    OPINION OF THE COURT
    _________
    RENDELL, Circuit Judge.
    Matthew Whitaker’s service as Acting Attorney
    General of the United States has engendered both litigation and
    academic debate. The President’s decision to rely on his
    authority under the Federal Vacancies Reform Act, 
    5 U.S.C. §§ 3345
    -3349d (the “Vacancies Reform Act”), to bypass the
    2
    Department of Justice’s order of succession1 and to select an
    employee rather than a Presidentially appointed and Senate-
    confirmed officer to oversee the Department of Justice raised
    significant and largely unresolved constitutional and statutory
    questions. See Anne Joseph O’Connell, Actings, 
    120 Colum. L. Rev. 613
    , 617-18, 657, 662-65, 667-68, 670-71 (2020).
    Garrett Kajmowicz asks us to resolve these questions. We
    decline because we need not do so to decide his case.
    Kajmowicz sued Whitaker, the Bureau of Alcohol,
    Tobacco, Firearms and Explosives (“ATF”), the Director of
    ATF, the United States of America, and the Attorney General
    of the United States, contending that Whitaker’s unlawful
    service as Acting Attorney General rendered a rule he
    promulgated invalid.       Attorney General William Barr,
    however, ratified this rule, meaning that, as long as he did so
    effectively, this rule may stand even if Whitaker served in
    violation of the Vacancies Reform Act or the Appointments
    Clause. We, like the District Court, conclude that this
    ratification forecloses Kajmowicz’s challenge to this rule, so
    we will affirm the District Court’s dismissal without
    addressing the legality of Whitaker’s designation as Acting
    Attorney General.

    28 U.S.C. § 508
     (establishing that, “[i]n case of a vacancy in
    the office of Attorney General,” the Deputy Attorney General
    may serve as Acting Attorney General and, if he is unavailable
    to do so, “the Associate Attorney General shall” do so).
    3
    I.
    A.
    Since the 1790s, Congress has authorized Presidents to
    designate acting officials to temporarily fill vacant
    Presidentially appointed and Senate-confirmed offices yet has
    also restricted who can serve and how long such persons can
    serve as acting officials. See NLRB v. SW Gen., Inc., 
    137 S. Ct. 929
    , 935 (2017). While its first statutes permitted the
    designation of acting officials in only certain departments, see
    Act of May 8, 1792, ch. 37, § 8, 
    1 Stat. 279
    , 281; Act of
    Feb. 13, 1795, ch. 21, 
    1 Stat. 415
    , in the 1860s, Congress
    expanded this permission to cover all “the executive
    department[s] of the government,” Act of July 23, 1868,
    ch. 227, §§ 1, 3, 
    15 Stat. 168
    , 168; see Act of Feb. 20, 1863,
    ch. 45, § 1, 
    12 Stat. 656
    , 656. To balance this expansion of the
    President’s authority, Congress imposed new restrictions
    under the Vacancies Act of 1868 (the “Vacancies Act”): a
    “default rule” specifying which officials the President could
    designate as acting officials and a ten-day time limit on acting
    service. SW. Gen., 
    137 S. Ct. at
    935 (citing §§ 1, 3, 15 Stat. at
    168)). Over the next hundred years, the President’s statutory
    authority to designate acting officials remained largely
    unchanged. See id. (noting that Congress later allowed acting
    officials to serve for 30 days); see also Act of Sept. 6, 1966,
    Pub. L. No. 89-554, §§ 3345-49, 
    80 Stat. 378
    , 425-26
    (codifying the Vacancies Act as amended and revised in the
    United States Code).
    Beginning in the 1970s, Executive Branch officials
    started to claim that they held authority to appoint acting
    officials outside the Vacancies Act and therefore could
    designate acting officials to serve without abiding by the Act’s
    4
    restrictions. See SW. Gen., 
    137 S. Ct. at 935-36
    ; Morton
    Rosenberg, Cong Rsch. Serv., 98-892, The New Vacancies
    Act: Congress Acts to Protect the Senate’s Confirmation
    Prerogative, 2-4 (1998). As the Executive Branch continued
    to flout the Vacancies Act’s limitations in the 1980s, Congress
    amended the Vacancies Act in 1988, confirming that it applied
    to all executive departments and agencies yet extending the
    time limits for acting service to 120 days. SW Gen., 
    137 S. Ct. at 935-36
    ; Rosenberg, supra, at 3. Despite this response,
    throughout the 1990s, the Executive Branch continued to
    disregard the Vacancies Act’s restrictions on the service of
    acting officials, particularly its time limits, so, unsurprisingly,
    “[t]he conflict [between the Executive and Legislative
    Branches] did not abate[.]” O’Connell, supra, at 626; SW
    Gen., 
    137 S. Ct. at 936
    .
    In 1998, Congress responded by replacing rather than
    amending the Vacancies Act. Omnibus Consolidated and
    Emergency Supplemental Appropriations Act of 1999, Pub. L.
    105-277, § 151, 
    112 Stat. 2681
    , 2681-611 to -616 (1998)
    (codified as amended at 
    5 U.S.C. §§ 3345
    -49d); see SW Gen.,
    
    137 S. Ct. at 936
    . The new Vacancies Reform Act represented
    “a reclamation of the Congress’s Appointments Clause
    power.” SW Gen., Inc. v. NLRB, 
    796 F.3d 67
    , 70 (D.C. Cir.
    2015) (citations omitted), aff’d, 
    137 S. Ct. 929
     (2017). The
    Act’s framework consists of five main parts. The Act (1) limits
    which officials can serve as acting officers and recognizes the
    office’s “first assistant” as the default choice, 
    5 U.S.C. § 3345
    ;
    (2) establishes time limits for the length of an official’s service
    as an acting officer, 
    id.
