However, he also said that the appellant responded to some of Dr Spencer's questions " spontaneously and coherently ".
41 As to the conversation referred to in [27] above, the following exchange took place (T.328-329):
"Q. What you ended up recording was the accused making a reference to having done something bad and saying, 'I'm in real trouble'?
A. Yes.
Q. And the doctor a little bit after that asking him about suicide and the accused saying, 'Because I did something bad'?
A. That's right.
Q. And then the doctor, not the accused, asking the question, Do you mean stabbing the lady'?
A. That's correct.
Q. So that in that conversation you're clear, aren't you, that the first reference to stabbing the lady came from Dr Spencer?
A. Yes.
Q. Not from the accused?
A. No. No. it definitely came from Dr Spencer.
Q. And the response that you recorded from the accused was, am I right, this: 'Yeah, I don't know where the knife came from, I just had it' and then he went on to say that he'd warned her?
A. That's correct.
Q. As to the actual events in the park, you're clear, are you, that the only thing that the accused said to Dr Spencer in your presence was, in substance, 'I did something bad', but it was then the doctor who asked, 'Do you mean stabbing the lady?', and the accused's response was, 'Yeah, I don't know where the knife came from; I just had it'?
A. That's correct.
Q. And that was a part of the conversation that you took particular interest in - a particular interest in?
A. Yes, I did.
Q. And you listened carefully to that part of it?
A. Yes, I did.
Q. It is true then, is it, that during that conversation with Dr Spencer the accused did not say, 'I went to the caravan park'?
A. No, he didn't.
Q. He didn't say, 'I chased a woman there'?
A. No, he didn't.
Q. And he didn't say, 'I stabbed her in the park'?
A. No, he didn't.
Q. And, as to that, because of the situation you were in, taking care about those things, you can be definite?
A. Yes, I can be."
42 Senior Constable Neville had been cross examined earlier on the reliability of his note of what he had heard the appellant say to Dr Spencer (T.322):
"Q. But you were also listening with care to see what, if anything, the accused said?
A. Yes.
Q. In the conversation that you then heard between Dr Spencer and the accused, were you in a position to hear all of it?
A. Yes.
Q. And you're confident that you did?
A. Yes.
Q. You didn't actually record that conversation as it was happening, did you, but you have explained, soon after, once you had gone with the accused when he was transferred to the intensive care unit?
A. Yes, that's correct."
43 The appellant submits that the conversation between himself and Dr Spencer given in evidence by Senior Constable Neville was of particular significance to the Crown's contention that the appellant took the overdose of Oxazepam after the stabbing in an attempted suicide. The context of that conversation was at odds with statements made by the appellant (including those to Dr Spencer) in which he said that he had taken the Oxazepam prior to the stabbing. As the timing of the ingestion of the overdose was a critical feature of the Crown's case on the issue of intent, it was submitted that the trial judge should have excluded the evidence pursuant to s 137 of the Evidence Act or, alternatively, should have given a warning to the jury in accordance with s 165(1)(c).
44 It was acknowledged by the appellant that his trial counsel had not sought to have the conversation excluded from evidence pursuant to s 137; nor had he requested the trial judge to warn the jury that Senior Constable Neville's evidence of what he had overheard the appellant tell Dr Spencer may be unreliable due to the appellant's medical condition at the time. However, it was submitted that Rule 4 of the Criminal Appeal Rules should not be applied in the circumstances, as the conversation given in evidence by Senior Constable Neville was of central importance to the Crown case. The trial judge's failure either to exclude it pursuant to s 137 or to warn the jury in terms of s 165 resulted in a miscarriage of justice in that the appellant was thereby deprived of the real prospect of an acquittal on the charge of murder.
45 The significance of the absence of an application for further directions has been referred to by this Court on numerous occasions. It is sufficient for present purposes to cite the following passage from the judgment of Howie J (with whom Giles JA and Carruthers AJ agreed) in R v Moussa [2001] NSWCCA 427, where his Honour observed at [60] and [63]:
"It may well be the case that, if the failure to seek a direction or warning was a result of a considered and competent decision made for tactical reasons, it would be virtually impossible for the appellant to obtain leave to rely upon the point because no miscarriage of justice could have occurred. But in my view it should not be taken to be the case that leave will automatically be granted simply because the proffered explanation is that counsel overlooked the point or was unaware of the law on the subject. Nor is it more likely that leave will be granted simply because counsel can no longer indicate why the point was not taken at the trial.
……
At the end of the day the question, with which this court is concerned, is whether the conduct of the trial may have resulted in a miscarriage of justice and that question is not necessarily answered in favour of the appellant simply because of decision, errors or oversights by counsel falling short of incompetence. Trial counsel has a duty both to the client and the court to take objections or seek redirections where appropriate: Regina v Roberts [2001] NSWCCA 163. Like other aspects of the conduct of defence counsel during the course of the trial, a failure to seek a direction or warning will not necessarily result in a miscarriage of justice, even if counsel was negligent: Regina v Birks (1990) 19 NSWLR 677 at 685. If leave is required under Rule 4, then the appellant has to persuade this court that a miscarriage of justice may have occurred before leave is granted: Tripodina and Morabito (1988) 35 A. Crim. R. 183 at 191; Regina v Williamson & Morrell (NSWCCA, 11 October 1991). On the other hand, if the point is taken at trial, the Crown will have the onus of persuading this court that there had been no substantial miscarriage of justice: Clarke (1995) 78 A. Crim. R. 226."
46 More recently, in TKWJ v R (2002) 76 ALJR 1579, a case in which trial counsel had made a decision not to call certain evidence, which omission was later said to have resulted in a miscarriage of justice, Gleeson CJ (at [17]) said this:
"Trial counsel made a decision not to call certain evidence. Viewed objectively, it was a rational tactical decision, made in order to avoid a forensic risk. It did not make the trial unfair, or produce a miscarriage of justice."
