    WAL-MART STORES, INC. v. DUKES ET AL.
    CERTIORARI TO THE UNITED STATES COURT OF APPEALS FOR
    THE NINTH CIRCUIT
    No. 10–277.      Argued March 29, 2011—Decided June 20, 2011
    Respondents, current or former employees of petitioner Wal-Mart,
    sought judgment against the company for injunctive and declaratory
    relief, punitive damages, and backpay, on behalf of themselves and a
    nationwide class of some 1.5 million female employees, because of
    Wal-Mart’s alleged discrimination against women in violation of Title
    VII of the Civil Rights Act of 1964. They claim that local managers
    exercise their discretion over pay and promotions disproportionately
    in favor of men, which has an unlawful disparate impact on female
    employees; and that Wal-Mart’s refusal to cabin its managers’ au
    thority amounts to disparate treatment. The District Court certified
    the class, finding that respondents satisfied Federal Rule of Civil
    Procedure 23(a), and Rule 23(b)(2)’s requirement of showing that “the
    party opposing the class has acted or refused to act on grounds that
    apply generally to the class, so that final injunctive relief or corre
    sponding declaratory relief is appropriate respecting the class as a
    whole.” The Ninth Circuit substantially affirmed, concluding, inter
    alia, that respondents met Rule 23(a)(2)’s commonality requirement
    and that their backpay claims could be certified as part of a (b)(2)
    class because those claims did not predominate over the declaratory
    and injunctive relief requests. It also ruled that the class action
    could be manageably tried without depriving Wal-Mart of its right to
    present its statutory defenses if the District Court selected a random
    set of claims for valuation and then extrapolated the validity and
    value of the untested claims from the sample set.
    Held:
    1. The certification of the plaintiff class was not consistent with
    Rule 23(a). Pp. 8–20.
    (a) Rule 23(a)(2) requires a party seeking class certification to
    2                 WAL-MART STORES, INC. v. DUKES
    Syllabus
    prove that the class has common “questions of law or fact.” Their
    claims must depend upon a common contention of such a nature that
    it is capable of classwide resolution—which means that determina
    tion of its truth or falsity will resolve an issue that is central to the
    validity of each one of the claims in one stroke. Here, proof of com
    monality necessarily overlaps with respondents’ merits contention
    that Wal-Mart engages in a pattern or practice of discrimination.
    The crux of a Title VII inquiry is “the reason for a particular em
    ployment decision,” Cooper v. Federal Reserve Bank of Richmond, 
    467 U. S. 867
    , 876, and respondents wish to sue for millions of employ
    ment decisions at once. Without some glue holding together the al
    leged reasons for those decisions, it will be impossible to say that ex
    amination of all the class members’ claims will produce a common
    answer to the crucial discrimination question. Pp. 8–12.
    (b) General Telephone Co. of Southwest v. Falcon, 
    457 U. S. 147
    ,
    describes the proper approach to commonality. On the facts of this
    case, the conceptual gap between an individual’s discrimination claim
    and “the existence of a class of persons who have suffered the same
    injury,” 
    id.,
     at 157–158, must be bridged by “[s]ignificant proof that
    an employer operated under a general policy of discrimination,” 
    id., at 159, n. 15
    . Such proof is absent here. Wal-Mart’s announced pol
    icy forbids sex discrimination, and the company has penalties for de
    nials of equal opportunity. Respondents’ only evidence of a general
    discrimination policy was a sociologist’s analysis asserting that Wal-
    Mart’s corporate culture made it vulnerable to gender bias. But be
    cause he could not estimate what percent of Wal-Mart employment
    decisions might be determined by stereotypical thinking, his testi
    mony was worlds away from “significant proof” that Wal-Mart “oper
    ated under a general policy of discrimination.” Pp. 12–14.
    (c) The only corporate policy that the plaintiffs’ evidence convinc
    ingly establishes is Wal-Mart’s “policy” of giving local supervisors
    discretion over employment matters. While such a policy could be
    the basis of a Title VII disparate-impact claim, recognizing that a
    claim “can” exist does not mean that every employee in a company
    with that policy has a common claim. In a company of Wal-Mart’s
    size and geographical scope, it is unlikely that all managers would
    exercise their discretion in a common way without some common di
    rection. Respondents’ attempt to show such direction by means of
    statistical and anecdotal evidence falls well short. Pp. 14–20.
    2. Respondents’ backpay claims were improperly certified under
    Rule 23(b)(2). Pp. 20–27.
    (a) Claims for monetary relief may not be certified under Rule
    23(b)(2), at least where the monetary relief is not incidental to the
    requested injunctive or declaratory relief. It is unnecessary to decide
    Cite as: 564 U. S. ____ (2011)                      3
    Syllabus
    whether monetary claims can ever be certified under the Rule be
    cause, at a minimum, claims for individualized relief, like backpay,
    are excluded. Rule 23(b)(2) applies only when a single, indivisible
    remedy would provide relief to each class member. The Rule’s his
    tory and structure indicate that individualized monetary claims be
    long instead in Rule 23(b)(3), with its procedural protections of pre
    dominance, superiority, mandatory notice, and the right to opt out.
    Pp. 20–23.
    (b) Respondents nonetheless argue that their backpay claims
    were appropriately certified under Rule 23(b)(2) because those claims
    do not “predominate” over their injunctive and declaratory relief re
    quests. That interpretation has no basis in the Rule’s text and does
    obvious violence to the Rule’s structural features. The mere “pre
    dominance” of a proper (b)(2) injunctive claim does nothing to justify
    eliminating Rule 23(b)(3)’s procedural protections, and creates incen
    tives for class representatives to place at risk potentially valid mone
    tary relief claims. Moreover, a district court would have to reevalu
    ate the roster of class members continuously to excise those who
    leave their employment and become ineligible for classwide injunc
    tive or declaratory relief. By contrast, in a properly certified (b)(3)
    class action for backpay, it would be irrelevant whether the plaintiffs
    are still employed at Wal-Mart. It follows that backpay claims
    should not be certified under Rule 23(b)(2). Pp. 23–26.
    (c) It is unnecessary to decide whether there are any forms of “in
    cidental” monetary relief that are consistent with the above interpre
    tation of Rule 23(b)(2) and the Due Process Clause because respon
    dents’ backpay claims are not incidental to their requested
    injunction. Wal-Mart is entitled to individualized determinations of
    each employee’s eligibility for backpay. Once a plaintiff establishes a
    pattern or practice of discrimination, a district court must usually
    conduct “additional proceedings . . . to determine the scope of indi
    vidual relief.” Teamsters v. United States, 
    431 U. S. 324
    , 361. The
    company can then raise individual affirmative defenses and demon
    strate that its action was lawful. 
    Id., at 362
    . The Ninth Circuit erred
    in trying to replace such proceedings with Trial by Formula. Because
    Rule 23 cannot be interpreted to “abridge, enlarge or modify any sub
    stantive right,” 
    28 U. S. C. §2072
    (b), a class cannot be certified on the
    premise that Wal-Mart will not be entitled to litigate its statutory de
    fenses to individual claims. Pp. 26–27.

    WAL-MART STORES, INC., PETITIONER v.
    BETTY DUKES ET AL.
    ON WRIT OF CERTIORARI TO THE UNITED STATES COURT OF
    APPEALS FOR THE NINTH CIRCUIT
    [June 20, 2011]
    JUSTICE SCALIA delivered the opinion of the Court.
    We are presented with one of the most expansive class
    actions ever. The District Court and the Court of Appeals
    approved the certification of a class comprising about one
    and a half million plaintiffs, current and former female
    employees of petitioner Wal-Mart who allege that the
    discretion exercised by their local supervisors over pay
    and promotion matters violates Title VII by discriminat
    ing against women. In addition to injunctive and declara
    tory relief, the plaintiffs seek an award of backpay. We
    consider whether the certification of the plaintiff class
    was consistent with Federal Rules of Civil Procedure 23(a)
    and (b)(2).
    I
    A
    Petitioner Wal-Mart is the Nation’s largest private
    employer. It operates four types of retail stores through
    out the country: Discount Stores, Supercenters, Neighbor
    hood Markets, and Sam’s Clubs. Those stores are divided
    into seven nationwide divisions, which in turn comprise 41
    regions of 80 to 85 stores apiece. Each store has between
    2             WAL-MART STORES, INC. v. DUKES
    Opinion of the Court
    40 and 53 separate departments and 80 to 500 staff posi
    tions. In all, Wal-Mart operates approximately 3,400
    stores and employs more than one million people.
    Pay and promotion decisions at Wal-Mart are generally
    committed to local managers’ broad discretion, which is
    exercised “in a largely subjective manner.” 222 F. R. D.
    137, 145 (ND Cal. 2004). Local store managers may in
    crease the wages of hourly employees (within limits) with
    only limited corporate oversight. As for salaried employ
    ees, such as store managers and their deputies, higher
    corporate authorities have discretion to set their pay with
    in preestablished ranges.
    Promotions work in a similar fashion. Wal-Mart per
    mits store managers to apply their own subjective criteria
    when selecting candidates as “support managers,” which is
    the first step on the path to management. Admission to
    Wal-Mart’s management training program, however, does
    require that a candidate meet certain objective criteria,
    including an above-average performance rating, at least
    one year’s tenure in the applicant’s current position, and a
    willingness to relocate. But except for those requirements,
    regional and district managers have discretion to use their
    own judgment when selecting candidates for management
    training. Promotion to higher office—e.g., assistant man
    ager, co-manager, or store manager—is similarly at the
    discretion of the employee’s superiors after prescribed
    objective factors are satisfied.
    B
    The named plaintiffs in this lawsuit, representing the
    1.5 million members of the certified class, are three cur
    rent or former Wal-Mart employees who allege that the
    company discriminated against them on the basis of their
    sex by denying them equal pay or promotions, in violation
    of Title VII of the Civil Rights Act of 1964, 
    78 Stat. 253
    , as

