Viewed in that light, having regard to the nature and purpose of the record, such documents when received by the defendant and placed in the appropriate classification within the various divisions in its file are not, at least when not annotated by the defendant to indicate the date or circumstances of their receipt, 'evidence of any fact stated in the record' within the meaning of s 45A(1)(b), as there is no relevant fact stated in the 'record'. What the document is admissible to prove, by means of its reception in evidence under s 45A, is a fact 'that may be inferred from the record', that fact being that the defendant has received the document and at leaset made use of it to the extent of putting it within its file under one or other of the classifications into which the file is divided."
