    Evans concurred.
    COUNTY OF SANTA CLARA v. SUPERIOR COURT
    S274927
    Opinion of the Court by Guerrero, C. J.
    Hospitals and other medical providers are required by law
    to provide emergency medical services without regard to the
    patient’s insurance status or ability to pay. (42 U.S.C.
    § 1395dd(b) & (h); Health & Saf. Code, § 1317, subds. (a) & (b).)
    If the patient is enrolled in a health care service plan, by statute
    the plan must reimburse the medical provider for providing such
    emergency care under the Knox-Keene Health Care Service
    Plan Act of 1975. (Health & Saf. Code, § 1340 et seq.;
    hereinafter Knox-Keene Act; id., § 1371.4, subd. (b).) If the plan
    does not have a contract with the medical provider addressing
    the reimbursement rate, the plan must pay the provider the
    “reasonable and customary value” of the emergency care
    provided. (Cal. Code Regs., tit. 28, § 1300.71, subd. (a)(3)(B).) If
    the plan fails to pay the reasonable and customary value of such
    services, the medical provider may sue the plan directly for
    reimbursement under a quantum meruit theory. (Prospect
    Medical Group, Inc. v. Northridge Emergency Medical Group
    (2009) 
    45 Cal.4th 497
    , 506 (Prospect Medical Group); Bell v. Blue
    Cross of California (2005) 
    131 Cal.App.4th 211
    , 216–217 (Bell).)
    We granted review to decide whether a similar claim for
    reimbursement of emergency medical services may be
    maintained against a health care service plan when the plan is
    operated by a public entity, or whether the Government Claims
    1
    COUNTY OF SANTA CLARA v. SUPERIOR COURT
    Opinion of the Court by Guerrero, C. J.
    Act (Gov. Code, § 810 et seq.) immunizes a public entity from
    such a claim.
    In this case, Doctors Medical Center of Modesto, Inc., and
    Doctors Hospital of Manteca, Inc., (collectively, the Hospitals)
    provided emergency medical services to three individuals
    enrolled in a health care service plan operated by the County of
    Santa Clara (the County).            The Hospitals submitted
    reimbursement claims to the County, but the County paid only
    a portion of the claimed amounts. The Hospitals sued the
    County for the remaining amounts based on the Knox-Keene
    Act’s reimbursement provision. The trial court found that the
    Hospitals could state a quantum meruit claim against the
    County. On petition for writ of mandate, the Court of Appeal
    disagreed, holding that the County is immune from suit under
    the Government Claims Act and that no exception to immunity
    applies.
    We conclude that the Government Claims Act does not bar
    the Hospitals’ action against the County. The immunity
    provisions of the Government Claims Act are directed toward
    tort claims; they do not foreclose liability based on contract or
    the right to obtain relief other than money or damages. (Gov.
    Code, § 814.) The Hospitals have not alleged a conventional
    common law tort claim seeking money damages. Instead, they
    have alleged an implied-in-law contract claim based on the
    reimbursement provision of the Knox-Keene Act, and seek only
    to compel the County to comply with its statutory duty.
    Accordingly, the County is not immune from suit under the
    circumstances and the Hospitals’ claim may proceed.
    2
    COUNTY OF SANTA CLARA v. SUPERIOR COURT
    Opinion of the Court by Guerrero, C. J.
    I. FACTUAL AND PROCEDURAL BACKGROUND
    The County operates a health care service plan called
    Valley Health Plan, which is licensed and regulated by the
    Department of Managed Health Care (DMHC) under the Knox-
    Keene Act. (Health & Saf. Code, §§ 1341, 1345, subds. (f)(1) &
    (j), 1349.) The Knox-Keene Act applies to private and public
    entities that operate health care service plans. (Id., § 1399.5.)
    The Hospitals are licensed acute care hospitals in the Central
    Valley. The Hospitals do not have a contract with the County
    governing the rates payable for medical services provided to
    Valley Health Plan enrollees.
    As previously explained, state and federal laws require
    hospitals and other medical providers to provide emergency
    medical services regardless of the patient’s insurance status or
    ability to pay. (42 U.S.C. § 1395dd(b) & (h); Health & Saf. Code,
    § 1317, subds. (a) & (b).) If the patient is enrolled in a health
    care service plan, the Knox-Keene Act requires the plan to
    reimburse the medical provider for providing such emergency
    care. (Health & Saf. Code, § 1371.4, subd. (b).) If no contract
    exists between the plan and medical provider, the plan must pay
    the “reasonable and customary value” of the emergency care
    provided. (Cal. Code Regs., tit. 28, § 1300.71, subd. (a)(3)(B).)
    In 2016 and 2017, the Hospitals provided emergency
    medical services to three patients enrolled in Valley Health
    Plan. The Hospitals submitted to the County claims for
    reimbursement totaling approximately $144,000 for the services
    provided. The County paid the Hospitals approximately
    $28,500. The Hospitals challenged the reimbursement decisions
    by submitting written administrative appeals, which the
    County denied.
    3
    COUNTY OF SANTA CLARA v. SUPERIOR COURT
    Opinion of the Court by Guerrero, C. J.
    The Hospitals then sued the County, alleging they are
    entitled to the entire amount claimed for the emergency services
    provided to the three patients enrolled in Valley Health Plan.
    The Hospitals’ operative complaint alleged a single cause of
    action for breach of implied contract. In that complaint, the
    Hospitals alleged that the Knox-Keene Act imposes a
    mandatory duty on health care service plans to reimburse
    noncontracted providers for emergency medical services and
    that, pursuant to the Act, the Hospitals are entitled to
    reimbursement at a reasonable and customary rate for the
    services provided to the patients enrolled in Valley Health Plan.
    The Hospitals further alleged that the Knox-Keene Act and the
    DMHC’s implementing regulations gave rise to implied-in-law
    agreements between the Hospitals and the County, obligating
    the County to pay for the emergency care provided by the
    Hospitals at a reasonable and customary rate. The Hospitals
    maintained the reasonable and customary rate for the services
    provided to Valley Health Plan’s enrollees was the $144,000
    claimed by the Hospitals, rather than the $28,500 reimbursed
    by the County. They also alleged that the County’s conduct,
    including its partial reimbursement for care provided by the
    Hospitals, gave rise to implied-in-fact agreements between the
    Hospitals and the County.
    The County demurred, asserting that the Hospitals’
    implied contract claim is based on a quantum meruit theory that
    cannot be maintained against the County as a public entity. The
    trial court overruled the demurrer. It found that the Hospitals
    had stated facts sufficient to constitute a cause of action,
    “whether fashioned as a cause of action for breach of an implied
    in fact contract or one for quantum meruit.” The court resolved
    that “the public policy to promote the delivery and the quality of
    4
    COUNTY OF SANTA CLARA v. SUPERIOR COURT
    Opinion of the Court by Guerrero, C. J.
    health and medical care to the people of the State of California
    outweighs the policy to limit common law, or implied contract
    claims against public entities.” It further determined that in
    entering the regulated health care plan market, the County
    “cannot expect to rely on a public policy regarding contracts as
    to public entities so that it can be exempted from those
    regulations.”
    The County sought review through a petition for writ of
    mandate, and the Court of Appeal granted relief. (County of
    Santa Clara v. Superior Court (2022) 
    77 Cal.App.5th 1018
    (Santa Clara).) The Court of Appeal concluded that the
    Government Claims Act immunized the County from the
    Hospitals’ implied-in-law contract claim. (Santa Clara, at
    pp. 1024–1025.) The court first construed the Hospitals’ claim
    as seeking relief under a quantum meruit theory. (Ibid.) In the
    court’s view, this theory was foreclosed by the immunity
    conferred by Government Code section 815, which provides
    generally that a public entity is not liable for an injury except as
    otherwise provided by statute. (Santa Clara, at pp. 1028–1029.)
    The Court of Appeal held that Government Code section 815.6’s
    mandatory duty exception to the general rule of immunity did
    not apply because the County retains discretion in determining
    the reasonable and customary value of the Hospitals’ services to
    Valley Health Plan enrollees. (Santa Clara, at pp. 1029–1032.)
    Having also concluded that the Hospitals could not state a claim
    for breach of an implied-in-fact contract (id. at pp. 1033–1034),
    the appellate court issued a peremptory writ directing the trial
    court to vacate its order overruling the County’s demurrer and
    to enter a new order sustaining the demurrer without leave to
    amend (id. at pp. 1035–1036).
    5
    COUNTY OF SANTA CLARA v. SUPERIOR COURT
    Opinion of the Court by Guerrero, C. J.
    The Court of Appeal acknowledged that under its
    interpretation of the relevant statutes, “a provider has greater
    remedies against a private health care service plan than it does
    against a public entity health care service plan.” (Santa Clara,
    supra, 77 Cal.App.5th at p. 1032.) The court viewed that result
    as being “driven by the Legislature broadly immunizing public
    entities from common law claims and electing not to abrogate
    that immunity in the context presented here.” (Id. at p. 1032,
    fn. omitted.)
    We granted the Hospitals’ petition for review.
    II. DISCUSSION
    A. Standard of Review
    When the Court of Appeal grants a writ petition
    challenging the trial court’s order overruling a demurrer and
    directs it to sustain the demurrer, “the ordinary standards of
    demurrer review still apply.” (City of Stockton v. Superior Court
    (2007) 
    42 Cal.4th 730
    , 747 (City of Stockton).) “We give the
    complaint a reasonable interpretation, reading it as a whole and
    its parts in their context. [Citation.] Further, we treat the
    demurrer as admitting all material facts properly pleaded, but
    do not assume the truth of contentions, deductions or
    conclusions of law. [Citations.] When a demurrer is sustained,
    we determine whether the complaint states facts sufficient to
    constitute a cause of action. [Citation.] And when it is sustained
    without leave to amend, we decide whether there is a reasonable
    possibility that the defect can be cured by amendment: if it can
    be, the trial court has abused its discretion and we reverse.”
    (City of Dinuba v. County of Tulare (2007) 
    41 Cal.4th 859
    , 865
    (City of Dinuba); see also Aubry v. Tri-City Hospital Dist. (1992)
    
