Arguments based on contract law
91Mr Soltan submitted that the Tribunal made a number of errors in its application of principles of contract law. They related, he claimed, to its treatment of the Payment Plan Agreement as binding on the parties and to its decision that the rent stated in this Agreement was agreed by the parties to be the current market rent. We will deal with these two subject-matters separately.
92Whether the Payment Plan Agreement was binding. Mr Soltan submitted that despite the apparent acceptance by the Applicant of the terms of this Agreement (as evidenced in Mr Richerdson's email to Mr Condell dated 24 October 2012), it was in fact not binding on the parties, by virtue of the failure of either or both of two conditions subsequent contained in it.
93The first of these conditions derived, he said, from Mr Condell's statement in his email of 16 October 2012 to Mr Richerdson that he had 'discussed this proposal with the owners and they will only agree to this payment plan if it is strictly adhered to'. According to Mr Soltan, this statement incorporated into the Agreement a condition of 'strict adherence' with which the Applicant did not comply. Its non-compliance took the form of failing to make the payments of current arrears stipulated in the Payment Plan, with the consequence that as late as March 2013 the Respondents drew down on its bank guarantee, thereby receiving the sum of $71,250.
94We are singularly unimpressed by this argument. It appears to imply that so long as the Applicant maintained the payments required by the Plan it would be bound by the Agreement, but as soon as it defaulted it would no longer be bound. Furthermore, to interpret this statement in Mr Condell's email as designed to import a condition subsequent into the proposed Agreement is to misunderstand its role completely. The message from the Respondents that this statement was intended to convey was simply that they would be likely to enforce strictly the rights reserved to them under the Lease if the Applicant defaulted in making the required payments.
95The second condition subsequent that Mr Soltan claimed to have been present in the Agreement derived from the last sentence in Mr Condell's email of 16 October 2012. This was as follows: 'If we can reach an arrangement, I will draft a more formal agreement for you to agree to.' Mr Soltan submitted that this constituted a condition subsequent, which was not satisfied because neither Mr Condell nor anyone else on behalf of the Respondents sent a 'more formal agreement' to the Applicant for it to 'agree to'.
96In this context, Mr Soltan invoked the authority of the well-known High Court case of Masters v Cameron (1954) 91 CLR 353, arguing that the Payment Plan Agreement fell into the third category of putative contracts outlined in this decision, not (as the Tribunal had held) in the first category.
97The passages in Masters v Cameron on which he relied were paragraphs [9] to [12], [19] and [20] (at pp 360-363 and 366-367 of the report):-
9. Where parties who have been in negotiation reach agreement upon terms of a contractual nature and also agree that the matter of their negotiation shall be dealt with by a formal contract, the case may belong to any of three cases. It may be one in which the parties have reached finality in arranging all the terms of their bargain and intend to be immediately bound to the performance of those terms, but at the same time propose to have the terms restated in a form which will be fuller or more precise but not different in effect. Or, secondly, it may be a case in which the parties have completely agreed upon all the terms of their bargain and intend no departure from or addition to that which their agreed terms express or imply, but nevertheless have made performance of one or more of the terms conditional upon the execution of a formal document. Or, thirdly, the case may be one in which the intention of the parties is not to make a concluded bargain at all, unless and until they execute a formal contract. (at p360)
10. In each of the first two cases there is a binding contract: in the first case a contract binding the parties at once to perform the agreed terms whether the contemplated formal document comes into existence or not, and to join (if they have so agreed) in settling and executing the formal document; and in the second case a contract binding the parties to join in bringing the formal contract into existence and then to carry it into execution. Of these two cases the first is the more common. Throughout the decisions on this branch of the law the proposition is insisted upon which Lord Blackburn expressed in Rossiter v. Miller (1878) 3 App Cas 1124 when he said that the mere fact that the parties have expressly stipulated that there shall afterwards be a formal agreement prepared, embodying the terms, which shall be signed by the parties does not, by itself, show that they continue merely in negotiation. His Lordship proceeded: " . . . as soon as the fact is established of the final mutual assent of the parties so that those who draw up the formal agreement have not the power to vary the terms already settled, I think the contract is completed" (1878) 3 App Cas, at p 1151: see also Sinclair, Scott & Co. Ltd. v. Naughton [1929] HCA 34; (1929) 43 CLR 310, at p 317...
