    CASIE O’NEIL
    FROM THE VIRGINIA WORKERS’ COMPENSATION COMMISSION
    Brian J. McNamara (Scott C. Ford; Ford Richardson, P.C., on
    brief), for appellants.
    Casie O’Neil, pro se.
    The County of Henrico and PMA Management Corporation, TPA (referred to
    collectively as “Henrico County”) appeal a decision of the Virginia Workers’ Compensation
    Commission (“the Commission”) awarding Casie O’Neil benefits for injuries from an accident
    arising out of and in the course of her work. On appeal, Henrico County argues that the
    Commission erred by concluding that O’Neil’s claim for benefits was not barred by res judicata.
    Henrico County also contends that the Commission erred by refusing to permit the County to
    participate in oral argument in an unrelated case and that the Commission erred by finding that
    O’Neil’s injuries were causally related to her workplace accident. For the following reasons, we
    affirm the Commission’s decision.
    BACKGROUND
    I. Medical History
    On March 24, 2017, O’Neil, a sheriff’s deputy, attended a sheriff’s training exercise.
    During the training, a lieutenant punched her near the throat, causing pain in her collarbone,
    neck, head, left arm, and ear. Immediately following the punch, O’Neil felt pain on her left side,
    she could not hear anything, and her jaw hurt. Her supervisors instructed her to go back to her
    workplace to fill out an incident report. She experienced more pain while driving, so she pulled
    over and her supervisor drove her to the emergency room where she was treated by C. Bruce
    Spiller, a nurse practitioner.
    After the first visit, NP Spiller’s physician’s forms from March 24 to March 28 indicated
    that she had “left clavicle contusion/pain” and restricted O’Neil to “light duty” status. The forms
    also stated that O’Neil should not lift anything over five pounds and that she should avoid using
    her left arm. NP Spiller referred O’Neil to an orthopedic specialist, Dr. Stephen Reese, who, on
    March 30, 2017, diagnosed her with a brachial plexus injury and sternoclavicular joint strain.
    Dr. Reese’s notes recounted the training incident under the heading “onset.”
    Next, upon Dr. Reese’s recommendation, O’Neil visited Anne Stuart, a physical
    therapist. Ms. Stuart’s notes indicated that O’Neil suffered a brachial plexus and
    sternoclavicular injury after a hit to her throat and, in the same paragraph, stated, “CC limited
    movement left arm. Waking up due to left arm pain. Tingling intermittent to index finger.” On
    April 11, 2017, O’Neil again visited Dr. Reese, who diagnosed her with a brachial plexus injury
    and radicular pain of her left upper extremity.
    Then, around April 20, 2017, O’Neil’s doctors performed an MRI exam, which indicated
    “multilevel degenerative disc disease in the spine” and led Dr. Reese to also diagnose O’Neil
    with “strain of muscle / fascia and tendon at neck level / subsequent encounter.” Again,
    Dr. Reese referred to the training incident under the heading “onset.” He also referred her to a
    pain specialist, who narrated the training incident under the heading “problem story” and who
    believed she “suffer[s] from a brachial plexopathy.”
    -2-
    Around May 31, 2017, O’Neil underwent electrodiagnostic studies, which indicated a
    normal nerve exam. In the notes under “diagnosis,” the attending physician noted “pain in left
    arm” and “hypoesthesia [numbness] of skin.” The physician also noted that O’Neil’s pain was
    associated with a workplace injury from March 24, 2017. Around July 10, 2017, Dr. Reese
    approved O’Neil to return to full-duty work.
    On October 31, 2017, O’Neil visited Dr. Anthony Julius, a neurologist. He diagnosed her
    with a brachial plexus injury, reactive cervical lymphadenopathy, neuropathic pain, and otalgia
    of the left ear. Like the other doctors, Dr. Julius noted in the report that O’Neil’s pain began
    with the training incident. He also wrote, “I believe her pain is most consistent with an injury of
    the brachial plexus with neuralgia.” He then referred her to an ear, nose, and throat specialist
    (ENT).
