Held: The Fourth Amendment was not violated by the naked-eye aerial observation of respondent's backyard. Pp. 476 U. S. 211-215.
(a) The touchstone of Fourth Amendment analysis is whether a person has a constitutionally protected reasonable expectation of privacy, which involves the two inquiries of whether the individual manifested a subjective expectation of privacy in the object of the challenged search, and whether society is willing to recognize that expectation as reasonable. Ratz v. United States, 389 U. S. 347. In pursuing the second inquiry, the test of legitimacy is not whether the individual chooses to conceal assertedly "private activity," but whether the government's intrusion infringes upon the personal and societal values protected by the Fourth Amendment. Pp. 476 U. S. 211-212.
readily discernible to the naked eye as marijuana, and it was irrelevant that the observation from the airplane was directed at identifying the plants and that the officers were trained to recognize marijuana. Any member of the public flying in this airspace who cared to glance down could have seen everything that the officers observed. The Fourth Amendment simply does not require police traveling in the public airways at 1,000 feet to obtain a warrant in order to observe what is visible to the naked eye. Pp. 476 U. S. 212-215.
161 Cal.App.3d 1081, 208 Cal.Rptr. 93, reversed.
BURGER, C.J., delivered the opinion of the Court, in which WHITE, REHNQUIST, STEVENS, and O'CONNOR, JJ., joined. POWELL, J., filed a dissenting opinion, in which BRENNAN, MARSHALL, and BLACKMUN, JJ., joined, post, p. 476 U. S. 215.
executed the next day, and 73 plants were seized; it is not disputed that these were marijuana.
After the trial court denied respondent's motion to suppress the evidence of the search, respondent pleaded guilty to a charge of cultivation of marijuana. The California Court of Appeal reversed, however, on the ground that the warrantless aerial observation of respondent's yard which led to the issuance of the warrant violated the Fourth Amendment. 161 Cal.App.3d 1081, 208 Cal.Rptr. 93 (1984). That court held first that respondent's backyard marijuana garden was within the "curtilage" of his home, under Oliver v. United States, 466 U. S. 170 (1984). The court emphasized that the height and existence of the two fences constituted "objective criteria from which we may conclude he manifested a reasonable expectation of privacy by any standard." 161 Cal.App.3d at 1089, 208 Cal.Rptr. at 97.
"was not the result of a routine patrol conducted for any other legitimate law enforcement or public safety objective, but was undertaken for the specific purpose of observing this particular enclosure within [respondent's] curtilage."
The State argues that respondent has "knowingly exposed" his backyard to aerial observation, because all that was seen was visible to the naked eye from any aircraft flying overhead. The State analogizes its mode of observation to a knothole or opening in a fence: if there is an opening, the police may look.
Clearly -- and understandably -- respondent has met the test of manifesting his own subjective intent and desire to maintain privacy as to his unlawful agricultural pursuits. However, we need not address that issue, for the State has not challenged the finding of the California Court of Appeal that respondent had such an expectation. It can reasonably be assumed that the 10-foot fence was placed to conceal the marijuana crop from at least street-level views. So far as the normal sidewalk traffic was concerned, this fence served that purpose, because respondent "took normal precautions to maintain his privacy." Rawlings v. Kentucky, 448 U. S. 98, 448 U. S. 105 (1980).
a subjective expectation of privacy from all observations of his backyard, or whether instead he manifested merely a hope that no one would observe his unlawful gardening pursuits, is not entirely clear in these circumstances. Respondent appears to challenge the authority of government to observe his activity from any vantage point or place if the viewing is motivated by a law enforcement purpose, and not the result of a casual, accidental observation.
We turn, therefore, to the second inquiry under Katz, i.e., whether that expectation is reasonable. In pursuing this inquiry, we must keep in mind that "[t]he test of legitimacy is not whether the individual chooses to conceal assertedly private' activity," but instead "whether the government's intrusion infringes upon the personal and societal values protected by the Fourth Amendment." Oliver, supra, at 466 U. S. 181-183.
Respondent argues that, because his yard was in the curtilage of his home, no governmental aerial observation is permissible under the Fourth Amendment without a warrant. [Footnote 1] The history and genesis of the curtilage doctrine are instructive.
