ground C: appointment of court expert
15 There is no challenge to the validity of r 15.09 of the Federal Magistrates Court Rules ('the Rules') which relevantly provides:
'15.09 (1) The Court may, at the request of a party or of its own motion:
(a) appoint an expert as court expert to inquire into and report on a question arising in the proceeding; and
(b) …
(c) give … directions, including to extend or supplement the inquiry or report.
(2) If possible, the court expert should be a person agreed upon between the parties.'
16 Rules 15.10, 15.11 and 15.12 of the Rules relevantly provide:
'15.10(1) The court expert must give the report to the Registrar together with the number of copies the Registrar directs.
(2) The Registrar must send a copy of the report to each party.
(3) The Court may:
(a) receive the report in evidence; or
(b) allow the examination of the court expert; or
(c) give other directions as to the use of the report.
(4) A party wishing to cross-examine the court expert:
(a) must arrange for the attendance of the court expert; and
(b) may issue a subpoena requiring his or her attendance; and
(c) unless the Court otherwise directs, must pay the reasonable expenses of the attendance.
15.11 Unless the Court otherwise directs, the parties are jointly liable to pay the reasonable remuneration and expenses of the court expert for preparing a report.
15.12 If a court expert has made a report on a question, a party may adduce evidence of another expert on the question with the leave of the court.'
17 The above rules are in substantially the same form as O 34 of the Federal Court Rules ('the FCRs'). They may be assumed to have been modelled, at least in part, on O 34 of the FCRs. Guidance on the proper approach to the exercise of the power to appoint a court expert pursuant to r 15.09 of the Rules can thus be obtained from authorities concerning O 34 and comparable rules of other courts. It is also helpful, in my view, to give some consideration to the history that lies behind O 34 of the FCRs and similar rules.
18 It has been said the common law has recognised the power and right of a judge to call an expert witness since at least the fourteenth century when, in an appeal of mayhem in 1345, it is reported that surgeons were summoned to say if a wound was fresh (Anon. Lib. Ass., 28, pl. 5, cited in J Basten, 'The court expert in civil trials - a comparative appraisal', Modern Law Review, vol 40, 1977, p 174 at p 175; see also I Freckleton and H Selby, Expert evidence, 3rd edn, Lawbook Co, 2005, p 690).
19 However, whether because of what Basten JA (as the learned author of the above article may now be referred) described as the 'emasculating' provisions of rules of court that authorised the appointment of court experts 'on the application of any party', or for some other reason, it became accepted in the United Kingdom and Australia in the early twentieth century that a judge could not call a witness not called by either party over the opposition of a party (see Justice I Sheppard, 'Court witnesses - a desirable or undesirable encroachment on the adversary system', Australian Law Journal, vol 56, 1982, p 234). The position may have been less strict in equity suits where the paternity or wardship of children was in issue (see, for example, Re S (infants) [1967] 1 All ER 202 and In Re L (An Infant) [1967] 3 WLR 1149).
20 The dangers historically thought to attend the appointment of a court expert included that a perception might arise that the judge had abandoned the traditional judicial role under the common law system which is to resolve the dispute between the parties on the basis of the evidence called by the parties. This traditional approach is well illustrated by the observation of Lord Denning in Jones v National Coal Board [1957] 2 QB 55 at 64:
'The judge's part in all this is to hearken to the evidence, only himself asking questions of witnesses when it is necessary to clear up any point that has been overlooked or left obscure; to see that the advocates behave themselves seemly and keep to the rules laid down by law; to exclude irrelevancies and discourage repetition; to make sure by wise intervention that he follows the points that the advocates are making and can assess their worth; and at the end to make up his mind where the truth lies. If he goes beyond this, he drops the mantle of a judge and assumes the robe of an advocate; and the change does not become him well.'
21 A further danger thought to attend the appointment of a court expert was that the court might attach undue weight to the report of the court expert should a party seek to contradict its contents (see In Re Saxton Dec'd [1962] 1 WLR 968 at 972).