11. Cases of the third class are fundamentally different. They are cases in which the terms of agreement are not intended to have, and therefore do not have, any binding effect of their own: Governor & c. of the Poor of Kingston-upon-Hull v. Petch [1854] EngR 995; (1854) 10 Exch 610 (156 ER 583). The parties may have so provided either because they have dealt only with major matters and contemplate that others will or may be regulated by provisions to be introduced into the formal document, as in Summergreene v. Parker [1950] HCA 13; (1950) 80 CLR 304 or simply because they wish to reserve to themselves a right to withdraw at any time until the formal document is signed. These possibilities were both referred to in Rossiter v. Miller (1878) 3 App Cas 1124. Lord O'Hagan said: "Undoubtedly, if any prospective contract, involving the possibility of new terms, or the modification of those already discussed, remains to be adopted, matters must be taken to be still in a train of negotiation, and a dissatisfied party may refuse to proceed. But when an agreement embracing all the particulars essential for finality and completeness, even though it may be desired to reduce it to shape by a solicitor, is such that those particulars must remain unchanged, it is not, in my mind, less coercive because of the technical formality which remains to be made" (1878) 3 App Cas, at p 1149 . And Lord Blackburn said: "parties often do enter into a negotiation meaning that, when they have (or think they have) come to one mind, the result shall be put into formal shape, and then (if on seeing the result in that shape they find they are agreed) signed and made binding; but that each party is to reserve to himself the right to retire from the contract, if, on looking at the formal contract, he finds that though it may represent what he said, it does not represent what he meant to say. Whenever, on the true construction of the evidence, this appears to be the intention, I think that the parties ought not to be held bound till they have executed the formal agreement" (1878) 3 App Cas, at p 1152 . So, as Parker J. said in Von Hatzfeldt-Wildenburg v. Alexander (1912) 1 Ch 284, at p 289 in such a case there is no enforceable contract, either because the condition is unfulfilled or because the law does not recognize a contract to enter into a contract. (at p362)
12. The question depends upon the intention disclosed by the language the parties have employed, and no special form of words is essential to be used in order that there shall be no contract binding upon the parties before the execution of their agreement in its ultimate shape: Farmer v. Honan [1919] HCA 13; (1919) 26 CLR 183. Nor is any formula, such as "subject to contract", so intractable as always and necessarily to produce that result: cf. Filby v. Hounsell (1896) 2 Ch 737...
19. The third question refers to conduct of the male appellant after 6th December 1951 and before he finally refused to proceed with the purchase. By this conduct the respondent asserts that she was led to believe that a binding contract of sale and purchase existed between the appellants and herself and was led in that belief to change her own position substantially. He requested the respondent's sons, and they complied with the request, to leave work they were doing on the fencing of the property in the manner required by the signed document, and to help him clean up timber which had fallen as a result of a fire on the property. He took possession of a room in the house and brought some of his goods on to the property. He effected some structural alterations and additions to the house. He put down superphosphate and seed on the land and erected a tank, employing labour for the purpose. During all this time he was insisting upon the respondent being ready to hand over exclusive possession of the property on the date mentioned in the document, 15th March 1952; and in order to be in a position to do so she sold her sheep and bought a house in Perth.
20. It was certainly most unfortunate for the respondent that after all this the appellants should be at liberty to turn round, as they did when they encountered financial difficulties which had nothing to do with the respondent, and deny that they were legally bound to purchase "Bokhara". But their liberty to do this arose from the fact that the respondent had herself introduced the qualifying sentence into her portion of the document of 6th December 1951; and it may be remarked in passing that according to Way's evidence she had done so very deliberately, with an eye to the fact that the property had come to her under a will and she felt a need to consult her solicitor before completing a formal contract. Whilst undoubtedly the male appellant's conduct showed that he confidently expected the transaction to go through and realized that the respondent had a like expectation, it plainly could not have been intended by him or relied upon by the respondent as a representation that there was any other relationship between them than that which was to be found within the four corners of the agreement of 6th December 1951. The question as to estoppel must be answered in favour of the appellants.
98Relying in particular on the last two paragraphs, Mr Soltan argued that the Tribunal erred in stating that acts appearing to constitute partial performance of an alleged agreement may point towards the conclusion that it falls within the first of the Masters v Cameron categories. He quoted the following sentence of the Tribunal's decision at [23]: 'The parties carried the payment plan agreement into execution for the 2012-2013 lease year and it is not now to the point that a formal version of the agreement was not produced.'
99A further submission of Mr Soltan was that the Tribunal also erred (again at [23]) in stating that the Applicant's submission based on Masters v Cameron was 'contrary to Mr Soltan's position (and Mr Richerdson's) to the effect that while there is a dispute as to its extent, an agreement was made in respect of the payment plan'. He maintained that the Tribunal should instead have assessed the intention of the 'proponent' of the Agreement, Mr Condell, on the basis of the words that Mr Condell used.
100Mr Ireland's arguments in response to these contentions were that the Tribunal's analysis of this issue disclosed no error and that we should take account of two passages in the transcript of the Tribunal hearing on 4 November 2013. In the first of these (p 2, line 49, to p 3, line 15), Mr Soltan conceded, 'just to make everybody comfortable', that his client 'agreed to the payment plan', and repeated this concession when asked by DP Callaghan to make his position clear. At the end of the second passage (p 17, lines 38 to 50), DP Callaghan referred to this concession immediately after Mr Ireland had made the submission that Mr Richerdson, in his witness statement, acknowledged his acceptance of the Agreement.
101On this question, our interpretation of the correspondence constituting the Payment Plan Agreement accords with that of the Tribunal. The statement by Mr Condell on which Mr Soltan relied must be considered alongside the accompanying Payment Plan, which specified in detail the times and amounts of the payments expected to be made by the Applicant and the effect that these payments would have over five months in reducing the arrears of rent. It is significant also that the date of commencement of the Plan was specified as 1 October 2012, eleven days earlier than the email containing Mr Condell's statement. This is another factor suggesting that the parties intended the Agreement to be binding on them as soon as the Applicant's acceptance was communicated to the Respondents or their agent.
102Applying the principles stated in the passages that we have quoted from Masters v Cameron, we are accordingly satisfied that the Tribunal did not err in its classification of the Agreement. The fact that Mr Soltan made a concession during the Tribunal hearing in line with this classification supports this conclusion, but we would have arrived at it in any event.
103Whether the parties reached agreement as to the current market rent. In his submissions, Mr Soltan challenged each of the grounds on which the Tribunal decided that the rent stated in the Payment Plan Agreement was agreed by the parties to be the current market rent. He argued that the Tribunal erred in basing this decision on each of the following alternative grounds: (a) the express terms of the Agreement; (b) the 'inferred intention' of the parties; (c) an implied term; and (d) a 'supplementary agreement'. We will discuss each of these four alleged errors separately.
104The express terms of the Agreement. Citing paragraph [34] (which we have reproduced above at [79]) of the decision in Alma Constructions Pty Ltd v C. D. Management Group Pty Ltd [2008] NSWADT 3, Mr Soltan argued that in the Payment Plan Agreement there was no express agreement as to the current market rent because there was no 'meeting of the minds' of Mr Condell and Mr Richerdson. He added that the Tribunal itself recognised at [17] that a term of this nature was 'not explicit, at least in those actual words'. The Tribunal in fact pointed out that the Agreement did not set out monthly rent payments for the whole of the final year of the Lease or use the phrase 'current market rent'. Since this particular aspect of the Agreement was 'unambiguous', he maintained, the Tribunal should not have taken into account the 'surrounding circumstances' of the Agreement, or the context in which it was made, or the subsequent conduct of the parties.
