An appellate court must itself consider the evidence in order to determine whether it was open to the jury to convict, but the appellate court does not substitute its assessment of the significance and weight of the evidence for the assessment which the jury, properly appreciating its function, was entitled to make.
The function of an appellate court where a guilty verdict is challenged on the ground that the evidence is such as to make the verdict unsafe and unsatisfactory is to decide
whether it was open to the jury upon the whole of the evidence to be satisfied beyond reasonable doubt that the accused was guilty: Whitehorn v The Queen [22] ; Chamberlain v The Queen [No. 2] [23] ; Morris v The Queen [24] ; Carr v The Queen [25] . If upon the whole of the evidence a jury, acting reasonably, was bound to have a reasonable doubt, then a verdict of guilty will be unsafe and unsatisfactory [26]
The deference which is due to a jury's verdict, both by reason of the jury's presence at the trial and by reason of its function as the constitutional arbiter of the facts, precludes an appellate court from simply substituting its view of the evidence for the view formed by the jury under proper direction. It is only when an appellate court, giving the verdict appropriate deference, concludes that it was not open to the jury to convict that it is right to set aside a verdict of guilty.
