Critically evaluate the scope of the expression 'Personal Liberty' in Article 21 of the Constitution of India. Do you think that the expression 'procedure established by law' in Article 21 introduces India, the American 'due process clause' on the subject? Discuss.

The expression "personal liberty" in Article 21 has expanded from a narrow physical concept into a compendious guarantee covering nearly every facet of human dignity and autonomy, while "procedure established by law" has, through judicial interpretation, come to function almost identically to the American due process clause—even though the framers deliberately rejected that very phrase. Understanding this transformation requires walking through the evolution of both expressions, examining the judicial reasoning that reshaped them, and honestly confronting the debate over whether India has, in substance if not in name, adopted due process.

The Narrow Beginning: Personal Liberty in Gopalan

When Article 21 first came before the Supreme Court in A.K. Gopalan v. State of Madras, the majority gave "personal liberty" the most restrictive reading imaginable. The petitioner, detained under the Preventive Detention Act, argued that his detention violated the freedom of movement guaranteed under Article 19(1)(d), which he described as the very essence of personal liberty. The Court rejected this, reasoning that the word "liberty" is qualified by "personal," a narrower term, and that personal liberty therefore means only liberty relating to the physical body of the individual—freedom from arrest and confinement, nothing more. This view drew directly on Dicey's English conception of personal liberty as protection against imprisonment and physical coercion. Justice Fazl Ali alone dissented, giving the phrase a wide and comprehensive meaning encompassing freedom of movement and locomotion, and insisting that any law depriving personal liberty must satisfy both Article 19 and Article 21.

The majority also erected what became known as the "mutual exclusivity" or "silo" theory: Articles 19, 21, and 22 were treated as separate, watertight compartments, each governing a distinct subject matter, so that a preventive detention law needed only to satisfy Article 22 and remained wholly immune from Article 19 scrutiny. This meant courts could not ask whether a detention law was reasonable—only whether a validly enacted law existed and was formally followed.

Kharak Singh: The Compendious Expression Emerges

The real expansion began in Kharak Singh v. State of Uttar Pradesh, where the Court had to examine police regulations permitting domiciliary visits and surveillance of habitual offenders. Here the Court described personal liberty as "a compendious term to include within itself all the varieties of rights which go to make up the personal liberty of man" other than those specifically named in Article 19(1). Article 19(1) dealt with particular species of freedom, while personal liberty in Article 21 comprised the residue—everything else that liberty implies. On this basis, night-time domiciliary visits disturbing a person's sleep were held to violate personal liberty, though mere shadowing of movements was placed under Article 19(1)(d) instead.

It was Justice Subba Rao's dissent in Kharak Singh, however, that proved prophetic. He defined personal liberty as "a right of an individual to be free from restrictions or encroachments on his person, whether those restrictions... are directly imposed or indirectly brought about by calculated measures". He rejected the majority's compartmentalisation, insisting that Articles 19 and 21 overlap rather than exclude one another, since "the fundamental right of life and personal liberty have many attributes and some of them are found in Article 19". In a later case, State of Maharashtra v. Prabhakar Pandurang Sanzgiri, Subba Rao, J. mapped out five distinct ways Articles 19 and 21 might interact, exposing how thin the majority's reasoning in Gopalan actually was.

RC Cooper and Maneka Gandhi: Overruling the Silos

The turning point came in R.C. Cooper v. Union of India (the Bank Nationalisation case), where the Supreme Court held that the extent of protection against infringement of a fundamental right must be judged by its direct effect on the individual, not by the form or object of the legislating authority—effectively rejecting Gopalan's premise that each fundamental right operates in isolation. This paved the way for Maneka Gandhi v. Union of India, where Mrs. Gandhi's passport was impounded under Section 10(3)(c) of the Passport Act without being given reasons or a hearing.

Justice Bhagwati, writing the leading opinion, declared personal liberty to be "of the widest amplitude," covering a variety of rights that constitute the personal liberty of man, some of which have been elevated to distinct fundamental rights with additional protection under Article 19. He held that Articles 14, 19, and 21 are not mutually exclusive but interlinked, so any law depriving personal liberty must pass a triple test: it must prescribe a procedure, that procedure must withstand the reasonableness test of Article 19, and it must not violate Article 14's equality guarantee. Krishna Iyer, J. added memorably that "the spirit of man is at the root of Article 21; personal liberty makes for the worth of the human person, and travel makes liberty worthwhile".

Illustration: How the Scope Changed in Practice

Consider preventive detention. Under Gopalan, if a detenu challenged restrictions on meeting his lawyer or family, courts would ask only whether a valid statute authorised it—end of inquiry. After Maneka, the same restriction would be tested for reasonableness under Article 19 and non-arbitrariness under Article 14. This shift proved decisive in later cases: in Francis Coralie Mullin, the right to have interviews with family and legal counsel was read into personal liberty as part of living with dignity, and in Prabhakar Pandurang, denying a detenu permission to send a manuscript to his wife for publication was struck down as an unconstitutional infringement of personal liberty, since no law expressly prohibited it.

