Statement of the Case
On May 16, 1978, a complaint was filed in the Mariposa Justice Court charging petitioners Skeet Dewayne Phelan and Carol Jean Phelan with cultivating marijuana in violation of Health and Safety Code section 11358. Petitioners pled not guilty and at the preliminary hearing moved to suppress the evidence of marijuana seized on their premises (Pen. Code, § 1538.5). The motion was denied. Petitioners renewed their motion to suppress in the superior court, and after a special hearing at which the transcript of the preliminary hearing was received in evidence along with oral testimony of witnesses, the motion again was denied.
*1008 Petitioners filed with this court a petition for writ of mandate. We stayed further proceedings of the action and issued an order to show cause why the writ should not be granted.
Statement of the Facts
Around May 1, 1978, Officer Wackerman of the Mariposa County Sherifif’s Department received information from California Highway Patrol Officer Roger Matlock that he had received a report from an informant that a marijuana garden was located in a small ravine on the west side of the property located “straight across the road from Elliott’s Corner and Chowchilla Mountain Road” in a rural area of Mariposa County. The informant had stated that the property had a new road leading into it. Wackerman went to the hall of records and obtained assessor parcel maps of the area and determined that the property on which the marijuana garden supposedly was located belonged to petitioners. The officer also determined that the property located to the west of petitioners’ property belonged to Mr. Perkins. Since the parcel maps did not contain the dimensions of the property, Wackerman went back to the hall of records and obtained information concerning the acreage of the respective properties.
On May 8, 1978, Sergeant Richards of the sheriff’s department also contacted Mr. Perkins and verified that his property bordered petitioners’ property to the east. Richards asked Perkins for written permission to enter his property, explaining that he could not tell Perkins the true purpose of the investigation but would explain later. Perkins consented to the officers entering his property.
Later on May 8, Officer Wackerman and another officer went onto the Perkins’ property for the purpose of engaging in a surveillance of petitioners’ property to locate the marijuana garden. The officers walked to an area which they believed to be near the east property line of Perkins’ property. They testified they spent several hours looking for the marijuana garden and also attempting to establish the precise location of the line separating petitioners’ and Perkins’ property. They were unable to find a corner or line marker but estimated the boundary location based on the assessor’s map and Officer Wackerman’s general familiarity with the land in that area. The officers finally observed what they suspected to be the marijuana garden from a vantage point atop a rocky knoll on the side of a hill above the narrow ravine in which the garden was located. The ravine and garden were to the east from where they stood and about *1009 125 feet distant. The terrain was rocky, shrub-covered and difficult to traverse. There were no footpaths or roads in the area. The place on the hill where the officers stood was covered with large rocks and boulders.
The garden appeared to the officers to be bounded on the east side and on a part of the west side by a four-foot high chicken wire fence laced with branches from live oak trees and heavy shrubbery; large rocks made a natural barrier on the north and there was a wire gate through the trees on the south. Trees and brush also formed a natural barrier about the garden. Officer Wackerman testified that from the appearance of the enclosure, whoever had developed the garden intended that it be concealed from view. The garden was “pretty much” totally enclosed. The officers were able to see the marijuana plants through an opening in the trees and brush from their vantage point on the hill. Although the officers suspected the plants were marijuana when they first observed the garden, they were able to verify their suspicions only by examining the plants with the aid of binoculars. Subsequent investigation showed there were approximately 290 plants growing in the garden, from small plants one inch in height to full grown plants three feet in height.
The officers also observed a camp-type trailer some distance from the garden. The officers concealed themselves behind large rocks on the side of the mountain and observed two people—later identified as petitioners —walk into and tend the garden. It appeared to the officers that the people probably resided in the camp trailer. On May 9th the officers returned and continued their surveillance from their hiding place on the hillside for about two and one-half hours but saw no activity. On May 10th the officers returned to their hiding place where they again saw petitioners tending their garden. The officers made a video tape for positive identification. Subsequently, petitioners were arrested for cultivation of marijuana.
