    IN THE COURT OF APPEAL OF THE STATE OF CALIFORNIA
    THIRD APPELLATE DISTRICT
    (Plumas)
    ----
    DEPARTMENT OF FORESTRY AND FIRE                                                               C093352
    PROTECTION,
    (Super. Ct. No. CV0900505)
    Plaintiff and Appellant,
    v.
    EUNICE E. HOWELL et al.,
    Defendants and Respondents.
    This case returns to us after we previously ordered a remand with directions for
    further proceedings relating (primarily) to a postjudgment award of monetary discovery
    sanctions in favor of defendants Eunice E. Howell, individually and on behalf of
    Howell’s Forest Harvesting, and its employees, Kelly Crismon and J.W. Bush (Howell);
    Sierra Pacific Industries, Inc. (Sierra Pacific); W.M. Beaty and Associates (Beaty); and
    multiple landowners (Landowners, and collectively, defendants).
    In our prior opinion, we concluded that there was substantial evidence to support
    the trial court’s finding that monetary sanctions were warranted, but that the trial court
    1
    erred in the manner in which it imposed the sanctions. We remanded with directions for
    the trial court to reconsider the amount of monetary sanctions awarded to defendants “as
    a result of” plaintiff’s discovery abuses and to calculate an appropriate award of statutory
    costs for the prevailing party defendants.
    Plaintiff California Department of Forestry and Fire Protection (Cal Fire)
    challenges the award of monetary sanctions in the trial court’s decision on remand. It
    contends the trial court erred because it (1) failed to follow our remand instructions and
    essentially repeated the same mistakes it made previously, (2) applied the wrong standard
    of causation, (3) concluded that defendants were not required to file a motion to compel
    or seek redress for discovery abuses prior to requesting sanctions, and (4) made incorrect
    assumptions and additional errors in calculating the sanctions award. Cal Fire also
    challenges the trial court’s costs award.
    We agree with Cal Fire’s first two contentions and therefore reverse and remand
    (with directions) the part of the trial court’s order pertaining to the monetary sanctions
    award. We affirm the part of the order pertaining to the costs award.
    FACTS AND HISTORY OF THE PROCEEDINGS
    Cal Fire previously appealed from a judgment of dismissal (case No. C074879)
    and various postjudgment awards of fees, costs, and discovery sanctions (case No.
    C076008). (Department of Forestry & Fire Protection v. Howell (2017) 
    18 Cal.App.5th 154
    , overruled in part as stated in Presbyterian Camp & Conference Centers, Inc. v.
    Superior Court (2021) 
    12 Cal.5th 493
    , 516 (Howell).) We rely heavily on our prior
    opinion for the relevant facts and procedure, supplemented where necessary by the
    record.
    A.     Origin of the Moonlight Fire
    This case arises from the “Moonlight Fire,” a wildfire that ignited in Plumas
    County on September 3, 2007, and burned approximately 65,000 acres over the course of
    2
    several weeks. (Howell, supra, 18 Cal.App.5th at p. 162.) The fire started on property
    owned by the Landowners and managed by Beaty. (Id. at p. 164.) Sierra Pacific
    purchased standing timber on the property and contracted with Howell, a licensed timber
    operator, to conduct logging operations on the property. (Ibid.)
    Cal Fire and the United States Forest Service (USFS) jointly investigated the cause
    of the fire. (Howell, supra, 18 Cal.App.5th at p. 187.) In June 2009, Cal Fire and USFS
    released their nearly 300-page Origin and Cause Investigation Report (the Moonlight
    Report). The Moonlight Report concluded that the fire started when a bulldozer operated
    by Howell’s employees (J.W. Bush and Kelly Crismon) struck a rock or rocks, causing
    superheated metal fragments to splinter off and ignite surrounding forest litter. (Id. at
    pp. 163, 164; United States v. Sierra Pac. Indus., Inc. (9th Cir. 2017) 
    862 F.3d 1157
    ,
    1163.) The Report also faulted Howell’s employees for allowing the fire to spread by
    leaving the area without inspecting for signs of fire. (Ibid.)
    B.     The Moonlight Fire lawsuits
    In 2009 and 2010, Cal Fire, Grange Insurance Association, and an assortment of
    private landowners filed lawsuits against defendants seeking recovery of fire suppression
    and investigation costs and other monetary damages in the tens of millions of dollars.
    (Howell, supra, 18 Cal.App.5th at pp. 163, 175, fn. 12, 202.) In a separate but related
    case, the federal government filed suit against the same defendants for its damages and
    fire suppression costs. (United States v. Sierra Pac. Indus., Inc., supra, 862 F.3d at
    pp. 1163-1164.) Potential damages in the federal action exceeded $800 million. (Id. at
    p. 1164.)
    Over the ensuing four years, the parties engaged in extensive discovery and
    pretrial motions in the consolidated state court action and concurrent federal action.
    (Howell, supra, 18 Cal.App.5th at p. 165.) Discovery included more than 400 days of
    depositions, 428 requests for production, 1163 special interrogatories, and 435 requests
    3
    for admission. There were more than 35 discovery motions, nearly 100 motions in
    limine, and two cross motions for summary judgment.
    In July 2012, the parties settled the federal action, with defendants collectively
    agreeing to pay $55 million and transfer 22,500 acres of land to the federal government.
    (United States v. Sierra Pac. Indus., Inc., supra, 862 F.3d at pp. 1164-1165.) The state
    cases continued after settlement of the federal case. (Id. at p. 1165.)
    In July 2013, less than a week before trial in the state court actions, the trial court
    ruled that none of the plaintiffs could establish a prima facie case and entered a judgment
    of dismissal in favor of the defendants based on Cottle v. Superior Court (1992)
    
    3 Cal.App.4th 1367
     (Cottle). (Howell, supra, 18 Cal.App.5th at pp. 165, 170-171.) The
    trial court also granted an oral motion for judgment on the pleadings as to Cal Fire’s
    claims against Sierra Pacific, Beaty, and Landowners. (Howell, at p. 175.)
    C.     The postjudgment motions
    After the judgment of dismissal, defendants filed motions for attorney fees,
    expenses, and discovery sanctions. (Howell, supra, 18 Cal.App.5th at p. 166.) The
    motions were based on multiple, overlapping grounds. Defendants sought monetary and
    terminating sanctions under two separate sources of authority: section 2023.030 of the
    Civil Discovery Act (§ 2016.010 et seq.) and the trial court’s inherent common law
    authority. (Howell, at pp. 190-191.) (Further undesignated statutory references are to the
    Code of Civil Procedure.) Defendants moved for attorney fees as “prevailing parties” on
    a contractual basis (Civ. Code, § 1717) and as private attorneys general (§ 1021.5).
    (Howell, at p. 198.) Defendants also moved under section 2033.420, subdivision (a) to
    recover costs incurred in disproving Cal Fire’s denial of certain requests for admission.
    (Howell, at pp. 166, 202.)
    In a postjudgment order, the trial court ruled that defendants are entitled to recover
    their requested fees, expenses, and sanctions. (Howell, supra, 18 Cal.App.5th at pp. 166-
    4
    167.) In reaching this conclusion, the court found that Cal Fire had engaged in multiple
    and repeated discovery abuses. The trial court specifically described seven “examples”
    of discovery abuses committed by Cal Fire, namely: (1) false testimony by investigators
    Joshua White (White) and David Reynolds (Reynolds) regarding concealment of
    photographs of a white flag, a “fire origin” sketch, and other evidence that appeared to
    place the point of origin of the fire in a slightly different location (about 10 feet away)
    from that described in the Moonlight Report; (2) White’s destruction of the
    contemporaneous field notes he prepared during his investigation; (3) the Moonlight
    Report’s false summary of an interview with Howell employee J.W. Bush; (4) the
    Moonlight Report’s omission of an “unsolicited false alibi” from Ryan Bauer, who had
    been cutting firewood in the area; (5) the Moonlight Report’s omission of alleged
    employee misconduct at the closest federal lookout, known as the Red Rock lookout
    tower; (6) a false statement in the Moonlight Report that a Howell bulldozer ignited the
    Lyman Fire; and (7) Cal Fire’s failure to produce documents responsive to a request for
    production relating to the “Wildland Fire Investigation Training and Equipment Fund”
    (the WiFITER fund), which defendants believed to be an illegal account that provided a
    financial incentive to hold defendants responsible for the fire. (Howell, at pp. 166, 185-
    189; United States v. Sierra Pac. Indus., Inc., supra, 862 F.3d at pp. 1164, 1170; United
    States v. Sierra Pac. Indus. (E.D.Cal. 2015) 
    100 F. Supp. 3d 948
    , 967.) The trial court’s
    order made clear that these were merely “examples” of Cal Fire’s discovery abuses and
    not intended to be an exhaustive list of its transgressions.
    In a separate order, the court found that Cal Fire’s misconduct was “so pervasive
    that it would serve no purpose for the [c]ourt to attempt to recite it all . . . .” The court
    indicated that additional examples of Cal Fire’s discovery abuses could be found in
    defendants’ briefing. The court specifically referenced, without analysis, two previously-
    filed pleadings—one by Sierra Pacific and the other by Beaty—listing almost four dozen
    “examples” of alleged discovery abuses.
    5
    In awarding terminating sanctions, “[t]he trial court found that Cal Fire’s
    ‘ “willful,” ’ ‘repeated and egregious’ misuses of the discovery process ‘permeated nearly
    every single significant issue in this case’ to an extent that ‘ “threatened the integrity of
    the judicial process” ’ and made it implausible that defendants could ever receive a fair
    trial. The trial court further stated that ‘Cal Fire’s actions in initiating, maintaining, and
    prosecuting this action, to the present time [postjudgment] [are] corrupt and tainted. . . .
    [C]al Fire failed to comply with discovery orders and directives, destroyed critical
    evidence, failed to produce documents it should have produced months earlier, and
    engaged in a systematic campaign of misdirection with the purpose of recovering money
    from Defendants.’ ” (Howell, supra, 18 Cal.App.5th at p. 197.)
    In awarding monetary sanctions, the court found that all of defendants’ litigation
    expenses were “inextricably intertwined,” in one way or another, with the falsehoods and
    omissions in the Moonlight Report, which Cal Fire injected into the litigation through its
    July 2010 discovery responses. (Howell, supra, 18 Cal.App.5th at p. 184.) Thus, the trial
    court found that “Cal Fire’s discovery abuses from July 2010 forward were the cause of
    all defense expenses incurred from that point forward.” The trial court collectively
    awarded the defendants monetary sanctions totaling more than $28 million, representing
    all (or virtually all) of the attorney fees, expert fees, and other expenses incurred in both
    the federal and state court actions. (Howell, at pp. 183, 194.) Specifically, the court
    awarded $21,100,723.20 to Sierra Pacific; $6,146,901.41 to Beaty/Landowners; and
    $1,571,741.28 to Howell. (Id. at pp. 183-184.)
    D.     The first appeal
    Plaintiffs appealed the judgment of dismissal, the postjudgment awards, and the
    trial court’s costs award. (Howell, supra, 18 Cal.App.5th at pp. 163-164, 202-203.) On
    appeal, we (1) affirmed the trial court’s order granting the motion for judgment on the
    pleadings, (2) reversed the judgment of dismissal based on Cottle, supra, 
    3 Cal.App.4th
                                6
    1367, (3) affirmed the court’s imposition of terminating sanctions, and (4) reversed the
    attorney fee awards. (Howell, at pp. 203-204.)
    Regarding the monetary sanctions award, we affirmed the trial court’s conclusion
    “that monetary sanctions were warranted” in light of Cal Fire’s discovery violations.
    (Howell, supra, 18 Cal.App.5th at p. 193.) We discussed each of the seven examples of
    discovery abuse identified by the trial court, and analyzed whether the findings were
    supported by substantial evidence. (Ibid.) We concluded that two of the seven
    findings—the omission of information related to the Red Rock lookout and the omission
    of Bauer’s alibi—were not supported by substantial evidence. (Ibid.) But we concluded
    there was substantial evidence to support the other findings of discovery misuse: White’s
    untruthful or evasive deposition testimony regarding the white flag; spoliation of White’s
    field notes; the Moonlight Report’s false summary of Bush’s interview statement; the
    Moonlight Report’s incorporation of the false Lyman Fire report; and the delayed
    production of responsive WiFITER fund documents. (Ibid.) We did not decide whether
    any of the other alleged discovery abuses included in defendants’ lists were supported by
    substantial evidence.
    Although we upheld the conclusion that monetary sanctions were warranted, we
    took issue with the manner in which the trial court imposed the sanctions. (Howell,
    supra, 18 Cal.App.5th at pp. 184, 193-194.) We rejected the trial court’s reasoning that
    all expenses incurred since the inception of litigation could be imposed as sanctions
    because they were “inextricably intertwined” with the falsehoods and omissions in the
    Moonlight Report. (Id. at p. 194.) We held that under section 2023.030 the trial court
    was statutorily limited to awarding only those “ ‘reasonable expenses, including
    attorney’s fees, incurred . . . as a result of’ a misuse of the discovery process.” (Id. at
    p. 194.)
