    2.       “‘Judicial review of an agency’s legislative rule and the construction of a
    statute that it administers involves two separate but interrelated questions, only the second
    of which furnishes an occasion for deference. In deciding whether an administrative

     (1984). The court first must
    ask whether the Legislature has directly spoken to the precise question at issue. If the
    intention of the Legislature is clear, that is the end of the matter, and the agency’s position
    only can be upheld if it conforms to the Legislature’s intent. No deference is due the
    agency’s interpretation at this stage.’ Syl. Pt. 3, Appalachian Power Co. v. State Tax Dep't

    its own construction of the statute in reviewing a legislative rule. Rather, if the statute is
    silent or ambiguous with respect to the specific issue, the question for the court is whether
    the agency’s answer is based on a permissible construction of the statute. A valid legislative
    rule is entitled to substantial deference by the reviewing court. As a properly promulgated

    WOOTON, J.:
    In these consolidated cases we are called upon to examine the State Health
    Plan Home Health Services Standards (“the Standards”), which were promulgated by
    respondent West Virginia Health Care Cost Review Authority (“HCCRA”), now the West
    Virginia Health Care Authority (“the Authority”), as part of its duties and responsibilities
    pursuant to West Virginia Code §§ 16-2D-1 to -20 (2016 & Supp. 2020). The Standards
    were approved by the Governor on November 13, 1996. The Standards govern the
    Authority’s consideration of applications from individuals and entities seeking to provide
    home health care services in a particular county, and include, inter alia, a methodology for
    determining whether there is an unmet need for such services in the county. If the
    Authority determines that an applicant has demonstrated the existence of unmet need and
    has otherwise satisfied all other requirements imposed by the Standards, the agency issues
    a Certificate of Need (“CON”) allowing the applicant to offer services in the county.
    Petitioners Amedisys West Virginia, L.L.C. dba Amedisys Home Health of
    West Virginia, St. Marys Medical Center Home Health Services, LLC, and LHC Group,
    Inc. (“the Amedisys petitioners”) and petitioners Preston Memorial Homecare, LLC and
    Tender Loving Care Health Care Services of West Virginia, LLC dba Amedisys Home
    Health of West Virginia (“the Preston Memorial petitioners”) (referred to collectively as
    “petitioners”) contend that unmet need cannot be established unless the evidence shows
    that at least 229 individuals in the county in question are in need of home health care
    services. Respondents Personal Touch Home Care of W. Va., Inc. (“Personal Touch”),
    1
    United Hospital Center, Inc. (“United”), and The West Virginia Health Care Authority
    (“the Authority”) (referred to collectively as “respondents”) counter that in an unbroken
    line of precedents dating back at least to 2002, the Authority’s position has been that any
    number of individuals in need of the services – whether it’s 1 or 100 or 1,000 – can be
    deemed sufficient to establish unmet need in the county. According to respondents, the
    229 figure is an average county usage figure that comes into play only where another home
    health care provider has begun offering services in the county during the preceding 12-
    month period; in such case, the Standards require the new applicant to demonstrate a need
    at or beyond the 229 average usage figure, a requirement intended to give the recently
    established provider sufficient time to develop and grow its business before having to
    compete with a newcomer.
    With this background in mind, we turn to the factual and procedural posture
    in these consolidated cases and then examine the single, dispositive issue presented in both.
    After review, and for the reasons explained herein, the decisions of the circuit court in No.
    20-0308 and No. 20-0401 are affirmed.
    I. Facts and Procedural Background
    No. 20-0308
    In the first case, the Amedisys petitioners contend that a CON issued by the
    Authority to respondent Personal Touch was improper in that Personal Touch failed to
    2
    demonstrate the requisite unmet need for additional home health services in Cabell and
    Wayne Counties.
    On August 10, 2018, Personal Touch filed its application for a CON allowing
    it to expand its existing home health care services into Cabell and Wayne Counties. See
    id. § 16-2D-8(b)(23). In this regard, “[a] certificate of need may only be issued if the
    proposed health service is: (1) Found to be needed; and (2) Consistent with the state health
    plan, unless there are emergency circumstances that pose a threat to public health.” See id.
    § 16-2D-12(a). According to the calculations contained in the application filed by Personal
    Touch, which followed the methodology contained in Section V(C)(1) – (3) of the
    Standards, 1 the unmet need for home health care services was 29 individuals in Cabell
    County and 55 individuals in Wayne County.
    On August 14, 2018, the application was deemed complete, see id. § 16-2D-
    13(c), and two days later, on August 16, 2018, the Authority issued a Notice of Review.
    1
    The methodology actually contains four calculations: the first compares the county
    and state home health utilization rates; the second determines the number of potential home
    health care recipients needed to reach the state rate; the third determines the actual number
    of home health care recipients below the state rate; and the fourth, which comes into play
    only where there are agencies in the county which received CON approval within the
    previous 12 months, applies an adjustment factor to determine unmet need. See text infra
    for a detailed discussion of these calculations. See Standards, V(C)(1) – (4), “Determining
    Unmet Need for Home Health Services.” Because none of the existing home health
    services providers in either Cabell County or Wayne County had received a CON during
    the 12-month period preceding Personal Touch’s application, see text infra, the fourth
    calculation was not applicable.
    3
    See id. § 16-2D-13(d).       Thereafter, the Amedisys petitioners sought recognition as
    “affected persons,” statutorily defined in relevant part as “health care facilit[ies] located
    within this state which provide services similar to the services of the facility under review
    and which will be significantly affected by the proposed project.” See id. § 16-2D-2(1)(E).
    Of particular relevance to this case, it is important to note that all existing home health care
    providers in Cabell and Wayne County, 2 including the Amedisys petitioners, had been
    providing such services for more than 12 months preceding Personal Touch’s application
    for a CON.
    On December 12, 2018, a public hearing was held to determine whether the
    application of Personal Touch for a CON, which would allow it to expand its services into
    the counties in question, should be granted or denied by the Authority. To establish their
    case as affected parties, the Amedisys petitioners called Charles G. Gibbs, a health care
    consultant who was recognized as an expert in the field, to testify on their behalf. Mr.
    Gibbs took issue with the Personal Touch application in three respects. First, he contended
    that Personal Touch had based its unmet need calculations on 3-year-old data from fiscal
    year 2015, rather than on updated data from fiscal year 2017 which had been made publicly
    available on July 31, 2018, 10 days before Personal Touch filed its application. 3 In this
    2
    The record discloses that during the relevant time period, there were ten home
    health care providers in Cabell County and eleven in Wayne County.
    3
    See text infra.
    4
    regard, Mr. Gibbs noted that the form used for applying for a CON specifies that “readily
    available data” be used and argued that the updated data was readily available in time to
    have been incorporated into the application. Second, Mr. Gibbs argued that Personal
    Touch had applied the wrong methodology for determining unmet needs in Cabell and
    Wayne County, in that it failed to apply the adjustment factor contained in section V(C)(4)
    of the Standards. See supra note 1. Mr. Gibbs acknowledged that the methodology utilized
    by Personal Touch comported with the Authority’s longstanding interpretation of the
    Standards, specifically, that the adjustment factor came into play only in situations where
    other agencies in a county had received CON approval within the past 12 months. 4 He
    argued, however, that the Authority’s interpretation was wrong. In that regard, he testified
    that before the Standards were adopted in their final form, HCCRA had developed a sample
    application form that applied the adjustment factor in all cases, not just in the limited
    4
    Evidence submitted at the hearing demonstrated that CON approval had been
    given in 2002 for provision of home health services where the unmet need in Wayne
    County was 69 patients; again in 2002 where the unmet need in Wayne County was 75
    patients; in 2003 where the unmet need in Jackson County was 127 patients, the unmet
    need in Putnam County was 386 patients, and the unmet need in Lincoln County was 97
    patients; again in 2003 where the unmet need in Boone County was 125 patients, the unmet
    need in Cabell County was 5 patients, the unmet need in Lincoln County was 98 patients,
    the unmet need in Logan County was 180 patients, and the unmet need in Wyoming County
    was 212 patients; in 2004, where the unmet need in Berkeley County was 195 patients;
    again in 2004, where the unmet need in Wyoming County was 76 patients; in 2008, where
    the unmet need in Lincoln County was 30 patients, and the unmet need in Wayne County
    was 19 patients; in 2015, where the unmet need in Berkeley County was 961 patients, the
    unmet need in Hampshire County was 203 patients, the unmet need in Jefferson County
    was 606 patients, the unmet need in Morgan County was 116 patients, and the unmet need
    in Mineral County was 130 patients; in 2017, where the unmet need in Pleasants County
    was 8 patients, and the unmet need in Tyler County was 6 patients.
    5
    situation set forth above. He further testified that in 1997, two CON applications that had
    been decided by HCCRA 5 had specifically referred to, and applied, the 229 figure as a
    threshold, not an adjustment, although he acknowledged that at least since 2002, the
    Authority had consistently taken the opposite position. Mr. Gibbs further testified to the
    fact that on January 11, 2010, another health care expert, Raymona Kinneberg, then-
    advisor to the Authority’s Certificate of Need Director, wrote a letter in which she
    expressed agreement with Mr. Gibbs’ opinion, stating that “no new agencies should be
    approved in a county where the number of unserved patients was below the threshold set
    in the standards, whether or not a new agency had been approved in the previous year.” 6
    Mr. Gibbs also opined that what he deemed to be the Authority’s “mistake” ‒ failing to
    recognize that the adjustment factor should be applied in all cases ‒ has been perpetuated
    in large part by the Authority’s failure to “consider adjusting the threshold adjustment
    factor at the time it updates the need calculations[,]” 7 in the 25 years which have elapsed
    since the Standards were established. Finally, Mr. Gibbs noted that in 2007, in a CON
    5
    In re: Pro Careers, Inc., CON File No. 96-3/9-5726-Z (Mar. 17, 1997); In re:
    Critical Care Nursing Agency, Inc., CON File No. 96-2/3-5790-Z/Z (Mar. 20, 1997).
    6
    Ms. Kinneberg, who later became president of United, now holds a contrary view.
    See text infra.
    7
    It appears that Mr. Gibbs’ reference to updating “the needs calculations” was not
    a reference to the structure of the methodology, which has never been updated, but to the
    population data which is incorporated into the methodology. Although the record is not
    entirely clear on this point, it appears that the methodology is updated every two years with
    new data. An applicant works from the population data contained in the latest “Home
    Health Care Methodology” that the Authority makes publicly available. See text infra.
    6
    appeal in the Circuit Court of Mason County, 8 the court had held that the Authority’s
    interpretation of Section V(C) of the Standards “results in absurd and conflicting decisions”
    in that it would be possible “to approve an application where the projection of unmet need
    is between 1 and 228 available new patients and also deny one with the same projected
    result.” 9 See text infra. Third, Mr. Gibbs testified that with the Amedysis petitioners and
    others already providing home health services in Cabell and Wayne Counties, consumers
    have adequate choice and no need for additional services. Therefore, in Mr. Gibbs’ view,
    the status quo should be maintained.
    On April 4, 2019, the Authority issued its Decision, approving Personal
    Touch’s CON application, conditioned on Personal Touch’s submission of annual reports
    for the first three years of operation showing “the actual utilization and revenue and
    expenses compared to the projections presented[.] In this regard, the Authority specifically
    concluded, in relevant part, that “[p]atients will continue to experience serious problems in
    obtaining care of the type proposed in the absence of the proposed project,” that “[t]he
    project is consistent with the State Health Plan,” and that “[t]he project will serve the
    medically underserved population.” The Amedysis petitioners filed a timely Request for
    8
    Effective March 30, 2017, all appeals from a decision of the Office of Judges in a
    case involving the grant or denial of a CON are filed in the Circuit Court of Kanawha
    County. See id. § 16-2D-16(f).

    Review by the Health Care Authority/Office of Judges, and on September 28, 2019,
    following briefing and argument, the administrative law judge determined “that the
    Authority did not err in approving the Personal Touch CON for home health services in
    Cabell and Wayne Counties,” and affirmed the April 4, 2019, decision.
    On October 23, 2019, the Amedysis petitioners filed an administrative appeal
    in the Circuit Court of Kanawha County. By order entered on February 28, 2020, the court
    affirmed the decision of the Office of Judges and specifically found that the “decision is
    correct and . . . the Authority did not err in approving the Personal Touch CON for home
    health services in Cabell and Wayne counties, West Virginia.” This appeal followed.
    No. 20-0401
    In the second case, the Preston Memorial petitioners contend that a CON
    issued by the Authority to respondent was improper in that United failed to demonstrate
    unmet need for additional home health services in Preston County.
    United is a 292-bed acute care hospital located in Harrison County, West
    Virginia. At the time of events relevant to this case, it was the only provider of inpatient
    and outpatient acute care in Harrison County, and provided a range of inpatient and
    outpatient acute care services in Doddridge County as well. Additionally, United provided
    hospital and home health services in Harrison County and surrounding areas, and provided
    home health care services in Barbour, Doddridge, Harrison, Lewis, Marion, Taylor, and
    8
    Upshur Counties. On July 17, 2017, United filed its application for a CON allowing it to
    expand its existing home health care services into Preston County. According to the
    calculations contained in the application filed by United, which followed the methodology
    contained in Section V(C) of the Standards, the unmet need for home health care services
    was 44 individuals in Preston County.
    On July 18, 2017, the application was deemed complete, and on August 1,
    2017, the Authority issued an Amended Notice of Review. Thereafter, the Preston
    Memorial petitioners sought recognition as “affected persons” and asked for a hearing.
    Once again, it is important to note that all 5 existing home health care providers in Preston
    County, including the Preston Memorial petitioners, had been providing services in Preston
    County for more than 12 months preceding the date of United’s application.
    On December 7, 2017, a public hearing was held to determine whether the
    application of United for a CON, which would allow it to expand its services into Preston
    County, should be granted or denied by the Authority. United put on testimony and
    evidence to support its contention that such expansion would be beneficial in a number of
    respects. First, because many Preston County patients are released from WVU hospitals
    with very complicated needs, home health services provided by United would provide
    continuity of care, immediate access to medical records which, in turn, would allow for
    better communication and coordination of services, and access to some of WVU hospitals’
    medical experts, particularly in the Heart and Vascular Institute. Additionally, United
    9
    noted that it takes home health services patients who would not be accepted by other
    providers, specifically, patients known to be noncompliant and “have a variety of issues
    that can negatively affect your quality scores because they use the emergency room, they
    get readmitted, they don’t follow their diabetic diet, they don’t take their medications.”
    United also presented testimony and evidence to support its contention that
    the proposed expansion of its home health services into Preston County was financially
    feasible, in large part by “help[ing] us to reduce readmissions . . . that cost approximately
    $2,600 per admission.” Finally, of specific relevance to this appeal, United offered
    testimony and evidence to support its projection that in its first year of operation in Preston
    County, it would provide services to 44 patients whose need was currently unmet, 10 as well
    as to 56 patients shifted from other services already in operation in the county. Testimony
    on this issue was given by Raymona Kinneberg, President of United, who supported its
    contention that 44 unmet needs patients was sufficient to support its application for a CON,
    and that the adjustment factor of 229 unmet needs patients, see text supra, came into play
    only in situations where other agencies in a county had received CON approval within the
    past 12 months. Ms. Kinneberg acknowledged having once expressed a different opinion
    while she was serving as a consultant to the director of the State’s certificate of need
    program, but testified that she had changed her view in consideration of two factors: first,
    During the relevant time period, the state home health services utilization rate was
    10
    25/1,000 residents; based on its population, Preston County’s need was estimated to be
    875, while its actual utilization was 832, leaving unmet need of 44. See text infra.
    10
    the long, consistent interpretation of the Standards by HCA; and second, the fact that
    utilizing the 229 figure as a threshold, rather than an adjustment, would mean that based
    on their respective populations, ten counties in West Virginia 11 would never have an unmet
    need sufficient to support a CON for any home health services provider to operate therein.
    In response to United’s evidentiary presentation, the Preston Memorial
    petitioners put on their own evidence and testimony, including, in relevant part, the
    testimony of Charles Gibbs. Mr. Gibbs made the same arguments as he made in the
    Amedisys proceedings with respect to the issue of unmet need: specifically, he contended
    that using the 229 figure as a threshold in all cases, rather than simply as an adjustment
    where an existing provider had received a CON within the past 12 months, balances “the
    need for enough providers . . . while recognizing the need to protect financial viability, the
    operational viability, and the quality viability . . . [by regulating] the proliferation of home
    health systems.” In Mr. Gibbs’ view, the position taken by United, and upheld by HCA,
    that an unmet need of 44, or even 1, is sufficient to authorize a CON, is “unreasonable,
    absurd and illogical.” Mr. Gibbs also testified that the United project was not financially
    feasible, pointing out that United’s own projections showed a $103,915 loss in 2018, a
    $96,860 loss in 2019, and a $88,639 loss in 2020, for a total loss of $289,414 over three

    Webster, and Wirt.
    11
    years. 12 Finally, Mr. Gibbs noted that United had provided no letters of support for its
    proposed expansion of home health services into Preston County.
    On February 16, 2018, the Authority issued its Decision, approving United’s
    CON application. In this regard, the Authority specifically concluded, in relevant part, that
    “[p]atients will continue to experience serious problems in obtaining care of the type
    proposed in the absence of the proposed project,” that “[t]he project is consistent with the
    State Health Plan,” and that “[t]he project will serve the medically underserved
    population.” The Amedisys petitioners filed a timely Request for Review by the Health
    Care Authority/Office of Judges, and on June 27, 2018, following briefing and argument,
    the administrative law judge determined “that the Authority did not err in approving the
    Personal Touch CON for home health services in Preston County,” and affirmed the
    February 16, 2018, decision.
    On July 24, 2018, the Preston Memorial petitioners filed an administrative
    appeal in the Circuit Court of Kanawha County. By order entered on May 20, 2020, the
    12
    United’s evidence on this point was that expansion of its home health care services
    program into Preston County was economically feasible. In this regard, United’s Chief
    Financial Officer testified that United had based its financial projections “on how its home
    health agency actually operates ‒ as a single unit and not as distinct counties.” Based on
    the totality of the evidence, the Authority concluded that “[United] has the resources to
    cover any losses initially created by expanding its home health services to Preston County.
    The Authority finds that [United] has adequately addressed the Standards as they pertain
    to the financial feasibility of this project and this project is financially feasible.”
    12
    court affirmed the decision of the Office of Judges and specifically found that the decisions
    of the Authority and the Office of Judges awarding a CON to United “were supported by
    substantial evidence on the whole record; were rendered in accordance with law; were not
    arbitrary or capricious; and did not constitute an abuse of discretion or clearly unwarranted
    exercise of discretion.” This appeal followed.
