    Opinion of the Court
    OPINION
    Judge Jennifer B. Campbell delivered the opinion of the Court, in which
    Presiding Judge D. Steven Williams and Judge James B. Morse Jr. joined.
    C A M P B E L L, Judge:
    ¶1             Dr. Seyed Mohsen Sharifi Takieh (“Sharifi”) appeals the
    superior court’s entry of summary judgment in favor of Dr. James Del
    Giorno and Janice Dinner on his defamation claims. He also challenges two
    of the court’s discovery rulings and its award of attorneys’ fees against him.
    We conclude the court properly entered summary judgment and, because
    statements derived from a peer-review process are privileged, the superior
    court properly precluded Sharifi’s discovery requests under A.R.S. § 36-
    445.01. We also affirm the court’s attorneys’ fees award.
    BACKGROUND
    ¶2           For more than a decade, Sharifi, a cardiologist, maintained
    active medical staff membership and clinical privileges at Banner Baywood
    Medical Center (“Baywood”) in Mesa. His good standing and affiliation
    with Baywood ended, however, when Baywood’s Medical Executive
    Committee (“MEC”), a peer-review body, voted to restrict his practice and
    the Banner Health Board of Directors voted to revoke his clinical privileges.
    ¶3             Amidst these adverse actions, Sharifi filed a complaint
    alleging various claims against several individuals involved in the peer-
    review process. The defendants moved to dismiss the complaint, primarily
    arguing they were immune from liability for any claims arising out of peer-
    review proceedings. See A.R.S. § 36-445.02 (A), (B) (immunizing from
    “liability for civil damages or legal action” any participant in a medical
    peer-review proceeding who “makes a decision or recommendation” or
    “furnishes any records, information, or assistance” to “medical staff or
    review committee or related organization”).
    ¶4           The superior court granted the motions to dismiss “in large
    part,” reasoning that the defendants were immune from liability under
    A.R.S. § 36-445.02 for actions taken and statements made during peer-
    2
    TAKIEH M.D. v. O’MEARA M.D., et al.
    Opinion of the Court
    review proceedings.1 With respect to the remaining claims, the court
    allowed Sharifi to file an amended complaint. In the amended complaint,
    Sharifi alleged claims against Del Giorno and Dinner for defamation,
    injurious falsehood, intentional interference with contract, and conspiracy.
    Sharifi premised each claim on the same two assertions: (1) Del Giorno,
    Baywood’s chair of cardiology, made damaging false statements when he
    told another cardiologist that Sharifi “is an idiot” who administered blood
    thinner “to an obvious case of intracerebral hemorrhage,” and (2) Dinner,
    Banner Health’s senior associate general counsel, composed “letters and
    various other documents and communications” containing “defamatory
    material . . . designed to destroy his reputation in the medical community.”
    ¶5            In their answers, neither defendant denied making the
    alleged statements. Del Giorno, however, asserted that to the extent he
    made any assertions of fact, they were true, and that otherwise, his
    statements were merely opinion, and therefore not actionable. Dinner, in
    turn, maintained that she was immune from liability because her actions
    “were done as part of and within” protected peer-review proceedings. See
    A.R.S. § 36-445.02 (A), (B).
    ¶6             As the litigation progressed, Sharifi moved to compel Dinner
    to disclose, among other things: (1) Baywood’s investigation of sexual-
    harassment allegations made against him, (2) his personnel/credentialing
    file, and (3) correspondence Dinner sent or received concerning him. After
    oral argument, the court ruled that documents in Sharifi’s file pertaining to
    his credentials and the sexual-harassment allegations were protected from
    disclosure by the peer-review privilege and Dinner was not required to
    create a privilege log listing them. With respect to the request for any
    documents/communications Dinner authored or received concerning
    Sharifi, the court ordered Dinner to produce the documents or a privilege
    log identifying “any that are claimed to be privileged.”
    ¶7            After the close of discovery, Dinner and Del Giorno moved
    for summary judgment. In response, Sharifi moved for the appointment of
    a special discovery master to review the documents Dinner had withheld,
    asserting that Dinner had failed to comply with the disclosure order. As
    detailed by Sharifi, Dinner withheld all the documents he had sought and
    had failed to produce a log, saying only that she had reviewed her emails
    and determined that all the requested correspondence constituted
    protected peer-review materials. Attached to his motion, Sharifi disclosed,
    1        On appeal, Sharifi does not challenge the superior court’s dismissal
    order.
