[A] The main claim. The contract required him to pay no more than $2,250,000.00 so he is entitled to recover the extra $225,000.00 as money had and received. That is because Special Condition 7
(i) on its proper construction, had no application in the circumstances of the sale, or
(ii) on its proper construction, meant that the purchase price stipulated in the contract was GST-inclusive, or
(iii) was so uncertain as to be meaningless.
[B] Alternative claims are made on the footing that the Tribunal finds, contrary to Mr Booth's contentions, that on its proper construction Special Condition 7 meant that the purchase price was GST-exclusive and so totalled $2,475,000.00.
(I) Rectification. The contract ought to be rectified, to reflect an intention that the purchase price was $2,250,000.00 and no more.
(II) Excision. If rectification of the contract is not available, the Tribunal should, as a consequence of Cityrose's misleading or deceptive conduct in contravention of the Fair Trading Act 1999, exercise its powers under that Act to vary the contract by excising Special Condition 7 from it.
(III) The consequence of (I) or (II) would be the right to recover $225,000.00 either as money had and received or because the power under the Fair Trading Act to order a refund of that sum should be exercised.
(IV) Damages. Alternatively, if Special Condition 7 is not rectified or excised, Mr Booth has suffered loss and damage because of the misleading or deceptive conduct of Cityrose or of Kay & Burton or of both of them. By offering the land for sale in the way that they did, and by producing to him the contract of sale in the way that they did and in the terms that it took, they induced him to enter into the contract in the belief that it obliged him to pay $2,250,000.00 and no more. In truth it obliged him to pay $2,475,000.00. He thereby lost $225,000.00 plus additional stamp duty of $12,375.00. Either or both of the respondents are liable to pay those sums.[3]
