It is the duty of an attorney and counselor:

First. To maintain, while in the presence of the courts of justice, or in the presence of judicial officers engaged in the discharge of judicial duties, the respect due to the said courts and judicial officers, and at all times to obey all lawful orders and writs of the court.

Second. To counsel and maintain no actions, proceedings or defenses, except those which appear to him legal and just, except the defense of a person charged with a public offense.

Third. To employ for the purpose of maintaining the causes confided to him such means only as are consistent with truth, and never to seek to mislead the judges by any artifice or false statements of facts or law.

Fourth. To maintain inviolate the confidence, and, at any peril to himself, to preserve the secrets of his client.

Fifth. To abstain from all offensive personalities, and to advance no fact prejudicial to the honor or reputation of a party or witness unless required by the justice of the cause with which he is charged.

Sixth. Not to encourage either the commencement or continuance of an action or proceeding from motive of passion or interest.

Seventh. Never to reject for any consideration personal to himself the cause of the defenseless or the oppressed.
