In a recent decision, the Commercial Court has rejected a party’s witness evidence on a key issue, commenting that the fact the witnesses did not refresh their memories from contemporaneous documents meant their evidence was “far less likely to be reliable than it might otherwise have been”: Global Display Solutions Ltd v NCR Financial Solutions Group Ltd [2021] EWHC 1119 (Comm).
The witness statements in the present case were signed before 6 April this year and so were not subject to the new requirements relating to trial witness statements in the Business and Property Courts, at Practice Direction (PD) 57AC and Appendix, including in particular the requirement to list documents a witness has referred to or been referred for the purpose of providing the evidence set out in their statement. However, it is clear that the judge did not consider the new requirements to affect his decision. He commented that the new rules contemplate that witnesses will be shown contemporaneous documents, particularly those they had seen at the time of the relevant events.
It is true that the new PD and Appendix do not preclude a witness being shown contemporaneous documents. However, the general tenor of the new provisions is to discourage over-reliance on documents in preparing witness evidence, and to distinguish between what is spontaneous recollection and what may have been influenced by reviewing documents, with the implication appearing to be that the former is somehow preferable.
The witness evidence working group’s implementation report, in presenting opposing views among the group as to the proposed requirement to list documents to which the witness has been referred, noted that those in favour took the view that the court should know “the extent to which what is presented as factual witness testimony in chief” may have been influenced by going through the documents. It added that the question of what documents to show a witness should be given careful thought because “it may affect the weight to be given to what the witness will claim as recollection to have an understanding of the extent to which it was spontaneous, recollection refreshed from documents the witness saw at the time, or testimony prompted by reviewing documents the witness did not see at the time”. It noted a concern among those opposed to the new requirement that a court might draw adverse inferences if the list indicated that a witness had been shown large numbers of documents.
The recent decision therefore illustrates the difficult judgments that will need to be made in any given case as to whether a witness should be shown contemporaneous documents, in the hope that by refreshing their memory they will be able to give more complete and ultimately more reliable evidence, or whether by doing so there is a risk that a court might consider their evidence to be primarily reconstruction rather than recollection and potentially discount it on that basis. Where a decision is taken to show a witness documents, parties should also bear in mind the new requirement at paragraph 3.7 of the Appendix to identify (where practicable) any documents used to refresh a witness’s recollection on important disputed matters of fact.
