“Cross-examination of – typically – the investigating police officer to establish the bad character of a person who is neither a party nor a witness commonly occurs in practice. The most obvious example is in cases of homicide. Where questions as to character are put to a witness (especially if he is the defendant), the standard view is that their relevance is to credibility. The reality, however, is that where the defence to a charge of murder is self-defence and it is elicited that the deceased had a series of convictions for serious offences of violence, the relevance of this evidence is that it goes to disposition (and see R v Lee, 62 Cr.App.R.33,CA – evidence admitted, on charge of burglary, of bad character of persons not called who had access to premises). If the charge were only one of wounding with intent, contrary to s.18 of the Offences against thePerson Act 1861 , and similar matters were put to the alleged victim, it is submitted that they should be regarded as relevant both to disposition and credibility.” 22. Lord Steyn commented: “This is a good example of the potential relevance of a propensity of an individual to the issues in a criminal case.”
