The head of the hospital and the Board shall cause the condition of every patient to be reviewed as regularly as practicable, but not less often than every six months, and whenever the head of a hospital or the Board certifies that the patient is not a patient in need of further treatment, the patient shall be discharged. If requested by the patient, all hearings by the Board on the issue of granting a discharge shall be on reasonable notice to the patient's attorney, who shall be afforded an opportunity to attend. In the absence of any attorney, the Board shall notify the Criminal Division of the Superior Court and an attorney shall be appointed as provided in section 7111 of this title.
