Territorial jurisdiction of Parliament and State Legislatures refers to the:
Geographical extent within which their laws may operate.
The principal constitutional provision is:
Article 245
It establishes the basic territorial scope of legislative power.
The broad rule is:
Parliament → Whole or any part of India
State Legislature → Whole or any part of the State
The Constitution also recognises the possibility of:
Extra-Territorial Operation of Parliamentary Laws
while State legislation is subject to the doctrine of:
Territorial Nexus
The main provision is:
Article 245
Related provisions include:
Article 246 → Distribution of legislative subjects
Seventh Schedule → Union, State and Concurrent Lists
Article 254 → Repugnancy
Therefore:
Article 245 → Where a law can operate
Article 246 → What a Legislature can legislate on
This distinction is extremely important for UPSC.
Under Article 245, Parliament may make laws for:
The whole of India
or:
Any part of India
Therefore, Parliament may enact:
Memory:
Parliament → Whole India or Part of India
Article 245 expressly provides that:
No law made by Parliament shall be deemed invalid on the ground that it would have extra-territorial operation.
This gives Parliament a broader territorial reach than State Legislatures.
Extra-territorial operation means that a Parliamentary law may produce:
Legal consequences outside India.
A law has extra-territorial operation when:
The existence of an extra-territorial element does not by itself invalidate Parliamentary legislation.
However:
Parliamentary Power ≠ Unlimited Global Jurisdiction
The law must still comply with the Constitution.
Parliament may enact laws affecting:
The validity depends on:
Constitutional Authority + Legislative Competence + Relevant Connection
Parliament's power is not limited to making laws applicable uniformly throughout India.
It can create:
Region-Specific Legislative Regimes
where constitutionally permissible.
Thus:
Whole India ≠ Mandatory Uniform Application
Under Article 245, a State Legislature may make laws for:
The whole or any part of that State
For example:
Kerala Legislature → Kerala
Maharashtra Legislature → Maharashtra
A State Legislature ordinarily cannot claim the same unrestricted extra-territorial power as Parliament.
A State law may nevertheless have effects outside the State in certain circumstances.
The key constitutional doctrine is:
Territorial Nexus
The State must have a:
Sufficient Connection
with the subject matter of the legislation.
Territorial nexus means:
A real and sufficient connection between the State and the subject matter of the law.
It prevents a State Legislature from regulating matters that have:
No meaningful connection with the State.
Without territorial nexus, a State Legislature could potentially attempt to regulate:
This would undermine:
Therefore:
Territorial Nexus → Constitutional Limitation
For a State law affecting matters beyond its territory, there should broadly be:
A genuine connection between:
State + Subject Matter
The connection must be:
Real + Sufficient
It should not be merely:
Artificial + Illusory
Suppose a company is registered outside a State but:
The State may, subject to constitutional competence and the relevant law, regulate or tax aspects sufficiently connected with the State.
The core question is:
Is there a sufficient territorial nexus?
Territorial nexus has historically been especially important in:
Taxation
A State may impose a tax where there is a sufficient connection between:
Taxable Subject + State
However:
Territorial Nexus Does Not Create Taxing Power
The State must first have:
Constitutional Taxing Competence
A business may operate partly outside a State but maintain:
within the State.
If the constitutional taxing provision covers the activity and sufficient territorial nexus exists, the State may regulate or tax the relevant activity.
Thus:
Taxing Power + Territorial Nexus
must coexist.
Two separate questions must be answered:
Does the State Legislature have subject-matter competence?
Does the legislation have sufficient territorial connection?
Therefore:
State Law
↓
Subject within State Legislative Competence?
↓
Yes
↓
Territorial Nexus?
↓
Yes
↓
Possible Constitutional Validity
A territorial connection cannot cure:
Lack of Legislative Competence
16. Article 245 vs Article 246
This distinction is a major UPSC Prelims point.
Article 245
Deals mainly with:
Territorial Extent
Article 246
Deals mainly with:
Distribution of Legislative Subjects
Memory:
245 → WHERE
246 → WHAT
Territorial Nexus vs Other Doctrines
17. Territorial Nexus vs Pith and Substance
Territorial Nexus
Asks:
Is there a sufficient geographical connection?
Pith and Substance
Asks:
What is the true nature and character of the legislation?
Memory:
Nexus → Connection
Pith → Substance
18. Territorial Nexus vs Repugnancy
Territorial Nexus
Deals with:
Geographical Connection
Repugnancy
Deals with:
Conflict between Parliamentary and State laws
under Article 254 in the Concurrent field.
Memory:
Nexus → Territory
Repugnancy → Conflict
19. Territorial Nexus vs Colourable Legislation
Territorial Nexus
Tests:
Connection with State
Colourable Legislation
Tests:
Whether Legislature has indirectly done what it cannot directly do
Judicial Role
20. Judicial Review
Courts can examine whether:
Parliament has legislative competence
State Legislature has legislative competence
Territorial nexus exists
Fundamental Rights are violated
Other constitutional provisions are violated
Therefore:
Territorial Jurisdiction → Subject to Judicial Review
21. Role of Supreme Court
The Supreme Court interprets:
Article 245
Article 246
Seventh Schedule
Territorial Nexus
Legislative competence
It helps maintain:
Federal Balance
between Union and States.