    We concluded that the motions at issue provided “ample evidence” of when fees
    were incurred by defendants, but did “little to explain how those fees were incurred as a
    7
    result of Cal Fire’s discovery abuses.” (Howell, supra, 18 Cal.App.5th at p. 195.)
    Therefore, we were “unable to ascertain from the record which attorney fees and expert
    fees and expenses were incurred as a result of the discovery misuses for which we have
    concluded there is substantial evidence in the record to support imposition.” (Ibid.) We
    reversed the trial court’s award of monetary sanctions and remanded the matter for the
    trial court to conduct a hearing to redetermine the reasonable expenses, including
    attorney’s fees, incurred by defendants as a result of Cal Fire’s discovery violations. (Id.
    at pp. 195, 204; accord, Dep’t of Forestry & Fire Prot. v. Superior Court (Oct. 31, 2018,
    C087374) [nonpub. opn.] [
    2018 Cal. App. Unpub. LEXIS 7363
    , at pp. *10-14] (Howell
    II).)
    We reversed the trial court’s award of costs to Howell, and remanded for a new
    calculation of costs to be awarded to Sierra Pacific, Beaty, and Landowners under
    sections 1032 and 1033.5 for defending against Cal Fire’s action. (Howell, supra,
    18 Cal.App.5th at pp. 164, 183, 203-204.)
    E.    Proceedings on remand
    On remand, the parties submitted extensive additional briefing on the reasonable
    expenses incurred by defendants as a result of Cal Fire’s discovery abuses. To meet their
    burden, defendants first prepared a nonexhaustive list of Cal Fire’s discovery abuses.
    Sierra Pacific, for example, identified 38 alleged discovery abuses, sorted into four
    categories: untruthful or evasive deposition testimony, false and evasive discovery
    responses, disobeyed discovery orders, and spoliation.
    To establish a causative connection between defendants’ reasonable fees and
    expenses and Cal Fire’s alleged discovery abuses, each defendant filed a declaration with
    a chronological, month-by-month summary of the total time spent and fees/expenses
    performing various tasks. Counsel then described, in a generalized way, how the tasks
    8
    were a result of Cal Fire’s discovery abuses. The resulting declarations totaled nearly
    800 pages.
    Based on the declarations, defendants suggested different approaches for how the
    trial court could determine a reasonable award of monetary sanctions. For example,
    defendants argued the court could award all fees and expenses incurred after March 5,
    2010—the date of the first discovery abuse—due to the pervasive nature of Cal Fire’s
    discovery abuses, which required defendants to uncover and expose Cal Fire’s “false”
    and “fraudulent” narrative. Alternatively, Sierra Pacific and Beaty/Landowners argued
    that the trial court could award all fees and expenses after March 2010, less deductions
    for time spent working on certain tasks that were more “attenuated.” (Howell, in
    contrast, claimed to be seeking only fees and expenses “directly” related to Cal Fire’s
    discovery abuses.)
    Cal Fire argued that the trial court should consider only the discovery abuses
    found to be supported by substantial evidence in Howell, and that the amount of the
    award should be limited to reasonable expenses “directly related” to those abuses. Cal
    Fire argued that the award should not include fees and costs incurred in generally
    defending the case. Cal Fire further argued that any sanctions award must be tied to a
    specific discovery motion, such as a motion to compel.
    In October 2020, after a two-day hearing, the trial court issued its decision on
    remand. Adopting a “substantial factor” test to determine causation, the trial court
    concluded that virtually all the fees and expenses incurred by defendants were “a result
    of” Cal Fire’s sanctionable discovery misconduct.
    In applying the “substantial factor” test, the court declined to link specific fees and
    expenses to any particular instances of discovery misconduct, or to limit Cal Fire’s
    discovery misconduct to the “examples” affirmed in Howell. Instead, the court broadly
    found that “Cal Fire’s discovery abuses and misuses extend[] far beyond those mentioned
    in [Howell]”, and were so pervasive throughout the litigation that it could not “imagine
    9
    any expenditure the defendants incurred as a result of Cal Fire’s numerous deliberate and
    egregious discovery abuses and misuses that could not also be characterized as fees and
    expenses for generally defending the case.” Additionally, the court concluded that
    “defendants were not required to file a motion to compel or seek redress for any
    discovery abuses or misuses prior to requesting monetary sanctions.”
    The court ultimately awarded Sierra Pacific, Beaty, and Landowners all their
    requested fees and expenses from March 2010 (the date defendants received the
    Moonlight Report as a discovery response) through July 2013 (the date of the pre-trial
    hearings), excluding only (1) fees incurred by Sierra Pacific’s associate counsel and
    paralegals, (2) certain expenses associated with the preparation of demonstrative visual
    exhibits (which previously had been sought as litigation costs), and (3) certain fees and
    expenses incurred in respect to the federal action. The court reasoned that “all of the
    defendant’s expert fees and a significant portion of the defendant’s attorneys’ fees . . .
    were [incurred] as a result of Cal Fire’s sanctionable conduct of misusing and abusing the
    discovery process pursuant to CCP section 2023.030.” The court did not remove any
    expenses incurred in the state cases from March 5, 2010, through July 2013, due to lack
    of causation.
    The court awarded Howell all requested attorney and expert fees and expenses
    incurred from March 2010 forward, including fees and expenses incurred after July 2013.
    It is not clear whether the differential treatment of Howell was intentional.
    The trial court awarded $1,384,145 in monetary sanctions to Howell;
    $8,621,480.63 in sanctions to Sierra Pacific; and $2,681,816.68 in sanctions to
    Beaty/Landowners. The trial court also awarded $1,214,296.93 in costs to Sierra Pacific,
    and $299,798.47 in costs to Beaty/Landowners.
    Cal Fire filed a timely notice of appeal on December 17, 2020.

    DISCUSSION
    Cal Fire challenges the trial court’s sanctions award on several grounds. Cal Fire
    argues that the trial court abused its discretion because it (1) failed to follow this court’s
    remand instructions, (2) applied the wrong legal standard of causation, (3) awarded
    monetary sanctions for discovery misconduct without a predicate motion to compel, and
    (4) made incorrect assumptions and other mistakes in determining the amount of the
    award. We agree with the first two contentions and reverse and remand for further
    proceedings on that basis. We explain below.