    On November 15, 2017, O’Neil visited Dr. Wayne T. Shaia, an ENT, who noted the
    training incident and diagnosed her with “vertigo of central origin,” tinnitus, unilateral
    sensorineural hearing loss in her left ear, and left ear otalgia. On November 28, 2017, O’Neil
    returned to Dr. Shaia, who diagnosed her with “labyrinthine dysfunction” and “otalgia” in her
    left ear. She also underwent videonystagmography testing, which showed an abnormality in her
    left ear.
    II. Procedural History
    On April 20, 2017, O’Neil filed a “Claim for Benefits” with the Workers’
    Compensation Commission, claiming injuries to her neck, collarbone, and upper left extremity.
    After her filing, the parties entered into a voluntary award agreement that provided temporary
    total disability due to “sternoclavicular joint strain.” The Commission approved the agreement
    on June 20, 2017. An evidentiary hearing was never scheduled.
    -3-
    Beginning in February 2018, O’Neil filed three more claims requesting compensation for
    injuries related to the same incident. The first two claims were withdrawn without prejudice; the
    third claim is at issue here. This claim sought compensation for injuries sustained to her brachial
    plexus, neck, collarbone, left upper extremity, left ear, and mouth as part of the original March
    24, 2017 accident and compensation for a brain injury as a compensable consequence of the
    accident. A deputy commissioner held an evidentiary hearing on April 9, 2019, where O’Neil
    withdrew her claim for the brain injury. On October 21, 2019, the deputy commissioner entered
    an opinion denying O’Neil’s claims based on res judicata. The same day, O’Neil filed a request
    for review with the Commission.
    On March 6, 2020, the Commission reversed the deputy commissioner’s opinion and
    found that res judicata did not apply to O’Neil’s claims. The case was remanded to the deputy
    commissioner, who denied the claim because O’Neil failed to prove that any injuries to her
    brachial plexus, neck, collarbone, left arm, left ear, or mouth were directly related to the incident
    or a compensable consequence of that incident. On August 5, 2020, the full Commission
    partially reversed the deputy commissioner, finding that O’Neil sufficiently proved compensable
    injuries to her brachial plexus, neck, collarbone, and left arm, but affirming that she did not
    prove compensable injury to her left ear or mouth. This appeal timely followed.
    ANALYSIS
    On appeal, Henrico County contends that the Commission erred in hearing and deciding
    O’Neil’s claims for benefits. The County argues that O’Neil’s claims for benefits for injuries to
    her brachial plexus, neck, collarbone, and left arm are barred by the res judicata doctrine of claim
    preclusion. Henrico County also argues that it was denied the opportunity for oral argument in a
    different case the Commission determined to hear before rendering a decision in this case. It
    -4-
    argues that O’Neil failed to prove the causal connection between the injuries to her brachial
    plexus, neck, collarbone, and left upper extremities and her workplace accident.
    I. Res judicata does not apply to bar to O’Neil’s claims.
    A. Res Judicata as Applied in Workers’ Compensation Cases Generally
    We first address Henrico County’s contention that the principles of res judicata bar
    O’Neil’s claims for benefits for all injuries except those specifically resolved by the voluntary
    award agreement. The application of res judicata is a question of law we review de novo.
    Advance Auto & Indem. Ins. Co. v. Craft, 
    63 Va. App. 502
    , 514 (2014).
    “[R]es judicata is a judicially created doctrine resting upon public policy considerations
    which favor certainty in the establishment of legal relations, demand an end to litigation, and
    seek to prevent harassment of parties.” 
    Id. at 514-15
     (quoting K & L Trucking Co. v. Thurber, 
    1 Va. App. 213
    , 219 (1985)). “[T]he doctrine is firmly established in our jurisprudence and should
    be maintained where applicable.” Thurber, 1 Va. App. at 219. It includes “[t]wo distinct
    concepts—issue preclusion and claim preclusion.” Brock v. Voith Siemens Hydro Power
    Generation, 
    59 Va. App. 39
    , 45 (2011). Issue preclusion, also referred to as “collateral
    estoppel,” precludes the same parties from re-litigating “any issue of fact actually litigated and
    essential to a valid and final personal judgment in the first action.” 
