    JUSTICE BOLICK, opinion of the Court:
    ¶1            In this case involving substantial consequences for alleged
    violations of campaign finance laws, we hold that due process does not
    permit the same individual to issue the initial decision finding violations
    and ordering remedies, participate personally in the prosecution of the case
    before an administrative law judge (“ALJ”), and then make the final agency
    decision that will receive only deferential judicial review.
    I.      BACKGROUND
    ¶2             On June 27, 2013, acting pursuant to A.R.S. § 16-924(A) (2011)
    repealed by 2016 Ariz. Sess. Laws, ch. 79, § 10 (2d Reg. Sess.), Arizona
    Secretary of State Ken Bennett determined that there was reasonable cause
    to believe that Attorney General Thomas Horne, Kathleen Winn, who
    served as Community Outreach Director of the Attorney General’s Office,
    and two campaign committees (collectively “Appellants”) had violated
    Arizona campaign finance laws, specifically A.R.S. §§ 16-901(14), -905, -913,
    -915, -917, and -919. The Secretary accordingly notified Solicitor General
    Robert L. Ellman, who appointed Sheila Polk as Special Arizona Attorney
    General because the Attorney General and one of his staffers were subjects
    of the notice, and “an appearance of impropriety would arise if the Arizona
    ∗Justices Ann A. Scott Timmer, Andrew W. Gould, and John R. Lopez IV
    have recused themselves from this case. Pursuant to article 6, section 3 of
    the Arizona Constitution, the Honorable Peter J. Eckerstrom, Chief Judge
    of the Arizona Court of Appeals, Division Two, the Honorable Joseph W.
    Howard, Judge of the Arizona Court of Appeals, Division Two, and the
    Honorable Timothy M. Wright, Judge of the Gila County Superior Court,
    were designated to sit in this matter.
    2
    HORNE V. POLK
    Opinion of the Court
    Attorney General’s Office investigated the alleged campaign finance
    violation.”
    ¶3            Following investigation, pursuant to A.R.S. § 16-924(A), Polk
    issued a twenty-five-page order finding that Appellants had violated
    Arizona campaign finance statutes by illegally coordinating campaign
    expenditures, exceeding contribution limits, and collecting illegal
    contributions. Polk directed Appellants to amend their campaign finance
    reports and ordered Horne and his campaign to refund contributions
    totaling approximately $397,000. The order stated that if the Appellants
    failed to take the specified actions within twenty days, “this Office will
    issue an Order Assessing a Civil Penalty pursuant to A.R.S. § 16-924(B). The
    violation of the contribution limit carries a civil penalty of three times the
    amount of money of the violation. A.R.S. § 16-905(J).”
    ¶4            Appellants requested an administrative hearing pursuant to
    A.R.S. § 16-924(A). After a three-day evidentiary hearing, the ALJ issued a
    decision finding that Polk had failed to prove illegal coordination and
    recommending that Polk vacate her compliance order.
    ¶5             Pursuant to A.R.S. § 41-1092.08(B) (2000), Polk issued her final
    administrative decision, which rejected the ALJ recommendation and
    affirmed her prior compliance order. Polk accepted all of the ALJ’s findings
    of fact and rejected in part the ALJ’s conclusions of law.
    ¶6             Appellants appealed to the Maricopa County Superior Court,
    challenging Polk’s decision and the constitutionality of Arizona’s campaign
    contribution limits. Neither side requested an evidentiary hearing. The
    court affirmed Polk’s decision, finding that substantial evidence supported
    it and rejecting challenges to the statutory scheme.
    ¶7           Appellants appealed to the court of appeals.          Polk’s
    answering brief acknowledged a fact previously unknown to Appellants:
    “Admittedly, the Yavapai County Attorney was involved with the
    prosecution of the case, by assisting with the preparation and strategy.”
    Appellants argued that Polk’s role as advocate and adjudicator violated
    their due process rights.
    ¶8            The court of appeals affirmed the superior court, concluding
    that “[b]ecause there was evidence in the record supporting Polk’s finding
    3
    HORNE V. POLK
    Opinion of the Court
    that Horne and Winn coordinated . . . , we find no abuse of discretion.”
    Horne v. Polk, 1 CA-CV 14-0837, at *5 ¶ 12 (Ariz. App. Feb. 23, 2016). The
    court rejected Appellants’ due process claim, relying on Comeau v. Arizona
    State Board of Dental Examiners, 
    196 Ariz. 102
    , 108 ¶ 26, 
    993 P.2d 1066
    , 1072
    (App. 1999) (“An agency is permitted to combine some functions of
    investigation, prosecution, and adjudication unless actual bias or partiality
    is shown.”). Horne, 1 CA-CV 14-0837, at *5–6 ¶ 13. The court concluded,
    “In this case, appellants make no showing of actual bias. Accordingly, their
    due process rights were not violated.” 
    Id.
     at *6 ¶ 13.
    ¶9             We granted review of the due process issue, which is of
    statewide importance and likely to recur. We have jurisdiction under
    article 6, section 5(3) of the Arizona Constitution and A.R.S. § 12-120.24.
    Because we consider only the constitutionality of the procedure under
    which Appellants’ statutory violations were determined, our review is de
    novo. Gallardo v. State, 
    236 Ariz. 84
    , 87 ¶ 8, 
    336 P.3d 717
    , 720 (2014).
    II.    DISCUSSION
    A. Statutory Scheme
    ¶10           Arizona’s Administrative Procedure Act (“APA”), title 41,
    chapter 6, is generally silent about how agency charges or complaints are
    initiated. In the context of campaign finance violations, § 16-924(A)
    prescribes that where there is “reasonable cause to believe that a person is
    violating any provision of this title” in connection with a statewide office,
    the “secretary of state shall notify the attorney general.” The Attorney
    General, in turn, “may serve on the person an order requiring compliance
    with that provision. The order shall state with reasonable particularity the
    nature of the violation and shall require compliance within twenty days
    from the date of issuance of the order.” Id.
    ¶11           Section 16-924(A) further provides that the alleged violator
    has twenty days to request a hearing pursuant to the APA, for which
    administrative adjudication procedures are set forth in A.R.S. § 41-1092 et
    seq. Once the ALJ issues a decision, “the head of the agency, executive
    director, board or commission may review the decision and accept, reject or
    modify it.” A.R.S. § 41-1092.08(B). Where an agency has a board or
    commission whose members are appointed by the governor, it “may review
    4
    HORNE V. POLK
    Opinion of the Court
    the decision of the agency head . . . and make the final administrative
    decision.” A.R.S. § 41-1092.08(C).
    ¶12          Ordinarily, nothing in the APA would necessitate having an
    agency head make both an initial and final legal determination. Here, the
    interplay between the campaign finance statute and the APA placed Polk
    in the position of issuing the initial order and then making the final
    determination. She also participated in the prosecution of the case before
    the ALJ. And under these circumstances, there was no board or
    commission to review Polk’s final decision. 1
    ¶13           An aggrieved party may appeal an adverse agency decision
    to the superior court, but the court’s review is deferential. Section 12-910(E)
    provides that the court “shall affirm the agency action unless after
    reviewing the administrative record and supplementing evidence
    presented at the evidentiary hearing the court concludes that the action is
    not supported by substantial evidence, is contrary to law, is arbitrary and
    capricious or is an abuse of discretion.” The court affirms the agency’s
    factual findings if they are supported by substantial evidence, “even if the
    record also supports a different conclusion.” Gaveck v. Ariz. State Bd. of
    Podiatry Exam’rs, 
    222 Ariz. 433
    , 436 ¶ 11, 
    215 P.3d 1114
    , 1117 (App. 2009).
