Petitioner: Justice K.S Puttaswamy; former judge of Karnataka High Court 

Respondent: Union of India

Court:

Supreme Court of India

Citation:

(2017) 10 SCC 1

Facts

The case of K.S. Puttaswamy v. Union of India (2017) emerged from a judicial challenge to the Aadhaar plan, which was implemented by the Government of India to develop a unique identity system for residents. The Unique Identification Authority of India (UIDAI) established the plan, which required individuals to furnish biometrics (fingerprints and iris scans) and demographic information to get an Aadhaar number. The government made Aadhaar mandatory for accessing certain welfare benefits, financial transactions, and public services, raising concerns about potential misuse of personal data and invasion of privacy. Justice K.S. Puttaswamy (Retd.), a former Karnataka High Court judge, filed a Public Interest Litigation (PIL) in 2012 before the Supreme Court, claiming that Aadhaar infringed Indian people’s right to privacy. He contended that compelling people to disclose their personal and biometric data with the state was unlawful and constituted a risk of widespread monitoring. The petitioners claimed that the Constitution intrinsically safeguarded privacy as a basic right under Article 21 (Right to Life and Personal Liberty)[1] and other provisions. The Union of India supported Aadhaar, claiming that the Constitution does not specifically mention privacy as a basic right and that Aadhaar is required to ensure the transparency, efficiency, and targeted delivery of benefit packages. Given the serious constitutional issues raised, the case was referred to a 9-judge Constitution Bench of the Supreme Court to determine whether the right to privacy is a basic right under the Indian Constitution. This reference resulted in one of the most momentous decisions in Indian constitutional history.

Issue

Whether the right to privacy is a basic right guaranteed by the Indian Constitution, namely Article 21 (Right to Life and Personal Liberty) and Part III (basic Rights).

Legal Principles

Fundamental Rights Under Part III of the Indian Constitution

Article 21: Right to Life and Personal Liberty.

Article 21 states, “No person shall be deprived of his life or personal liberty except according to procedure established by law.” The Supreme Court has construed “life” and “liberty” broadly, including dignity, autonomy, and privacy. In Maneka Gandhi v. Union of India (1978), the Court determined that any restriction under Article 21 must be equitable, fair, and reasonable. In Puttaswamy, the Court elaborated on this idea, acknowledging privacy as an essential component of human liberty.

Article 14: Right to Equality

Article 14 ensures equality before the law and equal protection of the laws. It forbids arbitrary state acts and requires justice. The “arbitrariness test” guarantees that privacy rules are reasonable and not discriminatory[2]. In Puttaswamy, the Court stressed the need of avoiding arbitrary intrusions on privacy. The decision reiterated that state activities limiting privacy must have a legitimate goal, be required, and reasonable, and avoid discriminating or disproportionate government surveillance.

Articles 19 and 25 – Freedom of Expression and Religious Freedom

Article 19 provides free speech, expression, and association, while Article 25 protects religious freedom. Privacy protects these liberties by allowing people to think, express, and practice their beliefs without excessive government intrusion. In Puttaswamy, the Court emphasized that free expression and religious freedom necessitate a private space that protects persons from pressure or observation. The decision increased safeguards against government overreach, ensuring that privacy promotes free thought and personal convictions.

The doctrine of proportionality and reasonable restrictions:

The idea of proportionality assures that governmental measures restricting basic rights are necessary, appropriate, and least restrictive. Restrictions must have a genuine purpose and not be excessive. In Puttaswamy, the Court held that any violation of privacy must meet the proportionality test, which involves balancing individual rights with governmental objectives. This concept prohibits unjustified monitoring, data collecting, and privacy intrusions, requiring the state to justify any restrictions on human liberties through lawful, logical, and proportionate ways.

Arguments

Petitioner’s Arguments

1. Privacy: An Inherent and Fundamental Right

The petitioners contended that privacy is inextricably linked to human dignity, autonomy, and personal liberty, constituting an essential basic right. They argued that personal decisions, bodily integrity, and informational privacy are fundamental parts of life under Article 21. Individuals without privacy are unable to freely express themselves or enjoy their fundamental rights. The petitioners stressed that privacy is inextricably linked to other fundamental rights such as freedom of expression, religion, and personal decisions.

