This is the 1st post in Constitutional Law-I, Unit 2 — Unit 1 traced how the Constitution came to be drafted; this post examines what kind of Constitution India actually adopted and the features that define its character.
Knowing how the Constitution was framed (Unit I) does not by itself tell you how India's system of government actually works day to day — whether power sits with one government or is shared, whether the document is easy or hard to change, or how the three organs of the State relate to each other. Before studying any individual Article, a student needs a working map of the Constitution's overall character — its "nature" — and the specific features that make it what it is, so that later provisions (federal distribution of powers, fundamental rights, judicial review) can be understood as parts of one coherent design rather than isolated rules.
1. Written and elaborate — India has a written Constitution in the formal/legal sense: a single document, deliberately drafted by the Constituent Assembly and adopted on 26 November 1949. As originally enacted it contained 395 Articles arranged in 22 Parts and 8 Schedules — already the longest written constitution of any sovereign country at the time, and it has grown further through amendments since.
2. Federal in form, but with a strong unitary bias — India has two levels of government, Union and State, each operating within its own sphere under one Constitution, which is the basic mark of a federation. However, several features (discussed below) tilt the balance firmly toward the Centre, which is why scholars describe India as "quasi-federal" rather than purely federal.
3. Parliamentary, not presidential — The Council of Ministers, headed by the Prime Minister, is drawn from and collectively responsible to the elected legislature, and the President is a constitutional (nominal) head of state — the British model, not the American separation-of-powers model.
4. Partly rigid, partly flexible — Some provisions can be amended by Parliament with a simple majority, like an ordinary law; others need a special majority, and a few — mostly the ones touching the federal structure — additionally need ratification by at least half the State legislatures. India's Constitution is therefore neither purely rigid (like the US Constitution) nor purely flexible (like the UK's unwritten constitution).
1. Dual polity — the Constitution establishes two sets of government, the Union and the States, each deriving its authority directly from the Constitution itself, not from each other.
2. Division of powers — the Seventh Schedule divides legislative subjects into the Union List, the State List, and the Concurrent List, so that each level of government knows precisely what it may legislate on.
3. Supremacy of the Constitution — neither Parliament nor a State Legislature can override the Constitution; any law inconsistent with it is void under Article 13, and this supremacy is what makes the federal division of powers meaningful.
4. Written and (partly) rigid Constitution — provisions relating to the federal structure — the distribution of legislative powers, representation of States in Parliament, and Article 368 itself — cannot be amended by Parliament alone and require ratification by at least half the State Legislatures.
5. Independent judiciary — an independent Supreme Court, empowered to decide disputes between the Union and the States (Article 131) and to strike down laws that exceed either government's constitutional authority, is essential to make any federal scheme workable.
6. Bicameral Parliament — the Rajya Sabha exists specifically to give the States a voice at the Union level, a standard feature of federations.
1. Single Constitution for the Centre and the States — unlike the United States, Indian States do not have separate constitutions of their own; one Constitution governs both levels of government.
2. Single citizenship — India has one citizenship for the whole country, not separate State citizenships as exists in some federations (examined fully in Post 4 of this Unit).
3. Parliament can alter State boundaries unilaterally — under Article 3, Parliament may form new States or alter the boundaries, names, or areas of existing States by ordinary law, and it needs only to refer the Bill to the affected State Legislature for its views, not its consent (examined fully in Post 3 of this Unit).
4. All-India Services — services like the IAS and IPS are recruited and controlled centrally but serve in the States, giving the Union administrative reach into State governance.
5. Centrally appointed Governor — the Governor of each State, the constitutional head of the State executive, is appointed by the President, not elected locally or chosen by the State.
6. Single, integrated judiciary — India has one hierarchy of courts, headed by the Supreme Court, that enforces both Union and State laws; there are no separate State court systems as exist in some federations.
7. Emergency provisions — Articles 352, 356, and 360 allow the Union, during a declared emergency, to take over the functions of a State government, shifting the federal balance decisively toward the Centre.
8. Residuary powers with the Union — under Article 248 read with Entry 97 of the Union List, any subject not mentioned in any of the three Lists falls to Parliament, not the States — the opposite of the US model, where residuary power lies with the States.
When West Bengal challenged the Union's power to acquire State-owned coal-bearing land without the State's consent, the Supreme Court, by a 5:1 majority, upheld the Union's power and held that the Indian Constitution does not embody a traditional federal system of the American kind. Sovereignty, the Court held, is not divided between the Union and the States by any agreement between equals; the States exist only because the Constitution creates them, and the Constitution itself may curtail their powers, including their proprietary rights, without needing their consent. Justice K. Subba Rao dissented, taking the view that the Union's power of acquisition should not extend to a co-equal sovereign entity's own property without its consent. This case is the clearest judicial confirmation of India's strong unitary bias, and it is why the Constitution is described as federal in form but unitary in spirit.
India adopted the British parliamentary system rather than the American presidential system. The President of India is the constitutional (nominal) head of the Union executive, while real executive power is exercised by the Council of Ministers, headed by the Prime Minister, which is drawn from the majority in the Lok Sabha and remains in office only as long as it commands that majority's confidence — this is called collective responsibility, and it is the defining feature that separates a parliamentary system from a presidential one, where the executive and legislature are elected separately and neither depends on the other's confidence to survive. The same parliamentary pattern is repeated at the State level between the Governor and the State Council of Ministers headed by the Chief Minister.
