(a) such forms of treatment as may be specified for the purposes of this section by regulations made by the Secretary of State;

(b) the administration of medicine to a patient by any means (not being a form of treatment specified under paragraph (a) above or section 57 above) at any time during a period for which he is liable to be detained as a patient to whom this Part of this Act applies if three months or more have elapsed since the first occasion in that period when medicine was administered to him by any means for his mental disorder.

(2) The Secretary of State may by order vary the length of the period mentioned in subsection (1)(b) above.

(3) Subject to section 62 below, a patient shall not be given any form of treatment to which this section applies unless—

(b) a registered medical practitioner appointed as aforesaid (not being the responsible medical officer) has certified in writing that the patient is not capable of understanding the nature, purpose and likely effects of that treatment or has not consented to it but that, having regard to the likelihood of its alleviating or preventing a deterioration of his condition, the treatment should be given.