     § 3346; (3) confirms that the Act
    provides “the exclusive means” for appointing acting officers
    subject to a few exceptions, id. § 3347; (4) nullifies and
    prohibits the ratification of certain actions performed in
    5
    violation of the Act, id. § 3348; and (5) requires the Executive
    Branch to report vacancies and acting appointments to
    Congress, id. § 3349. Kajmowicz’s challenge to a rule
    promulgated by Whitaker as Acting Attorney General and its
    subsequent ratification calls for us to consider the fourth part,
    section 3348.
    B.
    In November 2018, Jefferson Sessions III, the Attorney
    General of the United States, resigned. As a result, 
    28 U.S.C. § 508
    —the statute detailing the Department of Justice’s line of
    succession—authorized Deputy Attorney General, Rod
    Rosenstein, to “exercise all the duties of” the Attorney General.
    Nevertheless, President Trump, relying on his authority under
    the Vacancies Reform Act “directed” Whitaker, Sessions’s
    Chief of Staff, “to perform the functions and duties of the office
    of Attorney General, until the position is filled by appointment
    or subsequent designation.” JA 66. Whitaker served as Acting
    Attorney General until William Barr was sworn in as the
    Attorney General of the United States in February 2019.
    During his tenure as Acting Attorney General, Whitaker
    issued a rule (the “Rule”) concerning the scope of the term
    “machinegun” under the Gun Control Act of 1968, 
    18 U.S.C. §§ 921-28
    , and the National Firearms Act, 
    26 U.S.C. §§ 5801
    -
    72. Bump-Stock-Type Devices, 
    83 Fed. Reg. 66,514
     (Dec. 26,
    2018) (codified at 
    27 C.F.R. §§ 447.11
    , 478.11, 479.11). In
    doing so, he exercised the Attorney General’s authority under
    both statutes to promulgate rules and regulations to enforce
    their provisions.2 The Rule provides that a rifle with an
    2
    
    18 U.S.C. § 926
    (a) (“The Attorney General may prescribe
    only such rules and regulations as are necessary to carry out
    6
    attached “bump stock”3 qualifies as a “machinegun” under
    these statutes. Bump-Stock-Type Devices, 83 Fed. Reg. at
    66,514-15, 66,543. Consequently, it prohibits the possession
    of bump stocks after March 26, 2019 and requires individuals
    to surrender or destroy such stocks by this date. Id. at 66,514-
    15, 66,520, 66,530, 66,543.
    the provisions of this chapter . . . .”); 
    26 U.S.C. § 7805
    (a)
    (authorizing “the Secretary” to “prescribe all needful rules and
    regulations for the enforcement of this title”); see 
    26 U.S.C. § 7801
    (a)(2)(A) (explaining that, for the provisions of the
    National Firearms Act, “the term ‘Secretary’ or ‘Secretary of
    the Treasury’ shall . . . mean the Attorney General”).
    Congress transferred the Secretary of the Treasury’s authority
    to enforce the National Firearms Act’s provisions to the
    Attorney General when it moved ATF within the Department
    of Justice. See Homeland Security Act of 2002, Pub. L.
    No. 107-296, §§ 1111-12, 
    116 Stat. 2135
    , 2274-79. In 2003,
    the Attorney General subdelegated his rulemaking authority
    under both statutes to the Director of ATF. See 
    28 C.F.R. § 0.130
    (a)(1)-(2); Organization of the Bureau of Alcohol,
    Tobacco, Firearms, and Explosives, 
    68 Fed. Reg. 4923
    , 4926
    (Jan. 31, 2003).

    When attached to a rifle in place of an ordinary stationary
    stock, a “bump stock” allows the shooter of a semiautomatic
    rifle to approximate the rapid fire of an automatic weapon.
    Guedes v. ATF, 
    920 F.3d 1
    , 7 (D.C. Cir. 2019) (per curiam).
    7
    Several weeks before the Rule’s effective date,
    Kajmowicz, the owner of two bump stocks,4 sued Whitaker
    and others, challenging the Rule. He claimed that the Rule was
    invalid because Whitaker issued it when he was unlawfully
    serving as Acting Attorney General. The next month, Attorney
    General Barr, aware of legal challenges to the Rule, ratified it
    after he “familiarized [himself] with the rulemaking record that
    was before the Acting Attorney General and . . . reevaluated
    those materials without any deference to [the Acting Attorney
    General’s] earlier decision.” Bump-Stock-Type-Devices, 
    84 Fed. Reg. 9239
    , 9240 (Mar. 14, 2019).
    Soon thereafter, Kajmowicz twice amended his
    complaint. The Government moved to dismiss the amended
    complaint for lack of jurisdiction or, in the alternative, for
    failure to state a claim. In turn, Kajmowicz moved for
    summary judgment on his claims. When the District Court
    held argument on these motions several months later,
    Kajmowicz requested leave to amend his complaint for the
    third time, as he wished to add claims that the Vacancies
    Reform Act prohibited the Attorney General from ratifying the
    Rule. The District Court granted this request and dismissed
    both the Government’s and Kajmowicz’s pending motions
    without prejudice.
    Kajmowicz then filed his Third Amended Complaint.
    In it, as he had in his previous complaints, he challenged the
    Rule on the basis that Whitaker’s service as Acting Attorney
    General violated the Vacancies Reform Act and the
    4
    As required by the Rule, Kajmowicz surrendered both stocks
    to ATF in March 2019, and ATF is safekeeping them until
    challenges to the Rule are resolved.