"At common law, the curtilage is the area to which extends the intimate activity associated with the 'sanctity of a man's home and the privacies of life.'"
protection afforded the curtilage is essentially a protection of families and personal privacy in an area intimately linked to the home, both physically and psychologically, where privacy expectations are most heightened. The claimed area here was immediately adjacent to a suburban home, surrounded by high double fences. This close nexus to the home would appear to encompass this small area within the curtilage. Accepting, as the State does, that this yard and its crop fall within the curtilage, the question remains whether naked-eye observation of the curtilage by police from an aircraft lawfully operating at an altitude of 1,000 feet violates an expectation of privacy that is reasonable.
That the area is within the curtilage does not itself bar all police observation. The Fourth Amendment protection of the home has never been extended to require law enforcement officers to shield their eyes when passing by a home on public thoroughfares. Nor does the mere fact that an individual has taken measures to restrict some views of his activities preclude an officer's observations from a public vantage point where he has a right to be and which renders the activities clearly visible. E.g., United States v. Knotts, 460 U. S. 276, 460 U. S. 282 (1983). "What a person knowingly exposes to the public, even in his own home or office, is not a subject of Fourth Amendment protection." Katz, supra, at 389 U. S. 351.
The dissent contends that the Court ignores Justice Harlan's warning in his concurrence in Katz v. United States, 389 U.S. at 389 U. S. 361-362, that the Fourth Amendment should not be limited to proscribing only physical intrusions onto private property. Post at 476 U. S. 215-216. But Justice Harlan's observations about future electronic developments and the potential for electronic interference with private communications, see Katz, supra, at 389 U. S. 362, were plainly not aimed at simple visual observations from a public place. Indeed, since Katz, the Court has required warrants for electronic surveillance aimed at intercepting private conversations. See United States v. United States District Court, 407 U. S. 297 (1972).
"a man's home is, for most purposes, a place where he expects privacy, but objects, activities, or statements that he exposes to the 'plain view' of outsiders are not 'protected,' because no intention to keep them to himself has been exhibited. On the other hand, conversations in the open would not be protected against being overheard, for the expectation of privacy under the circumstances would be unreasonable."
Katz, supra, at 389 U. S. 361.
Because the parties framed the issue in the California courts below and in this Court as concerning only the reasonableness of aerial observation generally, see Pet. for Cert. i, without raising any distinct issue as to the photograph attached as an exhibit to the affidavit in support of the search warrant, our analysis is similarly circumscribed. It was the officer's observation, not the photograph, that supported the warrant. Officer Shutz testified that the photograph did not identify the marijuana as such, because it failed to reveal a "true representation" of the color of the plants: "you have to see it with the naked eye." App. 36.
The California Court of Appeal recognized that police have the right to use navigable airspace, but made a pointed distinction between police aircraft focusing on a particular home and police aircraft engaged in a "routine patrol." It concluded that the officers' "focused" observations violated respondent's reasonable expectations of privacy. In short, that court concluded that a regular police patrol plane identifying respondent's marijuana would lead to a different result. Whether this is a rational distinction is hardly relevant, although we find difficulty understanding exactly how respondent's expectations of privacy from aerial observation might differ when two airplanes pass overhead at identical altitudes, simply for different purposes. We are cited to no authority for this novel analysis or the conclusion it begat. The fact that a ground-level observation by police "focused" on a particular place is not different from a "focused" aerial observation under the Fourth Amendment.
"[a]erial observation of curtilage may become invasive, either due to physical intrusiveness or through modern technology which discloses to the senses those intimate associations, objects or activities otherwise imperceptible to police or fellow citizens."
JUSTICE POWELL, with whom JUSTICE BRENNAN, JUSTICE MARSHALL, and JUSTICE BLACKMUN join, dissenting.
"is, in the present day, bad physics as well as bad law, for reasonable expectations of privacy may be defeated by electronic as well as physical invasion."
Id. at 389 U. S. 362. Because the Court today ignores that warning in an opinion that departs significantly from the standard developed in Katz for deciding when a Fourth Amendment violation has occurred, I dissent.
