23 On the other hand, the contended term is quite a different matter altogether. It imposes a positive obligation not to do anything which might result in the lapse or early termination of the Z policies in order to relieve itself from the obligation under the agency agreement to pay commission. Such a term immediately raises the question of whether it means "solely" in order to avoid the obligation to pay commission; "substantially" or "partly" in order to do so, and so forth. As the learned trial judge observed in passing, saving of the commission was clearly in the mind of the respondent's Tasmanian manager - his memoranda make that clear. However, the cross-examination of this witness about the need to reduce losses by avoiding the payment of commissions on premiums paid in the third, fourth and fifth years was put in the context of an alternatively pleaded cause of action, based upon breach of fiduciary duty. This is apparent from the context and the closing submissions of senior counsel for the appellant at trial. Further, as mentioned, the respondent's Tasmanian manager did not have the necessary authority to make the critical decisions with respect to the Z policies. At the relevant time, the now managing director of the respondent, Mr Killen, was responsible for the business plans policies, one of which was the Z policy. He assumed this responsibility in May 1990 and gave evidence that he probably first became aware of the "problem" with the Z policies shortly after May 1990. Mr Killen said, without any detail, that his objective with respect to the Z policies was "to mitigate the loss that was then in prospect primarily, consistent with the circumstances retaining the goodwill of our clients and agents."
