Sometimes during the testimony of a witness, the witness may be questioned about statements he previously made outside court on an earlier occasion, to demonstrate either that he has been consistent or inconsistent in his account of events. The Act did not change the circumstances in which such statements could become admissible in evidence (which are still prescribed in the Criminal Procedure Act 1865), but it did change the evidential effect of such statements once admitted. Formerly, such statements were not evidence of the facts stated in them (unless the witness agreed with them in court): they only proved that the witness had kept his story straight or had changed his story, and so were only evidence of his credibility (or lack of it) as a witness. They were not hearsay. Under the 2003 Act, however, such statements are now themselves evidence of any facts stated in them, not just of credibility, and so are now hearsay.
