With about 700 million people across the country being eligible to vote in the just-concluded parliamentary elections, the process of the vote is indeed quite complex - in some sense, it is the pinnacle of organization, with almost every eventuality being considered. One such eventuality is the possibility of 'last metre influence'; therefore, political parties are not allowed to have their voter helpdesks, or any posters, handbills or any other promotional material within the specified distance from a polling booth.
Yet, there seems to have been some gaps. Although the Election Commission of India was clear that the sanitized zone extended up to 200m, the Tamil Nadu Government was still advising the police about a 100m zone!