The officers testified that when they first observed the marijuana garden from the rocky knoll on the side of the hill they believed they were still on Mr. Perkins’ property; however, it was later determined that they had trespassed 30 to 80 feet onto petitioners’ property. 1
*1010 Discussion
It has been said that when observations are made by an officer from a location to which he has not been invited the intrusion is an unlawful search unless made pursuant to a warrant
(Lorenzana
v.
Superior Court
(1973)
Flistorically, the Fourth Amendment was held applicable only to lands within the curtilage, i.e., the enclosed or fenced land about the house. In
Hester
v.
United States
(1924)
In
Edwards, supra,
the court articulated the test for determining whether a warrantless search of open fields violates the Fourth Amendment: “[A] number of cases involving claims of unconstitutional searches or seizures in open fields . . . have stated their conclusions in terms of whether the place was a ‘constitiitionally protected area.’ That phrase, however, does not serve as a solution in all cases involving such claims, and we believe that an appropriate test is whether the person has exhibited a reasonable expectation of privacy, and, if so, whether that expectation has been violated by unreasonable governmental intrusion.”
(People
v.
Edwards, supra,
In the present case, petitioners clearly entertained a subjective expectation of privacy in the cultivation of their marijuana garden. Furthermore, under all of the circumstances it must be concluded that their expectation of privacy was objectively reasonable. The garden was located in an isolated narrow ravine on petitioners’ foothill property which they apparently used as a residence, at least part of the time. The garden was protected by trees and a four-foot wire fence covered with brush and branches from oak trees. The officers acknowledged that the person who maintained the garden had intended to conceal it from view. There were no footpaths, roads or other indicia of common or public ownership or use in the immediate area where the officers located themselves (cf.
Dean
v.
Superior Court, supra,
The fact that some of the marijuana plants were visible through an opening in the barrier about the garden from a vantage point on the hill
*1012
above the ravine does not negate petitioners’ reasonable expectation of privacy. Absent adjacent trails, roadways or other common areas inviting access to the hill, a reasonable man would not anticipate the presence of uninvited persons at that location (cf.
People
v.
Bradley
(1969)
Nor does the absence of boundary fences or “no trespass” signs of itself negate petitioners’ objective expectations of privacy. If petitioners had not attempted to conceal their garden by enclosing it with a fence and shrubbery in addition to the natural trees and rocks in the ravine, they might be deemed to have anticipated the presence of trespassers who would spot the plants and recognize them as marijuana. In this situation, petitioners’ “internal, uncommunicated need for privacy” arising from their criminal activity would not qualify for Fourth Amendment protection
(Dean
v.
Superior Court, supra,
Even if it be assumed that petitioners should have anticipated the presence of occasional trespassers such as cattlemen, hunters and hikers on their unfenced land, there is no basis for holding that they should have anticipated the presence of police officers engaged in an exploratory search for marijuana. The concept of a
particularized
objective right to privacy has been recognized in many cases. For example, in
People
v.
Sneed, supra,
Several cases illustrate the proper analysis in determining whether the defendant had exhibited a reasonable expectation of privacy. In
People
v.
Little, supra,
In
Dean
v.
Superior Court, supra,
In
People
v.
Sneed, supra,
Having determined that petitioners had a reasonable expectation of privacy as to their marijuana garden, we must decide whether their expectation of privacy was violated by an unreasonable police intrusion. In
Lorenzana
v.
