OPINION
GRODIN, J.—We recently concluded that, unless a warrant is obtained, our state Constitution forbids intensive aerial inspection of an individual enclosed backyard based on prior suspicions that marijuana cultivation will be found within the enclosure. (People v. Cook (1985) 41 Cal.3d 373 [221 Cal.Rptr. 499, 710 P.2d 299].)1 In this case, we confront a different type of police activity. Under a program designed to curb widespread commercial marijuana farming in rural and semirural areas, law enforcement officials took to the air, in fixed-wing aircraft, to identify the locations of marijuana crops being grown in open fields. Flying at elevations from which the details of human activity could not be observed, they saw indications of what they believed to be marijuana growing in a remote area. While there were signs of human habitation nearby, and the officers took photographs to show the relationship between that habitation and the growing crop, it was the crop in the open field, and not defendant‘s residence or curtilage,
While we uphold the instant search on its facts, we recognize that a random surveillance and eradication program presents difficult constitutional and regulatory problems. Certain practices of the program operating in defendant‘s locale have already led to a successful class injunction suit. We invite the Legislature to participate in establishing standards which will balance the needs of law enforcement against the legitimate privacy expectations of affected citizens.
FACTS
Aerial surveillance by the police revealed what they suspected were marijuana gardens growing on appellant Mayoff‘s land. Based on the aerial views, the police obtained a warrant for a ground search of the property. Under its authority, they seized a portion of appellant‘s marijuana crop. He was charged with one count of cultivation of marijuana. (
The surveillance which led to discovery of appellant‘s crop was part of a program operated in several rural northern California counties where widespread commercial marijuana farming has taken root. The program is run jointly by local, state, and federal law enforcement personnel; it has been in effect in Humboldt County, where appellant resides, for approximately eight years. Fundamental to the scheme is a random pattern of warrantless flights over the entire county, focusing on rural areas. The flights are undertaken for the purpose of identifying plots of land on which it appears marijuana is being cultivated.2 The viewing officers note such factors as the
Much of Humboldt County‘s terrain is extremely rugged and isolated. Appellant, like roughly one-tenth of the county‘s rural population of about 29,000, lives in territory so remote that it can be examined only from the air. His 40-acre parcel is in a mountainous, wooded region, almost a mile from the nearest paved road. It cannot be seen from the road, and is connected to it by a dirt path which winds its way toward the portion of the property on which appellant resides. Only the top of one of appellant‘s buildings is visible from the path, which abruptly ends shortly after connecting with a turnoff to his residence. This turnoff is so rocky it is difficult to traverse without benefit of a four-wheel-drive vehicle.
On July 23, 1980, Agent Brown of the California Department of Justice and Detective Vulich of the Humboldt County Sheriff‘s Department made an antimarijuana surveillance flight from Eureka to the Garberville area in southern Humboldt County. They had no search warrant and no prior suspicion marijuana was being grown on appellant‘s property. From an altitude of at least 1,000 feet, one of the officers noticed what he believed to be marijuana growing on appellant‘s land.
Nearly two weeks later, on August 4, 1980, Detective Vulich flew again over appellant‘s property in order to photograph the land below. Again, it appears that an altitude between 1,000 and 2,000 feet was maintained. Vulich still had nо search warrant. Apparently using an 80-200 millimeter telephoto lens, he photographed the suspicious vegetation, two trailers parked on the property, and the surrounding area. On his return to police headquarters he showed the snapshots to Agent Brown, who then executed an affidavit in support of a search warrant. On August 15, 1980, the warrant
The aerial photographs introduced in evidence indicate that the gardens were at least 200 feet from the closest of the trailers. No fences formed a common enclosure around the trailers and the garden area.
DISCUSSION
1. Warrantless aerial surveillance.
In California, the legality of a warrantless police intrusion into allegedly private zones of activity depends on whether the government has “unreasonably” invaded an actual expectation of privacy which society is prepared to recognize as reasonable. (E.g., Cook, supra, 41 Cal.3d at p. 379; Lorenzana v. Superior Court (1973) 9 Cal.3d 626, 638 [108 Cal.Rptr. 585, 511 P.2d 33]; see Katz v. United States (1967) 389 U.S. 347, 350-352 [19 L.Ed.2d 576, 581-583, 88 S.Ct. 507].) All parties concede that defendant sought privacy for his residence and his marijuana gardens. They were on his private property in a remote area, away from ground-level vantage points open to the public. The gardens themselves, while not immediately adjacent to the residential structures, were carefully enclosed by fences and trees. The only issues, therefore, are whether defendant‘s wishes were objectively reasonable and, if so, whether the warrantless aerial observation invaded his expectations unreasonably.
Three recent cases bear on these questions but do not resolve them. The first such decision is United States v. Oliver (1984) 466 U.S. 170 [80 L.Ed.2d 214, 104 S.Ct. 1735]. In two separate incidents there under review, law enforcement agents, acting without warrants or probable cause, entered remote rural private property to look for marijuana cultivation. Noting that the land inspected in each instance was some distance from any home or business, the high court found no violation of the Fourth Amendment.
