    RECKTENWALD, C.J., NAKAYAMA, McKENNA, POLLACK, AND WILSON, JJ.
    OPINION OF THE COURT BY WILSON, J.
    In this case we consider the issue first addressed in
    Nordic PCL Constr., Inc. v. LPIHGC, LLC, 136 Hawaiʻi 29, 358 P.3d
    ____*** FOR PUBLICATION IN WEST’S HAWAIʻI REPORTS AND PACIFIC REPORTER ***____
    1 (2015), of whether under the Hawaiʻi Uniform Arbitration Act
    (HUAA) (codified at Hawaiʻi Revised Statutes (HRS) chapter 658A),
    a decision of a neutral arbitrator must be vacated due to
    evident partiality.
    The case arises from the arbitration of a construction
    contract dispute between homeowners Ramon Romero and Cassie
    Romero (the Romeros) and contractor Noel Madamba Contracting LLC
    (Madamba).    The main question before us is whether arbitrator
    Patrick K.S.L. Yim’s (Yim) failure to disclose his possible
    attorney-client relationship with the Romeros’ counsel’s law
    firm constituted evident partiality requiring vacatur of the
    arbitration award by the circuit court.
    Following Yim’s issuance of a partial final
    arbitration award, the parties learned that Cades Schutte LLP
    (Cades)—the law firm representing the Romeros throughout the
    arbitration—had been retained by the administrator of Yim’s
    personal retirement accounts to ensure that the accounts
    complied with state and federal laws.          Based on this previously
    undisclosed information, Madamba moved to vacate the arbitration
    award.   The Circuit Court of the First Circuit (circuit court)
    denied Madamba’s motion to vacate, determining that Yim’s
    failure to disclose did not constitute evident partiality.              The
    Intermediate Court of Appeals (ICA) affirmed.
    2
    ____*** FOR PUBLICATION IN WEST’S HAWAIʻI REPORTS AND PACIFIC REPORTER ***____
    We hold that Yim’s failure to disclose his
    relationship with Cades created a reasonable impression of
    partiality, and as such, resulted in a violation of the
    disclosure requirements enumerated in HRS § 658A-12.             As we
    recently held in Nordic, for neutral arbitrators, a violation of
    the disclosure statutes results in evident partiality as a
    matter of law.     136 Hawaiʻi at 
    50, 358 P.3d at 22
    .         Thus, the
    circuit court’s determination that there was no showing of
    evident partiality was clearly erroneous.          We also clarify
    Nordic and hold that pursuant to the plain language of HRS
    § 658A-23(a)(2)(A), where there is evident partiality on the
    part of a neutral arbitrator, the award shall be vacated.
    Accordingly, we vacate the ICA and the circuit court’s judgments
    and remand to the circuit court with instructions to vacate the
    arbitration award.
    I.    Background
    A.    Arbitration Proceedings
    On June 1, 2009, the Romeros and Madamba entered into
    a contract in which the Romeros agreed to pay $425,000 for
    Madamba to complete a new construction for a two-story home in
    Honolulu, Hawaii.     Over a year later, in November 2010, Keith Y.
    Yamada (Yamada), an attorney from the law firm Cades, sent a
    3
    ____*** FOR PUBLICATION IN WEST’S HAWAIʻI REPORTS AND PACIFIC REPORTER ***____
    demand letter to Madamba and A&B Green Building LLC (A&B)1
    notifying them that Cades had been retained by the Romeros and
    that legal action would be taken against them for breach of
    contract as the project had been abandoned.
    On February 28, 2011, the Romeros filed a demand for
    arbitration against Madamba and A&B alleging seven separate
    counts, including breach of contract.2         The demand was submitted
    to Dispute Prevention & Resolution, Inc. (DPR).            The Romeros
    continued to be represented by Yamada of Cades along with Andrew
    L. Salenger, also of Cades.        The parties provided ranked lists
    of proposed third-party neutrals to DPR and based on the lists
    received, Yim was appointed as arbitrator on May 31, 2011.               On
    June 1, 2011, Yim provided his disclosures through DPR Case
    Manager Kelly Bryant (Bryant).        The disclosures noted, inter
    alia, that while Yim was a judge,3 “counsel and members of their
    firms appeared before [him]” and that “[s]ince retirement, [he
    1
    A&B was hired by the Romeros to provide design services in
    relation to the project. A&B did not participate in the arbitration at
    issue.
    2
    Both the agreement between the Romeros and Madamaba and the
    agreement between the Romeros and A&B provided for arbitration for disputes.
    The agreement with Madamaba noted that disputes should first be submitted to
    the architect in charge of the project prior to submitting them to
    arbitration. In their demand for arbitration, the Romeros stated that the
    agreement provided “that disputes may first be submitted to [the architect]
    for decision before being referred to arbitration,” but noted that “in light
    of the number and pervasiveness of the disputes herein,” referring the matter
    to the architect would not “assist in reaching a resolution.”
    3
    Yim is a former judge of the Circuit Court of the First Circuit.
    4
    ____*** FOR PUBLICATION IN WEST’S HAWAIʻI REPORTS AND PACIFIC REPORTER ***____
    had] served as a [n]eutral for counsel and members of their
    firms.”   Yim made no disclosures regarding his relationship with
    Cades in connection with his personal retirement accounts.
    The arbitration hearings took place on November 2-4,
    2011.   On January 26, 2012, Yim issued his Partial Final Award
    of Arbitrator (Partial Final Award).         Yim concluded that Madamba
    breached the construction contract and that the Romeros were
    entitled to recover $154,476.51 in compensatory damages.             Yim
    retained jurisdiction to address attorneys’ fees and costs.
    In February and March 2012, following the issuance of
    the Partial Final Award, Yim made three supplemental disclosures
    to the parties regarding his relationship with Cades in
    connection with his personal retirement accounts.            All three
    supplemental disclosures were transmitted to party counsel by
    Bryant via email.
    Bryant sent the first supplemental disclosure to party
    counsel on February 22, 2012, almost a month after Yim issued
    his Partial Final Award.       The disclosure informed the parties
    that Cades had been recently retained by the administrator of
    Yim’s personal retirement accounts to handle compliance
    documentation related to his accounts.          The disclosure stated
    that Yim hired Pension Services Corporation (PSC) in the 1990s
    to manage his personal retirement accounts and PSC’s role
    5
    ____*** FOR PUBLICATION IN WEST’S HAWAIʻI REPORTS AND PACIFIC REPORTER ***____
    included ensuring that Yim’s accounts were “compliant with all
    state and federal laws.”       PSC hired Cades to assist in the legal
    review of Yim’s accounts and according to the disclosure, Yim’s
    role in Cades’s retention was limited:
    Recently, PSC retained two law firms in Honolulu to handle
    their clients’ compliance documentation. Judge Yim’s
    account was in the group given to Cades Schutte.
    Please note that Judge Yim is PSC’s client, Judge Yim did
    not select or retain Cades Schutte personally, and he had
    no input as to who PSC selected. The Judge was advised
    that his accounts were given to Cades after the fact.
    Judge Yim will sign documents drafted by Cades, and Cades
    will invoice Judge Yim directly for any compliance work
    done on his account.
    Bryant’s email also noted that Yim “[did] not feel this
    disclosure will in any way affect his ability to serve in a
    neutral and unbiased manner, but felt it was best to disclose
    this newly discovered information.”         DPR requested that any
    comments regarding the disclosure be filed in writing by
    February 24, 2012.
    On February 24, 2012, Madamba objected to Yim serving
    as arbitrator based on the supplemental disclosure, and
    requested more information regarding Yim’s relationship with
    Cades.   The Romeros also responded to the disclosure.
    Specifically, the Romeros’ counsel, Yamada, stated that he
    confirmed with the firm’s pension benefits counsel, Ellen
    Kawashima (Kawashima), that Cades had done “no work for PSC on
    Judge Yim’s account and will not do so if at all until the
    6
    ____*** FOR PUBLICATION IN WEST’S HAWAIʻI REPORTS AND PACIFIC REPORTER ***____
    completion of the Romero arbitration.”          Yamada further noted
    that “[t]here is no existing relationship that is in place and
    no engagement letter signed.”        Yamada also stated that he
    personally had no knowledge of the “proposed relationship” prior
    to Yim’s disclosure and stated that “[a]ll rulings prior to
    February 24th must remain undisturbed because no one (neither
    Judge Yim nor Cades Schutte) could have foreseen during the
    Madamba arbitration that this relationship might develop.”
    On February 29, 2012, Bryant provided a second
    supplemental disclosure regarding Yim’s relationship with Cades.
    Bryant stated that Yim first spoke with Kawashima “a day or a
    couple days before this most recent disclosure was sent out”4 and
    that “[h]e instructed [Kawashima] to run a conflict check
    through her firm.”      Bryant also stated that Cades had not
    provided Yim with any services nor had Yim signed an engagement
    letter with Cades or paid any fees to Cades.           Finally, the
    disclosure noted that Yim had instructed PSC to withdraw his
    file from Cades and send the work to another law firm.             DPR
    requested any comments before March 2, 2012.           In response,
    Madamba’s counsel requested additional information and
    clarification regarding the disclosures.
    4
    In the third supplemental disclosure it was clarified that “this
    most recent disclosure” referred to the February 22, 2012 first supplemental
    disclosure.
    7
    ____*** FOR PUBLICATION IN WEST’S HAWAIʻI REPORTS AND PACIFIC REPORTER ***____
    The third and final supplemental disclosure, emailed
    to party counsel on March 5, 2012, provided additional details
    about Yim’s relationship with Cades.         The disclosure stated that
    “Yim advised DPR that Nobuo Kiwada [(Kiwada)] handles his
    account at [PSC]” and that Kiwada could provide an “accurate
    timeline” of the relevant events.         According to the disclosure,
    Kiwada first raised the possibility of Cades’s review of Yim’s
    retirement accounts with Yim in May 2011—the month Yim was
    confirmed by the parties as a neutral arbitrator—and Yim
    deferred to Kiwada as to which firm would be involved:
    In May 2011, Mr. Kiwada advised Judge Yim that certain
    amendments would need to be done to all pension documents
    to comply with all new state and federal laws. Mr. Kiwada
    was considering various attorneys of which Roger Fonseca
    [of Cades] was one. Judge Yim advised Mr. Kiwada that he
    would defer to Mr. Kiwada’s judgment as to who to send his
    file to, and Judge Yim was not involved in PSC’s decision
    as to which law firms would be selected.
    According to the disclosure, “[n]othing further was done on this
    issue until December 30, 2011 when PSC sent a letter to all
    their clients advising them that their files would be sent to a
    law firm (no law firm was named in the letter) to handle
    [certain statutory] requirements.”
    The disclosure further noted that Cades’s involvement
    became more definite several months later when Kiwada informed
    Yim that his accounts would likely be reviewed by Cades: “On
    8
    ____*** FOR PUBLICATION IN WEST’S HAWAIʻI REPORTS AND PACIFIC REPORTER ***____
    January 30, 2011,[5] Mr. Kiwada advised Judge Yim that his file
    would be sent to a law firm, probably Cades.”           At this point,
    Yim again “advised Mr. Kiwada that he would leave it up to Mr.
    Kiwada to determine which law firm would receive his file.”
    Regarding Yim’s contact with Cades in relation to his retirement
    accounts, the disclosure stated: “Judge Yim first spoke with
    Ellen Kawashima at the Cades firm one or two days days [sic]
    prior to his February 22, 2012 disclosure.           Until his
    conversation with Ellen, he did not know his file was with
    Cades.”   Finally, the disclosure stated that Bryant confirmed
