    N.C. DEPARTMENT OF STATE TREASURER, RETIREMENT SYSTEMS
    DIVISION, Defendant.
    Appeal by Plaintiffs from orders entered 9 July 2020 by Judge Paul C.

    ¶1           Deborah Sink Moss and Carla Shuford (collectively, “Plaintiffs”) appeal from
    orders entered on July 9, 2020, 1) granting Defendant’s motion to dismiss and 2)
    affirming the administrative law judge’s final decisions. On appeal, Plaintiffs allege
    the trial court erred by granting Defendant’s motion to dismiss and denying their

    Opinion of the Court
    petition for judicial review. After a careful review of the record and applicable law,
    we affirm the orders of the trial court.
    I.    Factual and Procedural Background
    ¶2         When Plaintiff Shuford was 15 years old she was diagnosed with osteogenic
    sarcoma and a tumor in her left leg. As a result, her left leg was amputated. On
    March 8, 1982, Plaintiff Shuford began working in an administrative position at the
    University of North Carolina. While at the University of North Carolina, Plaintiff
    Shuford was hospitalized due to post-traumatic stress issues relating to the loss of
    her leg and her physical disabilities. On August 23, 1988, she applied for short-term
    disability and received approval shortly thereafter.      On June 15, 1989, Plaintiff
    Shuford applied for long-term disability and was approved for long-term disability
    benefits retroactive to August 15, 1988.
    ¶3         On August 18, 1986, Plaintiff Moss worked as a teacher for the Wake County
    Public School Systems. Plaintiff Moss was given credit for 10 years of prior work
    experience. From November 1988 to December 1989, Plaintiff Moss was in three
    separate automobile accidents which resulted in injuries that caused her to
    experience pain while teaching. Subsequently, Plaintiff Moss was diagnosed with
    depression and stress from these car accidents. On April 17, 1990, she applied for
    short-term disability and was approved shortly thereafter. She then applied for long-

    2022-NCCOA-206
    Opinion of the Court
    term disability benefits on April 21, 1991 and was approved on June 11, 1991.
    ¶4         Each Plaintiff receives Transitional Disability Benefits from the North
    Carolina   Department      of   State   Treasurer,        Retirement   Systems   Division
    (“Defendant”). Under the terms of North Carolina’s Transitional Disability Benefits,
    disability payments are reduced by the gross amount of Social Security Disability
    benefits to which a person is entitled. As Social Security Disability benefits increase
    due to cost of living adjustments, the Plaintiffs’ disability payments from Defendant
    are reduced accordingly.
    ¶5         In 2017, Defendant discovered a programming error which failed to account for
    cost of living increases to Plaintiffs’ Social Security benefits. As a result, Defendant’s
    payments of benefits to individuals within the transitional disability group had been
    overpaid since 2006. Following this discovery, Defendant calculated the amount
    Plaintiffs should have received and accordingly reduced Plaintiffs’ monthly benefit
    payment amounts to offset the previously overpaid amount.
    ¶6         In 2017, Defendant informed Plaintiff Moss that she owed $13,235.00 in
    overpayments and informed Plaintiff Shuford that she owed $19,702.00 in
    overpayments. Defendant then reduced the amounts of Plaintiffs’ monthly disability
    benefits in order to recoup the overpayments.
    ¶7         Plaintiffs Moss and Shuford each filed a petition with the Office of
    Administrative Hearings (“OAH”) in December 2017, challenging the reduction in
    MOSS V. N.C. DEP’T OF STATE TREASURER
    2022-NCCOA-206
    Opinion of the Court
    their disability payments. Due to similar facts and legal issues, Plaintiffs’ cases were
    consolidated on January 2, 2018. The OAH held separate hearings for each Plaintiff.
    ¶8         On October 9, 2018, Plaintiff Moss’s case was heard by the administrative law
    judge, and on October 9 and 15, 2018, Plaintiff Shuford’s case was heard by the
    administrative law judge. At the hearing, Plaintiff Shuford offered her bank account
    statements and a spreadsheet as evidence of Defendant’s miscalculation of her
    benefits. At the conclusion of each hearing, Defendant made a Rule 41(b) motion for
    involuntary dismissal after the evidence was presented for Plaintiff Moss and
    Plaintiff Shuford.
    ¶9         On December 17, 2018, the administrative law judge issued final decisions in
    favor of Defendant and dismissed Plaintiffs’ cases with prejudice. Although Plaintiff
    Shuford had proffered her bank account statements at her hearing, the
    administrative law judge found they were “insufficient evidence to prove that her
    gross . . . [Social Security] Benefits differed from Respondent’s accounting.”      The
    administrative law judge further held that disability benefit overpayments were
    State property, not Plaintiffs’ personal property.        The administrative law judge
    concluded Plaintiffs (1) offered insufficient evidence to prove that the overpayment
    calculations were incorrect; (2) knew Social Security disability payments were to be
    deducted from their payments under the Transitional Disability Benefits; and (3)
    failed to prove Defendant substantially prejudiced their rights.

