McMillian, Judge. MMT Holdings, LLC filed this putative class action[1] against the City of Dublin School District (“School District”) and City of Dublin, Georgia (“City”) (collectively “Defendants”), seeking a refund from Defendants of ad valorem taxes MMT contends were illegally assessed and used by the School District to meet obligations not approved by the voters, as well as an injunction against the City to bar it from transferring the taxes it had collected over to the School District. MMT filed a motion for partial summary judgment, asserting it was entitled to a refund of the assessed ad valorem tax increase, and the School District filed a motion for summary judgment arguing, among other things, that the doctrine of sovereign immunity bars MMT’s claims. Following a hearing, the trial court entered an order denying the School District’s motion for summary judgment and granting MMT’s motion. The School District appealed to our Supreme Court, and the Supreme Court transferred the appeal to this Court.[2] Because we agree MMT’s claims against the School District are barred by sovereign immunity, we now reverse. 1. We turn first to the threshold issue of sovereign immunity. See City of Tybee Island v. Harrod, 337 Ga. App. 523, 524 (788 SE2d 122) (2016). Our law is well settled that school districts are political subdivisions of this State and are protected by sovereign immunity unless immunity is waived by an act of the Georgia legislature or within the Georgia Constitution. See Ga. Const. of 1983, Art. I, Sec. II, Par. IX (e); Ga. Const. of 1983 Article IX, Section II, Paragraph IX.[3] Hunt v. City of Atlanta, 245 Ga. App. 229, 229-30 (537 SE2d 11) (2000); Davis v. Dublin City Bd. of Ed., 219 Ga. App. 121, 122 (1) (464 SE2d 251) (1995); see generally Gilbert v. Richardson, 264 Ga. 744, 745 (1) (452 SE2d 476) (1994) (In Georgia, sovereign immunity “protect[s] governments at all levels from unconsented-to legal actions.”). Here, MMT, who bears the burden of establishing waiver,[4] asserts that the legislature waived the School District’s immunity by enacting OCGA § 48-5-380 (a) (1), which it contends entitles them to seek a refund against the School District and the City for the allegedly illegally assessed taxes.[5] OCGA § 48-5-380 (a) (1) provides in relevant part(a) As provided in this Code section, each county and municipality shall refund to taxpayers any and all taxes and license fees: (1)Which are determined to have been erroneously or illegally assessed and collected from the taxpayers under the laws of this state or under the resolutions or ordinances of any county or municipality[.] (Emphasis added.) Under subsections (b) and (c) of that code section, the taxpayer may either file a claim for refund with the governing authority of the county or municipality within the prescribed time or proceed directly to filing suit.[6] Thus, while the plain language of the statute entitles taxpayers to seek a refund from the governing body of a county and municipality, the statute says nothing about filing suit or seeking a refund from a school district and does not contain any language that could be read as broadening the waiver of immunity to encompass governmental entities other than those specifically listed. Cf. Tift County School Dist. v. Martinez, 331 Ga. App. 423, 427-28 (1) (771 SE2d 117) (2015) (use of phrase “or any other political subdivision of this State” in the statute waived immunity to governmental entities other than those specifically listed). MMT points to no other statute that would authorize the type of claims it has asserted against the School District, and we have found none. Accordingly, the School District has immunity from the claims asserted against it, and the trial court should have granted the School District’s motion for summary judgment.2. In light of our holding in Division 1, it is unnecessary for us to address the School District’s remaining contentions. However, we make plain that nothing in this opinion is intended to address MMT’s claims against the City as the City did not move for summary judgment and is not party to this appeal.Judgment reversed. Barnes, P. J., and Reese, J., concur.
