The trial Judge's decision
111I turn then to his Honour's findings. It is convenient, I think, to go directly to the conclusions expressed at Appeal book 121-122. These occur on page 70 of his Honour's reasons. He said:
[227] I am satisfied and determine that the evidence identified and particularised in Table A in the Coincidence Notice is evidence that is capable of rationally affecting the probability of the existence of the following facts in issue:
(1) Possession of [DSJ] of inside information.
(2) That that information was communicated by him to [NS].
(3) That he procured [NS] to acquire Division 3 financial products.
(4) That [NS], whilst in possession of inside information, acquired Division 3 financial products.
[228] For the purpose of determining admissibility, I am satisfied and determine, in light of the evidence which the Crown proposes to adduce that, in accordance with the test to be applied, the jury would be likely to assign that evidence significant probative value within the meaning of s 98(1)(b).
[229] The probative value of the evidence referred to in [228], I assess as being high based upon the following matters:
(1) The similar events identified and particularised in the Coincidence Notice.
(2) The sequence and timing of the specified events before and following the acquisitions the subject of the counts in the indictment.
(3) The number of the events and the attenuated similarity of such events. A pattern of events may still exist on the basis of similarities even though a variation in the pattern may occur in some aspects (as in the case of GasNet).
(4) The capacity of the evidence in relation to such evidence to rationally affect the probability of the existence of facts in issue including, in particular, the issue of "possession" and procurement within s 1043A(1)(d).
(5) The capacity of the evidence in question to establish a relevant interrelationship between the issues of possession of inside information, communications between [DSJ] and [NS], the transfer of such information from one to the other, the issue of procurement by [DSJ] and arrangements for the acquisition of the relevant financial products and the acquisitions themselves.
(6) The evidence establishing that, in relation to all acquisitions in entities referred to in the counts in the indictment, Moody's had previously been entrusted with inside information by and in relation to all such entities.
112These conclusions were principally in connection with the application of s 101, but they referred back to and gave content to his Honour's earlier findings on significant probative value. After an extensive series of deliberations on the issue of significant probative value his Honour, prior to examining Mr Odgers' submissions, had earlier said at Appeal book 114:
[195] Accepting the Crown's evidence as I must for the purpose of determining the issue of significant probative value, I have concluded that the "events" " and their surrounding circumstances do exhibit similarities and for the purposes of determining admissibility under s 98, I consider they constitute striking similarities. In assessing the probative value of the evidence in question, it is relevant to take into account the facts relied upon in the Crown case in relation to each count that are, at least, consistent with what might be termed selectivity in the acquisitions in the sense that those acquisitions ... related to entities that had provided to Moody's what became inside information.
113His Honour then turned to Mr Odgers' submissions. First, he rejected Mr Odgers' primary submission relating to the process of finding relevance in s 55. Secondly, in relation to the broader submissions made by Mr Odgers as to the interpretation of s 98, his Honour said:
[205] In relation to the submission that under s 98 more is required than that an inference is " open " on the evidence for a finding in respect of "significant probative value" , I respectfully agree. I have proceeded on that basis. An assessment under that provision is directed to evaluating the strength of the evidence including inferences based on an acceptance of the evidence in question.
[206] I, with respect, do not accept the submission that the requirement under s 98(1)(b) means " ... the Court must evaluate whether it could rationally be concluded that the probability of the inference the Crown seeks to draw is significantly greater than the probability of an inference inconsistent with that fact" ... In that respect, I refer to what has been said on that issue above. However, in my assessment, for the purposes of determining admissibility under s 98(1)(b), I consider that the "probative value" of the evidence relied upon by the Crown in relation to the charged matters is such that, assuming a jury accepted that evidence at trial, then, on that basis, the jury would be likely to assign the evidence significant probative value such as to render the inferences relied upon by the Crown as having a high degree of probability. It need hardly be said that that is not intended to be the expression by me of any final opinion as to what or how a jury should decide. A jury's actual assessment will depend, of course, upon its acceptance of the evidence in the Crown case following cross examination and in light of all the evidence in the case.
