41 In substance, this involves a claim for damages for late payment of such instalments of the debt of $529,150 as Mrs Fiala, using best endeavours, could have paid; such damages are in the nature of interest, from the date on which she could have paid the instalments. Where there is a wrongfully caused loss of use of money (which includes such a loss caused by tort or by breach of contract), damages assessed wholly or partly by reference to the interest which would have been earned or saved had the money been available to the payee are recoverable [Hungerfords v Walker (1989) 171 CLR 125, 143-4 (Mason CJ and Wilson J), 152 (Brennan and Deane JJ)]. The liability for damages in the nature of interest for late payment of a debt is independent of any contractual obligation to pay interest [Cook v Fowler (1874) LR 7 QB 27].
42 The Fiala Estate contends:-
· That upon the proper construction of the December 1994 agreement, no breach is established; alternatively
· That any entitlement to or claim for interest has been waived by Hexiva; and alternatively
· That Hexiva has failed to mitigate its damages.
43 Construction. By clauses 8, 9 and 10 of the Minutes of the December 1994 meeting, the parties agreed that Hexiva would accept $529,150, in full settlement of any claim Hexiva might have, Hexiva forgiving $100,000 "interest", and that Mrs Fiala would
… use her best endeavours to pay the sum of $529,150, free of interest, to Hexiva Pty Limited in full settlement of any claim Hexiva Pty Limited may have. She would do so in such instalments as she may afford by using her share in the profits of the Lederer/Fiala partnership and the 822 George Street Partnership as and when she may receive same, remaining after payment of her taxes and keeping about $50,000 per year for her own purposes.
44 In construing these provisions, one must consider the whole instrument, and if possible construe the words of every clause harmoniously with each other [Australian Broadcasting Commission v Australasian Performing Right Association Ltd (1973) 129 CLR 99, 109].
45 While an obligation to use "best endeavours" does not require the person who undertakes it to go beyond the bounds of reason, he or she is required to do all that can reasonably be done in the circumstances to achieve the contractual object (but no more) [Sheffield District Railway Co v Great Central Railway Co (1911) 27 TLR 451, 452; Terrell v Mabie Todd & Co Ltd (1952) 69 RPC 234, 237; Transfield Pty Ltd v Arlo Engineering Ltd (1980) 144 CLR 83, 101 (Mason J), 107 (Wilson J); Hospital Products Limited v United States Surgical Corporation (1985) 156 CLR 41, 64 (Gibbs CJ)]. As Mason J (as he then was) said in Transfield (at 101), such an obligation describes a standard of endeavour that is measured by what is reasonable in the circumstances. The content of a "best endeavours" clause is influenced by its contractual and factual contexts [Hospital Products, 64].
46 Relevant context for the construction of the clause in question here is provided by the following circumstances:-
· The parties intended their agreement to settle and compromise the outstanding dispute, and cannot have intended that payment be discretionary.
· The December 1994 agreement did not fix any time for payment, other than by reference to receipt by Mrs Fiala of distributions of profit from the partnerships.
· The "best endeavours" clause was not left unexplained; clause 9 proceeded to describe what "best endeavours" required, namely to pay the debt "in such instalments as she may afford by using her share in the profits of the [two partnerships] as and when she may receive same, remaining after payment of her taxes and keeping about $50,000 per year for her own purposes.
· The matrix of facts known to the parties included that there was an existing practice of distributing to Mrs Fiala $4,000 per month, which Mrs Fiala apparently used for her living expenses (approximately equivalent to the $50,000 per year which the agreement provided she could retain for her own purposes); and that payments of her income tax were also made from her profit share from the partnerships on her account; these tax payments can be identified in the accounts as drawings of amounts in other than round figures.
47 Mr Hallen SC, who with Mr C.F. Hodgson appeared for the Fiala Estate, submitted that - in the context that, to the knowledge of all parties, Mrs Fiala had additional commitments, other than in respect of living expenses, taxation and the partnerships, and was in the habit of making generous gifts to both her daughters that would in the future continue (at least to Mrs du Maurier) - the proper construction of clause 9 is that Mrs Fiala was obliged to use her best endeavours to repay the debt, from her share in the profits of the partnerships as and when she received them, but allowing her the opportunity to do so in such instalments as she could afford, bearing in mind her other financial obligations then in contemplation of the parties, including gifts to her daughters or either of them, and other commitments that were unrelated to the two partnerships, to her tax and/or to living expenses.
