In Public Finance Bhd, the Federal Court opined at p 381 as follows: “ At common law (in the special sense now of its being distinguished from rules in equity) contractual rights, eg as to debts, were not assignable, ie transferable to another person without the consent of both parties to the contract conferring such contractual rights. Equity stepped in and has long allowed such assignment of such debts to another person who is not privy to the contract in respect of such debts, without at all the consent of the debtor: see eg Brice v Bannister (1878) 3 QB 569; and even without notice to the debtor, see Kelly v Selwyn [1905] 2 Ch 117 and Ward v Duncombe [1893] AC 369. Such assignments as so allowed by equity are called `equitable assignments’. The validity of such equitable assignments is not affected by any failure to comply with requirements as laid down in s 4(3) of the Civil Law Act 1956, for an assignment that so complies has been described as a statutory assignment; being so statutory for such an assignment has the sole intended effect of facilitating an assignee to sue in his own name directly, irrespective of whether the chose in action is an equitable chose in action or a legal chose in action (not, be it noted, whether an assignment is equitable or statutory). By being a statutory assignment itself, the `statutoriness’ of such an assignment, ipso facto, does not prevail over an earlier equitable assignment, and this is so even with the added factor that the assignee involved in a statutory assignment took the assignment for value without notice of an earlier equitable assignment: eg see E Pfeiffer Weikellerei-Weinenkauf GmbH & Co v Arbuthnot Factors Ltd [1988] 1 WLR 150. We need to say a few words more about the great desirability of giving notice of assignment of a Page 17 of 24 debt by an assignee to the debtor, even though absence of such notice does not affect the validity of the equitable assignment as between the assignor and the assignee. If notice is not given, the assignee must give credit for any payment made to the assignor by the debtor. This rule means that, by extension, even if the assignor assigns once more the debt to another person in fraud or otherwise on the earlier assignee, and that other person gives notice to the debtor; and if the debtor pays that other person or the second assignee, then the earlier assignee must still give credit to the debtor for his payment thus, for the debtor cannot be blamed for doing lawfully in ignorance of the title of the earlier assignee who has failed to give notice of the assignment to the debtor. Notice to debtor is for the protection of the assignee himself. It is this effect of what the debtor does lawfully as described that dims the view of the true role of the nemo dat rule in the resolution of disputed claims to a same debt. The money paid to the `second assignee’ can, of course, be recovered by the earlier assignee on the nemo dat principle.” [Emphasis