    Id.
     (quoting Rawlings v.
    Lopez, 
    267 Va. 4
    , 4-5 (2004)). In contrast, claim preclusion precludes a party from continuing to
    litigate claims stemming from the same cause of action against the same party. See Bates v.
    Devers, 
    214 Va. 667
    , 670-71 (1974). Claim preclusion, also referred to as “merger” or “bar,”
    “treats unasserted claims as being subsumed into the disposition of related, previously
    adjudicated, claims arising out of the same cause of action.” Brock, 59 Va. App. at 45.1 “Claims
    1
    Rule 1:6 codified the common law doctrine of res judicata. Where we have previously
    balanced res judicata against competing policy considerations, those limits to res judicata apply
    -5-
    precluded by res judicata include those ‘made or tendered by the pleadings,’ as well as those
    ‘incident to or essentially connected with the subject matter of the litigation.’” Id. at 46 (quoting
    Lofton Ridge, LLC v. Norfolk S. Ry., 
    268 Va. 377
    , 381 (2004)).
    We have held that the principles of res judicata apply to workers’ compensation cases.
    See Rusty’s Welding Serv., Inc. v. Gibson, 
    29 Va. App. 119
    , 128 (1999) (en banc); Craft, 63
    Va. App. at 515. Yet we have also recognized that when res judicata conflicts with other public
    policy considerations, we must balance application of the doctrine against those other
    considerations. See Bates, 
    214 Va. at
    670 n.2 (“We recognize[] that in an appropriate case, res
    judicata, a doctrine based on public policy, may give way when in irreconcilable conflict with
    other, more important public policies.”). The Workers’ Compensation Act was enacted for
    humanitarian purposes and is therefore liberally construed. Fauver v. Bell, 
    192 Va. 518
    , 522
    (1951). The Act represents a compromise, where employers surrender certain defenses and
    employees may recover less than was available at common law. 
    Id.
     As our Supreme Court
    noted, “[a]n essential element of this compromise is the employer’s obligation to pay for
    compensable injuries at a rate contemplated by the Act.” John Driggs Co., Inc. v. Somers, 
    228 Va. 729
    , 735 (1985). When claimants come before the Commission, they are injured and either
    unable to work or unable to work at full capacity. This reality limits a claimant’s bargaining
    power. See Craft, 63 Va. App. at 518-19. An injured claimant is more likely to need immediate
    compensation and, absent protective public policy measures, may “be forced by their
    circumstances to agree to [immediate] awards that only provide compensation for some of their
    work-related injuries.” Id. Thus, we have determined that “[t]he principles of res judicata
    should not be applied in a way that facilitates such inequitable results.” Id. at 519.
    to Rule 1:6. See Funny Guy, LLC v. Lecego, LLC, 
    293 Va. 135
    , 150 n.15 (“All of the ordinary
    caveats to res judicata apply to Rule 1:6’s transactional approach to merger and bar.”).
    -6-
    We recognize that a “[w]orkers’ compensation case, of course, cannot always be
    concluded in a single evidentiary hearing,” and have therefore affirmed the Commission’s
    “tailored . . . application of res judicata to take into account allegations of injury that, while pled
    in the initial claim may nonetheless not be ripe for final adjudication.” Brock, 59 Va. App. at
    49.2 Recognizing the need to balance finality in litigation against the established public policy
    considerations that undergird the purpose of the Workers’ Compensation Act, this Court has
    limited the application of res judicata as a bar to claimant’s relief to two scenarios: 1) in a final
    judgment after a party has pursued and submitted a claim at an evidentiary hearing or 2) when a
    claim is considered waived or abandoned. Craft, 63 Va. App. at 517. 3
    “A final judgment based on a determination by the [C]omission . . . conclusively resolves
    the claim as to that particular injury,” so that “nothing more is necessary to settle the rights of the
    parties or the extent of those rights.” AMP, Inc. v. Ruebush, 
    10 Va. App. 270
    , 274 (1990) (citing
    Thurber, 1 Va. App. at 219); Gibson, 29 Va. App. at 128 (quoting 8B Michie’s Jurisprudence,
    Former Adjudication or Res Judicata § 13 (1994)) (holding that the Commission did not err in
    determining that a deputy commissioner’s order stating, “claim denied . . . at this time” was not a
    final determination on the merits).
