Harris v Caladine

The High Court of Australia considered the case of *Harris v Caladine*, brought by the applicant, Mr. Harris, against the respondent, Ms. Caladine. The dispute concerned the validity of a deed of separation and a subsequent divorce, with Mr. Harris seeking to set aside the deed and have the divorce declared void.

The central legal issues before the Court were whether the deed of separation was voidable due to duress or undue influence, and consequently, whether the divorce granted on the basis of the irretrievable breakdown of the marriage, as evidenced by the separation, could be declared void. The Court also had to consider the effect of the *Family Law Act 1975* (Cth) on the ability to challenge a divorce decree.

The Court's reasoning focused on the principles of duress and undue influence in contract law, examining whether Mr. Harris's consent to the deed was vitiated by illegitimate pressure. It was held that the onus was on Mr. Harris to prove the existence of duress or undue influence. The Court also considered the finality of divorce decrees under the *Family Law Act*, noting that such decrees are generally not impeachable on grounds that existed prior to the decree, unless specific exceptions apply. The Court found that the evidence did not establish duress or undue influence to the requisite standard, nor did it satisfy the conditions for setting aside the divorce.

Ultimately, the High Court dismissed the application, upholding the validity of the deed of separation and the divorce decree.
