JESSUP J
53 I have had the benefit of reading in draft the reasons of Branson and Stone JJ in this appeal. I agree with their Honours' conclusion and, subject to what follows, with their reasons.
54 Both the facts proved before, and the question to be determined by, the Tribunal in the present case were very simple. On the agreed facts, the applicant was contracted to Robe River Iron Associates ("Robe") to perform exploration and grade control drilling activities using its own plant and equipment. Pursuant to those contracts, Robe supplied the fuel. The question for determination by the Tribunal was whether that supply amounted to a "purchase" of the fuel by the applicant within the meaning of s 53(1) of the Energy Grants (Credits) Scheme Act 2003 (Cth) ("the Energy Grants Act"). The Tribunal identified the issues which it was required to address in terms set out in par 5 of the reasons of Branson and Stone JJ. It was not submitted on appeal that its identification of those issues involved an error of law.
55 The Tribunal's reasons were then structured according to the following headings:
6. Construction of the contracts.
7. Evidence.
8. Applicant's and respondent's contentions.
9. Purchase of fuel.
10. Consideration for fuel.
11. Proprietary interest in fuel.
12. Conclusion.
Although I have some reservation with respect to heading 6, "Construction of the contracts", I consider that the Tribunal's compartmentalisation of the matters which it had to decide was intelligible and legally sound.
56 The applicant's first ground of appeal was that the Tribunal erred by holding that whether or not there was a purchase of fuel was to be determined solely as a question of construction of the written contracts, without taking into account relevant extrinsic evidence. It is clear from a reading of the Tribunal's reasons that it did no such thing. It referred to, and considered, the applicant's evidence that it had charged Robe a contract rate which was less than it would otherwise have charged had it been required to supply its own fuel. It considered whether the facts generally would sustain the conclusion that the applicant had purchased fuel from Robe. However, as counsel for the applicant made clear in his submissions on appeal, there were no transactions pursuant to which it was alleged that the applicant had purchased fuel from Robe other than those governed by the contracts referred to in the evidence. The question whether those transactions amounted to purchases was, therefore, inevitably one which involved a consideration of the operation of those contracts.
57 The applicant's second ground of appeal was that the Tribunal erred by holding that there was no consideration for the purchase of the fuel, in circumstances where the applicant accepted a contract rate from Robe which was less than the rate which it would have accepted had it provided its own fuel. By this ground, the applicant was not suggesting that the fuel supplied by Robe was irrelevant to the consideration passing from the applicant under the contracts. Rather, it was suggesting that the Tribunal was in error in not holding that the applicant's agreement to a lesser contract rate than would otherwise have been charged should be regarded, of itself, as consideration specifically referable to the supply of fuel by Robe, sufficient to sustain the conclusion that the fuel was thereby "purchased" by the applicant. In not accepting such a suggestion, the Tribunal did not fall into legal error. It said:
There is nothing in the Contracts to support the applicant's contention that the discounted rate constituted valuable consideration for the Fuel. On a plain and literal interpretation of the words and numbers used by the parties, the relevant causes are, in the Tribunal's view, capable of meaning only that the drilling rates charged by the applicant are lower when Robe supplied diesel fuel for use in the applicant's drilling rigs, and nothing more than that.
In this passage, in my view, the Tribunal correctly characterised the nature of the contractual exchange as between the applicant and Robe.
58 The applicant's third ground of appeal was that the Tribunal erred by holding that the applicant did not purchase fuel from Robe, and by holding that it acquired a mere licence from Robe to consume the fuel. This ground involves the nub of the applicant's case on appeal, and refers to what was, in my view, central to the Tribunal's decision, namely, whether property in the fuel passed to the applicant upon physical delivery into the fuel tanks of the applicant's plant and equipment. The essence of the applicant's case in relevant respects appears to have been that, since the fuel was physically delivered into its tanks, since the fuel was used, since nearly all the fuel was consumed and thus could never be returned to Robe, and since the very small amount of fuel remaining at the end of a job could be used by the applicant without having to account to Robe therefor, there must have been a passing of property. The Tribunal did not accept that proposition. It referred to a number of contractual and other considerations which made it unlikely. In so proceeding, the Tribunal did not, in my view, make any error of law. Further, it found that there was no bilateral intention, as between the applicant and Robe, for property in the fuel to pass. That was a finding of fact. In making it, the Tribunal took a conventional and unexceptionable approach to the ascertainment of the parties' intentions by reference to objective, mutually known, circumstances. The Tribunal's reasoning in relevant respects did not involve any error of law.
59 The applicant's fourth ground of appeal was that the Tribunal had erred in failing to consider relevant and admissible material in construing the contracts in question, on the basis that judgments of the High Court subsequent to Codelfa Constructions Pty Ltd v State Rail Authority of New South Wales (1982) 149 CLR 337 were considered to be inconsistent with Codelfa itself. It is in relation to this ground that I would express a reservation as to the approach taken by the Tribunal under heading 6 of its reasons. It seems that the Tribunal referred to the Codelfa line of jurisprudence because of a submission on behalf of the applicant that it should have been held that a calculable discount on the contract rate allowed by the applicant to Robe when Robe supplied fuel under the contracts should have been recognised as payment for the fuel by the applicant. What the applicant appears to have put to the Tribunal was that, whatever the contracts themselves may have disclosed, the reality of the transactions between the applicant and Robe was that the applicant specifically reduced - or "discounted", as it was put - the contract price which it would otherwise have accepted from Robe in consideration of Robe supplying fuel. A consideration of that submission did indeed require the Tribunal to look beyond the terms of the contracts (something which it did not decline to do). However, whether or not the submission had any merit, it did not raise a question of the construction of the contracts between the applicant and Robe. Rather, the applicant's submission raised a question of characterisation. I shall attempt to explain what I mean by that distinction.
60 No question arose as to the content of the parties' obligations under the contracts which were before the Tribunal. Whether or not the Tribunal had been prepared to look at so-called extrinsic evidence, the result could not have been the attribution to the contracts of meanings which differed from their written terms, such that the parties' obligations would be affected in some relevant respect. Whatever the Tribunal did in relation to extrinsic evidence, Robe was required to supply fuel under the contracts, the applicant was required to carry out work, and Robe was required to pay the contract price. The real question was whether the transactions for which the contracts provided included one which answered the description of a "purchase" within the terms of s 53(1) of the Energy Grants Act. This question was, as I have said, one which required the identification of the legal character of the transactions in question. It was not, in my view, a question of construction at all. In the circumstances, the present is not, in my respectful view, an appropriate occasion for the court to consider Codelfa and subsequent High Court authority in the same line.
61 Returning to the Tribunal's reasons, although it did refer to the principles for which Codelfa stands, nothing much seemed to turn on that circumstance. As I have indicated above, the Tribunal did take into account facts and circumstances standing outside the written words of the contracts before it for the purposes of deciding whether the applicant had purchased fuel from Robe. I agree with Branson and Stone JJ that the mere fact that the Tribunal did not refer to cases subsequent to Codelfa does not mean that it necessarily made an error of law. However, I would prefer to base my conclusion in relevant respects upon the circumstance, which I consider to be clear, that the Tribunal did approach the issues presented by the contracts between the applicant and Robe as involving the characterisation of the transactions for which those contracts provided. That approach was, in my view, free of any error of law.
62 I agree that the appeal should be dismissed with costs.
