Most-quoted passages
The sentences later courts lift from this opinion, ranked by how many decisions quote each — the parts of the opinion doing the work. These counts are smaller than the citation total above because most of the 411 citing decisions cite the case generally; a passage count includes only decisions quoting that exact language verbatim.
“[P]ersons conditionally released to society . . . may have a reduced expectation of privacy, thereby rendering certain intrusions by governmental authorities “reasonable” which otherwise would be invalid under traditional constitutional concepts, at least to the extent that such intrusions are necessitated by legitimate governmental demands. (Citations omitted) Thus, a probationer who has been granted the privilege of probation on condition that he submit at any time to a warrantless search may have no reasonable expectation of traditional Fourth Amendment protection.”
9 later decisions quote this exact passage“by the Probation Officer or any law enforcement officer.”
7 later decisions quote this exact passage“'whenever requested to do so,' " the officers should have requested permission to search and thereby given the defendant the opportunity to grant or refuse permission. ( Id . at p. 763, 97 Cal.Rptr. 302 , 488 P.2d 630 .) The court stated: "To so construe the condition would ... render it utterly meaningless. A 'condition' implies a qualification or restriction; accordingly, a condition to a grant of probation contemplates some limitation upon the probationer's rights. [Citation.] If defendant had the right to withhold his consent to a warrantless search, the protection thereby afforded him would have been as broad as that afforded all other persons under the Fourth Amendment. ... [¶] ... [T]o accept defendant's interpretation of the probation condition would defeat the acknowledged purposes of such a provision to deter further offenses by the probationer and to ascertain whether he is complying with the terms of his probation.”
