U.S. Army Corps of Eng'rs v. Hawkes Co.
The Supreme Court ruled that when the Army Corps of Engineers issues a formal 'jurisdictional determination' saying a property contains federally protected wetlands, landowners can immediately challenge that determination in court rather than waiting years through the permit process or risking prosecution.
The decision gives property owners facing the Clean Water Act's costly and lengthy permitting maze an earlier, more practical way to get a judge to review the government's wetlands finding before they must gamble with major fines or years of paperwork.
How it got here: A federal district court dismissed the companies' lawsuit challenging the wetlands determination for lack of jurisdiction; the Eighth Circuit reversed, and the government sought Supreme Court review.
The Case in Depth
What happened
Three Minnesota companies that mine peat wanted to expand into wetlands on land they owned. Before mining, they applied to the Army Corps of Engineers for a permit to discharge material into the wetlands. The Corps issued an official 'jurisdictional determination' declaring the wetlands were connected enough to a distant river to count as federally protected waters, subjecting the companies to the Clean Water Act's permit requirements.
The question before the Court
Could a landowner go to federal court to challenge the Army Corps of Engineers' official determination that their property contained protected wetlands, before applying for a permit?
Why it matters
Landowners, developers, and businesses who might discharge material near wetlands no longer have to choose between an expensive multi-year permit process and risking huge fines by acting first and fighting in court later. They can go straight to court to challenge the Corps' wetlands finding, which should make it faster and cheaper to resolve disputes over whether federal rules even apply to a piece of land.
What changes now
The ruling is final on the legal question of reviewability; it does not resolve whether the specific wetlands at issue are actually protected under the Clean Water Act. The case's practical effect is nationwide: landowners receiving similar jurisdictional determinations can now go straight to federal court to challenge them, without first completing a permit application or risking an enforcement action.
What this does not decide
The Court did not decide whether the wetlands on the companies' property actually qualify as federally protected waters under the Clean Water Act — only that landowners may seek court review of the Corps' determination on that question. It also did not resolve broader disputes over how far the Clean Water Act's jurisdiction extends.
Concurrences and dissents
Concurrence — Justice Kennedy
Justice Kennedy joined the Court's opinion in full but wrote separately to flag that the Clean Water Act's reach remains troublingly unclear and its penalties can be crushing even for accidental violations. He noted the government had argued the interagency memorandum the majority relied on was not truly binding, and warned that without a reliable jurisdictional-determination process, the Act raises serious concerns about government power over private property.
Concurrence — Justice Kagan
Justice Kagan joined the majority in full but wrote separately to stress that, unlike Justice Ginsburg, she saw the interagency memorandum binding the Corps and EPA as central to the case. She explained that the memorandum's five-year safe harbor for negative determinations is itself the direct legal consequence needed to make the determination final and reviewable.
Concurrence in part — Justice Ginsburg
Justice Ginsburg agreed the determination was final and reviewable but declined to join the majority's reliance on the interagency memorandum between the Corps and EPA, noting the parties barely briefed it and the government disputed the Court's reading. She reasoned the determination was final simply because it was definitive and had an immediate practical impact, without needing the memorandum.
How the Court got there
The legal reasoning, step by step
- The Court applied its two-part test from Bennett v. Spear for deciding when an agency's action is 'final' and therefore reviewable in court: the action must represent the agency's last word, and it must produce real legal consequences.
- The Court found the wetlands determination was the agency's last word because it followed extensive factfinding, was formally labeled 'final agency action' by the Corps' own regulations, and normally stays in effect for five years without being revisited.
- The Court found real legal consequences flowed from the determination because a finding that wetlands are NOT protected creates a five-year shield from government lawsuits and narrows who can sue, so a finding that wetlands ARE protected takes that shield away, which itself is a concrete legal effect.
- The Court then asked whether landowners had to use some other route instead of immediate court review, and concluded that neither waiting to be sued (which risks severe fines) nor completing the costly, multi-year permit process first was an adequate substitute.
- Because the Clean Water Act says nothing about these standalone wetlands determinations, the Court found no reason to read the law as blocking court review of them, especially given the general presumption that final agency actions can be reviewed in court.
