    _____________________________________________
    INTRODUCTION
    The Council for Education and Research on Toxics
    (CERT) brought these actions under Proposition 651 (Prop.
    65) against respondents, dozens of companies that roast,
    distribute, or sell coffee.2 CERT claimed that respondents
    1    The Safe Drinking Water and Toxic Enforcement Act of
    1986. (Health & Saf. Code, § 25249.5 et seq.)
    2    “Proposition 65 prohibits any person, in the course of doing
    business, from knowingly and intentionally exposing any
    (Fn. is continued on the next page.)
    4
    had failed to provide required Prop. 65 warnings for their
    coffee products based on the presence of acrylamide, which is
    included in the Prop. 65 list of known carcinogens and is
    naturally produced in coffee as a result of the roasting and
    brewing processes.
    While the litigation was pending, the Office of
    Environmental Health Hazard Assessment (the Agency),
    charged with implementing Prop. 65, adopted a new
    regulation providing that “[e]xposures to chemicals in coffee,
    listed on or before March 15, 2019 as known to the state to
    cause cancer, that are created by and inherent in the
    processes of roasting coffee beans or brewing coffee do not
    pose a significant risk of cancer.” (Cal. Code Regs., tit. 27,
    § 25704; the Coffee Regulation.) This regulation meant that
    coffee generally did not require Prop. 65 warnings.
    Respondents then moved for summary judgment, asserting
    the Coffee Regulation as a defense, while CERT moved for
    summary adjudication, challenging the regulation’s validity
    on various grounds. In opposing summary judgment, CERT
    also contended that regardless of the regulation, triable
    issues remained regarding the presence of acrylamide
    resulting from additives (plant roots, nuts, and seeds) in
    some coffee products, which the regulation did not address.
    It requested a continuance to conduct discovery regarding
    individual to a chemical known to the state to cause cancer or
    reproductive toxicity without giving a specified warning, . . .
    except as specified. (§ 25249.5 et seq.)” (DiPirro v. American
    Isuzu Motors, Inc. (2004) 
    119 Cal.App.4th 966
    , 969-970.)
    5
    additives in respondents’ products. The trial court denied
    CERT’s motions and granted summary judgment for
    respondents, concluding that the Coffee Regulation was
    valid and dispositive of CERT’s actions, and that claims
    regarding additives were outside the scope of the actions.
    After the court entered judgment for respondents,
    CERT moved to recover attorney fees from some of the
    respondents, on the basis that its litigation efforts catalyzed
    those respondents to post Prop. 65 warnings voluntarily
    during the pendency of its actions. The trial court denied
    CERT’s motion, concluding it was ineligible for fees because
    it had lost its case on the merits and conferred no significant
    benefit on the public.
    As relevant here, a few of the respondents (Starbucks
    Corporation, Starbucks Holding Company, Seattle Coffee
    Company, Peet’s Operating Company, and Dunkin’ Brands,
    Inc.; the Section 998 respondents) sought an award of costs
    under Code of Civil Procedure section 998 (section 998),
    based on compromise offers CERT had rejected during the
    litigation. CERT moved to tax costs, contending, inter alia,
    that the offers were invalid because they were conditioned
    on court approval (as required by Prop. 65), and because the
    releases they included were overbroad. The trial court
    denied the motion to tax costs and awarded the relevant
    respondents almost $700,000 in post-offer costs.
    In these consolidated appeals, CERT challenges the
    trial court’s grant of summary judgment for respondents, its
    denial of its motion for fees, and its award of section 998
    6
    costs. As to summary judgment, CERT contends the Coffee
    Regulation was arbitrary and capricious because: (1) the
    Agency failed to explain its departure from a prior position
    expressed in a 2005 report; (2) the Agency’s Final Statement
    of Reasons in support of the regulation failed to address
    CERT’s objection relating to the claimed departure; (3) the
    regulation is underinclusive and thus is not supported by its
    rationale; and (4) the regulation is scientifically
    unsupported.3 CERT also contends that triable issues
    remained as to acrylamide from coffee additives, and that
    the trial court should have granted a continuance for
    additional discovery on these issues. As discussed below, we
    conclude the regulation was validly adopted, and that claims
    regarding coffee additives are beyond the scope of CERT’s
    actions. Summary judgment was therefore appropriate.
    Challenging the denial of attorney fees, CERT
    reiterates its position that it was entitled to fees based on
    the voluntary warnings provided by the relevant
    respondents. We agree with the trial court that in light of
    the Coffee Regulation, these temporary warnings proved
    unnecessary and therefore conferred no significant benefit
    on the public, rendering CERT ineligible for fees.
    Finally, as to the award of costs to the section 998
    respondents, CERT contends their compromise offers were
    invalid because: (1) settlement offers in Prop. 65 cases can
    3    With our permission, the Agency filed an amicus brief in
    support of affirmance.
    7
    never be valid under section 998, as they require court
    approval; and (2) the relevant respondents’ offers included
    overly broad releases. We agree that the releases in the
    section 998 offers were overbroad and thus rendered the
    offers invalid. Accordingly, we reverse the trial court’s
    denial of CERT’s motion to tax costs.
    BACKGROUND4
    A. CERT’s Pre-Suit Notices and Actions
    In 2010, CERT sent two sets of notices of violations
    under Prop. 65 to numerous companies that roasted,
    distributed, or sold coffee in California.5 CERT’s notices
    alleged that the companies had failed to warn that their
    coffee products exposed Californians to high levels of
    acrylamide, a chemical included in Prop. 65’s list of known
    carcinogens. (Office of Environmental Health Hazard
    Assessment, The Proposition 65 List, at
     [as
    4   We deny CERT’s motions for judicial notice and
    augmentation of the record as either irrelevant or unnecessary.
    5      As discussed below, any person may bring an action under
    Prop. 65 “in the public interest” (Health & Saf. Code, § 25249.7,
    subd. (d)), provided they first give notice of the claimed violations
    to the alleged violator, the Attorney General, and others (id.,
    § 25249.7, subd. (d)(1)). A person who violates Prop. 65 is subject
    to civil penalties of up to $2,500 per day for each violation (id.,
    § 25249.7, subd. (b)(1)), and a person who is suing under Prop. 65
    in the public interest is entitled to 25 percent of the penalties
    collected (id., § 25249.12, subd. (d)).
    8
    of Oct. 24, 2022].) One set of notices alleged that
    “[e]xposures to acrylamide unavoidably occurred via
    ingestion whenever a consumer purchased and thereafter
    consumed the coffee produced, distributed, and/or sold by the
    above named entities.” The other set, targeting the relevant
    companies’ “ready-to-drink coffee,” similarly alleged that
    “[e]xposures to acrylamide unavoidably occurred via
    ingestion whenever a consumer purchased and thereafter
    consumed the above named entities’ ready-to-drink coffee.”
    CERT subsequently filed two actions under Prop. 65
    against the previously noticed companies, repeating the
    essential allegations in its pre-suit notices. The actions were
    consolidated, and the matter proceeded through various
    phases of a bifurcated trial.
    B. Trial Phases 1 and 2
    At phases 1 and 2 of the trial, the court rejected
    multiple affirmative defenses asserted by respondents. The
    court also granted CERT’s motion for summary adjudication,
    concluding it had established its prima facie case against
    most of the respondents, who had stipulated to facts that
    supported CERT’s prima facie case. The matter was
    scheduled to proceed to a remedies phase in October 2018.
    C. The International Agency for Research on Cancer
    Monograph
    On June 13, 2018, the International Agency for
    Research on Cancer (IARC) -- an authoritative body for the
    9
    identification of chemicals causing cancer under Prop. 65
    (Cal. Code Regs., tit. 27, § 25306, subd. (m)(1)) -- released a
    501-page monograph on the cancer risks of coffee
    consumption (the Monograph). Based on “more than 1000
    observational and experimental studies,” the Monograph
    found there was “inadequate evidence in humans and
    experimental animals for the carcinogenicity of coffee
    drinking.”6 The document acknowledged that a working
    group in 1991 had found that coffee caused cancer of the
    urinary bladder, but explained that the new working group
    focused on higher-quality epidemiological studies, which
    showed no consistent association, and suggested that the
    prior association observed in some studies was “probably due
    to inadequate control for the confounding effects of tobacco
    smoking.”
    The Monograph continued: “In considering the data
    now available for more than 20 other cancer sites in humans,
    the Working Group found evidence suggesting lack of
    carcinogenicity for cancers of the female breast, uterine
    endometrium, prostate, pancreas, and liver, and inadequate
    evidence in humans for cancers at all other sites. The
    Working Group’s review of other relevant data found strong
    6     The Monograph elsewhere defined the phrase “Inadequate
    evidence of carcinogenicity” as denoting that “[t]he available
    studies are of insufficient quality, consistency or statistical power
    to permit a conclusion regarding the presence or absence of a
    causal association between exposure and cancer, or no data on
    cancer in humans are available.”
    10
    evidence in humans that coffee has antioxidant effects. As a
    result of this re-evaluation, the Working Group concluded
    that drinking coffee is not classifiable as to its
    carcinogenicity to humans . . . .” The document additionally
    noted that “[i]nverse associations with drinking coffee have
    been observed with cancers of the liver and uterine
    endometrium,” suggesting that coffee reduced the risks of
    those cancers.
    D. Adoption of the Coffee Regulation
    1. Proposed Regulation and Initial Statement of
    Reasons
    On June 15, 2018, shortly after the IARC released its
    Monograph, the Agency published a notice of its intent to
    adopt a new regulation, to provide that “[e]xposures to listed
    chemicals in coffee created by and inherent in the processes
    of roasting coffee beans or brewing coffee do not pose a
    significant risk of cancer.”7 (Underlining omitted.) That
    same month, the Agency issued an Initial Statement of
    Reasons (ISR) in support of the proposed regulation, and
    stated that if it adopted the regulation, no cancer warnings
    would be required for exposure to the relevant chemicals in
    coffee.
    7      In the trial court, respondents unsuccessfully sought a stay
    of the remedies phase of trial pending the Agency’s adoption of
    the proposed regulation. Respondents then sought and obtained
    a stay from this court.
    11
    In the ISR, the Agency noted, “Coffee is . . . unusual
    because it has been the subject of very high scientific
    interest for many years -- IARC reviewed more than 1000
    observational and experimental studies investigating the
    potential carcinogenicity of coffee in humans and animals.”
    It explained, “Coffee is unique in that it shows reductions in
    certain human cancers, has not been shown to increase any
    cancers, and is particularly rich in cancer chemopreventive
    compounds.” The ISR listed antioxidants, anti-inflammatory
    chemicals, and soluble and insoluble fiber as “constituents
    that exhibit cancer chemopreventive properties,” and cited
    numerous articles published in scientific journals to support
    its position regarding these categories of coffee constituents.
    2. Public Comments and the 2005 Report
    During the public comment period, the Agency received
    numerous submissions and held a public hearing, at which it
    received oral comments. Some commentors contended that
    the Agency should assess the cancer risk from acrylamide in
    coffee in isolation, without consideration of coffee as a
    mixture. CERT objected, inter alia, that the Agency had
    failed to consider and address its own 2005 report regarding
    acrylamide intake in various foods and beverages.
    The 2005 report was prepared in support of a proposed
    regulation that was subsequently withdrawn. According to
    the report, its purpose was to “assist the public and the
    regulated community in estimating average daily intake of
    acrylamide from specific foods, and to inform the
    12
    development and content of regulations proposed by OEHHA
    . . . .” Based on various data, the report estimated coffee
    drinkers’ daily intake of acrylamide from coffee, and
    concluded that coffee was a substantial source of exposure to
    acrylamide, and that drinkers likely exceeded the previously
    set “No Significant Risk Level” (NSRL) for acrylamide. The
    NSRL represents a safe harbor that protects businesses from
    liability relating to exposure to a listed chemical under Prop.
    65. If the level of exposure from a product is below the
    NSRL, the safe harbor is triggered, and no warning is
    required. (Cal. Code Regs., tit. 27, § 25705.)
    3. The Agency’s Modification of the Proposed
    Regulation
    On March 15, 2019, the Agency announced it was
    modifying its proposed regulation to limit the exempted
    exposures to chemicals listed as of that date. The modified
    proposed regulation therefore provided: “Exposures to
    chemicals in coffee, listed on or before March 15, 2019 as
    known to the state to cause cancer, that are created by and
    inherent in the processes of roasting coffee beans or brewing
    coffee do not pose a significant risk of cancer.”
    4. The Agency’s Final Statement of Reasons and
    Adoption of the Regulation
    Following the comment period, the Agency issued a
    lengthy Final Statement of Reasons (FSR), which responded
    to public comments and concluded that the available
    13
    scientific information supported the regulation. The Agency
    explained that because extensive research suggested that
    coffee, as a mixture, posed no significant risk of cancer, the
    individually listed chemicals formed through the roasting
    and brewing process also posed no significant risk of cancer
    when combined and consumed in the mixture. The FSR
    listed “[the Agency]’s key overall considerations in adopting
    this regulation”:
    “‘[1] There is inadequate evidence for the
    carcinogenicity of drinking coffee, based on a very
    large number of human studies.
    “‘[2] There are inverse associations––decreasing
    risk with increasing coffee consumption - for
    human cancers of the liver and uterine
    endometrium.
    “‘[3] There is inadequate evidence of increased
    carcinogenicity in animals administered coffee in
    controlled experiments.
    “‘[4] There are inverse associations in a number of
    animal experiments and the overall evidence
    from animal studies is that of reduced incidence
    or reduced multiplicity of cancers with coffee
    intake.
    “‘[5] There is a rich mix of cancer-preventative
    agents in brewed coffee.’”
    (Fns. omitted.)
