[2002] EWCA Crim 2948
Testimony given on oath or affirmation by a witness at trial was not to be brought into question by evidence that the witness had since trial given a different account of events, unless the court was persuaded that the witness's subsequent account was capable of belief. There was no principle of English law that evidence showing reprehensible conduct of an accused in the past, even the commission by him of a criminal offence, was automatically to be excluded at trial.
