A unanimous U.S. Supreme Court has published its decision in Sackett v. EPA, an Idaho couple’s lawsuit challenging an Environmental Protection Agency administrative order issued to the couple after they partly filled a 0.63-acre lot to build their house without first obtaining a federal permit under the Clean Water Act.

The Supreme Court held that the Sacketts were entitled to challenge the EPA’s administrative order as a final agency action subject to judicial review under the Administrative Procedure Act because the Clean Water Act did not otherwise preclude such review.