    II. Standard of Review
    At the initial review level, West Virginia Code § 16-2D-16 provides, in
    relevant part, that an appeal is processed by the Office of Judges “in accordance with the
    provisions governing the judicial review of contested administrative cases in article five,
    chapter twenty-nine-a of this code.” The specific standard of review both for the Office of
    Judges and, on appeal therefrom, the circuit court, is set forth in West Virginia Code §
    29A-5-4(g) (2016):
    ‘“‘Upon judicial review of a contested case under the
    West Virginia Administrative Procedure Act, Chapter 29A,
    Article 5, Section 4(g), the circuit court may affirm the order
    or decision of the agency or remand the case for further
    proceedings. The circuit court shall reverse, vacate or modify
    the order or decision of the agency if the substantial rights of
    the petitioner or petitioners have been prejudiced because the
    administrative findings, inferences, conclusions, decisions or
    order are: ‘(1) In violation of constitutional or statutory
    provisions; or (2) In excess of the statutory authority or
    jurisdiction of the agency; or (3) Made upon unlawful
    procedures; or (4) Affected by other error of law, or (5) Clearly
    wrong in view of the reliable, probative and substantial
    evidence on the whole record; or (6) Arbitrary or capricious or
    characterized by abuse of discretion or clearly unwarranted
    exercise of discretion.’ Syllabus point 2, Shepherdstown

     (2011).
    Of specific relevance to the instant case, where the petitioners are challenging
    the legitimacy of HCA’s interpretation of its own CON Standards, we have held that
    “‘[j]udicial review of an agency’s legislative rule and
    the construction of a statute that it administers involves two
    separate but interrelated questions, only the second of which
    furnishes an occasion for deference. In deciding whether an
    administrative agency’s position should be sustained, a
    reviewing court applies the standards set out by the United
    States Supreme Court in Chevron U.S.A., Inc. v. Natural
    Resources Defense Council, Inc., 
    467 U.S. 837
    , 
    104 S. Ct. 2778
    , 
    81 L. Ed.2d 694
     (1984). The court first must ask whether
    the Legislature has directly spoken to the precise question at
    issue. If the intention of the Legislature is clear, that is the end
    of the matter, and the agency’s position only can be upheld if
    it conforms to the Legislature’s intent. No deference is due the
    agency’s interpretation at this stage.’ Syl. Pt. 3, Appalachian
    Power Co. v. State Tax Dep’t of W. Virginia,

     (2019). If the
    intention of the Legislature is not clear, or if the Legislature has not spoken to the specific
    issue, this Court will then turn to the second of the two interrelated Chevron questions.
    ‘If legislative intent is not clear, a reviewing court may not
    simply impose its own construction of the statute in reviewing
    a legislative rule. Rather, if the statute is silent or ambiguous
    with respect to the specific issue, the question for the court is
    14
    whether the agency’s answer is based on a permissible
    construction of the statute. A valid legislative rule is entitled
    to substantial deference by the reviewing court. As a properly
    promulgated legislative rule, the rule can be ignored only if the
    agency has exceeded its constitutional or statutory authority or
    is arbitrary or capricious. W. Va. Code, 29A–4–2 (1982).’ Syl.

    III. Discussion
    In West Virginia Code §§ 16-2D-1 to -20 (2016 & Supp. 2020), the West
    Virginia Legislature created the CON program, declaring it to be the State’s public policy
    “[t]hat the offering or development of all health services shall be accomplished in a manner
    which is orderly, economical and consistent with the effective development of necessary
    and adequate means of providing for the health services of the people of this state[,]” and
    further to “avoid unnecessary duplication of health services, and to contain or reduce
    increases in the cost of delivering health services.” See id. § 16-2D-1(1). Jurisdiction to
    administer the CON program was vested in the Authority, see id. § 16-2D-3(a)(1), which
    was tasked, inter alia, with “[r]eview[ing] the state health plan, the certificate of need
    standards, and the cost effectiveness of the certificate of need program and make any
    amendments and modifications to each that it may deem necessary[.]” See id. § 16-2D-
    3(a)(2).
    15
    Pursuant to the statutory framework, certain health services, including home
    health services, must be reviewed and approved by the Authority before they may be
    offered to the public in the first instance or expanded into a new area or areas. A certificate
    of need may only be issued where the offering or expansion of services is “[f]ound to be
    needed; and . . . [c]onsistent with the state health plan, unless there are emergency
    circumstances that pose a threat to public health.” See id. §§ 16-2D-12(a)(1), (2). In
    making the determination of whether a CON may be issued, the Authority utilizes
    Standards which were approved by the Governor and were thereafter in full force and effect
    from the date of the Governor’s approval. See id. § 16-2D-6(g). Of note, the Legislature
    has formally adopted the Standards and given them “full force and effect.” See id. § 16-
    2D-6(g).
    In these consolidated cases, all parties agree that the respondents’ applications
    for CONs allowing them to expand their existing home health care services into Cabell,
    Wayne, and/or Preston County, were required to be evaluated by the Authority under the
    existing Standards. 13 As part of the overall evaluations, the Agency reviewed whether the
    respondents had successfully demonstrated the existence of the respective counties’
    13
    Petitioners are highly critical of the fact that the Authority has made no changes
    to the Standards, and particularly Section V(C) thereof, since November 13, 1996, the date
    on which the Standards were approved by the Governor. However, although there is no
    question that the Authority has statutory authority to revise and upgrade the Standards, 
    W. Va. Code § 16
    -2D-6, petitioners do not contend that it has a statutory mandate to do so, or
    that this Court either could or should force the Authority to act.
    16
    “unmet need” for services, which was calculated in the first instance, and then on review,
    by utilizing the methodology set forth in Section V(C) of the Standards. In this regard, the
    “unmet need” that the respondents calculated in Cabell, Wayne, and Preston County, 29,
    55, and 44 individuals, respectively, was deemed by the Authority to be sufficient.
    Petitioners contended at all stages of the proceedings below, and contend on appeal in their
    core assignment of error, 14 that in order to establish “unmet need” a provider must establish
    the existence of no fewer than 229 individuals needing services. In this regard, the
    petitioners argue that the Authority’s interpretation of the Standards, and particularly
    section V(C)(4) thereof, “Calculation of the Threshold (Adjustment Factor),” is “[c]learly
    wrong in view of the reliable, probative and substantial evidence on the whole record; or .
