    _______________
    JUSTICE BOLICK, opinion of the Court:
    ¶1            This case presents the question of whether the State of
    Arizona has incorporated the Portal-to-Portal Act, 
    29 U.S.C. §§ 251
    –262,
    into A.R.S. § 23-392 to govern Arizona corrections officers’ claims for
    overtime compensation for time spent in mandatory pre-shift security
    screenings. We hold that for purposes of defining “work” to determine
    overtime eligibility for law enforcement officers under § 23-392, the state
    has not incorporated the Portal-to-Portal Act into § 23-392, and state agency
    regulations purporting to do so are not legally binding. Therefore, contrary
    to the decisions of the courts below, whether the corrections officers are
    entitled to overtime should be decided as a matter of state law.
    I.
    ¶2             Plaintiffs are corrections officers (“the Officers”) who brought
    a class action against the State for compensation that was allegedly denied
    by the Arizona Department of Corrections, Rehabilitation & Reentry for
    time spent in mandatory and “extensive security screening prior to
    undertaking their assigned duties.” The complaint alleges the following
    facts: The Officers must wait in line at checkpoints for screenings before
    gaining access to prison facilities. During the screenings, the Officers must
    empty all personal possessions for a search and pass through a scanner and
    turnstile. The Officers must then wait for transportation to their assigned
    work unit, where the same screening process is repeated. After completing
    this second pre-shift screening, the Officers work a full eight-hour shift
    without breaks. The Officers allege these screenings add approximately
    thirty minutes of unpaid, mandatory time to their shifts.

    section 3, of the Arizona Constitution, Justice John Pelander (Ret.) of the

    2
    ROBERTS, ET AL. V. STATE OF ARIZONA
    Opinion of the Court
    ¶3              In the superior court, the Officers alleged that § 23-392
    requires the state to pay overtime compensation for the mandatory pre-shift
    security screenings and sought treble damages under A.R.S. § 23-355. The
    State moved to dismiss the complaint pursuant to Arizona Rule of Civil
    Procedure 12(b)(6), arguing the Fair Labor Standards Act (“FLSA”), 
    29 U.S.C. §§ 201
    –219, preempts the Officers’ state law claim. Alternatively, the
    State argued that Arizona law incorporates the Portal-to-Portal Act (“Portal
    Act”), 
    29 U.S.C. §§ 251
    –262, an amendment to the FLSA, which renders the
    Officers’ time spent in security screenings not compensable.
    ¶4            The Officers denied that the FLSA preempts state law. They
    also argued that the Portal Act has not been incorporated into Arizona law
    either by statute or regulation, that the claims are compensable under state
    law because of Arizona’s broad interpretation of “work,” and that they are
    entitled to overtime compensation even if the Portal Act applies.
    ¶5             The trial court granted the State’s motion to dismiss. The
    court concluded that federal law did not preempt the Officers’ claims, but
    that Arizona had adopted the Portal Act by implication, rendering the pre-
    shift security screening not compensable.
    ¶6           The court of appeals reversed and held that the Officers’
    claims were not preempted by the FLSA, Roberts v. State, 
    250 Ariz. 590
    , 595
    ¶ 17 (App. 2021), that the Portal Act was incorporated in Arizona through
    § 23-392 and by agency regulations, id. at 597 ¶ 27, and that the pre-shift
    screenings were compensable activities under the Portal Act, id. at 599 ¶ 37.
    ¶7            We granted review on whether, under federal law as
    incorporated in Arizona, corrections officers must be compensated for time
    spent in pre-shift security screenings. Because this issue assumed that
    Arizona law incorporated federal law, following oral argument, we invited
    further supplemental briefing on the following issues: (1) Whether, and to
    what extent, has the Portal Act been incorporated into § 23-392(A); (2) What
    does the language in § 23-392(A)(1) (“if by the person’s job classification
    overtime compensation is mandated by federal law”) refer to; and
    (3) Whether the Arizona Administrative Code regulations are binding, and,
    if so, whether the legislature properly delegated to the Director of the
    Arizona Department of Administration (“AZDOA”) the authority to
    incorporate federal law and the Code of Federal Regulations beyond what
    3
    ROBERTS, ET AL. V. STATE OF ARIZONA
    Opinion of the Court
    § 23-392(A) does. These are important questions of statewide concern. We
    have jurisdiction under article 6, section 5(3) of the Arizona Constitution.
