"... the trustee really has no problem in establishing a fiduciary relationship. In my view where, as here (due to the effect of the doctrine of relation back), A pays B's money to C, B retains the beneficial title to the money and C becomes a bare trustee (see Chase Manhattan Bank v. Israel-British Bank[1981] 1 Ch. 105 , 119."
"It is clear from the authorities that the relation back of the trustee's title did not merely make the title of the debtor himself or any person claiming through the debtor defeasible in the event of adjudication. If the debtor was adjudicated bankrupt, then as from the date of the act of bankruptcy neither the debtor nor any such person claiming under him who could not bring himself within the protective provisions of the Bankruptcy Acts had any title at all; as from that date title was vested in the trustee. The position of the debtor and persons who claimed under him during the intermediate period was extremely curious. They did not possess a defeasible title, but either an indefeasible title if the act of bankruptcy was not followed by adjudication or no title at all if it was. Outside the law of bankruptcy no similar ambulatory title was known to the law."
"If this be correct the position is exactly the same as if the bankrupt had been in possession of goods belonging to another person, to which he had no title, and had sold them to the original transferee who had then resold them. In such a case neither the original nor any of the subsequent transferees would take any title at all, and the true owner could recover the goods from anyone in whose possession he found them. I know of no doctrine of law or equity which would relieve any of the transferees in these circumstances. It was however argued that this statement of Lord Esher cannot be taken to its full extent and that it must be confined to avoiding dealings with his property by the bankrupt himself after the date of relation back. This was founded on the argument that the original transfer was not void but only voidable, and that therefore any bona fide purchase from the original transferee was protected. I am not sure that void and voidable are quite apt expressions, but clearly the transfer was not void at the moment it was made, for it might be that no circumstances would ever arise in which a trustee's title would accrue or the bankruptcy law apply. I will assume that voidable is a correct expression to describe the nature of the transaction, and then it becomes necessary to ascertain the effect of the avoidance caused by the making of the receiving order. This seems to me to be quite different from the effect of avoidance in the ordinary case of a voidable transfer where no principles of bankruptcy law apply. In this latter case the title of the person avoiding the transaction arises only from the time when he elects to avoid, and therefore intervening bona fide transactions are protected because the transferor up to the date of avoidance had and could confer a good title. In the case under consideration so soon as the receiving order is made the trustee at once gets a title which relates back to the earliest act of bankruptcy within three months of the receiving order, whether it be the one upon which the receiving order is made or not, and therefore his position and rights are entirely different from those of an ordinary person who elects to avoid a voidable transaction."
"This seems to me to have no application to such a case as the present in which the effect of the subsequent bankruptcy is, without more, to vest the property in the trustee as from a date anterior to the dealing impeached. ... The statutory transfer passes the legal property in the goods to the trustee as from the commencement of the bankruptcy, and subsequent sales thereof by any person other than the trustee can confer no property on the purchaser ..."
"This could not be clearer. The transfer to the company constituted an act of bankruptcy. Had no adjudication followed, the transfer would have passed title to the company. It might still have been possible for the creditors to impugn it as a fraudulent conveyance, but then it could not have been avoided as against a bona fide purchaser for value without notice. The relation back of the trustee's title, however, did not strictly render the transaction either void or voidable; it operated automatically to divest the debtor at the date of the act of bankruptcy of any title to pass to the transferee, and this enabled the trustee to prevail against anyone who could not bring himself within the protective provisions of section 45."
"... trace their property at common law in that chose in action, or in any part of it, into its product, i.e. cash drawn by Cass from their client account at the bank."
"The product of or substitute for the original thing still follows the nature of the thing itself as long as it can be ascertained to be such and the right only ceases when the means of ascertainment fails, which is the case when the subject is turned into money and confined within the general mass of the same description."
"If this be correct the position is exactly the same as if the bankrupt had been in possession of goods belonging to another person, to which he had no title, and had sold them to the original transferee who had then resold them. In such a case neither the original nor any of the subsequent transferees would take any title at all, and the true owner could recover the goods from anyone in whose possession he found them. I know of no doctrine of law or equity which would relieve any of the transferees in these circumstances."
"Of course, `tracing' or `following' property into its product involves a decision by the owner of the original property to assert his title to the product in place of his original property."
"This is a liberal action in the nature of a bill in equity; and if, under the circumstances of the case, it appears that the defendant cannot in conscience retain what is the subject matter of it, the plaintiff may well support this action."
