"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."
"22. It appears to us that ultimately the question for the judge on any application for a stay in a case of this kind is essentially whether in all the circumstances of the case a fair trial is possible notwithstanding the delay. 23. We think that there is force in Mr Crozier's point which was not taken in either B or Hooper, that once the issue has been raised it must be for the Crown to satisfy the court that a fair trial is still possible. Nevertheless it must be for the defendant to raise the issue and to identify those respects in which he says that a fair trial is not possible. We are not persuaded that this approach is in substance different from that adopted in Attorney General's Reference No 1 of 1990. The Recorder himself had this point in mind. He held, in our view correctly, that in this case it made no difference to his decision whether he approached the case on the basis of a legal burden of proof on the balance of probabilities lying on the defendant, or simply as an evidential burden on the defendant."
"I am conscious of the critical importance of ensuring that the defendant has a fair trial, of ensuring that the allegations against him are of sufficient clarity and particularity that they can be fairly left to the jury, and that he can have a fair opportunity of challenging them in what of course are difficult circumstances for the defence."
