Any Indian citizen who is registered as a voter and is over 25 years of age is allowed to contest elections to the Lok Sabha or State Legislative Assemblies. For the Rajya Sabha the age limit is 30 years. Candidates for the Rajya Sabha and Vidhan Sabha should be a resident of the same state as the constituency from which they wish to contest.
Every candidate has to make a deposit of Rs.
The deposit is returned if the candidate receives more than one-sixth of the total number of valid votes polled in the constituency. Nominations must be supported at least by one registered elector of the constituency, in the case of a candidate sponsored by a registered Party and by ten registered electors from the constituency in the case of other candidates. Returning Officers, appointed by the Election Commission, are put in charge to receive nominations of candidates in each constituency, and oversee the formalities of the election. In a number of seats in the Lok Sabha and the Vidhan Sabha, the candidates can only be from either one of the scheduled castes or scheduled tribes. The number of these reserved seats is meant to be approximately in proportion to the number of people from scheduled castes or scheduled tribes in each state.
