“… Of course it has been recognised always that it is wrong for a judge to descend into the arena and give the impression of acting as advocate. Not only is it wrong but very often a judge can do more harm than leaving it to experienced counsel. Whether his interventions in any case give ground for quashing a conviction is not only a matter of degree, but depends to what the interventions are directed and what their effect may be. Interventions to clear up ambiguities, interventions to enable the judge to make certain that he is making an accurate note, are of course perfectly justified. But the interventions which give rise to a quashing of a conviction are really threefold; those which invite the jury to disbelieve the evidence for the defence which is put to the jury in such strong terms that it cannot be cured by the common formula that the facts are for the jury ... The second …where the interventions have made it really impossible for counsel for the defence to do his or her duty in properly presenting the defence, and thirdly, cases where the interventions have had the effect of preventing the prisoner himself from doing himself justice and telling the story in his own way.”
“... In analysing the overall effect of the interventions, quantity and quality cannot be considered in isolation but will react the one upon the other; but the question which is posed ultimately for this court is: ‘ Might the case for the defendant as presented to the jury over the trial as a whole, including the adducing and testing of evidence, the submissions of counsel and the summing-up of the judge, be such that the jury's verdict might be unsafe?’ He continued: “We add that if the court is driven to the conclusion that the defendant has not had a fair trial, when the matter is looked at in the round, the natural conclusion will be that the verdict is unsafe because our system of criminal justice is dependent upon the fundamental principle of the provision of a fair trial. To allow an appeal in such circumstances, even though the evidence for the prosecution may have been exceedingly strong, is not to allow an appeal on a technicality, but to allow it upon a fundamental principle which underlines our criminal justice system.”
“ It is not a sufficient answer in our judgment to say that because questions were likely to be put in cross-examination, there was no harm in them being put by the judge in the course of the appellant's evidence in-chief. We do not suggest that any intervention in the course of evidence in-chief, other than by way of clarification, must render a conviction unsafe. However, there are good reasons why a judge should be particularly careful about refraining from intervening during a witness' evidence in-chief, except insofar as it is necessary to clarify, to keep the evidence moving on and, if necessary, to avoid prolixity or irrelevancies. The first is that it is for the prosecution to cross-examine, not for the judge. The second is that the right time for the prosecution to cross-examine is after a witness has given his evidence in-chief. It would be unthinkable for prosecuting counsel to jump up in the middle of a witness' evidence in-chief and seek to conduct some hostile cross-examination. This is not merely in order to preserve an orderly trial. There is a more important, fundamental reason. A jury will inevitably form a view of each witness as the case goes along. As the witness is giving his or her evidence in-chief, so the jury will be absorbing that account and forming their own impression of the witness.”
“Ill health The Judge fairly sought to balance the applicant’s fair trial rights and the public interest in a case where very little of the prosecution evidence from witnesses called at trial touched on Mr Ellis’s case and where it did he was present. The use of the CVP link in those circumstances was appropriate, was fully explained to the jury and indeed the jury had seen prosecution witnesses give evidence by that means. Mr Ellis’s interests were fully protected by defence counsel. I note that most of the evidence him was foreshadowed in the exhibits and that it was the interpretation of those exhibits by the jury that consisted of the majority of the case against him. Further, the Judge did not err in exercising his discretion not to sever Mr. Ellis from the other defendants and considered the competing factors as set out in the governing case law. A trial judge has a discretion as to whether a trial should take place or continue in the absence of the accused and I agree with the Respondent that the judge exercised that discretion within lawful bounds, taking account of the submissions on Mr Ellis’ behalf. There was no arguable error in the Judge’s three rulings on the DCS (25 Feb, 2 March and 7 March).”