The Oliver majority conceded that the Fourth Amendment provides a high degree of privacy protection to the “curtilage” of a residence—“the land immediately surrounding and associated with the home.” (P. 180 [80 L.Ed.2d p. 225].) However, it affirmed the long-standing rule (see Hester v. United States (1924) 265 U.S. 57 [68 L.Ed. 898, 44 S.Ct. 445]) that the federal Constitution allows the authorities to inspect areas beyond the curtilage—so-called “open fields“—at will, even where they trespass on private
The five majority justices concluded that open fields are not among the “persons, houses, papers, and effects” dеscribed in the Fourth Amendment. (Pp. 176-177 [80 L.Ed.2d p. 223]; see Hester, supra, 265 U.S. at p. 59 [68 L.Ed. at p. 900].) Moreover, the Oliver majority reasoned, society is not prepared to recognize such areas as protected zones of intimate privacy, even where the individuals who seek privacy in such places have made that intention clear. (466 U.S. at pp. 179-184 [80 L.Ed.2d at pp. 224-228].)3 Under Oliver, police observation of an open field, at least from the ground, simply is not a “search” subject to federal constitutional limitations.4
In Cook, supra, we subsequently confirmed that the California Constitution, like its federal counterpart, protects with special zeal the legitimate expectation of privacy within a residential curtilage. Law enforcement agents may not defeat that expectation, we ruled, by spying at will on a private yard from an aircraft.
We were not persuaded that police officers who examine a residence from the air are simply observing what is in “plain view” from a lawful public vantage point. Such reasoning, we explained, ignores the essential difference between ground and aerial surveillance. One can take reasonable steps to ensure his yard‘s privacy from the street, sidewalk, or neighborhood, and police on the ground may not broach such barriers to gain a view of the enclosed area. But there is no practical defense against aerial spying, and precious constitutional privacy rights would mean little if the government could defeat them so еasily.
Even if members of the public may casually see into his yard when a routine flight happens over the property, we concluded, a householder does not thereby consent to focused examination of the curtilage by airborne police officers looking for evidence of crime. No law enforcement interest justifies such intensive warrantless government intrusion into a zone of heightened constitutional privacy. (41 Cal.3d at pp. 379-385.)
In Ciraolo, as in Cook, one convicted on a marijuana charge urged that the police violated his constitutional rights when they examined his enclosed backyard from an airplane to confirm vague suspicions that he was engaged in illegal cultivation. Over a vigorous dissent, a bare majority of the high court disagreed. However private the curtilage in other contexts, the majority said, the realities of air travel force a modern householder to assume that his yard and anything in it are in plain view from the air. (476 U.S. at pp. 211-215 [90 L.Ed.2d at pp. 215-218] [see also dis. opn. by Powell, J., at pp. 216 et seq. (90 L.Ed.2d at pp. 218 et seq.)]; cf., Dow Chemical Co. v. United States (1986) 476 U.S. 227 [90 L.Ed.2d 226, 106 S.Ct. 1819].)
Our state charter is a “document of independent force” (People v. Brisendine (1975) 13 Cal.3d 528, 549-550 [119 Cal.Rptr. 315, 531 P.2d 1099]), and its guarantees “are not dependent on those [provided] by the United States Constitution” unless a contrary intent appears. (
Having carefully examined the majority decisions in Ciraolo and Dow Chemical, cited supra, we find ourselves unconvinced by their reasoning. We adhere to our holding in Cook. The question remains whether the federal and state Constitutions nonetheless permit the “random” rural aerial surveillance at issue in this case.
Before Oliver was decided, California courts displayed some uncertainty about whether the “open fields” doctrine had survived the intervening principle of Katz, supra, that “the [Constitution] protects people, not places” and may shield “what [a person] seeks to preserve as private, even in an area accessible to the public . . . .” (389 U.S. at p. 350 [19 L.Ed.2d at p. 582]; compare, e.g., People v. Krivda (1971) 5 Cal.3d 357, 364-365
However, pre-Oliver California cases consistently upheld warrantless surveillance of rural marijuana gardens from airplanes flying at normal altitudes, even when surveillance was part of a “random” overflight program, employed optical aids, and inspected homes or human activities near the gardens. Interpreting Katz in a manner which anticipated Oliver, the Courts of Appeal reasoned that common habits in the use of agricultural and woodland property preclude any reasonable expectation that crops growing there will not be seen from legal aerial vantage points by the public or the police. (Dean v. Superior Court (1973) 35 Cal.App.3d 112, 114, 117 [110 Cal.Rptr. 585] [patch located “in an isolated area of the Sierra foothills, . . . hidden from view by the surrounding hills and woods“]; see also People v. Egan (1983) 141 Cal.App.3d 798, 800, 806 [190 Cal.Rptr. 546] [overflight of ranch prompted by rumors of marijuana cultivation; “[t]he appellate courts of this state have consistently upheld aerial surveillance from lawful altitudes over rural and relatively unpopulated property. . . .“]; Tuttle v.

Courts in other jurisdictions have applied similar principles to uphold, under a wide variety of circumstances, warrantless aerial surveillance for marijuana in rural areas. (United States v. Allen (9th Cir. 1980) 675 F.2d 1373, 1380-1381, cert. den.

