26 On the other hand, there are cases where, in light of the evidence and the issues, a Domican warning would be unnecessary, and indeed counterproductive, in respect of evidence which might be described as "recognition" evidence. In R v Matteo,[19] the three witnesses who identified the accused were thoroughly familiar with him. The issue at trial was not whether they might have been mistaken in their identification, but rather whether they were telling deliberate lies. In those circumstances the Court of Appeal held that the trial judge was correct in not giving a Domican warning to the jury. Such a direction would have run counter to, and undermined, the case made by the accused at his trial.[20]
27 In R v Spero[21] the issue was whether it was the accused who had assaulted and raped the elderly complainant. The accused was well known to the complainant. At the time of the assault the complainant had a substantial opportunity to accurately observe the person who she said was the accused. Accordingly the Court of Appeal held that it was not necessary for the trial judge to have given the jury a Domican ruling.[22] In Smith v. Western Australia,[23] the issue was also whether it was the accused who had, some years earlier, indecently assaulted the complainant. The incidents were said to have occurred at the home of two witnesses, Mr and Mrs DC. They both knew the accused reasonably well and gave evidence that it was the accused who had, from time to time, stayed overnight at their home. They identified the accused from a photoboard shown to them by the investigating police. However, the issue at trial was not whether Mr and Mrs DC had falsely identified the accused as the person who stayed overnight at their home on a number of occasions. Rather the issue was whether the person, so identified, had been at their house and stayed overnight on the occasion when the offences were said to have been committed. For that reason the Court of Criminal Appeal of Western Australia held that the trial judge did not err in declining to give a Domican warning to the jury.[24]
28 The effect of the authorities to which I have referred is that an appropriate warning may need to be given to the jury where, on the facts of the case, a real issue is raised as to the reliability of one or more of the processes of observation, recognition, memory or recall, involved in the evidence of a witness claiming to have recognised the accused as the person observed by the witness on the occasion in question. The question whether such a warning is required depends on the particular circumstances of the case and on the precise issues which arise concerning the "recognition" evidence. In both Boardman and Carr, each witness had some previous familiarity with the accused person at the time the witness observed the person identified by him or her as the accused. In each case the witness had a reasonable opportunity to observe the person who the witness said was the accused. Nevertheless, in each case, the court held that a specific warning should have been given to the jury as to the dangers in the evidence of the witness that it was the accused who had been observed and recognised by him or her on the relevant occasion. In both cases, it seems, the courts perceived the potential for error at two stages of the relevant witness' cognitive processes. First, in each case, there was some potential for error in the recognition by the witness of the accused, in light of the witness' limited previous acquaintance with the accused, and in light of the potential for other circumstances to have then wrongly suggested to the witness that the person observed was the accused. Secondly, in both cases, there was seen to be a potential for error in the later recollection by the witness that he or she had indeed recognised the accused as the person observed on the relevant occasion.[25] In Boardman, Winneke CJ was concerned that the identification parade may have led the witness to have identified the accused not so much as the person who robbed him, but as a person who he saw three days before the robbery. In Carr, the lengthy intervening period may have distorted the recollection of the witness that it was the accused who she saw in the company of Paget (the accomplice) shortly after the commission of the robbery.
29 In the present case the factors which weigh in favour of giving a Domican direction to the jury are not as cogent as they were in either Boardman or Carr. It is not suggested that, in 1999, Lai was mistaken in then recognising the two police who made the alleged corrupt approach to him. On the evidence in the trial, such an error would be highly improbable. However, Mr Young did clearly put in issue the question whether Lai was mistaken in recollecting in 2003, and in his evidence, that Cox was one of the two Drug Squad members who made the corrupt approach to him in 1999. Lai did not know Cox previously. He agreed, in cross-examination, that he recalled Cox and Sadler as a duo who generally worked together. He was not required to recall the identity of the persons who made the corrupt approach to him until four years after the event, when he was interviewed by members of the Ceja Taskforce in 2003. According to his evidence (which is denied by Detective Sergeant O'Neill), it was then suggested to him that, according to the records, the only members of the Drug Squad with whom he had been in contact were Cox and Sadler. The Ceja investigators did not show any photographs to Lai from which he might identify the two police members who he alleged made the corrupt approach to him in 1999.
30 In these circumstances there was, in my view, some scope for error in the recollection of Lai as to the identity of the members of the Drug Squad who he alleged made a corrupt approach to him in 1999. He had limited familiarity with Cox. He was then a frequent user of heroin. He was not required to recall the identities of the two relevant policemen for some period of time. According to Lai, when he turned his mind to that matter, it was in circumstances which might have influenced him to recall, incorrectly, that Cox was one of the two police who made the corrupt approach to him. In those circumstances, given that the issue has been squarely raised by Mr Young, and given that it is conceivable, on the evidence, that an error might have been made by Lai in his processes of recalling one identity of who made the corrupt approach to him, I consider it necessary that I give to the jury a direction in relation to the matters which I have just referred to, in line with the principles referred to in R v Domican.
31 Mr Young submitted to me that the warning which I give to the jury on this issue should not be extensive. I intend to inform the jury that the warning is only relevant if they otherwise accept Lai's evidence as truthful. I shall inform the jury of the general experience of the law of the potential for error which occurs with identification evidence, including evidence of the type under consideration in this case. I shall direct the jury that they should therefore take particular care before accepting the evidence of Lai that he accurately recalls that it was Cox who was one of the two persons who made the alleged corrupt approach to him in 1999. I shall draw to the attention of the jury the matter to which I have referred in the previous two paragraphs of this ruling.
Lai - propensity direction
32 For the purpose of completeness I note that, in my final directions to the jury, I shall also give a "propensity" direction in relation to the evidence of Lai. The evidence of Lai is relevant to the issues in this case because, on the Crown case, the corrupt approach to Lai marked the beginning of the conspiracy alleged in the presentment. In his opening, Mr Tovey QC made it clear to the jury that the Crown would not contend that either of the accused men should be convicted on the evidence of Kenneth Lai. The Crown accepts that the accused could only be convicted if the jury were satisfied beyond reasonable doubt as to the evidence of Duy Le. In my directions to the jury I intend to remind them of the role which Lai's evidence plays in the Crown case. I shall also direct the jury that, if they accept Lai's evidence, they must not reason that, by reason of that evidence, the accused were the kind of people who were likely to have acted in the manner alleged by the Crown.[26]
Corroboration
33 It is common ground between the parties that there is no evidence, independent of the testimony, of Kenneth Lai, capable of corroborating Lai's testimony. Accordingly I shall direct the jury to that effect.
34 In the course of submissions Mr Tovey QC has outlined to me, in general form, the evidence which he submits is capable of corroborating the testimony of Duy Le and Loan Tran. However in the course of discussion with counsel it became clear that I shall be unable to rule on the question of what evidence is capable of corroborating the testimony of those two witnesses until the conclusion, at the least, of Mr Tovey's final address. A significant component of the evidence which the Crown submits corroborates those two witnesses consists of some components of the various event charts and other charts which have been tendered in evidence before the jury. Counsel have all agreed that it will be better to defer any further submission and ruling on this issue until Mr Tovey has made his final address, in which he intends to identify to the jury the specific parts of the charts and the like upon which he intends to rely against each accused. It may also be necessary for me to defer ruling on the matter until the conclusion of defence counsel's final address, since Mr Young has foreshadowed a submission that some of the evidence which he apprehends the Crown will rely on is "intractably neutral".
Conclusion
35 I summarise the conclusions which I have reached in this ruling as follows:
