    APPEALS FROM THE CIRCUIT COURT OF THE FIRST CIRCUIT
    JUNE 28, 2017
    RECKTENWALD, C.J., NAKAYAMA, AND WILSON, JJ.,
    CIRCUIT JUDGE CHANG, IN PLACE OF McKENNA, J., RECUSED,
    AND CIRCUIT JUDGE CRANDALL, IN PLACE OF POLLACK, J., RECUSED
    OPINION OF THE COURT BY RECKTENWALD, C.J.
    I.   Introduction
    This is a consolidated case involving substitute and
    part-time temporary teachers who were employed by the State of
    Hawai#i, Department of Education (“State” or “DOE”), and who
    claim they were underpaid by the State.
    Plaintiffs in the Garner case include more than 8,000
    2
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    substitute teachers (collectively “Garner Plaintiffs” or
    “substitute teachers”) who were paid on a per diem basis.
    Approximately half of the substitute teachers in Garner also
    worked in a part-time capacity for which they were paid hourly
    wages.
    During a prior interlocutory appeal in Garner, the
    Intermediate Court of Appeals (ICA) found that the circuit court
    properly ruled that the substitute teachers were underpaid and
    thus entitled to their per diem back wages pursuant to Hawai#i
    Revised Statutes (HRS) § 302A-624(e).        See Garner v. State, 122
    Hawai#i 150, 154-55, 
    223 P.3d 215
    , 219-20 (App. 2009) (Garner I).
    On remand, the circuit court ruled that the Plaintiff class
    included the substitute teachers who were paid hourly wages and
    calculated the amount of those wages due, and that Plaintiffs
    were entitled to interest on their hourly and per diem back wages
    under HRS § 103-10.
    In 2014, the State paid a partial settlement to Garner
    Plaintiffs in the amount of $14,031,874.70, which settled all per
    diem wage claims for the claim period from November 8, 2000
    through June 30, 2005.     The State continued to dispute its
    liability regarding the payment of the substitute teachers’
    hourly back wages, and whether the teachers are entitled to
    interest on their per diem and hourly wages.
    3
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    In 2015, the Circuit Court of the First Circuit
    (circuit court) entered final judgment in Garner, awarding hourly
    back wages to Plaintiffs who worked in a part-time capacity in
    the amount of $6,789,175.21 for the period from November 8, 2000
    through June 12, 2012.1     The circuit court also awarded interest
    on both the per diem and hourly back wages owed, in the amount of
    $13,542,186.74.
    Plaintiffs in the Kawashima case include approximately
    20,000 part-time temporary teachers (collectively “Kawashima
    Plaintiffs,” “part-time teachers” or “PTTs”) who were paid on an
    hourly basis.   Similar to the substitute teachers claiming hourly
    back wages in Garner, the PTTs in Kawashima argued that their
    hourly pay rate, which was set forth in School Code Regulation
    5203, was linked to the substitute teachers’ per diem pay rate
    under HRS § 302A-624(e).      Thus, based on the claimed linkage
    between Regulation 5203 and HRS § 302A-624(e), the PTTs argued
    that because the substitute teachers were underpaid, they too
    were underpaid.    The circuit court in Kawashima ruled that the
    PTTs were underpaid and entitled to hourly back wages in the
    amount of $24,026,329.52 for the period from February 20, 2004
    through June 12, 2012.2     In contrast to Garner, however, the
    1
    In Garner, the Honorable Karl K. Sakamoto presided.
    2
    In Kawashima, the Honorable Edwin C. Nacino presided.
    4
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    circuit court in Kawashima ruled that the PTTs were not entitled
    to interest on their unpaid hourly wages under HRS § 103-10.
    Nevertheless, the circuit court determined that had Plaintiffs
    been entitled to interest on their hourly back wages under HRS
    § 103-10, they would have been entitled to interest payments in
    the amount of $9,450,085.40.
    On appeal in Garner, the State argues that the circuit
    court erred in:       (1) determining that Plaintiffs’ claims for
    hourly back wages were “properly part of this case”; (2)
    determining that School Code Regulation 5203 is an HRS chapter 91
    rule; (3) granting summary judgment in favor of the substitute
    teachers on their hourly back wages contract claim; and (4)
    determining that the substitute teachers were entitled to
    interest on their hourly and per diem back wages under HRS § 103-
    10.
    On appeal in Kawashima, the State argues that the
    circuit court erred in:        (1) determining that School Code
    Regulation 5203 is an HRS chapter 91 rule; and (2) denying the
    State’s motion for summary judgment on the PTTs’ hourly back
    wages contract claim.        Kawashima Plaintiffs also cross-appealed
    the circuit court’s rulings, arguing that they are entitled to
    interest on their unpaid hourly wages under HRS § 103-10.
    This court accepted transfer of both Garner and
    5
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    Kawashima, and subsequently consolidated the cases.
    We conclude that Plaintiffs are not entitled to hourly
    back wages, or interest on any back wages (whether per diem or
    hourly) under HRS § 103-10.         Because we decide the case on the
    merits, we do not reach the question of whether the substitute
    teachers’ hourly back wages were properly within the scope of the
    Garner Plaintiffs’ claims.
    Therefore, the circuit court’s May 19, 2015 judgment in
    Garner is reversed and remanded for entry of judgment in favor of
    the State.     Additionally, the circuit court’s May 18, 2015
    judgment in Kawashima is affirmed in part to the extent that the
    circuit court determined that Plaintiffs are not entitled to
    interest under HRS § 103-10, and reversed on all other remaining
    grounds and remanded for entry of judgment in favor of the State.
    II.    Background
    We first provide essential background information
    regarding the compensation of substitute teachers and PTTs
    employed by the State.
    A.    Substitute Teachers’ Compensation
    In 1996, the legislature recodified the education
    statutes and enacted HRS § 302A-624(e) (Supp. 1997), which
    established the following per diem rate of pay for substitute
    teachers:
    6
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    (e) Effective July 1, 1996, the per diem rate for
    substitute teachers shall be based on the annual entry
    step salary rate established for a Class II teacher on
    the most current teachers’ salary schedule. The per
    diem rate shall be derived from the annual rate in
    accordance with the following formula:
    Per Diem Rate = Annual Salary Rate ÷ 12 months ÷ 21
    Average Working Days Per Month.
    A “Class II teacher” is defined as “any teacher who
    holds a certificate issued by the department based upon four
    acceptable years of college education and other requirements as
    may be established by the department[.]”3          HRS § 302A-618(b)(2)
    (Supp. 1997).
    3
    Subsection (e) remained in effect as enacted until 2005, when the
    legislature amended it as follows:
    (e) Effective July 1, 2005, the minimum hourly or
    minimum per diem rate for substitute teachers shall be
    determined by the legislature; provided that the
    department shall develop a classification and
    compensation schedule that is not restricted to the
    minimum compensation rates but may exceed them;
    provided further that any individual in class I, II or
    III who works less than a full seven-hour work day
    shall be compensated on a prorated, hourly basis as
    follows:
    (1) Class I: other individuals who do not possess a
    bachelor’s degree shall be compensated at a rate of
    not less than $119.80 for a full work day;
    (2) Class II: individuals with a bachelor’s degree
    shall be compensated at a rate of not less than $130
    for a full work day; and
    (3) Class III: department of education teachers, or
    licensed or highly qualified teachers, shall be
    compensated at a rate of not less than $140 for a full
    work day.
    HRS § 302A-624(e) (Supp. 2005).
    None of the issues in this appeal concern HRS § 302A-624(e) (Supp.
    2005), and all further references to HRS § 302A-624(e) refer to HRS § 302A-
    624(e) (Supp. 1997).
