    SUMMARY **
    Civil Rights
    The panel amended its opinion filed on September 28,
    2021, filed an amended opinion, denied a petition for panel
    rehearing, denied a petition for rehearing en banc on behalf
    of the court, and ordered that no further petitions shall be
    entertained.
    In the amended opinion, the panel affirmed the district
    court’s order denying, on summary judgment, qualified
    immunity to Police Chief James McElvain on plaintiff’s
    First Amendment and Equal Protection disparate treatment
    claim; and remanded for the district court to clarify its ruling
    on the question of whether McElvain was entitled to
    qualified immunity on plaintiff’s claim that she was
    retaliated against, in violation of the Fourteenth
    Amendment’s Equal Protection Clause, in an action brought
    pursuant to 
    42 U.S.C. § 1983
     alleging retaliation and
    employment discrimination.

    This summary constitutes no part of the opinion of the court. It
    has been prepared by court staff for the convenience of the reader.
    BALLOU V. MCELVAIN                        3
    Plaintiff, Julie Ballou, asserted that McElvain
    discriminated against her because of her gender by
    intentionally subjecting her to internal affairs investigations
    to preclude her eligibility for promotion and then declining
    to promote her to sergeant even though she was the most
    qualified candidate. The panel held that, construing all facts
    and inferences in her favor, Ballou sufficiently alleged
    unconstitutional sex discrimination in violation of the Equal
    Protection Clause of the Fourteenth Amendment. Plaintiff
    established a prima facie claim for disparate treatment and
    the record supported the conclusion that McElvain’s
    articulated reasons for not promoting Ballou were
    pretextual. The panel rejected, as profoundly mistaken,
    McElvain’s argument that to state an equal protection claim,
    proof of discriminatory animus alone was insufficient, and
    plaintiff must show that defendants treated plaintiff
    differently from other similarly situated individuals. The
    panel stated that the existence of a comparator is not a
    prerequisite to stating a disparate treatment claim under the
    Fourteenth Amendment.
    The panel held that the actions alleged here were so
    closely analogous to those identified in Lindsey v. Shalmy,
    
    29 F.3d 1382
    , 1385-86 (9th Cir. 1994), and so clearly
    covered by the focus on promotion in Bator v. State of
    Hawai‘i, 
    39 F.3d 1021
    , 1028 (9th Cir. 1994), that any
    reasonable officer would recognize that discriminatorily
    conducting an investigation to stall a promotion as
    unconstitutional under the two cases, read in
    combination. McElvain was therefore not entitled to
    qualified immunity on the claim that he encouraged and
    sustained discriminatory investigations into Ballou’s
    workplace performance and thereby denied her promotion at
    least in part on the basis of sex. As Ballou’s disparate
    treatment claim alleged that McElvain violated her clearly
    4                  BALLOU V. MCELVAIN
    established rights under the Equal Protection Clause,
    McElvain was not entitled to qualified immunity on that
    claim.
    The panel next addressed the question of whether
    McElvain was entitled to qualified immunity on the claim
    that he violated Ballou’s rights under the Equal Protection
    Clause of the Fourteenth Amendment by retaliating against
    her for opposing defendants’ sex discrimination. Because
    the panel’s jurisdiction under the collateral order doctrine
    was limited to reviewing the denial of qualified immunity,
    and because the panel could not discern from the district
    court’s order whether it granted, denied, or did not address
    McElvain’s assertion of qualified immunity as to Ballou’s
    Fourteenth Amendment Equal Protection retaliation claim,
    the panel remanded to the district court to clarify its order as
    to that claim.
    Finally, the panel affirmed the denial of qualified
    immunity to McElvain on Ballou’s First Amendment
    retaliation claim. The panel held that Ballou’s speech
    opposing sex discrimination in the workplace was inherently
    speech on a matter of public concern and was clearly
    protected by the First Amendment. Whether Ballou’s
    protected expression actually was the but-for cause of the
    adverse employment actions went to the ultimate question of
    liability and needed to be resolved by the jury at trial. But it
    did not bear on the question before the panel now—whether
    retaliating against Ballou for that expression would, as a
    matter of law, violate her clearly established constitutional
    rights. Because Ballou’s factual account was not “blatantly
    contradicted by the record,” the panel would not disturb the
    district court’s determination that Ballou’s retaliation claims
    were sufficiently supported to survive summary judgment.

    With the opinion as amended, the panel unanimously
    voted to deny the petition for panel rehearing. Chief Judge
    Murguia voted to deny the petition for rehearing en banc,
    and Judge Boggs and Judge Berzon so recommended. The
    full court has been advised of the petition for rehearing en
    banc, and no judge has requested a vote on whether to rehear
    the matter en banc. Fed. R. App. P. 35. The petition for
    panel rehearing and rehearing en banc, Docket No. 42, is
    DENIED. No further petitions for panel rehearing or
    rehearing en banc will be entertained.
    6                  BALLOU V. MCELVAIN
    OPINION
    BERZON, Circuit Judge:
    Julie Ballou, a police officer in Vancouver, Washington,
    scored high enough on the examination for promotion to
    sergeant to be eligible for promotion but was repeatedly
    passed over, including when she was highest on the
    promotion list. James McElvain, the Police Chief who made
    the promotion decisions, instigated a series of investigations
    into Ballou’s reporting practices and refused to promote her
    while the investigations were pending. Ballou sued, alleging
    that McElvain violated the First Amendment and the Equal
    Protection Clause of the Fourteenth Amendment by
    discriminating against her on the basis of sex in refusing to
    promote her and by retaliating against her for objecting to
    that discrimination.
    We affirm the denial of qualified immunity as to
    Ballou’s First Amendment and Equal Protection Clause
    disparate treatment claims. As to McElvain’s argument that
    he is entitled to qualified immunity on Ballou’s claim that
    she was retaliated against in violation of the Equal Protection
    Clause of the Fourteenth Amendment, we cannot discern
    from the district court’s order whether we have jurisdiction
    under the collateral order doctrine to resolve that question,
    and so we remand to the district court to clarify its ruling.
    I.
    In 2017, Julie Ballou and several other Vancouver police
    officers took an exam to determine eligibility for promotion
    to the rank of sergeant. Under Washington civil service
    rules, when a vacancy arises, the Police Chief has discretion
    to promote any of the three highest-scoring candidates on the
    relevant promotion exam. Rules & Regs., Vancouver Civ.
    BALLOU V. MCELVAIN                         7
    Serv. Comm’n § 11.3(a) (2020). Between 2013 and 2018,
    every time he filled a vacancy McElvain promoted the
    highest-ranked person on the relevant list.