    2 Cal.4th 962
    , 966–967.)
    6
    COUNTY OF SANTA CLARA v. SUPERIOR COURT
    Opinion of the Court by Guerrero, C. J.
    B. The Knox-Keene Act and Implementing
    Regulations
    “ ‘The Knox-Keene Act is a comprehensive system of
    licensing and regulation under the jurisdiction of the
    Department of Managed Health Care.’ ” (Prospect Medical
    Group, 
    supra,
     45 Cal.4th at p. 504.) The Knox-Keene Act
    requires every health care service plan to be licensed by the
    DMHC. (Health & Saf. Code, § 1349.) By its terms, the Knox-
    Keene Act applies to “any private or public entity” operating a
    licensed health care service plan, subject to narrow exceptions
    not relevant here. (Id., § 1399.5; see id., § 1345, subds. (f)(1),
    (j).) The County-operated Valley Health Plan is a licensed
    health care service plan.
    The purpose of the Knox-Keene Act is “to promote the
    delivery and the quality of health and medical care to the people
    of the State of California who enroll in, or subscribe for the
    services rendered by, a health care service plan or specialized
    health care service plan.” (Health & Saf. Code, § 1342.) “The
    Legislature sought to accomplish this purpose by, among other
    things, (1) ‘transferring the financial risk of health care from
    patients to providers’ in order to ‘[h]elp . . . ensure the best
    possible health care for the public at the lowest possible cost,’
    (2) imposing ‘proper regulatory procedures’ in order to
    ‘[e]nsur[e] the financial stability’ of the system, and
    (3) establishing a system that ensures health care service plan
    ‘subscribers and enrollees receive available and accessible
    health and medical services rendered in a manner providing
    7
    COUNTY OF SANTA CLARA v. SUPERIOR COURT
    Opinion of the Court by Guerrero, C. J.
    continuity of care.’ ”1 (Centinela Freeman Emergency Medical
    Associates v. Health Net of California, Inc. (2016) 
    1 Cal.5th 994
    ,
    1005 (Centinela), quoting Gov. Code, § 1342, subds. (d), (f), &
    (g).)
    In 1994, the Legislature amended the Knox-Keene Act to
    require health care service plans to “reimburse providers for
    emergency services and care provided to its enrollees, until the
    care results in stabilization of the enrollee.” (Health & Saf.
    Code, § 1371.4, subd. (b), added by Stats. 1994, ch. 614, § 4.)
    According to one legislative analysis, the purpose of Health and
    Safety Code section 1371.4 is to eliminate “incentives for
    carriers to deny care to patients and reduce payments to
    physicians.” (Sen. Rules Com., Off. of Sen. Floor Analyses,
    Analysis of Sen. Bill No. 1832 (1993–1994 Reg. Sess.) as
    amended May 4, 1994, p. 3.) As the County acknowledges, the
    Knox-Keene Act imposes a duty on health care service plans to
    reimburse medical providers for the reasonable and customary
    value of the emergency service and care provided.
    The Knox-Keene Act assigns a significant implementation
    role to the DMHC. “The [DMHC] is charged with the
    administration and enforcement of the laws relating to health
    care service plans. [Citation.] To carry out its duties, the
    DMHC is authorized to promulgate regulations.” (Children’s
    1
    In furtherance of its intent “to ensure that the citizens of
    this state receive high-quality health care coverage in the most
    efficient and cost-effective manner possible,” in enacting the
    Knox-Keene Act the Legislature also found and declared “that it
    is in the public interest to promote various types of contracts
    between public or private payers of health care coverage, and
    institutional or professional providers of health care services.”
    (Health & Saf. Code, § 1342.6.)