    . . [a]rbitrary or capricious or characterized by abuse of discretion or clearly unwarranted
    exercise of discretion.” W. Va. Med. Imaging, 227 W. Va. at 440, 
    711 S.E.2d at 262
    , Syl.
    Pt. 1, in part. As set forth above, the Authority’s consistent and longstanding interpretation
    of the procedures set forth in Section V(C), is that the figure of 229 individuals in need of
    home health care is an adjustment factor that comes into play only where an applicant seeks
    a CON in a county or counties where another provider received a CON within the preceding
    12 months. The adjustment, says the Authority, is intended to give relatively new providers
    an opportunity to develop a client base before facing competition from brand new
    providers. In contrast, petitioners claim that the figure is a threshold factor, specifically:
    14
    Although the petitioners break the issue down into multiple parts, which this Court
    will address in turn, there is really only one issue: whether the Authority’s interpretation
    of Section V(C) of the Standards is entitled to deference. See text infra.
    17
    that whether or not another provider or providers received a CON within the preceding 12
    months, no CON can be granted unless the unmet need in a county or counties equals or
    exceeds 229 individuals.
    In order to address this issue, we first look at section V(C), “Determining
    Unmet Need for Home Health Services,” as a whole. This determination, which is made
    for any county in which a home health care provider seeks a CON, requires an applicant to
    make three or four separate calculations which are set forth in four discrete subsections.
    Of note, however, the following language is contained in the general overview which
    precedes those subsections:
    Calculation 1 compares the county and state home health
    utilization rates.
    Calculation 2 determines the extent of potential home health
    recipients in the county to reach the state utilization level.
    Calculation 3 determines the extent of potential home health
    recipients in the county to reach the state utilization level.
    Calculation 4 involves an adjustment factor for the agencies
    receiving Certificate of Need approval in the previous 12
    months to allow for their initiation and development of home
    health services. Each agency is allowed a 229-home health
    recipient adjustment factor for each county in the approved
    service area. An unmet need or threshold of at least 229
    projected home health recipients must occur in the county
    before consideration will be given to issuing another
    Certificate of Need for the County.
    (Emphasis added). With this overview in mind, we turn to the subsections describing the
    particular calculations to be made.
    18
    First, subsection (1), “Calculation of the Actual Total County Home Health
    Utilization Rate,” sets forth the methodology for calculating a county’s home health care
    utilization rate, which is expressed as a fraction: the number of persons needing home
    health care services per 1,000 citizens in the county. To find this rate, the number of home
    health care recipients in a county is divided by the county’s population for the same year,
    then multiplied by 1,000 in order to arrive at the county’s home health care utilization rate.
    It is undisputed that based on fiscal year 2015 population data, which was contained in the
    methodology utilized in the Personal Touch application, the utilization rate in Cabell
    County was 27.5/1000 and the utilization rate in Wayne County was 26.5/1000, while the
    state utilization rate was 27.8/1000. 15 It is further undisputed that based on fiscal year 2017
    population data, which was contained in the methodology utilized in the United
    application, the utilization rate in Preston County was 23.7/1000, while the state utilization
    rate was 25/1000. Pursuant to substandard V(C)(1), if a county’s utilization rate is above
    the state rate, then that is the end of the inquiry; an unmet need does not exist. If the
    county’s utilization rate is below the state rate, then the CON applicant goes on to
    subsection (2). In these consolidated cases, all of the counties’ utilization rates were below
    the state rates for the years in question.
    15
    While the Amedisys petitioners do not contest any of the V(C)(1) – (3)
    calculations in terms of the mathematics, they do contest the legitimacy of utilizing fiscal
    year 2015 data when, according to their expert witness, fiscal year 2017 data was available
    at the time Personal Touch filed its application for a CON. See text infra.
    19
    Subsection (2), “Calculation of the Actual Number of Home Health
    Recipients Needed to Obtain the State Utilization Rate,” sets forth the methodology for
    calculating the actual number of home health recipients needed to bring a county’s
    utilization rate in line with the state’s rate. To make the calculation: the number of home
    health care recipients in a county in a particular year is multiplied by the state utilization
    rate for that year, after which the resulting number is then divided by the county utilization
    rate for the year. It is undisputed that based on data from fiscal year 2015, the number of
    recipients needed to bring Cabell County’s utilization rate into line was 2,687 and the
    number needed to bring Wayne County’s utilization rate into line was 1,139. It is further
    undisputed that based on data from fiscal year 2017, the number of home health recipients
    needed to bring Preston County’s utilization rate into line was 875.
    Subsection (3), Calculation of the Actual Number of Home Health Recipients
    Below the State Rate,” sets forth the methodology for calculating the actual number of
    home health recipients below the state utilization rate. To make the calculation: the number
    of home health care recipients in a county, set forth in subsection (1), is subtracted from
    the number of home health care recipients needed to bring the county’s utilization rate in
    line with the state’s rate, set forth in subsection (2). It is undisputed that in 2017, the
    number of recipients below the state utilization rate in Cabell County was 29 and the
    number below the state rate in Wayne County was 55. It is further undisputed that in 2018,
    the actual number of home health care recipients below the state utilization rate in Preston
    County was 44.
    20
    It is at this point in the calculation that the parties’ unanimity breaks down.
    In order to understand their respective arguments, we will set forth subsection (4) verbatim.
    CALCULATION OF THE THRESHOLD (ADJUSTMENT
    FACTOR)
    (This calculation is done only if there are agencies in the proposed
    county which received CON approval in the previous 12 months.)
    Formula a – b = c
    a. List the current county home health recipients below state
    b.   Subtract adjustment factor for agencies receiving CON
    approval in previous 12 months.
    c. Number above threshold adjustment
    Conclusion:
    If the threshold is at least 229 projected home health recipients, an
    unmet need exists.