    7
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    B.    Part-Time Teachers’ Compensation
    Since at least 1945, the DOE has had a body of internal
    guidelines called the “School Code.”          In 1976, the Board of
    Education (BOE) adopted School Code Regulation 5203, which linked
    the hourly wage of PTTs to the per diem wage paid to substitute
    teachers.     Regulation 5203 provides:
    E.    Part-time Temporary Teachers (Academic and Non-
    Academic)
    EFFECTIVE SEPTEMBER 1, 1976:
    Pay rates for Part-time Temporary Teachers
    (Academic and Non-Academic) employed on an
    hourly basis shall be based on the most current
    Per Diem Rates established for Substitute
    Teachers as follows:
    Class I     Per Diem Rate for Substitute
    Teacher
    Class II    Per Diem Rate for Substitute
    Teacher
    Class III   Per Diem Rate for Substitute
    Teacher
    Hourly Rates shall be derived from Per Diem
    Rates in accordance with the following formula:
    *Hourly Rate = Per Diem Rate ÷ 6 average
    working hours per day
    The regulation remained unamended until 2005, when the
    first of a series of changes occurred.           In January 2005, the DOE
    issued a new version of the Regulation 5203, which stated,
    “Compensation for Part-time Temporary Teachers on an hourly basis
    shall be determined by the [DOE].”          In a July 2005 memorandum,
    Superintendent Patricia Hamamoto adjusted the pay rate of PTTs as
    follows:
    8
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    Beginning July 1, 2005, all employees hired as
    part-time teachers will be assigned to two classes.
    Compensation will be determined by the academic
    qualifications of the employee. The following is a
    breakdown of the classes:
    • Class A: Employees with a minimum of a
    Bachelor’s Degree from an accredited
    institution.
    Compensation Rate: $22.43 per hour
    • Class B: Employees with no Bachelor’s Degree.
    Compensation Rate: $20.67 per hour
    Payment for these employees will be retroactive to
    July 1, 2005.
    In 2006, the BOE retroactively ratified the
    Superintendent’s July 2005 memorandum establishing the PTTs’ pay
    rate.    In 2009, the DOE issued “Standard Practice Document SP
    5203” (SP 5203), which was intended to supersede Regulation 5203
    that was amended January 2005.        SP 5203 stated that compensation
    for PTTs “shall be determined by the Department.”            In 2012, the
    DOE adopted Hawai#i Administrative Rules (HAR) chapter 8-66
    (effective June 14, 2012) pursuant to HRS chapter 91’s rulemaking
    procedures, which provided compensation rates for part-time
    temporary teachers.4
    4
    HAR § 8-66-7 provides:
    Compensation classes. A part-time temporary teacher
    shall be assigned to a compensation class based on the
    academic qualifications of the individual. The two
    classes of compensation are:
    (1) Class A for part-time temporary teachers
    with a minimum of a bachelor’s degree from an
    accredited institution of higher learning; and
    (2) Class B for all part-time temporary teachers
    not included in Class A.

    C.    Garner Circuit Court Proceedings
    In 2002, Plaintiffs David Garner, Patricia Smith,
    Andrea Christie, and Allan Kliternick filed a class action
    complaint in the Circuit Court of the Second Circuit, claiming
    that the DOE failed to pay the substitute teachers’ wages
    mandated by HRS § 302A-624(e), and seeking back pay for the 2000-
    2001, 2001-2002, and 2002-2003 school years.5
    The circuit court certified the Plaintiff class in
    Garner to include:
    [a]ll persons who have served in position numbers
    75100, 75101, 75102, as identified on a DOE SF-5 as a
    substitute teacher for the Hawaii DOE at public
    schools of the State of Hawaii from November 8, 2000
    through the present.
    The class includes approximately 8,000 substitute
    teachers.     Approximately half of the substitute teachers in
    Garner also worked in a part-time capacity for which they were
    paid hourly wages, and argue that they are entitled to both their
    per diem back wages and hourly back wages.
    4
    (...continued)
    HAR § 8-66-8 provides:
    Compensation rates. The hourly rate for the classes
    of part-time temporary teachers are as follows:
    (1) Class A: $22.43 per hour; or
    (2) Class B: $20.67 per hour.
    5
    In 2003, the Garner lawsuit was transferred from   the Second
    Circuit to the First Circuit and assigned to then-Judge (now   Justice)
    Richard W. Pollack. The case was subsequently reassigned to    the Honorable
    Karen Ahn in 2004, and then reassigned to the Honorable Karl   K. Sakamoto in
    2008.
    10
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    In 2005, Plaintiffs Allan Kliternick, David Garner, Jo
    Jennifer Goldsmith, and David Hudson filed a similar class action
    complaint in Kliternick v. Hamamoto (Kliternick case), which
    covered the 2004-2005 school year.        Garner and Kliternick were
    consolidated (collectively, the “Garner” case).
    In Garner, Plaintiffs raised two claims for relief in
    their operative complaint, seeking monetary damages and
    injunctive relief for:     1) violation of HRS § 302A-624(e)
    (underpaying the substitute teachers); and (2) violation of
    contract rights (breach of obligation to pay teachers per diem
    rate under HRS § 302A-624(e)).       The State moved for summary
    judgment as to all claims and parties, and Garner Plaintiffs
    moved for partial summary judgment with respect to liability for
    damages for the period from November 8, 2000 to June 30, 2005.
    The circuit court granted in part and denied in part Garner
    Plaintiffs’ motion for partial summary judgment, ruling, inter
    alia, that the State violated its contractual obligation to pay
    the substitute teachers per diem wages prescribed by HRS § 302A-
    624(e).   However, the circuit court ruled that the State had
    sovereign immunity as to prejudgment interest, and thus denied
    Garner Plaintiffs any prejudgment interest.          The circuit court
    then authorized an interlocutory appeal from its summary judgment
    order.
    11
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    The ICA affirmed, inter alia, the circuit court’s
    determination that the DOE violated its obligation to pay the
    substitute teachers by failing to pay the per diem rate
    prescribed by HRS § 302A-624(e).         Garner I, 122 Hawai#i at 
    154, 223 P.3d at 219
    .    The ICA also ruled that: (1) pursuant to HRS §
    661-1,6 the substitute teachers’ claim for breach of contract
    damages was not barred by sovereign immunity; (2) HRS § 302A-
    624(e), as a pay mandating statute, provided an alternative basis
    for invoking jurisdiction under the “founded upon any statute”
    language in HRS § 661-1; and (3) HRS § 661-87 barred any award of
    6
    HRS § 661-1 (1993) (Jurisdiction) provides:
    The several circuit courts of the State and, except as
    otherwise provided by statute or rule, the several
    state district courts, subject to appeal as provided
    by law, shall have original jurisdiction to hear and
    determine the following matters, and, unless otherwise
    provided by law, shall determine all questions of fact
    involved without the intervention of a jury:
    (1) All claims against the State founded upon
    any statute of the State; upon any rule of an
    executive department; or upon any contract, expressed
    or implied, with the State, and all claims which may
    be referred to any such court by the legislature;
    provided that no action shall be maintained, nor shall
    any process issue against the State, based on any
    contract or any act of any state officer that the
    officer is not authorized to make or do by the laws of
    the State, nor upon any other cause of action than as
    herein set forth . . . .
    7
    HRS § 661-8 (1993) (Interest) provides:
    No interest shall be allowed on any claim up to the
    time of the rendition of judgment thereon by the
    court, unless upon a contract expressly stipulating
    for the payment of interest, or upon a refund of a
    payment into the “litigated claims fund” as provided
    by law.
    12
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    prejudgment interest under HRS § 478-2.8          
    Id. The ICA
    specifically rejected the State’s argument that the substitute
    teachers had assented to a lower rate of pay than required by HRS
    §302A-624(e), reasoning that it was part of the parties’
    agreement that the rate of pay was “subject to applicable State
    laws,” and the parties “could not contract to violate a law
    determining the rate of pay.”9       
    Id. at 170,
    223 P.3d at 235
    (citations omitted).
    On remand, the substitute teachers pursued a different
    theory regarding their interest claim and moved for an award of
    interest on their unpaid per diem wages pursuant to HRS § 103-10
    8
    HRS § 478-2 (1993) (Legal rate; computation) provides:
    When there is no express written contract fixing a
    different rate of interest, interest shall be allowed
    at the rate of ten per cent a year, except that, with
    respect to obligations of the State, interest shall be
    allowed at the prime rate for each calendar quarter
    but in no event shall exceed ten per cent a year, as
    follows:
    (1) For money due on any bond, bill, promissory
    note, or other instrument of writing, or for money
    lent, after it becomes due;
    (2) For money due on the settlement of accounts,
    from the day on which the balance is ascertained;
    (3) For money received to the use of another,
    from the date of a demand made; and
    (4) For money upon an open account, after sixty
    days from the date of the last item or transaction.