    COUNTY OF SANTA CLARA v. SUPERIOR COURT
    Opinion of the Court by Guerrero, C. J.
    Hospital Central California v. Blue Cross of California (2014)
    
    226 Cal.App.4th 1260
    , 1271 (Children’s Hospital).)
    Following the Legislature’s enactment of Health and
    Safety Code section 1371.4, the DMHC promulgated
    section 1300.71 of title 28 of the California Code of Regulations
    (hereinafter Regulation 1300.71). Regulation 1300.71 sets forth
    the    reimbursement       standards     for   contracting    and
    noncontracting emergency medical providers. “The amount of
    reimbursement depends upon whether the hospital and plan
    already have a contract in place . . . .” (Long Beach Memorial
    Medical Center v. Kaiser Foundation Health Plan, Inc. (2021)
    
    71 Cal.App.5th 323
    , 329 (Long Beach Memorial).) If the hospital
    and plan already have a contract, the plan must pay the “agreed
    upon” contractual rate. (Regulation 1300.71, subd. (a)(3)(A); see
    also Long Beach Memorial, at p. 329.) If the hospital and plan
    have not entered into a contract, the plan must pay the
    “reasonable and customary value for the [emergency] health
    care services rendered.” (Regulation 1300.71, subd. (a)(3)(B);
    see also Long Beach Memorial, at p. 329.)
    Regulation 1300.71, subdivision (a)(3)(B) specifies that the
    “reasonable and customary value for the health care services”
    provided by a noncontracted emergency medical provider must
    be “based upon statistically credible information that is updated
    at least annually and takes into consideration: (i) the provider’s
    training, qualifications, and length of time in practice; (ii) the
    nature of the services provided; (iii) the fees usually charged by
    the provider; (iv) prevailing provider rates charged in the
    general geographic area in which the services were rendered;
    (v) other aspects of the economics of the medical provider’s
    9
    COUNTY OF SANTA CLARA v. SUPERIOR COURT
    Opinion of the Court by Guerrero, C. J.
    practice that are relevant; and (vi) any unusual circumstances
    in the case.”2
    These factors provide a framework for reimbursement, but
    do not necessarily resolve every dispute regarding the proper
    amount of payment. “In the final statement of reasons for
    [Regulation 1300.71], the DMHC explained that the intent was
    to establish a methodology for determining the reasonable value
    of health care services by noncontracted providers but that the
    criteria specified do not dictate a specific payment rate. Rather,
    the payor is required to calculate the appropriate
    reimbursement based on statistically credible information that
    takes the [specified] factors into consideration. If a payor fulfills
    its claims payment obligation using these criteria, the DMHC
    will consider the payor compliant with Health and Safety Code
    sections 1371 and 1371.35, i.e., the reimbursement of the claim
    will be deemed timely. ‘However, the definition is not a
    substitute for traditional forums for contract dispute resolution.
    If a provider disputes the payor’s calculation of the fair and
    reasonable value of the health care services he has rendered, the
    2
    “In defining ‘reasonable and customary value,’ the DMHC
    incorporated language from Gould v. Workers’ Comp. Appeals
    Bd. (1992) 
    4 Cal.App.4th 1059
    .” (Children’s Hospital, 
    supra,
    226 Cal.App.4th at p. 1272.) In Gould, the Court of Appeal held
    that in deciding whether a medical provider’s fees for treating
    employment-related injuries was reasonable, the Workers’
    Compensation Appeals Board “may consider evidence regarding
    the medical provider’s training, qualifications, and length of
    time in practice; the nature of the services provided; the fees
    usually charged by the medical provider; the fees usually
    charged in the general geographical area in which the services
    were rendered; other aspects of the economics of the medical
    provider’s practice that are relevant; and any unusual
    circumstances in the case.” (Gould, at p. 1071, fn. omitted.)
    10
    COUNTY OF SANTA CLARA v. SUPERIOR COURT
    Opinion of the Court by Guerrero, C. J.
    provider is free to seek resolution of that dispute in a court of
    law or through any other available civil remedy.’ ” (Children’s
    Hospital, 
    supra,
     226 Cal.App.4th at p. 1273.)
    In this respect, Children’s Hospital further explained that
    in adopting Regulation 1300.71, subdivision (a)(3)(B), “the
    DMHC intended that reasonable value be based on the concept
    of quantum meruit and that value disputes be resolved by the
    courts. In fact, the DMHC has acknowledged that, unlike the
    courts, it ‘ “lacks the authority to set specific reimbursement
    rates under theories of quantum meruit and the jurisdiction to
    enforce a reimbursement determination on both the provider
    and the health plan.” ’ ”          (Children’s Hospital, supra,
    226 Cal.App.4th at p. 1273.) In a letter brief filed in Bell, the
    DMHC elaborated on the limits of its authority.3 It explained
    that although it may direct a health care service plan to modify
    its reimbursement methodology if it finds a demonstrable and
    unjust payment pattern (Health & Saf. Code, § 1371.37;
    Regulation 1300.71), “this authority is not equivalent to
    rendering a judicial determination between two parties
    disputing over what constitutes the reasonable and customary
    value of a specific physician’s services. [¶] . . . [¶] . . . [T]he
    Knox-Keene Act does not authorize the [DMHC] to set specific
    reimbursement levels or to exercise jurisdiction over providers
    by adjudicating individual payment disputes that arise between
    providers and health plans. Should the [DMHC] attempt to
    adjudicate such claims, its decisions would not be binding upon
    3
    Prior to oral argument, we granted Santa Clara’s request
    to take judicial notice of the DMHC’s amicus letter brief filed in
    the Court of Appeal in Bell, supra, 
    131 Cal.App.4th 211
    .

    COUNTY OF SANTA CLARA v. SUPERIOR COURT
    Opinion of the Court by Guerrero, C. J.
    the individual providers or upon health plans that contest the
    [DMHC]’s authority to set reimbursement rates.”
    Thus, as this court and others have previously observed,
    the Knox-Keene Act’s statutory and regulatory scheme
    contemplates that private actions under a quantum meruit
    theory may be used to recoup appropriate reimbursement for
    services rendered.4 (E.g., Prospect Medical Group, 
    supra,
    45 Cal.4th at pp. 505–507; Long Beach Memorial, supra,
    71 Cal.App.5th at p. 329; Bell, supra, 131 Cal.App.4th at
    pp. 216–217; California Emergency Physicians Medical Group v.

