Lawyers should expose without fear or favor before the proper tribunals corrupt or dishonest conduct in the profession, and should accept without hesitation employment against a member of the Bar who has wronged his client. The counsel upon the trial of a cause in which perjury has been committed owe it to the profession and to the public to bring the matter to the knowledge of the prosecuting authorities. The lawyer should aid in guarding the Bar against the admission to the profession of candidates unfit or unqualified because deficient in either moral character or education. He should strive at all times to uphold the honor and to maintain the dignity of the profession and to improve not only the law but the administration of justice.
