    MCLANE CO., INC. v. EQUAL EMPLOYMENT
    OPPORTUNITY COMMISSION
    CERTIORARI TO THE UNITED STATES COURT OF APPEALS FOR
    THE NINTH CIRCUIT
    No. 15–1248. Argued February 21, 2017—Decided April 3, 2017
    Damiana Ochoa worked for eight years in a physically demanding job
    for petitioner McLane Co., a supply-chain services company. McLane
    requires employees in those positions—both new employees and
    those returning from medical leave—to take a physical evaluation.
    When Ochoa returned from three months of maternity leave, she
    failed the evaluation three times and was fired. She then filed a sex
    discrimination charge under Title VII of the Civil Rights Act of 1964.
    The Equal Employment Opportunity (EEOC) began an investigation,
    but McLane declined its request for so-called “pedigree information”:
    names, Social Security numbers, addresses, and telephone numbers
    of employees asked to take the evaluation. After the EEOC expanded
    the investigation’s scope both geographically (to cover McLane’s na-
    tional operations) and substantively (to investigate possible age dis-
    crimination), it issued subpoenas, as authorized by 42 U. S. C.
    §2000e–9, requesting pedigree information relating to its new inves-
    tigation. When McLane refused to provide the information, the
    EEOC filed two actions in Federal District Court—one arising out of
    Ochoa’s charge and one arising out of the EEOC’s own age-
    discrimination charge—seeking enforcement of its subpoenas. The
    District Judge declined to enforce the subpoenas, finding that the
    pedigree information was not relevant to the charges, but the Ninth
    Circuit reversed. Reviewing the District Court’s decision to quash
    the subpoena de novo, the court concluded that the lower court erred
    in finding the pedigree information irrelevant.
    Held: A district court’s decision whether to enforce or quash an EEOC
    subpoena should be reviewed for abuse of discretion, not de novo.
    Pp. 6–12.

    Syllabus
    (a) Both factors that this Court examines when considering wheth-
    er such decision should be subject to searching or deferential appel-
    late review point toward abuse-of-discretion review. First, the
    longstanding practice of the courts of appeals is to review a district
    court’s decision to enforce or quash an administrative subpoena for
    abuse of discretion. Title VII confers on the EEOC the same authori-
    ty to issue subpoenas that the National Labor Relations Act (NLRA)
    confers on the National Labor Relations Board (NLRB). During the
    three decades between the NLRA’s enactment and the incorporation
    of its subpoena-enforcement provisions into Title VII, every Circuit to
    consider the question had held that a district court’s decision on en-
    forcement of an NLRB subpoena is subject to abuse-of-discretion re-
    view. Congress amended Title VII to authorize EEOC subpoenas
    against this uniform backdrop of deferential appellate review, and
    today, nearly every Court of Appeals reviews a district court’s deci-
    sion whether to enforce an EEOC subpoena for abuse of discretion.
    This “long history of appellate practice,” Pierce v. Underwood, 
    487 U. S. 552
    , 558, carries significant persuasive weight.
    Second, basic principles of institutional capacity counsel in favor of
    deferential review. In most cases, the district court’s enforcement de-
    cision will turn either on whether the evidence sought is relevant to
    the specific charge or whether the subpoena is unduly burdensome in
    light of the circumstances. Both of these tasks are well suited to a
    district judge’s expertise. The first requires the district court to eval-
    uate the relationship between the particular materials sought and
    the particular matter under investigation—an analysis “variable in
    relation to the nature, purposes and scope of the inquiry.” Oklahoma
    Press Publishing Co. v. Walling, 
    327 U. S. 186
    , 209. And whether a
    subpoena is overly burdensome turns on the nature of the materials
    sought and the difficulty the employer will face in producing them—
    “ ‘fact-intensive, close calls’ ” better suited to resolution by the district
    court than the court of appeals. Cooter & Gell v. Hartmarx Corp.,
    
    496 U. S. 384
    , 404.
    Other functional considerations also show the appropriateness of
    abuse-of-discretion review. For one, the district courts’ considerable
    experience in making similar decisions in other contexts, see Buford
    v. United States, 
    532 U. S. 59
    , 66, gives them the “institutional ad-
    vantag[e],” 
    id., at 64
    , that comes with greater experience. Deferen-
    tial review also “streamline[s] the litigation process by freeing appel-
    late courts from the duty of reweighing evidence and reconsidering
    facts already weighed and considered by the district court,” Cooter &
    Gell, 
    496 U. S., at 404
    , something particularly important in a pro-
    ceeding designed only to facilitate the EEOC’s investigation. Pp. 6–9.
    (b) Court-appointed amicus’ arguments in support of de novo re-
    Cite as: 581 U. S. ____ (2017)                     3
    Syllabus
    view are not persuasive. Amicus claims that the district court’s pri-
    mary task is to test a subpoena’s legal sufficiency and thus requires
    no exercise of discretion. But that characterization is not inconsistent
    with abuse-of-discretion review, which may be employed to insulate
    the trial judge’s decision from appellate review for the same kind of
    functional concerns that underpin the Court’s conclusion that abuse
    of discretion is the appropriate standard.
    It is also unlikely that affording deferential review to a district
    court’s subpoena decision would clash with Court of Appeals deci-
    sions that instructed district courts to defer to the EEOC’s determi-
    nation about the relevance of evidence to the charge at issue. Such
    decisions are better read as resting on the established rule that the
    term “relevant” be understood “generously” to permit the EEOC “ac-
    cess to virtually any material that might cast light on the allegations
    against the employer.” EEOC v. Shell Oil Co., 
    466 U. S. 54
    , 68–69.
    Nor do the constitutional underpinnings of the Shell Oil standard re-
    quire a different result. While this Court has described a subpoena
    as a “ ‘constructive’ search,” Oklahoma Press, 
    327 U. S., at 202
    , and
    implied that the Fourth Amendment is the source of the requirement
    that a subpoena not be “too indefinite,” United States v. Morton Salt
    Co., 
    338 U. S. 632
    , 652, not every decision touching on the Fourth
    Amendment is subject to searching review. See, e.g., United States v.
    Nixon, 
    418 U. S. 683
    , 702. Cf. Illinois v. Gates, 
    462 U. S. 213
    , 236;
    Ornelas v. United States, 
    517 U. S. 690
    , distinguished. Pp. 9–11.
    (c) The case is remanded so that the Court of Appeals can review
    the District Court’s decision under the appropriate standard in the
    first instance. In doing so, the Court of Appeals may consider, as and
    to the extent it deems appropriate, any of McLane’s arguments re-
    garding the burdens imposed by the subpoena. Pp. 11–12.

    MCLANE COMPANY, INC., PETITIONER v. EQUAL
    EMPLOYMENT OPPORTUNITY COMMISSION
    ON WRIT OF CERTIORARI TO THE UNITED STATES COURT OF
    APPEALS FOR THE NINTH CIRCUIT
    [April 3, 2017]
    JUSTICE SOTOMAYOR delivered the opinion of the Court.
    Title VII of the Civil Rights Act of 1964 permits the
    Equal Employment Opportunity Commission (EEOC) to
    issue a subpoena to obtain evidence from an employer that
    is relevant to a pending investigation. The statute autho-
    rizes a district court to issue an order enforcing such a
    subpoena. The question presented here is whether a court
    of appeals should review a district court’s decision to
    enforce or quash an EEOC subpoena de novo or for abuse
    of discretion. This decision should be reviewed for abuse
    of discretion.
    I
    A
    Title VII of the Civil Rights Act of 1964 prohibits em-
    ployment discrimination on the basis of “race, color, reli-
    gion, sex, or national origin.” §703(a), 
    78 Stat. 255
    , 42
    U. S. C. §2000e–2(a). The statute entrusts the enforce-
    ment of that prohibition to the EEOC. See §2000e–5(a);
    EEOC v. Shell Oil Co., 
    466 U. S. 54
    , 61–62 (1984). The
    EEOC’s responsibilities “are triggered by the filing of a
    specific sworn charge of discrimination,” University of Pa.
    2                       MCLANE CO. v. EEOC
    Opinion of the Court
    v. EEOC, 
    493 U. S. 182
    , 190 (1990), which can be filed
    either by the person alleging discrimination or by the
    EEOC itself, see §2000e–5(b). When it receives a charge,
    the EEOC must first notify the employer, ibid., and must
    then investigate “to determine whether there is reasonable
    cause to believe that the charge is true,” University of Pa.,
    
    493 U. S., at 190
     (internal quotation marks omitted).
    This case is about one of the tools the EEOC has at its
    disposal in conducting its investigation: a subpoena. In
    order “[t]o enable the [EEOC] to make informed decisions
    at each stage of the enforcement process,” Title VII “con-
    fers a broad right of access to relevant evidence.” 
    Id., at 191
    . It provides that the EEOC “shall . . . have access to,
    for the purposes of examination, . . . any evidence of any
    person being investigated or proceeded against that re-
    lates to unlawful employment practices covered by” Title
    VII and “is relevant to the charge under investigation.” 42
    U. S. C. §2000e–8(a). And the statute enables the EEOC
    to obtain that evidence by “authoriz[ing] [it] to issue a
    subpoena and to seek an order enforcing [the subpoena].”
    University of Pa., 
    493 U. S., at 191
    ; see §2000e–9.1 Under
    that authority, the EEOC may issue “subp[o]enas requir-
    ing the attendance and testimony of witnesses or the
    production of any evidence.” 
    29 U. S. C. §161
    (1). An
    employer may petition the EEOC to revoke the subpoena,
    see ibid., but if the EEOC rejects the petition and the
    employer still “refuse[s] to obey [the] subp[o]ena,” the
    EEOC may ask a district court to issue an order enforcing
    it, see §161(2).
    A district court’s role in an EEOC subpoena enforcement
    proceeding, we have twice explained, is a straightforward
    ——————
    1 The
    statute does so by conferring on the EEOC the same authority
    given to the National Labor Relations Board to conduct investigations.
    See 42 U. S. C. §2000e–9 (“For the purpose of all . . . investigations
    conducted by the Commission . . . section 161 of title 29 shall apply”).

    Opinion of the Court
    one. See University of Pa., 
    493 U. S., at 191
    ; Shell Oil, 
    466 U. S., at 72, n. 26
    . A district court is not to use an en-
    forcement proceeding as an opportunity to test the
    strength of the underlying complaint. 
    Ibid.
     Rather, a
    district court should “ ‘satisfy itself that the charge is valid
    and that the material requested is “relevant” to the
    charge.’ ” University of Pa., 
    493 U. S., at 191
    . It should do
    so cognizant of the “generou[s]” construction that courts
    have given the term “relevant.” Shell Oil, 
    466 U. S., at
    68–69 (“virtually any material that might cast light on the
    allegations against the employer”). If the charge is proper
    and the material requested is relevant, the district court
    should enforce the subpoena unless the employer estab-
    lishes that the subpoena is “too indefinite,” has been is-
    sued for an “illegitimate purpose,” or is unduly burden-
    some. 
    Id., at 72, n. 26
    . See United States v. Morton Salt
    Co., 
    338 U. S. 632
    , 652–653 (1950) (“The gist of the protec-
    tion is in the requirement . . . that the disclosure sought
    shall not be unreasonable” (internal quotation marks
    omitted)).
