Doueihi v Construction Technologies Australia Pty Ltd [2016] NSWCA 105

Doueihi v Construction Technologies Australia Pty Ltd [2016] NSWCA 105

A proprietary estoppel may arise where a party is encouraged or permitted by property owners to assume, and does assume, they will be granted a long-term interest in premises, and acts to substantial detriment as a result; it is not necessary that the party assumed a legally binding relationship or formal contract would exist. Where family practices eschew formality, it is not unreasonable to rely on those arrangements, and it would be unconscionable for the property owners to deny the interest after the induced expenditure and reliance. The orders of the primary judge should be upheld as the prerequisites for equitable intervention were satisfied in the circumstances.

Legal Issues

  1. 1 ['Whether the primary judge erred in finding proprietary estoppel by encouragement in favour of the respondent (CTA) against all appellants' 'Whether DHJPM v Blackthorn compelled dismissal of the proprietary estoppel claim' 'Whether the required assumption for proprietary estoppel includes an expectation of a particular legal relationship and irrevocability' 'Whether it was reasonable for CTA to rely on the family relationship and assurances provided in lieu of a formal lease' 'Whether the finding that all appellants were bound by a proprietary estoppel was justified given findings on absence of authority, conclusion of formal agreement, and knowledge']

Ratio Decidendi

A proprietary estoppel may arise where a party is encouraged or permitted by property owners to assume, and does assume, they will be granted a long-term interest in premises, and acts to substantial detriment as a result; it is not necessary that the party assumed a legally binding relationship or formal contract would exist. Where family practices eschew formality, it is not unreasonable to rely on those arrangements, and it would be unconscionable for the property owners to deny the interest after the induced expenditure and reliance. The orders of the primary judge should be upheld as the prerequisites for equitable intervention were satisfied in the circumstances.
