[26] It is appropriate to consider these grounds together. They are complementary in the sense that the second ground asserts that the discretion to sever miscarried (ground 1) because the trial judge erred in his conclusion that the evidence of the several complainants was 'cross-admissible'. Trial counsel for the applicant had applied to the judge to sever the counts as between the six complainants on the basis that the evidence to be given by each complainant in respect of the counts relating to her was irrelevant to and, thus, inadmissible in support of the counts relating to the other complainants. The trial judge rejected that application, and declined to sever the counts. He did so on the basis that the evidence to be given by each of the complainants of the conduct of the applicant in committing the alleged offences against her bore such a similarity or relationship to the conduct of the applicant alleged by the other complainants as to render the evidence of each 'mutually admissible' in the trials relating to the others. Having reached that conclusion, it became pointless - as he said - to order severance in the manner sought. In so concluding, his Honour's discretionary exercise was consonant with principles laid down in this Court in such cases as R v TJB, R v GAE, R v Glennon. It should, nevertheless, be pointed out that where multiple sexual offences against more than one complainant have been properly joined in the one presentment in accordance with the Presentment Rules contained in Sch VI to the Crimes Act, the discretion to sever, at least in this State, is not necessarily dictated by 'mutual admissibility' or the lack thereof. The amendments to s 372 of the Crimes Act made by the Crimes (Amendment) Act 1997 (to which I have referred in paras [2] and [3] above) were introduced to ensure that trial judges carefully considered whether severance was necessary even where the judge concluded that the evidence of complainants was not 'cross-admissible'. Those amendments introduced sub-s (3AA) and (3AB) into s 372. Subsection (3AA) provides that:
Despite subsection (3) and any rule of law to the contrary, if in accordance with this Act, two or more counts charging sexual offences are joined in the same presentment, it is presumed that those counts are triable together;
and subs (3AB) provides that:
The presumption created by subsection (3AA) is not rebutted merely because evidence on one count is inadmissible on another count.
As this Court pointed out in R v KRA, these amendments make it appropriate that severance of the presentment :
should be approached on the basis that the rule of law or practice which had hitherto existed in this State had been, and was intended to be, modified by these amendments in favour of the more pragmatic approach adopted in the case of R v Christou.
In particular, the Court pointed out that the trial judge should consider whether potential prejudice could be overcome by appropriate directions, bearing in mind that juries can be trusted to heed the directions of the trial judge.
[27] Nevertheless, it seems to me to remain a sound approach in cases such as the present for the trial judge, in exercising the discretion given by s 372(3), to determine whether the evidence of the several complainants is cross-admissible because such a determination will - in most cases - be a powerful factor influencing the discretion. The capacity to ensure a fair trial for the accused must always be the dominant consideration governing the exercise of the discretion; and the more complainants there are whose evidence is not admissible in the trials affecting other complainants, the more difficult it will be for adequate directions to be given by the trial judge to avoid prejudice occurring to the accused. To that extent, the views expressed by the High Court in De Jesus and Sutton (to which I have referred in [3]) will remain influential in this State.
[28] In this application, Mr Priest submitted that the trial judge erred in his conclusion that the evidence of the complainants was cross-admissible, and that, accordingly, his discretion not to sever had miscarried. In its essence, the applicant's contention was that the judge should have ordered separate trials in respect of the counts relating to each complainant. Mr Priest's submission was that there was insufficient 'connecting link' or 'underlying unity' between the evidence of the various complainants to warrant the judge's conclusion that their evidence was mutually admissible. The nature of the conduct alleged was quite different Mr Priest submitted, and a proper appraisal of the evidence should have led his Honour to conclude that the evidence of each complainant fell into its own 'water-tight' compartment. When properly analysed, so Mr Priest submitted, the conduct of the applicant described by the various complainants was quite dissimilar and that the 'similarities' relied upon by the judge demonstrate nothing more than 'rank propensity'. In amplifying this submission, Mr Priest referred in detail to what he submitted were the differences between the allegations by the different complainants, and submitted that there was nothing which could be labelled as a 'modus operandi' or significant similarity of conduct which would render the evidence of one complainant admissible in the notional trials relating to the others. He submitted that 'similar fact' evidence, in any case, will only be received with 'great caution' because the risk of prejudice is high and that, absent the 'similarities' being 'striking', the evidence will usually lack the requisite probative force to render it admissible.
[29] Questions of the type which confronted his Honour in this case are not easy to resolve; the difficulties being compounded by the fact that the trial judge had - at least at the outset of the trial - only the depositions to work from. In this State, the issue is to be determined in accordance with s 398A of the Crimes Act; a provision which was introduced into the legislation by the Crimes (Amendment) Act 1997; the same legislation which introduced the amendments to s 372. Relevantly, for the purposes of this application, s 398A provides as follows:
