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

The Supreme Court affirmed the right to privacy as a fundamental right under the Indian Constitution. The landmark ruling, made by a nine-judge bench, unanimously held that privacy is intrinsic to the right to life and personal liberty under Article 21 and is protected under the freedoms guaranteed by Part III of the Constitution. This judgement paved the way for greater scrutiny of government actions affecting privacy, including the Aadhaar scheme, and underscored the need for robust data protection laws in India.