    Ballou scored third-highest in her sitting of the
    sergeant’s exam. At the time, there were no sergeant
    vacancies available, so no one was promoted.
    Three months after the sergeant’s exam, before any
    promotions had been made, a citizen called the Vancouver
    police department to follow up on a burglary report she had
    made to Ballou. Considering the inquiry, Rod Trumpf, the
    supervising sergeant, discovered that, in violation of
    department policy, Ballou had not written and filed a report
    on the incident. Trumpf thereupon initiated an internal
    affairs investigation into Ballou’s conduct.
    The following month, Chief McElvain asked Barbara
    Kipp, an investigating officer, to determine if Ballou’s
    failure to file a report “was a one-time incident or [part] of a
    pattern.” Kipp reviewed over a year of records and identified
    seven incidents for which, in Kipp’s view, Ballou should
    have filed a report but did not. In June of 2018, Ballou’s
    supervising lieutenant issued her a letter of reprimand.
    Two sergeant vacancies arose while the internal affairs
    investigation of Ballou was ongoing. McElvain promoted
    the two officers ranked higher than Ballou on the eligibility
    list, leaving Ballou the highest-ranked officer on the sergeant
    list. Shortly after Ballou received her letter of reprimand,
    McElvain, citing the internal affairs investigations and
    Ballou’s failure to follow protocol, announced that he did not
    intend to promote her to sergeant.
    This decision caused a stir in the department. The week
    following McElvain’s announcement, some women
    8                   BALLOU V. MCELVAIN
    officers—but not Ballou herself—raised at a meeting with
    McElvain Ballou’s eligibility for promotion. In that
    meeting, officers indicated that it was atypical to initiate a
    broad internal affairs investigation into an officer for failing
    to follow up on a citizen call. One of the officers in that
    meeting, Commander Amy Foster, pointed out that Brian
    Ruder, an officer who had received a verbal reprimand for
    failing to write a report on a sexual assault call, had not, at
    that time, been subjected to an internal affairs investigation,
    either into the specific incident or into his reporting practices
    generally.
    The day after that meeting, McElvain announced that he
    would be promoting Erik Jennings, the person ranked
    directly below Ballou on the sergeant list. McElvain also
    directed that an investigation be opened against Ruder who,
    after Jennings’s promotion, was tied with Kevin Barton as
    the next-highest-ranked candidate after Ballou.
    Shortly thereafter, Ballou sent McElvain and Eric
    Holmes, the Vancouver city manager, an email stating that
    McElvain’s decision to pass her over for promotion was “a
    textbook example of applying a different, and harsher,
    standard to women than to men.” In her email, Ballou
    asserted that McElvain had “in more than one instance . . .
    promoted male candidates who have had sustained [internal
    affairs investigation] findings against them for much more
    serious violations.” This assertion apparently referred to
    Ryan Junker and Jeremy Free, officers who had previously
    been promoted to the rank of corporal despite having been
    disciplined following internal affairs investigations—in
    Junker’s case, for shooting himself in the foot, and in Free’s
    case, for obstructing an investigation into an allegation that
    he had driven under the influence of alcohol.
    BALLOU V. MCELVAIN                        9
    Ballou’s email contended that she had been “the victim
    of gender discrimination at least twice: first by the sergeant
    who filed the [internal] complaint against me but not the men
    on his shift for the same conduct, and second by the Chief
    who chose not to promote me because of a minor policy
    violation but who, on at least several occasions, promoted
    men with more serious [disciplinary] findings.” She further
    stated: “I have been advised to hire a lawyer and file a gender
    discrimination suit against the City. I would prefer not to do
    that for many reasons, not only because of the cost to the
    City, but more importantly, because of the harm it will cause
    to the City’s reputation.” She concluded by asking that she
    be promoted immediately. Ballou followed up this email
    with a list of possible report-writing violations by male
    officers.
    Following Ballou’s email, McElvain neither promoted
    Ballou nor investigated any of the violations by the other
    officers she had identified. Ballou continued to be
    investigated for violations of department reporting policy.
    Between February 2018, when she first became eligible for
    promotion to sergeant, and May 2019, when she was
    ultimately promoted, Ballou was the subject of eight internal
    affairs investigations.
    In September 2018, two months after her email to
    McElvain but more than seven months before her eventual
    promotion, Ballou served a state tort claim on the City,
    alleging sex discrimination and seeking damages. Shortly
    thereafter, a new sergeant vacancy became available.
    McElvain promoted Kevin Barton, a candidate ranked just
    below Ballou on the eligibility list and tied with Ruder.
    After that promotion, in November 2018, Ballou filed a
    second state tort claim, alleging “further sexual
    discrimination due to her most recent non-promotion,”
    10                 BALLOU V. MCELVAIN
    “further claims for discriminatory discipline,” and “claims
    for retaliation.”
    Ballou filed the present suit under 
    42 U.S.C. § 1983
     in
    federal court on January 3, 2019, alleging denial of her
    constitutional right to equal protection and seeking damages.
    The following week, on January 10, McElvain announced
    that he intended to promote Ruder, now the second-ranked
    candidate, over Ballou.         McElvain contends that he
    announced this decision before he learned of this lawsuit.
    In May 2019, more than a year after she first became
    eligible for promotion, McElvain promoted Ballou to the
    rank of sergeant.
    After Ruder’s promotion, Ballou amended her federal
    complaint to add that the ongoing investigations against her
    and the decision to promote Ruder had been retaliatory, in
    violation of Ballou’s rights under the Petition Clause of the
    First Amendment. She also filed a charge with the Equal
    Employment Opportunity Commission (EEOC) against the
    City of Vancouver and then brought new claims against the
    City under Title VII of the Civil Rights Act, 42 U.S.C.
    § 2000e.     The amended complaint retained Ballou’s
    assertion that McElvain had violated her right to be free from
    sex discrimination under the Equal Protection Clause by
    discriminatorily investigating her, passing her over for
    promotion, and “retaliating against her for opposing . . . sex
    discrimination.”
    McElvain filed a motion for partial judgment on the
    pleadings, asserting qualified immunity as to Ballou’s
    claims of disparate treatment and of retaliation. The district
    court denied that motion in its entirety. Both McElvain and
    the City of Vancouver then moved for summary judgment,
    with McElvain again asserting qualified immunity. The
    BALLOU V. MCELVAIN                       11
    district court denied summary judgment on Ballou’s Equal
    Protection and First Amendment claims and denied
    McElvain qualified immunity on the ground that “the Equal
    Protection Clause prohibits discrimination, and . . . the First
    Amendment prohibits retaliation.” The district court also
    denied the City’s motion for summary judgment on several
    of Ballou’s Title VII and state-law claims but granted
    summary judgment on her hostile-work-environment claim.
