Justice K.S.Puttaswamy(Retd)& Anr vs Union Of India & Ors

The Supreme Court addressed the constitutionality of the Aadhaar Card Scheme, focusing on the right to privacy as implied under Article 21 of the Constitution of India. The Court noted that while earlier judgments, such as M.P. Sharma v. Satish Chandra and Kharak Singh v. State of U.P., cast doubt on the existence of a fundamental right to privacy, subsequent decisions have recognized its importance. The Court held that the right to privacy is indeed a fundamental right, thereby establishing a legal principle that privacy is protected under the Constitution, which has implications for the Aadhaar Scheme.
