The petitioners had alleged that collection of personal details like finger prints and iris scan violated the right to privacy.
Requesting an early hearing, the Centre on Wednesday had said, "Millions of people are involved in the outcome of the case".
Senior Advocate Shyam Divan and Attorney General for India KK Venugopal mentioned the matter today before Chief Justice JS Khehar.
The court also took note of the fact of the enactment of the Aadhaar Act giving the scheme a statutory status. All matters related to Aadhaar, including the right to privacy, will be presented before the bench during the two-day hearing. Recently, a statutory provision was upheld by the court making linking of Aadhaar with PAN mandatory.
It was argued that Aadhaar card is an invasion of privacy and a bad violation of basic human rights.
The apex court has chose to constitute a five-judge bench to hear whether there is a right to privacy or not. In a setback to the Arvind Kejriwal government, the Supreme Court had refused to stay the Delhi High Court's verdict declaring the LG the administrative head of Delhi. Recently, the Centre had termed Aadhaar a "transformational home-grown IT project". He explained that an 8 judge Bench of the SC had earlier ruled that right to privacy is not a fundamental right.
They contended that it violated the apex court's order of 2013 that no one can be denied benefits of any scheme due to absence of Aadhaar.
