    may be cited as Pivonka v. Corcoran, Slip Opinion No. 2020-Ohio-3476.]
    Class action—Subject-matter jurisdiction—Medicaid—R.C. 5160.37 established
    sole remedy for named plaintiffs and unnamed class members who
    reimbursed Ohio Department of Medicaid on or after September 29, 2007,
    pursuant to department’s right of recovery under former R.C. 5101.58—
    Common pleas court lacked subject-matter jurisdiction over class action
    for named and prospective class plaintiffs whose claims for recovery fall
    within R.C. 5160.37’s express language—Court of appeals’ judgment
    reversed and cause remanded to common pleas court.
    (No. 2019-0084—Submitted January 28, 2020—Decided June 30, 2020.)
    APPEAL from the Court of Appeals for Cuyahoga County, No. 106749,
    1. Under S.Ct.Prac.R. 4.06(B), Maureen Corcoran, the current director of the Ohio Department of
    Medicaid, is automatically substituted for Barbara Sears, the former director, as a party to this action.
    SUPREME COURT OF OHIO
    2018-Ohio-4866.
    _________________
    FRENCH, J.
    {¶ 1} In this appeal, we are asked to determine whether the common pleas
    court had subject-matter jurisdiction over a class action filed by plaintiffs-
    appellees, Michael A. Pivonka and Lisa Rijos. That class action seeks a declaratory
    judgment that former R.C. 5101.58, which relates to Medicaid reimbursements, is
    unconstitutional and also seeks to recover all sums paid to the Ohio Department of
    Medicaid (the “Department”) under that statute.
    {¶ 2} Because R.C. 5160.37 now provides the sole remedy for Medicaid
    program participants to recover excessive reimbursement payments made to the
    Department on or after September 29, 2007, we conclude that the common pleas
    court lacked subject-matter jurisdiction over the class action for the named and
    prospective class plaintiffs whose claims for recovery fall within the statute’s
    express language. We therefore reverse the judgment of the Eighth District Court
    of Appeals affirming the trial court’s decision to certify the class. We remand this
    cause to the trial court to determine whether unnamed prospective class plaintiffs
    who reimbursed the Department before September 29, 2007, can maintain an action
    in the common pleas court.
    I. THE MEDICAID PROGRAM
    {¶ 3} The federal government established the Medicaid program in 1965
    through Title XIX of the Social Security Act, as amended in 42 U.S.C. 1396 et seq.
    Arkansas Dept. of Health & Human Servs. v. Ahlborn, 
    547 U.S. 268
    , 275, 
    126 S. Ct. 1752
    , 
    164 L. Ed. 2d 459
    (2006). The program provides joint federal and state
    funding for medical care for individuals who cannot afford to pay their own medical
    costs.
    Id. States are
    not required to participate in the Medicaid program, but they
    all   do.    Id.;    see    also    Medicaid.gov,   Program   History:   Medicaid,
    https://www.medicaid.gov/about-us/program-history/index.html (accessed June
    2
    January Term, 2020
    18, 2020) [https://perma.cc/D8C7-YRTE].        Through the program, the federal
    government pays the majority of the costs a state incurs providing medical care for
    Medicaid participants; the state pays the rest. Ahlborn at 275. Each state must
    create its own scheme to oversee and administer the Medicaid program. 42 U.S.C.
    1396a. In doing so, a state must comply with all federal statutory requirements for
    making eligibility determinations, collecting and maintaining information, and
    administering the program.
    Id. {¶ 4}
    Federal law also requires that each participating state give itself
    subrogation rights to recover certain costs the state paid under the Medicaid
    program. This means that each state must enact legislation giving it the right to
    seek reimbursement from a third-party tortfeasor (that is, a third-party wrongdoer)
    for medical expenses the third-party wrongdoer caused and that the state paid on
    behalf of a Medicaid participant. 42 U.S.C. 1396a(a)(25)(H). The state must first
    take reasonable measures to determine whether a third party is liable to pay for a
    Medicaid participant’s medical costs. 42 U.S.C. 1396a(a)(25)(A). This third-party
    liability can arise when a health insurer is responsible for paying the participant’s
    medical costs.