    In the context of a Rule 12(b)(6) dismissal, the case presents pure questions
    of law, which we review de novo. See State v. Hansen, 
    215 Ariz. 287
    , 289 ¶ 6
    (2007).
    ¶8              Although the State has abandoned its argument below that
    the FLSA preempts state law regarding the definition of work and eligibility
    for overtime, it maintains (as the court of appeals held) that § 23-392(A) and
    state agency regulations incorporate the Portal Act, as well as the federal
    regulations adopted to effectuate the Portal Act. As this case presents
    complex issues of the interaction between state and federal law and the
    scope of administrative agency authority, we begin with an overview of the
    pertinent state and federal law.
    II.
    ¶9            The FLSA was adopted in 1938. Six years later, the United
    States Supreme Court addressed whether activities that are not part of the
    job, but are still required by the employer, count as compensable work
    under the FLSA. Tenn. Coal, Iron & R.R. Co. v. Muscoda Loc. No. 123, 
    321 U.S. 590
    , 593–94 (1944). The Court held that compulsory travel within a mine to
    reach the job site could qualify as work because it “is at all times under [the
    employer’s] strict control and supervision,” and “is not primarily
    undertaken for the convenience of the miners” but “is spent for the benefit
    of” the employer. 
    Id.
     at 598–99.
    ¶10           Congress narrowed the impact of Tennessee Coal in 1947 by
    adding the Portal Act to the FLSA, providing among other things that
    employers are not required to pay overtime compensation to nonexempt
    employees for “activities which are preliminary to or postliminary to [the]
    principal activity or activities” that they are employed to perform. 
    29 U.S.C. § 254
    (a)(2).
    ¶11          The leading recent case construing this provision of the Portal
    Act is Integrity Staffing Solutions, Inc. v. Busk, 
    574 U.S. 27
     (2014). In
    determining what constitutes a “principal activity” under § 254(a), the
    Supreme Court focused on whether the activity at issue is an integral and
    indispensable part of the employee’s job. Id. at 33 (deciding whether post-
    4
    ROBERTS, ET AL. V. STATE OF ARIZONA
    Opinion of the Court
    shift security screenings were compensable). Federal and state courts
    applying the Portal Act to security screenings have reached different
    conclusions concerning whether the screenings are “integral and
    indispensable” to jobs covered by the act. Compare, e.g., Aguilar v. Mgmt. &
    Training Corp., 
    948 F.3d 1270
    , 1289 (10th Cir. 2020) (holding the pre-shift
    security screenings of corrections officers compensable), with Hootselle v.
    Mo. Dep’t of Corr., 
    624 S.W.3d 123
    , 139–40 (Mo. 2021) (holding the pre-shift
    security screenings of corrections officers non-compensable).
    ¶12            In 1985, the Supreme Court ruled that the minimum wage and
    overtime provisions of the FLSA, including the Portal Act, are applicable to
    state and local government employers. Garcia v. San Antonio Metro. Transit
    Auth., 
    469 U.S. 528
    , 555–56 (1985). However, the FLSA expressly allows
    states to enact their own laws providing greater protections to workers than
    the FLSA requires. 
    29 U.S.C. § 218
    (a). 1
    ¶13            Arizona adopted § 23-392 to govern overtime compensation
    for certain law enforcement officers in 1975 with no reference to federal law.
    See 1975 Ariz. Sess. Laws ch. 51, § 1 (1st Reg. Sess.). At that time, § 23-392(A)
    read as follows:
    Any person engaged in law enforcement activities shall be
    compensated, for each hour worked in excess of forty hours
    in one work week, at the option of such employer either at a
    rate of:
    1. One and one-half times the regular rate at which he is
    employed; or
    2. One hour of compensatory time off in lieu of cash
    payment.
