Case No. IP-2021-000073

16.Similarly, I do not understand there to be any dispute about the law as regards the implication of terms in a contract. The leading authority remains Marks & Spencer plc v BNP Paribas Securities Services Trust Co (Jersey) Ltd [2015] UKSC 72, [2016] AC 742. However, a comprehensive and helpful summary of the principles deriving from this and other authorities was recently provided by Carr LJ (with whom Coulson LJ and King LJ agreed) in Yoo Design Services Limited v Iliv Realty Pte Limited [2021] EWCA Civ 560 at [47]-[52]. After cautioning at [47] that: “The implication of contractual terms involves a "different and altogether more ambitious undertaking" than the exercise of contractual interpretation which identifies the true meaning of the language in which the parties have expressed themselves: the interpolation of terms to deal with matters for which, ex hypothesi, the parties have themselves made no provision. It is because the implication of terms is so potentially intrusive that the law imposes strict constraints on the exercise of the "extraordinary" power so to intervene…”,Carr LJ provided the following guidance at [51]:“[51] In summary, the relevant principles can be drawn together as follows:i) A term will not be implied unless, on an objective assessment of the terms of the contract, it is necessary to give business efficacy to the contract and/or on the basis of the obviousness test;ii) The business efficacy and the obviousness tests are alternative tests. However, it will be a rare (or unusual) case where one, but not the other, is satisfied;iii) The business efficacy test will only be satisfied if, without the term, the contract would lack commercial or practical coherence. Its application involves a value judgment;iv) The obviousness test will only be met when the implied term is so obvious that it goes without saying. It needs to be obvious not only that a term is to be implied, but precisely what that term (which must be capable of clear expression) is. It is vital to formulate the question to be posed by the officious bystander with the utmost care;v) A term will not be implied if it is inconsistent with an express term of the contract;vi) The implication of a term is not critically dependent on proof of an actual intention of the parties. If one is approaching the question by reference to what the parties would have agreed, one is not strictly concerned with the hypothetical answer of the actual parties, but with that of notional reasonable people in the position of the parties at the time;vii) The question is to be assessed at the time that the contract was made: it is wrong to approach the question with the benefit of hindsight in the light of the particular issue that has in fact arisen. Nor is it enough to show that, had the parties foreseen the eventuality which in fact occurred, they would have wished to make provision for it, unless it can also be shown either that there was only one contractual solution or that one of several possible solutions would without doubt have been preferred;viii) The equity of a suggested implied term is an essential but not sufficient pre-condition for inclusion. A term should not be implied into a detailed commercial contract merely because it appears fair or merely because the court considers the parties would have agreed it if it had been suggested to them. The test is one of necessity, not reasonableness. That is a stringent test.”