    Id. But it
    can also arise if a third-party tortfeasor injures the
    Medicaid participant and the injury requires the participant to seek medical care.
    When a third party is liable to pay for the Medicaid participant’s medical costs, the
    state must seek reimbursement for the medical costs that it paid under the Medicaid
    program. 42 U.S.C. 1396a(a)(25)(B). The state may seek reimbursement directly
    from the third party.
    Id. It may
    also seek reimbursement from a Medicaid
    participant who received payment from the third party for the medical costs. 42
    U.S.C. 1396k(a)(1) requires that all participating states expressly condition an
    individual’s eligibility for Medicaid on the individual’s assignment to the state of
    any rights the individual has to recover medical costs from a third party.

    SUPREME COURT OF OHIO
    II. OHIO’S MEDICAID SUBROGATION RIGHTS STATUTES
    {¶ 5} Ohio’s Medicaid subrogation rights statute was originally contained
    in former R.C. 5101.58, repealed in 2013 Am.Sub.H.B. No. 59. That statute gave
    the Ohio Department of Job and Family Services (“ODJFS” or “the Department”)2
    a “right of recovery” against a third party’s liability to a Medicaid participant for
    medical services and care resulting from an injury, disease or disability caused by
    the third party. Under that statute and prior to September 29, 2007, if the Medicaid
    participant brought an action against a third-party tortfeasor, the entire amount the
    participant received under a settlement or court judgment was subject to the state’s
    right of recovery. 2003 Am.Sub.H.B. No. 95, 150 Ohio Laws, Part II, 1592-1594.
    The state could automatically recover up to the full amount of the costs it paid on
    behalf of the participant, even if the settlement, compromise, judgment or award
    excluded reimbursement for the medical costs or allocated a lesser amount to those
    costs. See
    id. {¶ 6}
    Other states, including Arkansas, had similar Medicaid subrogation
    statutes allowing those states to recover up to the entire amount of the medical costs
    they paid on the Medicaid participant’s behalf without regard to whether the
    settlement or court judgment allocated a lesser amount for reimbursement of
    medical expenses. In 
    Ahlborn, 547 U.S. at 292
    , 
    126 S. Ct. 1752
    , 
    164 L. Ed. 2d 459
    ,
    the United States Supreme Court held that the federal Medicaid statute’s anti-lien
    provision, 42 U.S.C. 1396p, prohibited Arkansas from enforcing its Medicaid
    subrogation statute because it allowed the state to assert an automatic lien on a
    2. The ODJFS was the agency responsible for administering Ohio’s Medicaid program until
    September 29, 2013, when the state created the Ohio Department of Medicaid to administer the
    program. See R.C. 5162.03. As used in this decision, the term “the Department” refers to either the
    Ohio Department of Medicaid or the ODJFS.
    4
    January Term, 2020
    beneficiary’s settlement or judgment proceeds in excess of the portion of the
    settlement or judgment that expressly represented reimbursement for medical costs.
    {¶ 7} Although no court declared Ohio’s statute, R.C. 5101.58, invalid or
    unconstitutional after Ahlborn, the General Assembly amended the statute in 2007.
    2007 Am.Sub.H.B. No. 119. Effective September 29, 2007, the amended statute
    continued to give the Department an automatic right of recovery over certain third-
    party payments to Medicaid participants, but it created a presumption regarding the
    amount of the settlement or judgment that was subject to reimbursement to the
    Department for its payment of medical costs if the settlement or judgment did not
    specifically allocate those sums. After deducting attorney fees, litigation costs, and
    other expenses from the total judgment, award or settlement, the statute provided
    that the Department was entitled to receive “no less than one-half of the remaining
    amount, or the actual amount of medical assistance paid, whichever is less.”
    Former R.C. 5101.58(G)(2).
    {¶ 8} In Wos v. E.M.A. ex rel. Johnson, 
    568 U.S. 627
    , 
    133 S. Ct. 1391
    , 
    185 L. Ed. 2d 471
    (2013), the United States Supreme Court struck down the portions of
    North Carolina’s Medicaid subrogation statute that created a presumption similar
    to the one former R.C. 5101.58(G)(2) contained. The court held that a state could
    not comply with 42 U.S.C. 1396p by using a “conclusive presumption” that one-
    third of the participant’s recovery represented compensation for medical costs.
    Id. at 635-636.
    The presumption operated to allow the state to take a portion of the
    judgment or settlement that was not designated as reimbursement for medical costs.
    The North Carolina statute violated the Supremacy Clause because it failed to
    provide a process for determining the portion of a participant’s recovery that was
    attributable to medical costs.
    Id. at 636.
    Because the federal statute’s anti-lien
    provision prohibits a state from claiming any part of a Medicaid participant’s
    judgment or settlement not designated as payment for medical costs, it preempted
    North Carolina’s Medicaid subrogation statute.
    Id. 5 SUPREME
    COURT OF OHIO
    {¶ 9} After the decision in Wos, and again without a court’s declaration that
    former R.C. 5101.58 was invalid or unconstitutional, the General Assembly
    amended Ohio’s Medicaid subrogation statute and renumbered it as R.C. 5160.37.
    The new statute took effect on September 29, 2013, see 2013 Am.Sub.H.B. No. 59,
    and the General Assembly amended it yet again on September 29, 2015, see 2015
    Sub.H.B. No. 64. The 2015 version of R.C. 5160.37 still contained language
    similar to that in former R.C. 5101.58(A) and (G)(2), giving the Department an
    automatic right of recovery against liability for medical costs paid by a third-party
    tortfeasor.   But, the 2015 version of R.C. 5160.37 created a “rebuttable
    presumption” that the Department would receive no less than one-half of the
    remaining amount of the judgment, award or settlement after fees, expenses, and
    costs were deducted. R.C. 5160.37(G)(2). The statute also provided a mechanism
    for a Medicaid participant to rebut the statute’s presumption by way of an
    administrative hearing. See R.C. 5160.37(L). Relevant to the class of plaintiffs
    involved in this case, the statute created a process to address overpayments made
    after the September 29, 2007 post-Ahlborn amendments to R.C. 5101.58:
    A medical assistance recipient who has repaid money, on or after
    September 29, 2007, to the department or a county department pursuant to
    the department’s or county department’s right of recovery under this
    section, section 5160.38 of the Revised Code, or former section 5101.58 or
    5101.59 of the Revised Code may request a hearing to rebut the presumption
    in division (G) of this section. The request shall be made in accordance
    with the procedure the department establishes for this purpose in rules
    required by division (O) of this section. It must be made not later than one
    hundred eighty days after September 29, 2015, or ninety days after the
    payment is made, whichever is later. A party successfully rebuts the
    6
    January Term, 2020
    presumption by a showing of clear and convincing evidence that a different
    allocation is warranted.
    R.C. 5160.37(L)(2).     If a Medicaid participant disagrees with the hearing
    examiner’s decision under that provision, the participant may file an administrative
    appeal with the Medicaid director. R.C. 5160.37(M). Following an administrative
    appeal, either party may appeal the Medicaid director’s decision to the common
    pleas court in accordance with R.C. 119.12. R.C. 5160.37 does not provide a
    process for challenging alleged overpayments made to the Department before the
    September 29, 2007 amendments to R.C. 5101.58.
    {¶ 10} The statute expressly provides that the administrative procedure
    outlined in divisions (L) through (N) is “the sole remedy available to a party who
    claims the department or a county department has received or is to receive more
    money than [it is] entitled to receive under this section, section 5160.38 of the
    Revised Code, or former section 5101.58 or 5101.59 of the Revised Code.” R.C.
    5160.37(P). According to the Department, it sent notices to participants who had
    reimbursed the Department under the older versions of the Medicaid subrogation
    statute regarding the new administrative-hearing process under R.C. 5160.37.
