What was the agreement reached between Mr Leviston and PQ Management as to completion?
55 Whatever was the agreement reached between the parties, it was not reduced to writing. Neither was it confirmed in the course of any emails or other correspondence. That is, perhaps, emblematic of the casual manner in which the parties conducted their dealings. The result is that the identification of what the agreement was is undertaken by an analysis of the direct evidence of Mr Ison and Mr Leviston and of the surrounding circumstances, in particular, those which might be consistent with either version.
56 In the course of submissions both parties made some reference to the question of the extent to which the post-contractual conduct of the parties might be relied upon by the Court although no clear analysis was ultimately provided. Moreover, each party referred to post-contractual events in an attempt to strengthen their asserted version of the agreement.
57 It must be kept steadily in mind that the agreement in question is the oral variation of a written agreement and, there being no dispute as to the existence of such an agreement, the issue was only as to its terms. For the reasons discussed below it is not technically necessary to determine the extent to which the Court might rely upon post-contractual conduct in the current circumstances. That is because the evidence of Mr Ison as to the entry into of the agreement is preferred to that of Mr Leviston. However, were it necessary to decide, the preferable view would appear to be that expressed by Edelman J in Hightime Investments Pty Ltd v Adamus Resources Ltd [2012] WASC 295 [98]-[99] where his Honour said:
[98] This subsequent conduct is a relevant matter to consider in finding whether, as a fact, the alleged oral promises were made. Mears v Safecar Security Ltd, Stephenson LJ (with whom O'Connor LJ and Sir Stanley Rees agreed) said:
I have already expressed my view that this agreement was oral, but even if it was partly in writing, we are concerned with the search for a term that was not written down, and there is nothing in those authorities which prevents the court from looking at the way the parties acted for the purpose of ascertaining what that term was. Common sense suggests that their subsequent conduct is the best evidence of what they had agreed orally but not reduced to writing, though it is not evidence of what any written terms mean.
[99] This passage was approved by Owen J in The Bell Group Ltd (in liq) v Westpac Banking Corporation (No 9) and the latter half was quoted with approval by Murphy JA (Pullin & Newnes JJA agreeing) in Fazio v Fazio. The statement by Stephenson LJ is consistent with statements in a number of other cases. Spigelman CJ has also described post-contractual conduct as a matter of "significant weight" in identifying the subject matter of an alleged oral contract. This approach also accords with principle. It would be peculiar if courts were to be constrained in the exercise of finding facts from considering any relevant matter subsequent to the alleged occurrence of the fact in issue.
58 In his affidavit of 12 November 2021, Mr Ison gave evidence as to how he alleged the agreement varying the method of calculating the purchase price came about. He claimed that he commenced working in the TWA business from 3 July 2017 as if completion had taken place. He said that his immediate focus was on finalising the figures for the purposes of completion of the sale and, in the course of that, he prepared multiple spreadsheets evidencing the company's finances which he provided to Mr Leviston. He claimed that he had numerous discussions with Mr Leviston about them and their content including the manner in which Mr Leviston's loan account with the company could be dealt with at settlement. In the course of cross-examination Mr Ison denied that he was preparing TWA's financial figures for the purposes of ascertaining its position as at 1 August 2017, and that all he was doing was attempting to understand the position as at 30 June 2017 (ts 55). Mr Ison should be accepted on this issue and there was no evidence to the contrary.
59 Mr Ison further deposed that in early July 2017, being shortly after the third of that month, he said that he and Mr Leviston agreed that as the financial data for TWA for the financial year ending 30 June 2017 had almost been completed, those figures would be used at completion for the purposes of calculating the purchase price and that PQ Management (or Mr Ison and Mr Eldridge) would pay interest on the amount so calculated to the date of settlement. Mr Ison gave further evidence to the effect that a rate of 9% was subsequently agreed and, as calculated, equated to $6,758.78, being for a period of 31 days from 3 July to 3 August 2017. He denied that the agreement to pay that interest arose because the completion date which had originally been mooted under the MOU, being 1 July 2017, had been pushed back to 1 August. Again, his evidence on this topic is supported by the commercial logic of the circumstances. As the Share Sale Agreement specified 1 August 2017 as the date for completion, there no basis on which it might be thought that any legal or moral obligation to pay interest might have arisen. Certainly, none was suggested.
60 For the purposes of settlement Mr Ison prepared draft settlement statements which he provided to Mr Leviston and Mr Leviston's solicitors. Mr Leviston acknowledged that his solicitors received by an email of 2 August 2017, from Mr Ison's solicitors, a working draft of the settlement statement with attached notes (CB 250). The email, which had the heading of, "Plumbers Qld draft settlement numbers", was also sent to Mr Leviston and his business broker, Mr Brendan Forde. The attached document is headed, "Settlement Working", and shows a draft of the figures which would be later incorporated into the settlement statement. It also shows some breakdown of the draft figures. On the second page is the heading "Post 30/6/2017 adjustments". Thereafter, three entries appear as "Bank", "Wages" and "TL Credit Card". The initials "TL" is a reference to Troy Leviston. Amounts appear adjacent to those entries which are shown to total $50,494.65. A further note states "TL expenses from 3/7 to cob 27/7 reimbursement to TWA". In the context of Mr Ison's evidence these are the workings and conclusions as to the amount which, on his version of the settlement agreement, were to be paid by Mr Leviston to TWA. Mr Leviston said very little about this document other than acknowledging that it was received by his solicitors. Its import is that it demonstrates that Mr Ison was acting consistently with what he said was the settlement agreement; namely that the parties would operate as if settlement had occurred on 1 July 2017 by a payment calculated as of that day. On that basis, Mr Leviston's personal expenses which were paid for by TWA in the month of July 2017 would need to be reimbursed on the date of actual completion. If no agreement as Mr Ison alleges was struck, there is no explanation for him calculating Mr Leviston's personal expenses incurred in July 2017 and identifying them as an amount which Mr Leviston was required to pay to TWA on settlement. When that context is understood, it is clear from the email of 2 August 2017 that Mr Ison was asserting that Mr Leviston's expenses incurred by TWA in the month of July were to be reimbursed on settlement. There was no attempt to disguise or conceal this and it is conduct consistent with the settlement agreement which Mr Ison alleges.
61 Later on 2 August 2017, PQ Management's solicitors emailed to Mr Leviston's solicitors a draft of the formal settlement statement for use at completion. It indicated that the time and place of settlement was to be confirmed, but identified that the settlement date and the adjustment date were both 3 August 2017. The figures set out in it were in accordance with the draft statement and workings which had been sent that same day, and they indicated both the interest payment by PQ Management and that a payment of $50,494.65 would be made at Mr Leviston's direction to TWA from the purchase price. Mr Leviston's solicitors utilised this document to prepare a formal settlement statement for the purposes of effecting completion, which they emailed to PQ Management's solicitors on 3 August 2017, describing it as the "Final Settlement Statement". That version identified that both the "settlement date" and the "adjustment date" were 1 August 2017. Otherwise, apart from inserting the time and place for settlement, it reflected the draft sent by PQ Management's solicitors.
62 To a large extent this correspondence supports Mr Ison's version of the settlement agreement. It proceeds upon the working figures sent to Mr Leviston and his solicitors which showed that interest was being paid on the purchase price from 1 July 2017 and that the amount of $50,494.65 was to be paid by Mr Leviston to TWA on completion in respect of the expenses incurred by him in July 2017. It is appropriate to consider the relevance of these two matters in more detail.
