The Probation and Parole officer's evidence
47 I have already referred to parts of the officer's statement, file notes and evidence in the voir dire hearing and to the part of Judge Maguire's judgment relating to her evidence.
48 There was evidence to support each of Judge Maguire's seven primary findings of fact about the officer and those findings of fact could not be successfully challenged.
49 Having made those primary findings of fact, Judge Maguire did not in terms say that the evidence which the Crown sought to adduce from the officer was evidence which had been unlawfully obtained but such a finding is clearly implicit in his Honour's finding that the obtaining of the officer's evidence was fundamentally flawed. The reason given by his Honour for such a finding was that the Probation and Parole officer had misconceived her functions and had undertaken functions, namely the investigation of criminal activity and the interrogation of suspects, which belonged to the Police Service and the Department of Corrective Services.
50 I am, with respect, unable to agree with the reason given by his Honour for his finding. At the second case meeting on 20 June 2002 the officer, as the member of the New South Wales Probation Service having the responsibility of supervising and guiding the respondent, who had pleaded guilty to and been convicted of an offence of possessing child pornography, formed a judgment that the respondent was not being honest in denying that he fantasised about having sex with children and made a further judgment that "supervision will need to focus on (the respondent) admitting his fantasies and then being able to challenge him on the possibility that he could act on his fantasises". Pursuant to this judgment made by her, the officer questioned the respondent, with a view to eliciting admissions from him that he did have sexual fantasies about children.
51 I do not consider that it was open to the judge of first instance to find that, in proceeding as she did, the Probation and Parole officer "completely misconceived her duty" and assumed functions which could only properly be performed by the Police Service or the Department of Community Services. The officer was performing her functions as a Probation and Parole officer in the way in which she as an experienced officer considered they should be performed, in order that she should provide effective supervision and guidance for the respondent and I do not consider that it was open to Judge Maguire to find that the officer was wrong in deciding how she should perform her functions. In questioning the respondent the officer was not purporting to act as an agent of the Police Service. I accordingly consider that Judge Maguire's finding, that evidence by the Probation and Parole officer of admissions made to her by the respondent was evidence improperly obtained because the officer had misconceived what her proper functions were, was erroneous and should be vacated.
52 Even if Judge Maguire's finding, that the evidence of the Probation and Parole officer had been improperly obtained for the reason given by his Honour, had been correct, I consider that there were errors in his Honour's exercise of the power to exclude improperly obtained evidence conferred by s 138 of the Evidence Act .
53 His Honour did not expressly state the test in subs (1) of s 138, that is that the evidence which has been obtained improperly should not be admitted "unless the desirability of admitting the evidence outweighs the undesirability of admitting evidence that has been obtained in the way in which the evidence was obtained". However, I would be prepared to accept that his Honour did apply the statutory test.
54 However, when referring to the matters in subs (3) of s 138, his Honour said, with reference to par (c) ("the nature of the relevant offence"), that he did not see the nature of the offences as having any particular bearing. One of the offences charged (charge five) was an offence of having sexual intercourse with a child under the age of ten years and was a very serious offence carrying a maximum penalty of imprisonment for twenty-five years. In R v Dalley (2002) 132 A Crim R 169 the majority of the Court of Criminal Appeal (Spigelman CJ at 172 (7) and Blanch AJ at 189 (102)) held that the public interest in the conviction and punishment of those guilty of crime is entitled to greater weight in a case of crimes of greater gravity both at common law and pursuant to s 138(3)(c). With reference to pars (d) and (e) of s 138(3), his Honour held that the impropriety was "of the gravest kind" and that the impropriety was deliberate. In my opinion, there was no evidence capable of supporting either of these findings.
55 I have already held that Judge Maguire's finding, that evidence by the Probation and Parole officer was improperly obtained evidence for the reason given by his Honour, was erroneous and should be vacated. However, that does not necessarily mean that the evidence by the Probation and Parole officer would be admissible in a trial of the respondent. It may be that there is some other basis on which the evidence should be excluded under s 138. Before Judge Maguire counsel for the respondent submitted that the Probation and Parole officer's evidence, if not excluded under s 138, should be excluded under s 90 of the Evidence Act (the discretion to refuse to admit evidence of admissions, if, having regard to the circumstances in which the admissions were made, it would be unfair to the accused to use the evidence) or under s 137 of the Evidence Act (the obligation of a court to refuse to admit evidence adduced by the prosecution if its probative value is outweighed by the danger of unfair prejudice to the accused). At the hearing before this Court other conceivable grounds on which the Probation and Parole officer's evidence might be excluded were mentioned.
56 At the hearing before this Court counsel for the respondent submitted that this Court should itself decide all questions concerning the admissibility of the evidence of the Probation and Parole officer. Counsel for the Crown submitted that this Court should decide all questions of admissibility under s 138 of the Evidence Act but should not enter upon a consideration of other sections of the Evidence Act .
57 In my opinion, notwithstanding the power granted to this Court by s 5F(5)(b) of the Criminal Appeal Act , this Court should not in the present case take upon itself to decide any further questions concerning the admissibility of the evidence of the Probation and Parole officer (apart from Judge Maguire's finding that the Probation and Parole officer's evidence was also inadmissible as tendency evidence). The present appeal is an appeal by the Crown and par 1 of the Crown's grounds of appeal, which relates to the evidence of the Probation and Parole officer, is limited to asserting that the judge of first instance erred in refusing to admit evidence "as not satisfying tests for admissibility under s 138 of the Evidence Act and/or constituting inadmissible tendency evidence". More fundamentally, I consider that this Court as an appeal court should be cautious in taking upon itself to decide questions about the admissibility of evidence which have not been decided or even considered by a judge of first instance. This is particularly so, when the questions involve an exercise of discretion or the assessment and weighing of criteria such as "probative value" and "unfair prejudice". I note that in R v Sophear Em [2003] NSWCCA 374, an appeal under s 5F(2) of the Criminal Appeal Act, this Court held that a decision by the judge of first instance excluding certain evidence had been erroneous and should be vacated but considered it inappropriate to make any further ruling of its own about the admissibility of the evidence. As stated, Sophear Em was an appeal under s 5F(2) and not s 5F(3A), but the powers of the Court of Criminal Appeal conferred by ss (5) of s 5F are the same in both kinds of appeal.
