· Eleven intercepted phone calls in the two weeks preceding the transaction between the Appellant and Le.
· Call charge records showing two phone calls from Le's phone to the Appellant's phone made minutes before Le left St Albans in Victoria on Monday 1 May 2000.
· Call charge record showing a phone call made from Le's phone to the Appellant's phone about eight minutes before Le's car arrived at McDonalds on Parramatta Road at Camperdown/Stanmore.
· Surveillance both electronic and visual of the car as it drove from McDonalds to William Street, Leichhardt.
· Call charge record showing a phone call made from Le's phone to the Appellant's phone about thirty seconds before Le's car was in the vicinity of the Appellant's house.
· Visual surveillance of Le's car on William Street near to a lane running behind the Appellant's house situated in James Street, off William Street.
· Electronic surveillance (tracking device on Le's car) showing that it was stationary between 4.07 and 4.19am positioned in the vicinity of the Appellant's residence.
· Visual surveillance of Le's car leaving William Street and travelling south, out of Sydney.
· Search of Le's car revealing 5.95 kilograms of heroin inside the rear left passenger door worth about $726,000 to $770,000.
· Location of a piece of paper in the Appellant's handwriting in the Appellant's house, when searched around 10.30am on the morning of 2 May 2000, on which the Appellant had written "Phuong $748,000".
· Location of a large amount of cash, namely $780,720 in the Appellant's house corresponding approximately with the value of the heroin seized from Le, much of the money being in new notes.
· The Appellant's claim that the money was the proceeds of savings over the years was inconsistent with tax records of his employment and businesses.
· $55,000 of the cash was wrapped in Melbourne Crown Casino wrappers dated 7 April 2000 to 1 May 2000.
· Call records and admissions established the Appellant was in Sydney, not Melbourne, on 1 May 2000.
· Surveillance of Le acquiring cash at the Melbourne Crown Casino on 29 April and 30 April 2000.
· A search of the Appellant's garage accessible from the back lane was found to be big enough for two vehicles.
12 The central issue in the case was whether an act of supply had occurred on 2 May at the Appellant's residence. The Crown case was circumstantial. The case was based in part on the fact that Le had driven from Melbourne to the immediate vicinity of the Appellant's residence in Sydney. It was obviously important for the Crown to establish that it was overwhelmingly probable that Le had entered the Appellant's house. The fact that they knew each other, and the extent and nature of their association, was a matter which was relevant to this issue and, therefore, to the issue of supply.
13 In my opinion, his Honour was correct in his conclusion that the evidence on the tapes did go to the issue of supply of heroin. The fact that the two individuals had numerous conversations with each other over the weeks immediately preceding the occasion of the alleged supply is relevant to whether or not Le called at the residence on that date. However, the content of such conversations may also be relevant to whether or not the event occurred.
14 The frequency and nature of the contacts by telephone were of direct relevance. Admissions as to participation in other drug dealings were plainly prejudicial. Nevertheless they constituted an appropriate addition to the Crown circumstantial case.
15 Admissibility can be justified on two bases. First, a narrow basis that the evidence of the conversation of 29 April was admissible as possibly referring to a drug supply to occur within a few days and earlier conversations establishing the true nature and content of that conversation. Alternatively, the earlier conversations were admissible on a broader basis identified in Harriman v The Queen (1989) 167 CLR 590, that the prior relationship of other drug dealings was such that no innocent explanation of Le's trip from Melbourne to the vicinity of the Appellant's residence was open.
16 The content of the last conversation is capable of being understood, with an explanation of the argot of the drug trade, as referring to a future supply. That conversation was as follows:
"PH: PHONG (LE TAN PHONG)
G: GIA (QUACH TAN GIA aka NAM)
G Hello,
PH Is that you? And my wife where is she? I couldn't call her and didn't see her coming down either.
G Oh, don't you know? Just ate in the morning with my wife and I though.
PH You mean this morning?
G Yeah, yeah
PH Could you… could you … I couldn't get through to her number and could you phone her for me and tell her to call me, please.
G Yes, what's wrong, anything serious?
PH Just that I got some papers ad I tell her to come down now to 'ay' with me, got … got … three 'dong' though … papers.
G Ah … oh … Is that so? … oh.
PH Yesterday when you've just left and I then got three 'dong', so fuckin' bad luck.
G Should have fuckin' left it a bit later yesterday eh?
PH How can you tell? You know what I mean?
G Yeah, so how many 'dong' are left? -
PH Three 'dong' left.
