But remember, it is wrong to ask yourselves, in the context of the accused, why should [the complainant] lie? That's not a question which the accused can answer. It is a question which requires a speculative answer, and the conclusion in this case is not to be reached by speculation.
It is impossible for the accused to account to you for what he says is a false story told by [the complainant]. He is unable to see into the mind of [the complainant], and so the question is unfair.
You will see now that to question yourselves in this way is actually reversing the onus of proof, and you know that must not occur. The onus stays with the Crown, and the accused is innocent until you are satisfied beyond reasonable doubt as to his guilt.
If you conclude that [the complainant] has such a motive that, in itself, would not necessarily mean that he was not telling the truth, but it will be relevant to your assessment of his credibility and the weight which you are prepared to give his evidence in the Crown case.
If you understand that you have been asked by the Crown to consider that there is a suggestion by the defence that the many persons whose names were mentioned to you, who were Crown witnesses, are involved in a conspiracy with the accused as its target, then I want you to carefully understand what I know say to you.
Firstly, [counsel for the accused] has made it clear to you that the defence is not suggesting that there is a conspiracy by the prosecution witnesses. The accused's defence is that he did not do it, he did not have sexual relations with [the complainant] at all in 1987 or at any time. Secondly, to the extent that there is a question posed for the accused to answer, 'why would the Crown witnesses conspire?', I repeat what I have said to you a moment ago about the question 'why would [the complainant] lie?' It is not a question which can concern you, because to do so means that there is some expectation on the accused to answer it. As you know, there can be no such expectation, because to have it would require speculation on your part, and would reverse the onus of proof. You know that is wrong. There is no onus on the accused. The onus is always with the Crown to prove each count beyond reasonable doubt, and that cannot be achieved by asking that the accused supply answers and explanations where there is no obligation upon him to do so.
As I have direct you, the law is that such a question cannot be asked, even rhetorically, and you should put it out of your minds and concentrate on whether the evidence that you accept beyond reasonable doubt is sufficient to discharge the onus of proof borne by the Crown in relation to each separate count and not go off into areas requiring speculation.
Ask yourself whether the evidence which you accept supports [the complainant] so that you can be satisfied that his evidence is reliable.
