1. Chapter Overview

India has been governed by the same Constitution since 1950 — yet the country has changed enormously. This chapter explains how: through a flexible amendment procedure, judicial interpretation, and political maturity, the Constitution has remained a living, evolving document rather than a frozen rulebook.

2. Are Constitutions Static?

Many countries rewrite their constitutions when circumstances change. The Soviet Union had four constitutions in 74 years. France had five republics with new constitutions each time. India, by contrast, has been governed by the same Constitution since 26 January 1950 — over 74 years.
  • No constitution can foresee all future situations — changes are inevitable and necessary over time.
  • India’s Constitution has survived because it accepts the need for modifications according to changing needs of society.
  • Flexibility of interpretation — both political practice and judicial rulings have shown maturity, making the Constitution a living document rather than a static rulebook.
  • Constitution drafters face a challenge: provisions reflect problems of their time, but the document must also provide a framework for the future.
  • A constitution has a dual role: it is somewhat sacred (cannot be changed casually) AND it is an instrument societies create for themselves (open to revision). India’s Constitution strikes a balance between both.
🌐 Global Comparison
The US Constitution (over 200 years old) has been amended only 27 times. Switzerland allows citizens to even initiate amendments. South Africa and Russia require three-fourths majority for some amendments. India combines elements of special majority and State ratification for a balanced system.

3. How to Amend the Constitution — Article 368

Article 368 gives Parliament the power to amend the Constitution by way of addition, variation, or repeal of any provision. The makers wanted it flexible (open to change) yet rigid (protected from casual change). These two needs led to three different methods of amendment.

📝 Three Methods of Amendment

Method 1 — Simple Majority

Some articles state they can be changed ‘by law’ of Parliament — amended just like ordinary legislation with a simple majority. Examples: Article 2 (admission of new States), Article 3 (changing State boundaries). Most flexible method.

Method 2 — Special Majority (Article 368)

Amendment bill must be passed by special majority in both Houses separately. Special majority = majority of total strength of House + 2/3 of members voting. No joint session allowed. Most amendments use this method.

Method 3 — Special Majority + State Ratification

For articles affecting Centre–State relations or representation: special majority in Parliament PLUS ratification by legislatures of at least half the States (simple majority of State legislature is sufficient). Most rigid method.

🔑 Key Features of the Process

All amendments initiated only in Parliament. No constitution commission or separate body needed. President cannot send back an amendment bill for reconsideration — must give assent. No referendum required for ratification.

🔢 Understanding Special Majority — Example

📊 Lok Sabha Special Majority Calculation
Lok Sabha has 545 members (total strength). Any amendment needs support of at least 273 members (half of total strength). Even if only 300 members are present at the time of voting, the amendment still needs 273 votes. If 400 members vote → the bill needs 273 votes (half of total strength = 273 AND two-thirds of 400 = 267; the higher bar of 273 applies). Both Houses must pass separately — if one rejects, it fails.
💬 Dr. Ambedkar’s View — CAD, 25 November 1949
If those dissatisfied with the Constitution cannot obtain a 2/3 majority, their dissatisfaction cannot be deemed shared by the general public. Behind the majority lies the principle of public opinion governing decision-making.

4. Why Have There Been So Many Amendments?

By 26 January 2024, India’s Constitution had been amended 106 times in 74 years. This seems high for a relatively difficult amendment procedure. But the pattern shows amendments reflect genuine need, not just political convenience.
  • The 1970–1990 decade saw the highest number of amendments (over 20 in a single decade).
  • Between 1974–1976 (Congress domination, 352 Lok Sabha seats): 10 amendments in just 3 years.
  • Between 2001–2003 (coalition politics, BJP rivalry): again 10 amendments in 3 years — proving amendments are not solely dependent on ruling party’s strength.
  • Every decade (barring the first) has seen a steady stream of amendments — showing consistent genuine need regardless of party in power.