    with Kiwada that Yim’s file had “been reassigned to another law
    firm.”
    Madamba responded to the third disclosure, requesting
    additional information related to the communications between Yim
    and Kiwada that occurred in May 2011.          Madamba also argued that
    the Partial Final Award should be vacated due to Yim’s
    violations of the disclosure rules.         Despite Madamba’s
    objections and its request for additional discovery, DPR
    affirmed Yim’s role as arbitrator and informed the parties that
    Yim would issue a final arbitration award.6
    5
    Kiwada later testified that the meeting at issue took place on
    January 20, 2012 and not in 2011.
    6
    Madamba’s counsel notified DPR that Madamba had filed a Motion to
    Vacate the Partial Final Award along with a Motion to Stay Arbitration
    (continued . . .)
    9
    ____*** FOR PUBLICATION IN WEST’S HAWAIʻI REPORTS AND PACIFIC REPORTER ***____
    On April 25, 2012, Yim issued the Final Award of
    Arbitration (Final Award), which incorporated the Partial Final
    Award and awarded the Romeros approximately $42,000 in
    attorneys’ fees, based on work performed by Cades.
    B.    Circuit Court Proceedings
    Following Yim’s supplemental disclosures, Madamba
    filed pleadings in the circuit court to disqualify Yim, stay the
    arbitration proceeding, and vacate the Partial Final Award.
    However, prior to the circuit court’s hearing on Madamba’s
    motion to vacate the Partial Final Award, Yim issued the Final
    Award.
    Accordingly, after Yim issued the Final Award, Madamba
    filed a Motion to Vacate Final Award, arguing, inter alia, that
    Yim failed to disclose his relationship with Cades and that
    “there was evident partiality of the [a]rbitrator.”            In support,
    Madamba cited several provisions of HRS chapter 658A7 as well as
    DPR Rule 9, which required that arbitrators disclose “any past,
    present, or possible future relationship with the parties, their
    ( . . . continued)
    Proceedings and Disqualify Yim in the circuit court and that the arbitration
    should be stayed pending the resolution of the motions. DPR responded that
    since there was no court order to stay arbitration and no mutual agreement
    between the parties, Yim would proceed to issue a final award.
    7
    Pursuant to HRS § 658A-3(c) (Supp. 2001), “[a]fter June 30, 2004,
    [chapter 658A] governs an agreement to arbitrate whenever made.”
    10
    ____*** FOR PUBLICATION IN WEST’S HAWAIʻI REPORTS AND PACIFIC REPORTER ***____
    witnesses, their counsel or another arbitrator including any
    bias or any financial or personal interest in the result of the
    arbitration.”     The Romeros filed a Motion to Confirm Final
    Award.
    Madamba also requested additional discovery related to
    Yim’s relationship with Cades.        Specifically, Madamba subpoenaed
    and, as a result, received records from DPR.8           Madamba also
    deposed three PSC employees:        Kiwada, the president of PSC;
    Julie Kiwada (Julie), Kiwada’s daughter who was being trained as
    a consultant at PSC; and Bruce Lee (Lee), a pension consultant.
    Madamba also deposed Kawashima, the Cades pension benefits
    attorney who had been mentioned in the disclosures.9
    Kiwada’s deposition testimony confirmed that Kiwada
    met with Yim in May 2011—more than seven months before Yim
    issued the January 26, 2012 Partial Final Award—and advised Yim
    that PSC would be negotiating with Cades and the law firm
    Carlsmith Ball LLP (Carlsmith) to potentially handle compliance
    work related to his retirement accounts.          Kiwada also testified
    8
    Madamba filed a motion to compel production of the DPR files, and
    DPR objected on the grounds that HRS § 658A-14(d) “preclude[d] the production
    of documents by DPR or any arbitration association unless you can show
    basically a prima facie ground to vacate the award.” The circuit court
    disagreed with DPR, stating that a prima facie showing had been made and
    ordered DPR to produce certain records from the arbitration.
    9
    Kawashima’s deposition transcript was not included in the record
    on appeal and, thus, was not considered by this court.
    11
    ____*** FOR PUBLICATION IN WEST’S HAWAIʻI REPORTS AND PACIFIC REPORTER ***____
    that he informed Yim he would eventually recommend one of the
    two firms to represent him.       The DPR documents revealed that the
    next month, in June 2011, PSC sent an email to Kawashima at
    Cades providing the names of several clients, including Yim, so
    that Cades could research potential conflicts of interest.
    Kawashima responded to PSC, stating that that there was no
    conflict between Cades and Yim.
    Approximately six months later, in December 2011, PSC
    sent a letter to Yim stating that it “had made arrangements with
    two [Employee Retirement Income Security Act (ERISA)] law firms
    in Honolulu” to complete work related to his pension plan.
    Specifically, the law firms would be ensuring that Yim’s plans
    complied with the requirements of the Economic Growth & Tax
    Relief Reconciliation Act prior to submission to the Internal
    Revenue Service.     The letter noted that the fee charged by the
    law firm would be “approximately $2,500.”
    Both Kiwada and Julie also testified that they met
    with Yim in January 2012 regarding his retirement plan.             Kiwada
    and Julie stated that this meeting occurred on January 20, 2012.
    The meeting date was corroborated by handwritten notes taken by
    Julie.   Their testimony that the meeting date was January 20th—
    six days before Yim issued the Partial Final Award—did not match
    the date in Yim’s third supplemental disclosure, which stated
    12
    ____*** FOR PUBLICATION IN WEST’S HAWAIʻI REPORTS AND PACIFIC REPORTER ***____
    that Yim and Kiwada met on January 30th.         Yim’s disclosure stated
    that, “Kiwada advised Judge Yim that his file would be sent to a
    law firm, probably Cades.”       However, Kiwada did not remember
    whether he had specifically mentioned Cades during the meeting,
    and Julie testified that she thought “[they] did talk about it”
    but could not “recall the details.”
    Four days following the meeting, on January 24, 2012—
    and two days before issuance of the January 26, 2012 Partial
    Final Award—Julie emailed documents related to Yim’s retirement
    plan to Kawashima at Cades.        The transmittal email noted: “We
    spoke to the client and he knows the fee and that your
    engagement letter should be coming soon.”
    Following transmission of the files to Cades, it
    appears that Yim, PSC, and Kawashima discussed the issue of a
    potential conflict between Cades and Yim.          A February 15, 2012
    internal PSC email from Kiwada to Julie, Lee, and others states:
    “Pat Yim will resolve his situation directly with Cades.             Ellen
    [Kawashima] will get back to us in a couple of days if Cades can
    still represent Pat Yim.”       On February 21, 2012, Yim sent an
    email to Bryant at DPR explaining the situation with PSC and
    Cades and stating that Kiwada “made the decision to refer [his]
    compliance work with a group of his clients to the Cades firm.”
    Yim stated that he would be billed directly by Cades for the
    13
    ____*** FOR PUBLICATION IN WEST’S HAWAIʻI REPORTS AND PACIFIC REPORTER ***____
    “work performed” but that other than providing signatures as
    necessary he did “not expect[] to interact with the firm.”              The
    first supplemental disclosure was sent to the parties the
    following day.     Thus, when Yim sent this supplemental disclosure
    on February 22, 2012, he was aware Cades would be acting as his
    personal attorney.
    On June 12, 2012, Madamba filed a motion to continue
    the hearing on the Motion to Vacate Final Award and Motion to
    Confirm Final Award which had been set for June 19, 2012.
    Madamba stated that it needed additional time to conduct
    discovery on the disclosure issue, including taking the
    depositions of Yim and Bryant.10        The circuit court granted
    Madamba a continuance to introduce evidence in support of its
    Motion to Vacate Final Award.
    On June 18, 2012, Madamba noticed Yim’s deposition as
    well as the depositions of Bryant and DPR’s Chief Executive
    Officer, Keith Hunter (Hunter).        DPR’s counsel filed a motion
    for a protective order, stating that Yim and the DPR employees
    were immune from testifying pursuant to HRS § 658A-14(d)(2).11
    10
    In the motion, Madamba also argued that it had the right to a
    jury trial on the disclosure issue. The circuit court denied Madamba’s
    request for a jury trial but discussed Madamba’s right to an evidentiary
    hearing. The court determined, however, that because Madamba had failed to
    make a prima facie showing of evident partiality, an evidentiary hearing was
    not warranted. This issue was not raised on certiorari.
    11
    HRS § 658A-14(d)(2) (Supp. 2001) provides:
    (continued . . .)
    14
    ____*** FOR PUBLICATION IN WEST’S HAWAIʻI REPORTS AND PACIFIC REPORTER ***____
    The motion for protective order was set for hearing on August 1,
    2012, the same date the circuit court had scheduled to hear the
    Romeros’ Motion to Confirm and Madamba’s Motion to Vacate.
    Madamba filed an ex parte motion to shorten time on the motion
    for protective order, claiming there were numerous disputed
    issues of facts which required further discovery from Bryant,
    Hunter, and Yim.        The motion to shorten time was denied by the
    circuit court on July 2, 2012.
    Madamba then filed a memorandum in support of its
    motion to vacate, arguing, inter alia, that Yim breached his
    duty to disclose under the DPR rules and HRS § 658A-12(a), which
    requires an arbitrator to disclose “any known facts that a
    ( . . . continued)
    Immunity of arbitrator; competency to testify;
    attorney’s fees and costs.
    . . . .
    (d) In a judicial, administrative, or similar
    proceeding, an arbitrator or representative of
    an arbitration organization is not competent to
    testify, and shall not be required to produce
    records as to any statement, conduct, decision,
    or ruling occurring during the arbitration
    proceeding, to the same extent as a judge of a
    court of this State acting in a judicial
    capacity. This subsection does not apply:
    . . . .
    (2) To a hearing on a motion to vacate an award
    under section 658A-23(a)(1) or (2) if the
    movant establishes prima facie that a ground
    for vacating the award exists.
    15
    ____*** FOR PUBLICATION IN WEST’S HAWAIʻI REPORTS AND PACIFIC REPORTER ***____
    reasonable person would consider likely to affect the
    impartiality of the arbitrator in the arbitration proceeding.”
    On this basis, Madamba maintained that Yim’s failure to disclose
    resulted in evident partiality and that accordingly, the
    arbitration award should be vacated.         The Romeros filed a
    response to Madamba’s motion, arguing that Madamba failed to
    meets its burden in demonstrating evident partiality.
    The circuit court heard the Motion to Vacate Final
    Award, Motion to Confirm Final Award, and DPR’s motion for a
    protective order on August 1, 2012.12         After hearing from the
    parties, the circuit court orally denied Madamba’s Motion to
    Vacate and granted the Romeros’ Motion to Confirm Final Award,
    explaining its reasoning on the record.          The court determined
    that the relationship between Yim and Cades was a “possible
    future relationship” and thus DPR Rule 9 had been violated.
    However, the court indicated that there was no violation of HRS
    § 658A-12 citing to the language in HRS § 658A-12(a)(2), which
    specifically refers to disclosures of “existing or past
    relationship[s].”     In this respect, the court stated:
    What we have here, we have a particular situation which,
    under the DPR, Rule 9 speaks to a possible future
    relationship and a disclosure. There is no dispute that
    under 658A-12, it speaks to existing or past relationship.
    Now, both parties had agreed to be bound by the DPR rules
    regarding whatever rules DPR sets forth which includes
    disclosure of a possible -- possible -- future

