The Preamble and Making of India's Constitution

The Preamble is the opening statement of the Constitution, a single sentence that sets out who made the Constitution, the values it embodies, and the kind of state it establishes. It grew out of nearly three years of debate in the Constituent Assembly and was adopted on the day the Constitution itself was adopted, 26 November 1949. Understanding it means understanding both the body that wrote it and the exact legal status courts have since given it.

Building the Constituent Assembly

The Constituent Assembly was not directly elected by universal suffrage. It was constituted under the Cabinet Mission Plan of 1946, with members indirectly elected by the provincial legislative assemblies, plus representatives nominated by the princely states. The original strength was 389: 296 from British Indian provinces and 93 from the princely states. Partition and the departure of Muslim League members reduced this to 299 for the Assembly that actually completed the work.

The Assembly first met on 9 December 1946, with Dr. Sachchidananda Sinha, its oldest member, as temporary chairman; Dr. Rajendra Prasad was elected permanent President two days later. Sir B.N. Rau, the Constitutional Adviser, prepared the initial draft, which the Drafting Committee, formed on 29 August 1947 and chaired by Dr. B.R. Ambedkar, turned into the final text. The Assembly sat for 165 days across 11 sessions over two years, eleven months and eighteen days before adopting the Constitution on 26 November 1949; it came into force on 26 January 1950, chosen to mark the anniversary of the 1930 Purna Swaraj declaration.

Women in the Constituent Assembly

Of the Assembly's members, fifteen were women, a fact the Ministry of Law and Justice's own Legislative Department set out to correct the record on in March 2025 with a dedicated volume on their contributions, since their role had stayed largely unrecorded in standard accounts of the drafting. The fifteen were Ammu Swaminathan, Annie Mascarene, Begum Qudsia Aizaz Rasul, Dakshayani Velayudhan, Durgabai Deshmukh, Hansa Jivraj Mehta, Kamla Chaudhry, Leela Roy, Malati Choudhury, Purnima Banerjee, Rajkumari Amrit Kaur, Renuka Ray, Sarojini Naidu, Sucheta Kripalani and Vijaya Lakshmi Pandit.

A handful carry specific, testable facts beyond the headline count. Sarojini Naidu, already known as the "Nightingale of India" from the freedom movement, sat on the committee that designed the national flag and spoke in the Assembly on preserving minority unity after Partition. Hansa Jivraj Mehta sat on the subcommittee that shaped the Fundamental Rights and pushed for gender-neutral language in the text guaranteeing them. Dakshayani Velayudhan was the Assembly's only Dalit woman member and spoke against untouchability during the debates that fed into what became Article 17. Begum Qudsia Aizaz Rasul was the Assembly's only Muslim woman member, arguing for an inclusive, secular national identity at a moment when the Muslim League's own members had largely withdrawn after Partition. Rajkumari Amrit Kaur helped shape India's early public health framework and went on to become independent India's first Health Minister. Sucheta Kripalani, who spoke for labour rights inside the Assembly, later became India's first woman Chief Minister of a state, heading Uttar Pradesh's government from 1963. Durgabai Deshmukh's contributions fed directly into the Constitution's social welfare and education provisions.

The Objectives Resolution: the Preamble's first draft

Before a single article was drafted, Jawaharlal Nehru moved the Objectives Resolution on 13 December 1946, laying down the philosophy the Constitution would build on. The Assembly adopted it unanimously on 22 January 1947. It declared India would be an independent, sovereign republic drawing all power from the people, guaranteed to citizens justice, equality of status and opportunity, and fundamental freedoms of thought, expression, belief, faith, worship and action, and promised safeguards for minorities and backward and tribal areas. Nearly every phrase reappears, almost word for word, in the final Preamble, which is why the Resolution is its direct source, not merely an influence on it.

What the Preamble actually says

The Preamble opens with "WE, THE PEOPLE OF INDIA", the source of the Constitution's authority is the people themselves, not any external grant, colonial or otherwise. It then describes India as a sovereign, socialist, secular, democratic republic and commits to securing justice, liberty, equality and fraternity for every citizen, before closing with the Assembly's own act of adoption on 26 November 1949.

Each descriptive word carries a specific, testable meaning:

• Sovereign: free from external control, able to conduct its own affairs, though it may voluntarily join bodies like the UN without losing that status.
• Socialist: added by the 42nd Amendment, commits India to democratic socialism, reducing inequality through constitutional means, not state ownership of all production. India has run a mixed economy throughout.
• Secular: the State treats all religions equally and has no religion of its own. Inserted only in 1976, though the Supreme Court has held secularism was implicit in the Constitution's design (Articles 25 to 28) even before the word was added.
• Democratic: government elected by, and accountable to, the people through universal adult franchise, extending to social and economic democracy too.
• Republic: the head of state, the President, is elected, not hereditary, unlike a monarchy.
• Justice: social, economic and political, equal treatment, fair distribution of wealth, and equal political rights.
• Liberty: of thought, expression, belief, faith and worship, subject to the same reasonable restrictions Fundamental Rights carry in Part III.
• Equality: of status and opportunity, before the law and in public life.
• Fraternity: a sense of common brotherhood, assuring individual dignity and the unity and integrity of the Nation, the only ideal explicitly tied to national unity.

