    disability benefits to Rafael Suastegui Bernal (Claimant). We do not
    disturb the Commission’s decision.
    BACKGROUND
    ¶2      On February 17, 2009, while working as a drywall installer
    for Danny’s Drywall, Claimant “fell 14 feet from a ladder and
    scaffold.” He suffered extensive bone fractures in his face and right
    hand, as well as tears in the muscles and cartilage of his right
    shoulder. He also experienced back and neck pain. Following
    treatment, Claimant reached medical stability from his hand and
    shoulder injuries, but headaches and continued chronic pain in his
    right jaw, neck, and lower back affected his activity level and
    ability to sleep. He was eventually diagnosed with several torn and
    bulging discs in his back.
    ¶3      In April 2010, Claimant filed an application for permanent
    total disability benefits. After a hearing, the Administrative Law
    Judge (the ALJ) decided that, due to the conflicting medical
    evidence concerning Claimant’s medical and functional limitations,
    a final determination on his eligibility for permanent total disability
    benefits could not be made without an independent medical
    review. As a result, in June 2011, the ALJ appointed a medical
    panel, consisting of specialists in pain management and psychiatry.
    In the medical panel referral letter, the ALJ informed the panel that
    it was “bound by the Findings of Fact and Conclusions of Law
    contained in my Interim Order.” As the ALJ explained, “[t]he facts
    are the historical and other legal data regarding how the injury
    occurred, dates and times, places, persons involved, and other
    related information commonly thought of as the situational
    circumstances surrounding the alleged injury.” The ALJ also stated,
    If you discover additional facts which are not
    contrary to the facts in the Findings of Fact and
    Conclusions of Law contained in my Interim Order,
    and you use them in your examination and
    evaluation, it will be necessary to include them in
    20121077-CA                       2                 
    2014 UT App 277
    Danny’s Drywall v. Labor Commission
    your report and explain how the additional facts
    affected your analysis and conclusions.
    The ALJ then instructed the medical panel to answer the following
    question: “What are [Claimant’s] permanent physical restrictions
    as a result of injury from the industrial accident on 2/17/2009?” The
    ALJ further instructed the panel to “address in your answer the
    varying opinions in the medical record and relate [Claimant’s]
    functional and medical capacity restrictions regarding his ability to
    work an eight hour work day including limits on standing, sitting,
    missing work days and breaks needed within the work day.”
    ¶4       The medical panel reviewed all relevant medical records,
    considered the opinions of the parties’ experts, and conducted its
    own examination of Claimant. The medical panel thereafter issued
    a report detailing its conclusions regarding Claimant’s functional
    and medical capacity restrictions related to the industrial accident.
    The medical panel diagnosed Claimant with a number of “medical
    conditions, as a direct result of the February 17, 2009 industrial
    accident,” including traumatic brain injury and chronic pain. The
    panel determined that Claimant had a variety of restrictions related
    to lifting, sitting, and other activities. According to the panel, it was
    unlikely that Claimant could be a productive worker for more than
    four hours a day. Even then, the panel expected Claimant to
    require additional time off due to medical care and periodic
    exacerbations of his problems.
    ¶5     In response to the medical panel report, Employer hired a
    physiatrist, Dr. Jeff Chung, to review and critique the report. In
    preparing his analysis, Dr. Chung relied entirely on the panel
    report and examined neither Claimant nor the underlying medical
    records. Although Dr. Chung agreed with some of the medical
    panel’s conclusions, Dr. Chung flatly disagreed with the panel’s
    diagnoses and also opined that the panel’s report did not
    adequately state a basis for some of its conclusions.
    ¶6     Employer filed an objection to the medical panel report,
    citing Dr. Chung’s critique and arguing (1) that the panel violated
    the charging order by evaluating matters not before it, (2) that the
    20121077-CA                        3                 
    2014 UT App 277
    Danny’s Drywall v. Labor Commission
    report was not based on reasonable medical probability, and (3)
    that other substantial evidence supported a finding contrary to the
    panel’s finding. The ALJ rejected all of Employer’s arguments and
    admitted the medical panel report into the evidentiary record.