    B
    This case arises out of a Title VII suit filed by a woman
    named Damiana Ochoa. Ochoa worked for eight years as
    a “cigarette selector” for petitioner McLane Co., a supply-
    chain services company. According to McLane, the job is a
    demanding one: Cigarette selectors work in distribution
    centers, where they are required to lift, pack, and move
    large bins containing products. McLane requires employ-
    ees taking physically demanding jobs—both new employ-
    ees and employees returning from medical leave—to take
    a physical evaluation. According to McLane, the evalua-
    tion “tests . . . range of motion, resistance, and speed”
    and “is designed, administered, and validated by a third
    party.” Brief for Petitioner 6. In 2007, Ochoa took three
    months of maternity leave. When she attempted to return
    4                   MCLANE CO. v. EEOC
    Opinion of the Court
    to work, McLane asked her to take the evaluation. Ochoa
    attempted to pass the evaluation three times, but failed.
    McLane fired her.
    Ochoa filed a charge of discrimination, alleging (among
    other things) that she had been fired on the basis of her
    gender. The EEOC began an investigation, and—at its
    request—McLane provided it with basic information about
    the evaluation, as well as a list of anonymous employees
    that McLane had asked to take the evaluation. McLane’s
    list included each employee’s gender, role at the company,
    and evaluation score, as well as the reason each employee
    had been asked to take the evaluation. But the company
    refused to provide what the parties call “pedigree infor-
    mation”: the names, Social Security numbers, last known
    addresses, and telephone numbers of the employees who
    had been asked to take the evaluation. Upon learning
    that McLane used the evaluation nationwide, the EEOC
    expanded the scope of its investigation, both geographi-
    cally (to focus on McLane’s nationwide operations) and sub-
    stantively (to investigate whether McLane had discrimi-
    nated against its employees on the basis of age). It issued
    subpoenas requesting pedigree information as it related to
    its new investigation. But McLane refused to provide
    the pedigree information, and so the EEOC filed two
    actions in Federal District Court—one arising out of
    Ochoa’s charge and one arising out of a separate age-
    discrimination charge the EEOC itself had filed—seeking
    enforcement of its subpoenas.
    The enforcement actions were assigned to the same
    District Judge, who, after a hearing, declined to enforce
    the subpoenas to the extent that they sought the pedigree
    information. See EEOC v. McLane Co., 
    2012 WL 1132758
    ,
    *5 (D Ariz., Apr. 4, 2012) (age discrimination charge); Civ.
    No. 12–2469 (D Ariz., Nov. 19, 2012), App. to Pet. for Cert.
    Cite as: 581 U. S. ____ (2017)                    5
    Opinion of the Court
    28–30 (Title VII charge).2 In the District Court’s view, the
    pedigree information was not “relevant” to the charges
    because “ ‘an individual’s name, or even an interview he or
    she could provide if contacted, simply could not shed light
    on whether the [evaluation] represents a tool of . . . dis-
    crimination.’ ” App. to Pet. for Cert. 29 (quoting 
    2012 WL 1132758
    , at *5; some internal quotation marks omitted).
    The Ninth Circuit reversed. See 
    804 F. 3d 1051
     (2015).
    Consistent with Circuit precedent, the panel reviewed the
    District Court’s decision to quash the subpoena de novo,
    and concluded that the District Court had erred in finding
    the pedigree information irrelevant. 
    Id., at 1057
    . But the
    panel questioned in a footnote why de novo review applied,
    observing that its sister Circuits “appear[ed] to review
    issues related to enforcement of administrative subpoenas
    for abuse of discretion.” 
    Id., at 1056, n. 3
    ; see infra, at 7
    (reviewing Court of Appeals authority).
    This Court granted certiorari to resolve the disagree-
    ment between the Courts of Appeals over the appropriate
    standard of review for the decision whether to enforce an
    EEOC subpoena. 579 U. S. ___ (2016). Because the United
    States agrees with McLane that such a decision should
    be reviewed for abuse of discretion, Stephen B. Kinnaird
    was appointed as amicus curiae to defend the judgment
    below. 580 U. S. ___ (2016). He has ably discharged his
    duties.
