as holding that that all cases implicating the First
    Amendment require independent or de novo review.
    11
    The two other cases EFF primarily relied on in its briefs are similarly
    distinguishable. Neither Overstock.com, Inc. v. Goldman Sachs Group, Inc. (2014) 
    231 Cal.App.4th 471
     nor Mercury Interactive Corp. v. Klein, 
    158 Cal.App.4th 60
    , 81 (2007),
    involved search warrants, Hobbs affidavits, or confidential information subject to
    nondisclosure under Evidence Code sections 1040 or 1041. These cases therefore do not
    apply here. (People v. Ault (2004) 
    33 Cal.4th 1250
    , 1268, fn. 10 [“[C]ases are not
    authority for propositions not considered.”].)
    EFF emphasized at oral argument that various appellate courts have applied de
    novo review in “right to access” cases implicating the First Amendment. But we must
    decide whether the trial court erroneously denied EFF’s motion to unseal under Evidence
    Code sections 1040 and 1041 or whether EFF’s First Amendment rights trump those
    statutory privileges. Again, our Supreme Court has made clear that we review that
    decision for an abuse of discretion. (See Hobbs, 
    supra,
     7 Cal.4th at p. 971; People v.
    Suff, supra, 58 Cal.4th at p. 1059; see also People v. Luttenberger (1990) 
    50 Cal.3d 1
    , 21
    [trial court has discretion to order discovery concerning confidential informant’s
    statements in warrant affidavit].) Our colleagues in other courts of appeal have followed
    suit. (See e.g., People v. Washington (2021) 
    61 Cal.App.5th 776
    , 794 [“We review the
    trial court ruling on a motion to unseal a search warrant affidavit for an abuse of
    discretion,” citing Hobbs, 
    supra,
     7 Cal.4th at p. 976.]; People v. Bradley (2017) 
    7 Cal.App.5th 607
    , 620 [reviewing trial court’s decision to deny disclosure of an
    12
    informant’s identity under Evidence Code section 1041 for abuse of discretion]; People v.
    Acevedo, supra, 209 Cal.App.4th at p. 1055.)
    This makes sense because when deciding whether to seal or unseal a Hobbs
    affidavit when the People invoke the protections of Evidence Code sections 1040 or
    1041, the trial court must make a fundamentally discretionary decision. The court must
    weigh the government’s interests in maintaining information confidential against the
    public’s general right to access court records (or a criminal defendant’s right to challenge
    a warrant). (See Hobbs, 
    supra,
     7 Cal.4th at pp. 962, 971-972; People v. Galland (2008)
    
    45 Cal.4th 354
    , 367.) After all, “the First Amendment right of access is flexible, not
    absolute” and must sometimes yield to “an overriding interest,” such as protecting
    information deemed privileged under Evidence Code sections 1040 and 1041. (See
    People v. Connor (2004) 
    115 Cal.App.4th 669
    , 697; Hobbs, 
    supra, at pp. 962, 971-971
    ;
    see also Craemer v. Superior Court (1968) 
    265 Cal.App.2d 216
    , 222 [“[W]here there is
    no contrary statute or countervailing public policy, the right to inspect public records
    must be freely allowed.”].)
    We therefore conclude the abuse-of-discretion standard is appropriate here. (See
    Davis v. Superior Court (2010) 
    186 Cal.App.4th 1272
    , 1277 [“We review the trial court’s
    ruling concerning the disclosure of the identity of a confidential informant under the
    abuse of discretion standard,” citing Hobbs, 
    supra,
     7 Cal.4th at p. 976; see also People v.
    Bradley, supra, 7 Cal.App.5th at p. 620; People v. Kelly (2018) 
    28 Cal.App.5th 886
    ,
    906.)
    13
    “To establish an abuse of discretion, [a party] must demonstrate that the trial
    court’s decision was so erroneous that it ‘falls outside the bounds of reason.’ [Citations.]
    A merely debatable ruling cannot be deemed an abuse of discretion. [Citations.] An
    abuse of discretion will be ‘established by “a showing the trial court exercised its
    discretion in an arbitrary, capricious, or patently absurd manner that resulted in a
    manifest miscarriage of justice. . . .”’” (People v. Bryant, Smith, and Wheeler (2014) 
    60 Cal.4th 335
    , 390.)