    3
    TAKIEH M.D. v. O’MEARA M.D., et al.
    Opinion of the Court
    for the first time, the affidavits of two former Baywood employees: Leslie
    Wilson, a cardiac sonographer, and Dr. Ava Rose, an internist. Wilson
    avowed that she witnessed Dinner speaking on a cell phone and overheard
    her make several disparaging remarks about Sharifi, including that he is a
    terrible doctor, a danger to his patients, and an idiot. Rose, in turn, avowed
    that she overheard three physicians discussing their testimony against
    Sharifi in the peer-review proceedings and recounted that they said Dinner
    had encouraged them to make false statements and assured them that they
    would have immunity for their participation. In response, Dinner moved to
    strike both affidavits as untimely.
    ¶8             The superior court denied Sharifi’s motion for appointment
    of a special discovery master, finding no evidence to suggest that any of the
    correspondence at issue “originated outside the peer review process.” The
    court also struck the Rose and Wilson affidavits as untimely.
    ¶9            After full briefing, the superior court entered summary
    judgment in favor of Del Giorno and Dinner. The court explained that even
    assuming Del Giorno made the alleged statements to his fellow
    cardiologist, there was no dispute that Sharifi had, in fact, administered
    blood thinner to a patient who had an intracerebral hemorrhage. Further,
    concluding that the “characteriz[ation]” of Sharifi’s conduct “as idiotic”
    was “nothing more” than a “subjective impression,” the court found Del
    Giorno’s alleged “assessment” was not an actionable statement of fact.
    Turning to the allegations against Dinner, the court found that Sharifi had
    failed to produce any admissible evidence showing that Dinner “made any
    comments about him, defamatory or otherwise, outside the context of
    [protected] peer review activities.”
    ¶10           Having prevailed on summary judgment, Dinner requested
    an award of attorneys’ fees under A.R.S. § 12-349, asserting that Sharifi
    brought the defamation claim against her without substantial justification
    and primarily for harassment. The court agreed and awarded Dinner
    $128,878.00 in attorneys’ fees and $1,444.92 in taxable costs, finding no
    evidence to suggest that when Sharifi filed his amended complaint, he “had
    a good faith belief” that Dinner had made any defamatory statements about
    him that were not protected by the peer-review privilege. The court
    reduced its rulings to a final judgment, and Sharifi timely appealed.

    Opinion of the Court
    DISCUSSION
    I.     Summary Judgment Rulings
    ¶11            “The court shall grant summary judgment if the moving party
    shows that there is no genuine dispute as to any material fact and the
    moving party is entitled to judgment as a matter of law.” Ariz. R. Civ. P.
    56(a). In reviewing a grant of summary judgment, we view the facts and the
    reasonable inferences to be drawn from those facts in the light most
    favorable to the non-moving party and will affirm “if the evidence
    produced in support of the defense or claim has so little probative value
    that no reasonable person could find for its proponent.” State Comp. Fund v.
    Yellow Cab Co. of Phoenix, 
    197 Ariz. 120
    , 122, ¶ 5 (App. 1999). “We review de
    novo the [superior] court’s application of the law and its determination
    whether genuine issues of material fact preclude summary judgment.” 
    Id.
    A.     Defamation Claim Against Del Giorno
    ¶12          Sharifi argues the court erred in dismissing his defamation
    claim against Del Giorno because Del Giorno’s statements about him
    conveyed assertions of fact that were both false and damaging.
    ¶13             The right to free speech, enshrined in the First Amendment,
    is not absolute ―“[s]ociety has a pervasive and strong interest in preventing
    and redressing” defamatory speech. Milkovich v. Lorain Journal Co., 
    497 U.S. 1
    , 22 (1990) (citation and internal quotation omitted). Nonetheless, because
    “the expense of defending a meritless defamation case” can have “a chilling
    effect on First Amendment rights,” Read v. Phoenix Newspapers, Inc., 
    169 Ariz. 353
    , 357 (1991), “the superior court must act as gatekeeper protecting
    the right to free speech” from encroachment. Sign Here Petitions LLC v.
    Chavez, 
    243 Ariz. 99
    , 102, ¶ 1 (App. 2017); see also Yetman v. English, 
    168 Ariz. 71
    , 79 (1991) (“Given the rigorous scrutiny required by the first
    amendment,” the court must “carefully examine every alleged defamatory
    statement . . . to ensure that first amendment concerns are protected.”).