As the Court's opinion reflects, the facts of this case are not complicated. Officer Shutz investigated an anonymous report that marijuana was growing in the backyard of respondent's home. A tall fence prevented Shutz from looking into the yard from the street. The yard was directly behind the home, so that the home itself furnished one border of the fence. Shutz proceeded, without obtaining a warrant, to charter a plane and fly over the home at an altitude of 1,000 feet. Observing marijuana plants growing in the fenced-in yard, Shutz photographed respondent's home and yard, as well as homes and yards of neighbors. The photograph clearly shows that the enclosed yard also contained a small swimming pool and patio. Shutz then filed an affidavit, to which he attached the photograph, describing the anonymous tip and his aerial observation of the marijuana. A warrant issued, [Footnote 2/1] and a search of the yard confirmed Shutz' aerial observations. Respondent was arrested for cultivating marijuana, a felony under California law.
rejects that contention, holding that respondent's expectation of privacy in the curtilage of his home, although reasonable as to intrusions on the ground, was unreasonable as to surveillance from the navigable airspace. In my view, the Court's holding rests on only one obvious fact, namely, that the airspace generally is open to all persons for travel in airplanes. The Court does not explain why this single fact deprives citizens of their privacy interest in outdoor activities in an enclosed curtilage.
Boyd v. United States, 116 U. S. 616, 116 U. S. 635 (1886). Since the landmark decision in Katz v. United States, the Court has fulfilled its duty to protect Fourth Amendment rights by asking if police surveillance has intruded on an individual's reasonable expectation of privacy.
407 U. S. 312-313 (footnote omitted), the Court in Katz abandoned its inquiry into whether police had committed a physical trespass. Katz announced a standard under which the occurrence of a search turned not on the physical position of the police conducting the surveillance, but on whether the surveillance in question had invaded a constitutionally protected reasonable expectation of privacy.
Our decisions following the teaching of Katz illustrate that this inquiry "normally embraces two discrete questions." Smith v. Maryland, 442 U. S. 735, 442 U. S. 740 (1979). "The first is whether the individual, by his conduct, has exhibited an actual (subjective) expectation of privacy.'" Ibid., quoting Katz v. United States, 389 U.S. at 389 U. S. 361 (Harlan, J., concurring). The second is whether that subjective expectation "is `one that society is prepared to recognize as "reasonable."'" 442 U.S. at 442 U. S. 740, quoting Katz v. United States, supra, at 389 U. S. 361 (Harlan, J., concurring). While the Court today purports to reaffirm this analytical framework, its conclusory rejection of respondent's expectation of privacy in the yard of his residence as one that "is unreasonable," ante at 476 U. S. 213, represents a turning away from the principles that have guided our Fourth Amendment inquiry. The Court's rejection of respondent's Fourth Amendment claim is curiously at odds with its purported reaffirmation of the curtilage doctrine, both in this decision and its companion case, Dow Chemical Co. v. United States, post p. 476 U. S. 227, and particularly with its conclusion in Dow that society is prepared to recognize as reasonable expectations of privacy in the curtilage, post at 476 U. S. 235.
The second question under Katz has been described as asking whether an expectation of privacy is "legitimate in the sense required by the Fourth Amendment." [Footnote 2/4] Oliver v.
"the Court has given weight to such factors as the intention of the Framers of the Fourth Amendment, . . . the uses to which the individual has put a location, . . . and our societal understanding that certain areas deserve the most scrupulous protection from government invasion. [Footnote 2/5]"
Id. at 466 U. S. 178. Our decisions have made clear that this inquiry often must be decided by "reference to a place,'" Katz v. United States, supra, at 389 U. S. 361 (Harlan, J., concurring); see Payton v. New York, 445 U.S. at 445 U. S. 589, and that a home is a place in which a subjective expectation of privacy virtually always will be legitimate, ibid.; see, e.g., United States v. Karo, 468 U. S. 705, 468 U. S. 713-715 (1984); Steagald v. United States, 451 U.S. at 451 U. S. 211-212.
"At the very core [of the Fourth Amendment] stands the right of a [person] to retreat into his own home and there be free from unreasonable governmental intrusion."
Silverman v. United States, 365 U. S. 505, 365 U. S. 511 (1961).
decided today, the Court reaffirms that the "curtilage doctrine evolved to protect much the same kind of privacy as that covering the interior of a structure." Post at 476 U. S. 235. The Court in Dow emphasizes, moreover, that society accepts as reasonable citizens' expectations of privacy in the area immediately surrounding their homes. Ibid.
"have defined the curtilage, as did the common law, by reference to the factors that determine whether an individual reasonably may expect that an area immediately adjacent to the home will remain private. See, e.g., United States v. Van Dyke, 643 F.2d 992, 993-994 (CA4 1981); United States v. Williams, 581 F.2d 451, 453 (CA5 1978); Care v. United States, 231 F.2d 22, 25 (CA10), cert. denied, 351 U.S. 932 (1956)."
