"(1) Where, in any proceedings against a person for an offence, evidence is given that the accused- (a) at any time before he was charged with the offence, on being questioned under caution by a constable trying to discover whether or by whom the offence had been committed, failed to mention any fact relied on in his defence in those proceedings; or...
"The defendants explained that their no comment answers, speaking generally because of course they put it in more detail, the Condrons said they were suffering from withdrawal symptoms and relied on Mr Delbourgo, their solicitor's advice that he could see they were suffering from withdrawal symptoms and should not answer questions because in his judgment of their appearance they were unfit for interview despite the known and expressed view of the FME, which means Force Medical Examiner and is in fact a doctor, who comes along to police stations to deal with problems of this sort... The law is, members of the jury, that you may draw such inferences as appear proper from a defendant's failure to mention the points I have referred to in their respective interviews. In each case it is relevant only to the case against the defendant concerned. You do not have to hold it against him or her. It is for you to decide whether it is proper to do so. Failure to mention the points in interview cannot on its own prove guilt but depending on the circumstances you may hold it against him or her when deciding whether he or she is guilty. You should decide whether in the circumstances which existed at the time of the interview the matters were ones which the defendant concerned could reasonably be expected then to mention. Members of the jury, that is all I say at this stage about the law."
"If he failed to mention...when he was questioned, decide whether, in the circumstances which existed at the time, it was a fact which he could reasonably have been expected then to mention.
"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."
"We consider that the specimen direction is in general terms a sound guide. It may be necessary to adapt it to the particular circumstances of an individual case. But there are certain essentials which we would highlight:
"Q. Coming down to the specifics of the allegation, he was in a sufficiently lucid state to be able to explain to you why it was that he had taken drugs, and to repeat that in interview."
