“It will be a question of fact as to whether a solicitor is jointly acting for two parties. However, it is necessary to distinguish a joint retainer from three other situations where joint privilege will not arise.”
“Joint privilege can also arise where even though party A and party B have not jointly retained a lawyer (and only one of them is party to the relevant lawyer-client relationship), they have a joint interest in the subject matter of the communication. The defining characteristic of this aspect of joint privilege is that the joint interest must exist at the time that the communication comes into existence. So joint privilege will only arise in respect of a document created during the period when the joint interest subsists; in other words, the documents must have come into being for the furtherance of the joint purpose or interest.”
“If a joint interest exists then the same principles as those set out above in relation to joint retainers will apply. Accordingly, neither party can assert privilege as against the other in respect of communications coming into existence at the time the joint interest subsisted; hence, each party to the relationship can obtain disclosure of the other’s (otherwise privileged) documents so far as they concern the joint purpose or interest. However, both parties are entitled to maintain privilege as against the rest of the world. As with a joint retainer, the privilege is not lost simply because the parties subsequently fall out.”
“Examples of joint interests,” and it is in these terms: “Whilst not a rigidly defined concept, common examples of where such a joint interest might arise are between: a trustee and beneficiary; a parent company and its wholly-owned subsidiary; a company and its shareholders; a company and its director, and partners.” a trustee and beneficiary; a parent company and its wholly-owned subsidiary; a company and its shareholders; a company and its director, and partners.”
“Insufficient joint interests or a divergence of joint interests.”
“In so doing he was recognising the effect of a line of cases which have established that advice sought or given for the purpose of effecting iniquity is not privileged.”
“The starting point is the correspondence will only be protected by without prejudice privilege if it is written for the purpose of a genuine attempt to compromise a dispute between the parties. It is not a precondition that the correspondence bears the heading: “without prejudice.”
“It is undoubtedly a highly case sensitive question, or put another way, the dividing line may not always be clear. The various judicial pronouncements in the leading cases to which I have referred do not provide any precise pointers, and there are seemingly no other authorities directly in point.”
