Number: RS20779 Title: THE SUPREME COURT RULES AGAINST CORPS OF ENGINEERS JURISDICTION OVER "ISOLATED WETLANDS": THE SWANCC DECISION Authors: Robert Meltz, American Law Division Abstract: On January 9, 2001, the Supreme Court handed down the latest in its series of recent decisions relating to the balance between federal and state power in our dual system of government. In Solid Waste Agency of Northern Cook County (SWANCC) v. U.S. Army Corps of Engineers, the Court ruled that the long controversial "migratory bird rule," used by the Corps of Engineers to interpret its authority over "isolated wetlands," exceeded the agency's authority under the Clean Water Act.