Oliver v. United States, supra, at 466 U. S. 180. The lower federal courts have agreed that the curtilage is "an area of domestic use immediately surrounding a dwelling and usually, but not always, fenced in with the dwelling." [Footnote 2/6] United States v. LaBerge, 267 F.Supp. 686, 692 (Md.1967); see United States v. Van Dyke, 643 F.2d 992, 993, n. 1 (CA4 1984). Those courts also have held that whether an area is within the curtilage must be decided by looking at all of the facts. Ibid., citing Care v. United States, supra, at 25. Relevant facts include the proximity between the area claimed to be curtilage and the home, the nature of the uses to which the area is put, and the steps taken by the resident to protect the area from observation by people passing by. See Care v. United States, supra, at 25; see also United States v. Van Dyke, supra, at 993-994.
The Court begins its analysis of the Fourth Amendment issue posed here by deciding that respondent had an expectation of privacy in his backyard. I agree with that conclusion because of the close proximity of the yard to the house, the nature of some of the activities respondent conducted there, [Footnote 2/7] and because he had taken steps to shield those activities from the view of passersby. The Court then implicitly acknowledges that society is prepared to recognize his expectation as reasonable with respect to ground-level surveillance, holding that the yard was within the curtilage, an area in which privacy interests have been afforded the "most heightened" protection. Ante at 476 U. S. 213. As the foregoing discussion of the curtilage doctrine demonstrates, respondent's yard unquestionably was within the curtilage. Since Officer Shutz could not see into this private family area from the street, the Court certainly would agree that he would have conducted an unreasonable search had he climbed over the fence, or used a ladder to peer into the yard without first securing a warrant. See United States v. Van Dyke, supra; see also United States v. Williams, 581 F.2d 451 (CA5 1978).
respondent's yard. It then relies on the fact that the surveillance was not accompanied by a physical invasion of the curtilage, ibid. Reliance on the manner of surveillance is directly contrary to the standard of Katz, which identifies a constitutionally protected privacy right by focusing on the interests of the individual and of a free society. Since Katz, we have consistently held that the presence or absence of physical trespass by police is constitutionally irrelevant to the question whether society is prepared to recognize an asserted privacy interest as reasonable. E.g., United States v. United States District Court, 407 U.S. at 407 U. S. 313.
The Court's holding, therefore, must rest solely on the fact that members of the public fly in planes and may look down at homes as they fly over them. Ante at 476 U. S. 213-214. The Court does not explain why it finds this fact to be significant. One may assume that the Court believes that citizens bear the risk that air travelers will observe activities occurring within backyards that are open to the sun and air. This risk, the Court appears to hold, nullifies expectations of privacy in those yards even as to purposeful police surveillance from the air. The Court finds support for this conclusion in United States v. Knotts, 460 U. S. 276 (1983). Ante at 476 U. S. 213.
private activities, and might connect those activities with particular people, is simply too trivial to protect against. It is no accident that, as a matter of common experience, many people build fences around their residential areas, but few build roofs over their backyards. Therefore, contrary to the Court's suggestion, ante at 476 U. S. 213, people do not "knowingly expos[e]'" their residential yards "`to the public'" merely by failing to build barriers that prevent aerial surveillance.
Since respondent had a reasonable expectation of privacy in his yard, aerial surveillance undertaken by the police for the purpose of discovering evidence of crime constituted a "search" within the meaning of the Fourth Amendment. "Warrantless searches are presumptively unreasonable, though the Court has recognized a few limited exceptions to this general rule." United States v. Karo, 468 U.S. at 468 U. S. 717. This case presents no such exception. The indiscriminate nature of aerial surveillance, illustrated by Officer Shutz' photograph of respondent's home and enclosed yard as well as those of his neighbors, poses "far too serious a threat to privacy interests in the home to escape entirely some sort of Fourth Amendment oversight." Id. at 468 U. S. 716 (footnote omitted). Therefore, I would affirm the judgment of the California Court of Appeal ordering suppression of the marijuana plants.
States, 116 U.S. at 116 U. S. 635. But this Court recognized long ago that the essence of a Fourth Amendment violation is "not the breaking of [a person's] doors, and the rummaging of his drawers," but rather is "the invasion of his indefeasible right of personal security, personal liberty and private property." Id. at 116 U. S. 630. Rapidly advancing technology now permits police to conduct surveillance in the home itself, an area where privacy interests are most cherished in our society, without any physical trespass. While the rule in Katz was designed to prevent silent and unseen invasions of Fourth Amendment privacy rights in a variety of settings, we have consistently afforded heightened protection to a person's right to be left alone in the privacy of his house. The Court fails to enforce that right or to give any weight to the longstanding presumption that warrantless intrusions into the home are unreasonable. [Footnote 2/11] I dissent.
