The surrogate who has not been designated by the patient shall make health-care decisions for the patient based on the wishes of the patient, or, if the wishes of the patient are unknown or unclear, on the patient's best interest.
The decision of a surrogate who has not been designated by the patient regarding whether life-sustaining procedures should be provided, withheld, or withdrawn shall not be based, in whole or in part, on either a patient's preexisting, long-term mental or physical disability, or a patient's economic status. A surrogate who has not been designated by the patient shall inform the patient, to the extent possible, of the proposed procedure and the fact that someone else is authorized to make a decision regarding that procedure.
