The legislature recognizes that there are many adult citizens of the state who, because of the infirmities of age, disabilities or like incapacities, are in need of protective services. Such services should, to the maximum degree of feasibility, allow the individual the same rights as other citizens, and at the same time protect the individual from exploitation, neglect, abuse and degrading treatment. This chapter is designed to establish those services and assure their availability to all persons when in need of them, and to place the least possible restriction on personal liberty and exercise of constitutional rights consistent with due process and protection from abuse, exploitation and neglect.