    Even when not fully litigated on the merits, a claim for benefits may be barred by res
    judicata when it is considered abandoned or waived. Whether a claimant has abandoned or
    2
    We have recognized that among the “protective measures” available to avoid finally
    deciding matters “unripe for adjudication” include the Commission’s authority to defer
    premature issues and to permit claimants to voluntarily withdraw claims before a matter has
    closed and been submitted for decision. See Brock, 59 Va. App. at 49 (citing Brown v. United
    Airlines, Inc., 
    34 Va. App. 273
     (2001); Jenkins v. Webb, 
    47 Va. App. 404
    , 407 (2006)). We note
    that here, O’Neil seized on at least one of these protective measures. We are not inclined to
    apply res judicata principles to penalize her for the same.
    3
    To the extent that Craft and Shy v. Starbucks Coffee Co., 
    61 Va. App. 229
     (2012),
    conflict, we find Craft more persuasive given the facts in this case, and consequently, Craft
    controls here.
    -7-
    waived her injury claim is rarely a matter of explicit statement but may be construed from a
    party’s conduct.
    A claimant abandons her claim when the claim proceeds to an evidentiary hearing and the
    claimant fails to present evidence for all the injuries asserted in her claim for benefits. Brock, 59
    Va. App. at 49 (applying res judicata to bar claims brought in a second hearing after the claimant
    was warned that “[a]ll issues will be considered,” at his first evidentiary hearing). Similarly, a
    claimant may abandon her claims when she represents to the Commission that an award
    agreement encompasses all her injury claims. See Tuck v. Goodyear Tire & Rubber Co., 
    47 Va. App. 276
    , 284 (2008) (holding that the Commission did not err in finding no proof of
    “mutual mistake” where the claimant represented to the Commission that “all issues were
    resolved” by the award agreement).
    Waiver, in comparison, “is an intentional relinquishment of a known right.” Orthopaedic
    & Spine Ctr. v. Muller Martini Mfg. Corp., 
    61 Va. App. 482
    , 492 (2013). It is characterized by
    “voluntary action or inaction with intent to surrender a right in esse with knowledge of the facts
    and circumstances which gave birth to the right. . . . In waiver, both knowledge of the facts basic
    to the exercise of the right and the intent to relinquish that right are essential elements. . . .”
    Roske v. Culbertson Co. & Va. Sur. Co., Inc., 
    62 Va. App. 512
    , 518 (2013) (quoting Employers
    Com. Union Ins. Co. v. Great Am. Ins. Co., 
    214 Va. 410
    , 412-13 (1973)). Without “clear,
    precise and unequivocal evidence” of intent to surrender a known right, we have not interpreted a
    party’s conduct, such as signing a memorandum of agreement, as waiving a right not explicitly
    contained within the agreement. 
    Id. at 520
     (quoting Utica Mut. v. Nat’l Indem., 
    210 Va. 769
    ,
    733 (1970)). Our holding in Craft is exemplary of this notion.
    In Craft, the claimant entered into a voluntary award agreement with the employer and
    then, approximately twenty-two months later, filed a claim for benefits with the Commission
    -8-
    seeking an award for additional, separate injuries stemming from the same accident. 63
    Va. App. at 512-13. The full Commission upheld the subsequent award, holding that because the
    claimant had not filed a claim when the award order was entered, the claimant had not waived
    her rights to the additional injury claims not covered by the award agreement, and the doctrine of
    res judicata did not apply. Id. at 513. The employer then appealed to this Court.