    Appointments Clause and challenged President’s Trump’s
    purported “policy” of employing the Vacancies Reform Act to
    designate employees to serve as officers in violation of the Act
    and the Appointments Clause. For the first time, he alleged
    that the Rule remained invalid despite Attorney General Barr’s
    purported ratification because the Vacancies Reform Act
    prevented Barr from ratifying Whitaker’s promulgation of the
    Rule. The Government, again, moved to dismiss Kajmowicz’s
    complaint for lack of jurisdiction or, in the alternative, for
    failure to state a claim.
    The District Court rejected Kajmowicz’s challenges to
    both the President’s alleged acting-appointments policy and
    the Rule. It first held that Kajmowicz lacked Article III
    standing to pursue his acting-appointments-policy challenge
    because his claimed injury was too speculative to constitute an
    injury in fact.5 Next, the District Court determined Attorney
    General Barr validly ratified the Rule, concluding that the
    Vacancies Reform Act did not prohibit his ratification. Lastly,
    the Court held that the voluntary cessation doctrine provided
    no basis for it to still entertain Kajmowicz’s challenge to
    Whitaker’s appointment because the ratification did not moot
    his claims, and, even if it did, the defendants had not mooted
    them. After determining that further amendment would be
    futile, the District Court dismissed Kajmowicz’s acting-
    appointments-policy claims without prejudice yet also without
    leave to amend and dismissed his remaining claims with
    prejudice.
    Kajmowicz timely appealed

    Kajmowicz does not challenge this determination on appeal.

    II.
    The District Court had jurisdiction under 
    28 U.S.C. § 1331
    . We have jurisdiction under 
    28 U.S.C. § 1291
    . “We
    review a District Court’s dismissal of a complaint under
    Federal Rule of Civil Procedure 12(b)(6) de novo.” Schmidt v.
    Skolas, 
    770 F.3d 241
    , 248 (3d Cir. 2014). In this review, “we
    accept all well-pleaded allegations as true and construe them
    in the light most favorable to the non-moving party.” Ellison v.
    Am. Bd. of Orthopaedic Surgery, 
    11 F.4th 200
    , 204 n.2 (3d Cir.
    2021). To survive a motion to dismiss for failure to state a
    claim, the complaint “must contain enough facts to state a
    claim for relief that is plausible on its face.” Martinez v.
    UPMC Susquehanna, 
    986 F.3d 261
    , 265 (3d Cir. 2021)
    (internal quotation marks and citation omitted).
    III.
    Kajmowicz urges us to set aside the Rule because
    Whitaker issued it while he was serving as Acting Attorney
    General, allegedly in violation of the Vacancies Reform Act.
    The Rule’s validity, however, no longer necessarily rests on
    Whitaker’s authority because Attorney General Barr ratified
    the Rule in March 2019. If a lawfully appointed official ratifies
    his predecessor’s action and does so in accordance with the
    law, that ratification may “remedy a defect arising from the
    decision of an improperly appointed” predecessor. Moose
    Jooce v. FDA, 
    981 F.3d 26
    , 28 (D.C. Cir. 2020) (holding that
    an FDA Commissioner’s ratification of a rule “cured any
    Appointments Clause defect” in the rule when it was issued);
    see NLRB v. Newark Elec. Corp., 
    14 F.4th 152
    , 160-63 (2d Cir.
    2021) (holding that the NLRB General Counsel’s ratification
    of the Acting General Counsel’s action resolved the appellee’s
    challenge to this action based on the Acting General Counsel’s
    10
    unlawful service under the Vacancies Reform Act); CFPB v.
    Gordon, 
    819 F.3d 1179
    , 1190-92 (9th Cir. 2016) (holding that
    the CFPB Director’s ratification of his earlier decision to bring
    an enforcement action after he was validly appointed “resolves
    any Appointments Clause deficiencies” in this enforcement
    action). For his ratification to cure such a defect, the ratifying
    official must (1) “at the time of the ratification, . . . have the
    authority to take the action to be ratified,” (2) “have full
    knowledge of the decision to be ratified,” and (3) “make a
    detached and considered affirmation of the earlier decision.”
    Advanced Disposal Servs. E., Inc. v. NLRB, 
    820 F.3d 592
    , 602
    (3d Cir. 2016).
    Despite challenging the Rule’s ratification, Kajmowicz
    does not argue that Attorney General Barr failed to satisfy these
    three requirements. See 
    id. at 604
     (placing the burden on the
    party challenging an agency’s ratification to allege facts that
    “cast[] doubt” on the purported ratification). Indeed, the
    ratification does not appear to be lacking in this respect. See
    Bump-Stock-Type-Devices, 84 Fed. Reg. at 9240. Rather, he
    maintains that Attorney General Barr’s ratification does not
    resolve this case because he contends that the Vacancies
    Reform Act prohibited it. We disagree.
    A.
    Just as with any other question of statutory
    interpretation, we turn first to the Vacancies Reform Act and
    its text. See Rotkiske v. Klemm, 
    890 F.3d 422
    , 424-25 (3d Cir.
    2018) (en banc), aff’d, 
    140 S. Ct. 355
     (2019). The Act bars
    ratification of “action[s] taken . . . in the performance of any
    function or duty of” a Presidentially appointed and Senate-
    confirmed office. 
    5 U.S.C. § 3348
    (d) (emphasis added). It
    also provides two definitions of a “function or duty,” and the
    11
    parties agree that Whitaker’s promulgation of the Rule
    implicates the first: a “function or duty of the applicable office”
    that “(i) is established by statute; and (ii) is required by statute
    to be performed by the applicable officer (and only that
    officer).” 
    5 U.S.C. § 3348
    (a)(2)(A) (emphasis added).6
    Whether the Act prohibited the Attorney General’s purported
    ratification requires us to consider this definition’s latter half—
    when does a statute “require[]” an “officer (and only that
    officer)” to exercise the authority it creates?
