“My conclusions on speaker identity in this case were formed on the basis that there was other evidence that Terry (and others) were in the environment in which the recordings took place and that the task was, in essence, that of verifying as far as possible which of them was speaking at a particular time”
“The precise terms in which the voice expert was instructed are not, at the moment clear. What is clear is that, perhaps for reasons of speed and/or economy, the voice expert was only asked to express an opinion on a number of extracts from the tapes, which dealt with what were, no doubt, considered to be particularly damning remarks. The response from the expert was to set a pre-condition to the expression of any opinion about the extracts from the tapes, namely that there should be some other evidence confirming the presence of one or more of the alleged Defendants.”
“It is extremely important to realise that identification from voice analysis is in no way equivalent to fingerprinting. Identification evidence from speaker analysis should only be used in conjunction with other evidence.” “It is not the same as fingerprint evidence. Always look for other evidence than a voice expert. I re-emphasise that voice identification can only be used where there is other evidence.”
“The failure of the Crown to prove that Terry was in the car at the material time must be elevated by the Not Guilty verdicts into positive, conclusive and irrebuttable proof that Terry was not in the car at the material time.”
“a not guilty verdict is conclusive of the innocence of that particular defendant on that particular charge, but of course is has no further significance, it does not have any impact on the remaining charges which it is your duty to try.”
“The effect of a verdict of acquittal pronounced by a competent court on a lawful charge and after a lawful trial is not completely stated by saying that the person acquitted cannot be tried again for the same offence. To that must be added that the verdict is binding and conclusive in all subsequent proceedings between the parties to the adjudication.”
“The jury ought to have been told of the acquittal and directed that it was conclusive evidence that the appellant was not guilty of arson, and that his confession to that offence was untrue. The jury should have been directed that in deciding the contest between the appellant and the police officers as to the part of the statement referring to the burglary, they should keep in mind that the first part must be regarded as untrue.”
“In the absence of some exceptional feature, such as the effect of an acquittal on the credibility of a confession or the evidence of a prosecution witness, evidence of the outcome on an earlier trial arising out of the same events is irrelevant and, therefore, inadmissible, since it amounts to no more than evidence of the opinion of the jury in the earlier trial: …a fortiori if the earlier trial related to different events.”
“… I consider that provided that a defendant is not placed in double jeopardy …, evidence which is relevant on a subsequent prosecution is not inadmissible because it shows or tends to show that the defendant was, in fact, guilty of an offence of which he had earlier been acquitted. Therefore, I think the relevant passage of Lord MacDermott’s judgment … at 479, the second sentence commencing ‘To that it must be added’ requires the qualification which I have ventured to state.”
“…[The principle of double jeopardy] is not infringed if what the prosecutor seeks to do is to lead evidence which was led at the previous trial, not for the purpose of punishing the accused in any way for the offence of which he has been acquitted, but in order to prove that the defendant is guilty of a subsequent offence which was not before the court in the previous trial.”
“There is no justification for the supposed rule which prevents the prosecution from making an assertion which is inconsistent with the acquittal of the defendant on an earlier and different charge. In the present case it is common ground that the evidence of other complainants is admissible as evidence of similar facts, and accordingly we are not called upon to rule upon the admissibility of such evidence.”
“… Fairness requires that the jury hear all relevant evidence. … Any prejudice to the defendant arising from having to deal a second time with evidence proving facts which were in issue at an earlier trial is simply another factor to be put into the balance. The fact that the previous trial ended in an acquittal is a relevant factor in striking this balance but it is no more than that. It is not, as would be the result of upholding the rule in Sambasivam’s case, conclusive.”
“… it is by no means fanciful to suggest that … a direction to the jury founded on Hay could produce an artificial, unsatisfactory and potentially unfair position in which the jury could find themselves compelled to reach a conclusion which did not accord with the merits of the evidence which they were free to assess. At this stage the position is hypothetical, because Mr Pardoe has stated that if I give the direction for which he contends he will not seek to use it to undermine the voice expert. Nevertheless I can see no logical reason why he would not be entitled to do this, provided that I give the direction he seeks.”
