Discussion
27 In my opinion the conclusion that the actions of Sister Finnerty involved "grave impropriety" was not open to his Honour. It could not be doubted that the taking of blood was not authorised by law and was a serious invasion of the respondent's personal rights: see Lill v Thompson Loveday J, unreported, NSWSC 30 January 1989; (1989) 8 MVR 300 at 306 per Loveday J.
28 However, s 138 requires consideration not only of the effect of the action but also the motivation of the person who carries out that action. Section 138 operates in relation to evidence that was obtained improperly or in contravention of a relevant law or in consequence of an impropriety (subs (1)). Subs (3) directs the court to consider the gravity of the impropriety or contravention s 138(3)(d) and whether the impropriety or contravention was deliberate or reckless s 138(3)(e).
29 The respondent was present in the Emergency Department of the hospital following a motor vehicle accident with obvious signs of head injury. The Sister acted in the belief that he was a patient and that she was obliged to take the blood sample. Her actions would have been lawful if, as she believed, he had attended at the hospital for treatment or examination. Notwithstanding that the taking of blood is a significant invasion of a person's privacy, the legislature has provided that an individual's right to privacy cannot prevail over the taking of a blood samples from accident patients. The public interest in ensuring that persons do not drive when affected by alcohol has been judged by the legislature to be greater than an individual's right to privacy. Where, as in this case the blood sample was obtained by the sister, in the innocent, but mistaken belief, that she was obliged to obtain it, only a minimal level of impropriety was involved.
30 Apart from this difficulty, in my view, the trial judge's consideration of the elements which s 138 requires to be balanced was not correct. His Honour was concerned that the admission of the evidence of the blood sample would bring considerable prejudice to the respondent. His Honour had in mind that the evidence would be likely to lead to the conclusion, as was discussed during the course of the pre-trial hearing, that the respondent would have no alternative but to plead guilty to the relevant offence. Admission of the evidence may be conclusive proof of the fact that the respondent was under the influence of intoxicating liquor at the time of the accident (s 52AA(1)). His Honour concluded that this prejudice, which was personal to the respondent, together with the level of impropriety which he identified meant that the evidence should be excluded.
31 In my view the approach which his Honour took was not appropriate. As Howie J made plain in R v EM (2003) NSWCCA 374 at [74]-[78] s 138 is concerned with balancing public interests. The prejudice to the individual accused, which to varying degrees must be present in every case, will rarely be material. It may be of concern if the means by which the evidence was obtained has the consequence that an accused cannot effectively respond to it. There may be other personal considerations in a particular case. However, the fundamental concern of the section is to ensure that, if the law has been breached, or some other impropriety has been involved in obtaining the evidence, this is balanced against the public interest in successfully prosecuting alleged offenders. The competing interests are obedience to the law in the gathering of evidence and enforcement of the law in respect of offenders. In R v EM Howie J said at [74]:
"The discretion under s 138 is similar to that which was described in Swaffield as the public policy discretion at common law. Of course, there is a significant difference between the discretion under s 138 and that at common law: the section requires that the Crown persuade the court to admit evidence that was improperly or unlawfully obtained. But just as at common law, the public policy discretion was distinct and separate from the unfairness discretion, so the discretion to admit evidence under s 138 is a distinct and separate discretion from that arising under s 90. The two discretions may overlap but they are not synonymous. Section 138 is not, in its terms at least, concerned with the court ensuring a fair trial for the accused. Certainly that is not a paramount consideration when exercising the discretion. The discretion exercised under s 138(1) seeks to balance two competing public interests, neither of which directly involves securing a fair trial for the accused."
32 There can be no doubt that, if the Crown can prove the taking of the blood sample, analysis of that sample showing a reading in excess of 0.15 and evidence that this reading may prove the blood alcohol level of the respondent at the time of the accident, the evidence will have significant probative value in this trial. The evidence may be the foundation of the Crown case.
33 However, the offence with which the respondent is charged is serious (see s 138(3)(c)), involving as it does the loss of life of another. It carries a maximum prison term of ten years. The measure of the public interest in the conviction of an offender is greater in relation to serious crimes: R v Dalley (2002) 132 A Crim R 169 at [3], [7].
34 In these circumstances, in my view, the balance which s 138 requires to be struck inevitably leads to the conclusion that, if otherwise admissible, evidence of the blood alcohol level of the respondent at the time of the accident obtained from the blood sample taken by Sister Finnerty should be admitted into evidence.
35 This case is to be distinguished from a situation where evidence is obtained by police in knowing breach of the law or, where they may be reckless as to whether or not it has been lawfully obtained. Where the breach of the law is innocent, and the alleged offence serious there must be powerful countervailing considerations before the evidence should be rejected. The fact that the evidence is of high probative value will weigh in favour of its admission.
36 For these reasons, in my opinion, insofar as the Crown appeals an interlocutory ruling of his Honour rejecting evidence of the blood sample and its alcohol content pursuant to s 138 of the Evidence Act, the Crown appeal should be upheld. In coming to my conclusion I have assumed that the evidence, if admitted would be probative of the blood alcohol level of the respondent at the relevant time. It will be a matter for the trial judge to consider whether, for reasons other than the improper taking of the blood sample, the evidence should be admitted.
37 For these reasons, in my opinion, the appropriate orders are:
