Cruzan v. Director, Missouri Department of Health, 497 U.S. 261 (1990)
Cruzan v. Missouri Dept.
Does a person have a constitutional right to refuse life-sustaining medical treatment, and can a state require clear and convincing evidence of an incompetent individual's wishes before allowing withdrawal of such treatment?
The Constitution protects a competent individual's right to refuse unwanted medical treatment under the Due Process Clause of the Fourteenth Amendment, but states have the authority to impose procedural safeguards to ensure that an incompetent individual's wishes are followed accurately.
The Supreme Court held that a state can require clear and convincing evidence of a patient's wishes before allowing the withdrawal of life-sustaining treatment when the patient is in a persistent vegetative state and unable to express those wishes themselves.
Cruzan is significant because it established important precedents concerning end-of-life decisions, clarifying the scope of personal autonomy versus state interests within the framework of the Due Process Clause. The decision prompted numerous states to assess and reformulate their legislative and judicial approaches to advance directives and the right to die, reflecting greater respect for individual autonomy in medical decision-making processes.
