attorney-client privilege

confidential communications between client and attorney, are not to be revealed at any time. The privilege, indeed, is not that of the attorney, but of the client; and it is indispensable for the purposes of private justice. Whatever facts, therefore, are communicated by a client to counsel, solely on account of that relation, such counsel are not at liberty, even if they wish, to disclose; and the law holds their testimony incompetent.
