California V. Superior Court Of Lake County

In City of Berkeley v. Superior Court (1980) 26 Cal. 3d 515 [162 Cal. Rptr. 327, 606 P.2d 362], we reaffirmed the ancient doctrine that tidelands -- lands between the lines of mean high tide and mean low tide -- are owned by the public, that the state holds these lands in trust for the people for their use for commerce, navigation, fishing and other purposes, and that this trust interest is retained even if the title to tidelands has been conveyed to private persons, unless the conveyance has been made to promote the purposes of the trust.
