18 Counsel for the appellants submitted that the right to cross-examine is not an arcane legal principle, and referred to a number of authorities in which cross-examination in administrative tribunals has been dealt with. Counsel referred to observations of Evatt J. in R v. War Pensions Entitlement Appeal Tribunal; Ex parte Bott (1933) 50 CLR 228 at 256, 257. Evatt J. stated, in a clear way, his view on the observance of the rules of evidence as a method of inquiry best calculated to prevent error and elicit truth. On the facts of Bott's case the Appeal Tribunal departed in several ways from the manner in which proceedings are conducted at common law, and not allowing cross-examination was one of them. In the majority view the Tribunal had not departed from the real performance of its duty and its decision was not subject to mandamus. Starke J, who was in the majority, said to the effect that the Appeal Tribunal did not violate any substantial requirement of justice (249), "… Whether the cross-examination shall take place upon that opinion is entirely a question for the discretion of the Tribunal …" (250) and "The Repatriation Commission and the Appeal Tribunal gave him a full and fair opportunity of presenting his case, in a full and fair hearing." (247-248). In my opinion Bott's case shows that there may well be circumstances in which a fair hearing takes place although cross-examination is not allowed.
19 Counsel also referred to observations of Hunt J. in Allied Pastoral Holdings Pty Ltd v. Federal Commissioner of Taxation [1983] 1 NSWLR 1 at 17 and 22, to A & B v. Director of Family Services [1996] ACTSC 48 [paras 26-37] Higgins J. and to Stead v. State Government Insurance Commission (1986) 161 CLR 141.
20 In trial practice under the common law cross-examination has high importance, expectations about the presentation of factual issues for decision and about the conduct of advocates are closely related to the manner in which cross-examination is conducted and, while a court has discretionary power to control or limit cross-examination, those controls are used in a restrained manner. The practices of common law courts are not the only way in which fair procedures may lead to a just determination of facts which are in dispute. As ever when a claim is made that Natural Justice has not been accorded, regard must be paid to the legal context in which the decision-maker operates and to the law regulating the conduct of the proceedings.
21 Proceedings before the Commission are dealt with in Chapter 7 of the WIMWCA and s.354 is as follows:
354 Procedure before Commission
(1) Proceedings in any matter before the Commission are to be conducted with as little formality and technicality as the proper consideration of the matter permits.
(2) The Commission is not bound by the rules of evidence but may inform itself on any matter in such manner as the commission thinks appropriate and as the proper consideration of the matter before the Commission permits.
(3) The Commission is to act according to equity, good conscience and the substantial merits of the case without regard to technicalities or legal forms.
(4) Proceedings need not be conducted by formal hearing and may be conducted by way of a conference between the parties, including a conference at which the parties (or some of them) participate by telephone, closed-circuit television or other means.
(5) Subject to any general directions of the President, the Commission may hold a conference with all relevant parties in attendance and with relevant experts in attendance, or a separate conference in private with any of them.
(6) If the Commission is satisfied that sufficient information has been supplied to it in connection with proceedings, the Commission may exercise functions under this Act without holding any conference or formal hearing.
(7) An assessment or determination is to be made by the Commission having regard to such information as is conveniently available to the Commission, even if one or more of the parties to the assessment or determination proceedings does not co-operate or ceases to co-operate.
(8) In proceedings before a court with respect to a claim for work injury damages (other than proceedings under section 235A or 235C or under the Crimes Act 1900 with respect to fraud), evidence of a statement made in proceedings before the Commission is not admissible unless the person who made the statement agrees to the evidence being admitted.
22 Section 354(3) has a general but not exact resemblance to s.36(3) of the Workers Compensation Act 1926, which referred to the real merits and justice of the case. Section 36(3) appears to have had little influence on the procedure followed by the courts which heard proceedings under that Act; see Deigman v. State Coal Mines [1956] 30 WCR (NSW) 169 (Judge Rainbow) at 177 and 178. Section 354 and other provisions give the present Commission a wider range of discretionary choices about the procedure appropriate for a particular case than existed under earlier legislation.
