(a) Any individual who has entered a human development center by voluntary admission in accordance with the provisions of § 20-48-406(b) may be withdrawn from the center at any time upon the application of the parent or guardian who has legal custody of the individual, provided the parent or guardian shall have first given to the Board of Developmental Disabilities Services thirty (30) days' notice in writing of his or her intention to withdraw the individual from the center.
(b) An individual committed by order of the circuit court to a center or transferred from another institution shall not be discharged therefrom until, in the judgment of the board and the superintendent of the center, his or her condition justifies the discharge. Whenever the board in its sole judgment determines that the individual should be discharged, the discharge shall be by order of the board, and the board shall certify the discharge to the circuit court of the county making the order of commitment.
