In Justice K.S. Puttaswamy (Retd.) v. Union of India, a nine-judge Bench of the Supreme Court unanimously recognised privacy as a fundamental right protected by the Constitution. The Court held that privacy forms an intrinsic part of life and personal liberty under Article 21 and the freedoms guaranteed by Part III. The judgment answered a constitutional reference arising from the Aadhaar litigation; it did not determine Aadhaar’s validity.

Background and Material Facts
The litigation arose from challenges to the Aadhaar scheme, under which the government collected demographic and biometric information for identification and access to specified services and benefits.
The petitioners questioned whether collecting and using this information infringed privacy. Before examining that claim, however, the Court faced a foundational question: did the Constitution protect privacy as a fundamental right?
Earlier judgments appeared to point in different directions. Decisions in M.P. Sharma v. Satish Chandra, 1954 SCR 1077, and Kharak Singh v. State of Uttar Pradesh, (1964) 1 SCR 332, contained observations denying constitutional protection to privacy.
Later decisions had recognised privacy interests in matters including surveillance, personal information and telephone interception.
Procedural History
On 11 August 2015, a three-judge Bench referred the constitutional question for consideration by a larger Bench.
The difficulty concerned judicial discipline: the earlier decisions involved eight and six judges, while subsequent privacy decisions had generally been delivered by smaller Benches.
On 18 July 2017, a five-judge Constitution Bench directed that the issue be placed before nine judges. That Bench delivered its decision on 24 August 2017.
Its task was to resolve privacy’s constitutional status, leaving the underlying Aadhaar challenges for separate adjudication.
Issues Before the Court
The principal questions were:
- Whether privacy is a fundamental right under the Constitution.
- Where that right is located within Part III.
- Whether the contrary observations in M.P. Sharma and Kharak Singh correctly stated the law.
- What broad principles govern the protection and restriction of privacy.
Arguments of the Parties
The petitioners argued that privacy was inseparable from dignity, autonomy and personal liberty. They submitted that the Constitution recognised this protection through several fundamental rights, even without expressly using the word “privacy”.
They also argued that the reasoning underlying the earlier decisions had been displaced by later constitutional developments, particularly R.C. Cooper v. Union of India, (1970) 1 SCC 248, and Maneka Gandhi v. Union of India, (1978) 1 SCC 248.
The Union relied on the earlier larger-Bench decisions and questioned whether every privacy interest could receive fundamental-right status. Arguments supporting its position also emphasised privacy’s uncertain boundaries and existing statutory protections.
Some State governments supported the petitioners, while others supported the Union or proposed intermediate positions.
Relevant Constitutional Provisions
Article 21 protects life and personal liberty. It supplied a central constitutional foundation for privacy.
Article 14 protects equality and guards against arbitrary State action. Article 19 protects specified freedoms whose meaningful exercise may require privacy, including expression and association.
The Preamble’s guarantees of liberty and dignity informed the interpretation of these provisions.
The Court also considered the significance of Article 20(3), which protects against compelled self-incrimination, when examining the scope of M.P. Sharma.

Court’s Reasoning
Privacy is inherent in liberty and dignity. The Court rejected the proposition that a right must be separately named in the constitutional text before it can receive protection.
Privacy enables individuals to make important personal choices and develop their personalities. Recognising it therefore involved interpreting existing constitutional guarantees, rather than adding a new constitutional provision.
Fundamental rights must be read together. The Court considered the development from A.K. Gopalan v. State of Madras, 1950 SCR 88, towards the interconnected understanding of rights reflected in R.C. Cooper and Maneka Gandhi.
Privacy could arise under different constitutional freedoms depending on the particular intrusion. It was not confined to one isolated provision.
Earlier precedents required correction. M.P. Sharma concerned search and seizure in the context of Article 20(3). Its observations could not support a general denial of constitutional privacy.
In Kharak Singh, the Court had protected aspects of personal liberty while also denying a guaranteed right to privacy. The nine-judge Bench rejected that denial.
Privacy extends beyond secrecy or the home. The opinions discussed bodily integrity, personal relationships, intimate choices and control over personal information. Privacy attaches to individuals; entering a public place does not automatically surrender every privacy interest.
The judgment also rejected the idea that privacy is a concern reserved for economically privileged people.
Privacy is subject to justified restrictions. Justice Chandrachud’s opinion for four judges identified three requirements for an intrusion into life or personal liberty: a legal basis, a legitimate State aim and proportionality.
Proportionality requires examination of the relationship between the objective and the interference used to achieve it. The existence of a law does not, by itself, establish constitutional validity.
Information creates particular privacy risks. The Court recognised that threats could arise from both government and private entities. It emphasised the need for a robust data-protection framework while leaving its detailed design to the appropriate policymaking process.

Separate Concurring Opinions
The judges agreed on privacy’s fundamental-right status, but their explanations and formulations were not identical.
| Opinion | Particular emphasis |
|---|---|
| Justice Chandrachud, for Chief Justice Khehar, Justices Agrawal, Nazeer and himself | Privacy’s relationship with dignity, interconnected rights, informational privacy and justified restrictions through legality, legitimate aim and proportionality. |
| Justice Chelameswar | Protection against intrusive observation and interference with intimate choices; the appropriate intensity of scrutiny depends on the privacy claim. |
| Justice Bobde | Privacy enables the exercise of constitutional freedoms; an interference must satisfy the standards applicable to the rights affected. |
| Justice Nariman | Privacy as an inalienable right recognised across Part III, with its application developing through individual cases. |
| Justice Sapre | The Preamble’s liberty, fraternity and dignity guarantees, together with the limited scope of the reference. |
| Justice Kaul | Informational autonomy, technological intrusions, protection against State and private interference, and safeguards against abuse. |
These differences matter when identifying the reasoning supporting a particular proposition, especially the standards governing restrictions.
Decision and Final Directions
The common order declared that:
- Privacy is protected under Article 21 and the freedoms guaranteed by Part III.
- M.P. Sharma stood overruled insofar as it denied constitutional protection to privacy.
- Kharak Singh stood overruled to the same extent.
- Subsequent decisions recognising constitutional privacy stated the correct legal position.
The reference was answered accordingly. The Court did not invalidate Aadhaar, award compensation or determine every possible privacy claim through this decision.
The merits of the Aadhaar challenge were addressed in a separate judgment delivered on 26 September 2018.
Ratio Decidendi
The central binding principle is that privacy is a constitutionally protected fundamental right, intrinsic to life, personal liberty and the freedoms guaranteed by Part III.
The contrary propositions in the earlier decisions could no longer govern constitutional interpretation.
The judgment does not make every collection of information unlawful or establish an unrestricted power to withhold information. Specific claims require examination of the interest affected, the legal basis for interference and the applicable constitutional standards.
Its discussion of possible privacy interests should also be distinguished from an order granting a particular remedy in an individual dispute.
Significance for Law Students and Legal Practice
As a matter of analysis, the case is useful for understanding implied rights, constitutional interpretation, larger-Bench precedent and the relationship between dignity and autonomy.
For research and legal practice, it provides a constitutional starting point for examining surveillance, bodily integrity and personal-data use. A complete legal argument must then connect that foundation to the facts, applicable legislation and subsequent judgments.
Key Takeaways
- Nine judges unanimously recognised privacy as a fundamental right.
- Privacy arises from Article 21 and other freedoms within Part III.
- The Court overruled earlier propositions denying constitutional privacy.
- Restrictions require constitutional justification; privacy is not absolute.
- The 2017 privacy reference and the later Aadhaar merits judgment are separate decisions.
