Application of the "M" principles to this Appeal
52 The Crown case against the appellant was entirely circumstantial. The learned trial judge had given a satisfactory direction to the jury that it could only find the appellant guilty of the charge if the jury were convinced beyond any reasonable doubt that there was no other explanation for the circumstantial matters other than his guilt. His Honour reminded the jury if there were another explanation consistent with the innocence of the appellant, the jury must find him not guilty.
53 As the statement of facts set out above demonstrates, the appellant had provided an explanation for the circumstances which led to him being in the Nissan car on 24 July 1999 when the suitcase containing heroin was found to be in the boot of the vehicle. The explanation, if capable of acceptance, exonerated him from guilty knowledge.
54 Knight v The Queen (1992) 175 CLR 495 was a case where the state of mind of the appellant Knight was necessarily a matter of inference from other facts found by the jury, that is, it could only arise from circumstantial evidence.
55 In a majority judgment Mason CJ and Dawson and Toohey JJ said at p 502:
"In those circumstances the reasoning process which must be employed if the onus of proof beyond reasonable doubt is to remain upon the prosecution is well recognised. As Dixon J said in Martin v Osborne (1936) 55 CLR 367 at 375:
'If an issue is to be proved by circumstantial evidence, facts subsidiary to or connected with the main fact must be established from which the conclusion follows as a rational inference. In the inculpation of an accused person the evidentiary circumstances must bear no other reasonable explanation.'
In Plomp v The Queen (1963) 110 CLR at 243, Dixon CJ cited his previous observation in Martin v Osborne and acknowledged the difficulty found in stating the rule, a difficulty which he said "has not been overcome by employing the expression 'more consistent' as if there could be degrees of consistency". His Honour attempted clarification by citing his further words in Martin v Osborne :
'This means that, according to the common course of human affairs, the degree of probability that the occurrence of the fact proved would be accompanied by the occurrence of the fact to be proved is so high that the contrary cannot reasonably be supposed'.
56 Their Honours continued:
"There are not, as Dixon J observed, degrees of consistency and, if a reasonable jury ought to have found that an inference or hypothesis consistent with innocence was open on the evidence, then it ought to have given the appellant the benefit of the doubt necessarily created by that circumstance."
57 In my opinion, a critical examination of the full detail of the circumstantial evidence, taken with the whole of the evidence in this appeal, leaves me in considerable doubt whether the jury, acting reasonably, could have rejected as a rational inference the possibility that the appellant was in possession of the heroin suitcase albeit without any knowledge as to its contents. This is so notwithstanding the submissions to the contrary made on behalf of the Crown.
58 The thrust of the Crown submission on this point in the appeal is twofold. First, it is said that the circumstantial case was a strong one; and, secondly, recognition must be given to the unique position and function of the jury in being able to see, hear and assess the evidence given by the various witnesses. Reliance in this regard is placed especially on statements in Chidiac v The Queen (1991) 171 CLR 432 at 462; Meissner v The Queen (1995) 59 ALJR 693, and The Queen v Mackenzie in this Court (1995) 82 A Crim R 473 at 500.
59 As to the first argument, I am unable to agree that this was a strong circumstantial case at all. True it is, the appellant was arrested while driving a motor car which was not his own. True it is the vehicle contained a suitcase which had been placed in the boot by a person generally unknown to him, the suitcase itself containing a substantial quantity of heroin. The appellant, however, gave detailed evidence which was corroborated by his wife that he had been contacted by a long time friend from China asking whether he could do a favour by looking after a friend who was coming to Australia as a tourist. He agreed to do this and asked his friend to have the visitor call him. A short time later he received a phone call from a person who identified himself as that visitor and a friend of the appellant's friend in China. This man asked for a favour, namely whether the appellant could pick up a car in the Strathfield area. The appellant did this and was spoken to later in the evening and asked whether, for convenience, the collection of the car could take place the next day. The appellant explained that on the afternoon of the next day he was asked to bring the car into the city. He did so and in due course he made contact with two men, one of whom was the visitor who had rung the night before. On his version, something was placed in the boot of the car while he was in the driver's seat. On the police version, he left the car and opened the boot while a suitcase was put in the boot of the car. In neither version, did the evidence indicate that he had any knowledge of the contents of the suitcase. After the other two had left the car, he was driving the car a short distance to park it near the Silver Spring restaurant in Chinatown when he was arrested. At all times he maintained his innocence.
60 Apart from the general Crown submission that the version of events given by the appellant "defied commonsense" there was only one live issue on credibility. This was the dispute between the evidence given by the appellant and Detective Newton as to whether the appellant had in fact left the car and opened the boot at the time the suitcase was placed in it. Even accepting the Crown version of what happened, this circumstance of itself (or indeed taken with other circumstances in the case) is not capable of excluding a reasonable hypothesis that the appellant was doing no more than extending courtesy to the other man by opening and closing the car boot. It was, in my view, incapable of carrying with it as the only rational inference, the suggested inference that the appellant knew there was heroin or other narcotics in the suitcase. To adopt the phrase in Martin above, the degree of probability that the opening and closing of the boot by the appellant, while he stood at the rear of the car, would be accompanied by the occurrence of the knowledge of the contents of the suitcase could not be "so high that the contrary could not reasonably be supposed."
61 As the learned trial judge said, correctly in my view, to the jury:
"Even if you accept the evidence of Constable Newton on that point, it does not seem to add any weight to the question of the accused's knowledge of the contents."
