Constitutional Law
Freedom of Trade, Commerce and Intercourse
Understand Articles 301 to 307, restrictions on trade across India, discriminatory State taxes and the current rule after Jindal Stainless.
The short answer
Part XIII protects the free flow of trade across India while permitting carefully structured public-interest regulation and non-discriminatory taxation.
How Part XIII creates an economic union
Articles 301 to 307 seek to prevent internal economic barriers while preserving limited legislative power to regulate trade in the public interest.
Article 301
Trade, commerce and intercourse throughout India shall be free, subject to the other provisions of Part XIII. The guarantee covers inter-State and intra-State movement, but it is not an absolute freedom from every law or tax.
Parliament under Article 302
Parliament may impose restrictions in the public interest. Its power remains subject to Article 303, which generally prohibits preference to one State or discrimination between States.
Scarcity exception
Parliament may depart from Article 303 where a law declares that a situation arising from scarcity of goods in any part of India makes the departure necessary.
State power under Article 304
A State may impose a non-discriminatory tax on imported goods under Article 304(a). It may also impose a reasonable public-interest restriction under Article 304(b), but the Bill requires the President's previous sanction.
The modern problem-solving test
Start with the effect of the measure, then identify which constitutional permission is available.
Does the law impede trade?
A direct barrier, prohibition, discriminatory burden or other substantial impediment may engage Article 301. Ordinary regulation that facilitates orderly trade does not automatically become a restriction.
Taxes are not restrictions by default
After Jindal Stainless, a tax does not violate Article 301 merely because it has a financial effect. The central tax inquiry under Article 304(a) is whether imported goods suffer discrimination compared with similar local goods.
Article 304(a) and 304(b) do different work
Clause (a) addresses discriminatory taxation. Clause (b) permits reasonable public-interest restrictions subject to its procedural condition. A student should not merge the two routes.
Article 19 remains separate
Article 301 protects the national flow of trade, while Article 19(1)(g) protects a citizen's occupational freedom subject to Article 19(6). A measure may require analysis under both provisions.
The constitutional map under Articles 301 to 307
Part XIII protects an Indian economic union while permitting carefully structured regulation and public-interest restrictions.
Article 301
Trade, commerce and intercourse throughout India shall be free, subject to the other provisions of Part XIII. The guarantee addresses barriers to movement and commercial intercourse across the national market.
Articles 302 and 303
Parliament may impose public-interest restrictions, but Union and State law ordinarily cannot prefer one State or discriminate between States. Parliament has a narrow scarcity-based exception under Article 303(2).
Article 304(a)
A State may tax goods imported from another State only without discrimination against similar goods manufactured or produced within the State.
Article 304(b)
A State may impose reasonable public-interest restrictions, but the Bill or amendment requires the President's previous sanction before introduction in the State Legislature.
The rule after Jindal Stainless
The nine-judge decision changed how taxes are analysed under Article 301 and rejected the earlier compensatory-tax doctrine as the controlling test.
A non-discriminatory tax does not become a restriction on trade merely because it creates a financial burden. Article 304(a) directly tests whether imported goods suffer discriminatory taxation compared with similar local goods.
The inquiry compares the legal and practical tax burden on imported and domestic goods. Classification, exemptions, rebates and valuation rules may reveal discrimination even where the headline rate appears equal.
Regulatory measures that directly impede trade may still engage Article 301 and require justification under the relevant provision. Students should therefore separate a tax challenge from a non-tax barrier before choosing the constitutional test.
How to test a trade restriction
A disciplined answer identifies the measure, burden, constitutional actor and saving provision in that order.
Characterise the measure
Decide whether it is a tax, licence, quota, transport condition, border check, monopoly or direct movement restriction. Different measures engage different parts of Part XIII.
Find the burden
Show how the law affects market access, movement or competition. An ordinary regulatory requirement is not automatically a constitutional barrier.
Choose the saving rule
For parliamentary restrictions use Article 302 and 303. For State taxes use Article 304(a), and for other State restrictions use Article 304(b), including reasonableness and previous sanction.
Check saved arrangements
Article 305 addresses specified existing laws and State monopolies, while Article 307 permits an authority to carry out Part XIII purposes.
From Atiabari Tea to Jindal Stainless
The case sequence shows why older notes on compensatory tax must be updated.