    (California Emergency Physicians); Health & Saf. Code,
    § 1371.37, subd. (f) [specifying that the DMHC’s imposition of
    sanctions for unfair payment patterns “shall not preclude,
    suspend, affect, or impact any other duty, right, responsibility,
    or obligation under a statute or under a contract between a

    Although we assume for purposes of this case that the
    Knox-Keene Act does not create a private right of action for
    violations of its provisions, we reaffirm that the absence of a
    private right of action does not foreclose the availability of other
    remedies, such as an action for quantum meruit, brought by
    medical providers. (See Lu v. Hawaiian Gardens Casino, Inc.
    (2010) 
    50 Cal.4th 592
    , 603 [determination that statute “does not
    provide a private cause of action does not necessarily foreclose
    the availability of other remedies”]; Coast Plaza Doctors
    Hospital v. UHP Healthcare (2002) 
    105 Cal.App.4th 693
    , 706
    [concluding that the DMHC does not have exclusive jurisdiction
    to enforce the Knox-Keene Act, and that medical providers may
    bring common law and other statutory causes of action]; see id.
    at p. 707 [“The Knox-Keene Act itself contemplates that a
    provider may have a cause of action under a statutory or
    common law theory”].)
    12
    COUNTY OF SANTA CLARA v. SUPERIOR COURT
    Opinion of the Court by Guerrero, C. J.
    and regulatory scheme in mind, we next consider the scope of
    governmental immunity under the Government Claims Act and
    whether it bars the Hospitals’ implied-in-law contract claim
    based on section 1371.4 of the Knox-Keene Act.
    C. The Government Claims Act Does Not Bar the
    Hospitals’ Implied-In-Law Contract Cause of
    Action Based on the Knox-Keene Act
    Government Code section 815 sets forth the general rule
    of immunity for public entities under the Government Claims
    Act. Government Code section 815 provides that “[e]xcept as
    otherwise provided by statute” “[a] public entity is not liable for
    an injury, whether such injury arises out of an act or omission
    of the public entity or any other person.” However, another
    provision within the Government Claims Act, Government Code
    section 814, makes clear that “[n]othing in this part affects
    liability based on contract or the right to obtain relief other than
    money or damages against a public entity or public employee.”
    The legislative committee comments to Government Code
    section 815 explain that “[t]his section abolishes all common law
    or judicially declared forms of liability for public entities, except
    for such liability as may be required by the state or federal
    constitution, e.g., inverse condemnation. In the absence of a
    constitutional requirement, public entities may be held liable
    only if a statute (not including a charter provision, ordinance or
    regulation) is found declaring them to be liable.” (Legis. Com.
    com., 32 pt. 1, West’s Ann. Gov. Code (2012 ed.) foll. § 815,
    pp. 215–216.) The comments also state: “Because of the
    limitations contained in Section 814, which declares that this

    to obtain specific relief against public entities and employees,

    law governmental liability for damages arising out of torts. The
    use of the word ‘tort’ has been avoided, however, to prevent the
    imposition of liability by the courts by reclassifying the act
    causing the injury.” (Id. at p. 216.) Likewise, the legislative
    committee comments to Government Code section 814 declare
    that “[t]he various provisions of this part determine only
    whether a public entity or public employee is liable for money or
    damages. These provisions do not create any right to any other
    type of relief, nor do they have any effect on any other type of
    relief that may be available against a public entity or public
    employee.” (Legis. Com. com., 32 pt. 1, West’s Ann. Gov. Code
    (2012 ed.) foll. § 814, p. 208.)
    The County argues that the immunity conferred under
    Government Code section 815 extends to the Hospitals’
    quantum meruit claim. The County takes the position that the
    Government Claims Act’s immunity provisions apply broadly to
    all “non-contractual” claims for money or damages, and it
    maintains that the Hospitals’ quantum meruit claim does not
    sound in contract. The Hospitals counter that the Government
    Claims Act applies only to torts, and thus it does not bar their
    cause of action involving what they characterize as an implied-
    in-law contract. They also maintain that their claim for
    reimbursement, as mandated by statute, is not a claim for
    “money or damages” under Government Code section 814.5
    5
    The County urges us to not consider various arguments
    made by the Hospitals regarding the limited nature of the
    Government Claims Act because they did not raise these specific
    contentions below. The County cites California Rules of Court,
    rule 8.500(c)(1), which provides that “[a]s a policy matter, on
    petition for review the Supreme Court normally will not
    14
    COUNTY OF SANTA CLARA v. SUPERIOR COURT
    Opinion of the Court by Guerrero, C. J.
    The impetus for the Government Claims Act and its
    general aims are well understood. In Quigley v. Garden Valley
    Fire Protection Dist. (2019) 
    7 Cal.5th 798
    , 803 (Quigley), we
    recounted that “[f]or many decades before the Act, tort liability
    for public entity defendants was barred by a common law rule of
    governmental immunity. Over time, however, the common law
    rule became ‘riddled with exceptions,’ both legislative and judge
    made, and in 1961 this court abolished the rule altogether.
    (Muskopf v. Corning Hospital Dist. (1961) 
    55 Cal.2d 211
    , 216
    (Muskopf).)      In response to Muskopf, the Legislature
    temporarily suspended the decision’s effect [citation] and
    directed the California Law Revision Commission to complete a
    study of the issue it had begun some years earlier [citations].
    The end product of the commission’s study was a series of
    recommendations [citation], on which the Legislature relied in
    enacting the [Government Claims Act].” (Quigley, at p. 803,
    fn. omitted.) “The basic architecture of the [Government Claims
    Act] is encapsulated in Government Code section 815.
    consider an issue that the petitioner failed to timely raise in the
    Court of Appeal.” However, the Hospitals included these
    arguments in their petition for review, and we “may decide any
    issues that are raised or fairly included in the petition or
    answer.” (Id., rule 8.516(b)(1).) Moreover, “[i]n a number of
    cases, this court has decided issues raised for the first time
    before us, where those issues were pure questions of law, not
    turning upon disputed facts, and were pertinent to a proper
    disposition of the cause or involved matters of particular public
    importance.”     (People v. Superior Court (Ghilotti) (2002)
    
    27 Cal.4th 888
    , 901, fn. 5; see also Today’s Fresh Start, Inc. v.

    57 Cal.4th 197
    ,
    215 [“we have discretion to consider on appeal purely legal
    issues raised in a petition for review or answer”].) Assuming
    that the Hospitals did not specifically raise these arguments in
    the courts below, we exercise our discretion to address them.
    15
    COUNTY OF SANTA CLARA v. SUPERIOR COURT
    Opinion of the Court by Guerrero, C. J.
    Subdivision (a) of that section makes clear that under the [Act],
    there is no such thing as common law tort liability for public
    entities; a public entity is not liable for an injury ‘[e]xcept as
    otherwise provided by statute.’ ” (Ibid.)
    This history has informed our repeated characterization of
    the Government Claims Act as concerned with common law
    torts, as opposed to different claims.6 The Government Claims
    Act, we have said, was designed to “govern[] . . . liabilities and
    immunities of public entities and public employees for torts.”
    (Quigley, 
    supra,
     7 Cal.5th at p. 803, italics added; see also Kizer
    v. County of San Mateo (1991) 
    53 Cal.3d 139
    , 145 (Kizer)
    [explaining that the Government Claims Act “is a
    comprehensive statutory scheme that sets forth the liabilities
    and immunities of public entities and public employees for
    torts”], overruled on another ground in Los Angeles Unified
    School District v. Superior Court (2023) 
    14 Cal.5th 758
    .)
    In Kizer, 
    supra,
     