    As used in this section, “prime rate” means the prime
    rate as posted in the Wall Street Journal on the first
    business day of the month preceding the calendar
    quarter.
    9
    Both sides filed applications for writ of certiorari, and both
    applications were rejected.
    13
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    (1993).10   At a hearing on the motion, the circuit court
    explained that according to Garner I, the substitute teachers
    were unquestionably in a contractual relationship with the State,
    and that HRS § 103-10 was a “pertinent statute incorporated by
    the contractual relationship.”        Thus, the circuit court
    determined that HRS § 103-10 “constitute[d] a contract expressly
    stipulating for the payment of interest as required under [HRS §]
    661-8,” and concluded that Garner Plaintiffs were entitled to
    10
    HRS § 103-10 (1993) provides in relevant part:
    (a)   Any person who renders a proper statement for
    goods delivered or services performed, pursuant to
    contract, to any agency of the State or any county,
    shall be paid no later than thirty calendar days
    following receipt of the statement or satisfactory
    delivery of the goods or performance of the services.
    In the event circumstances prevent the paying agency
    from complying with this section, the person shall be
    entitled to interest from the paying agency on the
    principal amount remaining unpaid at a rate equal to
    the prime rate for each calendar quarter plus two per
    cent, commencing on the thirtieth day following
    receipt of the statement or satisfactory delivery of
    the goods or performance of the services, whichever is
    later, and ending on the date of the check. As used in
    this subsection, “prime rate” means the prime rate as
    posted in the Wall Street Journal on the first
    business day of the month preceding the calendar
    quarter.
    (b)   This section shall not apply in those cases
    where delay in payment is due to:
    (1)   A bona fide dispute between the State or
    any county and the contractor concerning the services
    or goods contracted for;
    (2)   A labor dispute;
    (3)   A power or mechanical failure;
    (4)   Fire;
    (5)   Acts of God; or
    (6)   Any similar circumstances beyond the
    control of the State or any county.
    14
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    interest on their per diem back pay under HRS § 103-10.11
    The State moved for a ruling as to the scope of the
    Garner Plaintiff class, and sought to preclude the Garner class
    members’ recovery for unpaid hourly wages, seeking to limit
    recovery to only per diem wages.           Garner Plaintiffs filed a
    counter motion, seeking to affirm the scope of the class, or in
    the alternative to amend the class definition or the complaint.
    The circuit court granted Garner Plaintiffs’ motion and denied
    the State’s motion, ruling that the class members were entitled
    to recover both per diem and hourly back wages.
    Garner Plaintiffs then sought summary judgment for
    hourly back wages owed and interest thereon under HRS § 103-10.
    The State filed a counter summary judgment motion.             During a
    hearing on both motions, the circuit court stated that in the
    “interest of comity,” it would follow the circuit court’s ruling
    in the Kawashima case, finding that Regulation 5203 has the same
    force and effect as law and is subject to HRS chapter 91.12               The
    circuit court also determined that HRS § 103-10 was incorporated
    into the parties’ contracts and awarded interest on the
    11
    The circuit court further stated that the HRS § 478-2 analysis in
    Garner I did not apply here, and applied only to situations in which there was
    an absence of an express contract, which was distinguishable from the instant
    case.

    II.D.

    substitute teachers’ hourly back wages.           The circuit court
    subsequently filed an order granting Garner Plaintiffs’ motion
    and denying the State’s motion, ruling that the substitute
    teachers who also worked in a part-time capacity were entitled to
    hourly back wages from November 8, 2000 until June 14, 2012 and
    interest thereon under HRS § 103-10.
    In 2014, the State paid a partial settlement to Garner
    Plaintiffs in the amount of $14,031,874.70, which settled all per
    diem wage claims for the claim period from November 8, 2000
    through June 30, 2005.       The State continued to dispute its
    liability regarding the payment of hourly back wages.
    On May 19, 2015, the circuit court entered final
    judgment, awarding $6,789,175.21 to the substitute teachers for
    their hourly back wages, and $13,542,186.74 for interest owed
    under HRS § 103-10 on the hourly and per diem back wages through
    May 18, 2015.
    D.    Kawashima Circuit Court Proceedings
    In 2006, Diane Kawashima filed a class action
    complaint, alleging that the DOE had underpaid all PTTs because
    DOE’s School Code Regulation 5203 linked the hourly pay rates of
    PTTs to the per diem pay rates for substitute teachers.13
    13
    On February 13, 2006, Kawashima filed a motion to intervene in the
    Garner case. Garner I, 122 Hawaii at 
    154, 223 P.3d at 219
    . On April 27,
    2006, the circuit court denied the motion. 
    Id. 16 ***
    FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    Kawashima argued that because the DOE underpaid the substitute
    teachers, it followed that the DOE underpaid the PTTs as well.
    Kawashima moved for class certification, and the
    circuit court granted the motion, appointing Kawashima as class
    representative for a certified class of:
    All persons employed by the State of Hawai#i
    Department of Education, who were paid according to
    the pay rates for Part-Time Teachers with or without a
    differential (excluding the class members in [the
    Garner and Kliternick cases]) at any time within the
    applicable statute of limitations.
    The Kawashima case was stayed pending resolution of the
    interlocutory appeal in the Garner case.           After the ICA issued
    its decision in Garner I, the stay was lifted.14            Kawashima
    Plaintiffs then filed a motion for summary judgment, arguing
    that:     (1) the DOE’s School Code Regulation 5203 expressly linked
    the hourly pay rate for PTTs to the most current per diem pay
    rate for substitute teachers, and because the State had underpaid
    the substitute teachers, the State had necessarily underpaid the
    PTTs; and (2) the DOE’s and BOE’s “litigation-driven” attempts to
    amend Regulation 5203 beginning in January 2005 were improper and
    ineffective.
    At the hearing on the motion, the circuit court
    determined that Regulation 5203 has the “same force and effect as
    law,” and is subject to HRS chapter 91.           The court also found
    14
    The Honorable Edwin C. Nacino presided from this point forward.
    17
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    that Regulation 5203 did not fall under the two exceptions of an
    HRS chapter 91 rule because it did not involve internal
    management or affect the private rights of the public.            The court
    reasoned that Regulation 5203 should have the same force and
    effect as law because it “in all shape and form, refers to [HRS
    §] 302A-624(e) with regards to how the part-time teachers should
    be paid.”    Accordingly, the circuit court granted Kawashima
    Plaintiffs’ motion for summary judgment.         Because the court
    determined that Regulation 5203 is an HRS chapter 91 rule, any
    amendments to Regulation 5203 would have had to be made in
    accordance with HRS chapter 91’s rulemaking processes, which was
    not completed until 2012 when the DOE adopted HAR chapter 8-66.
    However, if the court had determined the Regulation 5203 was not
    a rule, the DOE could have amended Regulation 5203 at any time,
    and it would not have been subject to HRS chapter 91’s
    restrictions.
    Kawashima Plaintiffs filed a motion for interest under
    HRS § 103-10 on the hourly unpaid wages, arguing that the circuit
    court’s ruling in Garner that awarded substitute teachers
    interest on their per diem back wages under HRS § 103-10 was
    persuasive.    The circuit court denied the motion without
    prejudice.    Kawashima Plaintiffs filed a renewed motion for
    interest, arguing that the circuit court’s ruling in Garner that
    18
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    the substitute teachers were entitled to interest on both their
    hourly and per diem back wages under HRS § 103-10 was persuasive.
    The circuit court denied Kawashima Plaintiffs’ renewed motion.
