Although specifically concerned with the issue of manslaughter, a direction in this form could only have served to confirm in the minds of the jury the impression that they were expected to choose between accepting the evidence of the appellant, in which event, they were to acquit; or, alternatively, accepting the case for the prosecution, in which event they would be entitled to convict. That was, with respect, wrong in law because it failed to accommodate a third possibility, which was that, even if they were not prepared to accept his evidence wholly or in part, it and other evidence, including that of Sgt Graham, might nevertheless suffice to raise a reasonable doubt whether he had the necessary intent to kill or do grievous bodily harm. If the appellant's evidence, even if not accepted wholly or in part, raised a reasonable doubt whether his intention was only to frighten Celap, it might also have raised a doubt whether he in fact possessed the intention to kill or do grievous bodily harm. Factually, the two questions were not mutually exclusive, and in relation to both of them the prosecution carried the onus, as to the first, of eliminating any reasonable doubt, and, as to the second, of proving beyond reasonable doubt that the appellant had the intention required under s 302(1)(a). The direction, in the way it was presented to the jury, went at least part of the way to transferring to the appellant the onus of proving that his intention was as limited as he had testified it was, which was contrary to the decision in Mullen v The King[128]; and on appeal[129].
