The Previous Legislation
28 Before the new version of section 13 commenced, the text of section 13 was:
"13(1) A person who is incapable of understanding that, in giving evidence, he or she is under an obligation to give truthful evidence is not competent to give sworn evidence.
(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.
(3) A person who is incapable of giving a rational reply to a question about a fact is not competent to give evidence about the fact, but may be competent to give evidence about other facts.
(4) A person is not competent to give evidence about a fact if:
(a) the person is incapable of hearing or understanding, or of communicating a reply to, a question about the fact, and
(b) that incapacity cannot be overcome.
(5) It is presumed, unless the contrary is proved, that a person is not incompetent because of this section.
(6) Evidence that has been given by a witness does not become inadmissible merely because, before the witness finishes giving evidence, he or she dies or ceases to be competent to give evidence.
(7) For the purpose of determining a question arising under this section, the court may inform itself as it thinks fit."
29 Sections 12 and 21 have had no substantive changes since the Evidence Act was enacted. (Section 21 has had a minor change in consequence of the alteration of another section.)
30 In R v Brooks (1998) 44 NSWLR 121 a complainant in a child sexual assault case, C, had been permitted to give unsworn evidence, when the presumption of competency arising from section 13(5) in its then form had not been displaced. This Court held that there had thereby been a fundamental miscarriage in the trial, such that the conviction could not stand.
31 Grove J, at 124 said:
"It is fundamental to our system of trial that a person may not be convicted other than upon sworn evidence and, unless the material emanating from C was available to be deliberated upon by the jury pursuant to some express statutory warrant, there was an absence of evidence upon which conviction of the appellant could be sustained."
32 Grove J continued, at 125:
"Although it is obvious that the jury was convinced of the truth of what C had to say and the reasons for upholding the appeal may be regarded as highly technical, the consequence that the trial was not held according to law must result in the convictions being set aside."
33 Grove J also said, at 126:
"It is apparent that neither counsel appearing at trial drew his Honour's attention to the situation as it has now been identified. The consequence of the erroneous procedure was to render the articulations of C before the jury unavailable as an evidential resource and leave to argue the ground pursuant to r 4 of the Criminal Appeal Rules 1986 could not appropriately be refused. In the same vein, the proviso to s 6 of the Criminal Appeal Act 1912 could not be applied as a conviction based upon an absence of evidence could not be categorised as involving no substantial miscarriage of justice."
34 Priestley JA agreed with Grove J. Priestley JA, at 122, explained why the taking of the evidence unsworn was a fundamental defect:
"In the High Court, in Bulejcik v The Queen (1996) 185 CLR 375, McHugh J and Gummow J observed (at 408) that: 'It is fundamental to the common law system of criminal justice that a person can only be convicted on admissible evidence given in open court.'
Thus, it became basic to this appeal that this Court should decide whether what the complainant told the jury was admissible evidence. That it was not is shown by cases extending over a very long period, until today, despite some questioning of the position in the Eleventh Report of the Criminal Law Revision Committee in England, on Evidence (1972) at 163 and following. Cases in which the position is either stated or clearly taken as correct are: Lord Shaftsbury v Lord Digby (1676) Freeman 422; 89 ER 314; R v Marsham; Ex parte Pethick Lawrence [1912] 2 KB 362; R v Brown [1977] Qd R 220; R v Sossi [1986] WAR 163 at 167; Attorney General's Reference (No 2 of 1987) (1987) 46 SASR 275.
It is thus well-established that 'evidence' not given under oath or under some lawful alternative sanction is not admissible evidence, and it follows that the trial in the present case in which non evidence of that kind played a material part was not a trial according to law."
35 R v Brooks was decided on 14 July 1998. A month earlier, a differently constituted Court of Criminal Appeal had decided R v Fitzsimmons (NSWCCA, 15 June 1998, unreported). In it, the complainant in a charge of sexual assault against a child had given evidence unsworn, without the procedures of the then section 13 being gone through before the complainant was permitted to do so. Newman J, with whom Studdert J agreed, said, at 8:
"In the instant case the appellant actually had the benefit of reference being made to the fact that K's evidence was unsworn. I am of the view that the procedure adopted was in fact defective and that an error occurred. However, if this were the only matter of error in the case I would be of the view that the proviso to s 6 of the Criminal Appeal Act should be applied."
36 As it happened, the court found other deficiencies in the trial that resulted in the conviction being quashed. While Simpson J agreed with that order, her Honour said, at 11:
"I agree that the procedure adopted in relation to the taking of evidence of the complainant was defective, and constituted error of law. I am not persuaded that, were there no other successful ground of appeal, that the defect was such as could be overcome by the application of the proviso of s 6 of the Criminal Appeal Act 1912 but, in the light of the proposed result in relation to the third ground of appeal, it is unnecessary further to consider this question."
37 The decision in R v Brooks being the later decision, and being one in which the effect of failure to comply with the requirements of section 13 before receiving unsworn evidence was the reason why the conviction was set aside, this Court should now follow R v Brooks unless persuaded it was wrong. Not only am I not persuaded it is wrong, in my view it was correctly decided.
38 Further, R v Brooks has since been applied in R v JTB [2003] NSWCCA 295, in which a conviction based on the unsworn statements in court of an eight year old was set aside, when no attempt had been made to decide whether the presumption of competence to give evidence had been displaced, or whether the presumption of competence to give sworn evidence had been displaced. Grove J, at [12]-[15] said that there was no lawful sanction permitting her to give evidence in the way she did, in consequence of which the trial was not held according to law, and thus the conviction had to be set aside. Hulme J said, at [20]-[23]:
"The jury clearly believed what the complainant, though not sworn or having made an affirmation, said. It is inconceivable that the taking of an oath or the making of an affirmation would have made the slightest difference to what she said. Certainly there is nothing to suggest it would have, and there is no conceivable ground for thinking that had she made an oath or taken an affirmation or had the steps envisaged by s13 been taken, the jury's verdict would have been any different.
There is, thus, much in favour of the view that no substantial miscarriage of justice has occurred and the Court should apply the proviso to s6 of the Criminal Appeal Act .
However, this Court in R v Brooks (1998) 44 NSWLR 121 has made it clear that the deficiency or defects which occurred in this case are of a nature so fundamental that the proviso should not be applied.
Though I am not sure I would have reached the same conclusion had I approached the matter de novo, I do not feel sufficiently confident of the view that what was said in Brooks is wrong to depart from it and, accordingly, I agree with the orders proposed."