    Petitioners contend that the key here is in both the placement and the language
    of the Conclusion. First, they argue that its un-indented position on the page sets it apart
    from the subsection (4) formula, and thus it is logically a conclusion to Section V(C) of the
    Standards, “Determining Unmet Need for Home Health Services,” in its entirety, not just
    to subsection V(C)(4), “Calculation of the Threshold (Adjustment Factor).” Second, they
    argue that the preceding argument is buttressed by the use of the word “threshold” and the
    correlative omission of the word “adjustment” in the Conclusion. Therefore, petitioners
    sum up, regardless of the existence of non-existence of any other providers, and regardless
    of how long any such providers have been in business, an applicant for a CON must
    demonstrate that there are at least 229 individuals in the county in need of home health care
    services.   Respondents Personal Touch, United, and the Authority counter that in the
    21
    overview language of Section V(C), it is specifically stated that the 229 figure is “an
    adjustment factor for the agencies receiving [CON] approval in the previous 12 months to
    allow for their initiation and development of home health services.” (Emphasis added).
    Further, respondents cite the language of subsection V(C)(4), specifically, that “[t]his
    calculation is done only if there are agencies in the proposed county which received CON
    approval in the previous 12 months.” (Emphasis added). Additionally, respondents note
    the unchallenged testimony of Raymona Kinneberg that if the 229 figure were interpreted
    to be a threshold, rather than an adjustment, 10 counties in West Virginia are so sparsely
    populated that a CON could never be approved for the provision of home health care
    services for their residents. See supra note 11.
    Having addressed the parties’ respective factual contentions in broad terms,
    we now turn to the petitioner’s overarching, interrelated legal arguments: that the
    Authority’s interpretation of the Standards, specifically, that the 229 figure is an adjustment
    factor rather than a threshold factor, is arbitrary, capricious, and clearly erroneous, and
    therefore not entitled to deference by this Court; and that on de novo review, this Court
    should find the 229 figure to be a threshold factor. In this regard, this Court has adopted
    the two-part test of Chevron U.S.A., Inc. v. Nat. Res. Def. Council, 
    467 U.S. 837
     (1984),
    which “first ask[s] whether the Legislature has ‘directly spoken to the precise [legal]
    question at issue.’” Appalachian Power, 195 W. Va. at 582, 
    466 S.E.2d at 433
    . Here,
    petitioners concede that because the Standards were drafted by the Authority’s predecessor,
    22
    HCCRA, not by the Legislature, the first prong of the Chevron analysis is not applicable.
    We therefore turn to the second prong of Chevron, which asks “whether the agency’s
    answer is based on a permissible construction of the [Standards].” 
    Id.
     In determining that
    issue, we have held that “[a] valid legislative rule is entitled to substantial deference by the
    reviewing court. As a properly promulgated legislative rule, the rule can be ignored only
    if the agency has exceeded its constitutional or statutory authority or is arbitrary or
    capricious.” Murray Energy Corp. v. Steager, 241 W. Va. at 632, 827 S.E.2d at 419, Syl.
    Pt. 6, in part. However, if it is determined that an agency’s interpretation of its regulations
    is not entitled to Chevron deference, then we may interpret the regulations pursuant to our
    well-established rule that “‘[i]nterpreting a statute or an administrative rule or regulation
    presents a purely legal question subject to de novo review.’ Syl. Pt. 1, Appalachian Power
    Co. v. State Tax Dep’t of W. Va.,

    242 W. Va. 209
    , 
    832 S.E.2d 135
     (2019).
    23
    In support of both their deference and de novo review arguments, 16 petitioners
    contend that common sense, “whole-text analysis,” 17 the Merriam-Webster Dictionary, 18
    and a grammatical analysis made by the late United States Supreme Court Justice Antonin
    Scalia, 19 all mandate a finding that the word “Conclusion” at the end of Section subsection
    V(C)(4) of the Standards, “[i]f the threshold is at least 229 projected home health
    16
    This Court has long recognized the deference/de novo dichotomy which is present
    in all of the cases where the issue is an agency’s interpretation of a statute it is required by
    law to enforce and/or a regulation it has promulgated as part of that process. See, e.g., W.
    Va. Consol. Pub. Ret. Bd. v. Wood, 
    233 W. Va. 222
    , 228, 
    757 S.E.2d 752
    , 758 (2014)
    (“While this Court agrees with the proposition that the [agency’s] interpretation is entitled
    to deference, it is imperative that a reviewing court also consider the possibility . . . that
    the [agency’s] interpretation is erroneous.”).
    17
    See Weirton Med. Ctr., Inc. v. W. Va. Bd. of Med., 
    192 W. Va. 72
    , 75, 
    450 S.E.2d 661
    , 664 (1994) (“It is a cardinal rule of statutory construction that a statute should be
    construed as a whole, so as to give effect, if possible, to every word, phrase, paragraph and
    provision thereof, but such rule of construction should not be invoked so as to contravene
    the true legislative intention.’”) (citation omitted).
    18
    Petitioners note that there are three references in the Standards to a
    “threshold/adjustment” factor, and that the forward slash, or virgule, between the two
    words is significant because the word virgule is defined in the online version of the
    Merriam-Webster Dictionary as “a short oblique stroke between two words indicating
    whichever is appropriate may be chosen to complete the sense of the text in which they
    occur.” Thus, according to petitioners, when the word “adjustment” is used in V(C) and
    V(C)(4), the word should be interpreted to mean “threshold” since that would be
    “appropriate . . . to complete the sense of the text[.]” Inasmuch as there is no virgule in
    any of the relevant provisions of V(C), we decline to follow petitioners down this linguistic
    rabbit hole.

    Antonin Scalia & Bryan A. Garner, Reading Law: The Interpretation of Legal
    Texts 156 (2012) (“Material within an indented subpart relates only to that subpart;
    material contained in un-indented text relates to all the following or preceding indented
    subparts.”).
    24
    recipients, an unmet need exists[,]” applies to the entirety of the four-step process for
    determining unmet need, not just to the fourth step. This result obtains, say petitioners,
    because (a) none of the other subsections are followed by a “Conclusion,” suggesting that
    the one and only “Conclusion” in Section V(C) must apply to the entire calculation; (b) the
    “Conclusion” is not marginally aligned with the text of subsection V(C)(4), and thus cannot
    be deemed to be a part of that text; and (c) the overview language of Section V(C) includes
    the statement that “[t]he four calculations must be completed for each county to be served,”
    suggesting that the fourth calculation applies in every CON cases, not just in those where
    a CON has been issued to another provider within the past 12 months. Additionally,
    petitioners claim, albeit in an oblique fashion, that absent a threshold of 229 individuals to
    establish unmet need, the Standards would not meet the objectives set forth in West
    Virginia Code § 16-2D-1, particularly the “avoid[ance of] unnecessary duplication of
    health services.”