    I
    Abuse of Discretion
    Cal Fire argues that the trial court’s award of sanctions must be reversed because
    the trial court applied the wrong standard of causation and failed to follow our remand
    instructions. We agree.
    A.     Background law
    Before addressing the merits of Cal Fire’s claim, we begin with a brief discussion
    of the legal principles governing an award of monetary sanctions.
    There are multiple sources of authority for sanctions under California law. The
    type of sanctions available and the procedure for imposing them depends on the
    circumstances justifying the award. For example, section 128.5 authorizes sanctions for
    actions or tactics that are made in bad faith, frivolous, or solely intended to cause
    unnecessary delay. (Levy v. Blum (2001) 
    92 Cal.App.4th 625
    , 635; § 128.5, subd. (a).)
    However, by its terms, section 128.5 does not apply to discovery requests, responses,
    objections, and motions. (§ 128.5, subd. (e).)
    Discovery sanctions are governed by the Civil Discovery Act. (§ 2023.030.)
    Under section 2023.030 of the Act, a court may sanction “anyone engaging in conduct
    11
    that is a misuse of the discovery process.” (§ 2023.030.) Misuses of the discovery
    process include, but are not limited to, (1) failing to respond to an authorized method of
    discovery, (2) making an evasive response to discovery, (3) disobeying a court order to
    provide discovery, (4) altering or destroying evidence in response to (or in anticipation
    of) a discovery request, and (5) willfully providing a false discovery response.
    (§ 2023.010; Kwan Software Engineering, Inc. v. Hennings (2020) 
    58 Cal.App.5th 57
    , 74
    (Kwan); Saxena v. Goffney (2008) 
    159 Cal.App.4th 316
    , 333-334; Cedars-Sinai Medical
    Center v. Superior Court (1998) 
    18 Cal.4th 1
    , 12; Sherman v. Kinetic Concepts,
    Inc. (1998) 
    67 Cal.App.4th 1152
    , 1162 (Sherman).)
    The discovery statutes authorize a range of penalties for conduct amounting to
    discovery misuse, including monetary, issue, evidence, and terminating sanctions.
    (Cornerstone Realty Advisors, LLC v. Summit Healthcare REIT, Inc. (2020)
    
    56 Cal.App.5th 771
    , 790 (Cornerstone); § 2023.030, subds. (a)-(e).) The statutes
    governing each particular discovery method identify the types of sanctions that are
    available for a given discovery abuse. (London v. Dri-Honing Corp. (2004)
    
    117 Cal.App.4th 999
    , 1004-1007; New Albertsons, Inc. v. Superior Court (2008)
    
    168 Cal.App.4th 1403
    , 1422-1423.) The most common sanction for a misuse of
    discovery is a monetary sanction, which is authorized in the context of nearly every
    proceeding under the Civil Discovery Act. (Cal. Forms of Pleading and Practice (2022)
    ch. 192, Discovery: Sanctions for Discovery Misuse, § 192.15; Hogan & Weber, Cal.
    Civil Discovery (2021) ch. 15, § 15.4; Doppes v. Bentley Motors, Inc. (2009)
    
    174 Cal.App.4th 967
    , 992.)
    Section 2023.030, subdivision (a) of the Civil Discovery Act delineates the trial
    court’s authority to issue monetary sanctions. (Kwan, supra, 58 Cal.App.5th at p. 73.) It
    provides that the court may impose a monetary sanction ordering that one engaging in
    misuse of the discovery process pay the reasonable expenses incurred “as a result of” that
    conduct. (§ 2023.030, subd. (a).)
    12
    Although a trial court has broad discretion in setting the amount of a monetary
    sanction, the court must exercise its discretion in a manner consistent with the underlying
    purpose of the law. (Cornerstone, supra, 56 Cal.App.5th at p. 789.) The purpose of
    discovery sanctions is to compel disclosure of discoverable information, prevent abuse of
    the discovery process, and protect the interests of the party entitled to the discovery. (In
    re Marriage of Economou (1990) 
    224 Cal.App.3d 1466
    , 1475; Do v. Superior Court
    (2003) 
    109 Cal.App.4th 1210
    , 1213; Siry Investment, L.P. v. Farkhondehpour (2020)
    
    45 Cal.App.5th 1098
    , 1117, review granted July 8, 2020, S262081.) A court may use
    monetary sanctions to compensate a victim for the harm done by the discovery abuse, but
    the court cannot use sanctions to punish the offending party. (Williams v. Russ (2008)
    
    167 Cal.App.4th 1215
    , 1223; Doppes v. Bentley Motors, Inc., supra, 174 Cal.App.4th at
    p. 992; McGinty v. Superior Court (1994) 
    26 Cal.App.4th 204
    , 210.) In choosing a
    sanction, the trial court should attempt to “tailor the sanction” to the discovery abuse.
    (Doppes v. Bentley Motors, Inc., supra, at p. 992.) “ ‘Discovery sanctions “should be
    appropriate to the dereliction, and should not exceed that which is required to protect the
    interests of the party entitled to but denied discovery.” ’ [Citation.]” (Doppes v. Bentley
    Motors, Inc., supra, 174 Cal.App.4th at p. 992.) The sanction imposed should not
    provide a windfall, putting the prevailing party in a better position than if it had obtained
    the requested discovery. (Williams, supra, at p. 1223; Kwan, supra, 58 Cal.App.5th at
    pp. 74-75.)
    B.     Standard of review
    We review a trial court’s sanctions order under the deferential abuse of discretion
    standard. (Kwan, supra, 58 Cal.App.5th at p. 73.) Under this standard, the trial court’s
    findings of fact are reviewed for substantial evidence, its conclusions of law are reviewed
    de novo, and its application of the law to the facts is reversible only if arbitrary and
    13
    capricious. (Ibid; Park v. Law Offices of Tracey Buck-Walsh (2021) 
    73 Cal.App.5th 179
    ,
    188.)
    However, when an appellate court reverses with directions, those directions “are
    binding on the trial court and must be followed.” (Butler v. Superior Court (2002)
    
    104 Cal.App.4th 979
    , 982.) Action which does not conform to the directions is
    unauthorized and void. (Ibid; Ayyad v. Sprint Spectrum, L.P. (2012) 
    210 Cal.App.4th 851
    , 859.) The remittitur directions are contained in the dispositional language of the
    prior opinion, which must be construed in conjunction with the opinion as a whole.
    (Ayyad v. Sprint Spectrum, L.P., supra, 210 Cal.App.4th at p. 859.) Whether the trial
    court correctly interpreted the directions is an issue of law, subject to de novo review.