    ¶14           To support a claim for defamation, a statement about a
    private figure on a matter of private concern “must be false” and must bring
    the subject of the statement “into disrepute, contempt, or ridicule” or
    impeach the subject’s “honesty, integrity, virtue, or reputation.” Turner v.
    Devlin, 
    174 Ariz. 201
    , 203–04 (1993) (quoting Godbehere v. Phoenix
    Newspapers, Inc., 
    162 Ariz. 335
    , 341 (1989)). While any disparaging statement
    can cause reputational harm, a true statement cannot support a claim for
    defamation. Read,

    TAKIEH M.D. v. O’MEARA M.D., et al.
    Opinion of the Court
    ¶15            In fulfilling its gatekeeping role, the superior court first must
    determine “whether, under all the circumstances, a statement is capable of
    bearing a defamatory meaning.” Yetman, 
    168 Ariz. at 79
     (citing Restatement
    (Second) of Torts § 614 (1977)). As a matter of law, a statement is not
    actionable if it is comprised of “loose, figurative, or hyperbolic language”
    that cannot reasonably be interpreted as stating or implying facts
    “susceptible of being proved true or false.” Milkovich, 
    497 U.S. at 21
    . In a
    case such as this, “[t]he key inquiry is whether the challenged expression,
    however labeled by defendant, would reasonably appear to state or imply
    assertions of objective fact.” Yetman, 
    168 Ariz. at 76
     (citation and internal
    quotation omitted). In this determination, the court should “‘consider the
    impression created by the words used as well as the general tenor of the expression,
    from the point of view of a reasonable person’ at the time the statement was
    uttered and under the circumstances it was made.” Sign Here Petitions, 243
    Ariz. at 105, ¶ 21 (quoting Yetman, 
    168 Ariz. at 76
    ).
    ¶16           While statements cast as subjective beliefs are generally
    insulated from defamation liability, “statements of opinion are actionable
    when they imply a false assertion of fact.” Turner, 
    174 Ariz. at 208
     (internal
    quotation omitted and emphasis added). In other words, if a statement of
    opinion may be proven false, “it is actionable as defamatory,” Dube v. Likins,
    
    216 Ariz. 406
    , 419, ¶ 46 (App. 2007), but a statement is not actionable if it
    does not present “the kind of empirical question a fact-finder can resolve,”
    Yetman, 
    168 Ariz. at 81
    . Finally, “[t]o defeat a defendant’s motion for
    summary judgment in a defamation case, the plaintiff must present
    evidence ‘sufficient to establish a prima facie case with convincing clarity.’”
    Sign Here Petitions, 243 Ariz. at 104, ¶ 14 (citation omitted).
    ¶17            With these principles in mind, we consider Del Giorno’s
    alleged statements. To prove his defamation claim against Del Giorno,
    Sharifi relied primarily on the declaration of Dr. Suzanne Sorof, a
    cardiologist. As detailed in her brief statement, Sorof saw and heard Del
    Giorno talking to another cardiologist through a partially open door. She
    recounted that Del Giorno stated: “Sharifi is an idiot. We finished his
    venous career here and won’t let it continue anywhere at Banner. He gave
    tPA to an obvious case of intracerebral hemorrhage.” From Del Giorno’s
    tone and demeanor, Sorof concluded that he was “angry.”
    ¶18           Addressing the alleged falsity of Del Giorno’s statements,
    Sharifi neither denied that he administered blood thinner to the patient nor
    that she had an intracerebral hemorrhage. He argued instead that he was
    not an “idiot” and that the patient’s hemorrhage was not obvious at the
    time. In support, he asserted that he had an expert who would testify that
    6
    TAKIEH M.D. v. O’MEARA M.D., et al.
    Opinion of the Court
    a CT scan of the patient “complete[ly] negated” the “possibility” of a
    hemorrhage and that “no physician could interpret [the patient’s] chart – at
    the time [] Sharifi administered tPA – in such a manner as to indicate that
    [the patient’s] condition was ‘obvious.’”
