TENDENCY AND COINCIDENCE EVIDENCE
20 As I have observed, a critical question for determination, in relation to the admissibility of the evidence, was whether it qualified as tendency or coincidence evidence. That question was dealt with somewhat briefly by her Honour early in the judgment, by reference to the similarities which the Crown had identified in point form (a) to (p), in its submissions. Relevantly, they were said to be as follows:
" Although the charges alleged against the accused occurred at different times over this 11 year period they have a common thread involving the following similarities:
(a) The 4 boys were all students at [named school]
(b) They were all young, aged between 12 and 14 years;
(c) The accused was working as a gym teacher at the school;
(d) All involved penis play;
(e) All occurred when the boys were in their school uniforms or gym clothes;
(f) Two occasions (GDR para 10 onwards and JPMCR para 11) occurred whilst the accused supported the boys on gym equipment and he touched them on the crotch;
(g) Three occasions (SAL,MHS and JPMcF) the approaches were made to the boys in the privacy of the sports room or his office (which is located in the sports room);
(h) Three occasions (SAL, MHS and JPMcF) each boy was grabbed from behind ;
(h) Three occasions the accused inserted his hand both inside their pants and underpants (SAL para 8, MMS para 20 and JPMcF para 12);
(i) Three occasions each boy was restrained in the use of his hands (GDR's wrists were strapped to the high bar para 11, JPMcF hands on the parallel bar para 11, SAL had his hands held by the accused behind his back para 7);
(k) With all boys he watched them shower whilst they were naked (GDB para 9; SAL para 2);
(l) With two boys he playfully slapped them on the bottom (GDG and MMS para 18);
(m) With two boys he spoke about sexual matters - with MMS he spoke about "wanking", penis size, a woman 'getting wet' during sex and foreskin para 14 and 15; he asked JPMcF whether pictures of Samantha Fox gave him an erection para 10;
(n) Three boys were ones who had difficulties at school - GDG had problems at school and learning difficulties (petit mal epilepsy p. 27 committal; and misbehaved in mid 1991 called another boy's sister a slut and disciplined by the accused p. 25); MMS was bullied by other students at the school (para 6); JPMcF's parents were separated and got into trouble with the deputy School Principal for having pornographic magazines;
(o) those same three boys he gave special attention or told them they were special;
(p) SAL was summonsed from Economics Class (para 6); GDG was told "Mr F wants you over at the high bar" (p. 28)"
21 Although, on the face of the reasons for judgment, there are suggestions that the threshold question of admissibility was determined by reference to coincidence, it does seem that the evidence was also considered to qualify by reference to tendency. These are of course separate considerations, and any direction to the jury would need to reflect the differences which arise.
22 It was necessary for her Honour to give careful consideration, so far as the Crown placed reliance on s 97 of the Evidence Act, to whether or not the conduct alleged by the various complainants was capable of showing that he had a tendency (or propensity) to touch boys on the penis without their consent and had the particular state of mind necessary to make that act one of indecent assault. If it had that character then before it was admissible, the Crown still had to show that it had a "significant probative value" (s 97(1)(c)) - an expression which has been held to mean that the evidence must be more than merely relevant, and to be "important" or "of consequence" (R v Lockyer (1996) 89 A Crim R 457). Its significance, it has been held, depends upon the nature of the fact in issue to which the evidence is relevant, - here whether the respondent did touch the complainants on the penis either inside or outside their shorts in circumstances amounting to an indecent assault - and upon the significance which the evidence may have in establishing that fact: R v Lock (1997) 91 A Crim R 356.
23 Since the evidence was, in this case, to be tendered by the Crown, it was also necessary that it be shown to have passed through the s 101(2) threshold - i.e. that its probative value substantially outweighed any prejudicial effect it might have had on the respondent. The combined effect of s 97(1)(b) and s 101(2) was held in Lock to require an application of the same test as that approved in Pfennig v The Queen (1995) 182 CLR 461 at 481 to 483, and in Hoch v The Queen at 295, namely that the evidence bears no reasonable explanation other than the happening of the event or events in issue. (See also BRS v The Queen (1997) 191 CLR 275 and KRM v The Queen (2001) 75 ALJR 550).
24 In Regina v OGD (No 2) [2000] NSWCCA 404, it was held that, if the Crown failed to exclude the reasonable possibility of concoction on the part of the proposed witness or witnesses, the evidence must be excluded, not because of the rule in Hoch, but because of the requirement in s 101(2) of the Evidence Act: see also Regina v Colby [1999] NSWCCA 261 at para 107 to 111.
25 Independently of this provision, the question of admissibility also calls for a consideration of ss 135 and 137 of the Evidence Act, as to the exercise of which, Hoch was held in OGD (No 2) to provide a guide.
26 So far as the Crown relied on s 98 of the Evidence Act, it had to establish first that the acts alleged by the complainants were "related events", i.e. that they were "substantially and relevantly similar, and that the circumstances in which they occurred were substantially similar" (s 98(2)). Next, it had to meet the requirements noted in relation to the tendency evidence, namely, that the evidence would have "significant probative value" (s 98(1)(b), and that its "probative value substantially outweighed any prejudicial effect which it may have had on the respondent" (s 101(2) - that is, the prejudice associated with the risk of the tribunal of fact using the evidence inappropriately: Regina v Lockyer at 460 and Regina v Colby [1999] NSWCCA 261 at para 97). Once these requirements were met then the evidence would be admissible to prove that, "because of the improbability of the events occurring coincidentally," the respondent did the act alleged in any given count and/or that he had the particular state of mind alleged in relation to it, for example to rebut any defence of accident (Thompson v The Queen (1989) 169 CLR 1).
27 In Pfennig it was held that it was not necessary, under this provision, to speak in terms of a "striking similarity", or "underlying unity" or other similar description previously employed in decisions depending upon the admissibility of similar fact evidence at common law, the test being one of substantial and relevant similarity.
28 However, for all practical purposes, questions of admissibility under this heading are likely to be determined by similar considerations to those applied at common law, in that it would be necessary to show that:
