    SUMMARY **
    Class Certification
    The panel filed an order denying a petition for panel
    rehearing and a petition for rehearing en banc, in a case in
    which the panel reversed the district court’s denial of class
    certification in a putative class action.
    Judge Bea, joined by Judges Bybee, Callahan, Ikuta, and
    Bennett, dissented from the denial of rehearing en banc
    because he would hold that the panel erred in concluding that
    expert opinion testimony need not be admissible evidence in
    order to be considered at the class certification stage. Judge
    Bea wrote that the panel’s decision goes against the court’s
    own binding precedent, the law of four other circuits, and the
    Supreme Court’s clear guidance on the issue.
    ORDER
    The panel has voted to deny the petition for panel
    rehearing.
    The full court was advised of the petition for rehearing
    en banc. A judge requested a vote on whether to rehear the
    matter en banc. The matter failed to receive a majority of
    votes of the nonrecused active judges in favor of en banc
    consideration. Fed. R. App. P. 35.

    SALI V. CORONA REGIONAL MED. CTR.                   3
    The petition for panel rehearing and the petition for
    rehearing en banc are DENIED.
    BEA, Circuit Judge, joined by BYBEE, CALLAHAN,
    IKUTA, and BENNETT, Circuit Judges, dissenting from the
    denial of rehearing en banc:
    I regret that we decided not to rehear this case en banc
    because we could have corrected our own errors. Rather
    than do that, we have established a rule that undermines the
    purpose of the class certification proceeding. We have been
    instructed by the Court that facts necessary to establish the
    elements of a class cannot simply be those that meet a
    pleading standard. 1      But the panel has reduced the
    requirements of class certification below even a pleading
    standard. It has accepted the undisputedly inadmissible
    opinion of plaintiffs’ paralegal—not even that of an attorney
    who is subject to certain pleading standards 2—that the
    plaintiffs have damages typical of the class sought to be
    certified.
    This doesn’t pass the straight-face test.
    It is no surprise the panel’s holding that expert opinion
    testimony need not be admissible at the class certification
    stage is contrary to our own precedent, but also contrary to
    decisions of four other circuits and clear Supreme Court
    guidance.

    I
    This case arises out of a wage and hour class action under
    California law. Sali v. Corona Reg’l Med. Ctr., 
    889 F.3d 623
     (9th Cir. 2018). The two named plaintiffs, Marlyn Sali
    and Deborah Spriggs (“Plaintiffs”), are Registered Nurses
    (“RNs”) who were formerly employed by Corona Regional
    Medical Center (“Corona”). 
    Id. at 627
    . Plaintiffs brought a
    putative class action alleging that, during their employment
    by Corona, they and other nurses were subject to a number
    of policies and practices that violated California’s wage and
    hour laws. 
    Id.
     Based on each of their claims, Plaintiffs
    moved to certify seven classes. 
    Id. at 628
    .
    The district court denied the motion to certify as to all of
    the proposed sub-classes, holding, in relevant part, that Sali
    and Spriggs had failed to satisfy Rule 23(a)’s typicality
    requirement because they failed to submit admissible
    evidence that they had suffered any of the damages suffered
    by the putative class. 
    Id.
     In reaching this decision, the
    district court refused to consider the only piece of evidence
    offered to establish Plaintiffs’ injuries—the declaration of
    Javier Ruiz, a paralegal employed by the law firm
    representing Plaintiffs—because it contained inadmissible
    evidence. 
    Id. at 630
    . The panel explains that the paralegal
    took a “random sampling” of Plaintiffs’ timesheets to
    determine how Corona’s policy of “rounding” clock-in and
    clock-out times to the nearest quarter hour had affected each
    plaintiff’s pay individually. 
    Id.
     Based on this “random
    sampling,” Ruiz concluded that “on average over hundreds
    of shifts, Corona’s rounded time policy undercounted Sali’s
    clock-in and clock-out times by eight minutes per shift and
    Spriggs’s times by six minutes per shift.” 
    Id.
    The district court found the Ruiz declaration was
    inadmissible for three reasons. First, Ruiz lacked personal
    SALI V. CORONA REGIONAL MED. CTR.                           5
    knowledge of the data in the spreadsheets, and thus could not
    authenticate the data. 
