Indian Constitution — Historical Underpinnings, Evolution & Basic Structure

Historical Background

The Indian Constitution was adopted on 26 November 1949 and came into effect on 26 January 1950. It is the longest written constitution in the world.

Constituent Assembly

• Formed under the Cabinet Mission Plan (1946)
• 389 members (reduced to 299 after Partition)
• Dr. Rajendra Prasad — President of the Constituent Assembly
• Dr. B.R. Ambedkar — Chairman of the Drafting Committee
• First meeting: 9 December 1946
• Total sessions: 11 over 2 years, 11 months and 18 days

Sources of the Constitution

Key Features

1. Longest Written Constitution — 395 Articles, 22 Parts, 8 Schedules (originally); now 470+ Articles, 25 Parts, 12 Schedules
2. Blend of Rigidity and Flexibility — Article 368
3. Federal with Unitary Bias — strong Centre, single citizenship, integrated judiciary
4. Parliamentary System — Executive responsible to Legislature
5. Independent Judiciary — Judicial review (Articles 13, 32, 226)
6. Fundamental Rights (Part III) — justiciable, enforceable by courts
7. Directive Principles (Part IV) — non-justiciable, guide policy
8. Secular State — 42nd Amendment added "secular" to Preamble
9. Universal Adult Franchise — every citizen 18+ can vote (61st Amendment, 1989)
10. Single Citizenship

Common Mistake: The Constitution does not define "basic structure" anywhere. There is no article that lists its elements. The doctrine was entirely a judicial creation in Kesavananda Bharati (1973), and its contours are still evolving through subsequent judgments. UPSC tested this directly in CSE 2020 — both statements were wrong because aspirants assumed basic structure is codified.

Basic Structure Doctrine

Established in Kesavananda Bharati v. State of Kerala (1973) — the Supreme Court held that Parliament can amend any part of the Constitution but cannot alter its "basic structure."

Elements of Basic Structure (from various judgments):

• Supremacy of the Constitution
• Sovereign, democratic, republican form of government
• Secular character
• Separation of powers
• Federal character
• Unity and integrity of the nation
• Judicial review
• Rule of law
• Free and fair elections

Key distinction: India's amendment procedure (Article 368) has three categories: (1) Simple majority — like an ordinary law (e.g., creation of new states), (2) Special majority — majority of total membership + 2/3rd present and voting (most amendments), (3) Special majority + ratification by half the state legislatures (federal provisions like election of President, distribution of powers). Knowing which category an amendment falls into is critical for Prelims.

Landmark Amendments

12 Schedules of the Constitution

Mnemonic: Remember the 12 Schedules sequence as: "States Salaries Oaths Rajya Tribes Tribes-NE Lists Languages Laws Defection Panchayat Municipality" — or the short form "SS-OR-TT-LL-DPM".

Seventh Schedule: Distribution of Legislative Powers (Article 246)

Key distinction: The 42nd Amendment (1976) transferred 5 subjects from State List to Concurrent List — education, forests, weights & measures, protection of wild animals & birds, and administration of justice. This is a classic Prelims question. Remember: "EFWPA" — Education, Forests, Weights, Protection of wildlife, Administration of justice.

Residuary Powers (Article 248)

Parliament has exclusive power to legislate on subjects not in any of the three lists. This is unlike the USA (where residuary powers lie with states) and similar to Canada.

Centre-State Relations

Legislative Relations (Articles 245–255)

• Parliament can legislate on State List subjects in 5 situations:
  1. During National Emergency (Article 250)
  2. On Rajya Sabha resolution by 2/3rd majority that it is in national interest (Article 249) — valid for 1 year, renewable
  3. When two or more states request Parliament to legislate on their behalf (Article 252)
  4. To implement international treaties (Article 253)
  5. During President's Rule in a state (Article 357)

Administrative Relations (Articles 256–263)

Financial Relations (Articles 268–293)

Key Commissions on Centre-State Relations

Sarkaria Commission (1983–1988)

Key Recommendations:

Punchhi Commission (2007–2010)

Key Recommendations:

Sarkaria vs Punchhi — Key Differences

UPSC Relevance: Sarkaria and Punchhi Commissions are directly tested in Prelims (number of recommendations, key proposals) and Mains (Centre-State reform debates). The key difference to remember: Sarkaria was conservative (status quo), Punchhi was reformist (structural changes). Neither commission's recommendations have been fully implemented.