    We find no abuse of discretion here. We have thoroughly reviewed the Hobbs
    affidavits and conclude that the trial court reasonably found that the information they
    contain is either official information under Evidence Code section 1040 or information
    that must remain sealed to avoid revealing a confidential informant’s identity. The trial
    court thus reasonably found that EFF’s reasons for wanting to unseal the Hobbs
    affidavits—to learn more about the Sheriff’s use of cell-site simulators—do not outweigh
    the County’s interest in protecting the official information and the identity of confidential
    informants contained in the affidavits. There was nothing arbitrary, capricious, or
    patently absurd about the trial court’s rulings. (See Jackson, supra, 128 Cal.App.4th at p.
    1020 [noting in dicta that if abuse of discretion standard applied to order denying motion
    to unseal search warrant materials, the case would be “easily resolved” because the trial
    courts “reflect careful and reasoned analysis and insight into the important constitutional
    principles involved”]; People v. Washington, supra, 61 Cal.App.5th at pp. 794-795.) We
    14
    therefore conclude the trial court did not abuse its discretion under section 1532(a) or
    Evidence Code sections 1040 and 1041 in declining to unseal the Hobbs affidavits.
    Although we find the abuse-of-discretion standard to be the appropriate standard
    of review here, we would still affirm the trial court’s ruling under Evidence Code
    sections 1040 and 1041 under a de novo or independent standard of review. Our review
    of the Hobbs affidavits and the record as a whole confirms that unsealing the affidavits
    “would tend to reveal the identity” of confidential informants. (People v. Martinez
    (2005) 
    132 Cal.App.4th 233
    , 242.) Thus, the Hobbs affidavits were “properly ordered
    sealed, and the court correctly denied” EFF’s motion to unseal them. (Ibid.)
    This conclusion is buttressed by our conclusion, explained in more detail below,
    that EFF does not have a First Amendment right to the affidavits. Given that conclusion,
    it follows that the trial court properly found that the County’s interests in maintaining the
    Hobbs affidavits sealed as privileged under Evidence Code sections 1040 and 1041
    outweighed EFF’s alleged First Amendment right to the affidavits. We therefore affirm
    the trial court’s order denying unsealing the Hobbs affidavits under section 1534(a) under
    either de novo or abuse-of-discretion review.
    3. Rules 2.550 and 2.551
    EFF also contends the trial court should have unsealed the Hobbs affidavits under
    Rules 2.550 and 2.551. We disagree.
    15
    Rules 2.550 and 2.551 “provide a standard and procedures for courts to use when a
    request is made to seal a record” or unseal a record, but they “do not apply to records that
    courts must keep confidential by law.” (Rule 2.550, Advisory Committee Comment;
    Overstock.com, supra, 231 Cal.App.4th at p. 488 (Overstock.com) [“[T]he court must
    consider the same criteria pertinent to a motion to seal when ruling on a request to unseal
    (rule 2.551(h)(4)].). Records that must be kept confidential by law include “search
    warrant affidavits sealed under” Hobbs. (Rule 2.550, Advisory Committee Comment.)
    The Rules thus did not require the trial court to unseal confidential informant information
    protected under Hobbs.
    The Rules also did not require the trial court to unseal official information
    privileged under Evidence Code section 1040. The Rules control only “‘to the extent that
    they are not inconsistent with legislative enactments.’” (Sara M. v. Superior Court
    (2005) 
    36 Cal.4th 998
    , 1011.) The Rules thus do not override the trial court’s proper
    finding that the official information in the Hobbs affidavits should remain sealed under
    Evidence Code section 1040.
    4. First Amendment
    EFF argues that it has a First Amendment right to have the Hobbs affidavits
    unsealed and that the privileges afforded by Evidence Code sections 1040 and 1041 must
    yield to that right. We disagree.
