Louth v Diprose

The High Court of Australia considered an appeal concerning the equitable doctrine of unconscionable conduct in the context of a gift. The dispute involved a gift of land made by the respondent, Mr. Diprose, to his niece, Ms. Louth, the appellant. Mr. Diprose alleged that he was under a special disadvantage when making the gift and that Ms. Louth had unconscionably exploited this disadvantage.

The central legal issue before the Court was whether the gift of land could be set aside on the grounds of unconscionable conduct. This required the Court to determine if Mr. Diprose was suffering from a special disadvantage that rendered him susceptible to the influence of Ms. Louth, and if Ms. Louth had actual or constructive knowledge of this disadvantage and proceeded to exploit it to her benefit.

The Court, applying the principles of equitable unconscionability, found that Mr. Diprose was indeed under a special disadvantage due to his infatuation with Ms. Louth and his desire to please her, which significantly impaired his ability to make a rational decision regarding the gift of his property. The Court held that Ms. Louth was aware of Mr. Diprose's emotional vulnerability and, by encouraging and accepting the gift in circumstances where she knew it was not a free and voluntary act, she had unconscionably exploited his disadvantage. The Court affirmed that equity will intervene to set aside transactions where one party is under a special disadvantage and the other party takes unconscionable advantage of that disadvantage.

The High Court allowed the appeal, setting aside the gift of land and ordering that the property be transferred back to Mr. Diprose.
