“The law on implication of terms is found in AG of Belize v Belize Telecom [2009] 1 W.L.R. 1988. As Lord Hoffman said at paragraphs 16,19 and 21, the law is concerned to discover what the instrument means, what meaning the instrument would convey to a reasonable person having all the background knowledge which would be reasonably available to the audience to whom the instrument is addressed. The implication of a term is an exercise in the construction of the instrument as a whole; the question is whether a proposed [implied] provision would spell out in express terms what the instrument, read against the relevant background, would reasonably be understood to mean. The test of “it goes without saying” and “necessary to give business efficacy to the contract” are not different tests, but merely different means for reaching a conclusion as to what the contract should be reasonably understood to mean. There are, as he pointed out, dangers in taking those tests as if they had a life of their own.”
“Moreover, as I read Lord Hoffman’s analysis, although he is emphasising that the process of implication is part of the process of construction of the contract, he is not in any way resiling from the often stated proposition that it must be necessary to imply the proposed term. It is never sufficient that it should be reasonable. This point is clear, for example, from the well-known speech of Lord Wilberforce in Liverpool City Council v Irwin[1977] AC 239 , where he rejected at page 253H to 254A the approach of Lord Denning, which was to permit the implication of reasonable terms. He identified two classes of implied term in the case (as here) of a complete bilateral contract. He said that in a case of established usage the courts are spelling out what both parties know and would, if asked, unhesitatingly agree to be part of the bargain. That is not, in my opinion, this case. Lord Wilberforce added at page 253G: In other cases, where there is an apparently complete bargain, the courts are willing to add a term on the ground that without it, the contract will not work – this is the case, if not of The Moorcock…itself on its facts, at least of the doctrine of The Moorcock as usually applied.”
“A term can only be implied if it is necessary in the business sense to give efficacy to the contract; that is, if it is such a term that I can confidently be said that if at the time the contract was being negotiated some one had said to the parties, ‘What will happen in such a case’, they would both have replied, ‘Of course, so and so will happen; we did not trouble to say that; it is too clear’. Unless the court comes to some such conclusion as that, it ought not to imply a term which the parties have not themselves expressed…”
“The court will not even improve the contract which the parties have made for themselves, however desirable the improvement might be. The court’s function is to interpret and apply the contract which the parties have made for themselves. If the express terms are perfectly clear and free from ambiguity, there is no choice to be made between different possible meanings: the clear terms must be applied even if the court thinks some other terms would have been more suitable. An unexpressed term can be implied if and only if the court finds that the parties must have intended that term to form part of their contract: it is not enough for the court to find that such a term would have been adopted by the parties as reasonable men if it had been suggested to them: it must have been a term that went without saying, a term necessary to give business efficacy to the contract, a term which, though tacit, formed part of the contract which the parties made for themselves.”
“In this case, by contrast, there is, as I see it, no ambiguity whatever in the wording of clause 21(1) of conditions “C” and what the respondents are asking the court to do is, in effect, to rectify the clause by the addition of some words which will make it accord not indeed with the actual intention of the parties but with the intention which the respondents say must be imputed to them. In such a case, as I have always understood the law, it is not enough for the party seeking to have the words varied to say to the court, “We obviously did not mean what we have said, so please amend the clause so as to make it read in what you think is the most reasonable way.”
“Given the importance of communicating both internally and with any external advisors, reaching a properly informed decision, determining whether to terminate and /or commence arbitration and ensuring that notices are validly delivered, each member of the tribunal independently considered that the correct period was 7 days before expiry. The Sellers were given over 6 months to secure the extension and the Buyers were, in our view, entitled to be absolutely certain that the extended Refund Guarantee was in place 7 days before expiry. If the extension was not obtained by23rd June 2010 , the breach was in our view so serious as to go to the root of the Contract. We do not therefore consider that there was sufficient reasonable time to be certain that the breach would be remedied as to prevent the breach from going to the root of the contract. We have explained why specific performance cannot be granted by the Tribunal. In those circumstances, we do not consider that the temporary extension of the Refund Guarantee during the arbitration is sufficient to prevent the breach going to the root of the contract. There is no relief which the Tribunal can grant, which ensures that the Refund Guarantee is permanently extended to the agreed date. Therefore as from 23rd June the Sellers were in repudiatory breach of contract and the Buyers were entitled to terminate the Contract when they did so on28th June 2010 .”
