[3] Mr Morris QC, appearing for the respondent, readily conceded that the respondent had not asked on the hearing of the appeal for orders for payment of that land tax paid, whereas it could have; and that no application was made then to place evidence of that payment before this court. Nor had any claim against the appellant plaintiff in respect of that land tax so paid been sought to be raised by way of any amended ground of appeal by the respondent. Nevertheless, Mr Morris QC submitted, the mortgaged debt which would be assigned to Marminta by the order for specific performance made 5 December 2003 would be a debt increased by the amount of that land tax, (and of the claimed rates), and the plaintiff would have assigned to it rights as creditor in respect of that larger sum owing, and when the land against which that sum was secured was correspondingly cleared of those same liabilities. The submission made was that since this court was the first to order specific performance the court was obliged to fashion orders which were equitable, and that was all the respondent was asking. To do otherwise would give the appellant a windfall benefit, and more that it had contracted to obtain for $950,000.00; and it would be unjustly enriched at the respondent's expense.
