Freedom of Trade, Commerce and Intercourse (Articles 301-307)

Freedom of trade, commerce and intercourse across India is guaranteed by Part XIII of the Constitution, Articles 301 to 307. These provisions bar the Union and the States from erecting internal trade barriers, so that goods, people and business move across State lines as though the country were a single economic unit, while still allowing regulated, public-interest restrictions. Part XIII is the constitutional foundation of India's internal economic integration.

Article 301: The Basic Guarantee

Article 301 declares that "trade, commerce and intercourse throughout the territory of India shall be free," subject to the other provisions of Part XIII. The freedom is not confined to inter-State movement — it extends to trade carried on entirely within a single State (intra-State trade) too. Its object is to break down the border barriers that could otherwise be erected between States, so that trade flows across the country as one economic unit. This freedom is not absolute; it operates subject to the restrictions permitted under Articles 302 to 305.

Article 302: Parliament's Power to Restrict

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's territory — where required in the public interest. This lets the Union regulate trade for larger public purposes, such as public health or equitable distribution of scarce goods, without such a law being invalid merely because it curtails free movement of trade.

Article 303: The Non-Discrimination Rule

Article 303(1) checks both Parliament and State Legislatures: notwithstanding Article 302, neither can make a law giving preference to one State over another, or discriminating between States, merely by virtue of a trade-and-commerce entry in any List of the Seventh Schedule. This stops the trade entries in the Union, State or Concurrent Lists from becoming a route to regional favouritism.

Article 303(2) carves an exception: Parliament may make a law giving preference or authorising discrimination between States if the law itself declares this necessary to deal with a scarcity of goods in any part of India. Parliament alone retains this discretion — States cannot invoke it.

Article 304: State Powers over Trade and Commerce

Article 304 operates notwithstanding Articles 301 and 303 and lets a State Legislature, by law:

• (a) tax goods imported from other States or Union territories, provided similar goods made within that State bear the same tax — so imported and local goods are not discriminated against; and
• (b) impose reasonable restrictions on trade, commerce or intercourse with or within that State, as required in the public interest.

A proviso to clause (b) requires that no such Bill can be introduced in a State Legislature without the previous sanction of the President — one way the Centre retains oversight over State laws that could fragment the national market.

Article 305: Saving of Existing Laws

Article 305 protects laws pre-dating the relevant provisions: nothing in Articles 301 and 303 affects any existing law, except so far as the President may by order otherwise direct. It also saves laws made before the Constitution (Fourth Amendment) Act, 1955, relating to matters under Article 19(6)(ii) — laws letting the State carry on any trade, business, industry or service to the exclusion (complete or partial) of citizens, i.e., State monopolies.

Articles 306 and 307

Article 306, which once let certain former Part B States impose trade restrictions, was omitted by the Constitution (Seventh Amendment) Act, 1956, after State reorganisation. Article 307 authorises Parliament to appoint, by law, an authority to carry out the purposes of Articles 301 to 304 — a body that could administer and adjudicate questions of inter-State and intra-State trade freedom. In the Constituent Assembly, T.T. Krishnamachari argued for such an Inter-State Commission, drawing on the Australian precedent, to regulate trade between the units and adjudicate disputes. In practice, no authority has so far been appointed under Article 307.

Judicial Interpretation

In Bengal Immunity Co. v. State of Bihar (1955), the Supreme Court overruled its own earlier majority view in State of Bombay v. United Motors, revisiting how far a State can tax the sale or purchase of goods in the course of inter-State trade — illustrating how the line between legitimate State taxation and an impermissible burden on free trade has been worked out case by case. The presidential-sanction proviso under Article 304(b) was itself tested before the Supreme Court in Hoechst Pharmaceuticals v. State of Bihar (1983), a case arising directly from this procedural safeguard in Part XIII.

Part XIII vs Article 19(1)(g)

Article 19(1)(g), a Fundamental Right, guarantees citizens the right to practise any profession or carry on any occupation, trade or business, subject to reasonable restrictions under Article 19(6). Part XIII is a distinct guarantee of free trade, commerce and intercourse as a structural feature of India's economic union — not confined to citizens, and protecting the flow of trade itself rather than an individual's right to an occupation. The two run in parallel but serve different ends: one protects a citizen's livelihood, the other protects India's integrity as a single trading area.

Contemporary Relevance

Following the 101st Amendment, Article 269A provides that GST on inter-State supplies is levied and collected by the Union and apportioned between the Union and the States on the GST Council's recommendation — a modern extension of the inter-State trade question Part XIII first addressed. Entry 33 of the Concurrent List further empowers Parliament and State Legislatures to legislate on trade and commerce in products of industries declared expedient in the public interest, plus foodstuffs, cattle fodder, raw cotton and raw jute; Entry 33A covers weights and measures, except the establishment of standards.