    McElvain moved for reconsideration, which the district
    court denied.
    McElvain now appeals the denial of qualified immunity.
    II.
    This case comes before us as an interlocutory appeal
    from a denial of summary judgment. Denials of summary
    judgment are typically not appealable, as they are not final
    orders. Isayeva v. Sacramento Sheriff’s Dep’t, 
    872 F.3d 938
    ,
    944 (9th Cir. 2017). We may, however, review orders
    denying qualified immunity under the collateral order
    exception to finality. Plumhoff v. Rickard, 
    572 U.S. 765
    ,
    771–73 (2014); Foster v. City of Indio, 
    908 F.3d 1204
    , 1209
    (9th Cir. 2018) (per curiam). In such cases, the scope of our
    review is “circumscribed.” Foster, 908 F.3d at 1210
    (quoting George v. Morris, 
    736 F.3d 829
    , 834 (9th Cir.
    2013)). Unless the plaintiff’s version of events is “blatantly
    contradicted by the record, so that no reasonable jury could
    believe it,” Orn v. City of Tacoma, 
    949 F.3d 1167
    , 1171 (9th
    Cir. 2020) (quoting Scott v. Harris, 
    550 U.S. 372
    , 380
    (2007)), we may not review the district court’s determination
    that “the pretrial record was sufficient to show a genuine
    issue of fact for trial,” Foster, 908 F.3d at 1210 (quoting
    Johnson v. Jones, 
    515 U.S. 304
    , 307 (1995)). We therefore
    lack jurisdiction over any aspects of the present dispute that
    turn on that question and instead consider only “whether the
    12                 BALLOU V. MCELVAIN
    defendant would be entitled to qualified immunity as a
    matter of law, assuming all factual disputes are resolved, and
    all reasonable inferences are drawn, in plaintiff’s favor.”
    Estate of Anderson v. Marsh, 
    985 F.3d 726
    , 731 (9th Cir.
    2021) (alterations omitted) (quoting George, 736 F.3d
    at 836); see id. at 732.
    We review the denial of qualified immunity de novo.
    Rice v. Morehouse, 
    989 F.3d 1112
    , 1120 (9th Cir. 2021). We
    must affirm the district court’s denial of qualified immunity
    if, resolving all factual disputes and drawing all inferences
    in Ballou’s favor, McElvain’s conduct (1) violated a
    constitutional right that (2) was clearly established at the
    time of the violation. See Estate of Anderson, 985 F.3d
    at 731; see also Ashcroft v. al-Kidd, 
    563 U.S. 731
    , 735
    (2011). Conduct violates a “clearly established” right if “the
    unlawfulness of the action in question [is] apparent in light
    of some pre-existing law.” Benavidez v. Cnty. of San Diego,
    
    993 F.3d 1134
    , 1151–52 (9th Cir. 2021) (quoting Devereaux
    v. Perez, 
    218 F.3d 1045
    , 1053 (9th Cir. 2000)). For a right
    to be “clearly established,” there need not be a Supreme
    Court or circuit case “directly on point,” but “existing
    precedent must place the lawfulness of the conduct beyond
    debate.” Tobias v. Arteaga, 
    996 F.3d 571
    , 580 (9th Cir.
    2021) (alteration and internal quotation marks omitted)
    (quoting District of Columbia v. Wesby, 
    138 S. Ct. 577
    , 590
    (2018)).
    A. Disparate Treatment
    We first consider whether McElvain is entitled to
    qualified immunity on Ballou’s claim that she was subjected
    to discriminatory treatment because of her sex, in violation
    of the Equal Protection Clause of the Fourteenth
    Amendment. Ballou contends that McElvain discriminated
    against her because of her gender by intentionally subjecting
    BALLOU V. MCELVAIN                      13
    her to internal affairs investigations to preclude her
    eligibility for promotion and then declining to promote her
    to sergeant even though she was the most qualified
    candidate.
    i.
    The district court held that Ballou had produced
    sufficient evidence, including circumstantial evidence of
    discriminatory intent, to preclude summary judgment on the
    first qualified immunity prong, whether McElvain failed to
    promote her because of sex. We agree that, construing all
    facts and inferences in her favor, Ballou has sufficiently
    alleged unconstitutional sex discrimination.
    The central inquiry in an Equal Protection Clause claim
    is whether a government action was motivated by a
    discriminatory purpose. See Ave. 6E Invs., LLC v. City of
    Yuma, 
    818 F.3d 493
    , 504 (9th Cir. 2016). A plaintiff may
    establish discriminatory purpose by “‘produc[ing] direct or
    circumstantial evidence demonstrating that a discriminatory
    reason more likely tha[n] not motivated’ the defendant and
    that the defendant’s actions adversely affected the plaintiff
    in some way.” 
    Id.
     (quoting Pac. Shores Props., LLC v. City
    of Newport Beach, 
    730 F.3d 1142
    , 1158 (9th Cir. 2013)).
    Where direct evidence is unavailable, plaintiffs can, and
    frequently do, rely on the burden-shifting framework set out
    in McDonnell Douglas Corp. v. Green, 
    411 U.S. 792
     (1973),
    as a way of channeling inquiry into the available
    circumstantial evidence. That framework originated in cases
    interpreting Title VII of the Civil Rights Act of 1964, which
    prohibits employment discrimination based on “race, color,
    religion, sex, or national origin,” 42 U.S.C. § 2000e-2, but
    its use has since expanded to other discrimination statutes
    and to constitutional equal protection, see, e.g., Anthoine v.
    14                 BALLOU V. MCELVAIN
    N. Cent. Cntys. Consortium, 
    605 F.3d 740
    , 753 (9th Cir.
    2010).
    Under McDonnell Douglas, a plaintiff may make out a
    prima facie case of discrimination by demonstrating that
    “(1) she is a member of a protected class; (2) she was
    qualified for her position; (3) she experienced an adverse
    employment action; and (4) similarly situated individuals
    outside her protected class were treated more favorably.”
    Freyd v. Univ. of Oregon, 
    990 F.3d 1211
    , 1228 (9th Cir.
    2021) (alterations adopted) (quoting Fonseca v. Sysco Food
    Servs. of Ariz., Inc., 
    374 F.3d 840
    , 847 (9th Cir. 2004))
    (applying McDonnell Douglas in the Title VII context).
    Once a plaintiff has established a prima facie case, the
    burden shifts to the defendant to “show a legitimate,
    nondiscriminatory reason for the challenged actions.” 
    Id.
