42 That sort of reasoning is applicable in this case. MFA appointed Westpac as its agent to receive cheques payable to MFA. Accordingly, the deposit of each cheque with Westpac was effective as receipt of the cheque by MFA. Upon the deposit of each cheque with Westpac, Westpac learned that the cheque was drawn by Burke on NIML's account. Ipso facto MFA learned that the cheque was drawn by Burke on NIML's account. As against NIML, MFA will not be heard to say that it did not thereby acquire knowledge of the details of the cheques.
43 The third rule leads to the same conclusion. It is based or at least based in part on the idea that there are occasions in which an agent may be an agent to know. It applies among other situations where an agent retains a principal because the principal expects that the agent's knowledge will be of benefit to the principal in connection with the transaction in view. Thus, for example, where an insured retains a broker, the insured generally expects that the broker will use the knowledge which the broker has acquired in the insurance market to obtain more favourable terms than the insured could secure for itself. In those circumstances the broker is an agent to know and thus the agent's knowledge will bind the principal. [49]
44 That sort of reasoning also applies in this case. If a customer retains a bank to receive cheques and to present them for collection, the customer expects that the bank will employ the knowledge which it has acquired in the course of its business as a bank to ensure so far as it reasonably can that the presentation and collection of the cheques is lawful and effective. In those circumstances I take it that the bank is an agent to know and therefore that the bank's knowledge is binding on the customer.
45 MFA argues to the contrary on several bases. The first is to say that MFA did nothing with the cheques because Westpac acted as an independent principal and not as an agent for MFA.
46 In my view that is not so. Westpac did not purport to deal with the cheques as a holder for value, but merely as MFA's agent for collection of the cheques; having no title to the proceeds.[50]
47 Secondly, MFA says that even if Westpac were its agent Westpac had no authority to collect cheques in circumstances which amounted to conversion of cheques and that MFA cannot be liable for acts of Westpac in breach of its authority.
48 In my view that submission is unconvincing. It is plain that Westpac had authority to collect cheques deposited for credit to the MFA Account and there is neither evidence nor anything else which implies that the authority was limited to the collection of cheques to which there was good title.
49 It was submitted for MFA that such a restriction should be implied as in effect going without saying, and that the fact that it has been held that a collecting bank may refuse to collect a cheque where collection would render it liable to suit for conversion [51] supported that notion.
50 I reject that submission too. So far from such a restriction going without saying, it seems to me that it would be fanciful to imply it. The most that the collecting bank can ever do is exercise due skill and care. Frequently, it is impossible for a collecting bank to ascertain with certainty in advance of collection that its customer has good title to a cheque. Section 95 of the Cheques Act 1986 exists to protect a collecting bank in just such circumstances. It recognises that no matter that a collecting bank may exercise due care there will be occasions when that it is not enough to guard against conversion. The fact that a bank may refuse to collect when it suspects the possibility of conversion in no way detracts from that conclusion. On the contrary, it strengthens the impression that an authority to collect is not restricted to cheques in respect of which there is no risk of conversion. There would be no need to consider whether there is a right in the bank to refuse to collect when there is risk of conversion if there were an implied term of its arrangement with its customer which prohibited it from collecting in those circumstances.
51 Thirdly, MFA contends that even allowing that Westpac was its agent, MFA had no control over the way in which Westpac exercised its authority and that there cannot be vicarious liability in the absence of control. As I understand that argument it is based on the idea that an employer or principal is not liable for the manner in which an employee or agent performs an act authorised to be undertaken unless the employer or principal has control over the manner of performance. Counsel for MFA made reference to a range of cases concerning the liability of employees and other principals for the negligence of servants and agents in the course of performance of duties.[52] He submitted that this case is analogous. As he would have it, MFA simply engaged Westpac to collect cheques and left it to Westpac as to how it would go about the task of collection.
52 In my view the argument is untenable. The principles of control, both in the ancient sense and in the sense in which the idea of control is now understood[53] have little to do with the liability of a defendant for tortious acts committed by the defendant's agents at the defendant's direction. A principal is liable for loss or injury caused by the tort of his agent if the wrongful act is specifically instigated, authorised or ratified by the principal;[54] and, by its contract with Westpac, MFA directed Westpac to collect the cheques on behalf of MFA and credit the proceeds of the cheques to MFA's account. At least, the tort of conversion was the necessary consequence of the contract.[55]
53 It was further submitted for MFA that any contract between MFA and Westpac was not specific enough to come within that rule. As counsel put it, it was not so much a case of MFA specifically instigating, authorising or ratifying the collection of any particular cheques - even less the instant cheques - as at most a general arrangement for the collection of such cheques as may be paid in for the credit to the MFA Account.
54 I reject that too. It is rudimentary that a principal may authorise an agent to act in a general way which is necessarily tortious, and the fact that the principal does not particularise the acts which are authorised will be irrelevant. Thus the oft cited example uttered by Parke, B. in Cobbett v Grey[56] of a principal who orders his agent to take into custody all persons who may come upon the principal's land. The principal would be liable in trespass to any one of those persons if improperly arrested. In this case it is the same. MFA authorised Westpac to collect such cheques as might be deposited for credit to its account and hence, in those circumstances, MFA would be liable for conversion of any of the cheques dealt with contrary to the rights to immediate possession of the true owner.
55 MFA contended that it cannot be vicariously liable for conversion of the cheques unless Westpac is liable for their conversion.
56 I also reject that contention. It is premised upon a misconception that MFA's liability is vicarious liability. As I see it the true nature of the liability is a direct liability as principal for loss or injury caused by the wrongful act of its agent.[57] In the particular circumstances of this case Westpac was but an instrument for the implementation of the will of MFA.[58] In those circumstances, all that need to be shown is that the acts of Westpac amounted to conversion of the cheques and that those acts were done at the specific instigation or with the specific authorisation of MFA in the sense that I have described it. Just as in the criminal law a principal in the first degree need not commit the crime with his own hands, but may do so through an innocent agent,[59] so too in the law of torts a principal may be liable for a tort committed by his agent even though the agent is protected from liability or is immune from suit.[60] As Atiyah puts it:
