Equity in UK Law

But the proprietary interest which equity is enforcing in such circumstances arises under a constructive, not a resulting, trust. Although it is difficult to find clear authority for the proposition, when property is obtained by fraud equity imposes a constructive trust on the fraudulent recipient: the property is recoverable and traceable in equity.

We have to ask ourselves: What should we do now so as to ensure fair dealing between the parties? It is only cross-claims that arise out of the same transaction or are closely connected with it. And it is only cross-claims which go directly to impeach the plaintiff's demands, that is, so closely connected with his demands that it would be manifestly unjust to allow him to enforce payment without taking into account the cross-claim.

In the latter case, the transferor may elect whether to avoid or affirm the transaction and, until he elects to avoid it, there is no constructive (resulting) trust; in the former case, the constructive trust arises upon the moment of transfer.

Equity lawyers speak of a right of subrogation, or of an equity of subrogation, but this merely reflects the fact that it is not a remedy which the court has a general discretion to impose whenever it thinks it just to do so. The equity arises from the conduct of the parties on well-settled principles and in defined circumstances which make it unconscionable for the defendant to deny the proprietary interest claimed by the plaintiff.

In my view the authorities cited by Mr Gross and the broad principles set out in the above quotations support the submission that equity would have taken the view that it should apply the statute by analogy to a claim for damages or compensation for a dishonest breach of fiduciary duty.

The doctrine of locus poenitentiae therefore demonstrates that the effect of illegality is not to prevent a proprietary interest in equity from arising or to produce a forfeiture of such right: the effect is to render the equitable interest unenforceable in certain circumstances. The effect of illegality is not substantive but procedural.

Where there is a contract between A and B, and A makes an equitable but not a legal assignment of the benefit of that contract to C, this equitable assignment doesnot put C into a contractual relation with B; and, consequently, C is not in a position to exercise directly against B any right conferred by the contract upon A.