    1 Polk notes that the federal APA contains an exception allowing an agency
    head, unlike other employees, to both participate in investigative or
    prosecuting functions and participate or advise in the agency review or
    decision. 
    5 U.S.C. § 554
    (d). Arizona’s APA contains no such exception.
    Arizona’s APA tacitly recognizes the potential for conflict arising from
    agency officials performing certain multiple roles in the administrative
    adjudication process. Section 41-1092.06(B) provides that in the context of
    informal settlement conferences, the agency must be represented by “a
    person with the authority to act on behalf of the agency,” and the “parties
    participating in the settlement conference shall waive their right to object to
    the participation of the agency representative in the final administrative
    decision.”
    5
    HORNE V. POLK
    Opinion of the Court
    B. Due Process
    ¶14           Combining prosecutorial and adjudicative functions in the
    same agency official gives rise to due process concerns. A single agency
    may investigate, prosecute, and adjudicate cases, and an agency head may
    generally supervise agency staff who are involved in those functions. See,
    e.g., Withrow v. Larkin, 
    421 U.S. 35
    , 53 (1975) (“administrative agency [can]
    investigate facts, institute proceedings, and then make the necessary
    adjudications”). However, where an agency head makes an initial
    determination of a legal violation, participates materially in prosecuting the
    case, and makes the final agency decision, the combination of functions in
    a single official violates an individual’s Fourteenth Amendment due
    process right to a neutral adjudication in appearance and reality. That due
    process violation is magnified where the agency’s final determination is
    subject only to deferential review. 2
    ¶15          The general parameters for due process are set forth in
    Mathews v. Eldridge, 
    424 U.S. 319
     (1976). There, the United States Supreme
    Court held that the constitutional sufficiency of administrative procedures
    is determined by three factors:
    First, the private interest that will be affected
    by the official action; second, the risk of an
    erroneous deprivation of such interest
    through the procedures used, and the
    probable value, if any, of additional or
    substitute procedural safeguards; and
    finally, the Government’s interest, including
    the function involved and the fiscal and
    administrative burdens that the additional
    or substitute procedural requirement would
    entail.
    2 As Appellants did not raise or argue a distinct state constitutional claim,
    we have no occasion to determine whether the due process provision in
    Arizona’s Declaration of Rights, Ariz. Const. art. 2, § 4, provides greater
    protection in this context than the Fourteenth Amendment. Cf. Garris v.
    Governing Bd. of S.C. Reinsurance Facility, 
    511 S.E.2d 48
    , 54 (S.C. 1998)
    (holding that the state constitution provides greater procedural protections
    in administrative proceedings than federal due process).
    6
    HORNE V. POLK
    Opinion of the Court
    Id. at 335.
    ¶16           In this context, where the government seeks repayment of
    substantial campaign contributions that the private parties contend were
    legal (and, indeed, constitutionally protected), due process requires a
    neutral decisionmaker. Although Appellants have not alleged actual bias,
    once an official determines that a legal violation has occurred, that official
    can be expected to develop a will to win at subsequent levels of
    adjudication. At minimum, in the context of a regulatory agency
    adjudication, a process that involves the same official as both an advocate
    and the ultimate administrative decisionmaker creates an appearance of
    potential bias. See, e.g., Botsko v. Davenport Civil Rights Comm’n, 
    774 N.W.2d 841
    , 849 (Iowa 2009) (“[T]he primary purpose of separating prosecutorial
    from adjudicative functions” in an administrative agency “is to screen the
    decisionmaker from those who have a ‘will to win.’”). On the other hand,
    barring an agency head who makes an ultimate decision from having even
    general supervisory authority over agency employees involved in the
    prosecution of a case would unduly hamper agency operations. Due
    process will be satisfied if the agency head who serves as the ultimate
    adjudicator does not also serve in an advocacy role in the agency
    proceedings.