    In affirming the Commission’s holding, we found the procedural posture of the case
    significant and distinguished it from our prior precedent. We reasoned that “[the claimant] had
    not yet put all of her injuries at issue before the [C]ommission or had the opportunity to advance
    her claims by presenting evidence of her injuries at an evidentiary hearing. . . . [T]herefore she
    cannot be deemed to have abandoned or otherwise waived those claims.” Id. at 517-18. Put
    another way, res judicata does not apply until a claimant abandons or waives her claims.
    B. Res Judicata as Applied in O’Neil’s Case.
    Turning now to the matter before us and applying the principles presented above, we
    conclude, like the Commission, that res judicata does not apply to bar O’Neil’s claims for
    injuries to her brachial plexus, neck, collarbone, and left arm. Here we face a similar scenario as
    presented in Craft, except that O’Neil filed her claim before entering into a voluntary award
    agreement with Henrico County. Henrico County presented this appeal to resolve a question that
    the Commission has faced since our decision in Craft: If a claimant files a claim but enters into
    an award agreement before an evidentiary hearing is scheduled on the claim, does res judicata
    preclude the claimant from filing additional claims? For four reasons, we conclude that it does
    not.
    First, like the claimant in Craft, O’Neil had not yet presented all her claims to the
    Commission for adjudication. When the parties signed the award agreement and the deputy
    commissioner approved and entered the award, O’Neil had taken no action on the claim and an
    -9-
    evidentiary hearing had not yet been scheduled. Indeed, O’Neil did not request to schedule an
    evidentiary hearing until about eight months after entry of the agreement award. And when her
    request to continue the first scheduled evidentiary hearing was denied, O’Neil withdrew her
    claims and filed a new claim for benefits that included the original unresolved injury claims from
    her original filing.
    Henrico County argues that under Craft, O’Neil’s act of filing the initial claim for
    benefits triggers the application of res judicata principles to bar her from further relief. We find
    this an incongruous interpretation of the case. Craft does not hold that filing a claim always
    triggers res judicata; it holds that res judicata cannot be triggered before a claim is filed. See
    Craft, 63 Va. App. at 517-18 (“As Craft had not yet filed a claim with the [C]ommission at the
    time of the award agreement and the subsequent entry of the award order, there were no claims
    pending with the [C]ommission that could later be barred by the principles of res judicata.”).
    Simply filing a claim and then signing an award agreement does not trigger res judicata.
    Second, O’Neil neither waived nor abandoned her injury claims related to her brachial
    plexus, neck, collarbone, and left arm. Although she pursued her claims, O’Neil’s case never
    progressed to an evidentiary hearing. And despite entering into an award agreement, she never
    “represent[ed] that the agreement forms resolve the claims.” Nor do we find O’Neil’s action in
    signing the award agreement constitutes her intentional relinquishment of her right to claim
    additional injuries before submission of her claim for adjudication. Cf. Binswanger Glass Co. v.
    Wallace, 
    214 Va. 70
    , 74 (1973) (holding that the voluntary execution of a supplemental
    memorandum of agreement and the voluntary payment of compensation after the statutory time
    limitation for compensation constituted waiver by the employer of right to enforce time bar).
    The award agreement did not notify O’Neil that by signing it she would be precluded
    from claiming additional injuries. And, since Craft, the Commission has continually allowed
    - 10 -
    claimants to file a claim, sign an award agreement resolving some injury claims, and file new or
    additional claims for unresolved injuries. See Williams v. Drug Transp. Inc., JCN
    VA00000553371, slip op. at 1-2 (Va. Workers Comp. Comm’n Jan. 16, 2014), aff’d,
    No. 1790-14-2 (Va. Ct. App. Feb. 18, 2015)4; Clute v. Big Lots Stores, Inc., JCN
    VA00000420654, slip op. at 4 (Va. Workers Comp. Comm’n June 5, 2014), aff’d, No. 0206-15-2
    (Va. Ct. App. June 9, 2015); Lumpkin v. Amerigas Propane, JCN VA00000485920, slip op. at 6
    (Va. Workers Comp. Comm’n Feb. 27, 2014); Hall v. Structural Concrete Products, Inc., JCN
    VA00000662154, slip op. at 4 (Va. Workers Comp. Comm’n Apr. 28, 2015). A claimant does
    not, by merely signing an award agreement to resolve some injury claims, knowingly or
    intentionally waive her rights for claims not addressed by the agreement. Instead, a claimant’s
    intent to waive or abandon her claim must be evident, such as by an explicit waiver provision in
    the agreement.5 Therefore we find that O’Neil took no action that constitutes waiver or
    abandonment of her claims.
