32 RP nonetheless repeated that she was still at school when she moved into the appellant's house, and said that the first occasion was when she was still at school but was home because she was unwell. She said that she and another of the appellant's daughters used to go to school together, and that "as far as I can remember" it was six weeks before her sixteenth birthday.
33 To this may be added evidence from the appellant's son RI, at the time aged about 14, estimating RP's age in the bracket 16 to 17 but, perhaps more importantly, saying that his parents "got her onto a pension" and that that happened when RP came to live with them; the thrust of his evidence was that the two things happened in close proximity in time.
34 RP's mother gave further evidence that RP was not getting a pension when RP was living with her. When it was put to RP's mother in cross-examination that RP left home in 1983 rather than 1982, she answered "I don't know".
35 Secondly, RP was asked about the state of the appellant's house when she moved in. She said that there were six bedrooms, that some extensions had been just finished save for one wall which had not been put up, and described the bedroom arrangements. Papers from a file of the Department of Housing indicated that the extensions producing six bedrooms were only a proposal as at early 1983.
36 The judge said that it was clear to him that RP had intellectual problems, but that she nevertheless gave evidence in a clear and understandable manner and that he formed the opinion that she was an honest witness. Correctly noting that her reliability had to be assessed as well as her honesty, he said that evidence given by a witness of low average intelligence about events occurring more than twenty years ago would have required a warning to a jury, and that he looked very carefully at her evidence and in the light of the other evidence before him. He said he had come to the conclusion "[t]hat the complainant's evidence is reliable, although, as I shall indicate, there may be some matters about which she is mistaken".
37 As to the matters referred to above, his Honour said that he considered that RP's mother was "an honest and reliable witness" and that her evidence "enables me to be convinced beyond reasonable doubt that the complainant was under the age of 16 years when she went to live in the household of the accused". His Honour continued -
"It is clear that at some point after she went to live at the [appellant's house], she was receiving a pension of some kind and the benefit of this went to the accused. However, I see no reason to conclude that she was getting this in the period up to August 1982, when she was still at school.
There was a great deal of cross-examination of the complainant about her age when she went there. A file from the Housing Commission was tendered in evidence with a view to showing that she was wrong in her claim that she went to live with the [appellant's family] shortly before her 16th birthday. This file establishes when some alterations were made to the [appellant's] house and on one view of it, shows that she was mistaken about the layout of the house and how many bedrooms there were at various stages.
In my opinion, the cross-examination did not damage the credit of the complainant. I am satisfied beyond reasonable doubt, having made allowance for her low intelligence and the fact that she was speaking of events of many years ago, that she was on 15 years old when she went to live with the [appellant's family] and that it was a matter of weeks before her 16th Birthday in 1982 that she went to live there."
38 If the determinations at the special hearing had been by a jury, the question would have been whether it was open to the jury to be satisfied beyond reasonable doubt that the appellant had committed the offences, bearing in mind that the jury was entrusted with the primary responsibility to make the determinations and the advantage of the jury in having seen and heard the witnesses give evidence before them: Jones v The Queen (1997) 191 CLR 439 at 451. With additional regard to the judge's reasons for his determinations, the question is the same in a hearing before a judge alone (see R v Kurtic, CCA, 16 February 1996, unreported).
39 The appellant submitted that RP's low intelligence and the passage of time should have caused his Honour to exercise particular caution in accepting RP's accuracy concerning her age at the time of the alleged offences, and that the evidence concerning payment of board from the pension and concerning the extensions to the house at the least raised reasonable doubt. It was submitted that it was as likely that RP was correct in her recollection of those matters as she was in her recollection of moving into the appellant's house while still at school.
40 The Crown submitted that the judge had the benefit of seeing and assessing the witnesses and was able to assess their reliability, that there may have been some distortion of RP's evidence by putting to her in leading form that she had paid board from the time she moved into the appellant's house, and that there was ample evidence on which the judge could be satisfied beyond reasonable doubt that RP was under 16 at the time of the offences the subject of counts 1 and 2.
41 In my opinion, the Crown's position should be accepted. There were discrepancies in RP's evidence, but a constancy that she was at school at the time of the alleged offences and that they occurred prior to her sixteenth birthday. Her mother's "I don't know" could well have been no more than a not uncommon inability to put a year to an event. It was a classic jury exercise for the judge, to decide what in the evidence was reliable despite discrepancies and despite the professed recollection as to the extensions. This could readily enough have been seen as mistaken recollection not impugning the evidence of the time of occurrence of the offences, when the extensions may not have been begun until well into 1983. RP's intellectual state called for most careful consideration of her evidence and regard to the other evidence, and the judge directed himself accordingly. I am not persuaded that this ground has been made out.
