The inadmissibility of the interviews
56 I turn to the question of the inadmissibility of the interviews.
57 Section 13 provides for the general case that such statements, confessions, admissions or information made or given shall not be admitted in evidence in proceedings against a child who has provided that material to a member of the police force. It also provides for exceptions to that general case where there is a person as prescribed by s.13(1)(a) present, alternatively, where the person acting judicially in those proceedings is satisfied that there was proper and sufficient reason for the absence of such a person and in addition considers that in the particular circumstances of the case the evidence should be admitted.
58 It can be seen from the structure of the provision that it lays the onus entirely upon the Crown, should it seek to tender the material. The section, by providing the exceptions, provides circumstances in the absence of which the evidence must be, in law, rejected. Other provisions, eg., those in Part 3.4 of the Evidence Act 1995 make further provision for the admissibility and inadmissibility of such material. My view of s.13 is that for the appellant to satisfy this court that, in the admitted absence of such a person as s.13(1)(as) refers to, there was a significant possibility the evidence would be rejected, merely requires the appellant to satisfy us that there is a significant possibility, notwithstanding that the police were misinformed as to his birth date, that a judge would still reject the evidence. The judge is required to do that unless, even if satisfied there was proper and sufficient reason for the absence of such an adult, only if that judge considers that, in the particular circumstances of the case, the evidence should be admitted. On consideration of such a matter, a judge would have regard to the history of provisions of this kind (see Regina v. Aquilina (1978) 1 NSWLR 358; Regina v. Warren (1982) 2 NSWLR 360; McKellar & Booth v. Smith (1982) 2 NSWLR 950; Regina v. Cotton (1990) 19 NSWLR 593; Regina v. Dunn (CCA, unreported 15 April 1992); Regina v. H (1996) 85 A. Crim. R. 481; Regina v. Phung & Huynh (Wood, CJ. at CL, unreported 26 February 2001).
59 In Phung & Huynh (supra), Wood, CJ. at CL. set out the principles as follows:-
"It may be accepted that the purpose of the legislative regime, that now applies to the interview of children, and particularly those in custody following arrest, is to protect them from any disadvantage inherent in their age, as well as to protect them from any form of police impropriety. As to the former, what is required is compliance with the procedure laid down so as to prevent the young or vulnerable accused from being overawed by the occasion of being interviewed, at a police station, by detectives who are likely to be considerably older and more experienced than they are.
This principle derives from what was said by Lee, J in Regina v. Warren (1982) 2 NSWLR 360; by Roden, J. in Regina v . Williams (unreported 9 August 1982); by Hunt, J. in Regina v. Cotton (1990) 19 NSWLR 593; by Carruthers, J. in Regina v. Dunn (CCA, unreported 15 April 1992; and also by Hidden, J. in H (supra).
The role of the support person is to act as a check upon possible unfair or oppressive behaviour; to assist a child, particularly one who is timid, inarticulate, immature, or inexperienced in matters of law enforcement, who appears to be out of his or her depth, or in need of advice; and also to provide the comfort that accompanies knowledge that there is an independent person present during the interview. That role cannot be satisfactorily fulfilled if the support person is himself or herself immature, inexperienced, unfamiliar with the English language, or otherwise unsuitable for the task expected, that is, to intervene if any situation of apparent unfairness or oppression arises, and to give appropriate advice if it appears the child needs assistance in understanding his or her rights.
That position is reinforced by the requirements of the regulations so far as they apply in relation to vulnerable persons, of which a child is one. In particular Regulation 20 requires the custody manager to assist a vulnerable person in exercising that person's rights, and Regulation 26 requires the custody manager to explain to a support person that his or her role is not confined to acting merely as an observer, but also extends to doing the other things specified.
It is important that police officers appreciate that the regime now established is designed to secure ethical and fair investigations, as well as the protection of individual rights, of some significance, which attach in particular to children. Those rights, obviously, are of great importance when a child is facing a charge as serious as murder or armed robbery.
The provisions need to be faithfully implemented and not merely given lip service or imperfectly observed. The consequences of any failure to give proper regard to them is to risk the exclusion of any ERISP, or the product of an investigative procedure, which is undertaken in circumstances where there has not been proper compliance with the law."
60 It must be noted that the law not only requires the affording of an opportunity to a child during an interrogation to exercise on proper advice the option to speak or remain silent, but to have that advice so as to give consideration as to whether, in speaking, they might produce an account which does not do justice to their position.
61 Here it was clear that the police sought to ascertain the appellant's age, prior to arrest, from his mother. That enquiry was so specific it would seem that it was made with a view to interviewing the appellant in the absence of any such person as is referred to in s.13.
62 There would seem to be no good reason why, even if the appellant were over the age of 18, there should not have been an accompanying person permitted. Indeed, the special position of vulnerability referred to by the High Court in McKinney v. The Queen (1991) 171 CLR 468 at 478 and the considerations to which that court adverted in Foster v. The Queen (1993) 113 ALR 1 would plainly raise the advisability of giving consideration to such a course. There was no evidence before us of any consideration of any such course.
63 Having regard to those principles and considerations, I am unable to see that any matter has been advanced which would have the effect of precluding a trial judge from rejecting the interviews when tendered in evidence arising from the particular circumstances of the case, even if such a judge were to hold that there was proper and sufficient reason for the absence of such a person as is referred to in s.13. For my part, I would conclude that the significant possibility test proposed by the Crown for the exclusion of the evidence has been met and I would further conclude, as I have already said, that in the event of exclusion, there was, in my view, a significant possibility that there would have been a different result.
