The contractual claim
46The principles relating to the construction of a commercial contract are not in doubt. They were recently summarised by the High Court in Electricity Generation Corporation v Woodside Energy Ltd [2014] HCA 7; (2014) 306 ALR 25 at [35] in these terms:
[T]his Court has reaffirmed the objective approach to be adopted in determining the rights and liabilities of parties to a contract. The meaning of the terms of a commercial contract is to be determined by what a reasonable businessperson would have understood those terms to mean. That approach is not unfamiliar. As reaffirmed, it will require consideration of the language used by the parties, the surrounding circumstances known to them and the commercial purpose or objects to be secured by the contract. Appreciation of the commercial purpose or objects is facilitated by an understanding "of the genesis of the transaction, the background, the context [and] the market in which the parties are operating". As Arden LJ observed in Re Golden Key Ltd, unless a contrary intention is indicated, a court is entitled to approach the task of giving a commercial contract a businesslike interpretation on the assumption "that the parties ... intended to produce a commercial result". A commercial contract is to be construed so as to avoid it "making commercial nonsense or working commercial inconvenience". [footnotes omitted]
47The court may not have regard to the negotiations between the parties for the purpose of determining the correct construction of the contract except to the extent that those negotiations establish objective facts, which were known to both parties and which, therefore, form part of the context in which the contract is to be interpreted. As Mason J said in Codelfa Construction Pty Ltd v State Rail Authority of New South Wales [1982] HCA 24; (1982) 149 CLR 337 at 352:
... prior negotiations will tend to establish objective background facts which were known to both parties and the subject matter of the contract. To the extent to which they have this tendency they are admissible. But in so far as they consist of statements and actions of the parties which are reflective of their actual intentions and expectations they are not receivable. The point is that such statements and actions reveal the terms of the contract which the parties intended or hoped to make. They are superseded by, and merged in, the contract itself. The object of the parol evidence rule is to exclude them, the prior oral agreement of the parties being inadmissible in aid of construction, though admissible in an action for rectification.
Mason J referred to one possible exception to this general principle (at 352-3):
There may perhaps be one situation in which evidence of the actual intention of the parties should be allowed to prevail over their presumed intention. If it transpires that the parties have refused to include in the contract a provision which would give effect to the presumed intention of persons in their position it may be proper to receive evidence of that refusal. After all, the court is interpreting the contract which the parties have made and in that exercise the court takes into account what reasonable men in that situation would have intended to convey by the words chosen. But is it right to carry that exercise to the point of placing on the words of the contract a meaning which the parties have united in rejecting? It is possible that evidence of mutual intention, if amounting to concurrence, is receivable so as to negative an inference sought to be drawn from surrounding circumstances.
48Generally, the court may not have regard to the subsequent conduct of the parties in interpreting the contract: Agricultural & Rural Finance Pty Ltd v Gardiner [2008] HCA 57; (2008) 238 CLR 570; Franklins Pty Ltd v Metcash Trading Ltd [2009] NSWCA 407; (2009) 76 NSWLR 603. However, evidence of post-contractual conduct may be admissible as an admission to prove a fact which is relevant to the parties' contractual obligations: see Johnston v Brightstars Holding Company Pty Ltd [2014] NSWCA 150 at [79]-[84] per Beazley P; at [121] per Basten JA; at [134] per Gleeson JA. The relevant fact may be what was said where the contract is an oral one. It may also be a fact that forms part of the context in which the agreement was reached, a fact concerning whether agreement was reached or a fact concerning whether the agreement was wholly in writing or is to be found in the conversations between the parties as well. However, as Basten JA pointed out in Johnston v Brightstars Holding Company Pty Ltd at [121]:
... to the extent that the evidence reveals an opinion as to a question of law rather than fact, the admission may be irrelevant or valueless.
49As I have said, the plaintiffs' primary claim is that, on the correct construction of the JVA, it requires the Joint Venture Parties, by a date which is 30 Business Days after Planning Approval is obtained, to borrow sufficient funds to pay out the NAB loan and to complete the project. That is said to be the effect of cl 11 of the JVA when understood in the context in which the joint venture was established and in the context of other terms of the JVA and the Facility Agreement. The plaintiffs also submit that regard can be had to the negotiations for the JVA, and, in particular, their rejection of Option 1 of the term sheet circulated by Mr Taber on 1 December 2009. In addition, they rely on Mr Taber's email dated 29 April 2010 and the fact that Villawood Management Pty Ltd prepared a finance application in December 2013 that contemplated the joint venture would borrow sufficient funds to pay out the NAB loan as admissions that can be taken into account in construing the agreement.
50It is helpful to consider first the surrounding circumstances and the question of what other material can be taken into account in interpreting the terms of the JVA.
51The most significant surrounding circumstances relied on by the plaintiffs are their financial position and the fact that they could not repay the NAB debt themselves. In my opinion, stating the position in those terms puts the point too highly. I accept that, without a joint venture, the plaintiffs were not in a position to repay the NAB debt without selling the land; and Schofields must have known that to be the case. Apart from anything else, that knowledge can be inferred from the structure of the payments to be made by Schofields in order to obtain a 50 percent interest in the joint venture. The terms of the Facility Agreement required Schofields to make an initial payment of $3 million together with any shortfall in the refinancing of the NAB loan, plus eight payments of $250,000 each quarter, interest payments from 1 April 2010 and a capital payment if NAB required the debt to be reduced. Apart from some interest payments, those payments permitted Schofields to obtain an interest in the joint venture and land on the basis that the land was worth $30 million. It seems clear that the parties expected the value of the land to increase. Consequently, it was to the plaintiffs' advantage to make interest and principal payments if they could since the result would be that Schofields would have to pay more to acquire 50 percent of the land and a 50 percent interest in the joint venture. It must have been evident from the fact that the plaintiffs negotiated for terms of the JVA and Facility Agreement that provided for Schofields to make those payments that the plaintiffs could not make those payments themselves. It is difficult to understand why the payments to be made by Schofields were structured in the way that they were if the position were otherwise.
52However, I do not think that it follows that the parties knew that the plaintiffs would not be able to repay the loan once Planning Approval was obtained. The plaintiffs could not repay that loan out of their own resources. However, following Planning Approval, they were entitled to a further payment from Schofields. The plaintiffs submit that little weight can be placed on that consideration because the further payment depended on obtaining a valuation and the process under the JVA for obtaining that was likely to take longer than the 30 Business Days in which the plaintiffs must repay the debt; and, in any event, it must have been obvious to the parties that the amount to be paid would not be sufficient to cover the amount of the loan. However, there is nothing in the JVA that prevents the plaintiffs from borrowing the amount to repay the loan to NAB. Clause 23.1 states that a Joint Venture Party must not "Alienate" or in any other way deal with its interest before Planning Approval is obtained other than with the consent of the other Joint Venture Party. It says nothing about the position after Planning Approval is obtained. The definition of "Alienate" excludes an alienation "by way of security". Moreover, the prohibition in cl 23.1 does not apply where the alienation is made to comply with obligations under the JVA. The plaintiffs were not in a position to borrow the amount of the existing NAB loan before Planning Approval. However, at the time the JVA was entered into, the parties expected the value of the land to increase substantially following the granting of Planning Approval, the parties knew that it was likely that Dairycorp would be entitled to a further payment under the JVA, that Dairycorp would be in a joint venture with a successful property developer and that it would be expected to have a 50 percent interest in that joint venture and the profits it generates. Finally, the parties must have understood that much of the development risk would be removed by the granting of Planning Approval. Consequently, they may well have anticipated that, following Planning Approval, Dairycorp would be in a position itself to raise funds to pay out the NAB loan. Certainly, I do not think it could be said that Schofields knew that that was not the case.
53The plaintiffs seek to rely on evidence of the pre-contractual negotiations and, in particular, on their rejection of Option 1 of the amended term sheet circulated by Mr Taber on 1 December 2009, the draft JVA circulated by Mr Mazzone on 23 December 2009, Mr Downing's comment on cl 9 of that draft on 11 January 2010 and Mr Mazzone's response on 15 January 2010 as shedding light on the meaning of the JVA and cl 11, in particular. However, they seek to do so for an impermissible purpose. The plaintiffs rely on those documents to establish that the intention of the parties was that, following the granting of Planning Approval, the joint venture would become responsible for the NAB debt. That is directly contrary to the principle stated by Mason J in Codelfa. I accept Schofields' submission that this is not a case where the parties have refused to include in the contract a provision which would give effect to what Schofields says was their presumed intention so as to fall within the possible exception identified by Mason J. It cannot be said that the parties refused to include a term in the JVA stating that Dairycorp would be responsible for repaying the NAB debt. Indeed, cl 11(a)(ii) (about which I say more below) seems to be just such a clause. The fact that an earlier term sheet proceeds on the basis that Dairycorp would not be responsible for repaying the NAB debt is not itself such a refusal.
54The plaintiffs seek to rely on Mr Taber's email dated 29 April 2010 and the finance application prepared in December 2013 as evidence of post-contractual admissions. But the plaintiffs do not identify the relevant admission. It is apparent that they seek to rely on those documents as demonstrating that it was Schofields' intention that the joint venture would become responsible for the NAB debt following the granting of Planning Approval. Once again, it seems to me that that is an impermissible purpose.
55It follows that the intention of the parties must be ascertained largely from the words used in the JVA and Facility Agreement but understood in a context where Schofields was required to make certain payments to acquire a 50 percent interest in the land and the joint venture, and where Dairycorp was unable to service its existing debt but there was no reason to think that it would not be capable of repaying that debt once Planning Approval had been granted.
56As I have said, cl 11(a)(ii) appears to contain a clear statement that, by a date which is 30 Business Days after Planning Approval is obtained, Dairycorp agrees to pay its existing debt facility and to procure a release of all securities, so that the land can be made available as security for the project debt which the JVA contemplates will be raised by the joint venture. Significantly, cl 11(a)(ii) says that "Dairycorp" agrees to pay its existing debt facility. It does not say that the joint venture agrees to do so.
57The plaintiffs submit that cls 11(a)(i) and 11(a)(ii) need to be read together, that their order is important and that that order, and the use of the word "and" at the end of cl 11(a)(i), suggest that the joint venture will obtain external financing and that Dairycorp will then use part of that external financing to repay its existing debt to NAB. However, that interpretation is not obvious on the drafting of cl 11(a). The clause says that two things are to happen within 30 Business Days of Planning Approval. One is the raising of new debt. The other is the repayment by Dairycorp of the existing debt so that the security held by NAB over the land can be released. That explains the use of the word "and". There is nothing in cl 11(a) to suggest that Dairycorp's repayment obligation is dependent on the joint venture obtaining external financing for the joint venture. The fact that the two events are to occur by the same date suggests the opposite. It is to be expected that, if the parties had intended that the joint venture would be responsible for repaying the NAB debt, cl 11(a)(ii) would have said so, instead of saying that it was the responsibility of Dairycorp.
58The plaintiffs rely on other terms of the JVA and Facility Agreement which they say support the interpretation of cl 11 for which they contend. The most significant clause is cl 4.4 of the Facility Agreement. That clause sets out the payment to be made by Schofields to equalise the parties' interests in the joint venture. The plaintiffs submit that it makes no sense to deduct from that payment the amount of the NAB debt if the parties intended that Dairycorp would be responsible for repaying that debt.
59The plaintiffs' submission based on cl 4.4 of the Facility Agreement would have considerable force if cl 4.4 required the whole of the NAB debt to be deducted from the amount payable by Schofields to obtain a 50 percent interest in the joint venture. The other advances to be made by Schofields under the Facility Agreement suggest that it was to earn a 50 percent interest in the joint venture (and the land) by paying 50 percent of the value of the land. If the amount of the NAB debt is deducted from the final payment, that strongly suggests that the parties intended that Schofields would assume the responsibility for half of that debt through the joint venture, otherwise it would be paying substantially less than 50 percent of the value of the land to acquire a 50 percent interest in the joint venture.
60The difficulty, however, is that the formula stated in cl 4.4 does not require the whole of the NAB debt to be deducted from the payment to be made by Schofields. Rather, it requires that, at most, a proportion of that debt be deducted. The proportion to be deducted depends on the participating interest that Schofields has already obtained through earlier payments. The greater the participating interest that Schofields earns through advances made before Planning Approval is obtained, the smaller the proportion of the existing debt that is deducted in calculating the final payment to be made by Schofields to obtain its 50 percent interest.
61It is difficult to understand the commercial purpose behind this provision. Schofields produced various worked examples to demonstrate that, on certain assumptions, the formula has a sensible commercial operation, although its analysis depends on assessing the amount payable under cl 4.4(b) as at the date of payment, not the date of Planning Approval. On that interpretation, if Dairycorp complies with its contractual obligations, it will have repaid the NAB loan, "LA" in the formula will be zero and, leaving interest aside, Dairycorp will be entitled, in effect, to receive 50 percent of the value of the land (although not necessarily 50 percent of the value of the land as at the date Planning Approval is granted). Also on that interpretation, the commercial rationale of the provision is to operate as a penalty in the event that Dairycorp fails to repay the NAB debt in accordance with cl 11(a) of the JVA, or, at least, an inducement for Dairycorp to do so, since the reduction is only made if Dairycorp has failed to repay the NAB debt at the time the advance is made. This interpretation avoids the more extreme results of the clause, although it is not clear why the penalty or inducement is proportional to the amount that Schofields has already advanced. That amount bears no relationship to the prejudice suffered by Schofields as a result of any delay or failure by Dairycorp to repay the NAB loan. Moreover, it is difficult to understand why "I" is to be deducted when the interest advanced by Schofields is already taken into account in calculating Schofields' participating interest.
