The Constitution ordinarily assigns matters in the:
State List
to the State Legislatures.
However, Article 252 provides a mechanism through which:
Parliament
can legislate on a State List matter when:
Two or More State Legislatures Request Parliament to Do So
This provision represents an important form of:
Cooperative Federalism
The basic formula is:
Article 252 → State Request → Parliament Legislates on State List
Article 252 deals with:
Legislation for two or more States by consent and adoption by any other State
It allows Parliament to make laws on a matter in the:
State List
when the required State Legislatures pass resolutions requesting Parliament to enact such legislation.
States may sometimes face a common policy problem where:
Instead of each State passing separate laws, the Constitution permits:
Parliamentary Legislation at the Request of States
Thus:
State Initiative → Parliamentary Legislation
Article 252 requires:
Two or More State Legislatures
to pass resolutions requesting Parliament to legislate.
Therefore:
One State Alone → Not Enough
Two or More States → Required
The State Legislatures pass resolutions stating that:
Parliament should legislate on the specified State List matter.
The resolution does not itself become the Parliamentary law.
The sequence is:
Two or More State Legislatures
↓
Pass Resolutions
↓
Request Parliament
↓
Parliament Enacts Law
5. Parliament's Role
Once the required State Legislatures pass resolutions:
Parliament
may enact the requested legislation.
The resulting law is:
An Act of Parliament
even though the original subject lies in the:
State List
6. Does Parliament Legislate Automatically?
No.
The Constitution gives Parliament the power to legislate after the required State resolutions.
The State resolutions are therefore the:
Constitutional Trigger
for Parliamentary legislation.
7. Other States Can Adopt the Law
After Parliament enacts the law, another State may adopt it by passing a:
Resolution in its Legislature
Such adoption extends the Parliamentary legislation to that State according to the constitutional framework.
Therefore:
Initial States
↓
Request Parliament
↓
Parliament Makes Law
↓
Other State
↓
Passes Similar Resolution
↓
Adopts Parliamentary Law
8. Importance of Adoption
Article 252 allows:
Flexible Federal Participation
States are not forced to adopt the Parliamentary legislation.
They can choose to:
Join Later
by passing the required resolution.
This makes Article 252 different from ordinary Union legislation.
Nature of Parliamentary Legislation
9. State List Matter Becomes Parliamentary Law
The subject remains constitutionally associated with the:
State List
but Parliament legislates because the States have requested it.
This does not mean the entire State List is transferred to Parliament.
It means:
Specific Subject + State Request → Parliamentary Legislation
10. Scope of the Request
The Parliamentary legislation is linked to:
The Matter Specified in the State Resolutions
Therefore, Article 252 is:
Matter-Specific
rather than:
General Transfer of State Legislative Power
11. Article 252 and State Autonomy
Article 252 does not permanently eliminate State autonomy.
Instead, States voluntarily choose:
Parliamentary Uniformity
over:
Separate State Legislation
on the particular matter.
Thus:
State Autonomy → Voluntarily Shared
Amendment and Repeal
12. Who Can Amend the Law?
This is one of the most important UPSC Prelims points.
A law enacted by Parliament under Article 252 can be:
Amended or Repealed Only by Parliament
The individual State Legislatures cannot independently amend or repeal the Parliamentary law.
13. Why States Cannot Amend It
Once Parliament legislates under Article 252, the law becomes:
Parliamentary Legislation
The constitutional arrangement does not allow an individual State Legislature to amend that Parliamentary statute directly.
Therefore:
State Request → Parliament Makes Law → Parliament Amends/Repeals
14. Can States Withdraw Individually?
A State cannot simply repeal the Parliamentary law through its own State legislation.
If the State wants the law altered or removed, the constitutional mechanism requires:
Parliamentary Action
for amendment or repeal.
This preserves the uniform legislative framework created through Article 252.
Article 252 and Federalism
15. Cooperative Federalism
Article 252 is a classic example of:
Cooperative Federalism
because:
States initiate the process
Parliament provides the common legislation
Other States can voluntarily join
The relationship is therefore:
State Initiative + Union Legislation + State Adoption
16. Why It Is Federal in Character
Unlike unilateral Parliamentary intervention, Article 252 begins with:
State Consent
This demonstrates that Indian federalism is not based only on separation.
It also provides mechanisms for:
Cooperation + Coordination
17. Flexibility
Article 252 allows different States to:
Request common legislation
Adopt it later
Remain outside initially
This provides:
Policy Flexibility
while allowing:
Uniformity Where States Desire It
Article 252 vs Article 249
18. Key Difference
Article 249
Parliament legislates on State List because:
National Interest
Trigger:
Rajya Sabha Resolution
Article 252
Parliament legislates because:
Two or More State Legislatures Request It
Trigger:
State Resolutions
Memory:
249 → National Interest
252 → State Request
19. Comparison Table
Feature Article 249 Article 252
Basis National Interest State Consent

Subject State List State List
Nature Exceptional Union intervention Cooperative legislation
Initial initiative Rajya Sabha States
Other States Not required Can adopt later