    16
    To determine whether a member of the public like EFF has a First Amendment
    right of access to a judicial proceeding or the documents from the proceeding, we first
    apply the United States Supreme Court’s history and utility test. (See NBC Subsidiary,
    supra, 20 Cal.4th at pp. 1217-1219; Sorenson v. Superior Court (2013) 
    219 Cal.App.4th 409
    , 432.) Under that test, we “examine whether 1) historical experience counsels in
    favor of recognizing a qualified First Amendment right of access to the proceeding [and
    related documents] and 2) whether public access would play a ‘significant positive role in
    the functioning of the particular process in question.’” (Times Mirror Co. v. United
    States (9th Cir. 1989) 
    873 F.2d 1210
    , 1213 (Times Mirror), quoting Press-Enterprise Co.
    v. Superior Court (1986) 
    478 U.S. 1
    , 8 (Press-Enterprise).) When applying this test, our
    review is de novo. (See In re in the matter of The Search of Fair Finance (6th Cir. 2012)
    
    692 F.3d 424
    , 434, fn. 4 (Fair Finance).)
    Relying on cases from jurisdictions outside of California, the County argues EFF
    fails the first prong of the Press-Enterprise test because there is no historical tradition of
    public access to search warrant materials. EFF contends Jackson, supra,
    128 Cal.App.4th 1009
     applied the history and utility test and found there is a First Amendment right to
    sealed search warrant materials.
    In Jackson, the trial court sealed search warrants and supporting materials to
    protect the privacy of minors allegedly abused by the defendant, pop star Michael
    Jackson. (Jackson, supra, 128 Cal.App.4th at p. 1015.) The appellant-newspaper argued
    the trial court made insufficient findings to support its order sealing the documents,
    17
    thereby violating the public’s First Amendment rights. (Id. at p. 1017.) Jackson and
    county counsel argued the trial court properly balanced the parties’ competing interests,
    but did not suggest that the newspaper had no First Amendment right to access the
    documents. (Ibid.)
    The Jackson court noted that “most judicial proceedings and records” are
    presumptively open to the public under the First Amendment while observing that NBC
    Subsidiary allows a court to keep certain records under seal. (Jackson, supra, 128
    Cal.App.4th at p. 1022.) Without analyzing whether the search warrant records were
    presumptively open to the public, the Jackson court affirmed, holding that the trial
    court’s sealing order met “the standards set forth in NBC Subsidiary.” (Ibid.) In other
    words, the Jackson court and parties simply assumed that the First Amendment applied to
    the sealed search warrants.
    EFF cites no other case to support its position that the First Amendment attaches
    to the Hobbs affidavits here. The County correctly notes that no California court has
    directly addressed the issue, while several cases from other jurisdictions hold that there is
    no First Amendment right to search warrant materials and note that courts are split on the
    issue. (See In re Granick (N.D.Cal. 2019) 
    388 F.Supp.3d 1107
    , 1123 [noting that
    “[c]ircuit courts are split on the question whether there is a First Amendment qualified
    right of access to warrant materials” and that the issue “has divided the district courts”].)
    18
    EFF argues that the out-of-state cases the County relies on are not controlling
    because they did not consider whether California law (namely, section 1534(a), enacted
    in 1963 and the 2015 California Electronic Communications Privacy Act (Pen. Code,
    §§ 1546.1 et seq.)), created a tradition of public access to search warrant materials filed in
    California courts. But in applying the history prong of the history and utility test to
    search warrant materials, we consider whether there is a longstanding national tradition
    of accessibility to the materials, not whether there is a California law-based tradition.
    (See Press-Enterprise, 
    supra,
     478 U.S. at p. 10 [“[T]he near uniform practice of state and
    federal courts has been to conduct preliminary hearings in open court”]; Richmond
    Newspapers, Inc. v. Virginia (1980) 
    448 U.S. 555
    , 563-569; Nixon v. Warner
    Communications, Inc. (1978) 
    435 U.S. 589
    , 597, fns. 7-8; United States v. Cohen
    (S.D.N.Y. 2019) 
    366 F.Supp.3d 612
    , 628; Seattle Times Co. v. Eberharter (1986) 
    105 Wn.2d 144
    , 154.) This is because state law does not dictate whether a longstanding
    national tradition of access exists for First Amendment purposes. (El Vocero de Puerto
    Rico v. Puerto Rico (1993) 
    508 U.S. 147
    , 151 [“[T]he ‘experience’ test . . . does not look
    to the particular practice of any one jurisdiction, but instead ‘to the experience in that type
    or kind of hearing throughout the United States”]; Alvarez v. Superior Court (2007) 
    154 Cal.App.4th 642
    , 655 [“California’s practice of releasing postindictment grand jury
    transcripts when there is no reasonable likelihood of prejudice does not transmogrify a
    purely statutory right of access into a constitutional entitlement.”]; see also Press-
    Enterprise Co. v. Superior Court (1984)
    37 Cal.3d 772
     [holding no First Amendment
    19
    right to public access to preliminary hearings in part because Penal Code section 868
    allowed those hearings to be closed to public], overruled on First Amendment grounds in
    Press-Enterprise, 
    supra,
     
    478 U.S. 1
    , in part because of long tradition in other
    jurisdictions of keeping preliminary hearings open to the public].)
