INTRODUCTION
Justice K.S. Puttaswamy (Retd.) v. Union of India is a cornerstone judgment and one of the most significant decisions in Indian constitutional history. The Supreme Court affirmed the Right to Privacy as a fundamental right under the Constitution of India.
The judgment emphasized that it is essential for a dignified life that an individual can make personal decisions without unwarranted interference and surveillance. It laid down important boundaries to prevent unauthorized intrusion into personal life and autonomy.
FACTS OF THE CASE
The case originated from a challenge to the Aadhaar scheme implemented by the Unique Identification Authority of India (UIDAI). In 2012, Justice K.S. Puttaswamy, a retired judge of the Karnataka High Court, filed a petition before the Supreme Court challenging the collection of biometric and demographic data under the Aadhaar scheme.
The petitioner argued that the collection of personal and sensitive information violated the right to privacy and individual autonomy under Article 21 of the Constitution.
Initially, the matter was referred to a five-judge bench. Subsequently, on 18 July 2017, it was referred to a nine-judge Constitution Bench to determine the status of the right to privacy under the Constitution.
The Government relied on earlier Supreme Court decisions in M.P. Sharma v. Satish Chandra (1954) and Kharak Singh v. State of Uttar Pradesh (1962), where the Court had held that the Constitution does not explicitly recognise a fundamental right to privacy.
KEY ISSUES
I. Whether the Right to Privacy is a fundamental right under Part III of the Constitution.
II. Whether earlier decisions in M.P. Sharma (1954) and Kharak Singh (1962) were correctly decided.
III. If privacy is a fundamental right, what is its nature and scope.
ARGUMENTS OF THE PARTIES
Petitioners’ Arguments
The petitioners contended that the collection of personal data under the Aadhaar scheme enabled state surveillance and violated the fundamental right to privacy.
They argued that privacy is intrinsic to Article 21 (Right to life and personal liberty) and includes:
• Protection against unauthorized data collection
• Personal autonomy in decision-making
• Protection from profiling and tracking
It was further argued that privacy forms part of the “golden triangle” of Articles 14, 19, and 21. The petitioners also relied on international instruments such as the Universal Declaration of Human Rights (UDHR) and the International Covenant on Civil and Political Rights (ICCPR), which recognise privacy as a fundamental human right.
Respondents’ Arguments
The Union of India argued that the Right to Privacy is not a fundamental right under the Constitution.
It relied on precedents such as M.P. Sharma and Kharak Singh, asserting that the Court should follow established jurisprudence.
The respondents further contended that privacy is an ambiguous concept and that any legal framework governing privacy should be enacted by Parliament rather than developed through judicial interpretation.
JUDGMENT
The Supreme Court, on 24 August 2017, delivered a unanimous judgment declaring that the Right to Privacy is a fundamental right under the Constitution, protected under Article 21.

The Court overruled earlier decisions in M.P. Sharma v. Satish Chandra and Kharak Singh v. State of Uttar Pradesh to the extent that they denied the existence of a fundamental right to privacy.
The judgment recognised multiple dimensions of privacy, including:
• Informational privacy (control over personal data)
• Bodily privacy
• Decisional autonomy (personal choices, including matters of identity)
The Court also established a threefold test for any state interference with privacy:
• Legality (existence of law)
• Legitimate state aim
• Proportionality (balance between means and objective)
It further clarified that the right to privacy is not absolute and may be restricted by a procedure established by law that is fair, just, and reasonable.
RATIO DECIDENDI
The Court held that privacy is a core element of human dignity and personal autonomy. It is not a privilege granted by the State but a natural and inalienable right inherent to every individual.
Privacy was recognised as an integral part of Article 21 and closely connected with Articles 14 and 19. Any restriction on this right must satisfy the tests of legality, necessity, and proportionality.
The Court also referred to comparative constitutional practices in jurisdictions such as the United States, the United Kingdom, Canada, and South Africa to reinforce its reasoning.
ANALYSIS
The Puttaswamy judgment provides a foundational framework for privacy jurisprudence in India. It establishes clear constitutional limits on state action and serves as a guide for future legislation.
The decision is particularly relevant in the digital age, where risks relating to misuse of personal data and surveillance have significantly increased. It underscores the importance of safeguarding personal information and ensuring confidentiality.
The judgment also influenced subsequent landmark decisions, including Navtej Singh Johar v. Union of India (2018) and Joseph Shine v. Union of India (2018), by linking privacy with dignity and personal liberty.
Additionally, the Court acknowledged the need for comprehensive data protection laws, although it did not lay down a detailed framework for such legislation. Some critics argue that the concept of “legitimate state aim” remains broad and requires further clarification.
CONCLUSION
Justice K.S. Puttaswamy v. Union of India is a landmark judgment that demonstrates the Supreme Court’s role in upholding constitutional values. By recognising privacy as a fundamental right, the Court strengthened the protection of individual liberty and dignity.
The decision paved the way for the development of privacy and data protection laws in India and reaffirmed that constitutional rights evolve with changing societal needs. It highlights that the Constitution is a living document and that the protection of human dignity remains central to its interpretation.