2. Aadhaar and the Risk of a Surveillance State

The petitioners expressed worry that the Aadhaar program facilitated widespread monitoring, infringing citizens’ right to privacy. By requiring biometric verification for access to social programs and financial services, the government might track people’ actions, thus creating a surveillance state. They said that without proper controls, Aadhaar data might be exploited, resulting in illegal profiling and privacy violations. The absence of data protection regulations at the time raised worries about identity theft, exclusion, and government overreach.

3. Overruling previous judgments and global standards

The petitioners claimed that previous Supreme Court decisions M.P. Sharma (1954) and Kharak Singh (1962)[3] wrongfully rejected privacy as a fundamental right. They asked the Court to align Indian jurisprudence with international norms, citing worldwide legal principles such as the Universal Declaration of Human Rights and the International Covenant on Civil and Political Rights, which regard privacy as a fundamental human right. They stressed that modern constitutional democracies value privacy as a fundamental civic liberty.

Respondent’s Arguments

1. The Constitution makes no explicit mention of privacy

The Union of India said that the right to privacy is not specifically stated as a basic right in the Indian Constitution. The government cited prior Supreme Court decisions in M.P. Sharma (1954) and Kharak Singh (1962), which determined that privacy was not constitutionally guaranteed. They argued that if the Constitution’s framers had intended to include privacy as a fundamental right, they would have explicitly stated so. Thus, privacy could only be recognized through legislative action rather than judicial interpretation.

2. Aadhaar and State Legitimate Interest

The government defended Aadhaar as a welfare-focused effort, claiming that the state had a legitimate interest in collecting biometric data to enable efficient subsidy delivery, combat fraud, and eliminate phony beneficiaries. They said that Aadhaar enabled millions of impoverished people to access critical social programs including food rations and direct benefit payments. The state highlighted that, while privacy is vital, it must be balanced with wider public objectives like as social security, digital governance, and administrative efficiency.

3. Privacy is not absolute, and Aadhaar is secure

The government argued that while privacy is regarded as a basic right, it is not absolute and can be limited for national security, crime prevention, and public benefit. They guaranteed that Aadhaar was optional, secure, and had appropriate protections to prevent misuse. The state asserted that strong data protection mechanisms were in place to keep resident’s biometric information secure from unwanted access.

Relevant Precedents

1. P. Sharma v. Satish Chandra (1954) held that privacy is not a basic right.
2. Kharak Singh v. State of Uttar Pradesh (1962) – Privacy was not specifically recognized as a basic right.
3. Govind v. State of Madhya Pradesh (1975) – Argued that privacy might be a basic right under Article 21.

Court’s Analysis

1. Overruling M.P. Sharma and Kharak Singh on Privacy as a Fundamental Right

The Supreme Court unanimously reversed M.P. Sharma (1954) and Kharak Singh (1962), who had earlier dismissed privacy as a fundamental right. The Court ruled that these decisions were based on a restrictive construction of basic rights that ignored the growth of constitutional jurisprudence. It highlighted that privacy is an intrinsic part of dignity, autonomy, and liberty, and hence a basic right under the Indian Constitution. This case established a progressive precedent by recognizing privacy as an enforceable right against the state.

2. Privacy derived from Articles 14, 19, and 21

The Court decided that privacy is drawn from Articles 14 (Equality), 19 (Freedom), and 21 (Life and Liberty). Article 14 safeguards individuals against arbitrary state measures, Article 19 provides freedom of expression and association, and Article 21 secures personal liberty. These rules protect privacy from both governmental and private intervention. This view established privacy as a multifaceted right, requiring that laws impacting it pass constitutional muster.

3. The Principle of Proportionality: Limiting Privacy with Justification

The decision reinforced the notion of proportionality, which requires any governmental action that restricts privacy to be justified. The Court established four criteria:

(1) legitimate objective, (2) necessity, (3) proportionality, and (4) procedural protections.