Inter-State Council (Article 263)

Recent Federalism Debates

One Nation One Election

Governor Controversies — SC Rulings (2025)

Warning: The Governor controversy is a live, evolving issue. The November 2025 Presidential Reference overruled the April 2025 judgment — so be careful citing the "timelines for Governors" in answers. The current legal position is that no judicial timelines can be imposed on the Governor/President for acting on Bills.

GST Council as Cooperative Federalism

Cooperative vs Competitive Federalism

NITI Aayog's Role

NITI Aayog (constituted 1 January 2015) replaced the Planning Commission to actualise cooperative federalism — it does not impose centrally designed plans but enables states to adapt policies autonomously.

Important for UPSC

Prelims Focus

• 12 Schedules — what each contains, which amendment added 9th/10th/11th/12th
• Seventh Schedule — number of subjects in each list (100/61/52), subjects transferred by 42nd Amendment
• Basic Structure elements — not codified, judicial creation
• Amendment categories — simple majority vs special majority vs special + state ratification
• Constituent Assembly facts — 389→299 members, first meeting 9 Dec 1946, Drafting Committee 7 members
• Residuary powers with Parliament (not states — unlike USA)
• Sarkaria Commission: 1983, 247 recommendations; Punchhi Commission: 2007, 273 recommendations
• Inter-State Council: Article 263, established 1990, only 11 meetings
• GST Council: Article 279A, 3/4 majority, recommendations not binding (Mohit Minerals, 2022)
• One Nation One Election: Kovind Committee, 129th Amendment Bill (Dec 2024)

Mains Dimensions

• Cooperative vs Competitive Federalism — GST Council as model; NITI Aayog rankings; Aspirational Districts Programme
• Basic Structure — judicial overreach or safeguard? Compare with UK (Parliamentary sovereignty) and USA (constitutional amendments unchecked)
• Centre-State tensions — Governor's role, Article 356 misuse, fiscal autonomy, One Nation One Election implications
• 42nd vs 44th Amendment — Indira Gandhi's centralisation vs Morarji Desai's corrective; analyse which provisions survived
• Sarkaria vs Punchhi — Compare approaches to Governor's role and Article 356; evaluate why recommendations remain unimplemented
• Governor controversies — The 2025 SC rulings on Bills; balance between federalism and executive authority

Recent Developments (2024–2026)

Article 370 Abrogation Upheld — Asymmetric Federalism Question Resolved (December 2023)

The Supreme Court's unanimous five-judge ruling on 11 December 2023 (In Re: Article 370) upheld the abrogation of J&K's special status. The Court held that Article 370 was a temporary provision for facilitating J&K's integration into the Indian Union — not a permanent grant of quasi-sovereignty. The judgment explicitly confirmed that the Constitution's federal arrangement does not include internal sovereignty for any unit.

This ruling is foundational to understanding the Constitution's Basic Structure and its federal architecture: asymmetric federalism (differential status for specific states) is permissible as a transitional measure but cannot be permanent or sovereign in character.

UPSC angle: Prelims — In Re: Article 370 (11 December 2023); five-judge unanimous; temporary provision; no internal sovereignty. Mains — how does the Article 370 judgment reshape the debate on asymmetric federalism in India? Compare J&K's post-2019 constitutional status with Sixth Schedule states.

