Without attempting to ordain a form of summing up which can fit every case, we observe that in some instances it may help the jury for the judge to explain that the forms of expression are labels applied by the witness to his opinion of the significance of his findings and different experts may not attach the same label to the same degree of comparability."
"It may be necessary to incorporate one or more of the [Atkins] directions:
...
(c) In a case where an expert expresses an opinion in relative terms, a direction in accordance with Atkins ... "
"Bringing these threads together, it is important that you approach the evidence of facial mapping ... with caution. That does not mean that you cannot rely on the expert evidence ... Simply that it needs to be considered ... with care. Mr Evans considers that the imagery evidence lends powerful support to the contention that Man X and Mr Purlis are the same man. But you should remember this, that, as Mr Evans conceded, there is no database ... his opinion is based on his experience and his expertise over many years. Because there is no national database ... or any mathematical formulae, as is the case with fingerprints, or statistics as to the probability of occurrence of particular facial characteristics in the population at large, as in the case of DNA evidence, you cannot gauge the results of an expert's analysis of imagery in the same way as fingerprint or DNA evidence. The fact that there is no statistical database ... is something you should clearly have in mind. But that does not mean that the absence of such a database means that no opinion can be expressed by Mr Evans beyond stating his examination of the images ... An expert who spends many years studying this kind of evidence ... can properly form a judgment as to the significance of what he has found ... It is a judgment based on his experience. It is for you to decide whether to accept the evidence."
"As the prosecution have to prove the defendant's guilt, so that you are sure of it, Mr Purlis does not have to prove he was elsewhere at the time. On the contrary, the Crown must disprove any alibi evidence and satisfy you, so that you are sure, that the alibi relied on by the defendant is wrong. In this case the prosecution have sought to do that by calling Mr Beard who said he left [the address] at 9.45 am. Even if you consider that Mr Purlis is wrong or may be wrong on his timings, or that Mr Beard may be wrong as to when he left ... that does not by itself entitle you to convict the defendant. It is a matter which you may take into account. But you should only convict the defendant if the prosecution have satisfied you, so that you are sure, he was at the HSBC branch, at the bank, at the time the robbery took place and that he committed this crime."