    Third, and contrary to Henrico County’s argument, our decision in Levy v. Wegman’s
    Food Markets, Inc., 
    68 Va. App. 575
     (2018), is inapplicable here. In Levy, the Commission,
    4
    As a policy argument, Henrico County claims that Williams discourages employers
    from entering into voluntary agreements. But Henrico County does not point to any evidence
    that voluntary settlements have meaningfully decreased since Williams was decided. In 2015,
    the year that this Court affirmed Williams, the Commission boasted 5,646 settlements. See
    Virginia’s Workers’ Compensation Commission, Annual Report 20 (2015). In 2017, two years
    later, Henrico County and O’Neil entered the award agreement here, one of 5,699 settlements
    from that year. See Virginia’s Workers’ Compensation Commission, Annual Report 17 (2017).
    Between 2015 and 2020, the most recent year with reported data, there was no meaningful
    change in the number of settlements coming from the Commission. See Virginia’s Workers’
    Compensation Commission, Annual Report 20 (2015); Virginia’s Workers’ Compensation
    Commission, Annual Report 12 (2020). The data does not support Henrico County’s argument
    that employers hesitate to enter into award agreements after Williams.
    5
    Henrico County hypothesizes that such decision will require future parties to fully
    litigate each injury claim to fully dispose of a claim. Nothing in our holding here limits the use
    of explicit waiver provisions in award agreements if the parties find it prudent and the
    Commission approves.
    - 11 -
    following an evidentiary hearing on the merits, concluded that one of claimant’s injury claims
    was unsupported by the evidence. 68 Va. App. at 578. The claimant then filed a new claim for
    the same injury, this time including evidence of her claim. Id. at 579-80. On appeal, we
    affirmed the Commission’s holding that her claim was barred by res judicata because her first
    iteration of the claim was explicitly denied. Id. at 584. We held that when medical evidence is
    considered by the Commission and found wanting, a claimant is precluded from asserting the
    same claim supported by supplemental medical evidence and considering it a “new” claim. Id.
    (finding that where the Commission previously addressed causation in an evidentiary hearing,
    “neither the issue of causation nor the evidence . . . may be fairly categorized as ‘new’”).
    Levy is readily distinguishable from this case. Unlike O’Neil, the claimant in Levy never
    signed an award agreement, the central document at issue here. Because of that the Commission
    in Levy explicitly considered and denied the claimant’s injury claim following an evidentiary
    hearing. Id. at 582. Here, O’Neil merely filed a claim alleging certain injuries. Then, she signed
    an award agreement. That the award agreement was silent on some injuries is not analogous to
    the Commission’s explicit finding that Levy’s claims were unsupported by the evidence. See id.
    O’Neil’s case is much more analogous to Craft. “[O’Neil] had not yet put all of her injuries at
    issue before the [C]ommission or[, unlike the employee in Levy,] had the opportunity to advance
    her claims by presenting evidence of her injuries at an evidentiary hearing.” Craft, 63 Va. App.
    at 517.
    Finally, we are persuaded that the same public policy considerations recognized in Craft
    apply equally here, so that a claim not otherwise waived or abandoned may not be barred by res
    judicata before an evidentiary hearing. Because the Workers’ Compensation Act “encourages
    the voluntary settlement of claims arising from compensable injuries,” strict application of res
    - 12 -
    judicata would contradict that purpose, allowing award agreements to become a “blanket
    release” for latent injuries or uncertain diagnoses. Id. at 518. Then
    employees would have to ensure that those agreements covered all
    of the potential injuries resulting from their work-related
    accidents. . . . The increased diligence . . . coupled with uncertain
    medical diagnoses and potentially latent injuries would discourage
    the voluntary settlement of claims in many cases. In turn, the
    efficient administration of the Act would be jeopardized as more
    claims would be fully litigated, even when the parties of the case
    were in agreement concerning some injuries involved in the claim.