23 The Arbitrator is to attempt conciliation (s.355). The Commission may require attendance at a conference in connection with proceedings (s.359); this furnishes an occasion for carrying out the duty in s.355 to attempt conciliation. The Commission may control representation of a party by a legal practitioner or an agent in some circumstances (s.356). The Commission may require persons including parties to furnish information (s.357) and may provide documents and information to parties (s.358).
24 In the Workers Compensation Commission Rules 2003 made under the WIMWCA the principal means of approaching the Commission is an application to resolve the dispute (Rule 37). The parties are required, within limited times, to lodge and serve all the information and documents on which they propose to rely and to make statements revealing the specific nature of their evidence and other material related to producing it (Rules 38 and 42).
25 The requirements of the rules for information to be lodged in advance and for statements revealing the cases of parties to be made in advance, taken with the width of the sources of information on which the Commission is authorised to act and the ways in which it is authorised to proceed, mean that assumptions upon which common law trials are conducted should not be readily carried over when testing contentions that a hearing before an Arbitrator was not conducted in a fair way. The overall and continuing duty under s.355 to use best endeavours to bring the parties to settlement acceptable to all of them must have large influence on the manner in which proceedings are conducted. The environment of contestation and the confrontational methods of the common-law trial would not usually be appropriate; there may be issues of kinds which it is appropriate to deal with in that style, and much is left to the discretion of the Arbitrator. The Arbitrator is in a good position to decide on and to impose appropriate controls on the adduction of evidence, by cross-examination or otherwise. The Arbitrator will usually be in a position to perceive whether a wish to pursue an issue has a basis, whether it is a sound basis, whether some issue or line of questions is merely exploratory, or for that matter whether questions are merely the product of inventiveness.
26 In the present case the Arbitrator was in possession of the material lodged in advance of the hearing by the parties, and was entitled to act on the material. This put her in a good position to make a judgment about whether treatment or further treatment of any issue or line of inquiry in cross-examination was appropriately to be allowed or to be restricted.
27 The principal burden of the matter complained of, and the principal subject of the ruling limiting cross-examination was exploration of the time of the confrontation in which the worker was injured. On any view, this cannot have been an important matter and I find it understandable that the Arbitrator regarded it as appropriate to limit questioning and the adduction of evidence. All the information lodged by the parties suggested that the event happened before the ordinary starting time, Mr Zheng's statement was to the effect that he had arrived at work, started the compressor and was entering the factory where a number of other employees already were, and Mr Bui's statement was to the effect that he approached Mr Zheng on a subject relating to the employer's interests and property and chose to approach Mr Zheng because he had some apparent authority. Except in the respect that it could be contended that Mr Zheng took himself out of a course of his employment by spitting on Mr Bui there really was nothing of sufficient apparent substance to justify disputing that the injury arose out of or in the course of employment. In particular the time of the event was not of any importance, and nothing of any real value can have been lost by restricting the opportunity to cross-examine on that subject. The information narrated by the appellant's solicitor was to the effect that the restriction was imposed after he had cross-examined Mr Zheng for about 35 minutes. It must be said that in my view sufficient time was made available for the cross-examiner to reach the subject matters which were important, and that if the opportunity to deal with alleged shortcomings in Mr Zheng's own conduct, in so far as it was based on the information apparently available, had not been dealt with in that time, and the wish was expressed to continue cross-examination to explore something which does not appear to have had much substance, the intervention which the Arbitrator made was an altogether unremarkable exercise of the discretionary power to control proceedings.
28 There are aspects of the facts as stated by Mr Bui which his statement did not make clear. Where the statement says that Mr Zheng did not reply to Mr Bui's inquiry, simply looked at him and after a few seconds spat on his face, the word "spat" is in inverted commas, and this gives rise to some doubt as to what Mr Bui said had happened; whether the appearance was that Mr Zheng deliberately spat in Mr Bui's face by way of response to his inquiry, or whether the event did not appear to be deliberate. Without some further explanation from Mr Bui it is not really possible to know what he was asserting had happened. The inverted commas may indicate that the event was not quite what would ordinarily be understood by the word "spat", they may be there for emphasis or there may be some other explanation. The Arbitrator said, reasonably enough, "… the use of inverted commas seems to imply that it is not meant literally." (Red 47 [43]). When Mr Bui said "… I instinctively raised my hand and struck Zheng with the piece of aluminium grate in the head …" there is room for further explanation about what was referred to as "instinctively" and whether Mr Bui states that he deliberately struck Mr Zheng, or whether the first striking of Mr Zheng with a piece of aluminium crate in the head was an accidental result of instinctively raising his hand. Mr Bui's statement makes it clear that at the next stage when Mr Zheng swung his bag at Mr Bui, Mr Bui struck him again to defend himself; plainly this was deliberate, but the language which makes this clear casts doubt on whether Mr Bui intended to strike Mr Zheng on the first occasion.
