The evidence of Mark Johnson
33 Both appellants complain that the learned trial judge failed adequately to warn the jury that the evidence of Mr Johnson might be unreliable. I have already referred to the importance of his evidence in the Crown case. He claimed to have seen Mr Taranto shoot the complainant, and it was from his evidence that it might have been inferred that Ms Kelly knew that Mr Taranto was armed. Obviously, his credibility loomed large.
34 He was cross-examined about his substantial criminal record, which included offences involving the use of firearms. He was also a registered police informer, and he acknowledged having gained a benefit on penalty for a charge which he faced as a result of his willingness to give evidence against the appellants. His Honour dealt with these matters in summing-up. It was submitted that these directions were insufficient but, in the light of the matter to which I am about to refer, I do not find it necessary to decide this.
35 The major argument in support of this ground was that his Honour declined to give what might be loosely described as an accomplice direction: s165(1)(d) of the Evidence Act, and gave no adequate reasons for that decision. Section 165 requires a trial judge, upon the request of a party, to warn the jury about evidence which may be unreliable unless he or she considers that there are good reasons for not doing so. Without purporting to be exhaustive, subs(1) sets out certain categories of evidence which may be unreliable, including:
(d) evidence given in a criminal proceeding by a witness, being a witness who might reasonably be supposed to have been criminally concerned in the events giving rise to the proceeding…
36 In the course of the summing-up, a direction was sought by counsel then appearing for Mr Taranto on two occasions. The first occasion is recorded as follows:
SEGAL : … perhaps more controversially your Honour I ask your Honour to give a direction in the nature of an accomplice direction.
HIS HONOUR: In relation to who?
SEGAL: With respect to Mark Johnson.
HIS HONOUR: Well I won't.
37 On the second occasion the following exchange occurred:
SEGAL: But another shorthand word I've mentioned earlier your Honour, when I asked for an accomplice direction that was a shorthand way of referring to the s165D (sic) direction where a witness who might reasonably be supposed to have been criminally concerned in the events giving rise to - -
HIS HONOUR: Yes. Well I don't reasonably suppose that Mr Johnson was concerned in the offence, do you?
SEGAL: It's because the accused has given evidence that he didn't (sic) raise as the reasonable hypothesis, or the reasonable examination (sic) that Mark Johnson did.
HIS HONOUR: As I said earlier Mr Segal we are concerned with facts, we are not concerned with fantasy.
SEGAL: Well, your Honour I only just wanted to clear up any terminology that I may have used.
HIS HONOUR: I knew what you meant, and I think the lawyers know that there's a requirement, when an accused asks for it, that there be a direction. What do you say Mr Crown, should I give a direction under 164 (sic) concerning the unreliability of Mr - -
CROWN PROSECUTOR: No your Honour.
HIS HONOUR: No, I don't think I should either.
38 It would be a matter for the trial judge in any case to determine whether there was evidence capable of raising a reasonable supposition that a Crown witness was criminally concerned in the events giving rise to the charge. If so, the judge would be required to comply with a party's request under s165(2) to warn the jury about that witness' evidence unless, in the circumstances of the case, there were good reasons not to do so: subs(3). Ordinarily, a judge exercising the discretion under subs(3) should state what those reasons are: R v Beattie (1996) 40 NSWLR 155, per James J at 160. Whether the witness was in fact criminally concerned in the relevant events, of course, would be a matter for the jury to determine. In many cases, that might not be in dispute.
39 In the present case, it would appear from the second exchange with counsel quoted above that his Honour did not consider that there was any evidence which might raise a reasonable supposition that Mr Johnson was criminally involved in the incident. With respect, I do not consider that the matter could be so easily disposed of. In the first place, there was the evidence of Mr Taranto suggesting that Mr Johnson himself was responsible for the shooting. Whatever his Honour might have thought of it, that was evidence for the jury to evaluate.
40 However, the matter does not end there. There was evidence from which it might be inferred that, in any event, Mr Johnson was criminally involved in the affair upon much the same basis as that alleged against Ms Kelly. His own evidence was that, when he first arrived at the appellants' home, he said that something had to be done about the robbery committed at his friend's home and Mr Taranto agreed. It is clear that they set off in search of the perpetrators of the robbery and the theft from the appellants' home and, if they had found them, it seems unlikely that they would have allowed them the benefit of normal legal process. Equally, it is unlikely that much patience or courtesy would have been extended to anyone from whom they sought information about the culprits.
41 Mr Johnson said that he wished only to make enquiries of the complainant and intended her no harm. However, he acknowledged that he was aware that Mr Taranto was armed. It was open to the jury to find that he foresaw that there might be a confrontation with the complainant in which a firearm was used. It is true that, although cross-examination touched on this issue, it was never squarely put to him. Nevertheless, there was sufficient in the evidence fairly to admit of that conclusion.
42 Accordingly, it appears to me that there was material capable of founding a reasonable supposition that Mr Johnson was criminally concerned, on one basis or the other, in the events giving rise to the charges. At the very least, if his Honour thought otherwise, it was incumbent upon him to give reasons for that view.
43 It seems that counsel for Mr Taranto at the trial sought a direction only on the basis of his client's evidence to the effect that it was Mr Johnson who shot the complainant, and he did not argue that Mr Johnson might also have been criminally liable as a participant in a joint criminal enterprise. The fact that he did not do so might be explained by the somewhat peremptory manner in which his Honour dealt with the matter.
44 No direction was sought by counsel for Ms Kelly at the trial, but in an affidavit in this Court he explained that he saw no point in doing so in the light of the fate of his colleague's application. In any event, a request under s165(2) by any party to the proceedings is sufficient to raise the prima facie duty of a trial judge to give a warning.
45 This was an important matter bearing upon the reliability of Mr Johnson's evidence, and one which affected the case of both appellants. In my view, his Honour's failure to give the direction sought, without expressing any adequate reasons for doing so, constitutes a miscarriage of justice necessitating a new trial. That being so, it is unnecessary to determine the other grounds of appeal. However, as there must be a new trial, I think it appropriate to express my view about two matters relating to the admissibility of evidence raised by counsel for Mr Taranto.
