Arizona v. Hicks

Arizona v. Hicks was a 1987 decision by the United States Supreme Court that held that the Fourth Amendment requires the police to have probable cause to seize items in plain view.

Background
On 18 April 1984, a bullet was fired through the floor of Hicks' apartment, striking and injuring a man in the apartment below. The police arrived and entered Hicks' apartment to search for the shooter, for other victims, and for weapons. While in Hicks's apartment, one of the officers noticed two sets of expensive-looking stereo equipment, "which seemed out of place in the squalid and otherwise ill-appointed four-room apartment." The officer moved the equipment to record the serial numbers, suspecting that the equipment was stolen, and then reported the serial numbers to police headquarters. The officer was informed that the equipment had been taken in an armed robbery, for which Hicks was later indicted.

The state trial court granted Hicks' motion to suppress the stereo equipment, and the Arizona Court of Appeals affirmed. It was conceded that the police's initial entry into Hicks' apartment was lawful, although it took place without a warrant, because of the emergency created by the shooting. But moving the stereo equipment was an additional search, the appellate court reasoned, which lacked a warrant and was unrelated to the purpose the police were in Hicks' apartment to begin with. The appellate court therefore found that the police's actions violated the Fourth Amendment, and affirmed the trial court's granting of the motion to suppress. The Arizona Supreme Court declined the State's request to review the case, but the United States Supreme Court agreed to do so.

Result
The Fourth Amendment guards against unreasonable "searches" and "seizures." The Court first ruled that when the police officer moved the stereo equipment to record the serial numbers, he conducted a Fourth Amendment "search." This search was unrelated to the initial reason the police were in Hicks's apartment—to search for weapons and the person who fired the bullet through the floor of the apartment.

The Court rejected the "apparent position of the Arizona Court of Appeals that because the officers' action directed to the stereo equipment was unrelated to the justification for their entry into [Hicks's] apartment, it was per se unreasonable." The State was attempting to justify the search under the plain view exception to the warrant requirement; in such cases, the search is by definition unrelated to the initial purpose the police are in the position to view the purported contraband or evidence of criminal activity.

Rather, the purpose of the plain-view exception to the warrant requirement is to spare the police who discover weapons or contraband during the course of an otherwise lawful search the trouble of having to obtain a warrant to seize those weapons or contraband. Warrants only issue upon a showing of probable cause; thus, probable cause to believe an item in plain view is contraband or evidence of criminal activity must be required, to allow the plain-view exception.

There are, of course, other situations in which the police may lawfully seize an object upon less than probable cause. But the State justified the search of the stereo equipment in this case solely on the fact that they were in plain view of the officers who were otherwise lawfully present in Hicks's apartment, and that happenstance cannot by itself supplant the requirement of probable cause.
