Origins of the Constituent Assembly Idea

M.N. Roy (December 1934)

Manabendra Nath Roy, communist intellectual, was the first to formally propose a Constituent Assembly for India in December 1934. Roy had been imprisoned 1932-36; his article "What Do We Want?" in 1934 articulated the demand.

Congress Adoption (1935 onwards)

The Indian National Congress took up the demand:

  • 1935 — Congress demanded a Constituent Assembly elected on the basis of adult franchise.
  • 1936 — Faizpur Congress reaffirmed the demand.
  • 1940 — Congress (Ramgarh, Subhash Bose's last as President in 1939, then Prasad) repeated demand.
  • 1940 — British August Offer by Linlithgow accepted the principle of a post-war Constituent Assembly.
  • 1942Cripps Mission proposed an Indian-elected Constituent Assembly to draft the post-war Dominion's constitution.
  • 1946 — Cabinet Mission Plan finally provided a workable framework.

Composition of the Constituent Assembly

Cabinet Mission Plan (May 1946)

The Cabinet Mission Plan (16 May 1946) outlined a Constituent Assembly of 389 members:

  • 292 from British Indian Provinces (population basis, 1 per million).
  • 4 from Chief Commissioners' Provinces (Delhi, Ajmer-Merwara, Coorg, British Baluchistan).
  • 93 from Princely States (negotiated through their representatives).

Election (July 1946)

Provincial members were elected by Provincial Legislative Assemblies — themselves elected on the limited GoI Act 1935 franchise (about 30% of adults). Voting was by single transferable vote within each Legislative Assembly. Three communal categories — General, Muslim, Sikh — voted separately.

Election Results (July 1946)

  • Indian National Congress — 208 seats.
  • Muslim League — 73 seats.
  • Independents — 15 seats.
  • Total: 296 (out of 296 elected from British Provinces; 93 princely states' members joined later).

After Partition (August 1947)

After the 3 June Plan (1947), the Assembly was divided:

  • India's Constituent Assembly: 299 members (after partition reductions and princely state inclusions).
  • Pakistan's Constituent Assembly: separately constituted at Karachi.

Notable Members

  • Pandit Jawaharlal Nehru
  • Dr Rajendra Prasad (President of CA)
  • Sardar Vallabhbhai Patel
  • Maulana Abul Kalam Azad
  • Dr B.R. Ambedkar — initially elected from Bengal; after Bengal's partition, re-elected from Bombay (with Congress support arranged by Patel and Gandhi).
  • K.M. Munshi
  • Alladi Krishnaswamy Ayyar
  • N. Gopalaswami Ayyangar
  • Mohammad Saadulla
  • Shyama Prasad Mookerjee
  • Dr H.C. Mukherjee (Vice-President of CA)
  • Sir B.N. Rau — Constitutional Adviser (not member, but key drafter)
  • Sachidananda Sinha — temporary President at first session

Women Members (15 in total)

The Constituent Assembly included 15 women members:

  • Sarojini Naidu
  • Vijaya Lakshmi Pandit
  • Hansa Mehta — proposed inclusive language in fundamental rights
  • Rajkumari Amrit Kaur
  • Sucheta Kripalani
  • Renuka Ray
  • Begum Aizaz Rasul — only Muslim woman member
  • Kamla Chaudhri
  • Annie Mascarene
  • Ammu Swaminathan
  • Dakshayani Velayudhan — first Dalit woman
  • Durgabai Deshmukh
  • G. Durgabai
  • Leela Roy
  • Purnima Banerji
  • Malati Choudhury

(Lists vary slightly by source between 14-15.)

First Session of the Constituent Assembly (9 December 1946)

The Constituent Assembly first met on 9 December 1946 at 11 a.m. in the Constitution Hall (now Central Hall of Parliament) at Delhi.

Boycott by Muslim League

The Muslim League boycotted the first session — refusing to participate in the Constituent Assembly because (i) the Cabinet Mission Plan's ambiguity about grouping had been resolved against the League's interpretation; (ii) by November 1946, the League had decided to insist on Pakistan. Only 211 of the 296 elected members attended initially.

Sachidananda Sinha — Temporary Chairman

Dr Sachidananda Sinha (1871-1950), the oldest member, presided over the first session as temporary chairman — following the convention of French Constituent Assemblies. He was a Bihari lawyer-politician, founder of Hindustan Review (1899), and a long-time Liberal-moderate Congress figure. His inaugural address welcomed members and outlined the Assembly's task.

Permanent President: Dr Rajendra Prasad (11 December 1946)

On 11 December 1946, Dr Rajendra Prasad was elected permanent President of the Constituent Assembly — defeating Pattabhi Sitaramayya. Prasad presided over all subsequent sessions until 26 November 1949.

Dr H.C. Mukherjee was elected Vice-President.

Sir B.N. Rau (Benegal Narsing Rau) was appointed as the Constitutional Adviser — a former ICS officer with extensive experience drafting constitutions for Burma and others. He prepared the initial draft.

The Objective Resolution (13 December 1946)

On 13 December 1946, Pandit Jawaharlal Nehru moved the Objective Resolution — a comprehensive statement of the philosophical foundations of the new Indian state.

Key Provisions of the Objective Resolution

  1. India shall be an Independent Sovereign Republic.
  2. Constitution-making for British India provinces, princely states, and any other parts willing to join.
  3. Federal structure with autonomous units exercising residuary powers.
  4. Sovereignty derived from the people.
  5. All power and authority traceable to the people.
  6. Justice — social, economic, political; equality of status and opportunity; freedoms of thought, expression, belief, faith, worship, vocation, association.
  7. Adequate safeguards for minorities, backward and tribal areas, depressed and other backward classes.
  8. India's territorial integrity.
  9. India to participate in promoting world peace and welfare of mankind.

The resolution was adopted by the Assembly on 22 January 1947. Its language and sentiments are reflected in the Preamble of the Constitution.

⚠ EXAMINER TRAP — Objective Resolution date Moved by Nehru: 13 December 1946. Adopted: 22 January 1947. The Objective Resolution is the philosophical foundation of the Indian Constitution; its essence is reflected in the Preamble. Frequently tested.

Major Committees of the Constituent Assembly

The Constituent Assembly worked through over 22 committees (some sources say 13 major + 9 minor). The most important:

CommitteeChairman
Drafting CommitteeDr B.R. Ambedkar
Union Powers CommitteePandit Jawaharlal Nehru
Union Constitution CommitteePandit Jawaharlal Nehru
States Committee (negotiating with Princely States)Pandit Jawaharlal Nehru
Provincial Constitution CommitteeSardar Vallabhbhai Patel

Sub-Committee on North-East Frontier & Excluded AreasGopinath Bardoloi
Sub-Committee on Excluded & Partially Excluded Areas (other than NE)A.V. Thakkar
Sub-Committee on Hindi-Urdu (Language)Munshi

Key Patterns

  • Nehru chaired the powers, constitution, and states committees — the "macro" architecture.
  • Patel chaired the provincial, fundamental rights, minorities, and tribal committees — the "individual rights" architecture.
  • Rajendra Prasad handled procedure and steering.
  • Ambedkar headed the central drafting work.

The Drafting Committee (29 August 1947)

The Drafting Committee was constituted on 29 August 1947 — exactly two weeks after independence. It was tasked with producing the formal draft text on the basis of inputs from the various subject committees.

Composition (7 members)

  1. Dr B.R. Ambedkar — Chairman.
  2. Alladi Krishnaswamy Ayyar — eminent Madras lawyer.
  3. N. Gopalaswami Ayyangar — former Diwan of Kashmir, drafted Article 370.
  4. K.M. Munshi — lawyer-politician.
  5. Mohammad Saadulla — Muslim representative.
  6. B.L. Mitter — replaced after resignation by N. Madhava Rau.
  7. D.P. Khaitan — replaced after death by T.T. Krishnamachari.

