The present case, in relation to the variation, was not capable of falling within the second category and accordingly must either have fallen within the first class (parties intending to be immediately bound) or within the third class (no concluded bargain until formal wording prepared).
16 The Appellant argued that the variation fell within the third class, because there was a well-established "sign-off process" within AMP Life Limited. Various witnesses, it was submitted, had attested to or accepted that fact. Although it was clear that the process had been followed in relation to the brochure, the brochure itself stated that it was subject to the terms of the policy. Accordingly, AMP Life Limited itself gave separate and predominant effect to the policy. Because it was not in dispute that the formal variation of the policy had not been effected until April 2004, it must have been the case, so it was argued, that the variation had no effect, despite the terms of the brochure, until the memorandum of alteration to the plan was executed on 5 August 2004.
17 The primary judge found that a binding and effective agreement was reached between the AMP Life Limited and the Trustees at least by the time that Mr Campbell, on behalf of AMP Life Limited, executed the "sign off certificate" for the brochure, on 23 November 1999. Whilst his Honour was conscious of the fact that no similar certificate was then executed in relation to the policy, as might have been expected, his Honour noted that there were significant and weighty factors which favoured an objective assessment of intention to be bound by the policy document subject to the variation. For example, his Honour noted that AMP Life Limited could not lawfully issue a policy unless an actuary had given written advice about the terms and conditions under which the policy was issued, pursuant to s 116 of the Life Insurance Act 1995 (Cth): at [56]. That advice was provided on 30 December 1999. Secondly, his Honour noted that the premium rates were those which Swiss Re had approved on the basis that the amendments it wanted had been made: at [58]. Thirdly, his Honour noted that, although there was on-going discussion between the Trustees and AMP Life Limited during the year 2000, without agreement being reached, those discussions did not support the Appellant's argument, but rather the contrary. His Honour stated at [99]:
"Those discussions do not detract from there having been an agreement, which was put into effect from 1 January 2000, concerning introduction of the mental illness limitation. Rather, what they show is that the trustees continued to be dissatisfied with the agreement that they had reached, and were seeking, unsuccessfully, to change it."
18 In short, both AMP Life Limited and the Trustees of the plan continued to issue policies and administer the trust, respectively, on the basis that the relevant variation had been made. The evidence of each of Mr Campbell (for AMP Life Limited) and Messrs McLean, Kelly and Patterson (being the Second-Fourth Respondents and the Trustees of the plan) affirmed that the document executed in August 2004 conformed to the changes agreed in November 1999. Each of them stated in their affidavits that "the memorandum reflected the amendments to the Plan that I had agreed upon during November 1999" or words to that effect: none of them was shaken in cross-examination. The memorandum executed in August 2004 itself stated that "the policy is amended with effect from 1 January 2000" by the amendments thereafter set out. The language set out in that memorandum was not identical with that found in the brochure, but its effect is the same.
19 In these circumstances, his Honour concluded that the objectively determined intent of the parties was that the relevant variation take effect from 1 January 2000 and that the policy was so varied. No error has been shown in his Honour's reasoning or conclusion.
20 By way of cross-claim, the Respondents sought an order of rectification to give effect to their common subjective intention, being the intention of the respective parties to the policy, that the document be so varied. His Honour stated at [180]:
"I conclude that the trustees, and AMP, each had a subjective intention that the amendment to the Plan concerning the limitation on mental illness benefits would take effect from 1 January 2000. They also had a subjective intention that that amendment would be given effect to by an appropriate written amendment to the policy document being made. It was not the subjective intention of any of them, however, that no such amendment to the terms on which insurance was offered under the Plan would be effective until such a document had been executed. These conclusions do not lead, however, to a conclusion that the policy document should be rectified. This is because, following the making of the agreement to vary the Policy, it was not the intention of the parties that their contract was one which was one expressed in writing, so far as that variation is concerned. They intended that their contract would become one expressed in writing, but that is not the same thing."