    After considering all the evidence, the ALJ adopted the medical
    panel’s opinion regarding Claimant’s functional and medical
    capacity restrictions that were caused by the industrial accident
    and ultimately determined that Claimant was eligible for
    permanent total disability benefits.
    ¶7      Employer subsequently filed a motion for review with the
    Commission, raising the same arguments as in its objection to the
    medical panel report. Like the ALJ, the Commission rejected
    Employer’s arguments. First, the Commission concluded that “the
    medical panel did not exceed its authority, either in its personal
    examination of [Claimant], its diagnosis of his medical problems,
    or its assessment of whether those problems were caused by his
    work accident.” Second, the Commission determined that, when
    viewed as a whole, the medical panel report is based on the panel’s
    assessment of medical probability. Third, the Commission reasoned
    that the existence of contradictory evidence was not a sufficient
    reason to disregard or exclude the medical panel report. The
    Commission therefore rejected Employer’s challenges to the ALJ’s
    decision and the medical panel report on which it was based, and
    affirmed the ALJ’s decision. This petition for judicial review
    followed.
    ISSUES AND STANDARDS OF REVIEW
    ¶8      Employer first attacks the Commission’s adoption of the
    medical panel report, contending that the panel disregarded the
    charging order by evaluating medical causation, diagnosis, and
    past and future medical care. In particular, Employer argues that
    the ALJ did not refer all of those issues to the panel when the ALJ
    asked the panel to evaluate Claimant’s “permanent physical
    restrictions as a result of injury from the industrial accident.”
    Because Employer’s argument challenges the propriety of the
    Commission’s interpretation of the ALJ’s order, we review that
    20121077-CA                     4

    Contractors v. Labor Comm’n, 
    2013 UT App 230
    , ¶ 7, 
    311 P.3d 528
    .
    ¶9      Employer raises two other arguments in challenging the
    Commission’s award of permanent total disability benefits to
    Claimant, focusing on the Commission’s adoption of the medical
    panel report. “Whether the commission correctly or incorrectly
    denied benefits is a traditional mixed question of law and fact.” Jex
    v. Labor Comm’n, 
    2013 UT 40
    , ¶ 15, 
    306 P.3d 799
     (citation and
    internal quotation marks omitted); see also Murray v. Labor Comm’n,
    
    2013 UT 38
    , ¶ 33, 
    308 P.3d 461
     (“[A] mixed question arises when an
    agency . . . must apply a legal standard to a set of facts unique to a
    particular case.” (citation and internal quotation marks omitted)).
    “The standard of review we apply when reviewing a mixed
    question can be either deferential or nondeferential . . . .” Murray,
    
    2013 UT 38
    , ¶ 36. “Deference on a mixed question is warranted
    when ‘the mixed finding is not “law-like” because it does not lend
    itself to consistent resolution by a uniform body of appellate
    precedent’ or ‘is “fact-like” because the [factfinder] is in a superior
    position to decide it.’” Jex, 
    2013 UT 40
    , ¶ 15 (alteration in original)
    (emphasis omitted) (quoting Murray, 
    2013 UT 38
    , ¶ 37).
    ¶10 Next, Employer argues that the ALJ’s Interim Order was not
    sufficiently detailed and that the ALJ’s failure to provide adequate
    findings of fact led the medical panel to evaluate matters beyond
    the scope of its authority. “Whether an administrative agency’s
    findings are adequate is a legal determination that requires no
    deference.” Blair v. Labor Comm’n, 
    2011 UT App 248
    , ¶ 14, 
    262 P.3d 456
    .
    ¶11 Finally, Employer argues that the Commission erred in
    adopting the medical panel report because, according to Employer,
    other substantial evidence supports findings contrary to the
    medical panel’s findings. “We will not disturb the Commission’s
    factual findings unless the party challenging the findings
    demonstrates that a finding is not supported by substantial
    evidence.” Swift Transp. v. Labor Comm’n, 
    2014 UT App 104
    , ¶ 8,

    2013 UT 38
    , ¶ 19); see also Utah Code Ann.