    ¶14            In 1984, the Arizona Court of Appeals decided Prendergast v.
    City of Tempe, 
    143 Ariz. 14
    , 20–21 (App. 1984), holding that meal periods for
    certain officers constituted compensable work. The court observed that
    § 23-392(A) did not define “work.” Id. at 17. The court also noted that 
    29 U.S.C. § 207
    (k), a provision in the FLSA that specifies overtime eligibility
    for law enforcement officers, “is irrelevant where the issue is the proper
    1
    This was the basis for the court of appeals’ holding that the FLSA does
    not preempt Arizona law in the context presented here. Roberts, 250 Ariz.
    at 594–95 ¶¶ 15–16.
    5
    ROBERTS, ET AL. V. STATE OF ARIZONA
    Opinion of the Court
    definition of work time.” Id. at 20 n.5. Rather, “[t]he proper and overriding
    test is whether the waiting time in issue is predominantly for the employer’s
    benefit or for the employee’s benefit.” Id. at 19. More specifically, a court
    “must consider what the normal duties of the employee are and whether
    the employee’s leisure is so restricted that it cannot be fairly said to be
    primarily for the employee’s benefit,” viewed in “the totality of all the
    circumstances.” Id. at 20. As the State has acknowledged here, the
    Prendergast rule is akin to the definition of work applied by the Supreme
    Court in Tennessee Coal and thus provides greater protection for workers
    than the FLSA as amended by the Portal Act.
    ¶15           In 1986, two years after Prendergast, the legislature amended
    § 23-392(A) to provide overtime compensation for “[a]ny person engaged
    in law enforcement activities” beyond forty hours per week as follows:
    1. One and one-half times the regular rate at which such
    person is employed or one and one-half hours of
    compensatory time off for each hour worked if by the
    person’s job classification overtime compensation is
    mandated by federal law.
    2. If by the person’s job classification federal law does not
    mandate overtime compensation, the person shall receive
    the regular rate of pay or compensatory leave on an hour
    for hour basis.
    1986 Ariz. Sess. Laws ch. 218, § 2 (2nd Reg. Sess.). The statute has been
    amended eight times since 1986, but the language at issue here—“if by the
    person’s job classification overtime compensation is mandated by federal
    law”—remains unchanged, and no further references to federal law have
    been added.
    ¶16            The year after this legislative change, the Attorney General
    concluded that the Arizona Legislature had not incorporated § 207(k)’s
    method of calculating overtime for corrections officers into § 23-392(A), and
    also that state law did not conflict with federal law; therefore, the forty-hour
    work week method for calculating overtime compensation specified in state
    law would prevail. Op. Ariz. Att’y Gen. I87-158 (1987). The opinion did
    not define what constitutes work for purposes of triggering § 23-392(A).
    More recently, the court of appeals also applied the forty-hour work week
    6
    ROBERTS, ET AL. V. STATE OF ARIZONA
    Opinion of the Court
    method in state law for calculating overtime compensation rather than the
    federal law method in § 207(k). Pijanowski v. Yuma County, 
    202 Ariz. 260
    (App. 2002).
    ¶17            In 2012, the legislature enacted A.R.S. § 41-743, which
    authorizes AZDOA’s Director, among other things, to “[a]dopt rules and
    procedures relating to personnel and personnel administration,”
    § 41-743(B)(3), encompassing ten specified areas, § 41-743(B)(3)(a)–(j). That
    same year, AZDOA adopted Arizona Administrative Code
    R2-5A-404(A)(1), which incorporated by reference FLSA regulations 
    29 C.F.R. §§ 553
     and 778. Part 553 covers various topics, such as the treatment
    of volunteers, the accrual and use of compensatory time off, and
    recordkeeping requirements. Part 778 covers the calculation of pay rates
    and FLSA overtime rates. AZDOA did not adopt federal regulations
    specifically implementing the Portal Act.
