Right to privacy is now fully recognised as a Fundamental Right in India". Explain.

The right to privacy has now been unanimously and unequivocally recognised as a distinct fundamental right, flowing primarily from Article 21 but also drawing sustenance from Articles 14, 19, and the values enshrined in the Preamble, following the historic nine-judge bench decision in Justice K.S. Puttaswamy v. Union of India (2017). To appreciate why this recognition took nearly seven decades of constitutional evolution, one must trace the doctrine from its uncertain beginnings to its final consolidation.

The Uncertain Beginnings

The Constitution of India contains no express provision guaranteeing a right to privacy, unlike the Fourth Amendment of the American Constitution. The earliest engagement with the concept came in M.P. Sharma v. Satish Chandra, an eight-judge bench decision concerning search and seizure, where the Court declined to read any general right of privacy into the Constitution, reasoning that the framers had deliberately not incorporated an equivalent of the American Fourth Amendment. This scepticism deepened in Kharak Singh v. State of Uttar Pradesh, where the majority upheld police regulations permitting domiciliary visits and surveillance of habitual offenders, holding that "personal liberty" under Article 21 did not extend to a right of privacy since that concept found no explicit mention in the constitutional text. Yet even within this very judgment, Justice Subba Rao, writing in dissent, made a statement that would echo through the decades: though the Constitution does not expressly declare a right to privacy, it is nonetheless an essential ingredient of personal liberty, for every democratic country sanctifies the privacy of domestic life.

The Gradual Judicial Recognition

The seed sown by Subba Rao, J. germinated slowly through a series of cases even while the formal doctrinal position remained unsettled. In Govind v. State of Madhya Pradesh, the Court undertook a more elaborate appraisal of privacy, holding that a limited fundamental right to privacy could be read as an emanation from Articles 19(1)(a), 19(1)(d), and 21, though it clarified that such a right was not absolute and would have to develop through a process of case-by-case adjudication. The Court reasoned that surveillance of a habitual offender, properly regulated by statutory rules, did not offend this emerging right.

The next significant advance came in R. Rajagopal v. State of Tamil Nadu, popularly known as the "Auto Shankar" case, where the Court asserted that the right to privacy had by then acquired constitutional status, describing it as "a right to be let alone," under which a citizen may safeguard the privacy of his own life, family, marriage, procreation, motherhood, and child-bearing, though public officials could not claim this protection concerning matters relating to their public duties. This right to privacy also found reinforcement in People's Union for Civil Liberties v. Union of India, where the Court held that unauthorised telephone tapping constitutes a serious invasion of an individual's privacy, and that once facts constitute a privacy claim, Article 21 is attracted, meaning the right cannot be curtailed except by a procedure that is just, fair, and reasonable. The Court went on to lay down elaborate procedural safeguards requiring authorisation from the Home Secretary before any interception, illustrating how privacy concerns translate into binding administrative checks.

The Puttaswamy Turning Point

The persistent ambiguity was finally resolved when the constitutional validity of the Aadhaar scheme was challenged, prompting the Attorney General to argue that no fundamental right to privacy existed at all, relying on M.P. Sharma and the majority in Kharak Singh. Given the gravity of the issue, a nine-judge bench was constituted, and all nine judges spoke with one voice: the right to privacy is indeed a fundamental right protected under Part III of the Constitution.

Justice Chandrachud, writing the leading opinion for himself and three other judges, demonstrated that the doctrinal foundation of M.P. Sharma and Kharak Singh rested entirely on the discredited "mutual exclusivity theory" of A.K. Gopalan, which had already been overruled in R.C. Cooper and Maneka Gandhi. Once that foundation collapsed, the reasoning denying privacy protection could no longer stand. The learned judge concluded that privacy is a constitutionally protected right emerging primarily from the guarantee of personal liberty in Article 21, while also drawing sustenance from the other freedoms guaranteed under Part III. He prescribed that any law encroaching upon privacy must satisfy a threefold requirement: legality, meaning the existence of a law; a legitimate state aim; and proportionality, ensuring a rational nexus between the objective and the means adopted.

Justice Kaul, in his concurring opinion, memorably captured the moment of consolidation: "Let the right to privacy, an inherent right, be unequivocally a fundamental right embedded in Part III of the Constitution of India, but subject to the restrictions specified, relatable to that part". Justice Bobde identified privacy as comprising the ability to choose and specify which activities to perform and whom to include within one's personal circle, while Justice Nariman traced the right to Article 21 read with the other freedoms in Part III.

Illustrative Applications After Puttaswamy

The recognition of privacy as a fundamental right has produced concrete downstream effects across several areas of individual life. In Navtej Singh Johar v. Union of India, the Court invoked the right to sexual privacy to decriminalise consensual same-sex relations, holding that self-determined sexual orientation is a natural and inalienable facet of the right to privacy. In Selvi v. State of Karnataka, the Court held that involuntary administration of narco-analysis, polygraph tests, and brain-mapping techniques on an accused person violates both the privacy dimension of personal liberty and the protection against self-incrimination under Article 20(3). Even matters as intimate as marriage have received this protection, with the Court holding that intimacies of marriage lie within a "core zone of privacy" that remains inviolable, and that the right to marry a person of one's choice is integral to Article 21.

The Standard of Review Going Forward

The Puttaswamy bench did not merely declare privacy to be a fundamental right; it also settled the yardstick by which future restrictions on this right would be tested. Since privacy, like other fundamental freedoms, is not absolute, any law encroaching upon it must be tested on the touchstone of legality, necessity in pursuit of a legitimate state aim, and proportionality between the means adopted and the objective pursued. This proportionality framework has since guided the Court's approach in evaluating everything from Aadhaar's biometric requirements to state surveillance measures, ensuring that the individual's zone of privacy is disturbed only to the extent genuinely warranted by a compelling public interest.