For state as well as federal purposes, we accept Oliver‘s premise that there is a greater legitimate expectation of privacy within the home and curtilage than in “open fields.” We agree that the “curtilage,” under both the state and federal Constitutions, is confined to those outdoor areas “immediately adjacent to the home” to which extend “the intimate activity associated with the ‘sanctity of a [person‘s] home and the privacies of life’ [citation omitted] . . .“; outdoor places beyond this adjacent and intimate
Moreover, we conclude, as prior cases have suggested, that there can be no reasonаble expectation of absolute privacy from warrantless aerial surveillance by the police of crops growing in open fields. Insofar as the open fields are observed from sufficient altitude to prevent disruption or detailed observation of individual activities below, the fields are in “plain view” from the air, and aerial surveillance for illegal cultivation there is not a “search” governed by either Constitution.5
In our view, the crop at issue here lay outside the curtilage, in an open field. We recognize that some decisions have defined rural curtilages expansively. Yet we are not persuaded that the cultivation which drew the officers’ attention here was within a zone of heightened privacy.
The suspicious vegetation was seen in a secluded, mountainous area, some 200 or more feet from trailers which might be residences. While the cultivated area was shielded from ground-level vantage points outside appellant‘s property, it was not in an area “immediately adjacent” to the trailers “to which . . . the intimate activity associated with the ‘sanctity of a man‘s home and the privacies of life’ could be expected to extend.” There was no physical indication, such as a common enclosure, that the trailers and gardens were considered a common zone of private residential activity.
Appellant urges that, even if his crop was therefore in an open field, the officers’ simultaneous scrutiny of his house and curtilage was an invalid warrantless search. That impropriety, appellant asserts, requires suppression of the marijuana discovery. For several reasons, we cannot accept this premise.
The surveying officers admitted that they did not avert their eyes from the terrain surrounding the suspicious cultivation, and the aerial photos presented to the magistrate depict not only the garden itself, but the nearby trailers, hillsides, trails, and roads. One officer conceded he unavoidably
It is clear, however, that the focus of the examination for criminal activity was the cultivated area outside the curtilage. The officers saw nothing criminal within the curtilage, and it appears that their primary interest in noticing this area was to establish its relationship, if any, to the outlying crops. The observations took place from over 1,000 feet above defendant‘s property. The officers testified that the photographs presented to the magistrate, though some may have been taken with telephoto equipment, accurately show the scale of objects as they appeared to the naked eye.6 If that is so, the details of human activity could scarcely have been discernible from the aircraft. All the photographs reveal is evidence that inhabited structurеs exist in the vicinity, and that they may be related to cultivation in open fields. The most casual passing airplane could see as much.
We think that observation of crops growing in open fields is not transformed into an unconstitutional search when the officers incidentally and unavoidably observe the existence of a nearby home and curtilage, and its relationship to the fields, from a visual altitude at which the possibility of intrusion on private activities below is remote.7
Our holding here is distinguishable from that of Cook, supra. There we prohibited all warrantless aerial scrutiny of a residential curtilage for the particular purpose of confirming a suspicion that criminal activity is taking place there. There is a difference, significant for constitutional purposes, between surveillance focused on a particular residential yard, on
Finally, we cannot ignore the differing law enforcement interests involved. The inquiry whether particular privacy expectations are “reasonable,” and whether government has intruded upon them “unreasonably,” involves a weighing of the competing privacy and law enforcement interests. (See, e.g., New Jersey v. T.L.O. (1985) 469 U.S. 325, 336 [83 L.Ed.2d 720, 731, 105 S.Ct. 733] and conc. opn. of Blackmun, J., at 469 U.S. at p. 351 [83 L.Ed.2d at p. 741]; United States v. Martinez-Fuerte (1976) 428 U.S. 543, 560-567 [49 L.Ed.2d 1116, 1129-1134, 96 S.Ct. 3074]; United States v. Brignoni-Ponce (1974) 422 U.S. 873, 883-884 [45 L.Ed.2d 607, 617-618, 95 S.Ct. 2574]; Terry v. Ohio (1968) 392 U.S. 1, 21 [20 L.Ed.2d 889, 905-906, 88 S.Ct. 1868]; People v. Scott (1978) 21 Cal.3d 284, 292-293 [145 Cal.Rptr. 876, 578 P.2d 123].)
The People advise, and appellant does not dispute, that Humboldt County‘s random surveillance program was prompted by the rise of a large-scale illegal marijuana cultivation industry in remote areas of the county. There have been serious consequences, the People suggest, for the safety of law-abiding residents and visitors. Precisely in order to avoid discovery, the growers have retreated to places where detection from the ground is difficult or impossible. Persons who do approach a cultivated plot face the prospect of armed resistance. (See fn. 2, ante.) Secure in their weapon-enforced privacy, the farmers pursue their illicit trade unhindered.
Aerial surveillance of these remote, inaccessible, and dangerous areas may be the only feasible means of confronting this extraordinary law enforcement problem. Aerial surveillance also seems the least intrusive way of doing so, since it does not physically impinge at close range upon persons or private premises. (See discussion, ante.)