    ¶19            Viewed in context, Del Giorno’s “angry” statement to a fellow
    physician that Sharifi is “an idiot” clearly did not suggest that Sharifi, a
    board-certified specialist in cardiovascular medicine, suffers from an
    extreme intellectual disability, as the term “idiot” was historically used in
    both medical and educational settings. See Idiot, Merriam-Webster,
    https://www.merriam-webster.com/dictionary/idiot (last visited August
    4, 2021). Instead, consistent with the modern understanding of the word
    and common usage, Del Giorno was expressing his belief that Sharifi acted
    foolishly. See id. (defining “idiot” as “a foolish or stupid person”). Because
    assessments like these of foolishness or stupidity are subjective
    determinations, there is no means to establish their truth or falsity. In other
    words, a statement that someone is an idiot is inherently a statement of
    opinion, not objective fact. See Steinhausen v. HomeServices of Nebraska, Inc.,
    
    857 N.W.2d 816
    , 828 (Neb. 2015) (concluding that the term “idiot” is a
    “subjective impression[]” that “cannot be defamatory”). Therefore, we
    agree with the superior court that Del Giorno’s “idiot” statement is not
    actionable as a matter of law because it does not present “the kind of
    empirical question a fact-finder can resolve.” Yetman, 
    168 Ariz. at 81
    .
    ¶20             Turning to Del Giorno’s description of the patient’s
    hemorrhage as “obvious,” we apply a similar analysis. Whether something
    is easily perceived or understood is a matter of opinion.
    See        Obvious,         Merriam-Webster,         https://www.merriam-
    webster.com/dictionary/obvious (last visited August, 2021) (defining
    “obvious” as “easily discovered, seen, or understood”). Had Del Giorno
    told his colleague that the patient’s hemorrhage was diagnosed,
    documented, or otherwise confirmed, he would have been stating a matter
    of objective fact, provable as true or false. Instead, he expressed his belief
    that the hemorrhage should have been readily apparent. To refute Del
    Giorno’s assertion, Sharifi asserted his expert would testify that a
    reasonable doctor would not have detected the patient’s hemorrhage before
    administering a blood-thinner medication. The nature of the opinion
    evidence Sharifi asserted he could offer to prove defamation belies one of the
    tort’s requisite elements—the utterance of a statement of fact. Moreover, as
    Del Giorno points out, the overall impression of his words, including his
    alleged angry tone and use of the term “idiot,” would not lead a reasonable
    listener to believe that he was making a statement of verifiable, medical fact.
    Because the record on summary judgment lacked clear and convincing
    7
    TAKIEH M.D. v. O’MEARA M.D., et al.
    Opinion of the Court
    evidence that a reasonable listener could have understood Del Giorno’s
    “obvious” statement as conveying an objective fact, the superior court
    properly entered summary judgment dismissing Sharifi’s defamation claim
    against him.
    B.     Defamation Claim Against Dinner
    ¶21           Sharifi also challenges the dismissal of his defamation claim
    against Dinner, contending that he failed to carry his burden to establish a
    prima facie case only because the superior court erroneously (1) relieved
    Dinner of her obligation to disclose email communications concerning him,
    and (2) struck the Wilson and Rose declarations.
    1.     Disclosure Ruling Regarding Emails
    ¶22           After the superior court made its initial disclosure order,
    Dinner responded that she had reviewed her email correspondence and
    found 738 emails concerning Sharifi. Although Dinner determined most of
    the emails were privileged attorney-client communications, she did not
    create a privilege log because she concluded all the emails were prepared
    in connection with peer-review proceedings that she contended were
    protected from discovery by A.R.S. § 36-445.01(A). Finding no evidence to
    “suggest that any of the 738 documents at issue originated outside the peer
    review process,” the court denied Sharifi’s request for the appointment of a
    special discovery master to review each of the emails in camera.
    ¶23           On appeal, Sharifi asserts that the superior court’s approach
    “allow[ed] Dinner to unilaterally determine that the peer review protection
    applied to large categories of unidentified documents (including her own
    personal emails).” In other words, without a privilege log or in camera
    review of the documents, Sharifi argues he had no “means to challenge”
    Dinner’s contention that the emails were, in fact, prepared or received in
    connection with peer-review proceedings.
    ¶24           Although superior courts have broad discretion in resolving
    discovery disputes, Am. Family Mut. Ins. v. Grant, 
    222 Ariz. 507
    , 511, ¶ 11
    (App. 2009), whether a disclosure obligation exists or a privilege applies is
    a question of law that we review de novo. Solimeno v. Yonan, 
    224 Ariz. 74
    ,
    77, ¶ 9 (App. 2010); Ledvina v. Cerasani, 
    213 Ariz. 569
    , 571, ¶ 3 (App. 2006).
