The Constitutional Framework
The Constitution of India establishes a federal structure — though one with a strong unitary bias — by dividing legislative power between Parliament and the State Legislatures.
This division is not left to inference or convention, as in some federal systems. It is spelled out with precision in Article 246 of the Constitution, read with the Seventh Schedule, which contains three lists enumerating the subjects on which each legislature may enact law.
The three lists are:
- List I — Union List (Parliament alone legislates)
- List II — State List (State Legislature alone legislates)
- List III — Concurrent List (Both Parliament and State Legislatures may legislate)
This tripartite division is the architectural blueprint of Indian federalism. Every law enacted in India — central or state — must find its source of competence in one of these three lists. A law that cannot be traced to any entry in any list, or that is enacted by a legislature lacking competence over that entry, is unconstitutional and void.
List I — The Union List
Nature and Scope
The Union List contains 97 entries and covers subjects of national importance, subjects requiring uniformity across the country, and subjects involving India’s relations with the external world.
Parliament has exclusive legislative competence over every entry in the Union List. No State Legislature can legislate on a Union List subject, period. If a State Legislature purports to enact a law that, in its pith and substance, falls within a Union List entry, that law is unconstitutional regardless of how it is dressed up or titled.
Why These Subjects Are Reserved for Parliament
The framers of the Constitution reserved certain subjects for exclusive Parliamentary legislation because:
Uniformity is essential — Defence, currency, foreign affairs, atomic energy, and railways cannot have fifty different state regimes. A country with twenty-eight states cannot have twenty-eight armies, twenty-eight currencies, or twenty-eight foreign policies.
National security demands central control — Entry 1 (Defence), Entry 2 (Naval, Military and Air Forces), Entry 9 (Preventive Detention in connection with defence), and Entry 41 (Trade and Commerce with foreign countries) are all Union subjects because any fragmentation of authority in these areas would undermine the integrity and security of the state.
Economic coherence requires central regulation — Banking, insurance, stock exchanges, inter-state trade, income tax, customs, and corporation tax are Union subjects because a fragmented regulatory regime would destroy the single national market.
Key Entries in the Union List
Entry 1 — Defence of India; armed forces of the Union.
Entry 2 — Naval, military and air forces; any other armed forces of the Union.
Entry 14 — Foreign affairs; all matters which bring the Union into relation with any foreign country.
Entry 20 — Citizenship, naturalisation and aliens.
Entry 41 — Trade and commerce with foreign countries; import and export across customs frontiers.
Entry 43 — Banking other than co-operative societies.
Entry 44 — Incorporation, regulation and winding up of corporations whether trading or not, with objects not confined to one state — this is why the Companies Act is central legislation.
Entry 54 — Regulation of mines and mineral development to the extent to which such regulation and development under the control of the Union is declared by Parliament by law to be expedient in the public interest.
Entry 66 — Co-ordination and determination of standards in institutions for higher education or research and scientific and technical institutions.
Entry 82 — Taxes on income other than agricultural income — the basis of the Income Tax Act.
Entry 83 — Duties of customs including export duties.
Entry 84 — Duties of excise on tobacco and other goods manufactured or produced in India except alcoholic liquors for human consumption, opium, narcotics.
Entry 97 — The residuary entry. Any matter not enumerated in List II or List III falls within Parliament’s exclusive competence. This is a critical provision — the residuary power in India vests with the Union, not the States, unlike in the United States where residuary power vests with the states.
List II — The State List
Nature and Scope
The State List contains 66 entries and covers subjects of local or regional importance — matters where diversity of approach across states is not merely tolerable but desirable. State Legislatures have exclusive legislative competence over State List subjects, subject to three important exceptions discussed below.
Why These Subjects Are Left to the States
Local conditions vary enormously — Agriculture, land rights, water, irrigation, markets and fairs, local governance, and public order are state subjects because conditions in Punjab differ radically from those in Kerala, and a uniform national law would be either too rigid for some states or too permissive for others.
Cultural and social diversity — Subjects like burial grounds, pilgrimage within the state, libraries, and theatres are state subjects because they reflect the diversity of India’s social and cultural fabric.
Revenue sources for states — Certain taxes are exclusively assigned to states to give them financial autonomy: land revenue, taxes on agricultural income, taxes on the sale of land, excise on alcohol, taxes on vehicles, taxes on professions and callings, taxes on entertainment, and taxes on markets.