In our view, mere suspicion that marijuana is growing in thе enclosed backyard of a single residence can never justify a warrantless aerial invasion of the enclosure. On the other hand, we do not believe that airborne police officers infringe “unreasonably” on legitimate privacy in homes and curtilages by merely observing the configuration of nearby structures while patrolling open fields for large-scale marijuana cultivation. We conclude
In so holding on these facts, we do not minimize the difficulties involved in keeping a random surveillance program of this kind within proper bounds. At the behest of irate citizens, a United States District Court has already enjoined certain overreaching surveillance practices of the Humboldt County program. (Nat. Org. for Reform of Marijuana Laws v. Mullen (N.D.Cal. 1985) 608 F.Supp. 945.) In the wake of Proposition 8, such civil actions may prove the most effective bulwark against violations of the state Constitution by agents of law enforcement.9 A principal advantage of this form of enforcement is that all parties will have a full opportunity to present facts bearing on the constitutional reasonableness of a particular surveillance program.
Perhaps the most significant protection for the privacy interest of innocent citizens would be the development of regulatory standards which prescribe and limit the manner in which overflights may be conducted. Such standards would have multiple advantages: they would, among other things, provide law enforcement personnel with a clear guide to the exercise of their discretion; serve as a basis for internal discipline in the event of violation; and
2. Aerial identification of marijuana plants.
Appellant urges that probable cause for issuance of the warrant was not established, since it is impossible to identify marijuana plants from altitudes of 1,000 feet and above. Both Agеnt Brown, who was the warrant affiant, and Detective Vulich testified that their opinions arose from the evidence of cultivation—that the suspected plants were lusher green than the surrounding vegetation, spaced evenly and established in orderly rows in an area of “disturbed” earth. Moreover, the officers noted, the plants were within an enclosed area some distance from the structures on the property and connected to the structures by footpaths. Both officers admitted they could not distinguish the individual shapes or characteristics of the plants.
At the preliminary hearing, a botanist, Dr. Norris, testified that marijuana has no unique color which distinguishes it from other cultivated crops.10 It is impossible, said Dr. Norris, to determine from 1,000 feet the identity of common plants under cultivation.
3. Probable cause to search multiple dwellings.
The warrant affidavit executed by Agent Brown described appellant‘s property as including a “structure” with a “light colored roof” and another nearby “structure . . ., possibly a mobil [sic] trailer.” It indicated that paths ran from each structure to the gardens, leading Brown to believe that the “occupant(s)” controlled the cultivated areas. The affidavit sought permission to search both structures because, in Brown‘s experience, commercial marijuana growers typically use “their houses and other outbuildings” to dry, cure, store, and hide their crops. The warrant issued on that basis.
When the warrant was executed, both structures turned out to be trailers used as residences. Both were searched; in the larger, used by appellant and his wife, marijuana and documents were found. Appellant argues that the warrant was fatally defective because the affidavit failed to establish independent probable cause for the search of multiple dwellings.
We cannot agree. In the first place, contrary to appellant‘s assertion, there is no indication that Agent Brown negligently or intentionally omitted the
Moreover, any omission in that regard neither undermined probable cause nor made the warrant affidavit “materially misleading.” (Kurland, supra, 28 Cal.3d at p. 385.) There was ample information from which the magistrate could reasonably conclude that both structures were connected to the cultivation activities on the parcel, and that both were likely to contain criminal evidence. (Compare People v. Joubert, supra, 118 Cal.App.3d 637, 649-650 [affidavit described “dwelling places and/or outbuildings” on a 28-acre parcel but stated affiant‘s opinion only that “the dwelling house” contained criminal evidence]; People v. Sheehan (1972) 28 Cal.App.3d 21, 24-26 [103 Cal.Rptr. 201] [warrant to search “all structures, tents, lean-tos, and campsites” on 315-acre communal ranch, based on discovery of marijuana patch not near any dwelling].)
The judgment is affirmed.
Mosk, J., and Reynoso, J., concurred.
Broussard, J., concurred in the judgment.
LUCAS, J.—I concur in the judgment. As I explained in my dissenting opinion in People v. Cook (1985) 41 Cal.3d 373, 386 [221 Cal.Rptr. 499, 710 P.2d 299], aerial surveillance conducted at a reasonable height and in a nonintrusive manner cannot be deemed an “unreasonable” search under the California Constitution. That analysis would apply whether the officers surveyed a backyard and “curtilage,” as in Cook, or mere “open fields,” as here. Police surveillance which is limited to detecting growing marijuana plants simply cannot be deemed “unreasonable” conduct.
As the majority observes, it is unquestionable that the federal Constitution would not invalidate a warrantless aeriаl search, whether of open fields (see United States v. Oliver (1984) 466 U.S. 170, 176-184 [80 L.Ed.2d 214, 222-228, 104 S.Ct. 1735]), or of an enclosed backyard (California v. Ciraolo (1986) 476 U.S. 207 [90 L.Ed.2d 210, 106 S.Ct. 1809]). I would reach the same result under the state Constitution. Indeed, were this case governed by Proposition 8, which added
BIRD, C. J., Dissenting. — Today a majority of this court sanction an unparalleled program of indiscriminate aerial surveillance of the property, homes and persons of innocent citizens by the government. The opinion rejects appellant‘s challenge by concluding that the government‘s warrantless examination of his home and curtilage in the course of its random surveillance did not infringe upon any legitimate expectation of privacy. I do not agree.
