The proviso
97 It is plain from the principles set out by Johnson J and what was said in the passages quoted from Solomon that, simply because a trial judge leaves to the jury a case or arguments not relied upon by the Crown, it does not follow that there has of necessity been a miscarriage of justice. Nor is it such a defect in the trial that rule 4 cannot apply. Counsel might conceivably overlook a misstatement of the law or some erroneous recital of fact made in a lengthy summing up. But if by putting an argument or a case to the jury that was not put by the Crown some real unfairness has arisen to the accused, it is difficult to imagine that defence counsel would not object. In both Solomon and Robinson complaint was made at the trial.
98 Here defence counsel never raised any objection about this part of the summing up notwithstanding that he asked the Judge to tell the jury that they could not convict without accepting at least in part the evidence of Wigney. As the Crown Prosecutor at the hearing of this appeal submitted, it is difficult for counsel for the appellant now to assert that the summing up deprived the appellant of a fair trial when defence counsel made no such complaint. Nowhere did defence counsel assert that in some way the appellant had been prejudiced by the Judge putting to the jury that the Crown was contending that they could convict the appellant even if they rejected the evidence of Wigney. Yet he had made a submission to the jury to the contrary and asked the Judge for a direction to the contrary. In those circumstances it is difficult to understand how defence counsel could have let the situation go without any complaint that this was not the Crown's case or that he had been deprived of the opportunity to meet that case if he truly believed that in some way the appellant was being prejudiced by the manner in which the Crown case was being left to the jury.
99 The Crown before this Court submitted that there was a tactical advantage in defence counsel not asking the Judge to specify those facts that the jury could rely upon in the absence of the evidence of Wigney because it suited him to run the case on the basis of the evidence of Wigney, bearing in mind the warning that the Judge was required to give under s 165, rather than to meet a case arising from the circumstances and facts other than those arising from Wigney's evidence.
100 One of the difficulties in the present case was that on the evidence of Wigney there were only two rounds obtained with the weapon. One round was discharged in the appellant's unit and the other in the incident the week earlier about which the jury knew only that the round had been discharged in the street. Wigney's evidence was that he obtained the other rounds from an offence that he committed and in respect of which the appellant was not involved. Therefore, it was the appellant's case in cross-examination of Wigney that he believed that the rounds in Wigney's possession had been used. There was some issue about when Wigney obtained the other rounds.
101 In any event, if the evidence of Wigney were disregarded, the only evidence before the jury was that the appellant was involved in the robbery and knew that Wigney had the weapon that was in evidence at the trial. There was, however, no evidence as to what the appellant knew about that weapon, for example whether it was capable of discharging a live cartridge. There was certainly no evidence that the appellant knew that there was ammunition in the weapon or even available for the weapon. Without the evidence of the appellant's knowledge of the weapon given by Wigney, it was impossible, in my view, for the jury to conclude beyond reasonable doubt that the appellant contemplated that it might be discharged.
102 It follows that, in my opinion, it was not open to the jury to convict the appellant in the absence of Wigney's evidence and, as I have indicated, the Crown never submitted to the jury that it could. The Judge was in error in rejecting defence counsel's submission requesting such a direction and further in error in directing the jury to the contrary.
103 But in my opinion these errors are not so fundamental that the proviso could not be applied. This is so even accepting that the proviso might not be applicable where there has been "a significant denial of procedural fairness": Weiss v The Queen [2005] HCA 81; 224 CLR 300 at [45]. So, if this Court itself concluded from an examination of the whole of the record of the trial, that the appellant was guilty of the offence of murder there would be no miscarriage of justice occasioned by the error of the trial judge: Weiss at [41]. The Court is to take into account both the "natural limitations" that attend such an examination and the fact that the jury did convict the appellant. The purpose of the proviso is "to avoid the needless retrial of criminal proceedings": Weiss at [47].
104 I am prepared to approach this matter on the basis that any conviction founded upon the evidence excluding that of Wigney would be unsupportable. I cannot accept, and I do not believe the jury would have accepted, the prosecutor's submission that the appellant would have known that the weapon was loaded because he would have understood that a loaded firearm was necessary to carry out an offence of this nature, whether it be classed as a professional armed robbery or not. As I have already indicated, without some at least of the evidence of Wigney the Crown could not prove that the appellant knew that the weapon was even capable of discharging: it could have been a replica.
105 I would be prepared to accept in full the evidence of Wigney notwithstanding the caution with which his evidence was to be approached. Clearly he was himself a criminal who had committed at least two armed robberies to the jury's knowledge. There is no suggestion that he did not know the firearm was loaded at the time of the robbery and he cocked it in order to discharge it when finding himself in difficulties. Generally, therefore, he was not a witness of credit. Further, he had a reason to fabricate evidence to assist the police in order to secure a discount of his sentences.
106 But otherwise his evidence appeared to me to be credible and on the transcript at least he was a convincing witness. Apart from the reward of a discount in sentence there was no reason for him to fabricate his evidence and a large part of it was not in dispute. His disputed evidence that the appellant had a knife was supported by accounts of the witnesses at the robbery who gave evidence that the appellant appeared to be armed and made threats to the witnesses of death. In light of the fact that he admitted to taking the weapon, cocking it and firing it, this was hardly a case of him playing down his part in the offence at the expense of the appellant. The appellant gave no account to be placed along side that of Wigney and that might have raised a reasonable doubt about Wigney's account.
107 There were minor variances between the account in the witness box and what Wigney had said on other occasions, but they did not to my mind indicate that he was not what he appeared to be so far as his credibility was concerned, a person prepared honestly to give evidence about the involvement of a co-offender in his offence notwithstanding that it was for reward. It was significant to my mind that he had volunteered his participation in the robbery and the killing to police when he was in custody for another offence. The fact that he did not then reveal the identity of the appellant as his co-offender does not seem to me to be of significance in light of the fact that the information he gave them as to a co-offender named Garry was generally consistent with his later account of the involvement of the appellant. There was no dispute as to the presence of the appellant at the robbery or his role generally but only those matters that implicated the appellant as having knowledge that the weapon was loaded. It is not apparent from his evidence that he was down playing any of his criminal activity that he was asked about.
108 Although I would be satisfied beyond reasonable doubt on the evidence of Wigney that the appellant loaded the weapon before the robbery, I am prepared to put aside those parts of his evidence that were in dispute. If that is so, the appellant knew a relatively short time before the robbery that Wigney had a weapon that was capable of discharging a round because of the accidental discharge of the weapon at the flat. He took part in an armed robbery on commercial premises knowing that Wigney had that weapon but not knowing whether or not he had any ammunition for it on that evening. In those circumstances I am satisfied beyond reasonable doubt that the appellant must have contemplated that the weapon might be loaded and, therefore, might have been discharged during the course of the robbery.
109 I would dismiss the appeal against conviction.
