2. The Basic Structure Doctrine (basic)
Imagine the Constitution as a grand building. While you can certainly repaint the walls or upgrade the plumbing to keep up with the times, you cannot remove the foundation or the load-bearing pillars without causing the entire structure to collapse. This is exactly what the Basic Structure Doctrine represents in Indian Constitutional law. It is a judicial principle which dictates that while Parliament has the power to amend the Constitution under Article 368, it cannot alter or destroy those essential features that constitute its core identity.
This doctrine didn't appear overnight; it emerged from a long "tug-of-war" between the Parliament and the Judiciary. Initially, the Supreme Court held that Parliament could amend any part of the Constitution. However, in the Golak Nath case (1967), the Court took a sharp turn, stating that Fundamental Rights were "transcendental" and beyond the reach of Parliament's amending power Indian Polity, Landmark Judgements and Their Impact, p.645. This conflict finally reached a climax in the landmark Kesavananda Bharati vs. State of Kerala (1973) case. In a 7:6 verdict, the Supreme Court ruled that while Parliament can indeed amend Fundamental Rights, it cannot touch the "basic structure" of the Constitution Politics in India since Independence, The Crisis of Democratic Order, p.97.
1951: Shankari Prasad Case — Court rules Parliament can amend Fundamental Rights.
1967: Golak Nath Case — Court rules Fundamental Rights are sacrosanct and cannot be amended.
1973: Kesavananda Bharati Case — The birth of the "Basic Structure Doctrine."
1980: Minerva Mills Case — Reaffirmed that Judicial Review is part of the basic structure.
What exactly qualifies as "Basic Structure"? Interestingly, the Supreme Court has never provided an exhaustive list. Instead, it decides whether a feature is "basic" on a case-by-case basis Indian Constitution at Work, CONSTITUTION AS A LIVING DOCUMENT, p.213. Over the years, features like Secularism, Federalism, Democracy, the Rule of Law, and Judicial Review have been recognized as part of this bedrock. This makes the Judiciary the final gatekeeper of constitutional integrity, ensuring that the "spirit" of the Constitution survives even if its "letter" is changed.
Key Takeaway The Basic Structure Doctrine ensures that Parliament's power to amend the Constitution does not turn into the power to destroy it; the core identity of the Constitution is legally unchangeable.

3. Understanding Types of Majorities in Parliament (intermediate)
To understand how the Constitution is amended, we must first master the
'math of democracy'—the different types of majorities required in Parliament. Think of these as different hurdles of varying heights: some are easy to jump (Simple Majority), while others require an extraordinary effort (Special Majority). The Constitution uses these different thresholds to ensure that while routine laws are easy to pass, fundamental changes to our governance structure require broad consensus.
Most daily business in Parliament, such as passing Ordinary or Money Bills, requires a Simple Majority. This simply means more than 50% of the members present and voting. However, for more sensitive roles, we use the Effective Majority, which is a majority of the 'effective strength' (Total seats minus Vacancies). For example, if the Rajya Sabha has 245 seats but 5 are vacant, the effective strength is 240, and the majority needed is 121. This is specifically required for removing the Vice-President or the Speaker Indian Polity, M. Laxmikanth, Parliament, p.240.
When it comes to the Amendment of the Constitution (Article 368), the hurdle is much higher. We use a Special Majority which must satisfy two conditions simultaneously: (1) more than 50% of the total membership of the House, and (2) at least two-thirds of the members present and voting. This ensures that a thin attendance cannot be used to force through a constitutional change Indian Constitution at Work, Class XI NCERT, Election and Representation, p.69.
| Majority Type |
Definition |
Key Usage |
| Simple |
> 50% of those Present & Voting |
Ordinary Bills, Confidence Motion |
| Effective |
> 50% of (Total Strength - Vacancies) |
Removal of VP (RS), Speaker (LS) |
| Special (Art. 368) |
> 50% of Total + 2/3rd of Present & Voting |
Constitutional Amendments, SC/HC Judge Removal |
| Special (Art. 61) |
2/3rd of Total Membership |
Impeachment of the President |
Key Takeaway While most laws need only a simple majority of those present, constitutional amendments under Article 368 require a 'double-lock' Special Majority: half of the total house strength AND two-thirds of those actually voting.