    Moreover, there is no California-based tradition of disclosing materials that are
    exempt from disclosure under section 1534(a) because they are privileged under
    Evidence Code sections 1040 or 1041. For the reasons explained above, trial courts may
    properly keep such records under seal.
    EFF alternatively argues that some of the cases the County relies on are
    distinguishable because they involved pre-indictment requests for search warrant
    materials, not materials concerning warrants already executed in cases where indictments
    have already been filed. (E.g., Times Mirror, supra, 
    873 F.2d 1210
     [holding no First
    Amendment to search warrant materials “when an investigation is ongoing but before
    indictments have been returned”].)
    But the case the County mainly relies on, Fair Finance, supra, 
    692 F.3d 424
    , held
    there was no First Amendment right to search warrant materials irrespective of the stage
    of the proceedings. In that case, the district court denied two newspapers’ motion to
    unseal search warrant materials after the defendant had been indicted. (Id. at p. 428.)
    The Sixth Circuit affirmed, finding that there was “no evidence” that search warrant
    materials have “historically been [made] open to the press and public,” even after the
    warrants had been executed. (Id. at p. 430.) Because there is no “historical tradition of
    20
    accessibility to documents filed in search warrant proceedings,” the Sixth Circuit held
    that the newspapers had no First Amendment right to access the warrant materials. (Id. at
    p. 431.)
    While acknowledging Fair Finance, EFF asks us to follow In re Search Warrant
    for Secretarial Area Outside Office of Gunn (8th Cir. 1988) 
    855 F.2d 569
     (Gunn), which
    held there is a First Amendment right to search warrant materials, even pre-execution.
    Gunn reasoned that because search warrants and supporting affidavits are traditionally
    filed as public records, they are generally open to the public and thus accessible under the
    First Amendment. (Id. at p. 573.) But Gunn ignored the Supreme Court’s repeated
    observation that search warrant proceedings and materials traditionally are not publicly
    accessible. (E.g., United States v. United States District Court (1972) 
    407 U.S. 297
    , 321
    [“[A] warrant application involves no public or adversary proceedings: it is an ex parte
    request before a magistrate or judge”]; Franks v. Delaware (1978) 
    438 U.S. 154
    , 169
    [warrant proceedings are “necessarily ex parte, since the subject of the search cannot be
    tipped off to the application for a warrant lest he destroy or remove evidence”].)
    As the County correctly puts it, Gunn is an “outlier.” As far as we are awarel,
    Gunn conflicts with every federal circuit court and all but one state court of last resort
    that has considered whether there is a First Amendment right to search warrant materials.
    (See Fair Finance, supra, 692 F.3d at p. 433, fn. 3; Times Mirror, supra, 873 F.2d at p.
    1218; Baltimore Sun Co. v. Goetz (4th Cir. 1989) 
    886 F.2d 60
    , 64-65; Seattle Times Co.
    v. Eberharter, 
    supra,
     105 Wn.2d at p. 154; Newspapers of New England, Inc. v. Clerk-

    , 189;
    but see State v. Archuleta (Utah 1993) 
    857 P.2d 234
    , 239 [following Gunn].) We
    therefore join the overwhelming majority of state and federal courts and decline to follow
    Gunn.
