the rule that where the evidence of guilt is circumstantial it is necessary that it should, to a moral certainty, exclude every hypothesis but that of guilt, is not a rule for determining whether evidence is to be believed or not: it has to do, not with conflicting evidence, but with conflicting inferences which may be drawn from the circumstances. It is trite law that if the trial Judge is of opinion that the evidence could not warrant a conviction he may direct an acquittal. If he does not, but leaves it to the jury and they convict, a Court of Criminal Appeal, if of the same opinion, can and should do what he could have done in the first instance; and this is contemplated by s. 6: R. v. George[43]; Halsbury's Laws of England, 2nd ed., vol. 9, pp. 167, 168. In this respect, there is no difference in principle between cases where the evidence is in whole or part direct and those in which it is wholly circumstantial'. It seems to me that exactly the same principle was applied by this Court in Peacock v. The King_[44]_. Barton, J. said:-- 'Whether the fact, or that body of facts which is called the `case' is capable of bearing a particular inference, is for the Court, and unless it is so capable, the Court's duty is to withhold it from the jury, as a single fact or as a case. But when the case is undoubtedly capable of the inference of guilt, albeit some other inference or theory be possible, it is for the jury, properly directed, and for them alone, to say not merely whether it carries a strong probability of guilt, but whether the inference exists actually and clearly, and so completely overcomes all other inferences or hypotheses, as to leave no reasonable doubt of guilt in their minds.[45] O'Connor J. said:-- ' ... can it be said reasonably that the jury were not entitled to draw the inference of guilt against a doctor, charged as the prisoner has been, who will not explain the death of a patient in his hospital, whom he alone was attending, his secret disposal of her body, his burning of her clothes, and his attempt to remove all evidence of her ever having been in his hospital and under his care? They were not bound to draw that inference; another jury might arrive at the opposite conclusion.
