39. It is well established that an advocate is a guardian of constitutional morality and justice equally with the Judge. He has an important duty as that of a Judge. He bears responsibility towards the society and is expected to act with utmost sincerity and commitment to the cause of justice. He has a duty to the court first. As an officer of the court, he owes allegiance to a higher cause and cannot indulge in consciously misstating the facts or for that matter conceal any material fact within his knowledge. In the case of harma & Ors. vs. High Court of Punjab & Haryana AIR 1957 SC 250 the Court noted that in all professional functions, an advocate should be diligent and his conduct should conform to the requirements of the law by which he plays a vital role in the preservation of society and justice system. As an officer of the court, he is under a higher obligation to uphold the rule of law and justice system.
