“It is not in dispute that if the loan documents were indeed forgeries and the account given by Nano in his evidence in the court in St. Vincent of the transaction on31 January 1979 at the Hotel du Rhone in Geneva was a fabrication, the St. Vincent judgment was obtained by fraud. But it is submitted for the bank that the language of section 9(2)(d) must be construed as qualified by the common law rule that the unsuccessful party who has been sued to judgment is not permitted to challenge that judgment on the ground that it was obtained by fraud unless he is able to prove that fraud by fresh evidence which was not available to him and could not have been discovered with reasonable diligence before the judgment was delivered. Here, it is said, there is no such fresh evidence. This is the rule to be applied in an action brought to set aside an English judgment on the ground that it was obtained by fraud. The rule rests on the principle that there must be finality in litigation which would be defeated if it were open to the unsuccessful party in one action to bring a second action to re-litigate the issue determined against him simply on the ground that the opposing party had obtained judgment in the first action by perjured evidence. Your Lordships were taken, in the course of argument, through the many authorities in which this salutary English rule has been developed and applied and which demonstrate the stringency of the criterion which the fresh evidence must satisfy if it is to be admissible to impeach a judgment on the ground of fraud. I do not find it necessary to examine these authorities. The rule they establish is unquestionable and the principle on which they rest is clear.”
