Presumption as to genuineness of certified copies
81.—(1)  The court is to presume to be genuine every document purporting to be a certificate, certified copy or other document which is by law declared to be admissible as evidence of any particular fact, and which purports to be duly certified by any public officer in Singapore or any officer in Malaysia who is duly authorised thereto, if such document is substantially in the form and purports to be executed in the manner directed by law in that behalf.
(2)  The court is to also presume that any officer by whom any such document purports to be signed or certified held, when the officer signed it, the official character which the officer claims in such document.