22 Modern amendments to rules of court which authorise the appointment of a court expert on the application of a party or on the court's own motion reflect a change in philosophy as to the proper role of courts in the management of litigation. It is now widely accepted that courts carry responsibility to assist in the just, efficient and cost‑effective resolution of disputes giving rise to litigation. Indeed, the Australian Law Reform Commission in its Report No 89 'Managing Justice: A Review of the Federal Civil Justice System' stated at 1.14:
'One of the major thrusts of this report is that our civil justice system works best when judicial officers take an active role in managing proceedings from an early stage.' (emphasis in original)
23 It is presumably for the above reason that, as the authorities reveal, orders made under rules of court for the appointment of a court expert have generally been made well before trial in the course of the case management of the proceeding. Indeed, Basten JA observed in the article referred to in [18] above at p 185:
'No doubt a judge would be unwilling to make an order at a very late stage, or during the hearing as this would lead to delays and would fail to save any expenditure on presentation of partisan evidence.'
24 In Newark Pty Ltd v Civil & Civic Pty Ltd (1987) 75 ALR 350 Pincus J granted an application made after the close of pleadings for the appointment of a court expert under O 34 of the FCRs. The applicant in that case was in liquidation. His Honour at 351 noted that if the application proved unsuccessful the whole of the amount available for the payment of costs and creditors might be swallowed up in pursuing the application. His Honour went on to observe:
'It is suggested that courts should be cautious in applying rules of this sort. There does not seem to me, however, to be any special need occasion for caution. An architect … is available to do the report for a fee of $600 - ie about one-half of 1 per cent of the anticipated costs of the whole case. It is true that, as counsel for the respondent contend, the expert's report may not resolve the matter. The case might still continue. On the other hand, even if that occurs, the report is admissible in evidence O 34, r 3(3)) and may be expected to assist the court to resolve the issues. It is, of course, possible that the report will assist towards settlement of the case, a matter which has apparently been discussed between the parties.
Looking at the matter more broadly, the case seems one peculiarly suited to treatment of this sort. The amount in issue is very much less than the expected cost of the litigation and a competent person is available to look into the central questions requiring expert resolution, on behalf of the court. Experience suggests that too often expert witnesses display a degree of partiality, whereas the court-appointed expert may be expected to be indifferent as to the result of the case.'
25 In Britten v State of Western Australia [2001] FCA 1256 Gray J appointed an anthropologist as a court expert to inquire into and report upon the identity of persons claimed by an illiterate applicant to be the holders of native title in certain land. This step was taken by his Honour on his own initiative shortly after the matter came into his Honour's docket. His Honour was faced with a legislative requirement to deal with the claim of the applicant together with another claim that covered in part the same land. For this reason it was necessary for the Court to know the identities of all those who were said to be the holders of native title in the land in question. His Honour concluded that it would be undesirable in the circumstances to require an unrepresented party who did not read or write to provide a list of the names of the persons that she claimed held native title to the land.
26 In Trade Practices Commission v Arnotts Limited (1989) 21 FCR 318 Beaumont J noted that an order had earlier been made by consent in that case appointing a court expert to report on whether, in effect, certain survey material prepared by a research centre provided a sound basis for the drawing of conclusions as to the views of the population of Australia. Similarly in First Netcom Pty Ltd v Telstra Corporation Ltd (2000) 101 FCR 77 at [10] the Full Court noted that:
'…in the course of general case management in relation to the proceeding, the primary judge appointed Mr Roger Amos pursuant to O 34, r 2(1)(a) of the Federal Court Rules 1979 (Cth) to inquire into, and to prepare a report to the Court concerning, the questions to be determined in the proceeding.'
27 In Gale v New South Wales Minister for Land & Water Conservation (2001) 6(4) AILR 66; [2001] FCA 1652 Madgwick J refused an application to appoint a court appointed expert under O 34 r 2 of the FCRs in circumstances in which expert evidence had already been filed by both parties to the proceeding but the expert evidence filed on behalf of the applicant had been shown to be deficient and the applicant was unable to fund the provision of additional expert evidence. Madgwick J at [5] observed:
'Order 34 r 2 does not authorise the Court to act for the purpose of assisting any particular party to a proceeding against others in the gathering or presentation of evidence, although unintended or incidental assistance to a party may be the consequence of the Court's utilisation of that power. The touchstone is the interests of justice.'