G No, now that how many …
PH (overtalking) Three 'dong' like that.
G of the other thing are left.
PH The other thing, three remains, three.
G Three, big or small?
PH Big.
G Big eh? Yeah.
PH Yesterday afternoon my friend just returned and borrowed three.
G Oh, yeah, yeah, so when … about to have a meal?
PH Here, that's what I call my wife down for!
G Yeah, but how come I heard that she doesn't do anymore?
PH Oh don't you listen to this woman.
G That's why fuckin' she was saying in the car, …
PH Just forget about her, don't listen to her.
G I know, but I want to know, so I'd leave stuff for you … do you understand?
PH (overtalking) I do, I do, whichever, whichever the case I have to tell you first but.
G Yeah, because all of a sudden she said like that in the car but don't tell her I told you alright? And she would get back at me, and I said how come, PHONG had told me like that and now you say differently.
PH Mm
G She … she said … whatever she said … I don't even know …
PH No, don't worry, this woman changes her mind just like that. Now could you please … please call her to tell her to call me.
G Yeah, yeah okay bye."
17 As explained by Detective Nguyen, who had experience as a translator and investigator with the Drug Crimes Unit, elements of this conversation are capable of constituting an announcement by Le that he had in his possession an identified quantity of money ("I got some papers" and "I then got three dong") and by the Appellant that he had possession of heroin ("So I'd leave stuff for you"). It was open to the jury to conclude that this conversation - especially "I'd leave stuff for you" - was a reference to a transaction that had not yet occurred. On that basis the conversation was capable of constituting a preparatory step for the events of 2 May.
18 The conversation of 29 April, like the other conversations on the tapes, is virtually incomprehensible. It could, at least theoretically, be explained on the basis that the parties to the conversation spoke in a form of shorthand derived from considerable familiarity with each other. The contents of the earlier conversations do counteract any such conclusion. Furthermore, some of the code words used on 29 April - "stuff" as heroin and "dong" as a quantity - had appeared in earlier conversations.
19 The earlier conversations are, accordingly, relevant to a proper understanding of the conversation of 29 April. The fact that these two individuals had regular conversations of an incomprehensible character and in code, with the use of terminology, identified by a person able to give opinion evidence, which reflected the argot of the drug trade, does significantly reinforce the inference that the conversation of 29 April was in code and that that code was identifiably associated with dealings with drugs. (See R v Chan [2002] NSWCCA 217 at [47].)
20 The evidence of Detective Nguyen was essentially in a narrow compass, although it does appear that he was permitted to stray beyond his area of expertise on occasions and was permitted to adopt an advocacy stance. He accepted in cross-examination that there was no express reference to 2 May in any conversation. He also accepted that the references were to past transactions. His evidence was directed to explaining what might otherwise be incomprehensible. His particular interpretation, of course, did not have to be accepted by the jury. His evidence did not, in any event, delineate the permissible use of the taped conversations as part of the Crown's circumstantial case.
21 It appears that the Crown did submit that a number of the earlier conversations were in some way linked to a large future delivery. His Honour referred to the Crown's submissions in this way in his judgment rejecting the application for an acquittal by direction and in his summing-up. It is difficult to see how this submission could be sustained from a perusal of the transcripts, even as explained by Detective Nguyen. However, that was a matter for the jury.
22 The alternative basis for the admissibility of the taped conversations is the High Court's decision in Harriman. That was not a case under the Evidence Act 1995, but it did involve the admissibility of evidence of prior drug dealings. Mr P Byrne SC who appeared for the Appellant with Mr A Bellanto QC submitted that the case of Harriman was distinguishable on the basis that it involved the admission of evidence for what would now be described as a "tendency" purpose. It was submitted that the judgments in Harriman employed tendency reasoning.
23 In Harriman the accused and his co-offender, Martin, had travelled to Thailand together. The co-offender had then travelled abroad and posted heroin to various addresses in Australia. Evidence was admitted of prior involvement between Harriman and Martin in the sale of heroin.
24 In my opinion the Appellant's submissions in this respect should be rejected. The reasoning in Harriman is consistent with the admissibility of evidence of prior heroin dealings on a basis other than tendency reasoning. In Harriman, it was admitted that there was in fact a meeting between Harriman and his co-offender Martin and the issue was to determine the events that occurred at that meeting. The same is true in this case, albeit the fact of the meeting is not admitted.