    Kawashima Plaintiffs filed a second renewed motion for summary
    judgment for interest, and the State filed a cross-motion for
    partial summary judgment as to interest.         At the hearing on the
    motions, the circuit court determined that HRS § 103-10 did not
    apply to Kawashima Plaintiffs, and that the purpose and intent of
    HRS § 103-10 “is to address goods and services being provided by
    independent contractors, small business people, [and] maybe
    persons in general [that are] not even considered a contractor
    but [are] providing a service or goods to the State.”            Thus, the
    circuit court granted the State’s motion and denied Kawashima
    Plaintiffs’ second renewed motion, ruling that as a matter of
    law, Kawashima Plaintiffs were not entitled to interest on their
    hourly back wages under HRS § 103-10.
    In 2015, Kawashima Plaintiffs moved for summary
    judgment to establish the amount of hourly back wages Plaintiffs
    were owed, and the interest thereon under HRS § 103-10 had they
    been entitled to it.     The circuit court granted Kawashima
    Plaintiffs’ motion, and on May 18, 2015, entered final judgment,
    establishing that Kawashima Plaintiffs were entitled to damages
    in the amount of $24,026,329.52 for their hourly back wages for
    19
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    the period from February 20, 2004 through June 12, 2012.               The
    circuit court also determined that had Plaintiffs been entitled
    to interest on their hourly unpaid wages under HRS § 103-10, they
    would have been entitled to $9,450,085.40 through May 6, 2015.
    E.     Garner Appeal
    The State argues on appeal that the circuit court erred
    in:    (1) determining that the substitute teachers’ hourly back
    wages were properly within the scope of Plaintiffs’ claims, (2)
    determining that Regulation 5203 is an HRS chapter 91 rule, (3)
    granting summary judgment in favor of the substitute teachers on
    their hourly back wages contract claim, and (4) determining that
    the substitute teachers were entitled to interest on their hourly
    and per diem back wages under HRS § 103-10.
    First, the State argues that the Garner Plaintiffs’
    claims did not include their hourly back wages, and that the
    trial court ignored prior rulings and the ICA’s decision in
    Garner I when adding these claims.           Second, the State argues that
    Regulation 5203 is not an HRS chapter 91 rule because it was not
    adopted pursuant to rulemaking procedures, and even if it was,
    the State employees’ wages are a matter of internal concern and
    should not be determined by rule.           Third, the State argues that
    the substitute teachers were paid the amount they contracted for,
    and that they do not have a valid contract claim for the alleged
    20
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    additional wages owed.       Fourth, the State argues that Garner
    Plaintiffs are not entitled interest under HRS § 103-10 because
    the ICA already ruled on that issue in Garner I and prejudgment
    interest is not allowed.
    In response, Garner Plaintiffs first argue that the
    class members who worked for both per diem and hourly wages are
    entitled to recover all their back wages because the class
    membership included teachers in all of their roles, the circuit
    court did not limit the scope of damages, and the State was given
    fair notice that hourly wages, as well as per diem wages, were in
    dispute.    Second, Garner Plaintiffs argue that they are entitled
    to wages mandated by Regulation 5203 because the State did not
    lawfully sever the link between Regulation 5203 and HRS § 302A-
    624 until June 2012 when it followed HRS chapter 91 rulemaking
    procedures.     Third, Garner Plaintiffs argue that with respect to
    their contracts, the State cannot ignore the law and must pay its
    employees lawfully prescribed rates of pay.            Fourth, Garner
    Plaintiffs argue that the circuit court had not previously
    addressed the issue of interest under HRS § 103-10, and that HRS
    § 103-10 is a “specific, targeted ‘pay-mandating’ immunity-
    waiving statute” that “creates a separate, enforceable waiver.”
    F.    Kawashima Appeal
    In Kawashima, the State raises similar contentions as
    21
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    in the Garner appeal.       In response, Kawashima Plaintiffs argue
    that the State cannot enter into or enforce contracts that are
    contrary to law, and that this issue was resolved in Garner I.
    Kawashima Plaintiffs also argue that the BOE had sole authority
    over the PTTs’ pay rates, and that it did not act in accordance
    with HRS chapter 91, HRS chapter 89C, and HRS § 302A-1112,15
    until June 2012 at the earliest.
    On cross-appeal, Kawashima Plaintiffs raise one issue:
    whether the circuit court erred in denying the PTTs interest on
    their unpaid hourly wages under HRS § 103-10.            Kawashima
    Plaintiffs argue that the State has no immunity against an award
    of interest under HRS § 103-10 because it is an “immunity-
    waiving, money-mandating statute,” and that it applies broadly to
    “persons” and “contractors.”        In response, the State argues that
    HRS § 103-10 is not applicable here because it applies only to
    contractors with claims covered by the Procurement Code.
    G.    Transfer Applications
    Kawashima and Garner Plaintiffs filed applications for
    transfer to this court, and we granted transfer in both cases.
    15
    HRS § 302A-1112 (1996) (Rules) provides:
    Subject to chapter 91, the board may adopt rules for
    the government of all teachers, educational officers,
    other personnel, and pupils, and for carrying out the
    transaction of its business.
    22
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    The cases were subsequently consolidated.
    III.    Standards of Review
    A.    Summary Judgment
    The appellate court reviews “the circuit court’s grant
    or denial of summary judgment de novo.”           Querubin v. Thronas, 107
    Hawai#i 48, 56, 
    109 P.3d 689
    , 697 (2005) (quoting Durette v.
    Aloha Plastic Recycling, Inc., 105 Hawai#i 490, 501, 
    100 P.3d 60
    ,
    71 (2004)).     Accordingly,
    [o]n appeal, an order of summary judgment is reviewed
    under the same standard applied by the circuit courts.
    Summary judgment is proper where the moving party
    demonstrates that there are no genuine issues of
    material fact and it is entitled to a judgment as a
    matter of law. In other words, summary judgment is
    appropriate if the pleadings, depositions, answers to
    interrogatories, and admissions on file, together with
    the affidavits, if any, show that there is no genuine
    issue of material fact and the moving party is
    entitled to a judgment as a matter of law.
    Iddings v. Mee-Lee, 82 Hawai#i 1, 5, 
    919 P.2d 263
    , 267 (1996);
    see also Hawai#i Rules of Civil Procedure (HRCP) Rule 56(c)
    (2000).16
    16
    HRCP Rule 56(c) provides, in relevant part:
    The judgment sought shall be rendered forthwith if the
    pleadings, depositions, answers to interrogatories,
    and admissions on file, together with the affidavits,
    if any, show that there is no genuine issue as to any
    material fact and that the moving party is entitled to
    a judgment as a matter of law. A summary judgment,
    interlocutory in character, may be rendered on the
    issue of liability alone although there is a genuine
    issue as to the amount of damages.
    23
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    B.    Statutory Interpretation
    “Statutory interpretation is a question of law
    reviewable de novo.”       First Ins. Co. of Hawaii v. A&B Props., 126
    Hawai#i 406, 414, 
    271 P.3d 1165
    , 1173 (2012) (quoting State v.
    Wheeler, 121 Hawai#i 383, 390, 
    219 P.3d 1170
    , 1177 (2009)
    (internal quotation marks omitted)).
    Our construction of statutes is guided by the following
    rules:
    First the fundamental starting point for
    statutory-interpretation is the language of the
    statute itself. Second, where the statutory language
    is plain and unambiguous, our sole duty is to give
    effect to its plain and obvious meaning. Third,
    implicit in the task of statutory construction is our
    foremost obligation to ascertain and give effect to
    the intention of the legislature, which is to be
    obtained primarily from the language contained in the
    statute itself. Fourth, when there is doubt,
    doubleness of meaning, or indistinctiveness or
    uncertainty of an expression used in a statute, an
    ambiguity exists.
    
    Id. (quotations and
    citations omitted).
    In construing an ambiguous statute, “[t]he meaning of
    the ambiguous words may be sought by examining the
    context, with which the ambiguous words, phrases, and
    sentences may be compared, in order to ascertain their
    true meaning.” Moreover, the courts may resort to
    extrinsic aids in determining legislative intent. One
    avenue is the use of legislative history as an
    interpretive tool.

    Infusion Assocs. v. Befitel, 114 Hawai#i 87, 91,

    ,
    530 (2007)).
