The Parliament has passed the Citizenship Amendment Act, 2019 (CAA) on 11th December, 2019. In the amendment, persons belonging to minority communities of Hindus, Jains, Sikhs, Christians, Buddhists and Parsis from Afghanistan, Pakistan and Bangladesh, who have entered into India on or before 31st December 2014 have been excluded from the definition of “illegal immigrants”. There has been huge influx of migrants from across the border in India due to the religious persecution of the minorities being carried out since the time of Independence of India. The CAA is enacted by the government in order to exempt such illegal migrants who have been persecuted on the basis of religion and to provide a mechanism in order to enable them to apply for Citizenship by naturalisation by relaxing certain requirements. In Assam, the amendment has started a lot of violent protests as it is in conflict with the Assam Accord of 1985, which asks for identification and deportation of illegal immigrants who have come to Assam from Bangladesh, in order to protect their culture and tradition. Several petitions have been filed in the Supreme Court challenging the constitutional validity of the Citizenship (Amendment) Act, 2019. There has been debate going on in the country regarding the constitutionality of this amendment and many sections of the society is in a constant fear of this Act. Therefore the researcher through this research paper has analysed whether it’s constitutional or whether its goes against the principle of Secularism and how it will violate Assam Accord