25 Brennan J identified the principle he would apply at 594 in a way which clearly distinguished between tendency reasoning and other uses:
"However, where evidence does show more than the mere commission of another offence or predisposition to commit an offence and is otherwise probative of the offence charged or of a fact in issue, there is no rule of evidence which compels its exclusion. If, as a matter of human experience, the evidence tends to establish the offence charged or a fact in issue otherwise than by showing merely the commission of another offence or a propensity to commit an offence , the evidence is admissible. I would therefore respectfully agree with McHugh J that evidence of events which are part of the res gestae is admissible - and will usually be admitted - even if that evidence reveals the commission of an offence other than the offence charged." [Emphasis added]
26 With respect to the particular aspects of drug dealing in issue in the proceedings, his Honour concluded at 595-6:
"Evidence of prior involvement by Harriman and Martin in the sale of heroin in association, evidence (from the witness Lisk) of prior sales of heroin by Harriman and evidence of Harriman's use of heroin were clearly prejudicial and were not admissible unless something more than the commission of prior offences was thereby revealed . In my opinion, more was revealed . The concatenation of these pieces of evidence showed that Harriman, prior to April 1987, had participated repeatedly in one role or another in heroin dealing in Western Australia. He had participated in a trade notorious for its clandestine organization, the creation of distribution networks of dealer-users, the payment of large sums of money enforced (if need be) by vicious measures, and the urgent demand by addicts for sources of supply. A person who is shown to have participated to a substantial degree in that trade - I am not speaking of mere use or of an isolated sale - is likely to have incentives to continue his participation in the trade and, because of the nature of the trade, is more likely to have done so than one who has not been a substantial participant. Evidence of substantial participation in the heroin trade can support an inference of continued participation although, of course, each case depends on its own facts. In determining whether or not evidence of participation can support such an inference regard must be had to the extent and duration of past participation, the proximity in time between the past participation and the offence charged and the whole of the circumstances of the case. In this case, the extent of Harriman's participation was such that, in the absence of anything to suggest that the participation by Harriman and Martin in the sale of heroin in Western Australia had been discontinued, the guilty inference might properly have been drawn.
Evidence of Harriman's participation in the heroin trade not only strengthened the Crown's allegation of motive; it tended to make it more likely that Harriman's relevant contacts with Martin - providing Martin with his (Harriman's) address in Bangkok and arranging to meet there, the visit to Chiang Mai, the furnishing of addresses in Western Australia - were for a guilty rather than an innocent purpose : see Plomp v The Queen (1963) 110 CLR 234. That evidence was highly probative of the offences charged. It was admissible, whether or not Harriman had raised in cross-examination the 'defence' that Martin was acting alone. There was no ground for excluding it in the exercise of a discretion." [Emphasis added]
27 So in this case it can be concluded that the evidence of the contact between the Appellant and Le occasioned by Le driving from Melbourne to the immediate vicinity of the Appellant's house could be said to be, to use Brennan J's phrase, "for a guilty rather than an innocent purpose".
28 The issue is whether the use to which Brennan J held that prior drug dealings could be put is within the distinct formulation of the "tendency rule" in s97, a rule which is derived from, but is not necessarily co-extensive with, the common law (Papakosmos v The Queen (1999) 196 CLR 297)
29 Are the prior drug dealings "conduct" admissible "to prove" that the Appellant "had a tendency" to, relevantly, engage in the supply of heroin? The crucial words are "to prove".
30 As s95 makes clear, evidence may be admitted if it is relevant for another purpose without passing the special test of the balance between probative value and prejudicial effects. Sections 97 and 98 identify distinct kinds of evidence and, apply to them a higher order of test, namely significant probative value. In criminal cases where such evidence is sought to be adduced by the prosecution, s101(2) imposes a more stringent requirement for the balancing exercise, i.e. requiring the probative value to "substantially outweigh" any prejudicial effect. The lower order tests in s135 and s137 of the Act do, however, apply to evidence admitted for a purpose other than a tendency or coincidence purpose.
31 Although the word "tendency" is not defined, the significance of the words "to prove" is emphasised by the definition of "tendency evidence", which is the relevant formulation in s101. Those words are defined to mean "tendency evidence means evidence of a kind referred to in subsection 97(1) that a party seeks to have adduced for the purpose referred to in that subsection" [Emphasis added]. ("Coincidence evidence" is defined in, relevantly, the same way.)
32 The focus is on the purpose of the tender. Section 97 is irrelevant where evidence is admitted for a purpose other than to show tendency. (See R v AH (1997) 42 NSWLR 702 at 708.)