    Opinion of the Court
    amended, 42 U. S. C. §2000e–1 et seq.1
    Betty Dukes began working at a Pittsburg, California,
    Wal-Mart in 1994. She started as a cashier, but later
    sought and received a promotion to customer service man
    ager. After a series of disciplinary violations, however,
    Dukes was demoted back to cashier and then to greeter.
    Dukes concedes she violated company policy, but contends
    that the disciplinary actions were in fact retaliation for
    invoking internal complaint procedures and that male
    employees have not been disciplined for similar infrac
    tions. Dukes also claims two male greeters in the Pitts
    burg store are paid more than she is.
    Christine Kwapnoski has worked at Sam’s Club stores
    in Missouri and California for most of her adult life. She
    has held a number of positions, including a supervisory
    position. She claims that a male manager yelled at her
    frequently and screamed at female employees, but not at
    men. The manager in question “told her to ‘doll up,’ to
    wear some makeup, and to dress a little better.” App.
    1003a.
    The final named plaintiff, Edith Arana, worked at a
    Wal-Mart store in Duarte, California, from 1995 to 2001.
    In 2000, she approached the store manager on more than
    one occasion about management training, but was brushed
    off. Arana concluded she was being denied opportunity for
    advancement because of her sex. She initiated internal
    complaint procedures, whereupon she was told to apply
    directly to the district manager if she thought her store
    manager was being unfair. Arana, however, decided
    against that and never applied for management training
    again. In 2001, she was fired for failure to comply with
    Wal-Mart’s timekeeping policy.
    These plaintiffs, respondents here, do not allege that
    ——————
    1 The complaint included seven named plaintiffs, but only three re
    main part of the certified class as narrowed by the Court of Appeals.
    4            WAL-MART STORES, INC. v. DUKES
    Opinion of the Court
    Wal-Mart has any express corporate policy against the
    advancement of women. Rather, they claim that their
    local managers’ discretion over pay and promotions is
    exercised disproportionately in favor of men, leading to an
    unlawful disparate impact on female employees, see 42
    U. S. C. §2000e–2(k). And, respondents say, because Wal-
    Mart is aware of this effect, its refusal to cabin its manag
    ers’ authority amounts to disparate treatment, see
    §2000e–2(a). Their complaint seeks injunctive and de
    claratory relief, punitive damages, and backpay. It does
    not ask for compensatory damages.
    Importantly for our purposes, respondents claim that
    the discrimination to which they have been subjected is
    common to all Wal-Mart’s female employees. The basic
    theory of their case is that a strong and uniform “corporate
    culture” permits bias against women to infect, perhaps
    subconsciously, the discretionary decisionmaking of each
    one of Wal-Mart’s thousands of managers—thereby mak
    ing every woman at the company the victim of one com
    mon discriminatory practice. Respondents therefore wish
    to litigate the Title VII claims of all female employees at
    Wal-Mart’s stores in a nationwide class action.
    C
    Class certification is governed by Federal Rule of Civil
    Procedure 23. Under Rule 23(a), the party seeking certifi
    cation must demonstrate, first, that:
    “(1) the class is so numerous that joinder of all mem-
    bers is impracticable,
    “(2) there are questions of law or fact common to the
    class,
    “(3) the claims or defenses of the representative par
    ties are typical of the claims or defenses of the class,
    and
    “(4) the representative parties will fairly and ade
    quately protect the interests of the class” (paragraph
    Cite as: 564 U. S. ____ (2011)                      5
    Opinion of the Court
    breaks added).
    Second, the proposed class must satisfy at least one of the
    three requirements listed in Rule 23(b). Respondents rely
    on Rule 23(b)(2), which applies when “the party opposing
    the class has acted or refused to act on grounds that apply
    generally to the class, so that final injunctive relief or
    corresponding declaratory relief is appropriate respecting
    the class as a whole.”2
    Invoking these provisions, respondents moved the Dis
    trict Court to certify a plaintiff class consisting of “ ‘[a]ll
    women employed at any Wal-Mart domestic retail store
    at any time since December 26, 1998, who have been or
    may be subjected to Wal-Mart’s challenged pay and man
    agement track promotions policies and practices.’ ” 222
    F. R. D., at 141–142 (quoting Plaintiff ’s Motion for Class
    Certification in case No. 3:01–cv–02252–CRB (ND Cal.),
    Doc. 99, p. 37). As evidence that there were indeed “ques
    tions of law or fact common to” all the women of Wal-Mart,
    as Rule 23(a)(2) requires, respondents relied chiefly on
    three forms of proof: statistical evidence about pay and
    promotion disparities between men and women at the
    company, anecdotal reports of discrimination from about
    120 of Wal-Mart’s female employees, and the testimony of
    a sociologist, Dr. William Bielby, who conducted a “social
    ——————
    2 Rule 23(b)(1) allows a class to be maintained where “prosecuting
    separate actions by or against individual class members would create a
    risk of ” either “(A) inconsistent or varying adjudications,” or “(B)
    adjudications . . . that, as a practical matter, would be dispositive of the
    interests of the other members not parties to the individual adjudica
    tions or would substantially impair or impeded their ability to protect
    their interests.” Rule 23(b)(3) states that a class may be maintained
    where “questions of law or fact common to class members predominate
    over any questions affecting only individual members,” and a class
    action would be “superior to other available methods for fairly and
    efficiently adjudicating the controversy.” The applicability of these
    provisions to the plaintiff class is not before us.

    framework analysis” of Wal-Mart’s “culture” and person
    nel practices, and concluded that the company was “vul
    nerable” to gender discrimination. 
    603 F. 3d 571
    , 601
    (CA9 2010) (en banc).
    Wal-Mart unsuccessfully moved to strike much of this
    evidence. It also offered its own countervailing statistical
    and other proof in an effort to defeat Rule 23(a)’s require
    ments of commonality, typicality, and adequate represen
    tation. Wal-Mart further contended that respondents’
    monetary claims for backpay could not be certified under
    Rule 23(b)(2), first because that Rule refers only to injunc
    tive and declaratory relief, and second because the back
    pay claims could not be manageably tried as a class with
    out depriving Wal-Mart of its right to present certain
    statutory defenses. With one limitation not relevant here,
    the District Court granted respondents’ motion and certi
    fied their proposed class.3
    D
    A divided en banc Court of Appeals substantially af
    firmed the District Court’s certification order. 
    603 F. 3d 571
    . The majority concluded that respondents’ evidence of
    commonality was sufficient to “raise the common question
    whether Wal-Mart’s female employees nationwide were
    subjected to a single set of corporate policies (not merely a
    number of independent discriminatory acts) that may
    have worked to unlawfully discriminate against them in
    violation of Title VII.” 
    Id., at 612
     (emphasis deleted). It
    also agreed with the District Court that the named plain
    tiffs’ claims were sufficiently typical of the class as a whole
    ——————
    3 The District Court excluded backpay claims based on promotion
    opportunities that had not been publicly posted, for the reason that no
    applicant data could exist for such positions. 222 F. R. D. 137, 182 (ND
    Cal. 2004). It also decided to afford class members notice of the ac
    tion and the right to opt-out of the class with respect to respondents’
    punitive-damages claim. 
    Id., at 173
    .

    Opinion of the Court
    to satisfy Rule 23(a)(3), and that they could serve as ade
    quate class representatives, see Rule 23(a)(4). 
    Id.,
     at 614–
    615. With respect to the Rule 23(b)(2) question, the Ninth
    Circuit held that respondents’ backpay claims could be
    certified as part of a (b)(2) class because they did not
    “predominat[e]” over the requests for declaratory and
    injunctive relief, meaning they were not “superior in
    strength, influence, or authority” to the nonmonetary
    claims. 
    Id., at 616
     (internal quotation marks omitted).4
    Finally, the Court of Appeals determined that the action
    could be manageably tried as a class action because the
    District Court could adopt the approach the Ninth Circuit
    approved in Hilao v. Estate of Marcos, 
    103 F. 3d 767
    , 782–
    787 (1996). There compensatory damages for some 9,541
    class members were calculated by selecting 137 claims at
    random, referring those claims to a special master for
    valuation, and then extrapolating the validity and value of
    the untested claims from the sample set. See 603 F. 3d, at
    625–626. The Court of Appeals “s[aw] no reason why a
    similar procedure to that used in Hilao could not be em
    ployed in this case.” Id., at 627. It would allow Wal-Mart
    “to present individual defenses in the randomly selected
    ‘sample cases,’ thus revealing the approximate percentage
    of class members whose unequal pay or nonpromotion was
    due to something other than gender discrimination.”
    Ibid., n. 56 (emphasis deleted).
    ——————
    4 To  enable that result, the Court of Appeals trimmed the (b)(2) class
    in two ways: First, it remanded that part of the certification order
    which included respondents’ punitive-damages claim in the (b)(2) class,
    so that the District Court might consider whether that might cause the
    monetary relief to predominate. 603 F. 3d, at 621. Second, it accepted
    in part Wal-Mart’s argument that since class members whom it no
    longer employed had no standing to seek injunctive or declaratory
    relief, as to them monetary claims must predominate. It excluded from
    the certified class “those putative class members who were no longer
    Wal-Mart employees at the time Plaintiffs’ complaint was filed,” id., at
    623 (emphasis added).

