Some of the opposition-ruled states have declared they will not implement the changes in the Citizenship Act. Kerala, Punjab, West Bengal and Chhattisgarh have claimed they will block implementation of the CAA in their states. Madhya Pradesh Chief Minister has also indicated that his government is against the law. Meanwhile, the Maharashtra government will take a decision on the implementation of the Citizenship Amendment Act only after the Supreme Court hears a bunch of petitions challenging the legislation.