The 42nd Amendment's additions

The Preamble has been amended only once, by the Constitution (Forty-second Amendment) Act, 1976, enacted during the Emergency and effective from 3 January 1977. It substituted "SOVEREIGN DEMOCRATIC REPUBLIC" with "SOVEREIGN SOCIALIST SECULAR DEMOCRATIC REPUBLIC" and "Unity of the Nation" with "unity and integrity of the Nation", adding three words: Socialist, Secular and Integrity. Every other word is exactly as the Assembly wrote it in 1949.

Is the Preamble part of the Constitution: Berubari vs Kesavananda Bharati

Whether the Preamble is even part of the Constitution, not just a decorative introduction, was itself litigated. In In re Berubari Union (1960), an eight-judge bench answering a Presidential reference under Article 143 held the Preamble is a useful guide to interpretation but is not a part of the Constitution, and has no independent legal force. That position held until Kesavananda Bharati v. State of Kerala (1973), where a 13-judge bench, the largest the Supreme Court has ever assembled, held that the Preamble is part of the Constitution, since it was adopted as part of the same Constituent Assembly resolution as every other provision.

The basic structure doctrine: from Golaknath to Minerva Mills

Kesavananda Bharati is best known for the doctrine it created: Parliament's power to amend the Constitution under Article 368 reaches any provision, including Fundamental Rights, reversing the earlier Golaknath (1967) ruling that Fundamental Rights could not be amended at all, but it cannot abrogate or alter the Constitution's basic structure. Chief Justice Sikri's summary listed elements such as the Constitution's supremacy, the republican and democratic form of government, its secular character, the separation of powers, and its federal character. Later cases kept adding to this open-ended list: free and fair elections (the Indira Gandhi election case, 1975), and the balance between Fundamental Rights and Directive Principles (Minerva Mills, 1980). It has been invoked since to strike down amendments that go too far, most recently against the National Judicial Appointments Commission Act in 2015.

The doctrine did not appear fully formed in 1973. It is the fourth stop in a case sequence that each reversed or refined the one before it, and UPSC statement questions on this cluster test the specific holding of each stop, not just the order of the names.

I.C. Golak Nath v. State of Punjab (AIR 1967 SC 1643) came first. An eleven-judge bench split 6:5, with Chief Justice K. Subba Rao writing for the majority, and held that a constitutional amendment counts as "law" for the purposes of Article 13(2), the clause barring the State from making any law that abridges Part III. On that reading Parliament could not touch Fundamental Rights at all through Article 368, not even to narrow them. This overturned the Court's own earlier position in Shankari Prasad (1951) and Sajjan Singh (1965), both of which had held amendments were not "law" under Article 13 and that Parliament's amending power was unlimited. The Court applied "prospective overruling": amendments made before the 1967 judgment, including the one under challenge, stayed valid, and only future attempts to amend Fundamental Rights would be barred.

Kesavananda Bharati (1973) then went further than either extreme. Its thirteen-judge bench, sitting for 68 working days between October 1972 and March 1973 and delivering judgment on 24 April 1973, split narrowly 7:6. The majority rejected Golaknath's position that Fundamental Rights lay wholly beyond Parliament's reach, restoring Parliament's power to amend any part of the Constitution, Part III included, but replaced that blanket bar with a different, judge-made limitation instead: the word "amend" in Article 368 does not stretch to cover destroying or abrogating the Constitution's own identity, whatever elements that identity, its basic structure, turns out to include.

Indira Nehru Gandhi v. Raj Narain (1975) applied the new doctrine to an unprecedented fact pattern within two years. After the Allahabad High Court had voided Indira Gandhi's 1971 election on a corrupt-practices finding, Parliament passed the Thirty-ninth Amendment, inserting clause (4) into Article 329A to place the Prime Minister's own election beyond the reach of any court and retrospectively validate it without applying any legal standard to the underlying facts. The Supreme Court struck that clause down as violating the basic structure, holding that free and fair elections, the rule of law, and judicial review over election disputes are all part of it. Parliament, in other words, cannot legislate one individual's election dispute out of existence by constitutional amendment.

Minerva Mills Ltd. v. Union of India (1980, AIR 1980 SC 1789) closed the loop on the 42nd Amendment itself. Its Section 4 had rewritten Article 31C to give every Directive Principle in Part IV total primacy over Articles 14 and 19, and its Section 55 had inserted clauses (4) and (5) into Article 368 to declare there was no limit at all on Parliament's amending power and to place constitutional amendments beyond judicial review altogether. The Court struck down both sections, holding that a limited amending power is itself part of the basic structure, so Parliament cannot use Article 368 to convert its own limited power into an unlimited one, and that judicial review, along with the balance between Fundamental Rights and Directive Principles, is likewise part of it. Golaknath had said Fundamental Rights were untouchable; the 42nd Amendment tried to make Parliament's own amending power untouchable instead; Minerva Mills closed that route the same way Kesavananda had closed the first.

