The relation of attorney and client is one of trust and confidence of the highest order. It is highly fiduciary in nature and demands utmost fidelity and good faith.
…A lawyer becomes familiar with all the facts connected with his client’s case. He learns from his client the weak points of the action as well as the strong ones. Such knowledge must be considered sacred and guarded with care. No opportunity must be given him to take advantage of the client’s secrets.
The rule is a rigid one designed not alone to prevent the dishonest practitioner from fraudulent conduct as well as preclude the honest practitioner from putting himself in a position where he may be required to choose between conflicting duties, and to protect him from unfounded suspicion of professional misconduct. The question is not necessarily one of the rights of the parties but adherence to proper professional standards. An attorney should not only keep inviolate his client’s confidence but should likewise avoid the appearance of treachery and double-dealing. (PCGG vs. SB, et al., supra.).
