"... (b) it appears to the court that the physical or mental condition of the accused makes it undesirable for him to give evidence."

"... in an ideal world, with no other factors to be considered, one would want to avoid a situation arising where anyone was put under stress to self-harm. But his own health and welfare is not the only issue, in my judgment, which I should take into account in reaching a judgment as to whether it is undesirable for him to give evidence... there are cases where a defendant's evidence is marginal, of marginal importance. Indeed there are some cases where it may be of no importance at all... In those circumstances one can conceive of a situation where one might say it was undesirable for him to give evidence. But I think the area in which he can give evidence is one of the facts I am entitled to take into account in determining whether in the overall scheme of things it is undesirable. And in this case, whilst there would be an increased risk of self-harm, which I add of itself is not the most serious harm, I think the help he could give is so important that I am not prepared to say that the problems that he has make it undesirable for him to give evidence."
"Is a judge entitled to take into account matters unconnected with a defendant's physical or mental condition when deciding whether or not it was undesirable for him to give evidence pursuant to section 35(1)(b) of the 1994 Act?"