    to grant relief if an “agency action is based upon a determination
    of fact . . . that is not supported by substantial evidence”). “In other
    words, the [Commission’s] factual findings are accorded
    substantial deference and will not be overturned if based on
    substantial evidence, even if another conclusion from the evidence
    is permissible.” Cook v. Labor Comm’n, 
    2013 UT App 286
    , ¶ 10,

    evidence and independently choose which inferences we find to be
    the most reasonable.” Becker v. Sunset City,

    , ¶ 21, 
    309 P.3d 223
     (citation and internal quotation marks omitted). “Instead,
    we defer to [a lower tribunal’s] findings because when reasonably
    conflicting views arise, it is the [fact-finder’s] province to draw the
    inferences and resolve these conflicts.”

    ANALYSIS
    I. Scope of the Medical Panel Report
    ¶12     Employer argues that the Commission abused its discretion
    in adopting the medical panel report because the panel disregarded
    the charging order by evaluating medical causation, diagnosis, and
    past and future medical care. Employer contends that the ALJ’s
    request that the panel evaluate Claimant’s “permanent physical
    restrictions as a result of injury from the industrial accident” did
    not authorize the panel to consider the issues of causation and
    diagnosis.
    ¶13 Section 34A-2-601 of the Utah Code permits an
    administrative law judge to refer the medical aspects of a case to a
    medical panel. Utah Code Ann. § 34A-2-601(1)(a) (LexisNexis Supp.
    2013). Pursuant to this section, an administrative law judge will
    appoint a medical panel “where one or more significant medical
    issues may be involved.” Utah Admin. Code R602-2-2(A).
    Significant medical issues are involved when there are, inter alia,
    20121077-CA                        6                
    2014 UT App 277
    Danny’s Drywall v. Labor Commission
    “[c]onflicting medical opinions related to a claim of permanent
    total disability.” 
    Id.
     R602-2-2(A)(4).
    ¶14 When a medical panel is convened, “[t]he role of the Medical
    Panel is to ‘evaluat[e] medical evidence’ and ‘advis[e] an
    administrative law judge with respect to the administrative law
    judge’s ultimate fact-finding responsibility.’” Blair, 
    2011 UT App 248
    , ¶ 18 (alterations in original) (quoting Utah Code Ann. § 34A-2-
    601(1)(d)(ii) (Supp. 2010)). “[T]he ALJ/Commission is always the
    ultimate fact finder,” Speirs v. Southern Utah Univ., 
    2002 UT App 389
    , ¶ 10, 
    60 P.3d 42
    , and “[a]lthough an administrative law judge
    is not bound by the panel’s report, she may base her findings and
    decision on it,” Blair, 
    2011 UT App 248
    , ¶ 18 (citing Utah Code Ann.
    § 34A-2-601(2)(e)(i) (Supp. 2010)). Consequently, “[i]t is not unusual
    for an administrative law judge and the Commission to adopt the
    findings of a medical panel.” Id. ¶ 19 (citation and internal
    quotation marks omitted). “However, it is the prerogative and the
    duty of the Commission to consider not only the report of the
    medical panel, but also all of the other evidence and to draw
    whatever inferences and deductions fairly and reasonably could be
    derived therefrom.” Id. (citation and internal quotation marks
    omitted). Indeed, the medical panel’s “proper purpose is limited to
    medical examination and diagnosis, the evidence of which is to be
    considered by the Commission in arriving at its decision.”
    Intermountain Health Care, Inc. v. Board of Review of the Indus.
    Comm’n, 
    839 P.2d 841
    , 845 n.5 (Utah Ct. App. 1992) (citation and
    internal quotation marks omitted).
    ¶15 In this case, the ALJ appointed a medical panel after first
    determining that conflicting medical evidence concerning
    Claimant’s medical and functional limitations required an
    independent review of the medical evidence. The ALJ specifically
    directed the medical panel to answer the following question: “What
    are [Claimant’s] permanent physical restrictions as a result of
    injury from the industrial accident on 2/17/2009?” In Employer’s
    view, the ALJ’s instruction did not allow the panel to consider the
    issues of causation, diagnosis, and past and future medical care. We
    are not persuaded. Instead, we agree with the Commission that the
    ALJ’s charge to the panel consisted of several components,
    20121077-CA                       7                
    2014 UT App 277
    Danny’s Drywall v. Labor Commission
    including the identity of Claimant’s medical problems, the
    likelihood that those problems were “a result of” the industrial
    accident, and an assessment of the physical restrictions resulting
    from those work-related injuries. (Internal quotation marks
    omitted.) Similarly, we agree with the ALJ that it is difficult to
    understand how the panel could perform its job without
    addressing the physical restrictions and whether they were caused
    by the injuries sustained in the industrial accident. Indeed,
    Employer has not identified any statute or rule that the panel’s
    analysis violated. Because the medical panel was responsive to the
    various components of the ALJ’s charging order and because the
    Commission was the ultimate factfinder, we conclude that the
    Commission did not exceed its discretion in determining that the
    causation and diagnosis of Claimant’s conditions were issues
    properly before the medical panel.
