Indian Constitution — Features, Basic Structure & Amendments

The Constitution is the single highest-weight GS-II theme and the backbone of most polity answers. UPSC expects you to know its salient features, the basic structure doctrine, and the amendment process, and to argue about the balance between constitutional flexibility and its inviolable core.

Salient features

Lengthiest written constitution; a blend of rigidity and flexibility; parliamentary government; quasi-federal (federal with a unitary bias); fundamental rights (Part III) balanced by Directive Principles (Part IV) and Fundamental Duties (Part IVA, 42nd Amendment); independent judiciary with judicial review; single citizenship; and universal adult franchise.

Basic structure doctrine

Evolved in Kesavananda Bharati v. State of Kerala (1973): Parliament can amend any part under Article 368 but cannot destroy the "basic structure" — supremacy of the Constitution, rule of law, judicial review, secularism, federalism, separation of powers, free and fair elections. Reaffirmed in Minerva Mills (1980), Indira Gandhi v. Raj Narain (1975).

Element	Provision	Note
Amendment power	Article 368	Simple / special / special+state ratification
Basic structure	Judge-made (1973)	Limits amending power
Fundamental Rights	Part III	Justiciable
DPSP	Part IV	Non-justiciable, guiding

Exam Tricks & Tips

• 🎯 Anchor every basic-structure answer to Kesavananda Bharati (1973) and name 3-4 basic features.
• 🎯 Distinguish the three amendment routes under Article 368 (simple majority items, special majority, special + half the states).
• 🎯 Frame the Constitution as "living" — flexible enough to adapt yet protected by an inviolable core.
• 🎯 Use the FR-DPSP balance (Minerva Mills) to discuss harmony between rights and social goals.
• 🎯 Cite borrowed features (parliamentary from UK, FRs from US, DPSP from Ireland) for context.
• ❌ Do not call India "purely federal" — it is quasi-federal / "federal with a unitary bias" (K.C. Wheare).

Expected question pattern

"The basic structure doctrine balances constitutional flexibility with its core — discuss", "Examine the harmony between Fundamental Rights and Directive Principles", or the nature of Indian federalism.

Quick recap

Know the salient features, the basic structure doctrine (Kesavananda Bharati 1973) and its protected core, and the Article 368 amendment routes. Present the Constitution as a living document — flexible yet anchored by an inviolable basic structure.

Cover the answer, recall, then check. 12 cards on the Constitution for UPSC Mains.

Q1. Which case established the basic structure doctrine and when?
A1. Kesavananda Bharati v. State of Kerala, 1973 — Parliament can amend the Constitution but cannot alter its basic structure.

Q2. Name four elements of the basic structure.
A2. Supremacy of the Constitution, rule of law, judicial review, secularism, federalism, separation of powers, free and fair elections (any four).

A3. Article 368, providing special-majority amendment, some with ratification by half the states.

Q4. What are the three routes of constitutional amendment?
A4. By simple majority (certain provisions), by special majority of Parliament, and by special majority plus ratification by half the state legislatures.

Q5. How is Indian federalism best described?
A5. Quasi-federal — federal in form with a strong unitary/centralising bias (K.C. Wheare); "an indestructible union of destructible states".

Q6. Distinguish Fundamental Rights and Directive Principles.
A6. FRs (Part III) are justiciable individual rights; DPSPs (Part IV) are non-justiciable guidelines for the state to achieve socio-economic justice.

Q7. Which case affirmed the FR-DPSP balance as basic structure?
A7. Minerva Mills v. Union of India (1980) held the harmony between FRs and DPSPs to be part of the basic structure.

Q8. From where were key features borrowed?
A8. Parliamentary system and rule of law (UK), Fundamental Rights and judicial review (US), DPSP (Ireland), emergency provisions (Germany), and the concurrent list (Australia).

Q9. Which amendment added Fundamental Duties?
A9. The 42nd Amendment (1976) added Part IVA (Article 51A), originally 10 duties (now 11).

Q10. What did the 42nd Amendment add to the Preamble?
A10. The words "Socialist", "Secular" and "Integrity".

Q11. Can Parliament amend Fundamental Rights?
A11. Yes, under Article 368, but not so as to damage the basic structure (post-Kesavananda), overruling the earlier Golaknath view.

Q12. What is judicial review?
A12. The power of courts to examine and strike down legislative/executive actions that violate the Constitution — itself part of the basic structure.

