6 The plaintiff seeks various forms of relief, essentially on the basis of alleged misleading and deceptive conduct by the defendants prior to 29 December 2004 and the breach of various contractual warranties. Mr and Mrs Hartog have cross-claimed seeking repayment of the $2.4 million held in escrow and an adjustment to the purchase price in their favour.
7 By agreement of the parties on 1 September 2006 the Court referred a number of accounting questions that are relevant to the misrepresentation and warranty case, and the cross-claim, to Mr G.C.A. Gower, for inquiry and report, including the accuracy of the Completion Accounts.
8 The referee's report was delivered on 5 April 2007 ("the First Report"). The plaintiff and the defendants identified a number of errors in the First Report and, by agreement between the parties, on 11 May 2007 the Court ordered the referee provide an explanation by way of further report in relation to a number of matters, including:
4. When calculating the material to sales ratio why did you confine yourself to particular ledger accounts and:
(a) not include all sales and sales returns in "sales";
(b) include in "materials" items which were not themselves materials;
(c) include inter-company sales within the AHE group in both "sales" and "materials";
(d) use "contra adjustments in Schedule 3.2 to the Report?
5…
6. Why did you apply the calculated materials to sales ratio to determine the inventory in the Completion Accounts when the inventory amount in the Completion Accounts did not solely include materials?
7. With respect to the "Tax Expense" figure of $273,737 in paragraph 293 of the Report: …
(c) Did you apply Accounting Standard 1020 when determining income tax expense for the 6 months ending 31 December 2004 and the carrying value for FITB? If not, why not? What is the effect on your calculations had you done so?
8.. .
9. What corrections, if any, would you like to make to the Report, in light of your answers to any of the above questions?
9 The referee provided his explanation by way of a further report dated 1 June 2007 and made a number of corrections to the First Report, which are no longer in issue. Two areas remain in dispute.
10 The first area is the referee's calculation of the material to sales ratio ("MS Ratio"), which is relevant for the purpose of the misrepresentation and breach of warranty case and his application of that ratio to determine inventory as at 30 December 2004 for the purpose of calculating the true Completion Accounts.
11 The second area is the correct application of the tax effect accounting standard to the preparation of the Completion Accounts.
The legal principles applicable to the adoption of a referee's report
12 The principles have been discussed in a number of cases. In Abigroup Contractors Pty Ltd v Sydney Catchment Authority [2005] NSWSC 662 McDougal J summarised the principles in these terms:
""11 SCR Pt 72 r 13 empowers the Court to adopt, vary or reject a report in whole or in part, and to decide any question for itself either on the evidence taken before the referee or on that and additional evidence. It reads:
"13 Proceedings on the report
(1) Where a report is made, the Court may, of its own motion, after notice to the parties, or on application by any party, on a matter of fact or law or both:
(a) adopt, vary or reject the report in whole or in part,
(b) require an explanation by way of report from the referee,
(c) on any ground, remit for further consideration by the referee the whole or any part of the matter referred for a further report,
(d) decide any matter on the evidence taken before the referee, with or without additional evidence, and shall give such judgment or make such order as the Court thinks fit.
(2) Evidence additional to the evidence taken before the referee may not be adduced before the Court except with the leave of the Court."
12 The principles by which the discretion conferred by the Rule is to be exercised are well known, and were not in dispute. I stated them, at least to my own satisfaction, in Seven Sydney v Fuji Xerox [2004] NSWSC 902. I set out what I there said at paras [11] and [12]:
"11 The principles to be applied, in exercising the discretion conferred upon the Court by Pt 72 r 13 to adopt, vary or reject in whole or in part a report of a referee, are well established. There are a number of cases to which, customarily, reference is made. They include Super Pty Ltd v SJP Formwork (Aust) Pty Ltd (1992) 29 NSWLR 549; the unreported proceedings in that case before Giles J (19 May 1992: the relevant considerations referred to by his Honour are sufficiently extracted in the decision of the Court of Appeal); Chloride Batteries Australia Ltd v Glendale Chemical Products Pty Ltd (1988) 17 NSWLR 60; White Constructions (NT) Pty Ltd v Commonwealth of Australia (1990) 7 BCL 193; and Foxman Holdings Pty Ltd v NMBE Pty Ltd (1995) 38 NSWLR 615. As to the nature and content of the referee's obligation to give reasons, the relevant authorities include Xuereb v Viola (1988) 18 NSWLR 453 and Hughes Bros Pty Ltd v Minister for Public Works (Rolfe J, 17 August 1994, unreported; BC 9402885).
12 The relevant principles, distilled from those decisions, can be stated as follows:
