The decision of the court was given by Steyn J. Having identified the central issue from the outset, much of the decision was a detailed review of the evidence to consider to what extent the bank knew, or ought to have known, of the fraudulent designs of Quincecare's chairman. This included a review of the dealings of the bank with Mr Stiller, and also consideration of expert evidence of the usual customs and practices of bankers. Although the company and its guarantor advanced a number of different defences, all of which were addressed in the judgment, the most important aspect of the judgment in terms of jurisprudence was the decision in relation to whether or not the bank was in breach of its duty to its customer by failing to be alive to possible fraud, and the test laid down by the court to be applied. The judgment briefly reviewed the principal authorities, being
Selangor United Rubber Estates Ltd v Cradock (No 3) [1968] 1 WLR 1555 and
Karak Rubber Co Ltd v Burden (No 2) [1972] 1 WLR 602, and the more recent first instance decision in
Lipkin Gorman (a firm) v Karpnale Ltd [1987] 1 WLR 987 (subsequently appealed after the decision in
Quincecare was handed down). In an oft-cited passage, Steyn J held that: He went on to stress that "trust, not distrust, is also the basis of a bank's dealings with its customers", citing with approval similar comments from
Bowen LJ in
Sanders Bros v Maclean & Co (1883) 11 QBD 327 at 343. Accordingly, he dismissed the defences and counterclaims of the defendants and gave judgment for the bank in the amount of the loan, plus interest and costs. ==Authority==