     If
    he is able to do so, the burden “returns to the plaintiff, who
    must show that the proffered nondiscriminatory reason is
    pretextual.” 
    Id.
    Ballou has established a prima facie claim for disparate
    treatment. It is undisputed that once Ballou was listed
    among the top three candidates on the sergeant list, she was
    eligible for promotion but was passed over for that
    promotion several times in favor of male candidates. One
    male officer, Ruder, was promoted to the same rank sought
    by Ballou—sergeant—despite having been investigated for
    precisely the same policy violation for which Ballou was
    investigated. Two other officers were promoted to corporal,
    a lower rank than sergeant, despite arguably more egregious
    violations. The record also indicates that Ballou was
    subjected to repeated internal affairs investigations for
    failure to write up reports on incidents, while male officers
    were not routinely subjected to investigations for the same
    conduct, and that the investigations became a purported
    BALLOU V. MCELVAIN                         15
    reason she was not promoted. Drawing all facts and
    inferences in her favor, Ballou has readily established the
    “minimal” degree of proof required to establish a prima facie
    case for discrimination. Wallis v. J.R. Simplot Co., 
    26 F.3d 885
    , 889 (9th Cir. 1994) (applying McDonnell Douglas in
    the Title VII context).
    As Ballou has established a prima facie case, the burden
    shifts    to   McElvain      to    articulate    “legitimate,
    nondiscriminatory reason[s]” for the actions Ballou
    challenges. Freyd, 990 F.3d at 1228. In his motion for
    summary judgment, McElvain asserted that Ballou was not
    promoted because she “failed a basic function of policing,
    gave conflicting explanations for her actions, and was soon
    under investigation for allegations of the identical
    misconduct.” Ballou does not dispute that these reasons, if
    true and complete, would be legitimate, nondiscriminatory
    bases for non-promotion, so we shall assume that they are.
    At the third McDonnell Douglas step, Ballou presented
    evidence that McElvain’s stated reasons for not promoting
    her were “false” and “based on sex stereotypes.”
    “Determining whether invidious discriminatory purpose was
    a motivating factor” for a government action “demands a
    sensitive inquiry into” the available evidence, including the
    “background” and “specific sequence of events leading up
    to the challenged decision,” “[d]epartures from the normal
    procedural sequence,” and “contemporary statements” by
    the decision maker. Village of Arlington Heights v. Metro.
    Hous. Dev. Corp., 
    429 U.S. 252
    , 266–68 (1977).
    Here, normal procedure was for McElvain to promote
    the highest-ranked candidate on the sergeant list. Drawing
    all inferences in Ballou’s favor, the record indicates that it
    was not normal department procedure to initiate a broad
    internal affairs investigation into an officer for failing to file
    16                 BALLOU V. MCELVAIN
    a report. Furthermore, the record shows that McElvain’s
    request for an expanded investigation into Ballou’s conduct
    occurred close in time to when Ballou became the first
    woman in McElvain’s tenure to be eligible for promotion to
    sergeant.
    The record testimony regarding internal departmental
    discussions about Ballou further supports her contention that
    McElvain’s articulated reasons for failing to promote her
    was pretextual. Two women officers who had met with
    McElvain in July of 2018 testified that they had specifically
    identified both the internal affairs investigations into Ballou
    and the decision not to promote her as examples of
    discriminatory practices in the department. They and other
    officers who attended the meeting expressed concerns about
    what they perceived as a discriminatory department culture,
    labelled the department’s conduct as “disparate treatment,”
    and identified Ruder as a “white male comparator” who had
    been treated more favorably than Ballou. Within a day of
    this discussion, in which he was urged to “take some time”
    to reflect on possible discrimination in the department,
    McElvain announced the promotion of Jennings over
    Ballou. This sequence of events, together with the departure
    from standard department procedure, indicates that
    McElvain was at best unconcerned about allegations of
    discrimination in the department.
    Additionally, the district court determined that the
    comparators Ballou identified were sufficiently similar to
    her to support an inference of disparate treatment. To
    establish similarity under the McDonnell Douglas
    framework, the individuals being compared “need not be
    identical; they must only be similar ‘in all material
    respects.’” Hawn v. Exec. Jet Mgmt., Inc., 
    615 F.3d 1151
    ,
    1157 (9th Cir. 2010) (quoting Moran v. Selig, 
    447 F.3d 748
    ,
    BALLOU V. MCELVAIN                        17
    755 (9th Cir. 2006)) (applying McDonnell Douglas to a Title
    VII claim). Generally, “individuals are similarly situated
    when they have similar jobs and display similar conduct.”
    Vasquez v. Cnty. of Los Angeles, 
    349 F.3d 634
    , 641 (9th Cir.
    2003).
    Here, Ruder held the same position as Ballou when he
    applied for promotion and was promoted to sergeant—the
    same promotion Ballou sought. Likewise, Ruder and Ballou
    “display[ed] similar conduct.” 
    Id.
     Although Vasquez held
    that officers not accused of “problematic conduct of
    comparable seriousness” might not be so similarly situated
    as to sustain a case for discrimination under Title VII, 
    id.,
     in
    this case Ballou and Ruder were both accused of the same
    conduct: failure to write a report. Ruder is therefore
    sufficiently “similarly situated” to support an inference of
    discriminatory intent.
    In sum, the district court concluded that whether
    McElvain’s stated reasons for not promoting Ballou were
    “valid and non-discriminatory . . . raises numerous questions
    of fact precluding summary judgment.” Again, we may not
    review that conclusion in the present procedural posture. See
    Estate of Anderson, 985 F.3d at 730–31. Assuming, as we
    must when reviewing a denial of qualified immunity at
    summary judgment, that these factual disputes are resolved
    in Ballou’s favor, id. at 731, the record supports the
    conclusion that McElvain’s articulated reasons for not
    promoting Ballou were pretextual and that Ballou has thus
    established a disparate treatment claim under the Equal
    Protection Clause.
    ii.
    McElvain argues vigorously that Ballou’s disparate
    treatment claim nonetheless cannot succeed because the
    18                 BALLOU V. MCELVAIN
    male police officers Ballou points to as comparators for her
    claim are not sufficiently similar to Ballou to demonstrate
    discrimination. He asserts that “proof of discriminatory
    animus alone will not suffice to establish an equal protection
    violation,” as “proof that others similarly situated in a
    constitutional sense were treated more favorably is an
    essential element” of such a claim. Because, he argues,
    Ballou has not pointed to any male officer “arguably
    indistinguishable from Ballou in terms of being promoted to
    sergeant despite recent sustained misconduct,” she cannot
    state a claim under the Equal Protection Clause, even if she
    has presented sufficient evidence that the reason she was not
    promoted was that she is a woman—that is, that had she been
    a man, she would have been promoted earlier than she was.
