Article 368 is one of those provisions that UPSC loves to test repeatedly — but the way they test it changes dramatically based on difficulty. I have seen aspirants who know the basics still get tripped up because the examiner frames the question at a level they did not prepare for.
In this piece, I will walk you through the entire amendment process from scratch, and then show you exactly how UPSC frames questions at three distinct difficulty levels — basic, intermediate, and advanced. By the end, you will know not just the process, but how to think like the examiner.
Where This Topic Sits in the UPSC Syllabus
| Exam Stage | Paper | Syllabus Section |
|---|---|---|
| Prelims | General Studies | Indian Polity — Constitution, amendments, significant provisions |
| Mains | GS-II | Indian Constitution — amendments, basic structure, federal issues |
This topic connects directly to federalism, judicial review, basic structure doctrine, and separation of powers. UPSC has asked questions on this at least 8-10 times across Prelims and Mains since 2000.
Understanding the Amendment Process — The Foundation
Article 368 of the Constitution gives Parliament the power to amend the Constitution. But unlike ordinary laws, amendments follow a special procedure. K.C. Wheare called the Indian Constitution “quasi-federal” partly because of this flexible-yet-rigid amendment process.
There are three types of amendments based on the majority required:
Type 1 — Simple Majority: Some provisions can be changed by a simple majority in Parliament, just like an ordinary law. These are not technically considered amendments under Article 368. Examples include admission of new states (Article 2), creation of new states (Article 3), and changes to citizenship laws.
Type 2 — Special Majority: Most constitutional amendments require a special majority — a majority of the total membership of each House AND a two-thirds majority of members present and voting. This covers fundamental rights, DPSPs, and most other provisions.
Type 3 — Special Majority + State Ratification: Certain provisions that affect the federal structure need approval by at least half the state legislatures in addition to the special majority. This applies to election of the President, distribution of legislative powers, representation of states in Parliament, Article 368 itself, and similar provisions.
The Step-by-Step Procedure
An amendment bill can be introduced in either House of Parliament — Lok Sabha or Rajya Sabha. No prior permission of the President is needed. The bill must be passed in each House separately with the required majority. There is no provision for a joint sitting if the two Houses disagree on an amendment bill. This is a favourite UPSC trap.
Once both Houses pass the bill, it goes to the President. After the 24th Amendment (1971), the President is obliged to give assent. There is no discretion here.
The Basic Structure Doctrine — The Invisible Limit
The Kesavananda Bharati case (1973) established that Parliament can amend any part of the Constitution, but cannot destroy its basic structure. The Supreme Court did not give a complete list of what constitutes basic structure. Over time, through various cases, the following have been identified as part of it:
- Supremacy of the Constitution
- Republican and democratic form of government
- Secular character of the Constitution
- Separation of powers
- Federal character
- Judicial review
- Rule of law
The 42nd Amendment (1976) tried to remove judicial review of amendments. The Supreme Court struck this down in Minerva Mills v. Union of India (1980), reaffirming the basic structure doctrine.
Level 1 — How UPSC Tests at Basic Difficulty
At the easiest level, UPSC asks straightforward factual questions. For example: “Which of the following amendments require ratification by states?” or “Can an amendment bill be introduced in Rajya Sabha?” These test whether you have read the bare provision. Most aspirants who study from a standard Polity textbook can handle this level.
The trick here is precision. Know that joint sitting does not apply. Know that the President must give assent. Know the difference between simple and special majority.
Level 2 — Intermediate Difficulty
Here, UPSC combines amendment procedure with related concepts. A typical question might list four statements mixing amendment types with specific articles and ask which combination is correct. Or they might ask about which specific amendments changed Article 368 itself.
At this level, you need to know specific amendments — the 24th, 42nd, and their context. You also need to connect the amendment process to the federal structure. For Mains, a question like “Discuss whether the amendment process adequately protects the interests of states” tests your analytical ability.
Level 3 — Advanced Difficulty
This is where UPSC separates toppers from the rest. Advanced questions link the amendment process to the basic structure doctrine, judicial decisions, and comparative constitutional law. A Mains question might ask: “The basic structure doctrine is a judicial innovation that limits parliamentary sovereignty. Critically examine.”
To handle this level, you need to know the evolution from Shankari Prasad (1951) to Golaknath (1967) to Kesavananda Bharati (1973) to Minerva Mills (1980). You need to understand the tension between parliamentary supremacy and judicial review. You should be able to argue both sides.
Previous Year UPSC Questions on This Topic
Q1. Which of the following amendments to the Constitution of India made it obligatory for the President to give assent to a Constitutional Amendment Bill?
(UPSC Prelims — GS)
Answer: The 24th Amendment (1971). Before this, there was ambiguity about whether the President could withhold assent. The 24th Amendment clarified that the President “shall” give assent, removing any discretion.
Q2. Discuss the significance of the basic structure doctrine in limiting the amending power of Parliament.
(UPSC Mains — GS-II)
Answer: The basic structure doctrine, established in Kesavananda Bharati (1973), holds that Parliament can amend any provision but cannot alter the Constitution’s fundamental identity. This includes federalism, secularism, judicial review, and rule of law. The doctrine balances flexibility with permanence — allowing change while protecting core values. Without it, a temporary majority could fundamentally alter the Constitution’s character. Critics argue it gives unelected judges veto power over elected representatives. However, the doctrine has served as a crucial check, especially during the Emergency period when the 42nd Amendment attempted sweeping changes.
Q3. A Constitutional Amendment Bill requires a joint sitting of Parliament if the two Houses disagree. Evaluate this statement.
(UPSC Prelims — GS)
Answer: This statement is incorrect. Article 108 provides for joint sittings only for ordinary bills. Constitutional amendment bills must be passed by each House separately. If one House rejects the bill, the amendment fails. This makes the amendment process more rigid and gives Rajya Sabha an effective veto — a point that connects to India’s federal design.
Key Points to Remember for UPSC
- Article 368 provides the amendment procedure but does not cover amendments passable by simple majority — those fall outside its scope.
- No joint sitting is possible for amendment bills — each House must pass independently.
- After the 24th Amendment, Presidential assent is mandatory with no discretion.
- Ratification by half the states is needed only for provisions affecting the federal structure.
- The basic structure doctrine has no fixed list — it evolves through judicial interpretation.
- The journey from Shankari Prasad to Minerva Mills defines the limits of amending power.
- The 42nd Amendment is the most tested amendment in UPSC — know its provisions and what was struck down.
Understanding the amendment process deeply gives you an edge across multiple questions in both Prelims and Mains. As a next step, I recommend reading the Kesavananda Bharati judgment summary from any standard Polity source and making a timeline chart of all landmark cases on Article 368. This single exercise will prepare you for all three difficulty levels that UPSC throws at you.