    Id. at 630-31
    . Second, Ruiz offered
    opinion testimony, improper unless he qualified as an expert
    witness. 
    Id. at 631
    . Third, Ruiz lacked the qualifications
    necessary for the “cumulative conclusions” he reached via
    “manipulation and analysis of raw data” to be admissible
    under Federal Rule of Evidence 702. 3 
    Id.
     Because the Ruiz
    3
    Notably, the panel’s decision does not question the district court’s
    determination that the Ruiz declaration is deficient under Federal Rule
    of Evidence 702, likely because the conclusion is inescapable. Ruiz
    offered his opinion based on an analysis and interpretation of data—not
    one rationally based on his own perception or personal knowledge—and
    thus he offered an expert opinion, not a lay opinion. See Fed. R. Evid.
    701, 702. The familiar Daubert standard requires courts to assess
    “whether the reasoning or methodology underlying the testimony is
    scientifically valid.” See Daubert v. Merrell Dow Pharm., Inc., 
    509 U.S. 579
    , 592–93 (1993). But here, Ruiz offers no explanation of his
    reasoning or methodology.
    According to his declaration, Ruiz, a paralegal hired by Plaintiffs’
    attorney, compiled Plaintiffs’ clock-in and clock-out times and generated
    spreadsheets which purportedly analyzed how often and to what extent
    Plaintiffs were underpaid by Corona’s allegedly unlawful policies. For
    example, Corona had a policy whereby clock-in and clock-out times
    would be rounded up to fifteen minutes if they were eight or more
    minutes past the quarter-hour mark and rounded down to zero minutes if
    they were seven or fewer minutes past the quarter-hour mark. According
    to the panel opinion, Ruiz used a “random sampling” of the timesheets
    and concluded that, “on average,” the “rounded time policy
    undercounted Sali’s clock-in and clock-out times by eight minutes per
    shift and Spriggs’s times by six minutes per shift.” Sali, 889 F.3d at 630.
    From what evidence the panel deduced Ruiz’s choice of clock-ins and
    clock-outs was “random” escapes me. His declaration says only that he
    “review[ed] and analyze[d] time and payroll records” and “input[ted]
    such information into Excel Spreadsheets in order to determine the
    violation rate and damages.” Not once does he mention “random
    sampling.” Although Ruiz attaches to his declaration spreadsheets
    purporting to show various wage and hour violations, he does not
    describe how he created the spreadsheets, whether the spreadsheets
    6            SALI V. CORONA REGIONAL MED. CTR.
    declaration was inadmissible, the district court did not
    consider it. Left with no other evidence from which to
    conclude Plaintiffs had been injured (much less that their
    injuries were typical of class injuries), the district court
    found that Plaintiffs had failed to satisfy Rule 23(a)’s
    typicality requirement. 4 Plaintiffs challenged this ruling on
    appeal.
    The panel held that the district court’s typicality
    determination was premised on an error of law. Id. at 630.
    Specifically, the panel concluded that, because the class
    represent all or only a portion of the time records, or what methods he
    used to identify alleged violations of the relevant laws and regulations.
    For all we know from his declaration, Ruiz could have “sampled” only
    times that were favorable to his employer’s case and disregarded those
    that were unfavorable. His methodology is simply unexplained.
    In fact, when one sits back and thinks about it, to have a party’s
    paralegal opine on the extent to what the plaintiff was underpaid by
    allowing the paralegal to choose various time-entries without explaining
    his methods is no different than a lawyer interviewing a client and
    choosing only favorable information to include in the client’s pleading.
    And the Supreme Court has repeatedly recognized that Rule 23 requires
    more than a mere pleading standard. See, e.g., Dukes, 
    564 U.S. at 350
    .
    Because the Ruiz declaration is so obviously deficient, it makes
    sense that the panel opinion does not contest the district court’s ruling
    that it would be inadmissible under the Federal Rules of Evidence.