    2022-NCCOA-206
    Opinion of the Court
    ¶ 10         On January 16, 2019, Plaintiffs filed petitions in Wake County Superior Court
    for judicial review of the OAH Decisions, asserting both errors of law and fact.
    Defendant filed a motion to dismiss. On July 9, 2020, the Superior Court entered an
    order granting Defendant’s motion to dismiss and entered another order affirming
    the OAH Decisions. From entry of these two orders, Plaintiffs now appeal.
    II.     Discussion
    ¶ 11         Plaintiffs raise multiple issues on appeal; each will be addressed in turn.
    A. Motion to Dismiss
    ¶ 12         Plaintiffs first argue the trial court erred by granting Defendant’s motion to
    dismiss because Plaintiffs had established valid claims for breach of contract. We
    disagree.
    ¶ 13         We begin our review by noting a motion to dismiss is reviewed de novo.

    , 414, 
    813 S.E.2d 649
    , 654 (2018). Here,
    the Superior Court granted Defendant’s motion to dismiss under both Rule 12(b)(1)
    and 12(b)(6).
    1. 12(b)(6) Motion
    ¶ 14         Turning first to Rule 12(b)(6), a Rule 12(b)(6) motion to dismiss “tests the legal
    sufficiency of the complaint . . . .” Isenhour v. Hutto,

    Opinion of the Court
    N.C. 438, 442, 
    444 S.E.2d 423
    , 425 (1994)). “When reviewing the denial of a motion
    to dismiss pursuant to Rule 12(b)(6), the factual allegations in plaintiff’s complaint
    are treated as true.”

    448 S.E.2d 115
    , 116 (1994)).
    ¶ 15         A Rule 12(b)(6) motion reviews whether “as a matter of law, the allegations of
    the complaint, treated as true, are sufficient to state a claim upon which relief can be
    granted under some [recognized] legal theory.” Forsyth Memorial Hosp.,

    ,
    692, 
    403 S.E.2d 469
    , 471 (1991). “The complaint must be liberally construed, and the
    court should not dismiss the complaint unless it appears beyond a doubt that the
    plaintiff could not prove any set of facts to support his claim which would entitle him
    to relief.” Block v. County of Person, 
    141 N.C. App. 273

    649 (1988) (“A claim should be dismissed under Rule 12(b)(6) where it appears that
    the plaintiff is entitled to no relief under any statement of facts which could be
    proven.”).
    ¶ 16         Turning to Plaintiff’s argument that they had established valid claims for
    breach of contract, the elements for a breach of contract claim are the existence of a
    valid contract and a breach of the terms therein. Supplee v. Miller-Motte Bus. Coll.,
    Inc.,

