20 The plaintiff particularly focuses upon the word 'experience' found in s 79 of the Act. In my opinion it is clear from the written report and the oral evidence of Mr Wick that he has experience in dealing with convicted criminals, escapees and drug addicts and has accordingly acquired a 'specialised knowledge' based on that experience and that such knowledge is outside the experience of ordinary persons.
21 Behavioural profiling of criminal suspects by law enforcement officials is, in my opinion, an organised body of knowledge upon which they legitimately draw in the course of their duties. This is not to raise the predictions of Mr Wicks to a science. Rather, the knowledge of the habits, probable location and likelihood of re-offending of persons who have escaped from gaol is a corpus of knowledge the community would expect of a competent law enforcement agency or officer to have and to utilise in the manner suggested by Mr Wicks, that is, the ability to track or otherwise locate an escaped prisoner.
22 Accordingly, it is my view that the opinion of the witness is 'wholly or substantially' based on that specialised knowledge. The broad construction of the provisions of s 79 of the Act seems to be supported by observations made by the Australian Law Reform Commission in Report 28: Evidence. Such report generated the relevant legislation codifying or setting out the rules of evidence in statutory form the rules of evidence in New South Wales and federally. The ALRC took the view (in the Interim Report of 1985) that:
experience can be a sounder basis for an opinion than study. Not to include special experience as a qualification would keep valuable evidence from the courts. (At para 742.)
23 Weal v Bottom (1966) 40 ALJR 436 makes it clear that evidence given by those with long experience in driving about the tendency of articulated vehicles to 'swing out' or 'drift' when going around a curve is admissible in a negligence action, despite the fact that it is not strictly 'expert' evidence, and despite the absence of any academic or technical corpus of knowledge in the field.
24 In civil cases, every consideration should favour the court having relevant material rather than rejecting it on technical grounds, providing of course that the parties are afforded procedural fairness.
25 Although mere experience without appropriate academic qualifications may be insufficient in a technical or scientific field, it seems to me that in areas of practicality and, here, in analysis of the propensity of human behaviour a person suitably experienced can express a view in the light of that experience which would be admissible in a court and of assistance to the court in determining relevant issues.
26 I am fortified in these expressions of opinion by the judgment of the Victorian Court of Criminal Appeal in R v Yildiz (1983) 11 A Crim R 115 where it was held that an interpreter of the Turkish language could be described as an 'expert' in the sense that he was able to give opinions about the attitudes of the Turkish community towards homosexuality. In that case, the witness had no specialised learning or academic qualifications, and was not an anthropologist. He gave his evidence on the basis of personal knowledge arising from actual experience.
27 In R v Barker (1988) 34 A Crim R 141 the Court of Criminal Appeal in South Australia held that the evidence of a police officer concerning commonly used paraphernalia for the smoking of cannabis was admissible. The Court took the view that it was not in any sense 'opinion' evidence but rather evidence based upon actual observations and experience and admissible as such. The trial judge had characterised the evidence as 'of expert evidence' but that was regarded by the appellate Court as a misdescription and not fatal to the conviction. King CJ (with whom Matheson and O'Loughlin JJ agreed) said at 144 that the evidence of the police officer:
…was not opinion evidence but was evidence of facts sometimes expressed in compendious form, which she had observed in the course of her experience as a police officer particularly with the drug squad.
28 This seems to be a reasonable analogy although it might be thought that in a civil case, such as this, even greater flexibility could be extended as to the admissibility of material that might assist the Court reach a just conclusion.
29 I am also fortified in this view by a judgment of the Full Court of the Federal Court of Australia in Sydneywide Distributors Pty Limited v Red Bull Australia Pty Limited [2002] FCAFC 157 applied by R.D. Nicholson J in Australian Competition and Consumer Commission v Emerald Ocean Distributors Pty Limited (Unreported, FCA, 31 July 2002). R.D. Nicholson J said:
The contents of s 79 and the dicta of Heydon [JA] and that of Gleeson CJ…were recently considered by the Full Court of this court in Sydneywide Distributors… In their joint judgment Weinberg and Dowsett JJ, after referring to the dicta of Heydon JA, stated that 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 proceeding. More commonly, once the witness's claim to expertise is made out and the relevance and admissibility of opinion evidence demonstrated, the 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…
The difficulties of applying the dicta of Heydon JA in the course of a trial were also adverted to by Branson J who described the dicta of Heydon JA as constituting a counsel of perfection. She said that in the context of an actual trial, the issue of admissibility of evidence tendered as expert opinion evidence may not be able to be addressed in the way outlined by him. This is particularly because the admissibility of evidence is ordinarily required to be made by the trial judge during the course of the trial rather than at its conclusion. Branson J referred to the fact that s 79 has changed the common law rule that the admissibility of expert opinion evidence depends on proper disclosure of the factual basis of the opinion…She also emphasised that the general discretion to refuse to admit evidence is sufficient to deal with problems that might arise in respect of an expert opinion, the basis of which is not disclosed - see s 135 of the Evidence Act 1995 (Cth) .
30 Similarly, in Clarke v Ryan (1960) 103 CLR 486 Menzies J (with whom Fullagar J agreed) said at 503:
In truth, the decision of a trial judge that a witness is qualified to give expert evidence is very much a question of fact and it is entitled to all, but no more than, the weight that a court of appeal gives to a finding of fact upon the hearing of an action. In Bratt v Western Air Lines 166 ALR 1061; 155 F (2d) 850 (1946) and the annotation thereto (at 1067), what appears to me to be the correct rule is stated as follows:
The qualification and competency of one to give opinion evidence as an expert is primarily in the discretion of the trial court, and the admission or exclusion of such testimony on the ground that the witness was or was not qualified to testify as to his opinion as an expert, will not be reviewed or reversed by the appellate court except where such discretion has been abused, as where there is absolutely no evidence that the witness had the qualifications of an expert and his opinion has been admitted as that of an expert, or where in deciding upon the question of his competency the trial court has proceeded upon erroneous legal standards.
31 In Bratt v Western Air Lines (although tthis passage was not cited by Menzies J) it was said (at 853) that:
A witness may be competent to testify as an expert although his knowledge was acquired through the medium of practical experience rather than scientific study and research.
32 Thus, in considering the tender of relevant, opinion evidence that is based upon the specialised knowledge of Mr Wick's experiences I see no reason why I must exclude the evidence.
33 To the extent that the defendant submits that the material in the evidence is merely common sense or something that a judge can determine without the benefit of evidence from an experienced witness, I take the view that such contentions do not render the assertions inadmissible.
34 Ultimately, the evidence might not greatly assist the court in the resolution of the controversy but, subject to submissions, it is possible that it will be of some utility. At one level an opinion on the propensity of a person to act in some way might be regarded as of little value, or even self-evident. However, it is possible that the court will be assisted by the experience of a long serving police officer on the point. In my opinion, these are matters more appropriate for determination in the final judgment on liability rather than on an interlocutory or evidentiary basis.
35 Counsel for the plaintiff also points to s 80(b) of the Evidence Act 1995 (NSW) which provides:
Evidence of an opinion is not inadmissible only because it is about…a matter of common knowledge.
36 In all of the circumstances I am prepared to admit the documents as tendered, subject of course to any cross examination of Mr Wicks that the defendant might appropriately engage in, and subject to argument about the weight of particular aspects of the evidence.
37 I should note that counsel for the defendant has criticised the form or mode of expression of some paragraphs of the written statement, and obviously the cogency and weight of the evidence is subject to the form and manner in which it is expressed.
38 In these circumstances I rule that the documents tendered by the plaintiff are admissible.