    4
    The district court refused to consider Sali’s and Spriggs’s
    declarations submitted with their reply brief after it struck Ruiz’s
    declaration. Although Plaintiffs’ declarations might have made up for
    the infirmity of Ruiz’s opinion, the district court acted within its
    discretion when it refused to consider their late submissions. See Glenn
    K. Jackson Inc. v. Roe, 
    273 F.3d 1192
    , 1202 (9th Cir. 2001) (“The district
    court had discretion to consider the . . . issue even if it was raised in a
    reply brief.”).
    SALI V. CORONA REGIONAL MED. CTR.                           7
    certification order is “preliminary” and can be entered at an
    early stage of the litigation, but changed later, a motion for
    class certification need not be supported by admissible
    evidence. 5 Id. at 631. Noting that the Supreme Court has
    previously stated that class certification proceedings are “not
    accompanied by the traditional rules and procedure
    applicable to civil trials,” the panel held that the district court
    abused its discretion by limiting its Rule 23 analysis to
    admissible evidence. Id. (citing In re Zurn Pex Plumbing
    Prod. Liab. Litig., 
    644 F.3d 604
    , 613 (8th Cir. 2011)
    (quoting Eisen v. Carlisle & Jacquelin, 
    417 U.S. 156
    , 178
    (1974))). 6 “Inadmissibility alone,” said the panel, “is not a
    5
    The panel attempts to bolster its reasoning for holding that
    evidence need not be admissible at the class certification stage by stating
    that “the evidence needed to prove a class’s case often lies in a
    defendant’s possession and may be obtained only through discovery.”
    Sali, 889 F.3d at 631. Further, “[l]imiting class-certification-stage proof
    to admissible evidence risks terminating actions before a putative class
    may gather crucial admissible evidence.” Id.
    The panel’s reasoning is flawed. First, Plaintiffs here had their wage
    records; the paralegal’s spreadsheet shows the wage information he
    chose from Sali’s and Spriggs’s records. Second, it is well known that
    discovery is not limited to the merits stage of a case. Oppenheimer Fund,
    Inc. v. Sanders, 
    437 U.S. 340
    , 351 (1978). Indeed, “discovery often has
    been used to illuminate issues upon which a district court must pass in
    deciding whether a suit should proceed as a class action under Rule 23.”
    
    Id.
     at 351 n.13.
    6
    To the extent the panel relies on language from the Supreme
    Court’s more than 40-year-old opinion in Eisen, its reliance is misplaced.
    In Eisen, the plaintiff filed a putative class action on behalf of himself
    and all other “odd-lot” traders on the New York Stock Exchange,
    alleging violations of antitrust and securities laws. 
    417 U.S. at 159
    .
    After bouncing back and forth between the district court and the court of
    appeals for over six years on various preliminary issues, the case finally
    made its way to the Supreme Court on, among other issues, whether the
    8            SALI V. CORONA REGIONAL MED. CTR.
    proper basis to reject evidence submitted in support of class
    certification.” Id. at 632. On this basis, the panel reversed
    the district court’s denial of class certification and remanded
    for the district court to reconsider the typicality issue without
    excluding the Ruiz declaration.
    notice requirement of Rule 23 requires the plaintiff to bear the cost of
    notice to members of his class. Id. at 177. In reasoning that it did, the
    Court held that the district court was wrong to reach its contrary
    conclusion by making a preliminary determination on the merits of the
    case: that defendants were “more than likely” to lose. Id. Such a
    determination, the Court held, could result in “substantial prejudice to a
    defendant” because the proceedings involved at the class certification
    stage are not governed by “the traditional rules and procedures
    applicable to civil trials.” Id. at 178.
    It is this language that the Zurn Pex court and the panel here deploy
    for the proposition that class certification proceedings are “preliminary”
    and thus do not require admissible evidence. 
    644 F.3d at
    613–14. Both
    misread the language. First, Eisen did not involve the issue here: whether
    a plaintiff must proffer admissible evidence of damages typical of those
    claimed for the putative class(es) for a court to grant class certification.
    As noted, Eisen involved the issue of who bore the cost of giving notice.
    In Dukes, the Supreme Court made it very clear that the passage cited by
    the Zurn Pex court and the panel dealt not with the propriety of class
    certification (as the class had already been certified), but instead only
    with shifting the cost of Rule 23(c)(2) notice from plaintiff to defendants.
