    RICHARDSON, Circuit Judge:
    Dr. Jane DiCocco brought Title VII and Age Discrimination in Employment Act
    (“ADEA”) claims against the U.S. Attorney General because she failed an allegedly
    discriminatory physical-fitness test that was a condition of her federal employment and
    was told to either retake the test, resign, or be fired. She resigned. The district court
    dismissed her complaint for lack of Article III standing, finding that her resignation did not
    constitute an “adverse employment action” that could serve as the basis of either claim.
    But the district court inappropriately intertwined its standing analysis with the
    merits. Dr. DiCocco alleged that she suffered financial and job-related injuries in fact that
    are fairly traceable to the government’s action and likely to be redressed by a favorable
    ruling. See Lujan v. Defs. of Wildlife, 
    504 U.S. 555
    , 560 (1992). So she has Article III
    standing. But we must still dismiss her ADEA claim because the ADEA provision
    applicable to federal-sector employees does not provide a disparate-impact cause of action.
    So her claim does not fall within the government’s waiver of sovereign immunity. We
    decline, however, to address arguments for rejecting her remaining Title VII claim under
    Rule 12(b)(6). We therefore affirm the district court’s dismissal of the ADEA claim but
    remand the Title VII claim for further proceedings.
    I.      Background
    In July 2014, Dr. Jane DiCocco accepted a job as a psychiatrist with the Bureau of
    Prisons (“BOP”) at the Federal Correctional Complex in Petersburg, Virginia. At that time,
    Dr. DiCocco was sixty-seven years old.
    2
    USCA4 Appeal: 20-1342      Doc: 29          Filed: 11/17/2021     Pg: 3 of 47
    As a condition of her hiring, Dr. DiCocco—like all new BOP employees regardless
    of age, position, or gender—had to take and pass the Physical Abilities Test. Employees
    taking the test must drag a seventy-five-pound dummy at least 694 feet for three minutes,
    climb a ladder to retrieve an object within seven seconds, complete an obstacle course in
    fifty-eight seconds, run a quarter mile and handcuff someone within two minutes and
    thirty-five seconds, and climb three flights of stairs in forty-five seconds while wearing a
    twenty-pound weight belt. Employees receive scores for the five components, which are
    aggregated and measured against a passing composite score.
    The first time Dr. DiCocco took the test, she failed. Under BOP policy, she could
    retake the test within twenty-four hours, but she declined, “fearing that in her exhausted
    physical condition, she would be unable [to] complete it in a satisfactory time during the
    second attempt.” J.A. 7. She was then “informed that unless she resigned, her employment
    with BOP would be terminated for failure to pass the [test] within the required times.” 
    Id.
    She chose to resign.
    After exhausting her administrative remedies, Dr. DiCocco filed a complaint in
    federal district court against the Attorney General, alleging disparate-impact theories of
    sex discrimination under Title VII, 42 U.S.C. §§ 2000e to 2000e-17, and age discrimination
    under the ADEA, 
    29 U.S.C. §§ 621
    –634. The government moved to dismiss her complaint
    under Federal Rule of Civil Procedure 12(b)(1) for lack of subject-matter jurisdiction and
    Rule 12(b)(6) for failure to state a claim. The district court dismissed the complaint without
    prejudice for lack of standing, finding that Dr. DiCocco had not suffered an injury in fact
    traceable to the BOP’s actions because the facts in her complaint did not constitute an
    3
    USCA4 Appeal: 20-1342       Doc: 29         Filed: 11/17/2021      Pg: 4 of 47
    “adverse employment action” under Title VII or the ADEA. DiCocco v. Barr, No. 3:19-
    cv-159, 
    2020 WL 902530
    , at *2–5 (E.D. Va. Feb. 25, 2020). Dr. DiCocco timely appealed.
    We have jurisdiction to hear her appeal under 
    28 U.S.C. § 1291
     because the standing
    defect identified by the district court could not have been cured by amendment. See Bing
    v. Brivo Sys., LLC, 
    959 F.3d 605
    , 610 (4th Cir. 2020).
    II.    Discussion
    We may affirm the district court’s dismissal on “any grounds apparent from the
    record.” Pitt Cnty. v. Hotels.com, L.P., 
    553 F.3d 308
    , 311 (4th Cir. 2009) (quoting Suter
    v. United States, 
    441 F.3d 306
    , 311 (4th Cir. 2006)). The Government raises three: (1)
    lack of Article III standing, (2) absence of a disparate-impact cause of action falling under
    the ADEA’s sovereign-immunity waiver, and (3) failure to state a claim under Title VII.
    We hold that Dr. DiCocco has standing but that the ADEA’s federal-employer provision
    does not include claims for disparate-impact liability. Finally, we remand the Title VII
    claim for consideration by the district court.
    A.     Standing
    We start with whether Dr. DiCocco has standing to bring both claims. See Steel Co.
    v. Citizens for a Better Env’t, 
    523 U.S. 83
    , 94 (1998). A plaintiff has Article III standing
    if she (1) suffers an injury in fact that is (2) fairly traceable to the challenged conduct and
    (3) likely to be redressed if the court rules in her favor. Lujan, 
    504 U.S. at 560
    . We review
    the district court’s dismissal for lack of standing de novo. Miller v. Brown, 
    462 F.3d 312
    ,
    316 (4th Cir. 2006).      Because the government brought a “facial” challenge to Dr.
    DiCocco’s standing, contending “that [the] complaint simply fails to allege facts upon
    4
    USCA4 Appeal: 20-1342       Doc: 29          Filed: 11/17/2021       Pg: 5 of 47
    which subject matter jurisdiction can be based,” we accept all well-pleaded facts in the
    complaint as true. Beck v. McDonald, 
    848 F.3d 262
    , 270 (4th Cir. 2017) (quoting Kerns v.
    United States, 
    585 F.3d 187
    , 192 (4th Cir. 2009)).
    The district court began its analysis by finding that Dr. DiCocco failed to state a
    valid cause of action because she alleged no injury and therefore lacked standing. DiCocco,
    
