Illinois Statutes Chapter 755. Estates § 35/1. Purpose

§ 1. Purpose. The legislature finds that persons have the fundamental right to control the decisions relating to the rendering of their own medical care, including the decision to have death delaying procedures withheld or withdrawn in instances of a terminal condition.

In order that the rights of patients may be respected even after they are no longer able to participate actively in decisions about themselves, the legislature hereby declares that the laws of this State shall recognize the right of a person to make a written declaration instructing his or her physician to withhold or withdraw death delaying procedures in the event of a terminal condition.