    EFF alternatively argues that the bulk of these cases are distinguishable because
    they do not involve post-execution, post-arrest, and/or post-indictment search warrant
    materials. They argue that the stage of the proceedings is sometimes dispositive, noting
    that the Ninth Circuit has held that “[p]ost-investigation, however, warrant materials
    ‘have historically been available to the public.’” (United States v. Business of Custer
    Battlefield Museum & Store Located at Interstate 90, Exit 514, S. of Billings, Montana
    (9th Cir. 2011) 
    658 F.3d 1188
    , 1193 (Custer Battlefield).) But that statement was in the
    context of the court’s analysis under the common law. (Ibid.) The Ninth Circuit
    expressly declined to address the issue under the First Amendment. (Ibid.) Like the
    Sixth Circuit, “[w]e cannot accept the argument that the common law right of access
    supports a finding here of an analogous First Amendment right of access to search
    warrant documents.” (Fair Finance, supra, 692 F.3d at p. 431; see also In re Granick,
    
    supra,
     388 F.Supp.3d at p. 1126 [noting Custer Battlefield’s holding but finding no First
    Amendment right to post-execution warrant materials in part because there was no
    22
    “controlling [Ninth Circuit] authority on the issue”].) In any event, we agree with Fair
    Finance that there is no tradition of public access to search warrant materials for First
    Amendment purposes irrespective of the stage of the warrant proceedings and the stage
    of any resulting indictment.
    EFF correctly notes, however, that even without a historical tradition of
    accessibility to search warrant materials, we may still find there is a First Amendment
    right to those materials based solely on Press-Enterprise’s utility prong. (NBC
    Subsidiary, supra, 20 Cal.4th at p. 1214, 1214, fn. 32; accord, In re Copley Press, Inc.
    (9th Cir. 2008) 
    518 F.3d 1022
    , 1026.) As applied here, the utility prong asks whether
    public access to the Hobbs affidavits will “‘play[] a significant positive role in the
    functioning’” of the search warrant process. (NBC Subsidiary, supra, at p. 1206.)
    Fair Finance considered the effects that granting access to post-execution, post-
    indictment search warrant materials would have on the warrant process and found that
    “access would be detrimental to the search warrant application and criminal investigatory
    processes.” (Fair Finance, supra, 692 F3d at p. 433.) In reaching that conclusion, the
    Sixth Circuit made a series of observations: “[T]he execution of the search does not
    eliminate the possibility of harm from the disclosure of the information contained in the
    documents. First and most obviously, because the documents must detail the
    government’s evidence of criminal activity so as to establish probable cause for a search,
    they would likely identify information sources, such as wiretaps and undercover
    operations, the continued utility of which will be compromised by disclosure. The safety
    23
    of confidential witnesses may also be compromised. The publication of search warrant
    documents may also reveal the government’s preliminary theory of the crime being
    investigated and enable criminal suspects to figure out which other places are likely to be
    searched as the investigation continues. In addition, although the execution of the search
    will have already served to alert the owner or occupant of the place being searched that
    he may be a criminal suspect, publication of search warrant documents, by revealing the
    extent of the government’s knowledge, could alert others that they, too, are suspects and
    could cause them to destroy evidence or to flee. [¶] A further concern arising from
    public access to search warrant documents is the fact that the government would need to
    be more selective in the information it disclosed in order to preserve the integrity of its
    investigations. This limitation on the flow of information to the magistrate judges could
    impede their ability to accurately determine probable cause. We are concerned also that
    access to the documents might reveal the names of innocent people who never become
    involved in an ensuing criminal prosecution, causing them embarrassment or censure. [¶]
    These examples are an incomplete list of the potential harms of disclosure. There are a
    variety of ways in which the criminal investigatory process may be harmed by making
    documents filed in search warrant proceedings publicly available. The critical point is
    that the importance of the confidentiality necessary for criminal investigations is well
    recognized [citations]. Publication of search warrant documents would serve only to
    jeopardize that interest.” (Fair Finance, supra, 692 F.3d at p. 432.)
    24
    These observations apply equally here. We also agree with the Sixth Circuit that
    “the greatest risk of these harms would stem from [the] release of the affidavits submitted
    in support of search warrant applications.” (Fair Finance, supra, 692 F.3d at p. 433.)
