Viewed in this way, his Honour concluded (at [44]) that evidence of the child's response to the invitation to participate the line-up was "direct proof" of a relevant matter, that is, his refusal to do so, and "was no proof of an admission."
20 The trial judge in the present case noted Bryson J's observations (at [18] & [47]) that the question whether a statement is adverse to its maker's interest is to be determined at the time it is tendered in evidence, not at the time it was made. A statement which appeared innocuous or exculpatory when it was made might later acquire a different significance in the light of the evidence and the issues at a trial. Generally, after his examination of the reasoning in Horton and A, his Honour concluded:
In the light of that discussion, it seems to me that the ambit of whether an act or utterance constitutes an admission under s 13 can be quite wide, and sufficiently wide to embrace matters which are not obviously, or necessarily, or immediately, inculpatory of an accused.
In the present case, there is, in my view, no doubt that the provision of the photograph was adverse to the interests of the accused because, in effect, he was compelled to put his neck in the noose for photographic identification. …
To the extent that an admission has to be against the interests of the person, at least by the time its admission into evidence is considered, the circumstances here sufficiently satisfied that aspect of what is understood by an admission.
21 By saying that the respondent was "in effect… compelled to put his neck in the noose for photographic identification", we do not understand his Honour to mean that he was in fact compelled to pose for the photograph, as opposed to doing so without informed consent. The words need to be understood in their context. His Honour was conveying, perhaps in somewhat rhetorical language, that the respondent submitted to being photographed in ignorance of the fact that the photograph might be used to identify him as an offender.
22 His Honour then went on to consider whether the respondent's submission to photography constituted an "act or utterance" capable of being construed as an admission, and arrived at the conclusion expressed in the passages from his judgment previously quoted. In so doing, he had regard to the fact, recognised at common law and now enshrined in the definition in the Evidence Act, that an admission can be made by conduct, for example, by flight: R v Cook [2004] NSWCCA 52, per Simpson J at [21] - [25]. In summary, his Honour held that the respondent's posing for the photograph amounted to an admission because it enabled the police to obtain a likeness of him which, in the event, proved to be adverse to his interest in the outcome of his trial.
23 Another case to which his Honour referred, although he did not find it of "significant assistance" in resolving the issue, was R v Knight [2001] NSWCCA 114. That appellant had been found guilty of a number of offences in the nature of forgery and the evidence of a handwriting expert was an important part of the case against him. Among the documents submitted to that expert containing samples of the appellant's handwriting were "fingerprint information forms" completed by him when he was arrested on three occasions, one of those being his arrest for the subject offences. These were standard forms dealt with by the New South Wales Police Instructions and, on their face, they required the appellant to write down certain personal particulars. It was not suggested to him that he had any choice about that matter and he was not cautioned about the use which might be made of the forms.
24 Two of the forms were completed before the Evidence Act came into force, and one of them after it. The argument on appeal was that they should have been rejected on the basis that they were "admissions or analogous to them": the first two on common law principles arising from considerations of public policy and fairness to the appellant, and the third in the exercise of the discretion conferred by s138 of the Evidence Act, including the absence of a caution of the kind required by s139. Greg James J, with whom Heydon JA and Studdert J agreed, held (at [59] ff) that a suspect's handwriting is embraced by the expression "all such particulars as may be deemed necessary for the identification" of that person in s353A(3) of the Crimes Act and, accordingly, is one of the particulars which police are entitled to obtain by virtue of that subsection, whether or not the suspect consents: subs (3D).
25 This, together with other aspects of the case which need not concern us, formed the basis of Greg James J's conclusion that neither the public policy discretion at common law nor s138 of the Evidence Act required the rejection of the forms. It is the manner in which his Honour dealt with the submission that the provision of the handwriting samples was tantamount to an admission that is significant for present purposes. His Honour said (at [78] - [80]):
78 As to the submission that the provision of the handwriting sample was or was analogous to providing an admission, I see no basis on which it could be concluded that the doctrines as to self-incrimination referred to in Sorby v The Commonwealth (1983) 152 CLR 281; Environment Protection Authority v Caltex Refining Co Pty Limited (1992-93) 178 CLR 477 have here, any applicability, particularly since the section, in my view, authorises the obtaining of the samples and considering how the matter was regarded at common law. In Carr (supra) in the Court of Criminal Appeal at 610, the analogy to self-incrimination is expressly rejected.
79 In Sorby (supra) at 292, Gibbs, CJ referred to the requirement of an accused to provide a fingerprint or show his face or some other part of his body so that he may be identified, or to speak or to write so that the jury or another witness may hear his voice or compare his handwriting, specifically as outside the ambit of the privilege against self-incrimination. Brennan, CJ cited that passage in Bulejcik v The Queen (1995-96) 185 CLR 375 at 381.
80 Under the Evidence Act the provisions as to admissions contained in Part 3.4 and s139 apply only to matters caught by the statutory definition of that term and its essential element "representation" as contained in the dictionary. I would not consider the handwriting to be a representation nor could I see any of the provisions of that part as applicable to lawfully obtained evidence where the particular enabling statute negates any requirement for consent. (Our emphasis)
26 It will be seen that Greg James J decided the point largely by reference to the privilege against self-incrimination, one of the cases he cited being Carr (supra). His Honour found that the privilege was not available because the police had a statutory right to obtain the handwriting samples. No doubt, it was because of this decision and the authorities referred to by Greg James J that the trial judge in the present case was concerned with the question whether the police had a right to compel the respondent to pose for the photograph and, if they did not, whether he had given his informed consent to that course. However, whether an act or utterance is subject to the privilege against self-incrimination cannot be determinative of whether it is an admission and the authorities do not suggest that it is.
