[47] Even if that conclusion is wrong, what follows? I would reject the submission that an alternative verdict must be left to the jury whenever there is some evidence to support it, regardless of the interests of justice. Counsel cited no authority for that proposition, which is not surprising. I very much doubt whether any exists and there is a decision of this Court which arguably is to the contrary.[28] Unfortunately, neither side in the present appeal favoured the court with argument regarding the proper test, or even with an identification of relevant circumstances. Few of the relevant authorities were referred to. Counsel for the appellant did not attempt to amplify his submission regarding a miscarriage of justice, nor to identify the circumstances of the case said to give rise to such a miscarriage. Counsel for the respondent did not advance any argument to support the verdict in the event that his primary submission was not accepted.[29] I protest this lack of assistance. The authorities which counsel did cite, particularly Rehavi and Willersdorf, raise a number of very complex issues. Those issues can be the more clearly discerned in a number of decisions not cited to us: R v Elfar,[30] R v Le Doan,[31] R v Kane[32] and R v King.[33] Those cases show the sharp division of opinion which the principal case relied upon by the appellant, Rehavi, has aroused in other States and within those States. They discuss the issues, in some cases at considerable length. They provide an essential context for understanding the implications of Rehavi and Willersdorf.