Atiabari Tea
The Court focused Article 301 on measures that directly and immediately restrict trade, placing movement burdens within the constitutional guarantee.
Automobile Transport
The decision developed the idea that regulatory and compensatory charges facilitating trade could fall outside the prohibition, producing a doctrine later expanded in tax cases.
Jindal Stainless
The larger Bench rejected compensatory tax as the governing constitutional doctrine and centred State tax review on discrimination under Article 304(a).
Current exam rule
Use older cases to explain development, but apply Jindal Stainless for the present treatment of non-discriminatory taxes and imported-versus-local goods.
Worked problem: a State entry tax
Assume imported goods pay a facially equal rate, but local manufacturers receive a rebate unavailable to outside goods.
Compare the effective burden after rebate rather than stopping at the nominal rate. If similar local goods receive a material advantage, Article 304(a) discrimination may arise even though the charging provision uses identical language.
Identify whether the difference rests on origin or on a neutral factor available equally to imported goods. The State may defend a genuine non-origin classification, but the court examines practical operation and not only drafting form.
If the measure is a non-tax restriction, shift to Article 304(b), test public interest and reasonableness, and confirm the President's previous sanction. Do not use Article 304(a) as a universal test for every trade barrier.
Leading cases and what they establish
Read each authority for the proposition it proves, the legal question it answers and the reasoning that supports the result.
Atiabari Tea Co. Ltd. v. State of Assam
AIR 1961 SC 232
Facts: Tea grown in Assam was transported through the State for sale outside it, and Assam imposed a tax on goods carried by road or inland waterways.
Legal question: Did a tax operating directly on movement of goods restrict the freedom protected by Article 301?
Held: A measure whose direct and immediate effect restricts the movement of trade engages Article 301 and must find support within Part XIII.
Reasoning: The direct and immediate effect on trade movement engaged Article 301. A restriction had to satisfy the relevant permission and procedure within Part XIII.
Why it matters: Use it for the origin of the direct and immediate effect test.
Read the judgmentAutomobile Transport (Rajasthan) Ltd. v. State of Rajasthan
AIR 1962 SC 1406
Facts: Transport operators challenged Rajasthan's tax on motor vehicles using roads within the State as an unconstitutional barrier to trade.
Legal question: Does every regulatory charge connected with the use of trading facilities violate Article 301?
Held: Regulatory measures that facilitate trade were distinguished from restrictions, and the Court developed the older compensatory-tax approach.
Reasoning: The Court distinguished measures facilitating orderly trade from restrictions and developed the compensatory-tax approach, which later doctrine has reformulated.
Why it matters: Use it to explain doctrinal development, then state that Jindal Stainless later reformulated the tax analysis.
Read the judgmentJindal Stainless Ltd. v. State of Haryana
(2017) 12 SCC 1
Facts: A large group of challenges questioned State entry taxes on goods entering local areas and the constitutional treatment of taxation under Part XIII.
Legal question: Is every tax a restriction on trade, and what does Article 304(a) prohibit?
Held: A tax is not a restriction under Article 301 merely because it is a tax. Article 304(a) prohibits discriminatory taxation of imported goods, and the compensatory-tax doctrine is not the controlling test.
Reasoning: Taxation is not a restriction merely by nature. Article 304(a) permits equal taxation but prohibits discrimination against imported goods compared with similar locally produced goods.
Why it matters: Use it for the present approach to taxation, discrimination and Articles 301 and 304(a).

Questions students ask
Does Article 301 ban all entry taxes?
No. A tax is not a restriction merely because it raises cost. The key State-tax question is whether imported goods are discriminated against contrary to Article 304(a).
Can a State impose a reasonable trade restriction?
Yes. Article 304(b) permits a reasonable restriction in the public interest, subject to the requirement of previous presidential sanction for introducing or moving the Bill.
Does Article 301 prohibit every tax on trade?
No. Jindal Stainless holds that a non-discriminatory tax is not a restriction merely because it imposes a financial burden. Discriminatory State taxation is tested under Article 304(a).
Does an Article 304(b) Bill need presidential assent or previous sanction?
The proviso requires the President's previous sanction before the Bill or amendment is introduced. This procedural condition should not be confused with assent after passage.
Is the compensatory-tax doctrine still the main test?
No. Jindal Stainless rejected it as the governing constitutional test for taxation. The focus is now the structure of Part XIII, especially non-discrimination under Article 304(a).
