"Members of the jury I am now going to deal with some specific directions, the first of which, and I deal with it in no particular order, is the question of the defendant's bad character."
"How do you deal with that members of the jury? Well may I first tell you why you heard about it? You heard about it because the prosecution are entitled to say that his history of offending is such that it is more likely that he committed an offence of the type he is now charged with than otherwise. That is for you to judge. The Crown are entitled to put it before you and it is for you to judge whether or not it has that effect. Members of the jury, having heard the evidence for that purpose, you are entitled to take it into account. You are entitled to take it into account but you must decide to what extent, if at all, his character, his previous convictions, help you when you are considering whether or not he is guilty, but bear this in mind, and I stress this: his bad character can't in itself prove his guilt I hope that is obvious. The fact that somebody has been in trouble for taking another person's car and for driving badly or in contravention of the laws on insurance and driving licenses and disqualification on even a number of occasions can't logically prove his guilt and you must not over weigh that element. You are entitled to know about it, you are entitled to take it into account, but as a matter of common sense and fairness may I stress to you it alone could not prove his guilty and you may think, although it is entirely a matter for you, that it is a marginal matter. It is significant but it is not central to your considerations. Please do not over stress it. It would be completely wrong to jump to the conclusion he is guilty just because of his bad character."
"So members of the jury, that is a direction on how to deal with evidence of bad character. I hope it wasn't necessary. I rather hope that you as ordinary normal citizens of this country would be instinctively inclined to the view that to give a dog a bad name is an unfair approach to the attribution of guilt in a criminal case but it is a factor you are entitled to consider."
"(1) In criminal proceedings evidence of the defendant’s bad character is admissible if, but only if— ... (d) it is relevant to an important matter in issue between the defendant and the prosecution..."
"(1) For the purposes of section 101(1)(d) the matters in issue between the defendant and the prosecution include— (a) the question whether the defendant has a propensity to commit offences of the kind with which he is charged, except where his having such a propensity makes it no more likely that he is guilty of the offence ... (2) Where subsection (1)(a) applies, a defendant’s propensity to commit offences of the kind with which he is charged may (without prejudice to any other way of doing so) be established by evidence that he has been convicted of— (a) an offence of the same description as the one with which he is charged, or. (b) an offence of the same category as the one with which he is charged."
"(3) The court must not admit evidence under subsection (1)(d) or (g) if, on an application by the defendant to exclude it, it appears to the court that the admission of the evidence would have such an adverse effect on the fairness of the proceedings that the court ought not to admit it. (4) On an application to exclude evidence under subsection (3) the court must have regard, in particular, to the length of time between the matters to which that evidence relates and the matters which form the subject of the offence charged."
"Old convictions, with no special feature shared with the offence charged, are likely seriously to affect the fairness of proceedings adversely, unless, despite their age, it can properly be said that they show a continuing propensity. There is no minimum number of events necessary to demonstrate such a propensity. The fewer the number of convictions the weaker is likely to be the evidence of propensity. A single previous conviction for an offence of the same description or category will often not show propensity."
"... to assist in the evidence based conviction of the guilty, without putting those who are not guilty at risk of conviction by prejudice. It is accordingly to be hoped that prosecution applications to adduce such evidence will not be made routinely, simply because a defendant has previous convictions, but will be based on the particular circumstances of each case."