Key Entries in the State List
Entry 1 — Public order (but not including use of naval, military or air forces in aid of civil power).
Entry 2 — Police (including railway and village police).
Entry 5 — Local government — municipal corporations, improvement trusts, district boards, etc.
Entry 6 — Public health and sanitation; hospitals and dispensaries.
Entry 14 — Agriculture including agricultural education and research, protection against pests and prevention of plant diseases.
Entry 17 — Water, that is to say, water supplies, irrigation and canals, drainage and embankments, water storage and water power subject to the provisions of Entry 56 of List I.
Entry 18 — Land, that is to say, rights in or over land, land tenures including the relation of landlord and tenant, and the collection of rents; transfer and alienation of agricultural land; land improvement and agricultural loans; colonisation. This is the foundation of all state tenancy and land reform legislation.
Entry 21 — Fisheries.
Entry 22 — Courts of wards; encumbered and attached estates.
Entry 26 — Trade and commerce within the State subject to the provisions of Entry 33 of List III.
Entry 45 — Land revenue, including the assessment and collection of revenue, the maintenance of land records, survey for revenue purposes and records of rights.
Entry 51 — Excise on alcoholic liquors for human consumption, opium, Indian hemp and other narcotic drugs and narcotics, but not including medicinal and toilet preparations containing alcohol. This is why states have independent excise policies and why the liquor question became a state matter in India.
Entry 62 — Taxes on luxuries including taxes on entertainments, amusements, betting and gambling.
Entry 63 — Taxes on professions, trades, callings and employments.
Entry 65 — Jurisdiction and powers of all courts, except the Supreme Court, with respect to State List matters.
The Three Exceptions to State List Exclusivity
The State List is not absolutely exclusive. Parliament may legislate on State List subjects in three exceptional circumstances:
Article 249 — National Interest: If the Rajya Sabha passes a resolution supported by two-thirds of members present and voting declaring that it is necessary in the national interest for Parliament to legislate on a State List subject, Parliament may do so for a period of one year, renewable.
Article 250 — National Emergency: During a Proclamation of Emergency under Article 352, Parliament acquires the power to legislate on any State List subject for the duration of the Emergency and a period of six months thereafter.
Article 356 — President’s Rule: When President’s Rule is imposed in a state under Article 356, Parliament may exercise the legislative functions of the State Legislature, including on State List subjects.
These exceptions reveal the unitary bias in the Indian federal structure — the Centre can override the States’ exclusive legislative domain in extraordinary circumstances, something that would be constitutionally impermissible in a purely federal system like the United States.
List III — The Concurrent List
Nature and Scope
The Concurrent List contains 52 entries and covers subjects where both Parliament and State Legislatures are competent to legislate. The Concurrent List exists because the framers recognised that certain subjects are important enough to require national standards but flexible enough to permit state variation within those standards.
The Resolution of Conflict — Article 254
When both Parliament and a State Legislature have enacted laws on the same concurrent subject, and those laws conflict, Article 254(1) resolves the conflict in Parliament’s favour — the central law prevails and the state law is void to the extent of repugnancy. This is where the Doctrine of Occupied Field, discussed in our earlier commentary, becomes operative.
The single exception is Article 254(2) — if the state law has received Presidential assent, it prevails over the central law in that state, unless Parliament subsequently re-occupies the field.
Key Entries in the Concurrent List
Entry 1 — Criminal law, including all matters included in the Indian Penal Code at the commencement of this Constitution. This is why states can enact their own criminal laws — subject to Parliamentary supremacy.
Entry 2 — Criminal procedure, including all matters included in the Code of Criminal Procedure at the commencement of this Constitution.
Entry 5 — Marriage and divorce; infants and minors; adoption; wills, intestacy and succession; joint family and partition; all matters in respect of which parties in judicial proceedings were immediately before the commencement of this Constitution subject to their personal law. The entire body of personal law — Hindu, Muslim, Christian, Parsi — derives its concurrent legislative foundation from this entry.
Entry 6 — Transfer of property other than agricultural land; registration of deeds and documents. The Transfer of Property Act and the Registration Act are both concurrent subjects — hence the extensive state-level variations in stamp duty, registration fees, and procedural rules.