    2020 WL 902530
    , at *3–5. But this approach improperly conflated the threshold standing
    question with the merits of her claims. Pitt Cnty., 
    553 F.3d at 312
    . Standing does not turn
    on whether a plaintiff has definitively stated a valid cause of action. Id.; Lexmark Int’l,
    Inc. v. Static Control Components, Inc., 
    572 U.S. 118
    , 128 n.4 (2014) (“[T]he absence of
    a valid (as opposed to arguable) cause of action does not implicate subject-matter
    jurisdiction, i.e., the court’s statutory or constitutional power to adjudicate the case.”
    (quoting Verizon Md. Inc. v. Pub. Serv. Comm’n of Md., 
    535 U.S. 635
    , 642–43 (2002))).
    In other words, a valid claim for relief is not a prerequisite for standing. See, e.g., Trump
    v. Hawaii, 
    138 S. Ct. 2392
    , 2416 (2018) (rejecting an argument that plaintiffs lacked Article
    III standing because the Establishment Clause did not “give them a legally protected
    interest”). “For it is well settled that the failure to state a proper cause of action calls for a
    judgment on the merits and not for a dismissal for want of jurisdiction.” Bell v. Hood, 
    327 U.S. 678
    , 682 (1946).
    Dr. DiCocco has adequately pleaded an injury in fact. Dr. DiCocco alleges that she
    was injured by a loss of employment and the resulting loss of wages and other benefits.
    See J.A. 10–11. Such harms are “classic and paradigmatic” injuries for standing purposes.
    Air Evac EMS, Inc. v. Cheatham, 
    910 F.3d 751
    , 760 (4th Cir. 2018) (quoting Cottrell v.
    5
    USCA4 Appeal: 20-1342        Doc: 29          Filed: 11/17/2021       Pg: 6 of 47
    Alcon Lab’ys, 
    874 F.3d 154
    , 163 (3d Cir. 2017)); see also Howard R.L. Cook & Tommy
    Shaw Found. ex rel. Black Emps. of Libr. of Congress, Inc. v. Billington, 
    737 F.3d 767
    ,
    770–73 (D.C. Cir. 2013) (plaintiffs had Article III standing to bring Title VII retaliation
    claim based on the alleged denial of certain benefits, but still failed to state a claim because
    the complaint did not allege that any plaintiff engaged in a statutorily protected activity
    leading to a materially adverse action).
    To satisfy standing’s causation requirement, the alleged injury must be
    “fairly . . . trace[able] to the challenged action of the defendant, and not . . . th[e] result [of]
    the independent action of some third party not before the court.” Lujan, 
    504 U.S. at 560
    (alterations in original) (quoting Simon v. E. Ky. Welfare Rts. Org., 
    426 U.S. 26
    , 41–42
    (1976)). At the motion-to-dismiss stage, this burden is “relatively modest,” Bennett v.
    Spear, 
    520 U.S. 154
    , 171 (1997), and lower than the causation showing required to prevail
    in a tort suit, Nat. Res. Def. Council, Inc. v. Watkins, 
    954 F.2d 974
    , 980 n.7 (4th Cir. 1992)
    (citing Pub. Int. Rsch. Grp. of N.J., Inc. v. Powell Duffryn Terminals, Inc., 
    913 F.2d 64
    , 72
    (3d Cir. 1990)). “Proximate causation is not a requirement of Article III standing . . . .”
    Lexmark, 572 U.S. at 134 n.6.
    Even so, a plaintiff’s injury is not fairly traceable to the defendant’s action if the
    plaintiff “independently caused his own injury.” Swann v. Sec’y, Ga., 
    668 F.3d 1285
    , 1288
    (11th Cir. 2012); see also Buchholz v. Meyer Njus Tanick, PA, 
    946 F.3d 855
    , 866 (6th Cir.
    2020); cf. Pennsylvania v. New Jersey, 
    426 U.S. 660
    , 664, 667 (1976) (injuries to plaintiff-
    states were “self-inflicted” so they could not bring an original-jurisdiction suit in the
    Supreme Court). But Dr. DiCocco’s allegations—which we must take as true at this
    6
    USCA4 Appeal: 20-1342      Doc: 29         Filed: 11/17/2021      Pg: 7 of 47
    stage—do not show that she independently caused her own injuries. Dr. DiCocco’s
    complaint alleges that BOP’s ultimatum, which followed from the allegedly discriminatory
    policy, was the but-for cause of her injuries. J.A. 7 (“Dr. DiCocco was informed that unless
    she resigned, her employment with BOP would be terminated for failure to pass the [test]
    within the required times.”). Perhaps Dr. DiCocco’s choice to resign instead of retaking
    the test was a proximate cause of her injuries. But that does not defeat standing. See
    Lexmark, 572 U.S. at 134 n.6. She has alleged that her injuries were caused by BOP’s
    allegedly discriminatory policy requiring new hires to take and pass the test or be
    terminated. Without that policy, according to Dr. DiCocco, she would not have resigned.
    So on the face of the complaint, Dr. DiCocco’s alleged injuries are fairly traceable to the
    BOP’s actions.
    Finally, the Government does not dispute that Dr. DiCocco properly alleges that her
    injury will “likely” be “redressed by a favorable decision.” Lujan, 
    504 U.S. at
    561–62
    (quoting Simon, 
    426 U.S. at
    41–42). And we agree that Dr. DiCocco’s injuries would be
    redressed by an award of damages or reinstatement to her prior position.
    Because Dr. DiCocco’s complaint adequately alleges an injury in fact, causation,
    and redressability, she has standing to raise her ADEA and Title VII claims in federal court.
    Her complaint should not have been dismissed on this ground.
    B.     ADEA disparate-impact cause of action
    We continue to Dr. DiCocco’s ADEA claim. Dr. DiCocco argues that the BOP’s
    fitness test disparately impacts those older than 40. The government argues, however, that
    the ADEA provision that governs federal-government employees, 29 U.S.C. § 633a(a),
    7
    USCA4 Appeal: 20-1342       Doc: 29          Filed: 11/17/2021      Pg: 8 of 47
    does not provide for a disparate-impact cause of action. 1 Without a cause of action, Dr.
    DiCocco’s claim fails. The government continues, explaining that because the statute does
    not provide for such a claim, Congress has not waived the federal government’s sovereign
    immunity for a federal employee’s ADEA disparate-impact claim.
    Sovereign immunity is “jurisdictional in nature” because it prevents a claim from
    being brought against the sovereign. FDIC v. Meyer, 
    510 U.S. 471
    , 475 (1994); see also
    United States v. Mitchell, 
    463 U.S. 206
    , 212 (1983) (“[T]he United States may not be sued
    without its consent and . . . the existence of consent is a prerequisite for jurisdiction.”). The
    sovereign can waive its immunity by a clear statement that is “unequivocally expressed in
    statutory text.” Lane v. Peña, 
    518 U.S. 187
    , 192 (1996). Because the scope of the waiver
    determines which claims can be brought against the sovereign, “the terms of [a sovereign’s]
    consent to be sued in any court define that court’s jurisdiction to entertain the suit.” United
    1
    Disparate-impact claims address practices that have a disproportionately adverse
    effect on a certain group, even without evidence of discriminatory intent. In 1971, the
    Supreme Court interpreted the Civil Rights Act of 1964 to “prohibit, in some cases,
    employers’ facially neutral practices that, in fact, are ‘discriminatory in operation.’” Ricci
    v. DeStefano, 
    557 U.S. 557
    , 577–78 (2009) (quoting Griggs v. Duke Power Co., 
    401 U.S. 424
    , 431 (1971)). In doing so, Griggs found the “‘touchstone’ for disparate-impact
    liability” to be the lack of “business necessity”: “If an employment practice which operates
    to exclude [minorities] cannot be shown to be related to job performance, the practice is
    prohibited.” 
    Id.
     (alteration in original) (quoting Griggs, 
    401 U.S. at 431
    ). Twenty years
    after Griggs, the Civil Rights Act of 1991 codified the prohibition of disparate-impact
    discrimination on the basis of race, color, religion, sex, or national origin unless the
    employment practice was job-related and consistent with business necessity. 42 U.S.C.
    § 2000e-2(k)(1)(A)(i); see also § 2000e-2(k)(1)(A)(ii), (C) (permitting a plaintiff to
    overcome a job-related rationale if the employer refuses to adopt an available alternative
    employment practice that has less disparate impact and serves the employer’s legitimate
    needs).
    8
    USCA4 Appeal: 20-1342      Doc: 29         Filed: 11/17/2021     Pg: 9 of 47
    States v. Sherwood, 
    312 U.S. 584
    , 586 (1941). So “[j]urisdiction over any suit against the
    Government requires a clear statement from the United States waiving sovereign immunity
    together with a claim falling within the terms of the waiver.” United States v. White
    Mountain Apache Tribe, 
    537 U.S. 465
    , 472 (2003) (internal citations omitted).
    The ADEA “unequivocally” waives the government’s immunity from suit for
    claims under § 633a(a).      Gomez-Perez, 553 U.S. at 491; see 29 U.S.C. § 633a(c)
    (“Any person aggrieved may bring a civil action in any Federal district court of competent
    jurisdiction for such legal or equitable relief as will effectuate the purposes of this
    chapter.”). So we are left to determine whether Dr. DiCocco has asserted a claim that falls
    within the terms of that waiver. 2 She has not.
    The ADEA’s federal-sector provision, § 633a(a), provides: “All personnel actions
    affecting [federal] employees or applicants for [federal] employment who are at least 40
    years of age . . . shall be made free from any discrimination based on age.” 29 U.S.C.
    § 633a(a) (emphasis added). Our task is to determine whether this provision encompasses
    disparate-impact claims.
    2
    It is true that any waiver of immunity must be “‘unequivocally expressed in
    statutory text’ and ‘will be strictly construed, in terms of its scope, in favor of the
    sovereign.’” Gomez-Perez, 553 U.S. at 491 (quoting Lane, 
    518 U.S. at 192
    ). Yet Gomez-
    Perez makes clear that because § 633a(c) is the provision waiving sovereign immunity,
    only § 633a(c) must “surmount” this “high hurdle”; the substantive provision in § 633a(a)
    need not. Id.
    9
    USCA4 Appeal: 20-1342       Doc: 29          Filed: 11/17/2021      Pg: 10 of 47
    In doing so, we are guided by the Supreme Court’s interpretation of similar
    provisions. See Smith v. City of Jackson, 
    544 U.S. 228
    , 234–40 (2005) (plurality opinion); 3
    Gomez-Perez, 
    553 U.S. 474
    . Considering the framework provided by these two cases, we
    conclude that the language of § 633a(a) does not create a disparate-impact cause of action.
    In Smith, a plurality of the Supreme Court held that “the ‘disparate-impact’ theory
    of recovery announced in Griggs v. Duke Power Co., 
    401 U.S. 424
     (1971), for cases
    brought under Title VII of the Civil Rights Act of 1964, is cognizable under” § 623(a)(2),
    the section of the ADEA that addresses private-sector conduct. Smith, 
    544 U.S. at 230
    ,
    233–40 (plurality opinion). In so holding, the plurality relied on four arguments: statutory
    text, statutory structure, precedent, and deference to agency action. 
    Id.
    First, the text of the ADEA’s private-sector provision, § 623(a)(2): It “shall be
    unlawful for an employer . . . to limit, segregate, or classify his employees in any way
    which would deprive or tend to deprive any individual of employment opportunities or
    otherwise adversely affect his status as an employee, because of such individual’s age.”
    This text uses the same language, swapping the term “race” for “age,” as § 703(a)(2) of
    Title VII, which Griggs found to encompass disparate-impact liability. Smith, 
    544 U.S. at
    3
    While Sections I, II, and IV of Smith are the opinion of the Court, Section III—
    which discusses disparate-impact liability—was not joined by Justice Scalia and is
    therefore only a plurality opinion. Smith, 
    544 U.S. at 229
    . Despite not joining that Section,
    Justice Scalia stated that he “agree[d] with all of the Court’s reasoning,” finding it a
    compelling basis for deferring to the Equal Employment Opportunity Commission’s
    similar interpretation. 
    Id. at 243
     (Scalia, J., concurring in part). The Court has since treated
    the plurality’s opinion as essentially controlling. See Meacham v. Knolls Atomic Power
    Lab’y, 
    554 U.S. 84
    , 95–96 (2008).
    10
    USCA4 Appeal: 20-1342       Doc: 29           Filed: 11/17/2021    Pg: 11 of 47
    233–34 (plurality opinion). As the ADEA used language derived from Title VII, the
    plurality presumed the two had the same meaning. So Griggs “strongly suggest[ed] that a
    disparate-impact theory” should also be cognizable under the ADEA’s private-sector
    provision, § 623(a)(2). Id. at 236.
    But Smith did not rely exclusively on the precedential value of Griggs. It went on
    to explain why, in its view, Griggs articulated the “better reading of the statutory text.” Id.
    at 235. Disparate-impact liability fit the language of Title VII’s private-sector provision
    (and therefore the comparable ADEA provision) because those provisions “focus[] on the
    effects of the action on the employee rather than the motivation for the action of the
    employer.” Id. at 235–36 (emphasis added); see also id. at 234 (noting Title VII was
    directed at the consequences of the employer’s action, not just the employer’s motivation). 4
    In contrast, disparate-impact liability was excluded where the ADEA’s statutory language
    focused “on the employer’s actions with respect to the targeted individual.” Id. at 236 n.6. 5
    4
    The private-sector Title VII provision provides: “It shall be an unlawful
    employment practice for an employer . . . to limit, segregate, or classify his employees or
    applicants for employment in any way which would deprive or tend to deprive any
    individual of employment opportunities or otherwise adversely affect his status as an
    employee, because of such individual’s race, color, religion, sex, or national origin.” 42
    U.S.C. § 2000e-2(a)(2).
    5
    As an example of statutory language focused on the employer’s actions and not
    the impact on the employee, Smith noted another subsection of the ADEA, § 623(a)(1),
    which makes it “unlawful for an employer . . . to fail or refuse to hire or to discharge any
    individual or otherwise discriminate against any individual with respect to his
    compensation, terms, conditions, or privileges of employment, because of such
    individual’s age.” 
    29 U.S.C. § 623

    Second, Smith relied on statutory structure, especially the existence of a statutory
    defense for “reasonable factors other than age,” to support finding disparate-impact
    liability in the private-sector provision. 
    Id.
     at 238–39. The defense permits an employer
    to “take any action otherwise prohibited [by the private-sector provision] . . . where the
    differentiation is based on reasonable factors other than age.” 
    29 U.S.C. § 623
    (f)(1). This
    provision “plays its principal role,” Smith explained, in disparate-impact cases “by
    precluding liability if the adverse impact was attributable to a nonage factor that was
    ‘reasonable.’” Smith, 
    544 U.S. at 239
     (plurality opinion). So its presence was probative
    of the statute’s intended scope.
    Finally, the Court noted that the Department of Labor, which drafted the legislation,
    and the Equal Employment Opportunity Commission, which was delegated the
    responsibility of enforcing the statute, had consistently interpreted the ADEA’s private-
    sector provision to encompass disparate-impact liability. Id.; see also 
    id. at 243
     (Scalia, J.,
    concurring) (characterizing this as Chevron deference).
    Smith thus relied on text, structure, precedent, and agency guidance to find that the
    ADEA’s private-sector provision authorizes a disparate-impact cause of action.
    Three years after Smith, the Court again returned to interpret the ADEA. This time,
    the Court addressed the federal-sector provision of the ADEA, holding that the term
    “discrimination based on age” in the ADEA’s federal-sector provision includes retaliation
    claims. Gomez-Perez, 
    553 U.S. at 479
    . To do so, the Court turned to precedent interpreting
    statutory language that was “not materially different” from the ADEA provision and that
    carried the same context: “remedial provisions aimed at prohibiting discrimination.” 
    Id.
    12
    USCA4 Appeal: 20-1342       Doc: 29          Filed: 11/17/2021      Pg: 13 of 47
    at 481. The first case, Sullivan v. Little Hunting Park, Inc., 
    396 U.S. 229
     (1969), held that
    retaliation claims could be brought under 
    42 U.S.C. § 1982
    . 6 Gomez-Perez, 
    553 U.S. at 479
    . While that provision did not explicitly “use the phrase ‘discrimination based on
    race,’” the Court found that to be the statute’s plain meaning. 
    Id.
     The second case, Jackson
    v. Birmingham Board of Education, 
    544 U.S. 167
     (2005), relied on Sullivan’s interpretation
    of § 1982 to interpret 
    20 U.S.C. § 1681
    (a), 7 part of Title IX, to prohibit retaliation. Gomez-
    Perez, 
    553 U.S. at 480
    . Jackson had “presume[d] that Congress was thoroughly familiar
    with [Sullivan]” and expected Title IX “to be interpreted in conformity with [it].” 
    Id. at 485
     (alteration in original) (quoting Jackson, 544 U.S. at 176). 8
    Gomez-Perez followed “the reasoning of Sullivan and Jackson” to “interpret the
    ADEA federal-sector provision’s prohibition of ‘discrimination based on age’” to likewise
    prohibit retaliation. Id. at 481. In doing so, the Court explained that “retaliation is
    discrimination ‘on the basis of [a protected class]’ because it is an intentional response to
    the nature of the complaint: an allegation of . . . discrimination [against that class].” Id. at
    480 (emphasis added) (quoting Jackson, 544 U.S. at 173–74).