114These conclusions, forcefully stated as they were by the trial Judge, do not, however, clearly indicate whether his Honour had rejected the Crown submission that, in performing the task ascribed by s 98, he must eschew altogether the recognition of any alternative explanation inconsistent with guilt arising from the Crown evidence. Mr McHugh and Mr Odgers placed reliance, however, on his Honour's remarks at paragraph 64 (Appeal book 75) where his Honour had said, in the context of a discussion on "significant probative value":
The Appendix to this judgment contains a summary of facts and particular matters that were raised in the submissions for [DSJ] and in the Crown's reply. For reasons discussed below, I have concluded that there is no requirement for the purpose of a ruling on admissibility under s 98 to determine the existence and weight to be given to inferences that may be considered as alternative or inconsistent with those relied upon by the Crown by analysing parts or segments of evidence in a circumstantial evidence case. In deference to the arguments raised, the appendix endeavours to capture many matters raised and relied upon in the submissions made on behalf of [DSJ]. The summary of factual material relating to the "events" in MFIs set out in the appendix also assist in understanding the contentions made on behalf of [DSJ] and [NS].
115It is not clear to me that this paragraph, read in isolation, contains the error for which Defence counsel contend. Rather, it seems to my mind that the trial Judge may have been repeating the concerns that he had identified during oral submissions. It may have been that his Honour was simply stating that his task, as he saw it, did not extend to making an assessment of the weight of alternative inferences by scrutinising those parts or segments of the evidence which had been referred to by Mr McHugh for [DSJ]. If that is the meaning that his Honour intended to convey, as the Crown argued in this appeal, he was quite correct in that regard. I have said enough in the earlier part of these reasons to demonstrate why that is so.
116However, it is necessary to look beyond the particular paragraph and endeavour to see whether his Honour has elsewhere expressed a concluded finding about the broader issue, namely whether it was (or was not) necessary for the purposes of testing the cogency of the Crown hypothesis, to consider any broad alternative or inconsistent inferences arising on the Crown evidence. This topic was raised again by his Honour at paragraphs 68 and 70. His Honour noted that there was no case law authority that had determined whether he should have regard to "the availability and strength of inferences founded in the evidence other than the inferences for which the Crown" contended.
117His Honour returned to the issue at paragraphs 88-111. At 111 his Honour said:
One difficulty, apart from the absence of authority to support the above line of argument is that, at this stage of proceedings in which an advanced ruling is sought on admissibility, there is evident difficulty in determining the availability of inferences and the comparative strength of alternative inferences in relation to a particular fact or matter. The drawing of inferences will, to an extent, depend, as it does with a jury's finding, upon what particular facts or combination of facts the evidence is found to establish. This, at a pre-trial stage, is problematic where there exists a dispute as to primary facts or where the Crown case is largely or wholly a circumstantial one.
118His Honour then listed, in broad terms, a number of matters that had been identified by Mr McHugh as matters in "dispute". Secondly, at paragraph 114 and following, his Honour listed, "alternative inferences" identified by Mr Odgers on behalf of NS. These, in one form or another, referred to the possibility that NS had been "tipped off" by DSJ but had not been provided with the inside information. His Honour carefully set out the submissions made out by Mr Odgers in support of this argument.
119Next his Honour considered a number of authorities that had looked at the issue of similar fact evidence. Having done so, the trial Judge turned to a more general discussion of the evaluation of the probative force of similar fact evidence. He acknowledged Mr McHugh's submission that the probative value of the evidence here, in a number of respects, was low or non-existent, diminished or amenable to alternative explanation or inferences (Appeal book 94, para 134). His Honour commented:
135. A number of submissions for DSJ did not deal with the subject of "alternative inferences" by considering particular evidence referred to in the context of the whole of the evidence in relation to a particular count or the evidence in relation to other counts or both. Rather, the approach was to refer to parts of the evidence in the Crown case relating to particular "events " referred to in MFI 1 as an individual segments [sic] of evidence. As discussed below, such an approach does not sit comfortably with principles that apply to the assessment of probative value of evidence particularly in circumstantial evidence cases.
120His Honour then referred to authority that supported the approach that, in similar fact cases, cogency is demonstrated when regard is had to the particular fact seen in the context of the other evidence in the case ( Sutton v R [1984] HCA 5; (1984) 152 CLR 528 per Brennan J). His Honour's reasoning turned to the propositions advanced in Zhang and Lockyer . He then set himself the task formulated by Simpson J in Zhang :
152. The analysis of Simpson J in Zhang ... and her Honour's expression "... an evaluative and predictive one" are to be understood on the basis discussed above, namely, that, in determining the admissibility of coincidence evidence, the Judge acts upon an assumption that the evidence in question will be accepted. ... On that basis, the question of which I must satisfy myself is, would it be likely that the jury would assign the evidence significant probative value in the sense that the evidence could rationally affect the assessment of the probability of the existence of the facts in issue.