27 So much is apparent from the last paragraph of Greg James J's judgment quoted above. His Honour was saying that, in any event, the provision of the handwriting could not amount to a "representation" for the purpose of the definition of "admission" in the Evidence Act. He went on to observe that none of the provisions of Pt3.4 of that Act were applicable to evidence which could be obtained lawfully in the absence of consent. That Part deals with admissions and, no doubt, his Honour was there referring to the exclusionary provisions within it. The observation appears to be independent of his Honour's finding that the handwriting, by its very nature, could not amount to an admission.
28 In their different ways, the decisions in Knight and A (supra) provide guidance for the resolution of this issue in the present case. In A, Bryson J held that the plaintiff's refusal to participate in a line up could not amount to an admission as that word is understood in ordinary usage and in the law of evidence, an understanding preserved by the definition in the Evidence Act. It was not a representation in the relevant sense. To treat it as an admission would be to distort the meaning of both those words. The same was true of the provision of the handwriting samples in Knight, as it is of the present respondent's posing for the photograph. That he may not have given his informed consent to doing so and that it proved to be adverse to his interest in the outcome of the proceedings does not alter the fact that it cannot be characterised as an admission.
29 Nor can it be characterised as the giving of information, for the purpose of s13 of the Children (Criminal Proceedings) Act. No light is cast upon the meaning of that expression in the second reading speeches relating to s13 and its predecessor, s81C of the Child Welfare Act. Senior counsel for the Crown in this Court argued that the word "information" in the subsection should be read ejusdem generis with the other words in it, that is, "statement", "confession" and "admission." That is not a matter which we need determine. It is sufficient to say that the notion of giving information necessarily involves an assertion of fact and, again, it would distort the meaning of that expression to apply it to the respondent's posing for the photograph. Senior counsel for the respondent before us submitted that information can be conveyed by conduct, citing the example of a suspect indicating relevant locations to investigating police. No doubt, that is so, but conduct of that kind is still assertive and would almost invariably be accompanied by, or supplementary to, oral communications.
30 Accordingly, we are satisfied that his Honour fell into error in this respect. The admissibility of the photograph was unaffected by s13 of the Children (Criminal Proceedings) Act, s90 of the Evidence Act and s281 of the Criminal Procedure Act. It is necessary, then, to turn to the other bases upon which the evidence was rejected and, for that purpose, to examine more closely some of the evidence on the voir dire.
Part 10A of the Crimes Act/s138 of the Evidence Act
31 His Honour found that, at the time the photograph was taken, the respondent was "a person under arrest" for the purposes of Pt10A of the Crimes Act and that the police had failed to comply with the requirements of the Crimes (Detention After Arrest) Regulation 1998 in respects that were significant. This finding, in conjunction with the other findings to which we have referred, led his Honour to conclude that the photograph had been obtained in consequence of an impropriety for the purposes of s138(1)(b) of the Evidence Act. It followed that the photograph was not to be admitted into evidence unless the desirability of admitting it outweighed the undesirability of admitting evidence that had been obtained in that way.
32 The Crown prosecutor submitted that his Honour was wrong to find that the provisions of Pt10A were of application. In the alternative, he submitted that the exercise of his Honour's discretion under s138 had miscarried.
33 The objects of Pt10A are stated in s354 as follows:
354 The objects of this Part are:
(a) to provide for the period of time that a person who is under arrest may be detained by a police officer to enable the investigation of the person's involvement in the commission of an offence, and
(b) to authorise the detention of a person who is under arrest for such a period despite any requirement imposed by law to bring the person before a Magistrate, authorised person or other person or court without delay or within a specified period, and
(c) to provide for the rights of a person so detained.
34 As we have said, the police were present at the respondent's home for the purpose of executing a search warrant. The photographs were taken at a time towards the latter part of the search and before it was completed. It was common ground that the respondent had not been arrested in the conventional sense.
35 For the purposes of Pt10A a person under arrest is defined by s355(2) as follows:
(2) A reference in this Part to a person who is under arrest or a person who is arrested includes a reference to a person who is in the company of a police officer for the purpose of participating in an investigative procedure, if:
(a) the police officer believes that there is sufficient evidence to establish that the person has committed an offence that is or is to be the subject of the investigation, or
(b) the police officer would arrest the person if the person attempted to leave, or
(c) the police officer has given the person reasonable grounds for believing that the person would not be allowed to leave if the person wished to do so.
36 His Honour found that the respondent had been in the company of the police for the purpose of participating in an investigative procedure at the time the photograph was taken and that each of paras(a) and (c) was satisfied. It followed that those provisions of Pt10A and the Regulation that are not confined to persons under arrest at a police station or at another place of detention applied to the respondent.
37 The expression "investigative procedure" is not defined for the purposes of Pt10A. His Honour noted the concession by Detective Ryan, the officer in charge of the search, that he had wished the photograph to be taken for potential use in a photo board to be shown to identifying witnesses. His Honour considered that the taking of a photograph would in the circumstances of this case, in ordinary parlance, be an investigative procedure.
