1. Distribution of Legislative Subjects: The Three Lists (basic)
To understand how India functions as a democracy, we must first look at the
Seventh Schedule of the Constitution. Since India follows a federal structure, power is not concentrated in one place; instead, it is divided between the Centre (Union) and the States. This division is clearly demarcated through three functional lists under
Article 246, ensuring that both levels of government know exactly which areas they are responsible for. This clarity prevents legal chaos and allows the Parliament and State Legislatures to operate within their own 'sovereign' spheres
Introduction to the Constitution of India, DISTRIBUTION OF LEGISLATIVE AND EXECUTIVE POWERS, p.376.
The distribution is categorized into three distinct lists based on the nature of the subject matter:
| List |
Authority |
Scope & Examples |
| Union List (List I) |
Parliament (Exclusive) |
Subjects of national importance like Defense, Foreign Affairs, and Banking. Currently has 98 subjects Indian Polity, Federal System, p.139. |
| State List (List II) |
State Legislatures (Exclusive) |
Subjects of local or regional importance like Police, Public Health, and Agriculture. Currently has 59 subjects Indian Polity, Federal System, p.139. |
| Concurrent List (List III) |
Both Centre & States |
Subjects where varying local needs exist but national uniformity is desirable, such as Education, Forests, and Marriage. Currently has 52 subjects Indian Polity, Federal System, p.139. |
A vital principle to remember is the Rule of Supremacy. While both the Centre and States can legislate on the Concurrent List, if there is a conflict between a Central law and a State law on the same subject, the Central law usually prevails. Furthermore, any subject not mentioned in any of the three lists—known as Residuary Powers—is handled exclusively by the Parliament under Article 248. This ensures that as society evolves (e.g., Cyber Law), the Union has the authority to step in Indian Polity, Centre State Relations, p.164.
Finally, there is a fascinating exception under Article 253. To maintain India's credibility on the global stage, the Parliament has the overriding power to make laws on any subject—even those in the State List—if it is necessary to implement an international treaty, agreement, or convention. In such cases, the Union does not need the consent of the States. This ensures that federalism does not become a hurdle in fulfilling our external sovereign obligations.
Remember 1-2-3: List 1 (Union) is National, List 2 (State) is Local, List 3 (Concurrent) is Shared. If it’s not on the list, the Union takes the rest!
Key Takeaway The Seventh Schedule divides legislative powers into three lists to ensure administrative clarity, with the Parliament holding exclusive rights over national matters and residuary subjects to maintain a strong federal balance.

2. Territorial Extent of Central and State Legislation (basic)
When we talk about the power to make laws, the first thing we must define is where those laws apply. In a federal system like India, the Constitution clearly demarcates the geographical boundaries of legislative authority under Article 245. Think of it as the "legal map" within which the Union and the States must operate to ensure they don't step on each other's toes.
The Parliament has the most expansive reach. It can make laws for the whole or any part of the territory of India, which includes not just the States, but also Union Territories and any other area currently included in India's map D. D. Basu, Introduction to the Constitution of India, DISTRIBUTION OF LEGISLATIVE AND EXECUTIVE POWERS, p.376. Crucially, the Parliament also possesses the power of "extra-territorial legislation." This means a law passed by the Parliament can apply to Indian citizens and their property anywhere in the world — a power that no State Legislature enjoys M. Laxmikanth, Indian Polity, Important Doctrines of Constitutional Interpretation, p.652.
On the other hand, the State Legislatures have a much more localized jurisdiction. A State can only make laws for the whole or any part of that specific State. Generally, a law made by a State is not applicable outside its boundaries unless there is a "territorial nexus" — meaning the object or person the law is targeting has a clear connection to that State M. Laxmikanth, Indian Polity, Important Doctrines of Constitutional Interpretation, p.652.
| Feature |
Parliament (Union) |
State Legislature |
| Geographic Scope |
Entire territory of India (States + UTs) |
Only the territory of that specific State |
| Extra-territorial Reach |
Yes (applies to citizens/property abroad) |
No |
| Subject Overlap |
Can legislate on State subjects for UTs or for International Treaties |
Confined strictly to State/Concurrent lists within its borders |
However, this power is not absolute. For instance, the Parliament can override the State List under Article 253 to implement international treaties, ensuring that India speaks with one voice on the global stage without needing the consent of individual states. Conversely, the President or Governors have the power to restrict or modify the application of Parliamentary Acts in certain areas like the Andaman and Nicobar Islands or Scheduled Areas to protect local interests M. Laxmikanth, Indian Polity, Union Territories, p.411.
Remember Parliament is "Global" (citizens abroad), but the State is "Local" (borders only).
Key Takeaway While the Parliament can legislate for the entire nation and even Indian interests abroad, State Legislatures are strictly confined to their own geographical boundaries unless a clear territorial nexus exists.

3. Residuary Powers of Legislation (intermediate)
In a federal setup, the Constitution divides subjects of legislation into different lists to ensure clarity between the Centre and the States. However, the world is dynamic—new subjects like Cyber Law or Space Research emerge that weren't envisioned by the Constitution-makers. This is where Residuary Powers come into play. These are the "catch-all" powers intended to cover any matter not specifically listed in the Union, State, or Concurrent Lists of the Seventh Schedule.
Under Article 248, the Indian Parliament has the exclusive power to make laws with respect to any matter not enumerated in the three lists. This unique authority also includes the power to levy residuary taxes, ensuring that the Union has the fiscal flexibility to meet modern challenges M. Laxmikanth, Indian Polity, Chapter: Centre-State Relations, p.146. It is important to note that if a dispute arises over whether a subject is truly "residuary," the final authority to decide lies with the Judiciary D.D. Basu, Introduction to the Constitution of India, Chapter: Distribution of Legislative and Executive Powers, p.378.
Our choice to vest these powers in the Centre rather than the States reflects the "Unitary bias" of our federation. While countries like the USA and Australia vest residuary powers in the states to ensure greater decentralization, India chose the Canadian model to maintain a strong central authority. This was a significant shift from the Government of India Act of 1935, which had a very different arrangement:
| System/Act |
Vesting of Residuary Powers |
| USA & Australia |
States / Provinces |
| Canada & India |
Centre / Parliament |
| Govt. of India Act, 1935 |
Governor-General (at his discretion) |
Beyond the general residuary power under Article 248, the Parliament also possesses overriding authority under Article 253. This allows the Centre to legislate on even State List subjects if it is necessary to implement international treaties or conventions. This ensures that India’s federal structure does not prevent the nation from fulfilling its global sovereign obligations, even without the consent of the states.
Remember C-C-C: Canadian model, Centralized power, Catch-all bucket (Article 248).
Key Takeaway Residuary power is the Parliament's exclusive authority to legislate on any subject not found in the Seventh Schedule, following the Canadian precedent of a strong Centre.

4. Administrative Relations: Union Control over States (intermediate)
In a federal setup, the Union and States usually operate in their own spheres. However, the Indian Constitution ensures that the Union executive power is superior to that of the States to maintain national integrity. This administrative control starts with Article 256, which mandates that States must exercise their executive power to ensure compliance with laws made by Parliament. If a State fails to comply with these directions, the Centre can even invoke Article 365 to take over the state administration, citing a breakdown of constitutional machinery Indian Polity, Centre-State Relations, p.165.
One of the most potent tools of Union control is Article 253. This provision grants Parliament the exclusive power to make any law for the whole or any part of India for implementing international treaties, agreements, or conventions. What makes this extraordinary is the 'notwithstanding' clause: Parliament can legislate even on subjects mentioned in the State List if it is necessary to fulfill an international obligation. Unlike other mechanisms that might require state consent, Article 253 allows the Union to act unilaterally to ensure India’s credibility on the global stage Indian Polity, Centre-State Relations, p.148.
Furthermore, under Article 257, the Union can give directions to a State regarding the construction and maintenance of means of communication declared to be of national or military importance, and for the protection of railways within the state. This relationship isn't just about 'command'; it also involves 'cooperation.' For instance, Article 258 allows the Union to entrust its executive functions to a State government with its consent (or via a law passed by Parliament), effectively using the State machinery as an agent of the Union Indian Polity, Centre-State Relations, p.165.
As the Sarkaria Commission noted, this supremacy is not meant to undermine states but to act as a technique to avoid 'absurdity' and resolve conflicts, ensuring that the diverse parts of the country move in harmony with national policy Indian Polity, Centre-State Relations, p.148.
Key Takeaway The Union holds ultimate administrative leverage over States through mandatory directives and the unique power to override State jurisdiction to fulfill international obligations (Article 253).

