 The leading case on undue influence is considered to be "Lloyds Bank Ltd v Bundy"; the case is remarkable in that judgment was put forth that English law should adopt the American approach that all impairments of autonomy should fall under the single principle of "inequality of bargaining power".In this case, Bundy agreed to increase the mortgage on his farmhouse in order to maintain the line of credit being extended to his son's business.The question was whether the contract leading to the repossession of Bundy's farmhouse was voidable due to pressure brought by the bank.