Process

  • The Drafting Committee worked from August 1947 to November 1949.
  • Held 141 sessions.
  • Used Sir B.N. Rau's preliminary draft (October 1947) as the working basis.
  • Published the Draft Constitution in February 1948 for public comment.
  • Received over 7,635 amendments; about 2,473 were actually moved.
  • Ambedkar introduced the Draft Constitution on the floor of the Assembly on 4 November 1948 with a celebrated speech.
  • Three readings completed by 26 November 1949.

Ambedkar's Role

Dr B.R. Ambedkar (1891-1956) is rightly called the "Father of the Indian Constitution". As Chairman of the Drafting Committee, he was the principal draftsman. He had:

  • PhD from Columbia University, DSc from London School of Economics, Bar at Lincoln's Inn.
  • Decades of experience as a constitutional thinker — author of "States and Minorities" (1947).
  • Joined Nehru's Cabinet as Law Minister (15 August 1947).
  • Worked despite poor health — diabetic, with arthritis.

Granville Austin called Ambedkar "the chief architect"; T.T. Krishnamachari said: "the bulk of the work has been done by Dr Ambedkar." Ambedkar is celebrated annually on 14 April (his birthday) and 6 December (Mahaparinirvana Diwas, his death anniversary).

Sir B.N. Rau (Constitutional Adviser)

Sir Benegal Narsing Rau (1887-1953) was the Constitutional Adviser — a former ICS officer who had drafted the Constitution of Burma (1947). He prepared the preliminary draft (October 1947) after extensive consultations with constitutional experts in the US, UK, Canada, Ireland. The Drafting Committee's work was based on Rau's draft. He was not a member of the Constituent Assembly. Rau later became a judge of the International Court of Justice (1952).

Sources of the Indian Constitution

The Indian Constitution drew from many sources, both indigenous and foreign:

SourceProvisions Adopted
Government of India Act 1935Federal structure; office of Governor; emergency provisions; Public Service Commission; administrative provisions (~250 articles per Granville Austin)
British ConstitutionParliamentary form; rule of law; legislative procedure; single citizenship; cabinet system; prerogative writs; bicameral legislature
US ConstitutionFundamental Rights; independent judiciary; judicial review; impeachment of President; removal of Supreme Court & HC judges; office of Vice-President
Irish ConstitutionDirective Principles of State Policy; nominated members of Rajya Sabha; method of election of President
Canadian ConstitutionFederation with strong Centre; vesting of residuary powers in Centre; advisory jurisdiction of Supreme Court; appointment of state Governors by Centre
Australian ConstitutionConcurrent List; freedom of trade, commerce, intercourse; joint sitting of Parliament
Weimar Constitution (Germany)Suspension of Fundamental Rights during emergency
Soviet (USSR) ConstitutionFundamental Duties; ideal of social, economic, political justice in Preamble
French ConstitutionRepublic; ideals of liberty, equality, fraternity in Preamble
South African ConstitutionProcedure for amendment of the Constitution; election of Rajya Sabha members
Japanese Constitution"Procedure established by law" (Article 21)

The Indian Constitution is therefore eclectic — a "borrowed Constitution", in K. Hanumanthaiya's controversial phrase, but Ambedkar defended this as wise selection from the world's best practices.

Enactment of the Constitution

Adoption: 26 November 1949

The Constitution was adopted by the Constituent Assembly on 26 November 1949. This date is celebrated as "Constitution Day" / "Samvidhan Divas" (declared in 2015 by GoI).

On the day of adoption, Ambedkar moved that the Constitution as drafted be passed. After Rajendra Prasad's address, the Constitution was passed.

Signing (24 January 1950)

On 24 January 1950, the final session of the Constituent Assembly took place. The members signed the original Constitution — 284 members signed the original parchment in Hindi, English, and other languages. The same day:

  • "Jana Gana Mana" adopted as the National Anthem.
  • "Vande Mataram" (first two stanzas) adopted as the National Song.
  • Dr Rajendra Prasad elected first President of India (taking office on Republic Day).

