Constitution. California's state constitution guarantees the right of privacy to every state citizen (Cal Const. art. I, § 1). This provision applies to both public (i.e., governmental) entities and private companies and individuals. Individuals have a right to sue private parties, including an employer, for any violation of the state's privacy guarantees. The provision has been used successfully in court on several privacy-related grounds, including drug testing. In considering whether an individual's right to privacy has been violated, California courts use a test that balances the privacy rights of the individual against the rights of another to invade that privacy.
Common law. California recognizes all four common-law invasion of privacy claims: intrusion upon solitude or seclusion, public disclosure of private facts (e.g., unreasonable publicity given to one's private life), false-light privacy (e.g., publicity that normally places the other in a false light before the public), and appropriation of one's name or likeness (Hill v. Nat’l Collegiate Athletic Ass’n, 865 P.2d 633 (1994)).