    “All citizens of the United States shall have the same right, in every State and
    Territory, as is enjoyed by white citizens thereof to inherit, purchase, lease, sell, hold, and
    convey real and personal property.”

    “No person in the United States shall, on the basis of sex, be excluded from
    participation in, be denied the benefits of, or be subjected to discrimination under any

    20 U.S.C. § 1681
    (a).
    8
    The ADEA’s federal-sector provision was enacted in 1974, five years after
    Sullivan and two years after the enactment of Title IX. 
    Id. at 485
    .
    13
    USCA4 Appeal: 20-1342         Doc: 29         Filed: 11/17/2021     Pg: 14 of 47
    The Court observed that the ADEA’s federal-sector provision differed sharply from
    the private-sector provision. The federal-sector provision includes “a broad prohibition of
    ‘discrimination,’” while the ADEA’s private-sector provision includes “a list of specific
    prohibited practices.” 
    Id. at 487
    . So the Court found that the enactment of a broad ban,
    like Title VII’s ban interpreted in Griggs and Title VI’s ban interpreted in Sullivan,
    suggested Congress expected it to “be interpreted ‘in conformity’ with” Sullivan to include
    retaliation claims. 
    Id. at 488
     (citations omitted). The express inclusion of retaliation in the
    private-sector provision but not in the federal-sector provision lacks significance given the
    breadth of the prohibition and its similarity to the other broad bans. 
    Id.
    Gomez-Perez thus relied on the statute’s text and the legal landscape in which it was
    enacted to find that the ADEA’s public-sector provision authorizes a retaliation cause of
    action.
    Dr. DiCocco urges us to read these two cases to find that the ADEA’s federal-sector
    provision should also encompass disparate-impact liability. See Lujan v. Walters, 
    813 F.2d 1051
    , 1057–58 (10th Cir. 1987) (analyzing a disparate-impact claim under the federal-
    sector provision without explaining why a disparate-impact claim is permitted); Palmer v.
    United States, 
    794 F.2d 534
    , 536–37 (9th Cir. 1986) (same). But the arguments that emerge
    from Smith and Gomez-Perez—those based on the statute’s text, the law’s structure, and
    the legal landscape in which the law was passed—do not support such a finding here. 9
    Neither party cites guidance from the Equal Employment Opportunity
    9
    Commission that considers whether the federal-sector provision encompasses disparate-
    impact liability. But see Kennedy v. McDonald, No. 3:15-1844-MBS-KDW, 2016 WL

    Start with the text. See Barnhart v. Sigmon Coal Co., 
    534 U.S. 438
    , 450 (2002).
    Section 633a(a) provides: “All personnel actions affecting employees or applicants for
    employment who are at least 40 years of age . . . shall be made free from any discrimination
    based on age.”
    Smith teaches that statutes barring disparate treatment focus on the “motivation for
    the action of the employer.” 544 U.S. at 235–36. Only where the statutory prohibition
    refers to the “consequences of actions and not just to the mindset of actors” is disparate-
    impact liability authorized. Tex. Dep’t of Hous. & Cmty. Affairs v. Inclusive Cmtys.
    Project, Inc., 
    135 S. Ct. 2507
    , 2518 (2015); see also Smith, 
    544 U.S. at
    235–36. The
    ADEA’s federal-sector provision addresses the actor’s intent: “personnel actions affecting
    employees or applicants for employment . . . shall be made free from any discrimination
    based on age.” 29 U.S.C. § 633a(a) (emphasis added). “The phrase ‘free from any

    2017 WL 1162978
     (D.S.C. Mar. 29, 2017) (referencing an Informal Discussion Letter
    through an out-of-date hyperlink that purportedly states that “the [Equal Employment
    Opportunity Commission] has long held that disparate impact claims are available under
    § 633a”). Contrary to the dissent’s position, nothing in 
    29 C.F.R. § 1614.103
    (c) authorizes
    disparate-impact claims. That regulation merely identifies the broad scope of covered
    employment decisions. See 
    29 C.F.R. § 1614.103
    (c) (“Within the covered departments,
    agencies and units, this part applies to all employees and applicants for employment, and
    to all employment policies or practices affecting employees or applicants for employment
    including employees and applicants who are paid from nonappropriated funds, unless
    otherwise excluded.”). At most, we have located a few Equal Employment Opportunity
    Commission appeals that appear to recognize disparate-impact claims under the federal-
    sector provision. See Carpenter v. Peters, EEOC DOC 0120065151, 
    2007 WL 632984
    , at
    *2 (EEOC Feb. 23, 2007); Witkowsky v. Babbitt, EEOC DOC 03970122, 
    1998 WL 563824
    ,
    at *3 (EEOC Jan. 30, 1998). So this consideration from Smith does little to help Dr.
    DiCocco.

    discrimination’ is an adverbial phrase that modifies the verb ‘made.’” Babb v. Wilkie, 
    140 S. Ct. 1168
    , 1173 (2020). So it “describes how a personnel action must be ‘made.’” 
    Id. at 1174
    . Thus, the statutory text asks if “age discrimination plays any part in the way a
    decision is made.” 
    Id.
     That focus on the “motivation for the employer’s action”—and not
    the “effects of the action on the employee”—precludes disparate-impact liability under
    Smith. 
    544 U.S. at
    235–36 & n.6.
    Recall that, unlike § 633a(a), the Title VII text interpreted in Smith prohibits
    classifications “which would deprive or tend to deprive any individual of employment
    opportunities or otherwise adversely affect his status as an employee, because of such
    individual’s age.” § 623(a)(2) (emphasis added). That language directs our focus to the
    consequences of an action on the employee and thus permits disparate-impact liability. But
    the text of § 633a(a) directs our focus to the actor’s intent and whether it involved
    discrimination. 10 And that focus on the actor’s intent precludes disparate-impact liability.
    10
    As the dissent notes, § 633a(a) does contain the word “affecting.” But it uses it
    in a different way than § 623(a)(2). It is not the mere presence of the word “affects” that
    creates disparate-impact liability in § 623(a)(2); it’s how it’s used. In § 633a(a) the phrase
    “affecting employees” is an adjectival phrase modifying “all personnel actions.” It
    describes the types of actions covered by the statutory prohibition. In contrast, § 623(a)(2)
    uses “affect” as the verb describing the impact of the age-based classification. So the clause
    “because of age” modifies “affects,” thus reaching age-based effects of neutral employer
    actions. See Smith, 
    544 U.S. at
    236 n.6 (noting that the language creates “an incongruity
    between” the employer’s action and the employee’s harm, such that “an employer who
    classifies his employees without respect to age may still be liable . . . if such classification
    adversely affects the employee because of that employee’s age—the very definition of
    disparate impact.” (emphasis added)). But in § 633a(a), “because of age” does not modify
    “affecting” but rather “discrimination” (i.e., differential treatment), which must not be
    allowed to taint the employer’s “actions.” The difference goes to the heart of the difference
    (Continued)
    16
    USCA4 Appeal: 20-1342       Doc: 29          Filed: 11/17/2021      Pg: 17 of 47
    The Supreme Court’s analysis of § 633a(a) in Babb reinforces this conclusion.
    While Babb did not concern the existence of disparate-impact liability specifically, the
    Supreme Court did interpret the words of the statute, and that interpretation forecloses
    disparate-impact liability.
    Babb explained that the term “personnel actions” includes “most employment-
    related decisions” and that § 633a(a) protects against decisions in which “age
    discrimination plays any part in the way a decision is made.” 140 S. Ct. at 1173–74
    (emphasis added). So, under Babb’s interpretation, the text of § 633a(a) looks to the
    motivation behind, rather than the effect of, the decision. Id. at 1173–74 (“Thus, ‘free from
    any discrimination’ describes how a personnel action must be ‘made,’ namely, in a way
    that is not tainted by differential treatment based on age. If age discrimination plays any
    part in the way a decision is made, then the decision is not made in a way that is untainted
    by such discrimination.”). And yet the Supreme Court directs that disparate-impact
    liability applies only when the text focuses on the consequences of a decision, not on the
    actor’s intent. Cf. Tex. Dep’t of Hous. & Cmty. Affairs, 576 U.S. at 534 (“the consequences
    of an action rather than the actor’s intent”); Bd. of Educ. of City Sch. Dist. of N.Y. v. Harris,
    
    444 U.S. 130
    , 140–41 (1979) (same); see also Smith, 
    544 U.S. at
    235–36 & n.6. 11
    between disparate-impact and disparate-treatment: whether we look to age-based effects or
    age-based discrimination.
    11
    To the extent that the ADEA’s federal-sector provision mirrors any part of the
    private-sector provision, see Gomez-Perez, 
    553 U.S. at
    486–87, it more closely resembles
    § 623(a)(1), which focuses on the employer’s actions and thus does not encompass
    disparate-impact liability, Smith, 
    544 U.S. at
    236 n.6, than § 623(a)(2), which focuses on
    (Continued)

