Centre-State Relations in India: A UPSC Guide

By Dooit UPSC expert · 16 August 2026 · 12 min read

Indian federalism is a bargain: the states are strong enough to govern their people, and the Centre is strong enough to hold the Union together. Centre-State relations are simply the rules of that bargain — and few Polity topics reward a clear mental map as richly as this one does in both Prelims and Mains.

In three decades of guiding aspirants, I have seen this topic scare more candidates than almost any other in Polity — not because it is hard, but because it is scattered. The Articles run across two Parts of the Constitution, the Seventh Schedule hides three long lists, and the words "cooperative federalism" get thrown around without anchoring. So let us do the opposite of scatter. We will build the topic in three clean blocks — legislative, administrative, financial — and hang every fact on a specific Article. Learn it this way once and it stays with you for the interview.

First, why "quasi-federal"?

The Constitution nowhere uses the word "federation". Article 1 calls India a "Union of States", and Dr B. R. Ambedkar explained the choice deliberately: the Union is indestructible, and the states have no right to secede. What we have is a federal structure with a strong unitary bias — a system the Supreme Court and scholars often describe as quasi-federal. The federal features are real: two levels of government, a written and supreme Constitution, a division of powers, an independent judiciary, and bicameralism. But the unitary tilt is just as real: a single citizenship, a single integrated judiciary, All-India Services that serve both levels, the Centre's power to redraw state boundaries under Article 3, and emergency provisions that can turn the federation temporarily unitary.

Hold that tension in your head as the theme of the whole topic. Every provision that follows is either the federal principle at work or the unitary corrective. When a Mains question asks you to "examine" Centre-State relations, this balance is your thesis.

Block 1 — Legislative relations (Articles 245–255)

These Articles answer two questions: who can make law on what, and what happens when their laws collide.

Territorial and subject-matter division

Article 245 sets the territorial extent — Parliament makes law for the whole or any part of India, a state legislature for the whole or any part of that state. Article 246 then divides the subject matter through the Seventh Schedule's three lists. This division is the spine of the entire topic, so commit the logic, not just the numbers:

Originally the Union List had 97 subjects, the State List 66 and the Concurrent List 47; subsequent amendments have altered these counts (for instance, the 42nd Amendment shifted education, forests, and weights and measures to the Concurrent List). Do not memorise the exact present tally — examiners rarely test it, and it is disputed even in reference books. Instead, remember the hierarchy of predominance: in a conflict, the Union List prevails over the Concurrent, and the Concurrent prevails over the State List.

When the Centre may enter the State List

The division is not watertight. In five clearly defined situations, Parliament can legislate on State List subjects — and these exceptions are prime Prelims material:

• Article 249 — when the Rajya Sabha passes a resolution by a two-thirds majority that a State List subject has become a matter of national interest.
• Article 250 — automatically, during a National Emergency.
• Article 252 — when two or more states pass resolutions requesting Parliament to legislate for them (as with the laws on organ transplantation).
• Article 253 — to implement international treaties, agreements or conventions.
• Article 356 — when President's Rule is in force in a state and Parliament exercises the state legislature's power.

Doctrine of repugnancy — Article 254

On a Concurrent subject, if a state law conflicts with a central law, the central law prevails and the state law is void to the extent of the repugnancy. There is one important escape: if the state law was reserved for the President and received assent, it prevails in that state — though Parliament can still override it later. Pair this Article with the idea of predominance above and legislative relations become almost intuitive.

Block 2 — Administrative relations (Articles 256–263)

Making law is one thing; enforcing it is another. Administrative relations govern how the executive powers of the Centre and states coexist without collision.

The default rule (Articles 256 and 257) is that a state must exercise its executive power so as to comply with central laws, and must not impede the executive power of the Union. The Centre may give a state such directions as it considers necessary for that purpose. If a state fails to comply with a lawful central direction, Article 365 kicks in — the President may hold that a situation has arisen in which the state's government cannot be carried on in accordance with the Constitution, which is a gateway to Article 356.

