Constitution as a Living Document
Start here: why this chapter matters
This chapter ties the book together: how the Constitution is amended (Article 368), why it has been amended so often, why the 42nd Amendment was so controversial, and how the basic structure doctrine limits Parliament while letting the Constitution grow.
- Builds on Chapter 2 (FRs vs DPSPs, property), Chapter 5 (special majority, Rajya Sabha), Chapter 6 (judicial review, Kesavananda) and Chapter 7 (federal provisions).
- Leads to Chapter 10 (the philosophy of the Constitution).
- UPSC: GS2 ‘amendments, significant provisions and basic structure’ — Article 368, ratification, the 42nd/44th, Ninth Schedule and basic structure are Prelims favourites and a recurring Mains theme.

- The box traces France's constitutions: the post-revolution constitution of 1793 (first republic), the second republic in 1848, the third in 1875, the fourth in 1946 and the fifth in 1958. (Beyond NCERT: the First Republic was proclaimed in 1792, and the 1793 constitution was never applied.)
- A girl on roller skates observes that constitutional changes seem closely linked to political developments — the theme of the whole chapter.
At a glance — the six ideas to carry away
- India: same Constitution since 26 January 1950; USSR four constitutions (1918–1977), Russia a new one in 1993, France five republics.
- Three routes: simple majority (‘by law’, e.g. Arts 2–3); special majority (Art. 368); special majority + half the States.
- Special majority = half the total membership and two-thirds of those voting, in each House separately; no joint sitting; President cannot return the bill.
- 106 amendments by 26 January 2024 (NCERT): technical, interpretation-driven, consensus-based, controversial.
- 42nd (1976): Preamble, Seventh Schedule, 53 articles, Lok Sabha term 6 years, Fundamental Duties; mostly reversed by 43rd and 44th.
- Basic structure: Kesavananda Bharati (1973), Minerva Mills (1980); Venkatachaliah review commission (2000) respected it.
1. Are constitutions static?
The Soviet Union had four constitutions in 74 years (1918, 1924, 1936, 1977); after Communist rule ended in 1991 and the federation broke up, Russia adopted a new constitution in 1993. India's Constitution was adopted on 26 November 1949 and came into force on 26 January 1950, and still frames government. Why? The framers were farsighted and the framework suits India — but no document can foresee everything. The answer: the Constitution accepts modification, and political practice and judicial rulings have interpreted it flexibly — making it a living document, not a closed rulebook.
Every constitution reflects the problems of its own time and must also guide the future. It expresses a society's aspirations, and it is a tool the society made for itself. Is it sacred and unchangeable, or an ordinary law? The framers struck a balance: above ordinary law and deserving respect, yet open to change as opinion shifts.
- A boy notes that the US Constitution is more than 200 years old and has been amended only 27 times (still 27 — Beyond NCERT: the last was ratified in 1992).
- The Article 368 box: Parliament may, in exercise of its constituent power, amend by way of addition, variation or repeal any provision, by the procedure in the article (UPSC 2024).
- Check your progress — four student claims: the Constitution is like any other law (no — it is higher law, harder to change); change it every ten to fifteen years (no — change when needed, not by a timetable); it is a philosophy that can never change (no — it allows amendment); any talk of change is undemocratic (no — the amendment procedure is itself democratic).
2. How to amend the Constitution
The framers wanted the Constitution to be both flexible (open to change) and rigid (resistant to change): mistakes and temporary provisions should be easy to fix; the federal rights of States should not change without their consent; and core features should be protected. Hence different methods.
- The chart branches into three: like an ordinary law, by simple majority, where some articles say so; special majority in both Houses separately under Article 368; and special majority plus the legislatures of half the States, also under Article 368. We redrew it with examples.
- A boy asks whether it is really the politics of a period that makes a constitution rigid or flexible — partly yes, as the 1970s and 2001–03 show.
Simple law: many articles say Parliament may act ‘by law’ — e.g. Article 2 (admit new States) and Article 3 (increase the area of a State) — so they change without Article 368. Article 368 provides two methods: special majority of both Houses; and special majority plus consent of half the State legislatures. All amendments are initiated only in Parliament; no outside body such as a constitutional commission is needed; there is no referendum; and the President cannot send an amendment bill back for reconsideration. Thus the procedure rests on the authority of elected representatives (parliamentary sovereignty).
- The box prints the words ‘Parliament may by law’ in Article 2 (admit new States) and Article 3 (increase the area of any State) — the signal that no Article 368 procedure is needed.