    II. Reasonable Medical Probability
    ¶16 Employer challenges the Commission’s conclusion that the
    medical panel report was based on a reasonable medical
    probability rather than on a medical possibility. In support of its
    argument that the medical panel report is speculative and
    uncertain, Employer points to the medical panel report’s use of the
    words “may” and “possible” with regard to Claimant’s physical
    conditions. Because this issue “does not lend itself to consistent
    resolution by a uniform body of appellate precedent,” it is fact-like
    and the Commission’s decision on the issue is entitled to deference.
    See Jex v. Labor Comm’n, 
    2013 UT 40
    , ¶ 15, 
    306 P.3d 799
     (citation and
    internal quotation marks omitted).
    ¶17 Although Employer is correct that the medical panel report
    uses the terms “may” and “possible” on occasion, the medical
    panel begins its report of Claimant’s conditions with the
    unequivocal statement that Claimant “has the following medical
    conditions, as a direct result of the February 17, 2009 industrial
    accident.” When the report is read as a whole, and in light of this
    clear statement that Claimant “has the following medical
    conditions,” it is evident that the medical panel’s opinion is based
    on the panel’s assessment of medical probability. We therefore
    20121077-CA                      8                
    2014 UT App 277
    Danny’s Drywall v. Labor Commission
    disagree with Employer that the Commission’s order should be set
    aside.
    III. The Medical Panel’s Examination
    ¶18 Employer claims that the Commission erroneously adopted
    the medical panel report because the panel relied on statements
    made during its examination of Claimant. When the panel
    interviewed Claimant, Claimant’s family members helped him
    answer questions and stated their observations of his symptoms.
    Employer asserts that the medical panel should not have
    considered these comments because they were outside the record.
    Because the Commission is “in a superior position to decide” this
    question, we defer to its determination. See 
    id.
     (citation and internal
    quotation marks omitted).
    ¶19 The Utah Code allows a medical panel to “conduct a study,”
    “take an x-ray,” or “perform a test.” Utah Code Ann. § 34A-2-
    601(2)(a)(i)–(iii) (LexisNexis Supp. 2013). Accordingly, “a medical
    panel may conduct its own medical examination and review of the
    medical record.” Certified Bldg. Maint. v. Labor Comm’n, 
    2012 UT App 240
    , ¶ 12, 
    285 P.3d 831
    . This court has therefore allowed
    Commission decisions to stand where the medical panel conducted
    its own examination and interview of the claimant. See, e.g., 
    id.
    ¶¶ 12–13 (“[T]he medical panel was provided the medical record
    and was permitted to conduct its own physical examination and
    interview of [the claimant].”).
    ¶20 Employer’s argument that the medical panel improperly
    considered extra-record evidence relies on Utah Code section 63G-
    4-208, which provides that in formal adjudicative proceedings, the
    presiding officer shall issue an order with “findings of fact based
    exclusively on the evidence of record in the adjudicative
    proceedings or on facts officially noted.” Utah Code Ann. § 63G-4-
    208(1)(a) (LexisNexis 2011). If we assume, without deciding, that
    section 63G-4-208 applies to a medical panel report, the report in
    this case was based on “the evidence of record in the adjudicative
    proceedings or on facts officially noted.” See id. (emphasis added).