    Id. Additionally, the Commission would have to closely scrutinize each agreement because
    some claimants may feel pressured to abandon their long-term interests in favor of partial
    awards. Id. at 519. And the Act requires that the Commission only approve agreements in the
    best interest of the employee. Id.; Code § 65.2-701(A). To subvert Craft now and adopt a less
    “tailored” application of res judicata in workers’ compensation cases would be to disregard the
    policy considerations underpinning the Workers’ Compensation Act and degrade the
    Commission’s charge to promote settlements that are in the best interest of the employee.6 Thus,
    we decline to do so here.
    The Commission did not err in finding that O’Neil’s claims were not barred by res
    judicata.
    II. The Commission did not violate Henrico County’s right to due process.
    On December 23, 2019, counsel for O’Neil wrote to the Commission explaining that he
    had three active cases in which the scope of res judicata was the primary issue. He effectively
    requested that the Commission hold its ruling on this case until after oral argument in Viera Lazo
    v. Wholesome Energy LLC. O’Neil’s counsel also proposed that the Commission hear oral
    argument from Henrico County’s counsel, as part of the Viera Lazo case. The Commission
    6
    We note that Code § 65.2-706.2 was enacted after the Commission’s final order and it
    was not briefed by the parties. We therefore do not consider it here.

    agreed to reserve judgment until after the Viera Lazo oral argument but declined to hear oral
    argument from Henrico County as part of those separate proceedings.
    Henrico County asserts that its procedural due process rights were violated when the
    Commission “decid[ed] the case, in part based upon the outcome of an oral argument at which
    the defendants were not afforded the opportunity to be heard.” “Whether a person has been
    deprived of due process is a question of law” that we review de novo. Bragg Hill Corp. v. City
    of Fredericksburg, 
    297 Va. 566
    , 585 (2019).
    We find that Henrico County’s procedural due process rights were not violated.7 Henrico
    County points to no authority that states individuals have the right to present oral argument at a
    case in which the individual’s only interest is the development of the law. The Commission’s
    rules also make it clear that only parties to an action may present oral argument. See Va. Work.
    Comp. Comm. R. 3.4 (“If oral argument is requested and the Commission considers it necessary
    or of probable benefit to the parties or to the Commission in adjudicating the issues, the parties
    will be scheduled to present oral argument.” (emphasis added)). “Our Supreme Court has
    identified ‘the minimum requirements of constitutional due process which must attend
    administrative hearings: timely and adequate notice, the right to confront adverse witnesses and
    present one’s own evidence, the right to the assistance of retained counsel, and an impartial
    decision-maker.’” Virginia Bd. of Medicine v. Zackrison, 
    67 Va. App. 461
    , 482-83 (2017)
    (quoting Hladys v. Commonwealth, 
    235 Va. 145
    , 147 (1988)).
    7
    Although we have previously addressed procedural due process claims from local
    governments in the workers’ compensation context, we have not discussed whether a local
    government indeed has due process rights. Here we assume without deciding that Henrico
    County is entitled to certain due process protections. See Henrico v. Taylor, 
    34 Va. App. 233
    ,
    236 (2001); Nelson Cnty. Schs. v. Woodson, 
    45 Va. App. 674
    , 677 (2005). But cf. City of
    Trenton v. State of New Jersey, 
    262 U.S. 182
    , 188 (1923).

    As a party to this proceeding, Henrico County presented its arguments to the Commission
    by filing briefs in connection with this case. The County was afforded an opportunity to be
    heard. Under the procedural due process standard set to the Commission, that is sufficient. See
    Taylor, 34 Va. App. at 243 (“Even though workers’ compensation proceedings may be more
    informal than judicial proceedings, “the [C]ommission must use procedures that ‘afford the
    parties minimal due process safeguards.’” (quoting WLR Foods, Inc. v. Cardosa, 
    26 Va. App. 220
    , 243 (1997))).
