Chief Election Commissioner of India is usually a member of the Indian Civil Service and mostly from the Indian Administrative Service . It is very difficult to remove the authority of the Chief Election Commissioner once appointed by the president, as two - thirds of the Lok Sabha and the Rajya Sabha need to vote against him for disorderly conduct or improper actions . </P> <P> Despite the recent changes in the hierarchy, the system always had powers to impose unambiguous rules and guidelines that applied across the entire nation e.g. as to how the ballots will be cast and counted, what will be regarded as' unqualified' vote . India was probably one of the first countries in the World to go for a completely electronic ballot in the last elections . What made this remarkable was that the Election Commission of India had successfully implemented this across the entire diverse Indian population that also consisted of the rural illiterate people . </P>