    Opinion of the Court
    We granted certiorari. 562 U. S. ___ (2010).
    II
    The class action is “an exception to the usual rule that
    litigation is conducted by and on behalf of the individual
    named parties only.” Califano v. Yamasaki, 
    442 U. S. 682
    ,
    700–701 (1979). In order to justify a departure from that
    rule, “a class representative must be part of the class and
    ‘possess the same interest and suffer the same injury’ as
    the class members.” East Tex. Motor Freight System,
    Inc. v. Rodriguez, 
    431 U. S. 395
    , 403 (1977) (quoting
    Schlesinger v. Reservists Comm. to Stop the War, 
    418 U. S. 208
    , 216 (1974)). Rule 23(a) ensures that the named
    plaintiffs are appropriate representatives of the class
    whose claims they wish to litigate. The Rule’s four
    requirements—numerosity, commonality, typicality, and
    adequate representation—“effectively ‘limit the class
    claims to those fairly encompassed by the named plain
    tiff ’s claims.’ ” General Telephone Co. of Southwest v.
    Falcon, 
    457 U. S. 147
    , 156 (1982) (quoting General Tele
    phone Co. of Northwest v. EEOC, 
    446 U. S. 318
    , 330
    (1980)).
    A
    The crux of this case is commonality—the rule requiring
    a plaintiff to show that “there are questions of law or fact
    common to the class.” Rule 23(a)(2).5 That language is
    ——————
    5 We have previously stated in this context that “[t]he commonality
    and typicality requirements of Rule 23(a) tend to merge. Both serve as
    guideposts for determining whether under the particular circumstances
    maintenance of a class action is economical and whether the named
    plaintiff’s claim and the class claims are so interrelated that the inter
    ests of the class members will be fairly and adequately protected in
    their absence. Those requirements therefore also tend to merge with
    the adequacy-of-representation requirement, although the latter
    requirement also raises concerns about the competency of class counsel
    and conflicts of interest.” General Telephone Co. of Southwest v. Fal

    easy to misread, since “[a]ny competently crafted class
    complaint literally raises common ‘questions.’ ” Nagareda,
    Class Certification in the Age of Aggregate Proof, 84
    N. Y. U. L. Rev. 97, 131–132 (2009). For example: Do all
    of us plaintiffs indeed work for Wal-Mart? Do our manag
    ers have discretion over pay? Is that an unlawful em
    ployment practice? What remedies should we get? Recit
    ing these questions is not sufficient to obtain class
    certification. Commonality requires the plaintiff to dem
    onstrate that the class members “have suffered the same
    injury,” Falcon, supra, at 157. This does not mean merely
    that they have all suffered a violation of the same pro
    vision of law. Title VII, for example, can be violated in
    many ways—by intentional discrimination, or by hiring
    and promotion criteria that result in disparate impact,
    and by the use of these practices on the part of many
    different superiors in a single company. Quite obviously,
    the mere claim by employees of the same company that
    they have suffered a Title VII injury, or even a disparate
    impact Title VII injury, gives no cause to believe that all
    their claims can productively be litigated at once. Their
    claims must depend upon a common contention—for ex
    ample, the assertion of discriminatory bias on the part of
    the same supervisor. That common contention, moreover,
    must be of such a nature that it is capable of classwide
    resolution—which means that determination of its truth
    or falsity will resolve an issue that is central to the valid
    ity of each one of the claims in one stroke.

    the commonality question, however, it is unnecessary to resolve
    whether respondents have satisfied the typicality and adequate
    representation requirements of Rule 23(a).

    erate common answers apt to drive the resolution of
    the litigation. Dissimilarities within the proposed
    class are what have the potential to impede the gen
    eration of common answers.” Nagareda, supra, at 132.
    Rule 23 does not set forth a mere pleading standard. A
    party seeking class certification must affirmatively dem
    onstrate his compliance with the Rule—that is, he must be
    prepared to prove that there are in fact sufficiently nu
    merous parties, common questions of law or fact, etc. We
    recognized in Falcon that “sometimes it may be necessary
    for the court to probe behind the pleadings before coming
    to rest on the certification question,” 
    457 U. S., at 160
    , and
    that certification is proper only if “the trial court is satis
    fied, after a rigorous analysis, that the prerequisites of
    Rule 23(a) have been satisfied,” 
    id., at 161
    ; see 
    id., at 160
    (“[A]ctual, not presumed, conformance with Rule 23(a)
    remains . . . indispensable”). Frequently that “rigorous
    analysis” will entail some overlap with the merits of
    the plaintiff ’s underlying claim. That cannot be helped.
    “ ‘[T]he class determination generally involves considera
    tions that are enmeshed in the factual and legal issues
    comprising the plaintiff ’s cause of action.’ ” Falcon, supra,
    at 160 (quoting Coopers & Lybrand v. Livesay, 
    437 U. S. 463
    , 469 (1978); some internal quotation marks omitted).6

    6 A statement in one of our prior cases, Eisen v. Carlisle & Jacquelin,
    
    417 U. S. 156
    , 177 (1974), is sometimes mistakenly cited to the con
    trary: “We find nothing in either the language or history of Rule 23 that
    gives a court any authority to conduct a preliminary inquiry into the
    merits of a suit in order to determine whether it may be maintained as
    a class action.” But in that case, the judge had conducted a preliminary
    inquiry into the merits of a suit, not in order to determine the propriety
    of certification under Rules 23(a) and (b) (he had already done that, see
    
    id., at 165
    ), but in order to shift the cost of notice required by Rule
    23(c)(2) from the plaintiff to the defendants. To the extent the quoted
    statement goes beyond the permissibility of a merits inquiry for any
    other pretrial purpose, it is the purest dictum and is contradicted by
    our other cases.

    Opinion of the Court
    Nor is there anything unusual about that consequence:
    The necessity of touching aspects of the merits in order to
    resolve preliminary matters, e.g., jurisdiction and venue,
    is a familiar feature of litigation. See Szabo v. Bridgeport
    Machines, Inc., 
    249 F. 3d 672
    , 676–677 (CA7 2001)
    (Easterbrook, J.).
    In this case, proof of commonality necessarily overlaps
    with respondents’ merits contention that Wal-Mart en
    gages in a pattern or practice of discrimination.7 That is so
    because, in resolving an individual’s Title VII claim, the
    crux of the inquiry is “the reason for a particular employ
    ment decision,” Cooper v. Federal Reserve Bank of Rich
    mond, 
    467 U. S. 867
    , 876 (1984). Here respondents wish

    Perhaps the most common example of considering a merits question
    at the Rule 23 stage arises in class-action suits for securities fraud.
    Rule 23(b)(3)’s requirement that “questions of law or fact common to
    class members predominate over any questions affecting only individ
    ual members” would often be an insuperable barrier to class certifica
    tion, since each of the individual investors would have to prove reliance
    on the alleged misrepresentation. But the problem dissipates if the
    plaintiffs can establish the applicability of the so-called “fraud on the
    market” presumption, which says that all traders who purchase stock
    in an efficient market are presumed to have relied on the accuracy of a
    company’s public statements. To invoke this presumption, the plain
    tiffs seeking 23(b)(3) certification must prove that their shares were
    traded on an efficient market, Erica P. John Fund, Inc. v. Halliburton
    Co., 563 U. S. ___, ___ (2011) (slip op., at 5), an issue they will surely
    have to prove again at trial in order to make out their case on the
    merits.
    7 In a pattern-or-practice case, the plaintiff tries to “establish by a
    preponderance of the evidence that . . . discrimination was the com
    pany’s standard operating procedure[,] the regular rather than the
    unusual practice.” Teamsters v. United States, 
    431 U. S. 324
    , 358
    (1977); see also Franks v. Bowman Transp. Co., 
    424 U. S. 747
    , 772
    (1976). If he succeeds, that showing will support a rebuttable inference
    that all class members were victims of the discriminatory practice, and
    will justify “an award of prospective relief,” such as “an injunctive order
    against the continuation of the discriminatory practice.” Teamsters,

    Opinion of the Court
    to sue about literally millions of employment decisions at
    once. Without some glue holding the alleged reasons for
    all those decisions together, it will be impossible to say
    that examination of all the class members’ claims for relief
    will produce a common answer to the crucial question why
    was I disfavored.
    B
    This Court’s opinion in Falcon describes how the com
    monality issue must be approached. There an employee
    who claimed that he was deliberately denied a promotion
    on account of race obtained certification of a class compris
    ing all employees wrongfully denied promotions and all
    applicants wrongfully denied jobs. 
    457 U. S., at 152
    . We
    rejected that composite class for lack of commonality and
    typicality, explaining:
    “Conceptually, there is a wide gap between (a) an in
    dividual’s claim that he has been denied a promotion
    [or higher pay] on discriminatory grounds, and his
    otherwise unsupported allegation that the company
    has a policy of discrimination, and (b) the existence of
    a class of persons who have suffered the same injury
    as that individual, such that the individual’s claim
    and the class claim will share common questions of
    law or fact and that the individual’s claim will be typi
    cal of the class claims.” 
    Id.,
     at 157–158.
    Falcon suggested two ways in which that conceptual gap
    might be bridged. First, if the employer “used a biased
    testing procedure to evaluate both applicants for employ
    ment and incumbent employees, a class action on behalf of
    every applicant or employee who might have been preju
    diced by the test clearly would satisfy the commonality
    and typicality requirements of Rule 23(a).” 
    Id., at 159, n. 15
    . Second, “[s]ignificant proof that an employer oper
    ated under a general policy of discrimination conceivably
    Cite as: 564 U. S. ____ (2011)           13
    Opinion of the Court
    could justify a class of both applicants and employees
    if the discrimination manifested itself in hiring and pro
    motion practices in the same general fashion, such as
    through entirely subjective decisionmaking processes.”
    
