The Supreme Court (SC) said today that additions and deletions are part of the electoral roll revision exercise undertaken by the Election Commission of India (ECI) as SC resumed final hearing on a batch of 19 petitions challenging the Special Intensive Revision of electoral rolls in Bihar. A bench comprising Chief Justice Surya Kant and Justice Joymalya Bagchi has also said that the possibility of forgery cannot be a ground to reject Aadhaar alone, observing that even passports are processed through private agencies performing public duties.