West Bengal v. Union of India — Article 131 and Federalism (2024)

The Supreme Court in 2024 upheld the maintainability of West Bengal's Article 131 suit against the Union, challenging continued CBI investigations in the state after West Bengal had withdrawn general consent. The Court affirmed that Article 131 can be invoked by states to protect their federal rights against Union overreach, reinforcing the constitutional principle that no level of government can override another's lawfully established jurisdiction.

The case is a direct application of the Basic Structure element of federalism — states have constitutional rights that can be adjudicated only by the Supreme Court in its original jurisdiction.

UPSC angle: Prelims — Article 131 (SC's original jurisdiction in Centre–State/inter-state disputes); West Bengal v. Union (2024); CBI general consent withdrawal. Mains — analyse how Article 131 serves as a constitutional safeguard for federal rights; evaluate the CBI's investigative jurisdiction in non-consenting states.

Nine-Judge Bench — States' Mineral Tax Power Strengthens Fiscal Federalism (July 2024)

In Mineral Area Development Authority v. SAIL (25 July 2024), a nine-judge bench (8:1) reaffirmed states' taxing power over minerals under Entry 50 of State List VII, overruling India Cements v. Tamil Nadu (1989). The ruling significantly strengthens fiscal federalism by allowing mineral-rich states (Jharkhand, Odisha, Chhattisgarh, Rajasthan) to collect additional state taxes on mining activities, which will substantially augment their own tax revenues.

UPSC angle: Prelims — MADA v. SAIL (2024); nine-judge bench; 8:1; states can tax minerals; Entry 50 State List. Mains — how does the MADA v. SAIL ruling affect the fiscal federal balance between Union and States? Connect to the 16th Finance Commission's mandate.

16th Finance Commission Constituted and Report Submitted (2024–2025)

The 16th Finance Commission was constituted with Dr. Arvind Panagariya (former NITI Aayog Vice Chairman and Columbia University economist) as Chairman. The Commission's terms of reference included determining tax devolution for 2026-31, recommending principles for grants-in-aid, and addressing GST compensation cess transition issues. The 16th Finance Commission submitted its report to President Droupadi Murmu on 17 November 2025 — ahead of schedule — covering the period 2026-27 to 2030-31.

Southern states (Tamil Nadu, Kerala, Karnataka, Andhra Pradesh, Telangana) have argued for higher devolution ratios (from 41% to 45–50%) and inclusion of cess and surcharges in the divisible pool, citing demographic management efforts penalised by population-based criteria.

UPSC angle: Prelims — 16th Finance Commission; Dr. Arvind Panagariya; report submitted November 2025; covers 2026-27 to 2030-31. Mains — evaluate the disputes between states and the Centre over fiscal devolution; how should the 16th FC address the north-south horizontal devolution debate?

Vocabulary

Constituent Assembly

• Pronunciation: /kənˌstɪtʃuənt əˈsɛmbli/
• Definition: A body of elected representatives empowered to draft or adopt a constitution for a country.
• Origin: From Latin constituere ("to set up, establish") + Old French assemblee ("a gathering"), from assembler ("to bring together").

Dominion

• Pronunciation: /dəˈmɪnjən/
• Definition: A self-governing territory within the British Empire that acknowledged the Crown as head of state while exercising internal sovereignty.
• Origin: From Middle English dominion, via Old French from Latin dominium ("lordship, right of ownership"), from dominus ("lord"), from domus ("house").

Sovereignty

• Pronunciation: /ˈsɒvrənti/
• Definition: The supreme and independent authority of a state to govern itself without external interference.
• Origin: From late Middle English, via Old French sovereinete, from soverain, based on Latin super ("above").

