A PIL has been filed in Calcutta High Court, seeking the implementation of NRC in Bengal and the issuance of national identity cards to distinguish Indian citizens from alleged illegal Bangladeshi immigrants, particularly in 10 border districts. The petition, filed by Paramita Dey, cites the NRC exercise in Assam conducted under Supreme Court supervision in 2014. A division bench of justices Sujoy Paul and Smita Das De is likely to hear the matter on July 29. The bench has asked the state to clarify whether any similar PIL has been filed.
