CONSIDERATION OF 3D SCAFFOLDING'S APPEAL
21 It is clear from a reading of the transcript of the cross-examination of Mrs Montgomery that, at the Tribunal hearing, the Commissioner directly challenged the reliability and authenticity of the Price Spreadsheets that she had prepared. At the time of her cross-examination, if not earlier, Mrs Montgomery and 3D Scaffolding must, therefore, have been aware that the Commissioner was alleging that she had fabricated the Price Spreadsheets. Mrs Montgomery's cross-examination specifically established that she had created a Price Spreadsheet in respect of items that had not been for hire but for sale. Moreover, the Commissioner specifically put to her that the relevant documents had been fabricated so as to arrive at numbers corresponding to the cashed cheques: see AAT transcript, pp 274-275.
22 We agree with the primary judge that both Mrs Montgomery and 3D Scaffolding were on notice from the questions put to Mrs Montgomery in cross-examination that the Price Spreadsheets were challenged as having been fabricated and that there were ample opportunities at the hearing to respond to this allegation. If Mrs Montgomery had an answer to the allegation, counsel for 3D Scaffolding might have elicited the answer in re-examination. Alternatively, it would have been open to 3D Scaffolding to seek the Tribunal's leave to adduce additional evidence in chief: see s 33(1)(c) of the Administrative Appeals Tribunal Act, discussed in Re Kowalski and Military Rehabilitation and Compensation Commission (2007) 47 AAR 300; [2007] AATA 1988 at [35]-[40]; Re Groom and Secretary, Department of Families, Housing, Community Services and Indigenous Affairs [2008] AATA 202; and Sullivan v Department of Transport (1978) 1 ALD 383, at 403-404 per Deane J.
23 Further, the Commissioner's submissions of 1 June 2007 made a clear, direct and detailed attack on the reliability and genuineness of the Price Spreadsheets. It would have been open to 3D Scaffolding to respond to the allegation of fabrication in its reply submissions. The document prepared for us, headed "Price Spreadsheets - Annexure A", shows that some response of this kind might have been given at that earlier time. 3D Scaffolding made no such response, however, but merely made the complaint rejected by the Tribunal and advanced here - that there had been a denial of procedural fairness. The allegation of fabrication was clearly and directly made, however, and there was plainly an opportunity to respond to the allegation. Accordingly, there was no denial of procedural fairness.
24 3D Scaffolding relied on Commissioner of Taxation v Metaskills Pty Ltd (2003) 130 FCR 248 in support of its denial of procedural fairness argument. This case is clearly distinguishable. In Metaskills, an issue as to "Whose income?" was raised only on the eve of the Tribunal hearing. Lindgren J concluded that, "[i]n the circumstances, it is to set the standard too high to require that, at its peril, Metaskills must, through Mr Strong [a non-lawyer], appreciate the significance of what was happening and take the initiative of seeking an adjournment": see Metaskills 130 FCR at 273 [144]. His Honour considered that, if there had been an adjournment, then Metaskills might have been able to lead additional relevant evidence.
25 In the present case, it was clear at the commencement of the Tribunal hearing that the Commissioner had successfully challenged the existence of Modular Scaffold and was continuing to challenge the existence of Mr Borg. It followed that, as the Commissioner submitted on the appeal, any documentation that 3D Scaffolding put forward in support of an account involving Mr Borg was also under challenge. It is to be borne in mind that 3D Scaffolding was represented by experienced counsel. Further, it is abundantly clear that, after the oral hearing had concluded (and before the Commissioner made the submissions the subject of complaint), 3D Scaffolding appreciated that the Commissioner was alleging that Mrs Montgomery had fabricated the Price Spreadsheets. This is evident from [14] and [15] of the Submissions of the Applicant dated at 1 June 2007: compare the Commissioner's Submissions also dated 1 June 2007, part of which became the Annexure A. These circumstances make the present case entirely different from Metaskills.
26 3D Scaffolding also relied on the decision in Hoskins, in which the Court found that "topics which were the subject of important findings against the applicant were not directly put to him", noting that "[t]he essence of the unfairness, if there was any, was that it was never suggested to the applicant that he was exaggerating his condition, as the Tribunal found": see Hoskins 32 FCR at 446 per Pincus J. The Court held that the applicant was entitled to have the decision set aside "unless the question of exaggeration should be taken to have been inherently in issue": Hoskins 32 FCR at 446. In the circumstances of that case, the Court found that "a claimant must, especially when represented professionally, surely appreciate that his or her task is to convince the Tribunal of the reality and seriousness of the complaints made" and, accordingly, the failure to cross-examine the applicant in the way alleged did not amount to a breach of procedural fairness: see Hoskins 32 FCR at 447.
27 We can accept the analysis made by Pincus J in Hoskins. The result in this case must be the same as in Hoskins, because, as in Hoskins, having regard to the matters already outlined, 3D Scaffolding and Mrs Montgomery were on notice and must be taken to have appreciated that the authenticity and reliability of the Price Spreadsheets were in issue.
28 3D Scaffolding also sought to propound submissions in reliance on the rule in Browne v Dunn. The primary judge held that the rule in Browne v Dunn applied in a proceeding before the AAT. Neither party contested this ruling before us.
