Dunstan v Proudman

The case of Dunstan v Proudman involved a dispute concerning the equitable remedies of a trust, charge, or proprietary estoppel. The respondents, Dunstan and Proudman, moved in with the appellant, an elderly man, under oral agreements that they would pay for an extension to his house and subsequently rent out their own house. The respondents sought equitable relief to enforce the agreements. The matter was heard in the High Court of Australia.

The central legal issues before the court were whether the circumstances gave rise to an enforceable trust, charge, or proprietary estoppel. The court considered whether there was any promise, representation, or conduct that would found such equitable remedies. The court had to determine if the appellant's conduct or representations could be relied upon by the respondents to create a binding obligation.

The court found that there was no promise, representation, or conduct that could form the basis of a trust, charge, or proprietary estoppel. The court held that the mere fact that the respondents had relied on the appellant's representations and made financial contributions was not sufficient to create an equitable obligation. The court emphasised that for proprietary estoppel to apply, there must be a clear and unequivocal promise or representation that induced the respondent to act to their detriment. In this case, there was no such promise or representation. Therefore, the court dismissed the respondents' claims.

The High Court upheld the decisions of the lower courts and dismissed the appeal. The court held that the respondents had not established any equitable remedy in their favour. The oral agreements were not sufficient to create a binding obligation, and the respondents' claims were accordingly dismissed.