    ——————
    2 The District Court also refused to enforce the subpoena to the extent
    that it sought a second category of evidence: information about when
    and why those employees who had been fired after taking the test had
    been fired. The District Court provided no explanation for not enforc-
    ing the subpoena to the extent it sought this information, and the Court
    of Appeals reversed on that ground. 
    804 F. 3d 1051
    , 1059 (CA9 2015).
    McLane does not challenge this aspect of the Court of Appeals’ decision.

    6                   MCLANE CO. v. EEOC
    Opinion of the Court
    II
    A
    When considering whether a district court’s decision
    should be subject to searching or deferential appellate
    review—at least absent “explicit statutory command”—we
    traditionally look to two factors. Pierce v. Underwood, 
    487 U. S. 552
    , 558 (1988). First, we ask whether the “history
    of appellate practice” yields an answer. 
    Ibid.
     Second, at
    least where “neither a clear statutory prescription nor a
    historical tradition exists,” we ask whether, “ ‘as a matter
    of the sound administration of justice, one judicial actor is
    better positioned than another to decide the issue in ques-
    tion.’ ” 
    Id., at 558
    , 559–560 (quoting Miller v. Fenton, 
    474 U. S. 104
    , 114 (1985)). Both factors point toward abuse-of-
    discretion review here.
    First, the longstanding practice of the courts of appeals
    in reviewing a district court’s decision to enforce or quash
    an administrative subpoena is to review that decision for
    abuse of discretion. That practice predates even Title VII
    itself. As noted, Title VII confers on the EEOC the same
    authority to issue subpoenas that the National Labor
    Relations Act (NLRA) confers on the National Labor Rela-
    tions Board (NLRB). See n. 1, supra. During the three
    decades between the enactment of the NLRA and the
    incorporation of the NLRA’s subpoena-enforcement provi-
    sions into Title VII, every Circuit to consider the question
    had held that a district court’s decision whether to enforce
    an NLRB subpoena should be reviewed for abuse of discre-
    tion. See NLRB v. Consolidated Vacuum Corp., 
    395 F. 2d 416
    , 419–420 (CA2 1968); NLRB v. Friedman, 
    352 F. 2d 545
    , 547 (CA3 1965); NLRB v. Northern Trust Co., 
    148 F. 2d 24
    , 29 (CA7 1945); Goodyear Tire & Rubber Co. v.
    NLRB, 
    122 F. 2d 450
    , 453–454 (CA6 1941). By the time
    Congress amended Title VII to authorize EEOC subpoenas
    in 1972, it did so against this uniform backdrop of deferen-
    tial appellate review.
    Cite as: 581 U. S. ____ (2017)            7
    Opinion of the Court
    Today, nearly as uniformly, the Courts of Appeals apply
    the same deferential review to a district court’s decision as
    to whether to enforce an EEOC subpoena. Almost every
    Court of Appeals reviews such a decision for abuse of
    discretion. See, e.g., EEOC v. Kronos Inc., 
    620 F. 3d 287
    ,
    295–296 (CA3 2010); EEOC v. Randstad, 
    685 F. 3d 433
    ,
    442 (CA4 2012); EEOC v. Roadway Express, Inc., 
    261 F. 3d 634
    , 638 (CA6 2001); EEOC v. United Air Lines, Inc.,
    
    287 F. 3d 643
    , 649 (CA7 2002); EEOC v. Technocrest Sys-
    tems, Inc., 
    448 F. 3d 1035
    , 1038 (CA8 2006); EEOC v.