    Opinion of the Court
    App. 19, 26, 
    530 S.E.2d 838
    , 843 (2000).
    ¶ 17         The relationship between State employees and the long-term disability system
    is contractual in nature. See Wells v. Consolidated Judicial Retirement Sys., 
    136 N.C. App. 671
    , 673, 
    526 S.E.2d 486
    , 488 (2000).         The long-term disability system is
    governed by Article 6 Chapter 135 of the North Carolina General Statutes. 
    N.C. Gen. Stat. § 135-100
    (a) (2021). Chapter 135 was enacted in 1987 and became effective on
    January 1, 1988. An Act to Make Appropriations for Current Operations of State
    Departments, Institutions, and Agencies, and For Other Purposes Except For Aid to
    Certain Governmental and Nongovernmental Units, ch. 738, § 29(r), 1987 N.C.
    Session Laws 1354, 1392. The contractual right to long-term disability benefits vests
    after “five or more years of membership service.” 
    N.C. Gen. Stat. § 135-106
    (a) (1988).
    However, a transitional provision provides an opportunity for employees who were
    employed at the time of Chapter 135’s enactment to receive disability benefits despite
    having less than five years of membership service:
    Any participant in service as of the date of ratification of
    this Article and who becomes disabled after one year of
    membership service will be eligible for all benefits provided
    under this Article notwithstanding the requirement of five
    years’ membership service to receive the long-term benefit;
    provided, however, any beneficiary who receive[s] benefits
    as a result of this transition provision before completing
    five years of membership service shall receive lifetime
    benefits in lieu of service accruals under the Retirement
    System as otherwise provided in [N.C.] G[en]. S[tat]. [§]
    135-4(y).
    MOSS V. N.C. DEP’T OF STATE TREASURER
    2022-NCCOA-206
    Opinion of the Court
    
    N.C. Gen. Stat. § 135-112
    (a) (1988).
    ¶ 18            Here, Plaintiffs were both employed as teachers for the State for at least one
    year, and thus, Plaintiffs qualified for long-term disability benefits. To the extent
    Plaintiffs and Defendant differ as to whether Plaintiffs were vested beneficiaries of
    the Teachers’ & State Employees’ Retirement System, or only in the transitional
    disability group per Section 135-112(a), we need not reach the merits of this
    argument. In the case sub judice, Plaintiffs only challenge Defendant’s right to
    recoup disability benefits. Thus, whether Plaintiffs were vested beneficiaries or not,
    Plaintiffs were still eligible for, and indeed received, disability payments under
    Chapter 135. These disability payments, in turn, are governed by the statutory
    requirements within Chapter 135. See Wells, 
    136 N.C. App. at 673
    , 
    526 S.E.2d at 488
    .
    ¶ 19            Under 
    N.C. Gen. Stat. § 135-106
    (b), the amount of long-term disability benefits
    received were supposed to be offset dollar-for-dollar by the Social Security Disability
    benefit for which Plaintiffs would otherwise be eligible. 
    N.C. Gen. Stat. § 106
    (b)
    (1988). Additionally, each contract contained a recoupment provision pursuant to
    N.C. Gen. Stat § 135-9. When Chapter 135 became effective in 1988, Section 135-9(b)
    stated
    [n]otwithstanding any provisions to the contrary, any
    overpayment of benefits to a member in a state-
    administered retirement system or the former Disability
    MOSS V. N.C. DEP’T OF STATE TREASURER
    2022-NCCOA-206
    Opinion of the Court
    Salary Continuation Plan or the Disability Income Plan of
    North Carolina may be offset against any retirement
    allowance, return of contributions or any other right
    accruing under this Chapter to the same person, the
    person’s estate, or designated beneficiary.
    
