📖 Detailed Notes
Written and reviewed by Subhra Gupta, Humanities faculty at UniDrill (M.A. Sociology, University of Delhi · 7 years teaching Humanities). Based on NCERT Political Science Class XI (Indian Constitution at Work), Chapter 9.
Why has one Constitution lasted since 1950?
The Soviet Union had four constitutions in its lifetime (1918, 1924, 1936 and 1977). France has had five republics, each with a fresh constitution, the latest dating from 1958. Russia wrote a new one in 1993 after the Soviet break-up. India has worked with the same Constitution since 26 January 1950.
The surprise is that it has lasted because it can change. The framers knew that a constitution could not be a static document, so they built a way to amend it. Political practice and court rulings then gave it more flexibility. That is what "a living document" means: a Constitution that responds to changing needs instead of staying a closed, frozen rulebook.
Why it matters. The framers faced a real tension. A Constitution must be treated as sacred and placed above ordinary law, or it protects nothing. But if it can never be changed, it breaks when society changes. The amendment procedure is their solution: hard enough to protect the core, easy enough to avoid a crisis.
| Type | Meaning | Risk |
|---|---|---|
| Flexible constitution | Can be changed very easily | May be altered to suit whoever is in power |
| Rigid constitution | Very difficult to amend | May break or be ignored when society changes |
| India's design | Amendable by Parliament under Article 368 with demanding majorities, plus the courts' check | Balance between the two |
How is the Constitution amended?
Article 368 lets Parliament, using its constituent power, amend the Constitution by addition, variation or repeal of any provision, following the procedure the Constitution lays down. There are three routes.
| Route | Used for | What is needed | Example |
|---|---|---|---|
| First: like an ordinary law | Articles that say "by law" | Simple majority in Parliament. These changes are not even counted as constitutional amendments | Article 2 (admission of new States), Article 3 (names and boundaries of States) |
| Second: special majority | Most of the Constitution, including Fundamental Rights | Special majority in each House, passed separately | Freedom of religion, the Election Commission |
| Third: special majority plus ratification | Provisions affecting the federal balance, such as the Union List | Special majority, then approval by the legislatures of at least half the States | Changes to the Union List |
The special majority is a double test, and both parts must be met in the same vote: those in favour must be at least half of the total strength of the House and two-thirds of those present and voting. Each House votes separately, and there is no joint sitting to break a deadlock. For ratification, half the State legislatures must approve, each by a simple majority.
Pause and predict: the Lok Sabha has 543 members. If all seats are filled and 400 members are present and vote, what is the minimum number of votes needed for an amendment?
Check your answer: 272. Two-thirds of 400 is 267, but at least half of the total strength (543) is 272, and the bigger of the two numbers binds. If 450 were voting, two-thirds would be 300, and then that part would be the binding one.
Three more rules protect the procedure.
| Rule | What it means |
|---|---|
| No outside agency | No commission or referendum is involved; only the elected representatives decide. This is parliamentary sovereignty applied to constitutional change |
| Bills start in Parliament | An amendment bill cannot be introduced in a State legislature |
| President's role | The President must give assent and cannot send an amendment bill back for reconsideration |
Beyond the textbook. For the exam: the President must assent to an amendment bill and cannot return it. In reality: the 24th Amendment (1971) wrote this rule in explicitly, so that assent is compulsory. Ordinary bills can be returned once for reconsideration; amendment bills cannot, which keeps the final decision with the elected Houses.
Here is how the routes apply to five subjects the chapter asks you to classify.
| Subject of change | Route needed |
|---|---|
| Citizenship rules | Ordinary law (simple majority), as Parliament regulates citizenship by law |
| Freedom of religion | Special majority only |
| Union List | Special majority plus ratification by half the States |
| State boundaries | Ordinary law (Article 3) |
| Election Commission | Special majority only |
Pause and predict: a bill to change the powers of the States passes both Houses by a special majority. Is it now law?
Check your answer: not yet. Because it affects the federal balance, half the State legislatures must also approve it by simple majority. Only then does it go to the President for assent.
