The above misdirections about onus of proof must be considered against the background of a number of passages in the learned trial judge's summing up in which he carefully and correctly explained to them the requirements of the criminal onus and standard of proof. They must, however, also be considered against a background where, on a number of occasions, his Honour directed the jury in terms which indicated that the overall question for them essentially involved the making of a "choice" between prosecution and defence evidence: "in many ways this case boils down to who do you believe"; "You may well think that the attitudes are so far apart that you have to make a choice"; "The case may well be one as I have put to you before, where the real question is who do you believe on the whole of the evidence, [the complainant] or the accused?" Provided that they are accompanied by clear and unequivocal directions about the criminal onus and standard of proof, express or implied references in a summing up to a "choice" between particular witnesses are, no doubt, sometimes unavoidable and commonly unobjectionable. The main significance of the directions about having to make a "choice" lies, in the present cases, in their clear suggestion that the "real question" in the cases turned upon a mere "choice" between the evidence of the complainant and that of the accused and in the possible contribution of that suggestion to the overall effect of the misdirections about onus of proof. Their significance in that regard is underlined by the linking, in the passage which I have quoted in the preceding paragraph, of satisfaction of "a belief in the accused" with a failure to be satisfied beyond reasonable doubt of the ingredients of the charge. It was heightened, rather than reduced, by his Honour's further direction, after the completion of his summing up, that his previous statements to them that the case "might well be" one "about whom you might believe" was "a gross simplification in many ways and I am sure you will bear in mind what I have put to you about considering the evidence carefully and weighing it very carefully".
