Badenach & Anor v Calvert

The High Court of Australia, constituted by Kiefel and Keane JJ, considered a dispute between the appellants, Badenach and another, and the respondent, Calvert. The core of the disagreement concerned the interpretation and enforceability of a deed of settlement and release, which the appellants sought to set aside.

The central legal issue before the Court was whether the deed of settlement and release was voidable on the grounds of unconscionable conduct. This required the Court to determine if the respondent had exploited a special disadvantage of the appellants, and if so, whether the respondent had acted unconscionably in procuring the deed.

The Court found that the respondent had not acted unconscionably. Their Honours reasoned that while the appellants may have been in a position of some disadvantage, it was not a "special disadvantage" in the relevant legal sense. Furthermore, the Court held that the respondent had not taken unfair advantage of any such disadvantage. The principles of unconscionable conduct require more than mere inequality of bargaining power; they necessitate the exploitation of a vulnerability that impairs the weaker party's ability to make a rational judgment. The evidence did not support such exploitation in this instance.

Consequently, the High Court dismissed the appeal, upholding the validity of the deed of settlement and release.
