Why this chapter matters for UPSC: The Constitution is the backbone of GS2 (Indian Polity). Every Prelims paper has multiple direct questions on Constituent Assembly facts, Preamble words, fundamental rights, DPSPs, and landmark amendments. Mains requires deep analysis — Basic Structure doctrine, constitutional morality, the tension between rights and DPSPs, and landmark cases such as Kesavananda Bharati. No GS2 topic can be answered well without a firm constitutional foundation.

PART 2 — Detailed Notes

What Is a Constitution?

Key Term

Constitution: The fundamental law of a country — a supreme document (or set of conventions) that: (1) establishes the structure of government; (2) defines the relationship between the state and its citizens; (3) protects individual rights; and (4) limits the powers of government.

Constitutions may be written (India, USA — a single codified document) or unwritten/conventional (UK — no single document; based on statutes, conventions, and precedents). India's Constitution is the longest written constitution of any sovereign nation in the world.

The Constituent Assembly

India's Constitution was not granted by colonial rulers — it was drafted by Indians, for Indians. The Constituent Assembly was composed of members elected by the Provincial Legislative Assemblies in 1946 under the Cabinet Mission Plan. It was not directly elected by the people but reflected the leadership chosen by those who had won provincial elections.

Key members and roles:

  • Dr B.R. Ambedkar — Chairman of the Drafting Committee; supervised the actual drafting of constitutional text; his encyclopaedic knowledge of constitutional law worldwide shaped every clause. Called the "Father of the Constitution." He also fought simultaneously for the rights of Dalits and marginalised communities.
  • Jawaharlal Nehru — Moved the Objectives Resolution (November 13, 1946; adopted January 22, 1947), which laid out the founding vision: sovereignty, justice, liberty, equality, fraternity. This resolution became the basis for the Preamble.
  • Dr Rajendra Prasad — President of the Constituent Assembly; later became India's first President.
  • Other Drafting Committee members: K.M. Munshi, Alladi Krishnaswami Ayyar, N. Gopalaswami Ayyangar, B.L. Mitter, D.P. Khaitan, T.T. Krishnamachari.

Women in the Constituent Assembly: Fifteen women participated, including Sarojini Naidu, Vijaya Lakshmi Pandit, Amrit Kaur (later Health Minister), Durgabai Deshmukh, and Hansa Mehta — who famously advocated that the Universal Declaration of Human Rights use "all human beings" rather than "all men."

UPSC GS2 — Constituent Assembly debates as policy history:

The CA debates (recorded in 12 volumes) are primary sources for understanding why constitutional provisions were drafted as they were. Key debates include: the choice of parliamentary over presidential system; the decision to have a single citizenship; the inclusion of DPSPs (inspired by Irish Constitution); the language issue; and the decision on federalism. The Supreme Court regularly consults CA debates when interpreting ambiguous constitutional provisions.

The Preamble

The Preamble is the Constitution's opening statement — a declaration of purpose and values. The Supreme Court in Kesavananda Bharati v. State of Kerala (1973) ruled that the Preamble is part of the Constitution and can be used to interpret its provisions.

The 42nd Amendment, 1976 (during the Emergency under Indira Gandhi) added the words "Socialist" and "Secular" to the Preamble. This is the most-tested Prelims fact about the Preamble. The original 1949 Preamble did not contain these words.

"FRATERNITY... assuring the dignity of the individual and the unity and integrity of the Nation" — the word "integrity" was also added by the 42nd Amendment.

Key Features of the Constitution

Key Term

Federal with Unitary Bias: India's Constitution establishes a federal structure (Centre + States, with separate legislatures and executive) but with strong centralising features: Article 1 uses "Union of States" (not "federation"); the Centre can legislate on State List subjects during emergencies (Articles 352, 356); Governors are appointed by the Centre; residuary powers vest in the Centre (Article 248); the Centre can override state laws in certain circumstances.

This "federal with unitary bias" character is a standard UPSC Mains answer framework for questions on Centre-State relations.