Two bursts of amendments: what the pattern shows
By 26 January 2024 the Constitution had been amended 106 times in 74 years. The graph of amendments has two sharp spikes, each with about ten amendments in three years: 1974 to 1976 and 2001 to 2003. In the first, one party held a large majority and the Emergency was in force. In the second, coalition governments were in power. Amendments, then, are not simply a product of a single party's majority; they happen under very different political conditions.
Two views. For the exam: the large number of amendments shows that the Constitution is flexible and adapts to changing needs. Another reading: some scholars read the same record more cautiously. The spike of 1974 to 1976 shows how quickly the text can be changed when one party holds a large majority, which is why they treat the courts' basic structure limit as an essential check on the amending power.
Three kinds of amendment
Amendments fall into three groups, depending on how they came about.
| Kind | What it is | Examples |
|---|---|---|
| Technical or administrative | Clarifications with little controversy | 15th Amendment (retirement age of High Court judges raised from 60 to 62); 54th (judges' salaries); six amendments extending SC and ST reservation in legislatures; the clarification that the Council of Ministers' advice under Article 74(1) binds the President |
| Differences of interpretation | Parliament and the judiciary read provisions differently, so the Constitution is amended to settle it | Clashes between 1970 and 1975 over Fundamental Rights versus Directive Principles, the right to property, and the limits of Parliament's amending power |
| Political consensus | Parties agreed across ideological lines | 52nd (1985) and 91st (2003) on anti-defection; 61st (1988) lowering the voting age from 21 to 18; 73rd and 74th (1992) on Panchayats and municipalities; 77th, 81st and 82nd on reservations |
The 91st Amendment also capped the Council of Ministers at 15 per cent of the strength of the House. A separate set of amendments, 38th, 39th and 42nd, were enacted during the Emergency and are listed as controversial.
The Emergency amendments and the 42nd Amendment
The Emergency was declared in June 1975. The 38th, 39th and 42nd Amendments were passed in that background. The 42nd Amendment (1976) is the widest: it extended the Lok Sabha's term from five years to six, inserted Fundamental Duties, restricted judicial review, made changes to the Preamble and the Seventh Schedule, and changed 53 articles. It was described as practically a rewriting of many parts of the original Constitution, and it tried to override the basic structure ruling.
After the 1977 elections, the new government reversed the most controversial changes through the 43rd (1977) and 44th (1978) Amendments. The 44th Amendment restored the five-year Lok Sabha term.
The chain in one line: Emergency (June 1975) → 42nd Amendment (1976) → 1977 election → 43rd and 44th Amendments reverse its excesses.
The basic structure doctrine
In Kesavananda Bharati (1973) the Supreme Court gave a ruling that the chapter calls perhaps the most important development in India's constitutional history. It made three contributions.
| Contribution | Meaning |
|---|---|
| A limit | Parliament cannot make an amendment that violates the basic structure of the Constitution |
| Freedom within the limit | Parliament can amend any and every part of the Constitution, so long as the basic structure stays intact |
| Final word | The judiciary decides what counts as the basic structure |
Why it works this way. The Constitution does not contain the words "basic structure". The doctrine is a judicial innovation drawn from the spirit rather than the letter of the Constitution. It answers a worry that a temporary majority might use the amending power to destroy the very values the Constitution protects. The Court has not given a closed list; it identifies basic features case by case.
When the 42nd Amendment tried to override the doctrine, the Supreme Court reaffirmed it in Minerva Mills (1980). Since then political parties have accepted that the basic structure is inviolable. Even the National Commission to Review the Working of the Constitution (the Venkatachaliah Commission, set up in 2000) kept to the basic structure and did not recommend dropping it. Some parties and groups had stayed away from the Commission because they feared it would lead to rewriting the Constitution.
Pause and predict: if Parliament can amend any part of the Constitution, why can it not abolish the basic structure?
Check your answer: because the power to amend is limited by the doctrine. Parliament may change any provision, but not in a way that destroys the basic structure. The Court, not Parliament, has the final say on what that structure is.