By the time of Puttaswamy, this trajectory had gone so far that a commentator observed Article 21 "has now come to be invoked almost as a residuary right, even to the extent which the founding fathers never dreamt of".

The Due Process Question: Text, History, and Judicial Practice

Turning to the second and more contested question—whether "procedure established by law" has effectively imported American due process—the answer requires separating three things: constitutional history, the Gopalan-era denial, and the post-Maneka reality.

The historical debate. The popularly accepted account holds that constitutional advisor B.N. Rau, on Justice Felix Frankfurter's advice during his 1947 American visit, caused the phrase "due process of law" to be replaced with "procedure established by law," borrowing instead from Article 31 of the Japanese Constitution. However, this account has been seriously challenged by more recent scholarship, which shows that the Drafting Committee had maintained consensus in favour of retaining due process until as late as January 1948, and that the substitution occurred rather abruptly in February 1948 without full deliberative consensus. When an amendment was moved in the Constituent Assembly to restore due process, Dr. Ambedkar candidly admitted the dilemma: legislatures might pass unjust laws, but equally, a handful of judges deciding validity based on personal conscience posed its own danger—he said he would "leave it to the House to decide in any way it likes". The amendment was defeated.

Gopalan's flat rejection. The Supreme Court in Gopalan held unambiguously that the difference between "due process" and "procedure established by law" was deliberate and material—Article 21 required only a validly enacted law, and courts would not examine its fairness or content. This view persisted for decades; in A.K. Roy v. Union of India, Chief Justice Chandrachud explicitly distinguished procedural from substantive due process, holding that only the former—testing whether the procedure is fair—could be read into Article 21, not the latter, which would allow courts to judge the fairness of the substance of laws.

Maneka's transformation. Yet Maneka Gandhi effectively reintroduced due process through interpretive means without using the term. Bhagwati, J. held that the procedure under Article 21 must be "right, just and fair," not "arbitrary, fanciful or oppressive," reasoning that the principle of reasonableness embedded in Article 14 must permeate Article 21 "like a brooding omnipresence". Krishna Iyer, J. went further, holding that not just the procedure but the law itself must be reasonable—effectively demanding due process in the American sense. He later stated in Sunil Batra v. Delhi Administration: "True our Constitution has no due process clause, but after Cooper and Maneka Gandhi, the consequence is the same. Article 21 is the counterpart of the procedural due process in the United States".

Substantive due process creeping in. The debate did not stop at procedural fairness. In Selvi v. State of Karnataka, Chief Justice Balakrishnan asserted that "the standard of substantive due process is... the threshold for examining the validity of all categories of governmental action that tend to infringe upon personal liberty". Nariman, J., in Mohd. Arif v. Supreme Court of India, went even further, declaring that "the wheel has turned full circle. Substantive due process is now a part and parcel of Article 21", a position he repeated in Shayara Bano and in his concurring opinion in Puttaswamy while grounding the right to privacy in it.

A more cautious counter-view. Justice D.Y. Chandrachud, however, sounded a note of caution in Puttaswamy, observing that "even in the country of its origin, substantive due process has led to vagaries of judicial interpretation," and that given the deliberate constitutional history behind deleting the phrase, "it would be inappropriate to equate the jurisdiction of a constitutional court in India... with the exercise of substantive due process under the US Constitution". He suggested that what courts really do is mount a "substantive challenge to the validity of a law" on the ground that its provisions violate constitutional guarantees—a different, more textually grounded exercise than open-ended American substantive due process.

A Critical Assessment

On balance, the evidence supports a nuanced middle position rather than a flat yes or no. Procedurally, India has undeniably absorbed the functional equivalent of due process—no serious scholar disputes that post-Maneka, a law depriving personal liberty must be substantively reasonable, non-arbitrary, and fair, which is precisely what procedural due process demands in the American system. This was achieved not by textual amendment but by judicial reinterpretation binding Articles 14, 19, and 21 together as an integrated code of fairness.

Where genuine controversy persists is over full-blown substantive due process—the power of courts to strike down laws merely for embodying policies the judiciary considers unwise or oppressive in substance, independent of procedural fairness. Nariman, J.'s repeated invocations of this doctrine sit uneasily against the deliberate constitutional choice to excise "due process," and against Ambedkar's own anxiety about handing unelected judges the power to invalidate legislative policy on subjective grounds. Chandrachud, J.'s more restrained formulation—that courts merely test whether the substantive provisions of a law violate express or implied constitutional guarantees, rather than exercising an open-ended American-style substantive due process—appears both more textually faithful and more consistent with the framers' considered rejection of that clause. The honest conclusion, therefore, is that "procedure established by law" has been judicially transformed into something functionally indistinguishable from procedural due process, while the extension to full substantive due process remains doctrinally unsettled and, in the more careful judicial opinions, is treated as a distinct and narrower form of substantive review grounded in the Constitution's own text rather than an imported American doctrine.
