INTRODUCTION :
The ruling in Justice K.S. Puttaswamy (Retd.) v. Union of India (2017) addresses the constitutional legitimacy of the Aadhaar scheme and explores the extent of the right to privacy as outlined in Articles 14, 19, and 21 of the Constitution of India. The petitioner contested the compulsory collection, storage, and use of biometric and demographic data, arguing that it infringed on individual autonomy, dignity, and personal liberty. The Supreme Court, through a nine-judge Constitutional Bench, considered whether privacy is a fundamental right and clarified its scope and limitations regarding state objectives like welfare delivery, administrative efficiency, and national security. This case overturned earlier judgments that denied privacy as a fundamental right and established it as a key aspect of personal liberty in India.

DATE OF JUDGEMENT :
Delivered on: 24 August 2017
PARTIES INVOLVED :
Petitioner(s): Justice K.S. Puttaswamy (Retd.), challenging the Aadhaar scheme on constitutional grounds and alleging a violation of the fundamental right to privacy. Respondent(s): Union of India, defending the Aadhaar scheme by arguing that privacy is not explicitly guaranteed under the Constitution and that Aadhaar serves legitimate state interests.
FACTS OF THE CASE :-
The Aadhaar program was launched by the Union of India to assign residents a unique identity through the collection of biometric and demographic data, including fingerprints and iris scans.
Petitioners claimed that the mandatory collection, storage, and use of sensitive personal information infringes upon the right to privacy, which is essential to autonomy, dignity, and personal liberty—key elements protected under Article 21.
They argued that privacy is vital for personal autonomy, confidentiality of information, and protection against arbitrary state actions; therefore, any infringement must meet standards of legality, necessity, and proportionality.
Prior judgments denying privacy as a fundamental right—specifically M.P. Sharma v. Satish Chandra1and Kharak Singh v. State of U.P2.—were characterized as outdated and inconsistent with modern interpretations of Article 21 as seen in Maneka Gandhi v. Union of India³.
The State maintained that no specific provision guarantees privacy and asserted that Aadhaar is essential for welfare delivery, security measures, and administrative efficiency. Given these significant constitutional questions, the Supreme Court established a nine judge Constitutional Bench to consider whether privacy is indeed a fundamental right and to explore its scope and limitations.
ISSUES RAISED :-
Is the right to privacy guaranteed as a fundamental right under the Constitution of India? If recognized as such, what are its scope and permissible limitations according to constitutional law?
PETITIONER(S) ARGUMENTS :-
The petitioner argued that the right to privacy is an essential and intrinsic part of the Constitution, closely tied to the protection of life and personal liberty under Article 21. Privacy was described as a multi-faceted right, consisting of several legally significant components:
- Autonomy in personal decision-making – enabling individuals to make free choices regarding their bodies, families, reproductive matters, and intimate relationships without unlawful or arbitrary interference from the State.
- Confidentiality and protection of personal information – safeguarding individuals from unauthorized collection, storage, disclosure, or misuse of sensitive data by government authorities or third parties, thus preventing violations of personal autonomy and dignity.
- Freedom from unwarranted state surveillance – protecting citizens from intrusive monitoring, profiling, or tracking that could undermine civil liberties and compromise the foundational principles of a free and democratic society.
The petitioner also stressed that the right to privacy is woven into the constitutional “golden triangle” formed by Articles 14, 19, and 21, ensuring that equality, freedom of expression, and personal liberty are protected together, thereby reinforcing human dignity. It was argued that earlier judgments—M.P. Sharma v. Satish Chandra and Kharak Singh v. State of U.P.—which rejected privacy as a constitutional right were made in a historical context lacking contemporary technological insights, particularly with respect to digital data collection, mass surveillance, and modern informational infrastructure. Therefore, these judgments are no longer relevant in today’s India.
Drawing on the precedent set in Maneka Gandhi v. Union of India3, the petitioner contended that a purposeful and broad interpretation of Article 21 must include the right to control personal information, decisional autonomy, and intimate choices. This interpretation aligns with international human rights standards such as Article 12 of the Universal Declaration of Human Rights (UDHR, 1948)4and Article 17 of the International Covenant on Civil and Political Rights (ICCPR, 1966)5 which recognize privacy as a fundamental human right and emphasize states’ obligation to safeguard these rights domestically.