    N.C. Gen. Stat. § 135-9
    (b) (1988) (emphasis added). See 
    N.C. Gen. Stat. § 143
    -
    64.80(a). At the time of Plaintiffs’ hearings in 2018, our General Assembly had
    amended the language of Section 135-9(b) so that it read,
    [n]otwithstanding any provisions to the contrary, any
    overpayment of benefits or erroneous payments to a member
    in a State-administered retirement system or the former
    Disability Salary Continuation Plan or the Disability
    Income Plan of North Carolina, including any benefits paid
    to, or State Health Plan premiums or claims paid on behalf
    of, any member or beneficiary who is later determined to
    have been ineligible for those benefits or unentitled to
    those amounts, may be offset against any retirement
    allowance, return of contributions or any other right
    accruing under this Chapter to the same person, the
    person’s estate, or designated beneficiary.
    
    N.C. Gen. Stat. § 135-9
    (b) (2018) (emphasis added).
    ¶ 20         Moreover, the State has a duty under Section 143-64.80 to pursue the
    recoupment of any overpayment: “No State department, agency, or institution, or
    other State-funded entity may forgive repayment of an overpayment of State funds,
    but shall have a duty to pursue the repayment of State funds by all lawful means
    available, including the filing of a civil action in the General Court of Justice.” 
    N.C. Gen. Stat. § 143-64.80
    (b) (2018). The plain language of Section 135-9 in both 1988
    MOSS V. N.C. DEP’T OF STATE TREASURER
    2022-NCCOA-206
    Opinion of the Court
    and 2018 required the State to recoup any overpayments resulting from disability
    payments.     In other words, the statutory terms of Plaintiff Moss and Plaintiff
    Shuford’s right to receive disability payments included a recoupment clause which
    mandated Defendant to seek reimbursement from any overpayment.
    ¶ 21         Although we sympathize with the financial difficulties faced by Plaintiffs due
    to Defendant’s error, Plaintiffs’ statutory right to disability benefits also mandates
    the Defendant to seek recoupment of overpayments. See 
    N.C. Gen. Stat. § 135-9
    (b)
    (2018).    Plaintiffs’ argument that Defendant’s lawful action under the terms of
    Chapter 135 constitutes a breach of contract fails because Defendant had “a duty to
    pursue the repayment of State funds by all lawful means available.” § 143-64.80(b).
    Therefore, we hold the trial court did not err by granting Defendant’s motions to
    dismiss.
    2. 12(b)(1) Motion
    ¶ 22         Plaintiffs next argue the trial court erred by granting Defendant’s motion to
    dismiss under Rule 12(b)(1). A trial court grants a motion to dismiss pursuant to
    Rule 12(b)(1) when the court lacks jurisdiction over a subject matter. N.C. Gen. Stat.
    § 1A-1, Rule 12(b)(1) (2021). A party, or the court on its own, may assert lack of
    jurisdiction. Dale v. Lattimore, 
    12 N.C. App. 348
    , 352, 
    183 S.E.2d 417
    , 419 (1971).
    “The filing of a motion to dismiss under Rule 12(b)(1) does not raise an issue of fact[,]
    [i]t challenges the jurisdiction of the court over the subject matter.”        Journeys
    MOSS V. N.C. DEP’T OF STATE TREASURER
    2022-NCCOA-206
    Opinion of the Court
    International, Inc. v. Corbett, 
    53 N.C. App. 124
    , 125, 
    280 S.E.2d 5
    , 6 (1981). A Rule
    12(b)(1) motion may not be viewed in the same manner as a Rule 12(b)(6) motion
    because under Rule 12(b)(1) “matters outside the pleadings[] . . . may be considered
    and weighed by the court in determining the existence of jurisdiction over the subject
    matter.” Tart v. Walker, 
    38 N.C. App. 500
    , 502, 
    248 S.E.2d 736
    , 737 (1978).
    ¶ 23         Here, Plaintiffs specifically contend that Defendant waived the defense of
    sovereign immunity when it entered into a contract with Plaintiffs. See Guthrie v.
    North Carolina State Ports Authority, 
    307 N.C. 522
    , 535, 
    299 S.E.2d 618
    , 625 (1983)
    (“Sovereign immunity is a legal principle which states in its broadest terms that the
    sovereign will not be subject to any form of judicial action without its express
    consent.”). However, because the trial court properly granted Defendant’s motion to
    dismiss under 12(b)(6) we need not address Plaintiffs’ argument regarding 12(b)(1).
    B. Plaintiffs’ Petition for Judicial Review
    ¶ 24         Next, Plaintiffs contend the trial court erred by affirming the administrative
    law judge’s decisions. “When the trial court exercises judicial review over an agency’s
    final decision, it acts in the capacity of an appellate court.” N.C. Dep’t of Env’t &
    Natural Res. v. Carroll,

