From Wednesday's Firefighters4Freedom v. City of L.A. (see here for more on the non-privacy-based challenges in the case), a part of the opinion that all three judges endorsed:
Firefighters4Freedom, a nonprofit corporation "whose mission is to support the constitutional rights of firefighters in the City of Los Angeles during the COVID-19 pandemic," sued the City of Los Angeles over the City's 2021 COVID-19 vaccine mandate for City employees. Firefighters4Freedom sought declaratory and injunctive relief based on allegations the vaccine mandate exceeded the City's authority under its police powers, violated the firefighters' right to privacy under the California Constitution, and violated the firefighters' due process rights….
"Unlike the federal Constitution, the California Constitution expressly recognizes a right to privacy: 'All people are by nature free and independent and have inalienable rights. Among these are enjoying and defending life and liberty, acquiring, possessing, and protecting property, and pursuing and obtaining safety, happiness, and privacy.'" …
In Hill v. NCAA (Cal. 1994) the Supreme Court articulated a two-part inquiry to determine whether the plaintiff's right to privacy under article I, section 1 has been violated. First, the plaintiff must demonstrate … "'(1) a legally protected privacy interest; (2) a reasonable expectation of privacy in the circumstances; and (3) conduct by defendant constituting a serious invasion of privacy.'" "Second, if a claimant satisfies the threshold inquiry, '[a] defendant may prevail in a state constitutional privacy case by negating any of the three elements … or by pleading and proving, as an affirmative defense, that the invasion of privacy is justified because it substantively furthers one or more countervailing interests.' [Citation.] 'The plaintiff, in turn, may rebut a defendant's assertion of countervailing interests by showing there are feasible and effective alternatives to defendant's conduct which have a lesser impact on privacy interests.'" …
Firefighters4Freedom alleged City firefighters have a legally protected privacy interest in their bodily integrity…. The right to bodily integrity (also called personal autonomy) is protected under article I, section 1 of the California Constitution. (See In re Qawi (Cal. 2004) ["The right of privacy guaranteed by the California Constitution, article I, section 1 'guarantees to the individual the freedom to choose to reject, or refuse to consent to, intrusions of his bodily integrity.'"].) …