    24
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    IV.   Discussion
    The issues presented on appeal include whether the
    circuit court erred in:     (1) finding that the Garner Plaintiffs’
    claims for hourly back wages were properly within the scope of
    the case; (2) finding that Regulation 5203 was an HRS chapter 91
    rule; (3) granting Plaintiffs summary judgment on their hourly
    back wages contract claims; (4) either granting interest to the
    substitute teachers in Garner on their hourly and per diem back
    wages, or denying interest to the PTTs in Kawashima on their
    hourly back wages.
    For the following reasons, we conclude that Regulation
    5203 is not an HRS chapter 91 rule, that it does not have the
    force and effect of law, and that it was not incorporated into
    Plaintiffs’ contracts.     Thus, Plaintiffs are not entitled to
    hourly back wages, and the circuit court erred in granting
    Plaintiffs summary judgment on their hourly back wages contract
    claims.   In addition, we conclude that HRS § 103-10 is not
    applicable here.    Therefore, Plaintiffs are not entitled to
    interest on their hourly and per diem back wages.           Because we
    decide this case on these grounds, we need not reach the issue of
    whether the substitute teachers’ hourly wages were properly part
    of the Garner case.
    25
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    A.    The Circuit Court Erred in Finding That Regulation 5203 Is
    an HRS Chapter 91 Rule
    The first issue that we must address is whether
    Regulation 5203 is a rule under HRS chapter 91.            If a regulation
    or procedure is determined to be a rule under HRS chapter 91, the
    state agency with the proper authority must follow the rulemaking
    procedures under HRS § 91-3 (2012) in order to adopt, amend or
    repeal the rule.      Thus, if Regulation 5203 is in fact a rule,
    then the DOE did not properly amend Regulation 5203 until 2012
    when it adopted HAR chapter 8-66 in accordance with HRS chapter
    91 processes, and the State would be liable for the PTTs’ hourly
    back wages.     However, if we determine Regulation 5203 is not a
    rule, then Regulation 5203 would be an internal policy that the
    DOE may amend at any time, and the State would not be liable for
    any hourly back wages.
    We conclude that Regulation 5203 is not a rule.             HRS §
    302A-1112 (1996) provides broad authority for the BOE to adopt
    rules subject to HRS chapter 91:
    Subject to chapter 91 the [BOE] may adopt rules for
    the government of all teachers, educational officers,
    and other personnel, and for the carrying out the
    transaction of its business.
    Under HRS § 91-1(4) (2012), a rule is defined as
    follows:
    “Rule” means each agency statement of general or
    particular applicability and future effect that
    implements, interprets, or prescribes law or policy,
    26
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    or describes the organization, procedure, or practice
    requirements of any agency. The term does not include
    regulations concerning only the internal management of
    an agency and not affecting private rights of or
    procedures available to the public, nor does the term
    include declaratory rulings issued pursuant to section
    91-8, nor intra-agency memoranda.
    Thus, the general definition of rule is a “statement of
    general or particular applicability and future effect that
    implements, interprets, or prescribes law or policy, or describes
    the organization, procedure, or practice requirements of any
    agency.”   Green Party of Hawaii v. Nago, 138 Hawai#i 228, 237, 
    378 P.3d 944
    , 953 (2016).     In Green Party, we concluded that the
    Office of Election’s procedure to determine the number of
    election ballots to be delivered to the precincts was a rule
    because it “meets the generality element of HRS § 91–1(4) as it
    is applied statewide for the ordering of ballots in every
    precinct,” and would also “operate in the future.”           
    Id. at 239-
    40, 378 P.3d at 955-56
    ; see also Nuuanu Valley Ass’n v. City &
    Cty. of Honolulu, 119 Hawai#i 90, 99-100, 
    194 P.3d 531
    , 540-41
    (2008) (determining that the Department of Planning and
    Permitting of the City and County of Honolulu’s “policy of
    refusing to publicly disclose . . . engineering reports prior to
    their approval” was a rule because it “affect[ed] the procedures
    available to the public” in that the files were “public records
    and may be examined upon request”) (internal brackets and
    quotation marks omitted) (citing HRS § 91-1(4))).           Here,
    27
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    Regulation 5203 meets the generality requirement of HRS § 91–1(4)
    because it applies statewide for all part-time teachers employed
    by the DOE, and also operates in the future because it prescribes
    prospective compensation for part-time teachers.
    Nevertheless, although Regulation 5203 meets the
    generality and future effect requirements of HRS § 91-1(4), it
    falls within an exception to the general definition of a rule.
    The exceptions to the general definition of rule include
    “regulations that concern only the internal management of an
    agency, and that do not affect private rights of or procedures
    available to the public.”       Green Party, 138 Hawai#i at 
    238, 378 P.3d at 954
    .    When considering whether a regulation concerns
    internal management, we consider “to whom the regulations are
    directed.    If the regulation is principally directed to its
    staff, then it is generally considered to be a matter of internal
    management.”    
    Id. (citations omitted).
           We stated that this
    approach is consistent with the legislative history of HRS § 91-
    1(4):
    It is intended by this definition of “rule” that
    regulations and policy prescribed and used by an
    agency principally directed to its staff and its
    operations are excluded from the definition. In this
    connection your Committee considers matters relating
    to the operation and management of state and county
    penal, correctional, welfare, educational, public
    health and mental health institutions, operation of
    the National Guard, the custodial management of the
    property of the state or county or of any agency
    primarily a matter of “internal management” as used in
    this definition.
    28
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    
    Id. (quoting H.
    Stand. Comm. Report No. 8, in 1961 House Journal,
    at 656).
    However, even if it is “determined that a regulation
    concerns only internal management of an agency, the exception
    will apply only if it is also determined that the regulation does
    not affect private rights or procedures available to the public.”
    
    Id. at 238–39,
    378 P.3d at 954–55 (stating that the exception was
    “intended to have a ‘limited scope’ because it only applies if it
    both relates to internal management of the agency and it does not
    affect private rights or public procedures”).
    This court has analyzed the applicability of the
    internal management exception several times.          At issue in Green
    Party was whether the Office of Election’s methodology and
    procedures in the 2012 election used to “(1) determine the number
    of election ballots to be delivered to the precincts, (2) request
    additional ballots when a precinct runs out of paper ballots, and
    (3) count the votes cast on a ballot for a precinct in which the
    voter is not entitled to vote,” constituted rules.           138 Hawai#i at
    
    230, 378 P.3d at 946
    .     This court concluded that the Office of
    Election’s methodology used to determine the number of election
    ballots to be delivered to the precincts was a “rule.”            
    Id. at 241,
    378 P.3d at 957.     We reasoned that the ballot order method
    “meets the generality element of HRS § 91–1(4) as it is applied
    29
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    statewide for the ordering of ballots in every precinct,” and
    also would “operate in the future.”           
    Id. at 239-
    40, 378 P.3d at
    955-56
    .     Regarding the exception, this court reasoned that,
    “because ballot shortages may result in the deprivation of the
    right to vote, the ballot order methodology does not qualify for
    the internal management exception to the definition of a ‘rule.’”
    
    Id. at 240,
    378 P.3d at 956.
    This court also concluded that the procedure for
    counting votes cast on a ballot for an incorrect precinct
    constituted a rule.        
    Id. at 243,
    378 P.3d at 959.        With respect
    to the internal management exception and the private rights of
    the public, this court reasoned that:
    [e]ven assuming that the procedure only concerned
    internal management of the agency, the method used by
    the Office of Elections would have a direct impact on
    the right to vote, including the private right of
    voters to have their votes counted. Such a policy
    would not only affect the private right to vote, but
    it could also impact the outcome of an election or
    require a new election.
    
    Id. In Aguiar
    v. Hawaii Housing Authority, 
    55 Haw. 478
    , 
    522 P.2d 1255
    (1974), this court determined that the Hawai#i Housing
    Authority’s (HHA) internal regulations, which set forth maximum
    income limits for continued occupancy by tenants in public
    housing and established a payment schedule, were rules.               