105In the alternative, Mr Soltan argued that if we agreed with the Tribunal's statement (at [18]) that the Agreement was in fact ambiguous and for that reason considered it appropriate to take surrounding circumstances into account, we should still conclude that there was no agreement that the rent stipulated was the current market rent. This was for the following reasons: (a) Mr Richerdson testified that when conveying acceptance of the Payment Plan Agreement, he did not regard it as dealing with the current market rent; (b) the Respondents did not call Mr Condell as a witness; (c) we should therefore infer, as the Tribunal should have done, that he too would have said that he did not believe the Agreement to be concerned with current market rent.
106In response, Mr Ireland argued that at the time when the Applicant accepted the terms of the Payment Plan Agreement, the officers and agents acting on its behalf must be taken to have been aware of the relevant provisions of the Lease, including particularly clause 15. Accordingly, it was irrelevant that one such agent, Mr Richerdson, testified that he was not aware of them. In support of this proposition, Mr Ireland cited a statement by Young CJ in Eq in Zucker v Straightlace Pty Ltd (1986) 11 NSWLR 87 and the High Court's decision in Toll (FGCT) Pty Ltd v Alphapharm Pty Ltd (2004) 219 CLR 165.
107In Zucker, the statement (at pp 92-93) is as follows: 'It is also quite clear that where a purchaser's right to rescind depends upon contract that (sic), as a person is deemed to know what is in the contract he himself made, knowledge of a fact which the contract permits as the basis of rescission is sufficient without a realisation by the person that that right exists.'
108In Toll, Mr Ireland relied particularly on paragraphs [45] and [46] of the joint judgment of the Court. It is sufficient here to quote the following extracts from these paragraphs:-
45 It should not be overlooked that to sign a document known and intended to affect legal relations is an act which itself ordinarily conveys a representation to a reasonable reader of the document. The representation is that the person who signs either has read and approved the contents of the document or is willing to take the chance of being bound by those contents... whatever they might be...
46. The statements in the above authorities accord with the well-known principle stated by Scrutton LJ in L'Estrange v F Graucob Ltd... that "[w]hen a document containing contractual terms is signed, then, in the absence of fraud, or, I will add, misrepresentation, the party signing it is bound, and it is wholly immaterial whether he has read the document or not."
109Mr Ireland also relied on what the High Court in Toll (at [40]) called 'the principle of objectivity by which the rights and liabilities of the parties to a contract are determined'. He drew to our attention the Court's reaffirmation of this principle in a decision, Electricity Generation Corporation v Woodside Energy Ltd [2014] HCA 7, delivered as recently as 5 March 2014. At paragraph [35] of that decision, the Court said (footnotes are omitted):-
35... this 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"[39]. 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".
110By virtue of this principle, he submitted, the 'surrounding circumstances' that could properly be taken into account in construing any ambiguities in the Payment Plan Agreement would not include Mr Richerdson's subjective knowledge or intentions (or indeed those of Mr Condell) at the time when the Plan was agreed on. The fact that these individuals were agents of the parties, not the parties themselves, provided additional support for this proposition.
111In our opinion, one important and indeed obvious aspect of the situation existing during the period when the Payment Plan Agreement was proposed by the Respondents' agent and accepted by the Applicant's agent was not sufficiently emphasised in the Tribunal's decision or the parties' submissions. It is that this Agreement does not stand alone. It does not make legal or commercial sense unless it is read in conjunction with the Lease.
112Accordingly, there is a strong case for concluding that the appearance of the amount $31,827.27 beside the phrase 'Rental amounts' in the Payment Plan, when considered alongside Items 13.A and 16 and clause 5 of the Lease, signified that although neither of the parties had utilised the procedure for determining current market rent set out in clauses 5.13 to 5.15, the Respondents were now proposing this figure of $31,827.27 as the 'current market rent', payable throughout the final year of the Lease. If the monthly rent stated had been the same as was payable during the preceding year (18 August 2011 to 17 August 2012), this interpretation would not be available. But the proposed rental incorporated a 5% increase.
113Applying the criteria stated in the passage in Electricity Generation that we have just reproduced, we therefore see considerable merit in the view that a 'reasonable businessperson' would have attributed this meaning to the Payment Plan's stipulation of an increased rental, considered side by side with the relevant parts of the Lease. This is the case irrespective of whether the provisions of the Agreement under consideration should be characterised as ambiguous (which we believe to be the correct view) or unambiguous.
