96 It follows, therefore, that there was a distinction to be drawn between the two terms. Mr Hillman submitted that in this case the incorrect direction could not have had any adverse effect on the applicant's prospects of acquittal. The direction was given with respect to manslaughter and to impose a requirement of proof as to "really" serious injury was too favourable to the defence with respect to manslaughter.
97 That argument has some force, but the difficulty is that the jury's question related both to murder and manslaughter and, in my opinion, it was important in this case that the distinction be maintained so that the jury were not at risk of treating this issue with respect to manslaughter and murder as having the same requirement as to the extent of relevant injury. There remains the risk that the jury, when it returned to its deliberations considered murder as requiring proof only as to serious injury.
98 Although counsel did not object to the directions and seek a redirection I am persuaded that this ground, too, has been made out.
Ground 4: Directions on Causation
99 His Honour directed the jury that for murder they had to be satisfied that the applicant killed the deceased. He added "I will say no more about that", and repeated that expression later. He used the same dismissive words when addressing manslaughter. Mr Priest submitted that in using that language his Honour took the issue of causation from the jury. Furthermore, he submitted, for the jury to address the defence of accident they had to decide which act caused the death so as to decide, in turn, whether the happening of that act (i.e. the wounding by the knife) was a voluntary act (i.e. not an unwilled "accident"), and whether at the moment of that act - if it was voluntary - the applicant was acting in self-defence, with murderous intention, or under provocation and whether - if considering manslaughter - it was a dangerous act in the circumstances.
100 In my opinion, there is nothing in this ground. The directions given by the judge reflected the fact that the trial was conducted on the basis that the fatal injury was known to be the wound to the side and that that wound was caused by a knife held by the applicant. Thus, although the jury had to be satisfied that causation was proved, there was no serious dispute as to that. That is the likely explanation for the absence of any exception to this direction and for the brevity of his Honour's direction. This was a trial with enough complicated issues upon which directions were required to be given, and it was both good sense and good law[52] not to give an additional elaborate direction on a matter which was not in dispute.
101 All of the defences, including accident and defences relating to the state of mind of the applicant, focussed on the happening of the act causing the wound to the side. Thus, unlike the situation in Meyers v. The Queen[53], a case where there were injuries to every part of the victim's body from multiple blows but where the act causing death may have been only one of a number of blows to the head, this was not a case where the act causing death was uncertain. The act causing death was known and the directions to the jury carried no risk of them considering the defences by reference to an act other than the fatal one. As Mr Priest conceded, the case was not fought on the basis that there might have been different intentions, or different exercises of will, as between the two acts causing injury with the knife, nor was it argued that anything might turn on the sequence in which those two events occurred.
102 I reject ground 4.
Ground 2: Cross-examination of defence witness
103 Under this ground, complaint was made that the prosecutor cross-examined the sole witness called for the defence in a way that was unjustified and unjustifiable and was grossly unfair. The judge plainly thought the cross-examination was seriously deficient because he criticised the prosecutor, in the absence of the jury, and then directed the jury to completely ignore the evidence adduced in cross-examination. It seems to me that the criticism of the prosecutor was inappropriate and was based on a misunderstanding of the purpose of the questioning.
104 The defence called Gordon Ingram, a retired senior constable of police who said he knew the deceased man from the time he had been stationed in Tallangatta. He said he had arrested Mr Hanley on several occasions. He said the deceased was very fit and strong. He had a very poor reputation in the community, Ingram said. Counsel asked him about an incident that occurred with Hanley at a supermarket in Wodonga on an occasion before Ingram had left the police force. He recounted that Hanley yelled at him in a loud voice, saying "You're fucking dead, Ingram".