    III. FACTS AND PROCEDURAL HISTORY
    {¶ 11} Pivonka and Rijos filed their class-action complaint in the Cuyahoga
    County Common Pleas Court on April 5, 2013, before R.C. 5160.37 was enacted.
    Their complaint seeks disgorgement and repayment of all sums the Department
    received pursuant to its right of recovery under former R.C. 5101.58 and a
    declaration that former R.C. 5101.58 is preempted by federal law and is
    unconstitutional under the Supremacy Clause. They argued that former R.C.
    5101.58 is invalid pursuant to the decision in Wos.
    {¶ 12} The named plaintiffs filed their complaint on behalf of themselves
    and similarly situated individuals who had both “received a demand from [the
    7
    SUPREME COURT OF OHIO
    Department] for repayment of medical expenses pursuant to” former R.C. 5101.58
    and had “paid any amount to [the Department] pursuant to the Subrogation Statute.”
    As to the named plaintiffs, Pivonka reached a settlement with a third-party
    tortfeasor in July 2012. Because he had received Medicaid benefits relating to his
    injuries, the Department collected $7,108.74 from the settlement. In 2013, Rijos
    received a compensatory-damages award in a negligence action against a third-
    party tortfeasor following a jury verdict. The Department collected $703.16 of
    Rijos’s award pursuant to its statutory right to subrogation.
    {¶ 13} On April 10, 2013, Pivonka and Rijos moved to certify as a class
    “[a]ll persons who paid any amount to [the Department] pursuant to [former R.C.
    5101.58], from April 6, 2007, to the present, without requirement of court order.”
    {¶ 14} The Department filed a motion to dismiss the complaint and later
    filed a motion for summary judgment, arguing that former R.C. 5101.58 is
    constitutional and that the Department had the right to collect the reimbursements
    under the statute. The trial court denied both motions. The Department also moved
    for judgment on the pleadings, arguing that the General Assembly divested the
    common pleas court of jurisdiction when it enacted R.C. 5160.37. Pivonka and
    Rijos argued in opposition that the General Assembly violated the Ohio
    Constitution’s single-subject rule for legislation when it included the Medicaid
    subrogation statute in a budget bill and further that the legislature cannot strip a
    court of jurisdiction it already has in a pending case. Pivonka and Rijos also argued
    that R.C. 5160.37 does not apply to their action because it applies only to claims
    alleging that the Department received “more money than [it is] entitled [to],” R.C.
    5160.37(P), whereas they asserted that the Department was not entitled to receive
    any money because former R.C. 5101.58 is unconstitutional. The trial court denied
    the Department’s motion for judgment on the pleadings on January 4, 2016, finding
    that the issue should not be decided on the pleadings alone.
    8
    January Term, 2020
    {¶ 15} The trial court certified the class on December 21, 2017. In its
    memorandum opposing class certification, the Department again argued that R.C.
    5160.37 divested the court of jurisdiction. As it had done before, the trial court
    rejected the Department’s argument, determining that plaintiffs’ claims were not
    for mere overpayment to the Department. The trial court also found the argument
    irrelevant to its decision whether to certify the class because a court’s lack of
    subject-matter jurisdiction is an affirmative defense that can be raised later in a
    class action.
    {¶ 16} The Department urged the trial court to adjudicate plaintiffs’
    constitutional arguments before deciding whether to certify the class because that
    determination affected whether the proposed class satisfied the class-certification
    requirements under Civ.R. 23. The trial court declined to do so, finding that a
    determination on the merits of plaintiffs’ constitutional claims would best be made
    after class certification when the claims could be decided as to all members of the
    class instead of through individual lawsuits.
    {¶ 17} The Department appealed the trial court’s December 21, 2017
    decision granting plaintiffs’ motion for class certification to the Eighth District
    Court of Appeals. The court of appeals affirmed the trial court’s decision. It
    determined that R.C. 5160.37 did not divest the trial court of subject-matter
    jurisdiction because Pivonka and Rijos sought a declaratory judgment that former
    R.C. 5101.58 is unconstitutional. 2018-Ohio-4866, 
    125 N.E.3d 343
    , ¶ 39-42. The
    court determined that because administrative agencies cannot decide the
    constitutional validity of a statute and because that was the sole issue underlying
    plaintiffs’ claims, it would be futile and impractical to require plaintiffs to first seek
    redress through the administrative process.