5. Parliamentary Legislation in the State Field (Articles 249, 250, 252) (exam-level)
In a normal federal setup, the Parliament and State Legislatures operate within their own exclusive spheres. However, the Indian Constitution provides for five extraordinary situations where this 'federal wall' becomes porous, allowing the Parliament to legislate on subjects specifically reserved for the states. This reflects the
unitary tilt of our Constitution, ensuring that the national interest prevails over regional autonomy when circumstances demand it.
The first major gateway is
Article 249. If the
Rajya Sabha (the 'Council of States') passes a resolution supported by
two-thirds of members present and voting, it can authorize Parliament to make laws on a State List subject in the national interest
Indian Polity, M. Laxmikanth, Parliament, p.260. Such a resolution remains in force for one year but can be renewed indefinitely. Similarly, under
Article 250, if a
Proclamation of Emergency is in operation, the Parliament gains the power to legislate on any matter in the State List for the whole or any part of India
Introduction to the Constitution of India, D. D. Basu, EMERGENCY PROVISIONS, p.413. These laws cease to have effect six months after the emergency has ended.
Another unique mechanism is found in
Article 252, where
two or more states can pass resolutions requesting the Parliament to enact a law on a State List subject for them. Crucially, once such a law is passed, the power of those state legislatures to amend or repeal that law is terminated; only Parliament can modify it
Indian Polity, M. Laxmikanth, World Constitutions, p.703. Finally,
Article 253 provides the Parliament with overriding power to legislate on State List subjects to implement
international treaties or agreements. This ensures that the Union government can fulfill its global obligations without being hindered by the constitutional division of powers. Unlike Article 252, this does not require the consent of any state.
| Article | Trigger Condition | Key Requirement |
|---|
| 249 | National Interest | Rajya Sabha resolution (Special Majority) |
| 250 | National Emergency | Proclamation under Art. 352 |
| 252 | Consent of States | Resolution by 2 or more State Legislatures |
| 253 | International Obligations | Treaty/Convention implementation |
Key Takeaway The Parliament can 'override' the State List under specific conditions (National Interest, Emergency, State Consent, or International Treaties) to maintain the integrity and functionality of the Indian Union.

6. Legislation for International Agreements (Article 253) (exam-level)
In a federal setup like India, there is a clear division of powers between the Union and the States. However, imagine a scenario where India signs a global treaty on biodiversity, but 'Forests' or 'Agriculture' are subjects where states usually have a say. If the Center couldn't implement these treaties because of state opposition, India's global credibility would suffer. To prevent this, **Article 253** acts as a unique 'sovereign bridge.' It empowers the Parliament to make laws on **any subject**, including those in the **State List**, if it is necessary to implement an international treaty, agreement, or convention
Indian Polity, Centre-State Relations, p.147.
The defining feature of Article 253 is that it operates **independently of state consent**. While other provisions (like Article 252) require states to pass resolutions or give permission for the Parliament to step into their territory, Article 253 grants the Union an overriding authority. This ensures that the federal structure does not become an obstacle to India performing its external sovereign functions
Introduction to the Constitution of India, DISTRIBUTION OF LEGISLATIVE AND EXECUTIVE POWERS, p.379. This constitutional design is supported by **Article 51 (DPSP)**, which encourages the State to foster respect for international law
Introduction to the Constitution of India, THE PHILOSOPHY OF THE CONSTITUTION, p.24.
Historically, several landmark legislations have been enacted using this power. For instance, laws regarding the environment (like the Air and Water Pollution Acts) or the **Geneva Convention Act, 1960**, were passed by Parliament even though they touched upon subjects that normally fall under state jurisdiction
Introduction to the Constitution of India, DISTRIBUTION OF LEGISLATIVE AND EXECUTIVE POWERS, p.379.
| Feature | Article 252 | Article 253 |
|---|
| Purpose | Legislation for two or more states by consent. | Implementation of international agreements. |
| State Consent | Mandatory (States must request the law). | Not Required (Union has unilateral power). |
| Subject Matter | State List subjects specifically requested. | Any subject (even List II) needed for the treaty. |

7. Solving the Original PYQ (exam-level)
Now that you have mastered the Division of Powers and the Seventh Schedule, this question tests your understanding of the exceptions to the general rule of federalism. While the Constitution usually respects state autonomy in matters within the State List, Article 253 serves as a crucial bridge between domestic law and international diplomacy. It ensures that the Union government's commitment on the global stage is not hindered by internal federal boundaries, effectively centralizing legislative power for the specific purpose of treaty implementation. This connects the building blocks of Legislative Relations to the practical reality of External Sovereignty.
To arrive at the correct answer, (D) Without the consent of any State, you must apply the logic of the 'notwithstanding' clause found in Article 253. The reasoning is straightforward: if the Parliament were dependent on state approval to fulfill international obligations, India's global credibility would be compromised by internal political disagreements. Therefore, the Constitution grants Parliament exclusive and overriding power to make laws on any subject—even those in the State List—to implement treaties. When you see "international treaties" in a UPSC question, your mind should immediately trigger the Unitary tilt of the Indian Constitution, which bypasses the usual federal requirements.
UPSC frequently uses options (A), (B), and (C) as distractors by borrowing language from other parts of the Constitution. For instance, the "consent of the majority of States" is a requirement for certain Constitutional Amendments under Article 368, while the "consent of the States" reflects the procedure under Article 252 (where two or more states request Parliament to legislate on a state subject). These are common traps designed to test if you can distinguish between different types of extraordinary legislative powers. In the specific context of Article 253, the authority is unilateral, making the consent of any state entirely unnecessary.
