"Of course, she says does she not, that she thought they were steroids. If you find that she was in the possession of these drugs and the drugs contained heroin, the defendant on her evidence must prove, to the standard so it is more likely or more probable than not, that she was a bailee, or if you like an agent who had no right to open the package and no reason to suspect that the contents were illicit or drugs, or that she had no knowledge of or had made a genuine mistake as to the nature of the contents, and had received the package innocently and had no opportunity to acquaint herself with its actual contents. Now, she must show that on the evidence to you, but it does not detract from what I said a few moments ago. At all times, the Crown must prove her guilt. It is not for Miss M to prove her innocence, and she having raised her apparent lack of knowledge, then the Crown will have to prove it from evidence that has been deployed in this case against her."
