The argument that the approach of a court of criminal appeal in a case where there has been a conviction upon circumstantial evidence should be different from that of such a court when the evidence is direct was indeed supported by a number of citations that do credit to the industry of counsel for the applicant. The authorities relied upon were principally Canadian cases, viz. Fraser v. The King [1] ; R. v. Comba [2] ; R. v. Dawley [3] and R. v. McGrath [4] . In these cases statements are to be found to the effect that, when the evidence of guilt is circumstantial, a court of criminal appeal must set aside a conviction where it seems to the court that the evidence does not negative as a reasonable hypothesis every hypothesis but that of guilt. Nevertheless, I am in no doubt that when what was substantially the same argument as we have heard was addressed to the Court of Criminal Appeal in New South Wales in the cases of R. v. Rothery [5] and R. v. Cable [6] the correct answer was given to it and I am satisfied to repeat some words used by Jordan C.J. delivering the judgment of the Court in the later case, with the observation that it is with competing explanations rather than inferences that the Court is concerned in this sort of case. The Chief Justice's words are: - "If I have correctly understood Mr. Windeyer's argument, it is that the approach of the Court to an appeal in a case in which the conviction has been obtained on circumstantial evidence should be quite different from what has been held to be appropriate where the evidence is direct. In the latter type of case, it may guide itself by what was said by the High Court in Ross v. The King [7] "If there be evidence on which reasonable men could find a verdict of guilty, the determination of the guilt or innocence of the prisoner is a matter for the jury and for them alone, and with their decision based on such evidence no Court or Judge has any right or power to interfere. It is of the highest importance that the grave responsibility which rests on jurors in this respect should be thoroughly understood and always maintained" [8] , or as it has been sometimes put, s. 6 is not intended to substitute for trial by twelve jurymen who have seen and heard the witnesses trial by three Judges who have not. But in the former type, it is said, the Court of Criminal Appeal has a completely free hand. If, on reading a transcript of the evidence, it thinks that it would itself have given a different verdict, that is enough, not only to entitle, but to require, it to set aside the jury's verdict. I entirely disagree with this contention, for which there is no shadow of authority; and there is nothing in the Act to support it. It may be pointed out also that it was held by this Court in R. v. Rothery [1] , in which the High Court refused special leave to appeal, that 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 [2] ; 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" [3] . It seems to me that exactly the same principle was applied by this Court in Peacock v. The King [4] . 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" [5] . 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. But I have no hesitation in affirming as a matter of law that the verdict which the jury did find was open to them on the evidence" [1] .
