JUSTICE VERDIN: Mark and Jane Thompson (the Thompsons) brought this action against Clay Killian, in his official capacity as Aiken County Administrator; Jason Goings, in his official capacity as Treasurer of Aiken County; Aiken County Council; Aiken County; the City of Aiken; Aiken City Council; and Stuart Bedenbaugh, in his official capacity as Aiken City Manager (collectively "Respondents"), seeking declaratory and monetary relief for the imposition of Aiken City and County's road maintenance fees. After the trial court granted Respondents' Rule 12(b)(1) and (6), SCRCP, motions, the Thompsons appealed to the court of appeals. We certified that appeal and now answer whether the trial court erred in (1) finding the South Carolina Revenue Procedures Act (RPA)1 deprived it of subject matter jurisdiction over the Thompson's tax claims; (2) finding that the catchall provision of section 12-60-80(C) barred the Thompsons' class action; (3) dismissing the Thompsons' claim under section 8-21-30 of the South Carolina Code (2019); (4) finding that sovereign immunity barred the Thompsons' unjust enrichment claim; and (5) dismissing the Thompsons' claim under Article I, § 3 of the South Carolina Constitution. We affirm in part, reverse in part, and remand to the trial court to allow the declaratory judgment cause of action to proceed individually and as a class.

1 S.C. Code Ann. §§ 12-60-10 to -3390 (2014 & Supp. 2024). I. Factual and Procedural Background In 1992, following this Court's decision in Brown v. County of Horry, 308 S.C. 180, 417 S.E.2d 565 (1992), Aiken County Council passed ordinance 95-5-19, establishing a road maintenance fee to be paid for each registered vehicle in Aiken County. That ordinance read: Effective July 1, 1992, a mandatory road maintenance fee as established in the annual County Operating Budget Ordinance on each motorized vehicle licensed in Aiken County is to be included on motor vehicle tax notices with the proceeds going into a separate fund for accounting purposes specifically to be used for maintenance and improvements of the county road system, to include road signs and correction of drain-age problems impacting the county road system. AIKEN COUNTY, S.C., CODE § 95-5-19 (1992). Aiken County continuously enforced that ordinance, and in 2021, the fee was twenty-five dollars per registered vehicle.

In 2017, the City of Aiken amended the Aiken City Code to establish a road maintenance fee like Aiken County's. That ordinance read: Effective January 1, 2017, a mandatory road maintenance fee as established in the annual City Operating Budget Ordinance on each motorized vehicle licensed in the City is to be included on motor vehicle tax notices with the proceeds going into a separate fund for accounting purposes specifically to be used for maintenance and improvements of the city road system, to include road signs and correction of drainage problems impacting the city road system. AIKEN, S.C., CODE § 06202016 (2016). However, after our decision in Burns v. Greenville County Council, 433 S.C. 583, 861 S.E.2d 31 (2021), the City of Aiken adopted Ordinance Number 08232021F, AIKEN, S.C., CODE § 08232021F (2021), rescinding the road maintenance fee effective July 1, 2021, and requiring the City to reimburse all road maintenance fees paid after that date.

The Thompsons reside in Aiken County within the limits of Aiken City and have paid both road maintenance fees in all years they were levied. In November 2021, the Thompsons brought this action, individually and as a class, against Respondents. In their complaint, the Thompsons sought a declaratory judgment that the ordinances were invalid under section 6-1-300(6) of the South Carolina Code (2004 & Supp. 2025), as interpreted in Burns, 433 S.C. at 587–88, 861 S.E.2d at 33, and a refund of any unlawfully obtained taxes; (2) damages through an unjust enrichment claim against all Respondents, entitling them to reimbursement of all fees paid; (3) damages through violation of section 8-21-30 against Killian, Goings, and Bedenbaugh, entitling them to ten times the amount of fees improperly charged; and (4) damages or injunctive relief through violation of the Thompsons' rights under Article I, § 3 of the South Carolina Constitution.2

A month later, Aiken City and County filed separate motions to dismiss under Rules 12(b)(1) and (6), SCRCP. The trial court then set a hearing on those motions for April 2022. Before that hearing, the Thompsons agreed to dismiss the action against Aiken County Council and Clay Killian. They also agreed to dismiss the section 8- 21-30 claim against Bedenbaugh. At the hearing, the Thompsons further stipulated that the declaratory judgment action against the City of Aiken was moot and agreed to dismiss the Article I, § 3 claim because they could not seek monetary relief under the South Carolina Constitution. 3 As a result, the remaining claims were (1) the declaratory judgment claim against Aiken County; (2) the unjust enrichment claim against all Respondents except Aiken County Council and Killian; and (3) the section 8-21-30 claim against Goings.

In companion orders filed in August 2022, the trial court found that it did not have subject matter jurisdiction over the Thompsons' remaining claims because section 12-60-80(C), as interpreted in Aiken v. S.C. Dep't of Revenue, 429 S.C. 414, 839 S.C.2d 96 (2020), barred class actions against political subdivision like cities and counties. The trial court declined to reach the City and County's other jurisdictional and sovereign immunity defenses.

The Thompsons then filed motions for reconsideration for both dismissals. The trial court reaffirmed its prior ruling, but, because those dismissals interpreted the complaint as a class action, the trial court scheduled oral arguments to consider the remaining issues. That hearing was set for February 2023.