    Although granting EFF access to the Hobbs affidavits likely would provide some public
    benefits, such as enabling greater public oversight of County law enforcement, “these
    benefits are outweighed by the very particular harms described above that would affect
    the criminal investigatory process.” (Id. at p. 433.)
    We therefore conclude EFF has not satisfied the utility prong of the Press-
    Enterprise test. Because EFF fails both prongs of that test, EFF does not have a First
    Amendment right to the Hobbs affidavits. As a result, we need not determine whether
    the trial court properly kept the records sealed under NBC Subsidiary.
    But, even if EFF had a qualified First Amendment right to the Hobbs affidavits,
    the trial court properly kept them sealed under NBC Subsidiary’s four-part test that EFF
    urges us to apply here. Under that test, the Hobbs affidavits may be sealed only if the
    trial court “expressly finds (i) there exists an overriding interest supporting . . . sealing;
    (ii) there is a substantial probability that the interest will be prejudiced absent . . . sealing;
    (iii) the proposed . . . sealing is narrowly tailored to serve the overriding interest; and (iv)
    there is no less restrictive means of achieving the overriding interest.” (NBC Subsidiary,
    supra, 20 Cal.4th at pp. 1217-1218, fns. omitted.)
    25
    As for the first prong, the trial court correctly found that protecting the identities
    of confidential informants and the confidentiality of law enforcement investigatory
    practices is an “‘overriding interest’” supporting sealing. (See NBC Subsidiary, supra, 20
    Cal.4th at p. 1222, fn. 46, citing Fenner & Koley, Access to Judicial Proceedings: To
    Richmond Newspapers and Beyond (1981) 
    16 Harv. C.R.-C.L. L. Rev. 426
    , 443 [“A third
    category of countervailing interests encompasses the preservation of confidential
    investigative information, both general information regarding investigative procedures
    and specific information regarding ongoing investigations,” fn. omitted.)
    We agree with the trial court that those interests would be prejudiced if the Hobbs
    affidavits were unsealed. “We enter into this analysis keeping in mind that assessing the
    likely effect of an event by its nature calls for speculation.” (In re Willon (1996) 
    47 Cal.App.4th 1080
    , 1100.) But it is probable that confidential informants could be
    identified, even if their names remained redacted as EFF requests, by piecing together
    other, unredacted information in the affidavits. The County’s “confidential investigatory
    information” necessarily would be revealed if the affidavits were unsealed given that they
    contain detailed information about the circumstances and investigations that led County
    law enforcement to seek search warrants.
    The trial court also properly found that all of the Hobbs affidavits had to remain
    sealed and that even select portions of them could not be unsealed. “[R]edacting
    individual facts from the search warrant affidavit[s] is impossible. Benign information is
    inextricably intertwined with prejudicial information.” (Jackson, supra, 
    128 Cal.App.4th 26
    at p. 1026.) Limited redaction therefore may not sufficiently guard the overriding
    interests that justify sealing the Hobbs affidavits. (See Goff v. Graves (8th Cir. 2004) 
    362 F.3d 543
    , 550.)
    Although not every single line of the Hobbs affidavits contains confidential
    information, the affidavits are full of information about confidential informants, facts
    learned from those informants, and information about the County’s investigations and
    investigatory techniques. Redacting all of the confidential information in the affidavits
    “would yield, at best, unintelligible paragraphs.” (Jackson, supra, 128 Cal.App.4th at p.
    1028.) Thus, a “line-by-line redaction” of the affidavits is “not practicable.” (Gunn,
    supra, 855 F.2d at p. 574.) “[E]ffective, efficient, and fair procedures must be employed.
    [Citation.] Access only to those portions of the [Hobbs affidavits] that do not contain the
    implicated information would be a Pyrrhic victory for access, with little benefit to the
    functioning of the system.” (United States v. Gonzales (10th Cir. 1998) 
    150 F.3d 1246
    ,
    1261.)
    In short, even if the NBC Subsidiary test applies here, the trial court’s order
    satisfied it. The trial court therefore properly sealed the Hobbs affidavits under NBC
    Subsidiary.
    27
    5. California Constitution
    EFF next argues that it has a right to the Hobbs affidavits under article I, section 2
    6
    and section 3, subdivision (b) of the California Constitution (sections 2 and 3(b)), our
    state’s corollary to the First Amendment. We disagree.