    
    564 U.S. at
    351 n.6. And the Court went on: “To the extent the quoted
    statement goes beyond the permissibility of a merits inquiry for any other
    pretrial purpose [beside the cost of notice issue], it is the purest dictum
    and is contradicted by our other cases.” 
    Id.
     Thus, Eisen is inapplicable
    to Rule 23 class certification determinations, and we should follow the
    more recent applicable cases, Dukes and Comcast Corporation v.
    Behrend, 
    569 U.S. 27
     (2013), which are clearly at odds with the panel’s
    decision.
    SALI V. CORONA REGIONAL MED. CTR.                           9
    II
    The class certification stage cannot be disdained as the
    panel has done here. We have held a district court’s
    determination on class certification often “sounds the death
    knell of the litigation,” whether by dismissal, if class
    certification is denied, or by settlement, if class certification
    is granted. Chamberlan v. Ford Motor Co., 
    402 F.3d 952
    ,
    957 (9th Cir. 2005) (quoting Blair v. Equifax Check Servs.,
    Inc., 
    181 F.3d 832
    , 834 (7th Cir. 1999)). It is for this reason
    that federal courts in the past—including the U.S. Supreme
    Court—have treated the class certification stage not as a
    “preliminary” step in the litigation, but as an oftentimes
    dispositive step demanding a more stringent evidentiary
    standard.
    Besides the fact that the panel’s decision is contrary to
    our own precedent, 7 I take issue with the panel’s decision for
    7
    Although the panel opinion cites Ellis v. Costco Wholesale Corp.,
    
    657 F.3d 970
     (9th Cir. 2011), as if it were to lend support to the panel’s
    holding, quite the contrary is the case. In Costco, we reversed a district
    court’s grant of class certification to a group of female employees who
    alleged that Costco Wholesale Corporation (“Costco”) had discriminated
    against them on the basis of gender. 
    Id. at 974
    . After first finding that
    the plaintiffs’ expert report would be admissible under Daubert, the
    district court refused to engage in any analysis of the validity or
    persuasiveness of the expert report and, instead, held that the mere fact
    that the opinion was admissible was sufficient to support class
    certification. 
    Id. at 982
    . We held that, although the district court had
    “correctly applied the evidentiary standard set forth in Daubert,” it
    abused its discretion by certifying a class based only on the admissibility
    of the expert report, without consideration of the report’s persuasiveness.
    
    Id.
     In other words, we said that admissibility of the proffered evidence
    is not sufficient to demonstrate that such evidence provided the proof
    required under Rule 23. Rather, admissibility is a threshold issue to
    determine before considering the evidence’s persuasiveness.
    10           SALI V. CORONA REGIONAL MED. CTR.
    two important reasons. First, it puts our court on the wrong
    side of a lopsided circuit split. And second, it defies clear
    Supreme Court guidance on this issue.
    A. Four of five other circuits to consider this issue
    disagree with the panel.
    The panel’s opinion also puts us on the short side of a
    lopsided circuit split—the Second, Third, Fifth, and Seventh
    The panel selectively quotes Costco to support a contrary ruling.
    First, it totally omits Costco’s holding that the district court was correct
    to apply Daubert, and thus correct to consider admissibility at the first
    step of the Rule 23 analysis. See Sali, 889 F.3d at 631–32 (failing to
    mention Costco’s holding that the district court had “correctly applied”
    Daubert). Next, the panel cites Costco’s holding that a district court
    abuses its discretion when it limits its Rule 23 analysis “to a
    determination of whether Plaintiffs’ evidence on the point was
    admissible” (where the evidence was admissible). Id. at 631 (quoting
    Costco, 
    657 F.3d at 982
    ). Ignoring Costco’s contrary language, the panel
    deprecates what the Costco court stated as to the importance of
    admissibility in evaluating compliance with Rule 23: “[A] district court
    should evaluate admissibility,” the panel says, “[b]ut admissibility must
    not be dispositive.” Id. at 634 (emphasis added).
    The panel’s interpretation of Costco distorts its basic holding. To
    the extent Costco held that admissibility is not sufficient to demonstrate
    a plaintiff’s compliance with Rule 23, the panel is correct: mere
    admissibility does not establish compliance. Costco thus stands for the
    proposition that class certification cannot be granted on the basis of
    admissibility alone.
