Where in any prosecution under this Act it is relevant to ascertain particulars as to the registration or licensing of any vessel or conveyance registered or licensed in any port or place in Malaysia or in Singapore, a certificate purporting to be signed by the officer responsible under any written law for the time being in force in the Federation or any part thereof or in Singapore for such registration or licensing shall be prima facie evidence as to all particulars concerning such registration or licensing contained therein, and the burden of proving the incorrectness of any particulars stated in such certificate shall be on the person denying the same.
