United States v. Place

Case Date: 11/04/1983

United States v. Place, 462 U.S. 696 (1983) was a decision by the Supreme Court of the United States, which held that a sniff by a police dog specially trained to detect the presence of narcotics is not a "search" under the meaning of the Fourth Amendment to the United States Constitution. The Court reasoned that the sniff of a dog is sui generis, intended to reveal only the presence or absence of narcotics. Because a dog sniff is so limited a test, the Court carved out this exception from the broad category of "searches" for which a warrant is generally required.