29 What is commonly called the rule in Browne v Dunn refers to the rule of practice established in the decision of the House of Lords in Browne v Dunn (1893) 6 R 67. The rule is an aspect of procedural fairness. In Allied Pastoral Holdings Pty Ltd v Commissioner of Taxation [1983] 1 NSWLR 1 at 16, Hunt J conveniently re-stated the rule:
… unless notice has already clearly been given of the cross-examiner's intention to rely upon such matters, it is necessary to put to an opponent's witness in cross-examination the nature of the case upon which it is proposed to rely in contradiction of his evidence, particularly where that case relies upon inferences to be drawn from other evidence in the proceedings.
30 We accept that, as Hill J said in Jagelman v Federal Commissioner of Taxation (1995) 31 ATR 463 at 473:
Where the issues in a case are such that it would readily be apparent to a party that a particular imputation has been made, there will be no necessity to put that imputation to a witness who denies it and, in consequence, there will have been no denial of procedural fairness …
31 Also pertinent to the present case are certain observations of Hunt J in Allied Pastoral. His Honour said (at [1983] 1 NSWLR at 22-23) that:
A challenge made to the evidence of a witness in the course of a final address may take place in various ways. The opposing party may ask the tribunal of fact simply to disbelieve that evidence; if he has led evidence in direct contradiction of the evidence of that witness, he may then ask the tribunal of fact to accept the evidence of his own witnesses in preference to that of the witness in question; or he may point to other evidence in the case, led by either party, which tends either to contradict the evidence of that witness or to destroy his credit. There are many reasons why it should be made clear, prior to final addresses and by way of cross-examination or otherwise, not only that the evidence of the witness is to be challenged but also how it is to be challenged. Firstly, it gives the witness the opportunity to deny the challenge on oath, to show his mettle under attack (so to speak), although this may often be of little value. Secondly, and far more significantly, it gives the party calling the witness the opportunity to call corroborative evidence which in the absence of such a challenge is unlikely to have been called. Thirdly, it gives the witness the opportunity both to explain or to qualify his own evidence in the light of the contradiction of which warning has been given and also, if he can, to explain or to qualify the other evidence upon which the challenge is to be based. …
In many cases, of course, counsel for the party calling the witness in question will be alert to the relevance of the other material in the case to be relied upon for the challenge to the truth of the evidence given by his witness or to the credit of that witness, and in those circumstances counsel will be able to give his witness the opportunity to deal with that other material in his own evidence in chief.
32 In the present case, in the course of the Tribunal hearing and in cross-examining Mrs Montgomery, the Commissioner very clearly challenged the genuineness and reliability of the Price Spreadsheets and related documentation. The imputation as to the fabrication of the Price Spreadsheets was directly put to Mrs Montgomery, who denied the allegation. Having regard to the authorities, there was no breach of the rule in Browne v Dunn and no denial of procedural fairness on such a basis.
33 Having regard to the evidence and the submissions before it, it was plainly open to the Tribunal to take the view that Mrs Montgomery had manipulated the figures on the Price Spreadsheets in order to make them correspond with the amount on the cheques as cashed. It must be borne in mind that, in its written submissions dated 1 June 2007, 3D Scaffolding invited the Tribunal to treat the Price Spreadsheets as reliable and genuinely derived from other business records. 3D Scaffolding argued in these submissions that fabrication was not a tenable imputation, having regard to the entirety of the documents. In this circumstance, there was nothing remarkable about the Commissioner's contrary submission to the effect that fabrication was evident from the face of the documents and, in particular, that the figures on the Price Spreadsheets had been manipulated by either omitting or falsely inserting information in order to reach figures corresponding with the cheques that had been drawn.
34 In any event, the Tribunal's decision did not turn on the Price Spreadsheets. Ultimately, as we have seen, the Tribunal discussed them very briefly (whilst adopting the Commissioner's analysis set out in Annexure A as its own). This is because, once the Tribunal found that not only Modular Scaffold but also Mr Borg did not exist, then 3D Scaffolding had to fail because it could not discharge the onus that lay on it. Further, once the Tribunal found that Mr Borg did not exist and that Mr Borg was James Docherty, the alleged arrangements for paying Mr Borg were very largely irrelevant. The Price Spreadsheets and collateral documentation that 3D Scaffolding relied on to demonstrate Mr Borg's existence and the arrangements made to pay him also ceased to have any significance.
35 It follows from this that, even if the alleged breach of procedural fairness were established, the error could not have affected the result. It is well accepted that an immaterial error of law will not vitiate a Tribunal's decision: see BTR PLC v Westinghouse Brake and Signal Co (Australia) Ltd (1992) 34 FCR 246 at 253-254 per Lockhart and Hill JJ and Klinkert v Australian Postal Corporation (1992) 16 AAR 86 at 92 per Hill J. It is apparent that the Tribunal would have reached the same result, whether or not an error of the kind alleged were made by it: compare Stead v State Government Insurance Commission (1986) 161 CLR 141 at 145 per Mason, Wilson, Brennan, Deane and Dawson JJ.
36 For these reasons, we would dismiss the appeal brought by 3D Scaffolding, with costs.