    Dillon Companies, Inc., 
    310 F. 3d 1271
    , 1274 (CA10 2002);
    EEOC v. Royal Caribbean Cruises, Ltd., 
    771 F. 3d 757
    ,
    760 (CA11 2014) (per curiam). As Judge Watford—writing
    for the panel below—recognized, the Ninth Circuit alone
    applies a more searching form of review. See 804 F. 3d, at
    1056, n. 3 (“Why we review questions of relevance and
    undue burden de novo is unclear”); see also EPA v. Alyeska
    Pipeline Serv. Co., 
    836 F. 2d 443
    , 445–446 (CA9 1988)
    (holding that de novo review applies). To be sure, the
    inquiry into the appropriate standard of review cannot be
    resolved by a head-counting exercise. But the “long his-
    tory of appellate practice” here, Pierce, 
    487 U. S., at 558
    ,
    carries significant persuasive weight.
    Second, basic principles of institutional capacity counsel
    in favor of deferential review. The decision whether to
    enforce an EEOC subpoena is a case-specific one that
    turns not on “a neat set of legal rules,” Illinois v. Gates,
    
    462 U. S. 213
    , 232 (1983), but instead on the application of
    broad standards to “multifarious, fleeting, special, narrow
    facts that utterly resist generalization,” Pierce, 
    487 U. S., at
    561–562 (internal quotation marks omitted). In the
    mine run of cases, the district court’s decision whether to
    enforce a subpoena will turn either on whether the evi-
    dence sought is relevant to the specific charge before it or
    whether the subpoena is unduly burdensome in light of
    the circumstances. Both tasks are well suited to a district
    8                        MCLANE CO. v. EEOC
    Opinion of the Court
    judge’s expertise. The decision whether evidence sought is
    relevant requires the district court to evaluate the rela-
    tionship between the particular materials sought and the
    particular matter under investigation—an analysis “vari-
    able in relation to the nature, purposes and scope of the
    inquiry.” Oklahoma Press Publishing Co. v. Walling, 
    327 U. S. 186
    , 209 (1946). Similarly, the decision whether a
    subpoena is overly burdensome turns on the nature of the
    materials sought and the difficulty the employer will face
    in producing them. These inquiries are “generally not
    amenable to broad per se rules,” Sprint/United Manage-
    ment Co. v. Mendelsohn, 
    552 U. S. 379
    , 387 (2008); rather,
    they are the kind of “fact-intensive, close calls” better
    suited to resolution by the district court than the court of
    appeals, Cooter & Gell v. Hartmarx Corp., 
    496 U. S. 384
    ,
    404 (1990) (internal quotation marks omitted).3
    Other functional considerations also show that abuse-of-
    discretion review is appropriate here. For one, district
    courts have considerable experience in other contexts
    making decisions similar—though not identical—to those
    they must make in this one. See Buford v. United States,
    
    532 U. S. 59
    , 66 (2001) (“[T]he comparatively greater
    expertise” of the district court may counsel in favor of
    deferential review). District courts decide, for instance,
    whether evidence is relevant at trial, Fed. Rule Evid. 401;
    whether pretrial criminal subpoenas are unreasonable in
    ——————
    3 To
    be sure, there are pure questions of law embedded in a district
    court’s decision to enforce or quash a subpoena. Whether a charge is
    “valid,” EEOC v. Shell Oil Co., 
    466 U. S. 54
    , 72, n. 26 (1984)—that is,
    legally sufficient—is a pure question of law. And the question whether
    a district court employed the correct standard of relevance, see 
    id.,
     at
    68–69—as opposed to how it applied that standard to the facts of a
    given case—is a question of law. But “applying a unitary abuse-of-
    discretion standard” does not shelter a district court that makes an
    error of law, because “[a] district court would necessarily abuse its
    discretion if it based its ruling on an erroneous view of the law.” Cooter
    & Gell v. Hartmarx Corp., 
    496 U. S. 384
    , 403, 405 (1990).

    scope, Fed. Rule Crim. Proc. 16(c)(2); and more. These
    decisions are not the same as the decisions a district court
    must make in enforcing an administrative subpoena. But
    they are similar enough to give the district court the “in-
    stitutional advantag[e],” Buford, 
    532 U. S., at 64
    , that
    comes with greater experience. For another, as we noted
    in Cooter & Gell, deferential review “streamline[s] the
    litigation process by freeing appellate courts from the duty
    of reweighing evidence and reconsidering facts already
    weighed and considered by the district court,” 
    496 U. S., at
    404—a particularly important consideration in a “satel-
    lite” proceeding like this one, ibid., designed only to facili-
    tate the EEOC’s investigation.
