“The old rule, that a party must produce the best evidence that the nature of the case will allow, and that any less good evidence is to be excluded, has gone by the board long ago. The only remaining instance of it is that, if an original document is available in one's hands, one must produce it; that one cannot give secondary evidence by producing a copy. Nowadays we do not confine ourselves to the best evidence. We admit all relevant evidence. The goodness or badness of it goes only to weight, and not to admissibility: Garton v. Hunter [1969] 1 All E.R. 451, per Lord Denning M.R. at 453e; see also Archbold, Criminal Pleading, Evidence and Practice (40th ed.), para. 1001. In our judgment, the old rule is limited and confined to written documents in the strict sense of the term, and has no relevance to tapes or films.”
“The old rule that only the “best” evidence is admissible now survives only in the rule that secondary evidence of the contents of a private document cannot be given without accounting for the non-production of the original. Otherwise all admissible evidence is in general equally accepted, though its weight may be a matter of comment: see Kajala v. Noble …..”
“If the statement in this case, or any other transcription of notes in other cases, is substantially what is in the notes and there is evidence to that effect, then the judge should allow the witness to refresh his memory from the statement or transcription as the case may be. But if, after investigation, it turns out that the statement or transcription bears little relation to the original note, then a different situation arises. The judge in the exercise of his discretion would be entitled to refuse to allow a witness to refresh his memory from such an imperfect source of information.”
“The rule may be stated as follows: a witness may refresh his memory by reference to any writing made or verified by himself concerning and contemporaneously with, the facts to which he testifies. `Contemporaneously' is a somewhat misleading word in the context of the memory refreshing rule. It is sufficient, for the purposes of the rule, if the writing was made or verified at a time when the facts were still fresh in the witness' memory.”
“(1) A person giving oral evidence in criminal proceedings about any matter may, at any stage in the course of doing so, refresh his memory of it from a document made or verified by him at an earlier time if— (a) he states in his oral evidence that the document records his recollection of the matter at that earlier time, and (b) his recollection of the matter is likely to have been significantly better at that time than it is at the time of his oral evidence.” (a) he states in his oral evidence that the document records his recollection of the matter at that earlier time, and (b) his recollection of the matter is likely to have been significantly better at that time than it is at the time of his oral evidence.”
“Section 139 of the 2003 Act … is silent as to the use of a copy of the document that was made or verified by the witness. The unmistakeable intent of the Act being to relax the rule relating to the use of a document by a witness for the purpose of refreshing his memory, it seems inconceivable that the courts will not permit the use of a copy at least in those cases where a copy document could have been used prior to the commencement of the Act.”
“It is submitted that where the original of a document has been lost or destroyed, under s. 139(1) (as at common law), a witness may use a copy if it is proved to be an accurate copy either by the witness himself or by some other person. …”
