45 The respondent submitted that Senior Constable Gordon’s evidence that his opinion had been independently verified by three other experts was led for a non-hearsay purpose as forming part of the foundation of the witness’s opinion. It was argued that the evidence given by Senior Constable Gordon was confined to an expression of his own opinion, having personally engaged in the analysis, comparison and evaluation. His knowledge that the verification process had been undertaken by an independent person served only to reinforce his own opinion and enabled him to express that opinion with greater confidence. It was argued that once admitted for that purpose, the statement became admissible for all purposes, pursuant to s 60(1) of the Evidence Act 2008 .
46 The problem facing the respondent was that the prosecutor made no submission at trial as to the limited purpose for which the evidence was relied upon. More importantly, the jury was not told what, if any, permissible use they could make of the evidence of Senior Constable Gordon that the fingerprint matching had been through three verification processes. How could it now be concluded that the jury understood that the evidence had a non-hearsay purpose when there was no direction from the trial judge as to the limited purpose for which the evidence was relied upon? In the circumstances of the case, the jury may well have considered, wrongly, that the evidence of Senior Constable Gordon about the independent processes taken by other experts was to be accepted as proof of the fact that those independent verification processes had occurred and thus that the process and the evidence was complete. In my opinion, it was incumbent upon the trial judge, particularly in light of the objection taken by the defence, to explain the limited purpose for which the evidence of Senior Constable Gordon was relied upon. He was in error in failing to give that explanation.
47 The situation was aggravated by the judge’s description of Senior Constable Gordon’s evidence, in front of the jury, as amounting to the claim that his work was checked by someone else and the result of that checking was that the other person approved of or reached the same view as he had done.[12] This was tantamount to an endorsement of the use of the evidence for a hearsay purpose without there having been any hearsay notice given or any ruling that, in the circumstances of the case, it fell under an exception, including the exception under s 60 of the Evidence Act .
48 The situation was further aggravated by the judge’s mis-description of the opinion of Senior Constable Gordon as being one of certainty. The evidence that the fingerprint matching had been through three verification processes, when considered by the jury in light of the judge’s charge that the process of fingerprint matching could achieve certainty, would almost inevitably have led to a finding of guilt. That finding was vitiated by the errors I have described with the result that there has been a substantial miscarriage of justice.