    To start, we consider the statute’s plain meaning.
    Burton v. Schamp, 
    25 F.4th 198
    , 207 (3d Cir. 2022). “Th[e]
    statutory language is unambiguous: the [Vacancies Reform
    Act] applies only to functions and duties that a [Presidentially
    appointed and Senate-confirmed] officer alone is permitted by
    statute . . . to perform. It does not apply to delegable functions
    and duties.” Arthrex, Inc. v. Smith & Nephew, Inc., 
    35 F.4th 1328
    , 1336 (Fed. Cir. 2022). The District Court adopted this
    same reading, determining that “function[s] and dut[ies]” are
    only those “nondelegable functions made exclusive to [a]
    specific office by a statute[.]” JA 12. Of course, the Vacancies
    Reform Act includes neither the terms nondelegable nor
    exclusive. See L.M-M. v. Cuccinelli, 
    442 F. Supp. 3d 1
    , 33
    (D.D.C. 2020). But Congress need not have included these
    terms when it already included the parenthetical qualifier “and
    only that officer[.]” 
    5 U.S.C. § 3348
    (a)(2)(A)(ii).
    6
    We refer to the authority covered by this definition as
    “statutory functions or duties.” The other definition concerns
    “function[s] or dut[ies] . . . established by regulation[.]” 
    Id.
    § 3348(a)(2)(B). We refer to authority covered by this
    definition as “regulatory functions or duties.”
    12
    The concept of delegation, more specifically
    subdelegation,7 as section 3348(a)(2)(A)’s text makes clear,
    helps define the statute’s scope. As the District Court
    reasoned, a statute “require[s]” a specific “officer (and only
    that officer)” to perform the function only if the statute
    prohibits the delegation of that function. Id. On the other hand,
    if a statute tasks an officer with certain responsibilities yet
    permits him to subdelegate them, then it does not “require[]”
    that “officer (and only that officer)” to exercise that authority.
    Id. (emphasis added).         Put differently, under section
    3348(a)(2)(A), the key question is whether the statute makes
    the authority “exclusive” to the office in which it vests that
    authority and thereby limits an officer’s ability to reassign it.
    Stand Up for Cal.! v. U.S. Dep’t of Interior, 
    994 F.3d 616
    , 622
    (D.C. Cir. 2021), cert. denied, 
    142 S. Ct. 711
     (2022).
    To determine whether a statute creates an exclusive
    grant of statutory authority, we simply read that statute. Under
    the subdelegation doctrine, “[w]hen a statute delegates
    authority to a federal officer or agency, subdelegation . . . is
    presumptively permissible absent affirmative evidence of a
    contrary congressional intent.” La. Forestry Ass’n, 745 F.3d
    at 671 (first alteration in original) (quoting U.S. Telecom
    Ass’n v. FCC,

    Cir. 2014)

    sibling circuits that have spoken on this issue are unanimous in
    permitting subdelegations to subordinates, even where the
    enabling statute is silent, so long as the enabling statute and its
    legislative history do not indicate a prohibition on
    subdelegation”). We see no reason to suspect that Congress
    intended for courts to approach such questions any differently
    when resolving them in the context of Vacancies Reform Act
    challenges. See In re VistaCare Grp., LLC, 
    678 F.3d 218
    , 226
    (3d Cir. 2012) (“When Congress enacts legislation, it is
    presumed to act with knowledge of the existing law and
    judicial concepts.” (internal quotation marks and citation
    omitted)). So, to ascertain whether a statutory duty constitutes
    a “function or duty” under section 3348(a)(2)(A) and, as a
    result, whether an official may ratify an exercise of that duty,
    we examine the text of the statute, considering also the
    presumption of subdelegability. If we read the statute’s text to
    expressly bar subdelegation or mandate exclusivity, then the
    authority constitutes a “function or duty.” If not, the statutory
    authority does not qualify as a “function or duty,” and officials
    may ratify exercises of that authority under the Vacancies
    Reform Act.8
    8
    We do not presume that courts should necessarily apply this
    same approach for regulatory functions or duties despite
    Congress’s use of similar language in both function or duty
    definitions. See 
    5 U.S.C. § 3348
    (a)(2)(B). Even though courts
    generally employ the same tools of “statutory construction”
    when interpreting regulations, Arcos Sanchez v. Att’y Gen.,
    
    997 F.3d 113
    , 119-20 (3d Cir. 2021), courts have only recently
    considered whether they should read regulations to
    presumptively allow redelegation as they do when interpreting
    statutes, see, e.g., Stand Up for Cal.!, 994 F.3d at 623
    14
    Despite section 3348(a)(2)(A)’s plain meaning,
    Kajmowicz resists this approach, arguing that, if a statute
    assigns a duty to a single office rather than multiple offices,
    then it does so exclusively. He would have us stress “the
    applicable officer (and only that officer)” and elide “required
    by statute to be performed by.” 
    5 U.S.C. § 3348
    (a)(2)(A). But
    we cannot do so. Loughrin v. United States, 
    573 U.S. 351
    , 358
    (2014) (rejecting an interpretation that “runs afoul of the
    cardinal principle of interpretation that courts must give effect,
    if possible, to every clause and word of a statute” (internal
    quotation marks and citation omitted)). Instead, we must give
    effect to Congress’s decision to define a “function or duty” in
    terms of what the statute requires, not what it permits. If we
    read an assignment of authority to one officer as prohibiting
    any other officer from exercising that authority, we would
    stand the subdelegation doctrine on its head—presuming
    statutory silence implies exclusivity. See United States v.
    Mango, 
    199 F.3d 85
    , 90 (2d Cir. 1999) (“Congress may
    mention a specific official only to make it clear that this official
    has a particular power rather than to exclude delegation to other
    officials.” (citing Shook v. D.C. Fin. Responsibility & Mgmt.
    Assistance Auth., 
    132 F.3d 775
    , 782 (D.C. Cir. 1998))). By
    asking courts to consider whether the relevant statute
    “require[s] . . . the applicable officer (and only that officer)” to
    perform the duty at issue, Congress directed courts to read
    statutes silent on the question of delegation with the
    subdelegation doctrine in mind. In other words, we should
    conclude that a statute grants authority exclusively to an office
    only if the statute so states or is otherwise read, using the
    (recognizing for the first time that the subdelegation doctrine’s
    “presumption applies to regulations”).
    15
    traditional principles of statutory interpretation, to foreclose
    further delegation of that authority.
    When we review the National Firearms Act and the Gun
    Control Act of 1968, we see no express nor implicit restrictions
    on the Attorney General’s ability to subdelegate his
    rulemaking authority to subordinates.          See 
    26 U.S.C. § 7805
    (a); 
    18 U.S.C. § 926
    (a). Indeed, Kajmowicz concedes
    that the Attorney General can subdelegate this authority, and,
    in fact, the Attorney General subdelegated it to the Director of
    ATF, who has exercised this rulemaking authority since 2003.
    See 
    28 C.F.R. § 0.130
    (a)(1)-(2); Organization of the Bureau of
    Alcohol, Tobacco, Firearms, and Explosives, 68 Fed. Reg. at
    4926. Therefore, neither statute “required” the Attorney
    General “and only [the Attorney General]” to exercise that
    authority. 
    5 U.S.C. § 3348
    (a)(2)(A). And so, this rulemaking
    authority does not qualify as a “function or duty” of the
    Attorney General.9
    B.
    Losing on the text, Kajmowicz advances arguments
    rooted in the Vacancies Reform Act’s purpose and legislative
    history. Yet, where, as here, the statute’s language is
    unambiguous, our work is done. Bostock v. Clayton Cnty., 140
    9
    We note that our decision concerns only the particular
    rulemaking authority at issue. As a result, we do not decide
    whether authority made delegable under a general delegation
    statute, such as 
    28 U.S.C. § 510
     (permitting the Attorney
    General to subdelegate any of the office’s functions), would
    constitute a statutory function or duty under 
    5 U.S.C. § 3348
    (a)(2)(A).
    
    16 S. Ct. 1731
    , 1749 (2020) (declining to consider legislative
    history when the statutory text was unambiguous). To the
    extent Kajmowicz insists that we must jettison section 3348’s
    plain language to avoid an absurd result, we are unconvinced.
    See Riccio v. Sentry Credit, Inc., 
    954 F.3d 582
    , 588 (3d Cir.
    2020) (en banc) (“As long as Congress could have any
    conceivable justification for a result—even if the result carries
    negative consequences—that result cannot be absurd.”).
    Though he claims that we risk defanging the Vacancies Reform
    Act, he must raise his policy concerns elsewhere. See
    Barnhart v. Sigmon Coal Co., 
    534 U.S. 438
    , 461-62 (2002);
    United States v. Safehouse, 
    985 F.3d 225
    , 238 (3d Cir. 2021)
    (“The public-policy debate is important, but it is not one for
    courts.”).
    Still, we acknowledge that most statutes that confer
    authority will permit subdelegation, which means that many
    statutory functions and duties will be ratifiable under the
    Vacancies Reform Act. See Stand Up for Cal.! v. U.S. Dep’t
    of Interior, 
    298 F. Supp. 3d 136
    , 137 (D.D.C. 2018) (“[I]n
    practice, there are very few duties that cannot be delegated to
    an ‘acting’ officeholder . . . or even another official who acts
    in the place of the principal pursuant to agency regulations or
    orders.”), aff’d, 
    994 F.3d 616
     (D.C. Cir. 2021); see also
    Arthrex, 35 F.4th at 1337 (noting that the scope of section 3348
    is “vanishingly small”). Congress, however, can always
    recalibrate section 3348. If it wishes, it can bring statutory
    duties within section 3348(d)’s ambit by writing or rewriting
    those statutes to require only the named officer perform those
    duties. See Stand Up for Cal.!, 994 F.3d at 622.
    Moreover, a broad reading of section 3348(d) would
    effectively cripple the operation of the federal government.
    See O’Connell, supra, at 631 (explaining that, under section
    17
    3348, “officials serving in violation of the [Vacancies Reform]
    Act can be treated more harshly than those operating
    unconstitutionally” as the Act prevents them from relying on
    “harmless error defense[s] or the de facto officer doctrine”);
    see also Arthrex, 35 F.4th at 1337 (explaining that a broad
    reading of “function or duty” would threaten to nullify
    thousands of patents and many inter partes review decisions
    when applied to the Director of the Patent and Trademark
    Office). Congress can impose that strong medicine if it wishes,
    but it has not done so in section 3348. Rather, it struck a
    balance between deterring the Executive Branch from violating
    the Vacancies Reform Act and ensuring the Branch could
    continue to function when it did overstep the Act’s limits. See
    Arthrex, 35 F.4th at 1337 (noting that, even in the face of
    “disquieting” results, courts “can neither rewrite [section 3348]
    nor supplant Congress’ judgment”).
    Finally, section 3348(d)(2)’s purported relationship to
    the D.C. Circuit’s decision in Doolin Security Savings Bank,
    F.S.B. v. Office of Thrift Supervision, 
    139 F.3d 203
     (D.C. Cir.
    1998), provides no reason to look beyond the statute’s plain
    meaning. The Vacancies Reform Act’s legislative history
    suggests Congress wanted to “overturn” Doolin, S. Rep.
