Revocation of detention
90.Section 49 imposes on the responsible medical officer a duty to keep under review the need for the patient to be detained either under a short-term detention certificate or an extension certificate; and requires the certificate to be revoked if the detention criteria are no longer met or if it is no longer necessary for the patient to be detained in hospital on the authority of the certificate. Where a certificate is revoked, notification under subsections (3) and (4) must be made.