    Id. {¶ 18}
    We accepted jurisdiction to consider the Department’s two
    propositions of law. See 
    155 Ohio St. 3d 1412
    , 2019-Ohio-1205, 
    120 N.E.3d 30
    .
    In its first proposition of law, the Department contends that “[b]y statute, claims
    9
    SUPREME COURT OF OHIO
    that the State overcollected for Medicaid recovery may not be brought in common
    pleas courts, except as an administrative appeal.” In its second proposition of law,
    the Department argues that “[a] class action may be certified only if rigorous
    analysis reveals that all prerequisites have been met—even if that analysis also
    touches upon the merits of the dispute.”
    {¶ 19} The Department also argues in its merit brief for the first time in
    this case that absent the applicability of the administrative-review process
    contained in R.C. 5160.37 to plaintiffs’ claims, the Ohio Court of Claims has
    jurisdiction because plaintiffs’ claims involve a lawsuit for money damages
    against the state.
    IV. ANALYSIS
    {¶ 20} Subject-matter jurisdiction refers to the constitutional or statutory
    power of a court to adjudicate a case. State v. Harper, ___ Ohio St.3d ___, 2020-
    Ohio-2913, ___ N.E.3d ___, ¶ 23. Without subject-matter jurisdiction, a trial court
    has no power to act. State ex rel. Jones v. Suster, 
    84 Ohio St. 3d 70
    , 78, 
    701 N.E.2d 1002
    (1998).     A trial court cannot certify a class if it lacks subject-matter
    jurisdiction over the action.
    {¶ 21} The Ohio Constitution gives the General Assembly the power to
    define the limits of the common pleas courts’ jurisdiction. State v. Wilson, 73 Ohio
    St.3d 40, 42, 
    652 N.E.2d 196
    (1995), citing Article IV, Section 4(B), Ohio
    Constitution. The General Assembly has given the common pleas courts subject-
    matter jurisdiction over all civil cases that it has not expressly excluded from their
    jurisdiction. See Bank of Am., N.A. v. Kuchta, 
    141 Ohio St. 3d 75
    , 2014-Ohio-4275,
    
    21 N.E.2d 1040
    , ¶ 20, citing R.C. 2305.01.
    {¶ 22} The General Assembly has, from time to time, limited the common
    pleas courts’ jurisdiction and conferred jurisdiction to another court. See, e.g., R.C.
    2743.03 (granting Court of Claims exclusive jurisdiction over certain claims filed
    against the state). It has also given jurisdiction to certain administrative agencies
    10
    January Term, 2020
    over cases that the agencies are particularly well suited to handle. See, e.g., R.C.
    4905.26 (granting the Public Utilities Commission of Ohio exclusive jurisdiction
    over claims alleging discriminatory utility rates). The General Assembly vests
    exclusive jurisdiction in an administrative agency when it enacts a comprehensive
    statutory scheme for review by that agency. State ex. rel. Cleveland Elec. Illum.
    Co. v. Cuyahoga Cty. Court of Common Pleas, 
    88 Ohio St. 3d 447
    , 451, 
    727 N.E.2d 900
    (2000), citing Kazmaier Supermarket, Inc. v. Toledo Edison Co., 
    61 Ohio St. 3d 147
    , 153, 
    573 N.E.2d 655
    (1991).
    A. R.C. 5160.37 provides the sole remedy for the unnamed class members who
    reimbursed the Department for medical costs on or after September 29, 2007
    {¶ 23} By enacting R.C. 5160.37, the General Assembly created an
    administrative-review process for Medicaid participants challenging their
    overpayment of money to the Department subject to the statutory presumption
    contained in former R.C. 5101.58(G). That administrative process is, by its own
    terms, the “sole remedy” available to those individuals. R.C. 5160.37(P). It is
    complete and comprehensive. The statute identifies the steps required to request a
    hearing, the timing requirements for requesting a hearing, and the evidentiary
    standard required to rebut the statutory presumption. R.C. 5160.37(L)(1) and (2).
