K.S. Puttaswamy Case (2017) – Right to Privacy

The right to privacy was declared a fundamental right by the Supreme Court in K.S. Puttaswamy v. Union of India (2017), popularly known as the Right to Privacy case, settling a question that had divided Indian courts for decades. The judgment held that privacy is an intrinsic part of the right to life and personal liberty guaranteed by Article 21, and also flows from the freedoms protected under Part III of the Constitution more broadly.

What the Case Decided

In K.S. Puttaswamy v. Union of India (2017), the Supreme Court ruled that the right to privacy is protected as an intrinsic part of the right to life and personal liberty under Article 21, and as part of the wider freedoms guaranteed by Part III. The Court reasoned that privacy safeguards individual autonomy — the ability of a person to control vital aspects of their own life — and that without privacy, the exercise of other constitutional freedoms would itself be compromised.

Privacy Is Not Absolute

Crucially, the Court did not treat privacy as an unqualified right. It held that, like other fundamental freedoms under Part III, the right to privacy is subject to reasonable restrictions. Any law that encroaches upon privacy must withstand the same tests of permissible restriction that apply to other fundamental freedoms. In the specific context of Article 21, an invasion of privacy must be justified by a law that itself follows a procedure which is fair, just and reasonable — the same standard the Court had earlier applied to any deprivation of life or personal liberty.

The Three-Fold Test

The judgment laid down a structured test for evaluating any state action that encroaches on life, personal liberty, or privacy under Article 21. Such an invasion must satisfy three requirements together:

This legality–need–proportionality framework has since become the standard test applied whenever a law or state action is challenged as an unjustified invasion of privacy or personal liberty.

Overruling Earlier Precedent

The Puttaswamy judgment explicitly overruled two earlier Supreme Court decisions — the M.P. Sharma case (1954) and the Kharak Singh case (1962) — in both of which the Court had held that the right to privacy was not protected by the Constitution. The 2017 judgment also clarified that later decisions which had, in the interim, recognised a fundamental right to privacy despite Kharak Singh were correctly decided, resolving decades of inconsistency in how courts had approached the question.

Why This Case Matters

By locating privacy within Article 21, the Court placed it in the same interpretive tradition as other rights read into the guarantee of life and personal liberty — dignity, livelihood, shelter, health, and a clean environment among them. The judgment reflects the broader post-Maneka Gandhi understanding that "life" under Article 21 is not confined to mere physical existence but includes everything that makes a life meaningful and autonomous. Because the ruling came from a large constitutional bench of the Supreme Court, it carries strong precedential weight and has since shaped how the Court evaluates state surveillance, data collection, and other measures that touch personal autonomy.