    Ibid.
     We think that statement precisely describes respon
    dents’ burden in this case. The first manner of bridging
    the gap obviously has no application here; Wal-Mart has
    no testing procedure or other companywide evaluation
    method that can be charged with bias. The whole point of
    permitting discretionary decisionmaking is to avoid evalu
    ating employees under a common standard.
    The second manner of bridging the gap requires “signifi
    cant proof ” that Wal-Mart “operated under a general
    policy of discrimination.” That is entirely absent here.
    Wal-Mart’s announced policy forbids sex discrimination,
    see App. 1567a–1596a, and as the District Court recog
    nized the company imposes penalties for denials of equal
    employment opportunity, 222 F. R. D., at 154. The only
    evidence of a “general policy of discrimination” respon
    dents produced was the testimony of Dr. William Bielby,
    their sociological expert. Relying on “social framework”
    analysis, Bielby testified that Wal-Mart has a “strong
    corporate culture,” that makes it “ ‘vulnerable’ ” to “gender
    bias.” 
    Id., at 152
    . He could not, however, “determine with
    any specificity how regularly stereotypes play a meaning
    ful role in employment decisions at Wal-Mart. At his
    deposition . . . Dr. Bielby conceded that he could not calcu
    late whether 0.5 percent or 95 percent of the employment
    decisions at Wal-Mart might be determined by stereotyped
    thinking.” 222 F. R. D. 189, 192 (ND Cal. 2004). The
    parties dispute whether Bielby’s testimony even met the
    standards for the admission of expert testimony under
    Federal Rule of Civil Procedure 702 and our Daubert case,
    see Daubert v. Merrell Dow Pharmaceuticals, Inc., 509
    14               WAL-MART STORES, INC. v. DUKES
    Opinion of the Court
    U. S. 579 (1993).8 The District Court concluded that
    Daubert did not apply to expert testimony at the certifica
    tion stage of class-action proceedings. 222 F. R. D., at 191.
    We doubt that is so, but even if properly considered,
    Bielby’s testimony does nothing to advance respondents’
    case. “[W]hether 0.5 percent or 95 percent of the employ
    ment decisions at Wal-Mart might be determined by
    stereotyped thinking” is the essential question on which
    respondents’ theory of commonality depends. If Bielby
    admittedly has no answer to that question, we can safely
    disregard what he has to say. It is worlds away from
    “significant proof ” that Wal-Mart “operated under a gen
    eral policy of discrimination.”
    C
    The only corporate policy that the plaintiffs’ evidence
    convincingly establishes is Wal-Mart’s “policy” of allowing
    discretion by local supervisors over employment matters.
    On its face, of course, that is just the opposite of a uniform
    employment practice that would provide the commonality
    needed for a class action; it is a policy against having
    uniform employment practices. It is also a very common
    ——————
    8 Bielby’s conclusions in this case have elicited criticism from the very
    scholars on whose conclusions he relies for his social-framework analy
    sis. See Monahan, Walker, & Mitchell, Contextual Evidence of Gender
    Discrimination: The Ascendance of “Social Frameworks,” 
    94 Va. L. Rev. 1715
    , 1747 (2008) (“[Bielby’s] research into conditions and be
    havior at Wal-Mart did not meet the standards expected of social
    scientific research into stereotyping and discrimination”); 
    id., at 1745, 1747
     (“[A] social framework necessarily contains only general state
    ments about reliable patterns of relations among variables . . . and goes
    no further. . . . Dr. Bielby claimed to present a social framework, but he
    testified about social facts specific to Wal-Mart”); 
    id.,
     at 1747–1748
    (“Dr. Bielby’s report provides no verifiable method for measuring and
    testing any of the variables that were crucial to his conclusions and
    reflects nothing more than Dr. Bielby’s ‘expert judgment’ about how
    general stereotyping research applied to all managers across all of Wal-
    Mart’s stores nationwide for the multi-year class period”).

    Opinion of the Court
    and presumptively reasonable way of doing business—one
    that we have said “should itself raise no inference of dis
    criminatory conduct,” Watson v. Fort Worth Bank & Trust,
    
    487 U. S. 977
    , 990 (1988).
    To be sure, we have recognized that, “in appropriate
    cases,” giving discretion to lower-level supervisors can be
    the basis of Title VII liability under a disparate-impact
    theory—since “an employer’s undisciplined system of
    subjective decisionmaking [can have] precisely the same
    effects as a system pervaded by impermissible intentional
    discrimination.” 
    Id.,
     at 990–991. But the recognition that
    this type of Title VII claim “can” exist does not lead to
    the conclusion that every employee in a company using a
    system of discretion has such a claim in common. To the
    contrary, left to their own devices most managers in any
    corporation—and surely most managers in a corporation
    that forbids sex discrimination—would select sex-neutral,
    performance-based criteria for hiring and promotion that
    produce no actionable disparity at all. Others may choose to
    reward various attributes that produce disparate impact—
    such as scores on general aptitude tests or educational
    achievements, see Griggs v. Duke Power Co., 
    401 U. S. 424
    , 431–432 (1971). And still other managers may be
    guilty of intentional discrimination that produces a sex
    based disparity. In such a company, demonstrating the
    invalidity of one manager’s use of discretion will do noth
    ing to demonstrate the invalidity of another’s. A party
    seeking to certify a nationwide class will be unable to
    show that all the employees’ Title VII claims will in fact
    depend on the answers to common questions.
    Respondents have not identified a common mode of exer
    cising discretion that pervades the entire company—aside
    from their reliance on Dr. Bielby’s social frameworks analy
    sis that we have rejected. In a company of Wal-Mart’s size
    and geographical scope, it is quite unbelievable that all
    managers would exercise their discretion in a common way
    16            WAL-MART STORES, INC. v. DUKES
    Opinion of the Court
    without some common direction. Respondents attempt to
    make that showing by means of statistical and anecdotal
    evidence, but their evidence falls well short.
    The statistical evidence consists primarily of regression
    analyses performed by Dr. Richard Drogin, a statistician,
    and Dr. Marc Bendick, a labor economist. Drogin con
    ducted his analysis region-by-region, comparing the num
    ber of women promoted into management positions with
    the percentage of women in the available pool of hourly
    workers. After considering regional and national data,
    Drogin concluded that “there are statistically significant
    disparities between men and women at Wal-Mart . . .
    [and] these disparities . . . can be explained only by gender
    discrimination.” 603 F. 3d, at 604 (internal quotation
    marks omitted). Bendick compared work-force data from
    Wal-Mart and competitive retailers and concluded that
    Wal-Mart “promotes a lower percentage of women than its
    competitors.” Ibid.
    Even if they are taken at face value, these studies are
    insufficient to establish that respondents’ theory can be
    proved on a classwide basis. In Falcon, we held that one
    named plaintiff ’s experience of discrimination was insuffi
    cient to infer that “discriminatory treatment is typical of
    [the employer’s employment] practices.” 
    457 U. S., at 158
    .
    A similar failure of inference arises here. As Judge Ikuta
    observed in her dissent, “[i]nformation about disparities at
    the regional and national level does not establish the
    existence of disparities at individual stores, let alone raise
    the inference that a company-wide policy of discrimination
    is implemented by discretionary decisions at the store and
    district level.” 603 F. 3d, at 637. A regional pay disparity,
    for example, may be attributable to only a small set of
    Wal-Mart stores, and cannot by itself establish the uni
    form, store-by-store disparity upon which the plaintiffs’
    theory of commonality depends.
    There is another, more fundamental, respect in which
    Cite as: 564 U. S. ____ (2011)           17
    Opinion of the Court
    respondents’ statistical proof fails. Even if it established
    (as it does not) a pay or promotion pattern that differs
    from the nationwide figures or the regional figures in all of
    Wal-Mart’s 3,400 stores, that would still not demonstrate
    that commonality of issue exists. Some managers will
    claim that the availability of women, or qualified women,
    or interested women, in their stores’ area does not mirror
    the national or regional statistics. And almost all of them
    will claim to have been applying some sex-neutral,
    performance-based criteria—whose nature and effects
    will differ from store to store. In the landmark case of
    ours which held that giving discretion to lower-level su
    pervisors can be the basis of Title VII liability under a
    disparate-impact theory, the plurality opinion conditioned
    that holding on the corollary that merely proving that the
    discretionary system has produced a racial or sexual
    disparity is not enough. “[T]he plaintiff must begin by
    identifying the specific employment practice that is chal
    lenged.” Watson, 
    487 U. S., at 994
    ; accord, Wards Cove
    Packing Co. v. Atonio, 
    490 U. S. 642
    , 656 (1989) (approv
    ing that statement), superseded by statute on other
    grounds, 42 U. S. C. §2000e–2(k). That is all the more
    necessary when a class of plaintiffs is sought to be certi
    fied. Other than the bare existence of delegated discre
    tion, respondents have identified no “specific employment
    practice”—much less one that ties all their 1.5 million
    claims together. Merely showing that Wal-Mart’s policy of
    discretion has produced an overall sex-based disparity
    does not suffice.
    Respondents’ anecdotal evidence suffers from the same
    defects, and in addition is too weak to raise any inference
    that all the individual, discretionary personnel decisions
    are discriminatory. In Teamsters v. United States, 
    431 U. S. 324
     (1977), in addition to substantial statistical
    evidence of company-wide discrimination, the Government
    (as plaintiff) produced about 40 specific accounts of racial
    18              WAL-MART STORES, INC. v. DUKES
    Opinion of the Court
    discrimination from particular individuals. See 
    id., at 338
    . That number was significant because the company
    involved had only 6,472 employees, of whom 571 were
    minorities, 
    id., at 337
    , and the class itself consisted of
    around 334 persons, United States v. T.I.M.E.-D. C., Inc.,
    
