Article 14 is one of the cornerstones of the Constitution. It states, "The State shall not deny to any person equality before the law or the equal protection of the laws within the territory of India." ... The equal protection of law means the State will not frame laws or rules that discriminate between two persons
The Citizenship Amendment Bill is being opposed by Opposition parties and many civil rights activists on the ground that it discriminates against Muslims. They say that such discrimination is unconstitutional under Article 14.
Rights under Article 14 are absolute. These two fundamental rights are not exclusive to the citizens of India but to "any person".
Article 14 is not confined to the citizens. It gives benefits of equality to any person within the territory of India even to a foreigner
