Refshauge J
Original judgment source is linked above.
1. The accused's application made on 22 April 2010 that the expert opinion evidence of Dr Helen Parker be ruled inadmissible is dismissed
2. The accused's application made on 22 April 2010 that there is no evidence to justify a conviction is dismissed.
Just that the speed limit there is 80 kilometres an hour and for a motorcycle rider going into an impact with the side of a vehicle, it's fairly catastrophic at 80 kilometres an hour.
The rider just, up in the air and just came down, hit his head on the top of the golden car.
From looking at the damage profile and the medical records, I'm not a doctor, but I've seen significant injuries on this young man, he more than likely has struck it face on. More than likely that the front of his helmet and his head into the car as he's been catapulted off his bike into the vehicle. He's then fallen, like I said, fallen to the ground.
What? I'm sorry, perhaps I missed something. What did he die of?---Well, he died - certainly clinically from the notes, he died of aspiration pneumonia.
I see. Yes, all right. I thought that was coming, but I hadn't got to it myself. And, so you say that the death from aspiration pneumonia was causally related directly to the head injury?---Yes, that's correct.
In short, if evidence tendered as expert opinion evidence is to be admissible, it must be agreed or demonstrated that there is a field of "specialised knowledge"; there must be an identified aspect of that field in which the witness demonstrates that by reason of specified training, study or experience, the witness has become an expert; the opinion proffered must be "wholly or substantially based on the witness's expert knowledge"; so far as the opinion is based on facts "observed" by the expert, they must be identified and admissibly proved by the expert, and so far as the opinion is based on "assumed" or "accepted" facts, they must be identified and proved in some other way; it must be established that the facts on which the opinion is based form a proper foundation for it; and the opinion of an expert requires demonstration or examination of the scientific or other intellectual basis of the conclusions reached: that is, the expert's evidence must explain how the field of "specialised knowledge" in which the witness is expert by reason of "training, study or experience", and on which the opinion is "wholly or substantially based", applies to the facts assumed or observed so as to produce the opinion propounded. If all these matters are not made explicit, it is not possible to be sure whether the opinion is based wholly or substantially on the expert's specialised knowledge. If the court cannot be sure of that, the evidence is strictly speaking, not admissible, and, so far as it is admissible, of diminished weight.
The approach of Heydon JA as set out above is, as it seems to me, to be understood as a counsel of perfection. As a reading of his Honour's reasons for judgment as a whole reveals, his Honour recognised that in the context of an actual trial, the issue of the admissibility of evidence tendered as expert opinion evidence may not be able to be addressed in the way outlined in the above paragraph.
The use of the phrase "strictly speaking" in the last sentence should not be overlooked. It may well be correct to say that such evidence is not strictly admissible unless it is shown to have all the qualities discussed by Heydon JA. However, many of those qualities involve questions of degree, requiring the exercise of judgment. For this reason it would be very rare indeed for a court at first instance to reach a decision as to whether tendered expert evidence satisfied all of his Honour's requirements before receiving it as evidence in the proceedings. More commonly, once the witness's claim to expertise is made out and the relevance and admissibility of opinion evidence demonstrated, such evidence is received. The various qualities described by Heydon JA are then assessed in the course of determining the weight to be given to the evidence. There will be cases in which it would be technically correct to rule, at the end of the trial, that the evidence in question was not admissible because it lacked one or other of those qualities, but there would be little utility in so doing. It would probably lead to further difficulties in the appellate process.
in the circumstances of most cases, however, a bare expression of opinion is likely to be incapable of affecting the assessment of the probability of the existence of any fact in issue in the proceedings
Evidence of the history taken by a doctor has always been admissible...as establishing the basis upon which the doctor framed the expert evidence to be given by him or her in evidence, but not (except for statements of the type now made admissible by s 72) in order to establish the truth of what was said. As a result of s 60, evidence by a doctor of the history given to him or her by the patient and upon which the doctor bases his or her expert opinion is therefore now evidence of the truth of that history. This is so whether or not the facts stated in the history were at the time of giving the history fresh in the patient's mind, whether or not the history was given in circumstances which made it highly probable that it was reliable or which made it unlikely to be a fabrication, and whether or not what was said was within the patient's personal knowledge - unless an order is made limiting the use which may be made of that evidence pursuant to s 136. All of this is very relevant to the weight to be given to the history where there is no other evidence supporting it. (Footnote omitted)
Accordingly, I find that this opinion is admissible if otherwise relevant on the principles established following Makita.
Essentially business records are prepared as internal records in the course of or for the purpose of the business. It is most unlikely that those expressing opinions in business records would attend to the requirements of s 78 of s 79, let alone with the precision required by Makita. It would not occur to the people creating those documents that they should set out to justify their opinions in the same way that an expert would do in preparing a written report for a court hearing. In those circumstances, to apply the opinion rule to business records that meet the requirements of s 69 would be substantially to undermine, if not to negate, the implementation of the policy underlying the business record provisions, asserted so forcefully by Hope JA in Albrighton (at 548 - 549) and by the Australian Law Reform Commission in its Interim Report on Evidence at [709]. Courts would be prevented from having access to substantial components of the records of businesses so as to assess them for what they are, on the ground that they do not satisfy requirements which their authors would not have regarded as relevant.
However, s 59 operates to exclude out-of-court representations of opinion as well as of fact, having regard to the decision in Ringrow. It seems plausible to say, (as ASIC submitted in AS 67) that s 59 having had that effect, the opinion rules in ss 76 to 79 operate on opinion evidence given in court.
Support for the view that the opinion rules in ss 76 to 79 are confined to evidence of opinions given by witnesses in court, leaving s 59 and its exceptions to deal with out-of-court hearsay representations of fact and opinion, may be found in ss 78 and 79, both of which appear to envisage a witness presenting evidence in which the basis of the opinion is articulated, something that is unlikely to occur when opinions are expressed in the records of a business in the course of or for the purposes of the business. This construction avoids the undermining of the business records policy. It also avoids the tension that would otherwise arise between the opinion rules in s 69(2)(b), which allows the hearsay rule to be overcome, inter alia, where a previous representation of fact or opinion was made on the basis of information directly or indirectly supplied by a person who had or might reasonably be supposed to have personal knowledge of the asserted fact. In contrast, the opinion rules require that the previous representation of opinion be based on what the person saw, heard or otherwise perceived (s 78), or that it be based on specialised knowledge (s 79). Confining the opinion rules to evidence given in court is consistent with their rationale. It is appropriate to require a witness giving an opinion in an adversary context to comply with the relatively strict requirements of s 78 or s 79, because of the risk of bias or influence, while opinions expressed in business records created for non-litigious purposes are treated as generally reliable.
I agree with ASIC that an interpretation of the opinion rules which confines them to the evidence of witnesses in court receives some support (though it is limited) from extrinsic materials concerning the enactment of the Evidence Act 1995.
The primary judge may have thought that the principles stated by Heydon JA in Makita (Australia) Pty Ltd v Sprowles [2001] NSWCA 305; (2001) 52 NSWLR 705 apply with full force to statements by experts in business records made when litigation was not in contemplation. It is far from clear that these principles apply with their full force, or at all, to out of court statements by experts in business record, even if such statements do have to meet the standard in s 79.
I certify that the preceding sixty-seven (67) numbered paragraphs are a true copy of the Reasons for Judgment herein of his Honour, Justice Refshauge.
