Conference of experts
31 The draft minute concerning experts presently contemplates the following four orders concerning the conference of experts:
28. In the week commencing 4 June 2011, on a date to be fixed by the Native Title Registrar of the Court (Registrar), the Registrar convene a compulsory conference or conferences to be attended, in each case by the expert witnesses of a particular discipline whom any of the parties intend to call to give evidence in the proceeding, to confer with a view to identifying matters and issues about which their opinions are in agreement and about which they differ (conference of experts).
29. The conference of experts may be reconvened from time to time as considered appropriate by the Registrar and may be limited to experts of a particular discipline or disciplines.
30. Within fourteen (14) days of the conclusion of the conference of experts, the Registrar produce a report for the use of the parties and the Court identifying:
(a) the matters and issues about which the opinions of the experts are in agreement; and
(b) the matters and issues about which their opinions differ
31. Terms of reference for each conference of experts be as agreed by the Applicant and each other party who intends to call an expert who is to participate in a particular conference or, failing such agreement, determined by the Registrar having regard to Order 30 above and any draft terms of reference proposed by such party or parties and provided to the Registrar.
32 The applicant relies on several precedents for the position it advances. The first of those appropriately is contained in the reasons for the decision of Lindgren J in Wongatha in which Lindgren J referred to the conference of experts in the following terms:
404 After they had provided their reports, including their responsive reports, the experts within the same discipline, pursuant to a direction of the Court, conferred and produced a joint report on their points of agreement and disagreement (naturally, this did not apply to the one and only archaeologist called, Professor Peter Veth). Except in the case of the linguists, who conferred by telephone, a Deputy Registrar of the Court attended the conferences and assisted in production of the reports.
405 On the hearing, witnesses with the same discipline were sworn in immediate succession and occupied the witness box together. Their reports were tendered. Each witness was invited to make an opening statement of his or her position on the issues in dispute. Then there was an opportunity for the witnesses to question each other. Next each witness was invited to make a statement of his or her position in the light of what had transpired. Finally, each witness was cross-examined and re-examined in the conventional way. The greater part, by far, of each expert witness's testimony is to be found in his or her reports, cross-examination and re-examination. The utility of the joint reports was diminished because of their brevity and generality, and their relative importance was reduced because of the extensiveness of the experts' written and oral testimony.
406 I set out below the text of the joint reports. In the case of the anthropologists, the fact that not all attended the conference also reduced the value of the report. The reports are not to be read as statutes. The experts' oral testimony revealed that the generalisations expressed in them masked points of disagreement. The reports did, however, like any out-of-court statement, record what a participant had been prepared to subscribe to at the time.
407 If a participant departed from the joint report in oral testimony, the inconsistency is to be taken into account like any other inconsistency between an expert witness's sworn testimony and an out-of-court statement. It makes no difference that the conference was held, and the report prepared, pursuant to a court direction. The reports are not pleadings.
33 The report resulting from the conference was apparently received in evidence. His Honour went on to set out the report (at [411]) of this reasons. However, it appears that the conference did not have the assistance or guidance of specific propositions considered to be relevant by and of particular interest to the parties.
34 Reliance is also placed on the decision of Selway J in Gumana v Northern Territory (2005) 141 FCR 457 where his Honour said (at [173]):
I have already referred to the agreement reached between the senior anthropologists. That agreement significantly reduced the extent of the factual disputes between the parties and the time involved in hearing the witnesses. Before any pleadings were filed in these proceedings procedural orders were made for the exchange by the parties of draft anthropological reports. Orders were then made for a "hot tub" involving each senior anthropologist for each party under the supervision of the Deputy Registrar. The purpose of the "hot tub" was to enable the experts to identify the issues and principles about which they agreed or disagreed. Legal advisers were not present. The result of those discussions between the anthropologists was an agreement between them as to certain propositions. The agreement was provided to the legal advisers. That agreement was not put before me until it was referred to and adopted by Professor Morphy as part of his evidence. The propositions agreed by the anthropologists and adopted by Professor Morphy as part of his evidence are set out in Appendix 1 to these reasons.
35 It seems clear from this passage that his Honour regarded the reduction in the number of issues resulting from the conference of experts as beneficial.
36 The applicant also refers to a presentation made by M/s Caroline Edwards, then the District Registrar (Northern Territory) of the Federal Court in relation to lawyers and anthropologists in native title cases. The District Registrar made the point in Gumana (also known as the Blue Mud Bay case) that pleadings were postponed until after the conference of experts.
37 In Akiba on behalf of the Torres Strait Regional Seas Claim People v State of Queensland (QUD 6040/2001) Finn J ordered that the two reports of the conference of experts not be admitted into evidence notwithstanding that unlike the situation in Wongatha the conference involved consideration of and resulted in a report that recorded the opinions separately of each expert in relation to specific propositions considered relevant by and of particular interest to the parties. In Akiba v Queensland (No 2)(2010) 270 ALR 564 (at [129]-[133]) Finn J said:
129 In pre-trial directions I ordered that a conference of anthropological experts be convened and that a report thereof be prepared by the Native Title Registrar "for the use of the parties". The conference was held. Two reports were produced. They took the form of statements of 86 quite disparate propositions to which the experts assigned their agreement or otherwise, occasionally with brief explanatory comments. The experts signed declarations at the end of each report. The Applicant subsequently sought to tender both reports primarily for the purpose of proving the opinion of the experts on the various propositions. I made a ruling pro tem on 1 December 2008 that I would reject the tender. These are my reasons for so doing.