    Under Arizona Rule of Civil Procedure 26(b)(1), “[p]arties may obtain
    discovery regarding any nonprivileged matter that is relevant to any
    party’s claim or defense and proportional to the needs of the case.”
    8
    TAKIEH M.D. v. O’MEARA M.D., et al.
    Opinion of the Court
    ¶25           State law requires peer review of physicians in Arizona
    hospitals. To “reduc[e] morbidity and mortality” and improve “the care of
    patients,” each Arizona hospital or surgical center “shall require that
    physicians admitted to practice in the hospital or center organize into
    committees . . . to review the professional practices within the hospital or
    center,” including “the preventability of complications and deaths.” A.R.S.
    § 36-445. By statute, the participants in these mandated peer-review
    committees are immune from liability “to any person who is denied the
    privilege to practice in a hospital or center or whose privileges are
    suspended, limited or revoked.” A.R.S. § 36-445.02(B). As further
    protection, “[a]ll . . . materials prepared in connection with” peer-review
    proceedings are privileged and confidential and therefore “not subject to
    discovery.” A.R.S. § 36-445.01(A).
    ¶26           “Arizona courts have recognized that the confidentiality of
    peer review committee proceedings is essential to achieve complete
    investigation and review of medical care.” Humana Hosp. Desert Valley v.
    Superior Ct., 
    154 Ariz. 396
    , 400 (App. 1987). Because peer-review
    deliberations would be substantially compromised “if they were subject to
    the discovery process,” the peer-review privilege must remain inviolate. Id.;
    Goodman v. Samaritan Health Sys., 
    195 Ariz. 502
    , 509, ¶ 27 (App. 1999) (“If
    effective peer review is to be achieved, and the statutory goal [of reducing
    morbidity and mortality and improving patient care] realized, peer
    reviewers and their hospitals must have some protection against money
    damage claims.”).
    ¶27           While materials created outside the peer-review process that
    “do not contain references” to peer-review proceedings are discoverable,
    “the internal workings and deliberative process” of peer-review
    committees are “immune from discovery.” Humana, 
    154 Ariz. at 403
    .
    Accordingly, “a plaintiff is not entitled to engage in a fishing expedition to
    ascertain what information was considered by the peer review committee
    where such information might reveal the deliberative process of the
    participants.” Yuma Reg’l Med. Ctr. v. Superior Ct., 
    175 Ariz. 72
    , 77 (App.
    1993).
    ¶28           We find Yuma Regional particularly instructive here. In that
    case, the plaintiffs sought information concerning the hospital’s peer-
    review proceedings, including lists identifying each participant and each
    document submitted. 
    Id. at 74
    . After the superior court ordered the hospital
    to furnish the plaintiffs with a redacted copy of the requested information
    and “to provide the court with a redacted copy and an original of the same”
    for in camera review, the hospital petitioned this court for relief. 
    Id. at 74, 9
    TAKIEH M.D. v. O’MEARA M.D., et al.
    Opinion of the Court
    77. On special action review, we concluded the court’s order that the
    hospital disclose the names of the peer-review participants “violate[d] the
    peer review privilege.” 
    Id. at 75
    –76. We further found that “requiring
    submission” of the requested information to the court, “in any form,” also
    violated the privilege. 
    Id. at 77
    .
    ¶29            Sharifi argues that, at a minimum, Dinner should have been
    required to produce a log identifying the sender and recipient of each email
    or other document she withheld on peer-review grounds. As Banner’s
    general counsel, Dinner provided legal advice concerning the peer-review
    proceedings to both potential witnesses and the MEC members. To
    illustrate this point, the Rose declaration that Sharifi offered, though
    ultimately stricken, reflects that multiple physicians spoke with Dinner and
    received her legal advice regarding any potential liability for participating
    as witnesses in the peer-review proceedings. Because the “element of
    confidentiality is essential” to ensure a candid peer review, Humana, 
    154 Ariz. at 401,
     and given the overriding public interest in peer-review
    proceedings, we conclude that the superior court did not err by finding the
    peer-review privilege exempted Dinner from having to submit a log that
    would identify with whom she exchanged correspondence related to the
    peer-review process.2 Sun Health Corp. v. Myers, 
    205 Ariz. 315
    , 319, ¶ 13
    (App. 2003) (“[T]he identity of the participants in a peer review proceeding
    is not discoverable.”).
