“82. I consider that this court is bound to hold that LPP does not apply, at common law, in relation to any professional other than a qualified lawyer: a solicitor or barrister, or an appropriately qualified foreign lawyer. That is the effect of Wilden Pump, and it is binding on us despite Lord Pannick's arguments, whether based on human rights or on an attempt to distinguish the case. 83.Even if we were not so bound, I would conclude that it is not open to the court to hold that LPP applies outside the legal profession, except as a result of relevant statutory provisions. It is of the essence of the rule that it should be clear and certain in its application, since it is not the subject of any ad hoc balancing exercise but is, to all intents and purposes, absolute. As applied to members of the legal professions, acting as such, it is sufficiently clear and certain. If it were to apply to members of other professions who give advice on points of law in the course of their professional activity, serious questions would arise as to its scope and application. To which accountants should it apply, given that "accountant" does not by itself denote membership of any particular professional body, or the obligation to comply with any, or any particular, professional obligations? To which other professional advisers would it apply? To what areas of the law would it apply as regards the advice of any adviser who is not a lawyer as such? These questions are serious and important, and would require a clear answer in order that the scope and application of the extended LPP should be known and understood.”
"The privilege is confined to the cases of counsel, solicitor, and attorney; but in order to raise the privilege, it must be proved that the information, which the adverse party wishes to learn, was communicated to the witness in one of those characters; for if he be employed merely as a steward, he may be examined."
