"Silence in some circumstances amounts to acquiescence and gives consent."
75 These observations were, however, made in the context of the particular facts of the case in which the accused was charged as a principal in the second degree when he refrained from intervening while his wife drowned herself and her children. In the light of the special relationship which existed between them, his acquiescence or silence was properly capable of being understood as encouragement.
76 That there is no general principle by which assent or acquiescence, without more, will give rise to liability can, also, be seen from the decision in Georgianni v The Queen (1985) 156 CLR 473 where Mason J said, at 493:
"In felony at common law the terms "aid" and "abet" are generally used to refer to the conduct of a principal in the second degree, or one who is present at the commission of the offence by the principal offender, while the terms "counsel" or "procure" are generally used in relation to the conduct of an accessory before the fact, or one who is absent at the time of the commission of the offence: 4 Bl Comm 34-36; Ferguson v Weaving [1951] 1 KB 814 at 818-819. In substance, however, there appears to be no distinction between a principal in the second degree and an accessory before the fact beyond the question of presence. In misdemeanour, where no attempt has been made to classify the parties to an offence, each of the four terms is employed to refer to the conduct of a secondary participant. But the terms are descriptive of a single concept. In this regard, I would adopt the observation of Cussen ACJ in Russell [1933] VLR 59 at 67, as being applicable to secondary participation in misdemeanour. Having listed various words, including "aiding" and "abetting" which have been used to refer to the conduct of a principal in the second degree in felony, his Honour observed:
"All the words abovementioned are, I think, instances of one general idea, that the person charged as a principal in the second degree is in some way linked in purpose with the person actually committing the crime, and is by his words or conduct doing something to bring about, or rendering more likely, such commission."
77 Moreover, in Georgianni, the Court made it clear that the principal in the second degree must actually know that the crime is being committed or will be committed.
78 To that extent, the non accidental presence of the appellant and his acquiescence in or assent to what occurred would not be enough, unless it was also made clear that the Crown had to establish that such assent or acquiescence amounted to that degree of encouragement or assistance as would constitute him a principal in the second degree.
79 It would have been preferable for his Honour to have directed the jury in the precise way discussed in Mohan and Clough. It would also have been preferable for attention to have been directed to the mental element of each person who was involved in the shooting, as discussed in McAuliffe, Osland and Georgianni.
80 Of greater importance, however, was the introduction into the oral summing up of the reference to what might be perceived upon "a reasonable view", or what a "reasonable mind" might perceive, as to whether the appellant said or did anything to assent to or to associate himself with the act of the shooter.
81 It may well be that a particular fact or element of a crime may be perceived by a jury as something that upon a reasonable view was present, or as something which a reasonable mind might conclude was present. However, that is not the same as saying that such a matter has been proved beyond a reasonable doubt. Another possibility, even a contradictory possibility, may also be available as a "reasonable view" or as something which a "reasonable mind" could perceive as open.
82 The problem in this regard needs to be considered in the context that this was a circumstantial case in which the jury had to draw inferences. A critical inference, for a conviction of the appellant based upon the second limb, was his non accidental presence as an aider and abettor, in the way explained above. Unless that inference was the only rational inference available, then the proper verdict would have been one of acquittal: Shepherd (1990) 170 CLR 573 and Clarke (1995) 78 A Crim R 226.
83 The oral directions did not deal with this critical aspect. They introduced a test that was inappropriate and that risked diluting the requirement of proof beyond reasonable doubt. His Honour had earlier in his summing up given an instruction to the jury which was correct in law, as to circumstantial proof, and although the written directions did not contain the offending passages, they do need to be regarded as subservient to the specific directions given at this point of the summing up, or at least subject to any qualification introduced thereby.
84 In these circumstances I am of the view that the instructions given concerning the second limb gave rise to an error of law and to a risk of a miscarriage of justice.
85 I am not persuaded that the jury would inevitably have been convicted upon the basis of the first limb of the case, since it was classically a case of the kind considered in Mohan and Clough, in which the Crown could not prove which of Bao and the appellant fired the fatal shots. Particularly was it necessary to turn to the second limb, and to direct the jury with some precision as to what was required to establish the criminal liability of the appellant as a principal in the second degree, since it was his case that he was there as an accidental participant who had no knowledge of what was to occur, who played no intentional part in the shooting, and who provided no encouragement or assistance.
86 The case is not therefore appropriate for an application of the proviso. I would accordingly allow this ground of appeal, quash the conviction and sentence, and order a new trial.
87 McCLELLAN J: I agree with Wood CJ at CL.
88 SMART AJ: The facts and the background are set out in the judgment of Wood CJ at CL with which I agree. I wish to add few comments. One of the problems in the present case was that the Crown appeared to put the prosecution case in slightly different ways.
