Rapanos v. United States, 547 U.S. 715 (2006), was a United States Supreme Court case challenging federal jurisdiction to regulate isolated wetlands under the Clean Water Act. It was the first major environmental case heard by the newly appointed Chief Justice, John Roberts and Associate Justice Samuel Alito. The Supreme Court heard the case on February 21, 2006 and issued a decision on June 19, 2006. Ultimately, Rapanos agreed to a nearly $1,000,000 settlement with the EPA without admitting to any wrongdoing.