    relationship. What we have here is the existence of a
    possible future relationship.
    The court next considered whether there was evident
    partiality pursuant to HRS § 658A-23.           First, the court
    reiterated that the relationship between Cades and Yim “was a
    potential” or “possible” future relationship that was never
    “formulated,” whereas relevant caselaw finding evident
    partiality for a failure to disclose considered “prior” or
    “current” relationships.       The court additionally addressed
    Madamba’s claim that “particular instances” in the record
    demonstrated evident partiality.           In this regard, the court
    determined Madamba failed to demonstrate evident partiality.
    Accordingly, the court denied Madamba’s motion to vacate and
    granted the Romeros’ motion to confirm.
    The circuit court additionally determined that DPR’s
    motion for protective order was moot, given its confirmation of
    the Final Award.
    C.    ICA Appeal
    Madamba raised several issues before the ICA.           Of
    relevance on certiorari, Madamba argued that the circuit court’s
    finding that Yim failed to disclose his relationship with Cades
    in violation of DRP Rule 9—in and of itself—required the
    circuit court to vacate the award.           Further, Madamba contended
    that Yim violated his duty to disclose under HRS § 658A-12(a),
    17
    ____*** FOR PUBLICATION IN WEST’S HAWAIʻI REPORTS AND PACIFIC REPORTER ***____
    which he claimed encompasses a requirement to disclose potential
    future relationships that “a reasonable person would consider
    likely to affect the impartiality of the arbitrator in the
    arbitration proceeding.” (Quoting HRS § 658A-12(a)).             Madamba
    additionally argued that the circuit court erred in refusing to
    allow additional discovery, including the depositions of Bryant,
    Hunter, and Yim.
    In response, the Romeros argued that the circuit court
    properly denied Madamba’s motion to vacate because Madamba
    failed to demonstrate evident partiality.          In this regard, the
    Romeros claimed that a nondisclosure does not alone constitute
    evident partiality and that the potential relationship between
    Cades and Yim, which was never consummated, did not create the
    impression of bias warranting vacatur.          Regarding the
    depositions of Bryant, Hunter, and Yim, the Romeros argued that
    the reason the depositions were never taken was that Madamba
    delayed in scheduling them.        The Romeros further contended that
    there were no additional facts to be gained through these
    depositions.
    In its Summary Disposition Order, the ICA rejected
    Madamba’s argument that Yim’s failure to disclose required the
    circuit court to vacate the arbitration award.           Noel Madamba