Article 368: how the basic structure limits an otherwise valid amendment

The Constitution permits three distinct routes to changing its own text, and the basic structure doctrine sits on top of all three rather than replacing any of them.

Some provisions can be changed by a simple majority of Parliament, the ordinary majority needed to pass any law, and are not even treated as amendments "under Article 368" for constitutional purposes: creating a new state or altering a state's boundaries under Article 4, converting a state into a union territory or the reverse, and similar administrative matters.

Most of the Constitution is changed by the special majority Article 368 itself prescribes: a two-thirds majority of the members of each House of Parliament present and voting, which must also amount to a majority of the total membership of that House, not merely of those present.

A smaller set of provisions, the ones touching the Centre-state balance, additionally need ratification by the legislatures of at least half the states before the President can give assent: the President's own election method, the extent of Union or state executive power, the distribution of legislative powers between them, the representation of states in Parliament, and Article 368 itself.

None of these three routes is exempt from the basic structure limitation. An amendment can clear the correct majority, and clear state ratification where that is required, and still be struck down if a court finds it damages an element of the basic structure, exactly what happened to the 39th and 42nd Amendments above despite each having gone through Parliament's ordinary amending process. The doctrine is not a fourth procedural hurdle written into Article 368's own text; it is a substantive ceiling the courts read into the word "amend" itself, which is precisely why it took a case, not a further constitutional amendment, to establish it.

The exam angle: sequence, wording and traps

UPSC statement-based questions on this cluster hinge on precise detail rather than the broad story: the exact case sequence (Berubari, 1960, Preamble not part of the Constitution; Kesavananda Bharati, 1973, Preamble is part of it), the exact words the 42nd Amendment changed (three words added, not a wholesale rewrite), and the distinction between "sovereign" (external independence) and "republic" (an elected, non-hereditary head of state), commonly confused with each other. Another recurring trap is treating "socialist" as state ownership of the whole economy, which the Constitution never mandated. Finally, the Preamble itself is not enforceable in court the way a Fundamental Right is, its value is interpretive, not a standalone source of rights.

A second cluster of traps sits in the basic structure sequence itself. Golaknath and Kesavananda Bharati are routinely confused because both look, at a glance, like the Court restricting Parliament, when the two cases in fact took opposite positions on whether Fundamental Rights specifically could be amended at all: Golaknath said no, Kesavananda Bharati said yes, subject only to the basic structure. Questions also test which case struck down which amendment: it was the 39th Amendment's Article 329A(4) that fell in the Indira Gandhi election case, and the 42nd Amendment's own attempt to insulate itself from judicial review that fell in Minerva Mills, not the other way round. On the Assembly's composition, the exact count of women members (fifteen) and which of them held a specific "first" or "only" distinction, Sucheta Kripalani as independent India's first woman state Chief Minister, Dakshayani Velayudhan as its only Dalit woman member, Begum Aizaz Rasul as its only Muslim woman member, is the kind of precise, single-fact detail this cluster's statement questions favour over broad description.

Quick revision points

• Constituent Assembly: first met 9 December 1946; Dr. Rajendra Prasad, permanent President; Drafting Committee chaired by Dr. B.R. Ambedkar. Objectives Resolution (Nehru, 13 December 1946, adopted 22 January 1947) is the Preamble's direct source.
• Preamble adopted 26 November 1949; Constitution in force 26 January 1950. 42nd Amendment (1976) added Socialist, Secular, Integrity, effective 3 January 1977, the Preamble's only amendment so far.
• Berubari (1960): Preamble not part of the Constitution. Kesavananda Bharati (1973): Preamble is part of it, and the same case created the basic structure doctrine.
• Fifteen women sat in the Constituent Assembly: Ammu Swaminathan, Annie Mascarene, Begum Qudsia Aizaz Rasul (only Muslim woman member), Dakshayani Velayudhan (only Dalit woman member), Durgabai Deshmukh, Hansa Jivraj Mehta, Kamla Chaudhry, Leela Roy, Malati Choudhury, Purnima Banerjee, Rajkumari Amrit Kaur (later India's first Health Minister), Renuka Ray, Sarojini Naidu, Sucheta Kripalani (later India's first woman state Chief Minister) and Vijaya Lakshmi Pandit.
• Basic structure case sequence: Golaknath (1967, 6:5), Fundamental Rights wholly unamendable; Kesavananda Bharati (1973, 7:6), Fundamental Rights amendable but not the basic structure; Indira Gandhi election case (1975), struck down the 39th Amendment's Article 329A(4), free and fair elections held part of the basic structure; Minerva Mills (1980), struck down the 42nd Amendment's Sections 4 and 55, limited amending power and judicial review held part of the basic structure.
• Article 368 allows three amendment routes: simple majority (outside Article 368, e.g. creating new states), special majority (two-thirds present and voting, plus a majority of total membership), and special majority plus ratification by half the states (federal provisions). The basic structure doctrine constrains all three.

Once the Assembly's timeline, the Golaknath-to-Minerva-Mills case sequence and the Berubari-to-Kesavananda distinction are clear, practise the statement-based questions UPSC builds around them.