    B
    Amicus’ arguments to the contrary have aided our con-
    sideration of this case. But they do not persuade us that
    de novo review is appropriate.
    Amicus’ central argument is that the decision whether a
    subpoena should be enforced does not require the exercise
    of discretion on the part of the district court, and so it
    should not be reviewed for abuse of discretion. On amicus’
    view, the district court’s primary role is to test the legal
    sufficiency of the subpoena, not to weigh whether it should
    be enforced as a substantive matter. Cf. Shell Oil, 
    466 U. S., at 72, n. 26
     (rejecting the argument that the district
    court should assess the validity of the underlying claim in
    a proceeding to enforce a subpoena). Even accepting
    amicus’ view of the district court’s task, however, this
    understanding of abuse-of-discretion review is too narrow.
    As commentators have observed, abuse-of-discretion re-
    view is employed not only where a decisionmaker has “a
    wide range of choice as to what he decides, free from the
    constraints which characteristically attach whenever legal
    rules enter the decision[making] process”; it is also em-
    ployed where the trial judge’s decision is given “an unu-
    10                  MCLANE CO. v. EEOC
    Opinion of the Court
    sual amount of insulation from appellate revision” for func-
    tional reasons. Rosenberg, Judicial Discretion of the Trial
    Court, Viewed From Above, 
    22 Syracuse L. Rev. 635
    , 637
    (1971); see also 22 C. Wright & K. Graham, Federal Prac-
    tice and Procedure §5166.1 (2d ed. 2012). And as we have
    explained, it is in large part due to functional concerns
    that we conclude the district court’s decision should be
    reviewed for abuse of discretion. Even if the district
    court’s decision can be characterized in the way that ami-
    cus suggests, that characterization would not be incon-
    sistent with abuse-of-discretion review.
    Nor are we persuaded by amicus’ remaining arguments.
    Amicus argues that affording deferential review to a dis-
    trict court’s decision would clash with Court of Appeals
    decisions instructing district courts to defer themselves to
    the EEOC’s determination that evidence is relevant to the
    charge at issue. See Director, Office of Thrift Supervision,
    v. Vinson & Elkins, LLP, 
    124 F. 3d 1304
    , 1307 (CADC
    1997) (district courts should defer to agency appraisals of
    relevance unless they are “obviously wrong”); EEOC v.
    Lockheed Martin Corp., Aero & Naval Systems, 
    116 F. 3d 110
    , 113 (CA4 1997) (same). In amicus’ view, it is “analyt-
    ically impossible” for the court of appeals to defer to the
    district court if the district court must itself defer to the
    agency. Tr. of Oral Arg. 29. We think the better reading
    of those cases is that they rest on the established rule that
    the term “relevant” be understood “generously” to permit
    the EEOC “access to virtually any material that might
    cast light on the allegations against the employer.” Shell
    Oil, 
    466 U. S., at
    68–69. A district court deciding whether
    evidence is “relevant” under Title VII need not defer to the
    EEOC’s decision on that score; it must simply answer the
    question cognizant of the agency’s broad authority to seek
    and obtain evidence. Because the statute does not set up
    any scheme of double deference, amicus’ arguments as to
    the infirmities of such a scheme are misplaced.

    Opinion of the Court
    Nor do we agree that, as amicus suggests, the constitu-
    tional underpinnings of the Shell Oil standard require a
    different result. To be sure, we have described a subpoena
    as a “ ‘constructive’ search,” Oklahoma Press, 
    327 U. S., at 202
    , and implied that the Fourth Amendment is the
    source of the requirement that a subpoena not be “too
    indefinite,” Morton Salt, 
    338 U. S., at 652
    . But not every
    decision that touches on the Fourth Amendment is subject
    to searching review. Subpoenas in a wide variety of other
    contexts also implicate the privacy interests protected by
    the Fourth Amendment, but courts routinely review the
    enforcement of such subpoenas for abuse of discretion.