    Id. at 489-90,
    522 P.2d at 1262-63.         This court stated that the HHA’s
    30
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    amendment to its internal regulations “altered fundamentally the
    rental structure in public housing-its immediate result was to
    change the amount of rent paid by nearly every public housing
    tenant.”   
    Id. at 489,
    522 P.2d at 1262.        This court further
    stated that the amendments “setting maximum income limits for
    continued occupancy . . . determined every tenant’s eligibility
    to remain in public housing.”       
    Id. This court
    reasoned that
    these amendments plainly “‘affected’ in both a practical and a
    legal sense the ‘private rights’ not only of those tenants
    actually living in public housing but also those members of the
    public at large who were interested in becoming tenants.”             Id.;
    see also Aluli v. Lewin, 
    73 Haw. 56
    , 57, 59, 
    828 P.2d 802
    , 803-04
    (1992) (finding that the State Department of Health’s issuance of
    an “air pollution permit authorizing the construction and
    operation of [geothermal] wells” which would emit hydrogen
    sulfide was not in accordance with rulemaking, and that “[a]ir
    quality is an integral part of the quality of life and the public
    should have input in these matters”); Burk v. Sunn, 
    68 Haw. 80
    ,
    93, 
    705 P.2d 17
    , 27 (1985) (holding that the Department of Social
    Services and Housing’s policy with respect to prorating benefits
    under a food stamp program was a rule because it had a “direct
    impact on the rights of Food Stamp recipients”).
    In contrast, this court has held that bylaws or
    31
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    instructional procedures that do not affect “private rights of or
    procedures available to the public” are not rules.           See Rose v.
    Oba, 
    68 Haw. 422
    , 427, 
    717 P.2d 1029
    , 1032 (1986).           In Rose, a
    doctor contended that his privileges to practice medicine at the
    Hilo Hospital were “revoked pursuant to invalid procedures.”                
    Id. at 424,
    717 P.2d 1030
    .     The doctor argued that the “rules and
    regulations pursuant to which his privileges were revoked were
    not promulgated in accordance with the rule-making procedures
    . . . as enacted in [HRS] Chapter 91.”         
    Id. at 423,
    717 P.2d
    1030
    .   This court held that the regulations were not rules under
    HRS chapter 91 and that the:
    provisions for corrective action in the Hilo Hospital
    Bylaws do not affect private rights of or procedures
    available to the public. At best, they only
    indirectly affect the private rights of the public to
    the extent the public has an interest in
    qualifications of doctors practicing in public
    hospitals, and to the extent a patient’s choice of
    hospitals is reduced when his doctor’s privileges at a
    particular hospital are revoked.
    
    Id. at 427,
    717 P.2d at 1032.
    In Doe v. Chang, 
    58 Haw. 94
    , 
    564 P.2d 1271
    (1977), this
    court considered whether a manual of instructions for Department
    of Social Services and Housing personnel concerning welfare fraud
    investigations was subject to HRS Chapter 91 rulemaking
    requirements.    
    Id. at 95,
    564 P.2d at 1272-73.        This court held
    that the manual of instructions concerned “only its internal
    management” and did not “affect[] private rights of or procedures
    32
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    available to the public.”         
    Id. at 96,
    564 P.2d at 1273.        This
    court reasoned:
    The only persons purporting to be instructed or
    ordered thereby are the personnel of the department.
    The manual does not define the circumstances under
    which welfare recipients, or others not members of the
    department personnel, shall be granted of [sic] denied
    benefits. It does not command the public to do
    anything, prohibit the public from doing anything or
    declare the rights of the public in any respect. It
    does not make any procedures available to the public.
    We find it difficult to hypothesize a stronger example
    of the internal regulation contemplated by HRS [§]
    91-1(4).
    
    Id. Additionally, in
    In re Doe, 
    9 Haw. App. 406
    , 
    844 P.2d 679
    (1992), the ICA considered whether the field sobriety testing
    procedures established by the Hawai#i County Police Department
    [HCPD] were a rule.        
    Id. at 412,
    844 P.2d at 682-83.         The ICA
    reasoned that, like Chang, the procedures were:
    instructional in nature directed only to HCPD police
    officers. The procedures instructed the officers how
    to administer field sobriety tests to drivers
    reasonably believed to have been [driving under the
    influence], after they were properly stopped and
    ordered out of their cars. Also, although field
    sobriety tests intrude on drivers’ rights . . . HCPD’s
    field sobriety testing procedures are aimed at
    assuring the proper and correct methods of
    administering the tests to drivers.

    resources”).
    Here, the instant case is akin to Rose, Chang, and In
    re Doe, which involved regulations that focused on internal
    management of an agency and did not affect the private rights of
    members of the public.     Regulation 5203, like the regulations and
    policies in those aforementioned cases, falls squarely within the
    exception.    Regulation 5203 affects only the DOE’s internal
    management of its part-time teachers’ hourly pay rate.            Moreover,
    Regulation 5203 does not command members of the public to do
    anything or prohibit them from doing anything, nor does it
    declare the rights of members of the public or affect a procedure
    available to members of the public.         Rather, Regulation 5203 at
    best only indirectly affects private rights of members of the
    public to the extent that the public has an interest in knowing
    how teachers’ salaries are determined.         This interest, however,
    is not sufficient to remove Regulation 5203 from the exception
    here.
    The instant case is distinguishable from Green Party
    and Aguiar.    In those cases, the regulations affected the private
    rights of members of the public and implemented law or policy,
    and thus were found to be rules.         For example, in Green Party,
    the voting policies had a direct impact on the private right to
    vote and the general public’s right to have their vote counted in
    35
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    an election.     Green Party, 138 Hawai#i at 
    243, 378 P.3d at 959
    .
    Additionally, in Aguiar, the HHA’s regulations fundamentally
    altered the rental structure in public housing, which immediately
    changed the amount of rent for almost all public housing tenants
    and affected every tenant’s eligibility to remain in public
    housing.    Aguiar, 55 Haw. at 
    489, 522 P.2d at 1262
    .           Here,
    Regulation 5203 does not affect any private rights of the public
    or any procedures available to the public, and does not prescribe
    or implement law or policy.        Instead, Regulation 5203 affects
    only the internal management of a DOE part-time teachers’ pay
    rate.
    In sum, Regulation 5203 is not a rule under HRS chapter
    91, and thus was not required to be amended under HRS chapter
    91’s rulemaking procedures.        Therefore, the circuit court erred
    in finding that Regulation 5203 was a rule under HRS chapter 91.
    B.    The Circuit Court Erred in Granting Summary Judgment in
    Favor of Plaintiffs for Their Hourly Back Wages Contract
    Claims
    The State argues that because Regulation 5203 is not a
    rule, the Superintendent and the Board properly changed
    Regulation 5203, and the State is not liable for any alleged
    amounts owed after the change.         The State also argues that
    Regulation 5203 does not have the “force and effect of law and
    cannot be incorporated into the contract or substituted for the
    36
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    actual agreement of the parties.”        Garner and Kawashima
    Plaintiffs argue that the State cannot enter into or enforce
    contracts that are contrary to law, that it must pay its
    employees lawfully prescribed rates of pay, and that this issue
    was resolved in Garner I.
    In Garner I, the ICA found that the substitute teachers
    were entitled to their per diem back wages because as part of the
    parties’ agreement, the teachers’ rate of pay was “subject to
    applicable State laws,” and the parties “could not contract to
    violate a law determining the rate of pay.”          Garner I, 122
    Hawai#i at 
    170, 223 P.3d at 235
    (citations omitted).           If we
    accept arguendo Garner I’s threshold premise as true--that state
    law is incorporated into contracts–-and if we determine that
    Regulation 5203 has the force and effect of law, then Regulation
    5203 would be incorporated into the part-time teachers’
    contracts, and the State would be obligated to compensate the
    PTTs for hourly back wages.      Here, the part-time teachers’
    argument is one step removed from the premise of Garner I because
    the PTTs’ hourly pay rate is based on Regulation 5203, which
    links their compensation to the substitute teachers’ pay rate
    prescribed by state law.      In contrast, in Garner I, the
    substitute teachers’ pay rate is directly prescribed by statute
    under HRS § 302A-624(e).