The warrant authorized Shutz to search the home and its attached garage, as well as the yard, for marijuana, narcotics paraphernalia, records relating to marijuana sales, and documents identifying the occupant of the premises.
See, e.g., Payton v. New York, 445 U. S. 573, 445 U. S. 583-585, n. 20 (1980).
"[T]he search of one's home or office no longer requires physical entry, for science has brought forth far more effective devices for the invasion of a person's privacy than the direct and obvious methods of oppression which were detested by our forbears, and which inspired the Fourth Amendment. . . . Whether the search of private quarters is accomplished by placing on the outer walls of the sanctum a detectaphone that transmits to the outside listener the intimate details of a private conversation, or by new methods of photography that penetrate walls or overcome distances, the privacy of the citizen is equally invaded by the Government, and intimate personal matters are laid bare to view."
Goldman v. United States, 316 U. S. 129, 316 U. S. 139 (1942) (Murphy, J., dissenting). Since 1942, science has developed even more sophisticated means of surveillance.
In Justice Harlan's classic description, an actual expectation of privacy is entitled to Fourth Amendment protection if it is an expectation that society recognizes as "reasonable." Katz v. United States, 3899 U.S. at 389 U. S. 361 (Harlan, J., concurring). Since Katz, our decisions also have described constitutionally protected privacy interests as those that society regards as "legitimate," using the words "reasonable" and "legitimate" interchangeably. E.g., Oliver v. United States, 466 U. S. 170 (1984); Rakas v. Illinois, 439 U. S. 128, 439 U. S. 143-144, n. 12 (1978).
"Legitimation of expectations of privacy by law must have a source outside of the Fourth Amendment, either by reference to concepts of real or personal property law or to understandings that are recognized and permitted by society."
Ibid. This inquiry necessarily focuses on personal interests in privacy and liberty recognized by a free society.
"a small court, yard, garth, or piece of ground attached to a dwelling-house, and forming one enclosure with it, or so regarded by the law; the area attached to and containing a dwelling-house and its out-buildings."
2 Oxford English Dictionary 1278 (1933).
The Court omits any reference to the fact that respondent's yard contained a swimming pool and a patio for sunbathing and other private activities. At the suppression hearing, respondent sought to introduce evidence showing that he did use his yard for domestic activities. The trial court refused to consider that evidence. Tr. on Appeal 5-8 (Aug. 16, 1983).
Of Course, during takeoff and landing, planes briefly fly at low enough altitudes to afford fleeting opportunities to observe some types of activity in the curtilages of residents who live within the strictly regulated takeoff and landing zones. As all of us know from personal experience, at least in passenger aircrafts, there rarely -- if ever -- is an opportunity for a practical observation and photographing of unlawful activity similar to that obtained by Officer Shutz in this case. The Court's analogy to commercial and private overflights, therefore, is wholly without merit.
Some of our precedents have held that an expectation of privacy was not reasonable in part because the individual had assumed the risk that certain kinds of private information would be turned over to the police. United States v. Miller, 425 U. S. 435, 425 U. S. 443 (1976). None of the prior decisions of this Court is a precedent for today's decision. As JUSTICE MARSHALL has observed, it is our duty to be sensitive to the risks that a citizen "should be forced to assume in a free and open society." Smith v. Maryland, 442 U. S. 735, 442 U. S. 750 (1979) (dissenting opinion).
The Court's decision has serious implications for outdoor family activities conducted in the curtilage of a home. The feature of such activities that makes them desirable to citizens living in a free society, namely, the fact that they occur in the open air and sunlight, is relied on by the Court as a justification for permitting police to conduct warrantless surveillance at will. Aerial surveillance is nearly as intrusive on family privacy as physical trespass into the curtilage. It would appear that, after today, families can expect to be free of official surveillance only when they retreat behind the walls of their homes.
Of course, the right of privacy in the home and its curtilage includes no right to engage in unlawful conduct there. But the Fourth Amendment requires police to secure a warrant before they may intrude on that privacy to search for evidence of suspected crime. United States v. Karo, 468 U. S. 705, 468 U. S. 713-715 (1984).
