(ii) the right of a client to the maintenance of all confidential information obtained by the solicitor during the course of the retainer, which right continues until the client expressly or impliedly consents to the discharge of the obligation of confidence;
(iii) that as a general rule it is necessary to identify and establish that there was some confidential information provided (see Bricheno v. Thorp (1833) 2. Cr. and M. 183[1833] EngR 139; , 149 E.R. 725.) But the degree of particularity of the confidential information must depend upon all the circumstances. Often it cannot be identified for fear of disclosure. In considering this factor it must be borne in mind that a solicitor makes notes, forms views and opinions of clients and observes things that the client may have forgotten or overlooked. In some cases the circumstances of the retainer and the nature of the legal work will be sufficient to establish the nature of the confidential information. In this regard the relationship between solicitor and client may be such that the solicitor learns a great deal about his client, his strengths, his weaknesses, his honesty or lack thereof, his reaction to crisis, pressure or tension, his attitude to litigation and settling cases and his tactics. These are factors which I would call the 'getting to know you' factors. The overall opinion formed by a solicitor of his client as a result of his contact may in the circumstances amount to confidential information that should not be disclosed or used against the client.
(iv) That a solicitor must, consistent with his retainer, act in the best interest of his client which means not only exercising skill but also putting at his client's disposal all relevant knowledge and if a solicitor is in a position where he is unable to reveal all his knowledge to a client he should not act for him. See Spector v. Ageda (1973) 1 Ch. 30 at p.48. This must be especially the position where the solicitor has acted for two clients in relation to one transaction and then thereafter acts for one against the other in relation to matters arising out of the same transaction."