- A girl asks why States cannot propose amendments — ‘another example of favouring the centre’. True, they cannot initiate (UPSC 1999, 2013); they can only ratify, and they can press their demands politically.
3. Special majority and ratification by States
Special majority: an ordinary bill passes if a simple majority of those voting support it (NCERT: 124 of 247). An amendment needs supporters who are (1) at least half the total strength of the House and (2) at least two-thirds of those actually voting, in both Houses separately, with no joint session. So a ruling party with a thin majority can pass laws and budgets, but must win some opposition support to amend the Constitution — the principle is broad consensus.
- Box: modern constitutions use special majorities (US two-thirds; South Africa and Russia three-fourths for some amendments) and people's participation (Switzerland — people can initiate; Russia and Italy among others).
- A boy groans that special majority means constant calculations — ‘is it politics or maths?’ Both: the maths forces political agreement.
- A pen portrait of Dr. Ambedkar with his words of 25 November 1949: if the dissatisfied cannot get even a two-thirds majority, their dissatisfaction cannot be taken as shared by the public. NCERT's note: behind the majority stands public opinion.
Ratification by States: for articles on the distribution of powers between the Union and States, or on representation, legislatures of half the States must pass the bill — respecting federalism. It stays practicable: only half the States, and only a simple majority in each. In short: amendment needs large-scale consensus and limited participation of the States.
- The proviso to Article 368(2) lists: Arts 54 and 55 (President's election), 73 and 162 (extent of Union and State executive power), 241 and 279A; Chapter IV of Part V (Supreme Court), Chapter V of Part VI (High Courts), Chapter I of Part XI (legislative relations); any List in the Seventh Schedule; representation of States in Parliament; and Article 368 itself (UPSC 1995).
- Not on the list: Fundamental Rights, the Election Commission (Art. 324), the Governor's conditions of office (Art. 158), or abolishing a Legislative Council (Art. 169, ordinary law).
- Key-vs-text: UPSC 2025 asked which of (I) Union List, (II) extent of a State's executive power, (III) conditions of the Governor's office need ratification; the key we hold is (d) all three. By the text of Article 368(2), I and II need ratification but Article 158 is not listed — keep the key for exam purposes, but know the text points to (a).
4. Why have there been so many amendments?
On 26 January 2024 the Constitution had completed 74 years and been amended 106 times (NCERT; the 106th, on women's reservation in legislatures, dates from 2023). NCERT's two graphs show amendments per decade and years taken for every ten amendments: the 1970s and 1980s saw the most; ten amendments came in about three years in 1974–76 (Congress dominance — 352 Lok Sabha seats) and again in 2001–03 (coalition politics and bitter rivalry). So amendments do not depend only on the size of the ruling majority; apart from the first decade, every decade has seen a steady stream.
- Graph 1 (amendments per decade, 1951–60 to 2011–18): lowest in the first decade, rising to peaks of a little over twenty in each of 1971–80 and 1981–90, then falling through the 1990s and 2000s. Graph 2 (years taken for every ten amendments, from the 10th to the 100th): short bars — about three years — for the batches that include 1974–76 and 2001–03, long ones of up to about eleven years at the start and end. We describe rather than redraw them.
- A girl asks: is something wrong with our society or Constitution? A boy answers: look at the changes, not the number.
- Technical/administrative: e.g. 15th raised High Court judges' retirement age from 60 to 62; 54th raised judges' salaries; extensions of SC/ST reserved seats every ten years (NCERT: six such amendments ‘so far’); Art. 74(1) amended to say the President shall act on ministerial advice — clarifying existing practice.
- Differing interpretations: when courts and the government read the Constitution differently — FRs vs DPSPs, the right to property, the scope of amending power — Parliament amended to assert its reading, especially in 1970–75.
- Political consensus (many after 1984): anti-defection (52nd, 91st), voting age 21→18 (61st), local bodies (73rd, 74th), reservations in jobs and admissions after 1992–93 (77th, 81st, 82nd).
- Controversial: the 38th, 39th and 42nd, made in the Emergency from June 1975. The 42nd changed the Preamble, the Seventh Schedule and 53 articles, tried to override Kesavananda, extended the Lok Sabha's term from five to six years, added Fundamental Duties and restricted judicial review — passed while many opposition MPs were in jail. After the Congress defeat in 1977, the 43rd and 44th undid most of these changes.