    MOSS V. N.C. DEP’T OF STATE TREASURER
    2022-NCCOA-206
    Opinion of the Court
    (1999)).
    ¶ 25         Under N.C. Gen. Stat. § 150B-51, the reviewing court may affirm or remand a
    final decision. N.C. Gen. Stat. § 150B-51(b) (2021). The reviewing court may also
    “reverse or modify the decision if the substantial rights of the petitioners may have
    been prejudiced because the findings, inferences, conclusions, or decisions are:” 1) A
    “violation of constitutional provisions”; 2) an “excess of the statutory authority or
    jurisdiction of the agency or administrative judge”; 3) an “unlawful procedure”; or 4)
    “[a]ffected by other error of law . . . .” § 150B-51(b)(1)-(4). If a petitioner alleges any
    of the above has been violated, the reviewing court must apply a de novo standard of
    review. § 150B-51(c). However, if a reviewing court is determining whether the
    findings, inferences, conclusions, or decisions are “[u]nsupported by substantial
    evidence admissible under G.S. 150B-29(a), 150B-30, or 150B-31 in view of the entire
    record as submitted” or “[a]rbitrary, capricious, or an abuse of discretion,” a whole
    record standard of review is to be applied. § 150B-51(b)(5)-(6), (c).
    ¶ 26         When this Court reviews an appeal from a superior court which either affirmed
    or reversed an administrative agency’s decision, we review for two factors: “(1)
    whether the superior court applied the appropriate standard of review and, if so, (2)
    whether the superior court properly applied this standard.” Mayo v. N.C. State Univ.,

    Opinion of the Court
    (2005).
    1. Bank Account Statements
    ¶ 27         Plaintiffs initially allege the administrative law judge’s decisions are not
    supported by competent evidence because they did not consider Plaintiff Shuford’s
    financial records. Plaintiffs argue that the financial records provided by Plaintiff
    Shuford were conclusive to show the State’s mathematical calculations used to
    withhold Plaintiffs’ disability statements were incorrect. Since Plaintiffs allege the
    decisions were not supported by substantial evidence, the trial court was required to
    apply a whole record standard of review.           See § 150B-51(c).   The trial court
    appropriately applied such standard, stating “[w]ith respect to assertions of fact-
    based errors, the Court has applied a whole record standard of review.” Thus, we
    conclude the trial court did not err in its standard of review.
    ¶ 28         Next, we examine whether the trial court applied the whole record standard of
    review correctly. The whole record test “requires the examination of all competent
    evidence to determine if the administrative agency’s decision is supported by
    substantial evidence.”     Rector v. North Carolina Sheriffs’ Educ. & Training