    But the panel takes that holding a step further by concluding that
    neither is admissibility necessary. Costco did not say that. Costco
    supports the opposite conclusion that evidence must be admissible for it
    to be considered at the class certification stage. Far from supporting the
    panel’s opinion, Costco is inconsistent with it. But rather than rehearing
    this case en banc to correct the conflict, we have left district courts and
    litigants in an impossible position.
    SALI V. CORONA REGIONAL MED. CTR.                  11
    Circuits all require expert testimony to be admissible to be
    considered at the class certification stage. See In re Blood
    Reagents Antitrust Litig., 
    783 F.3d 183
    , 187 (3d Cir. 2015)
    (“We join certain of our sister courts to hold that a plaintiff
    cannot rely on challenged expert testimony, when critical to
    class certification, to demonstrate conformity with Rule 23
    unless the plaintiff also demonstrates, and the trial court
    finds, that the expert testimony satisfies the standard set out
    in Daubert.”); In re U.S. Foodservice Inc. Pricing Litig.,
    
    729 F.3d 108
    , 129 (2d Cir. 2013) (holding that the district
    court properly “considered the admissibility of the expert
    testimony” at the class certification stage, but declining to
    decide exactly “when a Daubert analysis forms a necessary
    component of a district court’s rigorous analysis”) (emphasis
    added); Am. Honda Motor Co. v. Allen, 
    600 F.3d 813
    , 817
    (7th Cir. 2010) (vacating the district court’s class
    certification order because it “fail[ed] to [resolve clearly] the
    issue of . . . admissibility before certifying the class” and the
    expert testimony in question failed to satisfy Daubert);
    Unger v. Amedisys Inc., 
    401 F.3d 316
    , 319 (5th Cir. 2005)
    (holding that “findings [at the class certification stage] must
    be made based on adequate admissible evidence to justify
    class certification”). Two other circuits have so held in
    unpublished rulings. See In re Carpenter Co., No. 14-0302,
    
    2014 WL 12809636
    , at *3 (6th Cir. Sept. 29, 2014) (holding
    that, in light of Comcast and Dukes, the district court
    properly applied Daubert at the class certification stage);
    Sher v. Raytheon Co., 419 F. App’x 887, 890 (11th Cir.
    2011) (holding that “the district court erred as a matter of
    law” by failing to conduct a Daubert analysis at the class
    certification stage).
    The panel acknowledges its conflict with the Third,
    Fifth, and Seventh Circuits, but emphasizes its agreement
    with the Eighth—the only circuit to come out the other way.
    12         SALI V. CORONA REGIONAL MED. CTR.
    Sali, 889 F.3d at 632 (citing Zurn Pex, 
    644 F.3d at
    612–13).
    But even that case does not fully support the panel’s
    decision. In Zurn Pex, homeowners brought a class action
    against a plumbing company, claiming that the systems
    installed by the company were defective. 
    644 F.3d at 608
    .
    At the class certification stage, the plaintiffs proffered
    evidence from two experts regarding the failure of the
    plumbing systems. 
    Id. at 609
    . The defendant attempted to
    exclude the testimony under Daubert, and the plaintiffs
    argued Daubert did not apply. 
    Id. at 610
    . The district court
    conducted a “focused” Daubert analysis, declining to rule on
    whether the testimony was admissible, but also taking the
    Daubert factors into consideration in determining whether
    the expert testimony supported class certification. 
    Id.
     at
    610–11. The district court found that the expert testimony
    supported class certification and certified the class. 
    Id.
     The
    Eighth Circuit affirmed, holding that the district court’s
    “focused” Daubert analysis was correct and stating that
    expert testimony need not be admissible at the class
    certification stage, although the Daubert factors should be
    considered. 
    Id. at 613
    .
    Zurn Pex is consistent with the panel’s position that
    inadmissible expert testimony can be used to support a class
    certification motion, though as noted above, the Zurn Pex
    court, like the panel here, misreads Eisen. But Zurn Pex’s
    requirement that district courts undertake a “focused”
    Daubert analysis is more specific and rigorous than the
    panel’s analysis and holding was here. The panel states that
    the district court “may” consider admissibility and “should”
    evaluate evidence in light of Daubert, but provides no
    further guidance as to what standard district courts should
    apply.
