Kolkata: The Calcutta High Court has ruled that documents such as Aadhaar cards, PAN cards and voter identity cards are not conclusive proof of Indian citizenship. To establish Nasir's Indian citizenship, the petitioner relied on his voter ID card, Aadhaar card, PAN card issued by the Income Tax Department and a bank passbook. A division bench comprising Justices Debangsu Basak and Ajay Kumar Gupta held that voter identity cards, Aadhaar and PAN cards are not conclusive proof of Indian citizenship. It also ruled that merely holding a bank account cannot be treated as proof of Indian citizenship. Holding that Nasir's Indian citizenship had not been established, the court declined to interfere with the authorities' decision and dismissed the petition.