    517 F. 2d 299
    , 308 (CA5 1975), overruled on other
    grounds, Teamsters, supra. The 40 anecdotes thus repre
    sented roughly one account for every eight members of
    the class. Moreover, the Court of Appeals noted that the
    anecdotes came from individuals “spread throughout” the
    company who “for the most part” worked at the company’s
    operational centers that employed the largest numbers of
    the class members. 
    517 F. 2d, at 315
    , and n. 30. Here, by
    contrast, respondents filed some 120 affidavits reporting
    experiences of discrimination—about 1 for every 12,500
    class members—relating to only some 235 out of Wal-
    Mart’s 3,400 stores. 603 F. 3d, at 634 (Ikuta, J., dissent
    ing). More than half of these reports are concentrated in
    only six States (Alabama, California, Florida, Missouri,
    Texas, and Wisconsin); half of all States have only one or
    two anecdotes; and 14 States have no anecdotes about
    Wal-Mart’s operations at all. Id., at 634–635, and n. 10.
    Even if every single one of these accounts is true, that
    would not demonstrate that the entire company “oper
    ate[s] under a general policy of discrimination,” Falcon,
    
    supra, at 159, n. 15
    , which is what respondents must show
    to certify a companywide class.9
    The dissent misunderstands the nature of the foregoing
    ——————
    9 The dissent says that we have adopted “a rule that a discrimination
    claim, if accompanied by anecdotes, must supply them in numbers
    proportionate to the size of the class.” Post, at 5, n. 4 (GINSBURG, J.,
    concurring in part and dissenting in part). That is not quite accurate.
    A discrimination claimant is free to supply as few anecdotes as he
    wishes. But when the claim is that a company operates under a gen
    eral policy of discrimination, a few anecdotes selected from literally
    millions of employment decisions prove nothing at all.

    analysis. It criticizes our focus on the dissimilarities be
    tween the putative class members on the ground that
    we have “blend[ed]” Rule 23(a)(2)’s commonality require
    ment with Rule 23(b)(3)’s inquiry into whether common
    questions “predominate” over individual ones. See post, at
    8–10 (GINSBURG, J., concurring in part and dissenting in
    part). That is not so. We quite agree that for purposes of
    Rule 23(a)(2) “ ‘[e]ven a single [common] question’ ” will do,
    post, at 10, n. 9 (quoting Nagareda, The Preexistence
    Principle and the Structure of the Class Action, 
    103 Colum. L. Rev. 149
    , 176, n. 110 (2003)). We consider
    dissimilarities not in order to determine (as Rule 23(b)(3)
    requires) whether common questions predominate, but in
    order to determine (as Rule 23(a)(2) requires) whether
    there is “[e]ven a single [common] question.” And there is
    not here. Because respondents provide no convincing
    proof of a companywide discriminatory pay and promotion
    policy, we have concluded that they have not established
    the existence of any common question.10
    In sum, we agree with Chief Judge Kozinski that the
    members of the class:
    “held a multitude of different jobs, at different levels
    of Wal-Mart’s hierarchy, for variable lengths of time,
    in 3,400 stores, sprinkled across 50 states, with a ka
    leidoscope of supervisors (male and female), subject to
    a variety of regional policies that all differed. . . .
    Some thrived while others did poorly. They have little
    in common but their sex and this lawsuit.” 603 F. 3d,
    ——————
    10 For this reason, there is no force to the dissent’s attempt to distin

    questions of law or fact’ between the claims of the lead plaintiff and the
    applicant class ” post, at 9, n. 7 (quoting Falcon, 
    457 U. S., at 162
    (Burger, C. J., concurring in part and dissenting in part)). Here also
    there is nothing to unite all of the plaintiffs’ claims, since (contrary to
    the dissent’s contention, post, at 9, n. 7), the same employment prac
    tices do not “touch and concern all members of the class.”

    III
    We also conclude that respondents’ claims for backpay
    were improperly certified under Federal Rule of Civil
    Procedure 23(b)(2). Our opinion in Ticor Title Ins. Co. v.
    Brown, 
    511 U. S. 117
    , 121 (1994) (per curiam) expressed
    serious doubt about whether claims for monetary relief
    may be certified under that provision. We now hold that
    they may not, at least where (as here) the monetary relief
    is not incidental to the injunctive or declaratory relief.
    A
    Rule 23(b)(2) allows class treatment when “the party
    opposing the class has acted or refused to act on grounds
    that apply generally to the class, so that final injunctive
    relief or corresponding declaratory relief is appropriate
    respecting the class as a whole.” One possible reading of
    this provision is that it applies only to requests for such
    injunctive or declaratory relief and does not authorize the
    class certification of monetary claims at all. We need not
    reach that broader question in this case, because we think
    that, at a minimum, claims for individualized relief (like
    the backpay at issue here) do not satisfy the Rule. The
    key to the (b)(2) class is “the indivisible nature of the
    injunctive or declaratory remedy warranted—the notion
    that the conduct is such that it can be enjoined or declared
    unlawful only as to all of the class members or as to none
    of them.” Nagareda, 84 N. Y. U. L. Rev., at 132. In other
    words, Rule 23(b)(2) applies only when a single injunction
    or declaratory judgment would provide relief to each
    member of the class. It does not authorize class certifica
    tion when each individual class member would be entitled
    to a different injunction or declaratory judgment against
    the defendant. Similarly, it does not authorize class certi
    fication when each class member would be entitled to an
    Cite as: 564 U. S. ____ (2011)                   21
    Opinion of the Court
    individualized award of monetary damages.
    That interpretation accords with the history of the Rule.
    Because Rule 23 “stems from equity practice” that pre
    dated its codification, Amchem Products, Inc. v. Windsor,
    
    521 U. S. 591
    , 613 (1997), in determining its meaning we
    have previously looked to the historical models on which
    the Rule was based, Ortiz v. Fibreboard Corp., 
    527 U. S. 815
    , 841–845 (1999). As we observed in Amchem, “[c]ivil
    rights cases against parties charged with unlawful, class
    based discrimination are prime examples” of what (b)(2) is
    meant to capture. 
    521 U. S., at 614
    . In particular, the
    Rule reflects a series of decisions involving challenges to
    racial segregation—conduct that was remedied by a single
    classwide order. In none of the cases cited by the Advisory
    Committee as examples of (b)(2)’s antecedents did the
    plaintiffs combine any claim for individualized relief with
    their classwide injunction. See Advisory Committee’s
    Note, 39 F. R. D. 69, 102 (1966) (citing cases); e.g., Potts v.
    Flax, 
    313 F. 2d 284
    , 289, n. 5 (CA5 1963); Brunson v.
    Board of Trustees of Univ. of School Dist. No. 1, Clarendon
    Cty., 
    311 F. 2d 107
    , 109 (CA4 1962) (per curiam); Frasier
    v. Board of Trustees of N.C., 
    134 F. Supp. 589
    , 593 (NC
    1955) (three-judge court), aff’d, 
    350 U. S. 979
     (1956).
    Permitting the combination of individualized and class
    wide relief in a (b)(2) class is also inconsistent with the
    structure of Rule 23(b). Classes certified under (b)(1) and
    (b)(2) share the most traditional justifications for class
    treatment—that individual adjudications would be impos
    sible or unworkable, as in a (b)(1) class,11 or that the relief
    ——————
    11 Rule 23(b)(1) applies where separate actions by or against individ
    ual class members would create a risk of “establish[ing] incompatible
    standards of conduct for the party opposing the class,” Rule 23(b)(1)(A),
    such as “where the party is obliged by law to treat the members of the
    class alike,” Amchem Products, Inc. v. Windsor, 
    521 U. S. 591
    , 614
    (1997), or where individual adjudications “as a practical matter, would
    be dispositive of the interests of the other members not parties to the

    Opinion of the Court
    sought must perforce affect the entire class at once, as in a
    (b)(2) class. For that reason these are also mandatory
    classes: The Rule provides no opportunity for (b)(1) or
    (b)(2) class members to opt out, and does not even oblige
    the District Court to afford them notice of the action. Rule
    23(b)(3), by contrast, is an “adventuresome innovation” of
    the 1966 amendments, Amchem, 
    521 U. S., at 614
     (inter
    nal quotation marks omitted), framed for situations “in
    which ‘class-action treatment is not as clearly called for’,”
    
    id., at 615
     (quoting Advisory Committee’s Notes, 28
    U. S. C. App., p. 697 (1994 ed.)). It allows class certifica
    tion in a much wider set of circumstances but with greater
    procedural protections. Its only prerequisites are that “the
    questions of law or fact common to class members pre
    dominate over any questions affecting only individual
    members, and that a class action is superior to other
    available methods for fairly and efficiently adjudicating
    the controversy.” Rule 23(b)(3). And unlike (b)(1) and
    (b)(2) classes, the (b)(3) class is not mandatory; class
    members are entitled to receive “the best notice that is
    practicable under the circumstances” and to withdraw
    from the class at their option. See Rule 23(c)(2)(B).
    Given that structure, we think it clear that individ
    ualized monetary claims belong in Rule 23(b)(3). The
    procedural protections attending the (b)(3) class—
    predominance, superiority, mandatory notice, and the
    right to opt out—are missing from (b)(2) not because the
    Rule considers them unnecessary, but because it considers
    them unnecessary to a (b)(2) class. When a class seeks an
    indivisible injunction benefitting all its members at once,
    there is no reason to undertake a case-specific inquiry into
    ——————
    individual adjudications or would substantially impair or impede their
    ability to protect their interests,” Rule 23(b)(1)(B), such as in “ ‘limited
    fund’ cases, . . . in which numerous persons make claims against a fund
    insufficient to satisfy all claims,” Amchem, 
    supra, at 614
    .
    Cite as: 564 U. S. ____ (2011)           23
    Opinion of the Court
    whether class issues predominate or whether class action
    is a superior method of adjudicating the dispute. Pre
    dominance and superiority are self-evident. But with
    respect to each class member’s individualized claim for
    money, that is not so—which is precisely why (b)(3) re
    quires the judge to make findings about predominance and
    superiority before allowing the class. Similarly, (b)(2) does
    not require that class members be given notice and opt-
    out rights, presumably because it is thought (rightly or
    wrongly) that notice has no purpose when the class is
    mandatory, and that depriving people of their right to sue
    in this manner complies with the Due Process Clause. In
    the context of a class action predominantly for money
    damages we have held that absence of notice and opt-out
    violates due process. See Phillips Petroleum Co. v. Shutts,
    
    472 U. S. 797
    , 812 (1985). While we have never held that
    to be so where the monetary claims do not predominate,
    the serious possibility that it may be so provides an addi
    tional reason not to read Rule 23(b)(2) to include the
    monetary claims here.
    B
    Against that conclusion, respondents argue that their
    claims for backpay were appropriately certified as part of
    a class under Rule 23(b)(2) because those claims do not
    “predominate” over their requests for injunctive and de
    claratory relief. They rely upon the Advisory Committee’s
    statement that Rule 23(b)(2) “does not extend to cases in
    which the appropriate final relief relates exclusively or
    predominantly to money damages.” 39 F. R. D., at 102
    (emphasis added). The negative implication, they argue,
    is that it does extend to cases in which the appropriate
    final relief relates only partially and nonpredominantly to
    money damages. Of course it is the Rule itself, not the
    Advisory Committee’s description of it, that governs. And
    a mere negative inference does not in our view suffice to
    24           WAL-MART STORES, INC. v. DUKES
    Opinion of the Court
    establish a disposition that has no basis in the Rule’s text,
    and that does obvious violence to the Rule’s structural
    features. The mere “predominance” of a proper (b)(2)
    injunctive claim does nothing to justify elimination of Rule
    23(b)(3)’s procedural protections: It neither establishes the
    superiority of class adjudication over individual adjudica
    tion nor cures the notice and opt-out problems. We fail to
    see why the Rule should be read to nullify these protec
    tions whenever a plaintiff class, at its option, combines its
    monetary claims with a request—even a “predominating
    request”—for an injunction.
    Respondents’ predominance test, moreover, creates
    perverse incentives for class representatives to place at
    risk potentially valid claims for monetary relief. In this
    case, for example, the named plaintiffs declined to include
    employees’ claims for compensatory damages in their
    complaint. That strategy of including only backpay claims
    made it more likely that monetary relief would not “pre
    dominate.” But it also created the possibility (if the pre
    dominance test were correct) that individual class mem
    bers’ compensatory-damages claims would be precluded by
    litigation they had no power to hold themselves apart
    from. If it were determined, for example, that a particular
    class member is not entitled to backpay because her denial
    of increased pay or a promotion was not the product of
    discrimination, that employee might be collaterally es
    topped from independently seeking compensatory dam
    ages based on that same denial. That possibility under
    scores the need for plaintiffs with individual monetary
    claims to decide for themselves whether to tie their fates to
    the class representatives’ or go it alone—a choice Rule
    23(b)(2) does not ensure that they have.
    The predominance test would also require the District
    Court to reevaluate the roster of class members continu
    ally. The Ninth Circuit recognized the necessity for this
    when it concluded that those plaintiffs no longer employed
    Cite as: 564 U. S. ____ (2011)           25
    Opinion of the Court
    by Wal-Mart lack standing to seek injunctive or declara
    tory relief against its employment practices. The Court of
    Appeals’ response to that difficulty, however, was not to
    eliminate all former employees from the certified class,
    but to eliminate only those who had left the company’s
    employ by the date the complaint was filed. That solution
    has no logical connection to the problem, since those who
    have left their Wal-Mart jobs since the complaint was filed
    have no more need for prospective relief than those who
    left beforehand. As a consequence, even though the valid
    ity of a (b)(2) class depends on whether “final injunctive
    relief or corresponding declaratory relief is appropriate
    respecting the class as a whole,” Rule 23(b)(2) (emphasis
    added), about half the members of the class approved by
    the Ninth Circuit have no claim for injunctive or declara
    tory relief at all. Of course, the alternative (and logical)
    solution of excising plaintiffs from the class as they leave
    their employment may have struck the Court of Appeals
    as wasteful of the District Court’s time. Which indeed it
    is, since if a backpay action were properly certified for
    class treatment under (b)(3), the ability to litigate a plain
    tiff ’s backpay claim as part of the class would not turn on
    the irrelevant question whether she is still employed at
    Wal-Mart. What follows from this, however, is not that
    some arbitrary limitation on class membership should be
    imposed but that the backpay claims should not be certi
    fied under Rule 23(b)(2) at all.
    Finally, respondents argue that their backpay claims
    are appropriate for a (b)(2) class action because a backpay
    award is equitable in nature. The latter may be true, but
    it is irrelevant. The Rule does not speak of “equitable”
    remedies generally but of injunctions and declaratory
    judgments. As Title VII itself makes pellucidly clear,
    backpay is neither. See 42 U. S. C. §2000e–5(g)(2)(B)(i)
    and (ii) (distinguishing between declaratory and injunc
    tive relief and the payment of “backpay,” see §2000e–
    26             WAL-MART STORES, INC. v. DUKES
    Opinion of the Court
    5(g)(2)(A)).
    C
    In Allison v. Citgo Petroleum Corp., 
    151 F. 3d 402
    , 415
    (CA5 1998), the Fifth Circuit held that a (b)(2) class would
    permit the certification of monetary relief that is “inciden
    tal to requested injunctive or declaratory relief,” which it
    defined as “damages that flow directly from liability to
    the class as a whole on the claims forming the basis of the
    injunctive or declaratory relief.” In that court’s view, such
    “incidental damage should not require additional hearings
    to resolve the disparate merits of each individual’s case; it
    should neither introduce new substantial legal or factual
    issues, nor entail complex individualized determinations.”
    
    Ibid.
     We need not decide in this case whether there are
    any forms of “incidental” monetary relief that are consis
    tent with the interpretation of Rule 23(b)(2) we have
    announced and that comply with the Due Process Clause.
    Respondents do not argue that they can satisfy this stan
    dard, and in any event they cannot.
    Contrary to the Ninth Circuit’s view, Wal-Mart is enti
    tled to individualized determinations of each employee’s
    eligibility for backpay. Title VII includes a detailed reme
    dial scheme. If a plaintiff prevails in showing that an
    employer has discriminated against him in violation of the
    statute, the court “may enjoin the respondent from en
    gaging in such unlawful employment practice, and order
    such affirmative action as may be appropriate, [including]
    reinstatement or hiring of employees, with or without
    backpay . . . or any other equitable relief as the court
    deems appropriate.” §2000e–5(g)(1). But if the employer
    can show that it took an adverse employment action
    against an employee for any reason other than discrimina
    tion, the court cannot order the “hiring, reinstatement, or
    promotion of an individual as an employee, or the payment
    to him of any backpay.” §2000e–5(g)(2)(A).
    Cite as: 564 U. S. ____ (2011)          27
    Opinion of the Court
    We have established a procedure for trying pattern-or
    practice cases that gives effect to these statutory require
    ments. When the plaintiff seeks individual relief such as
    reinstatement or backpay after establishing a pattern or
    practice of discrimination, “a district court must usually
    conduct additional proceedings . . . to determine the scope
    of individual relief.” Teamsters, 431 U. S., at 361. At this
    phase, the burden of proof will shift to the company, but it
    will have the right to raise any individual affirmative
    defenses it may have, and to “demonstrate that the indi
    vidual applicant was denied an employment opportunity
    for lawful reasons.” Id., at 362.
    The Court of Appeals believed that it was possible to
    replace such proceedings with Trial by Formula. A sample
    set of the class members would be selected, as to whom
    liability for sex discrimination and the backpay owing as a
    result would be determined in depositions supervised by a
    master. The percentage of claims determined to be valid
    would then be applied to the entire remaining class, and
    the number of (presumptively) valid claims thus derived
    would be multiplied by the average backpay award in the
    sample set to arrive at the entire class recovery—without
    further individualized proceedings. 603 F. 3d, at 625–627.
    We disapprove that novel project. Because the Rules
    Enabling Act forbids interpreting Rule 23 to “abridge,
    enlarge or modify any substantive right,” 
    28 U. S. C. §2072
    (b); see Ortiz, 
    527 U. S., at 845
    , a class cannot be
    certified on the premise that Wal-Mart will not be entitled
    to litigate its statutory defenses to individual claims. And
    because the necessity of that litigation will prevent back
    pay from being “incidental” to the classwide injunction,
    respondents’ class could not be certified even assuming,
    arguendo, that “incidental” monetary relief can be
    awarded to a 23(b)(2) class.

    _________________

    _________________
    WAL-MART STORES, INC., PETITIONER v.
    BETTY DUKES ET AL.
    ON WRIT OF CERTIORARI TO THE UNITED STATES COURT OF
    APPEALS FOR THE NINTH CIRCUIT
    [June 20, 2011]
    JUSTICE GINSBURG, with whom JUSTICE BREYER,
    JUSTICE SOTOMAYOR, and JUSTICE KAGAN join, concurring
    in part and dissenting in part.
    The class in this case, I agree with the Court, should not
    have been certified under Federal Rule of Civil Procedure
    23(b)(2). The plaintiffs, alleging discrimination in viola
    tion of Title VII, 42 U. S. C. §2000e et seq., seek monetary
    relief that is not merely incidental to any injunctive or
    declaratory relief that might be available. See ante, at 20–
    27. A putative class of this type may be certifiable under
    Rule 23(b)(3), if the plaintiffs show that common class ques-
    tions “predominate” over issues affecting individuals—
    e.g., qualification for, and the amount of, backpay or com
    pensatory damages—and that a class action is “superior”
    to other modes of adjudication.
    Whether the class the plaintiffs describe meets the
    specific requirements of Rule 23(b)(3) is not before the
    Court, and I would reserve that matter for consideration
    and decision on remand.1 The Court, however, disqualifies
    the class at the starting gate, holding that the plaintiffs
    cannot cross the “commonality” line set by Rule 23(a)(2).

