Pakistan Legal Practitioners and Bar Councils Rules, 1976 — section 172

172. No client, corporate or individual, however powerful, nor any cause civil or political, however important, is entitled to receive, nor should any advocate render, any service or advice involving disloyalty to the law whose ministers advocates are, or disrespect the judicial office, which they are bound to uphold, or corruption of any person or persons exercising a public office or private trust, nor indulge in deception or betrayal of the public. When rendering any such improper service or advice the advocate invites and merits stern and just condemnation. Correspondingly, he advances the honour of his profession and the best interest of his client when he renders service or gives advice tending to impress upon the client and his undertaking exact compliance with the strictest principles of moral law. He must also observe and advise his client to observe the statute law; though until a statute shall have been finally construed and interpreted by competent adjudication, he is free and indeed is entitled to advise as to its validity and as to what he conscientiously believes to be its just meaning and extent. But above all, an advocate will find his highest honour in a deserved reputation for fidelity to private trust and to public duty as an honest man and or a patriotic and loyal citizen.