    (Rincon EV Realty LLC v. CP III Rincon Towers, Inc. (2019) 
    43 Cal.App.5th 988
    , 997.)
    C.     Failure to Follow Remand Instructions
    In this case, we conclude that the trial court abused its discretion by failing to
    comply with our remand instructions in Howell, supra, 
    18 Cal.App.5th 154
    .
    When initially moving for sanctions, defendants argued that Cal Fire’s discovery
    misconduct was so pervasive and appalling—infecting virtually every aspect of the
    litigation—that they should recover all their defense fees and costs as sanctions. The trial
    court agreed. The court found that all of defendants’ litigation expenses were
    “inextricably intertwined,” in one way or another, with the falsehoods and omissions in
    the Moonlight Report, which were injected into the litigation through Cal Fire’s
    discovery responses. (Howell, supra, 18 Cal.App.5th at pp. 184, 194.) Thus, the court
    awarded defendants all their claimed expenses from the inception of the litigation,
    including expenses incurred prior to Cal Fire’s discovery abuses. (Id. at pp. 193-194.)
    In reversing that order, we rejected the notion that defendants could be awarded all
    their fees and expenses merely because they showed Cal Fire’s investigation was flawed
    or that the Moonlight Report was (in certain respects) deficient or false. (Howell, supra,
    14
    18 Cal.App.5th at pp. 194-195.) We noted that, unlike a motion for sanctions under
    section 128.5, a motion for monetary sanctions under section 2023.030 does not permit a
    trial court to order a party to pay reasonable expenses incurred as a result of frivolous or
    bad-faith actions. (Id. at p. 195.) We held that under section 2023.030, the trial court
    was statutorily limited to awarding only those “ ‘reasonable expenses, including
    attorney’s fees, incurred . . . as a result of’ a misuse of the discovery process.” (Id. at
    p. 194.) And we concluded that it was an abuse of discretion for the trial court to award
    any sanctions not authorized by section 2023.030, including expenses incurred prior to
    Cal Fire’s misuses of the discovery process. (Ibid.)
    Our ruling was not solely concerned with the timing of when the expenses were
    incurred. If it were, there would have been no need for us to remand for further
    proceedings. We could have simply modified the judgment to disallow any expenses
    incurred prior to Cal Fire’s discovery misconduct and left the remainder of the award
    intact. Instead, we held that it was an abuse of discretion for the trial court to award fees
    incurred prior to Cal Fire’s misuses of the discovery process “and any fees that were not
    the result of those misuses.” (Howell, supra, 18 Cal.App.5th at p. 194, italics added.)
    Because we were unable to ascertain from the record which expenses were incurred as a
    result of discovery misuses for which there is substantial evidence in the record, we
    remanded the matter to the trial court for further hearing, with instructions to determine
    the reasonable expenses incurred as a result of Cal Fire’s misuses of the discovery
    process. (Id. at p. 195; see also Howell II, supra, C087374 [
    2018 Cal. App. Unpub. LEXIS 7363
    , at pp. *9-13].)
    On remand, the trial court again concluded that Cal Fire’s discovery abuses were
    the cause of all defense expenses incurred in the litigation. The trial court ruled that from
    March 5, 2010 forward, Cal Fire misused the discovery process by repeatedly providing
    the Moonlight Report as a verified response to discovery, even though it contained false
    and misleading statements. It stated: “To find that the defense should have treated any
    15
    portion of the Moonlight [R]eport as credible . . . when the defense continued to uncover
    omissions . . . and false statements in the report, and realize the author of the report was
    untruthful and evasive in his deposition testimony and committed spoliation of
    evidence[,] would defy common sense.” Thus, the trial court awarded all reasonable fees
    and expenses incurred in defending the case, from the time Cal Fire first provided the
    Moonlight Report as a verified discovery response (March 5, 2010) through the date of
    the pre-trial hearings (July 2013). The court expressly stated that it could not “imagine
    any expenditure the defendants incurred as a result of Cal Fire’s numerous deliberate and
    egregious discovery abuses and misuses that could not also be characterized as fees and
    expenses for generally defending the case.”
    As a result, the trial court’s award included numerous fees and expenses that have
    no apparent causal connection to any discovery violation, such as fees and costs
    defendants incurred in responding to Cal Fire’s discovery, responding to motions brought
    and won by Cal Fire, researching insurance coverage issues, attending case management
    conferences, and preparing for trial. The court made no effort to identify any specific
    discovery misuses (other than the ones previously described in Howell) or to explain how
    any of the fees incurred by defendants were linked to Cal Fire’s discovery abuses, except
    in the general sense that defendants were required to “investigate and unravel” false or
    misleading statements in the Moonlight Report or other discovery responses.
    As we explained in Howell, monetary discovery sanctions are not intended to
    compensate victims for expenses incurred as a result of bad-faith actions. (Howell,
    supra, 18 Cal.App.5th at p. 195.) Nor are they intended to be a broad exception to the
    general rule that attorney’s fees are not recoverable by the prevailing party. Monetary
    sanctions are intended to protect the interests of the party entitled to the discovery and,
    consistent with this purpose, they are limited to the reasonable expenses incurred as a
    result of discovery violations. (Siry Investment, L.P. v. Farkhondehpour, supra,
    45 Cal.App.5th at p. 1117, review granted.)
    16
    Here, under the guise of awarding monetary sanctions for discovery abuses, the
    trial court has awarded defendants their fees and expenses for generally defending the
    case. The court essentially accepted defendants’ argument that Cal Fire’s discovery
    abuses at the outset of the case—the false/misleading statements in the Moonlight Report
    and the destruction of White’s field notes—drove the entire defense and that, because the
    discovery misuse was pervasive, essentially everything the defendants did was
    recoverable as “fruit of the poisonous tree.”    This was little more than a variation of the
    reasoning, rejected in Howell, that all defense expenses were inextricably intertwined
    with the falsehoods and omissions in the Moonlight Report.
    The trial court’s decision is inconsistent with our instructions. And because the
    trial court failed to follow our instructions, we are again unable to ascertain from the
    record which fees and expenses were incurred as a result of discovery misuses for which
    there is substantial evidence in the record to support imposition. Accordingly, we reverse
    the part of the court’s order pertaining to the monetary sanctions award and remand with
    directions for the court to determine the reasonable expenses incurred as a result of
    misuses of the discovery process.
    D.     Wrong standard of causation
    Cal Fire argues that the trial court also abused its discretion by applying the
    substantial factor test of causation. Again, we agree.