    It prescribes the hearing examiner’s authority to consider and weigh the evidence,
    the Department’s ability to raise affirmative defenses, and other rules that apply to
    the hearing. R.C. 5160.37(L)(3). It provides a process for appealing the hearing
    examiner’s decision to the Department’s director. R.C. 5160.37(M). And it
    provides a process for appealing the director’s decision to the common pleas court.
    R.C. 5160.37(N). Accordingly, it has given tribunals acting under R.C. 5160.37
    exclusive subject-matter jurisdiction over claims alleging that the Department
    received more money than it was entitled to receive under former R.C. 5101.58,
    beginning September 29, 2007. It applies equally to individuals who believe, as
    the purported class does here, that the Department was not entitled to receive any
    11
    SUPREME COURT OF OHIO
    money because that claim necessarily subsumes any claim that the Department
    received more money than it was entitled to receive.
    {¶ 24} Pivonka and Rijos argue that the class members should not be
    required to utilize the administrative-review process under R.C. 5160.37 because
    their entire action is based on a constitutional challenge to former R.C. 5101.58.
    But even though administrative agencies cannot adjudicate constitutional
    questions, see Mobil Oil Corp. v. Rocky River, 
    38 Ohio St. 2d 23
    , 26, 
    309 N.E.2d 900
    (1974), a party cannot circumvent the administrative-review process by first
    raising a constitutional challenge in the common pleas court. Rather, the proper
    procedure for raising a constitutional challenge is to first exhaust all administrative
    remedies. A party can then raise the constitutional challenge in the court that hears
    the administrative appeal. See id.; State ex. rel. Kingsley v. State Emp. Relations
    Bd., 
    130 Ohio St. 3d 333
    , 2011-Ohio-5519, 
    958 N.E.2d 169
    , ¶ 18.
    {¶ 25} Pivonka and Rijos filed this action before R.C. 5160.37 was enacted,
    but the trial court did not certify the class until after R.C. 5160.37 took effect. As
    we have recognized, “unnamed putative class members are not parties to an action
    prior to class certification.” Gembarski v. PartsSource, Inc., 
    157 Ohio St. 3d 255
    ,
    2019-Ohio-3231, 
    134 N.E.2d 1175
    , ¶ 29; see also Smith v. Bayer Corp., 
    564 U.S. 299

    180 L. Ed. 2d 341
    (2011) (the argument that an unnamed
    class member is a party to the class action before the class is certified is a “novel
    and surely erroneous argument”). Because the General Assembly created an
    administrative-review process before any unnamed prospective class members
    became parties in this action, that process governs the prospective class members’
    claims.     Unnamed prospective class members whose claims fall under R.C.
    5160.37(L)(2) may seek redress only through that administrative process.
    Therefore, we hold that the trial court lacked subject-matter jurisdiction over the
    claims of the unnamed prospective class members who reimbursed the Department
    on or after September 29, 2007.

    B. Pivonka and Rijos’s claims are also subject to the administrative-review
    process under R.C. 5160.37
    {¶ 26} We next consider whether the common pleas court had jurisdiction
    over the claims asserted by the two named plaintiffs, Pivonka and Rijos. Both
    Pivonka and Rijos repaid money to the Department after September 29, 2007,
    pursuant to the Department’s exercise of its subrogation rights under former R.C.
    5101.58(G). They fall within the class of individuals whose claims are covered by
    R.C. 5160.37. Although they filed this action before R.C. 5160.37 took effect, we
    conclude that R.C. 5160.37 provided the sole remedy by which the named plaintiffs
    could seek redress after it was enacted.
    {¶ 27} The Ohio Constitution provides that the General Assembly “shall
    have no power to pass retroactive laws.” Ohio Constitution, Article II, Section 28.
