Couchy v del Vecchio

Gaudron and Gummow JJ of the High Court of Australia considered a dispute between Couchy and del Vecchio concerning the interpretation and enforceability of a deed. The core of the disagreement revolved around whether the deed, which purported to settle a prior dispute between the parties, was valid and binding, or if it was vitiated by certain circumstances.

The primary legal issues before the Court were whether the deed was void or voidable due to alleged duress or undue influence exerted by del Vecchio over Couchy, and consequently, whether Couchy was entitled to have the deed set aside. The Court also had to consider the effect of Couchy's subsequent conduct in relation to the deed, and whether such conduct amounted to a ratification of the agreement, thereby precluding him from seeking to set it aside.

Their Honours analysed the principles of duress and undue influence, emphasising the need for Couchy to demonstrate that his will was overborne by illegitimate pressure or unfair advantage. They considered the evidence presented regarding the circumstances surrounding the execution of the deed, including the nature of the prior dispute and the advice Couchy received. The Court also examined the doctrine of ratification, noting that even if a contract is voidable, a party may lose the right to rescind if they subsequently affirm the contract with full knowledge of their rights.

The High Court ultimately found that Couchy had not established the necessary elements for duress or undue influence, and that his subsequent actions indicated a ratification of the deed. Accordingly, the appeal was dismissed.