    ____*** FOR PUBLICATION IN WEST’S HAWAIʻI REPORTS AND PACIFIC REPORTER ***____
    at *3 (App. May 23, 2014) (SDO).           The ICA concluded that
    although Yim violated the DPR rules because he failed to
    disclose a possible future relationship with Cades, he was “not
    necessarily in violation of HRS § 658A-12(a)(2),” which only
    applies to disclosure of “past or present relationships.”               
    Id. Turning to
    the question of whether the failure to disclose
    resulted in evident partiality, the ICA determined that it did
    not because the relationship between Yim and Cades “remained
    inchoate during the pendency of arbitration”; “was anticipated
    to be minimal at best”; and “lacked the significance, actuality,
    and contemporaneous nature” discussed in the relevant case law.
    
    Id. at *3-4.
    The ICA also found no error in the circuit court’s
    decision to rule on Madamba’s motion to vacate prior to the
    depositions of Yim and the other DPR personnel.            
    Id. at *4.
        In
    this regard, the ICA held that a prima facie case for vacating
    the award did not exist, and thus, the depositions were barred
    pursuant to HRS § 658A-14(d)(2), which provides immunity for
    arbitrators and representatives of arbitration organizations.

    that Yim’s Failure To Disclose Did Not Result in
    Evident Partiality
    21
    ____*** FOR PUBLICATION IN WEST’S HAWAIʻI REPORTS AND PACIFIC REPORTER ***____
    In Nordic, we laid out the legal framework relevant to
    an arbitrator’s failure to disclose under HRS chapter 658A.
    Specifically, as acknowledged in Nordic, 136 Hawaiʻi at 
    44-45, 358 P.3d at 16-17
    , pursuant to the disclosure requirements
    enumerated in HRS § 658A-12, prior to accepting appointment and
    “after making a reasonable inquiry,” arbitrators are required to
    “disclose to all parties . . . any known facts that a reasonable
    person would consider likely to affect the impartiality of the
    arbitrator[.]”     HRS § 658A-12(a).       Arbitrators also have a
    “continuing obligation to disclose . . . any facts . . .
    learn[ed] after accepting appointment which a reasonable person
    would consider likely to affect the impartiality of the
    arbitrator.”     HRS § 658A-12(b).13       If an arbitrator discloses
    13
    In full, HRS § 658A-12(a)-(b) (Supp. 2001) states:
    (a) Before accepting appointment, an individual
    who is requested to serve as an arbitrator,
    after making a reasonable inquiry, shall
    disclose to all parties to the agreement to
    arbitrate and arbitration proceeding and to any
    other arbitrators any known facts that a
    reasonable person would consider likely to
    affect the impartiality of the arbitrator in
    the arbitration proceeding, including:
    (1) A financial or personal interest in the
    outcome of the arbitration proceeding; and
    (2) An existing or past relationship with any
    of the parties to the agreement to arbitrate or
    the arbitration proceeding, their counsel or
    representatives, a witness, or another
    arbitrator.
    (b) An arbitrator has a continuing obligation
    (continued . . .)
    22
    ____*** FOR PUBLICATION IN WEST’S HAWAIʻI REPORTS AND PACIFIC REPORTER ***____
    facts that a reasonable person would consider likely to affect
    the impartiality of the arbitrator in the arbitration proceeding
    pursuant to HRS § 658A-12(a) or (b) “and a party timely objects
    to the appointment or continued service of the arbitrator based
    upon the fact disclosed, the objection may be a ground under
    section 658A-23(a)(2) for vacating” the award.              HRS § 658A-12(c)
    (Supp. 2001).        Similarly, if an arbitrator does not disclose a
    fact required to be disclosed under HRS § 658A-12(a) or (b),
    “upon timely objection by a party, the court under section 658A-
    23(a)(2) may vacate an award.”           HRS § 658A-12(d) (Supp. 2001).
    In turn, HRS § 658A-23(a)(2) provides that the court “shall
    vacate an award made in the arbitration proceeding” upon a
    motion by a party to the proceeding if, inter alia, there was
    “[e]vident partiality by an arbitrator appointed as a neutral
    arbitrator.”14
    ( . . . continued)
    to disclose to all parties to the agreement to
    arbitrate and arbitration proceeding and to any
    other arbitrators any facts that the arbitrator
    learns after accepting appointment which a
    reasonable person would consider likely to
    affect the impartiality of the arbitrator.

    Our court first established an evident partiality
    standard for cases involving an arbitrator’s failure to disclose
    in Daiichi Hawaii Real Estate Corp. v. Lichter, where we
    acknowledged that “[w]hat constitutes ‘evident partiality’
    sufficient to vacate an arbitration award is a difficult
    question.”    103 Hawaii at 
    339, 82 P.3d at 425
    (quoting Valrose
    Maui, Inc. v. Maclyn Morris, Inc., 
    105 F. Supp. 2d 1118
    , 1124
    (D. Haw. 2000)).        In Daiichi, we considered the circuit court’s
    granting of a motion to vacate an arbitration award pursuant to
    HRS § 658-9(2), which has since been repealed.              
    Id. at 327-28,
    82 P.3d at 413-14.         Under HRS § 658-9(2) (1993), a court could
    vacate an arbitration award “upon the application of any party
    to the arbitration . . . [w]here there was evident partiality
    . . . in the arbitrators.”            We held that evident partiality is
    “present when undisclosed facts show ‘a reasonable impression of
    partiality.’”        Daiichi, 103 Hawaiʻi at 
    339, 82 P.3d at 425
    ( . . . continued)
    . . . .
    (2) There was:
    (A) Evident partiality by an arbitrator
    appointed as a neutral arbitrator;
    (B) Corruption by an arbitrator; or
    (C) Misconduct by an arbitrator prejudicing the
    rights of a party to the arbitration
    proceeding[.]

    (emphasis added) (quoting Schmitz v. Zilveti, 
    20 F.3d 1043
    , 1046
    (9th Cir. 1994)).     Under this analysis, a finding of evident
    partiality related to a failure to disclose is not dependent on
    a showing that the arbitrator was actually biased, but instead
    stems from the nondisclosure itself.         
    Id. at 352,
    82 P.3d at 438
    (citing 
    Schmitz, 20 F.3d at 1045
    ).         We further noted that the
    United States Supreme Court had “emphasized the manifest
    importance of a neutral arbitrator disclosing ‘to the parties
    any dealings that might create an impression of possible bias,’”
    
    id. at 341,
    82 P.3d at 427 (quoting Commonwealth Coatings Corp.
    v. Cont’l Cas. Co., 
    393 U.S. 145
    , 149 (1968)), but also
    acknowledged that “not all dealings rise to the level of
    creating the impression—or reality—of possible bias so as to
    warrant” vacatur, 
    id. Finally, we
    stated that “[t]he burden of
    proving facts which would establish a reasonable impression of
    partiality rests squarely on the party challenging the award.”
    Id. at 
    339, 82 P.3d at 425
    (citation omitted) (internal
    quotation marks omitted).
    As 
    noted supra
    , we recently reiterated in Nordic, that
    evident partiality is established where “undisclosed facts
    demonstrate a reasonable impression of partiality.”            136 Hawaiʻi
    at 
    51, 358 P.3d at 23
    (quoting Daiichi, 103 Hawaii at 
    340, 82 P.3d at 426
    ) (internal quotation mark omitted).            We also, for
    25
    ____*** FOR PUBLICATION IN WEST’S HAWAIʻI REPORTS AND PACIFIC REPORTER ***____
    the first time, explained the relationship between the standards
    for disclosure established in HRS § 658A-12 and a finding of
    evident partiality.      In this respect, we determined that in the
    context of neutral arbitrators, “a failure to meet disclosure
    requirements under HRS § 658A-12(a) or (b) is equivalent to, or
    constitutes, ‘evident partiality’ as a matter of law.”             Id. at
    
    50, 358 P.3d at 22
    .      Thus, in Nordic, we interpreted the
    standard required for disclosure under § 658A-12(a) and (b),
    i.e, “facts a reasonable person would find likely to affect an
    arbitrator’s impartiality,” as equivalent to the Daiichi evident
    partiality standard previously adopted by our court, i.e.,
    undisclosed facts demonstrating a reasonable impression of
    impartiality.15
    15
    Our standard for evident partiality as well as that of the Ninth
    Circuit (and some other federal and state courts), requires only a
    “reasonable impression of partiality,” and as such, is more expansive than
    the standard proposed by a majority of federal circuit courts of appeal,
    which limit findings of evident partiality to situations “where a reasonable
    person would have to conclude that an arbitrator was partial to one party to
    the arbitration.” Andersons, Inc. v. Horton Farms, Inc., 
    166 F.3d 308

    2013) (“The requirement that this Court must perceive partiality so clearly
    that it ‘would have to conclude’ the arbitrator was biased before vacating

    looks only for ‘an impression of possible bias.’”), aff’d, 549 F. App’x 41

    26
    ____*** FOR PUBLICATION IN WEST’S HAWAIʻI REPORTS AND PACIFIC REPORTER ***____
    Under this framework, we now consider whether Yim’s
    failure to disclose his relationship with Cades resulted in a
    violation of HRS § 658A-12(a) or (b), or stated otherwise,
    whether the failure to disclose resulted in evident partiality,
    defined in our jurisdiction as a reasonable impression of
    partiality.    In considering this question, we recognize that
    judicial review of arbitration awards is limited.            Daiichi, 103
    Hawaiʻi at 
    339, 82 P.3d at 422
    .        However, because review of an
    arbitration award is limited, an arbitrator’s impartiality and
    appearance of impartiality is paramount.          As a corollary, the
    ( . . . continued)
    Indeed, in the federal courts, there is an “absence of a
    consensus on the meaning of ‘evident partiality.’” Montez v. Prudential
    Sec., Inc., 
    260 F.3d 980
    , 983 (8th Cir. 2001). The confusion stems from the
    United States Supreme Court’s decision in Commonwealth Coatings. In
    Commonwealth Coatings, Justice Black, writing for at least four justices of
    the Court, held that an arbitrator’s failure to “disclose to the parties any
    dealings that might create an impression of possible bias” was sufficient to
    support 
    vacatur. 393 U.S. at 147-49
    . Accordingly, the court vacated an
    award where a neutral arbitrator of a three-arbitrator panel failed to
    disclose his ongoing business relationship with one of the parties. 
    Id. at 146-47.
                Justice White joined the majority opinion but concurred
    separately, adopting a narrower view of the standard. Justice White noted
    that arbitrators should not be held to the same standards as judges, 
    id. at 150
    (White, J., concurring), but found that “for present purposes” it was
    sufficient to “hold . . . that where the arbitrator has a substantial
    interest in a firm which has done more than trivial business with a party,
    that fact must be disclosed,” 
    id. at 151-52
    (White, J., concurring). Justice
    White’s concurrence has opened the door for many of the federal circuit
    courts of appeal—and some state courts—to adopt a more stringent definition
    of evident partiality, requiring a showing beyond “an impression of possible
    bias.” Our court’s approach follows Justice Black’s reasoning.
    27
    ____*** FOR PUBLICATION IN WEST’S HAWAIʻI REPORTS AND PACIFIC REPORTER ***____
    disclosure process is of utmost import.          The Daiichi court
    recognized as much, quoting the United States Supreme Court for
    the proposition that “we should, if anything, be even more
    scrupulous to safeguard the impartiality of arbitrators than
    judges, since the former have completely free rein to decide the
    law as well as the facts and are not subject to appellate
    review.”    Id. at 
    341, 82 P.3d at 427
    (quoting Commonwealth
    
    Coatings, 393 U.S. at 149
    ); see also Kay v. Kaiser Found. Health
    Plan, Inc., 119 Hawaiʻi 219, 229, 
    194 P.3d 1181
    , 1191 (App. 2008)
    (acknowledging that the “judiciary should play a minimal rule in
    reviewing impartiality” but noting that “the sine qua non for
    minimal review must be the arbitrator’s fidelity to the
    disclosure obligation”).       Based on these principles, we hold
    that Yim’s failure to disclose his relationship with Cades
    created a reasonable impression of partiality, and accordingly,
    the circuit court’s findings that there was no violation of
    Yim’s duty to disclose under HRS chapter 658A and no showing of
    evident partiality are clearly erroneous.16
    16
    In Nordic, we remanded the case for an evidentiary hearing
    because “the circuit court did not explain the basis of its rulings on the
    record or enter findings of fact or conclusions of law” and material facts
    were in dispute. 136 Hawaiʻi at 
    31, 358 P.3d at 3
    . Here, however, the
    material facts were undisputed and the circuit court explained its reasoning
    for determining there was no evident partiality, as 
    discussed supra
    and
    infra. Accordingly, we are able to review the circuit court’s findings.
    28
    ____*** FOR PUBLICATION IN WEST’S HAWAIʻI REPORTS AND PACIFIC REPORTER ***____
    The key facts in this case establish that Yim was in
    discussions concerning his representation by Cades during the
    arbitration proceedings.       In summary, in May 2011, Yim met with
    the administrator of his retirement plan, who informed him that
    either Cades or Carlsmith would eventually handle compliance
    work related to his personal retirement accounts.            Yim was
    appointed as arbitrator in the underlying contract dispute the
    same month, and in June 2011 made a disclosure to the parties
    regarding his relationship with both law firms, but did not
    disclose that Cades might be representing him in connection with
    his personal retirement accounts.          Approximately six months
    later, in December 2011, Yim received a letter from his
    retirement plan administrator, explaining that arrangements had
    been made with two local ERISA law firms to review documents
    related to his retirement accounts, for a fee of “approximately
    $2,500.”
    In January 2012, after the arbitration hearing, but
    while the arbitration was pending, PSC, the administrator of
    Yim’s retirement accounts, met with Yim and informed him that
    his files would probably be sent over to Cades.            Also at this
    time, PSC transmitted Yim’s files to Cades.           A few days after
    the files were transmitted, Yim issued his Partial Final Award
    on January 26, 2012.      Yim made no disclosure regarding his
    29
    ____*** FOR PUBLICATION IN WEST’S HAWAIʻI REPORTS AND PACIFIC REPORTER ***____
    involvement with Cades until almost a month after issuing the
    Partial Final Award, when Yim learned that his file had been
    sent to Cades.     It was only when Madamba raised concerns
    regarding Cades’s representation of Yim, that Yim’s account was
    assigned to another law firm.        Yim continued to serve as the
    arbitrator and issued the Final Award over Madamba’s objections.
    Based on these facts, the circuit court determined
    that Yim’s failure to disclose his relationship with Cades
    resulted in a violation of DPR Rule 9 insofar as the rule
    requires the disclosure of certain possible future
    relationships.     Despite having found a violation of the DPR
    rule, and based, in part, on its description of the relationship
    between Yim and Cades as yet-to-be “formulated,” “potential,”
    “possible,” and “future,” the circuit court determined there was
    no evident partiality.17      In reaching this conclusion, the court
    stated, “[t]here is no dispute that under 658A-12[(a)(2)], it
    speaks to existing or past relationship[s]” as opposed to
    potential and future relationships.
    17
    As 
    discussed supra
    , the circuit court also appeared to consider
    evidence in the record of Yim’s actions during the arbitration that Madamba
    claimed demonstrated Yim was partial to the Romeros. Such a consideration
    might be appropriate to the extent Madamba raised an actual bias claim.
    However, we note that for claims of evident partiality based on a failure to
    disclose “an arbitrator’s nondisclosure of facts showing a potential conflict
    of interest creates evident partiality warranting vacatur even when no actual
    bias is present.” Daiichi, 103 Hawaii at 
    352, 82 P.3d at 438
    (quoting
    