    37
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    We conclude that Regulation 5203 does not have the
    force and effect of law, and that it is merely an internal policy
    that may be amended at any time.          Thus, Regulation 5203 is not
    incorporated into the part-time teachers’ contracts, Plaintiffs
    are not entitled to hourly back wages, and the circuit court
    erred in granting summary judgment in favor of Plaintiffs for
    their hourly back wages contract claims.
    HRS § 89C-1 (Supp. 2000), grants “appropriate
    authorities the necessary flexibility” to “adjust the wages,
    hours, benefits, and other terms and conditions of employment for
    their respective excluded public officers and employees.”              HRS
    § 89C-1.5 (Supp. 2000) defines “appropriate authority” to include
    the BOE.    Further, HRS § 89C-4 (Supp. 2000) sets forth guidelines
    for the BOE to adjust compensation for excluded employees exempt
    from civil service:      “Each appropriate authority shall determine
    the adjustments that are relevant for their respective excluded
    employees who are exempt from civil service in consideration of
    the compensation and benefit packages provided for other
    employees in comparable agencies.”17         Thus, HRS chapter 89C
    17
    At oral argument before this court, Plaintiffs argued that the
    State stipulated to a violation of HRS chapter 89C in the Kliternick
    stipulated order and amended judgment resolving all claims. Plaintiffs argued
    that their second claim for relief in Kliternick was a violation of HRS
    chapter 89C, and because the State stipulated on a “free-standing basis for
    all the damages,” this was a stipulation to a violation of HRS chapter 89C.
    However, the State did not explicitly stipulate to a violation of HRS chapter
    (continued...)
    38
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    clearly provides statutory authority for the BOE to adjust the
    wages of excluded employees, such as the part-time teachers here,
    in order to reflect the compensation rates of other comparable
    agencies.    However, while HRS chapter 89C provides the BOE
    authority and flexibility to adjust and amend the PTTs’ pay rate,
    it does not confer the force and effect of law onto the School
    Code Regulations.
    Additionally, HRS § 302A-1112 provides broad authority
    for the BOE to adopt rules subject to HRS chapter 91 for the
    “government of all teachers” and for the “carrying out of the
    transaction of its business.”        Similar to HRS chapter 89C, while
    HRS § 302A-1112 provides the authority for the BOE authority to
    adopt HRS chapter 91 rules, it does not establish a process
    separate from HRS chapter 91 that would give Regulation 5203 the
    force and effect of law.
    Further, HAR chapter 8-3 (2012) (Rules Applicable to
    Rulemaking Proceedings) does not provide authority to support the
    contention that Regulation 5203 has the force and effect of law.
    HAR chapter 8-3 applies to HRS chapter 91 rules and sets forth
    similar procedures to HRS chapter 91 that the BOE must follow
    17
    (...continued)
    89C in either the Kliternick stipulated order or amended judgment. Moreover,
    even if the State stipulated to a violation of HRS chapter 89C, HRS chapter
    89C does not support Plaintiffs’ contention that Regulation 5203 has the force
    and effect of law.
    39
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    when adopting and amending HRS chapter 91 rules.             Thus, HAR
    chapter 8-3 does not set forth a separate and distinct rulemaking
    process apart from HRS chapter 91, but instead, aligns the BOE’s
    procedures with HRS chapter 91.
    In conclusion, Regulation 5203 does not have the force
    and effect of law.      Rather, Regulation 5203 is an internal policy
    within the School Code that may be amended at any time.              While
    this court does not condone underpaying DOE teachers in violation
    of DOE policy, here, the applicable law does not provide a basis
    for the teachers’ entitlement to hourly back wages.             Thus,
    Regulation 5203 was not incorporated into the PTTs’ contracts,
    and the circuit court erred in granting summary judgment in favor
    of Plaintiffs for their hourly back wages contract claims.
    C.    Plaintiffs Are Not Entitled to Interest Under HRS § 103-10
    The State argues that the ICA has already ruled in
    Garner I that the teachers are not entitled to prejudgment
    interest, and that Plaintiffs cannot “ignore the law of the case”
    and “try again on another theory” and a “different statute on
    remand.”    The State also argues that because Plaintiffs prevailed
    only on the theory that there was an express contract between the
    teachers and the DOE, the only waiver of sovereign immunity as to
    that claim is under HRS chapter 661, and that the teachers are
    attempting to circumvent HRS § 661-8 by referring to HRS § 103-
    40
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    10.    The State argues that HRS § 661-8 provides that no pre-
    judgment interest is allowed except in certain instances, which
    are not present here, and that any doubt must be resolved in
    favor of the State.        Further, the State argues that HRS § 103-10
    does not apply because it should be applied only to contractors
    in “complex, high value claims” covered by the Procurement Code.
    Kawashima Plaintiffs argue that HRS § 661-8 does not
    preclude the right to interest because HRS § 103-10 is an
    “immunity-waiving, money-mandating statute” that confers a right
    to interest which “cannot be nullified because litigation ensues
    after an agency fails to pay.”          Kawashima Plaintiffs also argue
    that HRS § 103-10 applies broadly to anyone who provides services
    to the State under a contract, and that the complexity of the
    claim does not have a role in the application of the statute.
    The Garner circuit court found that the substitute
    teachers were entitled to interest on their per diem and hourly
    back wages under HRS § 103-10, reasoning that the contract
    between the parties incorporated applicable state law, including
    HRS § 103-10, and thus HRS § 103-10 “constitutes a contract
    expressly stipulating for the payment of interest as required
    under [HRS] 661-8.”
    In contrast, the Kawashima circuit court found that the
    PTTs were not entitled to interest on their hourly back wages
    41
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    under HRS § 103-10, agreeing with the State’s contentions that
    sovereign immunity under HRS § 661-8 applied, and that immunity
    is waived only if the contract “calls for prejudgment interest.”
    The Kawashima circuit court further determined that HRS § 103-10
    did not apply here, and that the purpose and intent of HRS § 103-
    10 was to “address goods and services being provided by
    independent contractors, small business people,” and “maybe
    persons in general” that are “not considered a contractor but
    [are] providing a service or goods to the State.”
    We begin our analysis by addressing the threshold
    question of whether the ICA’s holding in Garner I precludes the
    award of interest on another theory here.         We conclude that it
    does not.   The State’s reliance on Taylor-Rice v. State, 105
    Hawai#i 104, 
    94 P.3d 659
    (2004) to support its contention the ICA
    has already ruled that the teachers are not entitled to interest
    is misplaced.    In the underlying case, defendant Leigh and
    defendant-appellee, State of Hawai#i, were found to be “joint
    tortfeasors in an action arising from a single-car accident.”
    
    Id. at 106,
    94 P.3d at 661.      In its judgment, the circuit court
    found that “(1) the defendants were jointly and severally liable
    for damages, costs, and post-judgment interest and (2) Leigh was
    solely liable for pre-judgment interest.”         
    Id. This court
    determined that the plaintiffs did not “argue that the circuit
    42
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    court erred in failing to hold the State liable for pre-judgment
    interest.”    
    Id. Therefore, this
    court determined that “because
    the plaintiffs did not challenge the circuit court’s failure to
    hold the State liable for pre-judgment interest, the plaintiffs
    ‘must be held to acquiesce in’ the judgment and are precluded
    from now challenging it.”       
    Id. Here, the
    issue of whether the teachers are entitled to
    interest under HRS § 103-10 has not been foreclosed by the ICA’s
    Garner I decision, which was an interlocutory appeal.              While the
    ICA ruled in Garner I that the substitute teachers were not
    entitled to prejudgment interest under HRS §§ 661-8 and 478-2, it
    did not make a determination regarding whether the substitute
    teachers were entitled to interest on their back wages under HRS
    § 103-10.    Contrary to the argument of the State, that ruling is
    not the “law of the case” with regard to a completely distinct
    theory that was not raised or addressed in that interlocutory
    appeal.
    Turning to the merits, HRS chapter 661, which is
    entitled “Actions By And Against the State,” provides:
    No interest shall be allowed on any claim up to the
    time of the rendition of judgment thereon by the
    court, unless upon a contract expressly stipulating
    for the payment of interest, or upon a refund of a
    payment into the “litigated claims fund” as provided
    by law.
    HRS § 661-8.
    43
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    Here, the record does not support the conclusion that
    the teachers’ contracts expressly stipulated for the payment of
    interest.   The teachers’ contracts at issue, which consist of an
    “Application for Part-Time Temporary Teacher Position (Form 150)”
    and a “Payroll Understanding” form, do not expressly state that
    the teachers will be entitled to the payment of interest.
    However, Kawashima Plaintiffs further argue that HRS §
    661-8 does not preclude an award of interest because HRS § 103-10
    is an “immunity-waiving, money-mandating statute.”           This court
    has stated that statutory waivers of sovereign immunity will be
    strictly construed and that “a waiver of sovereign immunity must
    be unequivocally expressed in statutory text, and legislative
    history cannot supply a waiver that does not appear clearly in
    any statutory text,” nor can sovereign immunity be waived based
    on policy arguments.     Taylor-Rice, 105 Hawai#i at 110, 
    112, 94 P.3d at 663
    , 667.    Therefore, any ambiguity as to whether HRS
    § 103-10 expressly waives sovereign immunity regarding payment of
    interest should be construed in favor of the State.
    As set forth below, the plain language of HRS § 103-10
    is ambiguous as to whether it applies in the instant case.
    Accordingly, we refer to the Findings and Purpose section of Act
    292 (which was codified as HRS § 103-10), and HRS § 103-10’s
    legislative history, in order to resolve that ambiguity, and
    44
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    conclude that HRS § 103-10 does not apply here.
    HRS § 103-10 (Payment for goods and services) provides
    in pertinent part:
    (a)   Any person who renders a proper statement for
    goods delivered or services performed, pursuant to
    contract, to any agency of the State or any county,
    shall be paid no later than thirty calendar days
    following receipt of the statement or satisfactory
    delivery of the goods or performance of the services.
    In the event circumstances prevent the paying agency
    from complying with this section, the person shall be
    entitled to interest from the paying agency . . . .
    (b)   This section shall not apply in those cases
    where delay in payment is due to:
    (1)   A bona fide dispute between the State or
    any county and the contractor concerning the services
    or goods contracted for;
    (2)   A labor dispute;
    (3)   A power or mechanical failure;
    (4)   Fire;
    (5)   Acts of God; or
    (6)   Any similar circumstances beyond the
    control of the State or any county.
    Plaintiffs argue that HRS § 103-10 broadly applies to
    “any person,” and that the term “contractor” includes the
    teachers because the plain language definition of “contractor” is
    “anyone who provides services under a contract.”           Further, they
    suggest that the definition of “contractor” in HRS § 103D-104 (a
    “[c]ontractor means any person having a contract with a
    government body”), supports their argument that HRS § 103-10
    applies to the teachers in the instant case.
    However, other provisions in the relevant statutes
    suggest that HRS § 103-10 does not encompass claims for wages
    brought by State employees, such as those at issue here.
    45
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    Relevant to our interpretation of HRS § 103-10, HRS §103-1.5
    (1993) (Definitions) provides that:        “The definitions of chapter
    103D [(Hawaii Public Procurement Code)] shall apply to [HRS]
    chapter [103] unless the context clearly requires otherwise.”
    Under HRS § 103D-104 (1993) (Definitions), “contract” means “all
    types of agreements, regardless of what they may be called, for
    the procurement or disposal of goods or services, or for
    construction.”    Also pursuant to HRS § 103D-104, “procurement”
    means:
    buying, purchasing, renting, leasing, or otherwise
    acquiring any good, service, or construction. The
    term also includes all functions that pertain to the
    obtaining of any good, service, or construction,
    including description of requirements, selection and
    solicitation of sources, preparation and award of
    contracts, and all phases of contract administration.
    Thus, the plain language of HRS § 103-10 and the
    applicable definitions under HRS § 103D-104 indicate that the
    type of contract referred to in HRS § 103-10 includes “agreements
    . . . for the procurement or disposal of goods or services, or
    for construction.”    Applying those provisions here, it appears
    that the teachers’ contracts are not agreements for the
    procurement of goods or services as provided for in HRS § 103D-
    104 and the Procurement Code.       The teachers are not selling goods
    or services, but rather are being compensated as employees in
    accordance with their contracts with the State.          Under this
    interpretation, the teachers’ contracts would not be the type of
    46
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    contracts governed by HRS § 103-10.
    Due to the ambiguity in the plain language of HRS
    § 103-10 and these related provisions, we turn to the Findings
    and Purpose section of Act 292, which was later codified as HRS
    § 103-10, for guidance.     See Poe v. Haw. Labor Relations Bd., 97
    Hawai#i 528, 540, 
    40 P.3d 930
    , 942 (2002) (determining that
    statements of findings and policy may be used to clarify
    ambiguities as a “guide for determining legislative intent and
    purpose”).   The Findings and Purpose section supports the
    conclusion that HRS § 103-10 does not apply to the teachers in
    the instant case.    The section reads as follows:
    SECTION 1. Findings and Purpose. The legislature
    finds that a substantial number of contractors selling
    goods and services to the state and county governments
    must frequently wait 90 to 120 or more days to receive
    payment. The purpose of this Act is to require prompt
    payment on government contracts.
    1967 Haw. Sess. Laws Act 292, § 1 at 464.
    Thus, the Findings and Purpose section of Act 292
    indicates that the legislature intended HRS § 103-10 to be
    applied to “contractors selling goods and services.” (Emphasis
    added.)   Plaintiffs are not “contractors” who are selling “goods
    and services,” but rather are employees of the State.              If the
    legislature intended HRS § 103-10 to apply to any government
    employee, such as the teachers in the instant case, the
    legislature could have explicitly stated that in the plain
    47
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    language of HRS § 103-10.      However, the legislature did not
    provide any statutory language that explicitly makes HRS § 103-10
    applicable to the type of contracts in this case.
    Further, the legislative history also supports the
    interpretation that HRS § 103-10 was not intended to be applied
    to the teachers’ contracts at issue in the instant case.            With
    respect to HRS § 103-10, the Senate’s Federal-State-County
    Relations and Government Efficiency Committee stated that:
    The purpose of this bill is to require reasonably
    prompt payments by the state to contractors for goods
    delivered or services rendered and to require the
    payment of interest at the rate of one-half of one
    percent per month on balances unpaid within a
    prescribed period.
    Under present conditions, many [businesspersons]
    providing goods and services to State agencies have
    had to wait between 90 to 120 days after presentation
    of invoices before receiving payment.
    S. Stand. Comm. Rep. No. 663, in 1967 Senate Journal, at 1152.
    The teachers here are not “businesspersons” who provide
    goods and services to State agencies.        Instead, the teachers are
    government employees who are working pursuant to employment
    contracts with the State.
    In sum, both the Findings and Purpose section in Act
    292 and the relevant legislative history support the conclusion
    that HRS § 103-10 does not apply to Plaintiffs’ claims here.
    Moreover, as noted above, any ambiguity concerning a waiver of
    sovereign immunity should be construed in favor of the State.
    48
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    Accordingly, Plaintiffs are not entitled to interest on their
    back wages.
    V.   Conclusion
    In sum, the circuit court in both Kawashima and Garner
    erred in:   (1) determining that Regulation 5203 is an HRS chapter
    91 rule, and (2) granting summary judgment in favor of Plaintiffs
    for their hourly back wages contract claims.          In Garner, the
    circuit court further erred by finding that Plaintiffs were
    entitled to interest on their per diem and hourly back wages
    under HRS § 103-10.
    For the foregoing reasons, the circuit court’s May 19,
    2015 judgment in Garner is reversed and remanded for entry of
    judgment in favor of the State.       Additionally, circuit court’s
    May 18, 2015 judgment in Kawashima is affirmed in part to the
    extent that the circuit court determined that Plaintiffs are not
    entitled to interest under HRS § 103-10, and reversed on all
    other remaining grounds and remanded for entry of judgment in
    favor of the State.
