Freedom of Trade, Commerce and Intercourse

Freedom of trade, commerce and intercourse throughout the territory of India is guaranteed by Article 301, which opens Part XIII of the Constitution. It declares that economic activity and movement of goods and people shall not be obstructed by internal barriers between one State and another, or within a State, subject to the other provisions of the same Part. The idea is to keep India a single economic unit rather than a collection of fragmented markets.

What Article 301 Guarantees

Article 301 states: "Subject to the other provisions of this Part, trade, commerce and intercourse throughout the territory of India shall be free." The freedom is not confined to inter-State movement alone; it extends to intra-State trade as well, so that a State cannot erect barriers even within its own borders that choke the free flow of goods, services and people. The underlying object is to dismantle the kind of customs-barrier mentality that existed among princely states and provinces before independence, and to treat India's territory as one continuous economic space.

This freedom is not absolute. It operates "subject to the other provisions of this Part" — meaning Articles 302 to 305 carve out the permissible restrictions, and Article 301 must always be read along with them.

Restrictions Parliament May Impose — Article 302

Article 302 empowers Parliament to impose, by law, restrictions on the freedom of trade, commerce or intercourse between one State and another, or within any part of India, when required in the public interest. This gives the Union the authority to regulate trade for larger policy reasons — for instance, to manage supply of essential goods — while still operating within the constitutional scheme of Part XIII.

Non-Discrimination — Article 303

Article 303(1) bars both Parliament and State legislatures from making any law that gives preference to one State over another, or discriminates between States, merely by virtue of an entry relating to trade and commerce in the Seventh Schedule Lists. This non-discrimination principle applies even to Parliament's own Article 302 power.

However, Article 303(2) carves out an exception: Parliament may, by law, authorise preference or discrimination if it declares that this is necessary to deal with a situation arising from scarcity of goods in any part of India. This lets the Union respond to genuine shortages without being blocked by the general non-discrimination rule.

State Powers Under Article 304

Article 304 allows a State legislature, notwithstanding Articles 301 and 303, to:

Clause	What it permits
304(a)	Tax goods imported from other States (or Union territories) at a rate similar to that on locally made goods — but without discriminating against the imported goods
304(b)	Impose reasonable restrictions on trade, commerce or intercourse with or within that State, if required in the public interest

A proviso attached to Article 304(b) requires that no Bill or amendment for this purpose can be introduced or moved in a State legislature without the previous sanction of the President. This gives the Union a check over State-level restrictions on trade before they are even tabled, reflecting the quasi-federal design of Centre-State relations.

Saving of Existing Laws — Article 305

Article 305 protects existing laws from being struck down under Articles 301 and 303, except to the extent the President may otherwise direct. It also preserves laws made before the Constitution (Fourth Amendment) Act, 1955 relating to State monopolies referred to in Article 19(6)(ii), and allows Parliament or a State legislature to continue legislating on such monopoly matters.

Article 306 — Omitted

Article 306, which had allowed certain former Part B States to impose restrictions on trade and commerce, was omitted by the Constitution (Seventh Amendment) Act, 1956, once the reorganisation of States rendered the provision redundant.

Article 307 — Authority to Carry Out Part XIII

Article 307 empowers Parliament to appoint an authority to carry out the purposes of Articles 301 to 304 and to confer on that authority the powers and duties considered necessary. During the framing of the Constitution, members such as T.T. Krishnamachari argued — drawing on the Australian constitutional model — for an Inter-State Commission to adjudicate trade disputes and oversee free intercourse among the units. In practice, however, no such authority has been appointed under Article 307 so far.

Significance for Indian Federalism

Part XIII reflects a deliberate constitutional choice to treat India as an integrated economic union rather than a loose federation of separate markets. Article 301 sets the default rule of freedom; Articles 302-305 supply the calibrated exceptions that let the Union and the States regulate trade for public interest, revenue, and emergency reasons without dismantling the underlying unity of the domestic market. This framework has been central to debates on inter-State check posts, entry taxes, and — more recently — the constitutional discussion around GST as a measure to remove trade barriers between States.
