When India became independent in 1947, it wasn’t a single, seamless nation. It was a patchwork of British provinces, princely states, and foreign-controlled enclaves — each with its own legal system, governance structure, and political history.
So, how did all these regions come under one Constitution, one flag, and one legal system?
The answer lies in a complex web of constitutional provisions, parliamentary Acts, and judicial interpretations that governed the merger and integration of territories into the Indian Union.
This blog unpacks the legal implications of merging territories under Indian law — what happens when a territory joins India, how its laws change, and what it means for the people living there.
🌍 Background: India’s Gradual Legal Unification

After independence, the Indian government faced the mammoth task of uniting 562 princely states and several foreign-controlled territories like Goa, Pondicherry, and Dadra & Nagar Haveli.
While the political process of merger was handled through diplomacy and agreements, the legal process required something more enduring — the extension of the Indian Constitution and laws to these newly acquired territories.
Thus began a multi-decade legal journey involving:
- Constitutional amendments to include new territories,
- Acts of Parliament to extend Indian laws, and
- Judicial validation of administrative and constitutional changes.
📜 Constitutional Basis for Merging Territories
India’s Constitution provides clear mechanisms to admit, reorganize, or merge territories.
🔹 Article 1
Declares India as a “Union of States” and recognizes that new territories may be acquired and integrated.
🔹 Article 2
Empowers Parliament to admit or establish new States or territories into the Union on terms it deems fit.
🔹 Article 3
Allows Parliament to form new states, alter boundaries, or merge territories, with the President’s recommendation and consultation with the concerned State Legislature.
🔹 Article 4
Provides that laws made under Articles 2 and 3 will automatically amend the First Schedule (States & UTs list) and Fourth Schedule (Rajya Sabha representation) without needing a separate constitutional amendment.
Together, these Articles form the legal backbone for India’s territorial integration.
⚙️ The Legal Process of Merging Territories
The merger of a territory into India is not just symbolic — it involves a series of legal and administrative steps to ensure smooth governance.
Here’s how it unfolds:
1️⃣ Political Agreement or Accession
The process begins with a Treaty of Accession, Merger Agreement, or international treaty — depending on how the territory is acquired (for example, princely state accession or diplomatic cession).
2️⃣ Constitutional Recognition
Parliament amends the First Schedule to include the new territory and classifies it as a State or Union Territory.
3️⃣ Extension of Indian Laws
Special Acts, such as the Acquired Territories (Merger) Act, 1960, are passed to extend Indian laws — criminal, civil, taxation, and administrative — to the new territory.
4️⃣ Repeal of Old Laws
Existing colonial, princely, or foreign legal codes are gradually repealed to avoid conflict with Indian statutes.
5️⃣ Judicial and Administrative Integration
Courts, police, and administrative bodies are reorganized under Indian systems, ensuring citizens have access to Indian judiciary and governance.
🧾 Key Legal Instruments Governing Territorial Mergers
Several important laws and amendments facilitated this legal unification:
| Law / Amendment | Purpose | Key Effect |
|---|---|---|
| The Constitution (Ninth Amendment) Act, 1960 | Implemented the Indo-Pakistan Boundary Agreement | Adjusted Indian territory and borders legally |
| The Acquired Territories (Merger) Act, 1960 | Extended Indian laws to newly merged territories | Ensured uniform legal system |
| The Goa, Daman and Diu Administration Act, 1962 | Governed these Portuguese-acquired territories | Created Union Territories under Indian law |
| The Pondicherry (Administration) Act, 1962 | Integrated French territories into India | Established the UT of Puducherry |
| The Constitution (36th Amendment) Act, 1975 | Merged Sikkim as the 22nd State of India | Extended full constitutional rights to its citizens |
🧭 Major Legal Implications of Territorial Mergers
Now let’s understand what legally happens when a new territory becomes part of India.
⚖️ 1. Extension of the Indian Constitution
The first and most crucial step is the application of the Constitution of India to the merged area.
This ensures:
- Fundamental Rights under Part III apply to all residents,
- Directive Principles of State Policy guide governance, and
- The judicial structure becomes subject to High Courts and the Supreme Court.
Example: When Pondicherry merged, Indian citizenship and fundamental rights were extended to all its residents, replacing French constitutional protections.
📚 2. Repeal and Replacement of Existing Laws
Merged territories often had their own legal systems — French civil laws in Pondicherry, Portuguese codes in Goa, or princely regulations in Hyderabad.
Indian Parliament gradually repealed such laws to prevent contradictions. For instance:
- The Indian Penal Code (IPC) replaced older criminal codes.
- The Indian Evidence Act and Civil Procedure Code replaced colonial-era systems.
However, in some cases, local laws were retained temporarily to respect social and cultural practices — showing India’s flexibility in legal integration.
👥 3. Citizenship and Rights
Under the Citizenship Act, 1955, residents of merged territories automatically became citizens of India.
This had major legal implications:
- They gained the right to vote,
- Access to Indian courts, and
- Protection under Indian labor, property, and contract laws.
💰 4. Fiscal and Taxation Alignment
Newly merged territories needed alignment with India’s financial and tax systems.
The Income Tax Act, Customs Act, and Excise laws were extended to these regions, while previous revenue systems were abolished.
Example: After the merger of Goa, Daman, and Diu, the Indian taxation regime replaced Portuguese tax codes, ensuring fiscal parity with the rest of India.
⚖️ 5. Judicial Jurisdiction and Access to Justice
Each newly merged territory came under the jurisdiction of an appropriate High Court and the Supreme Court of India.
For instance:
- The Madras High Court initially had jurisdiction over Pondicherry.
- The Bombay High Court handled cases from Goa and Daman & Diu.
This integration ensured uniform justice delivery under India’s rule of law framework.
🌐 6. International and Diplomatic Obligations
When mergers involved foreign territories (like French or Portuguese colonies), India had to ensure compliance with international treaties and succession principles.
India assumed all legal obligations and liabilities of the predecessor administrations in these areas — in line with international law.
🧩 Real-Life Case Studies
🧿 Case Study 1: State of Saurashtra vs. Menon (1952)
After the princely states merged into India, disputes arose over the applicability of old state laws.
The Supreme Court held that Indian laws prevail once the territory becomes part of the Union, and that Parliament has the power to override previous systems.
🏖️ Case Study 2: Goa, Daman & Diu vs. Union of India (1963)
After the Portuguese territories were liberated in 1961, a challenge was made questioning India’s sovereignty and legal jurisdiction.
The Supreme Court upheld India’s authority, declaring that once Parliament includes a territory in the First Schedule, it becomes an integral part of India, and Indian laws apply automatically.
🕊️ Case Study 3: Union of India vs. Sikkim (1976)
Post-Sikkim’s merger, disputes arose over taxation and administrative laws.
The Court ruled that transitional provisions could continue temporarily, but ultimately all Indian constitutional laws would apply uniformly to Sikkim.
📊 Broader Legal and Social Impact

🌈 India’s Integration: A Legal Model of Unity
India’s approach to territorial integration is globally unique — it relied not on conquest, but on constitutional law, negotiation, and democratic consent.
By merging territories through legal frameworks, India ensured that every new region entered the Union as an equal partner, governed by the same Constitution and protected by the same rights.
It’s a shining example of how law can unite where politics divides.
