Cap. 31 Art. 121ABurden of proof.

(1) In any proceedings against any person for an offence against this Ordinance, it shall not be necessary to negative by evidence any licence, authority or other matter of exception or defence, and the burden of proving any such matter shall lie on the person seeking to avail himself thereof.

(2) When the offence charged is that of possession of, or of selling or dealing in, a drug contrary to the provisions of this Ordinance it shall not be a defence to such charge for the accused to prove that he believed that he was in possession of, or was selling or dealing in, some thing other than the drug mentioned in the charge if the possession of, or the selling or dealing in, that other thing would have been, in the circumstances, in breach of any other provision of this Ordinance or of any other law.