Fundamental Rights (Part III, Articles 12–35): Six categories of fundamental rights (the original seven — right to property — was removed as a Fundamental Right by the 44th Amendment, 1978; it remains a constitutional/legal right under Article 300A):

  1. Right to Equality (Articles 14–18)
  2. Right to Freedom (Article 19–22)
  3. Right against Exploitation (Articles 23–24)
  4. Right to Freedom of Religion (Articles 25–28)
  5. Cultural and Educational Rights (Articles 29–30)
  6. Right to Constitutional Remedies (Article 32 — Dr Ambedkar called this the "heart and soul" of the Constitution)

Directive Principles of State Policy (Part IV, Articles 36–51): Non-justiciable guidelines for the state to aim for — inspired by the Irish Constitution and Gandhian principles. DPSPs cover: equal pay for equal work (Article 39(d)), free legal aid (Article 39A added by 42nd Amendment), uniform civil code (Article 44), cottage industries (Article 43), Panchayati Raj (Article 40). The tension between Fundamental Rights and DPSPs was resolved by the Supreme Court in Minerva Mills (1980) — both must be given effect; neither is absolutely superior to the other.

Adoption, Artistic Legacy, and Constitutional Day

The Constitution was adopted on November 26, 1949. This date was declared Constitution Day (Samvidhan Divas) in 2015 on the initiative of Prime Minister Narendra Modi, marking the 125th birth anniversary of Dr B.R. Ambedkar.

The Constitution came into force on January 26, 1950 — chosen deliberately: on January 26, 1930, the Indian National Congress under Jawaharlal Nehru had declared Purna Swaraj (complete independence) and called on Indians to celebrate it as Independence Day. Making it Republic Day gave the date a double significance.

The original Constitution is handwritten — calligraphed by Prem Behari Narain Raizada in a flowing italic style, with each page framed in gold and decorated with scenes from Indian history by artist Nandalal Bose and his students from Shantiniketan.

UPSC GS2 — Basic Structure Doctrine:

The most important constitutional law concept for UPSC Mains: Kesavananda Bharati v. State of Kerala (1973) — a 13-judge bench of the Supreme Court (largest constitutional bench in Indian history) ruled that while Parliament has wide powers to amend the Constitution under Article 368, it cannot destroy the Basic Structure of the Constitution. What constitutes Basic Structure is not an exhaustive list, but elements include: supremacy of the Constitution; republican and democratic form of government; secular character; separation of powers; judicial review; federalism; fundamental rights.

This doctrine limits parliamentary sovereignty — Parliament, even with a two-thirds majority, cannot amend away the essence of the Constitution.

42nd Amendment (1976) — enacted during Emergency; called "Mini-Constitution" for its sweeping changes: added "Socialist" and "Secular" to Preamble; curtailed judicial review; placed DPSPs above Fundamental Rights; extended Parliament's term.

44th Amendment (1978) — reversed many 42nd Amendment changes; restored judicial review; removed Right to Property from Fundamental Rights.

Explainer

Constitutional Morality vs Social Morality: In Navtej Singh Johar v. Union of India (2018), the Supreme Court decriminalised consensual same-sex relations between adults (reading down Section 377 of IPC). Justice D.Y. Chandrachud articulated the distinction between "constitutional morality" (the values embedded in the Constitution — equality, dignity, non-discrimination) and "social morality" (prevailing public opinion, which may be majoritarian and discriminatory). Constitutional morality must prevail over social morality in a constitutional democracy. This is a key concept for GS2 Mains.

Exam Strategy

Prelims traps:

  • "Socialist" and "Secular" in Preamble = added by 42nd Amendment, 1976 (NOT original 1949)
  • Constitution adopted = November 26, 1949; in force = January 26, 1950 — do not confuse
  • President of CA = Dr Rajendra Prasad; Drafting Committee Chairman = Dr B.R. Ambedkar
  • Article 32 = Right to Constitutional Remedies (Ambedkar: "heart and soul" of Constitution)
  • Right to Property removed from Fundamental Rights by 44th Amendment, 1978 (now Article 300A)
  • Kesavananda Bharati = 1973; 13-judge bench (largest in SC history); Basic Structure doctrine

Mains angles:

  • Basic Structure Doctrine: why it matters; landmark cases (Kesavananda, Minerva Mills)
  • Constituent Assembly: who shaped the Constitution and how debates reflect policy choices
  • Preamble as guiding principle — how courts use it for interpretation
  • Tension between Fundamental Rights and DPSPs — evolution of judicial approach
  • Constitutional morality vs social morality (Navtej Singh Johar 2018)