    This anti-retroactivity clause protects vested rights from new legislative
    encroachments and nullifies a new statute that creates burdens, duties, obligations
    or liabilities that did not exist when the statute became effective. Longbottom v.
    Mercy Hosp. Clermont, 
    137 Ohio St. 3d 103
    , 2013-Ohio-4068, 
    998 N.E.2d 419
    ,
    ¶ 21. A statute that both applies retroactively and is substantive violates this clause.
    Id. at ¶
    22. A substantive law is one that creates duties, rights, and obligations.
    State ex. rel. Holdridge v. Indus. Comm., 
    11 Ohio St. 2d 175
    , 178, 
    228 N.E.2d 621
    (1967).
    {¶ 28} In contrast, remedial legislation does not create, remove or affect any
    rights; it merely affects the methods and procedure by which rights are recognized,
    protected, and enforced.       Longbottom at ¶ 25; see also Holdridge at 178 (a
    procedural or remedial law “prescribes methods of enforcement of rights or
    obtaining redress”). The anti-retroactivity clause does not prohibit remedial laws.
    Longbottom at ¶ 25. Rather, the legislature has complete control over the remedies
    afforded to parties. It is a fundamental principle of law that a party may not acquire
    a vested right in a remedy or any part of it. Morgan v. W. Elec. Co., Inc., 
    69 Ohio 13
                                 SUPREME COURT OF OHIO
    St.2d 278, 281, 
    432 N.E.2d 157
    (1982), fn. 5. Litigants have no right to a particular
    remedy or procedure, and nothing prohibits the legislature from altering or
    modifying methods, procedures or remedies as it sees fit. Id.; see also State ex rel.
    Michaels v. Morse, 
    165 Ohio St. 599
    , 605-606, 
    138 N.E.2d 660
    (1956). To that
    end, both this court and the United States Supreme Court have recognized that
    legislatures can enact remedial laws that affect a tribunal’s jurisdiction without
    offending a constitution’s anti-retroactivity clause. See Longbottom at ¶ 25-27
    (Ohio Constitution); Landgraf v. USI Film Prods., 
    511 U.S. 244
    , 275, 
    114 S. Ct. 1483
    , 
    128 L. Ed. 2d 229
    (1994) (United States Constitution).             This includes
    legislation that affects a court’s jurisdiction over a pending case. See, e.g., Morgan
    at 284-285.
    {¶ 29} In Landgraf, the United States Supreme Court recognized that it has
    “regularly applied intervening statutes conferring or ousting jurisdiction, whether
    or not jurisdiction lay when the underlying conduct occurred or when the suit was
    filed,” without violating federal anti-retroactivity principles. Landgraf at 274. As
    the court explained, application of a new jurisdictional rule does not take away any
    substantive right; it simply changes the tribunal authorized to hear the case.
    Id. Jurisdictional statutes
    speak to the power of the court, not the rights or obligations
    of the parties.
    Id., citing Republic
    Natl. Bank of Miami v. United States, 
    506 U.S. 80
    , 100, 
    113 S. Ct. 554
    , 
    121 L. Ed. 2d 474
    (1992) (Thomas, J., concurring).
    {¶ 30} Here, R.C. 5160.37 has established an administrative-review process
    that is expressly “remedial in nature.” R.C. 5160.37(P). Rather than affecting any
    substantive rights, it changes the tribunal available to a Medicaid participant who
    claims the Department received more money than it was entitled to receive under
    the Medicaid subrogation statutes.
    {¶ 31} Because the statute does not affect a substantive right, we apply it as
    written. The administrative-review process contained in R.C. 5160.37(L) through
    (N) provides the sole avenue of redress for any “medical assistance recipient who
    14
    January Term, 2020
    has repaid money, on or after September 29, 2007, to the department or a county
    department pursuant to the department’s or county department’s right of recovery
    under this section, section 5160.38 of the Revised Code, or former section 5101.58
    or 5101.59 of the Revised Code,” R.C. 5160.37(L)(2), and “who claims the
    department or a county department has received or is to receive more money than
    [it is] entitled to receive,” R.C. 5160.37(P). This includes named plaintiffs Pivonka
    and Rijos.    Pivonka and Rijos were required to raise their claims with the
    Department pursuant to the process set forth in R.C. 5160.37(L) through (N).