Two views. For the exam: the basic structure doctrine balances rigidity and flexibility: Parliament can amend widely, but not destroy the Constitution's core. Another reading: supporters value it as a safeguard that outlasts any temporary majority, especially after the Emergency experience. Critics argue that, because the doctrine is not in the text, a few judges decide the limits of the power of an elected Parliament. The chapter itself calls it a judicial innovation, and the Minerva Mills ruling and the Commission's decision show that the doctrine has become accepted.
Judges can amend without amending
The meaning of the Constitution has also grown through interpretation, without any change to its words. Examples include the 50 per cent cap on reservations, the creamy layer exclusion for Other Backward Classes, and broader readings of the right to education, the right to life and liberty and the rights of minority educational institutions. This is why the Constitution is called a living document: it responds to experience, balances letter and spirit, and survives through political maturity and a shared vision. That vision, in Nehru's "tryst with destiny" address to the Constituent Assembly, was dignity and freedom for the individual, social and economic equality, well-being, national unity and a contribution to world peace.

| 2000 | Venkatachaliah Commission set up | Kept to the basic structure |
| 2003 | 91st Amendment | Further anti-defection provisions; 15 per cent cap on the Council of Ministers |
Exam traps
| The trap | Why it is tempting | The truth |
|---|---|---|
| "A special majority means two-thirds of the House." | Two-thirds is the part everyone remembers | Two-thirds of those present and voting and at least half of the total strength |
| "States must ratify by a special majority." | The same phrase seems to apply everywhere | Each State legislature needs only a simple majority; and only half of the States need to act |
| "The President can return an amendment bill." | The President can return an ordinary bill | For an amendment bill the President must assent |
| "Parliament holds a joint sitting, or a referendum is held, to settle deadlock." | Other countries use referendums | Both Houses pass the bill separately; there is no joint sitting and no referendum |
| "Basic structure is written in the Constitution." | It sounds like an article | It is a judicial doctrine from Kesavananda Bharati (1973), reaffirmed in Minerva Mills (1980) |
| "The 44th Amendment was the controversial one." | The two numbers are close | The 42nd (1976) was controversial; the 43rd and 44th rolled back its excesses |
| "Anti-defection is the 42nd Amendment, voting age the 91st." | Numbers are easy to mix up | Anti-defection is the 52nd and 91st; the voting age was lowered by the 61st |
| "The Venkatachaliah Commission recommended dropping the basic structure." | It was set up to review the Constitution | It kept to the basic structure |

Q7. Which of the following changes would need ratification by the legislatures of at least half the States, in addition to a special majority in Parliament?
▸ Show answer & explanation
Answer: C
The Union List affects the federal balance, so State ratification is needed. Citizenship and Article 3 matters are handled by ordinary law, and the Election Commission needs only a special majority.
Q8. Assertion (A): No outside agency such as a constitutional commission or a referendum is required to amend the Constitution. Reason (R): Only the elected representatives of the people can finally decide on changes to the Constitution.
▸ Show answer & explanation
Answer: A
The absence of an outside agency follows from the principle that elected representatives alone decide amendments, so R explains A.
Q9. The Minerva Mills case (1980) is significant because it:
▸ Show answer & explanation
Answer: B
Minerva Mills confirmed the basic structure doctrine and political parties have since accepted it. The other options describe things the Court did not do.
Q10. The Lok Sabha has 543 members, all seats are filled, and 400 members are present and vote on an amendment bill. What is the minimum number of votes in favour needed to meet the special majority?
▸ Show answer & explanation
Answer: B
Two-thirds of the 400 voting is 267, but at least half of the total strength of 543 is 272, and both conditions must be met, so 272 is the minimum. 267 meets only one test, and 362 is two-thirds of 543, a test the Constitution does not apply.
Q11. Which pair is correctly matched?
▸ Show answer & explanation
Answer: B
The 73rd gave constitutional status to Panchayats. The 61st lowered the voting age, the 91st dealt with anti-defection and the Council of Ministers cap, and the anti-defection law began with the 52nd, not the 42nd.
Q12. Which statement about the basic structure doctrine is correct?
▸ Show answer & explanation
Answer: B
The doctrine came from the Kesavananda Bharati judgment. It limits the amending power but still allows wide amendments. A is wrong because it is a judicial doctrine, C overstates the limit, and D is wrong because the 42nd Amendment tried to override it.
