The proper construction of the Settlement Agreement
34 The appellant's argument is a simple one: the terms of the Settlement Agreement as contained in the email of 12.15pm on 8 March (as amended during the course of the afternoon) did not contain any express release by the appellant of the claims that he made in his Cross-Claim and there is no basis for implying such a release. It was submitted on his behalf that the continued availability of such claims was expressly recognised by subparagraphs 4(xiv) and 4(xv).
35 I do not accept this argument. When the documents passing between the parties on 7 and 8 March are looked at as a whole, as I consider they must be, it is in my view clear that the parties to the building agreement intended to release each other from all claims in relation to the agreement that arose out of circumstances then known to both parties.
36 Whilst the terms of the 12.15pm email (as amended) set out the points of agreement between the parties, it is necessary to have regard to the preceding communications on 7 and 8 March to identify the commercial purpose and subject matter, that is the disputes and claims, to which the points of agreement in the 12.15pm email were intended to relate.
37 Even if the terms set out in the 12.15pm email of 8 March (as subsequently amended) are regarded as a comprehensive statement of the parties' bargain, it is permissible to have recourse to the earlier communications for this purpose. Many authorities establish this principle. One statement of it is that of Gleeson CJ International Air Transport Association v Ansett Australia Holidays Limited [2008] HCA 3; (2008) 234 CLR 151 as follows:
"8. In giving a commercial contract a businesslike interpretation, it is necessary to consider the language used by the parties, the circumstances addressed by the contract, and the objects which it is intended to secure ( McCann v Switzerland Insurance Australia Ltd [[2000] HCA 65;] (2000) 203 CLR 579 at 589 [22]; Lake v Simmons [1927] AC 487 at 509 per Viscount Sumner). An appreciation of the commercial purpose of a contract calls for an understanding of the genesis of the transaction, the background, and the market ( Pacific Carriers Ltd v BNP Paribas [[2004] HCA 35;] (2004) 218 CLR 451 at 462 [22]; Reardon Smith Line Ltd v Yngvar Hansen-Tangen [1976] 1 WLR 989 at 995-996; [1976] 3 All ER 570 at 574; Codelfa Construction Pty Ltd v State Rail Authority (NSW) [[1982] HCA 24;] (1982) 149 CLR 337 at 350). This is a case in which the Court's general understanding of background and purpose is supplemented by specific information as to the genesis of the transaction. The Agreement has a history; and that history is part of the context in which the contract takes its meaning ( Singh v The Commonwealth [[2004] HCA 43;] (2004) 222 CLR 322 at 331-338 [8]-[23]) …".
38 The following matters emerge from consideration of the preceding communications on 7 and 8 March.
39 The opening email, being that which the appellant sent at 4.10pm on 7 March, referred to the "settlement of all previous invoices and all currently identified rectifications except for the roof, gutters and overflow which are to be addressed within a specified time". To my mind this statement suggested that the appellant intended that the proposed settlement would preclude further claims in respect of already identified defects (including at least those included in the architects' list of 25 February 2005, of which both parties were by then aware). From the absence of any inconsistent assertions by Cabport in its subsequent emails, it can be concluded that these subsequent communications involved at least implicit acceptance by Cabport of this object of the contemplated settlement. The subsequent emails from the appellant to which reference is made below involved at least implicit re-affirmation by the appellant of that object.
40 Secondly, the appellant's email of 10.24am on 8 March indicated that he regarded his disputes with the builder as being brought to an end by the settlement. Bearing in mind that the parties' communications on 7 and 8 March included consideration of what was to be done about defects that had been identified, it was implicit that the appellant intended that the settlement cover claims in respect of all of the then identified defects.
41 Thirdly, the appellant's reference at the beginning of his email sent at 12.15pm on 8 March to the "resolution of our differences regarding the building works" at the property suggested a broad ranging settlement of all existing disputes and claims in respect of defects which had at that time been identified.
42 Fourthly, the email sent by the appellant at 5.47pm on 8 March (see [30] above) indicated that Cabport was to discount its invoices by $20,000 for "invoice discrepancies", that is, in effect alleged overcharges and by $10,000 for rectification of identified defects other than roof, gutters and overflow.
43 Subparagraphs 4(xiv) and (xv) of the 12.15pm email (as amended) suggested that some rights of action of the appellant were intended to be preserved. Bearing in mind the aspects of the email communications to which I have just referred, those subparagraphs should in my view be understood as preserving only claims arising out of matters of which the parties (and in particular the appellant) were unaware at the time of settlement and which were not therefore the subject of the existing disputes.
44 This approach is supported by the specific provisions made in subparagraphs 4(iv), (v) and (xiii). When account is taken of the object of the Settlement Agreement as being to settle the existing disputes between the parties and account is taken of the earlier communications, the effect of those subparagraphs so far as defects in the works are concerned is in my view as follows:
- The appellant forgoes any rights in respect of the work defects that have been identified to that time, other than the roofing defects. The appellant forgoes these rights because Cabport has allowed a discount from its invoices to cover the cost of remedying those defects (see [30] above);
- Roofing defects that have been identified are dealt with separately in subparagraph 4(v) (hence the words "subject to 4(v)" in 4(xiii)). Pursuant to 4(v), Cabport is to have the roofing defects remedied; and
- In respect of any defects for which subcontractors, as distinct from Cabport itself, are responsible and which are identified after the date of the Settlement Agreement, Cabport promises to do what it can to have the subcontractors remedy those defects. This might involve Cabport enforcing any relevant rights of action it might have against the subcontractors.
45 The statutory warranties referred to in subparagraph 4(xiv) are found in s 18B of the Home Building Act 1989. The performance by a builder of defective work, or delay in performance, would constitute a breach of those warranties. For the reasons given in [43] above, subparagraph 4(xiv) should be read, so far as it relates to defective work, only to defects identified after the date of the Settlement Agreement. The position is likewise in respect of delayed performance. It is not easy to conceive of delayed performance of which the appellant was not aware at the date of the Settlement Agreement but, be that as it may, it would only be claims in respect of delayed performance of that type that would be preserved by subclause 4(xiv).
46 In summary, the Settlement Agreement was in my view intended to settle all the disputes that then existed between the parties. These extended to the overcharging allegedly embodied in Cabport's invoices and to defects in the building work that had by then been identified. Subject to the specified exceptions referred to in [44] above, the Agreement implicitly involved the parties foregoing any claims that arose or might arise out of aspects of the performance or non-performance of the building contract of which they were aware at the time of the Settlement Agreement.
47 The conclusion that I have reached is consistent with the approach of the High Court in Grant v John Grant & Sons Proprietary Ltd [1954] HCA 23; (1954) 91 CLR 112 where general words in a release clause were held not to extend to a liability of the defendant of which the plaintiff was unaware. Dixon CJ, Fullagar, Kitto and Taylor JJ said in that case:
"From the authorities which have already been cited it will be seen that equity proceeded upon the principle that a releasee must not use the general words of a release as a means of escaping the fulfilment of obligations falling outside the true purpose of the transaction as ascertained from the nature of the instrument and the surrounding circumstances including the state of knowledge of the respective parties concerning the existence, character and extent of the liability in question and the actual intention of the releasor.
The facts stated in the third replication if true would show that the plaintiff company did not know of the defendant's liability it now seeks to enforce, did not intend to release it as part of the transaction and did not know of any intention on the part of the defendant that it should be released" (at 129 - 130).