    ¶30          Sharifi further contends that the superior court erred by
    denying his request to appoint a special discovery master to review the
    documents Dinner withheld to confirm that, as she asserted, each of the
    communications was made in connection with peer-review proceedings. As
    noted, in Yuma Regional, this court vacated a ruling mandating in camera
    review by the superior court of documents purportedly privileged by peer
    2      Sharifi also contends that Dinner waived the peer-review privilege
    with respect to all peer-review documents by submitting five documents
    related to the peer-review process in support of her motion for summary
    judgment. We review de novo whether a party has waived a privilege. See
    Twin City Fire Ins. Co. v. Burke, 
    204 Ariz. 251
    , 253–54, ¶ 10 (2003). The
    documents at issue are three letters addressed to Sharifi from a Baywood
    medical officer and two letters from Sharifi’s attorney to Dinner. While
    these documents were unquestionably prepared in connection with the
    peer-review process, they were already in Sharifi’s possession, and his
    contention that their “disclosure” waived the peer-review privilege in its
    entirety is wholly without merit.

    Opinion of the Court
    review. Sharifi offers no argument why that principle would not likewise
    bar in camera review by a discovery master. Without good cause for
    appointment of a special master, the court did not abuse its discretion by
    denying Sharifi’s request. See Ariz. R. Civ. P. 53(a)(1).3
    2.     Disclosure Ruling Regarding the Wilson and Rose
    Declarations
    ¶31           Unable to rely on any documents protected by the peer-
    review process, Sharifi’s claim against Dinner was based solely on
    assertions recounted in the declarations of Wilson and Rose, which he
    offered in response to Dinner’s motion for summary judgment. The
    superior court struck both declarations as untimely, and Sharifi argues on
    appeal it erred in doing so.
    ¶32            The superior court’s scheduling order required the parties to
    disclose their non-expert witnesses by March 1, 2019 and provide any
    supplemental disclosure by June 28, 2019. In his initial disclosure statement,
    Sharifi identified Wilson as a person possessing information relevant to the
    case. Specifically, Sharifi disclosed that Wilson, a “former echo lab
    technician” at Baywood, “overheard disparaging remarks.” This brief and
    vague description neither identified the individual who made the
    comments Wilson purportedly overheard nor revealed the substance of the
    statements, as the rules require. See Ariz. R. Civ. P. 26.1(a)(3) & (4).
    ¶33         As the litigation progressed, Sharifi failed to provide any
    supplemental disclosure regarding Wilson, or any disclosure regarding
    3      Although Sharifi makes a fleeting reference to unspecified
    documents purportedly located in his credentialing file, asserting they are
    not necessarily privileged, he fails to develop that argument and does not
    address whether his credentialing file was used in a peer-
    review/credentialing process, as the superior court found. See Humana, 
    154 Ariz. at 402
     (“[B]ecause the statutes expressly refer to the confidentiality of
    peer review of applications for staff privileges and because of the public
    interest in such confidentiality, we hold that the peer review privilege
    protects the credentialing process.”). Having failed to present a reviewable
    argument, Sharifi has waived any issue regarding the disclosure of his
    credentialing file. See ARCAP 13(a)(7).

    TAKIEH M.D. v. O’MEARA M.D., et al.
    Opinion of the Court
    Rose,4 until he filed his request for the appointment of a special discovery
    master, approximately two months after the disclosure deadline. In
    reviewing Dinner’s motion to strike the Wilson and Rose declarations, the
    superior court found the declarations went “well beyond any previous
    disclosure[s],” and in the absence of a showing of good cause, the court
    struck them as untimely.
    ¶34            Rule 26.1(a)(3) requires a party to identify each witness it may
    use at trial. The party also must provide “a description of the substance—
    and not merely the subject matter—of the testimony sufficient to fairly
    inform the other parties of each witness’ expected testimony.” Ariz. R. Civ.
    P. 26.1(a)(3). When a party has failed to timely disclose the required
    information, it “may not use the information, witness, or document as
    evidence at trial” unless “the court specifically finds that such failure
    caused no prejudice or orders otherwise for good cause.” Ariz. R. Civ. P.
