It is true that it is the duty of a lawyer to defend his client. but there is a larger duty to uphold the truth. The problem is that the allegiance to client becomes so an overarching principle for lawyers that they go to any extent to distort facts and subvert justice. I have not read about what jethmalani has said about Jessica lal in the court but if he has said something not based on facts and has tried to malign the girl then Jethmalani will die an unhappy man.
