With the absolute majority that it had secured in the Lok Sabha in the general elections of that year and with support drummed up in the Rajya Sabha, government passed the Citizenship Amendment Act (CAA) on 11th December, 2019 which read together with a controversial clutch of laws, sought to redefine Indian citizenship in the context of religious denomination.
Under this law the definition of illegal immigrant in the principal Act of 1955 stands amended for Hindu, Sikh, Parsi, Buddhist and Christian immigrants from Pakistan, Afghanistan and Bangladesh, “who entered into India on or before the 31st day of December, 2014” and who have lived in India without documentation. They will be granted fast-track Indian citizenship in six years. 12 years of residence had thus far been the standard eligibility requirement for naturalisation.
