It is very well established that the proviso does not mean that a convicted person, on an appeal under the Act, must show that he ought not to have been convicted of anything. It ought to be read, and it has in fact always been read, in the light of the long tradition of the English criminal law that every accused person is entitled to a trial in which the relevant law is correctly explained to the jury and the rules of procedure and evidence are strictly followed. If there is any failure in any of these respects, and the appellant may thereby have lost a chance which was fairly open to him of being acquitted, there is, in the eye of the law, a miscarriage of justice. Justice has miscarried in such cases, because the appellant has not had what the law says that he shall have, and justice is justice according to law.
In the present case the relevant law was not explained to the jury. It was within the jury's province to decide whether they were satisfied that the applicant did an act of such a nature as to be likely to endanger human life. That question was never left to them. It is true that the jury must be taken to have found that the applicant discharged the rifle, and probably that he discharged it at Wynne. It was but a short step to hold that in so doing he did an act of such a nature as to be likely to endanger human life, and the evidence would clearly have supported a finding to that effect. Indeed, there is much to be said for the view that the jury in the present case could not reasonably have made any other finding. Ordinarily, when there has been a misdirection of law, the proviso to s. 689 will be applied if the Crown establishes that if there had been no misdirection the jury would (or must) have come to the same conclusion. However, Wickham J., who delivered the judgment of the Court of Criminal Appeal in the present case, recognized that even if this were established "there might still be a substantial miscarriage of justice if the trial was so irregular that no proper trial had taken place, in that "there had been a serious departure from the essential requirements of the law" ". The Court of Criminal Appeal was right in taking that view of the law, but, in my opinion, wrong in considering that there was no substantial miscarriage of justice in the present case. In Andrews v. The Queen [2] this Court held that the proviso should not be applied where the accused was not in reality tried for the offences for which he was indicted [3] . That case was similar to the present, in that the summing up was more appropriate to a different charge, and the jury were not instructed as to the essential elements of the charge in fact laid. Another case, in which the proviso was not applied because the errors were considered to be funadmental, was Reg. v. Hildebrandt [4] . The jury in the present case were never asked to consider whether the applicant committed an offence against s. 283 (2) and did not find that the elements of an offence against that sub-section had been proved. When a jury has returned a verdict of guilty of a particular crime without having considered whether that crime was committed, the verdict cannot, in my opinion, be sustained by holding that the jury would or should have returned the same verdict if they had considered the proper questions. That would substitute trial by judge for trial by jury.