    The medical panel report expressly noted information that
    20121077-CA                       9                 
    2014 UT App 277
    Danny’s Drywall v. Labor Commission
    originated from statements made by Claimant’s family members
    during the panel’s examination. In doing so, the medical panel
    complied with the ALJ’s instruction that it include in its report any
    “additional facts which are not contrary to the facts in the Findings
    of Fact and Conclusions of Law contained in [her] Interim Order”
    that the panel used in its examination and evaluation. Furthermore,
    medical panels routinely obtain information from interviews with
    claimants, see, e.g., Certified Bldg. Maint., 
    2012 UT App 240
    ,
    ¶¶ 12–13, and Employer has not persuaded us that the medical
    panel in this case impermissibly gathered a medical history that
    conflicted with the ALJ’s interim findings.
    ¶21 Employer nonetheless asserts that the medical panel’s
    consideration of the family members’ statements violated its
    statutory right to cross-examine witnesses. In support, Employer
    cites section 63G-4-206 of the Utah Administrative Procedures Act
    (the UAPA). This section provides that “in all formal adjudicative
    proceedings, a hearing shall be conducted” during which all parties
    are afforded “the opportunity to present evidence, argue, respond,
    conduct cross-examination, and submit rebuttal evidence.” Utah
    Code Ann. § 63G-4-206(1)(d) (LexisNexis 2011). Under the UAPA,
    an “‘[a]djudicative proceeding’ means an agency action or
    proceeding described in Section 63G-4-102.” Id. § 63G-4-103(1)(a).
    Section 63G-4-102, in turn, does not say anything about a medical
    panel’s examination. Id. § 63G-4-102 (LexisNexis Supp. 2013).
    Employer relies on section 63G-4-206 for its claim that it was
    entitled to cross-examine the family members, but by its plain
    language, the section applies only to formal adjudicative
    proceedings. Id. § 63G-4-206. Employer does not explain how a
    medical panel’s examination of a claimant, conducted pursuant to
    section 34A-2-601(2)(a), constitutes a formal adjudicative
    proceeding during which an employer must be afforded an
    opportunity to cross-examine all those present. Employer therefore
    has not convinced us that section 63G-4-206 requires the ALJ and
    the Commission to afford parties the opportunity to cross-examine
    individuals present at a medical panel’s examination of a claimant.
    ¶22 Employer also contends that the Commission violated its
    right to constitutional due process by permitting the medical panel
    20121077-CA                      10               
    2014 UT App 277
    Danny’s Drywall v. Labor Commission
    to solicit information from Claimant’s family members without
    giving Employer an opportunity to cross-examine them. Employer,
    however, has not demonstrated that it sufficiently preserved the
    issue during the proceedings before the Commission.
    ¶23 “[T]he preservation rule applies to every claim, including
    constitutional questions . . . .” State v. Holgate, 
    2000 UT 74
    , ¶ 11, 
    10 P.3d 346
    . “We do not review an unpreserved issue unless
    exceptional circumstances are present or the error was plain.” Utah
    Chapter of Sierra Club v. Air Quality Bd., 
    2009 UT 76
    , ¶ 26, 
    226 P.3d 719
    . “[T]o preserve an issue for judicial review it must be raised in
    a timely fashion before the agency, and be specifically raised with
    supporting evidence or relevant legal authority.” Wintle-Butts v.
    Career Serv. Review Office, 
    2013 UT App 187
    , ¶ 13 n.4, 
    307 P.3d 665
    (citation and internal quotation marks omitted). “In short, a party
    may not claim to have preserved an issue for appeal by merely
    mentioning . . . an issue without introducing supporting evidence
    or relevant legal authority.” Pratt v. Nelson, 
    2007 UT 41
    , ¶ 15, 
    164 P.3d 366
     (omission in original) (citation and internal quotation
    marks omitted).
    ¶24 In its motion for review before the Commission, Employer
    stated that “[a]ny medical or factual information solicited from any
    third party family member who attended the evaluation is in
    violation of [Employer’s] right to state and federal due process and
    violation of the Utah Administrative Procedures Act.” Although
    Employer cited section 63G-4-206 as supporting authority for its
    statutory right to cross-examine witnesses under the UAPA,
    Employer failed to argue how its constitutional due process rights
    were violated. As a result, the Commission did not have the
    opportunity to address Employer’s constitutional argument.
    Because Employer did not adequately preserve this issue before the
    Commission, we decline to reach the merits of Employer’s
    constitutional due process argument.
