If even a quarter of these people are unable to prove they have the paperwork to qualify as a citizen, the travails of the 1.9 million Assamese, including more than one million Hindus left off the register, will seem like a rounding error by comparison. On Friday evening, the Home Ministry put out a series of tweets clarifying the situation: “Indian citizens do not have to prove any ancestry by presenting documents like identity cards, birth certificates etc of parents/grand parents dating back to pre-1971 situation.” It also said that people who were illiterate could be vouched for by members of their community. These are important qualifications but the process itself will still entail every Indian citizen having to prove they are citizens in one way or another. Devy speaks of the large number of undocumented Gurkhas living for generations in India and the flow of people between Nepal and Uttar Pradesh to the extent that the Nepalese rupee could be cashed in Uttar Pradesh. Then there are the large number of Tibetan refugees living in and around settlements in Karnataka and in Himachal Pradesh, living there since the Dalai Lama escaped to India in 1959. Their documents are typically in the name of camps rather than individuals. Given the large number of tribals in this country and the lack of personal documents carried by many people in rural India where “the poorest, least legally empowered people will be the first category” to be affected, those unable to provide documentary evidence and even those who can will be subject to “multiple confusions” as they work through the bureaucratic quagmire, says Devy, who has worked with tribal communities for three decades.
