What is the effect of the hearsay evidence rule on the testimony of a witness in a criminal case?

"If a man admits something of which he knows nothing it is of no real evidentiary value." Not all of the questions and answers indicate that the wife was speaking of something of which she knew nothing. Some questions are answered of direct knowledge. She had some personal knowledge in the area of which she spoke. There is one answer in which belief is indicated and others where it may be a reasonable inference. The man of whom she spoke was her husband with whom she lived. Some of the questions and answers have significance for the fact that they were said and not necessarily for the truth of what was said and, for such purpose, the hearsay evidence rule has no application. See Subramanian v. Public Prosecutor, [1956] 1 W.W.R. 970 (P.C.). All in all I have looked at this evidence with care and with the hearsay evidence rule in mind.
