United States v. Dunn
Citation and Court
480 U.S. 294 (1987) — Supreme Court of the United States
Facts
DEA agents crossed several fences on Dunn’s rural property and approached a barn located approximately 50 yards from the house. They looked through the barn’s mesh wire and observed a drug laboratory. The agents had not obtained a warrant. Dunn argued the barn was within the curtilage of his home.
Issue
Whether a barn located some distance from the farmhouse falls within the curtilage of the home and is thus entitled to Fourth Amendment protection, or whether it falls within the open fields doctrine.
Holding
The barn was outside the curtilage; it was in the open fields and not protected by the Fourth Amendment.
Rule / Doctrine
The Court articulated a four-factor test for determining curtilage: (1) the proximity of the area to the home; (2) whether it is included within an enclosure surrounding the home; (3) the nature of the use of the area; and (4) the steps taken by the resident to protect the area from observation. Applying those factors, the barn was not within curtilage because it was distant from the house, not included in the home’s enclosure, and not regularly used for intimate activities.
Significance
Operationalized the curtilage concept from Oliver v. United States by providing a four-factor analytical framework that courts still use to determine whether an area adjacent to a home is curtilage (protected) or open field (unprotected).
