“Where it is clearly established by fresh evidence that the court was deliberately deceived in relation to the credibility of a witness, a fresh trial will be ordered where there is a real danger that this affected the outcome of the trial.” 90. As Mr Davies observed in his skeleton argument, the Hamilton case was not cited to the Court of Appeal in the Royal Bank of Scotland case and the test set out by Aikens LJ was agreed between counsel in that case. 91. Furthermore, in the Sharland case[2016] AC 871 , para 32 Baroness Hale DPSC, citing Smith v Kay (1859) 7 HL Cas 750, said that “a party who has practised deception with a view to a particular end, which has been attained by it, cannot be allowed to deny its materiality”. 92. That statement was cited with approval by Lord Clarke of Stone-cum-Ebony JSC, with whom the other Justices of the Supreme Court agreed, in Zurich Insurance Co plc v Hayward[2017] AC 142 , para 37. 93. In those circumstances, I am inclined to agree with Mr Davies that the test was over-stated in the Royal Bank of Scotland case and that the proper approach is that laid down by the Court of Appeal in the Hamilton case.” “Where it is clearly established by fresh evidence that the court was deliberately deceived in relation to the credibility of a witness, a fresh trial will be ordered where there is a real danger that this affected the outcome of the trial.”
