Chandrasekhar, who had intervened in the hearing held to decide whether right to privacy was a fundamental right, said the verdict was a first step towards evolving a new legal eco-system.
"It is clear that Aadhaar and all other legislations existing and proposed will have to meet the test of privacy being a fundamental right," he said in a statement.
The vice chairman of NDA in Kerala also said that the move not only accorded legal rights for digital consumers and citizens of the country, but also paved the way for amendments to legislations that have overlooked citizens' rights to privacy.
Chandrasekhar, a nominated member to the upper house of Parliament, had in 2013 filed a petition against Aadhaar in the top court challenging its weak architecture and the lack of protection for the data of the citizens of India.
"Both in Parliament and in my petition to the apex court, I have repeatedly stated privacy is a fundamental right with reasonable restrictions like most fundamental rights in our Constitution.