    USCA4 Appeal: 20-1342      Doc: 29         Filed: 11/17/2021      Pg: 18 of 47
    Having established that the statute places a condition on an employer’s decisions,
    the rest of the statute establishes what that condition is: Those decisions “shall be made
    free from any discrimination based on age.” If age-based animus even slightly “tainted”
    the employer’s decision, then that decision was not “made free from any” age-based
    discrimination. 140 S. Ct. at 1173–74. 12
    The Babb Court read “discrimination” to “carr[y] its ‘normal definition,’ which is
    ‘differential treatment.’” Id. at 1173. So under § 633a(a), the Court concluded, “age must
    be a but-for cause of discrimination—that is, of differential treatment.” Id. “Differential
    treatment” directs the statute’s focus to the employer’s action, not the consequences of the
    the effect on the employee and thus encompasses disparate-impact liability, id. at 235–36.
    Compare § 633a(a) (“All personnel actions affecting [federal] employees or applicants for
    [federal] employment who are at least 40 years of age . . . shall be made free from any
    discrimination based on age.” (emphasis added)), with 
    29 U.S.C. § 623
    (a)(1) (“It shall be
    unlawful for an employer . . . to fail or refuse to hire or to discharge any individual or
    otherwise discriminate against any individual with respect to his compensation, terms,
    conditions, or privileges of employment, because of such individual’s age.” (emphasis
    added)), and § 623(a)(2) (“It shall be unlawful for an employer . . . to limit, segregate, or
    classify his employees in any way which would deprive or tend to deprive any individual
    of employment opportunities or otherwise adversely affect his status as an employee,
    because of such individual’s age.” (emphasis added)).
    12
    The dissent stresses the word “any,” taking it to mean “‘one or another taken at
    random’ or ‘selected without restriction,’” and postulates that it shows Congressional
    intent to reach multiple types of “discrimination.” See Dissent at 6. But Babb applied a
    different “standard dictionary definition” of “any” in this context: “[s]ome, regardless of
    quantity or number.” 140 S. Ct. at 1173 n.2 (quoting American Heritage Dictionary 59
    (def. 2) (1969)). So “any” is being used as a quantitative description of the amount of
    discrimination permitted (i.e., none). Under the Supreme Court’s definition, the clause is
    equivalent to “free from any amount of discrimination,” not “free from any type of
    discrimination,” and so does not, as the dissent suggests, expand what qualifies as
    “discrimination” beyond its plain meaning—“differential treatment.”
    18
    USCA4 Appeal: 20-1342        Doc: 29          Filed: 11/17/2021     Pg: 19 of 47
    action on the employee, and requires intent. See Jackson v. Birmingham Bd. of Educ., 
    544 U.S. 167
    , 175 (2005) (“‘Discrimination’ is a term that covers a wide range of intentional
    unequal treatment.”); see also Puffer v. Allstate Ins., 
    675 F.3d 709
    , 716 (7th Cir. 2012).
    And disparate-impact liability is not a form of intentional discrimination or differential
    treatment. See Ricci v. DeStefano, 
    557 U.S. 557
    , 577 (2009) (contrasting “intentional
    discrimination (known as ‘disparate treatment’)” with “practices that are not intended to
    discriminate but in fact have a disproportionately adverse effect on minorities (known as
    ‘disparate impact’)”).
    Finally, the statute identifies which type of intentional differential treatment is not
    allowed: that which is “based on age.” As Babb declares and our colleague in dissent
    acknowledges, this clause requires that age “be a but-for cause of discrimination—that is,
    of differential treatment.” 140 S. Ct. at 1173; see also Dissent at 6. So, § 633a(a) is only
    implicated where an employer intended to treat otherwise identical employees differently
    because of their ages.
    So in sum, the text of § 633a(a) requires that employment-related decisions be
    untainted by differential treatment of employees identical in all respects but age. This
    standard authorizes disparate-treatment claims, such as where an employer’s age-based
    animus contributes to their decision to pass over an employee for promotion. See, e.g.,
    Babb, 
    140 S. Ct. 1168
    . But it does not encompass disparate-impact claims, where an
    employer adopts a policy that treats all employees the same, no matter how old they happen
    to be.

    USCA4 Appeal: 20-1342      Doc: 29         Filed: 11/17/2021      Pg: 20 of 47
    The statutory structure also supports this conclusion. Smith relied on the narrowing
    effect of the reasonable-factors defense to justify finding disparate-impact liability under
    the private-sector provision. 544 U.S. at 239 (plurality opinion). The Court noted that the
    defense reflected Congress’s understanding that age often “has relevance to an individual’s
    capacity to engage in certain types of employment.” Id. at 240–41. So Congress would
    not prohibit every potential disparate impact based on age without providing a defense to
    protect legitimate actions. Id.; see also Meacham v. Knolls Atomic Power Lab’y, 
    554 U.S. 84
    , 97 (2008) (holding that the ADEA private-sector provision does not include a business-
    necessity defense but relies solely on the reasonable-factors defense). Smith reasoned that
    Congress’s inclusion of the reasonable-factors defense as a limit reflects the intention to
    sweep broadly and include disparate-impact claims. Smith, 544 U.S. at 239 (plurality
    opinion).
    Title VII’s federal-sector provision also expressly incorporates a defense to
    disparate-impact claims—specifically, a business-necessity defense. See 42 § 2000e-
    2(k)(1)(A)(i) (including as part of the burden that the “respondent” can “demonstrate that
    the challenged practice is job-related for the position in question and consistent with
    business necessity”); § 2000e(n) (defining “respondent” in § 2000e-2(k) to include federal
    employers); Rodriguez v. United States, 
    852 F.3d 67
    , 77–78 (1st Cir. 2017) (explaining
    how the federal-sector provision is the same as the private-sector provision under Title VII,
    including disparate-impact); Phillips v. Cohen, 
    400 F.3d 388
    , 397–98 (6th Cir. 2005)
    (noting the business-necessity defense when applying § 2000e-2(k)(1)(A) to a federal
    employee); Figueroa v. Pompeo, 
    923 F.3d 1078
    , 1083–85 (D.C. Cir. 2019) (same).

    USCA4 Appeal: 20-1342      Doc: 29          Filed: 11/17/2021     Pg: 21 of 47
    Unlike a Title VII disparate-impact claim or a private-sector ADEA claim, however,
    the ADEA’s federal-sector provision provides no business-necessity defense nor
    reasonable-factor defense. 13 Indeed, it contains no defense at all. Using Smith’s logic, the
    absence of the limiting defenses found in comparable provisions suggests that Congress
    did not intend to include a broad disparate-impact claim in the ADEA’s federal-sector
    provision.
    Dr. DiCocco finally points to the legal landscape to suggest that we should read the
    federal-sector provision as encompassing a disparate-impact cause of action. As the
    Supreme Court has recognized, the federal-sector provision was “patterned ‘directly after’
    Title VII’s federal-sector discrimination ban.” Gomez-Perez, 
    553 U.S. at 487
     (quoting
    Lehman v. Nakshian, 
    453 U.S. 156
    , 167 n.15 (1981)). The Title VII provision expressly
    prohibits discrimination based on disparate impact. See 42 U.S.C. § 2000e-2(k) (codifying
    the burden of proof for disparate-impact cases against “respondent[s]”); § 2000e(n)
    (defining “respondent” in § 2000e-2(k) to include federal employers). And the Supreme
    Court has separately held that the ADEA’s private-sector provision, in part, provides for
    disparate-impact liability. Smith, 
    544 U.S. at 240
     (plurality opinion). But the legal
    landscape when the federal-sector provision was passed does not suggest that Congress
    intended the ADEA’s federal-sector provision to include disparate-impact liability.
    13
    The reasonable-factors defense, 
    29 U.S.C. § 623
    (f)(1), does not apply to cases
    brought under the federal-sector provision. See 29 U.S.C. § 633a(f) (“Any personnel action
    of any department, agency, or other entity referred to in subsection (a) of this section shall
    not be subject to, or affected by, any provision of this chapter, other than the provisions of
    sections 626(d)(3) and 631(b) of this title and the provisions of this section.”).
    21
    USCA4 Appeal: 20-1342       Doc: 29        Filed: 11/17/2021     Pg: 22 of 47
    The ADEA’s federal-sector provision was enacted in 1974, long before the 1991
    amendments to Title VII codified disparate-impact liability for federal employers. Before
    those amendments, the Supreme Court had not considered whether Title VII’s federal-
    sector provision permitted disparate-impact claims. Cf. Griggs, 
    401 U.S. at
    426 n.1, 429–
    30 (explaining, in 1971, that the private-sector provisions of Title VII permit disparate-
    impact claims). The amendments “expanded the coverage of Title VII” to disparate-impact
    liability but did not make corresponding changes to the ADEA. Smith, 
    544 U.S. at 240
    .
    So because the Title VII amendments resolved the federal-sector disparate-impact question
    after the ADEA’s federal-sector provision was enacted, we do not see how Congress could
    have incorporated their substance into the ADEA, especially when it expressly included
    disparate-impact language in Title VII but left the ADEA unaltered. See Gross v. FBL Fin.
    Servs., Inc., 
    557 U.S. 167
    , 174 (2009) (“We cannot ignore Congress’ decision to amend
    Title VII’s relevant provisions but not make similar changes to the ADEA. When Congress
    amends one statutory provision but not another, it is presumed to have acted
    intentionally.”).
    To be sure, Griggs, which interpreted Title VII’s private-sector provision to include
    disparate-impact liability, was decided three years before the ADEA federal-sector
    provision was enacted. But Title VII’s private-sector provision is worded and structured
    differently than the ADEA’s federal-sector provision. See Gomez-Perez, 
    553 U.S. at 474
    (explaining that the language of § 633a(a) differs sharply from the language of § 623(a),
    which, as the Supreme Court explained in Smith, 
    554 U.S. at 236
    , is nearly identical to that
    of Title VII’s private-sector provision). Compare 42 U.S.C. § 2000e-2(a) (Title VII
    22
    USCA4 Appeal: 20-1342      Doc: 29          Filed: 11/17/2021        Pg: 23 of 47
    private-sector provision), with 29 U.S.C. § 633a(a) (ADEA federal-sector provision). So
    Congress would not have had a “reason to expect” that the ADEA’s federal-sector
    provision “would be interpreted ‘in conformity’ with” Griggs. Gomez-Perez, 
    553 U.S. at 488
     (quoting Jackson, 544 U.S. at 176). So even though a Title VII disparate-impact case
    would normally be a “compelling” precedent in interpreting the ADEA, Smith, 
    544 U.S. at 234
    , Griggs does not control here. 14
    In conclusion, neither the legal background at enactment nor the statute’s text and
    structure support allowing a disparate-impact liability claim under the federal-sector
    provision of the ADEA. So we hold that Dr. DiCocco’s disparate-impact claim is not
    cognizable under the ADEA’s federal-sector provision. And because the government’s
    waiver of sovereign immunity is limited to claims by persons “aggrieved” under the
    section, her claim is not within the scope of that waiver.
    14
    The dissent insists that we are bound by two pre-1991 cases in which the Fourth
    Circuit permitted Title VII disparate-impact claims against the federal government. See
    Dissent at 16. But neither decision analyzes whether the text of 42 U.S.C. § 2000e-16(a)
    permits disparate impact claims. See Wright v. Nat’l Archives & Records Serv., 
    609 F.2d 702
     (4th Cir. 1979) (en banc); Chisholm v. U.S. Postal Serv., 
    665 F.2d 482
     (4th Cir. 1981).
    Instead, they simply assume that the claims are permitted. See Wright, 
    609 F.2d at 711
    (assuming private-sector precedent applied without acknowledging differences between
    the private-sector and government provisions); Chisholm, 
    665 F.2d at 497
     (assuming,
    without discussion, that both disparate-impact and disparate-treatment claims were
    available). And assumptions—particularly those that are unaddressed, concern a different
    statute, and conflict with subsequent Supreme Court decisions like Smith, Texas
    Department of Housing and Community Affairs, and Babb—are not holdings. See Webster
    v. Fall, 
    266 U.S. 507
    , 511 (1925) (“Questions which merely lurk in the record, neither
    brought to the attention of the court nor ruled upon, are not to be considered as having been
    so decided as to constitute precedents.”); see also Mays v. Sprinkle, 
    992 F.3d 295
    , 302 n.4
    (4th Cir. 2021).

