‘If the purchaser break the contract as, amongst other things, by failure to pay the price before the vendor has parted with his estate in the land, the vendor cannot recover the whole price as damages, but is limited to the loss which he has actually sustained, that is to say, the difference, if any, between the price agreed to be paid and the value of the land as remaining on his hands at the date of the breach.’
‘I can only add to that what is clearly the law, that he would be entitled to recover any further incidental expenses to which he had been put by being compelled to retain the land in his own possession instead of conveying it to the purchaser.’
‘The general rule does not require the court to close its eyes to matters occurring after the breach of the contract or after the commencement of the action or even after a judgment has declared the defendant’s liability without quantifying it, if they would enable the court to fix the plaintiff’s actual loss more accurately.’
‘[34] I agree that the availability of a market is a most relevant factor in relation to the date for assessment of damages for breach of a contract for the sale of land where the buyer fails or refuses to complete the purchase. It is hardly ever the case that there is a readily and immediately available market for the sale or purchase of land, in the sense that the seller can go out into the market on the date of breach, or the next day, and find a purchaser who can and will proceed to contract at once. … The definition of market value itself, to which I have referred above, involves an assumption that the property has been exposed to the market for a reasonable time, which is likely to be for more than a month and may well be several months or longer. If the comparison sought to be made is between the contract price and the market value as at the breach date, then the assessment of that market value, by an expert valuer on established principles, would have to assume a prior period of marketing, which, by definition, will not and could not have happened. … [38] It seems to me that the breach date is the right date for assessment of damages only where there is an immediately available market for the sale of the relevant asset or, in the converse case, for the purchase of an equivalent asset. This is most unlikely to be the case where the asset in question is land. If the defaulting party is the buyer, much will depend on what the seller does in response to the breach, as is suggested in Chitty on Contracts, 31st ed, para 26-014, cited above. If he resells, the buyer may be able to show that, in so doing, the seller failed to take reasonable steps to mitigate his loss, for example by taking too long, or failing to follow proper professional advice, or in some other way. Absent any feature of that kind, the eventual resale price is likely to be the figure to be set against the contract price for assessment of the damages, not because it represents the market value at the date of the breach, but because it shows what loss the seller has suffered, uncomplicated by issues of remoteness or failure to mitigate. If the property market has declined during that time, it is of no avail for the defaulting buyer to say that this should not be laid at his door. If he had completed the contract, he would have suffered that decline in value, so this is part of the loss for which the seller needs to be compensated.’
‘The significance of the price obtained in the open market as potentially the best evidence of open market value does not need to be demonstrated by expert evidence. It is obvious as a matter of common sense. Where a valuer is instructed to advise a bank as to the value of a property the sale of which has just been agreed, the marketing history of the property provides, potentially, evidence of the view that the market actually took of the value of the property. Plainly, the valuer should explore as carefully as he is able the marketing history of the property. The valuer will be aware of the limitations of the exercise of considering comparables as a guide to the price a property will actually achieve in the market. If the marketing history of the property is such as to leave the valuer confident that the property was properly marketed his consideration of the comparables will, essentially, be a cross-check of the validity of the sale price as evidence of value.’
‘[38] The standard of “reasonableness” is, however, applied with some tenderness towards the claimant having regard to the fact that the claimant's predicament has been caused by the defendant's wrongdoing: see Banco de Portugal v Waterlow & Sons Ltd[1932] AC 452 , 506; Britvic Soft Drinks Ltd v Messer UK Ltd [2002] 1 Ll Rep 20, para 114 (affirmed [2002] 2 Ll Rep 368, CA). Thus, the claimant is not expected to take steps which would involve unreasonable expense, risk or inconvenience: see Chitty on Contracts (31st edn, 2012), vol I, para 26-080. In addition, the burden of proof is on the defendant to show that there was a course of action which it was reasonable to expect the claimant to adopt that would have avoided all or an identifiable part of the claimant's loss: see e.g. Roper v Johnson (1873) LR 8 CP 167; Standard Chartered Bank v Pakistan National Shipping Corp [2001] CLC 825 at para 38. Furthermore, there is often a range of responses available to the claimant which will be regarded as reasonable. As stated by Potter LJ in Wilding v British Telecommunications plc[2002] EWCA Civ 349 ;[2002] ICR 1079 at para 55: “If there is more than one reasonable response open to the wronged party, the wrongdoer has no right to determine his choice. It is where, and only where, the wrongdoer can show affirmatively that the other party has acted unreasonably in relation to his duty to mitigate that the defence will succeed.”’
‘It should be unusual for a finding of a failure to mitigate to apply to a vendor who accepts the best available offer shortly after a purchaser’s failure to complete particularly where the vendor is carrying substantial bridging finance and is anxious to sell.’
‘Following our conversation I can confirm that we were approached to find a buyer for High Trees around October/November 2023 and that turned in to a formal instruction January 8th 2024 (see attached the signed terms). We did have soft interest around the£10m mark but our client wasn’t interested at those levels as she had bought the house at the height of the market significantly higher. We understand the price was around£16,000,000 . We were informed by our client that they did not wish to complete on the purchase of High Trees as they had decided to buy a house in Notting Hill instead, near her son’s school. We understand that she ended up purchasing a house on Hereford Road.’
