It is hereby declared by the legislature of the state of Idaho in enacting chapter 4, title 66, Idaho Code, that the citizens of Idaho who have developmental disabilities are entitled to be diagnosed, cared for, and treated in a manner consistent with their legal rights in a manner no more restrictive than for their protection and the protection of society, for a period no longer than reasonably necessary for diagnosis, care, treatment and protection, and to remain at liberty or be cared for privately except when necessary for their protection or the protection of society. Recognizing that every individual has unique needs and differing abilities, it is the purpose of the provisions of this chapter to promote the general welfare of all citizens by establishing a system which permits partially disabled and disabled persons to participate as fully as possible in all decisions which affect them, which assists such persons in meeting the essential requirements for their physical health and safety, protecting their rights, managing their financial resources, and developing or regaining their abilities to the maximum extent possible. The provisions of this chapter shall be liberally construed to accomplish these purposes.