    See, e.g., United States v. Nixon, 
    418 U. S. 683
    , 702 (1974)
    (pretrial subpoenas duces tecum); In re Grand Jury Sub-
    poena, 
    696 F. 3d 428
    , 432 (CA5 2012) (grand jury subpoe-
    nas); In re Grand Jury Proceedings, 
    616 F. 3d 1186
    , 1201
    (CA10 2010) (same). And this Court has emphasized that
    courts should pay “great deference” to a magistrate judge’s
    determination of probable cause, Gates, 
    462 U. S., at 236
    (internal quotation marks omitted)—a decision more akin
    to a district court’s preenforcement review of a subpoena
    than the warrantless searches and seizures we considered
    in Ornelas v. United States, 
    517 U. S. 690
     (1996), on which
    amicus places great weight. The constitutional pedigree of
    Shell Oil does not change our view of the correct standard
    of review.
    III
    For these reasons, a district court’s decision to enforce
    an EEOC subpoena should be reviewed for abuse of discre-
    tion, not de novo.
    The United States also argues that the judgment below
    can be affirmed because it is clear that the District Court
    abused its discretion. But “we are a court of review, not of
    first view,” Cutter v. Wilkinson, 
    544 U. S. 709
    , 718, n. 7
    (2005), and the Court of Appeals has not had the chance to
    12                  MCLANE CO. v. EEOC
    Opinion of the Court
    review the District Court’s decision under the appropriate
    standard. That task is for the Court of Appeals in the first
    instance. As part of its analysis, the Court of Appeals may
    also consider, as and to the extent it deems appropriate,
    any arguments made by McLane regarding the burdens
    imposed by the subpoena.
    The judgment of the Court of Appeals is hereby vacated,
    and the case is remanded for further proceedings con-
    sistent with this opinion.
    It is so ordered.

    MCLANE COMPANY, INC., PETITIONER v. EQUAL
    EMPLOYMENT OPPORTUNITY COMMISSION
    ON WRIT OF CERTIORARI TO THE UNITED STATES COURT OF
    APPEALS FOR THE NINTH CIRCUIT
    [April 3, 2017]
    JUSTICE GINSBURG, concurring in part and dissenting in
    part.
    While I agree with the Court that “abuse of discretion”
    is generally the proper review standard for district court
    decisions reviewing agency subpoenas, I would neverthe-
    less affirm the Ninth Circuit’s judgment in this case. As
    the Court of Appeals explained, the District Court’s re-
    fusal to enforce the Equal Employment Opportunity
    Commission’s (EEOC) subpoena for pedigree information
    rested on a legal error. Lower court resolution of a ques-
    tion of law is ordinarily reviewable de novo on appeal.
    Highmark Inc. v. Allcare Health Management System,
    Inc., 572 U. S. ___, ___, and n. 2 (2014) (slip op., at 4, and
    n. 2). According to the District Court, it was not yet “nec-
    essary [for the EEOC] to seek such information.” 
    2012 WL 5868959
    , *6 (D Ariz., Nov. 19, 2012). As the Ninth Circuit
    correctly conveyed, however: “The EEOC does not have to
    show a ‘particularized necessity of access, beyond a show-
    ing of mere relevance,’ to obtain evidence.” 
    804 F. 3d 1051
    , 1057 (2015) (quoting University of Pa. v. EEOC, 
    493 U. S. 182
    , 188 (1990)). Because the District Court erred as
    a matter of law in demanding that the EEOC show more
    than relevance in order to gain enforcement of its sub-
    poena, I would not disturb the Court of Appeals’ judgment.
