5 Cal.4th 725, 855 P.2d 375, 21 Cal. Rptr. 2d 357 (Cal. 1993)
Thor v. Superior Court is a cornerstone California Supreme Court decision at the intersection of bodily autonomy, medical consent, and prisoners' rights.
May the state compel a competent prison inmate to undergo nonemergency, invasive medical treatment over the inmate's objection based on asserted interests in preserving life, preventing suicide, medical ethics, or institutional security?
Under California law, a competent adult has the right to refuse medical treatment, even if the refusal may result in death or serious harm. This right derives from the common law of informed consent and bodily autonomy and carries constitutional dimensions. In the prison context, inmates retain fundamental rights except to the extent reasonably necessary to serve legitimate penological interests (e.g., security or protection of others). The state may not override a competent patient's refusal of nonemergency treatment absent a compelling, narrowly tailored justification that outweighs the individual's autonomy; the mere desire to preserve life or to avoid the optics of "suicide" does not suffice, and nonconsensual treatment constitutes a battery.
No. The California Supreme Court held that a competent inmate retains the right to refuse nonemergency, invasive medical treatment. The state's asserted interests did not justify overriding Thor's refusal. The superior court's order authorizing compelled treatment was vacated.
Thor v. Superior Court is a leading authority in California on the right to refuse medical treatment and its application in carceral settings. It clarifies that competency is the linchpin: if the patient is competent and the situation is nonemergent, the state's generalized interests will not justify compelled treatment. For torts, Thor reinforces that nonconsensual medical procedures are batteries; for constitutional law, it delineates the scope of rights inmates retain; and for health law and bioethics, it affirms patient autonomy as a guiding principle. The case provides a structured balancing approach for courts and practitioners and cautions institutions that forced treatment invites both legal and ethical infirmities absent a truly compelling, narrowly tailored justification.