114It was of course open to Mr Richerdson, whether acting on his own initiative or under instructions from Mr Gebara, to claim that this figure of $31,827.27 did not represent current market rent and therefore did not have to be accepted by the Applicant. But Mr Richerdson did not do this. In his email response to Mr Condell, he simply accepted the 'payment proposal' unconditionally. It is strongly arguable that the 'reasonable businessperson' would be likely to infer from this that on behalf of the Applicant he agreed that this figure should be taken to represent current market rent and was therefore payable pursuant to items 13.A and 16 and clause 5 of the Lease.
115Having regard to the High Court's firm adherence to the principle of objectivity in interpreting contracts, the evidence indicating or suggesting that Mr Richerdson (and possibly also Mr Gebara: see the last paragraph of the Tribunal's summary of his evidence, quoted above at [25]) had forgotten, or were never aware of, the role played by current market rent in the Lease must be regarded as irrelevant. The same must be said of any inference, such as Mr Soltan invited us to draw, of ignorance of these matters on the part of the Respondents' agent. There was no evidence at all as to whether any of the Respondents themselves were aware at any time of this aspect of the Lease.
116The foregoing conclusions on this quite difficult question of interpretation are put forward only as more likely to be correct than the opposing position advanced by Mr Soltan - i.e. that because the Payment Plan Agreement made no reference to current market rent, the parties to it agreed only that the rent stipulated in it should be paid 'on account' until the current market rent, being the rent properly payable, had been agreed upon or determined by a valuer. We do not present these conclusions as the final basis on which we have decided this appeal because, for reasons explained below, we are clearly satisfied as to the correctness of a further ground on which the Tribunal found in favour of the Respondents.
117An 'inferred intention'. We have singled out this element of the Tribunal's decision as a matter requiring separate attention, even though the 'inferring' of the parties' 'intention' appears to us to be closely linked with the process of construing the express terms of an agreement. The principal reason why we treat this topic separately is that Mr Soltan advanced submissions specifically addressing it.
118His challenge to this aspect of the Tribunal's reasoning was based in part on the fact that relevant passages in the case on which the Tribunal chiefly relied at this point, Franklins Pty Ltd v Metcash Trading Ltd (2009) 76 NSWLR 603; [2009] NSWCA 407, had been criticised to some extent in subsequent decisions.
119Any doubts on this matter must, however, be regarded as resolved by the High Court in Electricity Generation Corporation v Woodside Energy Ltd [2014] HCA 7. For present purposes, the Court's statement of principle at [35], quoted above at [109], does not differ materially from the passage (at [19]) that the Tribunal quoted from the Franklins decision.
120Mr Soltan argued also that the Tribunal 'erroneously misapplied' to the facts of the present case two phrases that appear in more or less identical form in both Franklins and Electricity Generation: namely, 'the commercial purposes of the transaction' and 'the genesis of the transaction, the background, the context [and] the market in which the parties are operating'.
121With respect to these matters he made the following submissions: (a) the genesis of the Payment Plan Agreement was the existence of substantial arrears of rent; (b) its commercial purpose was to deal with these arrears; (c) its background included (i) the incorrect invoicing of rent, 'automatically' increased by 5% since 18 August 2012, by the Respondent's agent, (ii) the failure of both parties to invoke the rent review provisions of the lease and (iii) the absence of any evidence of knowledge of these provisions by the parties' agents; and (d) the context and market in which the parties operated included a standard practice among commercial managing agents of advising lessees just before or after a rent review date of the amount at which the lessor had assessed the current market rent.
122According to Mr Soltan, the Tribunal erred in failing to take these matters into account when determining the 'inferred intention' of the parties.
123In support of his arguments on this topic, Mr Soltan cited two paragraphs, [2-40] and [2-44] of Carter, The Construction of Commercial Contracts.
124It is true that the Tribunal did not describe as 'automatic' the 5% increase in the rent occurring under the Payment Plan Agreement. Mr Soltan suggested to us that it was in fact generated 'automatically' by a computer in TGC's office. But there is no evidence that this is how it occurred.
125It is true also that the Tribunal did not refer to what he claimed to be a 'standard practice' among commercial managing agents. We do not believe, however, that the existence of any such practice is necessarily a relevant factor in determining the particular question of construction that we are now considering.
126Contrary to Mr Soltan's submission, the Tribunal did refer in its decision to all the other matters that we have listed at [121]. There is no reason to believe that it did not also take them into consideration when applying the principles that it quoted from Franklins v Metcash.
127As we pointed out to Mr Soltan during the hearing, the two paragraphs from Carter, The Construction of Commercial Contracts, that he drew to our attention do not relate to 'inferred intention' in determining the meaning of contractual terms. Instead, they relate respectively to the question whether a pre-contractual statement forms part of the contract and to the classification of terms as conditions or warranties.
128For these reasons, we reject Mr Soltan's challenge to the Tribunal's decision in so far as it invoked the concept of 'inferred intention'.
129An implied term. Mr Soltan argued that the Tribunal erred at [19] in deciding that a term should be implied in the Payment Plan Agreement to the effect that the rent stated in it was the current market rent. He maintained that none of the requirements for such a term that the High Court outlined in the case cited by the Tribunal, B.P. Refinery (Westernport) Pty Ltd v Hastings Shire Council (1977) 52 ALJR 20, was in fact satisfied.
130The specific points that he made in his written submissions about a term to this effect were as follows:-
(1) It was not 'reasonable and equitable' because (i) it deprived the Applicant of its contractual and statutory right to have the current market rent determined by a specialist retail valuer; (ii) at the time when it would be implied, Mr Richerdson was not aware of the rent review provisions of the Lease; (iii) it was implied after incorrect invoicing of rent by the Respondents' agent; and (iv) the Applicant could not dispute the Respondents' position on this matter because it was at risk of being evicted.
(2) It was not 'necessary to give business efficacy' because the desired effect of the Payment Plan Agreement would be achieved without its being treated as bearing on the current market rent.
(3) It was 'not so obvious within' the Agreement and the emails between Mr Condell and Mr Richerdson.
(4) There was no 'clear expression' of it within the Agreement.
(5) It 'contradicted an express term' of the Agreement, namely, the provision that if the parties did not agree on the current market rent, it should be determined by a valuer.
131Mr Ireland did not address the question of an implied term to any significant extent.
132In our opinion, the first of these five contentions is not made out and the third and fourth appear to be based on misunderstandings of the criteria stated by the High Court. But there is merit in the second and fifth contentions. The Agreement would not have lacked 'business efficacy' simply because it did not purport to resolve the question of current market rent and, on the face of it at least, the suggested implied term did contradict an express term of a contract (the Lease) which we have held to be closely associated with the Agreement.
133For these reasons, we incline to the view that the Tribunal's ruling that an implied term arose within the Agreement was subject to error. As the Tribunal pointed out, however, this ruling was not essential to its decision in favour of the Respondents.
134A 'supplementary agreement'. In his written submissions, Mr Soltan argued that the Tribunal erroneously applied the passage that it quoted from Branir Pty Ltd v Owston Nominees (No 2) Pty Ltd (2001) 117 FCR 429 (we have quoted this passage above at [46]), for the following four reasons.
135First, the current market rent was a 'commercial essential', indeed the 'focal point' in the relations between the parties. But it was never discussed by them. Secondly, there was no clear basis for inferring a 'manifest mutual assent' between them, since the evidence showed instead that they simply overlooked it. Thirdly, 'implication or inference as stated earlier reveals no agreement'. Fourthly, statements indicating an awareness of the market review date of 18 August 2012 were never made by either party until the Applicant filed its Application on 16 August 2013.
136In his oral submissions, Mr Soltan argued that another reason why there was no 'mutual assent' between the parties that the new lease arising out of the Applicant's exercise of the option to renew had not been executed by it.