The majority‘s holding is remarkable given our recent opinion in People v. Cook (1985) 41 Cal.3d 373 [221 Cal.Rptr. 499, 710 P.2d 299]. There, this court held that the aerial surveillance of defendant‘s curtilage was an unconstitutional search under
This case aptly illustrates the dangers inherent in analyzing privacy interests according to the discredited “protected areas” approach. By focusing on what they consider to be the “diminished privacy” expectations in the area where the marijuana was discovered, the majority lose sight of the scope of the invasive conduct. In addition to their faulty analysis, the majority reach their result by drastically misreading the record or ignoring it completely. Let me explain.
The record reflects that a police aircraft was making a random search for marijuana under cultivation. The officers had no reason to believe that they would find such cultivation on appellant‘s property or on any other specific property. The Attorney General does not dispute that appellant‘s home, surrounding land and a nearby structure were examined and photographed when the property fortuitously came within the sights of the airborne officers. He also does not dispute that these areas were hidden from public view.
It is well settled that a warrantless ground search of appellant‘s curtilage would have been per se unreasonable. (See Lorenzana v. Superior Court (1973) 9 Cal.3d 626, 634 [108 Cal.Rptr. 585, 511 P.2d 33]; People v. Edwards (1969) 71 Cal.2d 1096 [80 Cal.Rptr. 633, 458 P.2d 713].) The Attorney General, however, asserts an unlimited right to examine residential property from the air. He claims this surveillance may be conducted randomly, even though such a program of surveillance would necessarily intrude upon the property of innocent persons.
The Attorney General raises two arguments to support his claims. He argues that appellant‘s curtilage was in plain view of the airborne officers and that the prevalence of air traffic precluded a reasonable expectation of privacy from aerial surveillance. These same arguments were advanced in Cook and were firmly rejected. (See Cook, supra, 41 Cal.3d at pp. 380-385.)
The Attorney General raises an additional argument which was not applicable in Cook. He maintains that expectations of privacy are not reasonable in open fields. Since the marijuana gardens were located in an open field, the examination of appellant‘s curtilage was of no significance. According to him, privacy interests “are not resurrected in a field by the otherwise irrelevant observation of some other place, such as a rooftop or backyard.” (Original italics.) The majority adopt this reasoning and uphold the surveillance of appellant‘s property.
According to the majority opinion, this activity by the police did not infringe upon Mr. Mayoff‘s privacy interests in the lands surrounding his home since, although one agent “unavoidably examined the apparently inhabited zone,” the “focus of the examination for criminal activity was the cultivated area outside the curtilage.” (Maj. opn., ante, at p. 1316.)1 The majority‘s conclusion presumes (1) that the officers only inadvertently or incidentally looked into a curtilage and (2) that no warrant is required
The majority‘s first premise totally ignores the fact that the officers participating in the surveillance of the property acknowledged that they examined the curtilage for evidence of criminal activity. The majority also disregard the prosecution witnesses’ extensive testimony which established that a detailed inspection of residences and their surrounding areas was an essential element of the aerial identification of marijuana. Further, the majority discount the significance of the evidence showing that an intrusion upon the curtilage commonly occurs in the course of the current program of indiscriminate aerial surveillance.
The majority‘s second premise misses the point as to the fundamental principles of search and seizure analysis. One need only look to People v. Cook, supra, 41 Cal.3d 373, to find the correct analytical framework. There, our court stated: “Determining the legality of warrantless police forays into allegedly private zones оf activity was once almost exclusively a matter of ascertaining the scope of the property interests of the individual whose privacy was purportedly invaded. [Citations.] However, in 1967, Katz v. United States [1967] 389 U.S. 347, affirmed that constitutional limitations on police searches and seizures protect ‘people, not places.’ (P. 351.) [
“Though location is no longer the sine qua non of search-and-seizure analysis, it remains relevant under the Katz test. The privacy one is entitled to expect in a particular place is governed primarily by common habits in the use of such property. [Citations.] [¶] Thus, we guard with particular zeal an individual‘s right to carry on private activities within the interior of a home or office, free from unreasonable governmental intrusion. [Citations.]” (Cook, supra, 41 Cal.3d at pp. 378-379.)
In this case, it is the traditional sanction of the outdoor area adjacent to the home — rather than the home itself — which the majority plaсe at risk. In Cook, this court recognized the “high privacy interest in the ‘curtilage’ of a residence . . . .” (Id., at p. 379.) Cook also noted the recent holding of the United States Supreme Court that the curtilage “‘has been considered part of [the] home itself for
Even before Oliver, lower federal courts had viewed the home and curtilage as equivalent for purposes of
Appellant‘s 40-acre parcel is located in rural Humboldt County. The prosecutor indicated that the “area [was] once [a] sheep or cattle ranch and is now being subdivided into forty-acre plots . . . for residential purposes.” The property contains 2 residences located 40 to 50 feet apart. The marijuana gardens were approximately 200 feet from the nearest dwelling. Another residence surrounded by several outbuildings is located on a neighboring parcel a relatively short distance from appellant‘s residences. This second residence is clearly visible in the aerial photographs taken during the overflight.
