Articles:
302 + 303 + 304
form the core constitutional framework for:
Restrictions on the Freedom of Trade, Commerce and Intercourse
guaranteed under:
Article 301
These provisions balance:
Freedom of Internal Trade
with:
Public Interest + Non-Discrimination + Legitimate State Regulation
The basic constitutional structure is:
Article 301 → Freedom
Article 302 → Parliament's Restriction Power
Article 303 → No Preference or Discrimination
Article 304 → State Powers
The central principle is:
Economic Unity + Constitutionally Permitted Restrictions = Integrated Federal Market
Articles 302, 303 and 304 are contained in:
Part XIII
of the Constitution.
Part XIII covers:
Articles 301–307
The framework is:
301
→ Freedom of Trade, Commerce and Intercourse
302
→ Parliament's Restrictions
303
→ Preference and Discrimination
304
→ State Restrictions
305
→ Saving of Existing Laws and State Monopolies
306
→ Omitted
307
→ Authority
2. Article 302 — Parliament's Power to Restrict Trade
Article 302 empowers:
Parliament
to impose restrictions on:
Trade + Commerce + Intercourse
between:
States
or:
within the territory of India
when such restrictions are considered necessary:
In the Public Interest
3. Purpose of Article 302
Article 302 recognises that:
Economic Freedom Cannot Be Absolute
National circumstances may require restrictions for:
Public welfare
Regulation of supply
Economic stability
Scarcity
Market management
National interests
Thus:
Article 302 = Union-Level Regulatory Power
4. Who Can Act Under Article 302?
The power belongs to:
Parliament
It is not a power granted by Article 302 to:
State Legislatures
UPSC Trap
"Article 302 empowers States to restrict inter-State trade."
False
Article 302 → Parliament
5. Public Interest Under Article 302
The Constitution uses the expression:
Public Interest
as the basis for restrictions.
The term is broad and may encompass:
Economic welfare
Supply security
Public needs
Market stability
National economic objectives
However:
Public Interest Does Not Mean Unlimited Power
The restriction remains subject to:
Constitutional Limits
6. Article 302 and Article 301
The relationship is:
Article 301
→ Freedom
Article 302
→ Parliament May Restrict
→ Public Interest
Therefore:
Article 302 Is a Constitutional Qualification to Article 301
7. Article 303 — Prohibition of Preference and Discrimination
Article 303 seeks to prevent:
Preferential or Discriminatory Economic Legislation
between:
One State and Another
It applies to:
Parliament + State Legislatures
8. Article 303(1)
Article 303(1) provides that:
Parliament or a State Legislature
shall not have power to make any law giving:
Preference to One State Over Another
or:
Discrimination Between One State and Another
by virtue of:
Any Entry Relating to Trade and Commerce
9. Why Article 303 Exists
Without Article 303, States could attempt to create:
Local protectionism
Preferential treatment
Favourable market rules
Economic barriers against outside goods
This could weaken:
The Common National Market
Therefore:
Article 303 Protects Economic Equality Among States
10. Article 303 and State Protectionism
A State cannot generally use legislation to:
Favour Its Own State
at the expense of:
Other States
For example, a State should not create a trade rule whose purpose is:
Preferential Treatment for Local Goods
while disadvantaging:
Comparable Goods From Other States
11. Article 303(2) — Scarcity Exception
Article 303 contains an important exception.
Parliament may make a law giving:
Preference
or making:
Discrimination
if the law declares that it is necessary for dealing with a situation arising from:
Scarcity of Goods in Any Part of the Territory of India
12. Meaning of Scarcity Exception
The Constitution recognises that extraordinary circumstances may require:
Special Economic Treatment
For example:
Serious Shortage of Essential Goods
may justify Parliament adopting special measures for a particular region.