    The principles governing statutory construction are well established. “ ‘Our
    fundamental task in construing a statute is to ascertain the intent of the lawmakers so as
    to effectuate the purpose of the statute. [Citation.] We begin by examining the statutory
    language, giving the words their usual and ordinary meaning. [Citation.] If there is no
    ambiguity, then we presume the lawmakers meant what they said, and the plain meaning
    of the language governs. [Citations.] If, however, the statutory terms are ambiguous,
    then we may resort to extrinsic sources, including the ostensible objects to be achieved
    17
    and the legislative history. [Citation.]’ ” (Council of San Benito County Governments v.
    Hollister Inn, Inc. (2012) 
    209 Cal.App.4th 473
    , 488.) “ ‘In the end, we “ ‘must select the
    construction that comports most closely with the apparent intent of the Legislature, with a
    view to promoting rather than defeating the general purpose of the statute, and avoid an
    interpretation that would lead to absurd consequences.’ ” ’ [Citation.]” (Li v. Superior
    Court (2021) 
    69 Cal.App.5th 836
    , 856.) We are not bound by the trial court’s
    conclusions because the interpretation of a statute is a question of law, which we review
    de novo. (Council of San Benito County Governments v. Hollister Inn, Inc., supra, at
    pp. 488-489.)
    The statutory language at issue limits monetary sanctions for discovery misuse to
    the “reasonable expenses, including attorney’s fees, incurred by anyone as a result of that
    conduct.” (§ 2023.030, subd. (a), italics added.) There is no dispute that the phrase “as a
    result of” connotes an element of causation, but the parties disagree as to what test of
    causation should apply.
    Defendants argue, as they did below, that the substantial factor test should apply.
    “ ‘The substantial factor standard is a relatively broad one, requiring only that the
    contribution of the individual cause be more than negligible or theoretical.’ [Citation.]
    Thus, ‘a force which plays only an “infinitesimal” or “theoretical” part in bringing about
    injury, damage, or loss is not a substantial factor’ [citation], but a very minor force that
    does cause harm is a substantial factor [citation].” (Bockrath v. Aldrich Chemical
    Co. (1999) 
    21 Cal.4th 71
    , 79; 1 CACI No. 430.) Under the substantial factor test,
    defendants contend they merely needed to show that Cal Fire’s discovery misuses were a
    substantial factor in causing the defense expenses, even if discovery misconduct was not
    the sole or even predominant cause of such expenses.
    Cal Fire argues that a traditional tort standard of causation is inappropriate here.
    Cal Fire contends that the purposes underlying the discovery statutes, and decisional
    authorities, establish that a monetary sanction under section 2023.030 must be limited to
    18
    reasonable expenses “directly related” to the misuse and “necessary to compel
    compliance.”
    We agree with Cal Fire that the trial court erred by applying the substantial factor
    test. As discussed, a monetary discovery sanction is intended to be compensatory rather
    than punitive in nature. (See Part I.A, p. 13, ante.) A court may use monetary sanctions
    to redress the harm caused by the misuse of discovery, but the sanction may not be used
    to punish the offending party or put the prevailing party in a better position than if it had
    obtained the requested discovery. (Ibid.) If an award includes fees or expenses that
    would have been incurred even without the misconduct, then it has crossed the boundary
    from compensation to punishment, putting the prevailing party in a better position than if
    it had obtained the requested discovery at the outset. Thus, we conclude the statute
    demands a direct causal relationship between the discovery violation(s) and the expenses
    incurred.
    Our interpretation is buttressed by the cases that have addressed causation in the
    context of monetary sanctions. Such cases have held that the amount of a monetary
    sanction award should reflect the actual fees and costs incurred as a result of the
    misconduct, which is usually the amount spent or incurred to obtain compliance with a
    discovery request. (See In re Marriage of Niklas (1989) 
    211 Cal.App.3d 28
    , 37-38;
    Ghanooni v. Super Shuttle (1993) 
    20 Cal.App.4th 256
    , 262-263.) In contrast, trial courts
    have declined to award expenses when the moving party cannot show the expenses were
    caused by the misconduct or when the expenses would have been incurred even without
    the misconduct. (Cornerstone, supra, 56 Cal.App.5th at pp. 795, 797; Argaman v.
    Ratan (1999) 
    73 Cal.App.4th 1173
    , 1179 [concluding that a monetary discovery sanction
    under former section 2023 may include attorney’s fees and other reasonable expenses
    “directly related” to the discovery misuse]; accord, 27B Cal.Jur.3d (2022) Discovery and
    Depositions, § 335; Thomas, Cal. Civil Courtroom Handbook & Desktop Reference
    (2021 ed.), ch. 25, Sanctions and Contempt, § 25:36; see also Baddie v. Berkeley
    19
    Farms (9th Cir. 1995) 
    64 F.3d 487
    , 490 [expenses are incurred “as a result of the
    removal” under 
    28 U.S.C. § 1447
     only if they are incurred as a direct result of removal,
    and would not have been incurred had the case remained in state court]; Avitts v. Amoco
    Prod. Co. (5th Cir. 1997) 
    111 F.3d 30
    , 32 [same].)
    We refuse to treat section 2023.030 as a surrogate for section 128.5, or to
    transform it into a broad exception to the default rule that each party must bear its own
    attorney’s fees. Thus, we conclude the trial court erred by applying a substantial factor
    test of causation and reverse and remand the monetary sanctions award on this basis as
    well. (This renders it unnecessary for us to consider Cal Fire’s arguments that the court
    made “incorrect assumptions and harmful mistakes” in its decision.)
    E.     Guidance on remand
    For guidance on remand, we make the following observations. First, defendants
    may not recover as monetary sanctions all the fees and expenses they incurred defending
    the case solely because they defeated Cal Fire’s claims, showed that Cal Fire’s
    investigation was flawed, or established that the Moonlight Report was (in some manner)
    deficient or false. (Howell, supra, 18 Cal.App.5th at pp. 194-195.) Defendants are
    limited to recovering expenses incurred as a result of discovery violations. (Id. at p. 195;
    accord, Cornerstone, supra, 56 Cal.App.5th at pp. 797-798 [denying as too attenuated
    defendants’ theory that they would not have had to prepare for trial if plaintiffs did not
    conceal evidence during discovery].)
