…….[The respondent] can complain that the police elicited evidence that they could not obtain lawfully in an ERISP procedure and the court may consider that the probative value of such evidence is outweighed by unfair prejudice to the accused.
124 Insofar as it appears to me that his Honour may have determined that the evidence was unfairly prejudicial to the accused, either as a distinct ruling or as a consideration relevant to some other discretion, his Honour's decision to reject the evidence cannot stand.
Did the police conduct produce unfairness?
125 Although it should be evident by now that I would allow the appeal and quash the order made by Shaw J, I believe I should say something about what is the crucial issue in this matter, notwithstanding that it may be necessary for a judge to consider the issue afresh. It was fully argued by the parties on the hearing of the appeal and I have formed a firm view about it.
126 Understandably, considerable reliance has been place by counsel for the respondent on his Honour's finding that the police knew that the respondent would probably not have made any admissions, if he had known that the second conversation was being recorded. It was submitted that this fact, together with the other matters listed in paragraph [81] of his judgment, set out above, justified his Honour in finding that it would be unfair to admit the second conversation.
127 In my opinion it is too simplistic to reason that, because the respondent may not have made admissions had he known his conversation was being recorded, it was unfair to use the admissions against him. The fact that the respondent was tricked into believing that the conversation was not being recorded might enliven the discretion to reject the evidence, but in my view a relevant factor in deciding whether it would be unfair to admit the evidence is the reason why the respondent would not have spoken had he known the true situation. This is a matter touched on by Shaw J and those arguing the matter before him, but was not apparently examined in any depth.
128 As his Honour accepted in paragraph [80] of his judgment set out above, it was not unfair to admit the evidence simply because it was being surreptitiously recorded by police. Nor, in my view, was it necessarily unfair to admit the conversation simply because the respondent would not have spoken had he known that his conversation was being recorded. For example, if his objection to the police recording the conversation was that he did not want the police to have a reliable record of what he was prepared to say to them, I find it difficult to understand how it would be unfair to the respondent to have admitted against him a reliable account of what he freely and voluntarily said to the police.
129 I would see nothing improper, for example, in the police covertly recording an interview with a suspect at a police station, where the suspect was prepared to answer questions but refused to have the interview electronically recorded. In such a situation it would not be unfair to an accused to admit the evidence of the recording, even though, if the suspect had known of the recording, he would not have answered the police questions. It would be less unfair than if the Crown were to lead evidence of the conversation based upon a record made by police some time after the conversation from their memory of what was said during it.
130 It is on the issue of what the accused was led to believe by the police on 15 May that the first conversation assumes some importance. From the passages of that conversation, which I have set out earlier in this judgment, it is apparent that the respondent was generally prepared to answer questions about the Kress robbery provided that what he said was not recorded in any way. The only reason he gave for not wanting his answers recorded was that he did not want to "look like a dickhead". He had been informed on at least two occasions that what he said might be recorded and might be used in evidence at court.
131 From what the respondent is heard to say as a result of the use of a listening device in the Bass Hill premises and referred to in paragraph [28] above, it appears that the respondent thought that what he had said to the police was "off the record"; that is in contradistinction to "the confessions" that the police wanted. If this statement is taken to mean that the respondent believed that what he had said to the police in the first conversation would not be used as evidence against him, there was nothing that the police had said or done to induce that belief. In any event, so far as the investigating police were concerned, that belief was well justified. According to their evidence on the voir dire, Detectives Abdy and McLean did not believe that his statements would be admitted into evidence because they were not electronically recorded and that was the reason that they did not arrest him for the Kress robbery on 24 April.
132 It may also have been the fact that on 15 May the respondent believed that anything he said to the police was "off the record" and could not be used as evidence against him because he understood it was not being recorded. But if that were his belief, again the police had, at least at the commencement of the conversation, done nothing intentionally or recklessly to induce it. At worst, they simply tricked the respondent into believing that they were not recording the conversation.
133 In my opinion there is a very significant difference, for the purposes of the admission of evidence of confessional statements, between, on the one hand, subterfuge by the police which is aimed merely at inducing a suspect to believe that what he said to them was not being recorded, and, on the other hand, subterfuge which is aimed at inducing in a suspect the belief that what he said would not be used in evidence against him. I do not believe that conduct of the first type necessarily requires that the admissions obtained as a result of the subterfuge be rejected under s 90 or otherwise. On the other hand conduct of the second type would clearly enliven the discretion to reject the evidence under s 90 and it may be the case that, generally speaking, any admission resulting from such a representation would be rejected in the exercise of discretion.
134 In the present case I do not believe that there was any evidence before Shaw J from which it could be inferred that, before the commencement of the second conversation, the police set out to cause the respondent to believe that anything said to them by him would be "off the record" and would not, therefore, be used in evidence against him. Subject to any finding of other relevant misconduct by the police during the course of the interview, I am of the opinion that it would not be unfair to admit evidence of the second conversation simply because the police had tricked the respondent into believing that they were not recording what he was saying to them, and, therefore, to speak when he otherwise would not have done so.
135 However, it may be that at a point in the conversation, when the respondent was being reticent in supplying the information that the police were attempting to obtain, the police did at least attempt to induce in the respondent a belief that what was being said would remain between the three of them and would not be used in evidence against him. That point may have arisen during that part of the conversation set out in paragraph [38] above, and in particular when Detective Abdy said:
