Consideration of the appeal
83In considering the substantive appeal, it is important to focus upon the essential question raised by the agreement between the parties, namely CTTT Exhibit "#A5", and not extraneous matters, as I consider to have occurred in the CTTT.
84In my view, those extraneous matters were whether the Village in question was a retirement village, whether the Society had the resources to enable it to comply with the RV Act, or whether, in the circumstances, the Society should be excused from compliance with the RV Act, and like matters.
85The reason these matters should be seen to be extraneous to the true question for decision is that the construction of the agreement between the parties should first address the essential question of whether there was a binding agreement between the parties with identifiable and non-ambiguous terms.
86If that essential question is answered affirmatively, then reference to the circumstances surrounding the parties entering into the agreement, or events occurring afterwards that affected how the Village was run, becomes a superfluous and an unnecessary inquiry.
87It is only if the agreement between the parties is found to have been affected by ambiguity that justification would arise for widening the factual inquiry beyond the essential question in order to construe the agreement between the parties. In the present circumstances, the uncommunicated subjective motives or intentions of the parties are an irrelevant consideration: Toll (FGCT) Pty Limited v Alphapharm Pty Ltd & Ors [2004] HCA 52; (2004) 219 CLR 165 at [38].
88The claim by the Society that the agreement embodied a mistake must be read in the light of that statement of principle.
89I now turn to examine what I consider to be the essential question, which the CTTT Member correctly identified, namely, whether the parties had entered into a binding agreement that is caught by the RV Act: CTTT Reasons, paragraph [32].
90Turning then to the contract, it is plain from its terms that the necessary elements of a contract have been shown to exist. The parties were identified, the subject tenancy is identified, there was consideration, there was the mutual intention to create legal relations, and the contract then went on to identify the terms and conditions by which the parties agreed they would be bound.
91It is therefore irrefutable that objectively, and on its face, the contract comprising CTTT Exhibit "#A5", as formed, without the post-contractual alterations evident in the copy "corrected" by Mr Noonan, namely CTTT Exhibit "#A4", which the CTTT Member acknowledged should be ignored, contained no relevant ambiguity.
92In those circumstances, in the absence of misrepresentation or obviously communicated mistake that was obvious to Mr Butterworth, there was no justification for the CTTT looking outside the terms of the contract to construe its meaning for the purposes of identifying the mutual contractual intention of the parties at the time the contract was formed: Toll (FGCT) Pty Limited v Alphapharm Pty Ltd & Ors [2004] HCA 52; (2004) 219 CLR 165.
93On that approach, disregarding the unauthorised alterations on the copy of the agreement, which must be ignored, the only reasonable conclusion open on the construction of the contract was that the Society, which was the party that drew up the contract, intended that it be bound by the provisions of the RV Act because the provisions of the RT Act were excluded. That conclusion arises because the provisions of the RT Act were specifically excluded in the section of the document dealing with special conditions. Furthermore, that process of exclusion was permitted by s 8(1)(b) of the RT Act 2010 and s 6(1)(c1) of the RT Act 1987.
94In identifying Mr Butterworth's contractual intentions at the time he signed his agreement with the Society, it is reasonably clear on the evidence, he simply accepted the terms offered, probably without understanding the legal implications of those terms. Nevertheless, according to the objective theory of contract, he too was bound by those same terms: Toll (FGCT) Pty Limited v Alphapharm Pty Ltd & Ors [2004] HCA 52; (2004) 219 CLR 165, at [42].
95In my view, on that analysis, no further construction issues arose for consideration by the CTTT beyond that point, which effectively and conclusively defined the rights and liabilities of the parties.
96However, the CTTT Member took a different course, and considered the surrounding circumstances, and looked to the extraneous matters earlier identified. In doing so I consider that the CTTT Member reached a different, and impermissible construction, that involved several errors with respect to matters of law.
97The first such error was not to recognise that there was no relevant ambiguity in the contract between the parties. Had the CTTT Member recognised this position, that would have been the end point of any further consideration of the matter.
98The second such error was the finding recorded at paragraph [34] of the CTTT reasons, that there had been a mistake in the terms of the agreement between the parties, following which, in the remainder of the reasons, the CTTT Member sought to apply an equitable remedy seeking to rectify the purported mistake.
99Aside from the question of whether the CTTT had the requisite equitable jurisdiction to do so, there was no explicit finding classifying the type of mistake under consideration. This is a matter of some significance.
100In analysing the scope for legal classification of the finding of a mistake referred to in paragraph [34] of the CTTT reasons, it is clear that the asserted mistake was not of the kind known as common mistake. Nor did it involve any misrepresentation, fraud or any disentitling conduct on the part of Mr Butterworth that would ordinarily attract equitable relief against his interests. If anything, the asserted mistake could only then be reasonably described as being a unilateral mistake.
101For a remedy to be available to rectify a mistake of that kind, assuming the CTTT had equitable jurisdiction to rectify it, the purported mistake must be classified to fit in with the accepted principles according to the objective theory of contract, for example, as described in the following extract from Contract Law in Australia, 5th Ed, Carter JW, Peden E, Tolhurst GJ, Butterworths 2007, p 435:
"[20-13] Mistake and objective theory of contract. The primary emphasis of the law of contract in common law systems is on how one party's words and conduct ought reasonably to have been understood by the other, rather than their subjective states of mind: Taylor v Johnson [1983] HCA 5;(1983) 151 CLR 422 ... [omitting other footnotes] ... It would be unjust in the mind of the other when unaware of that person's state of mind. This injustice does not exist where the other party knew or should have known of the other's actual state of mind."
