Florida v. Georgia
The Supreme Court sent a long-running water dispute between Florida and Georgia back to the Special Master overseeing it, ruling that he had used too strict a legal standard when he recommended dismissing Florida's case.
The Court said Florida deserved another chance to show that limiting Georgia's water use could meaningfully help the shrinking flow into Florida's Apalachicola River and Bay, without deciding whether Florida will ultimately win.
How it got here: Florida sued Georgia directly in the Supreme Court's original jurisdiction; a Special Master took evidence and recommended dismissing Florida's case, and Florida filed exceptions to that recommendation.
The Case in Depth
What happened
Florida and Georgia share water from three rivers that form the Apalachicola-Chattahoochee-Flint River Basin. Florida, downstream, says Georgia's heavy agricultural use of the Flint River has starved Florida's Apalachicola River and Bay of water, harming its oyster industry and ecosystem. Georgia says its water use is reasonable. The states failed for decades to negotiate a sharing agreement.
The question before the Court
Could Florida still win a cap on Georgia's water use, or had it already failed to show that such a cap would actually help Florida?
The Court's answer
Partly — the Court did not decide whether Florida ultimately wins, but it ruled that the Special Master used the wrong legal yardstick in recommending dismissal. The Master required Florida to prove, with very strong ("clear and convincing") evidence, the specific details of a workable water-sharing decree before he had even determined how much water Florida actually needs or how much harm it has suffered. The Court called that "the cart before the horse."
Instead, at this early stage, Florida only needed to show it was likely that some workable decree could eventually be crafted — a more flexible standard. Applying that lower bar, the Court found Florida had made a sufficient showing, partly because the federal agency that controls the river's dams indicated it would work with any court order. The case goes back to the Special Master for more fact-finding before a final decision on relief.

Why it matters
Farmers, cities, and businesses in both states have a stake in how much water Georgia can draw from the Flint River, and Florida's oyster industry and river ecosystem depend on the outcome. The ruling keeps the dispute alive rather than ending it, meaning more litigation, evidence-gathering, and uncertainty for both states and the federal agency that manages the river system.
What changes now
The case returns to the Special Master, who must make detailed factual findings on issues the Court only assumed or found plausible — including exactly how much water Georgia takes, how much streamflow a cap would add, and how much that would help Florida's rivers, bay, and wildlife. The Special Master will then have to weigh the benefits to Florida against the costs to Georgia before recommending whether Florida is entitled to a decree. This is not a final resolution of the dispute.
What this does not decide
The Court did not decide whether Florida is actually entitled to a water-use cap on Georgia, or whether the benefits to Florida would outweigh the costs to Georgia. It decided only that the Special Master used too strict a standard for a preliminary redressability question, sending the case back for more fact-finding.
Concurrences and dissents
Dissent — Justice Thomas
Justice Thomas argued the Special Master actually applied the correct, well-established 'balance-of-harms' test, not the overly strict standard the majority attacked, and that his factual findings were well-supported. He would have upheld the Special Master's recommendation and denied Florida relief outright, arguing that sending the case back for more findings is pointless because Florida already had a full trial and cannot show it would meaningfully benefit from a cap on Georgia's water use.
How the Court got there
The legal reasoning, step by step
- Because no interstate compact resolves this dispute, the Court applied the doctrine of equitable apportionment — federal common law that lets the Court divide water between states fairly by weighing all relevant circumstances rather than following a fixed formula.
- Under that doctrine, a state suing another state over shared water bears a heavier burden than an ordinary private lawsuit, given the equal sovereign status of both states; it must show by clear and convincing evidence that it has suffered a serious, real injury.
- The Court distinguished that injury-and-harm showing from a separate question — whether it is even possible to craft a workable court order (a remedy) — and found the Special Master had mistakenly demanded clear-and-convincing proof of a workable remedy's fine details before he had made any findings about the scope of the harm or how much water would fix it.
- The Court held that, until such foundational findings exist, a state only needs to show it is likely a workable order can eventually be fashioned, applying principles of flexibility and reasonable approximation rather than rigid precision.
- Applying that relaxed standard to the evidence already in the record — including the federal agency's assurance that it would cooperate with any court order — the Court concluded Florida had cleared this preliminary bar, without yet deciding whether Florida can ultimately prove entitlement to relief under the full harm-versus-benefit balancing test.
