36 While this seems to me to have played no part in the trial Judge's reasoning, there was some argument, in the course of the appeal, as regards the question whether or not there was evidence upon which a jury might conclude, beyond reasonable doubt, that each statement was knowingly false. In my opinion, there was. The investigation made by the police was one into the circumstances of Moore's death. It is, no doubt, true that there was no evidence to suggest that the police investigation focused on steps that might have been taken after Moore was found slumped on his bed. However, at the time at which the statements were made (at a very early stage in the investigation), the failure immediately to give CPR was plainly a matter of potential relevance to the investigation. As I have said, there is no dispute as regards the proposition that it was open to the jury to find that, if each statement was false in the respect alleged, it was false in a material particular. In those circumstances, and given that each of the five respondents omitted any mention of what had been done (or not done) after Pietersen's arrival, and, instead, suggested that CPR had commenced immediately and continued until the paramedics arrived, it seems to me that it was open to the jury to infer that each falsehood had been deliberate, in the course of a joint attempt to conceal the fact of the failure immediately to administer CPR. This inference is strengthened by the fact that each of the respondents provided a supplementary statement setting out the true position at about the same time in early January.