    Section 2 provides “broad access rights to judicial hearings and records.” (Copley
    Press, Inc. v. Superior Court (1992) 
    6 Cal.App.4th 106
    , 111.) Section 3(b)(1) provides:
    “The people have the right of access to information concerning the conduct of the
    people’s business, and, therefore, the meetings of public bodies and the writings of public
    officials and agencies shall be open to public scrutiny.” Section 3(b)(2) states that “[a]
    statute, court rule, or other authority, including those in effect on the effective date of this
    subdivision, shall be broadly construed if it furthers the people’s right of access, and
    narrowly construed if it limits the right of access.” Under these constitutional mandates,
    “we must interpret the sealed records rules broadly to further the public’s right of access”
    unless there is “a clear requirement otherwise.” (Overstock.com, supra, 231 Cal.App.4th
    at p. 495.)
    Section 3(b), however, has an exception that EFF overlooks. Section 3(b)(5)
    provides that section 3(b), enacted in 2005, “does not repeal or nullify . . . any
    constitutional or statutory exception to the right to public records . . . including . . . any
    statute protecting the confidentiality of law enforcement and prosecution records.”
    6
    Section 2, subdivision (a) provides in full: “Every person may freely speak,
    write and publish his or her sentiments on all subjects, being responsible for the abuse of
    this right. A law may not restrain or abridge liberty of speech or press.”
    28
    Section 3(b) therefore does not override the exemptions from disclosure granted to search
    warrant materials under section 1534(a), the Evidence Code, the Rules, or the First
    Amendment. As a result, section 3(b) does not alter our conclusion above that the trial
    court properly sealed the Hobbs affidavits for the reasons discussed above.
    Section 2 likewise does not affect that conclusion. Although “in both language
    and scope it is broader than the First Amendment,” (San Jose Mercury-News v.
    Municipal Court (1982) 
    30 Cal.3d 498
    , 508), it has not been interpreted “as providing an
    equally extensive right of public access to court proceedings, even in criminal cases.”
    (NBC Subsidiary, supra, 20 Cal.4th at p. 1197, fn. 13.) For instance, our Supreme Court
    held that the California Constitution does not guarantee public access to preliminary
    hearings in criminal court. (Press-Enterprise Co. v. Superior Court, supra, 
    37 Cal.3d 772
    , overruled on other grounds in Press-Enterprise, 
    supra,
     
    478 U.S. 1
    .) The United
    States Supreme Court reversed, holding that the First Amendment mandated access.
    (Press-Enterprise, 
    supra,
     
    478 U.S. 1
    .) The high court thus held that the First
    Amendment granted the public right to access preliminary hearing proceedings that were
    otherwise closed to the public under the California Constitution.
    Across the nation, preliminary hearings have been traditionally open to the public
    while search warrant proceedings usually have been (and remain) ex parte proceedings
    closed to the public. (See El Vocero de Puerto Rico v. Puerto Rico, supra, 508 U.S. at
    pp. 150-151 [“The established and widespread tradition of open preliminary hearings
    among the States . . . .”]; United States v. United States District Court, supra, 407 U.S. at
    29
    p. 321.) Given our conclusion that EFF has no First Amendment right to the Hobbs
    affidavits, which were filed and sealed in a closed, ex parte criminal proceeding, it
    follows that the California Constitution does not require granting EFF access to the
    affidavits either. (See ibid.)
    6. Common Law
    Lastly, EFF argues it has a right to the Hobbs affidavits under the common law.
    “‘Common law rights provide the press and the public with less access than First
    Amendment rights,’ and the decision to seal or grant access to warrant papers is
    ‘“committed to the sound discretion of the judicial officer who issued the warrant.”’”
    (Overstock.com, supra, 231 Cal.App.4th at p. 490; accord, Custer Battlefield, 
    supra,
     658
    F.3d at p. 1197, fn. 7 [“The First Amendment is generally understood to provide a
    stronger right of access than the common law.”].) Because we conclude the trial court
    properly denied EFF access to the Hobbs affidavits under the First Amendment, the court
    did not abuse its discretion by denying EFF access under common law.