    Opinion of GINSBURG, J.
    In so ruling, the Court imports into the Rule 23(a) de
    termination concerns properly addressed in a Rule 23(b)(3)
    assessment.
    I
    A
    Rule 23(a)(2) establishes a preliminary requirement for
    maintaining a class action: “[T]here are questions of law or
    fact common to the class.”2 The Rule “does not require
    that all questions of law or fact raised in the litigation be
    common,” 1 H. Newberg & A. Conte, Newberg on Class
    Actions §3.10, pp. 3–48 to 3–49 (3d ed. 1992); indeed,
    “[e]ven a single question of law or fact common to the
    members of the class will satisfy the commonality re
    quirement,” Nagareda, The Preexistence Principle and the
    Structure of the Class Action, 
    103 Colum. L. Rev. 149
    , 176,
    n. 110 (2003). See Advisory Committee’s 1937 Notes on
    Fed. Rule Civ. Proc. 23, 28 U. S. C. App., p. 138 (citing
    with approval cases in which “there was only a question of
    law or fact common to” the class members).
    A “question” is ordinarily understood to be “[a] subject
    or point open to controversy.” American Heritage Diction
    ary 1483 (3d ed. 1992). See also Black’s Law Dictionary
    1366 (9th ed. 2009) (defining “question of fact” as “[a]
    disputed issue to be resolved . . . [at] trial” and “question of
    law” as “[a]n issue to be decided by the judge”). Thus, a
    “question” “common to the class” must be a dispute, either
    ——————
    2 Rule 23(a) lists three other threshold requirements for class-action
    certification: “(1) the class is so numerous that joinder of all members is
    impracticable”; “(3) the claims or defenses of the representative parties
    are typical of the claims or defenses of the class; and (4) the representa
    tive parties will fairly and adequately protect the interests of the class.”
    The numerosity requirement is clearly met and Wal-Mart does not
    contend otherwise. As the Court does not reach the typicality and
    adequacy requirements, ante, at 9, n. 5, I will not discuss them either,
    but will simply record my agreement with the District Court’s resolu
    tion of those issues.

    of fact or of law, the resolution of which will advance the
    determination of the class members’ claims.3
    B
    The District Court, recognizing that “one significant is
    sue common to the class may be sufficient to warrant cer
    tification,” 222 F. R. D. 137, 145 (ND Cal. 2004), found
    that the plaintiffs easily met that test. Absent an error of
    law or an abuse of discretion, an appellate tribunal has no
    warrant to upset the District Court’s finding of commonal
    ity. See Califano v. Yamasaki, 
    442 U. S. 682
    , 703 (1979)
    (“[M]ost issues arising under Rule 23 . . . [are] committed
    in the first instance to the discretion of the district
    court.”).
    The District Court certified a class of “[a]ll women em
    ployed at any Wal-Mart domestic retail store at any time
    since December 26, 1998.” 222 F. R. D., at 141–143 (in
    ternal quotation marks omitted). The named plaintiffs,
    led by Betty Dukes, propose to litigate, on behalf of the
    class, allegations that Wal-Mart discriminates on the basis
    of gender in pay and promotions. They allege that the
    company “[r]eli[es] on gender stereotypes in making em
    ployment decisions such as . . . promotion[s] [and] pay.”
    App. 55a. Wal-Mart permits those prejudices to infect
    personnel decisions, the plaintiffs contend, by leaving pay
    and promotions in the hands of “a nearly all male manage
    rial workforce” using “arbitrary and subjective criteria.”

     Further alleged barriers to the advancement of
    female employees include the company’s requirement, “as
    a condition of promotion to management jobs, that em

    3 The Court suggests Rule 23(a)(2) must mean more than it says. See
    ante, at 8–10. If the word “questions” were taken literally, the majority
    asserts, plaintiffs could pass the Rule 23(a)(2) bar by “[r]eciting . . .
    questions” like “Do all of us plaintiffs indeed work for Wal-Mart?” Ante,
    at 9. Sensibly read, however, the word “questions” means disputed
    issues, not any utterance crafted in the grammatical form of a question.

    Women fill 70 percent of the hourly jobs in the retailer’s
    stores but make up only “33 percent of management em
    ployees.” 222 F. R. D., at 146. “[T]he higher one looks in
    the organization the lower the percentage of women.” Id.,
    at 155. The plaintiffs’ “largely uncontested descriptive
    statistics” also show that women working in the company’s
    stores “are paid less than men in every region” and “that
    the salary gap widens over time even for men and women
    hired into the same jobs at the same time.” Ibid.; cf.

    550 U. S. 618

    The District Court identified “systems for . . . promoting
    in-store employees” that were “sufficiently similar across
    regions and stores” to conclude that “the manner in which
    these systems affect the class raises issues that are com
    mon to all class members.” 222 F. R. D., at 149. The
    selection of employees for promotion to in-store manage
    ment “is fairly characterized as a ‘tap on the shoulder’
    process,” in which managers have discretion about whose
    shoulders to tap. Id., at 148. Vacancies are not regularly
    posted; from among those employees satisfying minimum
    qualifications, managers choose whom to promote on the
    basis of their own subjective impressions. Ibid.
    Wal-Mart’s compensation policies also operate uniformly
    across stores, the District Court found. The retailer leaves
    open a $2 band for every position’s hourly pay rate. Wal-
    Mart provides no standards or criteria for setting wages
    within that band, and thus does nothing to counter uncon
    scious bias on the part of supervisors. See id., at 146–147.

    Opinion of GINSBURG, J.
    Wal-Mart’s supervisors do not make their discretion
    ary decisions in a vacuum. The District Court reviewed
    means Wal-Mart used to maintain a “carefully constructed
    . . . corporate culture,” such as frequent meetings to re-
    inforce the common way of thinking, regular transfers of
    managers between stores to ensure uniformity through
    out the company, monitoring of stores “on a close and con
    stant basis,” and “Wal-Mart TV,” “broadcas[t] . . . into
    all stores.” Id., at 151–153 (internal quotation marks
    omitted).
    The plaintiffs’ evidence, including class members’ tales
    of their own experiences,4 suggests that gender bias suf
    fused Wal-Mart’s company culture. Among illustrations,
    senior management often refer to female associates as
    “little Janie Qs.” Plaintiffs’ Motion for Class Certification
    in No. 3:01–cv–02252–CRB (ND Cal.), Doc. 99, p. 13 (in
    ternal quotation marks omitted). One manager told an
    employee that “[m]en are here to make a career and
    women aren’t.” 222 F. R. D., at 166 (internal quotation
    marks omitted). A committee of female Wal-Mart execu
    tives concluded that “[s]tereotypes limit the opportunities
    offered to women.” Plaintiffs’ Motion for Class Certifica
    tion in No. 3:01–cv–02252–CRB (ND Cal.), Doc. 99, at 16
    (internal quotation marks omitted).
    Finally, the plaintiffs presented an expert’s appraisal to
    show that the pay and promotions disparities at Wal-Mart
    “can be explained only by gender discrimination and not
    by . . . neutral variables.” 222 F. R. D., at 155. Using
    regression analyses, their expert, Richard Drogin, con

    4 The majority purports to derive from Teamsters v. United States,
    
    431 U. S. 324
     (1977), a rule that a discrimination claim, if accompanied
    by anecdotes, must supply them in numbers proportionate to the size of
    the class. Ante, at 17–18. Teamsters, the Court acknowledges, see
    ante, at 18, n. 9, instructs that statistical evidence alone may suffice,
    431 U. S., at 339; that decision can hardly be said to establish a nu
    merical floor before anecdotal evidence can be taken into account.

    trolled for factors including, inter alia, job performance,
    length of time with the company, and the store where an
    employee worked. Id., at 159.5 The results, the District
    Court found, were sufficient to raise an “inference of dis
    crimination.” Id., at 155–160.
    C
    The District Court’s identification of a common question,
    whether Wal-Mart’s pay and promotions policies gave rise
    to unlawful discrimination, was hardly infirm. The prac
    tice of delegating to supervisors large discretion to make
    personnel decisions, uncontrolled by formal standards, has
    long been known to have the potential to produce dispa
    rate effects. Managers, like all humankind, may be prey
    to biases of which they are unaware.6 The risk of dis
    crimination is heightened when those managers are pre
    dominantly of one sex, and are steeped in a corporate
    culture that perpetuates gender stereotypes.