    The district court erred in dismissing Dr. DiCocco’s complaint for lack of standing
    based on its analysis of the merits of her claim. She has sufficiently pleaded facts showing
    that she has Article III standing to raise her claims in federal court, even if those claims do
    not prevail on the merits. But the dismissal of her ADEA claim must be affirmed because
    the government’s waiver of sovereign immunity does not cover disparate-impact claims.
    Though the government asks that we address the merits of her Title VII disparate-impact
    claim on appeal, we remand that claim for consideration first by the district court. 15
    Accordingly, the district court’s judgment is
    AFFIRMED IN PART,
    REVERSED IN PART,
    AND REMANDED.
    15
    The government contends that her Title VII claim fails because she cannot show
    an adverse employment action. Cf. Aliotta v. Bair, 
    614 F.3d 556
    , 566 (D.C. Cir. 2010)
    (“Under either a disparate treatment or disparate impact theory of discrimination, plaintiffs
    must show they suffered an adverse employment action.”). Though Dr. DiCocco does not
    contest that a Title VII disparate-impact claim requires an adverse employment action, we
    decline to address that threshold question, which appears to be unanswered in our circuit
    and underdeveloped in other circuits.
    24

    FLOYD, Circuit Judge, concurring in part and dissenting in part:
    I agree with the majority that Dr. Jane DiCocco possesses Article III standing to
    bring her disparate-impact claims under the Age Discrimination in Employment Act of
    1967 (ADEA) and Title VII of the Civil Rights Act of 1964 (Title VII). I concur with Parts
    I and II.A of the majority’s opinion, and I also concur with the majority’s decision to
    remand Dr. DiCocco’s disparate-impact claim under Title VII for substantive findings in
    the first instance. But rather than similarly remanding Dr. DiCocco’s disparate-impact
    claim under the ADEA for findings in the first instance, the majority reaches its own
    debatable holding. Diverging from our sister circuits and overruling our prior precedents,
    the majority holds that the ADEA does not afford a disparate-impact cause of action for
    federal employees. In my view, the ADEA does not tolerate this holding under the
    traditional tools of statutory interpretation and our precedents. Therefore, I respectfully
    dissent with respect to Part II.B of the majority’s opinion.
    I.
    Because Dr. DiCocco has standing to bring her suit, the first issue before the Court
    is whether the ADEA’s federal-sector ban on age discrimination provides a cause of action
    for disparate-impact claims and whether the scope of the federal government’s waiver of
    sovereign immunity includes such claims. Based upon the text of the ADEA, its history
    and structure, and Supreme Court precedent, I would hold that the ADEA permits
    disparate-impact claims against the federal government, and that the federal government
    has waived its sovereign immunity.

    “[A] waiver of sovereign immunity must be ‘unequivocally expressed’ in statutory

    also Lane v. Peña, 
    518 U.S. 187
    , 192 (1996). If a statute’s language contains ambiguities,
    those ambiguities must be construed in favor of sovereign immunity “so that the
    Government’s consent to be sued is never enlarged beyond what a fair reading of the text
    requires . . . .” Cooper, 
    566 U.S. at 290
     (internal citation omitted). When the scope of a
    waiver is at issue, statutory ambiguities are also construed in favor of the sovereign. 
    Id. at 291
    . Congress need not use “magic words” to waive the federal government’s sovereign
    immunity. 
    Id.
     The only requirement is that “the scope of Congress’ waiver be clearly
    discernable from the statutory text in light of traditional interpretive tools.” 
    Id.
     Our tools
    for statutory interpretation include: (1) statutory text; (2) statutory structure; (3) legislative
    history; (4) judicial interpretations; (5) related statutes; and (6) congressional purpose. See
    Brown & Williamson Tobacco Corp. v. Food & Drug Admin., 
    153 F.3d 155
    , 162 (4th Cir.
    1998); United States v. Jackson, 
    759 F.2d 342
    , 344 (4th Cir. 1985); see also United States
    v. Bryant, 
    949 F.3d 168
    , 174–75 (4th Cir. 2020). Deploying this arsenal, I first consider
    the types of claims within employment discrimination cases and then turn to the language,
    legislative history, related statutes, and judicial interpretations implicating the ADEA’s
    federal-sector ban on age discrimination.
    A.
    In order to consider the import of the ADEA’s statutory text, we must be familiar
    with the two distinct claims in employment discrimination law: disparate-treatment and
    26
    USCA4 Appeal: 20-1342       Doc: 29         Filed: 11/17/2021      Pg: 27 of 47
    disparate-impact claims. A disparate-treatment claim arises “where an employer has
    ‘treated [a] particular person less favorably than others because of’ a protected trait.” Ricci
    v. DeStefano, 
    557 U.S. 557
    , 577 (2009) (quoting Watson v. Fort Worth Bank & Tr., 
    487 U.S. 977
    , 985–86 (1988)). If a claimant brings a disparate-treatment claim, they must
    establish that an employer possessed a “discriminatory intent or motive” for an adverse
    employment action. 
    Id.
     Disparate-impact claims seek to remove “artificial, arbitrary, and
    unnecessary barriers to employment when the barriers operate invidiously to
    discriminate . . . .” Griggs v. Duke Power Co., 
    401 U.S. 424
    , 431 (1971). Essentially,
    disparate-impact claims attack “[employment] practices that are fair in form, but
    discriminatory in operation.” Id.; see also Bauer v. Lynch, 
    812 F.3d 340
    , 349 n.10 (4th
    Cir. 2016) (“[D]isparate impact discrimination occurs when a facially neutral employment
    practice has a significantly discriminatory effect.” (citing Griggs, 
    401 U.S. at 430
    )).
    Importantly, both claims are types of discrimination, but the former involves “intentional”
    discrimination, while the latter typically involves “unintentional” discrimination. See
    Ricci, 
    557 U.S. at 577
    ; see also Raytheon Co. v. Hernandez, 
    540 U.S. 44
    , 52 (2003); Hazen
    Paper Co. v. Biggins, 
    507 U.S. 604
    , 609 (1993); N.A.A.C.P v. N. Hudson Reg’l Fire &
    Rescue, 
    665 F.3d 464
    , 482 n.11 (3d Cir. 2011). Our precedents have recognized that these
    claims are both about and stem from one thing: discrimination. See Burwell v. E. Air Lines,
    Inc., 
    633 F.2d 361
    , 369 (4th Cir. 1980). To determine whether disparate-impact claims are
    27
    USCA4 Appeal: 20-1342       Doc: 29          Filed: 11/17/2021      Pg: 28 of 47
    cognizable under ADEA’s federal-sector ban on age discrimination, I turn to the text of the
    statute.
    When prohibiting age discrimination within the federal government’s workforce,
    the ADEA declares: “All personnel actions affecting employees . . . who are at least 40
    years of age . . . shall be made free from any discrimination based on age.”                  29
    U.S.C. § 633a(a) (emphasis added). This language is unquestionably broad. In terms of
    coverage, it first applies to “all personnel actions affecting employees . . . .” Id. The statute
    uses “all” to describe “personnel actions.” See id. When used as adjective to describe a
    noun, “all” means “the whole amount, quantity, or extent of”; “every member or individual
    component of”; and “every.”              All, MERRIAM-WEBSTER, https://www.merriam-
    webster.com/dictionary/all (last visited Sept. 8, 2021). Although the ADEA does not
    define “personnel actions,” the Supreme Court borrowed the term’s definition from the
    Civil Service Reform Act of 1978 (CSA), a different statute governing federal
    employment. Babb v. Wilkie, 
    140 S. Ct. 1168
    , 1172–73 (2020). In doing so, the Court
    noted that the CSA “broadly defines a ‘personnel action’ to include most employment-
    related decisions, such as appointment, promotion, work assignment, compensation, and
    performance reviews.” 
    Id.
     at 1173 (citing 5 § U.S.C. 2302(a)(2)(A)). As a participle, 1
    “affecting” means “[acting] upon (a person or a person’s feelings) so as to cause a
    response” or “[being] the business or affair of.” Affecting, MERRIAM-WEBSTER,
    1
    A participle is a verb functioning as an adjective. Participle, Merriam-Webster,
    https://www.merriam-webster.com/dictionary/participle (last visited Oct. 19, 2021).
    28
    USCA4 Appeal: 20-1342       Doc: 29        Filed: 11/17/2021   Pg: 29 of 47
    https://www.merriam-webster.com/thesaurus/affecting (last visited Sept. 8, 2021). Thus,
    when reading these definitions together, § 633a(a) covers “every” employment-related
    decision that “act[s] upon” an employee or concerns an employee’s “affairs.” But the
    textual inquiry must go further.
    Given § 633a(a)’s expansive reach, it is imperative to consider what the statute
    protects federal employees against and when liability attaches to the federal government.
    “Under § 633a(a), personnel actions must be made ‘free from’ discrimination.” Babb, 140
    S. Ct. at 1173. The Supreme Court stated that “free from” requires personnel actions be
    “untainted” by “any discrimination.” Id. “Any” requires an “expansive meaning” and is
    defined as “[s]ome, regardless of quantity or number.” Id. at 1173 n.2 (emphasis added)
    (citations omitted). It also means “one or some indiscriminately of whatever kind,”
    indicating “one or another taken at random” or “one selected without restriction.” Any,
    MERRIAM-WEBSTER                (emphasis         added),           https://www.merriam-
    webster.com/thesaurus/affecting (last visited Sept. 10, 2021). “Discrimination” means
    “differential treatment.” Babb, 140 S. Ct. at 1173 (quoting Jackson v. Birmingham Bd. of
    Educ., 
    544 U.S. 167
    , 174 (2005)). And lastly, “shall be made” imposes an affirmative duty
    on the federal government, requiring that personnel decisions are made without a “taint”
    of discrimination. 
    Id.
     Accordingly, “every” employment-related decision by the federal
    government must be untainted by “any” differential treatment “based on age.”          
    Id.
    (emphasis added).
    In Babb v. Wilkie, the Court construed § 633a(a)’s terms to solidify the causal
    requirement, which imposes liability on the federal government for disparate-treatment
    29
    USCA4 Appeal: 20-1342       Doc: 29          Filed: 11/17/2021      Pg: 30 of 47
    claims. Id. at 1171. It emphasized that a close reading of the statutory text, including the
    relationship between the codified words, is what matters. Id. at 1173–74. Examining the
    text, the Court first reasoned “age must be a but-for cause of discrimination” because the
    phrase “based on age” modified the noun “discrimination.” Id. at 1173. It then found “free
    from discrimination” was a phrase modifying the verb “made,” thereby requiring personnel
    decisions be “untainted” by “differential treatment based on age.”             Id. at 1173–74.
    Although age must be a but-for cause of the discrimination alleged, Babb held that a
    claimant need not ultimately prove “but-for cause” to impose liability on a federal
    employer under § 633a(a). Id. at 1171, 1173–74 & n.3. Showing that a personnel decision
    is tainted by the consideration of age is sufficient for liability to attach. Id. at 1171.
    Under Babb, § 633a(a)’s textual mandate is clear. The federal government is
    foreclosed from making personnel decisions where there is a taint of “differential treatment
    based on age.” Id. at 1173–74. This requirement, as indicated by the statute’s text, is not
    limited to a specific type of differential treatment. “Any” directly precedes and modifies
    “discrimination” as an adjective. See § 633a(a). Section 633a(a) thus outlaws “any”
    differential treatment, meaning the type of differential treatment is “one or another taken
    at random” or “selected without restriction.” Although the majority indicates its task is to
    determine whether the phrase “any discrimination based on age” includes disparate-impact
    claims, it underestimates the meaning of “any.” See Majority Op. 9, 16–19, & n.12. In
    this instance, “any” directly impacts the types of claims encompassed by § 633a(a) because
    Congress could have used a restrictive word to prohibit certain types of discrimination
    within the federal government but to encompass others. For example, Congress could have
    30
    USCA4 Appeal: 20-1342      Doc: 29         Filed: 11/17/2021      Pg: 31 of 47
    placed “intentional” or “unintentional” before “discrimination,” which would have thus
    limited § 633a(a)’s reach to either disparate-treatment or disparate-impact claims. But it
    did not. Congress instead put the word “any,” which must be given an expansive meaning.
    Babb, 140 S. Ct. at 1173 n.2
    Again, disparate-treatment and disparate-impact claims are both forms of
    discrimination. See Raytheon Co., 
    540 U.S. at 52
    ; Biggins, 
    507 U.S. at 609
    ; Burwell, 
    633 F.2d at 369
    . In other words, they both fall under the umbrella of discrimination that the
    statute is meant to address. Section 633a(a) protects federal employees from experiencing
    “any discrimination,” so the specific differential treatment one suffers is “taken at random”
    and “without restriction” under § 633a(a)’s terms. § 633a(a) (emphasis added). Thus,
    under this literal reading, “any discrimination” must include both disparate-treatment and
    disparate-impact claims because they are distinct types of discrimination, “taken at
    random” and “without restriction,” that can be suffered by a federal employee. 2 Id.
    (emphasis added). This textual inquiry should end the matter.
    2
    The majority theorizes that the Supreme Court’s interpretation of “‘any’ is used as
    a quantitative description of the amount of discrimination permitted (i.e., none),” making
    “free from any amount of discrimination” functionally equivalent to “free from any
    discrimination.” Majority Op. 18 n.12. This does not aid the majority unless it believes
    that disparate-impact liability does not involve any amount of discrimination. In my view,
    disparate-impact claimants suffer some amount of discrimination because they are
    excluded by an employer’s facially neutral policy and, therefore, are victims of
    discrimination. See Connecticut v. Teal, 
    457 U.S. 440
    , 455 (1982) (“Title VII does not
    permit the victim of a facially discriminatory policy to be told that he has not been wronged
    because other persons of his or her race or sex were hired. That answer is no more
    satisfactory when it is given to victims of a policy that is facially neutral but practically
    discriminatory.” (emphasis added)); see also Chrisner v. Complete Auto Transit, Inc., 
    645 F.2d 1251
    , 1257 (6th Cir. 1981) (“Disparate impact analysis is properly applied where the
    (Continued)
    31
    USCA4 Appeal: 20-1342      Doc: 29         Filed: 11/17/2021     Pg: 32 of 47
    The opposite textual interpretation, which the majority adopts, contains a fatal flaw.
    When “any discrimination” is construed to foreclose disparate-impact claims and only
    permit disparate-treatment claims, then “any” imposes a “restriction” rather than, as its
    plain meaning would suggest, indicating “without restriction.” This is so because, per the
    majority’s reading, § 633a(a) is limited to prohibiting only one form of discrimination
    (disparate treatment) while allowing another form of discrimination (disparate impact) to
    go unchecked. Under this view, “any” is rendered to impose a “restriction,” thereby
    changing the statutory language within § 633a(a). Thus, any reading that § 633a(a) only
    outlaws disparate treatment cuts against the Court’s instruction to give “any” an expansive
    meaning. Babb, 140 S. Ct. at 1173; see also Coosemans Specialties, Inc. v. Dep’t of Agric.,
    
