(d) The deficiency on resale
63 The difference between the sale price of $3,800,000 and the resale price of $3,350,000 is $450,000.
64 In calculating the deficiency on resale, the relevant authorities establish that the original sale price (against which the resale price must be deducted) comprises both the original contract price and any special condition interest recoverable: Zografakis (supra) at [21]; Carpenter (supra) BC9604107 at 12 (per Clarke JA). As explained by Hamilton J in Zografakis, had the contract been completed on the date on which it was in fact terminated, the plaintiffs would have received the balance of the purchase price as well as the special condition interest. Accordingly, the special condition interest forms part of the original sale price used to calculate the deficiency.
65 The question remains, however, as to whether, in calculating the deficiency on resale, the net sale and resale prices of the property are employed (after taking into account the agent's commission) or whether the gross sale and resale prices are employed.
66 Mr Thompson outlined the alternative possible ways of calculating the deficiency depending upon whether or not agent's commission is brought into account in both the sale and resale prices or not. He stated in that regard:-
"20. There appear to be two logical ways of computing the deficiency on resale -
(i) The difference between the sale and resale prices without adjustment, here $418,493 less deposit of $50,000 - $368,493. That was the course adopted by: Rolfe J in CFA Group Services Pty Ltd v Mars Trading Pty Ltd (2001) BC200100717 at [98], [100], [121] and [164]: Hamilton J in Zografakis at [18]; and Fryberg J in Dovaenda Pty Ltd v Pagliari (2007) BC200706841 (unreported; SCQ, 22.8.2007) at [16] and [34]; but see White J in Buchanan v Dunstan at [65]
or
(ii) The difference between the sale price ($3,818,493) reduced by the commission which would have been payable ($62,700) being $3,755,793, and the resale price ($3,350,000) reduced by the commission paid ($55,275) being $3,294,7256, here $461,068, less the deposit of $50,000 - $401,068. However, White J in Buchanan v Dunstan at [64] saw that, having regard to the second limb of Cl. 9.3.1, that construction could not be adopted."
67 I note that, in relation to calculations in 20(i) above, there is an error of calculation. The figure of $368,493 is incorrect as the deposit of $50,000 was applied to derive the figure of $418,493. That latter figure represents the difference between the sale and resale prices having already taken into account the deposit.
68 In relation to calculation in 20(ii) above, the amount of $401,068 is incorrect and should read $411,068.
69 I accept as Mr Thompson contended, arithmetic errors notwithstanding, that the first of the two courses should be followed. On that basis, the deficiency on resale is the amount of $418,493.11.
