The direction was from Jones v Dunkel (1959) 101 CLR 298. Nothing further of relevance was said in relation to the appellant's failure to call the brother and nephew.
15 The giving of a Jones v Dunkel direction in criminal trials was approved by this court in Buckland (1977) 2 NSWLR 452. The implications in relation to absent witnesses were reviewed by Carruthers AJ in Taufua [1999] NSW CCA 205.
16 It is to be noted that, in Buckland, Street CJ put an important rider on the use of the direction (at 459):
"In criminal proceedings, however, the making of a comment or the indication of the available inference will be attended by a marked degree of caution, inasmuch as in many cases the absence of a witness either for the Crown or the accused might well be explicable upon grounds not readily capable of proof. If it is suspected that there may be some valid reason for a witness not being called, then, in a criminal trial in particular, a careful appraisal is requisite before commenting on the absence of that witness either in address or in the summing up."
17 As occurred in the case of Taufua, the jury received no such assistance in this case. The jury should have been informed, at a minimum, in the present case, that, if the relevant witnesses were in a position to give truthful evidence which would have assisted the appellant, the evidence would necessarily have involved them in having access to premises where a large cache of illicit drugs had been found. They would, accordingly, have been entitled to claim privilege against self-incrimination. The question of a certificate would then have arisen with uncertain outcome. At a minimum, the jury should have been informed of this complication in evaluating whether the appellant should have been expected to call the witnesses.
18 If the direction was to be given, the jury should also have been warned to consider the possibility that, if called, these witnesses might have chosen to lie rather than either to tell the truth or claim privilege in order to deflect suspicion from themselves; and that this would or might occur, if they were called, may have been known to the appellant.
19 That is but one feasible explanation for not calling the absent witnesses in a case such as this. There were other possible explanations. There may have been threats if the accused sought to call the witness, or fear of retaliation if he did. If that was the case the accused may have thought it unwise to disclose the explanation for not calling the witnesses.
20 In such a case as this, if the direction is to be given, the jury would have to be warned, without necessarily being over-specific, that there may be an explanation that has not been disclosed because the accused has reasons for not disclosing it. That is even more so where the absent witnesses are members of the accused's family. One cannot know what under-currents might have come to bear on a decision not to require relatives to testify in such circumstances.
21 In Scott [2000] NSW CCA 187, (2000) 112 A Crim R 543, an appeal was allowed in a case where an unqualified Jones v Dunkel direction was given. The witnesses not called by the accused were alleged by the Crown to be accomplices. Greg James J said (at [34]) as follows:
"To suggest it was open to conclude that the evidence of those persons would not have assisted the case of the appellant was such as to divert the jury. To suggest that they might consider that the appellant should have called those witnesses was entirely wrong. On the Crown case, the witnesses were criminally complicit with the appellant. On the defence case, they, if they were heroin suppliers, had manipulated and deceived the appellant. The Crown's reluctance or inability to call them was not elucidated but the explanation for their absence in the Crown case may have been reasonable. It was not reasonable to suggest that in any way those witnesses should have been called in the appellant's case. The prospect that the jury might, from their absence, think that their evidence might not have assisted the accused's case was, at the least, seriously confusing if not inevitable."