- ‘If there is a written constitution, where is the scope for different interpretations?’ Words like ‘law’, ‘property’ or ‘amend’ admit more than one reading, and courts must decide.
- ‘So politicians do agree on some matters — and yet fight over the meaning of what they agreed on!’ — the consensus amendments.
- ‘So it is all about politics!’ Partly; but the basic-structure section shows law also limits politics.
- Activity: the 86th Amendment (2002) made education for children aged 6–14 a Fundamental Right (Art. 21A); the 101st Amendment (2016) introduced GST and the GST Council (both Beyond NCERT details) — consensus amendments of great importance.
- Swaran Singh Committee (1976) recommended Fundamental Duties and considered giving Directive Principles precedence over Fundamental Rights (UPSC 1993). The 42nd extended Article 31C to protect laws for any Directive Principle — ‘primacy of DPSPs over FRs’ (UPSC 1979, 1981, 1986, 1989) — but Minerva Mills (1980) struck that extension down and restored balance. It also added DPSPs such as workers' participation in management (Art. 43A — UPSC 2017), equal justice and free legal aid (39A) and environment (48A), and moved education to the Concurrent List (UPSC 2006).
- 44th (1978): Lok Sabha term back to five years; ‘armed rebellion’ replaced ‘internal disturbance’ in Art. 352; Cabinet's written advice needed for an emergency; Arts 20 and 21 cannot be suspended; property ceased to be a Fundamental Right (now Art. 300A); the President may return ministerial advice once (Art. 74).
- SC/ST seat extensions: 8th (1960), 23rd (1969), 45th (1980), 62nd (1989), 79th (1999), 95th (2009) and 104th (2019) — seven, so NCERT's ‘six’ predates the 104th, which also ended nominated Anglo-Indian seats.
- The 1st Amendment (1951), under Nehru, added Article 31B and the Ninth Schedule to protect land-reform laws — the first amendment to overcome judicial readings of Fundamental Rights (UPSC 1981, 2003, 2019, 2023). The Ninth Schedule, Tenth (anti-defection, 52nd), Eleventh (73rd) and Twelfth (74th) Schedules were all added by amendments (UPSC 2005).
5. Basic structure and evolution of the Constitution
The Kesavananda Bharati ruling (1973) shaped the Constitution's evolution: (1) it set limits — no amendment can violate the basic structure; (2) within that limit Parliament can amend any and all parts; (3) the judiciary decides whether an amendment violates the basic structure and what the basic structure is. The theory appears nowhere in the text; it emerged from interpretation — the judiciary practically amended the Constitution without a formal amendment. All institutions have accepted it, and it balances rigidity (some things cannot change) and flexibility (everything else can).
Other judicial contributions: reservations generally capped at 50%; the creamy layer excluded from OBC reservations; and interpretations of the right to education, the right to life and liberty and minority educational institutions — informal amendments through interpretation.
- Shankari Prasad (1951) and Sajjan Singh (1965): Parliament can amend Fundamental Rights. Golaknath (1967), 11 judges: it cannot. The 24th Amendment (1971) restored the power and made Presidential assent obligatory.
- Kesavananda Bharati, decided 24 April 1973 by 13 judges (7:6): Parliament can amend any part but not the basic structure (UPSC 1981, 1985, 1994). Indira Gandhi v. Raj Narain (1975) applied it to strike down part of the 39th Amendment. Minerva Mills (1980): limited amending power and the balance between FRs and DPSPs are themselves basic.
- Indra Sawhney (1992): creamy layer and the 50% norm; the 103rd Amendment's 10% EWS quota was upheld in Janhit Abhiyan (2022).
- The National Commission to Review the Working of the Constitution was set up in 2000 under Justice M.N. Venkatachaliah and reported in 2002.
- ‘So it is the judiciary that has the final word — is this judicial activism?’ It is judicial review of amendments; activism is a broader debate.
- The box: in 2000 the Government appointed a commission to review the working of the Constitution under retired Chief Justice Venkatachaliah; opposition parties boycotted it, but it stayed within the basic structure.
- ‘It's all wrong — first consensus, now judges change the meaning!’ NCERT's answer comes in the next section: the courts protected the spirit of the Constitution.
6. The Constitution as a living document
Like a living being, the Constitution responds to experience: dynamic, open to interpretation, responsive to new situations — the answer to the riddle of its durability, and why citizens respect it. The recurring constitutional question since 1950 has been the supremacy of Parliament: as the people's representative it should have the upper hand, but within the framework of the Constitution, because democracy is also about the rule of law, institutions and balance.