    14
    Relying in part on the IARC Monograph, the FSR
    repeatedly noted the IARC’s conclusion that coffee was “‘not
    classifiable as to its carcinogenicity to humans.’” While the
    IARC Monograph featured prominently in the FSR, the
    Agency did not merely adopt its conclusions, and explained
    that the Agency’s determination regarding the risk of cancer
    from coffee was “strongly supported by the extensive
    research evaluated and summarized by IARC and by [the
    Agency]’s evaluation of the IARC Monograph and studies
    published subsequent to the IARC review . . . .”
    In its FSR, the Agency did not expressly address
    CERT’s objection that it had failed to consider the 2005
    report and its conclusion that coffee drinkers exceeded the
    NSRL for acrylamide. However, in addressing the comments
    urging the Agency to examine the risk from acrylamide in
    coffee in isolation, it explained that given the large volume of
    research regarding the cancer risk from coffee as a mixture,
    it was appropriate to assess the evidence relating to the
    mixture as a whole, and explained that “reliance on a single
    carcinogenic constituent to infer significant risk can result in
    a substantial mischaracterization of the risk profile.” In
    June 2019, the Office of Administrative Law approved the
    Coffee Regulation (as modified in March 2019).
    15
    E. Respondents’ Assertion of the Regulation as a
    Defense, and the Motions for Summary Adjudication
    and Summary Judgment
    Following the Agency’s adoption of the Coffee
    Regulation, respondents moved to amend their answers to
    add the regulation as an affirmative defense, and the trial
    court granted them leave to do so. CERT then filed several
    motions for summary adjudication, attacking the validity of
    the Coffee Regulation on various grounds. In turn,
    respondents moved for summary judgment based on the
    regulation.8
    Following hearings, the trial court denied CERT’s
    motions for summary adjudication and granted respondents’
    motion for summary judgment, rejecting CERT’s challenges
    to the Coffee Regulation’s validity. Addressing CERT’s
    contention that issues remained regarding acrylamide
    resulting from additives in some of respondents’ coffee
    products, the court concluded such claims were outside the
    scope of CERT’s actions, based, inter alia, on the allegations
    in its pre-suit notices and complaints.
    8     While these motions were pending, CERT served
    respondents with document requests, seeking information
    relating to additives included in some coffee products. It then
    moved for a continuance to conduct additional discovery
    regarding this issue. The trial court did not expressly address
    CERT’s motion, but as discussed below, in granting summary
    judgment for respondents, it ruled that claims relating to coffee
    additives were outside the scope of CERT’s actions.
    16
    F. CERT’s Motion for Attorney Fees
    After the entry of judgment, CERT moved to recover
    attorney fees from 18 of the respondents under Code of Civil
    Procedure section 1021.5. Acknowledging it had lost its case
    on the merits in the trial court, CERT claimed it was
    nevertheless a successful party entitled to fees under the
    “‘catalyst theory,’” asserting that its litigation efforts had
    caused the relevant respondents to provide Prop. 65
    warnings voluntarily during the litigation period.9
    The trial court denied CERT’s motion, concluding it
    was not a successful party eligible for fees even under the
    catalyst theory, as it had lost its case on the merits. The
    court determined, alternatively, that CERT was not eligible
    for fees because it had not conferred a significant benefit on
    the public, as any warnings given during the pendency of its
    actions “were ultimately proven unnecessary for public
    health” under the Coffee Regulation.
    G. The Award of Costs under Section 998
    As discussed more fully below, during the litigation,
    the section 998 respondents served statutory offers of
    compromise on CERT, which rejected the offers. After entry
    9    “Under the catalyst theory, attorney fees may be awarded
    even when litigation does not result in a judicial resolution if the
    defendant changes its behavior substantially because of, and in
    the manner sought by, the litigation.” (Graham v.
    DaimlerChrysler Corp. (2004) 
    34 Cal.4th 553
    , 560.)
    17
    of judgment, these respondents filed memoranda of costs
    seeking to recover their post-offer costs. CERT moved to tax
    costs, challenging the validity of the section 998 offers, but
    the trial court denied its motion and awarded the requested
    costs. This appeal followed.
    DISCUSSION
    CERT challenges the trial court’s grant of summary
    judgment, its denial of attorney fees to CERT, and its award
    of costs to the section 998 respondents. We conclude the
    trial court properly granted summary judgment and properly
    denied CERT’s motion for fees. However, we agree with
    CERT that the court erred in awarding the relevant
    respondents costs under section 998.
    A. Summary Judgment
    CERT claims the trial court erred in granting
    summary judgment for respondents and denying its motions
    for summary adjudication, because (1) the Coffee Regulation,
    on which the court’s order rested, was invalid, and (2) even
    assuming the regulation was valid, triable issues remained
    regarding acrylamide from coffee additives. As discussed
    below, we find neither contention persuasive.
    18
    1. Standards of Review
    a. Summary Judgment
    We review the trial court’s rulings on CERT’s motions
    for summary adjudication and respondents’ motion for
    summary judgment de novo. (Gresher v. Anderson (2005)
    
    127 Cal.App.4th 88
    , 96.) A motion for summary judgment or
    summary adjudication is properly granted if the moving
    papers establish that there is no triable issue of material
    fact, and the moving party is entitled to judgment as a
    matter of law. (Code Civ. Proc., § 437c, subd. (c); Aguilar v.
    Atlantic Richfield Co. (2001) 
    25 Cal.4th 826
    , 843.)
    b. Administrative Regulations
    The Agency adopted the coffee regulation under its
    authority to “adopt and modify regulations . . . as necessary
    to conform with and implement [Prop. 65].” (Health & Saf.
    Code, § 25249.12, subd. (a).) A regulation adopted pursuant
    to a delegation of lawmaking power has “the dignity of
    statutes.” (Yamaha Corp. of America v. State Bd. of
    Equalization (1998) 
    19 Cal.4th 1
    , 10.) “When a court
    assesses the validity of such rules, the scope of its review is
    narrow. If satisfied that the rule in question lay within the
    lawmaking authority delegated by the Legislature, and that
    19
    it is reasonably necessary to implement the purpose of the
    statute, judicial review is at an end.”10 (Id. at 10-11.)
    Our review of whether a regulation is reasonably
    necessary is limited to “whether the rule is arbitrary,
    capricious, or without rational basis [citation] and whether
    substantial evidence supports the agency’s determination
    that the rule is reasonably necessary.” (Western States
    Petroleum Assn. v. Board of Equalization (2013) 
    57 Cal.4th 401
    , 415.) Under this standard, the challenged regulation is
    presumptively valid, and the burden is on the party
    challenging it to show that it is infirm. (Tomlinson v.