The Constitution is the heart of GS-II, and the basic-structure doctrine is its single most examined idea ("The basic structure doctrine is a bulwark of constitutionalism but sits uneasily with parliamentary sovereignty — critically examine"). The strong answer combines constitutional facts with the deeper debate between parliamentary supremacy and judicial review.

What this topic covers and why it matters

UPSC tests whether you understand the Constitution as a living document — its salient features, how it can be amended, and the judicially-crafted limit (basic structure) that keeps amendment power from destroying the Constitution's identity. This underlies almost every polity question.

Salient features

A lengthy written Constitution; a blend of rigidity and flexibility; parliamentary government; quasi-federal (a "federation with a strong centre" / "Union of States"); fundamental rights and directive principles; an independent judiciary with judicial review; universal adult franchise; single citizenship; and secularism. It borrows selectively (parliamentary system from Britain, judicial review from the US, DPSPs from Ireland, emergency provisions from Germany) yet synthesises a distinctly Indian document.

The amendment process (Article 368)

• Three modes: by simple majority (some provisions, outside 368), by special majority (most provisions), and by special majority plus ratification by half the states (federal provisions).
• The process balances flexibility (over 100 amendments) with entrenchment of the federal core.

The basic structure doctrine — the constitutional evolution

• Shankari Prasad (1951) and Sajjan Singh (1965): Parliament can amend even fundamental rights.
• Golaknath (1967): reversed — fundamental rights cannot be amended.
• 24th Amendment + Kesavananda Bharati (1973): the landmark. The Court held Parliament can amend any part including fundamental rights, but cannot alter the "basic structure" of the Constitution.
• Reaffirmed: Indira Nehru Gandhi (1975), Minerva Mills (1980 — balance between rights and DPSPs; judicial review as basic structure), Waman Rao, and the NJAC judgment (2015).
• Illustrative basic features: supremacy of the Constitution, rule of law, separation of powers, judicial review, federalism, secularism, free and fair elections, and the dignity of the individual.

Answer-writing application

For "Basic structure — judicial overreach or democratic safeguard?":

• Intro: Kesavananda as the fulcrum of Indian constitutionalism.
• Body: the case for the doctrine (prevents majoritarian destruction of the Constitution, protects rights and federalism — validated during the Emergency); the critique (undemocratic limit on an elected Parliament, judicially undefined and open-ended); the balance (Minerva Mills' equilibrium).
• Conclusion: the doctrine as a pragmatic guarantor of constitutional identity.

Linkages

Connects to separation of powers and judiciary (same subject), fundamental rights and DPSPs, federalism (basic feature), and Ethics (constitutional morality). It frames debates on any constitutional amendment (e.g., reservation, federalism).

Value-addition

Cite Kesavananda Bharati (1973), Minerva Mills (1980), and NJAC (2015); quote Granville Austin ("the Constitution is first and foremost a social document") and the "cornerstones of a nation" framing; note the borrowed-features synthesis and the idea of "constitutional morality" (Ambedkar, via Grote).

Worked Example

Problem/Question: "The Basic Structure doctrine has preserved constitutionalism while limiting parliamentary sovereignty." Critically examine. (15 marks)
Solution/Model answer:
Intro: Evolved in Kesavananda Bharati (1973), the doctrine holds that Parliament may amend the Constitution under Article 368 but cannot destroy its "basic structure".
Body — how it preserves constitutionalism:

• Protects core features — judicial review, rule of law, separation of powers, secularism, federalism, free and fair elections.
• Struck down overreaching amendments (39th in Indira Nehru Gandhi; parts of 42nd in Minerva Mills).
• Prevents transient majorities from subverting the Constitution.
  Critical counterpoints:
• The doctrine is judge-made and lacks explicit textual basis ("counter-majoritarian" concern).
• Its contours are open-ended, giving the judiciary wide discretion.
• Tension with parliamentary sovereignty and the democratic mandate (e.g., the NJAC verdict debate).
  Conclusion: On balance, the doctrine is a vital safeguard that has kept Indian constitutionalism resilient; the answer lies in judicial restraint and reasoned application rather than abandoning it.
  Answer/Takeaway: The Basic Structure doctrine is an indispensable, if judge-made, guardrail that protects the Constitution's core against amendment while raising legitimate questions about judicial discretion and democratic will.
