“Whether an expert witness giving “ear-print” comparison evidence can admissibly give evidence at a criminal trial beyond a finding that the defendant’s print and the scene lift, are consistent with each other: and in particular expressing an opinion at the scene print left by the defendant.”
“Now, members of the jury, although it is a matter for you, I suggest that you approach Count 1 in this way. First of all consider the evidence of the ear-print. Are you sure that the ear-print was Mr Kempsters? If you are not sure then you must acquit Mr Kempster on Count 1”
“We are going to turn now to deal with counts 2, 3 and 4. The prosecution invite you to work backwards here dealing with count 4 first. For reasons that I will explain, that is the course that I invite you to adopt. To what extent are you entitled to rely on evidence that relates to count 4 of the indictment when considering the defendant’s alleged involvement in the other incidents represented by count 2 and 3. Members of the jury, you may do so if and only if you are sure that the same burglar was involved in each of these three incidents. If you are not sure, then as I have already directed you, you must consider the evidence strictly on a count by count basis. You must consider the evidence on each count quite separately. Now, members of the jury this is very important because counts 2 and 3 will depend on the view you take of count four. If the prosecution have satisfied you so that you are sure of Mr Kempster’s guilt on count 4, then you should go on to consider counts 2 and 3. But if the prosecution have failed to satisfy you of Mr Kempster’s guilt on count 4, then not only would you return a verdict of not guilty on count 4 but you would also have to acquit Mr Kempster on counts 2 and 3 as well.”
