*324 Opinion
Petitioner seeks a writ of prohibition to restrain the superior court from, taking further proceedings on an information charging him with marijuana possession. His motion to suppress evidence under Penal Code section 1538.5 was denied by that court. His appropriate remedy is not prohibition, but a writ of mandate directing suppression.
(Greven
v.
Superior Court,
Petitioner’s 12-year-old son, Bill, discovered marijuana in the dresser drawers of his father’s bedroom.. He telephoned the sheriff’s office and arranged to meet a representative of the sheriff at his school. Accordingly, Bill and Sergeant Leeper of the sheriff’s office conferred in the office of the vice principal of the junior high school attended by Bill. Some months previously, he told the officer, he had gone into his father’s bedroom and found seeds and a leafy substance in a dresser drawer. He showed some of the substance to a deputy sheriff who lived nearby. The deputy told Bill that the material was marijuana and disposed of it. Since then, the boy narrated, he had looked into the dresser drawers many times and found hand-rolled cigarettes there along with plastic bags of marijuana. He further reported that his father kept ounce scales in the bedroom. The boy volunteered to get Sergeant Leeper a sample of marijuana from the bedroom but the officer declined until he could ascertain the validity of such a procedure.
The next morning, December 4, 1970, Sergeant Leeper met Bill again. He told Bill it would be legal to have him obtain some evidence. Bill expressed his willingness to get the officer a sample of marijuana from his father’s dresser drawer. Bill told the sergeant that his residence was too far away to walk; that he could not get the sample if his mother were home; that she did not go to work until 4 in the afternoon, but might now be out having her hair done. Sergeant Leeper telephoned Bill’s house. There was rio answer. He then drove Bill to the house. En route the boy asked the sergeant how much he was- to get and Leeper indicated an approximate quantity and suggested that he put the marijuana sample into one of his father’s plastic bags. When they arrived at the house the officer waited in the car while Bill went inside. In a few moments he came out with a plastic bag containing marijuana seeds and a useable amount of marijuana leaf. Leeper took the boy back to school. He had the sample analyzed by a criminalist, who. confirmed its character. Later that day the sergeant signed an affidavit for a search warrant, which incorporated by reference his *325 written report of the events. A warrant was obtained and executed that afternoon, and a quantity of marijuana and related paraphernalia were seized in petitioner’s home.
At the hearing of the suppression motion Bill testified that he was not “supposed” to enter his father’s bedroom. He was not asked whether he told Sergeant Leeper of that restriction.
Petitioner’s motion to suppress left some uncertainty as to the objective of his motion. Although, strictly speaking, his written motion sought suppression of marijuana taken “by various levying officers,” his accompanying points and authorities made it quite plain that the motion sought suppression of the marijuana sample which Bill had delivered to the officer, as well as the contraband later seized under the search warrant.
By restricting government intrusion into the privacy of the family home, the Fourth Amendment conceivably incorporates some elements of the biblical Fifth Commandment. We need not embark on that inquiry because established Fourth Amendment standards adequately dispose of the case. The Fourth Amendment is violated by a warrantless police search of a dwelling when the search’s only justification is probable cause to believe that contraband is there.
(Agnello
v.
United States,
The Attorney General relies upon the substantial evidence rule. He points to a trial court finding that the boy was not a police agent but a voluntary actor whose offer to fetch a sample of his father’s contraband was accepted by the police. The deference owed to the trial court’s factual finding gives way when the finding is entwined with a constitutionally in-acceptable test.
(Lustig v. United States,
The Attorney General correctly abstains from arguing a consent theory. There are cases where a member of the family consents to a police search of jointly occupied premises. (See, e.g.,
Vandenberg
v.
Superior Court,
A search warrant obtained upon information acquired by an illegal search is itself invalid.
(People
v.
Roberts, 47
Cal.2d 374, 377 [
We measure this contention by the “fruit of the poisonous tree” rule. Originally enunciated in
Wong Sun
v.
United States,
Sergeant Leeper’s affidavit for the search warrant incorporated by reference a fairly extensive report of his investigative activity. His interviews with petitioner’s son played a central part in the investigation and his investigative report. The illegal joint expedition to fetch a marijuana sample from the father’s dresser drawer and the sheriff’s confirmation of the sample’s physical character formed a substantial element in the report. The magistrate had the function of deciding whether the affidavit disclosed probable cause.
(Aguilar
v.
Texas,
Let a peremptory writ of mandate issue directing the respondent court to grant petitioner’s motion to suppress evidence received by the sheriff on December 4, 1970, both that obtained prior to the search warrant and that taken under the search warrant.
Bray, J., * concurred.
The petition of the real party in interest for a hearing by the Supreme Court was denied October 14, 1971.