    53 Cal.3d 139
    , we rejected an expansive
    interpretation of the Tort Claims Act, as the statute was then
    called, similar to the one advanced by the County in this case.
    The defendant in Kizer, also a county, was licensed to operate a
    long-term health care facility but failed to comply with the
    statutory scheme regulating such facilities. (Kizer, at pp. 141–
    6
    Indeed, when first enacted, and for decades afterward,
    “the statute was known as the Tort Claims Act.” (Quigley,
    supra, 7 Cal.5th at p. 803, fn. 1.) In 2012, the Legislature
    renamed the statute the Government Claims Act (Stats. 2012,
    ch. 759), a title that accounts for the fact that its claims
    presentation requirements, included in part 3 of the Act, sweep
    more broadly than do part 2’s provisions regarding public entity
    liability and immunity. (Quigley, at p. 803, fn. 1; see City of
    Stockton, 
    supra,
     42 Cal.4th at pp. 740–742.)
    16
    COUNTY OF SANTA CLARA v. SUPERIOR COURT
    Opinion of the Court by Guerrero, C. J.
    144.) The county asserted that the Act shielded it from statutory
    penalties sought by the state. (Kizer, at p. 144.) We held
    otherwise, explaining: “The County argues that the Legislature
    intended to cover a wider range of liabilities than torts. The
    County points to the comment to Government Code section 815,
    emphasizing this passage: ‘the use of the word “tort” has been
    avoided . . . to prevent the imposition of liability by the courts by
    reclassifying the act causing the injury.’ The comment,
    however, also states that ‘the practical effect of this section is to
    eliminate any common law governmental liability for damages
    arising out of torts.’ [Citation.] Moreover, the introductory
    comment to the Tort Claims Act as a whole states that ‘a statute
    should be enacted providing that public entities are not liable
    for torts unless they are declared to be liable by an enactment.’
    [Citation.] Clearly, the emphasis of the Tort Claims Act is on
    torts.” (Kizer, at p. 145, fn. 4.) Read against the background of
    general tort law, we concluded that the Act was intended to limit
    the state’s “exposure to liability for actual compensatory
    damages in tort cases.” (Kizer, at p. 146.)
    More recently, in City of Dinuba, supra, 
    41 Cal.4th 859
    ,
    we rejected the County of Tulare’s claim that the Government
    Claims Act immunized it from an action to recover misallocated
    tax revenue, which the county was obligated by statute to
    allocate and distribute. (City of Dinuba, at pp. 865–868.) We
    held that the Government Claims Act did not foreclose the
    plaintiffs’ claim for reimbursement, both because the injury
    alleged did not come within the Act’s definition of “ ‘injury’ ”
    (City of Dinuba, at p. 867, citing Gov. Code, § 810.8), and
    because the plaintiffs were not seeking money damages (City of
    Dinuba, at p. 867). Regarding the latter ground, we explained:
    “[T]he immunity provisions of the Act are only concerned with
    17
    COUNTY OF SANTA CLARA v. SUPERIOR COURT
    Opinion of the Court by Guerrero, C. J.
    shielding public entities from having to pay money damages for
    torts. [Citation.] Section 814 explicitly provides that liability
    based on contract or the right to obtain relief other than money
    damages is unaffected by the Act. Plaintiffs do not seek
    damages; they seek only to compel defendants to perform their
    express statutory duty. While compliance with the duty may
    result in the payment of money, that is distinct from seeking
    damages.” (Ibid.) Having also determined that “mandamus
    provides an appropriate remedy for defendants’ failure to
    comply with their statutory duty” (id. at p. 868), we declined to
    resolve “whether plaintiffs could have maintained claims for
    quasi-contract or constructive trust had mandamus not been
    available” (id. at p. 870).
    The Courts of Appeal have likewise recognized that the
    Government Claims Act’s immunity and liability provisions are
    aimed at common law tort claims for money damages. (See, e.g.,
    Schooler v. State of California (2000) 
    85 Cal.App.4th 1004
    , 1013
    [“Courts have determined that under section 814, Government
    Code immunities extend only to tort actions that seek money
    damages”]; Cavey v. Tualla (2021) 
    69 Cal.App.5th 310
    , 326
    [“The Government Claims Act was enacted in 1963 to provide a
    comprehensive statutory scheme governing the liabilities and
    immunities of public entities and public employees for torts”];
    Nealy v. County of Orange (2020) 
    54 Cal.App.5th 594
    , 601
    [same].) In various circumstances, the appellate courts have
    construed equitable claims for payment related to statutory
    obligations as not being subject to the Government Claims Act.
    (See, e.g., Piccinini v. California Emergency Management
    Agency (2014) 
    226 Cal.App.4th 685
    , 689 [promissory estoppel

    public entity for the misaward of a public contract under a
    theory of promissory estoppel; court could use “promissory
    estoppel primarily to further certain public policies by creating
    a damages remedy for a public entity’s statutory violation”].)
    In short, our case law and well-reasoned holdings from the
    Courts of Appeal confirm that the Government Claims Act is
    concerned with shielding public entities from tort claims seeking
    money damages, and not with every conceivable claim that
    might be pressed against a public entity.
    Notwithstanding this authority demonstrating that the
    Legislature was primarily focused on common law tort claims
    when it enacted the Act’s immunity and liability provisions, the
    County maintains that the Government Claims Act forecloses
    the Hospitals’ quantum meruit cause of action. The County
    argues, first, that the Hospitals’ compliance with the
    Government Claims Act’s claims presentation requirements
    establishes that they seek money or damages covered by the
    Act’s immunity provisions. We reject this argument. As noted
    in footnote 6, ante, the claims presentation requirements of the
    Government Claims Act are broader in scope than the Act’s
    19
    COUNTY OF SANTA CLARA v. SUPERIOR COURT
    Opinion of the Court by Guerrero, C. J.
    public entity immunity or liability provisions. (City of Stockton,
    