    III. The Commission did not err in finding that the accident caused O’Neil’s injuries.
    We “consider[] the evidence in the light most favorable to the prevailing party.”
    Smith-Adams v. Fairfax Cnty. Sch. Bd., 
    67 Va. App. 584
    , 590 (2017). “Factual findings of the
    [C]ommission will not be disturbed on appeal unless plainly wrong or without credible evidence
    to support them.” 
    Id.
     (quoting Ga. Pac. Corp. v. Dancy, 
    17 Va. App. 128
    , 135 (1993)). “In
    determining whether credible evidence exists, the appellate court does not retry the facts,
    reweigh the preponderance of the evidence, or make its own determination of the credibility of
    the witnesses.” 
    Id.
     (quoting Wagner Enters., Inc. v. Brooks, 
    12 Va. App. 890
    , 894 (1991)). “If
    there is evidence, or reasonable inferences can be drawn from the evidence, to support the
    [C]ommission’s findings, they will not be disturbed on review.” 
    Id.
    Henrico County asserts that the Commission could not have found that the claimant’s
    injuries were causally related to the workplace accident because a medical expert did not
    affirmatively find causation. But the Commission is not required to rely exclusively on an expert
    finding of causation. Instead, “where ‘the [medical] reports reflect only the results of claimant’s
    physical examination and do not purport to establish the cause or causes of her injury[,] . . . the
    [C]ommission [is] free to credit claimant’s testimony at the hearing as a basis for its finding of
    - 15 -
    causation.’”8 See Strictly Stumps, Inc. v. Enoch, 
    33 Va. App. 792
    , 795 (2000) (quoting Dollar
    Gen. Store v. Cridlin, 
    22 Va. App. 171
    , 177 (1996)).
    In Enoch, the claimant testified that he was injured when a tree fell on his right foot on
    September 1, 1997, and that he experienced intermittent pain in the foot before seeking treatment
    about a year later, on August 30, 1998. Id. at 794. A witness for the employer remembered that
    a tree fell on the claimant in “early September 1997,” and that the claimant said his foot hurt
    after the tree fell on it. Id. Another witness saw the tree fall but testified that it fell on the
    claimant’s left foot. Id. The written materials from the claimant’s healthcare providers noted the
    incident from 1997 and provided no alternative theories of causation. Id. at 796. The Court
    found that this evidence was sufficient to prove that the fallen tree caused the foot injury. Id.
    Here, O’Neil’s testimony establishes that her pain began after the lieutenant punched her
    in the neck. After the punch, she experienced pain in her jaw, left arm, collarbone, and neck.
    There is a logical causal relationship between a punch in the neck and immediate pain in the
    neck and surrounding body area. Multiple reports from various doctors reference the workplace
    incident and do not provide alternative theories of causation. O’Neil did not testify regarding
    any intervening causes or complications, such as a prior or subsequent injury history. The set of
    facts is strikingly similar to the evidence that we deemed sufficient to prove causation in Enoch.
    See id. at 794. Under these circumstances, the causal link was not only logical, but it was also
    obvious. Thus, the Commission was free to credit O’Neil’s testimony that the workplace
    8
    Henrico County argues that Enoch requires medical experts to establish causation where
    a medical diagnosis is complex. That argument mischaracterizes Enoch, which held that medical
    experts must establish causation when medical causation is complex. See Enoch, 33 Va. App. at
    796. Although Enoch states that “[t]he record in this case does not establish that the medical
    issue was so complex that the [C]ommission made findings in an area that could only be properly
    decided by medical experts,” the context of the opinion makes it clear that medical experts must
    establish causation only where the issue of causation is medically complex. See id.

    accident caused her injuries. The Commission’s finding was supported by credible evidence,
    and we will not disturb it on appeal.
    CONCLUSION
    Based on the foregoing reasons, we affirm the judgment of the Workers’ Compensation
    Commission.
    Affirmed.
