BOGGS, Judge.

On May 16, 2011, the Georgia Supreme Court held the 2008 Georgia Charter Schools Commission Act, OCGA § 20-2-2081 et seq., unconstitutional because it violated the "special schools" provision of the Georgia Constitution, Ga. Const. of 1983 Art. VIII, Sec. V, Par. VII(a). Gwinnett County School Dist. v. Cox, 289 Ga. 265, 710 S.E.2d 773 (2011). On March 2, 2012, the Bulloch County School District ("the District"), one of seven plaintiff-appellants in the litigation, id. at 265 n. 1, 710 S.E.2d 773, filed a "Motion for an Order Directing the Georgia Department of Education to Disgorge Funds Wrongfully Withheld from the District," arguing that the Supreme Court's decision should be applied retroactively under the three-pronged test established by the U.S. Supreme Court in Chevron Oil Co. v. Huson, 404 U.S. 97, 92 S.Ct. 349, 30 L.Ed.2d 296 (1971). See Findley v. Findley, 280 Ga. 454, 460, 629 S.E.2d 222 (2006). The Department responded, asserting that the District's claim was barred by sovereign immunity, that the claim was properly for money had and received and was asserted against the wrong party, that the claim was barred by the principles of unclean hands and laches, and that the Supreme Court's decision should not be applied retroactively. The District did not file a reply brief below.

The trial court denied the District's motion in a brief, nonspecific order, and the District appeals, arguing for the first time on appeal that its claim for disgorgement of funds falls under the contractual waiver to sovereign immunity in Ga. Const. Art. I, Sec. II, Par. IX (c) and OCGA § 50-21-1(a). Because the District's claim is barred by sovereign immunity, we affirm.

1. Ga. Const. Art. I, Sec. II, Para. IX (e) provides:

Here, the District's claim amounts to an action for money had and received or unjust enrichment. Such actions are barred by sovereign immunity. DeKalb County School Dist. v. Gold, 318 Ga.App. 633, 640(1)(b), 734 S.E.2d 466 (2012) (bars action for money had and received, unjust enrichment, or promissory estoppel); Georgia Dept. of Community Health v. Data Inquiry, 313 Ga.App. 683, 687(2), 722 S.E.2d 403 (2012) (bars action for unjust enrichment or quantum meruit). "The doctrine of sovereign immunity shields the state from suits seeking to recover damages .... the primary purpose of sovereign immunity is to protect state coffers." (Citations and footnotes omitted.) In the Interest of A.V.B., 267 Ga. 728(1), 482 S.E.2d 275 (1997) (sovereign immunity allows complaint seeking injunctive relief and no damages).1 The District's claim therefore is barred by sovereign immunity.

Moreover, the District failed to preserve the claim of waiver which it now asserts for the first time before this court. "Sovereign immunity is not an affirmative defense (see OCGA § 9-11-8(c)) that must be established by the party seeking its protection. Instead, immunity from suit is a privilege that is subject to waiver by the State, and the waiver must be established by the party seeking to benefit from the waiver." Ga. Dept. of Human Resources v. Poss, 263 Ga. 347, 348(1), 434 S.E.2d 488 (1993), overruled on other grounds, Hedquist v. Merrill Lynch, 272 Ga. 209, 211(1), 528 S.E.2d 508 (2000). The District, not the Department, therefore had the burden of establishing a waiver of sovereign immunity. Id.

The Department asserted its defense of sovereign immunity in its answer and in its response to the District's motion. The District, however, did not assert any waiver of sovereign immunity in its complaint or in its motion seeking funds from the Department. Nor did it file a reply brief responding to the Department's assertion of sovereign immunity with respect to its motion. It never asserted any claim of waiver under OCGA § 51-21-1(a) of the claim of sovereign immunity until it filed its brief in this court.2

The posture of this case therefore is directly controlled by Seay v. Cleveland, 270 Ga. 64, 66(2), 508 S.E.2d 159 (1998). In that case, the Georgia Supreme Court reversed the decision of this court holding that an action on a sheriff's bond under OCGA § 15-6-5 was "an action ex contractu as to which sovereign immunity is waived by OCGA § 50-21-1(a)." Id. at 66(2), 508 S.E.2d 159. The Supreme Court held that the plaintiffs "made no such allegation in their complaint or motion for directed verdict or on appeal to the Court of Appeals. Inasmuch as the issue of whether the county's sovereign immunity had been waived by OCGA § 50-21-1(a) was never presented to nor ruled upon by the trial court, it presents nothing for review on appeal. [Cit.]" See also Kelleher v. State of Georgia, 187 Ga.App. 64, 64-65(1), 369 S.E.2d 341 (1988), in which we noted that because the appellant never alleged a waiver of sovereign immunity below, the State was not required to address it. Moreover, the trial court was never presented with the issue and never ruled on it, and we held, "Consequently, this contention presents nothing for review on appeal. [Cit.]" Id.

2. Based upon our holding in Division 1, we need not address the District's remaining enumeration of error regarding the retroactivity of the Supreme Court's decision in Gwinnett County, supra.

Judgment affirmed.