29 Another small mystery is that in the course of the statement apparently taken from Mr Zheng by an investigator, it was put to Mr Zheng that he had made a rude sign to Mr Bui, but Mr Bui does not say in his statement that any such thing happened; nor does Mr Pham.
30 If the employer claimed to be entitled to succeed on the ground that Mr Zheng had departed from the course of his employment, or had been guilty of serious and wilful misconduct, there was a need for the employer to do more than put Mr Bui's statement before the Arbitrator and attempt to elicit facts adverse to Mr Zheng's case by cross-examination of Mr Zheng; notwithstanding that Mr Zheng bore the onus of proof, there was a forensic need for the employer to make clear what it was that Mr Bui said had happened, more clearly than his statement showed, and this could be done by bringing Mr Bui to give oral evidence, or by producing a further and clearer statement, neither of which was done. Considerations of these kinds were available for the Arbitrator to consider, whether expressly or not, when assessing whether further cross-examination was required in fairness.
31 The ordinary expectation should reasonably be that every material thing which a witness has to say about the facts will appear in the statement of the witness produced before the Arbitration hearing by the person who relies on what a witness has to say. The Arbitrator no doubt can allow departures from this ordinary expectation, but the employer did not bring Mr Bui to the hearing, or seek any opportunity to obtain any further or clearer statement from him. In this forensic context I see no reason to doubt that the Arbitrator would have been in a position, after about half an hour or three-quarters of an hour had been spent on cross-examining Mr Zheng on a fairly limited set of facts, to decide whether it was appropriate to allow cross-examination to continue.
32 As decisions of an arbitrator are subject to appeal to a Presidential member under s.353 an arbitrator is under a duty to make a record of the evidence during the Arbitration hearing. The Commission has published a Record of Proceedings Policy. That Policy requires proceedings to be recorded during the Arbitration hearing phase where the parties are not settling their dispute and the Arbitrator must determine it. The Policy provides for recording proceedings by digital sound recording, producing a compact disc, a copy of which is to be provided to a party on request at no cost. The Commission does not provide a written transcript of Arbitration hearings. The Policy makes different provision for hearings before Presidential members, for which there is to be a written transcript. In the present case, for reasons which were not explained, there was no compact disc or sound recording of the Arbitration hearing and the evidence given there. This is a serious shortcoming, because it greatly impedes the right of appeal and the due exercise of powers of the Presidential member under s.352; and also impedes the conduct of a further appeal under s.353. According to circumstances, the absence of a sound recording could fairly readily lead a Presidential member to a decision to require a rehearing; although that result would not be automatic.
33 In the present case this large shortcoming was overcome by the Deputy President's acceptance of the following narration made by the solicitor who appeared at the Arbitration hearing for the employer of the events of which he complained in a letter dated 14 November 2003 to the Workers Compensation Commission:
5. The appellant submits that the Arbitrator was in error in purporting to rely on what is described as "sworn evidence of Mr Zheng" having regard to the fact of the employer having been denied natural and substantial justice in the course of the arbitration, in particular in respect of the evidence of Mr Zheng. In this regard the employer was specifically and expressidly prevented, by the Arbitrator, from testing the evidence of Mr Zheng by asking relevant and important questions on a number of critical issues including in particular (but not necessarily limited to) the issue of the fact of the altercation occurring prior to the applicant commencing work. Were a transcript available it would confirm several instances of the Arbitrator preventing the representative of the employer from questioning the applicant. Indeed at one point of the arbitration an exchange to the following effect took place between the Arbitrator and the representative of the employer:-
Arbitrator "I am not going to let you ask questions about that, we all know what the issues are in this case".