    McElvain’s account of the requirements for making out
    an Equal Protection claim is profoundly incorrect, as it is
    squarely contrary both to our precedents and to the basic
    precepts underlying the Equal Protection Clause.
    The central inquiry in any disparate treatment claim
    under the Equal Protection Clause is whether “an ‘invidious
    discriminatory purpose was a motivating factor’” in some
    government action. Ave. 6E Invs., 818 F.3d at 504 (quoting
    Arlington Heights, 
    429 U.S. at 266
    ) (applying this standard
    to claims under both the Equal Protection Clause and the Fair
    Housing Act, 
    42 U.S.C. § 3601
     et seq.). A plaintiff may
    make out a disparate treatment claim by “simply produc[ing]
    direct or circumstantial evidence demonstrating that” a
    government action was motivated by a discriminatory
    purpose. 
    Id.
     (quoting Pac. Shores, 730 F.3d at 1158).
    “[A]ny indication of discriminatory motive may suffice” to
    allow a disparate treatment claim to survive summary
    judgment. Arce v. Douglas, 
    793 F.3d 968
    , 978 (9th Cir.
    BALLOU V. MCELVAIN                             19
    2015) (emphasis added) (quoting Pac. Shores, 730 F.3d
    at 1159).
    Plaintiffs bringing disparate treatment claims, either
    under the Equal Protection Clause or under
    antidiscrimination statutes, may, as we have explained,
    supra at 13–14, point to comparators as circumstantial
    evidence of unlawful discriminatory intent. But a relevant
    comparator is not an element of a disparate treatment claim.
    As our precedent makes clear, the existence of a comparator
    “is only one way to survive summary judgment on a
    disparate treatment claim.” Pac. Shores Props., 730 F.3d
    at 1158 (citing McDonnell Douglas, 
    411 U.S. 792
    ); see also
    Purtue v. Wis. Dep’t of Corr., 
    963 F.3d 598
    , 602 (7th Cir.
    2020). 1 With or without comparator evidence, courts
    determine whether a government action was motivated by
    discriminatory purpose by engaging in the “sensitive inquiry
    into such circumstantial and direct evidence of intent as may
    be available.” De La Cruz v. Tormey, 
    582 F.2d 45
    , 59 (9th
    Cir. 1978) (quoting Arlington Heights, 
    429 U.S. at 266
    ).
    McElvain insists otherwise—that “to state an equal
    protection claim of any stripe . . . a plaintiff must show that
    the defendant treated the plaintiff differently from similarly
    situated individuals,” pointing to Pimentel v. Dreyfus,
    
    670 F.3d 1096
    , 1106 (9th Cir. 2012) (per curiam) (emphasis
    added). In so arguing, McElvain misunderstands the
    1
    Pacific Shores Properties analyzed the disparate treatment claim
    through the lens of the Fair Housing Act. But Avenue 6E Investments
    clarified that “[i]f a governmental actor engages in . . . discrimination
    [under the Fair Housing Act], such conduct also violates the Equal
    Protection Clause,” 818 F.3d at 502 (citing Arlington Heights, 
    429 U.S. at
    265–66), and that the inquiry into whether disparate treatment has
    occurred is the same under both the Fair Housing Act and the Equal
    Protection Clause, see id. at 504.
    20                  BALLOU V. MCELVAIN
    significance of Pimentel and also of Furnace v. Sullivan,
    
    705 F.3d 1021
     (9th Cir. 2013), another case on which
    McElvain relies for his novel proposition.
    In Pimentel, we denied a preliminary injunction against
    Washington State’s termination of state-funded food
    assistance for certain noncitizens. See 670 F.3d at 1098,
    1106. In so doing, we held that the state had not engaged in
    discrimination, because the repeal of a state measure
    adopted to benefit a certain class, without more, does not
    necessarily constitute discrimination. See id. at 1107.
    Because we held the plaintiffs had not stated an equal
    protection claim, we declined to apply strict scrutiny to the
    state’s action. Id. at 1106. The language cited by McElvain
    appears in the portion of the discussion rejecting an equal
    protection claim based solely on repeal of a beneficial
    provision; it stands only for the proposition that “[i]n the
    absence of an equal protection claim, consideration of the
    level of scrutiny . . . necessarily falls out of the analysis.” Id.
    Pimentel did not address, and should not be read as
    disturbing, Supreme Court and circuit case law establishing
    that comparator evidence is not an essential element of a
    disparate treatment claim.
    In Furnace, we held that the plaintiff had not stated an
    Equal Protection claim because he did not establish that he
    was part of a class that was being discriminated against. See
    705 F.3d at 1030–31. The plaintiff’s failure to point to other
    “similarly situated” individuals was fatal because he was not
    able to identify the “factor motivating the alleged
    discrimination.” Id. at 1030 (quoting Thornton v. City of St.
    Helens, 
    425 F.3d 1158
    , 1167 (9th Cir. 2005)). No such
    problem exists here.         Ballou alleges that she was
    discriminated against on the basis of sex, and it is undisputed
    that sex is a protected classification under the Equal
    BALLOU V. MCELVAIN                      21
    Protection Clause. See Frontiero v. Richardson, 
    411 U.S. 677
    , 682 (1973). The cases McElvain cites are therefore
    inapposite.
    McElvain’s account of the protections of the Fourteenth
    Amendment, in addition to being wrong as a matter of law,
    is contrary to the amendment’s fundamental guarantee of
    “equal protection of the laws.” U.S. Const. amend. XIV, § 1.
    Under McElvain’s reading of the Fourteenth Amendment,
    no plaintiff could state an equal protection claim “of any
    stripe” without an identical comparator, no matter how
    strong the direct or circumstantial evidence that the reason
    the plaintiff was detrimentally treated was her sex—or, for
    that matter, her race. This view of the Constitution’s
    protections would sweep so broadly as to undermine decades
    of Supreme Court case law striking down government
    actions “taken for invidious purposes.” Arlington Heights,
    
    429 U.S. at 267
    ; see 
    id.
     (collecting cases). Applied to the
    present case, McElvain’s account of the scope of the Equal
    Protection Clause would mean that, had Ballou presented an
    audio recording of McElvain stating that he was declining to
    promote Ballou specifically because she was a woman and
    that, moreover, he would never promote a woman to
    sergeant, this evidence would not support a disparate
    treatment claim unless he promoted an identical male
    comparator.