    ¶18           The court of appeals here, having decided that state law
    incorporates the Portal Act, applied Aguilar to the facts of this case and
    concluded that pre-shift security screenings are compensable. Roberts, 250
    Ariz. at 597–99 ¶¶ 28–37. For the reasons explained hereafter, we conclude
    that Arizona law does not incorporate the Portal Act and that whether the
    pre-shift security screenings at issue here are compensable should be
    decided as a matter of state law. We therefore need not resolve the correct
    outcome under federal law.
    III.
    A.
    ¶19            The parties agree that the meaning of the statutory
    language—“if by the person’s job classification overtime compensation is
    mandated by federal law,” § 23-392(A)(1)—is largely dispositive of the
    issues presented. The State argues that those thirteen words implicitly
    incorporate into Arizona law (or, alternatively, authorize AZDOA to
    incorporate into Arizona law through regulation) not only the entirety of
    the FLSA, including the Portal Act, but also federal implementing
    regulations, federal agency interpretative bulletins, and federal court
    jurisprudence construing federal law and regulations. That is a great deal
    of freight to load upon such a tiny statutory vessel.
    7
    ROBERTS, ET AL. V. STATE OF ARIZONA
    Opinion of the Court
    ¶20            The State effectively defeats its own argument by
    acknowledging that § 23-392(A) does not expressly incorporate the Portal
    Act into Arizona law, but rather does so implicitly. It is a foundational rule
    of statutory construction “that courts will not read into a statute something
    which is not within the manifest intention of the legislature as gathered
    from the statute itself,” and similarly the “court will not inflate, expand,
    stretch or extend a statute to matters not falling within its expressed
    provisions.” City of Phoenix v. Donofrio, 
    99 Ariz. 130
    , 133 (1965). Beyond its
    text, we will construe a statute to include only what is “necessarily implied”
    to effectuate the express manifest intention. See, e.g., Maricopa County v.
    Douglas, 
    69 Ariz. 35
    , 39 (1949).
    ¶21            This seminal rule of statutory interpretation applies here with
    special force. We will not lightly divine legislative intent to displace state
    law with sweeping and prescriptive federal statutory law and
    administrative regulations. The State argues that the statute evinces no
    intent to “diverge from the prevailing federal understanding on
    preliminary activities.” But in our system of federalism, we do not start
    with federal law and apply it unless the legislature manifests a contrary
    intent; rather, we presume that state law prevails unless we find a manifest
    intent to adopt federal law. Cf. Varela v. FCA US LLC, 
    252 Ariz. 451
    , 457
    ¶¶ 1–2 (2022) (noting there is no federal preemption under the Supremacy
    Clause of the United States Constitution when there is no conflict between
    a properly enacted state and federal law).
    ¶22           Section 23-392(A) does not expressly manifest a legislative
    intent to incorporate the entirety of the FLSA, including the Portal Act and
    implementing regulations, into Arizona law. To the contrary, the plain
    language contains a mere reference to federal law, establishing under state
    law that eligibility for overtime compensation depends on whether “by the
    person’s job classification overtime compensation is mandated by federal
    law.” § 23-392(A)(1)–(2). Contrary to the court of appeals’ far broader
    interpretation, see Roberts, 250 Ariz. at 595 ¶¶ 19–20, the unchanged
    language leading up to the reference to federal law pertains only to the rate
    and method of calculating overtime compensation and does not refer at all to
    the definition of work that would trigger such compensation.
    ¶23          For its broader view of the applicability of federal law, the
    court of appeals focused on the words from § 23-392(A) “is mandated by
    8
    ROBERTS, ET AL. V. STATE OF ARIZONA
    Opinion of the Court
    federal law.” Id. ¶ 19. But that language only amended § 23-392(A)’s
    preexisting standard for entitlement to overtime compensation. The key
    added words, in our view, are “if by the person’s job classification overtime
    compensation is mandated by federal law.” § 23-392(A) (emphasis added).
    That language does not reflect a sweeping incorporation of federal law but
    rather merely refers to a slice of federal law that addresses job classifications
    for which overtime compensation is mandated under the FLSA.
