William Rehnquist,
Cruzan v. Director, Missouri Department of Health…
“ Only because Missouri has arrogated to itself the power to define life, and only because the Court permits this usurpation, are Nancy Cruzan's life and liberty put into disquieting conflict. If Nancy Cruzan's life were defined by reference to her own interests, so that her life expired when her biological existence ceased serving any of her own interests, then her constitutionally protected interest in freedom from unwanted treatment would not come into conflict with her constitutionally protected interest in life. ”