Important Cases
22. State of Bombay v. R.M.D. Chamarbaugwala
This is an important case concerning:
Territorial Nexus
The Supreme Court recognised that State legislation may have effects beyond the State where a sufficient territorial connection exists.
Memory:
R.M.D. Chamarbaugwala → Territorial Nexus
23. State of Bihar v. Charusila Dasi
The case is important for:
Territorial Nexus + State Legislative Power
The Court considered the relationship between State legislation and property located partly outside the State.
Memory:
Charusila Dasi → Territorial Nexus
24. A.H. Wadia v. Income Tax Commissioner
The case is relevant to:
Extra-Territorial Operation of Legislative Powers
It helps distinguish the broader territorial power of Parliament from the limitations applicable to State Legislatures.
Memory:
A.H. Wadia → Extra-Territoriality
Parliament vs State Legislature
25. Comparison Table

Subject-matter competence Articles 246 etc. Articles 246 etc.
Judicial review Yes Yes
Territorial Jurisdiction and Federalism
26. Federal Significance
Article 245 reflects India's federal arrangement.
Parliament has:
Nationwide Legislative Reach
while State Legislatures have:
State-Level Legislative Reach
This creates:
Geographical Division of Legislative Authority
27. State Autonomy
Territorial jurisdiction protects State legislative autonomy by preventing:
Unrestricted Extra-State Regulation
At the same time, territorial nexus allows States to regulate activities sufficiently connected with them.
Thus:
State Autonomy + Practical Regulatory Reach
28. National Unity
Parliament's nationwide jurisdiction helps ensure:
National legal uniformity where necessary
Economic integration
National security
International obligations
Thus:
Parliamentary Territorial Power → National Integration
Inter-State Transactions
29. Cross-Border State Activities
Modern economic activities can span:
Multiple States
Multiple countries
Digital platforms
Cross-border transactions
This creates difficult questions regarding:
Which Legislature Can Regulate?
The answer may depend on:
Subject-matter competence
Territorial nexus
Specific constitutional provisions
Inter-State trade provisions
GST framework
30. GST and Territorial Jurisdiction
GST has a special constitutional arrangement under:
Article 246A
Parliament and State Legislatures have GST legislative powers subject to the Constitution.
For:
Inter-State Supply
Parliament has exclusive legislative power under the constitutional GST framework.
Therefore:
GST → Special Constitutional Framework
rather than reliance solely on general territorial nexus principles.
31. Article 301 and Trade
Articles:
301–307
deal with:
Freedom of Trade, Commerce and Intercourse
throughout India.
State laws affecting inter-State commerce may therefore be subject to additional constitutional restrictions.
Territorial Jurisdiction and Fundamental Rights
32. Constitutional Limits
Even where territorial nexus exists, a State law must comply with:
Fundamental Rights
Legislative competence
Repugnancy rules
Other constitutional provisions
Therefore:
Territorial Nexus ≠ Automatic Validity
33. Article 14
Territorial classifications may be constitutionally valid where justified.
However, territorial distinctions cannot be:
Arbitrary or Unreasonable
Thus:
Territorial Regulation → Subject to Equality

Mains Perspective
47. Constitutional Balance
Territorial jurisdiction balances:
Nationwide Legislative Authority
with:
State Territorial Autonomy
Parliament requires broad territorial reach to deal with issues of national importance.
State Legislatures require sufficient territorial authority to address:
Local conditions
Regional economies
State administration
48. Importance in Modern Governance
Traditional territorial boundaries are becoming less clear because of:
Digital platforms
Online commerce
Financial transactions
Interstate business
Cross-border services
This makes territorial jurisdiction increasingly important for:
Regulation + Taxation + Federal Coordination
49. Challenges
Digital Economy
Physical location may not match economic activity.
Inter-State Transactions
A single transaction may involve several States.
Taxation
Multiple territorial connections may arise.
Regulatory Overlap
Both Union and State institutions may claim authority.
Federal Disputes
Different levels of government may disagree over legislative competence.
50. Reform Perspective
The framework can be strengthened through:
Clear Legislative Drafting
Specify territorial reach clearly.
Inter-State Coordination
Use cooperative institutions to manage cross-border issues.
Modern Legal Frameworks
Adapt laws to digital and platform-based activities.
Constitutional Compliance
Ensure territorial regulation remains within legislative competence.
Judicial Clarity
Develop consistent principles for emerging forms of economic activity.
51. Conclusion
Territorial jurisdiction answers the question:
Where can a Legislature's law operate?
The core provision is:
Article 245
The basic rule is:
Parliament → Whole or Any Part of India
State Legislature → Whole or Any Part of the State
For State laws with extra-State effects:
Territorial Nexus
is the key doctrine.
The most important UPSC distinction is:
Article 245 → WHERE
Article 246 → WHAT
Territorial Nexus → Sufficient State Connection
The broader principle is:
Territorial Authority + Legislative Competence + Constitutional Limits = Valid Legislative Jurisdiction