89 In his opening speech the prosecutor said to the jury (T 16 of 6/3/00):
"In relation to this trial you will have to decide one of two things. You will have to decide whether or not the accused pulled the trigger or whether he was there present knowing that someone - knowing that the gun was going to be fired and knowing that Mr Jin was going to be attacked and he was there available to help him whether or not he fired that bullet …".
90 That was a curious way to open the Crown case. Rightly understood, the Crown case was that both Bao Pham and the appellant were present in the car when the deceased was shot dead. Three shots were fired. Either one of the men fired all three shots or each man fired one or more shots. At least one of the shots killed the deceased. If the jury was not satisfied that the accused fired one of the shots that did not matter so long as they were satisfied that both the men were present, with one or both of them firing the shots and the other aiding and abetting. As Hunt J pointed out in Stokes & Difford (1990) 51 A Crim R 23 at 35, even if the Crown had been unable to establish which one of the two co-offenders was responsible for inflicting the injury it would still have been a classic case of each of them aiding and abetting the other: Mohan [1967] 2 AC 187 at 195. In Mohan the evidence established that the two co-offenders were present and attacked the deceased. The Crown could not say who struck the fatal blow. Hunt J further explained:
"The ratio of that case is that a person who is present, aiding and abetting another in the commission of crime is guilty of that crime as an accessory even in the absence of any pre-arranged plan. That ratio does not depend upon the fact that each of the accused in that particular case was physically attacking the deceased. It would be equally applicable where the finding of aiding and abetting is available from other conduct".
91 It is a pity that the prosecutor did not open the prosecution relying on the principles of Mohan, Stokes & Difford and Clough (1992) 28 NSWLR 396. The judge's attention was not drawn to these authorities and the principle they supported.
92 At the start of his closing speech the prosecutor stated that the Crown case had both a short form and a more complicated form. The short form was that the deceased was murdered by being shot three times. The evidence against the appellant was that he was in the car behind the deceased and in a position to fire the shots. The prosecutor said:
"The only issue is … whether or not when he was sitting in the back seat behind the deceased … he was the one who fired the gun".
93 The prosecutor next referred to the more complex form of the Crown case, contending that it led to the same conclusion of guilt. The prosecutor analysed and discussed the evidence at some length. His address took the best part of a day. In the latter part of his address the prosecutor said:
"On the Crown case, it could very well be that Mr Bao shot the deceased one or more than one times. It's clear from the way the evidence is that he could very well especially have fired the shot into his temple".
94 The prosecutor, after refuting the suggestion that the deceased was the one doing some shooting, contended that the appellant was trying to protect Bao Pham:
"Why is the accused trying to protect Mr Bao here? The only possible reason is because he and Mr Bao were there together. They were there together in relation to shooting the deceased. There is nothing else … open on the evidence. Whether Mr Bao fired all three shots, or whether the accused fired all three shots or whether it was a combination of both of them, it doesn't really make any difference. It doesn't make any difference if the accused didn't fire any shots, or if you are not satisfied beyond reasonable doubt whether he fired any shots. On the evidence its clear they were there together and one of the reasons you can be sure why they were there together … is because the accused is lying about the whole thing".
95 In this passage the prosecutor was adopting or close to adopting the kind of approach envisaged in Mohan, Stokes & Difford and Clough. The matter was not put in those terms in the prosecutor's opening speech.
96 At the end of the prosecutor's closing speech the judge enquired of him whether he wanted the case to go to the jury "on the principal in the first and principal in the second". The prosecutor replied, "I do".
97 In his closing speech counsel for the appellant contended that the Crown was having a two-way bet (T689). However counsel revealed his understanding of the Crown case, stating (T689):
"[The prosecutor] said you will have to decide one of two things: Whether … the accused pulled the trigger or whether … he was present there and knowing that the gun was going to be fired and knowing that Mr Jin was going to be attacked and he was there available to help [Bao], whether or not he fired that bullet or not".
98 Counsel for the appellant also made a lengthy closing speech canvassing the facts in much detail. Upon the conclusion of that speech, the judge (at T728) told counsel how he proposed to instruct the jury on the first approach by the Crown, namely, that the accused fired some one or more of the three gunshots. The judge next explained how he proposed to instruct the jury on the Crown's second approach. That was in terms of his written directions as set out in the reasons of the Chief Judge.
99 The prosecutor asked the judge to tell the jury additionally on the second approach that if they were not sure whether the deceased fired one of the shots they did not have to find that the other person fired all the shots. They could still convict the accused.