    ¶24            In the specific context of corrections officers, we agree with
    the Officers that the slice of federal law referred to in § 23-392(A) is § 207(k),
    which provides for overtime compensation under certain circumstances for
    employees of public agencies engaged in fire protection or law enforcement
    activities. Section 207(k) precisely fits the bill for what the legislature
    provided in § 23-392(A). It defines a job classification—fire protection and
    law enforcement activities including security personnel in correctional
    institutions, which corresponds to the subject matter addressed in the state
    statute—and then provides for when such personnel are entitled to
    overtime compensation. That statute confirms that qualifying corrections
    officers are entitled to overtime compensation but does not go on to define
    “work” by reference to preliminary and postliminary activities as governed
    by the Portal Act or in any other manner. Nothing in the language of
    § 23-392(A) suggests an intent to incorporate federal law beyond its
    provisions regarding which job classifications are entitled to overtime.
    ¶25             The historical sequence supports this interpretation in the
    context of overtime compensation for corrections officers. In its 1984
    decision in Prendergast, the court of appeals noted that the legislature had
    not incorporated § 207(k) into state law. See 
    143 Ariz. at
    20 n.5. Two years
    later, the legislature amended § 23-392(A) to include the reference to federal
    law. The following year, Attorney General Bob Corbin interpreted the
    statute’s revision as referencing the FLSA’s overtime compensation
    requirements, which in large part fall under § 207(k). Op. Ariz. Att’y Gen.
    I87-158 (1987); see also Pijanowski, 
    202 Ariz. at
    263 ¶ 14 (noting generally the
    modest reach of § 23-392 and observing that “modification-by-implication
    is disfavored by courts when construing statutes”). We are referred to no
    subsequent authority taking a more expansive view of § 23-392(A) until
    9
    ROBERTS, ET AL. V. STATE OF ARIZONA
    Opinion of the Court
    AZDOA adopted its regulations at issue here in 2012, twenty-six years after
    the statute was modified by adding a reference to federal law. 2
    ¶26            Nor does the overall statutory context suggest a different
    result. The limited reference to “if by the person’s job classification
    overtime compensation is mandated by federal law” in § 23-392(A) is the
    only such reference to a FLSA provision in the statute’s entirety. Repeated
    references to federal law might support the State’s incorporation argument,
    but a single reference for a specific, limited purpose strongly suggests the
    opposite. By contrast, for example, A.R.S. § 11-251(38) empowers counties
    to “establish salary and wage plans incorporating classifications and
    conditions prescribed by the federal fair labor standards act.” The
    legislature knows how to provide authority to broadly incorporate federal
    law into state law when it wishes, and it did not do so here.
    B.
    ¶27           As we conclude that the statute at issue does not incorporate
    the entirety of the FLSA, or more specifically the Portal Act, we must
    determine whether the pertinent AZDOA rules, as they relate to overtime
    compensation for law enforcement officers, are consistent with our state
    constitution’s separation of powers. We conclude they are not. At the
    outset, then, we set forth our applicable decisional framework.
    ¶28            The Arizona Constitution embraced the concept of separation
    of powers embodied in its federal counterpart. At the federal level,
    separation of powers among the three branches of government is not
    explicit but rather implicit in the constitutional structure. See, e.g., Miller v.
    French, 
    530 U.S. 327
    , 341 (2000); see also Nat’l Fed’n of Indep. Bus. v. Sebelius,
    
    567 U.S. 519
    , 707 (2012) (Scalia, J., dissenting) (“The fragmentation of power
    produced by the structure of our Government is central to liberty, and when
    we destroy it, we place liberty at peril.”).
    2
    We do not decide here that § 23-392(A) solely refers to § 207(k), for there
    may be other provisions of the FLSA that pertain to eligibility for overtime
    compensation for the job classification at issue here. See, e.g., 
    29 U.S.C. § 213
    (b)(20). Rather, we hold that § 23-392(A) does not extend to provisions
    of the FLSA that go beyond mandating overtime compensation for specific
    job classifications, such as statutes or administrative regulations defining
    “work.”