Contribution of the judiciary: Parliament claimed the power to make laws and amendments for the poor and needy; the judiciary insisted that even good intentions must work within constitutional procedures, since bypassing law invites arbitrary power. In Kesavananda the Court turned to the spirit rather than the letter — the basic structure is an ‘invention’ of the judiciary, grounded in the intent and social aspirations behind the text.
Maturity of political leadership: after the fierce 1967–73 controversy, attempts to have the Court reconsider Kesavananda failed; the 42nd asserted parliamentary supremacy; the Court reaffirmed its stand in Minerva Mills (1980). Since then parties, governments and Parliament have accepted the inviolable basic structure — even the review exercise stayed within it. The shared vision of the national movement — Nehru's ‘tryst with destiny’: dignity and freedom of the individual, social and economic equality, well-being of all, national unity — keeps the Constitution respected.
- ‘Is it a see-saw or a tug of war?’ — the balance between Parliament and the judiciary: at its best a see-saw that stays level; in the 1970s, a tug of war.
- ‘Let us not ignore instances of political immaturity’ — e.g. the Emergency amendments.
- ‘Without rights and elections the Constitution makes no sense; without well-being, rights and elections make no sense — is this the spirit?’ Yes: liberty, democracy and welfare together.
Conclusion (NCERT): debates about the basic structure are healthy; democracy needs debate but also compromise and a common minimum ground. Organs of government will compete over importance and over what serves the people's welfare, but the final authority lies with the people.
- An amendment bill can start in either House, never in a State legislature, and needs no prior Presidential recommendation (UPSC 1999, 2013; 2022 in Chapter 5).
- Ratification is by half the States, not all, and by simple majority in each (UPSC 2013).
- The President must assent to an amendment bill — there is no suspensive veto here.
- Changing State boundaries or creating a State is not an Article 368 amendment (Art. 4).
- The basic structure is not defined in the Constitution, and there is no exhaustive judicial list.
- Ninth Schedule laws added after 24 April 1973 are open to judicial review (UPSC 2018).
- The 44th, not the 42nd, removed the right to property from Fundamental Rights.

What to remember
Numbers
One-liners
- Indian Constitution = partly flexible, partly rigid.
- Only Parliament initiates amendments; no referendum.
- Behind the special majority stands public opinion (Ambedkar).
- Count the changes, not the number of amendments.
- 38th, 39th, 42nd: controversial; 43rd, 44th: correction.
- Basic structure: everything amendable except the core; courts decide the core.
- Spirit over letter — Kesavananda.
- Final authority lies with the people.
Traps to avoid
- Amendment bills cannot start in State legislatures, and the President cannot initiate them.
- Ratification needs half the States, not all.
- The President must assent to an amendment bill.
- Creating States and changing boundaries need only a simple majority (Arts 3–4).
- Golaknath (1967) said FRs cannot be amended; Kesavananda (1973) said they can, but not the basic structure.
- The 42nd gave DPSPs primacy; Minerva Mills (1980) undid that.
- The 44th, not the 42nd, removed property from Fundamental Rights.
- Ninth Schedule laws are not fully immune — post-24 April 1973 additions are reviewable.
- NCERT's 545-member Lok Sabha is now 543 after the 104th Amendment.
How to strategise
Prelims — what UPSC asks
- Procedure: Article 368 ‘addition, variation, repeal’ (2024), initiation (1999, 2013), ratification lists (1995, 2025 — note the key-vs-text issue), schedules added by amendments (2005).
- 42nd and DPSP primacy: 1979, 1981, 1986, 1989, Art. 43A (2017), Swaran Singh (1993), RTE and education (2006).
- Basic structure and Ninth Schedule: Kesavananda (1981, 1985), meaning of basic structure (1994), Art. 31B and Ninth Schedule (1981, 2003, 2018, 2019), 1st Amendment vs courts (2023).
Mains — where it appears and how to answer
- GS2 — amending power: Supreme Court's check on Parliament's amending power (2013), limited vs absolute amending power under Article 368 (2019), procedural and substantive limits (2025).
- GS2 — consensus amendments: the 101st (GST) Amendment (2017).
- Answer frame: Article 368 design (flexible + rigid; consensus; federal ratification) → history (Shankari Prasad → Golaknath → 24th → Kesavananda → 42nd → Minerva Mills → Coelho) → basic structure as balance → criticism (judge-made, uncertain list) → conclusion: a living document anchored in constitutional supremacy.