    482 F.3d 560
    , 564 (D.C. Cir. 2007) (observing that the use of “any” to modify verbs
    “contemplates a wide range of behavior”). No court possesses the authority to rewrite
    statutory language duly enacted by Congress. See Seminole Tribe of Fla. v. Florida, 
    517 U.S. 44
    , 76 (1996); La. Pub. Serv. Comm’n v. Fed. Commc’ns Comm’n, 
    476 U.S. 355
    , 376
    (1986).
    The only qualification upon “any discrimination” is that it be “based on
    age.” § 633a(a). “Based on age” simply requires age to be a but-for cause of the specific
    discrimination results not from the decision to employ a challenged practice, but from its
    effect.” (emphasis added)). Finding that disparate-impact claims involve some amount of
    discrimination fully aligns with the Court’s precedents because such claims would be null
    otherwise. Cf. Young v. United Parcel Serv., Inc., 
    135 S. Ct. 1338
    , 1345 (2015) (“We note
    that employment discrimination law also creates with is called a ‘disparate-impact’
    claim.”).
    32
    USCA4 Appeal: 20-1342      Doc: 29          Filed: 11/17/2021     Pg: 33 of 47
    discriminatory policy or treatment at issue, not the ultimate employment decision. 3 Babb,
    140 S. Ct. at 1173–74. Since it addresses the substantive merits of a claim, but-for cause’s
    existence is irrelevant to the threshold question of whether a specific cause of action even
    exists under § 633a(a). See Nw. Airlines, Inc. v. Transp. Workers Union of Am., 
    451 U.S. 77
    , 88 n.20 (1981) (“Because we conclude no right to contribution exists under either the
    statute or the federal common law, we need not decide whether the elements of a
    contribution claim have been established in this case.”); Nat’l R.R. Passenger Corp. v.
    Nat’l Ass’n of R.R. Passengers, 
    414 U.S. 453
    , 465 n.13 (1974) (“Since we hold that no
    right of action exists, questions of standing and jurisdiction became immaterial.”).
    The majority insists Babb “looks to the motivation behind, rather the effect of, the
    decision.” Majority Op. at 17. But Babb “looks” to no such thing. Babb only addresses
    the appropriate causal standard for imposing liability on the federal government in
    disparate-treatment cases. 140 S. Ct. at 1171 (“We are asked to decide whether [§ 633a(a)]
    imposes liability only when age is a ‘but-for cause’ of the personnel action in question.”
    3
    In the disparate-impact context, causation is typically demonstrated when a
    claimant shows a “specific or particular employment practice that has created the disparate
    impact under attack.” Wards Cove Packing Co., Inc. v. Atonio,

    (emphasis added), superseded on other grounds by statute, 42 U.S.C. § 2000e-2(k), as
    recognized in Tex. Dep’t of Hous. & Cmty. Affs. v. Inclusive Cmtys. Project, Inc., 
    576 U.S. 519
    , 542 (2015). Our Court has observed disparate-impact claimants must “‘demonstrate
    that the disparity they complain of is the result of one or more of the [] practices that they
    are attacking . . . , specifically showing that each challenged practice has a significantly
    disparate impact’ on the protected class.” Reyes v. Waples Mobile Home Park Ltd. P’ship,
    
    903 F.3d 415
    , 425 (4th Cir. 2018) (emphasis added) (quoting Wards Cove, 
    490 U.S. at 657
    ); see also Anderson v. Westinghouse Savannah River Co., 
    406 F.3d 248
    , 266 (4th Cir.
    2005).

    (emphasis added)). As conceded by my fine colleagues in the majority, Babb has nothing
    to say about disparate-impact claims, and the decision does not even include the word
    “effect” within its reasoning. 4 See 
    id.
     at 1171–78. Moreover, Justice Sotomayor, joined
    by Justice Ginsburg observed that Babb “does not foreclose § 633a claims arising from
    discriminatory processes.” 140 S. Ct. at 1178 (Sotomayor, J., concurring). Thus, Babb
    does not address the essential question here: Does § 633a(a)’s express language, which
    requires the federal government to make personnel decisions untainted by “any
    discrimination based on age,” encompass disparate-impact claims?
    In my view, disparate-treatment and disparate-impact claims are both contemplated
    by § 633a(a)’s expansive use of and proscription on “any discrimination.” See Bostock v.
    Clayton Cnty., 
    140 S. Ct. 1731
    , 1737 (2020) (“[T]he limits of the drafters’ imagination
    supply no reason to ignore the law’s demands.”). And the only qualification for proving a
    disparate-impact claim is that it be “based on age,” mandating that a disparate-impact
    claimant show a causal relationship between the discriminatory treatment and age.
    4
    After suggesting “‘differential treatment’ directs the statute’s focus” to a federal
    employer’s actions, the majority posits that because § 633a(a) “protects against decisions
    in which ‘age discrimination plays any part in the way a decision is made,’” § 633a(a) only
    looks to the “motivation, rather than the effect of,” an employment-related decision.
    Majority Op. at 17–18 (citations omitted). I disagree. First, under the majority’s view,
    “differential treatment” only concerns intentional discrimination, but binding precedent
    indicates that, regardless of intentionality and no matter the form it takes, discrimination is
    discrimination. See Raytheon Co., 
    540 U.S. at 52
    ; Biggins, 
    507 U.S. at 609
    ; Burwell, 
    633 F.2d at 369
    . Second, to suggest a federal employer’s express adoption or employ of a
    neutral policy with a discriminatory effect does not involve a decision by that employer
    simply strains credulity. Watson, 
    487 U.S. at 990
     (“[A] facially neutral practice, adopted
    without discriminatory intent, may have effects that are indistinguishable from
    intentionally discriminatory practices.” (emphasis added)).