    ¶17           The right to a neutral adjudicator has long been recognized as
    a component of a fair process. One cannot both participate in a case (for
    instance, as a prosecutor) and then decide the case. Blackstone observed
    that a judge must not rule in a cause in which he is a party, “because it is
    unreasonable that any man should determine his own quarrel.” Am. Gen.
    Ins. Co. v. Fed. Trade Comm’n, 
    589 F.2d 462
    , 463 (9th Cir. 1979) (quoting
    Blackstone, Commentaries on the Laws of England, I, 91). In In re Murchison,
    
    349 U.S. 133
    , 136 (1955), the United States Supreme Court recognized the
    due process principle that “no man can be a judge in his own case and no
    man is permitted to try cases where he has an interest in the outcome.”
    Murchison entailed a “one-man grand jury,” in which a judge acting as a
    grand jury charged two witnesses with perjury and then convicted them,
    which the Court held violated due process. 
    Id.
     at 133–34. Because the judge
    was “part of the accusatory process,” he “cannot be, in the very nature of
    things, wholly disinterested in the conviction or acquittal of those accused.”
    
    Id. at 137
    . “Fairness of course requires an absence of actual bias in the trial
    of cases. But our system of law has always endeavored to prevent even the
    probability of unfairness.” 
    Id. at 136
    ; accord Marshall v. Jerricho, Inc., 
    446 U.S. 7
    HORNE V. POLK
    Opinion of the Court
    238, 243 (1980) (“[J]ustice must satisfy the appearance of justice, and this
    stringent rule may sometimes bar trial by judges who have no actual bias
    and who would do their very best to weigh the scales of justice equally
    between contending parties.” (internal citation and quotation marks
    omitted)). The process was impermissibly tainted by the judge performing
    both prosecution and adjudication functions.
    ¶18           The Court in Withrow, 
    421 U.S. at 46
    , applied those principles
    to the administrative context. There, a state licensing board notified a
    physician that it would commence an investigative proceeding to consider
    possible violations of his medical license. 
    Id.
     at 37–39. The physician
    challenged the board’s combined investigatory and adjudicatory functions
    as a due process violation. 
    Id. at 39
    . The Court noted that although
    “situations have been identified in which experience teaches that the
    probability of actual bias on the part of the judge or decisionmaker is too
    high to be constitutionally tolerable,” the “contention that the combination
    of investigative and adjudicative functions necessarily creates an
    unconstitutional risk of bias in administrative adjudication has a much
    more difficult burden,” given “the presumption of honesty and integrity.”
    
    Id. at 47
    .
    ¶19            The Court distinguished Murchison on the basis that there
    “the judge in effect became part of the prosecution and assumed an
    adversary position,” and observed that Murchison did not stand for the
    “broad rule that the members of an administrative agency may not
    investigate the facts, institute proceedings, and then make the necessary
    adjudications.” 
    Id. at 53
    . The Court noted that an “initial charge or
    determination of probable cause and the ultimate adjudication have
    different bases and purposes,” thus the same agency may perform both
    functions. 
    Id. at 58
    . However, the Court cautioned, “[t]hat the combination
    of investigative and adjudicative functions does not, without more,
    constitute a due process violation, does not, of course, preclude a court from
    determining from the special facts and circumstances present in the case
    before it that the risk of unfairness is intolerably high.” 
    Id.
    ¶20            Here, the combination of prosecutorial and adjudicative
    functions not just in a single agency but in the same official presents
    “special facts and circumstances” creating an intolerable risk of unfairness.
    The initial determination of a legal violation here was not akin to a judge
    finding probable cause to proceed to trial and then reaching a final decision
    8
    HORNE V. POLK
    Opinion of the Court
    after an adversarial process in which the judge was not an advocate.
