"Is it fair that the prosecution should be allowed to adduce the voice identification evidence in the light of the evidence given by the defence expert Mr Duckworth?"
"It is in my view unrealistic to expect that the police aided or unaided to assemble a collection of voices where there are not differences in pitch, timbre, flow, forcefulness. Obviously there may be cases where the accused's voice is so markedly different from the other voices that one would be driven to say that it was not a fair test that in such cases it would be right to exclude the evidence under section 78. In my view this is not such a case and Mr McCarraher was justified in making the point that two of the three witnesses failed to identify the accused's voice. Therefore I am not prepared to exclude the voice identification evidence under section 78."
"The final point, not raised by Mr McCarraher but myself, was whether it is appropriate that Mr Duckworth should be permitted to repeat his evidence in front of the jury. Mr McCarraher said that he was minded to argue the point at the first hearing of the case before Judge MacKean, but Judge MacKean in the course of the voir dire, which he held, expressed the view that no doubt the jury would find Mr Duckworth's evidence helpful, so Mr McCarraher desisted from arguing the point.
"An expert's opinion is admissible to furnish the court with scientific information which is likely to be outside the experience and knowledge of a judge or jury. If on the proven facts a judge or jury can form their own conclusions without help, then the opinion of an expert is unnecessary. In such a case, if it is just out of the scientific jargon, it may make judgment more difficult."
"It is for all these reasons that I have come to the decision that Mr Duckworth's evidence is not admissible."
"It is to be noted that Lawton LJ there referred to a jury forming their own conclusions 'without help'. Where, for example, there is a clear photograph and no suggestion that the subject has changed his appearance, a jury could usually reach a conclusion without help. Where, as here, however, it is admitted that the appellant had grown a beard shortly before his arrest, and it is suggested further that the robber may have been wearing clear spectacles and a wig for disguise, a comparison of photograph and defendant may not be straightforward. In such circumstances we can see no reason why expert evidence, if it can provide the jury with information and assistance which they would otherwise lack, should not be given. In each case it must be for the judge to decide whether the issue is one on which the jury could be assisted by expert evidence, and whether the expert tendered has the expertise to provide such evidence."
"In each case it must be for the jury to decide whether the issue is one on which the jury could be assisted by expert evidence."
"There are a number of similarities between Mr Hersey and the remaining 11 speakers on [the video] in respect of the accent used. It is reasonable to suggest that all the speakers come from the same broad geographical region.
"There are three reasons why Mr Hersey's speech is likely to stand out intrinsically from the remaining 11 speakers on [the video].
"In a case of visual identification the courts have laid down that juries shall be told that there is a special need for caution before convicting an accused person in reliance solely on the correctness of an identification. They have to be warned that mistakes can happen in the case of a visual identification and that mistakes have happened. We all know that. They are broadcast, talked about, written about and rightly so.
"To sum it up, this case rests upon Mr Whiting's identification of the defendant's voice. The law does not require that there shall be any other evidence apart from a witness's identification. You may convict solely upon Mr Whiting's identification but please bear in the forefront of your minds all those matters of warning that I have mentioned to you. That is all I want to say about that and I am going to remind you now of the evidence."
"I have now almost finished my summing-up. I must say a word about the voice identification parade of which criticism has been made by Mr Stopa. Let me say a word or two. There is some substance, you may thing, in Mr Stopa's point that Mr Whiting in identifying the accused on the tape when the tapes were played to him was doing no more than identifying the voice of the accused which was a voice that was familiar to him as being the voice of a customer in his shop. Mr Stopa says that the crucial point in this case is whether he was correct in his identification of the voice on the evening of the robbery. He says that there is no inconsistency between his having been wrong in that identification but right in his identification of the accused as the speaker on the tape. That is a point that you should have regard to. It is entirely up to you whether you find that the recognition by Mr Whiting of the accused's voice when he listened to the tape adds to the strength of the prosecution case against the accused that he was the robber."