Instruments of cooperation and control

• All-India Services (Article 312) — the IAS, IPS and Indian Forest Service are recruited and trained by the Centre but serve the states, giving the Union a permanent administrative presence in every state.
• Article 262 — Parliament may provide for adjudication of inter-state river water disputes and can bar even the Supreme Court from such disputes (the basis of the Inter-State River Water Disputes Act).
• Article 263 — the President may establish an Inter-State Council to inquire into and advise on disputes and coordination between states, and between the Centre and states. It was finally set up in 1990 on the Sarkaria Commission's recommendation.
• Full faith and credit (Article 261) — public acts, records and judicial proceedings of the Union and every state are given full recognition throughout India.

Notice how these instruments lean unitary. The All-India Services and the Centre's power of direction are exactly the "strong Centre" features that make Indian federalism quasi-federal in practice, not just on paper.

Block 3 — Financial relations (Articles 268–293)

Money is where federalism is truly tested. A state with grand legislative powers but empty coffers is not autonomous. Part XII therefore sets out how taxes are levied, collected and shared — and this block connects to several topics you may already have studied.

Division of taxing powers and the GST turning point

Taxing powers, like legislative powers, are distributed through the Seventh Schedule — the Centre taxes income (barring agricultural income), customs and corporation tax, while states tax land, agricultural income and (historically) sales. The single biggest change to this arrangement came with the 101st Constitutional Amendment Act, 2016, which introduced the Goods and Services Tax and created the GST Council under Article 279A as a joint Centre-State body. If you have read our note on the GST Council and Article 279A, place it here — it is the clearest live example of cooperative federalism in the financial sphere.

The Finance Commission — the balancing wheel

Because the Centre collects the most buoyant taxes while states carry heavy spending responsibilities, there is a built-in vertical imbalance. Article 280 provides the corrective: a Finance Commission, constituted by the President every fifth year, that recommends how the net proceeds of central taxes should be shared between the Centre and states (vertical devolution) and among the states (horizontal devolution), along with grants-in-aid under Article 275. Read this alongside our detailed piece on the Finance Commission and Article 280 to see how the numbers actually flow.

Article 293 adds a crucial string: a state cannot raise a fresh loan without the Centre's consent if it is already indebted to the Union — another quiet unitary lever inside the financial architecture.

The tension points examiners love

Mains questions rarely ask you to list Articles. They probe the friction. Keep these live flashpoints ready, each tied to a constitutional hook:

• The Governor — appointed by the Centre, holding discretionary powers, and often at the centre of Centre-State friction over assent to bills and recommendations for President's Rule. Our piece on the Governor's powers and role unpacks this in depth.
• Article 356 (President's Rule) — historically misused to dismiss opposition state governments until the Supreme Court's S. R. Bommai (1994) judgment made it judicially reviewable and insisted that the majority be tested on the floor of the House.
• Fiscal autonomy after GST — states surrendered independent taxation for a share in a common pool, raising debates about compensation and the erosion of their revenue independence.
• Deployment of central forces and agencies — recurring disputes over the Centre acting within a state's law-and-order domain, a State List subject.

The commissions you must be able to name

Two official commissions dominate the answer-writing on this topic, and knowing their names and thrust instantly lifts an answer:

You do not need every recommendation. Remember the common thread: both commissions accepted a strong Centre as necessary for unity but pushed for restraint, consultation and institutional forums like the Inter-State Council. That single sentence, deployed well, signals a mature grasp of the debate.

How to revise this topic so it sticks

Here is the method I have given aspirants for years, and it works because it mirrors how the Constitution itself is organised:

1. Fix the three blocks first — legislative (245–255), administrative (256–263), financial (268–293). If you can recall which Part and range each belongs to, half the battle is won.
2. Attach the "star" Articles to each block — 246 and the lists, 249–253, 254 for legislative; 262 and 263 for administrative; 280 and 279A for financial.
3. Overlay the theme — for every provision, ask: is this the federal principle or the unitary corrective? This turns dry Articles into an argument you can write.
4. Link to current affairs — every Governor row, GST Council meeting or central-agency dispute is a live example. File each news item under the Article it illustrates.

Do this and Centre-State relations stops being a swamp of numbers and becomes a story you can tell — which is exactly what a good Mains answer, and a confident interview, require.