137Mr Soltan relied in this context on a Supreme Court case, Callaghan v Merivale CBD Pty Ltd [2005] NSWSC 985. Here a lessee sued successfully to recover overpaid rent, which the lessor had demanded without being entitled to do so. The passage in the judgment (at [27]) on which Mr Soltan placed particular emphasis was as follows:-
27 What the circumstances do indicate, rather than an agreement to accept the rent fixed by the lessor, is a misrepresentation (doubtless innocent), made on its behalf, that in the events that had happened the rent had been effectively fixed at the revised figure which could not be reconsidered under clause 6(c). The payments of the increased amounts made in consequence by the lessee were made under a mistake induced by that misrepresentation, and are recoverable...
138In submitting that the Tribunal, at [20], had stated and applied the law correctly in finding (as an alternative ground) that a 'supplementary agreement' had arisen out of the parties' of conduct, Mr Ireland relied on passages in the Court of Appeal's decision in Brambles Holdings Limited v Bathurst City Council (2001) 53 NSWLR 153; [2001] NSWCA 61. The issue in that case was whether the respondent Council was entitled to require the appellant company, with which it had a contract for waste disposal, to remit to it a proportion of liquid waste fees that the appellant collected from third parties. In upholding the trial judge's decision in favour of the Council, the Court held that the appellant, by its conduct, had impliedly accepted an offer by the Council which included provision for the partial remission of these fees.
139The passages in the judgments on which Mr Ireland relied included the following extracts from the judgment of Heydon JA:-
74 Thus offer and acceptance analysis is a useful tool in most circumstances, and indeed is "normal" and "conventional" (Gibson v Manchester City Council [1979] 1 All ER 972 at 974 per Lord Diplock). But limited recognition has been given to the possibility of finding that contracts exist even though it is not easy to locate an offer or acceptance. In Integrated Computer Services Pty Ltd v Digital Equipment Corp (Aust) Pty Ltd (1988) 5 BPR [97326] at 11,117-11,118 McHugh JA (Hope and Mahoney JJA concurring) said:
"It is often difficult to fit a commercial arrangement into the common lawyers' analysis of a contractual arrangement. Commercial discussions are often too unrefined to fit easily into the slots of 'offer', 'acceptance', 'consideration' and 'intention to create a legal relationship' which are the benchmarks of the contract of classical theory. In classical theory, the typical contract is a bilateral one and consists of an exchange of promises by means of an offer and its acceptance together with an intention to create a binding legal relationship ...
Moreover, in an ongoing relationship, it is not always easy to point to the precise moment when the legal criteria of a contract have been fulfilled. Agreements concerning terms and conditions which might be too uncertain or too illusory to enforce at a particular time in the relationship may by reason of the parties' subsequent conduct become sufficiently specific to give rise to legal rights and duties. In a dynamic commercial relationship new terms will be added or will supersede older terms. It is necessary therefore to look at the whole relationship and not only at what was said and done when the relationship was first formed."
75 Those passages were cited with approval by Ormiston J in Vroon BV v Foster's Brewing Group [1994] 2 VR 32 at 82-3...
Ormiston J said at 81:
"... I am prepared to accept ... that agreement and thus a contract can be extracted from circumstances where no acceptance of an offer can be established or inferred and where the most that can be said is that a manifestation of mutual assent must be implied from the circumstances. In the language of para. 22(2) of the Second Re-statement on Contracts: 'A manifestation of mutual assent may be made even though neither offer or acceptance could be identified and even though the moment of formation cannot be determined'."
He concluded at 83:
"there is now sufficient authority to justify the court inquiring as to the existence of an agreement evidenced otherwise than by offer and acceptance."
77 One further observation of McHugh JA in Integrated Computer Services Pty Ltd v Digital Equipment Corp (Aust) Pty Ltd is relevant:
"it is an error 'to suppose that merely because something has been done then there is therefore some contract in existence which has thereby been executed'. Nevertheless, a contract may be inferred from the acts and conduct of parties as well as or in the absence of their words. The question in this class of case is whether the conduct of the parties, viewed in the light of the surrounding circumstances, shows a tacit understanding or agreement. The conduct of the parties, however, must be capable of proving all the essential elements of an express contract." ...