    Qualcomm (2002) 
    97 Cal.App.4th 934
    , 940-941.) In the
    absence of an arbitrary and capricious decision, we will defer
    to the agency’s expertise (Ford Dealers Assn. v. Department
    of Motor Vehicles (1982) 
    32 Cal.3d 347
    , 355), and “will not
    . . . venture into an independent determination of the
    wisdom of the challenged regulation” or “substitute our
    judgment for that of the agency with respect to such things
    as the existence and weight to be accorded the facts and
    policy considerations . . . .” (Western States Petroleum Assn.
    v. State Dept. of Health Services (2002) 
    99 Cal.App.4th 999
    ,
    1007.)
    10    While CERT suggests these principles are inapplicable to
    an indirect challenge to the validity of a regulation in the context
    of summary judgment, it cites no relevant authority for this
    proposition, and we are aware of none.
    20
    2. Analysis
    CERT challenges the regulation on multiple grounds,
    asserting: (1) the Agency failed to explain its departure from
    the prior position it expressed in the 2005 report; (2) the
    Agency’s FSR failed to address CERT’s objection based on
    the claimed departure; (3) the regulation is underinclusive
    and thus is not supported by its rationale; and (4) the
    regulation is scientifically unsupported. We address these
    contentions in turn.
    a. There Was No Conflict Between the
    Regulation and the 2005 Report
    Citing federal caselaw applying the federal
    Administrative Procedures Act, CERT contends that an
    agency adopting a regulation contrary to its prior
    conclusions must acknowledge and explain the departure.
    Assuming, without deciding, that such a requirement exists
    under California law, we conclude it would have no
    application here, because the Coffee Regulation was not
    contrary to the Agency’s 2005 report.
    As noted, the 2005 report was a technical document
    dealing with the intake levels of acrylamide in different
    foods and beverages. Its purpose was to “assist the public
    and the regulated community in estimating average daily
    intake of acrylamide from specific foods, and to inform the
    development and content of regulations proposed by OEHHA
    . . . .” The report concluded that coffee drinkers likely
    21
    exceeded both the NSRL for acrylamide, and that coffee was
    a substantial source of exposure to acrylamide.
    Contrary to CERT’s suggestion, the conclusion that
    coffee drinkers exceeded the NSRL for acrylamide did not
    encompass a determination that coffee drinking caused
    cancer. As explained above, the NSRL provides a safe
    harbor. That an exposure level exceeds the NSRL does not
    imply it presents a significant risk of cancer. “In [the
    Agency]’s words, its establishment of a[n] NSRL ‘expressly is
    not a determination that any level above the NSRL poses a
    significant risk.’” (Baxter Healthcare Corp. v. Denton (2004)
    
    120 Cal.App.4th 333
    , 358.) These safe harbor levels do not
    preclude the use of alternative levels that can be
    demonstrated to be safe. (See Cal. Code Regs., tit. 27,
    § 25701, subd. (a) [“Nothing in this article shall preclude a
    person from using evidence, standards, risk assessment
    methodologies, principles, assumptions or levels not
    described in this article to establish that a level of exposure
    to a listed chemical poses no significant risk”].)
    The 2005 report included no independent risk
    assessment and did not address whether coffee caused
    cancer or whether any cancer risk inherent in coffee
    drinking should be assessed based on the mixture or its
    constituents. Thus, the Coffee Regulation’s determination
    that exposure to acrylamide inherent in coffee did not pose a
    significant risk of cancer contradicted nothing in the 2005
    22
    report, and there was therefore no change of position calling
    for any explanation.11
    b. The Agency Substantially Complied with
    Its Duty to Address CERT’s Objections
    i. Governing Principles
    Under the California Administrative Procedures Act
    (APA), before adopting a proposed regulation, an agency
    must provide an FSR that includes, among other things, a
    summary of “each objection or recommendation made
    regarding the [proposed regulatory action], together with an
    explanation of how the proposed action has been changed to
    accommodate each objection or recommendation, or the
    reasons for making no change.” (Gov. Code, § 11346.9, subd.
    (a)(3).) An agency’s “substantial failure” to comply with the
    APA’s requirements may result in the regulation’s
    invalidation. (Gov. Code, § 11350, subd. (a).)
    Construing the phrase “substantial failure” in the APA,
    the court in Sims v. Department of Corrections &
    Rehabilitation (2013) 
    216 Cal.App.4th 1059
     (Sims) relied on
    the concept of “[s]ubstantial compliance,” which it described
    as “the counterpart, or obverse, of the substantial failure to
    comply, which negatively expresses the same idea.” (Id. at
    11    As discussed below, the Agency sufficiently explained its
    decision to forgo a quantitative assessment of coffee’s
    constituents in favor of a qualitative assessment of the mixture
    as a whole.
    23
    1073.) “‘[S]ubstantial compliance . . . means actual
    compliance in respect to the substance essential to every
    reasonable objective of the statute. But when there is such
    actual compliance as to all matters of substance[,] then mere
    technical imperfections of form . . . should not be given the
    stature of noncompliance . . . .’” (Id. at 1073, quoting Stasher
    v. Harger-Haldeman (1962) 
    58 Cal.2d 23
    , 29.)
    ii. Application
    Although the Agency did not expressly address CERT’s
    objection that it had failed to consider the 2005 report’s
    conclusion that coffee drinkers exceeded the NSRL for
    acrylamide, it sufficiently addressed the substance of the
    objection by explaining its rejection of a quantitative NSRL
    like the one employed in the report. The Agency thus did not
    substantially fail to comply with the APA’s requirements.
    As noted, the Agency addressed comments claiming
    that cancer risk from acrylamide in coffee should be assessed
    in isolation, without consideration of coffee as a mixture. It
    explained that given the large volume of research concerning
    the cancer risk from coffee as a mixture, it was appropriate
    to assess the evidence relating to the mixture as a whole,
    and stated that “reliance on a single carcinogenic constituent
    to infer significant risk can result in a substantial
    mischaracterization of the risk profile.” That the Agency
    addressed the substance of CERT’s concern without
    expressly referencing the 2005 report constituted, at most, a
    “‘mere technical imperfection[] of form,’” which will not
    24
    invalidate a regulation.12 (Sims, supra, 216 Cal.App.4th at
    1073.)
    c. The Coffee Regulation is Consistent with
    the Agency’s Rationale
    Contrary to CERT’s contention, the Coffee Regulation
    is consistent with the rationale offered by the Agency. In
    adopting the regulation, the Agency explained that because
    extensive research suggested that coffee, as a mixture, posed
    no significant risk of cancer, the individual listed chemicals
    formed through the roasting and brewing process also posed
    no significant risk of cancer when combined and consumed
    in the mixture. We see nothing inconsistent or illogical in
    this rationale.
    CERT notes that the regulation applies only to
    chemicals listed on or before March 15, 2019, and argues it is
    12     Any technical noncompliance by the Agency in failing to
    expressly reference the 2005 report is a far cry from the
    substantial failures in the cases CERT cites in support of its
    position. (See Sims, supra, 216 Cal.App.4th at 1074 [California
    Department of Corrections and Rehabilitation violated APA by:
    failing to set forth alternatives to its proposed lethal injection
    protocol, failing to explain rejection of various alternatives,
    falsely representing how it selected proposed method, failing to
    include required documents in rulemaking file, and failing to
    make file publicly available in timely manner]; Mountain Lion
    Foundation v. Fish & Game Com. (1997) 
    16 Cal.4th 105
    , 133
    [noting Office of Administrative Law’s disapproval of regulatory
    action where agency’s final statement of reasons failed to include
    any summary and response to public comments].)