    IV. Adequacy of the Interim Order
    ¶25 Next, Employer argues that the ALJ provided insufficient
    findings of fact in her Interim Order. Specifically, Employer argues
    20121077-CA                       11                
    2014 UT App 277
    Danny’s Drywall v. Labor Commission
    that the Interim Order “failed to identify for the panel those
    conditions which were caused by the industrial accident” and that
    this error prejudiced Employer because it caused the medical panel
    to “stray[] beyond the Interim Order and erroneously mak[e] its
    own factual findings regarding [the] issue[].”
    ¶26 In this case, the Interim Order did not contain findings as to
    the nature of Claimant’s diagnoses, whether his various medical
    problems were caused by his work accident, or what effect those
    medical problems had on his ability to work. Employer argues that
    these omissions render the ALJ’s Interim Order insufficiently
    detailed. Employer, however, failed to preserve this argument
    before the ALJ or the Commission. As discussed, an argument is
    preserved for judicial review if it is has been “raised in a timely
    fashion before the agency, and [has been] specifically raised with
    supporting evidence or relevant legal authority.” Wintle-Butts, 
    2013 UT App 187
    , ¶ 13 n.4 (citation and internal quotation marks
    omitted). In its reply memorandum in support of its objection to
    the medical panel report, Employer stated, “In this case, the interim
    order and charging instructions were insufficient to provide
    guidance as to what conditions were causally related to the
    industrial accident.” (Emphasis omitted.) Employer did not
    support this claim with any relevant legal authority. Employer
    made the same assertion, again without supporting legal authority,
    in its reply to Claimant’s objection to the motion for review.
    Employer therefore has not preserved this argument for judicial
    review.
    ¶27 But even if we were to consider this argument, we could not
    agree with Employer that the medical panel strayed beyond the
    Interim Order, because the ALJ specifically asked the medical panel
    to evaluate Claimant’s “permanent physical restrictions as a result
    of injury from the industrial accident.” In other words, the medical
    panel was instructed to make findings on “those conditions which
    were caused by the industrial accident.” Any deficiency in the
    ALJ’s factual findings would therefore be harmless. See Certified
    Bldg. Maint. v. Labor Comm’n, 
    2012 UT App 240
    , ¶¶ 9–11, 
    285 P.3d 831
     (employing the harmlessness standard when there was a claim
    20121077-CA                      12               
    2014 UT App 277
    Danny’s Drywall v. Labor Commission
    that an ALJ’s interim findings were inadequate); Blair v. Labor
    Comm’n, 
    2011 UT App 248
    , ¶ 16, 
    262 P.3d 456
     (same).
    V. Substantial Evidence
    ¶28 Employer argues that the Commission erred in adopting the
    medical panel’s report “when there was other substantial evidence
    supporting a finding contrary to the medical panel’s [finding].” In
    support, Employer cites Dr. Chung’s analysis and other evidence
    it claims conflicts with the panel’s findings regarding Claimant’s
    functional and medical capacity.
    ¶29 As we have explained, “[a]n administrative law judge may
    base [his or her] finding and decision on the report of . . . a medical
    panel.” Utah Code Ann. § 34A-2-601(2)(e)(i)(A) (LexisNexis Supp.
    2013). Nevertheless, “an administrative law judge is not bound by
    a report . . . if other substantial conflicting evidence in the case
    supports a contrary finding.” Id. § 34A-2-601(2)(e)(ii). Employer
    points to this language referring to “other substantial conflicting
    evidence” and asserts that “other substantial conflicting evidence”
    exists in this case that supports a finding contrary to the panel’s
    finding. This “other substantial conflicting evidence,” Employer
    contends, precluded the ALJ from admitting and considering the
    medical panel report.
    ¶30 The statutory language that an administrative law judge “is
    not bound by a [medical panel] report . . . if other substantial
    conflicting evidence . . . supports a contrary finding,” id., is more
    pertinent to circumstances where the administrative law judge has
    adopted a finding contrary to the medical panel report. See, e.g.,
    Greyhound Lines, Inc. v. Wallace, 
    728 P.2d 1021
    , 1022–23 (Utah 1986)
    (rejecting a plaintiff’s challenge to a finding where the Commission
    chose to accept statements of one physician instead of the medical
    panel report); Straub v. Labor Comm’n, 1999 UT App 192U, paras.
