(c) consequence of non-compliance
14The second issue concerns the consequence of a failure to give an adequate instruction in accordance with the statutory provision. In The Queen v WG [2010] VSCA 34, Warren CJ, Nettle and Ashley JJA drew a distinction between a condition of competence and a condition of admissibility: at [35]. The Court continued at [36]:
"In our view, the importance of that distinction is that, although compliance with a condition of competence is essential (in that the testimony of an incompetent witness is not evidence at all), and thus it has been held that failure to comply with the requirements of ss 13(2)(a), (b) and (c) of the Uniform Evidence Act is productive of a miscarriage of justice to which the proviso cannot be applied, a condition of admissibility can ordinarily be waived and, if so waived, failure to comply with the condition does not result in a miscarriage of justice or at least in a miscarriage to which the proviso cannot be applied."
15The reference to s 13(2) of the Uniform Evidence Act was a reference to that provision as it applied before the 2007 Amendment Act. The authorities identified for the proposition that such a failure cannot be cured were R v Brooks (1998) 44 NSWLR 121 at 125 and R v BBR [2009] QCA 178; [2010] 1 Qd R 546 at [25]. However, these cases did not deal with the current provision. As correctly noted by Anderson, Williams and Clegg at [13.1], the amendment of s 13 requires that cases determined under the repealed provision should be treated with caution.
16In its earlier form, s 13(2) read:
"13 Competence: lack of capacity
...
(2) A person who because of subsection (1) is not competent to give sworn evidence is competent to give unsworn evidence if:
(a) the court is satisfied that the person understands the difference between the truth and a lie, and
(b) the court tells the person that it is important to tell the truth, and
(c) the person indicates, by responding appropriately when asked, that he or she will not tell lies in the proceeding."
17In R v Brooks, the failure to comply with paragraph (b) (being the only provision involving potential judicial instruction) was inconsequential. The Court held that where the evidence demonstrated that the child was capable of giving sworn evidence, the trial was fatally flawed in circumstances where she was not sworn. In giving separate reasons for that conclusion, Sperling J stated at 127C-D:
"I do not think there was compliance with the requirements of par (b) of s 13(2). The trial judge failed to 'tell' the complainant it was important to tell the truth. A witness who has been asked whether they know something is important has not been told it is important. The distinction is significant. The policy I discern behind the provision is that the authority of the court is to be brought to bear on the witness by means of an instruction. Nothing less will do."
18The principal judgment in Brooks was given by Grove J, who expressed, obiter, a different view concerning the requirement of s 13(2)(b), at 126E-F:
"I am unable to agree that nothing less than some form of judicial instruction is necessary. I would construe the obligation cast on the court by the provision as to convey the information that it is important to tell the truth; if the authority of the court was being called in aid the obligation could be phrased as directing the person to tell the truth. The latter could in isolation amount to an empty ritual. The conveyance of information that it is important to tell the truth is coordinated with s 13(2)(c) where the person to whom the information is conveyed is to respond by appropriate assurance that he or she will not tell lies in the proceeding. The effect is to be derived from the combined operation of both provisions. I would understand the use of 'tells' in s 13(2)(b) in the sense of making known and I see no warrant for adding to the meaning a bringing to bear of authority or some instructive character."
19Priestley JA agreed with Grove J, expressly including his "addendum concerning what is required by s 13(2)(b)": at 122D. However, the reasoning of Grove J in reaching a conclusion contrary to that of Sperling J rested heavily on the coincidence of paragraphs (b) and (c). That provided a powerful reason for the conclusion reached. Two changes have now been made in s 13, relevant for present purposes. First, sub-s (2) having been recast into sub-ss (4) and (5), there is no equivalent to the old paragraph (c), requiring a response from the prospective witness. Secondly, the idea of a condition of competence, rather than a condition of admissibility, is reinforced by the fact that competence to give unsworn evidence is said, in sub-s (4), to be "subject to sub-s (5)" and in sub-s (5) competence is said to arise "if" the elements in pars (a), (b) and (c) have been "told" to the prospective witness.
20Sections 9, 9A and 9B of the Evidence Act 1977 (Qld), as considered by the Court of Appeal in R v BBR, were different from both the Victorian and the Uniform Evidence Acts. Section 9B(3) required that, if a witness were competent to give evidence, but not on oath, "the court must explain to the [witness] the duty of speaking the truth". In circumstances where the trial judge failed to give such an explanation, the Court (Chesterman JA, Keane JA and Ann Lyons J agreeing) concluded that the failure "vitiated the trial process because the statutory condition to the reception of the child's evidence had not been satisfied": at [18]. Chesterman JA referred to Brooks at 125-126, concluding that a witness was not entitled to give unsworn evidence unless incapable of understanding the obligation to give truthful evidence and noting the finding that "before such unsworn evidence can be put before a court the requirements of s 13(2)(b) and s 13(2)(c) must be fulfilled". There was no reference to the subsequent remarks as to the nature of compliance with those provisions. Chesterman JA concluded at [25]:
"The judgments in Brooks stand as authority for two propositions. Both are relevant to this appeal but it was only the second which figured in the appellant's submissions. That proposition is that where a statute permits the giving of unsworn testimony on certain conditions those conditions must be satisfied before the evidence can be given. Where a condition is that the judge give an explanation or admonition of some kind to the witness the explanation or admonition must be given."
21R v Starrett [2002] SASC 175; 82 SASR 115 dealt with s 9 of the Evidence Act 1929 (SA), which, with a slightly different structure, was to similar effect as s 13(2) prior to the 2007 Amendment Act. Doyle CJ stated:
"[23] But s 9(2)(a)(ii) requires that the Judge 'tells the person that it is important to tell the truth.' The Judge did not do this. ... There are obvious reasons why Parliament has required that the Judge tell the witness that it is important to tell the truth, and that the witness indicate to the Judge that the witness will tell the truth.
...
[28] Such authority as there is suggests ... that this is an irregularity that gives rise to a miscarriage of justice. The trial was not conducted according to law. The appellant was entitled to such a trial. The departure from the requirements of the law is not a trifling one, nor is it a departure on a matter that can be regarded as a mere matter of form."
22Section 13(5)(c) does not impose an obligation to give instruction in a particular form, but to a particular effect. There is room for differences of opinion as to whether a particular instruction is sufficient in respect of a specific witness. Although the context differs from that where a challenge is made to the instructions given to the jury, the possibility that error might be remedied by a timely objection is present in both circumstances. It might seem undesirable if, as a matter of principle, r 4 of the Criminal Appeal Rules (requiring leave to raise a point to which objection was not taken at trial) were to be treated as irrelevant. Similarly, it might be thought unfortunate if a doubt as to the adequacy of the instruction to the witness were held to be fatal to maintenance of a conviction, despite the appeal court being satisfied there had been no substantial miscarriage of justice, for the purposes of s 6(3) of the Criminal Appeal Act 1912 (NSW).
23Section 13, it should be noted, is not directly concerned with the interests of a witness of limited competence, such as a young child: it is concerned with the public interest of obtaining evidence relevant to the determination of a criminal charge. There are other provisions which protect the interests of a child witness in sexual offences such as the present, including those which provide for the recording of evidence and the absence of the child from the court room to a different place linked by closed circuit television. It is not correct to treat the operation of s 13 as involving a balance between the interests of the child witness and those of the accused: cf BBR at [38].
24Further, BBR is not itself authority for the distinction between a condition as to competence and a condition of admissibility. The failure to comply with the statutory requirement was, it was said, such as to render the evidence "not admissible": at [39]. Nor is the failure to give instruction to a prospective witness in the same category of error as a failure to swear a witness who was competent to give sworn evidence, as in Brooks.
25Given the differences in the statutory schemes, it is apparent that no authority requires this Court to conclude that a failure to comply with s 13(5) necessitates upholding the appeal. On the other hand, it is clear that the South Australian Court of Criminal Appeal in Starrett and the reasoning of the Victorian Court of Appeal in WG support such a conclusion. Similarly, in Brooks, this Court treated the liberalisation of the rules relating to the competence of witnesses as requiring careful compliance in order to avoid a miscarriage of justice.
26A critical aspect of the present provision is that, being satisfied that a child has the capacity to understand a question and give a comprehensible answer in respect of a fact, there appears to be no residual discretion to decline to allow evidence to be given unsworn, assuming the absence of capacity to understand the obligation to give truthful evidence. A further consideration to be taken into account is the removal, also by the 2007 Amendment Act, of the power of a judge to give any of the warnings with respect to evidence of a child set out in s 165A(1), although that does not preclude an appropriate warning as to the unreliability of specific evidence: s 165A(2) and (3) and s 165.