    10
    ROBERTS, ET AL. V. STATE OF ARIZONA
    Opinion of the Court
    ¶29            Separation of powers limits both the power that may be
    delegated and the method by which it is delegated from the legislative
    branch to the executive. As Justice John Marshall stated, there are some
    “important subjects, which must be entirely regulated by the legislature
    itself” and others “of less interest, in which a general provision may be
    made, and power given to [others] to fill up the details.” Wayman v.
    Southard, 
    23 U.S. 1
    , 20 (1825). “The true distinction . . . is between the
    delegation of power to make the law, which necessarily involves a
    discretion as to what it shall be, and conferring authority or discretion as to
    its execution, to be exercised under and in pursuance of the law. The first
    cannot be done; to the latter no valid objection can be made.” Marshall Field
    & Co. v. Clark, 
    143 U.S. 649
    , 693–94 (1892) (citation omitted).
    ¶30            Thus, the Supreme Court limits the exercise of legislative
    power by the executive branch on major policy questions to instances where
    a statute “plainly authorizes” executive agency action. Nat’l Fed’n of Indep.
    Bus. v. Dep’t of Lab., Occupational Safety and Health Admin. (NFIB v. OSHA),
    
    142 S. Ct. 661
    , 665 (2022), (invalidating emergency agency standards
    governing employer conduct).              This doctrine “guard[s] against
    unintentional, oblique, or otherwise unlikely delegations of the legislative
    power.” 
    Id. at 669
     (Gorsuch, J., concurring).
    ¶31            The Supreme Court recently instructed that, given this
    standard, the judicial inquiry “always begins (and often almost ends) with
    statutory interpretation. The constitutional question is whether Congress
    has supplied an intelligible principle to guide the delegee’s use of
    discretion. So the answer requires construing the . . . statute to figure out
    what task it delegates and what instructions it provides.” Gundy v. United
    States, 
    139 S. Ct. 2116
    , 2123 (2019).
    ¶32            What the United States Constitution structurally implies, the
    Arizona Constitution makes explicit. Our constitution’s framers devoted
    an entire article to separation of powers, comprised of a single command:
    “The powers of the government of the state of Arizona shall be divided into
    three separate departments, the legislative, the executive, and the judicial;
    and . . . no one of such departments shall exercise the powers properly
    belonging to either of the others.” Ariz. Const. art. 3.

    ROBERTS, ET AL. V. STATE OF ARIZONA
    Opinion of the Court
    ¶33           The article’s plain language, conjoined with the separation of
    powers principles described above, establish the pertinent analytical
    framework: Is the power to define work (i.e., activities that constitute
    compensable work) by incorporating the FLSA and, more particularly, the
    Portal Act, properly exercised by an executive agency?
    ¶34          A unilateral exercise of legislative power by an executive
    agency violates separation of powers. See, e.g., Facilitec, Inc. v. Hibbs, 
    206 Ariz. 486
    , 488 ¶ 10 (2003). By contrast, the legislature may properly
    delegate power to implement a statute so long as it plainly authorizes the
    executive agency to do so. See, e.g., 
    id.
    ¶35            The State, curiously, attaches great weight to this Court’s
    decision in State v. Williams, 
    119 Ariz. 595
    , 598 (1978), which held that “[i]t
    is perfectly legitimate for the Legislature to adopt existing federal rules,
    regulations or statutes as the law of this state.” (Emphasis added.) That is
    entirely right, but it undermines rather than supports the State’s position.
    It establishes the proposition, inherent in the separation of powers, that the
    legislature may incorporate federal law. Thus, the threshold question is
    whether the legislature plainly adopted or authorized importation of the
    relevant federal law in the statutory passage at issue. As we held in the
    previous section, the legislature did not adopt the Portal Act; hence we turn
    to whether it sufficiently authorized AZDOA to adopt the Portal Act.
