In November 1948, Dr. B.R. Ambedkar told the Constituent Assembly that constitutional morality "is not a natural sentiment. It has to be cultivated. We must realise that our people have yet to learn it. Democracy in India is only a top-dressing on an Indian soil which is essentially undemocratic." For sixty years, the phrase sat in the Constituent Assembly Debates, unused. Then the Supreme Court rediscovered it. Today, constitutional morality is one of the most-invoked interpretive principles in Indian constitutional law — the lens through which the Court has read rights cases on sexuality, religion, equality, and the relationship between social custom and constitutional values. For Prelims, you need the origin of the phrase, its modern revival, and how it connects to the broader theory of constitutional interpretation.
Ambedkar in the Constituent Assembly
The phrase comes from Ambedkar's speech of 4 November 1948 introducing the Draft Constitution to the Constituent Assembly. He was answering a critical objection — that the Constitution loaded too much administrative detail into its text and would have been better as a brief statement of principles. Ambedkar's response was that detail was needed because India's social fabric did not yet have the political habits that constitutional democracy presupposed.
He drew the phrase from George Grote, the historian of Greece, who had used "constitutional morality" to describe the political culture of ancient Athens — a paramount reverence for constitutional forms, combined with self-restraint and willingness to disagree within the rules. Ambedkar applied the concept to India. Without constitutional morality — the disposition to respect constitutional procedures even when they produce inconvenient results — democratic forms would not survive.
The full passage is worth holding: "Constitutional morality is not a natural sentiment. It has to be cultivated. We must realise that our people have yet to learn it. Democracy in India is only a top-dressing on an Indian soil which is essentially undemocratic." Ambedkar's worry was that without constitutional morality, the Constitution's words would be honoured in form but ignored in substance. The detail in the constitutional text was a substitute for the political culture that did not yet exist.
The dormant period — 1948 to 2009
For the next six decades, the phrase "constitutional morality" was rarely used. Constitutional cases were decided on the substantive provisions of the Constitution — the Fundamental Rights, the federal scheme, the procedural safeguards. The Supreme Court developed the basic structure doctrine in 1973, the doctrine of public interest litigation in the 1980s, and the modern reading of Article 21 in Maneka Gandhi (1978). None of these cases used the phrase "constitutional morality" as a working concept.
The reasons for this silence are not entirely clear. One reading is that the phrase belonged to constitutional theory rather than constitutional adjudication — a description of political culture rather than a tool of legal reasoning. Another reading is that the early Court was busy establishing the basic vocabulary of Indian constitutional law and had no need for an additional interpretive concept.
Whatever the reason, the phrase lay dormant in the Constituent Assembly Debates until the Delhi High Court revived it in 2009. The revival was specific in occasion and scope, but it triggered a sustained engagement that has continued to the present.
The Naz Foundation revival
The Delhi High Court's judgment in Naz Foundation v. Government of NCT of Delhi (2009) revived the phrase. The case concerned Section 377 of the Indian Penal Code, which criminalised "carnal intercourse against the order of nature" — used historically to criminalise consensual same-sex relations between adults. The challenge was that Section 377 violated Articles 14, 15, and 21.
The Delhi High Court read down Section 377 to exclude consensual sex between adults in private. In doing so, the Court invoked Ambedkar's phrase. The Court held that "popular morality" — the prevailing social attitude towards a practice — could not be the test for the constitutionality of a law. The proper test was constitutional morality — the values embedded in the Constitution itself, including dignity, equality, and the protection of individual autonomy.
The distinction between popular morality and constitutional morality became the doctrinal core of the case. A practice could be socially disapproved but constitutionally protected if it engaged a fundamental right. The Court was not bound by the moral consensus of the majority; it was bound by the moral architecture of the Constitution.
The judgment was overruled by the Supreme Court in Suresh Kumar Koushal (2013), which restored Section 377. But the phrase "constitutional morality" survived — and was deployed with greater force when the Supreme Court itself revisited the issue in Navtej Singh Johar (2018), unanimously decriminalising consensual same-sex relations and explicitly affirming the Naz Foundation framework.
Sabarimala and the high-water mark
The most controversial application of constitutional morality came in Indian Young Lawyers Association v. State of Kerala (2018) — the Sabarimala case. The Sabarimala temple in Kerala had historically excluded women between the ages of 10 and 50 from entry, on the ground that the deity at the temple, Lord Ayyappa, was a celibate.
The Supreme Court, by a 4:1 majority, held that the exclusion violated Articles 14, 15, 17, and 25. The judgment by Chief Justice Misra and the concurring opinion by Chandrachud J. invoked constitutional morality extensively. The reasoning was that religious practices, even those rooted in long tradition, must be tested against constitutional values — and that the exclusion of women on the basis of biological characteristics violated equality and dignity.
The dissent by Indu Malhotra J. cautioned against the use of constitutional morality to override religious autonomy. She argued that constitutional morality, untethered to specific constitutional provisions, could become a roving licence for judges to impose their own values on religious communities. The dissent's concern — that constitutional morality is too elastic — has resonated in subsequent academic critique.
The Sabarimala judgment is significant for three reasons. First, it deployed constitutional morality as a primary doctrinal tool, not merely a rhetorical flourish. Second, it applied the concept to a religious practice, expanding its reach beyond the privacy and equality cases. Third, it provoked an open argument about the limits of the concept — an argument that has continued in subsequent cases and in academic writing.
How constitutional morality differs from basic structure
Constitutional morality and the basic structure doctrine are sometimes confused. They are different tools.
The basic structure doctrine is a limit on Parliament's amending power. It applies to constitutional amendments under Article 368 and (after Coelho) to Ninth Schedule entries. The doctrine asks whether an amendment damages or destroys the basic structure of the Constitution. Its operation is structural — it preserves the constitutional architecture against legislative override.
Constitutional morality is an interpretive principle. It applies when the Court is reading rights provisions to decide whether a particular law or practice is constitutional. The principle asks whether the law or practice conforms to the values embedded in the Constitution. Its operation is interpretive — it shapes how the substantive provisions are read.
The two principles can converge. A law that violates constitutional morality may also damage the basic structure if it is enacted by constitutional amendment. But they operate at different levels: basic structure restrains the amending power; constitutional morality guides the reading of existing rights. For aspirants, the difference can be tested as a Prelims trap — confusing one with the other has been a common error.
The critique — and the limits
Constitutional morality has been criticised on several grounds. The strongest critique is that it is indeterminate. The basic structure doctrine, despite being judge-made, has produced a workable list of features — judicial review, federalism, separation of powers, the limited amending power, equality. Constitutional morality has no such list. It is invoked case by case, with the Court drawing on different constitutional values in different contexts.
A related critique is that it can become a licence for judicial imposition. Without firm anchors in specific constitutional text, constitutional morality risks becoming whatever the Court at any given moment thinks it should be. The Sabarimala dissent made this point sharply. Critics have argued that the concept gives the judiciary a tool to override democratic and religious self-government on the basis of values that are not clearly traceable to the constitutional text.
Defenders of the concept respond that all constitutional adjudication involves interpretation — the question is not whether judges should reason from constitutional values, but how they should do it. Constitutional morality, on the defenders' view, simply names what was always happening: the Court reading rights provisions in light of the broader constitutional purpose, including the Preamble, the architectural choices made by the framers, and the values they embedded in the document.
One additional historical detail. Ambedkar's worry about the absence of constitutional morality in India was not abstract. He pointed to specific failures — the persistence of caste hierarchies, the social acceptance of practices that the Constitution would prohibit, the lack of habits of toleration and dissent that democracy required. The phrase "constitutional morality" was, in Ambedkar's mouth, a sociological diagnosis as well as a legal-theoretical concept.
One subtle but important point worth holding. Constitutional morality, despite its modern prominence, is not a single doctrine with a fixed test. Different judges have used the principle in different ways. Justice Chandrachud has tended to read it through the lens of dignity and individual autonomy. Chief Justice Misra in Sabarimala used it to test religious practices against equality norms. Justice Indu Malhotra, in dissent in Sabarimala, used the principle in a narrower way — to caution against using broad constitutional values to override specific religious or community traditions. The principle is being shaped case by case; aspirants who present it as a settled doctrine miss the live debate.
The breadth of the cases applying constitutional morality is worth noting. The Court has invoked the principle in Manoj Narula v. Union of India (2014) to limit ministerial appointments where serious criminal charges had been framed; in Government of NCT of Delhi v. Union of India (2018) to limit the Lieutenant-Governor's powers in Delhi; in Joseph Shine v. Union of India (2018) to strike down the criminal offence of adultery in Section 497 IPC. Each application has involved reading constitutional values into specific provisions to produce results that would not have followed from a literal textual reading alone.
The expansion of the principle has not been without controversy within the Court itself. In Riju Prasad Sarma v. State of Assam (2015), the Court urged caution. The principle should not become a "blanket cover" for judicial preferences. The proper application requires the Court to anchor constitutional morality in specific constitutional values — equality under Article 14, dignity under Article 21, fraternity in the Preamble — rather than in free-floating moral judgment.
The debate is not settled. Constitutional morality remains a working tool of the Supreme Court, but its limits and its proper application are still being worked out. For Prelims, aspirants should know the phrase, its origin, its modern revival, and the major cases — but should not present it as a fully formed doctrine with sharp edges.
What students must hold
Four points carry the weight. One, the phrase "constitutional morality" originates with Ambedkar in his 4 November 1948 speech to the Constituent Assembly. Ambedkar drew it from George Grote's history of Greece. The phrase was dormant for sixty years.
Two, the modern revival began with the Delhi High Court's Naz Foundation judgment (2009) on Section 377. The Court drew the distinction between popular morality (social consensus) and constitutional morality (values in the Constitution). The distinction has driven subsequent cases.
Three, the high-water mark is Sabarimala (2018), where the majority used constitutional morality to override a religious practice. The dissent worried about elasticity and judicial overreach.
Four, constitutional morality is interpretive (guides reading of rights); basic structure is structural (limits amendments). Don't confuse the two — Prelims has tested this disambiguation. For more on rights-interpretation cases that have used the principle, see the broader Fundamental Rights notes.