Superior Court, supra, 9
Cal.3d 626, the Supreme Court seems to equate unreasonableness with
any
police intrusion into a citizen’s right of privacy. It says, “We now recognize the constitutional encasement which renders
inviolable
the individual’s reasonable expectation of privacy; any governmental intrusion into that privacy is an ‘unreasonable search’ within the meaning of the Fourth Amendment, whether that intrusion be the traditional physical search [citation] or a surreptitious auditory invasion [citations] or indeed visual intrusion [citations].” (Italics added,
In seeking a decision that the officers reasonably intruded into petitioners’ privacy, the People ask us to carve out another exception to the warrant requirement on the basis of the officers’ mistaken but good faith belief that they were on Mr. Perkins’ property when they discovered the marijuana garden. The People seek to support their argument by the cases which hold that a search is not unreasonable if made with the consent of a third party whom the police reasonably and in good faith believe has authority to consent to their search
(People
v.
Gorg
(1955)
The People also argue that where officers in good faith try to stay off the defendants’ property in conducting their surveillance, a mere inadvertent trespass should not invalidate an otherwise lawful activity, particularly when the surveillance is conducted in open areas where boundary lines are difficult to locate. We reject such a simplistic approach. As we have explained, the inquiry is not whether the officers have violated a particular boundary line in their searching but whether they have invaded the reasonable expectation of privacy exhibited by defendants.
The expectation ofprivacy defines the parameters of the right to search.
Thus, while the possessor of unfenced rural property should anticipate the presence of occasional trespassers, the lack of boundary fences alone does not foreclose a reasonable expectation of privacy as to a particular area on the land such as the ravine and enclosed garden in the present case. We perceive no difference between fenced land on the one hand and open land having a particular enclosed area on the other hand, insofar as the Fourth Amendment is concerned.
(People
v.
Edwards,
*1017
supra,
In sum, considering the totality of the circumstances, we conclude that the officers unreasonably invaded petitioners’ reasonable expectation of privacy as to their garden. The officers were not presented with an emergency or exigent circumstances that would have justified their acting without a warrant, nor do the facts bring the case within any of the well-delineated limited exceptions to the warrant requirement. By electing to engage in a surreptitious surveillance from the adjoining owner’s property rather than seeking a search warrant, the officers assumed the risk of intruding into petitioners’ constitutionally protected area of privacy. Having done so, the search was illegal regardless of the officers’ good faith.
It is ordered that a writ of mandamus issue directing the respondent court to suppress the marijuana evidence.
Brown (G. A.), P. J., and Hopper, J., concurred.
The petition of the real party in interest for a hearing by the Supreme Court was denied May 24, 1979. Clark, J., was of the opinion that the petition should be granted.
Notes
Although we will assume for the purpose of this opinion that the officers believed in good faith they were on Perkins’ property, it is questionable whether their subjective belief was objectively reasonable. They testified that they had found a wire gate unattached to a fence at the bottom of the ravine so they stayed west of the ravine believing it to be on Perkins’ property. However, the officers had already concluded from the information they had originally received from Officer Matlock, together with the assessor maps, that the ravine was located on petitioners’ property. The maps also showed *1010 “a finger of a small hilltop” as being on petitioners’ property. Furthermore, the officers failed to ask Mr. Perkins to show them the precise location of the property line. Officer Wackerman acknowledged that if Mr. Perkins had been told the true purpose of the visit to his property, he probably would have consented to the officers’ use of his property. Thus, at the very least it can be argued that the officers were negligent in believing they were still on Mr. Perkins’ property when they observed the marijuana.
Respondent contends that petitioners’ garden was visible from Perkins’ property. The contention is based on Sergeant Richards’ testimony at the superior court suppression hearing that after the preliminary hearing the officers returned to Perkins’ property to fix the exact location of his east boundary line and found “one spot” on a hillside where they could observe “one corner” of the garden. However, this testimony is of no consequence since Richards admitted that “the garden had been altered” either by the officers or petitioners after their arrest and before the officers had returned following the preliminary hearing. The same conclusion is reached with respect to Richards’ suggestion that the garden could have been observed by anyone who “climbed to sugar pines” on Perkins’ property, whatever he meant by this statement. Twenty-twenty hindsight vision sheds little light on the issues before this court.
