"(c) evidence is given of an imputation about the other person made by the defendant (i) on being questioned under caution before charge about the offence with which he is charged, or (ii) on being charged with the offence, or officially informed that he might be prosecuted for it."
"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."
"Even if I am wrong about that, I am satisfied that the manner in which the main witness in this case, Kinvig, was cross-examined clearly attacked his character, and again he was called -- in essence he was called a liar, willing to be recruited to come along to give false evidence against someone he does not even know, and therefore again I take the view that the jury are entitled to hear the character of the defendant upon whose behalf that attack on Kinvig's character has been made. I see no unfairness whatever here."
"You may, if you think it right, also take it into account whether you decide or not that the defendant's evidence to you was truthful. A person with bad character may be less likely to tell the truth, but it does not follow that he is incapable of doing so. So that is a matter for you to decide, to what extent, if at all, his evidence helps you when judging his evidence."
