As an answer to any sweeping objection made to the profession in general, the view thus presented may be quite satisfactory. It by no means follows, however, as a principle of private action for the advocate, that all causes are to be taken by him indiscriminately and conducted with a view to one single end, _success_. It is much to be feared, however, that the prevailing tone of professional ethics leads practically to this result. He has an undoubted right to refuse a retainer, and decline to be concerned in any cause, at his discretion. It is a discretion to be wisely and justly exercised. When he has once embarked in a case, he cannot retire from it without the consent of his client or the approbation of the court.[10] To come before the court with a revelation of facts, damning to his client's case, as a ground for retiring from it, would be a plain breach of the confidence reposed in him, and the law would seal his lips.[11] How then is he to acquit himself? Lord Brougham, in his justly celebrated defence of the Queen, went to very extravagant lengths upon this subject; no doubt he was led by the excitement of so great an occasion to say what cool reflection and sober reason certainly never can approve. "An advocate," said he, "in the discharge of his duty knows but one person in all the world, and that person is his client. To save that client by all means and expedients, and at all hazards and costs to other persons, and among them to himself, is his first and only duty; and in performing this duty he must not regard the alarm, the torments, the destruction he may bring upon others. Separating the duty of a patriot from that of an advocate, he must go on reckless of consequences; though it should be his unhappy lot to involve his country in confusion." On the other hand, and as illustrative of the practical difficulty, which this question presented to a man, with as nice a perception of moral duty as perhaps ever lived, it is said by Bishop Burnet, of Sir Matthew Hale: "If he saw a cause was unjust, he for a great while would not meddle further in it, but to give his advice that _it was so_; if the parties after that would go on, they were to seek another counsellor, for he would assist none in acts of injustice; if he found the cause doubtful or weak in point of law, he always advised his clients to agree their business. Yet afterwards he abated much of the scrupulosity he had about causes that appeared at first unjust, upon this occasion; there were two causes brought him, which by the ignorance of the party or their attorney, were so ill-represented to him that they seemed to be very bad; but he inquiring more narrowly into them, found they were really very good and just; so after this he slackened much of his former strictness of refusing to meddle in causes upon the ill circumstances that appeared in them at first."[12]