    SALI V. CORONA REGIONAL MED. CTR.                13
    Overall, the great weight of persuasive authority
    counsels against the panel’s decision. In total, six circuits
    have held in published or unpublished decisions that expert
    testimony must be admissible to be considered at the class
    certification stage. Before the panel’s decision in this case,
    only one circuit had reached the opposite conclusion—and
    even that circuit created a more stringent evidentiary
    standard than the one applied by the panel here.
    B. The Supreme Court’s precedent counsels against the
    panel’s holding.
    It is no wonder the overwhelming majority of circuits to
    address this question have come down on the side opposite
    the panel. Although the Supreme Court has not directly
    addressed whether expert testimony must be admissible to
    be considered on a motion for class certification, its guidance
    in this area heavily favors the circuit majority rule. Indeed,
    the last time our court issued an opinion loosening the
    requirements for class certification, the Court reversed us
    and offered guidance that we would have been wise to heed
    here.
    In Wal-Mart Stores, Inc. v. Dukes, 
    564 U.S. 338
    , 342
    (2011), the Supreme Court reversed an en banc panel of this
    court that had approved an order certifying an expansive,
    1.5-million-person class. The class comprised “current and
    former female employees of petitioner Wal-Mart who
    allege[d] that the discretion exercised by their local
    supervisors over pay and promotion matters violate[d] Title
    VII by discriminating against women.” 
    Id.
     Before
    analyzing whether the plaintiffs had satisfied the various
    elements of Rule 23, the Court discussed in some detail the
    evidentiary standard appropriate at the class certification
    stage. 
    Id.
     at 350–51. The Court noted that “Rule 23 does
    not set forth a mere pleading standard”; rather, the moving
    14         SALI V. CORONA REGIONAL MED. CTR.
    party must “affirmatively demonstrate his compliance with
    the Rule.” 
    Id. at 350
     (emphasis added). The plaintiff “must
    be prepared to prove that there are in fact sufficiently
    numerous parties, common questions of law or fact, etc.” 
    Id.
    (first emphasis added). The Court thus reemphasized the
    point, made in a previous case, that the district court must
    engage in a “rigorous analysis” to determine whether Rule
    23 has been satisfied. 
    Id. at 351
     (quoting Falcon, 457 U.S.
    at 161). And, relevant here, the Court expressly “doubt[ed]”
    the idea, advanced by the district court in Dukes and adopted
    by the panel here, that “Daubert [does] not apply to expert
    testimony at the certification stage of class-action
    proceedings.” Id. at 354.
    At least one other Supreme Court case counsels against
    the panel’s holding here. In Comcast Corporation v.
    Behrend, 
    569 U.S. 27
     (2013), the Supreme Court discussed
    again the evidentiary standard at the class certification stage
    when it reversed the Third Circuit’s opinion affirming a
    grant of class certification. The Court reaffirmed the
    principles emphasized in Dukes that Rule 23 demands more
    than a “mere pleading standard” and that a plaintiff must
    “affirmatively demonstrate”—that is, “prove”—that he “in
    fact” has complied with Rule 23. Comcast, 
    569 U.S. at
    33
    (citing Dukes, 
    564 U.S. at
    350–51) (emphasis in original).
    Although it failed to address directly whether evidence must
    be admissible at the class certification stage, the Court held
    that “satisfy[ing] through evidentiary proof at least one of
    the provisions of Rule 23(b)” is a prerequisite to class
    certification. 
    Id.
     (emphasis added). Once again, the Court’s
    guidance strongly suggests that it favors the rule of the
    majority of circuits, which the panel in this case rejected.
    SALI V. CORONA REGIONAL MED. CTR.               15
    III
    The panel’s decision in this case involves a question of
    exceptional importance and is plainly wrong. It goes against
    our own binding precedent, the law of four other circuits, and
    the Supreme Court’s clear guidance on this issue. Our court
    should have reheard this case en banc to reverse the panel’s
    decision on our own.