140Mr Ireland also cited the judgment of Ipp JA at [173]:-
173 In these circumstances, in my view, the fact that the appellant charged the higher fees is conclusive evidence that it agreed to all the conditions contained in the offer of 19 September 1991. When regard is had to the indivisible nature of the offer, the appellant's conduct, objectively viewed, was an unequivocal acceptance of the offer. The appellant accepted the benefits proposed, namely, the charging of the higher fees while using the Council's land. Those benefits could not be severed from the obligations proposed. Accordingly, by accepting those benefits the appellant accepted the Council's offer in accordance with its terms (cf Empirnall Holdings Pty Ltd v Machon Paull Partners Pty Ltd at 535).
141At the hearing, we suggested to the parties' representatives that the Applicant's 'irrevocable' exercise of the option to renew the Lease might be significant in the present context. This was effected on 15 April 2013, in a notice that was executed by the Applicant through the means of a signature supplied by Mr Richerdson. We suggested that this action could be viewed as part of a course of conduct by the Applicant signifying its acknowledgment that the rent stated in the Payment Plan Agreement was both the current market rent and the rent which, increased by 5% in accordance with the Lease, would be chargeable in the first year of the new lease.
142In response to this suggestion, Mr Soltan argued (a) that Mr Richerdson's exercise of the option could not be viewed in this light because of his evidence that he was unaware of the terms of the Lease and (b) that this exercise of the option during the permitted period of only three months was a 'commercial necessity' to keep the Applicant's business in operation.
143Mr Ireland submitted that at that time Mr Richerdson must have known the terms of the Lease, or must at least be deemed to have known them. He pointed out also that if at the time of exercise of the option the Applicant had been in breach of any term of the Lease the Respondents could have refused to grant a new lease. This consideration, he said, added to the 'unfairness' of the Applicant's conduct in seeking subsequently to depart from the parties' mutual understanding as to the amount of the rent payable.
144In our opinion, the Tribunal was correct in concluding that a supplementary agreement arose by virtue of the parties' course of conduct between the time when this agreement was concluded (October 2012) and the time when the Applicant sought to dispute this status (August 2013). This supplementary agreement confirmed the status of the rent agreed in the Payment Plan Agreement as being the rent payable during the last year of the Lease and therefore effectively the current market rent.
145We make the following additional observations. If there were any doubt as to whether a supplementary agreement of this nature had arisen by the time the option was exercised, the act of exercising it 'irrevocably' eliminated this doubt. Like the Payment Plan Agreement, the letter exercising the option was only intelligible if read in conjunction with the Lease. In particular, the rental amount initially due under the new lease, to which the Applicant conveyed its concurrence by exercising the option, was only ascertainable through consulting the terms of the Lease. The argument that the Applicant could claim not to be bound by this term of the new lease because Mr Richerdson, at the time of exercising the option, was not aware of the terms of the original Lease is simply not maintainable. Two authorities (mentioned above) that Mr Ireland cited make this clear: Zucker v Straightlace Pty Ltd (1986) 11 NSWLR 87 and Toll (FGCT) Pty Ltd v Alphapharm Pty Ltd (2004) 219 CLR 165
146The outcome of our consideration of this issue is that, subject to the arguments (outlined below) relating to the rules of natural justice, this appeal must be dismissed. Our earlier opinion that, under the express terms of the Payment Plan Agreement properly construed, the rent stated for the final year of the Lease might well have been agreed to be the current market rent was deliberately not put forward as a firm conclusion. But we are satisfied that the subsequent conduct of the parties, including particularly the Applicant's 'irrevocable' exercise of the option to renew, constituted a supplementary agreement confirming this proposition.
147An alternative way of justifying this outcome, on which we do not formally rely as it was not put before the parties, involves the following propositions: (a) the Payment Plan Agreement did not fix the rent stated in it as the agreed amount of current market rent, but simply designated it as a rental to be paid 'on account' until the current market rent had been agreed or determined; (b) the Applicant therefore remained entitled, under clause 5 of the Lease, to invoke the statutory procedure for having this rent determined by a specialist rental valuer; (c) the Applicant's decision, however, to exercise the option to renew, signifying its agreement to pay rent under the new lease at the amount stated in the Agreement plus 5%, amounted to a waiver of this right to invoke the statutory procedure and/or a deemed acceptance of the rent stated in the Agreement as the current market rent.