    Schimitz, 20 F.3d at 1045
    ) (internal quotation marks omitted).
    30
    ____*** FOR PUBLICATION IN WEST’S HAWAIʻI REPORTS AND PACIFIC REPORTER ***____
    The ICA similarly determined that Yim violated the DPR
    rules, but stated that he did “not necessarily [violate] HRS
    § 658A-12(a)(2), as the latter expressly limits disclosure
    obligations to past or present relationships.”           Madamaba, SDO,
    
    2014 WL 2180001
    , at *3.       The ICA affirmed the circuit court on
    the basis that Yim’s failure to disclose did not amount to
    evident partiality because 1) his relationship with Cades was
    prospective in nature, and 2) the anticipated relationship would
    have been minimal and indirect.        
    Id. at *3-4.
    At the outset, we address the circuit court and the
    ICA’s conclusion in relation to the disclosure requirements in
    HRS § 658A-12.     In this respect, both the circuit court and the
    ICA specifically referred to HRS § 658A-12(a)(2), which provides
    an example of information that must be disclosed under HRS
    § 658A-12(a), namely, “[a]n existing or past relationship with
    any of the parties . . . , their counsel or representatives, a
    witness, or another arbitrator.”           However, notwithstanding
    whether the nondisclosure at issue here falls under the
    definition of HRS § 658A-12(a)(2), the nondisclosure may still
    result in a violation of the more general disclosure requirement
    in both HRS § 658A-12(a) and (b) of facts that “a reasonable
    31
    ____*** FOR PUBLICATION IN WEST’S HAWAIʻI REPORTS AND PACIFIC REPORTER ***____
    person would consider likely to affect the impartiality of the
    arbitrator.”18
    Thus, even if the relationship at issue is a
    prospective or future relationship, a failure to disclose may
    result in a reasonable impression of partiality, and
    accordingly, a violation of HRS § 658A-12(a) or (b).             Here, the
    fact that the relationship between Cades was—to a certain
    extent—prospective in nature is not determinative, particularly
    given the broad view of the reasonable impression of partiality
    standard employed in the relevant case law.           For example, in
    Valrose, the United States District Court for the District of
    Hawaii vacated an arbitration award in a construction dispute
    where the arbitrator and one of the party’s counsel had an ex
    parte discussion regarding the possibility of the arbitrator
    serving as the mediator in an unrelated malpractice 
    case. 105 F. Supp. 2d at 1120
    , 1125.       The discussion occurred during the
    pendency of the arbitration proceedings, and the arbitrator was
    appointed to mediate the malpractice case while the arbitration
    18
    In Nordic, although we determined that “counsel” under HRS
    § 658A-12(a)(2) “does not include all attorneys in the law firm of an
    attorney representing a party to an arbitration,” we noted that HRS
    § 658A-12(a) “requires that an arbitrator disclose facts that a reasonable
    person would consider likely to affect the arbitrator’s impartiality.” 136
    Hawaiʻi at 
    47-48, 358 P.3d at 19-20
    . “Depending on the circumstances, such
    facts could include an arbitrator’s relationships with other attorneys within
    a law firm of counsel representing a party to the arbitration.” 
    Id. at 48,
    358 P.3d at 20.
    32
    ____*** FOR PUBLICATION IN WEST’S HAWAIʻI REPORTS AND PACIFIC REPORTER ***____
    was pending, but the arbitrator failed to disclose the
    discussion.    
    Id. The only
    evidence in the record of work on the
    malpractice case that occurred during the pendency of the
    construction arbitration, however, was one conversation between
    the arbitrator and the attorneys in the malpractice case.                
    Id. at 1123.
       The court acknowledged that there was no evidence that
    party counsel acted with “improper motive” or was attempting to
    bias the arbitrator, but nonetheless concluded that “the
    nondisclosure of the discussion and appointment . . . was
    clearly a serious failing” resulting in a reasonable impression
    of partiality and requiring vacatur.         
    Id. at 1123-24.
    Similarly, in New Regency Prods., Inc. v. Nippon
    Herald Films, Inc., the Ninth Circuit affirmed a decision to
    vacate an arbitration award based on the undisclosed fact that
    the arbitrator was a senior executive of a film company that was
    in negotiations with an executive of one of the parties to co-
    produce a movie.     
    501 F.3d 1101
    , 1103 (9th Cir. 2007).          The
    arbitrator started his employment with Yari Film Group in mid-
    July 2004, during the pendency of the arbitration, and in late
    July 2004 it was reported that Yari Film Group was in
    negotiations to finance a film that would be produced by a
    production executive at New Regency, one of the parties to the
    arbitration.    
    Id. at 1107.
        Rather than focusing on the finality
    33
    ____*** FOR PUBLICATION IN WEST’S HAWAIʻI REPORTS AND PACIFIC REPORTER ***____
    of the deal between Yari Film Group and New Regency, the court
    emphasized the fact that the negotiations occurred during the
    arbitration.    
    Id. at 1110.
        Despite the lack of evidence that
    the arbitrator had actual knowledge of the negotiations, the
    court held that his failure to disclose demonstrated a
    “reasonable impression of partiality . . . sufficient to support
    vacatur.”    
    Id. at 1111.
        Recently, in In re Sussex, based in
    part on New Regency’s holding, the Ninth Circuit stated that
    evident partiality could be demonstrated not only in cases where
    there was a “direct financial connection[] between a party and
    an arbitrator or its law firm” but also when there is a
    “concrete possibility of such connections.”           In re Sussex, 
    781 F.3d 1065
    , 1074 (9th Cir. 2015) (emphasis added) (citing
    
    Schmitz, 20 F.3d at 1044
    , 1049; New 
    Regency, 501 F.3d at 1103
    ),
    cert. denied sub nom. Turnberry/MGM Grand Towers, LLC, v.
    Sussex, 
    136 S. Ct. 156
    (2015).
    The facts in the instant case are analogous to Valrose
    and New Regency, and comport with the Ninth Circuit’s
    explanation that a failure to disclose a “concrete possibility”
    of a connection between an arbitrator and a party or party law
    firm can result in a reasonable impression of partiality.              In re
    
