 When the son's business failed, the Amadios had the contract set aside due to unconscionable dealing by the bank.The court held that the bank manager knew about the “special disability” of Amadios, referring to their advanced age, lack of business acumen, lack of fluency in written English, and their reliance on their son's [inadequate] disclosure of his finances.A special disability is one which seriously affects the ability of the person subject to it to make sensible decisions of their own best interest.