Despite the majority‘s suggestions to the contrary, the record reveals that the aerial inspection of appellant‘s home and surrounding area was quite detailed. On July 23, 1980, Agent Brown, Detective Vulich and a pilot flew south from Eureka toward Garberville looking for marijuana cultivation. According to Agent Brown, when the plane “just happened to fly over [the Mayoff property],” the officers began examining the ground for “indicators” of illegal cultivation. Detective Vulich testified that he observed the two residences on defendant‘s property, noting that they appeared to be “inhabited structures.” He also observed that one was a larger mobilehome with a light-colored roof and he estimated its square footage. Further, he examined the paths leading from the residences to the suspect gardens to see if there might be any possible indication of marijuana cultivation.
Agent Brown examined the two residences on the property. One of the residences was a mobilehome with a wooden addition built on and the other was a smaller trailer located just down the road. The first indication of possible marijuana cultivation were “the paths leading . . . from the residence to the garden sites. . . .” He observed that the gardens were planted
On August 4, 1980, Detective Vulich returned to the skies over appellant‘s property, again without a warrant. During this second surveillance, he took numerous photographs, not only of the suspected marijuana gardens but also of appellant‘s residences and their adjacent lands. Vulich photographed the neighboring farmhouse and its curtilage with an 80-200-millimeter telephoto lens.2
The record also makes clear that scrutiny of the curtilage is essential to the aerial identification of marijuana even when the suspect garden technically lies outside of the curtilage. The two officers participating in the surveillance of appellant‘s property had been trained in aerial marijuana identification and had a combined total of almost 20 years in making such identifications. Both officers admitted that from the altitudes maintained marijuana plants could not be distinguished from other plants which might be found in a typical vegetable garden.
The officers were able to form an opinion about the nature of the plants only by reference to external “indicators.” Three of the four primary indicators the officers were trained to look for require an inspection of the curtilage. In addition to “row-like” planting and/or the color of the garden, the proximity of the residence to the garden, the presence of pathways leading from the residence to the garden and the presence of water storage were taken into account. Thus, contrary to the majority‘s suggestion, it appears that an intensive inspection of the curtilage was a prerequisite for establishing probable cause to validate the later ground search.
A fundamental problem with the majority‘s analysis is that it assumes that the “principal focus” of the surveillance in this case was confined to open fields. (Maj. opn., ante, at p. 1308.) The state has never suggested
It is clear from the aerial surveillance cases before us that the majority‘s characterization of the surveillance program does not comport with reality. This court recently granted review in several cases involving aerial surveillance. The most distant gardens in these cases were found 200 to 300 feet from the residence. (People v. Kramer (Cal.App.) hg. granted Mar. 22, 1984 (Crim. 23607); People v. Agee (Cal.App.) hg. granted May 24, 1984 (Crim. 23738).) In another case, a few marijuana plants were found in vegetable gardens within 20 feet of the home, and more were found next to a swimming pool and greenhouse — clearly within the immediate curtilage. (People v. Liondakis (Cal.App.) hg. granted May 31, 1984 (Crim. 23752).) In still another case, the officers spotted a few marijuana plants in a small roofless greenhouse located next to the residence in an enclosed backyard (People v. Fitzgerald (Cal.App.) hg. granted May 24, 1984 (Crim. 23736).) In all but one of these cases, the gardens appear to have been relatively small in scale.
It is apparent, then, that the focus of the officers’ attention was wherever they happened to spot areas of lush green vegetation which might be indicative of marijuana cultivation. In this case, that location happened to be an area 200 feet from the nearest sign of human habitation. In other cases, the suspicious vegetation — and therefore, the focus of police attention — was as near as 20 feet from an apparently inhabited dwelling or in an enclosed backyard. There is absolutely no evidence to support the majority‘s assertion that the focus of police surveillance excluded curtilage areas.
Further, the majority completely ignore the extensive testimony regarding the nature of the aerial surveillance program operated in Humboldt County. The program is conducted from June through November of each year. The flyover program covers virtually the entire county outside of the municipal areas of Eureka, Arcata and Fortuna.4 The officers “terrace” or survey an area by flying in a zigzag fashion, “looking constantly” at the ground. The
When the officers “see something that [they] think may be suspicious” they begin circling to inspect the area in greater detail and sometimes fly at a lower altitude. During this process, they examinе nearby residences and the areas surrounding them. From the air, they are able to observe people and vegetable gardens planted “fairly close” to homes. The officers also examined residences and curtilages from the air even when they observed no marijuana gardens in the vicinity. None of the officers indicated that they made any attempt to avoid examining homes or adjacent yards.
Despite substantial evidence indicating the general intrusiveness of the program the officers’ admission that they conducted a purposeful examination of appellant‘s curtilage, the majority conclude that the random surveillance did not constitute a search under either the federal or state Constitutions. I strongly disagree. The aerial surveillance of appellant‘s property clearly violated our state Constitution.
The police had no prior information regarding marijuana cultivation on any property. They were flying over and indiscriminately examining the ground for marijuana gardens. When appellant‘s property came within sight, the officers surveyed that area. Flying at 1,000 feet, they examined appellant‘s curtilage and fields for evidence. The police returned to the property on a second occasion, again flying at 1,000 feet, and extensively photographed the residences and the curtilages.
