Asserting that Aadhaar is a unique identity project, its pioneer and Infosys co-founder Nandan Nilekani on Wednesday hailed the Supreme Court judgement on it as landmark.

"This is a landmark judgement in favour of Aadhaar, which is a unique identity project that is critical to the development goals of the nation," Nilekani tweeted hours after a five-judge constitutional bench of the apex court delivered a verdict in its favour. Nilekani was the first Chairman of Aadhaar's state-run Unique Identification Authority of India (UIDAI) from 2009 to 2014. He re-joined the global software major in August 2017 as non-executive Chairman.