    5 The Court asserts that Drogin showed only average differences at
    the “regional and national level” between male and female employees.
    Ante, at 16 (internal quotation marks omitted). In fact, his regression
    analyses showed there were disparities within stores. The majority’s
    contention to the contrary reflects only an arcane disagreement about
    statistical method—which the District Court resolved in the plaintiffs’
    favor. 222 F. R. D. 137, 157 (ND Cal. 2004). Appellate review is no
    occasion to disturb a trial court’s handling of factual disputes of this
    order.
    6 An example vividly illustrates how subjective decisionmaking can be
    a vehicle for discrimination. Performing in symphony orchestras was
    long a male preserve. Goldin and Rouse, Orchestrating Impartiality:
    The Impact of “Blind” Auditions on Female Musicians, 90 Am. Econ.
    Rev. 715, 715–716 (2000). In the 1970’s orchestras began hiring musi
    cians through auditions open to all comers. Id., at 716. Reviewers were
    to judge applicants solely on their musical abilities, yet subconscious
    bias led some reviewers to disfavor women. Orchestras that permitted
    reviewers to see the applicants hired far fewer female musicians than
    orchestras that conducted blind auditions, in which candidates played
    behind opaque screens. Id., at 738.

    prototypical cases in this area, Leisner v. New York Tel.
    Co., 
    358 F. Supp. 359
    , 364–365 (SDNY 1973). In deciding
    on promotions, supervisors in that case were to start with
    objective measures; but ultimately, they were to “look at
    the individual as a total individual.” 
    Id., at 365
     (internal
    quotation marks omitted). The final question they were to
    ask and answer: “Is this person going to be successful in
    our business?”

     (internal quotation marks omitted).
    It is hardly surprising that for many managers, the ideal
    candidate was someone with characteristics similar to
    their own.
    We have held that “discretionary employment practices”
    can give rise to Title VII claims, not only when such prac
    tices are motivated by discriminatory intent but also when
    they produce discriminatory results. See Watson v. Fort
    Worth Bank & Trust, 
    487 U. S. 977
    , 988, 991 (1988). But
    see ante, at 17 (“[P]roving that [a] discretionary system
    has produced a . . . disparity is not enough.”). In Watson,
    as here, an employer had given its managers large author
    ity over promotions. An employee sued the bank under
    Title VII, alleging that the “discretionary promotion sys
    tem” caused a discriminatory effect based on race. 
    487 U. S., at 984
     (internal quotation marks omitted). Four
    different supervisors had declined, on separate occasions,
    to promote the employee. 
    Id., at 982
    . Their reasons were
    subjective and unknown. The employer, we noted “had
    not developed precise and formal criteria for evaluating
    candidates”; “[i]t relied instead on the subjective judgment
    of supervisors.” 
    Ibid.
    Aware of “the problem of subconscious stereotypes and
    prejudices,” we held that the employer’s “undisciplined
    system of subjective decisionmaking” was an “employment
    practic[e]” that “may be analyzed under the disparate
    impact approach.” 
    Id.,
     at 990–991. See also Wards Cove
    Packing Co. v. Atonio, 
    490 U. S. 642

    ployment practic[e]” subject to disparate-impact attack).
    The plaintiffs’ allegations state claims of gender dis
    crimination in the form of biased decisionmaking in both
    pay and promotions. The evidence reviewed by the Dis
    trict Court adequately demonstrated that resolving those
    claims would necessitate examination of particular poli
    cies and practices alleged to affect, adversely and globally,
    women employed at Wal-Mart’s stores. Rule 23(a)(2),
    setting a necessary but not a sufficient criterion for class
    action certification, demands nothing further.
    II
    A
    The Court gives no credence to the key dispute common
    to the class: whether Wal-Mart’s discretionary pay and pro
    motion policies are discriminatory. See ante, at 9 (“Re-
    citing” questions like “Is [giving managers discretion over
    pay] an unlawful employment practice?” “is not suffi-
    cient to obtain class certification.”). “What matters,” the
    Court asserts, “is not the raising of common ‘questions,’ ”
    but whether there are “[d]issimilarities within the pro
    posed class” that “have the potential to impede the genera
    tion of common answers.” Ante, at 9–10 (quoting Na
    gareda, Class Certification in the Age of Aggregate Proof,
    84 N. Y. U. L. Rev. 97, 132 (2009); some internal quotation
    marks omitted).
    The Court blends Rule 23(a)(2)’s threshold criterion
    with the more demanding criteria of Rule 23(b)(3), and
    thereby elevates the (a)(2) inquiry so that it is no longer
    “easily satisfied,” 5 J. Moore et al., Moore’s Federal Prac
    tice §23.23[2], p. 23–72 (3d ed. 2011).7 Rule 23(b)(3) certi

    7 The Court places considerable weight on General Telephone Co. of
    Southwest v. Falcon, 
    457 U. S. 147
     (1982). Ante, at 12–13. That case
    has little relevance to the question before the Court today. The lead
    plaintiff in Falcon alleged discrimination evidenced by the company’s
    failure to promote him and other Mexican-American employees and

    Opinion of GINSBURG, J.
    fication requires, in addition to the four 23(a) findings, de
    terminations that “questions of law or fact common to
    class members predominate over any questions affecting
    only individual members” and that “a class action is supe
    rior to other available methods for . . . adjudicating the
    controversy.”8
    The Court’s emphasis on differences between class
    members mimics the Rule 23(b)(3) inquiry into whether
    common questions “predominate” over individual issues.
    And by asking whether the individual differences “impede”
    common adjudication, ante, at 10 (internal quotation
    marks omitted), the Court duplicates 23(b)(3)’s question
    whether “a class action is superior” to other modes of
    adjudication. Indeed, Professor Nagareda, whose “dissimi

    questions of law or fact” between the claims of the lead plaintiff and the
    applicant class. 
    457 U. S., at 162
     (Burger, C. J., concurring in part and
    dissenting in part) (emphasis added). The plaintiff-employee alleged
    that the defendant-employer had discriminated against him intention
    ally. The applicant class claims, by contrast, were “advanced under the
    ‘adverse impact’ theory,” ibid., appropriate for facially neutral prac
    tices. “[T]he only commonality [wa]s that respondent is a Mexican-
    American and he seeks to represent a class of Mexican-Americans.”
    
    Ibid.
     Here the same practices touch and concern all members of the
    class.
    8 “A class action may be maintained if Rule 23(a) is satisfied and if:
    “(1) prosecuting separate actions by or against individual class mem
    bers would create a risk of . . . inconsistent or varying adjudications . . .
    [or] adjudications with respect to individual class members that, as a
    practical matter, would be dispositive of the interests of the other
    members . . . ;
    “(2) the party opposing the class has acted or refused to act on
    grounds that apply generally to the class, so that final injunctive relief
    . . . is appropriate respecting the class as a whole; or
    “(3) the court finds that the questions of law or fact common to class
    members predominate over any questions affecting only individual
    members, and that a class action is superior to other available methods
    for fairly and efficiently adjudicating the controversy.” Fed. Rule Civ.

    larities” inquiry the Court endorses, developed his position
    in the context of Rule 23(b)(3). See 84 N. Y. U. L. Rev.,
    at 131 (Rule 23(b)(3) requires “some decisive degree of
    similarity across the proposed class” because it “speaks
    of common ‘questions’ that ‘predominate’ over individual
    ones”).9 “The Rule 23(b)(3) predominance inquiry” is
    meant to “tes[t] whether proposed classes are sufficiently
    cohesive to warrant adjudication by representation.”
    Amchem Products, Inc. v. Windsor, 
    521 U. S. 591
    , 623
    (1997). If courts must conduct a “dissimilarities” analysis
    at the Rule 23(a)(2) stage, no mission remains for Rule
    23(b)(3).
    Because Rule 23(a) is also a prerequisite for Rule
    23(b)(1) and Rule 23(b)(2) classes, the Court’s “dissimilari
    ties” position is far reaching.       Individual differences
    should not bar a Rule 23(b)(1) or Rule 23(b)(2) class, so
    long as the Rule 23(a) threshold is met. See Amchem
    Products, 
    521 U. S., at 623, n. 19
     (Rule 23(b)(1)(B) “does
    not have a predominance requirement”); Yamasaki, 
    442 U. S., at 701
     (Rule 23(b)(2) action in which the Court noted
    that “[i]t is unlikely that differences in the factual back
    ground of each claim will affect the outcome of the legal
    issue”). For example, in Franks v. Bowman Transp. Co.,
    
    424 U. S. 747
     (1976), a Rule 23(b)(2) class of African-
    American truckdrivers complained that the defendant had
    discriminatorily refused to hire black applicants. We
    recognized that the “qualification[s] and performance” of
    individual class members might vary. 
    Id., at 772
     (internal

    B
    The “dissimilarities” approach leads the Court to train
    its attention on what distinguishes individual class mem
    bers, rather than on what unites them. Given the lack of
    standards for pay and promotions, the majority says,
    “demonstrating the invalidity of one manager’s use of
    discretion will do nothing to demonstrate the invalidity of
    another’s.” Ante, at 15.
    Wal-Mart’s delegation of discretion over pay and promo
    tions is a policy uniform throughout all stores. The very
    nature of discretion is that people will exercise it in vari
    ous ways. A system of delegated discretion, Watson held,
    is a practice actionable under Title VII when it produces
    discriminatory outcomes. 
    487 U. S., at
    990–991; see su
    pra, at 7–8. A finding that Wal-Mart’s pay and promo
    tions practices in fact violate the law would be the first
    step in the usual order of proof for plaintiffs seeking indi
    vidual remedies for company-wide discrimination. Team
    sters v. United States, 
    431 U. S. 324
    , 359 (1977); see Albe
    marle Paper Co. v. Moody, 
    422 U. S. 405
    , 415–423 (1975).
    That each individual employee’s unique circumstances will
    ultimately determine whether she is entitled to backpay or
    damages, §2000e–5(g)(2)(A) (barring backpay if a plaintiff
    “was refused . . . advancement . . . for any reason other
    than discrimination”), should not factor into the Rule
    23(a)(2) determination.
    *    *    *
    The Court errs in importing a “dissimilarities” notion
    suited to Rule 23(b)(3) into the Rule 23(a) commonality
    inquiry. I therefore cannot join Part II of the Court’s
    opinion.
