Chief Election Commissioner

The heads the Election Commission of India a body constitutionally empowered to conduct free and fair elections to the national and state legislatures. The President of India appoints the Chief Election Commissioner and two Election Commissioners. They have tenure of six years, or up to the age of 65 years, whichever is earlier. They enjoy the same official status and receive salary and perks as available to Judges of the Supreme Court of India.
The Chief Election Commissioner can be removed from office only through impeachment by ParliamentDespite 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 (something whose importance became very evident during US presidential election in 2000). 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 the fact that the Office of the Chief Election Commissioner had successfully implemented this across the entire diverse Indian population that also consisted of the rural illiterate people.

While the office has always been an important one in the machinery of the Indian political process, it gained significant public attention during the tenure of T.N. Seshan, from 1990-1996. Mr. Seshan is widely credited with undertaking a zealous effort to end corruption and manipulation in Indian elections. Though he made significant progress, several politicians attempted to derail these efforts. In particular, the expansion of the Election Commission to include the two Election Commissioners (in addition to the Chief Commissioner) was seen as a move to curtail the commission's ability to act aggressively.

The Election Commission enjoys complete autonomy and is insulated from any kind of executive interference. The body also functions as a quasi-judiciary body in matters of electoral disputes and other matters involving the conduct of elections. Its recommendations and opinions are binding on the President of India. However, the decisions of the body are liable for independent judiciary reviews by courts acting on electoral petitions.
