Requirememts to prove breach of confidence
A claim was made for breach of confidence in respect of technical information whose value was commercial.
Held: Megarry J set out three elements which will normally be required if, apart from contract, a case of breach of confidence is to succeed. In this case the information was found not to be of a confidential nature as it was already in the public domain. Megarry went on to say: ‘where information of commercial or industrial value is given on a business-like basis and with some avowed common object in mind, such as a joint venture . . I would regard the recipient as carrying a heavy burden if he seeks to repel a contention that he was bound by an obligation of confidence.’
‘First, the information must be of a confidential nature. As Lord Greene said in the Saltman case . . ‘something which is public property and public knowledge’ cannot per se provide any foundation for proceedings for breach of confidence. However confidential the circumstances of communication, there can be no breach of confidence in revealing to others something which is already common knowledge. But this must not be taken too far. Something that has been constructed solely from materials in the public domain may possess the necessary quality of confidentiality: for something new and confidential may have been brought into being by the application of the skill and ingenuity of the human brain . . Novelty depends on the thing itself, and not upon the quality of its constituent parts . . whether it is described as originality or novelty or ingenuity or otherwise, I think there must be some product of the human brain which suffices to confer a confidential nature upon the information.
The second requirement is that the information must have been communicated in circumstances importing an obligation of confidence. However secret and confidential the information, there can be no binding obligation of confidence if that information is blurted out in public or is communicated in other circumstances which negative any duty of holding it confidential. From the authorities cited to me, I have not been able to derive any very precise idea of what test is to be applied in determining whether the circumstances import an obligation of confidence. In the Argyll case . . Ungoed-Thomas, J. concluded his discussion of the circumstances in which the publication of marital communications should be restrained as being confidential by saying ‘If this was a well-developed jurisdiction doubtless there would be guides and tests to aid in exercising it’. In the absence of such guides or tests he then in effect concluded that part of the communications there in question would on any reasonable test emerge as confidential. It may be that that hard-worked creature, the reasonable man, may be pressed into service once more; for I do not see why he should not labour in equity as well as at law. It seems to me that if the circumstances are such that any reasonable man standing in the shoes of the recipient of the information would have realised that upon reasonable grounds the information was being given to him in confidence, then this should suffice to impose upon him the equitable obligation of confidence. In particular, where information of commercial or industrial value is given on a business-like basis and with some avowed common object in mind, such as a joint venture or the manufacture of articles by one party for the other, I would regard the recipient as carrying a heavy burden if he seeks to repel a contention that he was bound by an obligation of confidence: see the Saltman case . . On that footing, for reasons that will appear, I do not think I need explore this head further. I merely add that I doubt whether equity would intervene unless the circumstances are of sufficient gravity; equity ought not to be invoked merely to protect trivial tittle-tattle, however confidential.
Thirdly, there must be an unauthorised use of the information to the detriment of the person communicating it. Some of the statements of principle in the cases omit any mention of detriment; others include it. At first sight, it seems that detriment ought to be present if equity is to be induced to intervene; but I can conceive of cases where a plaintiff might have substantial motives for seeking the aid of equity and yet suffer nothing which could fairly be called detriment to him, as when the confidential information shows him in a favourable light but gravely injures some relation or friend of his whom he wishes to protect. The point does not arise for decision in this case, for detriment to the plaintiff plainly exists. I need therefore say no more than that although for the purposes of this case I have stated the proposition in the stricter form, I wish to keep open the possibility of the true proposition being that in the wider form.’
Megarry J said: ‘if the circumstances are such that any reasonable man standing in the shoes of the recipient of the information would have realised that upon reasonable grounds the information was being given to him in confidence, then this should suffice to impose on him the equitable obligation of confidence.’