48 Such a construction - effectively inserting the words italicised on the preceding paragraph - involves reading into clause 9 words which give it practically opposite effect to those which it in fact contains: whereas the words of the clause provide for payments "in such instalments as she may afford by using her share in the profits of the [two partnerships] as and when she may receive same, remaining after payment of her taxes and keeping about $50,000 per year for her own purposes", the suggested construction would include in the "affordability equation" other outgoings not referred to in the clause, including voluntary payments to Mrs du Maurier. Yet it was contended that the availability to Mrs Fiala of income or assets from sources other than the profits of the two partnerships was irrelevant to the "affordability equation", because her share in those profits was the only source identified in clause 9. If that were the intended effect of clause 9, then there was no reason to limit, to tax and $50,000 per year, what Mrs Fiala could retain for her own purposes; and nothing was achieved by doing so: such a construction would effectively render Mrs Fiala's obligation to pay discretionary, by postponing it to voluntary payments to Mrs du Maurier and such other expenses as she might choose to prefer. By excluding additional resources from, yet including additional commitments in, the affordability equation, and permitting voluntary payments to Mrs du Maurier in priority to payment of the debt, it would operate so unfairly against the Plaintiffs' interests that it is not reasonable to regard the parties as having intended it.
49 In my judgment, clause 9 obliged Mrs Fiala to pay the debt, free of interest, by instalments constituted by what was left available to her from each distribution to her of her share in the profits of the two partnerships, as and when she received such distribution, after provision for payment of her taxes and about $50,000 per year for her own purposes. The strongest argument against this construction is that it converts a "best endeavours" obligation into an absolute one, and gives no work to the word "affords". However, it is not in issue that there was an absolute obligation to pay the debt - indeed there could not have been a binding compromise if payment were discretionary; the question to which the "best endeavours" obligation was addressed was the timing of the payment. The parties agreed that immediate payment was not required, but that the debt would be paid as soon as possible, by such instalments as could be afforded, thus the "best endeavours" clause. They then defined what would constitute "best endeavours". The words "as and when she may receive same" provided the timing element for the instalments, referable to receipts from profit distributions from the partnerships, and the words "as she may afford" provided the quantifying element, specifying what could be taken into account in calculating affordability. Thus, for the purposes of the clause, Mrs Fiala could "afford" what was left after deduction of tax and about $50,000 per annum from her receipts from the partnership profit distributions.
50 It may well be correct, as Mr Hallen submitted, that such a result could have been achieved by simpler words, omitting "best endeavours" and "afford". However, the circumstance that the most felicitous drafting has not been employed is not a reason to deprive the words of the clause of the meaning that, in their contractual and factual context, they were objectively most likely intended to bear.
51 Breach. Did Mrs Fiala breach the December 1994 agreement, by failing to use her best endeavours to make repayments on that basis? Three matters combine to dictate an affirmative answer.
52 The first is Mr Winter's 7 March 1997 letter to Mrs Fiala. In summarising a discussion between them and Mrs du Maurier on 4 March 1997, he recorded that Mrs Fiala had told him that she had made no payment to date because she had not been asked to make any payment, though she had the means to make the payment if required, but preferred not to do so, leaving the debt to be paid out of her estate. There is no reason to question the reliability of Mr Winter's record. This establishes an admission by Mrs Fiala of a failure to use best endeavours. Even on the alternative construction of clause 9 for which the Fiala Estate contended, that would establish a breach.
53 The second is the circumstance that Mrs Fiala received at least three distributions from the Lederer-Fiala Partnership - $20,000 in or about March 1996, another $20,000 in or about August 1996, and $90,000 in or about November 1997, which she endorsed to Mrs du Maurier, rather than paying to Hexiva. That she was able to endorse such distributions to Mrs du Maurier is strong evidence that she could have "afforded" to pay them to Hexiva, but did not do so.
54 Thirdly, analysis of the distributions which Mrs Fiala received from the two partnerships over the period after December 1994 establishes that, after $48,000 per annum (drawn by her as $4,000 per month from the Lederer-Fiala Partnership), and after taxation payments, she received the following further distributions:-
· LFP 14/02/95 $30,000
· GSP 30/05/95 $35,000
· LFP 31/05/95 $50,000
· GSP 29/08/95 $30,000
· GSP 30/11/95 $35,000
· LFP 30/11/95 $25,000
· GSP 28/02/96 $35,000
· LFP 28/02/96 $20,000
· GSP 31/05/96 $35,000
· GSP 31/08/96 $32,000
· LFP 31/08/96 $20,000
· GSP 29/11/96 $38,000
· LFP 15/01/97 $5,000
· GSP 11/02/97 $25,000
· GSP 30/05/97 $30,000
· LFP 30/05/97 $5,000
· GSP 29/08/97 $30,000
· LFP 28/11/97 $90,000
55 The last of those distributions, when added to the preceding ones, exceed what was required to pay the Hexiva debt in full. I am therefore satisfied that Mrs Fiala, using her best endeavours to do so, could have afforded, by using her share in the profits of the partnerships as and when she received them, after payment of her taxes and keeping about $50,000 per year for her own purposes, to make payments to Hexiva under the December 1994 agreement, substantially as follows:
· LFP 14/02/95 $30,000
· GSP 30/05/95 $35,000
· LFP 31/05/95 $50,000
· GSP 29/08/95 $30,000
· GSP 30/11/95 $35,000
· LFP 30/11/95 $25,000
· GSP 28/02/96 $35,000
· LFP 28/02/96 $20,000
· GSP 31/05/96 $35,000
· GSP 31/08/96 $32,000
· LFP 31/08/96 $20,000
· GSP 29/11/96 $38,000
· LFP 15/01/97 $5,000
· GSP 11/02/97 $25,000
· GSP 30/05/97 $30,000
· LFP 30/05/97 $5,000
· GSP 29/08/97 $30,000
· LFP 28/11/97 $49,150
56 In fact, however, she paid only $29,150 on 1 April 1997, and $25,000 on 21 November 1997, and her estate $475,000 on 17 May 2001. Thus Mrs Fiala failed to use her best endeavours to pay the debt as required by the agreement, being in breach of her obligation to do so from as early as February 1995, and to the extent that by the time of her death, there was a breach in respect of the whole amount of the debt, because applying the relevant criteria of affordability under the December 1994 agreement, the whole debt could have been paid before her death. It is therefore unnecessary to consider whether her estate failed to use its best endeavours to pay the debt after her death, although I am inclined to the view that in the context of the contested probate litigation it committed no breach; but that does not avail it when Mrs Fiala had herself committed a breach in respect of the entire debt before her death.
57 Waiver. The Fiala Estate maintains that Hexiva has waived any entitlement to interest. Mr Sahade, who appeared at short notice for the Plaintiffs and presented a responsibly limited and confined case in place of the much more extensive one originally pleaded and foreshadowed by Dr Wechsler, rightly submitted that waiver had not been pleaded, but I permitted the Fiala Estate to pursue the issue, since it seemed clear enough on the evidence and pre-trial submissions that it would be raised in one guide or another, and I thought it could be addressed without undue prejudice to the Plaintiffs.
58 I accept the factual matters on which the Fiala Estate relied for submitting that Hexiva had waived any claim for interest. In particular, I accept that prior to December 1994 the Plaintiffs had indicated that they did not wish to cause Mrs Fiala hardship; that they did not press for payments from Mrs Fiala after 1994, and indeed decided to remain silent, notwithstanding suspicions that she was not using her best endeavours to pay, in order to keep the peace; that they did not raise the question of any breach of the best endeavours obligation, or any claim for interest, with her or anyone else on her behalf prior to her death; and that they did not prior to January 2001 make any demand for payment from her estate (save an oral request of the administrator pendente lite, who had no power to pay).