    We are unpersuaded that these scattershot arguments are sufficient to
    overcome the specific directive in the overview language of Section V(C) that
    “[c]alculation 4 involves an adjustment factor for the agencies receiving Certificate of
    Need approval in the previous 12 months to allow for their initiation and development of
    home health services[,]” and the specific directive in subsection V(C)(4) that “[t]his
    calculation is done only if there are agencies in the proposed county which received CON

    approval in the previous 12 months.” (Emphasis added). 20 We are further unpersuaded
    that the placement of the “Conclusion” in subsection (C)(4) in un-indented text, see supra
    note 19, has any significance. In this regard, we note that the “Calculation of the Actual
    Total County Home Health Utilization Rate,” set forth in subsection V(C)(1) of the
    Standards, is set up in a manner identical to V(C)(4): following an indented six-step
    analysis whose purpose is to determine whether a county’s home health utilization rate is
    below the state rate, we find the following, un-indented, line: “If yes, continue with the
    following. If no, an unmet need does not exist.” Likewise, we are unpersuaded that
    petitioners’ argument is supported by common sense, in light of the undisputed testimony
    that if an unmet need of 229 individuals were needed to support the issuance of a CON, ten
    counties in West Virginia would never be able to meet the 229 threshold.
    In addition, the petitioners give no weight at all to the undisputed fact that for
    at least 20 years, the Authority has consistently interpreted the 229 figure as an adjustment
    factor, not a threshold factor, and accordingly has consistently interpreted subsection
    V(C)(4) of the Standards to apply only in cases where another provider has received a CON
    within the 12 months preceding a new application. 21 In this regard, we have held that
    20
    As previously noted, because no virgule appears in these directives, we will not
    linger over petitioners’ complex linguistic argument that its appearance elsewhere in the
    Standards somehow transforms the word “adjustment” into “threshold.”
    21
    Petitioners put on evidence to show that the Authority’s predecessor, HCCRA,
    seemed to embrace petitioners’ view while the Standards were being developed, by affixing
    26
    [i]nconsistency is only one of many circumstances that
    this Court should consider in determining deference. The
    factors most often recognized by courts as to whether to defer
    to administrative interpretations were set out by Colin S. Diver
    in Statutory Interpretation in the Administrative State, 
    133 U. Pa. L. Rev. 549
    , 562 n. 95 (1985). He lists them as
    “(1) whether the agency construction was
    rendered contemporaneously with the statute's
    passage, ... (2) whether the agency’s construction
    is of longstanding application, ... (3) whether the
    agency has maintained its position consistently
    (even if infrequently), ... (4) whether the public
    has relied on the agency’s interpretation, ... (5)
    whether the interpretation involves a matter of
    ‘public controversy,’ ... (6) whether the
    interpretation is based on ‘expertise’ or involves
    a ‘technical and complex’ subject, ... (7) whether
    the agency has rulemaking authority, ... (8)
    whether agency action is necessary to set the
    statute in motion, ... (9) whether ... [the
    Legislature] was aware of the agency[‘s]
    interpretation and failed to repudiate it, ... and
    (10) whether the agency has expressly addressed
    the application of the statute to its proposed
    action[.]” (Citations omitted).

    Finally, with respect to petitioners’ intimation that the Authority’s
    interpretation of the Standards allows for the unnecessary duplication of home health
    services in counties such as Cabell, Wayne, and Preston, we note that there is no empirical
    evidence in the appendix record to support such a claim. Additionally, although the Preston
    to the draft Standards a sample calculation that treated 229 as a threshold figure. However,
    HCCRA somehow “omitted” ‒ whether intentionally or inadvertently ‒ putting that sample
    calculation into the final version of the Standards that was signed by the Governor.
    27
    Memorial petitioners attempted to show at the hearing before the Authority that the
    existence of a new home health provider in Preston County would result in some
    “poaching” of the Preston Memorial petitioners’ existing patients, and that United’s plan
    for providing services in Preston County was not cost-effective, the petitioners did not list
    these alleged errors, directly or indirectly, in an assignment of error. Therefore this Court
    will disregard them on appeal. See Rule 10(c)(3) of the West Virginia Rules of Appellate
    Procedure. 22
    Building on the preceding arguments, all of which analyze the language,
    placement, and punctuation of Section V(C) of the Standards through the lens of an English
    academician, petitioners next contend that in 2007, the Circuit Court of Mason County
    found, on facts materially similar to those in the instant consolidated cases, that the 229
    22
    This Court recently discussed the importance of assignments of error, cautioning
    that
    a petitioner’s presentation of an assignment of error allows a
    respondent to address the focused issue, confident that he did
    not fail to discern a determinative argument buried in
    petitioner’s prose. This courtesy is imperative to equitable
    function, averting the danger that the Court and respondent
    may discern different issues from a petitioner's lengthy, free-
    flowing argument. This benefit, in turn, inures to the petitioner,
    ensuring that a responsive pleading does not throw the appeal
    into an unexpected rabbit hole.

    (memorandum decision).

    figure for unmet need was a threshold that all CON applicants must meet, not just an
    adjustment factor to be applied where another provider had received a CON in the
    particular county within the past 12 months. Pleasant Valley Hosp., Inc. v. Fam. Home
    Health Plus, Inc., d/b/a Ohio Valley Home Health, Inc., No. 06-AA-20 (Cir. Ct. of Mason
    Cnty., Mar. 27, 2007), appeals denied, Nos. 073947 and 073948 (W. Va. Sup. Ct. Apr. 3,
    2008). We may dispose of this argument without extended discussion. First, to the extent
    petitioners are trying to claim that the Mason County case has precedential value because
    of this Court’s denial of the appeals therefrom, we have clearly held to the contrary: “This
    Court’s rejection of a petition for appeal is not a decision on the merits precluding all future
    consideration of the issues raised therein[.]” Syllabus, in part, Smith v. Hedrick, 
    181 W. Va. 394
    , 
    382 S.E.2d 588
     (1989). Second, petitioners have given this Court no principled
    basis on which to conclude that the analysis of the court in Pleasant Valley Hospital was
    any more cogent, insightful, or scholarly than the contrary analysis of the two courts in the
    cases below. Third, as is clear from the analysis herein, we disagree with the conclusion
    reached by the court in the Pleasant Valley Hospital case and disagree with petitioners’
    sweeping assertion that “the [court’s] interpretation of the Home Health Standards is the
    only correct interpretation.”
