Almost every Polity paper in SSC, Railway and State exams has a question from this chapter. Who presided over the first sitting of the Constituent Assembly? When was the Constitution adopted, and why did it come into force only two months later? Which country gave us the Directive Principles? Learn this one chapter properly and you have marks that come back in paper after paper.
Where the idea came from
The demand that Indians should frame their own constitution grew out of the freedom movement. M.N. Roy was the first to put forward the idea of a Constituent Assembly, in 1934. The Indian National Congress made it an official demand in 1935, and the British government accepted the demand in principle in the August Offer of 1940. The Assembly was finally set up in 1946 under the Cabinet Mission Plan.
How the Assembly was formed
The Cabinet Mission Plan fixed the total strength of the Assembly at 389: 296 seats for British India and 93 for the princely states. Of the 296, 292 were for the eleven governors' provinces and 4 for the chief commissioners' provinces. Seats were shared out among the provinces broadly in proportion to their population.
The members were not elected directly by the people. The members of the provincial legislative assemblies elected them, using proportional representation by means of the single transferable vote. The representatives of the princely states were to be nominated by their rulers.
Elections to the 296 seats of British India were held in July and August 1946. The Congress won 208 seats, the Muslim League 73, and small groups and independents the remaining 15. After Partition, the members from the areas that went to Pakistan left the Assembly, and its strength came down to 299: 229 from the provinces and 70 from the princely states.
| Stage | British India (provinces) | Princely states | Total |
|---|---|---|---|
| Under the Cabinet Mission Plan, 1946 | 296 | 93 | 389 |
| After Partition, 1947 | 229 | 70 | 299 |
Remember: 389 at the start (296 + 93), 299 after Partition (229 + 70). The Assembly was indirectly elected and partly nominated, never directly elected by the people.
The Assembly at work: dates you must know
The Assembly met for the first time on 9 December 1946. The Muslim League stayed away and demanded a separate state of Pakistan. Dr Sachchidananda Sinha, the oldest member, was made the temporary President, following the French practice. Two days later, on 11 December 1946, Dr Rajendra Prasad was elected President of the Assembly, with H.C. Mukherjee and V.T. Krishnamachari as Vice-Presidents. Sir B.N. Rau was appointed its constitutional adviser.
| Date | What happened |
|---|---|
| 9 December 1946 | First meeting; Dr Sachchidananda Sinha temporary President |
| 11 December 1946 | Dr Rajendra Prasad elected President of the Assembly |
| 13 December 1946 | Jawaharlal Nehru moved the Objectives Resolution |
| 22 January 1947 | Objectives Resolution adopted |
| 22 July 1947 | National Flag adopted |
| 29 August 1947 | Drafting Committee set up under Dr B.R. Ambedkar |
| February 1948 | Draft Constitution published |
| 26 November 1949 | Constitution adopted (observed as Constitution Day) |
| 24 January 1950 | Last session; National Anthem and National Song adopted; Dr Rajendra Prasad elected first President of India |
| 26 January 1950 | Constitution came into force (Republic Day) |
The Objectives Resolution laid down the philosophy of the Constitution: India as an independent, sovereign republic, with justice, equality and freedom for all its people and safeguards for minorities and backward classes. Its ideas were later shaped into the Preamble.
The Assembly also had a second job. After independence it worked as the country's first Parliament, the Dominion Legislature. When it met as a legislature it was chaired by G.V. Mavalankar; when it met to frame the Constitution, Dr Rajendra Prasad presided.
Exam trap: 26 November 1949 is the day the Constitution was adopted; 26 January 1950 is the day it came into force. A few provisions, such as those on citizenship, elections, the provisional Parliament and temporary and transitional matters, took effect on 26 November 1949 itself. 26 January was chosen for the rest because the Congress had celebrated that day as Purna Swaraj Day in 1930.