    C. The trial court must decide whether it has subject-matter jurisdiction over the
    plaintiffs who are not subject to R.C. 5160.37
    {¶ 32} Our application of R.C. 5160.37 does not address the entire certified
    class. R.C. 5160.37(L)(2), by its terms, applies only to participants who repaid
    money to the Department on or after September 29, 2007. But the class that the
    trial court certified includes participants who repaid money to the Department
    beginning on April 6, 2007.         Those participants who repaid money to the
    Department between April 6 and September 28, 2007, are not required to request a
    hearing with the Department to challenge the Department’s exercise of its
    subrogation rights.
    {¶ 33} The Department argues for the first time on appeal here that in the
    absence of the applicability of the administrative-review process contained in R.C.
    5160.37 to the plaintiffs’ claims, the Court of Claims has exclusive jurisdiction over
    this action because plaintiffs seek legal, rather than equitable, relief. Subject-matter
    jurisdiction involves the power of a court to adjudicate a case. As such, it can never
    be waived, and it may be challenged at any time. Pratts v. Hurley, 
    102 Ohio St. 3d 81
    , 2004-Ohio-1980, 
    806 N.E.2d 992
    , ¶ 11.
    {¶ 34} When subject-matter jurisdiction is challenged, “ ‘the party claiming
    jurisdiction bears the burden of demonstrating that the court has jurisdiction over
    the subject matter.’ ” Marysville Exempted Village School Dist. Bd. of Edn. v.
    15
    SUPREME COURT OF OHIO
    Union Cty. Bd. of Revision, 
    136 Ohio St. 3d 146
    , 2013-Ohio-3077, 
    991 N.E.2d 1134
    , ¶ 10, quoting Ohio Natl. Life Ins. Co. v. United States, 
    922 F.2d 320
    , 324 (6th
    Cir.1990). We have explained that the classification of a claim for restitution as
    either equitable or legal depends on the traceability of the funds the plaintiff seeks
    to recover. Cleveland v. Ohio Bur. of Workers’ Comp., ___ Ohio St.3d ___, 2020-
    Ohio-337, ___ N.E.3d ___, ¶ 11, 16.
    {¶ 35} Here, because the Department did not raise its jurisdictional
    challenge in the trial court, the record has not been fully developed as to the relevant
    jurisdictional facts, including the disposition of the funds for which plaintiffs seek
    restitution. We therefore will not consider whether the Court of Claims has
    exclusive jurisdiction over plaintiffs’ claims.
    {¶ 36} Because R.C. 5160.37(L)(2) does not apply to claims made by
    participants who repaid money to the Department between April 6 and September
    28, 2007, and we will not consider whether the Court of Claims has exclusive
    jurisdiction over those claims without further development of the record, we
    remand this cause to the trial court for further consideration. On remand, the record
    can be fully developed and the trial court can determine whether those unnamed
    plaintiffs who repaid money to the Department between April 6 and September 28,
    2007, can maintain their action.
    V. CONCLUSION
    {¶ 37} We hold that R.C. 5160.37 created the sole remedy for the named
    plaintiffs and the unnamed class members who repaid money to the Department on
    or after September 29, 2007, pursuant to the Department’s right of recovery under
    former R.C. 5101.58. We remand this cause to the trial court to determine whether
    it has jurisdiction over claims made by participants who repaid money to the
    Department between April 6 and September 28, 2007. Based on our disposition of
    the Department’s first proposition of law and our remand to the trial court for it to
    consider the remaining unnamed plaintiffs’ claims, we need not address the
    16
    January Term, 2020
    Department’s second proposition of law. We reverse the judgment of the Eighth
    District Court of Appeals and remand this cause to the trial court for further
    consideration.
    Judgment reversed
    and cause remanded.