    Rather, under the statutory scheme, the Secretary of State made the
    probable cause finding. Polk then commenced investigation and issued a
    lengthy decision finding a legal violation and ordering compliance, which
    would have been a final determination had Appellants not appealed. In the
    subsequent ALJ proceeding, Polk admittedly “was involved with the
    prosecution of the case, by assisting with the preparation and strategy.”
    Thereafter, she issued a final administrative determination affirming her
    prior order and rejecting most of the ALJ’s conclusions of law. So we have
    here not only a single agency performing accusatory, advocacy, and
    adjudicatory functions, but the same individual performing all three
    functions. As Withrow characterized the circumstances in Murchison, “the
    judge in effect became part of the prosecution and assumed an adversary
    position.” Withrow, 
    421 U.S. at 53
    . Beyond even that, Polk was in the
    position to affirm the very determination and order that she initially issued.
    See also 
    id.
     (describing denial of due process where judge could rely on his
    own “[personal] knowledge and impression . . . that could not be tested by
    adequate cross-examination” (internal quotation marks omitted)).
    ¶21            Other decisions further inform our analysis. Concrete Pipe &
    Products of California, Inc. v. Construction Laborers Pension Trust, 
    508 U.S. 602
    (1993), pertains to pension plans, but its reasoning applies here. The federal
    statutory scheme entailed an adjudication of withdrawal liability by
    pension trustees, who have a fiduciary duty to the integrity of the pension
    plans, but the Court concluded that sufficient safeguards were present to
    ensure due process. 
    Id.
     at 619–20. The initial liability determination was
    made by the trustees, who “act only in an enforcement capacity,” 
    id. at 619
    ,
    and whose decision was reviewed by a neutral arbitrator applying a
    preponderance of the evidence standard. 
    Id. at 611
    . “Where an initial
    determination is made by a party acting in an enforcement capacity,” the
    Court ruled, “due process may be satisfied by providing for a neutral
    adjudicator to conduct a de novo review of all factual and legal issues.” 
    Id. at 618
     (internal quotation marks omitted). By contrast, “[c]learly, if the
    initial view of the facts based on the evidence derived from nonadversarial
    processes as a practical or legal matter foreclosed fair and effective
    consideration at a subsequent adversary hearing leading to ultimate
    decision, a substantial due process question would be raised.” Withrow, 
    421 U.S. at 58
    .
    9
    HORNE V. POLK
    Opinion of the Court
    ¶22           Here the initial determination was subject to de novo review
    by the ALJ, but the ALJ’s determination was not final. Rather, the initial
    decisionmaker returned to make the final decision. “Even appeal and a trial
    de novo will not cure a failure to provide a neutral and detached
    adjudicator.” Concrete Pipe, 
    508 U.S. at 618
    . The superior court review
    available from the final agency decision here falls far short of that.
    ¶23           More recently, in Williams v. Pennsylvania, 
    136 S. Ct. 1899
    ,
    1908–09 (2016), the Court found a defendant’s due process rights were
    violated when a prosecutor who approved the decision to seek the death
    penalty later served as a supreme court justice in a habeas petition arising
    from the same crime. “Of particular relevance to the instant case, the Court
    has determined that an unconstitutional potential for bias exists when the
    same person serves as both accuser and adjudicator in a case.” Id. at 1905.
    Where “a prosecutor who participates in a major adversary decision” or “a
    judge has served as an advocate for the State in the very case the court is
    now asked to adjudicate,” a serious question arises concerning whether the
    adjudicator, despite best efforts, could untether from his or her previous
    position and render a fair judgment. Id. at 1906. Here, the fact that Polk
    “had a direct, personal role in the [Appellants’] prosecution,” id., likewise
    violates due process.
