Department of Transportation v. Mixon

Cathy Mixon sued the Georgia Department of Transportation, claiming a road-widening project left her property flooded because the state failed to maintain its storm drainage systems. She asked for money damages and also for a court order (an injunction) to stop the ongoing flooding. GDOT argued sovereign immunity, the general rule that the government cannot be sued without its consent, blocked her request for an injunction even though courts have long allowed such claims for money damages. The Supreme Court of Georgia held that the constitutional Just Compensation Provision waives the state's immunity from injunction claims in two situations: when the state owes compensation before taking property but has not paid it, or when the state has not gone through the legal process of formally condemning the property at all. Because GDOT had not paid Mixon or formally condemned her land, and denied it had taken anything, her claim for an injunction could go forward. The court affirmed the Court of Appeals but on narrower grounds.

The Just Compensation Provision waives sovereign immunity for injunctive relief claims in two circumstances: where prepayment of compensation is constitutionally required but has not occurred, or where the government has not invoked its formal eminent domain power. Because GDOT had done neither here, Mixon's injunction claim was not barred.

The ruling clarifies that Georgia landowners harmed by government flooding, drainage, or similar damage can seek court orders stopping the harm, not just money, when the government has not paid compensation or formally exercised its condemnation power. This affects how state and local agencies handle property disputes and infrastructure projects statewide.

Affirmed

1. The court explained that sovereign immunity, the rule that the state cannot be sued without its consent, can be waived not only by explicit statutory language but also by necessary implication arising from a constitutional provision.
2. Reviewing the history of the Just Compensation Provision (Georgia's constitutional requirement that private property not be taken or damaged for public use without compensation, usually paid first), the court found that Georgia courts have long allowed injunctions to stop government encroachments on private land when compensation was not paid or eminent domain was not properly invoked.
3. The court analyzed its own precedent, including Baranan v. Fulton County, distinguishing cases where no actual taking or physical damage occurred (where injunctions were barred) from cases involving trespass-like encroachments on private land (where injunctions were allowed), and concluded the latter category still holds today.
4. Applying that framework, the court reasoned that because GDOT had not paid Mixon for the alleged flooding damage and had not gone through the formal eminent domain condemnation process, its claim of immunity could not block her request for an injunction.
5. The court noted that later constitutional amendments narrowing the prepayment requirement for certain public purposes might limit this waiver in other cases, but GDOT never argued its actions fell into an exempt category, so that question did not need to be resolved here.
6. The court clarified that finding immunity waived does not mean Mixon will actually win an injunction on the merits, since equitable remedies require showing no adequate remedy at law exists, a separate question left for further proceedings.
