“As you know, Mr Orr has suffered from ill health, specifically depression for a number of years, which as you probably know can be and very often is extremely debilitating and very unpleasant. This fact has had an impact on these proceedings at various stages. In this trial attempts have been made to minimise the difficulties it was likely to cause [the appellant] in the trial process, such as taking more frequent breaks and allowing him to sit with his legal advisers. When the time came, he chose to give evidence on his own behalf and did so for many hours, spread over three court days. The morning after he had finished his evidence in chief... he was clearly not in a fit condition to continue. That remained the position over the course of the following days, during which he was examined by two experienced consultant forensic psychiatrists... They have each independently formed the same firm opinion, namely that [the appellant] was not fit to continue giving evidence, and most particularly not fit to undergo cross examination. They are both equally of the firm opinion that his condition is entirely genuine and lies outside his control. No one suggests otherwise. In view of their opinions, it seemed to me there was no prospect that this position would change within a manageable time in the context of this trial. I therefore decided that he could not continue with his evidence and that the trial should move on to its next stages... It follows from what I have said, and you must accept it from me, that [the appellant’s] inability to continue giving evidence is in no way his fault. He told me, and I do not doubt it, that he would like to carry on giving evidence and to have the opportunity of answering questions put in cross examination... It means that you only have his evidence in chief to consider and that the prosecution has not had the opportunity to test his evidence in cross examination. But that is just a consequence of the unusual circumstances of this case. What you must not do is speculate about the answers he may have given had he been cross examined...”
