(1) The magistrate shall appoint any medical officer in the service of the Government to examine the person suspected to be of unsound mind, and such medical officer shall, if he or she considers the facts warrant him or her in so doing, sign a certificate certifying that in his or her opinion the suspected person is of unsound mind.
(2) Such certificate shall specify in full detail the facts upon which the person signing it founds his or her opinion and shall distinguish facts which he or she has himself or herself observed from facts communicated by others.
(3) The person signing the certificate shall inquire of any persons able to give information as to the previous history of the person and shall state in his or her certificate all matters known to him or her which he or she deems likely to be of service with reference to medical treatment.
(4) No certificate shall have any effect under this Act which purports to be wholly founded on facts communicated by others.
