The case therefore comes to depend upon the drawing of the amount in the two cheques in favour of Murphy and Frith. This was a dealing by the younger defendant himself. It was not a dealing by Rees. He relied upon Rees as his clerk to inform him of the true ownership of the money and what he ought to do with it. Rees' deception of him was clearly a fraud committed as the firm's servant. It induced him to part with money which had been, as the plaintiffs intended it should be, reduced into the firm's effective control and exclusive control. There is a difficulty when an agent acting outside the scope of his authority or a servant outside the course of his employment pays the money of a stranger into a bank account in the name of his principal or master and then withdraws it under a general authority to sign cheques on the account which the principal or master has conferred upon him. As the money has been credited to the principal or master, it has been placed at least theoretically under his control and received on his behalf. But it is evident that in such a case the agent may from first to last retain the power of dealing with the money as he chooses. Though the bank account is in the name of his principal, the latter may have no effective means of controlling the money and excluding the agent. In Jacobs v. Morris[15] an attorney under power managing a branch office in London of a Melbourne merchant borrowed a sum of money, assuming to act under the power, but without actual or ostensible authority to do so. He paid it into a bank account upon which he had power to operate, an account in his principal's name. He then drew out the money and applied it to his private purposes. The principal was held not to be liable to the lender in an action of money had and received, chiefly on the ground that the lender had a full opportunity of acquainting himself with the fact that the loan was outside the power of attorney. But Farwell J. and, in the Court of Appeal, Stirling L.J. and, perhaps, Cozens-Hardy L.J. attached importance to the fact that the principal did not and could not know that the money was placed to the credit of the bank account in his name. Obviously it was at all times within the control of the attorney, and that control was in fact, though not in law, exclusive. Their Lordships placed some reliance on Marsh v. Keating[16], a partnership case in which a fraudulent partner forged powers of attorney for the transfer of stock which clients of the firm had placed under its control, and sold and transferred the stock, the proceeds of which were paid into the firm's bank account, whence he drew it for his own purposes. The innocent partners were held liable on the ground that, leaving aside the forgery, selling stock of clients and receiving the proceeds, by the course adopted, fell within the scope of the business and that the misappropriation of the money by the copartner afforded no answer, since the money had been received and the other partners might have known by the exercise of reasonable diligence that the money had been paid in. In delivering the opinion of the judges summoned to advise the House of Lords, Park J. said: "If they had not the actual knowledge, they had all the means of knowledge; and there is no principle of law upon which they can succeed in protecting themselves from responsibility, in a case wherein, if actual knowledge was necessary, they might have acquired it by using the ordinary diligence which their calling requires"[17]. The case is discussed by Lord Lindley in his Law of Partnership, 1st ed. (1860), pp. 244, 249; 5th ed. (1888), pp. 155, 160; 9th ed. (1924), pp. 223, 230, for the purpose of emphasizing the fact that "it was the business of the firm there to sell through their broker stock belonging to their customers and to receive and remit the proceeds: and the money for which the firm was held answerable did arise from the sale of the stock of a customer though it was sold under a forged power of attorney." Sir Frederick Pollock, in his Digest of the Law of Partnership, 7th ed. (1900), p. 47; 12th ed. (1930), p. 52, note m, makes the following remarks on Lord Lindley's comment: - "If his comment is right, as it clearly is, one can hardly see what the knowledge or means of knowledge of the partners had to do with it; they were liable because money representing their customer's property had come, in an apparently regular course, though in truth by wrong, into the custody of the firm. The point is treated as material in the opinion of the judges. The truth is that the rule ... by which the ordinary course of business is the primary test of the firm's liability was developed only by later decisions." In Jacobs v. Morris[18] Vaughan Williams L.J. said: "I am not sure that in Marsh v. Keating3(1834) 2 Cl. & Fin. 250; 6 E.R. 1149. either the House of Lords or the judges whose opinion was taken meant to decide either that ignorance and want of means of knowledge will exonerate a person through whose account a sum of money has passed from responsibility, or that knowledge of the fact is essential to liability."
