585 U.S. 803
SCOTUS2018Background
- Florida (downstream) sued Georgia (upstream) in the Supreme Court under the Court’s original jurisdiction seeking an equitable apportionment (a cap) of water withdrawals from the Apalachicola‑Chattahoochee‑Flint (ACF) Basin to remedy ecological and economic harms in Florida (notably oyster collapse after 2012).
- The Court appointed a Special Master to take extensive evidence; the United States (Army Corps of Engineers) declined to waive sovereign immunity and was not a party.
- The Special Master assumed for purposes of a threshold remedy question that Florida suffered injury and that Georgia’s consumptive uses were excessive, but recommended dismissal because Florida had not proved by clear and convincing evidence that a cap on Georgia alone would redress Florida’s harms given the Corps’ operational discretion at its reservoirs/dams.
- Florida filed exceptions arguing the Master applied an unduly strict standard for showing redressability and, in any event, had made a sufficient showing that a cap would materially increase flows to the Apalachicola and remedy harm.
- The Supreme Court (majority) held the Special Master applied too strict a standard: Florida need only show it is likely possible to fashion an effective decree (given flexibility and approximation), and on the record Florida made a legally sufficient showing that a Georgia cap could increase flows into the Apalachicola and materially redress harm; the case is remanded for additional findings. Justice Thomas dissented.
Issues
| Issue | Plaintiff's Argument (Florida) | Defendant's Argument (Georgia & Corps) | Held |
|---|---|---|---|
| Whether the Special Master required too strict a redressability standard | Florida: initial redressability showing should not demand detailed, clear‑and‑convincing proof of a fully worked‑out decree before factfinding; need only show it is likely a workable decree can be fashioned | Georgia/Master: Florida must prove by clear and convincing evidence that a cap on Georgia (without binding Corps) will actually increase flows to Florida when needed | Court: Master applied too strict a standard; remanded—complaining State must show it is likely possible to fashion an effective decree, not fully prove every remedial detail upfront |
| Whether Florida made the requisite threshold showing that a Georgia cap (without Corps bound) could materially increase flows into the Apalachicola | Florida: experts estimate 1,500–2,000 cfs reductions in depletions during droughts; Corps protocols and US position make it reasonably likely extra basin inflow would pass through or yield more nondrought days when pass‑through occurs | Georgia/Master: Corps can offset Flint inflows by reducing Chattahoochee releases; during drought operations Corps’ rules cap outflow at 5,000 (or 4,500) cfs so extra Flint inflow would often not reach Florida when needed | Court: On assumed facts, Florida made a legally sufficient showing that a cap could yield material increases to Apalachicola flows; further factual findings required on remand |
| Whether the Corps’ operational discretion makes meaningful relief impossible without joining the United States | Florida: Corps’ revised Master Manual and United States’ statements indicate the Corps would cooperate and in many settings would allow additional inflows to pass through; Corps need not be a party to obtain effective relief | Georgia/Master: Corps’ sovereign immunity and discretion mean a decree limited to Georgia might be futile because Corps would not be bound to change releases | Court: Corps’ discretion does not render relief precluded; record and US representations make it plausible a decree could work; remand for findings; US may assist implementation |
| Whether ultimate equitable apportionment should be granted now | Florida: has shown sufficient initial redressability to proceed to full equitable balancing | Georgia: record does not show benefits outweigh harms; Master found insufficient proof of appreciable benefit | Court: reserved ultimate disposition; remanded for additional factfinding and full balancing (benefits must substantially outweigh harms to obtain decree) |