62On the other hand, it is equally difficult to understand the commercial rationale of the provision if, once Planning Approval is obtained, the joint venture becomes responsible for the NAB debt. In that event, the reduction in the amount that Schofields must pay under cl 4.4(b) by reference to the NAB debt may be small, but, however small it is, Schofields must also assume liability for half the NAB debt in order to acquire its 50 percent interest in the joint venture. In that event, it will pay substantially more than 50 percent of the value of the land to acquire a 50 percent interest; and the reduction that cl 4.4(b) requires to be made to take account of existing debt cannot be understood as compensation for the fact that Schofields must assume half the NAB debt.
63In my opinion, cl 4.4(b) sheds little light on the parties' intention in relation to the question who would be responsible for repayment of the NAB debt following the granting of Planning Approval. It is difficult to say that the commercial purpose of the clause was to do anything more than fix part of the price that Schofields had to pay in order to acquire an interest in the land and joint venture. It may have made commercial sense for that price to be calculated by reference to the value of the land. But that is not the only approach the parties could have taken. The plaintiffs were contributing the land to the joint venture. Schofields was contributing its expertise. How those different contributions were to be valued was a matter for negotiation. The parties were each represented by experienced solicitors, and the result of the negotiations included cl 4.4(b).
64The plaintiffs point to a number of other provisions of the JVA which they say support their construction of cl 11. However, in my opinion, the provisions that the plaintiffs point to cannot alter the clear meaning of cl 11(b), and most of them are equivocal. For example, the definition of "External Loan Funds" includes a loan "in respect of which the Joint Venture Parties become severally liable ... after the Planning Approval is obtained". That definition is sufficiently wide to cover the NAB debt of the plaintiffs' interpretation of cl 11 of the JVA. But I do not think that the definition is inconsistent with Schofields' interpretation. The plaintiffs put emphasis on the fact that the terms of the refinancing of the NAB debt required Schofields' approval. But that requirement can be explained by the fact that Schofields was required to make various repayments calculated by reference to the amounts payable under that facility, were required if necessary to give a limited guarantee in respect of it and had step-in rights in the event of a default by the plaintiffs. The plaintiffs also point to cl 17.3 of the JVA, which provides that any compensation received in respect of the compulsory acquisition of the "TIDC Land" would be applied to the repayment of the NAB debt or interest on that debt as determined by the joint venture committee. The "TIDC Land" is part of the land shown on a Deposited Plan. The plaintiffs submit that the parties would not have agreed to apply that compensation towards the NAB loan unless Schofields was to become responsible for half of it. However, I do not think that follows. Clause 17.3 applies whether or not Planning Approval was obtained and whether compulsory acquisition occurred before or after that time. The significance of the provision is difficult to gauge without knowing the likely value of the land the subject of compulsory acquisition. But there is no reason why the provision should not simply be regarded as part of the consideration agreed by Schofields in order to obtain a 50 percent interest in the land and joint venture.
65There are two other provisions of the JVA that support Schofields' interpretation of cl 11.
66First, cl 2(d) states that Schofields is under "no obligation to assume any liability under Dairycorp's existing debt facility (or any refinance of that existing debt facility)". The plaintiffs submit that cl 2(d) is only concerned with the position prior to the granting of Planning Approval. However, the clause does not say so, and the reference to any refinance of the existing debt facility suggests that the clause was intended to have a continuing operation.
67Second, cl 4.3(a) states that it is the intention of the parties "to fund all Joint Venture Costs, whether before or after the date that Planning Approval is obtained by way of External Loan Funds". The JVA contains an extensive definition of "Joint Venture Costs". However, that definition does not include the costs of paying out the plaintiffs' existing debt secured against the property. It is to be expected that the parties would have said that the Joint Venture Costs would include an amount to pay out the plaintiffs' existing facility if that is what they intended.
68It follows that the plaintiffs' claim based on the correct construction of the JVA must be rejected.