    ¶36            The State argues, and the trial court held, that AZDOA
    incorporated the FLSA, including the Portal Act and implementing
    regulations, into state law through its rulemaking power. We agree that
    AZDOA regulations purport to incorporate the FLSA regulations. But we
    hold that AZDOA was not legislatively authorized to incorporate the Portal
    Act for purposes of the Officers here. Absent explicit authorization by the
    legislature, it would violate our constitution’s separation of powers for
    AZDOA to adopt the Portal Act for law enforcement officers, and no such
    authorization appears here. “[T]he scope of an agency’s power is measured
    by statute and may not be expanded by agency fiat.” Saguaro Healing LLC
    v. State, 
    249 Ariz. 362
    , 365 ¶ 19 (2020); see also Facilitec, 206 Ariz. at 488 ¶ 10
    (“An agency . . . has no powers other than those the legislature has
    delegated to it . . . . Any excursion by an administrative body beyond the
    legislative guidelines is treated as an usurpation of constitutional powers
    12
    ROBERTS, ET AL. V. STATE OF ARIZONA
    Opinion of the Court
    vested only in the major branch of government.” (alteration in original)
    (citation omitted) (internal quotation marks omitted)).
    ¶37            Section 23-392(A) makes no express delegation of power to
    anyone. As described above, it merely incorporates a portion of federal law
    into state law. It is highly unlikely that the legislature would choose to
    bestow sweeping regulatory authority upon an agency in such an oblique
    and indirect fashion. See West Virginia v. EPA, No. 20-1530, slip op. at 18
    (U.S. June 30, 2022) (“Extraordinary grants of regulatory authority are
    rarely accomplished through ‘modest words,’ ‘vague terms,’ or ‘subtle
    device[s].’” (alteration in original) (citation omitted)); NFIB v. OSHA, 142
    S. Ct. at 668 (Gorsuch, J., concurring) (opining that a “lone statutory
    subsection does not clearly authorize OSHA’s mandate”).
    ¶38           In addition to § 23-392(A), AZDOA traces its authority to
    § 41-743(B)(3), enacted in 2012, which authorizes AZDOA’s director to
    “[a]dopt rules and procedures relating to personnel and personnel
    administration.” The statute then sets forth nine specific areas of
    regulation, such as “[t]he establishment and maintenance of classification
    and compensation plans,” § 41-743(B)(3)(a), and complaint procedures for
    discrimination and harassment, § 41-743(B)(3)(f). Those are followed by a
    catch-all regulatory authorization for “[a]ny other aspects of personnel
    administration as determined by the director.” § 41-743(B)(3)(j).
    ¶39            That very same year, AZDOA adopted Ariz. Admin. Code
    R2-5A-404. Specifically, this rule provides that “FLSA Regulations 29 CFR
    553 and 778 (July 2012), are incorporated by this reference.”
    R2-5A-404(A)(1). As we evaluate the applicability of Parts 553 and 778 to
    the Officers here, we note that these Parts cover multiple matters not even
    remotely within the scope of § 23-392(A), such as treatment of volunteers
    (§ 553.100–.106); recordkeeping requirements (§ 553.50–.51); and sleep
    (§ 553.222), meal (§ 553.223), and training time (§ 553.226). Part 553 is a
    formal regulation providing guidance regarding compensable hours of
    work for law enforcement employees. See 
    29 C.F.R. § 553.221
    (b). Part 778
    is not a regulation at all but a U.S. Department of Labor interpretative
    bulletin. Curiously, AZDOA did not adopt the implementing regulations
    for the Portal Act. See 
    29 C.F.R. §§ 785
    , 790.
    13
    ROBERTS, ET AL. V. STATE OF ARIZONA
    Opinion of the Court
    ¶40             Despite the vast sweep of Parts 553 and 778, the State
    characterizes these regulations as merely an effort to “fill in the details”
    from § 23-392(A). Whatever AZDOA’s authority pursuant to § 41-743(B)(3)
    to “fill in the details” regarding overtime compensation, Ariz. Admin.
    Code R2-5A-404 cannot serve as a basis for incorporating the Portal Act into
    state law for purposes of determining overtime requirements for law
    enforcement officers, which the legislature has addressed in § 23-392. The
    decision whether to incorporate the Portal Act into Arizona law for law
    enforcement officers—thereby determining whether time spent on certain
    activities is compensable—is the very definition of the type of major policy
    question that the legislature alone may determine. As we concluded above,
    § 23-392(A) does not make such a determination. Nor can § 41-743(B)(3),
    no matter how broadly AZDOA construes it, authorize AZDOA to
    incorporate the Portal Act into our state law for purposes of determining
    overtime requirements for law enforcement officers. See, e.g., West Virginia
    v. EPA, slip op. at 31 (“A decision of such magnitude and consequence rests
    with Congress itself, or an agency acting pursuant to a clear delegation from
    that representative body.”). Indeed, even as the legislature assigned
    narrow procedural rulemaking authority to AZDOA in § 41-743(B)(3), it
    subsequently determined that in actions involving state administrative
    agencies, the courts should interpret applicable statutes “without deference
    to any previous determination that may have been made on the question
    by the agency.” A.R.S. § 12-910(F).
    ¶41             Here again, the State concedes the legislature has not
    expressly authorized AZDOA regulations but asserts that its failure to
    countermand the regulations since they were adopted amounts to “implicit
    ratification” of the regulations. The State contends that instead of the
    express delegation of legislative power that the constitution requires, an
    agency may unilaterally initiate what amounts to legislation that will stand
    unless the legislature takes positive action to erase it. This novel theory
    subverts the command that none of the branches of government “shall
    exercise the powers properly belonging to either of the others.” Ariz. Const.
    art. 3. Given that the legislative power cannot be outsourced to an executive
    agency without a statute delegating that power, see Hibbs, 206 Ariz. at 488
    ¶ 10, it is inconceivable that it may be surrendered by legislative inaction.
    ¶42            Nor do we presume, as the State suggests, that the legislature
    is aware of all of the regulations adopted by the numerous state regulatory
    14
    ROBERTS, ET AL. V. STATE OF ARIZONA
    Opinion of the Court
    agencies and tacitly approves them if it does not take contrary action. Even
    in the realm of legislative acquiescence to judicial opinions, we require
    some indication that the legislature deliberately did not change the law in
    response to a judicial opinion. See, e.g., State ex rel. Brnovich v. Ariz. Bd. of
    Regents, 
    250 Ariz. 127
    , 133 ¶ 21 (2020) (stating a general reluctance to
    presume that legislative silence equates to legislative approval).
    ¶43            We conclude that the legislature did not incorporate the
    Portal Act into § 23-392 nor expressly delegate authority to AZDOA to do
    so; and it probably could not have delegated its power given that such a
    major public policy decision is inherently legislative in nature, and the
    legislative power is inalienable. The legislature must first make the policy
    choice, then it may delegate to AZDOA the power to implement it.
    ¶44           AZDOA possesses only such powers as the legislature
    delegates to it, Facilitec, 206 Ariz. at 488 ¶ 10, and the legislature has not
    expressly granted it authority to incorporate the Portal Act for purposes of
    determining the definition of work to trigger overtime compensation
    requirements for law enforcement officers; therefore, AZDOA’s regulations
    are not binding as to whether the Officers’ mandatory pre-shift screenings
    are work for which overtime compensation is required.
    ¶45           We do not here decide, as the question is not yet before us,
    whether the Prendergast definition of work remains operative, whether
    subsequent developments may have altered it, or whether any Arizona
    statutory provisions provide guidance on the meaning of work. The trial
    court should consider these issues on remand. All we decide today is that
    the definition of work is a matter of state law, that § 23-392 does not
    incorporate the Portal Act for law enforcement officers, and that AZDOA is
    not authorized to do so.
    IV.
    ¶46          The Officers request attorney fees under A.R.S.
    § 12-341.01(A). In our discretion, reasonable attorney fees incurred in this
    Court are granted upon compliance with Arizona Rule of Civil Appellate
    Procedure 21.
    ¶47          We vacate the court of appeals’ opinion and reverse the trial
    court’s dismissal of the action. We remand the case to the trial court for
    further proceedings.
