Justice K. S. Puttaswamy v. Union of India, Supreme Court of India (2017)
Justice K. S. Puttaswamy (Retd.) v. Union of India ((2017) 10 SCC 1) is a landmark 9-judge constitutional decision that unanimously declared the Right to Privacy as an intrinsic, fundamental right protected under and Part III of the Indian Constitution. The ruling explicitly overruled prior historic precedents (M.P. Sharma 1954 and Kharak Singh 1962) that had held privacy was not a fundamental right.
91-year-old retired High Court Judge K. S. Puttaswamy filed a writ petition challenging the Union Government's mandatory scheme requiring citizens to obtain a 12-digit Aadhaar biometric identity card for accessing essential government benefits, subsidies, and banking services. The challenge alleged mass government surveillance, lack of data security, and systemic erosion of bodily and informational autonomy.
Fundamental Right to Privacy
Aadhaar Scheme notifications, biometric collection protocols, data leakage logs, foreign data protection framework reports, and jurisprudence from international human rights tribunals.
Petitioners argued that privacy is a core natural right linked to human dignity, individual autonomy, and bodily integrity under Articles 14, 19, and 21. The Union Government argued that the Constitution contains no explicit Right to Privacy and that socio-economic welfare distribution overrides abstract privacy rights.
A 9-judge bench unanimously held that Privacy is a fundamental right protected as an integral component of (Right to Life and Personal Liberty) and individual liberties under Part III.
The Court reasoned that privacy encompasses personal intimacy, bodily integrity, informational privacy, and decisional autonomy. Any state infringement on privacy must satisfy a strict three-fold test: (1) Legality (backed by statutory law), (2) Legitimate State Aim, and (3) (a rational connection between the means adopted and the goal sought).
Formally established Privacy as a fundamental constitutional right, established a strict standard for state surveillance/data collection, and paved the way for modern personal data protection legislation.

Is privacy a fundamental right?
India and the United States both have constitutional courts that have faced the question of privacy rights, but they approach it very differently. Puttaswamy (2017) recognized privacy as a fundamental right in India, while the U.S. has strong privacy jurisprudence.
U.S. has strong privacy jurisprudence. Why preferable to others: UK, France, China, and Russia have different traditions.
Each system arrived at the same problem from a different direction: how to protect privacy in the digital age. In India, the Court had to decide whether privacy was a fundamental right. In the U.S., courts have long recognized privacy rights.
| Topic | India | USA |
|---|---|---|
| Legal Issue | Is privacy a fundamental right? | How is privacy protected? |
| Constitutional Basis | Articles 14, 19, 21; privacy | Fourth Amendment; privacy cases |
| Leading Case | Puttaswamy (2017) | Griswold v. Connecticut (1965) |
| Court's Reasoning | Privacy is intrinsic to liberty and dignity | Privacy is protected under liberty |
| Outcome | Codified privacy as fundamental right | Established privacy jurisprudence |
Both systems recognize that privacy is an important value, and both courts have issued landmark rulings to protect privacy. In both countries, the judiciary has played a key role in advancing privacy rights.
The paths diverge in approach. In India, Puttaswamy codified privacy as a fundamental right emerging from Articles 14, 19, and 21, with a three-fold test for state interference. The Indian approach is explicit and constitutional. In the U.S., by contrast, courts have recognized privacy through various amendments and doctrines, with a more implicit approach. The U.S. approach is more decentralized, while the Indian approach is more unified. The result is a more explicit approach in India and a more implicit one in the U.S.
What follows from all this is that privacy is not just about technology—it is about rights. In India, the explicit approach provides clear protection. In the U.S., the implicit approach provides flexibility. For citizens, both systems provide privacy protections.
Puttaswamy and U.S. privacy cases both gave judges the power to define privacy, but they approached the problem differently. One codifies; the other implies. Together, they show that privacy is not just about data—it is about dignity.
