This chapter may not be construed to condone, authorize, or approve suicide, physician-assisted suicide, or euthanasia, or to permit any affirmative or deliberate act or omission of an act to end life other than to permit the natural process of dying. Death resulting from the withholding or withdrawal of life-sustaining procedures pursuant to an executed POST form and in accordance with this chapter does not, for any purpose, constitute a suicide, homicide, or vulnerable adult abuse or neglect.