    37(c)(1). Because the superior court is in a better position to determine
    whether “a disclosure violation has occurred in the context of a given case”
    and, if so, its “practical effect,” we uphold its disclosure rulings absent a
    clear abuse of discretion. Solimeno, 224 Ariz. at 77, ¶ 9.
    ¶35           As detailed in his complaint, Sharifi broadly alleged that
    Dinner sent or received communications that included defamatory
    statements about him. Although Sharifi had disclosed that Wilson had
    some information about alleged defamatory statements, he failed to
    disclose the substance of the statements or who made them. Given the
    framing of Sharifi’s defamation claim against Dinner, his disclosures failed
    to provide her with notice that any witness directly overheard her making
    defamatory statements or what those statements were. Moreover, Sharifi
    did not seek leave of the court to use the untimely disclosed declarations by
    submitting an affidavit demonstrating that he disclosed the information “as
    soon as practicable after its discovery.” See Ariz. R. Civ. P. 37(c)(4)(B). On
    this record, the superior court did not abuse its discretion by finding the
    Wilson and Rose declarations untimely and striking them from the record.
    Accordingly, because Sharifi failed to present any admissible evidence to
    substantiate his allegations against Dinner, much less any clear and
    convincing evidence, the superior court properly entered summary
    judgment in favor of Dinner on his defamation claim.
    4      Sharifi contends he timely disclosed Rose as a witness but referred
    to her as Dr. Rosenblum in prior disclosures. The record reflects that Sharifi
    timely disclosed a 2018 affidavit from a Dr. Rosenblum, but that affidavit
    did not contain any of the allegations made in the Rose affidavit.

    TAKIEH M.D. v. O’MEARA M.D., et al.
    Opinion of the Court
    II.    Award of Attorneys’ Fees
    ¶36           Finally, Sharifi challenges the superior court’s award of
    attorneys’ fees to Dinner under A.R.S. § 12-349, arguing his defamation
    claim against her was neither groundless nor brought in bad faith.
    ¶37           Under A.R.S. § 12-349(A), the court “shall” assess reasonable
    attorneys’ fees against an attorney or party who, among other things, brings
    a claim without substantial justification. As defined within the statute, a
    claim lacks substantial justification when it is both “groundless” and “not
    made in good faith.” A.R.S. § 12-349(F). While groundlessness is
    determined objectively, bad faith is a subjective determination. Rogone v.
    Correia, 
    236 Ariz. 43
    , 50, ¶ 22 (App. 2014). A claim is groundless “if the
    proponent can present no rational argument based upon the evidence or
    law in support of that claim.” 
    Id.
     (citation and internal quotation omitted).
    ¶38           In awarding attorneys’ fees under A.R.S. § 12-349, the
    superior court must “set forth the specific reasons for the award.” A.R.S.
    § 12-350. Because the “purpose of this requirement is to assist the appellate
    court on review[,] . . . the findings need only be specific enough to allow an
    appellate court to test the validity of the judgment.” Bennett v. Baxter Group,
    
    223 Ariz. 414
    , 421, ¶ 28 (App. 2010) (internal quotations and citations
    omitted).
    ¶39          We review a superior court’s application of A.R.S. § 12-349 de
    novo, but we view “the evidence in a manner most favorable to sustaining
    the award” and will affirm unless the superior court’s findings are “clearly
    erroneous.”5 Phoenix Newspapers, Inc. v. Dep’t of Corr., 
    188 Ariz. 237
    , 243, 244
    (App. 1997). We may affirm the superior court’s ruling “if it is correct for
    any reason apparent in the record.” Forszt v. Rodriguez, 
    212 Ariz. 263
    , 265,
    ¶ 9 (App. 2006).
    5      Without citing any authority, Sharifi argues that we should review
    the superior court’s findings de novo because he requested an evidentiary
    hearing and “was denied the opportunity to make a factual record.” This
    contention mischaracterizes the record and is without merit. At oral
    argument on Dinner’s request for attorneys’ fees, the superior court
    expressly invited Sharifi to supplement the record by presenting witness
    testimony or written declarations, and Sharifi responded by saying he
    would submit supplemental affidavits. His failure to do so does not,
    somehow, mean he was denied the opportunity to make a factual record.
    13
    TAKIEH M.D. v. O’MEARA M.D., et al.
