RIGHT NOT to VOTE ANYONE - 49O

Do you know that there is a system in Indian constitution, as per the 1969 Act, in section "49-O". According to this section, a person can go to the polling booth, confirm his identity, get his finger marked and convey the presiding election officer that he does not want to vote anyone!
Yes, such a feature is available, but for obvious reasons our politicians have never disclosed it. This is called the "49O".
Why should you go and say "I VOTE NOBODY". Because in a ward, if a candidate wins, say by X votes, and that particular ward has received 49O votes more than that of X votes, then that polling will be cancelled and will have to be re-polled. Not only that, but the candidature of the contestants will be removed and they cannot contest the repolling, since people had already expressed their decision on them. This would bring fear into the parties and hence look for genuine candidates for their parties for election. This would change the way, of our whole political system. It is surprising why the Election Commission has not revealed such a feature to the public.