    No. 105-250, at 11 (1998), but “the authoritative statement is
    the statutory text, not the legislative history or any other
    extrinsic material,” Exxon Mobil Corp. v. Allapattah Servs.,
    Inc., 
    545 U.S. 546
    , 568 (2005). Because Congress did not
    specify in section 3348’s text that it intended to overrule
    Doolin, even if the language Congress chose was unsuccessful
    in achieving this end, we could not fix Congress’s mistake. See
    S.H. ex rel. Durrell v. Lower Merion School Dist., 
    729 F.3d 248
    , 259 (3d Cir. 2013).
    18
    Besides, section 3348’s text ensures that no court could
    decide Doolin in the same way today. Doolin involved two
    Acting Directors of the Office of Thrift Supervision. 139 F.3d
    at 205. The first assumed this role after the Senate-confirmed
    director subdelegated all his authority then resigned. Id. This
    first Acting Director served about four years and initiated the
    agency action at issue in Doolin. Id. Then, following the first
    Acting Director’s resignation, the President named a new
    Acting Director pursuant to his authority under the Vacancies
    Act. Id. The second Acting Director issued a final order in the
    agency action before he was replaced by a Senate-confirmed
    Director. Id. at 205-06. The court held that the second Acting
    Director’s service was lawful, id. at 211, and it declined to
    resolve whether the first Acting Director’s designation and
    four years of service were lawful because the second Acting
    Director effectively ratified the challenged action. Id. at 214-
    15.
    Doolin principally concerned timing, not ratification.
    See id. at 206-11. Congress effectively overruled the timing
    portion of the court’s decision by amending section 3346’s
    language in the Vacancies Reform Act.10 The Act also
    introduced new statutory language that addressed ratification.
    That, however, does not mean that Congress drafted section
    3348 to restrict ratification as drastically as Kajmowicz would
    have it. The Doolin court presumed that a lawfully appointed
    10
    In Doolin, the court held that the time limitation on an acting
    official’s service began to run when that official took office.
    139 F.3d at 208-09. The Vacancies Reform Act’s statutory
    language effectively overrules that part of Doolin by clarifying
    that the time limitation begins to run “on the date the vacancy
    occurs.” 
    5 U.S.C. § 3346
    (a)(1).
    19
    officer could ratify any action performed by an unlawfully
    serving acting predecessor. See 
    id. at 213-214
    . In response,
    Congress superseded that proposition: under the Vacancies
    Reform Act, officials could no longer ratify all actions, only
    those that rested on exercises of delegable authority. See 
    5 U.S.C. § 3348
    . Thus, the Vacancies Reform Act requires no
    atextual gloss to overrule both parts of Doolin.
    At bottom, Congress did not require that the Attorney
    General and only the Attorney General exercise the rulemaking
    authority assigned to him under the National Firearms Act and
    the Gun Control Act of 1968, so this authority does not qualify
    as one of the Attorney General’s “function[s] or dut[ies]” under
    section 3348(a)(2)(A). As a result, even if Whitaker served as
    Acting Attorney General in violation of the Vacancies Reform
    Act, section 3348(d)(2) did not prohibit Attorney General Barr
    from ratifying Whitaker’s promulgation of the Rule. Because
    this ratification cured any defects in the rule related to
    Whitaker’s service, Kajmowicz’s challenge to the Rule fails
    whether or not Whitaker’s designation violated the Vacancies
    Reform Act or the Appointments Clause. See Guedes, 920
    F.3d at 12.
    IV.
    Despite Attorney General Barr’s valid ratification of the
    Rule, Kajmowicz invites us to still decide whether Whitaker
    served unlawfully as Acting Attorney General. He contends
    that, because the Government has not satisfied its burden under
    the voluntary cessation doctrine to show that the Executive
    Branch officials will not repeat the conduct he challenges, we
    should reach the merits of his claims even though Attorney
    General Barr sought to “moot” these claims by ratifying the
    Rule. Again, we disagree.
    20
    The voluntary cessation doctrine describes a special
    application of our mootness doctrine.11 Hartnett v. Pa. State
    Educ. Ass’n, 
    963 F.3d 301
    , 306-07 (3d Cir. 2020) (explaining
    that, rather than an exception, “[v]oluntary cessation is just a
    recurring situation in which courts are particularly skeptical of
    mootness arguments”). Under the doctrine, even though a case
    appears moot due to “a defendant’s voluntary cessation of a
    challenged practice,” we may still “determine the legality of
    [that] practice” aware that the defendant could “return to his
    old ways” if we were not to intervene. Friends of the Earth,
    Inc. v. Laidlaw Env’t Servs. (TOC), Inc., 
    528 U.S. 167
    , 189
    (2000) (internal quotation marks and citation omitted). In
    these circumstances, the defendant must “show[] that it is
    absolutely clear the allegedly wrongful behavior could not
    reasonably be expected to recur” for us to dismiss the case as
    moot. 
    Id. at 190
    ; see Hartnett, 963 F.3d at 306-07.
    The voluntary cessation doctrine, however, is irrelevant
    here: Attorney General Barr’s ratification did not “moot”
    Kajmowicz’s case. As the D.C. Circuit explained when it
    considered this same argument in response to the same
    11
    “A case becomes moot—and therefore no longer a ‘Case’ or
    ‘Controversy’ for purposes of Article III—when the issues
    presented are no longer ‘live’ or the parties lack a legally
    cognizable interested in the outcome.” Already, LLC v. Nike,
    Inc., 
    568 U.S. 85
    , 91 (2013) (internal quotation marks and
    citation omitted). In other words, once it becomes “impossible
    for a court to grant any effectual relief whatever to the
    prevailing party,” then we no longer have jurisdiction and must
    dismiss the case as moot. Campbell-Ewald Co. v. Gomez, 
    577 U.S. 153
    , 161 (2016) (internal quotation marks and citation
    omitted).