    Second, the trial court must identify the specific discovery misuses upon which the
    award is based. We acknowledge that detailed findings are not usually required for
    issuance of sanctions in routine discovery disputes. (Cal. Shellfish v. United Shellfish
    Co. (1997) 
    56 Cal.App.4th 16
    , 26.) However, those disputes generally involve the
    mandatory imposition of monetary sanctions against a party who unsuccessfully makes or
    opposes a motion to compel a specific answer or production under a discovery statute. In
    20
    such a scenario, there is no question as to the conduct constituting the grounds for
    imposing the sanctions. This case is different. Here, there is neither a mandate for
    sanctions nor any clear delineation of the specific acts upon which the requested
    sanctions are based. Instead, defendants filed post-judgment motions seeking to recover
    all (or virtually all) defense expenses based on generalized accusations of “pervasive”
    discovery abuses, supported only by a vague and fluctuating list of “examples”—many of
    which have no discernable connection to any discovery violation.
    Under the unique circumstances of this case, principles of due process and
    effective appellate review require that the trial court’s order delineate the specific misuses
    of discovery upon which the award is based. (See First City Properties v.
    Macadam (1996) 
    49 Cal.App.4th 507
    , 515-516; Caldwell v. Samuels Jewelers (1990)
    
    222 Cal.App.3d 970
    , 978, superseded by statute on other grounds as stated in County of
    Monterey v. Mahabir (1991) 
    231 Cal.App.3d 1650
    , 1653; see also §§ 128.5, subd. (c),
    177.5.)
    Third, once the court has identified the specific misuses of discovery justifying the
    award, the court must determine which fees and expenses were incurred as a result of
    those discovery misuses. The record must be sufficient to explain how the fees and
    expenses were incurred as a result of the discovery misuses to which they relate.
    (Howell, supra, 18 Cal.App.5th at p. 195.) For example, if the trial court found Cal Fire
    misused the discovery process by relying on a fraudulent statement in the Moonlight
    Report, the record must explain how and when defendants discovered that the statement
    was fraudulent, and the fees and expenses necessary to compensate them for the
    discovery violation. Perfection is not required; the court may use estimates in calculating
    and allocating fees and expenses. But the court may not award defendants an aggregation
    of all fees they expended in the case based on a generalized finding of numerous,
    unspecified discovery abuses.
    21
    Fourth, after the court determines what fees and expenses were incurred as a result
    of Cal Fire’s misconduct, the trial court must apply the principle of reasonableness to
    determine whether the fees and expenses incurred were “reasonable.” (Cornerstone,
    supra, 56 Cal.App.5th at p. 791; Argaman v. Ratan, supra, 73 Cal.App.4th at p. 1179 [an
    award of monetary sanctions may not exceed the reasonable expenses actually incurred].)
    II
    Lack of Predicate Motion to Compel
    In its decision on remand, the trial court concluded that defendants were not
    required to file a motion to compel prior to requesting monetary sanctions for Cal Fire’s
    discovery misuses. Cal Fire argues that the trial court erred by awarding monetary
    sanctions without a predicate discovery motion. Cal Fire contends that section 2023.030
    only authorizes a court to impose monetary sanctions “ ‘[t]o the extent authorized by’ the
    specific provision of the Discovery Act that governs the discovery method at issue.”
    According to Cal Fire, this language means that, in almost all cases, a court is authorized
    to impose monetary sanctions only against a party who unsuccessfully makes or opposes
    a discovery motion, such as a motion a to compel. Here, except for the WiFITER fund
    documents, defendants never filed a motion to compel or other discovery motion. Thus,
    Cal Fire contends any monetary sanctions award must be limited to the reasonable
    expenses incurred as a result of the WiFITER discovery abuses.
    Defendants contend that Cal Fire forfeited this argument by failing to raise it in the
    prior appeal and that law of the case prevents us from considering it here. In any event,
    defendants contend, the argument lacks merit.
    We agree that law of the case bars Cal Fire from challenging the trial court’s
    authority to impose monetary sanctions without a predicate discovery motion, but only as
    to the discovery misuses for which we concluded there was substantial evidence to
    support imposition.
    22
    Under the doctrine of law of the case, “ ‘the decision of an appellate court, stating
    a rule of law necessary to the decision of the case, conclusively establishes that rule and
    makes it determinative of the rights of the same parties in any subsequent retrial or appeal
    in the same case.’ [Citation.]” (Nally v. Grace Community Church (1988) 
    47 Cal.3d 278
    , 301-302.) As a general rule, the doctrine applies only to issues which were both
    presented and determined in the prior appeal. (Bovard v. Am. Horse Enters. (1988)
    
    201 Cal.App.3d 832
    , 841.) However, an exception to the doctrine has been recognized
    where the prior appellate judgment could not have been rendered without implicitly
    deciding the issue, even though it was not expressly mentioned in the decision. (Sargon
    Enterprises, Inc. v. University of Southern California (2013) 
    215 Cal.App.4th 1495
    ,
    1505; accord, City of Oakland v. Superior Court (1983) 
    150 Cal.App.3d 267
    , 278.)
    In our prior opinion, we confronted the issue whether there was substantial
    evidence to support a finding that Cal Fire engaged in a misuse of the discovery process.
    (Howell, supra, 18 Cal.App.5th at pp. 192-193.) We concluded that there was substantial
    evidence to support a finding of discovery misuse as to five of the seven examples
    identified by the trial court. (Ibid.) Although the requirement of a predicate motion was
    not raised as an argument by counsel, or mentioned in our opinion, we could not have
    rendered this opinion without deciding that a predicate motion was not required as to
    those discovery misuses, and this is now law of the case.
    However, our opinion did not decide whether there was substantial evidence in the
    record to support imposition of sanctions based on any other alleged misuses of the
    discovery process. (Howell, supra, 18 Cal.App.5th at pp. 192-193, 195; see also id. at
    p. 198.) It was unnecessary to our decision. Thus, our prior decision did not foreclose
    Cal Fire from challenging on remand the trial court’s authority to impose monetary
    sanctions for other alleged discovery violations.
    Turning to the merits, we agree with Cal Fire that, under the discovery statutes, a
    party subject to misuse of the discovery process usually must seek sanctions as part of a
    23
    motion to compel. “ ‘It is a central precept to the Civil Discovery Act . . . that civil
    discovery be essentially self-executing. [Citation.]’ [Citation.]” (Clement v.