    The petitioners’ next argument is ostensibly about health planning and public
    policy considerations, but in reality is merely a compilation of online information which
    purports to demonstrate that there exists (a) a “precipitous expansion of services by new
    providers in twenty-five counties” in West Virginia, and (b) a disconnect between the
    29
    Authority’s standard for unmet need in home health services and its standard for unmet
    need in other areas of health care. 23 Our examination of the voluminous appendix record
    submitted by the parties demonstrates that no empirical data to support these contentions
    was submitted to the Authority at either the Amedisys petitioners’ public hearing or the
    Preston Memorial petitioners’ public hearing, and therefore none of it was considered by
    either the Office of Judges or the circuit courts. Further, at oral argument respondents’
    counsel stated categorically that the number of home health care service providers is far
    fewer than existed at the time the Standards were established in 1995, in large part because
    of the consolidation of smaller providers into large nationwide providers such as Amedisys.
    We need not resolve these factual disputes because it is a bedrock principle
    of appellate jurisprudence that “representations in an appellate brief do not constitute a part
    of the record on appeal.” Pearson v. Pearson, 
    200 W. Va. 139
    , 152, 
    488 S.E.2d 414
    , 427
    (1997) (Workman, J., dissenting) (citing Wilkinson v. Bowser, 
    199 W.Va. 92
    , 
    483 S.E.2d 92
     (1996)). And in any event, the Legislature has delegated matters involving public health
    to the Authority, see 
    id.
     § 16-2D-1 to -20, which has the institutional expertise needed to
    resolve difficult issues of public health and citizens’ access to public health services. In
    this regard, we have held that this Court’s review of an agency determination
    23
    Petitioners cite to internet sources for information on the Authority’s standards
    governing unmet need for computed tomography; cardiac surgery; hospice services;
    megavoltage radiation therapy; positron emission tomography; fixed magnetic resonance
    imaging; in-home personal care; intermediate care facilities for individuals with
    intellectual disabilities; and end stage renal disease.
    30
    must be performed with conscientious awareness of its limited
    nature. The enforced education into the intricacies of the
    problem before the agency is not designed to enable the court
    to become a superagency that can supplant the agency’s expert
    decision-maker. To the contrary, the court must give due
    deference to the agency’s ability to rely on its own developed
    expertise. The immersion in the evidence is designed solely to
    enable the court to determine whether the agency decision was
    rational and based on consideration of the relevant factors.
    Princeton Cmty. Hosp. v. State Health Plan., 
    174 W. Va. 558
    , 564, 
    328 S.E.2d 164
    , 171
    (1985) (citation omitted); cf. Appalachian Power, 195 W. Va. at 582, 
    466 S.E.2d at 433
    (“An inquiring court ‒ even a court empowered to conduct de novo review ‒ must examine
    a regulatory interpretation of a statute by standards that include appropriate deference to
    agency expertise and discretion.”). Given the Authority’s longstanding interpretation of
    the particular Standard at issue, Section V(C) and more specifically subsection V(C)(4),
    this Court will not presume to second-guess a policy which has only been challenged three
    times in 25 years – with only one “win” for the position espoused by the petitioners, a
    decision that has no precedential value since this Court denied the appeal therefrom
    pursuant to our prior practice. 24
    In consideration of the foregoing, we hold that where the State Health Plan
    Home Health Services Standards were promulgated by the West Virginia Health Care
    24
    The current Rules of Appellate Procedure were promulgated and adopted by this
    Court on October 19, 2010, and were effective December 1, 2010. The Clerk’s comments
    to Rule 21, Memorandum decisions, note that “[t]he ability to enter memorandum
    decisions ‒ rather than refusal orders under prior practice ‒ is at the core of the revised
    process: every appeal, unless dismissed, will result in a decision on the merits.”
    31
    Authority (formerly the West Virginia Health Care Cost Review Authority) pursuant to a
    legislative grant of authority, West Virginia Code §§ 16-2D-1 to -20 (2016 & Supp. 2020),
    authorized by the Governor, and formally adopted and given full force and effect by the
    Legislature, see id. § 16-2D-6(g), the longstanding, consistent interpretation of those
    Standards by the West Virginia Health Care Authority, being neither arbitrary nor
    capricious, is entitled to judicial deference pursuant to Chevron U.S.A., Inc. v. Natural
    Resources Defense Council, Inc., 
    467 U.S. 837
     (1984).
    Finally, the Amedisys petitioners contend that the Authority erred in granting
    a CON to Personal Touch because the data upon which the Section V(C) calculations were
    based was not “the most recent home health survey data” available. In this regard, Personal
    Touch utilized a methodology containing 2015 data, rather than utilizing 2017 data which
    had been collected and aggregated by the Authority from a 2018 survey and made public
    in or about June, 2018, prior to the date of Personal Touch’s application. Petitioners’ expert
    witness, Mr. Gibbs, testified that if the 2017 data had been utilized, the V(C) calculations
    would have demonstrated that the unmet need in Cabell County had actually declined to -
    195. In response, the respondents point out that it is the Authority, not the applicant, which
    performs the unmet need calculations, and that at the time the Personal Touch application
    was prepared and filed, the “2015 Home Health Care Methodology” was the most current
    methodology available. In that regard, the Authority states in its brief that even if the raw
    2017 data from the 2018 survey results was available in June, 2018, the “2017 Home Health
    32
    Need Methodology” was not available for use until December 8, 2018 ‒ months after the
    Personal Touch application had been submitted.
    Petitioners point to no statute, regulation, or case from this Court requiring an
    applicant to use available raw data rather than the data contained in the Authority’s most
    current “Hone Health Need Methodology.” Therefore, in accepting the calculations
    contained in the Personal Touch application, the agency cannot be said to “ha[ve] exceeded
    its constitutional or statutory authority or [to be] arbitrary or capricious[,]” Murray Energy,
    241 W. Va. at 631, 827 S.E.2d at 419, Syl. Pt. 6, in part.
    IV. Conclusion
    For the foregoing reasons, the decisions of the circuit court in No. 20-0308 and No.
    20-0401, consolidated for purposes of this appeal, are affirmed.
    Affirmed.
