Facts of the case
Using electronic beepers and aerial photography, police tracked certain drug making supplies to Ronald Dale Dunn’s ranch. The ranch had a fence surrounding the perimeter as well as several interior fences. Law enforcement officers entered the property without a warrant and crossed several fences to get near Dunn’s barn. The barn was about 60 yards away from Dunn’s house and a fence separated the two buildings. Police smelled phenylacetic acid and heard a motor running in the barn. Police approached the barn but did not enter. The officers did shine a flashlight through netting above the door and observed what looked like a drug laboratory. The officers made several similar visits, not entering, but looking into the barn, before obtaining a warrant to search the barn and Dunn’s house. During this search, police seized chemicals and equipment use for making drugs.
At trial, Dunn unsuccessfully moved to suppress evidence obtained during the search. A jury convicted him on federal drug charges. The U.S. Court of Appeals for the Fifth Circuit reversed, holding that the barn was “within the curtilage” of Dunn’s house, so the police officers’ warrantless visits to the barn violated the Fourth Amendment. The U.S. Supreme Court vacated the court of appeals judgment and remanded in light of Oliver v. United States. This time, the court of appeals found that the warrantless searches of the barn violated Dunn’s reasonable expectation of privacy.
Is a search warrant needed to peer into the open side of a barn that is located in a field on private property?
