“jurisdiction by which a court of equity, proceeding on the ground of fraud, converts the party who has committed it into a trustee for the party who is injured by that fraud.”
“The argument for a resulting trust was said to be supported by the case of a thief who steals a bag of coins. At law those coins remain traceable only so long as they are kept separate: as soon as they are mixed with other coins or paid into a mixed bank account they cease to be traceable at law. Can it really be the case, it is asked, that in such circumstances the thief cannot be required to disgorge the property which, in equity, represents the stolen coins? Moneys can only be traced in equity if there has at some stage been a breach of fiduciary duty, i.e. if either before the theft there was an equitable proprietary interest (eg. the coins were stolen trust moneys) or such interest arises under a resulting trust at the time of the theft or the mixing of the moneys. Therefore, it is said, a resulting trust must arise either at the time of the theft or when the moneys are subsequently mixed. Unless this is the law, there will be no right to recover the assets representing the stolen moneys once the moneys have become mixed. I agree that the stolen moneys are traceable in equity. But the proprietary interest which equity is enforcing in such circumstances arises – under a constructive, not a resulting, trust.”