Article 368's three tiers, from easiest to hardest:
1. Simple majority — several provisions, mostly matters of administrative detail (such as creating new States or changing their names, or certain citizenship provisions), can be changed by an ordinary law of Parliament passed by simple majority — these amendments are not even treated as amendments "under Article 368."
2. Special majority — most provisions of the Constitution, including the bulk of Fundamental Rights, can only be amended by a Bill passed by a majority of the total membership of each House of Parliament, and by a majority of not less than two-thirds of the members present and voting in each House.
3. Special majority plus ratification by the States — provisions that touch the federal structure — such as the manner of electing the President, the distribution of legislative powers between Union and States, representation of States in Parliament, and Article 368 itself — additionally require ratification by the legislatures of at least one-half of the States before the President can assent to the amendment.
This three-tier design is precisely why India's Constitution is called partly rigid and partly flexible: it is flexible enough to be updated for administrative convenience without excessive difficulty, yet rigid enough that the core federal bargain cannot be altered by the Union Parliament alone.
1. Sovereign, socialist, secular, democratic republic — these defining words of the Preamble (examined fully in Post 2 of this Unit) describe the essential character of the Indian state.
2. Fundamental Rights and Directive Principles — Part III guarantees enforceable Fundamental Rights against the State, while Part IV lays down Directive Principles of State Policy that guide governance but are not directly enforceable in court — together they express both the negative limits on State power and the positive goals it must work toward (examined in Post 5 of this Unit).
3. Independent judiciary with the power of judicial review — courts can examine the constitutional validity of both legislative and executive action and strike down what exceeds constitutional limits (examined fully in Post 7 of this Unit).
4. Universal adult franchise — every citizen aged 18 or above is entitled to vote, regardless of caste, religion, sex, or literacy, a bold commitment at a time (1950) when many established democracies still restricted the franchise.
5. A single, integrated judicial system with the Supreme Court at its apex, applying uniform civil and criminal law (subject to some local variations) across the country.
6. Fundamental Duties — added later by the 42nd Amendment in 1976, Article 51-A lists duties every citizen owes to the nation, though these are not directly enforceable in court either.
Article 368 gives Parliament wide power to amend the Constitution, including Fundamental Rights, and for the Constitution's first two decades courts differed on just how far that power extended. The question was settled in the case below, and the answer given there is what ultimately protects everything discussed in this post — India's federal character, its parliamentary and republican form, the independence of its judiciary — from being erased by a simple constitutional amendment.
In the largest bench ever assembled by the Supreme Court (13 judges), the Court held by a narrow majority that Parliament's power to amend the Constitution under Article 368 is wide, but not unlimited — Parliament cannot use its amending power to destroy or alter the "basic structure" or fundamental framework of the Constitution, even though it can amend virtually any individual provision, including Fundamental Rights. While the Court did not lay down a closed list, the elements identified as part of the basic structure across this and later cases include the supremacy of the Constitution, the republican and democratic form of government, the secular character of the Constitution, separation of powers between the legislature, executive, and judiciary, the federal character of the Constitution, and the power of judicial review. This is why the "nature" of India's Constitution discussed throughout this post is treated as permanent — Parliament may amend the text, but not the Constitution's essential identity.
Unit I, Post 2 introduced the general theory of how constitutions are classified worldwide — written versus unwritten, and rigid versus flexible. This post has applied that theory specifically to India: a written Constitution that is partly rigid and partly flexible, and a federal structure with a pronounced unitary tilt. That earlier post remains the place to revisit the general classification theory; this post focuses only on where India actually sits within it.
| Aspect | Federal Feature | Unitary Feature |
|---|---|---|
| Government structure | Two levels — Union and States, each with defined powers | Single Constitution governs both levels; States have no separate constitutions |
| Citizenship | — | Single citizenship for the whole country |
| Legislative power | Union, State, and Concurrent Lists (Seventh Schedule) | Residuary powers rest with the Union, not the States |
| State boundaries | — | Parliament can alter them unilaterally under Article 3 |
| Executive | Independent State governments headed by an elected Chief Minister | Governor, the State's constitutional head, is centrally appointed |
| Judiciary | Independent judiciary resolves Union-State disputes | Single, integrated court system, not separate State judiciaries |
| Emergency | — | Union can override State autonomy under Articles 352, 356, and 360 |
Suppose Parliament passes a law reorganizing two neighbouring States, merging part of one into the other, after only asking the affected State Legislatures for their views (not their consent) under Article 3. The State governments strongly object, but Parliament proceeds anyway. Could the States successfully challenge this in court purely because they were not consulted? No — because Article 3 does not require the consent of the affected States, only that the Bill be referred to them for their views within a period fixed by the President; failing to secure agreement is not itself unconstitutional. This is precisely the kind of unitary feature — the Centre able to redraw the federal map without State consent — that distinguishes India from a strict, agreement-based federation like the United States, and it is exactly what the Supreme Court confirmed more broadly in State of West Bengal v. Union of India.