    As this example confirms, McElvain’s account of Equal
    Protection law is profoundly mistaken. The existence of a
    comparator is not a prerequisite to stating a disparate
    treatment claim under the Fourteenth Amendment. To the
    contrary, comparator evidence in disparate treatment claims
    can, but need not, be used to support a finding of a
    discriminatory motive. It is not a gatekeeping mechanism
    essential to plaintiffs’ ability to prove that they have been
    22                BALLOU V. MCELVAIN
    denied equal protection of the laws by being adversely
    treated on the basis of membership in a protected class. See
    Trans World Airlines, Inc. v. Thurston, 
    469 U.S. 111
    , 121
    (1985).
    iii.
    The remaining question on the sex discrimination
    disparate treatment claim is whether, assuming all factual
    disputes are resolved in Ballou’s favor, McElvain is entitled
    to qualified immunity. See Estate of Anderson, 985 F.3d
    at 731. He is not.
    It is well established that the Equal Protection Clause
    “prohibit[s] state actors from engaging in intentional
    conduct designed to impede a person’s career advancement
    because of her gender.” Lindsey v. Shalmy, 
    29 F.3d 1382
    ,
    1385 (9th Cir. 1994). This prohibition guarantees state
    employees “a clearly established constitutional right not to
    be refused employment because of their sex,” and to be free
    from “denial of a promotion, adverse alteration of job
    responsibilities, and other hostile treatment” in the
    workplace on account of sex. Bator v. State of Hawai‘i,
    
    39 F.3d 1021
    , 1028 (9th Cir. 1994) (citing Lowe v. City of
    Monrovia, 
    775 F.3d 998
    , 1011 (9th Cir. 1985) and Lindsey,
    
    29 F.3d at
    1385–86). Ballou contends that McElvain denied
    her promotion at least in part on account of her sex; the
    conduct she alleges falls squarely within the constitutional
    prohibition outlined in Lindsey and Bator.
    Given Lindsey and Bator, McElvain is not entitled to
    qualified immunity on the claim that he discriminatorily
    denied Ballou a promotion. It is “apparent in light of . . .
    pre-existing law,” Benavidez, 993 F.3d at 1152 (quoting
    Devereaux, 
    218 F.3d at 1053
    ), that discriminatorily
    instigating an internal investigation against a public
    BALLOU V. MCELVAIN                      23
    employee violates that individual’s constitutional rights. In
    holding that discriminatory employment actions by a public
    employer against a state employee violate that employee’s
    constitutional rights, Lindsey specifically identified
    “unfavorably altering . . . job assignments,” “unfavorable
    performance evaluations” and “displaying a hostile attitude”
    toward a plaintiff as examples of adverse employment
    actions that, if taken with a discriminatory purpose, would
    violate an employee’s “clearly established federal
    constitutional rights.” 
    29 F.3d at 1386
    .
    The actions alleged here are so closely analogous to
    those identified in Lindsey and so clearly covered by Bator’s
    focus on promotion that any reasonable officer would
    recognize discriminatorily conducting an investigation to
    stall a promotion as unconstitutional under the two cases,
    read in combination. Ballou contends that McElvain
    initiated several investigations charging Ballou with
    misconduct. These investigations became the stated grounds
    for denying Ballou a promotion to which she was otherwise
    entitled, thus directly limiting her career progression. The
    investigations had a direct material impact on her
    employment, by blocking her path to promotion.
    McElvain is therefore not entitled to qualified immunity
    on the claim that he encouraged and sustained discriminatory
    investigations into Ballou’s workplace performance and
    thereby denied her promotion at least in part on the basis of
    sex. As Ballou’s disparate treatment claim alleged that
    McElvain violated her clearly established rights under the
    Equal Protection Clause, McElvain is not entitled to
    qualified immunity on that claim.
    24                 BALLOU V. MCELVAIN
    B. Fourteenth Amendment Retaliation
    McElvain next asks us to consider whether he is entitled
    to qualified immunity on the claim that he violated Ballou’s
    rights under the Equal Protection Clause of the Fourteenth
    Amendment by “retaliating against her for opposing
    Defendants’ sex discrimination.” Because our jurisdiction
    under the collateral order doctrine is limited to reviewing a
    denial of qualified immunity, and because we cannot discern
    from the district court’s order whether it granted, denied, or
    did not address McElvain’s assertion of qualified immunity
    as to Ballou’s Equal Protection retaliation claim, we remand
    to the district court to clarify its order as to that claim.
    The district court’s dispositions, both on the motion for
    partial judgment on the pleadings and on the motion for
    summary judgment, addressed McElvain’s assertion of
    qualified immunity, as it applied to Ballou’s claims, only
    briefly. In the order denying partial judgment on the
    pleadings, the district court stated, with respect to Ballou’s
    First Amendment retaliation claim, that it is clearly
    established “that complaints of gender discrimination
    against a public employer are matters of public concern.”
    Then, addressing McElvain’s assertion of qualified
    immunity generally, the district court stated only that
    McElvain knew or should have known “that sexually
    discriminating against an employee and retaliating against
    her for voicing her concerns, violates her clearly established
    constitutional rights.” The district court did not so state with
    regard to the Equal Protection retaliation claim in particular.
    In his motion for summary judgment, addressing the
    merits of Ballou’s Equal Protection retaliation claim,
    McElvain argued that the district court should reject that
    claim because “there is no binding Ninth Circuit case on
    point,” but in the portion of his brief addressing qualified
    BALLOU V. MCELVAIN                        25
    immunity, he did not specifically assert qualified immunity
    as to Ballou’s Equal Protection retaliation claim. Instead, he
    argued generally that, while “as a general matter, the Equal
    Protection Clause prohibits discrimination, and the First
    Amendment prohibits retaliation,” he was entitled to
    qualified immunity on the “more particularized” questions
    whether Ballou’s failure “to take a police report is a
    sufficient basis to decline to promote her to a supervisory
    position” and “whether Ballou’s original lawsuit is
    constitutionally protected.”
    Apparently reflecting the structure of the arguments
    advanced in McElvain’s motion, the district court’s
    summary judgment order stated generally, as to qualified
    immunity, that “the Equal Protection Clause prohibits
    discrimination, and . . . the First Amendment prohibits
    retaliation.” Noting that this qualified immunity argument
    “was the subject of a prior Motion and Order,” the district
    court denied McElvain’s motion for summary judgment on
    qualified immunity. Although this portion of the district
    court’s order could be read as denying qualified immunity as
    to all of Ballou’s claims, other parts of the district court’s
    order indicate otherwise.