    supra,
     42 Cal.4th at pp. 738, 741 [a public entity is not immune
    from liability on its contracts, but the claims presentation
    requirements nonetheless apply to such contract actions]; see
    Hart v. County of Alameda (1999) 
    76 Cal.App.4th 766
    , 779 [“the
    Legislature intended the claims presentation statutes to broadly
    apply to ‘ “ ‘all forms of monetary demands . . . ,’ ” ’ and the
    earlier conclusion that the Claims Act was limited to tort claims
    was based on the government immunity statutes, which contain
    different statutory language”].)7        The Hospitals’ mere
    compliance with the Act’s claims presentation requirements
    does not control or determine the nature of their action.
    The County also argues that the Government Claims Act’s
    immunity provisions apply broadly to any common law claim,
    other than a claim alleging an express contract, seeking “money
    or damages” (Gov. Code, § 814). It asserts that “to the extent
    the Legislature considered the existence of a quantum meruit
    claim brought against [a public entity] when drafting the
    Government Claims Act, it would have understood such a claim
    as a non-contractual action for money or damages, and thus a
    ‘tort.’ ” Yet, even if we were to assume that the Government
    Claims Act’s immunity provisions might apply to some claims
    that are not obviously tortious in nature, the contours of which
    we need not delve into here, we are confident that the Act does
    7
    The County’s reliance on Canova v. Trustees of Imperial
    Irrigation Dist. Employee Pension Plan (2007) 
    150 Cal.App.4th 1487
    , 1493, is equally unpersuasive because that case also
    concerns the Government Claims Act’s claims presentation
    requirements, and not its immunity and liability provisions.
    20
    COUNTY OF SANTA CLARA v. SUPERIOR COURT
    Opinion of the Court by Guerrero, C. J.
    not immunize the County from the Hospitals’ quantum meruit
    claim to enforce a statutory duty of reimbursement.
    “Quantum meruit refers to the well-established principle
    that ‘the law implies a promise to pay for services performed
    under circumstances disclosing that they were not gratuitously
    rendered.’ [Citation.] To recover in quantum meruit, a party
    need not prove the existence of a contract [citations], but it must
    show the circumstances were such that ‘the services were
    rendered under some understanding or expectation of both
    parties that compensation therefor was to be made.’ ”
    (Huskinson & Brown v. Wolf (2004) 
    32 Cal.4th 453
    , 458
    (Huskinson & Brown).) The doctrine manifests “ ‘ “a general
    principle, underlying various legal doctrines and remedies, that
    one person should not be permitted unjustly to enrich himself at
    the expense of another, but should be required to make
    restitution of or for property or benefits received, retained, or
    appropriated, where it is just and equitable that such restitution
    be made, where such action involves no violation or frustration
    of law or opposition to public policy, either directly or
    indirectly.” ’ ” (Dinosaur Development, Inc. v. White (1989)
    
    216 Cal.App.3d 1310
    , 1315; see Rest., Restitution, §§ 113, 114.)
    “In interpreting statutes dealing with claims ‘arising upon
    contract’ to cover quasi-contractual obligations, the term ‘quasi-
    contract’ is sometimes applied to statutory obligations that
    cannot be accurately classified as strictly contractual or subject
    to tort liability.” (1 Witkin, Summary of Cal. Law (11th ed.
    2017) Contracts, § 104, pp. 148–149.)
    In this respect, the Court of Appeal below applied a rubric
    whereby “[w]hether an action sounds in contract or tort for
    purposes of governmental immunity ‘ “ ‘depends upon the
    nature of the right sued upon, not the form of the pleading or
    21
    COUNTY OF SANTA CLARA v. SUPERIOR COURT
    Opinion of the Court by Guerrero, C. J.
    relief demanded. If based on breach of promise it is contractual;
    if based on breach of a noncontractual duty it is tortious.’ ” ’ ”
    (Santa Clara, supra, 77 Cal.App.5th at p. 1033, quoting Roe v.
    State of California (2001) 
    94 Cal.App.4th 64
    , 69.) Although this
    distinguishing principle may be useful in other contexts, we
    regard it as unhelpful in ascertaining the nature of the
    Hospitals’ quantum meruit claim, which is premised on a theory
    of a promise implied in law (see Huskinson & Brown, 
    supra,
    32 Cal.4th at p. 458), and, more specifically, on a
    reimbursement duty imposed by statute. Instead, we draw
    support from our decisions in City of Dinuba and Kizer, which
    share sufficient commonalities with this matter to lead us to
    conclude that the Government Claims Act does not immunize
    the County from the Hospitals’ action.
    In City of Dinuba, the plaintiffs sought to recover
    misallocated tax revenue, which the defendant county was
    obligated by statute to distribute to the plaintiffs. (City of
    Dinuba, supra, 41 Cal.4th at p. 863.) We held that the
    Government Claims Act’s immunity provisions did not apply to
    the plaintiffs’ action, in part because we determined that the
    plaintiffs did not seek money damages. (City of Dinuba, at
    p. 867, citing Gov. Code, § 814.) We concluded that the plaintiffs
    instead sought “only to compel defendants to perform their
    express statutory duty. While compliance with the duty may
    result in the payment of money, that is distinct from seeking
    damages.” (City of Dinuba, at p. 867.)
    Here too, the Hospitals do not seek money damages. They
    seek to compel the County to comply with its mandatory duty
    under the Knox-Keene Act and its implementing regulations to
    reimburse the Hospitals for the reasonable and customary value
    of their emergency services and care. Although some differences
    22
    COUNTY OF SANTA CLARA v. SUPERIOR COURT
    Opinion of the Court by Guerrero, C. J.
    exist between the claims in City of Dinuba and this matter, the
    nature of the right sued upon — the statutory right to receive
    funds — is analogous. As we noted in City of Dinuba,
    “Section 814 explicitly provides that liability based on contract
    or the right to obtain relief other than money damages is
    unaffected by the Act.” (City of Dinuba, supra, 41 Cal.4th at
    p. 867.) This provision applies with equal force here. (See Kizer,
    
