24 As identified in the Council's submission at par 14, the obligation to accord procedural fairness in courts and tribunals is significant, as reflected in the breadth of cases referred to by the Council in its submissions, summarised at par 14. The failure to afford procedural fairness is an error of law. It is well settled that the principles of natural justice including the requirement to accord procedural fairness must be observed by commissioners determining Class 1 proceedings, see Carstens at 45. The focus of this ground of appeal is the extent the requirement to accord procedural fairness required the right to cross-examine to be afforded to the Council during the hearing. There are numerous authorities relied on by the parties which deal with the right to cross-examine in the context of procedural fairness. A review of these authorities makes clear that the particular statutory framework and circumstances determine what procedural fairness is required.
25 The authorities relied on by the Applicant to suggest the scope of procedural fairness in relation to cross-examination in these Class 1 proceedings was criticised by the Council because those cases dealt with proceedings of a different type. Bushell concerned a planning inquiry relating to two motorway schemes under the UK legislation the outcome of which was a recommendation to the relevant Minister. The inspector in charge refused leave to cross-examine a witness to the relevant Department who gave evidence regarding the accuracy of traffic predictions. The House of Lords held (Lord Edmund-Davies dissenting) there was no denial of natural justice in so doing. The inquiry was unlike court proceedings, being more inquisitorial in nature and resulting in recommendations being made which had no legally binding effect. Re King concerned whether cross examination should have been allowed before a planning panel appointed under Victorian legislation to inquire into objections to a draft planning instrument. The panel reported to the relevant planning authority with its findings and recommendations. Southwell J in the Supreme Court of Victoria held there was no requirement under the rules of natural justice to allow cross-examination of a witness whose evidence may be against the party. Neither decision concerned court proceedings so that the approach is not directly relevant to these Class 1 proceedings.
26 The Council sought to emphasise the adversarial nature of Class 1 proceedings, as confirmed by the Court of Appeal in Segal, to submit, I infer, that there is an entitlement to cross-examine. In this case that was said to arise particularly because of par 48(d) of the Practice Note. To that end, the Council relied on Hill v Green (1999) 48 NSWLR 161 at 148 to emphasise the importance of the right to cross-examination. That case concerned an inquiry procedure into the alleged misconduct of a teacher under the relevant regulation dealing with disciplining of teachers. The statements of Fitzgerald JA that a respondent was entitled to confront and cross-examine his accuser are obiter. Reliance is also placed on Spender J in Ramsay as set out at 16 which emphasises the requirement to challenge evidence adverse to the case a party wishes to present. The statutory framework and subject matter in both cases is markedly different to Class 1 appeals in this Court. I am here dealing with whether there should be cross-examination of a single expert witness in a planning appeal, albeit in a court hearing, where that expert owes a duty to carry out his duties in accordance with the Expert Witness Code of Conduct.
27 GPI Leisure Corp Ltd v Herdsman Investments Pty Ltd (No 3) (1990) 20 NSWLR 15 contains a helpful review by Young J of relevant authorities on the question of the right of more than one counsel to cross-examine a witness. He concluded at 22 that there is only a "right" to a fair trial and the trial judge has discretion about the cross examination of witnesses. His comments are directed to the circumstances where there are multiple parties seeking to cross-examine rather than just one.
28 A review of these authorities does not support the Council's submission that there is a right to cross-examination arising in Class 1 proceedings solely on the basis that par 48 of the Practice Note suggests that this approach is open as an alternative to calling an additional expert witness. Reliance on Segal because that case confirmed the adversarial nature of Class 1 proceedings does not suggest a greater entitlement to cross-examination than existed up to the institution of the Practice Note. The Practice Note provides procedural guidance to the parties on how an appeal should proceed, it does not found a substantive right.
29 Further, leave is required to be sought from the Court in order to cross-examine any witness in Class 1 proceedings under the Court Rules, Pt 13 r 24 which provides:
At the hearing, except with leave of the Court, the following requirements shall apply:
. . .
(d) no oral expert testimony (including cross-examination) of any expert shall be allowed.
If the Council's submissions were correct, advising the Court that reliance was placed on par 48 of the Practice Note would mean that an application to cross-examine would have to be granted and the Court would have no discretion to refuse it. As identified by the Applicant's submissions at par 21, if there was a legitimate expectation that there would be cross-examination of the single expert based on par 48 that expectation does not confer an entitlement that the application must be granted.