In conclusion, the petitioner maintained that any state action—such as implementing the Aadhaar program—must meet the three-part constitutional test of legality, necessity, and proportionality. This ensures that any infringement on privacy is narrowly defined, objectively justified, and strictly limited to achieving legitimate state objectives. Any excessive or arbitrary interference would violate constitutional guarantees and undermine the foundational principles of liberty and dignity enshrined in the Constitution
RESPONDENT’S ARGUMENTS:
The Union of India, acting as the Respondent, argued that the Constitution of India does not explicitly grant a standalone fundamental right to privacy. The Respondent highlighted that while privacy is relevant within a constitutional context, it is not absolute and must be weighed against significant state interests in governance, security, and public welfare.
The Respondent referenced binding precedents, notably M.P. Sharma v. Satish Chandra and Kharak Singh v. State of U.P., contending that these rulings consistently assert that the Constitution does not recognize privacy as an independent fundamental right. It was argued that these precedents should inform the Court’s approach to maintain judicial consistency and uphold stare decisis.
In support of the Aadhaar program, the Respondent presented several arguments:
- Legitimate Exercise of State Authority: Aadhaar represents a valid exercise of the State’s power under Articles 14, 19, and 21. The program addresses essential governmental objectives such as efficient delivery of welfare schemes, reduction of administrative leakages, and prevention of identity fraud.
- Administrative and Public Welfare Efficiency: By providing residents with a unique and verifiable identity, Aadhaar facilitates fair resource distribution, enhances transparency and accountability in governance, and reduces misuse of public funds. 3. National Security and Public Safety: The biometric and demographic identification framework supports efforts to prevent terrorism, financial crime, and other threats to public order, thereby promoting collective security and protecting societal interests. 4. Proportionality and Reasonableness of Interference: While acknowledging the importance of privacy, the Respondent argued that any intrusion by Aadhaar is lawful, necessary, and proportionate for achieving legitimate State objectives. The program is designed to minimize potential privacy intrusions while maximizing public benefit. 5. Balancing Individual Rights with Public Interest: The State asserted that the Aadhaar scheme effectively balances individual liberties with broader societal welfare. Any infringement on privacy is justified as minimal and objectively necessary for legitimate public interest.
The Respondent concluded that the Aadhaar program is constitutional
JUDGEMENT:
Unanimous Decision: Privacy is recognized as a fundamental right under Articles 14, 19, and 21. Prior decisions (M.P. Sharma; Kharak Singh) denying privacy as a fundamental right have been overruled.
LEGAL REASONING/ RATIO DECIDENDI:
Privacy is essential to life, liberty, and human dignity and necessitates state actions that are lawful, necessary, and proportionate.
It includes aspects of restfulness, personal space, and intimate decision-making—critical for individual autonomy in family life, marriage, and reproductive choices. In the digital age, informational privacy is crucial to protect citizens from unwarranted surveillance.
Comparative jurisprudence affirms privacy as a constitutional right in several jurisdictions (U.S., Canada, South Africa, Europe).
The Constitution functions as a living document that adapts to evolving socio-technological realities.The right to privacy is a fundamental right that serves as a cornerstone for liberty and dignity within the Constitution.
JUDICIAL AND POLICY OVERSIGHT:
It is essential to understand that any regulatory or governmental action must be subject to judicial review and ongoing policy oversight to prevent misuse, arbitrariness, or overreach. Courts and regulatory authorities act as checks and balances, ensuring that measures are transparent, accountable, and in compliance with constitutional and statutory standards. Oversight mechanisms are especially important in situations where policies could have far reaching effects, potentially impacting individuals, organizations, or sectors not directly intended. This oversight ensures that interventions remain focused, proportionate, and aligned with the public interest while protecting fundamental rights and established legal principles.
CONCLUSION:
This landmark judgment upholds privacy as a central constitutional value. It protects personal autonomy, reproductive rights, LGBTQ+ equality, and guards against arbitrary state intrusion.
This ruling aligns Indian jurisprudence with global human rights standards and positions India as a constitutionally aware democracy regarding privacy issues.
DIRECT QUOTE (CHANDRACHUD J.):
“The right to privacy is intrinsic to the right to life and personal liberty guaranteed under Article 21.”
Puttaswamy establishes that the Constitution is dynamic in its protection of individual freedom in the digital era.
