Why a living document?
The Constitution was made in 1949, but society, technology and needs keep changing. A constitution that can never change would break; one that changes too easily would lose its value. India's Constitution is a balance of rigidity and flexibility. It changes through amendments (formal changes by Parliament) and through judicial interpretation (courts reading it in new ways), and through political practice. Because it grows while keeping its core, it is called a living document.
How is the Constitution amended?
Article 368 gives the procedure. Only Parliament can start an amendment; there is no referendum and no separate body.
- Simple majority (like an ordinary law; not counted as an amendment under Article 368): for example creating new states or changing names and boundaries (Article 3), citizenship rules, the number of Supreme Court judges.
- Special majority in each house separately: (a) a majority of the total membership of the house and (b) two-thirds of members present and voting. Most parts, including fundamental rights and Directive Principles, change this way.
- Special majority + ratification by at least half of the state legislatures (by simple majority): for federal parts such as the division of powers between Union and states, representation of states in Parliament, the Supreme Court and High Courts, and the election of the President.
The President must give assent; there is no veto. A joint sitting cannot be used.
Working out a special majority
Lok Sabha total strength = 543. Rule (a): more than half of 543 = at least 272. Rule (b): two-thirds of those present and voting.
- If 500 are present and voting: 2/3 Γ 500 = 333.3 β at least 334. Both rules must hold, so 334 yes votes are needed.
- If only 390 are present and voting: 2/3 Γ 390 = 260. But rule (a) needs 272, so 272 yes votes are needed.
So the required number = the larger of 272 and two-thirds of those present (rounded up).
Why have there been so many amendments?
More than 100 amendments have been made since 1950. That sounds like a lot, but most are small:
- Technical or administrative changes: for example the 15th Amendment raised the retirement age of High Court judges from 60 to 62; salary and pension details.
- Different interpretations: Parliament and the courts disagreed, for example on land reform and property rights, and Parliament passed amendments to overcome court rulings.
- Political consensus: many amendments had support from almost all parties, such as the 52nd (anti-defection, 1985), 61st (voting age 21 β 18, 1989), 73rd and 74th (panchayats and municipalities, 1992).
Controversial amendments: between 1970 and 1990, some amendments were debated heavily. The 42nd Amendment (1976), passed during the Emergency, tried to limit judicial review and extend Parliament's term. The 44th Amendment (1978) reversed many of those changes.
Basic structure and the evolution of the Constitution
Can Parliament change anything at all? In the Kesavananda Bharati case (1973), the Supreme Court said: Parliament can amend any part of the Constitution, but it cannot damage its basic structure. The court did not give a full list, but it has included the supremacy of the Constitution, democracy and free elections, the republican form, secularism, federalism, separation of powers, judicial review, independence of the judiciary and core fundamental rights.
In the Minerva Mills case (1980), the court struck down parts of the 42nd Amendment that tried to make amendments unquestionable. The basic structure doctrine is itself an example of the Constitution evolving through judicial interpretation. It balances change with continuity: the Constitution can grow, but its spirit is protected.
Try it: pass an amendment
Take your class of, say, 40 students as a 'house'. On a day when 33 are present and all vote, how many yes votes does a special majority need? (Rule a: more than half of 40 = 21. Rule b: 2/3 of 33 = 22.) The answer is 22. Now try the sliders in the last 3D step for the Lok Sabha.
Key formulas and definitions
- Article 368: procedure for amendment; only Parliament starts it
- Special majority = majority of total membership AND 2/3 of members present and voting (in each house)
- Lok Sabha: required yes votes = max(272, β2/3 Γ present and votingβ)
- Federal provisions: special majority + at least half of the states
- Basic structure: Kesavananda Bharati (1973); Minerva Mills (1980)
- Key amendments: 42nd (1976), 44th (1978), 52nd (1985), 61st (1989), 73rd & 74th (1992)
Worked examples
1. Lok Sabha: 450 members present and voting. How many yes votes are needed for a special majority?
Rule (a): 272. Rule (b): 2/3 Γ 450 = 300. Larger = 300 yes votes.
2. Lok Sabha: 360 present and voting. How many yes votes?
Rule (b): 2/3 Γ 360 = 240. Rule (a): 272. Larger = 272 yes votes.
3. Rajya Sabha has 245 members; 210 present and voting. How many yes votes?
Rule (a): more than half of 245 = 123. Rule (b): 2/3 Γ 210 = 140. Larger = 140.
4. An amendment changes how seats in the Rajya Sabha are shared among states. There are 28 states. At least how many state legislatures must approve?
At least half of 28 = 14 states, besides a special majority in both houses.
5. A proposed amendment says 'elections are cancelled for 20 years'. Could it survive in court?
No. Democracy and free elections are part of the basic structure, so the Supreme Court would strike it down.
6. Which type of majority is needed to create a new state?
A simple majority in Parliament (Article 3), after consulting the state concerned. It is not an amendment under Article 368.
Common mistakes
- Thinking a special majority is just two-thirds of those present. It also needs a majority of the total membership.
- Thinking all amendments need state approval. Only federal provisions do.
- Saying Parliament can change anything. It cannot destroy the basic structure.
- Thinking the President can refuse to sign a constitutional amendment. The President must give assent.