102For the Society's "mistake" argument to be made good, it must be shown that Mr Butterworth was aware of that mistake or misapprehension, or adopted a position of "wilful ignorance": Taylor v Johnson [1983] HCA 5; (1983) 151 CLR 422 per Mason ACJ, Murphy and Deane JJ, at [14]. There was no evidence that this was so.
103Having regard to that statement of principle, on the evidence before the CTTT, it cannot be reasonably said that Mr Butterworth either knew or ought to have known that at the time the parties entered into their agreement, the Society intended that their relationship should be governed by the provisions of the RT Act, and not, the provisions of the RV Act.
104Furthermore, in cases where a party asserts that the ultimate terms of a contract differ from the terms which the parties had commonly intended, establishing such an assertion is a heavy burden that is not lightly discharged. The evidence discharging that onus must be in the clearest and satisfactory manner, especially where the party asserting the existence of a mistake drew up the agreement. This is because, to rectify the mistake effectively, means rewriting the agreement of the parties to change their rights and obligations: Australian Gypsum Ltd v Hume Steel Ltd [1930] HCA 38; (1930) 45 CLR 54, at p 64. Written documents are not to be varied or re-written on the basis of slight presumptions: Moses v Northern Assurance Co (1856) 1 VLT 114, at p 115.
105The third such error, which involved a mixed question of fact and law, was that the CTTT Member did not recognise the importance of the conceded limitation within Mr Noonan's evidence to the effect that he was not authorised to amend the Village residential agreement contracts. Accordingly, Mr Noonan's evidence was a flimsy and unsound basis upon which to seek to re-write the rights and obligations of the parties under the agreement that they had signed, especially where he lacked the authority to make the assertion relied upon to establish the alleged "mistake". The consequential error was that Mr Noonan's evidence was then incorrectly used to base the finding at [34] of the CTTT reasons, that there had been a mistake made by the Society in attempting to implement s 5(3)(h) of the RV Act.
106The terms of s 5(3)(h) of the RV Act provide an exclusionary definition to the effect that a retirement village does not include any residential premises the subject of a residential tenancy agreement in the form prescribed under the RT Act where the operator of the premises is a party and the agreement contains a term to the effect that the RT Act does not apply to the residential premises that are the subject of the agreement.
107The agreement that the parties signed was just such an agreement. No suggestion of mistake arises from the face or the content of the agreement itself.
108The asserted mistake was raised in submissions to the CTTT by the defendant's solicitor: Transcript Day 2, page 72.22. That submission was not based on evidence that was reasonably probative of the claim of mistake, and should have been disregarded given the unambiguous terms of the agreement between the parties.
109The fourth such error involved the construction of s 5(1)(a) of the RV Act, which relevantly provides that if the premises are either predominantly or exclusively occupied or intended to be so occupied, by retired persons who have entered into village contracts with the operator of the complex, then the premises are a retirement village.
110That provision is an undemanding stand alone definition that is capable of being considered on its own to be used as a test to determine whether the Village was a retirement village within the meaning of that statutory definition. At paragraph [42] of the CTTT reasons the CTTT Member stated that she was "in no doubt" that the matters required by the cited s 5(1)(a) RV Act definition had been fulfilled.
111If a finding was required to the effect that the Village was a retirement village within the meaning of the statutory provision, according to the terms of s 5(1)(a) of the RV Act, given the CTTT finding at [42], this was sufficient for the conclusion to be reached that the complex in question was a retirement village.
112In those circumstances, it was then unnecessary for the CTTT to instead entertain notions of whether the matters identified at paragraph [109] above were sufficient to attract the operation of the RV Act, or to find, as the CTTT Member stated, that the otherwise accepted evidence was insufficient for that conclusion.
113The construction by the CTTT of s 5(1)(a) of the RV Act also involved an additional error because the real question was not whether the complex attracted the operation of the RV Act, as stated at paragraph [42] of the CTTT reasons.
114Instead, ultimately, as earlier identified, the real question was whether the parties intended to agree, as their agreement effectively stated, that the RT Act, should not govern their legal relations, thus bringing the RV Act into play, which is an entirely different matter.
115An evaluation of the agreement on its face demanded an affirmative answer to the preceding question according to the objective theory of contract. On that approach, a further error resides in paragraph [43] of the CTTT reasons in that, contrary to the conclusion there stated, beyond tendering the agreement and identifying its unaltered form and content, Mr Butterworth carried no further burden of proving that he had entered into an agreement with the Society that attracted the operation of the RV Act.
116The only matter Mr Butterworth had to show in order for him to succeed in the CTTT proceedings, was that he had an agreement with the Society that was on its face, unambiguous in its original terms. In my view he discharged that burden at the CTTT hearing. The findings against him to the contrary involved errors with respect to matters of law within the meaning of s 67(1) of the CTTT Act.
117It is clear from the Reasons for Decision of the CTTT, that in construing the agreement in question, the CTTT Member had regard to considerations that went beyond the terms of the agreement, and sought to determine an entirely separate and irrelevant matter that did not call for decision. That matter was the question of whether the Village in question was a retirement village within the meaning of s 5 of the RV Act.
118In my view, in the CTTT, a fundamental distinction arose to be recognised. This was the distinction between an analysis which examines the question of whether or not a village is in fact a retirement village to which the Act applies, and the quite separate analysis of a contract in which the parties have agreed that their binding mutual rights and obligations would incorporate the provisions of the RV Act by excluding the provisions of the RT Act.
119In my view the CTTT Member incorrectly focussed on the former proposition instead of the latter, and in doing so, made an erroneous decision on a question with respect to a matter of law.
