The Attorney General had earlier referred to the fact that as on August 21, over 90 crore citizens had been issued Aadhaar cards by the Unique Identification Authority of India (UIDAI).
Rohtagi had also said that since the apex court had stated Aadhaar card was not mandatory, there should not be any problem in allowing it to be used on voluntarily basis to establish the identity of persons and make available the benefits of other welfare schemes as well.
Earlier, the Supreme Court, while terming Aadhaar as optional, had barred the authorities from sharing personal biometric data collected for enrollment under the scheme.
It had also passed a slew of directions for the Centre till the matter was finally decided by a larger bench.
UIDAI, established by UPA-2 in 2009, issues Aadhaar cards to the citizens.
Under the programme, every citizen is to be provided with a 12-digit unique identification number for which biometric information is collected.
