The RTI act in India is something that must not be tampered with. The idea of holding government employees accountable will go a long way in stemming corruption in India. Corruption in India is deeply inequitizing in my opinion. It allows the rich to get richer by bribing their way through.
Hope Dr. Singh listens. Putting arbitrary clauses against 'vexatious and frivolous complaints' in the law will present a massive loophole - and can also provide a shield for the guilty. The additional inconvenience caused by looking at frivolous requests will certainly not outweigh the societal costs of making corruption easier.
Dr. Singh is probably the most intellectual PM we have ever had. Would he want to go down in history as the person under whom (a) It was enacted AND (b) It was weakened?