    Alegre (2009) 
    177 Cal.App.4th 1277
    , 1291; accord, Zellerino v. Brown (1991)
    
    235 Cal.App.3d 1097
    , 1111.) “Conduct frustrates the goal of a self-executing discovery
    system when it requires the trial court to become involved in discovery because a dispute
    leads a party to move for an order compelling a response.” (Clement v. Alegre, supra, at
    pp. 1291-1292.) To further this purpose, the discovery statutes ordinarily require that a
    motion for sanctions be connected to a motion to correct or cure the perceived discovery
    defect. (See, e.g., §§ 2031.320, subd. (b), 2023.030, subd. (a).) For this reason, the
    amount of sanctions imposed typically is based on the fees and expenses incurred in
    compelling compliance with a specific discovery request. (Argaman v. Ratan, supra,
    73 Cal.App.4th at p. 1179.)
    However, in a proper case, a court may entertain a motion for sanctions without a
    corresponding motion to compel, such as where a motion to comply would have been
    futile, where the evidence was intentionally destroyed, where the answer given was
    willfully false, where the misconduct was not discovered until after the time for bringing
    a motion to compel had expired, or other extraordinary circumstances. (Sherman, supra,
    67 Cal.App.4th at pp. 1162-1164; New Albertsons, Inc. v. Superior Court, 
    supra,
    168 Cal.App.4th at p. 1426; Vallbona v. Springer (1996) 
    43 Cal.App.4th 1525
    , 1546; Do
    It Urself Moving & Storage, Inc. v. Brown, Leifer, Slatkin & Berns (1992) 
    7 Cal.App.4th 27
    , 36, superseded by statute on other grounds as stated in Brantley v. Pisaro (1996)
    
    42 Cal.App.4th 1591
    , 1595; Saxena v. Goffney, supra, 159 Cal.App.4th at p. 334; see also
    Pate v. Channel Lumber Co. (1997) 
    51 Cal.App.4th 1447
    , 1456.)
    On this record, we are unable to ascertain whether defendants were required to file
    a predicate motion to compel for the other alleged discovery abuses, both because we do
    not know the nature of the specific discovery violation, and because we do not know how
    and when defendants discovered the violation. Because we are remanding the case for
    24
    other reasons, we shall direct the trial court to determine, with findings, whether a
    predicate motion to compel was required for each discovery misuse upon which the
    award is based (except those misuses previously identified and found to be supported by
    substantial evidence in Howell).
    III
    Costs Award
    Cal Fire also challenges the trial court’s statutory costs award. Cal Fire argues: (1)
    the trial court failed to apportion costs between Cal Fire and the private party plaintiffs,
    (2) the trial court improperly included $24,286.86 in costs that Sierra Pacific had agreed
    to withdraw, and (3) the trial court improperly awarded Sierra Pacific $172,564.37 in
    deposition costs related to the federal action. Defendants do not oppose reducing the
    award by the $24,286.86 in costs that Sierra Pacific agreed to withdraw, but contend the
    award should otherwise be affirmed.
    A.     Additional facts
    Prior to the first appeal, the trial court entered three separate orders awarding
    costs. (Howell, supra, 18 Cal.App.5th at p. 183.) To Beaty and Landowners, the trial
    court awarded statutory costs in the amount of $583,173.15. (Ibid.) To Sierra Pacific, it
    awarded costs in the amount of $2,852,209.34. (Ibid.) To Howell, it awarded costs in the
    amount of $417,604.06. (Ibid.) In Howell, supra, 
    18 Cal.App.5th 154
    , we concluded
    that only Sierra Pacific, Beaty, and Landowners were entitled to a statutory award of
    costs, as prevailing parties against Cal Fire. (Id. at pp. 183, 204.) Because the trial
    court’s orders awarding costs did not differentiate costs incurred by defendants in
    response to Cal Fire’s action, we remanded with directions for the trial court to determine
    an appropriate award of costs to Sierra Pacific, Beaty, and Landowners. (Ibid.)
    On remand, the trial court awarded $1,214,296.93 in costs to Sierra Pacific, and
    $299,798.47 in costs to Beaty/Landowners.

    B.     Analysis
    Under section 1032, “a prevailing party is entitled as a matter of right to recover
    costs in any action or proceeding.” (§ 1032, subd. (b).) Section 1033.5 identifies which
    costs are allowable as costs and which costs are prohibited unless otherwise authorized
    by law. (§ 1033.5, subd. (a).) Under section 1033.5, subdivision (c)(4), costs that are
    neither permitted nor prohibited “may be allowed or denied in the court’s discretion.”
    (§ 1033.5, subd. (c)(4).) Any costs awarded must be “incurred,” “reasonably necessary to
    the conduct of the litigation,” and “reasonable in amount.” (§ 1033.5, subd. (c)(1), (2) &
    (3).) We review a trial court’s award of costs for abuse of discretion. (Friends of Lagoon
    Valley v. City of Vacaville (2007) 
    154 Cal.App.4th 807
    , 834.)
    We conclude that Cal Fire has failed to meet its burden to show the trial court
    abused its discretion. Cal Fire’s argument that defendants failed to apportion costs
    amounts to a single sentence in its opening brief, citing to two pages from Cal Fire’s
    opposition brief below. This minimal showing, unsupported by adequate citations to the
    record, is insufficient to show an abuse of discretion. (Winograd v. American
    Broadcasting Co. (1998) 
    68 Cal.App.4th 624
    , 631 [the trial court’s ruling is presumed
    correct and the burden of demonstrating error rests on the appellant]; Alki Partners, LP v.
    DB Fund Services, LLC (2016) 
    4 Cal.App.5th 574
    , 590 [matters set forth in points and
    authorities are not evidence].)
    Similarly, other than arguing that the $172,564.37 in deposition costs relate to the
    federal action, Cal Fire has failed to explain why the depositions were not reasonably
    necessary to the conduct of the litigation or why the amount claimed was unreasonable.
    Defendants, in contrast, explained to the trial court that the depositions were necessary
    because several key witnesses were federal employees and the United States government
    refused to allow its employees to be deposed in the state action.
    26
    We accept the concession regarding the $24,286.86 in costs that Sierra Pacific
    agreed to withdraw, but Cal Fire has otherwise failed to meet its burden to show an abuse
    of discretion. Accordingly, we shall modify the costs award to reduce the amount
    awarded to Sierra Pacific by $24,286.86, and affirm the costs award as modified.
    DISPOSITION
    The postjudgment order imposing monetary discovery sanctions against Cal Fire is
    affirmed as to the costs award, but the part of the order pertaining to the monetary
    sanctions award is reversed and remanded for the trial court to determine the reasonable
    expenses incurred by defendants as a result of Cal Fire’s misuses of the discovery
    process, in a manner consistent with this opinion. The parties shall bear their own costs
    on appeal. (Cal. Rules of Court, rule 8.278.)