153. I have earlier referred to submissions on behalf of [DSJ] in which a number of items of evidence relied upon by the Crown were either disputed or one of more bases of which were said to be susceptible to innocent or alternative explanations or inferences. The submission was that alternative inferences were open in relation to such evidence. In dealing with those submissions, it is important to identify the role of a court in determining the admissibility of evidence on the basis of an assessment of the probative value. The cases referred to in the paragraphs that follow have considered that role.
121The trial Judge then gave consideration to judicial statements in R v Shamouil; R v Cook [2004] NSWCCA 52 and other authorities which had stressed the importance of the division of functions between a trial Judge and the jury in the trial process.
122Against that background, his Honour entered upon the following discussion (Appeal book 105-106):
165. In the submissions for [DSJ] it was argued ...
...there is nothing in s 98 and s 101 to prevent the Court from assessing the probability of inferences other than those relied upon by the party who seeks to adduce the evidence ...
166. The submission in this respect continued by stating that the Court "must have regard to all the circumstances in which the allegedly similar events are said to have occurred and to all the available inferences" ... and that it was impossible to assess the relative probability or improbability that a similar set of events occurred coincidentally without considering the likelihood of alternative available inferences ...
167. There are a number of matters raised by these submissions in relation to the subject of alternative inferences. Even if evidence on a particular aspect is capable of carrying an alternative inference, that does not detract from the fact that that evidence nonetheless remains open to any rational inference relied upon by the Crown. In other words, in terms of the capability of the evidence in the sense discussed above, it may nonetheless remain capable of carrying significant probative value in the relevant sense as explained in Zhang ... even though other inferences may also be open. This may be because, as a matter of evaluation and prediction, it can be considered likely that the jury would assign it significant probative value and prefer the inference the Crown relies upon. Importantly, the evaluation of the probative value of the evidence, when it is considered along with other evidence, may further enhance the probative value of the evidence in question.
123I pause there to observe that each of these propositions advanced by Hall J is undoubtedly correct. His Honour continued:
169. At the centre of the submissions made on behalf of both accused is the proposition that the probative value of the evidence proposed to be led by the Crown is diminished if the evidence may be considered to be open to alternative inferences or explanations and not only the inferences which the Crown proposes to ask the jury to draw. Not only, it is suggested, must a Judge in evaluating significant probative value determine whether alternative inferences are open but he or she must set about weighing and evaluating the strength of competing inferences, a task that would require, in most cases, that the whole of the relevant circumstantial and other evidence in the proceedings be evaluated, that is, in similar fashion to the approach required of a jury.
170. These submissions are to be assessed, firstly, by the principle that, in determining the admissibility of evidence, a court is to proceed on the basis of taking the evidence in the Crown case on the basis that it will ultimately be accepted by the jury and, secondly, that parts of the evidence must be considered in the whole context of a circumstantial evidence case.
124It may be observed at this point of his Honour's discussion that his reasoning has led him to identify clearly enough the propositions that had been advanced to him on behalf of the defence. His Honour has rightly identified that it was no part of his task to weigh and actually evaluate the strength of competing inferences for the purpose of the s 98 exercise. However, it appears that his Honour has left open, at this point in his reasoning, the question whether, in undertaking the s 98 task, the Court should ignore altogether the possibility of an alternative inference being available arising from the Crown's evidence.
125His Honour next turned to Samadi and the passage from Beazley JA which I have set out earlier. His Honour noted that the point in that case arose in circumstances that were "very different" to those with which he was concerned. His Honour said:
"It is nonetheless instructive to observe the distinction drawn by Beazley JA between the task required by s 98 to be undertaken ( "at the admissibility level" ) from issues that are for a jury's ultimate determination. The former obviously involves a significantly different approach to that involved in the process by which a jury determines subjacent issues of fact (including inferences) and ultimately the facts in issue."
126His Honour, after further reference to the Chief Justice's remarks in Shamouil (and other cases) referred once more to the distinction between the task performed by the trial Judge and that performed by the jury in relation to factual evaluation. His Honour continued:
178. There is evident difficulty in many of the submissions made on behalf of [DSJ] in determining the question of admissibility of evidence under s 98. In relation to many counts, submissions were made as to the absence of evidence on particular or discrete "events" (as, for example, "no actual evidence" of [DSJ] receiving any information as alleged, of what was said in telephone calls or the content of text messages or of acts of [DSJ] to "procure" acts by [NS]). Particular submissions, as noted above, related to the weight to be given to expert evidence on "materiality" in light of certain information in the public domain.
127His Honour then concluded:
181. There is nothing either in the terms of s 98 nor in the analysis of Simpson J in Zhang ... or, in my opinion, in any other authority that indicates or mandates that a judge in assessing "significant probative value" under s 98 must identify the possible alternative inferences that could have support from the evidence or parts of the evidence the Crown proposes to rely upon in relation to particular matters and then set out about sifting and weighing the alternative inferences for the purpose of determining "probative value" .
182. In accordance with the common law trial principles, the determination of available rational inferences is to be made in the context of all relevant evidence at the conclusion of the evidence and then only by the tribunal of fact, the jury. The provisions of s 98 do not state or suggest that, at the level of admissibility, the judge is to conduct an inquiry of all evidence with a view to determining whether more than one inference is open on the basis of particular evidence and whether one possible inference, in fact, trumps another. It is not the function or within the province of a judge in determining an admissibility question under s 98 to predict the inferences or hypotheses that might ultimately be drawn by the jury from the evidence in the course of it determining actual probative value. ...
128In paragraph 184, his Honour noted the difficulty of resolving the comparative availability and strength of alternative inferences or explanations at the admissibility stage. He underlined the fact that "alternative inferences to those relied on by the Crown would often necessarily depend upon how a jury resolves conflicting evidence and how it may determine the probative force of evidence on the basis of the mass of evidence". His Honour endorsed as helpful to his exercise the metaphor referred to by Brennan J in Sutton where similar fact evidence was likened to "the tiles constituting a mosaic". His Honour thought that such a metaphor was equally apposite in relation to coincidence evidence.
129The trial Judge then moved to the conclusions which I have set out earlier.
130I have concluded, not without some considerable hesitation, that the trial Judge did fall into the error of rejecting altogether the need to recognise, in the evaluation process, the existence of alternative inferences inconsistent with guilt arising from the Crown evidence. This was as a consequence of the Crown argument that was advanced to him, his reliance on the passage in Samadi , and arising from his overall concern that it was not his task to intrude into the fact finding area which included the weighing and assessment of inferences.
131In relation to the last matter, his Honour was quite correct. His Honour was also correct in accepting that it is the task of the jury to undertake this weighing task at the point where all the evidence in the trial had been assembled and concluded. None of this, in my opinion, means, however, that the trial Judge in assessing s 98, and making the evaluation required under that section, must ignore and put to one side altogether an alternative explanation that properly arises on the evidence inconsistent with guilt. Of course, it is not for the trial Judge to weigh and assess that alternative explanation, as a jury would do. Nor is the trial Judge required, in that regard, to examine and weigh parts of the evidence only in isolation from the whole body of the evidence.
132However, in the present matter, the trial Judge was required to ask himself whether, for example, the possibility that NS had been "tipped off" about the corporate entities without receiving inside information might otherwise substantially alter the capacity for cogency he thought the coincidence evidence possessed. Similarly, in the case of DSJ, his Honour was required to ask whether, for example, this mass of phone calls and other communications between the two men might mean no more than that they were engaging in social and recreational communications, without reference to stock market trading. If that were a possibility, did it substantially alter his view as to the otherwise significant capacity of the Crown evidence to establish the facts in issue. He had to ask whether the fact that Moody's had information about a vast number of corporate entities, and that, in some cases, there was no direct evidence that DSJ had acquired inside information, substantially altered the high cogency of the coincidence evidence, as he saw it, to prove the facts in issue. In each case, did the possibility deprive the coincidence evidence, taken with the other evidence, of its capacity to prove significantly the Crown case? His Honour, in considering these alternative inferences, may well have taken the view that none of these possibilities had the capacity to diminish the otherwise strong probative value of the Crown evidence. However, in my opinion, they had to be recognised and taken into account in the limited manner I have suggested, and it was an error not to do so.
133For these reasons, I have concluded that error has been demonstrated. The order refusing severance of the counts should be set aside and that issue should be sent back to the trial Judge for re-consideration. It may well be that his Honour will, after applying the approach I have suggested is the correct one, reach precisely the same conclusion both as to the admissibility of the evidence and the need for the counts to be tried together. Those matters will be entirely within his province as trial Judge.
134I propose the following orders:
- Appeal allowed.
- Order made by Hall J on 23 August 2011 dismissing the applications that the charges in the indictment, other than charges 6-9, be tried separately, be set aside.
- The motions are referred back to the trial Judge for reconsideration in the light of this Court's rulings.
135McCLELLAN CJ at CL: I agree with Whealy JA.
136McCALLUM J: I agree with the orders proposed by Whealy JA, for the reasons given by his Honour. I also agree with the additional comments of the Chief Justice.
