The summing up 153. When Drake J. summed up to the jury, he suggested that there were three "crucial questions". The first, and he made clear that they were not in any order of importance, was whether they believed Julie Mugford? If they were sure that she had told the truth it meant the appellant had planned and carried out the killings. The second was whether they were sure that Sheila Caffell did not kill the members of her family and then commit suicide? The third was whether there was a telephone call in the middle of the night from Nevill Bamber to his son? If there was no such call then it inevitably undermined the whole of the appellant's story and he could have had no reason to have invented it, save to cover up his responsibility for the murders.
154. In dealing with the second question, whether Sheila Caffell may have killed the others and then committed suicide, the judge made clear that answering this question involved a number of different considerations. He suggested that one was "clearly of paramount importance", namely whether the second and fatal shot to Sheila Caffell was fired with the silencer on. If it was, she could not have fired that shot. He made clear that there were other considerations and the jury could come to the conclusion that Sheila Caffell did not carry out the killings "even without reference to the sound moderator". He added that the evidence relating to the sound moderator could, however, "on its own" lead them to conclude that the appellant was guilty.
The application for leave to appeal 155. The appellant sought leave to appeal against his convictions on grounds drawn by those who represented him at trial. The grounds upon which leave was sought related to the judge's summing up, alleging (a) that he had inaccurately assessed significant aspects of the prosecution case and omitted to refer to crucial aspects of the defence case, and (b) that he had with persistence and strength expressed opinions adverse to the defence.
156. Following rejection of the grounds by the single judge, the matter was heard by the full court. The Court rejected the criticisms of the summing up and refused leave. Lord Lane, LCJ giving the judgment observed:
"What is sometimes overlooked is that a direction to the jury reflects the sort of case with which the Judge was dealing. A strong prosecution case will inevitably result in what may be strong comments. Exactly the same with a strong defence case, that may justify strong comments."
157. It seems clear from the judgment as a whole, that the Court were of the opinion that this was a strong prosecution case that merited the comments about which complaint was made. The court, therefore, rejected the proposed grounds and concluded that there was "nothing unsafe or unsatisfactory about this conviction",
158. With one exception, none of the grounds raised before us relate in any way to the matters put before the court on the earlier occasion. The one exception relates to the fact that stories emanating from Julie Mugford had appeared in the press shortly after the trial. This was despite the fact that the prosecution had informed the defence, following discussion with the witness, that she had not sold her story to the press nor was it her intention so to do. One of the grounds relates to the same matter and we will deal with it further when we come to consider that ground. In every other respect, the application for leave to appeal has no relevance to the issues we have to determine.
Events after refusal of permission to appeal 159. At the trial, with justification, Drake J. was critical of the thoroughness of the police investigation in its early stages, when on the jury's verdicts, the police had too readily accepted that this was murder by Sheila Caffell and her subsequent suicide, when the true picture was very different. The Essex Police held an internal police inquiry to look into these criticisms. This was conducted by an officer, Detective Chief Superintendent Dickinson, who subsequently reported to his Chief Constable on the matter. It is alleged that that report reveals evidence that was suppressed by the police, or which, at the very least, was not known to the defence at trial.