    21
    ratification, “a properly appointed official’s ratification of an
    allegedly improper official’s prior action, rather than mooting
    a claim, resolves the claim on the merits by remedy[ing] [the]
    defect (if any) from the initial appointment.” Guedes, 920 F.3d
    at 13 (alterations in original) (internal quotation marks and
    citation omitted). Unsurprisingly, the same is true here.
    Attorney General Barr’s “ratification purge[d] any residual
    taint or prejudice left over from [Whitaker’s] allegedly invalid
    appointment” and thus “resolv[ed] the merits of [Kajmowicz’s]
    claim.” Id. Simply put, the ratification rendered the legal
    theory underpinning Kajmowicz’s challenge meritless without
    mooting his case; it did not “eliminate [his] personal stake in
    the outcome of [the] suit [n]or prevent a court from being able
    to grant the requested relief.” Hamilton v. Bromley, 
    862 F.3d 329
    , 335 (3d Cir. 2017) (internal quotation marks and citation
    omitted). Kajmowicz doubtless could still challenge the Rule
    on other grounds if he so wished. See Guedes, 920 F.3d at 17,
    32 (considering additional challenges after determining that the
    rule’s ratification resolved the merits of an Appointments
    Clause challenge).
    Despite Kajmowicz’s arguments to the contrary,
    Appointments Clause challenges like his do not merit special
    treatment. Although an Appointments Clause violation
    provides grounds to invalidate an unreviewed agency action,
    once a lawfully appointed official reconsiders that action, the
    plaintiff must establish that this violation continues to taint the
    action for a court to set that action aside. See Intercollegiate
    Broad. Sys., Inc. v. Copyright Royalty Bd., 
    796 F.3d 111
    , 123-
    24 (D.C. Cir. 2015). The D.C. Circuit recognized an exception
    to this rule in Landry v. FDIC, 
    204 F.3d 1125
     (D.C. Cir. 2000),
    where the hierarchical nature of agency review meant that the
    plaintiff’s challenge to an administrative law judge’s
    22
    appointment would always be cured before it reached an
    Article III court. Intercollegiate Broad., 796 F.3d at 124
    (citing Landry, 
    204 F.3d at 1130-31
    ). Kajmowicz does not
    face that catch-22—the independent actions of several
    governmental actors, not the structures of agency review, have
    frustrated his attempts to seek judicial intervention. See
    Guedes, 920 F.3d at 13-14 (“The succession of a Presidentially
    appointed and Senate-confirmed Attorney General does not
    remotely implicate the Landry scenario.”). So we face no
    obligation to determine whether Whitaker’s service as Acting
    Attorney General violated the Appointments Clause. See
    Moose Jooce, 981 F.3d at 28-31.
    What is more, the principles of constitutional avoidance
    and judicial restraint guide us not to consider this question.
    These principles counsel courts to avoid deciding issues,
    especially constitutional ones, when they need not do so in
    order to resolve cases. See Lyng v. Nw. Indian Cemetery
    Protective Ass’n, 
    485 U.S. 439
    , 445 (1988) (“A fundamental
    and longstanding principle of judicial restraint requires that
    courts avoid reaching constitutional questions in advance of
    the necessity of deciding them.”). Although Kajmowicz
    disputes the legality of Whitaker’s service as Acting Attorney
    General, this issue does not affect his challenge to the Rule, so
    we need not and therefore will not address it no matter how
    novel, significant, or interesting it may be.
    V.
    Kajmowicz challenged the Rule on the grounds that
    Whitaker lacked the authority to issue it. But, because
    Attorney General Barr effectively ratified the Rule, and the
    Vacancies Reform Act did not prohibit this ratification, the
    Rule will stand even if Whitaker may have served as Acting
    23
    Attorney General in violation of the Vacancies Reform Act or
    the Appointments Clause. Thus, we affirm the District Court’s
    dismissal of Kajmowicz’s complaint for failure to state a claim
    for which relief can be granted.
    24
    FISHER, Circuit Judge, concurring.
    I join Judge RENDELL’s well-reasoned majority
    opinion with one exception. I read the relevant statutory text as
    imposing an additional requirement before we may conclude
    something is not a “function or duty” of a particular office
    under the Federal Vacancies Reform Act (“FVRA”).
    Specifically, the authority in question, in addition to being
    delegable, must actually have been delegated. Because this
    requirement is clearly met in the case before us, I agree we
    should affirm.
    Though the Plaintiff does not prevail, there is good
    reason to stop short of accepting the full scope of the
    Government’s reading. According to the Government, the anti-
    ratification provision at 
    5 U.S.C. § 3348
     does not reach
    functions or duties that “may be vested in multiple officers.”
    Appellee’s Br. at 13 (emphasis added). Rather, the
    Government argues, it extends only to “nondelegable duties.”
    
    Id.
     (quoting Guedes v. ATF, 
    920 F.3d 1
    , 12 (D.C. Cir. 2019)
    (per curiam)). The Government places particular emphasis on
    the existence of the Attorney General’s general delegation
    authority at 
    28 U.S.C. § 510
    . The problem with the
    Government’s interpretation is that it creates a logical
    conundrum. From a plain text perspective, only the Attorney
    General may delegate authority under 
    28 U.S.C. § 510
    .
    Otherwise, lower-level officials could unilaterally exercise
    functions or duties that Congress confided in a department
    head. This suggests that if the Attorney General has not
    actually delegated the authority to undertake a particular
    action, then statutory authority requires the action to be
    1
    performed by only the Attorney General.1
    The following hypothetical helps illustrate this point.