    supra,
     53 Cal.3d at p. 146 [Government Claims Act was
    intended to limit government “exposure to liability for actual
    compensatory damages in tort cases”]; Utility Audit, supra,
    112 Cal.App.4th at p. 958 [“A claim for refund of overcharges,
    without more, appears to be based upon breach of a contractual
    duty”]; see also Bowen v. Massachusetts (1988) 
    487 U.S. 879
    , 893
    [action for reimbursement of withheld Medicaid payments
    federal agency was statutorily obligated to provide is not an
    action for “ ‘money damages’ as that term is used in the
    [Administrative Procedure Act]”].)8
    Certain aspects of our decision in Kizer are also on point.
    In determining that the state’s enforcement action in Kizer did
    not fall within the purview of the Government Claims Act’s
    immunity provisions, we first emphasized that this particular
    action “lies outside the perimeters of a tort action and therefore
    does not readily lend itself to a liability analysis based on tort
    8
    As previously noted, in City of Dinuba, supra, 41 Cal.4th
    at page 868, we concluded that the defendants’ failure to comply
    with their statutory duty gave rise to mandamus relief. The fact
    that an additional form of mandamus relief was appropriate in
    City of Dinuba does not alter our view regarding the nature of
    the underlying claims in this case. As in City of Dinuba, we are
    persuaded that the action in this case seeks relief other than
    money damages.
    23
    COUNTY OF SANTA CLARA v. SUPERIOR COURT
    Opinion of the Court by Guerrero, C. J.
    principles.” (Kizer, 
    supra,
     53 Cal.3d at p. 146.) Based on the
    detailed statutory scheme regulating long-term health care
    facilities, we concluded that “[g]ranting immunity to public
    entities from the [statutory] penalties would be contrary to the
    intent of the Legislature to provide a citation system for the
    imposition of prompt and effective civil sanctions against long-
    term health care facilities in violation of the laws and
    regulations of this state.” (Ibid.) We also emphasized that
    “nothing in the statutory scheme . . . suggests that state and
    other government health facilities should be treated differently
    than private facilities” (id. at p. 148), and we perceived “ ‘no
    significant public policy reason to exempt a state licensed
    health-care facility from liability for penalties under the [Act]
    simply because it is operated by a public rather than a private
    entity’ ” (ibid.).
    Like the defendant in Kizer, the County is subject to the
    terms of the Knox-Keene Act, a detailed regulatory scheme,
    because it chose to enter the health care plan market and
    operate a licensed health care service plan. As has been
    discussed, the Knox-Keene Act applies to “any private or public
    entity” operating a licensed health care service plan, subject to
    narrow exceptions not applicable here. (Health & Saf. Code,
    § 1399.5; see id., § 1345, subds. (f)(1), (j).) The statutory and
    regulatory scheme explicitly provides for mandatory
    reimbursement (id., § 1371.4, subd. (b); Centinela, 
    supra,
    1 Cal.5th at p. 1001; Prospect Medical Group, 
    supra,
     45 Cal.4th
    at pp. 501, 504, 507; Long Beach Memorial, supra,
    71 Cal.App.5th at p. 329; Bell, supra, 131 Cal.App.4th at p. 216;
    California Emergency Physicians, supra, 111 Cal.App.4th at
    p. 1131) and specifies, in general but comprehensive terms, how
    to calculate that reimbursement amount (Regulation 1300.71).
    24
    COUNTY OF SANTA CLARA v. SUPERIOR COURT
    Opinion of the Court by Guerrero, C. J.
    (See Long Beach Memorial, at p. 338 [“The underlying duty to
    repay [emergency medical services] is established by the Knox-
    Keene Act, . . . while the amount of repayment is governed
    either by contract (when the parties have a preexisting contract)
    or by the quasi-contractual remedy of quantum meruit (when
    they do not)”].)
    As in Kizer, we see “nothing in the statutory scheme that
    suggests that state and other government health [care service
    plans] should be treated differently than private [health plans],”
    nor do we perceive any “ ‘significant public policy reason to
    exempt a state licensed [health care service plan] from
    liability . . . under the [Knox-Keene] Act simply because it is
    operated by a public rather than a private entity . . . .” (Kizer,
    
    supra,
     53 Cal.3d at p. 148.) To the contrary, disallowing such a
    claim against the County would undermine an important
    purpose of the Knox-Keene Act, as we and others have
    interpreted it. As the DMHC, appearing as amicus curiae in
    Bell,     emphasized,      “ ‘The  prompt     and    appropriate
    reimbursement of emergency providers ensures the continued
    financial viability of California’s health care delivery
    system. . . . [D]enying emergency providers judicial recourse to
    challenge the fairness of a health plan’s reimbursement
    determination[] allows a health plan to systematically underpay
    California’s safety-net providers . . . .’ ”       (Bell, supra,
    131 Cal.App.4th at p. 218.) The Legislature’s purpose in
    enacting section 1371.4 of the Knox-Keene Act would be ill-
    served by a rule immunizing public entities that operate
    licensed health care service plans from emergency services
    25
    COUNTY OF SANTA CLARA v. SUPERIOR COURT
    Opinion of the Court by Guerrero, C. J.
    reimbursement claims, thus reintroducing the very risk of
    systematic underpayment the Legislature sought to eliminate.9
    Moreover, and as noted ante, the DMHC “ ‘lacks the
    authority to set specific reimbursement rates under theories of
    quantum meruit and the jurisdiction to enforce a
    reimbursement determination on both the provider and the
    health plan. Because the [DMHC] cannot provide an adequate
    forum, health care providers must be allowed to maintain a
    cause of action in court to resolve individual claims-payment
    disputes over the reasonable value of their services.’ ” (Bell,
    supra, 131 Cal.App.4th at p. 218.)        Under the County’s
    interpretation of the Government Claims Act, emergency
    medical providers without a contract in place with a health care
    service plan could resolve individual disputes over
    reimbursement only if that plan were operated by a private,
    rather than public, entity. Again, we find this proposed two-tier
    system “contradicts the very public policy that the Legislature
    sought to implement” with the reimbursement provision of the
    Knox-Keene Act.10 (Kizer, supra, 53 Cal.3d at p. 148.)
    9
    Indeed, more than a decade after the Legislature enacted
    the Knox-Keene Act’s reimbursement provision, former
    Governor Arnold Schwarzenegger issued an executive order
    reaffirming the public policy in favor of requiring all health care
    service plans to reimburse emergency medical providers at the
    reasonable and customary value. (Governor’s Exec. Order No.
    S-13-06 (July 25, 2006).)
    10
    Given the DMHC’s express acknowledgment that it
    cannot set specific reimbursement levels or adjudicate
    individual payment disputes between health plans and
    emergency physicians, we also reject the County’s argument
    that a quantum meruit action is unnecessary because the Knox-
    26
    COUNTY OF SANTA CLARA v. SUPERIOR COURT
    Opinion of the Court by Guerrero, C. J.
    We conclude from the foregoing that allowing the
    Hospitals to proceed with their quantum meruit claim premised
    on the County’s statutory obligation of reimbursement violates
    neither the letter nor the spirit of the Government Claims Act.
    It also furthers a fundamental purpose of the Knox-Keene Act,
    protecting the continued financial viability of California’s health
    care delivery system, by ensuring that all emergency medical
    providers have an adequate remedy if there are disputes over
    payment, either by alleging breach of contract (if there is a
    contract between the provider and health care plan), or by
    raising a quantum meruit claim based on the Knox-Keene Act’s
    reimbursement obligation (if there is no contract in place).
    In arguing that the Government Claims Act’s immunity
    provisions extend to quantum meruit claims, the County cites
    three decisions by this court predating the Act in which we
    discussed the availability of quantum meruit claims against
    government entities: Miller v. McKinnon (1942) 
    20 Cal.2d 83
    (Miller), Los Angeles Dredging Co. v. Long Beach (1930) 
    210 Cal. 348
     (Los Angeles Dredging Co.), and Zottman v. San Francisco
    (1862) 
    20 Cal. 96
     (Zottman). The County asserts that these
    decisions convey a general hostility toward quantum meruit
    claims against the government that was then maintained under
    the Act.
    We draw a more limited rule from these cases. Each of
    these decisions involved express contracts entered into by public
    entities that were found to be void and unenforceable because
    they were made in violation of a statute or municipal charter.
    (Miller, supra, 20 Cal.2d at p. 86 [contract between county and
    Keene Act provides adequate alternative mechanisms for
    resolving reimbursement disputes.
    27
    COUNTY OF SANTA CLARA v. SUPERIOR COURT
    Opinion of the Court by Guerrero, C. J.
    contractor held illegal because it did not comply with statute
    requiring public agencies to let competitive bidding before
    entering into certain contracts]; Los Angeles Dredging Co.,
    supra, 210 Cal. at p. 354 [contract entered into by city without
    letting of bids rendered void because it violated city charter];
    Zottman, supra, 20 Cal. at pp. 102–103 [same].) It was in this
    context, of considering contracts entered into by public entities
    in a manner not authorized by statute or charter, that we stated:
    “ ‘[C]ontracts wholly beyond the powers of a municipality are
    void. They cannot be ratified; no estoppel to deny their validity
    can be invoked against the municipality; and ordinarily no
    recovery in quasi contract can be had for work performed under
    them. It is also settled that the mode of contracting, as
    prescribed by the municipal charter, is the measure of the power
    to contract; and a contract made in disregard of the prescribed
    mode is unenforceable.’ [Citations.] And even though the
    person with whom the contract was made has supplied labor and
    materials in the performance of the contract and the public
    agency has received the benefits thereof, he has no right of
    action to recover in quantum meruit the reasonable value
    thereof.” (Miller, at p. 88, quoting Los Angeles Dredging Co., at
    p. 353.)
    Read together and as relevant here, Miller, Los Angeles
    Dredging Co., and Zottman stand for the narrow principle that
    if a contractor enters into an express contract with a public
    entity, and the contract is later found to be in violation of an
    applicable statute or charter and therefore deemed void, the
    contractor has no right to recover the reasonable value of
    services in quantum meruit. These decisions are readily
    distinguishable from the Hospitals’ quantum meruit claim
    against the County, which concerns no express contract and is
    28
    COUNTY OF SANTA CLARA v. SUPERIOR COURT
    Opinion of the Court by Guerrero, C. J.
    instead based on a statutorily mandated reimbursement
    provision. We are doubtful that the Legislature understood
    these decisions to mean that a quantum meruit claim for
    payment required by statute and otherwise resembling the claim
    pursued here is “a non-contractual action for money or damages,
    and thus a ‘tort,’ ” as the County asserts it must have.11
    Although other Court of Appeal decisions have broadly
    held that quantum meruit claims may not proceed against
    public entities, those decisions contain thin analyses and are
    distinguishable on their facts. It has been said, for example,
    that “[a]s a general rule, a public entity cannot be sued on an
    implied-in-law or quasi-contract theory, because such a theory
    is based on quantum meruit or restitution considerations which
    are outweighed by the need to protect and limit a public entity’s
    contractual obligations.”      (Lundeen Coatings Corp. v.
    Department of Water & Power (1991) 
    232 Cal.App.3d 816
    , 831,
    fn. 9; see also Janis v. California State Lottery Com. (1998)
    
