If, in respect of a patient who is absent from a hospital pursuant to section 62 or 71, a medical practitioner furnishes to the medical superintendent, before the date on which the period for which the patient's absence is allowed expires, a certificate to the effect that, in the opinion of the medical practitioner, the detention of the patient in the hospital is no longer necessary, the medical superintendent may, on receiving the certificate, discharge the patient.