    ¶24             The reasoning of the Williams dissenters also supports our
    conclusion. Chief Justice Roberts distinguished the basis for the due
    process violation in Murchison, where “the judge (sitting as grand jury)
    accused the witnesses of contempt, and then (sitting as judge) presided over
    their trial on that charge.” Id. at 1913 (Roberts, C.J., dissenting). In Williams,
    by contrast, it was “abundantly clear” that the justice “had not made up his
    mind about either the contested evidence or the legal issues under review,”
    because he had not “previously made any decision with respect to that
    evidence in his role as prosecutor.” Id. at 1914. Likewise, Justice Thomas
    observed in Williams that “[b]roadly speaking, Murchison’s rule
    constitutionalizes the early American statutes requiring disqualification
    when a single person acts as both counsel and judge in a single civil or
    criminal proceeding.” Id. at 1920 (Thomas, J., dissenting). He emphasized
    that a due process violation occurs only where the “same person . . . act[s]
    as counsel and adjudicator in the same case.” Id. at 1919 (highlighting the
    separation between the original decision to approve the request to seek the
    death penalty and the current civil proceeding regarding timeliness of a
    stay action). In this case, Polk made her views on the evidence and legal
    10
    HORNE V. POLK
    Opinion of the Court
    issues very clear in her initial twenty-five-page order, and she subsequently
    affirmed that very order in the same case after participating in the
    prosecution.
    ¶25            These cases instruct that the combination of accusatory,
    advocacy, and adjudicative roles in a single agency official violates due
    process. Other courts have followed that instruction. Synthesizing the
    cases as we have, the Iowa Supreme Court held in Botsko that the conduct
    of the civil rights commission’s director in advocating on behalf of the
    complainant and then participating in the commission’s closed
    adjudicatory proceeding violated due process. 
    774 N.W.2d at
    849–50.
    Therein, the court articulated the applicable constitutional boundaries.
    Applying Withrow, it concluded that “there is no due process violation
    based solely upon the overlapping investigatory and adjudicatory roles of
    agency actors.” 
    Id. at 849
    . “A more serious problem, however, is posed
    where the same person within an agency performs both prosecutorial and
    adjudicative roles.” Id.; see also Am. Gen., 
    589 F.2d at
    464–65 (the order “is
    infected with invalidity” because a commissioner participated as counsel in
    earlier proceedings, even though that participation may have been
    “superficial rather than substantial”); Trans World Airlines, Inc. v. Civil
    Aeronautics Bd., 
    254 F.2d 90
    , 91 (D.C. Cir. 1958) (“The fundamental
    requirements of fairness . . . require at least that one who participates in a
    case on behalf of any party, whether actively or merely formally by being
    on pleadings or briefs, take no part in the decision of that case.”); Nightlife
    Partners, Ltd. v. City of Beverly Hills, 
    133 Cal. Rptr. 2d 234
    , 248 (Cal. Ct. App.
    2003) (observing that combination of investigatory and adjudicatory
    functions is “fraught” with problems, especially where “these dual
    functions were not held by different sections of a single office, but by a single
    individual”).
    ¶26           Arizona jurisprudence is consistent with those authorities. In
    Comeau, a doctor retained by the board investigated the complaint, then
    made statements and asked questions before the administrative panel, but
    “was not on the panel and did not participate in the discussion that
    preceded the panel’s findings and recommendations.”

    156 Ariz. 369
    , 371, 
    752 P.2d 22
    , 24 (App. 1987), the court stated that “[t]he precise
    question in this case is whether simply joining investigative/prosecutorial
    and adjudicative functions results in a partial decision maker. We hold that
    it does not.” To the extent that these functions are combined in a single
    11
    HORNE V. POLK
    Opinion of the Court
    agency, we agree that the potential for bias is not intolerable; if they are
    performed by the same individual, they violate due process. Cf. Taylor v.
    Ariz. Law Enf. Merit Syst. Council, 
    152 Ariz. 200
    , 206, 
    731 P.2d 95
    , 101 (App.
    1986) (“A conflict of interest would clearly arise if the same assistant
    attorney general participated as an advocate before the council and
    simultaneously served as an advisor to the council in the same matter.”). In
    Rouse, the termination decision at issue was initiated by the staff, not the
    board that rendered the final decision; and “the board, at the time of the
    hearing, had little more than ‘mere familiarity with the facts.’” 