    Specifically, in addressing the merits of Ballou’s Equal
    Protection retaliation claim, the district court stated that the
    viability of such a claim is a “close question,” noting that
    “there is not a Ninth Circuit (or Supreme Court) case[] flatly
    holding that Equal Protection does not apply to a retaliation
    claim.” In contrast to the part of the district court’s order
    addressing qualified immunity, this reasoning indicates that
    the district court believed the law had not clearly established
    the right asserted by Ballou. The absence of a case denying
    a right cannot establish clearly that there is such a right, nor
    would there be a “close question” on the merits if the
    26                 BALLOU V. MCELVAIN
    pertinent law were clearly established. So the district court’s
    analysis of the merits of the Equal Protection retaliation
    claim is inconsistent with denying qualified immunity on
    that claim.
    Taking that analysis together with the holdings, we
    cannot discern whether the district court granted, denied, or
    simply did not address McElvain’s assertion of qualified
    immunity on Ballou’s Equal Protection retaliation claim. On
    the one hand, the bottom line of the district court’s summary
    judgment order generally denied qualified immunity and did
    not specifically carve out Ballou’s Equal Protection
    retaliation claim. Without more, that conclusion could
    suggest the district court intended to deny qualified
    immunity as to all of Ballou’s claims. But the district court
    did say more. Specifically, the district court’s qualified
    immunity analysis—like McElvain’s motion—stated that
    “the Equal Protection Clause prohibits discrimination” and
    “the First Amendment prohibits retaliation,” without
    addressing whether the Equal Protection Clause clearly
    prohibits retaliation. And as to that claim, the district
    court—addressing the merits of Ballou’s Equal Protection
    retaliation claim—indicated that there is not clearly
    established law on that constitutional issue, a conclusion
    consistent with granting qualified immunity to McElvain on
    that claim.
    Our jurisdiction under the collateral order doctrine is
    limited to reviewing a denial of qualified immunity. See
    Plumhoff, 572 U.S. at 771–72; Foster, 908 F.3d at 1209–10.
    Where, as here, “we cannot tell for sure” what action the
    district court took with respect to McElvain’s assertion of
    qualified immunity, “we must either try to discern from the
    record” what the district court did “or remand for the district
    court to explain its reasoning.” Maropulos v. Cnty. of Los
    BALLOU V. MCELVAIN                       27
    Angeles, 
    560 F.3d 974
    , 975 (9th Cir. 2009) (per curiam).
    Accordingly, rather than venture a guess about our
    jurisdiction, we remand to the district court to clarify what
    action, if any, it took with respect to Ballou’s Equal
    Protection retaliation claim.
    C. First Amendment Retaliation
    Finally, Ballou contends that McElvain violated her
    rights under the Petition Clause of the First Amendment by
    maintaining repeated internal affairs investigations into her
    work practices and promoting Ruder over her, in retaliation
    for her opposition to sex discrimination in the workplace.
    McElvain’s counters are that he is entitled to qualified
    immunity on Ballou’s First Amendment claims because
    (1) the law does not clearly establish that her speech was on
    a matter of public concern and (2) the forms of her
    opposition—on his account, internal complaints and state-
    law tort claims—were not clearly constitutionally protected.
    And, McElvain further contends, the record does not support
    the conclusion that Ballou’s speech was a cause of the
    adverse employment actions. Each of these arguments fails
    at this stage.
    First, the content of Ballou’s expression is clearly
    protected by the First Amendment. It is long established,
    and McElvain does not dispute, that the First Amendment
    protects a public employee’s right to speak out against or
    petition the government—including via a lawsuit—on
    “matters of public concern.” Pickering v. Bd. of Educ.,
    
    391 U.S. 563
    , 574 (1968). “Whether an employee’s speech
    addresses a matter of public concern must be determined by
    the content, form, and context” of the expression, Connick v.
    Myers, 
    461 U.S. 138
    , 147–48 (1983), with content weighing
    as the “greatest single factor” in the analysis, Ulrich v. City
    & Cnty. of San Francisco, 
    308 F.3d 968
    , 979 (9th Cir. 2002)
    28                 BALLOU V. MCELVAIN
    (quoting Havekost v. U.S. Dep’t of the Navy, 
    925 F.2d 316
    ,
    318 (9th Cir. 1991)).
    McElvain maintains that Ballou here seeks to
    “constitutionalize the employee grievance,” and that her
    complaints and lawsuit pertain only to matters of private,
    rather than public, concern. See Borough of Duryea v.
    Guarnieri, 
    564 U.S. 379
    , 392 (2011) (quoting Garcetti v.
    Ceballos, 
    547 U.S. 410
    , 420 (2006)). Our circuit case law
    squarely forecloses McElvain’s position. Public employees’
    expression is on a matter of public concern if it “relat[es] to
    any matter of political, social, or other concern to the
    community,” Barone v. City of Springfield, 
    902 F.3d 1091
    ,
    1102 (9th Cir. 2018) (quoting Lane v. Franks, 
    573 U.S. 228
    ,
    241 (2014)), and not “upon matters only of personal
    interest.” Rendish v. City of Tacoma, 
    123 F.3d 1216
    , 1223
    (9th Cir. 1997) (emphasis added) (quoting Connick, 
    461 U.S. at 147
    ). Some subjects both affect a public employee’s
    personal interests and implicate matters of public concern.
    Rendish held that unlawful discrimination is such a matter,
    recognizing that “the public has an interest in unlawful
    discrimination” in City government, and that employee
    speech about such discrimination therefore involves matters
    of public concern even if it arises out of a personal dispute.
    Id. at 1224.
    We reiterated this principle in Alpha Energy Savers, Inc.
    v. Hansen, 
    381 F.3d 917
     (9th Cir. 2004). Alpha Energy held
    that “when government employees speak about . . .
    wrongdoing [or] misconduct . . . by other government
    employees, . . . their speech is inherently a matter of public
    concern.” 
    Id. at 926
     (final ellipsis in original) (quoting
    Ceballos v. Garcetti, 
    361 F.3d 1168
    , 1174 (9th Cir. 2004),
    rev’d, 
    547 U.S. 410
     (2006)). And Alpha Energy clarified
    that:
    BALLOU V. MCELVAIN                             29
    Th[is]      rule     applies     to   invidious
    discrimination as well . . . . Disputes over
    racial, religious, or other such discrimination
    by public officials are not simply individual
    personnel matters.       They involve the type
    of governmental conduct that affects the
    societal interest as a whole—conduct
    in which the public has a deep and abiding
    interest. Litigation seeking to expose such
    wrongful governmental activity is, by its very
    nature, a matter of public concern.