4. Constitutional Amendment vs. Ordinary Legislation (intermediate)
To understand the Indian Constitution, one must distinguish between
Ordinary Legislation (the laws that govern our daily lives) and
Constitutional Amendments (changes to the supreme law of the land). While both follow a legislative path, the Constitution establishes a much higher 'bar' for amendments to ensure the foundational framework isn't changed on a whim. Unlike some countries where the executive has more control, in India, a Constitutional Amendment Bill can be initiated by
any member (Minister or Private Member) in
either House of Parliament—the Lok Sabha or the Rajya Sabha
Laxmikanth, M. Indian Polity, Chapter 11, p. 123. Unlike Money Bills, these do not require the prior recommendation of the President for introduction
Laxmikanth, M. Indian Polity, Chapter 11, p. 123.
The most critical distinction lies in the passage of the Bill. For ordinary laws, if the two Houses disagree, the President can summon a Joint Sitting under Article 108 to break the deadlock. However, for a Constitutional Amendment, Article 368(2) strictly mandates that the Bill must be passed in each House separately by a Special Majority (a majority of the total membership and two-thirds of those present and voting). If one House rejects the Bill, it simply dies; there is no provision for a joint sitting to rescue it D. D. Basu, Introduction to the Constitution of India, Chapter 12, p. 257. This ensures that the Rajya Sabha, representing the states, holds an equal and veto-like power over changes to the Constitution.

Finally, when an amendment affects the federal structure (like the election of the President or the powers of the Supreme Court), it requires an extra step: ratification by the legislatures of at least one-half of the states by a simple majority Laxmikanth, M. Indian Polity, Chapter 11, p. 123. It is a common misconception that all states must agree; the threshold is strictly 50%.
Key Takeaway Constitutional Amendments require a Special Majority in each House separately; the deadlock-breaking mechanism of a Joint Sitting is strictly prohibited for these Bills.

5. Amendments Outside the Scope of Article 368 (intermediate)
When we talk about amending the Constitution, we usually think of the rigorous process under Article 368. However, the Indian Constitution is unique because it allows for a high degree of flexibility. Certain provisions can be changed through a Simple Majority of Parliament—the same way an ordinary law is passed. The most critical point for you to remember is that although these changes technically alter the text or schedules of the Constitution, they are not deemed to be amendments under Article 368 Laxmikanth, M. Indian Polity, Amendment of the Constitution, p.124.
This "side door" exists for matters that are administrative or transitional in nature, where the framers didn't want the Parliament to be tied down by rigid voting requirements. For instance, if the Parliament wants to admit a new state into the Union or change the boundary of an existing state (under Articles 2 and 3), it can do so by a simple majority. Article 4 specifically declares that such laws are not to be considered amendments for the purposes of Article 368 Laxmikanth, M. Indian Polity, Union and Its Territory, p.60. This allows the internal map of India to be reorganized without the hurdles of a Special Majority.
Beyond state boundaries, several other provisions fall into this category. Here is a comparison of how these two "paths" of change differ:
| Feature |
Amendments under Art. 368 |
Amendments outside Art. 368 |
| Majority Required |
Special Majority (2/3rd present & voting + absolute majority) |
Simple Majority (more than 50% of those present and voting) |
| Scope |
Fundamental Rights, DPSP, Federal structure, etc. |
Admission of states, salaries of judges, quorum, citizenship, etc. |
| Classification |
Constitutional Amendment Bill |
Ordinary Legislative Process |
Other examples of changes made by a simple majority include the abolition or creation of Legislative Councils in states, the salaries and allowances of the President and Governors (Second Schedule), and rules of procedure in Parliament Laxmikanth, M. Indian Polity, Amendment of the Constitution, p.124. By keeping these items outside the scope of Article 368, the Constitution maintains a balance between being a "sacred" document and a "living" document that can adapt to routine governance needs.
Key Takeaway Provisions changed by a Simple Majority (like reorganizing states or changing salaries) are legally valid changes to the Constitution but are NOT technically "amendments" as defined by Article 368.

6. Federalism and State Participation in Governance (intermediate)
In a federal setup like India’s, the Constitution is not just a document for the Central government; it is a compact that defines the powers of both the Union and the States. To ensure the Union doesn't unilaterally change the rules of the game, our Constitution provides for State participation in the amendment process. This reflects the principle of rigidity in a federal system, ensuring that the 'division of powers' cannot be easily disturbed Indian Polity, Salient Features of the Constitution, p.29.
While the Parliament has the primary power to amend, it is important to remember that for amendments, the Lok Sabha and Rajya Sabha stand on equal footing. Unlike Money Bills, which only the Lok Sabha can control Indian Constitution at Work, LEGISLATURE, p.110, a Constitutional Amendment Bill can be initiated in either House of Parliament. This ensures that the Rajya Sabha, which represents the States of the Indian Union, has an equal say in protecting state interests Indian Polity, Parliament, p.259.
When an amendment seeks to change the federal character of the Constitution (such as the election of the President, the distribution of legislative powers between the Union and States, or the representation of states in Parliament), a special safeguard is triggered. Under Article 368, such a bill must not only be passed by both Houses of Parliament with a special majority but also be ratified by the legislatures of at least one-half of the states. This ratification requires only a simple majority in the state legislatures.

