Perpetual Trustee Company Limited v Corbett

In Perpetual Trustee Company Limited v Corbett, the court was tasked with examining the application of proprietary estoppel in relation to certain representations made by a deceased individual to the first defendant, Corbett. The case centred on whether the first defendant had acted to their detriment in reliance on the deceased’s representations, and if the deceased’s representations constituted a contributing cause of the first defendant's actions. Additionally, the court needed to determine whether it would be unconscionable for the deceased's estate to resile from the belief induced by the representations.

The central legal issues revolved around the components necessary to establish proprietary estoppel. The court had to assess whether the deceased's representations amounted to a clear and unequivocal promise or assurance regarding the property in question. Furthermore, it was crucial to evaluate if the first defendant had indeed acted to their detriment in reliance on these representations, and whether the detriment suffered was directly linked to the deceased's assurances. The court also needed to consider if the deceased’s representations were a significant factor in prompting the first defendant's conduct, and ultimately, if permitting the estate to renege on the assurances would be unconscionable.

The court held that the deceased's representations were indeed clear and unequivocal, creating a belief in the first defendant regarding their entitlement to the property. The court found that the first defendant had acted to their detriment in reliance on these representations. The detriment was considered to be directly related to the deceased's assurances, as the first defendant had undertaken significant actions based on the belief fostered by the deceased. The court concluded that the deceased's representations were a contributing cause of the first defendant's actions and that it would be unconscionable for the estate to deny the first defendant’s entitlement to the property. The court ruled in favour of the first defendant, applying the doctrine of proprietary estoppel to grant them a claim against the deceased's estate.

As a result of the court's decision, the estate was ordered to compensate the first defendant for the detriment suffered, thereby recognising the proprietary estoppel claim. The exact quantum of damages and other specific details were to be determined in further proceedings, but the court’s ruling confirmed the applicability of proprietary estoppel in this instance.
