Consider the following statements regarding the Election Commission of India's (ECI) powers under Article 324 of the Constitution and the Representation of the People Act, 1950, with reference to the preparation and revision of electoral rolls:

Statements

1. The ECI's enquiry into citizenship for the purpose of determining eligibility for inclusion in the electoral roll is limited in scope, and any consequential action taken on that basis is confined to electoral consequences alone.
2. The Electors' Photo Identity Card (EPIC) is a primary document of citizenship that independently establishes a person's identity for all government purposes, including welfare entitlements.
3. Since the electoral roll is prepared on the basis of voter eligibility criteria, it is a valid proxy dataset for identifying beneficiaries of welfare schemes, as not every citizen needs to be a voter to receive state benefits.