105 In cross examination the prosecutor established that the police force had a system for recording threats made against members but that no entry had been made concerning this incident. Ingram agreed the event must have happened prior to November 1996, when he retired. The prosecutor then asked whether Hanley, together with his brother and a third person (both of whom she named) had made a complaint about the witness, to police at Wangaratta "some years ago". He agreed that was so. He agreed, too, that he did not like Hanley. The judge intervened and asked whether the Crown was challenging the truth of the assertion that there had been such an incident in the supermarket. The prosecutor did not answer the judge directly, nor was pressed to do so in the presence of the jury.
106 In re-examination, the witness said that he had been "bordered (sic) out" of the police force for stress and related issues and that was why he did not make a formal complaint of the threat.
107 No objection was taken to the questioning, by defence counsel. In the absence of the jury, however, he said he was at a loss to understand what was its purpose. The following day the judge criticised the prosecutor for her questioning, and suggested that she had no proper basis for impugning the evidence of the witness. The prosecutor said she could not assert that the evidence was a lie, because she did not know if that was so, since there was no record of the alleged threatening incident. She said the complaint against Ingram had been investigated but that had not led to any disciplinary action or finding against him.
108 As he made clear, the judge's opinion was that the credit of the witness was incapable of being legitimately lowered on the basis that he had been merely the subject of a complaint. That was the equivalent of asserting that being charged with an offence was proof of guilt, his Honour suggested. The judge said there was nothing improper in questions as to the failure to report the threat, but it was wrong for the prosecution to seek to undermine the witness when it had no basis for saying he was lying.
109 When the prosecutor said that the questions had been directed to the possibility of bias, the judge said that that implied that the witness was lying, although the Crown had no reason to suggest that.
110 In my opinion, it is not improper for a cross-examiner to suggest a matter to a witness which would affect his credit if admitted but which, without admission, the questioner would be unable to prove[54]. In this case the prosecutor was not seeking to prove that the witness had done the improper thing that caused complaint to be made against him by the deceased man. Rather, the question raised the possibility that the witness was biased by virtue of the mere fact that he had been the subject of such a complaint from the person whose character he denigrated in his evidence. It seems to me that it was quite proper for the prosecutor to seek to raise that possibility before the jury, given that the deceased man was himself unable to defend his reputation.
111 A trial judge has a wide discretion to disallow questions put to a witness[55] and the atmosphere of a trial, including the manner of the witness, is an important factor which an appeal court is unable to assess when considering the appropriateness of a judge's ruling. In this case the witness obviously had a history of stress-related illness and we can not know how he appeared to the judge.
112 However, assuming, without deciding, that the judge was correct in his contentions as to the inappropriateness of the questions, did the evidence give rise to a miscarriage of justice? The jury were directed to ignore the cross-examination. Counsel for the applicant contended before us, however, that the damage to the defence case had already been done and the direction to ignore the evidence could not restore the situation.
113 In my opinion, given the direction to ignore the evidence there was no miscarriage of justice. By virtue of that direction the applicant could not have lost a chance of acquittal fairly open on account of this evidence, and Mr Priest did not suggest that that would be so, in itself. He relied on this ground, merely, as one to be taken in conjunction with other grounds of appeal.
114 I would not uphold this ground.
Ground 7: Aggregation of errors
115 The final ground of appeal was a wrap-up ground drawing together the complaints under all grounds as establishing that a miscarriage of justice occurred, even if individually, no one ground established that in itself[56].
116 There is no need to address this ground further as I consider that there are several individual grounds that, of themselves, would necessitate the conviction being set aside, subject to the question of the application of the proviso.
The proviso to s.568(1) of the Crimes Act 1958
117 The onus is on the Crown to establish that the proviso ought be applied[57]. In my opinion, the errors are such that the proviso could not be applied in this case. It could not be said that no substantial miscarriage of justice has occurred, as the applicant may have lost a real chance of acquittal[58]. That is particularly so when the grounds I have upheld are taken together.[59]
Conclusion
118 In my opinion, the application for leave to appeal against conviction should be allowed, the conviction be quashed and a new trial be ordered.
