The result may be that the witness’ account may (even though the witness is attempting to be honest and helpful) actually be a relatively recent fabrication of events. If, under cross-examination, the other side argues that the evidence is a ‘recent invention’ then the only real way to rebut that argument is to produce evidence that, at an earlier time, the witness gave an out-of-court account of the incident, which was consistent with their current evidence. If their evidence is consistent with the earlier statement, it can hardly be a recent invention.
