On April 10, 2015, the U.S. Court of Appeals for the Eighth Circuit, in a very important ruling, held that the U.S. Army Corps of Engineers' Jurisdictional Determination ("JD") that the property under review was a wetland that constitutes "waters of the United States" and thereby subject to the permitting and enforcement authority of the Corps, can be reviewed by the federal courts on an immediate basis. The case is Hawkes Co., Inc. v. US Army Corps of Engineers. The Court of Appeal's approach was influenced by the Supreme Court's approach in Sackett v. EPA, 132 S. Ct. 1367 (2012)., and the Eighth Circuit held that this JD was indeed a final agency action subject to judicial review, particularly when the choices confronting a property owner who wishes to develop his property are so unappealing.
The Court of Appealst reviewed a long list of federal administrative actions whose serious consequences triggered judicial review, and took issue with the Fifth Circuit's recent in Belle Co., L.L.C., v. US Army Corps of Engineers, 761 F. 3d 383 (2014). There's now a conflict in the circuits, and an appeal to the Supreme Court may be in the offing.