    
    Id.
     at 926–27. This rule applies to both administrative and
    judicial proceedings seeking to “bring to light potential or
    actual discrimination” by government officials, 
    id.
     at 925
    (citing Lytle v. Wondrash, 
    182 F.3d 1083
    , 1087–88 (9th Cir.
    1999)); see Rendish, 
    123 F.3d at
    1223–24, and controls even
    when the plaintiff seeks only private relief for the
    vindication of her own rights, see Rendish, 
    123 F.3d at 1224
    . 2 This precedent clearly establishes that speech by
    public employees about unlawful discrimination in the
    workplace is inherently speech on a matter of public
    concern. 3
    2
    In so holding, Alpha Energy Savers explicitly rejected the Seventh
    Circuit’s reasoning in Yatvin v. Madison Metro Sch. Dist., 
    840 F.2d 412
    (7th Cir. 1988), on which McElvain relies. See 
    381 F.3d at 926
    .

    McElvain argues that our precedent has been cast into doubt by the
    Supreme Court’s decision in Borough of Duryea v. Guarnieri, 
    564 U.S. 379
     (2011), which was decided after Alpha Energy. We do not agree
    with McElvain’s reading of Borough of Duryea. That case held only that
    the “public concern” test outlined in Connick applies to suits under the
    Petitions Clause, and that courts should apply the same framework used
    in Speech Clause claims to assess claims brought under the Petitions
    30                    BALLOU V. MCELVAIN
    What’s more, the record in this case demonstrates that
    Ballou’s allegations concerned considerably more than a
    personal matter. The Vancouver Police Department’s
    treatment of Ballou generated concern and involvement
    among other police officers. As a result of that concern,
    several of them met with McElvain to discuss perceived
    discriminatory practices in their workplace. Also, Ballou’s
    lawsuit was the subject of at least one news story in the local
    press. Thus, even if speech alleging discrimination in a
    public workplace were not inherently a matter of public
    concern—which, as explained supra, our case law
    establishes it is—there is sufficient evidence in the record,
    drawing all inferences in Ballou’s favor, Estate of Anderson,
    985 F.3d at 731, to conclude that the specific expression at
    issue here was on a matter of more than private concern. We
    therefore reject the argument that the content of Ballou’s
    speech is not protected by the First Amendment.
    McElvain’s contention to the contrary notwithstanding,
    the form of Ballou’s expression is likewise protected by the
    First Amendment under clearly established law. The
    Petition Clause prohibits retaliating against public
    employees for filing lawsuits. See Rendish, 
    123 F.3d at
    1219–23; Alpha Energy, 
    381 F.3d at 925
    . The parties
    dispute, as a question of fact, whether McElvain was aware
    of Ballou’s federal suit when he passed her over for
    promotion in favor of Ruder. Ballou first filed her federal
    lawsuit on January 3, 2019, a week before McElvain
    promoted Ruder over her. She served it on January 10.
    McElvain contends he decided to promote Ruder before he
    learned of the lawsuit. But even if that were so, the record
    Clause. See 
    id.
     at 393–95, 398. Borough of Duryea therefore reinforces,
    rather than undermines, the relevance of our precedent addressing when
    expression involves a matter of public concern.
    BALLOU V. MCELVAIN                        31
    nevertheless shows at least one internal affairs investigation
    was opened against Ballou after she filed her federal
    complaint. If, at trial, the jury finds that McElvain retaliated
    in that respect against Ballou for filing this federal suit, that
    retaliation would violate Ballou’s clearly established rights
    under the Petition Clause.
    McElvain is not entitled to qualified immunity on
    Ballou’s First Amendment claims at this stage of the
    litigation for another reason as well. McElvain does not
    dispute that he was aware of Ballou’s state tort-claim notices
    alleging sex discrimination, filed in the autumn of 2018,
    several months before Ruder’s promotion.                 Under
    Washington law, the service of a state tort notice is a
    necessary first step in filing suit against a local government
    entity. 
    Wash. Rev. Code § 4.96.020
    . As a statutory
    prerequisite to filing a state-court action, such notices are
    part and parcel of formal litigation proceedings. And, as
    established in Rendish, the Petition Clause of the First
    Amendment protects the initiation of a state-court lawsuit by
    a public employee on a matter of public concern. See
    
    123 F.3d at 1218
    , 1223–25.              Filing a mandatory
    administrative complaint to initiate state-court litigation is
    thus no doubt a form of speech protected by the Petition
    Clause.
    Finally, McElvain contends that Ballou has not
    established causation—i.e., that she has failed to establish
    that any adverse employment actions she suffered were
    because of her opposition to sex discrimination in her public
    workplace. We lack jurisdiction to address this question.
    The district court found that there were disputed questions
    of material fact sufficient to deny summary judgment to
    McElvain on the causation aspect of the retaliation claim.
    We may review that denial of summary judgment only if
    32                 BALLOU V. MCELVAIN
    Ballou’s version of events is “blatantly contradicted by the
    record.” Orn, 949 F.3d at 1171 (quoting Scott, 
    550 U.S. at 380
    ). It is not.
    Ballou contends, as part of her retaliation claim, that she
    was subjected to unwarranted internal affairs investigations
    in response to her opposition to sex discrimination. The
    record indicates that several internal affairs investigations
    were initiated against Ballou after McElvain became aware
    of the action underlying this suit. Likewise, the record
    supports the conclusion that McElvain was aware of
    Ballou’s internal complaints and state-court claims when he
    passed her over for promotion in favor of Ruder.
    Whether Ballou’s protected expression actually was the
    but-for cause of the adverse employment actions goes to the
    ultimate question of liability and must be resolved by the
    jury at trial. But it does not bear on the question before us
    now—whether retaliating against Ballou for that expression
    would, as a matter of law, violate her clearly established
    constitutional rights. Because Ballou’s factual account is not
    “blatantly contradicted by the record,” 
    id.,
     we may not
    disturb the district court’s determination that Ballou’s
    retaliation claims were sufficiently supported to survive
    summary judgment.
    We therefore affirm the denial of qualified immunity to
    McElvain on Ballou’s First Amendment claims.
    III.
    Because we cannot discern whether the district court
    denied McElvain qualified immunity on Ballou’s claim that
    she was retaliated against in violation of the Fourteenth
    Amendment’s Equal Protection Clause, we remand to the
    district court to clarify its summary judgment order on that
    BALLOU V. MCELVAIN                   33
    issue. For the reasons explained, we hold that McElvain is
    not entitled to qualified immunity on Ballou’s remaining
    claims. We therefore affirm the district court’s denial of
    qualified immunity on Ballou’s Equal Protection sex
    discrimination and First Amendment claims.
    AFFIRMED; REMANDED.