Key Terms

Cabinet Mission Plan

• Pronunciation: /ˈkæbɪnɪt ˈmɪʃən plæn/
• Definition: A 1946 British proposal by three Cabinet ministers — Lord Pethick-Lawrence (Secretary of State for India), Sir Stafford Cripps (President of the Board of Trade), and A.V. Alexander (First Lord of the Admiralty) — that rejected the demand for a separate Pakistan, recommended a three-tier federal structure for undivided India (Union at the top, Groups of Provinces in the middle, individual Provinces at the bottom), and laid the framework for the formation of the Constituent Assembly with 389 members (292 from provincial assemblies, 4 from chief commissioner's provinces, and 93 from princely states).
• Context: The three-member delegation arrived in New Delhi on 24 March 1946 to negotiate the transfer of power from British to Indian hands. Their plan proposed three groups: Group A (Hindu-majority provinces — Madras, Bombay, UP, Bihar, CP, Orissa), Group B (Muslim-majority provinces of northwest — Punjab, NWFP, Sindh, Baluchistan), and Group C (Bengal and Assam). Both the Indian National Congress and the Muslim League initially accepted the plan (June 1946), but disagreements over the compulsory vs voluntary nature of provincial grouping led to its collapse. Jawaharlal Nehru's press conference statement (10 July 1946) that the Congress was free to modify the plan within the Constituent Assembly prompted the Muslim League to withdraw its acceptance and call for "Direct Action Day" (16 August 1946), ultimately leading to Partition. Despite its failure as a unity plan, the Cabinet Mission's framework for the Constituent Assembly endured — the Assembly was constituted under this plan's provisions and began work on 9 December 1946.
• UPSC Relevance: GS2 Polity — Prelims: three members and their portfolios (Pethick-Lawrence, Cripps, Alexander), year (1946), arrival date (24 March 1946), three-tier structure proposed (Union-Groups-Provinces), rejected separate Pakistan demand, Constituent Assembly of 389 members formed under this plan; Mains: role of the Cabinet Mission in shaping India's federal structure, why the plan failed (grouping controversy — compulsory vs voluntary grouping, Nehru's 10 July 1946 statement), its legacy in the Constitution's federal design, comparison with the earlier Cripps Mission (1942) and the Mountbatten Plan (1947).

Objectives Resolution

• Pronunciation: /əbˈdʒɛktɪvz ˌrɛzəˈluːʃən/
• Definition: A historic resolution moved by Jawaharlal Nehru on 13 December 1946 and adopted unanimously by the Constituent Assembly on 22 January 1947 (with all members standing), laying down the guiding principles and aspirations — including sovereignty, justice, liberty, equality, and fraternity — that formed the philosophical foundation and blueprint for the Indian Constitution's Preamble. It declared India's resolve to constitute itself into a "Sovereign Independent Republic" and to secure justice, equality, and freedom for all citizens, with adequate safeguards for minorities, backward and tribal areas, and depressed classes.
• Context: After Nehru introduced the Resolution on 13 December 1946, it was debated extensively over several days (16-19 December 1946), then deferred and resumed on 21 January 1947, before being adopted unanimously on 22 January 1947. Key differences between the Objectives Resolution and the final Preamble: (1) the Resolution used "Sovereign Independent Republic" — the word "Independent" was dropped from the Preamble as redundant (sovereignty implies independence); (2) the Resolution explicitly mentioned safeguards for minorities, backward classes, and tribal areas — these found expression in Fundamental Rights (Articles 29-30) and DPSPs (Article 46) rather than the Preamble text; (3) the words "Socialist," "Secular," and "Integrity" were not in the Resolution or the original Preamble — they were added only by the 42nd Amendment (1976). The Preamble was the last item debated by the Constituent Assembly (17 October 1949) — after all other articles had been finalised — and was adopted as part of the Constitution on 26 November 1949.
• UPSC Relevance: GS2 Polity — Prelims: who moved it (Nehru), dates (moved 13 December 1946, adopted 22 January 1947), relationship to the Preamble, difference between Resolution text and final Preamble ("Independent" dropped, minority safeguards moved to Parts III and IV), the Preamble was debated last (17 October 1949); Mains: how the Objectives Resolution shaped the Constitution's philosophical framework, the transition from Resolution to Preamble — what was retained, modified, or dropped and why, significance of the Resolution as a "declaration of intent" that guided the entire constitution-making process over nearly three years.
