“The evidence of a party as to what terms he understood to have been agreed is some evidence tending to show that those terms, in an objective sense, were agreed. Of course the tribunal may reject such evidence and conclude that the party misunderstood the effect of what was being said and done. But when both parties are agreed about what they understood their mutual obligations (or lack of them) to be, it is a strong thing to exclude their evidence from consideration. Evidence of subsequent conduct, which would be inadmissible to construe a purely written contract (see Whitworth Street Estates (Manchester) Ltd. v. James Miller and Partners Ltd. [1970] A.C. 583) may be relevant on similar grounds, namely that it shows what the parties thought they had agreed. It may of course also be admissible for the same purposes as it would be if the contract had been in writing, namely to support an argument that the terms have been varied or enlarged or to found an estoppel.”
“66. I have no reason to think that (with the possible exception of Mr Leach when he retreated from what he had said to Mr Blue's solicitors) any of the witnesses were doing anything other than stating their honest belief based on their recollection of what was said in relevant conversations. But evidence based on recollection of what was said in undocumented conversations which occurred several years ago is problematic. In Gestmin SGPS SA v Credit Suisse (UK) Limited[2013] EWHC 3560 (Comm) , at paras 16-20, I made some observations about the unreliability of human memory which I take the liberty of repeating in view of their particular relevance in this case: "16. While everyone knows that memory is fallible, I do not believe that the legal system has sufficiently absorbed the lessons of a century of psychological research into the nature of memory and the unreliability of eyewitness testimony. One of the most important lessons of such research is that in everyday life we are not aware of the extent to which our own and other people's memories are unreliable and believe our memories to be more faithful than they are. Two common (and related) errors are to suppose: (1) that the stronger and more vivid is our feeling or experience of recollection, the more likely the recollection is to be accurate; and (2) that the more confident another person is in their recollection, the more likely their recollection is to be accurate. "16. While everyone knows that memory is fallible, I do not believe that the legal system has sufficiently absorbed the lessons of a century of psychological research into the nature of memory and the unreliability of eyewitness testimony. One of the most important lessons of such research is that in everyday life we are not aware of the extent to which our own and other people's memories are unreliable and believe our memories to be more faithful than they are. Two common (and related) errors are to suppose: (1) that the stronger and more vivid is our feeling or experience of recollection, the more likely the recollection is to be accurate; and (2) that the more confident another person is in their recollection, the more likely their recollection is to be accurate. 17. Underlying both these errors is a faulty model of memory as a mental record which is fixed at the time of experience of an event and then fades (more or less slowly) over time. In fact, psychological research has demonstrated that memories are fluid and malleable, being constantly rewritten whenever they are retrieved. This is true even of so-called 'flashbulb' memories, that is memories of experiencing or learning of a particularly shocking or traumatic event. (The very description 'flashbulb' memory is in fact misleading, reflecting as it does the misconception that memory operates like a camera or other device that makes a fixed record of an experience.) External information can intrude into a witness's memory, as can his or her own thoughts and beliefs, and both can cause dramatic changes in recollection. Events can come to be recalled as memories which did not happen at all or which happened to someone else (referred to in the literature as a failure of source memory). 18. Memory is especially unreliable when it comes to recalling past beliefs. Our memories of past beliefs are revised to make them more consistent with our present beliefs. Studies have also shown that memory is particularly vulnerable to interference and alteration when a person is presented with new information or suggestions about an event in circumstances where his or her memory of it is already weak due to the passage of time. 19. The process of civil litigation itself subjects the memories of witnesses to powerful biases. The nature of litigation is such that witnesses often have a stake in a particular version of events. This is obvious where the witness is a party or has a tie of loyalty (such as an employment relationship) to a party to the proceedings. Other, more subtle influences include allegiances created by the process of preparing a witness statement and of coming to court to give evidence for one side in the dispute. A desire to assist, or at least not to prejudice, the party who has called the witness or that party's lawyers, as well as a natural desire to give a good impression in a public forum, can be significant motivating forces. 20. Considerable interference with memory is also introduced in civil litigation by the procedure of preparing for trial. A witness is asked to make a statement, often (as in the present case) when a long time has already elapsed since the relevant events. The statement is usually drafted for the witness by a lawyer who is inevitably conscious of the significance for the issues in the case of what the witness does nor does not say. The statement is made after the witness's memory has been 'refreshed' by reading documents. The documents considered often include statements of case and other argumentative material as well as documents which the witness did not see at the time or which came into existence after the events which he or she is being asked to recall. The statement may go through several iterations before it is finalised. Then, usually months later, the witness will be asked to re-read his or her statement and review documents again before giving evidence in court. The effect of this process is to establish in the mind of the witness the matters recorded in his or her own statement and other written material, whether they be true or false, and to cause the witness's memory of events to be based increasingly on this material and later interpretations of it rather than on the original experience of the events." 