    25
    arbitrary and capricious because “[i]f [the Agency’s]
    rationale for the regulation were true and valid, there would
    be no basis for excluding unlisted carcinogens from the scope
    of the regulation” because “unlisted carcinogens in coffee
    could no more present a significant risk of cancer . . . than
    could listed carcinogens.” But “regulations are ‘not invalid
    merely because they are to some extent underinclusive or
    overinclusive . . . .’” (State Farm General Insurance
    Company v. Lara (2021) 
    71 Cal.App.5th 148
    , 183.) The
    Agency was entitled to address currently listed chemicals
    first, saving for another day any chemicals inherent in the
    roasting and brewing of coffee that might be listed in the
    future. (See ibid.; Western States Petroleum Assn. v. Board
    of Equalization, 
    supra,
     57 Cal.4th at 421 [regulation that
    singled out petroleum refineries, even though its rationale
    applied to other types of industrial facilities as well, was not
    arbitrary and capricious]; cf. U.S. Cellular Corp. v. F.C.C.
    (D.C. Cir. 2001) 
    254 F.3d 78
    , 86 [“agencies need not address
    all problems ‘in one fell swoop,’” and “‘[r]eform may take
    place one step at a time, addressing itself to the phase of the
    problem which seems most acute to the [regulatory] mind’”].)
    The regulation is therefore consistent with its rationale.
    d. CERT Has Not Shown That the Coffee
    Regulation Lacks Scientific Foundation
    CERT claims the regulation lacks scientific foundation
    for several reasons. It contends: (1) Lockheed Litigation
    Cases (2004) 
    115 Cal.App.4th 558
     (Lockheed) held that IARC
    26
    monographs are insufficiently reliable; (2) the IARC is not
    an authoritative body for cancer risk assessment; (3) the
    Agency misrepresented the IARC’s conclusions in various
    ways; and (4) the Agency relied in part on an unsupported
    finding that antioxidants in coffee had an anti-carcinogenic
    effect. We find none of these contentions convincing.
    First, CERT cites Lockheed for the proposition that an
    IARC monograph regarding a chemical mixture is
    scientifically unreliable for purposes of determining human
    cancer risk from a chemical within the mixture. Lockheed is
    inapposite. There, the court held that an expert could not
    reasonably opine that exposure to five particular chemicals
    caused cancer based on an IARC study that found that
    “painters who potentially were exposed to a long list of more
    than 130 substances and thousands of chemical compounds
    contracted cancer” at a higher rate. (Lockheed, supra, 
    115 Cal.App.4th 558
    , 564-565.) The court explained that the
    expert’s opinion was “based on conjecture and speculation as
    to which of the many substances to which the study subjects
    were exposed contributed to the greater incidence of cancer.”
    (Id. at 565.) This analysis has no application here, where
    the IARC Monograph evaluated the very mixture addressed
    by the Coffee Regulation, and tended to negate a substantial
    risk of cancer from it. While the IARC Monograph provides
    no basis for determining the cancer risk from an individual
    constituent of coffee, like acrylamide, in isolation, the Coffee
    Regulation rests on the Agency’s conclusions regarding the
    27
    risk of cancer from coffee as a mixture -- a conclusion the
    Monograph tends to support.
    Second, CERT complains that “while IARC is an
    authoritative body for the identification of chemicals as to
    their carcinogenicity to humans (i.e., cancer hazard
    assessment), it is not recognized as an authoritative body for
    quantifying risks of cancer from carcinogens (i.e., cancer risk
    assessment).” CERT fails to explain the significance of this
    distinction for purposes of the Agency’s reliance on the IARC
    Monograph. As the Monograph itself explains,
    “[m]onographs represent the first step in carcinogenic risk
    assessment,” and they “identify cancer hazards even when
    risks are very low at current exposure levels.” The Agency
    therefore reasonably relied on the IARC’s findings regarding
    coffee’s carcinogenicity and its Monograph’s conclusion that
    coffee was “not classifiable as to its carcinogenicity.” (Italics
    omitted.)
    Third, CERT claims that in various ways, the Agency’s
    FSR gave a “false impression” that the IARC had concluded
    coffee does not cause cancer, when in fact the Monograph
    concluded only that there was inadequate evidence for
    coffee’s carcinogenicity. We disagree. The Agency’s FSR
    quoted multiple times the IARC’s overall conclusion that
    coffee was “‘not classifiable as to its carcinogenicity to
    humans.’” CERT points to the FSR’s statement of the
    Agency’s key considerations in adopting the regulation, and
    complains that it presents the IARC’s conclusions in a
    misleading manner because of its wording, its use of the
    28
    phrase “‘inadequate evidence’” without providing the IARC’s
    definition for the phrase, and its omission of relevant context
    from the IARC Monograph. However, the FSR’s statement
    of key considerations represented the Agency’s conclusions,
    rather than those of the IARC. Indeed, the Agency
    explained that its determination regarding the risk of cancer
    from coffee relied on its own evaluation of the Monograph,
    the underlying research summarized by the Monograph, and
    “studies published subsequent to the IARC review . . . .”
    Finally, CERT challenges the FSR’s assertion that
    “[t]here is a rich mix of cancer-preventative agents in brewed
    coffee.” CERT speculates that this statement “apparently
    refers to antioxidants in coffee” and proceeds to contest the
    notion that antioxidants in coffee prevent cancer. Initially,
    there is no reason to think that the FSR’s reference to
    cancer-preventative agents was limited to antioxidants. In
    its ISR, the Agency listed anti-inflammatory chemicals as
    well as soluble and insoluble fiber, alongside antioxidants, as
    “constituents that exhibit cancer chemopreventive properties
    . . . .” The ISR cited numerous articles published in scientific
    journals to support its position that these categories of coffee
    constituents possessed anticarcinogenic properties. The
    Agency’s FSR referenced the ISR’s discussion of cancer-
    preventative agents and noted its citation to multiple
    scientific authorities in support of its conclusions.13
    13     CERT’s contention that the Agency relied on a single article
    is therefore incorrect.
    29
    Moreover, we decline CERT’s invitation to wade into a
    scientific debate about the effects of antioxidants in coffee or
    the quality of the studies on which the Agency relied in
    adopting the Coffee Regulation. Our task is to assess only
    whether the Agency’s adoption of the regulation was
    arbitrary or capricious. We may not “substitute our
    judgment for that of the agency” regarding “the existence
    and weight to be accorded the facts and policy considerations
    that support the regulation.” (Western States Petroleum v.