This guarantees that privacy limits are fair, justified, and not overbearing. The decision prohibited unjustified state monitoring by forcing the government to establish a compelling interest before reducing private rights, setting a higher threshold for future legislation.

4. Three dimensions of privacy: informational, bodily, and decisional

The Court divided privacy into three categories:

(1) Informational Privacy, which protects personal data from unauthorized access

(2) Bodily Privacy, which gives individuals control over their physical bodies, including medical and biometric data 

(3) Decisional Privacy, which protects personal choices such as sexual orientation, reproductive rights, and personal relationships. By acknowledging these aspects, the Court strengthened overall privacy protection.

Judgment

The Supreme Court’s 9-judge panel unanimously held that privacy is a fundamental right under the Indian Constitution. The Court ruled that privacy is a fundamental component of life, liberty, and dignity, therefore becoming an integral part of Article 21 (Right to Life and Personal Liberty). Additionally, privacy is linked to other fundamental rights under Articles 14 (Equality) and 19 (Freedom of Expression and Association). This significant decision reversed M.P. Sharma (1954) and Kharak Singh (1962), reaffirming that the Constitution is a living text that adapts to sociological and technical advances. However, the Court underlined that privacy is not an absolute right and may be subject to reasonable constraints. Any restriction on privacy must pass the proportionality test, ensuring that it serves a legitimate state purpose, is essential, and is not excessive, therefore balancing individual rights and the general good.

Impact and Significance

1. A landmark constitutional interpretation

The K.S. Puttaswamy decision improved the understanding of basic rights by clearly recognizing privacy as a constitutional right. By overruling M.P. Sharma (1954) and Kharak Singh (1962), the Supreme Court emphasized that the Constitution is dynamic and must adapt to sociological and technical advances. The decision established a higher threshold for defending individual rights, guaranteeing that privacy is more than just a legal right, but an essential component of dignity and personal liberty.

2. Aadhaar Judgment (2018)

The Puttaswamy decision paved the way for the Aadhaar case (2018), in which the Supreme Court confirmed Aadhaar’s legitimacy but placed limitations. The Court held that Aadhaar may be used for charity programs but could not be mandated for private services such as banking and cell phone communications. It also asked the government to strengthen data protection safeguards. The verdict emphasized the need to balance personal rights and governmental goals

3. Impact on Future Cases

The decision established a solid legal basis for contesting mass surveillance, data collecting, and privacy abuses. It played an important part in situations such as the Pegasus spyware affair, which raised worries about government spying. It also inspired arguments over data-sharing rules, such as WhatsApp’s recent privacy policy amendment, which ensures that businesses cannot gather or exploit user data at will. The verdict allowed people to challenge illegal governmental activities, emphasizing the importance of judicial supervision and strict privacy measures in a period of fast digital transition.

4. Personal Liberties Expanded

The acknowledgment of privacy as a basic right has a direct influence on personal liberties, notably in issues involving sexual orientation and personal autonomy. The decision was crucial in Navtej Singh Johar v. Union of India (2018), which decriminalized homosexuality by repealing Section 377 of the IPC. It also affected instances involving reproductive rights, marital autonomy, and gender identity, bolstering safeguards against governmental and community involvement. By upholding physical and decisional privacy, the decision broadened the extent of individual rights under Indian law.

Conclusion

A landmark ruling in Indian constitutional law, the K.S. Puttaswamy v. Union of India (2017) upholds privacy as a basic right guaranteed by Articles 14, 19, and 21. By guaranteeing defense against both private and governmental intrusions, it reinterpreted individual liberty. The decision has had a big impact on individual liberty, digital governance, and data protection regulations. The Court stated that any state intrusion must pass the proportionality test, guaranteeing need and legality, even if it accepted that privacy is not absolute. This ruling is a pillar of constitutional interpretation in India, continuing to influence privacy jurisprudence and direct legal concerns pertaining to digital rights, mass monitoring, and individual liberties.