    Assume the Attorney General had never delegated the
    authority to promulgate the gun regulations at issue here prior
    to the vacancy arising. If that were the case, then no other
    officer or entity within the Department of Justice could issue
    the bump-stock regulation. Further, an Acting Attorney
    General could not delegate the authority to issue the regulation
    because only the Attorney General may delegate the Attorney
    General’s functions or duties. See 
    28 U.S.C. § 510
    . Any
    attempted delegation would thus have no force or effect under
    
    5 U.S.C. § 3348
    (d)(1) because the delegation function is an
    exclusive “function or duty” of the Attorney General within the
    meaning of § 3348(a). In such a scenario, the relevant statutes
    would therefore require the Attorney General, and only the
    Attorney General, to be the officer to issue the rule. See id. §
    3348(a).
    Thus, the Government’s suggestion that we look to
    whether a function or duty is delegable under a general
    delegation statute is insufficient because—at least under 
    28 U.S.C. § 510
     and similar provisions—the authority to delegate
    functions or duties is itself nondelegable. Fortunately, this
    hypothetical situation is not before us today because the
    Attorney General has long delegated to the ATF Director the
    authority to issue rules like the bump-stock regulation.
    Nonetheless, considering this hypothetical reveals that
    1
    The result is materially the same under the
    subdelegation doctrine. That doctrine presumptively allows
    officers to delegate their statutory functions or duties to
    subordinate officers, see La. Forestry Ass’n Inc. v. Sec’y U.S.
    Dep’t of Lab., 
    745 F.3d 653
    , 671 (3d Cir. 2014), but does not
    permit them to assume the duties of superior officers.
    2
    the best reading of the FVRA’s anti-ratification provision
    requires us to assess both whether a function or duty is
    delegable and whether it has actually been delegated. Reading
    the relevant statutes together, the Attorney General “shall
    prescribe all needful rules and regulations,” but also “may”
    authorize other officers to perform the functions of the
    Attorney General. See 
    26 U.S.C. §§ 7801
    (a)(2)(A)(ii), 7805(a);
    
    28 U.S.C. § 510
    . In turn, the anti-ratification provision only
    applies to a “function or duty” that is “established by statute”
    and “required by statute to be performed by the applicable
    officer (and only that officer).” 
    5 U.S.C. § 3348
    (a)(2)(A), (d).
    A plain reading of these statutory provisions suggests a
    straightforward inquiry when a vacancy arises: can another
    official besides the Attorney General perform the action in
    question under statutory authority? If the answer is yes, then
    the relevant statutes do not require the action to be performed
    by only the Attorney General. If the answer is no, then they
    require only the Attorney General to perform the action.
    Here, it is undisputed that at least one other officer—the
    ATF Director—could also have promulgated the bump-stock
    rule. See Appellant’s Reply Br. at 26 (“But of course the ATF
    Director retained that authority [to issue the bump-stock
    rule].”). The Attorney General delegated his functions under
    the Gun Control Act and the National Firearms Act to the ATF
    Director when the ATF was transferred from the Treasury
    Department to the Justice Department. 
    28 C.F.R. § 0.130
    (a)(1),
    (2); Organization of the Bureau of Alcohol, Tobacco, Firearms,
    and Explosives, 
    68 Fed. Reg. 4923
    , 4926 (Jan. 31, 2003). This
    delegation was accomplished under and cited to 
    28 U.S.C. § 510
    . Thus, it suffices here to observe that the ATF Director (or
    a properly designated Acting ATF Director under the FVRA)
    could have issued the bump-stock rule, as authorized under 
    28 U.S.C. § 510
    , to conclude the Attorney General was not the
    3
    only officer “required” to undertake the relevant action.
    It may be objected that asking whether a function or
    duty has actually been delegated—instead of just asking
    whether it “may be delegated”—allows the functions or duties
    that must be performed by “only” the Attorney General to
    fluctuate based on the use of delegation authorities. However,
    this is just the natural consequence of the wide discretion that
    Congress has given the Attorney General under 
    28 U.S.C. § 510
    . See also Stand Up for California! v. United States Dep’t
    of the Interior, 
    994 F.3d 616
    , 622 (D.C. Cir. 2021) (“Should
    Congress remain silent . . . the FVRA provides the Executive
    Branch with leeway to set out which functions or duties are
    exclusive and which are not.” (citing, inter alia, 
    5 U.S.C. § 3348
    (a)(2)(A))). The FVRA contemplates that an officer’s
    portfolio of exclusive functions or duties may fluctuate given
    the statute’s use a 180-day “lookback” provision to define
    regulatory “functions or duties.” 
    5 U.S.C. § 3348
    (a)(2)(B)(ii);
    see L.M.-M. v. Cuccinelli, 
    442 F. Supp. 3d 1
    , 33 (D.D.C. 2020)
    (“[T]he lookback provision contemplates that agencies may
    and will use their organic authorities to issue rules reassigning
    duties . . . .”). The absence of the lookback provision in the
    definition of statutory functions or duties means only that the
    relevant statute establishing the function or duty need not have
    been in effect sometime during the 180 days before the
    vacancy. It does not disturb the conclusion that what
    constitutes a statutory function or duty may vary based on an
    officer’s use of statutory delegation authorities.
    Ultimately, the practical result of this reading may be
    very similar to the one presented by the Government because
    department heads and other high-level officers frequently
    subdelegate all their delegable functions and duties as a matter
    of course. Nonetheless, I read the statutory text to require such
    officers to have actually delegated the authority in question
    4
    before we may conclude it is not a “function or duty” under the
    FVRA.