67. In the light of these considerations, I expressed the opinion in the Gestmin case (at para 22) that the best approach for a judge to adopt in the trial of a commercial case is to place little if any reliance on witnesses' recollections of what was said in meetings and conversations, and to base factual findings on inferences drawn from the documentary evidence and known or probable facts. 68. A long list of cases was cited by counsel for Mr Blue showing that my observations in the Gestmin case about the unreliability of memory evidence have commended themselves to a number of other judges. In some of these cases they were also supported by the evidence of psychologists or psychiatrists who were expert witnesses: see e.g. AB v Catholic Child Welfare Society[2016] EWHC 3334 (QB) , paras 23-24, and related cases. My observations have also been specifically endorsed by two academic psychologists in a published paper: see Howe and Knott, "The fallibility of memory in judicial processes: Lessons from the past and their modern consequences" (2015) Memory, 23, 633 at 651-3. In the introduction to that paper the authors also summarised succinctly the scientific reasons why memory does not provide a veridical representation of events as experienced. They explained: "… what gets encoded into memory is determined by what a person attends to, what they already have stored in memory, their expectations, needs and emotional state. This information is subsequently integrated (consolidated) with other information that has already been stored in a person's long-term, autobiographical memory. What gets retrieved later from that memory is determined by that same multitude of factors that contributed to encoding as well as what drives the recollection of the event. Specifically, what gets retold about an experience depends on whom one is talking to and what the purpose is of remembering that particular event (e.g., telling a friend, relaying an experience to a therapist, telling the police about an event). Moreover, what gets remembered is reconstructed from the remnants of what was originally stored; that is, what we remember is constructed from whatever remains in memory following any forgetting or interference from new experiences that may have occurred across the interval between storing and retrieving a particular experience. Because the contents of our memories for experiences involve the active manipulation (during encoding), integration with pre-existing information (during consolidation), and reconstruction (during retrieval) of that information, memory is, by definition, fallible at best and unreliable at worst." 69. In addition to the points that I noted in the Gestmin case, two other findings of psychological research seem to me of assistance in the present case. First, numerous experiments have shown that, when new information is encoded which is related to the self, subsequent memory for that information is improved compared with the encoding of other information. Second, there is a powerful tendency for people to remember past events concerning themselves in a self-enhancing light.”
“Hi Darren, I have attached the costs I already gave them, your costs highlighted in yellow. Take a look and let me know if you think it is a good start. We already added 30% to everything. We should reduce it a bit now that the quantity has gone up. Realistically I think we can get a 30-50% saving, but let’s start high, they will try to bully us down so we can pad it and give in 30%. They want the product for end of April and nobody else will be able to supply it in time. Only us! We are happy to share the profit with you 50/50 on all the parts including yours if you cover/front all the costs and handle distribution etc. Matt and I can design out some costs if we get the job and help source cheaper components. We are on a train from 8:30 am. Please have quote or estimate by 10:00 to me on company letter head. Put my number and yours on the quote, they might need to call me. … These costs will need to include packaging. Please structure the quote as follows: [Details were then provided for 64 serving tray sets, 74 aroma tray sets and 20 capsule openers.] Please include a 30% “Discount” on the quote if you think it’s a good idea.”
“We need an extra 4 Aroma Trays, PN 092-012, with this order. So total number should be 34. They will be going to New York for approval for potential future orders, so we want them to be perfect (We [sic] just got this through from Nespresso).”

“In the valley of the normal, events … appear normal in hindsight, although they were not expected, and although we could not have predicted them. This is because the process of understanding reality is backward-looking. An occurrence that was not actively anticipated … triggers a search of memory for a candidate cause … The search stops when a good narrative is found. Given the opposite outcome, the search would have produced equally compelling causes…”
“Hi Natalie, I hope the presentation went well? I realised payment didn’t go out, really sorry, I will do it today and it should be in your account today or tomorrow.”
“Theyre [sic] not talking big numbers for the first year, in the region of 300. Only rolling out to new boutiques and the normal non flagship store will be around 1/4 of the Cannes volume as the non flagship store dont [sic] have the floor space. But the talk was positive and it would be long term view I think. I’m going to focus on product stuff – Darren will no doubt fill you in more on sourcing stuff.”
“Hi Steve, Please meet Darren who we are working with to supply Nespresso. As I mentioned we are working towards production pricing. We are now working with the procurement department at Nespresso to turn the models we supplied into production quantities and production pricing. …Our quantities over 4 years will be 3000-8000 units, with the initial order of 500 (total both styles) this year.”