Entry 7 — Contracts, including partnership, agency, contracts of carriage, and other special forms of contracts, but not including contracts relating to agricultural land. The Indian Contract Act, the Sale of Goods Act, and the Partnership Act all derive from this entry.
Entry 11A — Administration of justice; constitution and organisation of all courts, except the Supreme Court and the High Courts. Inserted by the 42nd Amendment.
Entry 12 — Evidence and oaths; recognition of laws, public acts and records, and judicial proceedings.
Entry 13 — Civil procedure, including all matters included in the Code of Civil Procedure at the commencement of this Constitution, limitation and arbitration.
Entry 17 — Prevention of cruelty to animals.
Entry 20 — Economic and social planning. This single entry is the constitutional basis for India’s entire planning apparatus — five-year plans, NITI Aayog, and national development schemes.
Entry 23 — Social security and social insurance; employment and unemployment.
Entry 24 — Welfare of labour including conditions of work, provident funds, employers’ liability, workmen’s compensation, invalidity and old age pensions and maternity benefits. The entire body of Indian labour law — Factories Act, Minimum Wages Act, Payment of Wages Act — derives from this entry.
Entry 25 — Education, including technical education, medical education and universities, subject to the provisions of entries 63, 64, 65 and 66 of List I; vocational and technical training of labour. Added by the 42nd Amendment — previously education was a state subject.
Entry 26 — Legal, medical and other professions. The Advocates Act and the Medical Council Act derive from this entry.
Entry 29 — Prevention of extension from one State to another of infectious or contagious diseases or pests affecting men, animals or plants.
Entry 33 — Trade and commerce in, and the production, supply and distribution of certain essential commodities. The Essential Commodities Act derives from this entry.
Entry 40 — Archaeological sites and remains other than those declared by or under law made by Parliament to be of national importance.
Entry 45 — Inquiries and statistics for the purposes of any of the matters specified in List II or List III.

The Doctrine of Pith and Substance: The Unavoidable Companion
No discussion of the three lists is complete without understanding the Doctrine of Pith and Substance, which courts apply when a law enacted by one legislature appears to encroach on the domain of another. The doctrine holds that when examining legislative competence, courts look to the true nature and character of the law — its dominant purpose and its primary effect — rather than its incidental or peripheral operation on a subject outside the enacting legislature’s competence.
A state law on public health that incidentally affects the manufacture of drugs is, in its pith and substance, a public health law (State List Entry 6), not a drugs law (Concurrent List Entry 19), and is valid. A central law on banking that incidentally affects land transactions is a banking law (Union List Entry 43), not a land law (State List Entry 18), and is valid.
Courts apply this doctrine with considerable sophistication, recognising that in a complex regulatory environment, perfect compartmentalisation is impossible and some degree of overlap is inevitable.
The Federal Balance: Where Does Power Actually Lie?
A candid constitutional assessment reveals that Indian federalism is structurally tilted toward the Centre:
The residuary power vests with Parliament — unlike the United States where it vests with the states. Any new subject not in any list goes to Parliament, not the states.
The Concurrent List itself favours the Centre — when conflict arises, central law wins under Article 254, and the Doctrine of Occupied Field can preclude state legislation even in the absence of direct conflict.
The exceptions to State List exclusivity — Articles 249, 250, and 356 — give the Centre the ability to invade state legislative territory in extraordinary circumstances, a power the states have no reciprocal right to exercise.
The Union List’s breadth — particularly Entry 97, the residuary entry, and broad entries on economic regulation — gives Parliament enormous legislative reach.
Dr. B.R. Ambedkar, in the Constituent Assembly debates, described India as a federation that could function as a unitary state in times of need. The three-list structure, with its built-in central dominance, is the constitutional expression of that design philosophy.
Conclusion
The Union List, State List, and Concurrent List are not merely taxonomic conveniences. They are the constitutional allocation of sovereign legislative power between two levels of government in a country of extraordinary diversity and complexity. For the practising lawyer, understanding which list governs a subject is the first and most fundamental question in any challenge to legislative validity, any conflict between central and state law, and any advice on regulatory compliance across state boundaries.
Every constitutional challenge begins here. Every statutory interpretation question is informed by this. And every federal dispute — whether between the Centre and a state or between competing regulatory regimes — finds its resolution by returning, always, to the Seventh Schedule and its three lists.
