“The requirement of proof beyond all reasonable doubt does not prevent a jury from inferring, from the facts that have been the subject of direct evidence before them, the existence of some further fact, such as the knowledge or intent of the accused, which constitutes an essential element of the offence; but the inference must be compelling — one (and the only one) that no reasonable man could fail to draw from the direct facts proved.”
“ 20. Read literally, Lord Diplock's dicta might be understood to be saying that an inference was only to be regarded as compelling if all juries, assumed to be composed of those who are reasonable, would be bound to draw such an inference. In short, an inference could only be drawn if no one would dissent from it”. 21. We reject that as an approach to be taken by the judge at the close of the prosecution case, even where the evidence is only circumstantial. The correct approach is to ask whether a reasonable jury, properly directed, would be entitled to draw an adverse inference. To draw an adverse inference from a combination of factual circumstances necessarily does involve the rejection of all realistic possibilities consistent with innocence.”
