"100Non-defendant's bad character (1) In criminal proceedings evidence of the bad character of a person other than the defendant is admissible if and only if — (a) it is important explanatory evidence, (b) it has substantial probative value in relation to a matter which — (i) is a matter in issue in the proceedings, and (ii) is of substantial importance in the context of the case as a whole, or (c) all parties to the proceedings agree to the evidence being admissible. (2) For the purposes of subsection (1)(a) evidence is important explanatory evidence if — (a) without it, the court or jury would find it impossible or difficult properly to understand other evidence in the case, and (b) its value for understanding the case as a whole is substantial."
"It rather looked to me as though you were saying 'Come on' twice. Do you agree with that, or do you not know?"
"I remind myself that [the appellant] has given unchallenged evidence that he has only one conviction, not for violence, and he has observed on a number of occasions during the course of his evidence that he has never before been involved in a situation of violence and he has not been challenged on that point. In the circumstances I do not consider that further evidence on that specific point is admissible. In coming to that judgment, I do not regard in any sense that it has deprived him of the point that is sought to be made on his behalf, that he has never committed a violent act – an offence of violence – because, of course, the jury know that. I will warn the jury that the fact that he has a conviction is not something that they should allow themselves to be prejudiced against him, and it does not in any sense made it any more likely that he is guilty of this offence. In my judgment the jury have sufficient admissible evidence to consider the point that has been made on behalf of [the appellant] and I do not consider it permissible or admissible for a party to adduce evidence that is of partial character – a specific aspect of his character – in circumstances where that defendant is not of good character."