    2–4 (refusing to grant relief where a petitioner argued that the
    ALJ’s findings were contrary to those rendered by the medical
    panel and that the ALJ was bound by the medical panel’s findings).
    The presence of conflicting evidence does not negate the
    administrative law judge’s discretion to base his or her findings on
    20121077-CA                       13                
    2014 UT App 277
    Danny’s Drywall v. Labor Commission
    the medical panel report. See Utah Code Ann. § 34A-2-601(2)(e).
    We agree with the Commission that the existence of conflicting
    evidence is not “a sufficient reason to disregard a medical panel
    report or exclude the report from the evidence.” This is especially
    true in light of the fact that medical panels are used precisely
    because there are conflicting medical opinions. See Utah Admin.
    Code R602-2-2 (stating that a medical panel will be utilized by an
    administrative law judge when a significant medical issue has been
    shown by conflicting medical reports).
    ¶31 Employer’s argument that substantial evidence contradicts
    the medical panel’s report boils down to an argument that “more
    weight should have been given to the evidence in its favor.” See
    Timpanogos Hosp. v. Labor Comm’n, 
    2011 UT App 106
    , ¶ 7, 
    251 P.3d 855
    . But this court may not reweigh the evidence because
    “assigning such weights is the prerogative of the Commission.” Id.;
    see also Migliaccio v. Labor Comm’n, 
    2013 UT App 51
    , ¶ 7, 
    298 P.3d 676
     (“It is not the role of this court to reweigh the evidence and
    substitute our conclusion for that of the Commission.” (citation
    and internal quotation marks omitted)). Employer has failed to
    demonstrate that the Commission’s findings are not supported by
    substantial evidence. See Swift Transp. v. Labor Comm’n, 
    2014 UT App 104
    , ¶ 8, 
    326 P.3d 678
     (“We will not disturb the Commission’s
    factual findings unless the party challenging the findings
    demonstrates that a finding is not supported by substantial
    evidence.”). Accordingly, we will not set aside the Commission’s
    findings.
    VI. Attorney Fees
    ¶32 As a final matter, Claimant requests an award of attorney
    fees and costs incurred on appeal pursuant to rules 33 and 34 of the
    Utah Rules of Appellate Procedure. Claimant asserts that
    Employer’s petition for judicial review is frivolous and that he is
    therefore entitled to attorney fees and costs.
    ¶33 Rule 33 provides that if an appellate court determines that
    an appeal is “either frivolous or for delay, it shall award just
    damages, which may include single or double costs, as defined in
    20121077-CA                     14                
    2014 UT App 277
    Danny’s Drywall v. Labor Commission
    Rule 34, and/or reasonable attorney fees, to the prevailing party.”
    Utah R. App. P. 33(a). A frivolous appeal is “one that is not
    grounded in fact, not warranted by existing law, or not based on
    a good faith argument to extend, modify, or reverse existing law.”
    
    Id.
     R. 33(b). “But the imposition of such a sanction is a serious
    matter and only to be used in egregious cases, lest the threat of
    such sanctions should chill litigants’ rights to appeal lower court
    decisions.” Redd v. Hill, 
    2013 UT 35
    , ¶ 28, 
    304 P.3d 861
    . “Sanctions
    are appropriate [only] for appeals obviously without merit, with
    no reasonable likelihood of success, and which result in the delay
    of a proper judgment.” 
    Id.
     (citation and internal quotation marks
    omitted). Claimant has not demonstrated that this is an “egregious
    case[],” and we therefore conclude that Claimant is not entitled to
    an award of attorney fees. See 
    id.
     However, we grant Claimant’s
    request for costs incurred on appeal because we are not disturbing
    the Commission’s order. See Utah R. App. P. 34(a) (“[I]f a judgment
    or order is affirmed, costs shall be taxed against appellant unless
    otherwise ordered . . . .”); see also 
    id.
     R. 34(e) (“In all other matters
    before the court, including appeals from an agency, costs may be
    allowed as in cases on appeal from a trial court.”).
    CONCLUSION
    ¶34 For the foregoing reasons, we allow the Commission’s order
    to stand.
