39As noted above, the Judge determined that the evidence of DaS did not qualify as tendency evidence in the trial of the counts involving the female complainants, and that the evidence of the female complainants was not admissible as tendency evidence in the trial concerning DaS, "because of his gender difference". Arising out of that gender difference, the assaults alleged against the applicant by DaS involved mutual forced masturbation, that is, touching of the child's penis by the applicant and requiring the child to touch the applicant's penis. The Judge acknowledged that there were similarities between the allegations made by the female complainants and those made by DaS.
40The Crown relies principally upon R v Fletcher, and in particular the comments of Simpson J at [52] and [57]. In Fletcher, the tendency evidence established a pattern of behaviour on the part of the accused. The argument advanced by the accused in Fletcher focused upon the nature of the sexual conduct alleged in each case and the date of its alleged perpetration. Simpson J noted that :-
the approach taken on behalf of the appellant is unduly confined, and disguises the true nature of the tendency evidence the DPP sought to adduce. What was contained in the tendency material was capable of establishing a pattern of behaviour on the part of the appellant, incorporating at least the following features. [Those features were the similar ages of the complainants at the time of the alleged conduct, the fact that they were members of practising Catholic families, who were befriended by the accused and who served as altar boys.]
41There is considerable force in the Crown's submission that the evidence of DaS was entirely consistent with the proposed evidence of the female complainants, in that it demonstrated a modus operandi or pattern of behaviour directed towards young relatives between the ages of 6 and 12 years, who visited the premises where the applicant lived with his mother. When each of the complainants reached the age of 14 years, or thereabouts, the applicant ceased his offending towards them in turn.
42Upon WS and DiS attaining the age of 13 or 14, the only remaining children in the extended family were two boys, one of whom was DaS. Thus it was that the applicant turned his attention to DaS and continued that pattern of behaviour, according to the Crown case. Gender was no part of the Crown's application to rely upon tendency evidence. Rather, the tendency evidence acquired its force from the age of the respective complainants, the applicant's ability to control the environment within which the abuse occurred and to exercise influence over each complainant. The decision of this Court in Ford demonstrates that evidence is admissible under s 97(1) if it reveals a tendency to act in a particular way.
43In my opinion, her Honour was incorrect in rejecting the evidence of DaS as tendency evidence. The inevitable consequence of this finding is that the trial of the applicant ought proceed on all charges.
44ROTHMAN J : I have had the advantage of reading, in draft, the reasons of Latham J, for the orders made by the Court on 27 September 2010. I agree with those reasons and, subject to that which follows, they express my reasons for joining in the orders already made. The following comments are additional to those reasons and are not intended in any way to detract from them.
45During the course of the reasons with which I agree, there is a reference to the concept, often referred to in other judgments, of the "pattern of behaviour" and the "similarities between allegations", being a comparison between the "tendency material" and the conduct that gives rise to the charges.
46Section 97, however, does not require, at least expressly, "similarities in the events or the circumstances in which they occurred" (see s 98 of the Evidence Act, hereinafter "the Act"). The tendency rule is satisfied by evidence of character, reputation or conduct, or a tendency, to prove a tendency to act in a particular way. Section 97 of the Act is not concerned with the improbability of coincidence, which is the concern of s 98 of the Act.
47Before either s 97 or s 98 of the Act is applicable, material must be relevant. The proposed evidence must be material which "could rationally affect (directly or indirectly) the assessment of the probability of the existence of a fact in issue": s 55 of the Act. Prima facie, all relevant evidence is admissible. Sections 97 and 98 then exclude evidence that would otherwise be relevant, unless the evidence satisfies the preconditions there prescribed.
48There is a distinction between tendency evidence and coincidence evidence (previously, and often still, called similar fact evidence) even though, often, the evidence may be of the same character. The difference is the use to which the evidence is put. Tendency evidence is used to support a process of reasoning, namely, because a person has a tendency to act in a particular way, the person is more likely to have acted in that particular way on this occasion. Similar fact evidence is used to prove the improbability that the alleged events occurred coincidentally.
49Tendency evidence, and tendency reasoning, is not admissible, or able to be used, unless it has significant probative value. The tendency must go beyond a propensity to engage in crime, or even criminal conduct of a general kind, but must show a propensity to engage in criminal conduct of the kind charged, or conduct associated with it. It is, however, unnecessary to have a striking pattern or similarity between the charged incident and the other incidents upon which it is sought to prove a tendency.
50In R v Ford [2009] NSWCCA 306, Campbell JA, with whom Howie J and I agreed, observed:
"The second flaw is the judge's apparent view that the tendency evidence must itself show a tendency to commit acts that are closely similar to those that constitute the crime with which a particular accused is charged. That is not so. All that a tendency need be, to fall within the chapeau to section 97(1), is 'a tendency to act in a particular way'." (At [38].)
Later, at [125], Campbell JA said:
"In my view there is no need for there to be a 'striking pattern of similarity between the incidents'. All that is necessary is that the disputed evidence should make more likely, to a significant extent, the facts that make up the elements of the offence charged. In my view, it meets that test."
(See also Regina v PWD [2010] NSWCCA 209 at [57]-[65], per Beazley JA, with whom Buddin J and Barr AJ agreed.)
51Because of the heavy burden that the evidence must have a significant probative value, and utilising the pre-Evidence Act judgments as a guide, it is necessary to show more than a general propensity. Thus, evidence of heterosexuality, of itself, is not significant to a sexual offence against the other gender. And evidence of homosexuality, of itself, is not significantly probative of a charge of sexual misconduct involving the same gender. As a consequence of the need to show a particular tendency, often a notice of tendency evidence is drafted in a way which makes it difficult to determine whether the evidence is sought to be adduced as tendency evidence or similar fact/coincidence evidence.
52In this case the tendency sought to be proved is the applicant's tendency to act in a particular way and/or to have a particular state of mind, namely:
"(i)to show a sexual interest in ... children of relatives aged 14 years or below that were visiting his home;
(ii)in connection with his [aforesaid] sexual interest ... to remove, or cause to be removed, for sexual purposes, articles of clothing;
(iii)to touch [such persons] in a sexual manner;
(iv)... in bed, under bed clothes in his bedroom;
(v)... whilst ... engaged in watching television or videos;
(vi)to direct [such] children ... to touch him in a sexual manner;
(vi)to engage in sexual intercourse with [such] children of relatives...."
53For all the reasons given by Latham J, each person's evidence, sought to be adduced for this purpose, is evidence that the applicant has a tendency to act in the particular way described and has significant probative value. It is admissible under s 97 of the Act.
54The evidence is each alleged victims' version of offences and, if otherwise drafted or notified, may have been able to be utilised as coincidence evidence, as well. The allegations in each are strikingly similar in the circumstances of their alleged occurrence. But that should not confuse the test in s 97 of the Act.