    .
    ¶ 29            Applying the whole record standard of review, we consider the following
    evidence. Plaintiff Shuford offered her bank account statements and a spreadsheet
    into evidence. Plaintiff Shuford’s spreadsheet showed the amount of social security
    payments deposited into her bank account, amount of disability payments deposited
    into her bank account, benefits paid by the state, social security offset amount
    calculated by the state, benefit amount the state should have paid, and social security
    offset amount the state should have paid from January 2006 until July 2017.
    Defendant also provided a spreadsheet detailing the amount it actually paid Plaintiff
    Shuford versus the amount it should have paid. The social security offset amount on
    Plaintiff Shuford’s spreadsheet differed from the social security offset amount on the
    spreadsheet prepared by Defendant. For instance, Plaintiff Shuford’s spreadsheet
    MOSS V. N.C. DEP’T OF STATE TREASURER
    2022-NCCOA-206
    Opinion of the Court
    showed the social security offset amount for December 2006 was $1,056.00, while
    Defendant’s spreadsheet showed Plaintiff Shuford’s social security offset amount for
    the same date was $1,090.00.
    ¶ 30         These discrepancies are not due to a calculation error by Defendant, but rather
    are indicative of potential withholdings. Thomas Causey, a witness on behalf of
    Defendant, testified the social security offset amount illustrated on Plaintiff
    Shuford’s spreadsheet statements does not consider potential money withheld by the
    Social Security Administration. Causey further testified that “Social Security has
    other deductions that they take out before . . . direct deposits are made for members.
    . . . So . . . the direct deposits, again, would not help us to know the amount that
    should be deducted.” In other words, the amount of social security offset in Plaintiff
    Shuford’s spreadsheet shows only the net amount of her social security benefits if
    money was withheld, not the gross amount of the benefits. The social security offset
    amount in Defendant’s spreadsheet showed the gross amount of social security
    benefits received by Plaintiff Shuford prior to any withholdings. As a result, if the
    Social Security Administration was withholding money from the gross amount
    provided to an individual, this would be reflected in a lower amount being deposited
    into the individual’s bank account. Nowhere within the record did Plaintiff Shuford
    offer evidence of the gross amount she received from the Social Security
    Administration, only proffering evidence as to the net amount.        Therefore, the
    MOSS V. N.C. DEP’T OF STATE TREASURER
    2022-NCCOA-206
    Opinion of the Court
    administrative law judge had substantial evidence from Defendant’s spreadsheet to
    support its decisions.
    ¶ 31         Assuming arguendo Plaintiff Shuford’s spreadsheet sufficed as contrary
    evidence for the purpose of calculating the overpayment amount, we are not
    permitted to substitute our judgment for that of the administrative law judge just
    because contrary evidence existed. See id.; see also City of Rockingham v. N.C. Dep’t
    of Env’t & Natural Res., 
    224 N.C. App. 228
    , 239, 
    736 S.E.2d 764
    , 771 (2012) (“In an
    administrative proceeding, it is the prerogative and duty of that administrative body,
    once all the evidence has been presented and considered, to determine the weight and
    sufficiency of the evidence and the credibility of the witnesses, to draw inferences
    from the facts, and to appraise conflicting and circumstantial evidence.” (internal
    quotation marks omitted)). In light of the foregoing findings, we hold substantial
    evidence existed regarding the financial records to support the administrative law
    judge’s decisions.
    2. Cost of Living Adjustments
    ¶ 32         Plaintiffs also contend the administrative law judge erred by not considering
    Defendant’s possible overpayments in the years when the Social Security
    Administration did not increase benefits due to a cost of living adjustments (“COLA”).
    Because Plaintiffs challenge whether findings of fact within the decisions were
    supported by substantial evidence, the trial court was required to apply a whole
    MOSS V. N.C. DEP’T OF STATE TREASURER
    2022-NCCOA-206
    Opinion of the Court