The majority conclude that the police conduct did not implicate аppellant‘s privacy interests. The majority distinguish Cook, supra, 41 Cal.3d 373 by the fact that here, the marijuana garden was found outside the curtilage (see maj. opn., ante, at pp. 1307, 1316; but see ante, fn. 1), while the marijuana garden in Cook was observed inside the curtilage. (Cook, supra, 41 Cal.3d at p. 378.) The majority‘s theory is that “the open fields doctrine provide[d] an initial justification for the officers’ airborne presence.” (Maj. opn., ante, at p. 1317.) Because the police investigation “focused” on an area 200 feet from the residence and “merely notice[d]” the relationship of dwellings to the focused area, the surveillance was not objectionable. (Id., at p. 1317.) The majority indicate, however, that scrutiny of the curtilage “for the particular purpose of confirming a suspicion that criminal activity is taking place there,” remains unconstitutional. (Id., at p. 1316.)5
It cannot be disputed that the officers’ inspection of appellant‘s curtilage was at least as intrusive as the inspection in Cook, supra, 41 Cal.3d 373. The infringement of appellant‘s “high privacy interest” in his curtilage was no less invasive even if one were to assume that the purpose of this inspection was only to confirm a suspicion of marijuana cultivation in a field. However, the majority overlook this simple truth by once again examining the issue through a “zones-of-privacy” approach. Under the majority‘s reasoning, protection from government intrusion depends not on the extent to which legitimate privacy expectations are infringed, but on the zone in which the contraband is discovered. If found in a zone of “diminished privacy,” then the intrusion upon other zones becomes, to use the Attorney General‘s term, “irrelevant.”6
In Cook, this court recognized that the concept of protected zones has little meaning when it comes to aerial surveillance. “Purposeful surveillance from the air simply lays open everything and everyone below — whether marijuana plants, nude sunbathers, or family members relaxing in their lawn chairs — to minute inspection. The usual steps one might take to protect his privacy are useless.” (People v. Cook, supra, 41 Cal.3d at p. 382.)
The majority‘s unprecedented conclusion, that random aerial searches can be “focused” to detect illegal crop cultivation without infringing upon “innocent activities occurring within a legitimate zone of protected privacy” (maj. opn., ante, p. 1317), flatly ignores the reality of indiscriminate surveillance. At the same time the majority urge the aerial police to avoid scrutiny of the curtilage, they restrict their flights to altitudes from which the officers admit they are unable to identify marijuana cultivation without reference to the curtilage.
Today‘s ruling all but abolishes the constitutional protection recognized in Cook for residents of rural and semirural counties. In its place, these residents are left with the illusory protection of a requirement that law enforcement officials “focus” their attention on open fields during random overflights of the residents’ homes and yards. Nothing in the majority opinion prohibits plain view observations of activities within curtilage areas, so long as the observer‘s attention is “focused” on a nearby open field.
As one commentator observed, the right to be free from unreasonable searches “protects not against incrimination, but against invasions of privacy — or rather . . . of the right to maintain privacy without giving up too much freedom as the cost of privacy. The question is not whether you or I must draw the blinds before we commit a crime. It is whether you and I must discipline ourselves to draw the blinds every time we enter a room, under pain of surveillance if we do not.” (Amsterdam, Perspectives on the Fourth Amendment (1974) 58 Minn.L.Rev. 349, 403 [hereinafter Fourth Amendment].)
The constant threat of surveillance during random overflights will require individuals “to erect opaque cocoons within which to carry on any affairs they wish to conduct in private, and the concomitant chill such a requirement [will] place on lawful outdoor activity, [is] inimical to the vision of legitimate privacy which underlies our state Constitution.” (See Cook, supra, 41 Cal.3d at p. 377.)7
Random surveillance is nothing more than an exploratory search, i.e., an effort to discover evidence of criminal activity undertaken without a warrant, probable cause or even particularized suspicion. Such searches are viewed with profound disfavor precisely because they threaten the security of the law-abiding as well as the lawbreaker, chilling the legitimate activities of the innocent as well as the illicit schemes of the guilty. (See, e.g., People
Nevertheless, the majority claim such invasions of personal privacy are necessary to advance the significant law enforcement objectives at stake. I cannot agree. It is possible to serve the legitimate governmental purposes of the surveillance program without sacrificing the privacy rights of our citizens who live in areas where there will be indiscriminate police surveillance.
Many of the counties subject to random aerial surveillance programs contain vast areas of public lands. The Attorney General asserts that a substantial proportion of the marijuana cultivation occurs on such lands. Also, there is evidence that marijuana growers are increasingly reacting to the aerial surveillance programs by moving their operations to public lands in order to avoid detection. The impact of marijuana cultivation on the users of public lands, such as “hikers, campers, fishermen, and hunters,” is a significant governmental objective of the surveillance program cited by the majority. (Ante, p. 1308, fn. 2.) The majority state that the transformation of rural areas “formerly open to recreational use into illegal armed camps
A program of random aerial surveillance could be operated in conformity with constitutional principles if restricted to publicly owned lands where there generally would be no infringement upon the elevated privacy rights of any residences or any curtilage areas surrounding residences. Aerial surveillance of specific privately owned fields could be permitted to confirm reports of marijuana cultivation. In view of the unique problems identified by the Attorney General, this latter surveillance might be allowed on the basis of a reasonable аnd particularized suspicion. A program restricting indiscriminate surveillance to public lands and allowing site-specific searches of private fields on less than probable cause, would permit law enforcement agencies to survey a substantial portion of the area of suspected cultivation and would also serve to combat any danger to recreational users of the land. Such a program would at the same time protect the legitimate privacy rights of our innocent citizens living in our rural counties.