    State Dept. of Health Services, supra, 99 Cal.App.4th at
    1007.) In short, the regulation does not lack scientific
    foundation.
    e. Claims Regarding Acrylamide from
    Additives Are Beyond the Scope of CERT’s
    Actions
    CERT’s claims regarding acrylamide formed by the
    roasting of plant roots, nuts, and seeds added to coffee --
    which are not addressed by the Coffee Regulation --
    exceeded the scope of CERT’s actions, as delineated by its
    pre-suit notices. These claims therefore did not preclude
    summary judgment.
    Before bringing a Prop. 65 action in the public
    interest, a private plaintiff must provide a pre-suit notice
    containing sufficient information about the claim to (1) the
    Attorney General and other public prosecutors, to allow
    them to adequately investigate the claim’s basis, and (2) the
    alleged violator, to allow it an opportunity to cure the
    30
    violation. (See Health & Saf. Code, § 25249.7, subd. (d);
    Consumer Advocacy Group, Inc. v. Kintetsu Enterprises of
    America (2007) 
    150 Cal.App.4th 953
    , 960-961 (Consumer
    Advocacy Group).) This pre-suit notice must describe,
    among other things, “the specific type of consumer product
    . . . with sufficient specificity to inform the recipients of the
    nature of the items allegedly sold in violation of the law and
    to distinguish those products . . . from others sold . . . .”
    (Cal. Code Regs., tit. 27, § 25903, subd. (b)(2)(D).) Failure to
    comply with pre-suit notice requirements is grounds for
    dismissal, and deficiencies cannot be cured after the
    complaint is filed. (See Physicians Committee for
    Responsible Medicine v. KFC Corp. (2014) 
    224 Cal.App.4th 166
    , 181 (Physicians Com.).)
    It is undisputed that CERT’s pre-suit notices failed to
    distinguish regular coffee from a subset of coffee with
    additives from plant roots, nuts, or seeds, and made no
    mention of acrylamide from such additives as the basis of
    any violation. Indeed, CERT alleged that “[e]xposures to
    acrylamide unavoidably occurred via ingestion whenever a
    consumer purchased and thereafter consumed” the alleged
    violators’ “coffee” or “ready-to-drink coffee.” (Italics added.)
    This description provided no notice to respondents or public
    prosecutors that CERT’s claim targeted a subset of products
    containing coffee additives -- to which consumers were not
    exposed “whenever” they purchased respondents’ coffee --
    and thus that they should investigate the existence and
    31
    carcinogenicity of acrylamide produced from the roasting of
    such additives.
    CERT argues: “whether or not acrylamide-containing
    additives were mentioned in CERT’s pre-suit notices of
    violations, . . . acrylamide-containing additives became
    relevant to this case when [respondents] were granted leave
    to amend their answers to assert the Coffee Regulation,
    because that regulation does not exempt from liability
    companies that expose Californians to acrylamide-containing
    additives.” According to CERT, “to obtain summary
    judgment on their new defense, [respondents] were obliged
    to prove that defense applied to their products,” and thus,
    respondents “had to offer evidence that their coffee products
    did not contain any acrylamide-containing flavorings or
    other additives.”
    CERT’s argument ignores its pre-suit notice
    obligations. As noted, to allow alleged violators and public
    prosecutors to investigate claims, pre-suit notices must
    identify the specific type of consumer product, with sufficient
    specificity to distinguish it from others. (See Cal. Code
    Regs., tit. 27, § 25903, subd. (b)(2)(D); Consumer Advocacy
    Group, supra, 150 Cal.App.4th at 960-961.) That
    respondents’ defense precluded liability based on the broad
    category CERT identified in its notices does not excuse
    CERT from complying with this requirement. Under
    CERT’s approach, private plaintiffs would be able to cast a
    wide net, identifying vast categories of products in hopes of
    catching something that would support a violation, and
    32
    adjusting their claims according to developments in the
    litigation. This approach is contrary to Prop. 65’s intent to
    allow pre-suit investigation of alleged violations.
    Accordingly, we conclude that CERT’s broad and
    undifferentiated identification of “coffee” in its pre-suit
    notices prevents it from now pointing to a subset of coffee
    with additives from plant roots, nuts, and seeds as the basis
    for respondents’ liability.14 (See Consumer Advocacy Group,
    14     Given our conclusion, we need not address CERT’s
    additional contention that the trial court erred by failing to grant
    it a continuance to conduct additional discovery regarding coffee
    additives. In its reply brief, CERT argues for the first time that
    epidemiological studies of acrylamide in food are scientifically
    unreliable, citing an expert declaration filed by the Attorney
    General in a different case in January 2020 (after the Agency
    issued the Coffee Regulation but before the filing of CERT’s
    opening brief). Similarly, for the first time in its answer to the
    Agency’s amicus brief, CERT contends that the Agency adopted
    the Coffee Regulation due to political pressure, and that its
    rationale was simply a post hoc rationalization that cannot
    support the regulation. CERT has forfeited these contentions by
    failing to raise them in its opening brief. (See Tukes v. Richard
    (2022) 
    81 Cal.App.5th 1
    , fn. 5 [“A contention not appropriately
    raised in the opening brief under a separate argument heading
    may be deemed forfeited.”)
    Because we affirm the grant of summary judgment based
    on the Agency’s regulation and the conclusion that claims
    involving additives were outside the scope of CERT’s actions, we
    need not address respondents’ alternative argument that
    compelling them to provide Prop. 65 warnings would have
    violated the First Amendment.
    33
    supra, at 960-961; Physicians Com., supra, 224 Cal.App.4th
    at 181.)
    B. Attorney Fees
    CERT contends the trial court abused its discretion in
    denying its motion for attorney fees. It argues, among other
    things, that it conferred a significant benefit on the public,
    contrary to the trial court’s determination, because the
    voluntary, temporary Prop. 65 warnings posted by some
    respondents provided an “informational benefit.” As
    explained below, in light of the Agency’s determination that
    coffee poses no significant risk of cancer, we conclude CERT
    has shown no benefit from these temporary warnings.15
    1. Applicable Law
    a. Eligibility for Fees under Code of Civil
    Procedure Section 1021.5
    “[Code of Civil Procedure] [s]ection 1021.5 codifies the
    ‘private attorney general’ doctrine of attorneys fees
    15     We also question whether CERT could be deemed a
    successful party under the catalyst theory after litigating and
    losing its case on the merits. (See Skaff v. Rio Nido Roadhouse
    (2020) 
    55 Cal.App.5th 522
    , 540 [“we are not convinced that the
    catalyst theory should even apply here,” as “[t]he catalyst theory
    is generally not invoked in cases where the merits have been fully
    litigated to a final judgment”].) However, because we conclude
    that CERT conferred no significant benefit on the public, we need
    not decide the issue.