33 Brennan J's reasoning uses the language of the common law in distinguishing "predisposition" from evidence "otherwise probative" of the offence. The same kind of distinction exists under the Evidence Act 1995 between evidence "to prove … a tendency" and evidence "to prove", relevantly, whether Le entered the Respondent's house and/or the character of the transaction that occurred on that occasion.
34 Toohey J also regarded the evidence in Harriman as relevant on a basis other than propensity. His Honour said at 609:
"… it was part of the Crown case that the two men acted in concert and the defence case that they did not. Evidence of a transaction, shortly before, involving the sale of heroin to Gawthorpe and in which the two men had been concerned was relevant to the likelihood of the applicant having acted in concert with Martin when the two men were in Thailand together and when one of them (Martin) had obtained heroin, taken it to London and then sent it to Western Australia.
Now it is true that such evidence was also likely to demonstrate a propensity on the part of the applicant to engage in heroin trafficking. But the evidence went beyond that . It was relevant to the character of the association between the applicant and Martin and was admissible for that reason, though, questions of prejudice aside, possible misuse of the evidence by the jury required that its purpose be explained with some care to them … It was the relevance of the evidence to the likelihood that the two men acted in concert in Thailand that made it admissible. There was some prejudice in the notion that the applicant was likely to have been involved with Martin in the importation of heroin because the two had been involved in the sale of heroin a short time earlier. However, it is hard to see any proper basis on which the evidence should have been excluded. Its probative force was strong and clearly outweighed its prejudicial effect when the defence was that Martin was acting independently of the applicant." [Emphasis added]
35 In this case, the prior drug dealings were, to use Toohey J's phrase "relevant to the character of the association" between Le and the Appellant. That association is relevant to determining both the probability of and/or the nature of a meeting on 2 May. It was not admitted "to prove" that the Appellant had a tendency to engage in the supply of heroin.
36 Gaudron J posed the matter in a similar way at 613:
"Evidence which shows no more than the propensity of an accused to engage in criminal conduct of a particular kind or that the accused is the sort of person likely to commit the offence charged is not admissible to prove that he committed the offence charged … However, evidence which has a high probative value and raises as a matter of common sense and experience , the improbability of the offence charged having been committed other than as claimed by the prosecution is admissible in a criminal trial, notwithstanding that it discloses prior criminal conduct or propensity to commit the offence." [Emphasis added]
37 Her Honour said at 613-614:
"It was open to the prosecution to negate the possibility that Martin had acted independently of the applicant by evidence which, as a matter of common sense and experience , rendered that improbable . Evidence to that effect, if it disclosed prior criminal activity on the part of the accused, would only be admissible if of high probative value." [Emphasis added]
38 Her Honour concluded at 614-615:
"The undisputed evidence that Martin and the applicant were business associates and had travelled together to Chiang Mai gave rise to an inference that the journey had been undertaken for a common purpose. The applicant said the purpose was solely recreational; Martin said it was to obtain the heroin later posted by him to Australia. The evidence that the applicant had supplied heroin in Western Australia to the witness, Gareth David Lisk, that he had on one occasion collected $20,000 as payment for heroin supplied by Martin to the witness Gawthorpe, and that he had paid money to Gawthorpe for delivering heroin from Martin to Lisk, when taken in conjunction with the other evidence in the case (but leaving aside Martin's evidence as to the obtaining of the heroin and the applicant's involvement in that venture), allowed for the admeasuring of the probability that the purpose was as identified by Martin and the improbability of the purpose ascribed by the applicant. And on those issues, if accepted by the jury, it had a high level of probative value. When taken with the other evidence in the case (again leaving aside the evidence of Martin as to the obtaining of the heroin and the applicant's involvement in that venture), as a matter of common sense and experience, it pointed inextricably to the long and uncomfortable overnight journey to Chiang Mai having been jointly undertaken for the purpose identified by Martin.
The evidence of the applicant's dealings in heroin in Western Australia was properly admitted notwithstanding that it revealed past criminal activities on his part." [Emphasis added]
39 Similarly in this case, "as a matter of common sense and experience", to use Gaudron J's phrase, the prior drug dealings raise the improbability that there was no meeting and/or no meeting relating to drugs, on 2 May. The evidence was not admitted "to prove" a "tendency".
40 McHugh J said at 627:
"Upon the trial of a criminal charge, evidence proving that the accused had been guilty of other criminal acts is not admissible if it does no more than prove that the accused has a general criminal disposition which makes it likely that he committed the offence with which he is charged." [Emphasis added]