    Although this textual inquiry alone dictates the outcome here, our other tools of statutory
    interpretation further establish that § 633a(a) encompasses disparate-impact claims.
    B.
    Section 633a(a)’s inclusion of disparate-impact claims is further supported
    by § 633a(a)’s intertwined history with and similarity to Title VII’s federal-sector ban on
    employment discrimination. As such, historical background concerning the ADEA and
    Title VII is warranted, as it reveals how the majority is overruling our precedents
    construing Title VII. Smith v. City of Jackson, 
    544 U.S. 228
    , 233–34 (2005) (observing it
    is appropriate to presume the text within the ADEA and Title VII should have the same
    meaning because of they were enacted “shortly after the other”).
    Title VII prohibits private employers from engaging discriminatory practices
    because of an employee’s race, color, religion, sex, or national origin. Civil Rights Act of
    1964, Pub. L. No. 88-352, § 703, 
    78 Stat. 241
    , 255 (1964) (codified at 42 U.S.C. § 2000e-
    2(a)). Importantly, at the time of its enactment, Title VII only applied to private employers
    and did not contain any provisions prohibiting the federal government from engaging in
    employment discrimination. § 701(b), 78 Stat. at 253 (codified at 42 U.S.C. § 2000e(b)).
    As part of its new law, Congress instructed the Secretary of Labor to formally study age
    discrimination and provide “recommendations for legislation to prevent arbitrary
    discrimination because of age . . . .” § 715, 78 Stat. at 265. After the Secretary of Labor
    reported back, Congress passed the ADEA in 1967, concluding “older workers find
    themselves disadvantaged in their efforts to retain employment, and especially to regain
    35
    USCA4 Appeal: 20-1342      Doc: 29         Filed: 11/17/2021     Pg: 36 of 47
    employment when displaced from jobs . . . .” Age Discrimination in Employment Act of
    1967, Pub. L. No. 90-202, § 2(a)(1), 
    81 Stat. 602
    , 602 (1967) (codified at 
    29 U.S.C. § 621
    (a)(1)). As codified into law, Congress passed the ADEA with the express purposes
    to: (1) “promote employment of older persons based on their ability rather than their age”;
    (2) “prohibit arbitrary age discrimination in employment”; and (3) “help employers and
    workers find ways of meeting problems arising from the impact of age on employment.” §
    2(b), 81 Stat. at 602 (emphasis added) (codified at 
    29 U.S.C. § 621
    (b)). Similar to Title
    VII, the ADEA only applied to private employers and not the federal government. § 11(b),
    81 Stat. at 605 (codified at 
    29 U.S.C. § 621
    (b)). Thus, both statutes only outlawed
    employment discrimination in the private sphere, albeit on different protected traits, but
    neither applied to the federal government.
    Leap forward a few years. In 1971, the Supreme Court handed down Griggs v.
    Duke Power, which held that Title VII recognized disparate-impact claims because it
    “proscribes not only overt discrimination but also practices that are fair in form, but
    discriminatory in operation.” 
    401 U.S. at 431
    . As a statutory basis for its holding, the
    Court specifically cited 42 U.S.C. § 2000e-2(a)(2), which prohibits private employers from
    limiting, segregating, or classifying their employees “in any way which would deprive or
    tend to deprive any individual of employment opportunities or otherwise adversely affect
    his status as an employee” because of race, color, religion, sex, or national origin. Id. at
    426 n.1 (emphasis added). The Griggs Court further reasoned that Congress aimed to
    remove “artificial, arbitrary, and unnecessary barriers to employment when the barriers
    36
    USCA4 Appeal: 20-1342       Doc: 29         Filed: 11/17/2021     Pg: 37 of 47
    operate invidiously on the basis of racial or other impermissible classification.” Id. at 431
    (emphasis added).
    A year later, Congress amended Title VII by passing the Equal Employment
    Opportunity Act of 1972 and extending Title VII’s prohibitions to the federal government.
    Equal Employment Opportunity Act of 1972, Pub. L. No. 92-261, § 11, 
    86 Stat. 103
    , 111
    (1972) (now codified at 42 U.S.C. § 2000e-16(a)). Title VII’s federal-sector ban reads:
    “All personnel actions affecting employees or applicants for employment . . . in executive
    agencies as defined in section 105 of Title 5 . . . shall be made free from any discrimination
    based on race, color, religion, sex, or national origin.” 42 U.S.C. § 2000e-16(a) (emphasis
    added). Two years later, Congress enacted the Fair Labor Standards Amendments of 1974,
    codifying § 633a(a) of the ADEA. Fair Labor Standards Amendments of 1974, Pub. L.
    No. 93-259, § 28(b)(2), 
    88 Stat. 55
    , 74–75 (1974) (now codified at 29 U.S.C. § 633a(a)).
    With the exception of the protected characteristics, the language of Congress’s federal ban
    on age discrimination exactly mirrors Title VII’s federal ban and reads: “All personnel
    actions affecting employees or applicants for employment . . . in executive agencies as
    defined in section 105 of Title 5 . . . shall be made free from any discrimination based on
    age.” § 633a(a) (emphasis added).
    This legislative history supports the existence of disparate-impact claims
    under § 633a(a). It first shows Congress originally passed the ADEA to prohibit “arbitrary
    age discrimination” and urge employers and employees to find solutions to issues “arising
    from the impact of age on employment.” 
    29 U.S.C. § 621
    (b) (emphasis added). Secondly,
    Congress decided to borrow the exact same statutory language from Title VII when it
    37
    USCA4 Appeal: 20-1342      Doc: 29         Filed: 11/17/2021      Pg: 38 of 47
    banned age discrimination within the federal government under the ADEA. Compare 42
    U.S.C. § 2000e-16(a), with 29 U.S.C. § 633a(a). And lastly, when enacting its federal
    discrimination bans based on race, color, religion, sex, and national origin in 1972,
    followed by age in 1974, Congress did so after the Supreme Court handed down Griggs in
    1971, a precedent of “compelling importance.” Smith, 
    544 U.S. at 234
    . Our Court must
    “assume that Congress is aware of existing law when it passes legislation.” Miles v. Apex
    Marine Corp., 
    498 U.S. 19
    , 32 (1990) (citing Cannon v. Univ. of Chi., 
    441 U.S. 677
    , 696–
    97 (1979)); see also N. Start Steel Co. v. Thomas, 
    515 U.S. 29
    , 34 (1995). Griggs relies
    on restrictive statutory language to hold disparate-impact claims are actionable under Title
    VII’s private-sector ban on employment discrimination.            After Griggs, Congress
    knowingly enacted federal bans on employment discrimination, including under the
    ADEA, using statutory language broader than the more restrictive language authorizing
    disparate-impact claims in Griggs. This action strongly suggests that Congress sought to
    prohibit the very same conduct, if not more, than that addressed in Griggs. As a matter of
    statutory interpretation, Congress’s deliberate choice to use broader language than that
    before the Griggs Court cannot go unnoticed, and it compels an equally broad application
    of § 633a(a). See PGA Tour, Inc. v. Martin, 
    532 U.S. 661
    , 689 (2001); Canadian Aviator
    v. United States, 
    324 U.S. 215
    , 222–23 (1945); Nat’l Coal. For Students with Disabilities
    Educ. & Legal Def. Fund v. Allen, 
    152 F.3d 283
    , 290 (4th Cir. 1998).
    But the historical inquiry is not finished. Over a decade after § 633a(a)’s enactment,
    Congress passed the Civil Rights Act of 1991 (CRA of 1991) and codified disparate-impact
    claims against the federal government into Title VII. Civil Rights Act of 1991, Pub. L. No.
    38
    USCA4 Appeal: 20-1342       Doc: 29         Filed: 11/17/2021      Pg: 39 of 47
    102-166, §§ 104–05, 
    105 Stat. 1071
    , 1074–75 (1991) (codified at 42 U.S.C. §§ 2000e(n),
    2000e-2(k)). Because the CRA of 1991 codified disparate-impact liability against the
    federal government only in Title VII, the majority “do[es] not see how Congress could
    have intended to incorporate their substance into the ADEA . . . .” Majority Op. at 22
    (citing Gross v. FBL Fin. Servs., Inc., 
    557 U.S. 167
    , 174 (2009)). But when construing
    federal statutes, our Court “observe[s] that ‘[i]naction . . . is a notoriously poor indication
    of congressional intent.’” Minor v. Bostwick Labs., Inc., 
    669 F.3d 428
    , 436 (2012) (quoting
    Schweiker v. Chilicky, 
    487 U.S. 412
    , 440 (1988) (Brennan, J., dissenting)); see also Zuber
    v. Allen, 
    396 U.S. 168
    , 185 (1969) (“Legislative silence is a poor beacon to follow in
    discerning the proper statutory route.”). In this instance, it is unsurprising that Congress
    left the ADEA unaltered because the CRA of 1991 was expressly enacted to partially
    supersede a Supreme Court decision weakening disparate-impact suits under Title VII,
    Wards Cove Packing Co., Inc. v. Antonio, 
    490 U.S. 642
     (1989). §§ 2–3, 105 Stat. at 1071.
    In my view, the majority places too much emphasis on Congress’s decision to legislate
    against the Supreme Court’s interpretation of disparate-impact claims under Title VII.
    Indeed, in Smith v. City of Jackson, the Court did not construe the CRA of 1991 as
    precluding the existence of disparate-impact liability under the ADEA’s private-sector ban.
    544 U.S. at 240. Quite the opposite. The Court concluded that the CRA of 1991 only alters
    disparate-impact liability under Title VII, and “Wards Cove’s pre–1991 interpretation of
    Title VII’s identical language remains applicable to the ADEA.” Id. Disparate-impact
    liability under the ADEA’s federal-ban on discrimination is simply narrower than
    disparate-impact liability authorized by the CRA of 1991. Thus, I disagree that the CRA
    39
    USCA4 Appeal: 20-1342      Doc: 29         Filed: 11/17/2021     Pg: 40 of 47
    of 1991 necessarily forecloses the existence of disparate-impact liability under § 633a(a)
    because Congress was responding to an entirely different issue raised by a specific
    Supreme Court case.
    C.
    Given this rich history, judicial interpretations of 42 U.S.C. § 2000e-16(a) before
    the enactment of the CRA of 1991 shed light into the existence of disparate-impact claims
    under § 633a(a). As noted above, the language of Title VII’s federal-sector ban on
    discrimination is virtually the same as that in § 633a(a) and thus carries import for a
    statutory analysis. See Wachovia Bank v. Schmidt, 
    546 U.S. 303
    , 305 (2006) (“under the
    in pari materia canon, statutes addressing the same subject matter generally should be read
    ‘as if they were one law’” (quoting Erlenbaugh v. United States, 
    409 U.S. 239
    , 243
    (1972))). Even though the Supreme Court did not speak to the issue, our Court has
    permitted disparate-impact claims against the federal government under § 2000e-16(a) and
    analyzed those claims on the merits prior to the CRA of 1991. See Chisholm v. U.S. Postal
    Serv., 
    665 F.2d 482
    , 488, 496–97 (4th Cir. 1981); Wright v. Nat’l Archives & Records
    Serv., 
    609 F.2d 702
    , 705, 711–13 (4th Cir. 1979). Our sister circuits did the same. See
    Palmer v. Shultz, 
    815 F.2d 84
    , 89–90, 114–16 (D.C. Cir. 1987); Shidaker v. Tisch, 
    833 F.2d 627
    , 629–32 (7th Cir. 1986); Maddox v. Claytor, 
    764 F.2d 1539
    , 1541, 1548–49 (11th
    Cir. 1985); Mortensen v. Callaway, 
    672 F.2d 822
    , 822, 824 (10th Cir. 1982); Coopersmith
    v. Roudebush, 
    517 F.2d 818
    , 821 n.7 (D.C. Cir. 1975).

    USCA4 Appeal: 20-1342      Doc: 29          Filed: 11/17/2021     Pg: 41 of 47
    If § 2000e-16(a) authorized disparate-impact claims before they were codified into
    Title VII, our precedents mandate the same for § 633a(a) since the statutory language is
    identical. Schmidt, 
    546 U.S. at 505
    . But this mandate does not faze the majority. Instead,
    the majority implicitly overrules our pre-1991 precedents analyzing disparate-impact
    claims against the federal government because, under its holding today, those cases could
    have never been brought against the federal government in the first place and their
    underlying assumptions are deemed to have no precedential effect See Majority Op. at 23
    n.15. In my view, only the Supreme Court and an en banc panel of our Court can formally
    overrule the decisions that the majority casts aside so easily. See United States v. Chong,
    
    285 F.3d 343
    , 246–47 (4th Cir. 2002) (“It is well settled that ‘a panel of this court cannot
    overrule, explicitly or implicitly, the precedent set by a prior panel of this court. Only the
    Supreme Court or this court sitting en banc can do that.’” (emphasis added) (quoting
    Mentavlos v. Anderson, 
    249 F.3d 301
    , 312 n.4 (4th Cir. 2001)).
    D.
    The Supreme Court’s precedents, and those of our sister circuits, provide further
    support for a disparate-impact theory under § 633a(a), and do not save the majority’s
    tenuous holding.
    First, in Smith, the Court was tasked with determining whether the ADEA’s private-
    sector ban on discrimination authorized disparate-impact claims. 544 U.S. at 232–33. In
    relevant part, the private-sector ban on discrimination prohibits employers from limiting,
    segregating, or classifying their employees “in any way which would deprive or tend to
    41
    USCA4 Appeal: 20-1342          Doc: 29        Filed: 11/17/2021    Pg: 42 of 47
    deprive any individual of employment opportunities or otherwise adversely affect his status
    as an employee” because of age. 
    29 U.S.C. § 623
    (a)(2) (emphasis added). The Smith Court
    emphasized the statute’s prohibition on employment actions that “otherwise adversely
    affect” employees, reasoning that the text thus “focuses on the effects of the action on the
    employee rather than the motivation for the action of the employer.” 544 U.S. at 235–36
    (emphasis in original) (citations omitted). The Court observed that the ADEA’s statutory
    language was “identical” to the statutory language construed by the Griggs Court, which
    “strongly suggests that a disparate-impact theory should be cognizable under the ADEA.”
    Id. at 233–36. In the addition to relying on the ADEA’s text, Smith also looked to the
    ADEA’s structure and the Equal Opportunity Employment Commission’s (EEOC)
    regulations when holding that § 623(a)(2) authorized a narrow version of disparate-impact
    claims. Id. at 233–40.
    Certainly, § 633a(a) does not precisely mirror § 623(a)(2). Compare § 633a(a), with
    § 623(a)(2). Section 633a(a) is broader than § 623(a)(2) because it is not limited to a
    specific list of prohibited practices. See §§ 623(a)(2), 633a(a); see also Gomez-Perez v.
    Potter,       
    553 U.S. 474
    ,   486–88   (2008).     Nevertheless,   in   a   similar   vein
    to § 623(a)(2), § 633a(a)’s prohibition reaches discriminatory employment actions
    “affecting employees.” 5 Under Smith, the use of “affecting” within both statutes suggests
    The majority distinguishes § 633a(a) from § 623(a)(2) by opining that the former
    5
    uses “affecting” as an adjectival phrase, while the latter uses “affect” as a verb. Majority
    Op. 17 n.11. Again, § 633a(a) states that “[a]ll personnel actions affecting employees or
    applicants for employment . . . shall be made free from any discrimination based on age.”
    Section 623(a)(2) provides that “[i]t shall be unlawful for an employer—to limit, segregate,
    (Continued)
    42
    USCA4 Appeal: 20-1342      Doc: 29         Filed: 11/17/2021      Pg: 43 of 47
    that they similarly focus on effects to some extent and encompass disparate-impact claims.
    But again, this textual similarity does not seem to bother the majority because it instead
    places emphasis on inapposite statutory words, including the word “actions,” to reach its
    desired conclusion about § 633a(a). See Majority Op. at 16.
    The majority also relies upon Smith to hold that disparate-impact liability cannot
    exist under § 633a(a) because the statute does not structurally contain any limiting defenses
    to a disparate-impact suit in contrast to the ADEA’s private-sector ban and Title VII’s
    federal-sector ban on disparate impact. 6 Majority Op. at 18–19. That position is implicitly
    or classify his employees in any way which would . . . otherwise adversely affect [one’s]
    status as an employee, because of such individual’s age . . . .” The majority’s grammatical
    observations are correct, but they do not preclude disparate-impact liability. The central
    question is, what employer-related conduct does the statute address or influence? Section
    633a(a) applies to “[a]ll personnel actions affecting employees,” and only those personnel
    actions not “affecting employees” are free from scrutiny. Section 623(a)(2) bans employer
    actions that “adversely affect” one’s status as an employee. Importantly, “employees” is
    the object within § 633a(a)’s adjectival phrase, and “employee” is likewise the object of
    § 623(a)(2)’s verb. In my view, both statutes functionally encompass disparate-impact
    claims but employ different means to do so—§ 633a(a) seeks to ensure that “[a]ll personnel
    actions affecting employees” are untainted by discrimination, and § 623(a)(2) prohibits
    employers from classifying employees using methods that would “adversely affect” their
    employment status. The adjective and verb distinctions miss the forest for the trees.
    6
    The majority acknowledges there are Equal Opportunity Commission appeals
    recognizing disparate-impact claims under § 633a(a). See Majority Op. at 14 n.9 (citing
    Carpenter v. Peters, EEOC DOC 0120065151, 
    2007 WL 632984
    , at *2 (EEOC Feb. 23,
    2007); Witkowsky v. Babbitt, EEOC DOC 03970122, 
    1998 WL 563824
    , at *3 (EEOC Jan.
    30, 1998)). In addition to those appeals, there are EEOC regulations implicating the
    existence of disparate-impact claims under the ADEA’s federal-sector ban. See 
    29 C.F.R. § 1614.103
    (c) (stating that complaints of discrimination within the federal government
    extend to “all employment policies or practices affecting employees or applicants for
    employment” (emphasis added)); § 1614.204(c) (stating that a class complaint must
    “identify the policy or practice adversely affecting the class” (emphasis added)). The Smith
    Court found it significant that the EEOC’s regulations “authorize relief on a disparate-

    rejected by Babb. The Babb Court did not find it anomalous that Congress chose to hold
    the federal government to a “higher standard” in comparison to other employers. 140 S.
    Ct. at 1177. And it highlighted Congress’s decision to provide a completely different
    statutory scheme to the federal government under § 633a(a). Id. This Court is dealing with
    an entirely distinct statutory structure as noted in Babb. Moreover, regardless of whether
    a claim is for disparate treatment or disparate impact, § 633a(a) includes no codified
    defenses. 7 This is simply a distinction without a difference. Notwithstanding these
    observations, numerous defenses remain available to the federal government, including
    those embodied by judicial precedents before the CRA of 1991. See id. at 240; Wards
    Cove, 
    490 U.S. at
    658–59.
    Secondly, in Gomez-Perez v. Potter, the Court was tasked with determining whether
    § 633a(a)’s text includes a cause of action for retaliation. 
    553 U.S. at 479
    . Relying on its
    prior precedents construing statutory language similar to § 633a(a), the Court held
    that § 633a(a) prohibited retaliation because “[t]he statutory language at issue . . . [was]
    impact theory,” despite “not mentioning disparate impact by name.” 544 U.S. at 239–40.
    Although the majority views the EEOC’s federal-sector regulations as failing to authorize
    disparate-impact claims, I respectfully disagree. The federal-sector regulations plainly
    target the federal government’s policies and practices, which is precisely what claimants
    must challenge to impose disparate-impact liability on an employer. Raytheon Co., 
    540 U.S. at 52
    ; see also Reynolds v. Barrett, 
    685 F.3d 195
    , 201 (2d Cir. 2012); Pacheco v.
    Mineta, 
    448 F.3d 783
    , 787 (5th Cir. 2006). Unlike the majority, I would ascribe some
    weight to the EEOC’s position.
    7
    Prior to the 1991 CRA, there were similarly no codified defenses to Title VII’s
    federal-sector ban on discrimination, and disparate-impact claims were nevertheless
    permitted. See 42 U.S.C. § 2000e-16.
    44

    not materially different” from the that within its other precedents authorizing retaliation
    claims. Id. at 481 (citing Sullivan v. Little Hunting Park, Inc., 
    396 U.S. 229
     (1969);
    Jackson v. Birmingham Bd. of Educ., 
    544 U.S. 167
     (2005)). It further noted that the
    ADEA’s federal-sector ban is a “broad prohibition” on discrimination. Id. at 487. Most
    importantly, the Court held that § 633a(c) waived the federal government’s sovereign
    immunity from retaliation claims because it directly applies to claims under § 633a(a), and
    that there is no requirement for § 633a(a) to “surmount the same high hurdle” for waiving
    sovereign immunity. Id. at 491. Even if § 633a(a) was required to “surmount the same
    high hurdle” to waive the federal government’s sovereign immunity, the Court held that
    the statute already provided the “requisite clarity” to do so. Id. In this final respect, Gomez-
    Perez does not assist the majority. Under Gomez-Perez, § 633a(c) is the emphatic waiver
    of the federal government’s sovereign immunity, not § 633a(a), as the majority seems to
    imply.
    Finally, although the Supreme Court has not addressed the precise question before
    us, several of our sister circuits recognize the possibility of disparate-impact claims under
    § 633a(a) if they are well pled. 8 See Lujan v. Walters, 
    813 F.2d 1051
    , 1052, 1057–58 (10th
    Federal district courts without appellate guidance are split about the existence of
    8
    disparate-impact claims under § 633a(a). Compare Anderson v. Duncan, 
    20 F. Supp. 3d 42
    , 62–63 (D.D.C. 2013) (concluding disparate-impact claims are not cognizable under §
    633a(a)), and Allard v. Holder, 
    840 F. Supp. 2d 269
    , 278–79 (D.D.C. 2012) (same), with
    Karpe v. Chao, 
    416 F. Supp. 3d 1021
    , 1025–28 (S.D. Cal. 2019) (holding that disparate-
    impact claims are cognizable under § 633a(a)), and Breen v. Peters, 
    474 F. Supp. 2d 1
    , 6–
    7 (D.D.C. 2007) (same), and Lagerstrom v. Mineta, 
    408 F. Supp. 2d 1207
    , 1211–13 (D.
    Kan. 2006) (same).

    Cir. 1987); Palmer v. United States, 
    794 F.2d 534
    , 536–37 (9th Cir. 1986). Tellingly, my
    colleagues do not cite to any federal circuits supporting its holding. Majority Op. at 15.
    Instead, they create a circuit split. See Elhady v. Kable, 
    993 F.3d 208
    , 213 (4th Cir. 2021)
    (“We find these decisions persuasive and decline the invitation to create a circuit split.”);
    see also United States v. Hashime, 
    722 F.3d 572
    , 573 (4th Cir. 2013) (Gregory, J.,
    concurring in denial of en banc) (“Our precedent has had the effect of creating an oft-
    dreaded circuit split.” (citations omitted)). I would avoid both the majority’s creation of a
    circuit split and rebuke of our prior precedents.
    E.
    In sum, the majority ignores the broad scope of the ADEA’s federal-sector ban on
    age discrimination. See Majority Op. at 10. The ADEA’s federal-sector ban is textually
    clear, and when viewed alongside its history, purpose, structure, and other employment-
    related statutes, it compels the conclusion that § 633a(a) prohibits employment practices
    “fair in form, but discriminatory in operation.” Griggs, 
    401 U.S. at 431
    . As such, I would
    hold that the ADEA’s federal-sector prohibition on age discrimination imposes liability for
    disparate impact, and the federal government has unquestionably waived its sovereign
    immunity for disparate-impact claims. Babb, 140 S. Ct. at 1176–77; Gomez-Perez, 
    553 U.S. at
    490–91.

    II.
    Judicial decisions have consequences. Today, the majority officially sanctions the
    federal government’s ability to utilize employment policies and practices that adversely
    impact older workers. This result is not supported by the text, history, structure, or
    purposes of the ADEA. And it does not honor the precedents from our Court and, more
    importantly, the Supreme Court. I respectfully dissent in part and would remand Dr.
    DiCocco’s disparate-impact claim under the ADEA for additional proceedings.