Article 252 vs Article 250
20. Article 252
Operates because:
States Request
It does not require:
National Emergency
21. Article 250
Operates because:
National Emergency
It does not require:
State Legislative Requests
Memory:
250 → Emergency
252 → Consent
Article 252 vs Article 253
22. Article 252
Based on:
Domestic State Consent
23. Article 253
Based on:
International Obligations
Therefore:
252 → State Request
253 → International Agreement
Article 252 vs Article 356
24. Article 252
States voluntarily request Parliamentary legislation.
25. Article 356
Parliament may exercise legislative powers of a State Legislature during:
President's Rule
Article 356 is therefore:
Constitutional Intervention
while Article 252 is:
Cooperative Consent
Historical and Practical Importance
26. Common Legislative Framework
Article 252 is particularly useful when several States face:
The Same Legislative Problem
and want:
Common Legal Standards
This avoids the need for identical legislation to be separately enacted by every participating State.
27. Examples
An important historical example is:
Wild Life (Protection) Act, 1972
Parliament's enactment in this area involved the constitutional mechanism through which States requested Parliamentary legislation on the subject.
Another well-known example is:
Water (Prevention and Control of Pollution) Act, 1974
which was enacted through the Article 252 route.
These examples illustrate how States can voluntarily seek:
Common Parliamentary Legislation
on matters within the State field.
28. Why Such Legislation Can Be Useful
Article 252 can help achieve:
Uniform standards
Administrative coordination
Easier implementation
Common regulatory mechanisms
Reduced legislative duplication
Therefore:
Common Problem → Common Law
where States consider it desirable.
Limitations
29. Requires State Participation
Parliament cannot normally initiate Article 252 legislation without the required:
State Resolutions
Therefore, the mechanism depends on:
State Consent
30. Not Automatically Applicable to All States
A State that does not initially participate is not automatically bound merely because other States requested the legislation.
It can later adopt the law through the constitutional mechanism.
Thus:
Article 252 → Participatory Federalism
31. Limited Flexibility After Enactment
Once Parliament has enacted the law, an individual State cannot independently amend the Parliamentary statute.
This can reduce:
State Legislative Flexibility
after common legislation has been adopted.
32. Balancing Uniformity and Autonomy
Article 252 involves a trade-off:
Uniformity
versus:
State Legislative Independence
States effectively choose common legislation where the benefits of uniformity outweigh the value of separate laws.
Article 252 and Judicial Review
33. Can an Article 252 Law Be Challenged?
Yes.
Parliamentary legislation under Article 252 remains subject to:
Constitutional Limitations
and:
Judicial Review
The law may be challenged for:
Violation of Fundamental Rights
Constitutional invalidity
Procedural constitutional defects
Other grounds recognised by law
34. Article 252 Is Not Unlimited Parliamentary Power
Parliament's power under Article 252 exists because:
The Constitution Authorises It
Therefore:
State Request → Constitutional Power
not:
State Request → Unlimited Power
Article 252 and State Legislatures
35. Role of State Legislatures
State Legislatures perform the initiating role by:
Passing Resolutions
They do not directly enact the common law under Article 252.
The roles are:
State Legislatures
→ Request
Parliament
→ Legislate
Other States
→ Adopt
36. Difference Between Resolution and Law
The State Legislature passes a:
Resolution
Parliament passes an:
Act
This distinction is important.
State Resolution
Requests Parliamentary legislation.
Parliamentary Act
Creates the common legal framework.
UPSC Prelims Facts
37. Important Facts
Article 252 allows Parliament to legislate on State List matters at the request of two or more State Legislatures.
The mechanism is based on State consent.
At least two State Legislatures must pass resolutions requesting Parliament to legislate.
The State Legislature does not itself enact the common law through Article 252.
Parliament enacts the resulting law.
Other States can adopt the Parliamentary law later by passing similar resolutions.
A State cannot independently amend or repeal a Parliamentary law enacted under Article 252.
Such laws can be amended or repealed only by Parliament.
Article 252 is an example of cooperative federalism.
Article 252 differs from Article 249 because Article 249 is based on national interest and a Rajya Sabha resolution.
Article 252 differs from Article 250 because Article 250 operates during National Emergency.

Mains Perspective
52. Cooperative Federalism
Article 252 is one of the clearest examples of:
Cooperative Federalism
because the Union and States work together rather than one level unilaterally overriding the other.
The process is:
State Initiative → Union Legislation → Voluntary State Adoption
53. Advantages
Uniformity
Provides common rules across participating States.
Efficiency
Avoids separate legislation by every State.
Coordination
Useful where problems cross State boundaries.
Flexibility
Other States can adopt the law later.
Respect for State Consent
The process begins with the participating States.
54. Limitations
Dependence on Consensus
Two or more States must agree before Parliament can act under Article 252.
Reduced Flexibility After Adoption
States cannot independently amend the Parliamentary law.
Uneven Participation
Different States may adopt the legislation at different times.
Central Legislative Dependence
Once the common law exists, subsequent modification depends on Parliament.
55. Federal Significance
Article 252 demonstrates that India's federalism is not based solely on:
Separation
but also on:
Coordination
It provides a mechanism for States to voluntarily share legislative space with Parliament when common legislation is considered beneficial.
56. Reform Perspective
The effectiveness of Article 252 can be improved through:
Greater Inter-State Consultation
States should identify areas where common legislation would provide genuine benefits.
Cooperative Policy Design
Participating States should contribute to the design of Parliamentary legislation.
Flexible Implementation
Common legislation should allow reasonable State-level administrative flexibility.
Regular Review
Participating States and Parliament can periodically review whether the common framework remains appropriate.
57. Conclusion
Article 252 provides a unique mechanism through which:
States Invite Parliament to Legislate
on matters ordinarily within the:
State List
The key sequence is:
Two or More State Legislatures
→ Pass Resolutions
→ Request Parliament
→ Parliament Enacts Law
→ Other States May Adopt
→ Parliament Alone Amends or Repeals
The UPSC formula is:
252 → State Request → Parliament Legislates
The broader principle is:
State Consent + Parliamentary Action + Voluntary Adoption = Cooperative Federalism