30 As stated above, whether the requirements of procedural fairness demand that cross-examination should have been allowed depend on the circumstances and the statutory framework. The various cases identified by the parties and set out at par 25-27 demonstrate the wide variety of circumstances in which these have been considered. The particular circumstances of this case must be considered in light of the Court Act, Rules and procedures. In Campbelltown City Council v Toth (2004) LGERA 336 McClellan J held it was the obligation of the court to use court resources to ensure prompt and efficient disposition of matters. An overriding obligation is that parties must be provided with a fair hearing. That includes an opportunity to put before the court evidence or submissions dealing with an issue that could be determined adversely to a party. The judgment referred briefly to the decision of a commissioner not to allow cross-examination at [32] and confirmed that decision in the circumstances of that case. Most of the judgment concerned another issue, the refusal by a commissioner of an application for an adjournment in order to allow further evidence to be called challenging another expert's evidence. The expert evidence which the party sought to challenge unsuccessfully was relied on by the commissioner in his ultimate decision to refuse a particular development application. McClellan J held that there had been a denial of procedural fairness by the commissioner in that circumstance.
31 It is necessary to consider the particular circumstances of this case to determine if the refusal to allow cross-examination did result in procedural unfairness to the Council. While stating that he was holding the process he called a voir dire, as identified in par 6 -10 above, to determine whether he should allow cross-examination, what the Commissioner did was engage in a process to determine whether item 1, and item 2 to a lesser extent, in the HRDC letter were relevant to the issues before him in the case. There is no reference in the voir dire process to the other items in the HRDC letter in relation to which the Council was also seeking leave to cross-examine Mr Keating. The HRDC letter was in evidence as part of the issues the Council intended to raise at the hearing.
32 The process undertaken during the hearing included questioning of Mr Keating solely by the Commissioner, requiring him to meet with Mr Thompson overnight and Mr Keating giving further evidence about that meeting the following day at some length. The precise status of that conference is unclear in that Mr Thompson was not an expert witness formally briefed in the proceedings in accordance with the Court Rules. The Commissioner provided a written draft he prepared of what Mr Keating said to the parties. He asked them if that was sufficient evidence to consider Items 1 and 2 in the HRDC letter. He then ultimately refused leave for the Council to cross-examine because he considered he did not need to take into account the evidence from the voir dire process as he had sufficient material on these issues before him. The Commissioner stated that he did not intend to rely on the evidence from the voir dire process and concluded therefore that he would not allow cross-examination on Item 1 in the HRDC letter, and by inference any of the other matters raised in that letter which the Council sought to cross-examine about.
33 In these circumstances an issue of procedural unfairness does arise from the inability of the Council to participate in any part of the voir dire process undertaken by the Commissioner as it was not able to ask Mr Keating any questions during the voir dire process or in cross-examination. While the Commissioner was satisfying himself of what he considered to be the relevance of the evidence, the Council was denied any opportunity to raise questions about any of the items raised in the HRDC letter and also as to the relevance of these matters for the Commissioner's determination. This particularly applied to item 1 which occupied most time in the voir dire process and to item 2 to a lesser extent. As no reference was made in the voir dire process by the Commissioner to any of the other items in the HRDC letter for which leave to cross-examine was sought by the Council, their relevance is simply undetermined. I agree with the Council's argument that this was effectively the Commissioner clarifying, without the assistance of the parties, important traffic issues in the Council's case in the proceedings.
34 The consideration of the Commissioner's judgment to determine if the evidence from the voir dire was part of his reasoning is not an answer to this procedural unfairness. The Applicant submitted, and it appears generally the case, that all of the traffic section of the judgment referred to evidence which was before the Commissioner apart from the voir dire. One line in par 35 states that "Mr Keating had accepted the accuracy of the traffic analysis carried out by the applicant's traffic engineers Thompson Stanbury Associates". The Council argued this could only be based on the voir dire process. It does appear that this sentence in par 35 must have been informed by the voir dire because Mr Keating's evidence in it initially was that he did not take into account the data from Mr Thompson but simply referred to it in his report which was tendered in evidence. Following the overnight meeting with Mr Thompson and Mr Keating, Mr Keating expressed satisfaction with the data to the Commissioner. To the extent that there is reference in the judgment to matters arising during the voir dire process, despite the Commissioner saying he would not have regard to that, further suggests that there was procedural unfairness to the Council in the conduct of the hearing.
35 While it is within the responsibility of the Commissioner to ensure the orderly and efficient dispatch of a matter it is necessary that parties be afforded procedural fairness in doing so. The Commissioner embarked on a lengthy process of his own to determine if matters the Council sought to raise in cross-examination were relevant to the hearing. In doing so I consider he should have allowed the Council to pursue its case on the traffic issues which were clearly in issue. It was provided with no opportunity to do so in the way this part of the hearing was conducted. It was effectively excluded from the process undertaken by the Commissioner to determine the relevance of evidence on which he then based his decision whether to allow cross-examination. It is not an answer to this lack of procedural fairness to rely on his conclusion that he did not intend to rely on the evidence from the voir dire as he did not consider it relevant. The Council was not provided with an opportunity through cross-examination to test evidence in order to present its case on the issues it considered were relevant. This ground of appeal is upheld as there was a failure to accord procedural fairness in this case by not allowing cross-examination by the Council, giving rise to an error of law.