130 The tender was, to say the least, ambitious. As I indicated at the time of the ruling, the direction given to convene a conference of experts was not made under O 34A(3)(2) of the Federal Court Rules. I did not seek and did not anticipate that I would be provided with reports that would be of use to the Court. Having examined them on the voir dire, my expectation has been confirmed in relation to matters of critical significance in the proceedings. Secondly, in giving the direction, the issue did arise as to what possibly might be the subsequent evidentiary use of the reports. I indicated at the time that the reports as such would be without evidentiary significance. This is not to say that material provided to the experts for the conference may not have been able to be used consistent with the provisions of the Evidence Act in cross-examination etc. It was for this reason that I did not, at the request of the parties, make an order which would have ensured the entire confidentiality of the materials used at the conference and in particular each expert's draft report.
131 My purpose in having the conference was to facilitate the development of the experts' opinions through a process of interchange between them. This is a familiar scholarly process in the social sciences. The conference was intended to inform the experts of the views of their colleagues and hence enhance the sharpness of their final reports. It equally was intended that it assist them in ascertaining what were and were not the matters in issue between them. It was not in any way intended to be a conference which would lead to the production of a document for the court containing opinions of the experts. If I had in mind such a purpose, the directions I would have given would have been of a totally different character. My intention was clearly understood by the State and the Commonwealth. Such appears not to have been the case with the Applicant for whatever reason. This is unfortunate but it in no way affects my view on the admissibility of the document.
132 I have very little doubt that the manner of participation of the scholars concerned would have been affected in varying degrees by the basis upon which the conference was intended to be held. The Applicant sought to avoid the obvious consequence of what informed my giving the conference direction, by reliance upon a document subsequently agreed by the legal advisers which it is said carried the matter beyond what I might have envisaged. I do not accept the agreement (which has been tendered for present purposes) had that effect and clearly it was not seen to do so by the Respondents. It contained no agreement as to the potential use of the report, although a clause in it reserved the position of the parties. That agreement would always of course be subject to my ruling under the Evidence Act insofar as admissibility of reports in whole or in part were concerned and, in this respect, I would refer to s 135 in particular.
133 The Applicant also contended that, not to allow the reports to be admitted, would deprive them and the Court of the benefit of what is said to be a considerable level of agreement between the experts on issues they were asked to consider by the various parties at the conference. The experts' final reports indicate, in my view, the utility of the process engaged in at the conference. Moreover, there was simply no reason to assume that the issues upon which there may have been agreement would in fact be found in any way to be relevant in the proceedings. Even if the reports might be said to have had probative value, I ruled them inadmissible under s 135, given the circumstances of their provenance and the reliance thereon by the State and the Commonwealth.
38 A conference of experts and report were also ordered by North J in VID6004/1998.
39 Of the orders set out above, Orders 28 and 31 have been agreed but there is a substantial difference between the State and the applicant in relation to the nature and purpose of the conference of experts which is reflected in the respective drafting proposed for Orders 29 and 30.
40 The State's proposal for Orders 29 and 30 is as follows:
29. The conference or conferences of experts shall not be a convened under Federal Court Rules O34A r3(2) but shall be intended to promote the informal development of experts opinions through interchange between them. A conference may be reconvened from time to time as considered appropriate by the Registrar and may be limited to experts of a particular discipline or disciplines.
30. Within fourteen (14) days of the conclusion of each conference of experts, the Registrar shall produce a report for the use and guidance of the experts in finalising their reports. Any such report of the Registrar:
(a) shall identify, the matters and issues about which, to the perception of the Registrar, based on the proceedings at the particular conference of experts the opinions of the participating experts are in agreement;
(b) shall identify, the matters and issues about which, to the perception of the Registrar, based on the proceedings at the particular conference of experts, the opinions of the participating experts differ;
(c) in the interests of promoting frank discussion amongst the experts attending such a conference [absent agreement or subsequent order or further application by any party]:
(i) shall not be received as evidence in the proceedings,
(ii) shall not be referred to in the final reports of experts (which final reports may however address the substance of any issue identified at a conference of experts by the Registrar),
(iii) shall not be put to an expert on cross examination, and,
(iv) shall not directly or indirectly be made the subject of a notice to admit facts.
41 As to this, the applicant expresses concern as to the 'extreme limitations, vagueness of purpose and the absence of appropriate guidance to the experts' which, it says, is suggested by the first sentence of the State's draft for Order 29.
42 The State considers it prudent to guard against a misunderstanding as to the approach to be taken in this conference and seeks to ensure that the free exchange of ideas between experts is encouraged in the conference before final reports are filed and served. The State is anxious that the conferences should not become or be taken as an opportunity to lay groundwork work for cross-examination, the securing of admissions or otherwise gaining procedural advantage. To that end, the proposal is to make it clear that the report of the Registrar is not to be used by the Court but is to guide the experts in finalising their reports.
43 In my view, the State's position is appropriate and accords with the reasoning of Finn J in Akiba. I would therefore make orders in accordance with the States draft Order 29 and Order 30. This would not preclude the parties developing between themselves a different regime if such agreement can be reached. Nor would it preclude the position being reviewed on a later motion. To that end, I have added 'absent agreement or subsequent order or further application by any party' to the preamble to the State's proposed Order 30(c).
