No further complaint was made on this matter.
37 Mr. Haesler submitted that the trial judge put the alleged lie about the jacket as not merely going to credibility, but as giving some positive support to the Crown case; and did so without giving warnings as required by Edwards v. The Queen (1997) 178 CLR 193. The additional direction did not withdraw the previous directions, but indeed compounded the situation in that the reference to "necessarily guilty" suggested that it may still be some evidence supporting guilt.
38 Mr. Rowling submitted that the Crown relied on the lie only as going to credit, and the directions were correct. He submitted that the further direction was in accordance with Zoneff v. The Queen (2000) 200 CLR 234 at [22]-[24]. Mr. Rowling referred to R v. Hodge [2002] NSWCCA 10 at [24], where there is reference to what was said in Osland v. The Queen (1998) 197 CLR 316 at [44].
39 In my opinion, the question put in cross-examination carries the suggestion that the appellant was lying because he knew the truth would tend to implicate him in the crime of which he was accused. The direction originally given, to the effect that the Crown said that if the appellant was lying about the jacket it was likely that he was lying about whether he took part in the robbery, did convey to the jury that this lie could give direct positive support to a finding of guilt. The same can be said of the later direction that the Crown said the appellant was lying about the jacket because he was lying about his participation or non-participation in the robbery.
40 If the lie was to be relied on only on the question of credibility, a direction could have been given to the effect that, if by reason of the lie the jury disbelieved the appellant's evidence, they could leave that evidence out of account in deciding whether or not the remaining evidence in the case did establish guilt beyond reasonable doubt. I think that to suggest that the lie in question could support a finding that the appellant was lying when he said he did not commit the offence is tantamount to saying that the lie could directly support a finding that the appellant did commit the offence, which goes beyond using the lie on the question of credibility.
41 When the trial judge gave the further direction, he told the jury that if they considered the appellant was lying about the jacket, they could take this into account on the appellant's credibility, but must not "take from that the conclusion that he is necessarily guilty of the offence with which he is charged". This was not in my opinion appropriate to ensure that the jury did not take the lie as supporting guilt except to the extent that it affected the appellant's credibility: although the jury was told that they could not use the lie to conclude the appellant was "necessarily guilty", they were not told, as suggested by Zoneff, that they should not reason that the lie was evidence supporting a finding of guilt. In my opinion, what was said in Osland at [44] is relevant to this case:
44. Where, as here, there is a risk that a jury might treat lies as evidence of guilt, the preferable course is for the trial judge to ascertain precisely what use the prosecution contends may be made of the evidence in question. And if the evidence is to be left to the jury as evidence of guilt, it should be instructed as required by Edwards v. The Queen (1993) 178 CLR 193 at 210-211, per Deane, Dawson and Gaudron JJ. If not, it should be instructed that the evidence is relevant only to the credit of the accused. Only by adopting that course can a trial judge guard against "a perceptible risk of injustice".
42 Thus, there is in this case a real question whether an Edwards direction should have been given. In this case, however, the lie in question was clearly identified, as was the basis on which it could be inferred that the appellant would have known that the truth would tend to implicate him. The jury were not told that there might be other reasons to lie apart from realisation of guilt, such as panic, to escape an unjust accusation, to protect some other person or to avoid a consequence extraneous to the offence; nor that, if they considered the lie had such an explanation, they could not regard it as supporting guilt (Edwards at 211). However, in this case the only plausible alternative reason was the second of those mentioned, ie, that, although the appellant did not commit the offence, he lied about the jacket so as to weaken the Crown case that he did commit it and thereby defeat an unjust accusation.
43 In my opinion, the question comes down to whether the failure of the trial judge to identify the way in which the lie might have been relevant to support guilt otherwise than merely through affecting the credibility of the appellant, and to draw to the jury's attention the possibility that such a lie was to protect the accused against an unjust accusation, amounted to an error in the summing up which was material and involved the risk of a miscarriage of justice. On the whole, I am not so satisfied. Quite apart from the alleged lie, it was a strong circumstantial case; and the acquittal of the appellant depended essentially on whether the jury were left with a reasonable doubt as to whether the appellant's account of how he came into possession of the car might possibly be true. The jury must have accepted, as they were entitled to, that the car was correctly identified as the car involved in the robbery; and in those circumstances, unless the jury reasonably considered that appellant's evidence about his acquisition of the car might possibly be true, conviction was almost inevitable. Thus, while a conclusion that the appellant lied about the jacket, and thus had poor credibility, did not directly support a finding of guilt, it gave strong indirect support to it. Furthermore, I do not think the appellant would have been assisted by having the jury asked to focus on the question whether a lie about the jacket would have been to defend himself against an unjust accusation, rather than made out of a realisation that he had worn the jacket and that the truth about the jacket would implicate him.
44 For those reasons, in my opinion this ground of appeal also fails.
