Supreme Court in C. Ravichandran Iyer Vs. Justice A.M. Bhattacharjee and Others, :

21. Judicial office is essentially a public trust. Society is, therefore, entitled to expect that a Judge must be a man of high integrity, honesty and required to have moral vigour, ethical firmness and impervious to corrupt or venial influences. He is required to keep most exacting standards of propriety in judicial conduct. Any conduct which tends to undermine public confidence in the integrity and impartiality of the Court would be deleterious to the efficacy of judicial process. Society, therefore, expects higher standards of conduct and rectitude from a Judge. Unwritten Code of conduct is writ large for judicial officers to emulate and imbibe high moral or ethical standards expected of a higher judicial functionary, as wholesome standard of conduct which would generate public confidence, accord dignity to the judicial office and enhance public image, not only of the Judge but the Court itself. It is, therefore, a basic requirement that a Judge’s official and personal conduct be free from impropriety; the same must be in tune with the highest standard of propriety and probity. The standard of conduct is higher than that expected of a layman and also higher than that expected of an Advocate. In fact, even his private life must adhere to high standards of probity and propriety, higher than those deemed acceptable for others. Therefore, the Judge can ill-afford to seek shelter from the fallen standard in the society.