    Opinion of the Court
    ¶40            Sharifi first asserts that he brought his defamation claim
    against Dinner in good faith because he believed that the anti-abrogation
    provision in the Arizona Constitution bars peer-review participants from
    invoking statutory immunity under A.R.S. § 36-445.02 when sued for
    defamation. See Ariz. Const. art. XVIII, § 6 (“The right of action to recover
    damages for injuries shall never be abrogated.”). While Sharifi correctly
    notes that prior cases upholding A.R.S. § 36-445.02 against anti-abrogation
    challenges did not consider the statute’s application in defamation actions,
    Goodman, 195 Ariz. at 509, ¶ 29 n.9 (limiting the analysis upholding A.R.S.
    § 36-445.02 against an anti-abrogation challenge to the claims raised,
    explaining that “[a] different analysis might be required if a defamation
    claim were made against an individual peer reviewer”); see also Humana,
    
    154 Ariz. at 399
    –400, the superior court ruled early in this litigation (before
    Sharifi filed his amended complaint) that no statement made during the
    peer-review process could be used to prosecute a defamation claim.
    Nonetheless, after receiving that ruling, Sharifi filed an amended complaint
    that alleged defamation against Dinner based primarily on
    communications made during the peer-review process. The superior court
    found that, at that point, Sharifi could not have had a good faith belief that
    any statements she made during the peer-review process could support a
    defamation claim against her.
    ¶41          The superior court found that, in the end, Sharifi offered no
    admissible evidence that Dinner made defamatory statements about him,
    made no “effort to determine whether [] Dinner actually made admissible
    defamatory statements about him” before filing his amended complaint,
    and failed “to withdraw his claim” when confronted with his lack of
    evidence.
    ¶42           During oral argument on Dinner’s request for attorneys’ fees,
    the superior court ordered Sharifi to file a signed affidavit setting forth the
    evidentiary basis for his amended complaint. In response, Sharifi submitted
    a declaration avowing that before he filed his amended complaint, several
    physicians privately told him that Dinner had made defamatory statements
    against him. According to Sharifi, these witnesses refused to execute
    declarations directly attributing the defamatory statements to Dinner
    because they feared “retaliation.” Nonetheless, based on these
    conversations, Sharifi avowed he “firmly believed” both that his
    defamation claim against Dinner was “supported by the facts” and that he
    “could gather enough evidence to prove” it when he filed his amended
    complaint. To substantiate his avowals, Sharifi also submitted unsigned
    declarations attributed to three Baywood physicians. Although the
    14
    TAKIEH M.D. v. O’MEARA M.D., et al.
    Opinion of the Court
    declarants each claimed to have heard disparaging remarks about Sharifi,
    none avowed to have heard such remarks directly from Dinner.
    ¶43           Having reviewed the record in its entirety, we conclude the
    superior court’s findings are not clearly erroneous. Nothing in the record
    suggests that Sharifi had any admissible evidence to support his
    defamation claim against Dinner at the time he filed his amended
    complaint. Although Sharifi asserts there were “circumstantial reasons for
    believing” that Dinner had made defamatory statements against him, he
    admits that only Wilson avowed that she directly overhead such remarks.
    According to his affidavit, Sharifi relied heavily on Wilson’s account, but
    Wilson did not allegedly overhear Dinner making disparaging remarks
    until months after Sharifi filed his amended complaint, so her account could
    not serve as the factual predicate for that complaint. Moreover, consistent
    with the superior court’s findings, the record does not reflect that Sharifi
    made any attempt to depose any of the individuals he asserts witnessed
    Dinner utter defamatory statements. In asserting that “[t]he only missing
    element was someone who heard Dinner make the statements,” Sharifi fails
    to recognize that such evidence was the necessary factual predicate for his
    defamation claim. In other words, unable to offer evidence that someone
    witnessed Dinner making defamatory statements, Sharifi based his entire
    defamation claim on supposition and speculation. Therefore, on this record,
    the superior court did not err in finding Sharifi’s claim was groundless and
    he pursued it in bad faith, and awarding Dinner her attorneys’ fees under
    A.R.S. § 12-349.
    CONCLUSION
    ¶44          For the foregoing reasons, we affirm. Dinner requests an
    award of her attorneys’ fees under A.R.S. § 12-349. Because Sharifi’s
    defamation claim was groundless and pursued in bad faith, we grant
    Dinner’s request, conditioned upon compliance with ARCAP 21.