    68 Cal.App.4th 824
    , 830; Los Angeles Equestrian Center, Inc. v.
    11
    Indeed, several other states allowed quasi-contractual
    claims to proceed against public entities under appropriate
    circumstances at the time the Legislature enacted the
    Government Claims Act. (See, e.g., Hailey v. King County
    (Wash. 1944) 
    149 P.2d 823
    , 825 [“the doctrine of implied contract
    has been applied with respect to municipal corporations under
    circumstances where ‘equity and good conscience’ have seemed
    to require it”]; Annot., Liability of Municipality or Other
    Governmental Body on Implied or Quasi Contract for Value of
    Property or Work (1945) 
    154 A.L.R. 356
    , 357 [“the rule is well
    settled in most jurisdictions that a municipality or other
    political subdivision may become obligated upon implied or
    quasi contract to pay the reasonable value of benefits accepted
    or appropriated by it as to which it has the general power to
    contract”].)
    29
    COUNTY OF SANTA CLARA v. SUPERIOR COURT
    Opinion of the Court by Guerrero, C. J.
    City of Los Angeles (1993) 
    17 Cal.App.4th 432
    , 448–449.) But
    these cases either directly or indirectly rely on Miller, supra,
    
    20 Cal.2d 83
     for this principle, and as has been explained, Miller
    does not stand for such a broad proposition. And even this
    principle is explicitly premised on “the need to protect and limit
    a public entity’s contractual obligations” (Lundeen, at p. 831,
    fn. 9), which is not a consideration for all quantum meruit
    claims — the instant claim against the County being just one
    example, since it is based on the County’s statutory duty, not its
    contractual obligation.
    In concluding that Government Code section 815 bars a
    quantum meruit action, the Court of Appeal below relied
    primarily on Sheppard v. North Orange County Regional
    Occupational Program (2010) 
    191 Cal.App.4th 289
    . (See Santa
    Clara, supra, 77 Cal.App.5th at p. 1028.) The plaintiff in
    Sheppard, a part-time public school instructor, sought
    reimbursement from a public agency for his unpaid time spent
    preparing for teaching. (Sheppard, at pp. 293–294.) Notably,
    an express contract existed between the plaintiff and the
    agency. (Id. at pp. 295, 314.) The plaintiff’s complaint alleged
    causes of action for violation of the minimum wage law, breach
    of contract, and quantum meruit. (Id. at p. 294.) The appellate
    court held that the trial court erred when it sustained the
    agency’s demurrer to the breach of contract claim (id. at p. 313),
    but that it properly sustained the demurrer to the plaintiff’s
    quantum meruit claim because “such a claim cannot be asserted
    against a public entity” (id. at p. 314). Sheppard cited
    Government Code section 815 and the Legislative Committee
    Comment accompanying that section, which states that this
    section “ ‘abolishes all common law or judicially declared forms
    of liability for public entities, except for such liability as may be
    30
    COUNTY OF SANTA CLARA v. SUPERIOR COURT
    Opinion of the Court by Guerrero, C. J.
    required by the state or federal constitution.’ ” (Sheppard, at
    p. 314.) The Sheppard court also determined that the plaintiff’s
    quantum meruit claim failed on the additional ground that such
    recovery is unavailable when the parties have an actual
    agreement covering compensation. (Ibid.)
    Without calling the result in Sheppard into question, to
    the extent it relied on the Government Claims Act, its analysis
    failed to undertake a careful review of the claim before it,
    comparable to our inquiries in City of Dinuba, supra, 
    41 Cal.4th 859
     and Kizer, 
    supra,
     
    53 Cal.3d 139
    , before determining
    whether such claim fell within or outside the purview of the
    Government Claims Act’s immunity provisions. To the extent it
    held that a quantum meruit claim against the public agency was
    unavailable more generally, Sheppard is plainly distinguishable
    because an express contract existed between the parties.
    To summarize, we are not persuaded that the Legislature
    intended to foreclose all quantum meruit claims against public
    entities when it drafted the Government Claims Act’s immunity
    and liability provisions, and certainly not the claim at issue in
    this case.
    In light of our holding that the Government Claims Act
    does not immunize the County from the Hospitals’ action for
    reimbursement as mandated by section 1371.4 of the Knox-
    Keene Act, we need not address the Hospitals’ alternative
    argument that the mandatory duty exception to governmental
    immunity under Government Code section 815.6 also applies.