62 The authorities referred to by the Crown on this aspect of the appeal relate to cases in which there had been not only live, but critical issues of credit involved in the issues before the jury. Chidiac, for example, involved the critical issue of the credibility of the accused's co-conspirators. The statements in these authorities are reminders that it is necessary for this Court to make full allowance for the advantage the jury has, in all cases but particularly where there are such live issues of credit. The present case however, is entirely circumstantial. As I have indicated, the only live issue on credit essentially related to a matter which did not take the circumstantial evidence in any direction so as to be capable of eliminating any inference or hypothesis consistent with the appellant's version of events. Even if the jury thought the appellant had lied on this matter, it does not seem from any material in the appeal papers that the lie, if it were a lie, was relied upon by the Crown as evidence of consciousness of guilt. For that matter, it is almost impossible to see how it could have been so relied upon. Certainly, the judge gave no "Edward's" type direction (see Edwards v The Queen (1993) 178 CLR 193) nor was he asked to give such a direction.
63 I return then to the circumstantial material. It is set out in considerable detail in the Crown's submissions. There were some 66 "circumstances" listed between pp 12 and 17 of the written submissions. The first group of "circumstances" relates to the expenses of the appellant's living, including household and car expenses, the ownership of mobile telephones and a landline telephone service; the fact that the appellant went to a restaurant for a meal; that in the past he had gambled at casinos and that he was at the TAB on the day of the arrest, and that he had travelled overseas. All of these matters were explored in the evidence, that is to say the cross-examination of the appellant and his wife. All were adequately explained. There was no circumstantial material revealed in these matters which was likely to have branded the appellant as a drug importer or courier. Instead, quite a pathetic picture was revealed of a Chinese couple eking out a living in a new country in very difficult circumstances.
64 The next set of "circumstances" was a long litany of matters involved in the arrangements to collect the car, the mobile phone and the meeting between the appellant and the two overseas visitors, Mr Lai and Mr Jin. For example, the list includes the fact that the Nissan vehicle was registered in the name of a person in South Australia; that the appellant did not know the name of the person who owned the vehicle, that he did not know where "Paul" lived or how to contact him after the initial telephone contact had been made with him. He was cross-examined about these matters and his general response was that he saw nothing strange in undertaking this favour for an acquaintance or friend of his own mainland China friend who had asked him to help out.
65 The third series of "circumstances" related to the step by step analysis of the events which occurred on 24 July 1999. These include the circumstances that he travelled into town by himself and did not take his wife (even though she gave evidence that she was three months pregnant at the time); and the appellant gave evidence that, because of her pregnancy, he did not want her to be wandering around or walking around too much. There was also reference to the fact that the appellant had three mobile phones. Both he and his wife were cross-examined about this and explained the circumstances which led to there being multiple mobile phones in their household.
66 The fourth and final set of "circumstances" related to the events which occurred during the brief time after the suitcase was placed in the boot. It is sufficient to say that none of these circumstances of themselves, individually or collectively, point to any knowledge on the part of the appellant in relation to the content of the suitcase.
67 The great majority of the circumstantial material is, in truth, no more than that dissection and restatement of material matters relied upon by the appellant as the innocent explanation for what he did.
68 In my opinion, the inherent weakness in the circumstantial case relied upon by the Crown may best be gleaned from the submission of the Crown in the trial. This was summarised by the learned trial judge in his charge to the jury. This submission was that it comprehensibly defied commonsense that the two men who had the apparent control of the heroin would have left the drug filled suitcase in the rear of the car in the circumstances described by the appellant. The Crown Prosecutor was not able to point to any particular aspect of the evidence which conclusively excluded the possibility of the truth of the explanation the appellant had offered beyond pointing to the position of the two drug carriers and suggesting that, from their point of view, the appellant's story would "defy commonsense".
69 In my opinion, this submission amounts to no more than speculation as to why Mr Jin and Mr Lai would have, or did, make the suspect arrangements. Perhaps they wanted to see whether the police were carrying out surveillance. Perhaps they wanted to test out the appellant's reliability. It may be that they wanted to place him in a compromised situation. All these are possibilities. They are not, however, speculations about the appellant's actions at all, but speculations about the motives and actions of the other two men involved.
70 It seems clear on the evidence the appellant had no connection or communication with the other two men other than as he stated in his own version of events. He was not in a position to see the Mitsubishi parked in the other street; he did not see the suitcase taken from the Mitsubishi. There is no evidence of any conversation between he and the other two men, either before or after the placement of the suitcase in the Nissan which could be relied on to sheet home guilty knowledge. There was nothing in his actions in driving to the Silver Spring Restaurant, or in his reaction to his arrest which betrayed any knowledge of the contents of the suitcase. There was nothing which cast doubt on the prospect that after the two men had their coffee with the appellant, the car (and presumably the suitcase) would be taken away by them.
71 This Court is required, as the decision of the High Court of Australia in M makes clear, to make its own assessment of the evidence, making full allowance for the fact that the jury was the body entrusted with the primary responsibility of determining guilt or innocence. Allowance must also be made for the fact that the jury had the benefit of having seen and heard the various witnesses.
72 Making all those allowances, I do not consider that it was open to the jury to reject as a rational inference the possibility that the appellant, in all the circumstances of this case, did not know that the suitcase contained heroin or narcotic drugs. I accept that some of the circumstances relied upon by the Crown may well have aroused suspicion, perhaps considerable suspicion. Even after a reading of all the evidence, not all of those suspicions are necessarily dispelled. There is, however, a significant difference between unresolved suspicion on the one hand, and satisfaction beyond reasonable doubt on the other.
73 In my opinion, the entirely circumstantial case here lacks probative force in the sense described in Knight supra. It does so in such a way as to lead me to conclude that, even making full allowance for the advantages enjoyed by the jury, there is a significant possibility that an innocent person has been convicted. In those circumstances, this Court is bound to act and set aside the verdict based upon that evidence.
