Activists Harsh Mander, Aruna Roy, Nikhil Dey, historian Irfan Habib, economist Prabhat Patnaik and some organisations on Monday approached the Supreme Court challenging the constitutional validity of Citizenship (Amendment) Act, 2019 and sought direction to strike it down. The plea filed through advocate Prashant Bhushan sought direction to declare the Act as unconstitutional and illegal.

"These notifications and the Amendment Act are unconstitutional as they are discriminatory and violate the right to equality of all persons under the constitutional scheme. They are discriminatory towards illegal migrants from other countries in the neighbourhood of India apart from the three countries as well as discriminatory towards other minority communities such as Muslims, Jews, Ahmadiyas or Atheists who do not identify with a religious group," the plea said.
