which it ought to have disclosed" which is that the guarantee was precarious with the state of the bank account of the son at the time he arranged for his parents to place their property in guarantee, and the very close working relationship between the bank and the son, and that the parents thought that the limit of their liability was only $50,000, not the full value of their investment property (being of the order of $200,000). The judgment of Deane J, was referred to by other judges. He said, "In the present case ... it was ... evident to the bank that Mr. and Mrs. Amadio stood in need of advice as to the nature and effect of the transaction into which they were entering. It is apparent that any such advice would have included the importance to a guarantor of ascertaining from the bank the state of the customer's account which was being guaranteed and any unusual features of the account. If such information had been obtained by Mr. and Mrs. Amadio, they would not, on the evidence and in the light of the learned trial judge's finding, have entered into the guarantee/mortgage at all. The whole transaction should properly be seen as flowing from the special disability which was evident to the bank and as being unfair, unjust and unreasonable." The customer's account stated here is that of their son who brought the bank guarantee documents to his parents. The bank knew of the poor state of the son's business accounts, and the bank and the son had a history of closely linked business relations with each other. Wilson J agreed with Deane J. Dissenting opinion Dawson J delivered a dissenting judgment in which he said, "it is my view that the appellant bank was not guilty of any non-disclosure amounting to a breach of duty on its part" and that the facts did not point to the Amadios having been disadvantaged and that, therefore, the bank was not guilty of either unconscionable conduct or misrepresentation.