Special Majority (2/3rd P&V + Majority of Total) |
Special Majority (2/3rd P&V + Majority of Total) |
| State Consent |
Not Required |
Required by at least 50% of States |
Remember: States don't have the power to initiate an amendment, but they have the power to veto one that affects the federal balance if more than half of them disagree.
Key Takeaway: Amendments affecting the federal structure require a double shield: a Special Majority in both Houses of Parliament AND ratification by at least 50% of the State Legislatures.

7. The Specific Procedure under Article 368 (exam-level)
Article 368 of the Indian Constitution outlines a specific, self-contained procedure for its own amendment. Unlike ordinary legislation, a Constitutional Amendment Bill must navigate a more rigorous path to ensure that the foundational law of the land isn't changed on a whim. This process begins with the initiation of the Bill. A Bill for amendment can be introduced in either House of Parliament (Lok Sabha or Rajya Sabha) by either a Minister or a Private Member. Crucially, unlike a Money Bill or certain other financial bills, no prior permission from the President is required to introduce it Laxmikanth, M. Indian Polity, Amendment of the Constitution, p.123.
Once introduced, the Bill must be passed in each House separately by a Special Majority. This means it requires the support of more than 50% of the total membership of the House, AND at least two-thirds of the members present and voting. A critical distinction here is that there is no provision for a joint sitting in case of a deadlock between the two Houses. If one House rejects the Bill, it simply dies D. D. Basu, Introduction to the Constitution of India, The Union Legislature, p.264. This ensures that both the Lok Sabha and the Rajya Sabha have equal veto power over constitutional changes.
For amendments that seek to change the federal character of the Constitution (such as the election of the President, the distribution of legislative powers, or the representation of states in Parliament), an additional step is required: Ratification by States. The Bill must be ratified by the legislatures of at least half of the States by a simple majority. Once these hurdles are cleared, the Bill is presented to the President. Unlike ordinary Bills, the President must give his assent to a Constitutional Amendment Bill; he can neither withhold his assent nor return the Bill for reconsideration D. D. Basu, Introduction to the Constitution of India, Procedure for Amendment, p.193.
| Feature |
Ordinary Bill |

| Prior Presidential Sanction |
Required for some (e.g., Money Bills) |
Not required |
| Joint Sitting |
Allowed to resolve deadlocks |
Not permitted |
| Presidential Assent |
Can be withheld or returned |
Must be given (Mandatory) |
Key Takeaway The amendment procedure under Article 368 ensures a "rigid yet flexible" structure by requiring a Special Majority in both Houses separately and, for federal provisions, the consent of half the states, while making Presidential assent mandatory.

8. Solving the Original PYQ (exam-level)
Now that you have mastered the Amendment Procedure under Article 368, you can see how this question tests your ability to synthesize the procedural mechanics of the Union Legislature with the federal principles of the Indian Constitution. The building blocks you just learned—specifically the equal footing of the Lok Sabha and Rajya Sabha in constitutional matters and the shared sovereignty with State Legislatures—come together here to define the 'rigid' yet 'flexible' nature of our founding document.
To arrive at the correct answer, you must apply a scrutinizing lens to the specific qualifiers in each statement. Statement 1 suggests a restriction similar to that of a Money Bill; however, as explained in Laxmikanth, M. Indian Polity, an amendment bill can be initiated in either House of Parliament, emphasizing that the Rajya Sabha holds equal power in this domain. Statement 2 tests your knowledge of the Federal Character. While the Constitution protects the states' interests, it balances this by requiring ratification from not less than one-half of the states, rather than a unanimous 'all.' Because both statements fail these factual tests, the correct choice is (D) Neither 1 nor 2.
This question showcases a classic UPSC trap: the use of 'extreme' words like 'only' and 'all.' Options (A), (B), and (C) are incorrect because they accept these absolute claims which ignore the proportional safeguards built into the law. As noted in Introduction to the Constitution of India, D. D. Basu, the amendment process is designed to ensure that the federal structure cannot be altered by the Union alone, but it also avoids the 'unworkability' of requiring every single state to agree, which would make the Constitution too rigid to evolve.
