The Supreme Court on Thursday cancelled a sedition case against journalist Vinod Dua and said a 1962 order protects every journalist from such charges. Mukul Rohatgi, former Attorney General and Senior Advocate, Supreme Court, in an exclusive interview to NDTV, said: "This law must be repealed; it is a relic of British imperialism. In the last more than 40 years of my practice I have not seen frequent invocation of the law except in the last 5 or 7 years; it shows very disturbing trends. Overzealous police authorities are invoking these sections only to please their political masters".
