Court cases are painfully taxing to the litigants in India on all fronts, which is why Indians approach the courts only when all alternative avenues are already shut. Furthermore, a vast majority of Indian litigants are not rich people fighting to gain commerical advantage, but poor people making an effort to hold on to whatever little they have in the name of property and personal dignity. This makes the role of lawyers in India very crucial and rather critical.
A lawyer is not just accountable to his or her clients but also to the court, the legal system and the public at large because in making a case for his client he also makes a case for justice by lawful means. Therefore, the conduct of a lawyer must be above board at all times. No matter where he or she is, and no matter what he or she is doing, he is always looked upon as an officer of the court, a protector of the legal system and a crusader for justice.
That a lawyer must be ethical is beyond debate. The issue is whether we really need to enforce a code of conduct for the lawyers. Going by the number and kinds of complaints against the lawyers, the answer, sadly, seems to be 'yes'.