Category 1 — Technical / Administrative

  • Clarifications, minor modifications, explanations
  • Example: 15th Amendment — HC judges’ retirement age raised from 60 to 62 years
  • Example: 54th Amendment — increased salaries of judges
  • Example: Extensions of SC/ST seat reservations every 10 years (6 amendments so far) — no change to original provision
  • Example: Article 74(1) amended to clarify President must act on CoM advice (already the practice)

Category 2 — Differing Interpretations

  • Parliament amended Constitution to override judiciary’s interpretations it disagreed with
  • Key disputes (1970–1975): Fundamental Rights vs Directive Principles; Right to property; Parliament’s power to amend
  • Parliament repeatedly amended to overcome “adverse” judicial rulings — especially during 1970–75 Emergency period

Category 3 — Political Consensus

  • Amendments reflecting evolving consensus among political parties
  • 52nd Amendment — Anti-defection law
  • 61st Amendment — Voting age reduced from 21 to 18 years
  • 73rd and 74th Amendments — Local governments
  • 77th, 81st, 82nd Amendments — Expanding scope of reservations in jobs and admissions (post-1992 consensus)
  • 91st Amendment — Anti-defection strengthened

Category 4 — Controversial Amendments

  • 38th, 39th, 42nd Amendments — Most controversial; made during Emergency (June 1975)
  • 42nd Amendment: Changed Preamble, 7th Schedule, 53 articles; extended Lok Sabha term from 5 to 6 years; added Fundamental Duties; restricted judiciary’s review power; attempted to override Kesavananda ruling
  • Opposition MPs were in jail when passed
  • Congress lost 1977 elections; new govt reversed changes through 43rd and 44th Amendments

5. Basic Structure & Evolution of the Constitution

The most important theory shaping constitutional evolution is the Basic Structure Doctrine, emerged from the famous Kesavananda Bharati case (1973). It says: Parliament can amend any part of the Constitution, but cannot destroy its basic structure.

⚖️ Impact of Kesavananda Bharati Ruling (1973)

🚫 Limits on Parliament

Parliament cannot amend any part of the Constitution that violates or destroys its basic structure — even with special majority.

✅ Parliament’s Freedom

Parliament can amend any and all parts of the Constitution as long as the amendment does not damage the basic structure.

⚖️ Judiciary as Guardian

The Supreme Court is the final authority to decide whether an amendment violates basic structure or not.

📖 Basic Structure — Not in the Text!

There is no mention of ‘basic structure’ in the Constitution — it emerged entirely from judicial interpretation. The Judiciary informally amended the Constitution without a formal amendment.

🔑 Key Cases After Kesavananda

  • Minerva Mills case (1980): Supreme Court again upheld the basic structure doctrine, rejecting Parliament’s attempt (42nd Amendment) to assert unlimited amending power. Parliament accepted this ruling.
  • Reservations cap: Court held that reservations in jobs and educational institutions cannot exceed 50% of total seats — now an accepted principle.
  • Creamy layer (OBC reservations): Court ruled that persons in the “creamy layer” of OBC communities are not entitled to reservation benefits.
  • Right to education, right to life, minority educational institutions: Judicial interpretation expanded the meaning of these rights — informal constitutional amendments through court rulings.
  • Review Commission (2000): Government appointed Justice Venkatachaliah Commission to review the Constitution — it stuck to basic structure theory and suggested no measures endangering it.
💡 Why Basic Structure Doctrine Matters
It consolidates the balance between rigidity and flexibility: by protecting certain core features from amendment (rigid), while allowing all other parts to be amended (flexible). All political parties, governments, and Parliament have accepted this doctrine over the past five decades.

6. Constitution as a Living Document

A living document is one that keeps responding to changing situations — like a living being. India’s Constitution has survived 74+ years because it is dynamic, open to interpretation, and responsive to change — not because it is perfect or unchangeable.

🔄 Why the Constitution Has Remained Effective

📜 Formal Amendment Procedure

Three-tier system allows easy changes where needed and protects core provisions. 106 amendments in 74 years show its adaptability.

⚖️ Judicial Interpretation

Courts have expanded meanings of Fundamental Rights, created the basic structure doctrine, and developed principles like the 50% cap on reservations and creamy layer — all without formal amendments.

🤝 Political Maturity

Despite fierce battles (Parliament vs Judiciary 1967–1973), political leaders and parties ultimately accepted the basic structure doctrine and institutional limits on power.

🌟 Shared Vision

Leaders and people share a common vision: dignity and freedom of the individual, social and economic equality, national integrity. This vision — from Nehru’s “Tryst with Destiny” — has kept the Constitution as an object of respect and authority.