The inquiry in any search and seizure case should be “whether, if the particular form of surveillance practiced by the police is permitted to go unregulated by constitutional restraints, the amount of privacy and freedom remaining to citizens would be diminished to a compass inconsistent with the aims of a free and open society.” (Fourth Amendment, supra, 58 Minn.L.Rev. at p. 403.) The procedures at issue here “too closely resemble[] the process of the police state, too dangerously intrude[] upon the individual‘s reasonable expectancy of privacy, and thus too clearly transgress[] constitutional principle” to be left substantially unregulated. (Lorenzana v. Superior Court, supra, 9 Cal.3d at p. 629.)
By permitting indiscriminate aerial surveillance, the majority effectively limit the traditional sanctity of residential property to the area enclosed by the four walls of the dwelling house. Such a holding is inconsistent with those principles which separate оur open and democratic society from societies in which the government may spy on its citizenry unfettered by the rule of law.
Respondent‘s petition for a rehearing was denied January 29, 1987.
Notes
Nor do we accept defendant‘s suggestion that use of a camera is impermissible, since it allows scrutiny of the photographed area “at leisure.” For federal purposes, the United States Supreme Court has recently concluded that an optical device which “enhanced somewhat” the details visible to the naked eye from a passing aircraft did not raise constitutional concerns. (Dow Chemical, supra, 476 U.S. 227.) The photos here, taken with a garden-variety 35 millimeter camera, show no potential for useful enhancement or magnification. the property was located in a rural area (maj. opn., ante, at p. 1309); in Cook it was located in a semi-rural area (41 Cal.3d at p. 377). Here, they note, the plane flew over the property on only two occasions (maj. opn., ante, at p. 1309); in Cook only one overflight occurred (41 Cal.3d at p. 377). Finally, here, the plane maintained an altitude of over 1,000 feet during each flight (maj. opn., ante, at p. 1316); in Cook the plane maintаined an altitude of at least 1,600 feet (41 Cal.3d at p. 377). Presumably the majority would have upheld the surveillance in Cook had the officers discovered during the overflight that the marijuana was actually growing not in Mr. Cook‘s yard, but in an adjacent field. Under the majority‘s analysis, even though the intrusiveness of the surveillance would have been the same, the location of the discovery would have rendered the overflight constitutional.
The suggestion is appealing at first glance. The warrant clause is the Constitution‘s most important safeguard against overzealous government intrusions on legitimate privacy. Nonetheless, a majority of this court have concluded that the proposal must be rejected. It would impose upon law enforcement agencies a cumbersome two-step procedure, with one warrant necessary to permit the initial aerial surveillance, then, in most cases, another to authorize any subsequent ground search. Moreover, we find it difficult to conceive what advance information the officers could provide that would assist the magistrate, except in the most extreme cases, to evaluate the probable merit of a particular proposed overflight. Nor is a magistrate in a position to prejudge the infinite variations in altitude, distance, flight pattern, and air speed which might arise from conditions faced by the aircraft‘s pilot. The searches conducted in colonial America under the general warrants and the writs of assistance are regarded as “one of the primary causes of the American Revolution” and the inspiration for the constitutional prohibition against unreasonable searches and seizures. (Schaefer, Aerial Surveillance and the Fourth Amendment (1984) 17 J. Mar. L.Rev. 455, 460; see also Fourth Amendment, supra, 58 Minn.L.Rev. at pp. 363, 366.) “[T]he primary abuse thought to characterize the general warrants and the writs of assistance was their indiscriminate quality, the license that they gave to search Everyman without particularized cause . . . .” (Fourth Amendment, supra, 58 Minn.L.Rev. at p. 366.) “‘[W]arrants lacking strict particularity as to location to be sеarched or articles to be seized were deemed obnoxious’ because of the root principle stated by Lord Mansfield: that ‘[i]t is not fit, that the receiving or judging of the information should be left to the discretion of the officer. The magistrate ought to judge; and should give certain directions to the officer.’ The power asserted by the English messengers and colonial customs officers and condemned by history was ‘a discretionary power . . . to search wherever their suspicions may chance to fall,’ ‘a power that places the liberty of every man in the hands of every petty officer.‘” (Id., at p. 396, fns. omitted.) Today, the sound of English messengers at the doorstep has been replaced by the drone of the police surveillance plane. As with the general warrants, a dangerous consequence of indiscriminate aerial surveillance is the intrusion on the privacy of citizens without particularized cause. As the testimony in this case proves, the surveillance officers examine an area in detail whenever their glances fall on “something [they] think may be suspicious.” The officers have unfettered discretion to decide whose privacy will be invaded. These parallels to colonial times are especially significant since these very characteristics of the general warrants and writs of assistance led to the enactment of the Fourth Amendment and in no small measure inspired the creation of this democratic society.