The purpose is:
Supply Security
rather than:
Permanent Regional Protectionism
13. Who Can Use the Scarcity Exception?
The special exception under:
Article 303(2)
is associated with:
Parliamentary Legislation
It is not a general power for:
State Protectionism
14. Article 303 — Important Distinction
The general rule is:
No Preference + No Discrimination
The exceptional situation is:
Scarcity of Goods
Thus:
Normal Situation
→ No Preference / Discrimination
Scarcity Situation
→ Parliament May Make Special Provision
15. Article 304 — State Powers
Article 304 provides:
Specific Powers to State Legislatures
despite the freedom guaranteed by:
Article 301
It contains:
Article 304(a)
and:
Article 304(b)
16. Article 304(a) — State Taxation
Article 304(a) permits a State Legislature to impose:
Tax on Goods Imported From Other States or Union Territories
subject to an important condition:
The Tax Must Not Discriminate
against goods imported from other States when compared with:
Similar Goods Produced in the State
17. Purpose of Article 304(a)
Article 304(a) recognises that:
State Taxation Is Necessary
but prevents:
Protectionist Taxation
Thus:
Taxation Permitted + Discriminatory Taxation Prohibited
18. Example of Article 304(a)
Suppose:
State A
produces a particular commodity locally and also receives the same commodity from:
State B
State A may impose a tax on the imported goods, but the tax cannot be structured so that:
Imported Goods Bear a Discriminatory Burden
compared with:
Comparable Local Goods
19. Article 304(a) and Equal Treatment
The underlying objective is:
Competitive Equality
Goods from another State should not be unfairly disadvantaged merely because they:
Cross a State Boundary
20. Article 304(b) — Reasonable Restrictions
Article 304(b) permits a State Legislature to impose:
Reasonable Restrictions
on:
Trade + Commerce + Intercourse
with or within that State:
In the Public Interest
21. Previous Presidential Sanction
A Bill proposing restrictions under:
Article 304(b)
cannot be introduced in the State Legislature without:
Previous Sanction of the President
This is a major:
UPSC Prelims Fact
22. Why Presidential Sanction Is Important
The requirement introduces:
Union-Level Constitutional Oversight
over State measures that may restrict:
Inter-State Trade and Commerce
It therefore reflects:
Strong-Centre Federalism
within the economic field.
23. Article 304(a) vs Article 304(b)
Article 304(a) Article 304(b)
State taxation State restrictions
Goods from other States/UTs Trade, commerce and intercourse
Non-discrimination Reasonable restriction
Tax measure Regulatory measure
No discriminatory burden Public interest
No Article 304(b) sanction requirement Previous Presidential sanction
Memory
304(a) → Tax
304(b) → Restriction
24. Article 302 vs Article 304
This is a high-value UPSC comparison.
Article 302 Article 304
Parliament State Legislature
Restriction power State taxation + restrictions
Public interest 304(a): taxation + 304(b): public interest
Union-level power State-level power
Memory:
302 → Parliament
304 → States
25. Article 303 vs Article 304
Article 303
Focuses on:
Preference + Discrimination
Article 304
Provides:
Specific State Powers
Therefore:
303 → Restrict Discrimination
304 → Permit Certain State Measures
26. Article 301–304 Relationship
The constitutional sequence can be remembered as:
301
→ Freedom
302
→ Parliament Can Restrict
303
→ No Preference / Discrimination
304
→ States Can Act Within Limits
This creates:
Controlled Economic Federalism
27. Restrictions Must Be Constitutionally Valid
Not every State restriction is automatically valid merely because:
Public Interest
is cited.
A measure must operate within:
The Specific Constitutional Requirements
of the relevant provision.
Therefore:
Public Interest ≠ Unlimited State Power
28. Protectionism vs Regulation
This distinction is central.
Protectionism
Designed to:
Protect Local Producers From Outside Competition
Regulation
Designed to:
Legitimately Govern Economic Activity
Examples of legitimate regulation can include:
Public health rules
Safety regulations
Consumer protection
Environmental standards
Transport regulation
Therefore:
Regulation ≠ Automatically Unconstitutional Restriction
29. Taxation vs Regulation
Taxation
Primarily seeks:
Revenue
Regulation
Primarily seeks:
Control of Economic Activity
Article 304 distinguishes these through:
304(a) + 304(b)
30. Article 304(b) and Public Interest
A State may seek to restrict trade for objectives such as:
Public safety
Public health
Environmental protection
Market regulation
Essential services
But the restriction must remain:
Reasonable
and:
In the Public Interest
with the required:
Previous Presidential Sanction
31. Article 303 and Scarcity
The Constitution specifically recognises:
Scarcity of Goods
as an exceptional circumstance.
