The approved clinician in charge of treatment within section 58(1)(b) (administration of medicine for more than three months) may give a certificate under section 58(3)(b) (appropriateness of treatment without consent) if the clinician considers that complying with the requirement under that provision for the certificate to be given by a registered medical practitioner other than that clinician or the responsible clinician is impractical or would involve undesirable delay.

A registered medical practitioner (or an approved clinician acting in accordance with sub-paragraph (1)) may give a certificate under section 58(3)(b) having consulted only one other person, if the practitioner (or clinician) considers that complying with the requirement under section 58(4) for consultation with two other persons is impractical or would involve undesirable delay.