    record standard of review. See § 150B-51(c). The trial court appropriately applied
    such standard, stating “[w]ith respect to assertions of fact-based errors, the Court has
    applied a whole record standard of review.” Therefore, we must analyze whether the
    trial court appropriately applied the whole record standard of review.
    ¶ 33          In this case, the administrative law judge made the following relevant findings
    of fact:
    35. Because ORBIT had not been programmed to deduct
    the cost-of-living adjustments from the Transitional
    Benefit accounts, Petitioner Moss’[s] Transitional
    Disability Benefits had not been reduced by the Social
    Security cost-of-living adjustment increases which
    occurred in the years of 2006, 2007, 2008, 2011, 2012, 2013,
    2014, and 2016.
    ...
    56. Subsequently, on June 16, 2017, Respondent notified
    Petitioner Shuford that Social Security cost-of-living
    adjustments had been given in 2006, 2007, 2008, 2011,
    2012, 2013, 2014, and 2016, but that these cost-of-living
    adjustments had not been deducted from Shuford’s
    Transitional Disability Benefits.
    In 2009, 2010, and 2015, no COLA was awarded, and thus, the Social Security
    Administration did not increase its benefits. A careful review of Defendant’s “should
    have paid” spreadsheets for each Plaintiff reveals Defendant did not increase the
    amounts of their social security benefits in the years when no COLA was granted. In
    the administrative law judge’s findings, she omitted the years 2009, 2010, and 2015,
    the same years COLA was not awarded. Accordingly, we hold the administrative law
    MOSS V. N.C. DEP’T OF STATE TREASURER
    2022-NCCOA-206
    Opinion of the Court
    judge considered Defendant’s possible overpayments to Plaintiffs in the years COLA
    was not awarded and substantial evidence supported her findings.
    3. Breach of Contract
    ¶ 34         Finally, Plaintiffs contend the trial court erred by denying their petition for
    judicial review because the administrative law judge did not consider their
    contractual rights to receive disability benefits. We disagree.
    ¶ 35         As explained above, Plaintiffs’ rights to disability payments were subject to
    Chapter 135’s statutory requirements. These requirements, in turn, contained a
    mandatory recoupment clause pursuant to 
    N.C. Gen. Stat. § 135-9
    (b). Thus, by
    accepting disability benefits, Plaintiffs agreed Defendant would recoup any
    overpayments of benefits to them.          Furthermore, a careful review of the
    administrative law judge’s decisions shows she properly considered the mandatory
    recoupment clause inherent to Plaintiffs’ disability benefits. Therefore, substantial
    evidence existed to support the administrative law judge’s conclusions Defendant
    acted within its statutory duty to recoup overpayments made to Plaintiffs, and
    Plaintiffs’ argument is without merit.
    C. Collateral Estoppel
    ¶ 36         Although Defendant crafted a lengthy argument as to why Plaintiffs are barred
    from pursuing their claims in superior court under the doctrine of collateral estoppel,
    collateral estoppel is an affirmative defense under Rule 8 and thus must have been
    MOSS V. N.C. DEP’T OF STATE TREASURER
    2022-NCCOA-206
    Opinion of the Court
    raised in the trial court in order to preserve this argument for appeal. N.C. Gen. Stat.
    § 1A-1, Rule 8(c) (2021); N.C. R. App. P. 10(a)(1). “Failure to plead an affirmative
    defense ordinarily results in waiver of the defense.” Ward v. Beaton, 
    141 N.C. App. 44
    , 49, 
    539 S.E.2d 30
    , 34 (2000).         Defendant raised the affirmative defense of
    collateral estoppel for the first time on appeal, and thus failed to preserve this issue
    for appeal. See also In re D.R.S., 
    181 N.C. App. 136
    , 140, 
    638 S.E.2d 626
    , 628 (2007)
    (since “respondent raise[d] the defenses of collateral estoppel and res judicata for the
    first time on appeal, . . . [respondent] thus failed to properly preserve the issue[]”).
    III.     Conclusion
    ¶ 37         For the foregoing reasons, the trial court did not err by granting Defendant’s
    motion to dismiss. Additionally, the trial court did not err by affirming the OAH
    Decisions entered by the administrative law judge. Accordingly, the orders of the
    trial court are affirmed.
    AFFIRMED.
    Judges ZACHARY and CARPENTER concur.
