During prohibition, officers arranged an undercover purchase of liquor from George Carroll, an illicit dealer under investigation, but the transaction was not completed. They later saw Carroll and John Kiro driving on the highway from DetroittoGrand Rapids, Michigan, which they regularly patrolled. They pursued them, pulled them over, and searched the car, finding illegal liquor behind the rear seat.
The National Prohibition Act provided that officers could make warrantless searches of vehicles, boats, or airplanes when they had reason to believe illegal liquor was being transported and that law enforced the Eighteenth Amendment.[1]
The Court noted that Congress early observed the need for a search warrant in non-border search situations,[2] and Congress always recognized "a necessary difference" between searches of buildings and vehicles "for contraband goods, where it is not practical to secure a warrant, because the vehicle can be quickly moved out of the locality or jurisdiction in which the warrant must be sought."[3] The warrantless search was thus valid.
The Court held, however,
It would be intolerable and unreasonable if a prohibition agent were authorized to stop every automobile on the chance of finding liquor, and thus subject all persons lawfully using the highways to the inconvenience and indignity of such a search.... [T]hose lawfully within the country, entitled to use the public highways, have a right to free passage without interruption or search unless there is known to a competent official, authorized to search, probable cause for believing that their vehicles are carrying contraband or illegal merchandise.[4]
The Court added that where the securing of a warrant is reasonably practicable, it must be used.[5]
That became known as the Carroll doctrine: a vehicle could be searched without a search warrant if there was probable cause to believe that evidence is present in the vehicle, coupled with exigent circumstances to believe that the vehicle could be removed from the area before a warrant could be obtained.[6]
Underneath their opinion, the majority included a note that Justice Joseph McKenna concurred with them before his retirement earlier in the year.[7]
Justices James Clark McReynolds and George Sutherland filed a dissenting opinion. In brief, they believed that the fact that the case involved bootleggers was prejudicial yet not a justification for creating a broad exception to unreasonable search doctrine.[8]
In 1927, the Florida Legislature enacted the Carroll decision into statute law in Florida, and the statute remains in effect.[9]
InUnited States v. Di Re,[10] the Court declined to extend Carroll to permit searches of passengers in a vehicle that had apparently been lawfully stopped. In Di Re there was no probable cause to believe that the passenger was holding any evidence.
The Court relied on CarrollinCooper v. California[11] to observe that a search of a vehicle may be reasonable where the same search of a dwelling may not be reasonable.
^Carroll v. United States, 267U.S.132, 144 (1925). The National Prohibition Act required a search warrant for a search of a building. However, this law was revoked in 1933 when Prohibition ended.
^267 U.S. at 156. Observation: This comment is no longer valid. See Pennsylvania v. Labron, 518U.S.938 (1996) ("If a car is readily mobile and probable cause exists to believe it contains contraband, the Fourth Amendment thus permits police to search the vehicle without more," citing California v. Carney, 471U.S.386, 393 (1985); Maryland v. Dyson, 527U.S.465 (1999).
^InHusty v. United States, 282U.S.694 (1931), a vehicle search was sustained under Carroll where the officers had probable cause to believe a vehicle contained liquor, but they waited until the driver showed up to arrest him and search the car. The Court thus rejected Husty's contention that the search was invalid since the police could have obtained a warrant under the circumstances. Husty, 282 U.S. at 701.