Coming into Force: 26 January 1950

The Constitution came into force on 26 January 1950 — the date chosen to commemorate the Lahore Congress's Purna Swaraj Declaration of 26 January 1930. India became a sovereign democratic Republic.

FAQs

Who was Sachidananda Sinha?
Dr Sachidananda Sinha (1871-1950) was a Bihari lawyer-politician and editor. As the oldest member of the Constituent Assembly, he was elected temporary chairman for the inaugural session on 9 December 1946 — following French Constituent Assembly precedent. He was a long-time Liberal-Moderate Congress figure, founder of Hindustan Review (1899), former Member of the Imperial Legislative Council (1908) and Bihar Legislative Council. After 11 December 1946, Rajendra Prasad became permanent President. Sinha is also called the "Father of Bihar" for his decades of advocacy of Bihar's separation from Bengal (achieved 1912).
Why is 26 January Republic Day?
26 January was chosen as the date for the Constitution to come into force to commemorate the Lahore Congress's Declaration of Purna Swaraj on 26 January 1930 (the Indian Independence Day declared by the Congress under Jawaharlal Nehru's presidency at the Lahore session of December 1929). 26 January 1930 was the first "Independence Day" celebrated across India — well before actual independence on 15 August 1947. By choosing 26 January 1950 for the Constitution's commencement, India linked the Republic to the freedom movement's purna swaraj aspiration.
How many women were in the Constituent Assembly?
The Constituent Assembly had 15 women members (some sources say 14). The most prominent: Sarojini Naidu, Vijaya Lakshmi Pandit, Hansa Mehta, Rajkumari Amrit Kaur, Sucheta Kripalani, Renuka Ray, Begum Aizaz Rasul (only Muslim woman), Annie Mascarene, Ammu Swaminathan, Dakshayani Velayudhan (first Dalit woman), Durgabai Deshmukh, Kamla Chaudhri, Leela Roy, Purnima Banerji, Malati Choudhury. Despite their small numbers (about 5%), women made significant contributions — Hansa Mehta proposed inclusive language in fundamental rights, Sarojini Naidu and Vijaya Lakshmi Pandit took international roles, Durgabai Deshmukh chaired several committees.
Who calligraphed the Original Constitution?
The original Constitution of India was hand-written by Prem Behari Narain Raizada (1901-1986), a renowned calligrapher who refused payment for his work — only requesting that his name and his grandfather Master Ram Prasad's name appear on every page. The Hindi version was calligraphed by Vasant Krishan Vaidya. Both texts were illuminated and decorated by Nandalal Bose (1882-1966) and his Shantiniketan students — with each part beginning with an illustration of a phase of Indian history. The original is preserved in helium-filled chambers at the Parliament Library.
What did Ambedkar say while introducing the Draft Constitution?
In his speech of 4 November 1948 (introducing the Draft) and 25 November 1949 (concluding speech before adoption), Dr B.R. Ambedkar gave several memorable observations: (1) "The Constitution can provide only the organs of State... The factors on which the working of those organs depends are the people..."; (2) Warning of the danger of "Bhakti or hero worship" in politics; (3) Stressed the need to renounce "the bloody methods of revolution" in a democracy; (4) Pointed out India was entering a "life of contradictions" — political equality but social and economic inequality; (5) Famously: "I feel that the Constitution is workable; it is flexible and it is strong enough to hold the country together both in peacetime and in wartime." The speeches are studied as foundational documents of Indian constitutionalism.
How was the Constituent Assembly elected?
The Constituent Assembly members from British Indian Provinces were elected indirectly by the Provincial Legislative Assemblies in July 1946. Provincial Legislatures themselves had been elected on the limited GoI Act 1935 franchise (about 30% of adults). Voting in the Provincial Legislative Assemblies was by single transferable vote (proportional representation) within three communal categories — General, Muslim, Sikh. The members from Princely States were nominated through negotiation with their rulers. After Independence, the Assembly was sovereign and could effectively co-opt any necessary new members.