    156 Ariz. at 373
    , 
    752 P.2d at 26
    . Under such circumstances, the defendant still had a
    neutral adjudicator.
    ¶27            We hold that due process does not allow the same person to
    serve as an accuser, advocate, and final decisionmaker in an agency
    adjudication. This holding should not unnecessarily impede the efficient
    and effective functioning of administrative agencies. As noted, in most
    instances, agencies are free under Arizona law to generate their own
    processes regarding initiation, investigation, and prosecution of charges or
    complaints. The agency head may supervise personnel involved in such
    functions; but if she makes the final agency decision, she must be isolated
    from advocacy functions and strategic prosecutorial decisionmaking and
    must supervise personnel involved in those functions in an arms-length
    fashion. See, e.g., Lyness v. Pa. State Bd. of Med., 
    605 A.2d 1204
    , 1209, 1211
    (Pa. 1992) (“if more than one function is reposed in a single administrative
    entity, walls of division [must] be constructed which eliminate the threat or
    appearance of bias”; specifically, “placing the prosecutorial functions in a
    group of individuals, or entity, distinct from the Board which renders the
    ultimate adjudication”).
    ¶28          Although Appellants do not allege actual bias, the
    circumstances here deprived them of due process. Apparently unique in
    the context of Arizona administrative law, Arizona’s campaign finance
    statute, when joined with the APA, place a single official in the position of
    making both an initial and final determination of legal violation, with no
    opportunity for de novo review by the trial court. A quasi-judicial
    proceeding “must be attended, not only with every element of fairness but
    with the very appearance of complete fairness.” Amos Treat & Co. v. Sec. &
    Exch. Comm’n, 
    306 F.2d 260
    , 266–67 (D.C. Cir. 1962) (holding that a similar
    combination of functions violated the “basic requirement of due
    process”). Specifically, we hold that when Polk also assumed an advocacy
    12

    Opinion of the Court
    role during the ALJ proceedings, the due process guarantee prohibited her
    from then serving as the final adjudicator.
    III.    REMEDY
    ¶29           Appellants argue that because there was no “valid” decision
    by the agency head within thirty days after the ALJ decision, we should
    reinstate the ALJ decision as the “final administrative decision” pursuant
    to A.R.S. § 41-1092.08(D) (“if the head of the agency . . . does not accept,
    reject or modify the administrative law judge’s decision within thirty days,”
    it becomes “the final administrative decision”). We disagree. The agency
    head took action within the deadline.
    ¶30            Rather, Appellants are entitled to a determination by a neutral
    decisionmaker. See Williams, 136 S. Ct. at 1910; Botsko, 
    774 N.W.2d at 853
    ;
    Nightlife Partners, 
    133 Cal. Rptr. 2d at
    248–49. We therefore remand the
    matter to the current Attorney General’s Office, which does not have a
    conflict, for a final administrative decision. We express no opinion on the
    merits of the case.
    ¶31            After filing their petition for review, Appellants submitted an
    amended request for attorney fees under A.R.S. § 12-348(A)(2), which
    allows an award of fees for a party that “prevails by an adjudication on the
    merits” in a “court proceeding to review a state agency decision.” Because
    the case is remanded, any fee award would be premature as no party has
    yet “prevail[ed] by an adjudication on the merits.” Scottsdale Healthcare, Inc.
    v. Ariz. Health Care Cost Containment Syst. Admin., 
    206 Ariz. 1
    , 8 ¶ 29, 
    75 P.3d 91
    , 98 (2003) (alteration in original).
    ¶32          For the foregoing reasons, we vacate the decisions of the
    superior court and court of appeals, and remand the case to the Attorney
    General’s Office for further proceedings consistent with this opinion.