    Sussex, 781 F.3d at 1074
    .       Although it appears that Cades did
    not begin to formally represent Yim during the arbitration, it
    34
    ____*** FOR PUBLICATION IN WEST’S HAWAIʻI REPORTS AND PACIFIC REPORTER ***____
    is clear that PSC, serving as Yim’s agent, had discussions
    during the pendency of the proceedings related to Cades’s
    potential representation of Yim.           Indeed, Cades completed a
    conflict check for Yim in June 2011 after Yim’s appointment as
    arbitrator.    Cades actually received Yim’s files prior to the
    issuance of the Partial Final Award, indicating that the
    attorney-client relationship was—at the least—close to being
    consummated.    Additionally, Yim still planned on being
    represented by Cades in February 2012, prior to the release of
    his Final Award.     In an email he sent to DPR the day prior to
    the first supplemental disclosure, Yim indicated that he would
    be billed directly by Cades for its work but would have minimal
    direct interaction with the firm.           Relatedly, per Yim’s first
    supplemental disclosure, Yim anticipated “sign[ing] documents
    drafted by Cades” and receiving invoices directly from Cades for
    “compliance work done on his account.”
    In sum, the timing of the undisclosed relationship
    lends to our conclusion that the circuit court clearly erred in
    determining that Yim’s failure to disclose did not result in
    evident partiality, because the communications between PSC—
    acting on Yim’s behalf—and Cades occurred during the pendency of
    the arbitration, or otherwise stated, were not “distant in time,
    but rather ongoing during the arbitration.”           New Regency, 501
    35
    ____*** FOR PUBLICATION IN WEST’S HAWAIʻI REPORTS AND PACIFIC REPORTER ***____
    F.3d at 1110.     The operative facts demonstrate that—at the
    least—there was a concrete possibility that an attorney-client
    relationship would develop between the arbitrator and the law
    firm of party counsel.
    We are further persuaded that the circuit court’s
    conclusion regarding evident partiality was erroneous, given the
    substantive nature of the undisclosed relationship.            In this
    respect, we also disagree with the ICA’s conclusion that Yim’s
    failure to disclose did not result in a reasonable impression of
    partiality based on the indirectness and insignificance of his
    relationship with Cades.       The ICA noted that Yim did not plan on
    having direct interaction with Cades other than paying legal
    bills, and on this basis described the relationship as “arms-
    length.”    Madamba, SDO, 
    2014 WL 2180001
    , at *4 (internal
    quotation marks omitted).       However, the fact that PSC would have
    acted as an intermediary between Yim and Cades is not
    determinative.     Indeed, had Cades ultimately completed the work
    on Yim’s retirement accounts, Cades would have been acting as
    Yim’s personal attorney, resulting not only in a business and
    financial relationship, but also an attorney-client
    relationship, which carries with it heightened import.
    Other courts have found a failure to disclose
    resulting in a reasonable impression of partiality based on more
    36
    ____*** FOR PUBLICATION IN WEST’S HAWAIʻI REPORTS AND PACIFIC REPORTER ***____
    distant relationships than the one at issue here.            In New
    Regency, as 
    discussed supra
    , the undisclosed relationship at
    issue was between a film company at which the arbitrator had
    been made a senior executive and an executive employed at New
    
    Regency. 501 F.3d at 1103
    .     The arbitrator had no direct role
    in the negotiations between the two companies, and in fact, the
    record lacked evidence that the arbitrator was even aware of the
    potential relationship.       
    Id. at 1107-08.
        Moreover, the New
    Regency executive who communicated with the arbitrator’s film
    company did not appear to be “directly representing New Regency
    in the negotiations.”      
    Id. at 1110-11.
         Nonetheless, the court
    concluded the executive’s ties to New Regency were of sufficient
    import to distinguish the relationship as more than attenuated.
    
    Id. The court’s
    determination in this regard contributed to its
    holding that the district court properly vacated the arbitration
    award.   Id.; see also Olson v. Merrill Lynch, Pierce, Fenner &
    Smith, Inc., 
    51 F.3d 157
    , 159 (8th Cir. 1995) (holding that the
    arbitrator’s failure to disclose his company’s business dealings
    with one of the parties required vacatur although the arbitrator
    was not “personally involved” in the relationship); 
    Schmitz, 20 F.3d at 1044
    , 1049 (finding evident partiality where the
    arbitrator’s law firm previously represented a parent company of
    one of the parties); Houston Vill. Builders, Inc. v. Falbaum,
    37
    ____*** FOR PUBLICATION IN WEST’S HAWAIʻI REPORTS AND PACIFIC REPORTER ***____
    
    105 S.W.3d 28
    , 34 (Tex. App. 2003) (stating that the
    arbitrator’s “ongoing service as counsel” for a trade
    association of which parties were members “might create a
    reasonable impression of partiality toward” those parties).
    Similarly, in Nordic, we cited favorably to a Texas
    Supreme Court case in which the court—adopting the reasonable
    impression of partiality standard—found evident partiality,
    based on an arbitrator’s failure to disclose a more indirect
    relationship than the one at issue here.          136 Hawaiʻi at 
    48-49, 358 P.3d at 20-21
    .      In the Texas case, each party to the
    arbitration at issue selected an arbitrator to serve as a party
    arbitrator, i.e., a non-neutral arbitrator.           Burlington N. R.R.
    Co. v. TUCO Inc., 
    960 S.W.2d 629
    , 630 (Tex. 1997).            The two
    party arbitrators then selected the third arbitrator, meant to
    “act as the only neutral decision maker.”          
    Id. It was
    later
    revealed that during the arbitration, the neutral arbitrator
    accepted “a substantial referral from the law firm of [one of
    the] non-neutral co-arbitrator[s].”         
    Id. The arbitrator
    failed
    to disclose his acceptance of the work during the arbitration.
    