28 Additional guidance on the proper approach to the exercise of the power to appoint a court expert may be gleaned from the judgment of the Court of Appeal in Abbey National Mortgages plc v Key Surveyors Nationwide Ltd [1996] 3 All ER 184. The primary judge in that case had, in reliance on O 40 of the Rules of the Supreme Court, appointed a court valuation expert. Order 40 authorised the Court, in any matter in which any question for an expert witness arose, on the application of any party to appoint an independent expert. At 187‑188 the Court of Appeal stated:
'In submitting that the judge had no power under the order to make the order he did for appointment of a court expert, Mr Leighton Williams advanced four main submissions. These were: (1) that the order was only applicable to questions of a scientific or technical kind; (2) that it was only appropriate to appoint an expert under the order to give an opinion on a subsidiary question, and not on the major issue which the court had to resolve; (3) that a court expert appointed in present circumstances would not be an "expert" within the meaning of the order, since he would necessarily lack personal knowledge or experience of market conditions and values in many of the areas upon which he would have to report; and (4) that the court expert was in truth being invited to give an opinion on the answer to 51 questions and not to one, so that the parties were each entitled under r 6 to call a witness to give evidence on each of those 51 questions.
As to the first of these contentions, we strongly suspect that the draftsman of the order did indeed envisage its use to resolve questions of a scientific or technical kind. The draftsman may also have envisaged the use of the order to resolve subsidiary questions and not the major issues in the case. We do not, however, find anything in the language of the order which restricts its use to cases in which the assistance of a court expert is sought tor solve questions which are scientific or technical or subsidiary. Times change and procedure develops. We do not think that the terms of the order forbid an appointment such as the judge made if it was otherwise appropriate. We do not accept the third contention, that a court expert so appointed would not be "expert". Rule 1(1) envisages that a court expert may be appointed to inquire and report. He may therefore have to qualify himself to give expert evidence. What is required is that the expert, when so qualified, should possess the expertise of his professional calling. So far as the fourth convention, based on r 6, is concerned, we think that "the question reported on by the Court expert" must be read to mean "the question or questions". If more than one question is asked of the court expert, it does not in our view follow that each party is entitled to call one expert on each of the questions so asked.'
29 Notwithstanding the limited case law on the circumstances in which the discretionary power of a court to appoint a court expert should be exercised, the following broad principles can, I consider, be deduced from the authorities:
(1) the power to appoint a court expert is part of the armoury made available to courts for the purpose of ensuring the just, efficient and cost‑effective management of litigation;
(2) the power to appoint a court expert is to be broadly understood and is not available to be exercised only where litigation calls for expert evidence of a scientific or technical kind;
(3) a court expert may be appointed to express an opinion on the major issue to be decided in the litigation;
(4) generally speaking, the correct approach will be to regard the appointment of a court expert as the first step, but not necessarily the only step, in the obtaining of expert evidence on a particular issue;
(5) ordinarily the appropriate time for the exercise of the power is well before trial so that the parties have adequate time to give consideration to the report of the court expert and to make decisions on whether they wish to challenge any part of that report;
(6) the power to appoint a court expert is not ordinarily to be exercise for the purpose of assisting an impecunious party to gather evidence - although the appointment of a court expert may in fact provide such assistance.
30 As the Court of Appeal observed in Abbey National Mortgages plc v Key Surveyors Nationwide Ltd at 185, it is not of itself an argument against an order concerning expert evidence that the form of the order is novel, even bold and innovatory. Their Lordships pointed out, with reference to the United Kingdom, at 185‑186:
'There can be no purpose in commissioning expensive and far‑reaching reports on civil procedure if lessons which emerge are not heeded. Exhortations to trial judges to be interventionist and managerial would be futile if every managerial initiative by a trial judge were to be condemned as an unwarranted departure from orthodoxy. It would be most unfortunate if the Court of Appeal were to block reasonable attempts to mitigate the defects of established practice. At the same time, of course, both trial judge and [the] Court of Appeal must be constantly alert to the paramount requirements of justice; justice to the plaintiff and justice to the defendant. To expedite the just despatch of cases is one thing; merely to expedite the despatch of cases is quite another. The right of both parties to a fair trial of the issues between them cannot be compromised.'