    34
    articulated in Serrano v. Priest (1977) 
    20 Cal.3d 25
     . . . and
    other judicial decisions.” (Flannery v. California Highway
    Patrol (1998) 
    61 Cal.App.4th 629
    , 634.) “The statute gives
    the trial court discretion to award fees to a successful party
    if (1) its action has resulted in the enforcement of an
    important public right, (2) the general public or a large class
    of persons has received a significant benefit, (3) the burden
    of private enforcement is disproportionate to the litigant’s
    personal interest, and (4) it is unfair to make a successful
    plaintiff pay the fees out of any recovery.” (Concerned
    Citizens of La Habra v. City of La Habra (2005) 
    131 Cal.App.4th 329
    , 334 (Concerned Citizens).)
    “The award of fees under section 1021.5 is an equitable
    function, and the trial court must realistically and
    pragmatically evaluate the impact of the litigation to
    determine if the statutory requirements have been met.
    [Citation.] This determination is ‘best decided by the trial
    court, and the trial court’s judgment on this issue must not
    be disturbed on appeal “unless the appellate court is
    convinced that it is clearly wrong and constitutes an abuse of
    discretion.” [Citations.]’” (Concerned Citizens, supra, 131
    Cal.App.4th at 334.)
    2. Analysis
    CERT has shown no benefit to the public from the
    temporary warnings provided, let alone an abuse of
    discretion in the trial court’s conclusion that no benefit had
    been conferred. CERT contends it conferred an
    35
    informational benefit in accord with Prop. 65’s purposes by
    advising consumers that the coffee contained a carcinogen
    and allowing them to make informed decisions regarding
    their coffee consumption. However, the Coffee Regulation,
    promulgated by the agency responsible for implementing
    Prop. 65, establishes that those warnings were unnecessary
    and misleading regarding the risk of cancer from coffee. The
    warnings therefore provided no informational benefit to
    consumers. (Cf. Dowhal v. SmithKline Beecham Consumer
    Healthcare (2004) 
    32 Cal.4th 910
    , 934 (Dowhal) [“a truthful
    warning of an uncertain or remote danger may mislead the
    consumer into misjudging the dangers stemming from use of
    the product, and consequently making a medically unwise
    decision”]; Nicolle-Wagner v. Deukmejian (1991) 
    230 Cal.App.3d 652
    , 661 (Nicolle-Wagner) [avoiding warnings
    regarding substances that pose insignificant risk of cancer
    “will further the statutory purpose [of Prop. 65] in
    safeguarding the effectiveness of warnings which are
    given”].)
    CERT argues that the warnings were required at the
    time they were posted, before the Coffee Regulation was
    issued, and suggests that its suit conferred a benefit by
    enforcing the law at the time. But even assuming that Prop.
    65 warnings for coffee were required before the Agency
    adopted the Coffee Regulation -- a matter we do not decide --
    enforcement of the law does not necessarily confer a
    significant benefit on the public. “Of course, the public
    always has a significant interest in seeing that legal
    36
    strictures are properly enforced and thus, in a real sense, the
    public always derives a ‘benefit’ when illegal private or
    public conduct is rectified. Both the statutory language
    (‘significant benefit’) and prior case law, however, indicate
    that the Legislature did not intend to authorize an award of
    attorney fees in every case involving a statutory violation.
    [Rather,] the Legislature contemplated that in adjudicating
    a motion for attorney fees under section 1021.5, a trial court
    would determine the significance of the benefit, as well as
    the size of the class receiving benefit, from a realistic
    assessment, in light of all the pertinent circumstances, of the
    gains which have resulted in a particular case.” (Woodland
    Hills Residents Assn., Inc. v. City Council (1979) 
    23 Cal.3d 917
    , 939-940; accord, Villarreal v. Gordon (2019) 
    44 Cal.App.5th 233
    , 240.) Given that the warnings in this case
    disserved Prop. 65’s purpose to inform the public of
    significant cancer risks (see Dowhal, 
    supra,
     
    32 Cal.4th at 934
    ; Nicolle-Wagner, supra, 230 Cal.App.3d at 661), they
    provided no significant benefit for purposes of the attorney
    fees statute. Accordingly, the trial court properly denied
    CERT’s motion for attorney fees.
    C. Section 998 Costs
    CERT contends the section 998 respondents’
    compromise offers were invalid because: (1) settlement offers
    in Prop. 65 cases can never be valid under section 998, as
    they require court approval; and (2) the relevant
    respondents’ offers included overly broad releases.
    37
    Assuming, without deciding, that section 998 applies to
    Prop. 65 claims, we agree that the offers here were invalid
    because they included overly broad releases. Accordingly,
    we reverse the trial court’s denial of CERT’s motion to tax
    costs.
    1. Background
    During the litigation, the section 998 respondents
    served CERT with statutory offers to compromise. Under
    the terms of the offers, these respondents were to pay CERT
    substantial amounts and post Prop. 65 warnings, with
    certain conditions. In return, CERT was to provide two
    kinds of releases. The first was a public release, requiring
    CERT, as a plaintiff suing “in the public interest,” to release
    the offerors from “all claims . . . as to any alleged violation of
    Proposition 65 that is or that could have been asserted in the
    [pre-suit] Notice or [complaint] based on the facts alleged
    therein.” The second release applied to CERT in “its
    individual capacity,” and required it to provide “a general
    release” of “all [c]laims of CERT . . . of any nature, character
    or kind, known or unknown, suspected or unsuspected,
    arising under Proposition 65 or for an alleged failure to
    provide warnings for exposures to acrylamide.” CERT
    rejected these compromise offers.
    After entry of judgment, the section 998 respondents
    filed memoranda of costs seeking to recover almost $700,000
    in post-offer costs. CERT moved to tax costs, challenging the
    validity of the statutory compromise offers and arguing,
    38
    inter alia, that the releases included in the offers were overly
    broad because they applied to claims outside the scope of the
    litigation “such that there would be no way to determine
    whether a judgment in the pending action is ‘more favorable’
    than the value of those claims.” The trial court denied
    CERT’s motion and awarded the requested post-offer costs.16
    2. Applicable Law
    “On a motion to strike or tax costs, ‘[t]he burden is on
    the offering party to demonstrate that the offer is valid
    under section 998.’ [Citations.] ‘The offer must be strictly
    construed in favor of the party sought to be bound by it.’
    [Citations.] ‘“We independently review whether a section
    998 settlement offer was valid. In our review, we interpret
    any ambiguity in the offer against its proponent.”’”
    (Khosravan v. Chevron Corp. (2021) 
    66 Cal.App.5th 288
    ,
    294-295.)
    Under section 998, “any party may serve an offer in
    writing upon any other party to the action to allow judgment
    to be taken or an award to be entered in accordance with the
    terms and conditions stated at that time.” (§ 998, subd. (b).)
    “If an offer made by a defendant is not accepted and the
    plaintiff fails to obtain a more favorable judgment,” the
    plaintiff must “pay the defendant’s costs from the time of the
    offer,” and the court has discretion to “require the plaintiff to
    16     On appeal, CERT has not provided a reporter’s transcript
    of the hearing on its motion to tax.