    Id. Despite arguments
    that the “relationship [was] too indirect
    because [the law firm at issue] was neither a party in the
    arbitration proceedings nor counsel for a party,” the court
    determined “that a reasonable person could conclude that the
    38
    ____*** FOR PUBLICATION IN WEST’S HAWAIʻI REPORTS AND PACIFIC REPORTER ***____
    referral might affect [the neutral arbitrator’s] impartiality”
    and accordingly, “trigger[ed] the duty to disclose.”             
    Id. at 638,
    639.    The court further noted, that although neither the
    non-neutral arbitrator nor the attorney who made the referral
    was aware of the other’s relationship with the neutral
    arbitrator, “[a]n objective observer could still reasonably
    believe that a person in [the neutral arbitrator’s] position,
    grateful for the referral, may have been inclined to favor [the
    law firm] as an entity,” and accordingly, may have been partial
    toward the position of the co-arbitrator whose firm referred
    him.   
    Id. at 637.
    Here, in contrast to Burlington, the law firm with
    whom Yim had an undisclosed relationship—i.e., Cades—was
    representing a party to the arbitration and accordingly,
    functioned as an agent to one of the parties to the arbitration.
    Cf. 
    id. at 640
    (Enoch, J., dissenting) (noting that the non-
    neutral arbitrator “was chosen” by one of the parties but was
    “not their agent”).      Further, the nature of the undisclosed
    relationship between Yim and Cades was more significant than the
    relationship between the arbitrator in Burlington and the law
    firm of his co-arbitrator.       In Burlington, another attorney at
    the co-arbitrator’s law firm had merely facilitated a meeting
    between the neutral arbitrator and the potential client.              
    Id. at 39
    ____*** FOR PUBLICATION IN WEST’S HAWAIʻI REPORTS AND PACIFIC REPORTER ***____
    631.    Notably, although the referring attorney “attended the
    meeting and briefed the other participants” on certain issues
    regarding the litigation, “he had no authority to determine
    whether [the neutral arbitrator] should be hired.”            
    Id. Further, there
    was no indication in Burlington that the law firm
    would be involved in the litigation, beyond the initial
    referral.    In contrast, in the instant case, Yim failed to
    disclose a relationship that could have resulted in the Romeros’
    counsel’s law firm directly representing Yim in his personal
    capacity.    As previously noted, this would include signing
    documents that Cades prepared and paying Cades directly for its
    work.
    In sum, based on this record, we conclude that the
    circuit court clearly erred in its determination that Yim’s
    failure to disclose did not result in evident partiality.              We
    recognize that whether a failure to disclose creates a
    reasonable impression of partiality is a fact-driven question
    requiring a close analysis of the circumstances at issue.              Here,
    the communications between PSC—acting as Yim’s agent—and Cades
    were not distant in time, but instead were ongoing during the
    arbitration.    In terms of substance, the anticipated
    relationship between Cades and Yim would have resulted in an
    attorney-client relationship with Cades representing Yim in his
    40
    ____*** FOR PUBLICATION IN WEST’S HAWAIʻI REPORTS AND PACIFIC REPORTER ***____
    personal capacity.      Moreover, Yim’s relationship with Cades was
    more than merely a prospective one, as Cades received the files
    related to Yim’s retirement accounts during the pendency of the
    arbitration.     It is also significant that Yim did not begin to
    disclose his relationship with Cades until after he issued the
    Partial Final Award.
    Yim’s failure to disclose his potential relationship
    with Cades prior to accepting appointment resulted in a
    violation of HRS § 658A-12(a) and his failure to disclose “facts
    . . . [he] learn[ed] after accepting appointment” resulted in a
    violation of HRS § 658A-12(b).        If Yim had disclosed there was a
    fifty percent chance Cades would be retained to review his
    retirement accounts prior to the arbitration, it would have been
    reasonable for a litigant in Madamba’s position to reject Yim as
    an arbitrator.     See Kay, 119 Hawaiʻi at 
    230, 194 P.3d at 1192
    (“It would have been perfectly reasonable and rational for a
    person in [the relevant party’s] position to have rejected an
    arbitrator who had such connections—if disclosure had been
    made.”); see also 
    Schmitz, 20 F.3d at 1047
    (“The parties can
    choose their arbitrators intelligently only when facts showing
    potential partiality are disclosed.”).          Moreover, throughout the
    arbitration proceedings, while Cades and PSC continued to work
    towards finalizing the attorney-client relationship between
    41
    ____*** FOR PUBLICATION IN WEST’S HAWAIʻI REPORTS AND PACIFIC REPORTER ***____
    Cades and Yim, Yim did not make any related disclosures.              Under
    these circumstances, we conclude that a reasonable impression of
    partiality was established.
    2) A Finding of Evident Partiality Requires Vacatur
    As 
    explained supra
    , the undisclosed facts demonstrated
    a reasonable impression of partiality, and accordingly, resulted
    in a violation of the HUAA’s disclosure requirements.             Because
    Yim was a neutral arbitrator, evident partiality was established
    as a matter of law.      See Nordic, 136 Hawaiʻi at 
    22, 358 P.3d at 50
    .   Thus, the arbitration award must be vacated pursuant to HRS
    § 658A-23(a)(2)(A), which provides that the court “shall vacate
    an award made in the arbitration proceeding” upon a motion by a
    party to the proceeding if there was “[e]vident partiality by an
    arbitrator appointed as a neutral arbitrator[.]” (Emphasis
    added).
    As 
    noted supra
    , HRS § 658A-12(c) and (d) provide that
    if an arbitrator fails to disclose a fact required under
    subsections (a) or (b) of the statute, or if the arbitrator does
    disclose such a fact but continues to serve as arbitrator—
    following timely objection—the award “may” be vacated under HRS
    § 658A-23(a)(2).     The function of the “may” language in the
    statutes is to provide reference to the different circumstances
    that require vacatur under HRS § 658A-23(a)(2), i.e., a neutral
    42
    ____*** FOR PUBLICATION IN WEST’S HAWAIʻI REPORTS AND PACIFIC REPORTER ***____
    arbitrator’s evident partiality, and any arbitrator’s corruption
    or misconduct.     Supra note 14.     For example, if a non-neutral
    arbitrator fails to make a disclosure required under HRS § 658A-
    12(a) or (b), although the award would not be vacated based on
    evident partiality—as evident partiality only applies to neutral
    arbitrators—it could be vacated based on the corruption and
    misconduct provisions in HRS § 658A-23(a)(2).19
    In Nordic, because we remanded the case to the circuit
    court for an evidentiary hearing, we did not directly address
    the effect of a finding of evident partiality on a motion to
    vacate.    However, we stated that the circuit court “has
    discretion under HRS § 658A-12(d) to decide whether or not to
    grant the motion to vacate.”        Nordic, 136 Hawaiʻi at 
    53, 358 P.3d at 25
    .20   We now clarify that pursuant to the plain language of
    19
    The HUAA is based on the Uniform Arbitration Act (UAA), drafted
    by the National Conference of Commissioners on Uniform Laws in 2000. The
    comment to section 12 of the UAA, which mirrors HRS § 658A-12 states as
    follows: “A party-appointed, non-neutral arbitrator’s failure to disclose
    would be covered under the corruption and misconduct provisions of Section
    23(a)(2) because in most cases it is presumed that a party arbitrator is
    intended to be partial to the side which appointed that person.” Unif.
    Arbitration Act § 12 cmt. 4 (2000), available at
    http://www.uniformlaws.org/shared/docs/arbitration/arbitration_final_00.pdf.
    For a non-neutral arbitrator, the award would only be vacated if the
    arbitrator “fails to disclose information that amounts to ‘corruption’ or to
    ‘misconduct prejudicing the rights of a party.’” 
    Id. cmt. 5.
    20
    In Nordic, we noted that the commentary to UAA section 12
    provides that “[c]ourts also are given wider latitude in deciding whether to
    vacate an award under Section 12(c) and (d) that is permissive in nature (an
    award ‘may’ be vacated) rather than Section 23(a) which is mandatory (a court
    (continued . . .)

    HRS § 658A-23(a)(2), if a neutral arbitrator demonstrates
    evident partiality, the arbitration award shall be vacated.21
    B.    Discovery Issues
    Because we find that based on the record before us
    Yim’s failure to disclose requires vacating the arbitration
    award, we need not address the circuit court’s disposition of
    Madamba’s request for additional discovery.           However, we note
    that the ICA’s determination that Madamba was not entitled to
    take Yim and DPR staff depositions based on DPR’s claim of
    immunity was incorrect.       See Madamba, SDO, 
    2014 WL 2180001
    , at
    *4.   Pursuant to HRS § 658A-14(d)(2), an arbitrator or a

    However, the comment also notes that “[c]hallenges based upon a lack of
    impartiality, including disclosed or undisclosed facts, interests, or
    relationships are subject to the developing case law under Section 23(a)(2).”
    Unif. Arbitration Act § 12 cmt. 4. Thus, the comment takes into account the
    fact that jurisdictions have developed different views regarding what
    constitutes evident partiality. As 
    discussed supra
    , our standard for evident
    partiality based on a failure to disclose is equivalent to the standard laid
    out in HRS § 658A-12’s disclosure provisions. Accordingly, in this context,
    once evident partiality is established, the arbitration award must be
    vacated.

    We note that in the instant case, there was no issue as to
    whether Madamba waived his right to challenge Yim’s role as arbitrator. A
    party’s right to challenge an arbitration award based on a failure to
    disclose and evident partiality may be waived under certain circumstances.

    testifying unless the testimony is related “[t]o a hearing on a
    motion to vacate an award under section 658A-23(a)(1) or (2) if
    the movant establishes prima facie that a ground for vacating
    the award exits.”     Here, Madamba met its burden in establishing
    prima facie grounds to vacate the award, pursuant to the
    preceding discussion.      Accordingly, Yim and DPR personnel were
    not immune from testifying.
    III. Conclusion
    For the foregoing reasons, we vacate the ICA’s June
    20, 2014 judgments on appeal in CAAP-12-0000778 and CAAP-12-