This is different from:
Ordinary Local Protectionism
The scarcity exception is therefore intended for:
Exceptional Supply Conditions
32. Article 302 and Scarcity
Article 302 itself permits Parliament to impose restrictions:
In the Public Interest
Article 303 specifically provides the:
Scarcity Exception
for preferential or discriminatory legislation.
Thus:
Public Interest and Scarcity Are Related but Distinct Constitutional Concepts
33. Supreme Court Interpretation
The Supreme Court has developed important jurisprudence concerning:
Articles 301–304
Major cases include:
Atiabari Tea Co. v. State of Assam
Automobile Transport (Rajasthan) Ltd. v. State of Rajasthan
Jindal Stainless Ltd. v. State of Haryana
34. Atiabari Tea Co. v. State of Assam
The:
Atiabari Tea Case (1961)
examined whether a tax affecting the movement of goods could amount to a:
Restriction on Trade and Commerce
The case became a major foundation of:
Article 301 Jurisprudence
35. Automobile Transport Case
The:
Automobile Transport (Rajasthan) Ltd. Case (1962)
examined:
Regulatory Measures
and their relationship with:
Article 301
The case is important for understanding the distinction between:
Regulation
and:
Restriction
36. Jindal Stainless Case
The:
Jindal Stainless Ltd. v. State of Haryana
judgment is a major modern decision on:
Taxation + Article 301 + Article 304
The Supreme Court placed emphasis on:
Discriminatory Treatment
in assessing the constitutional validity of taxes affecting inter-State trade.
37. Case-Law Memory
Atiabari Tea
→ Article 301 + Movement
Automobile Transport
→ Regulation
Jindal Stainless
→ Taxation + Discrimination
38. Article 302 and National Economic Integration
Parliament's power under Article 302 helps address:
National shortages
Market instability
Supply disruptions
Public welfare needs
It ensures that:
National Economic Interests
can be protected where necessary.
39. Article 303 and National Market
Article 303 protects the:
Common Economic Space
by restricting:
State-to-State Preferential Treatment
This helps ensure:
Equal Market Access
40. Article 304 and State Autonomy
Article 304 recognises that States require:
Regulatory Space
to pursue:
Public welfare
State taxation
Public interest restrictions
But that space is:
Constitutionally Limited
41. Economic Federalism
Together, Articles 302–304 create:
Economic Federalism
where:
Union + States
retain powers but must respect:
National Economic Integration
42. GST Connection
The GST framework reinforces the broader objective of:
One Integrated Indian Market
Key provisions include:
Article 246A
Article 269A
Article 279A
The GST Council provides:
Union–State Fiscal Coordination
43. Article 301 + GST
Article 301 protects:
Freedom of Trade, Commerce and Intercourse
while GST seeks to reduce:
Internal Tax Fragmentation
Together they support:
National Market Integration
44. Modern Economic Integration
Economic integration today depends on:
Highways
Rail freight
Ports
Logistics
E-commerce
Digital taxation
National supply chains
Therefore:
Constitutional Economic Freedom + Modern Infrastructure
must operate together.
45. Challenges
Protectionist State Policies
States may try to:
Favour Local Producers
Regulatory Fragmentation
Different State regulations may increase:
Compliance Costs
Discriminatory Taxation
Can distort:
Competition
Infrastructure Bottlenecks
Can reduce:
Actual Inter-State Trade
Environmental Restrictions
May create tensions between:

Harmonised Standards
for:
Transport
Logistics
Product regulation

Strengthen:
Roads
Railways
Ports
Logistics parks
Warehouses
Digital freight systems
This transforms:
Constitutional Freedom
into:
Practical Economic Mobility

State taxation should maintain:
Equal Competitive Conditions
between:
Local Goods + Comparable Goods From Other States
50. Reform — Digital Internal Market
Strengthen:
E-invoicing
Digital permits
Interoperable systems
National logistics platforms
Common compliance systems
The goal is:

are the principal constitutional provisions governing:
Restrictions on Inter-State Trade and Commerce
Their relationship with Article 301 can be remembered as:
301 → Freedom
302 → Parliament's Restrictions
