“I am clear, on the other hand, that the unjust enrichment claim against Mr and Mrs Costello must fail because it would undermine the contractual arrangements between the parties, that is to say, the contract between the claimants and Oakwood and the absence of any contract between the claimants and Mr and Mrs Costello. The general rule should be to uphold contractual arrangements by which parties have defined and allocated and, to that extent, restricted their mutual obligations, and in so doing, have similarly allocated and circumscribed the consequences of non-performance. That general rule reflects a sound legal policy which acknowledges the parties’ autonomy to configure the legal relations between them and provide certainty, and so limits disputes and litigation.”
“. . . the parties to the contract had no shared or even individual expectation as to how the risk of the sale price being less than£6.5 million should be allocated for the purpose of determining whether Mr Barton should be entitled to payment. The Court must therefore consider whether to impose an obligation on Foxpace to make payment in circumstances which were not contemplated when the contract was concluded.”
“190. In favour of the argument that Mr Barton should be treated as assuming the risk of not being paid for the introduction, it seems to me that the only substantial argument is that the parties failed within the contract to define an obligation on Foxpace to pay the fee in the circumstances of the sale of Nash House for a figure of less than£6.5 million when they could have done so. The principle set out in MacDonald v Costello should therefore be applied, namely that the parties' mutual obligations in a case in which they concluded a contract should be limited to those which they have defined and allocated in the course of negotiating that contract, so as to give effect to the need for the court to uphold contractual arrangements. 191. In my judgment, there is a strong argument for the court declining to interfere with the agreement by which the parties have determined the circumstance in which a sum of money will be payable by granting relief which amounts to an imposing an obligation to pay in different circumstances. Granting such relief amounts to an obvious interference with the freedom of parties to define and allocate their obligations. In circumstances such as those of the instant case, it is in my judgment incumbent on the Appellant to show why the court should in effect interfere with the allocation of risk by imposing an obligation on the Respondent to pay money in circumstances other than those contemplated by and defined in the contract.”
“ . . nothing in those two letters could reasonably be interpreted, as it seems to me, as saying: “and if these prices are not realised, but I introduce a purchaser to you who does in fact buy at a lower price, then I agree to take nothing, and you are not to be under any obligation to pay me”
“But suppose that the Plaintiff, as an estate agent, introduced somebody as a purchaser to the Defendants and the Defendants accepted the introduction and did sell to such a purchaser but at less than£35,000 , then it could not be that the Plaintiff was not to be remunerated at all. That would be most unreasonable, and that could not have been in the contemplation of these parties. If you invite somebody to render a service, in circumstances in which payment is usual, and the service is rendered and accepted and a specific charge has not been agreed upon, then a reasonable sum becomes payable for the service. ... The contract did not set out what was the amount to be paid if a purchaser at less than£35,000 was introduced as a result of which there was a sale, but the contract certainly did not provide that there was to be no remuneration in the case of the introduction of a purchaser to whom the company decided to sell for less than£35,000 .”
“The agent is promised a reward in return for an event, and the event has not happened. He runs the risk of disappointment, but if he is not willing to run the risk he should introduce into the express terms of the contract the clause which protects him.”
“No obligation is imposed on the agent to do anything. The contracts are merely promises binding on the principal to pay a sum of money upon the happening of a specified event, which involves the rendering of some service by the agent. . . . The agent is promised a commission if he introduces a purchaser at a specified or minimum price. The owner is desirous of selling. The chances are largely in favour of the deal going through, if a purchaser is introduced. The agent takes the risk in the hope of a substantial remuneration for comparatively small exertion. . . . There is no lack of business efficacy in such a contract even though the principal is free to refuse to sell to the agent’s client.”
“. . . In that regard, the fact that Mr Sawiris offered€75.1m for services which would ordinarily be valued at€36.3m plainly calls for an explanation. Was there something exceptional about the circumstances which rendered Mr Benedetti’s services exceptionally valuable? The judge did not identify anything about the circumstances in which the services were provided which would indicate that they had a higher objective value in those circumstances than their ordinary market value. Or was Mr Sawiris's offer influenced by extraneous factors, such as the desire to settle Mr Benedetti’s claim in the shadow of potential litigation? If so, the offer would not be reliable evidence of the objective value of the services at the time they were received. Or was Mr Sawiris simply being generous, as Mr Abdou said in the relevant emails, and as Mr Sawiris maintained in his witness statement? If so, the offer would again not be reliable evidence of the objective value of the services: generosity (or parsimony) may influence a person's attitude towards paying a given price, but it does not affect the objective value of what he has received. Or was Mr Sawiris influenced by the success of the venture in connection with which Mr Benedetti’s services had been provided? If so, the offer would again not be reliable evidence of the objective value of the services, since that value has to be determined as at the time when the services are received, and cannot be quantified with hindsight in the light of their success.”

“what the parties did here was merely to define the terms upon which the commission was to be quantified and fixed at particular amounts. That did not exclude the payment of reasonable remuneration for services rendered and accepted by the defendant.”