    39
    pay a reasonable sum to cover postoffer costs of the services
    of expert witnesses . . . .” (§ 998, subd. (c)(1).)
    Because section 998 requires a determination whether
    the offer’s terms were more favorable than the judgment, the
    offer must not include a release of claims beyond those
    involved in the litigation. (Ignacio v. Caracciolo (2016) 
    2 Cal.App.5th 81
    , 86-87 (Ignacio); see id. at 87 [“Requiring
    resolution of potential unfiled claims not encompassed by the
    pending action renders the offer incapable of valuation”].)
    Thus, in Ignacio, the court held a section 998 offer invalid
    because it went “well beyond the scope of the litigation,”
    requiring the release of “‘any and all claims’ the releasees
    may have against the releasors ‘whether now known or
    unknown, suspected or unsuspected, that have existed or
    may have existed or which do exist, or which hereinafter
    can, shall or may exist . . . .’” (Ignacio, supra, at 89.) The
    Ignacio court noted that the plaintiff-offeree had identified
    before the trial court a claim that was not involved in the
    pending litigation but would have been encompassed by the
    release. (Id. at 90.) Because the proposed release of
    extraneous claims made the offer incapable of valuation, the
    court concluded the offer was invalid for purposes of section
    998. (Ignacio, supra, at 87, 89-90.)
    Similarly, in Chen v. Interinsurance Exchange of the
    Automobile Club (2008) 
    164 Cal.App.4th 117
     (Chen), the
    court deemed an offer invalid because it required a “‘general
    release of all claims.’” (Id. at 122.) The court reasoned that
    the required release was at least ambiguous as to whether it
    40
    applied to a pending insurance claim outside the scope of the
    litigation, rendering the offer incapable of valuation. (Id. at
    122-123.)
    3. Analysis
    The individual-capacity general releases included in
    the section 998 respondents’ compromise offers were overly
    broad, as they encompassed claims beyond the scope of this
    litigation. As noted, those releases would have applied to
    “all Claims . . . known or unknown . . . arising under
    Proposition 65 or for an alleged failure to provide warnings
    for exposures to acrylamide.” While the release would have
    applied only to Prop. 65 claims, the section 998 respondents
    point to nothing in their language that would have limited
    them to the claims involved in CERT’s actions, and we see no
    such limitation. Because the releases extended beyond the
    scope of the litigation, they invalidated the compromise
    offers. (See Ignacio, supra, 2 Cal.App.5th at 86-87; Chen,
    supra, 164 Cal.App.4th at 122.)
    The section 998 respondents argue the general releases
    did not invalidate their statutory compromise offers for four
    reasons. First, they note that during the litigation, CERT
    approved other defendants’ section 998 offers containing the
    same releases. Citing no authority, the section 998
    respondents argue, “The fact that such releases were
    standard for CERT . . . supports the conclusion that CERT
    was not prejudiced by such provisions, and that they were an
    appropriate part of a proposed consent judgment under
    41
    Proposition 65.” However, the relevant question under
    section 998 is whether the offers allowed for a determination
    that the judgment was more favorable, not whether the
    offers “prejudiced” the offeree. Regardless of whether CERT
    accepted other flawed section 998 offers, these respondents’
    offers required the court to engage in an impracticable
    valuation of potential claims outside the scope of the
    litigation, and were therefore invalid. (See Ignacio, supra, 2
    Cal.App.5th at 87; Chen, supra, 164 Cal.App.4th at 122-123)
    Second, the section 998 respondents state that under
    Goodstein v. Bank of San Pedro (1994) 
    27 Cal.App.4th 899
    (Goodstein), a valid statutory compromise offer may include
    a general release. In Goodstein, however, the court
    concluded that a “general release” did not invalidate a
    statutory compromise offer after construing it to apply only
    to the litigation before it. (Goodstein at 907; accord, Ignacio,
    supra, 2 Cal.App.5th at 89 [“The rule to be taken from
    Goodstein is not that a ‘general release’ does not invalidate a
    section 998 offer; the rule is that a release of unknown
    claims arising only from the claim underlying the litigation
    itself does not invalidate the offer”].) We cannot similarly
    construe the releases here, which applied to “all [c]laims . . .
    under Prop. 65.”
    Third, the section 998 respondents contend that to
    establish that a release was overbroad, the offeree must
    identify a potential claim that would have been encompassed
    by the release but is beyond the scope of the litigation. They
    contend CERT failed to do so, both in the trial court and on
    42
    appeal. Assuming arguendo that such a requirement exists,
    no special effort is needed to identify a qualifying potential
    claim in this case. As discussed above, and as these
    respondents themselves argue in the context of summary
    judgment, CERT’s asserted claim involving exposure to
    acrylamide formed by additives in coffee was beyond the
    scope of its actions. Yet under the terms of the proposed
    general releases, this claim -- undoubtedly a claim under
    Prop. 65 -- would have been relinquished.17
    Finally, the section 998 respondents claim their offers,
    which included Prop. 65 warnings and substantial payments
    to CERT, “were clearly more favorable than the judgment of
    dismissal that CERT achieved.” But this assertion ignores
    claims beyond the scope of CERT’s actions that were to be
    released under the offers. The asserted claim involving
    17     The section 998 respondents suggest that CERT forfeited
    its arguments by failing to expressly identify a released claim
    beyond the scope of the litigation. To the extent this asserted
    failure triggers the forfeiture rule, we exercise our discretion to
    consider CERT’s contentions and the claim we have identified
    because this matter is subject to de novo review and the relevant
    claim was extensively discussed both below and on appeal in the
    context of summary judgment, providing the section 998
    respondents ample opportunity to address it. (See Husman v.
    Toyota Motor Credit Corp. (2017) 
    12 Cal.App.5th 1168
    , 1187
    [noting appellate courts’ discretion to consider matter that was
    not argued below but involves only legal question based on
    undisputed facts]; Jameson v. Desta (2009) 
    179 Cal.App.4th 672
    ,
    674, fn. 1 [exercising discretion to consider claim not raised in
    opening brief because respondent had not been deprived of
    opportunity to address issue].)
    43
    coffee additives was unaffected by the Coffee Regulation, and
    if found meritorious, could have yielded a significant reward
    for CERT, which would have been entitled to 25 percent of
    all penalties collected.18 Given that the proposed releases in
    the section 998 offers covered this and other potential
    claims, the trial court could not have determined that the
    offers were more favorable than the judgment. Thus, the
    offers were invalid for purposes of section 998, and the trial
    court erred in denying CERT’s motion to tax costs.
    18    As noted, a person who violates Prop. 65 is subject to civil
    penalties of up to $2,500 per day for each violation. (Health &
    Saf. Code, § 25249.7, subd. (b)(1).)
    44
    DISPOSITION
    The trial court’s orders granting summary judgment
    and denying attorney fees are affirmed. The order denying
    CERT’s motion to tax costs is reversed. The parties shall
    bear their own costs on appeal.