⚔️ Parliament vs Judiciary — The Key Tension

  • Parliament’s argument: It represents the people and therefore has responsibility to make laws for the poor, backward, and needy — even if this requires bypassing strict legal procedures.
  • Judiciary’s argument: All pro-people measures must take place within the constitutional framework. Bypassing law even with good intentions gives power holders an excuse to act arbitrarily — democracy requires checks on power too.
  • The tension was resolved by the Kesavananda ruling — which turned to the spirit of the Constitution rather than its letter, finding a balance both sides could accept.
  • The letter and spirit distinction: the intent behind a document matters more than just its text. Basic structure = features without which the Constitution cannot be imagined at all.
📣 Dissenting Voice — Constituent Assembly
Lakshminarayan Sahu, CAD, Vol. XI, 17 November 1949: The ideals on which this draft constitution is framed have no manifest relation to the fundamental spirit of India. This Constitution would not prove suitable and would break down soon after being brought into operation. — History proved him wrong.

9. Summary — Quick Revision

1

Constitutions often need revision as society changes. India has been governed by the same Constitution since 26 January 1950. The Soviet Union had 4 constitutions and France had 5 — yet India’s has survived because it accepts the necessity of change.

2

A constitution is neither so sacred that it can never be changed, nor so ordinary it can be changed like any law. India’s Constitution strikes a balance — it is a combination of both approaches: partially sacred, partially amendable.

3

Three methods of amendment: (1) Simple majority like ordinary law; (2) Special majority in Parliament under Article 368; (3) Special majority + ratification by at least half the State legislatures. All amendments are initiated only in Parliament.

4

Special majority = support of at least half the total membership of each House + two-thirds of those present and voting. Both Houses must pass the amendment separately (no joint session). President cannot withhold assent from amendment bills.

5

In 74 years, India’s Constitution has been amended 106 times. Amendments fall into three categories: technical/administrative, differing interpretations (Parliament vs Judiciary), and amendments through political consensus (e.g. voting age reduction, anti-defection, local govt).

6

The 42nd Amendment (Emergency, 1975) was the most controversial — changed the Preamble, 7th Schedule, and 53 articles; extended Lok Sabha term to 6 years; restricted judiciary’s review power. Congress lost 1977 elections; 43rd and 44th Amendments reversed most changes.

7

The Kesavananda Bharati case (1973) gave the Basic Structure Doctrine: Parliament can amend any provision but cannot destroy the basic structure of the Constitution. Supreme Court is the final authority to decide what constitutes basic structure.

8

The basic structure doctrine is not mentioned anywhere in the Constitution — it emerged from judicial interpretation. This is itself an example of a living constitution. All political parties and institutions have accepted this doctrine over five decades.

9

Other examples of judicial interpretation changing the Constitution: 50% cap on reservations, creamy layer principle for OBC reservations, expansion of right to life and education — all without formal amendments.

10

The Constitution has survived because of three factors: a flexible-yet-protective amendment procedure, maturity of political leadership in accepting institutional limits, and a shared national vision of individual dignity, equality, and national integrity.

10. Important Terms to Remember

  • Article 368: The constitutional provision that grants Parliament the power to amend the Constitution by way of addition, variation, or repeal of any provision. Lays down the procedure for special majority amendments.
  • Special Majority: The requirement that an amendment bill must be supported by at least half of the total strength of each House and by at least two-thirds of those present and voting — both Houses passing it separately.
  • Flexible Constitution: A constitution that can be easily amended or modified — like parts of the Indian Constitution changeable by simple majority of Parliament.
  • Rigid Constitution: A constitution where certain provisions are very difficult to change — requiring special majority and/or State ratification, as in India’s federal provisions.
  • Basic Structure Doctrine: Judicial theory (Kesavananda Bharati case, 1973) that Parliament can amend any part of the Constitution but cannot destroy its basic or essential structure. Not mentioned in the Constitution — created by judicial interpretation.
  • Kesavananda Bharati Case (1973): Landmark Supreme Court ruling that established the Basic Structure Doctrine, resolving the conflict between Parliament’s amending power and judicial review. Has governed all constitutional interpretations since.
  • 42nd Amendment (1976): The most controversial amendment — made during the Emergency — which changed the Preamble, 53 articles, and 7th Schedule. Most of its changes were reversed by the 43rd and 44th Amendments.
  • Living Document: A constitution that keeps evolving through formal amendments and judicial interpretation to respond to changing social, political, and economic circumstances — as opposed to a frozen, static document.
  • Parliamentary Sovereignty: The principle that only elected representatives of the people have the power to consider and take final decisions on constitutional amendments — no outside agency (referendum, commission) is required.
  • Creamy Layer: A judicial concept introduced by the Supreme Court for OBC reservations — persons in the higher income/status group of OBC communities are not entitled to reservation benefits, as they are sufficiently advanced.
