Yeoman’s Row Management v Cobbe [2008] UKHL 55
House of Lords
Basic Facts : C and D had an oral agreement for property redevelopment. D withdrew after planning permission, leading C to claim estoppel.
Issue for the Court : Is unconscionable behavior enough to found a claim of estoppel?
Held :The court ruled that proprietary estoppel could not be invoked where there was no clear or unequivocal promise that gave rise to an expectation of a property interest.
Lord Scott (allowing the appeal)
Proprietary estoppel requires a proprietary claim and conduct that makes it unconscionable to deny the claim.
Mere expectation is insufficient; a clear legal or equitable interest must be shown.
