"O’Callaghan was not an informant in this case and, so far as it is known, is not an informant."
"There are two counts here, three defendants. You must give separate consideration to each count and separate consideration on count 2 to the cases of Mr Lysser and Mr Walton and reach independent verdicts in respect of all three defendants. That does not mean to say you look at a defendant in isolation because, of course, there is a mass of overlap of evidence in this case and indeed I will refer to it. It may be that were you sure that one person was guilty that might be strong evidence in relation to the other person but only evidence. Likewise, if someone is not guilty it may be strong evidence in support of another defendant but not conclusive."
"I move now to what is really fact but it may be worth dealing with now because it is close to the law. As I have said, the guilt or otherwise of one defendant is not, in any way, conclusive of the guilt or otherwise of another defendant. It may be that it is a conclusion that one would reach. If, for instance, Mr Lysser was guilty then you might think it would be very difficult to see how Mr Walton would not have been part of it. Likewise, of course, if Mr Walton is guilty you will want to ask yourself what was Mr Lysser doing in the car? You will want to look at it from the perspective of a person, if he were guilty, if Mr Walton was guilty why would he want Mr Lysser there to know where he was collecting his drugs from, even if Mr Lysser did not know they were drugs, there is no need for Mr Lysser to be there? (sic) As for Mr O’Connor (sic), if Mr Walton was guilty would he have used Mr O’Connor? (Sic) What is the point of Mr O’Connor collecting those items and putting them in the car? (sic) How does it help any enterprise? Because of course, if Mr Walton is guilty Mr O’Callaghan does not know what he is going to say were he to be stopped or ever arrested about the matter. He has no guarantee that Mr Walton will choose to make no comment when, within hours after them being put in there, he is stopped. Mr O’Callaghan does not know, even in the defence statement there was no mention of him, a man in a white polo shirt so why would Walton, were he guilty, want O’Connor involved? (I keep calling him O’Connor, O’Callaghan involved.) Why should he want to involve him? Why, if you looked at Mr O’Callaghan’s case, why would he want Mr Lysser there? He can say to Mr Walton, look, I wonder if we can just have a personal chat. I am sorry about this Mr Lysser, see you back at the Priory in half an hour. If you start looking at it from one defendant’s point of view if he is guilty it may be that it becomes very very difficult to see how it could be that the prosecution are wrong when they say that all three people engaged in the day in the transfer of the drugs from Oliphant Street into the jeep."
"As I say there is no evidence to show that he knew about it. Of course, if Mr Lysser is guilty then that may be evidence, indeed, very strong evidence, against Mr Walton. When you are considering Mr Walton’s case you do not look at this document. You do so, however, you may think with considerable care, in respect of Mr Lysser’s case." 10. At another place in the summing up the judge dealt with the fact that the appellant had not named O’Callaghan in interview or the defence statement. This is what he said at pp. 8 and 9 of the transcript: "
"Although, as I have just said, you cannot use this fact in support of the case against Walton, it is something you are entitled to take into account in O’Callaghan’s favour in assessing, as against O’Callaghan, Walton’s evidence that he is not guilty and his suggestion that O’Callaghan has sought to exculpate himself by falsely blaming Walton. When a defendant gives evidence against another defendant you cannot act on that evidence against that other defendant unless you are sure that it is true. On the other hand if you think the evidence may be true but are not sure it is true, then, although you must not use it against the other defendant you will use it in favour of the first defendant. There is nothing strange about that. It is simply a reflection of the fact that the burden of proof is on the prosecution, which means you can only act against a defendant on evidence you are sure about but you will act on evidence in favour of a defendant which you think may be true and which, therefore, the prosecution has not made you sure is untrue."