The committees and their chairmen
The Assembly divided its work among a number of committees. Questions often give a committee and ask for its chairman, so learn them as pairs.
| Committee | Chairman |
|---|---|
| Union Powers Committee | Jawaharlal Nehru |
| Union Constitution Committee | Jawaharlal Nehru |
| States Committee (for negotiating with the princely states) | Jawaharlal Nehru |
| Provincial Constitution Committee | Sardar Vallabhbhai Patel |
| Advisory Committee on Fundamental Rights, Minorities and Tribal and Excluded Areas | Sardar Vallabhbhai Patel |
| Rules of Procedure Committee | Dr Rajendra Prasad |
| Steering Committee | Dr Rajendra Prasad |
| Ad hoc Committee on the National Flag | Dr Rajendra Prasad |
| Drafting Committee | Dr B.R. Ambedkar |
Two sub-committees of the Advisory Committee are also asked about: the Fundamental Rights Sub-Committee, chaired by J.B. Kripalani, and the Minorities Sub-Committee, chaired by H.C. Mukherjee.
Memory hook: Nehru took the Union and the States; Patel took the Provinces and the Rights; Prasad took the Rules, the Steering and the Flag; Ambedkar took the Draft.
The Drafting Committee
The most important of these, the Drafting Committee, was set up on 29 August 1947. It had seven members:
- Dr B.R. Ambedkar (Chairman)
- N. Gopalaswamy Ayyangar
- Alladi Krishnaswamy Ayyar
- Dr K.M. Munshi
- Syed Mohammad Saadullah
- N. Madhava Rau, who replaced B.L. Mitter when he resigned on grounds of health
- T.T. Krishnamachari, who replaced D.P. Khaitan after his death in 1948
The committee worked on the initial draft prepared by B.N. Rau and published its Draft Constitution in February 1948. The Assembly then went through the draft clause by clause, and more than two thousand proposed amendments were discussed on its floor. Ambedkar piloted the draft through the House, which is why he is remembered as the chief architect of the Constitution.
Time, sessions and the original document
The Assembly took 2 years, 11 months and 18 days to finish its work. In that time it held 11 sessions over 165 days, of which 114 days went into considering the draft. The total cost came to about ₹64 lakh.
As adopted in 1949, the Constitution had a Preamble, 395 Articles in 22 Parts and 8 Schedules. It has grown a great deal since then through amendments, so when a question says "originally", it means these numbers.
The original copies were written by hand, not printed. Prem Behari Narain Raizada wrote the English text in flowing italic calligraphy and Vasant Krishan Vaidya wrote the Hindi version, while artists of Shantiniketan led by Nandalal Bose decorated the pages. The elephant was the symbol (seal) of the Constituent Assembly.
Borrowed features: the sources of the Constitution
The framers studied the constitutions of many countries and adopted what suited Indian conditions, changing it where needed. The largest single source was the Government of India Act, 1935, and much of the structure of the Constitution comes from it.
| Source | Features taken |
|---|---|
| Government of India Act, 1935 | Federal scheme, office of Governor, judiciary, Public Service Commissions, emergency provisions and administrative details |
| Britain | Parliamentary government, rule of law, legislative procedure, single citizenship, cabinet system, prerogative writs, parliamentary privileges and bicameralism |
| United States | Fundamental Rights, independence of the judiciary, judicial review, impeachment of the President, removal of Supreme Court and High Court judges, and the post of Vice-President |
| Ireland | Directive Principles of State Policy, nomination of members to the Rajya Sabha and the method of election of the President |
| Canada | Federation with a strong Centre, residuary powers with the Centre, appointment of state Governors by the Centre and the advisory jurisdiction of the Supreme Court |
| Australia | Concurrent List, freedom of trade, commerce and intercourse, and the joint sitting of the two Houses of Parliament |
| Weimar Constitution of Germany | Suspension of Fundamental Rights during an Emergency |
| Former USSR | Fundamental Duties and the ideal of justice (social, economic and political) in the Preamble |
| France | Republic, and the ideals of liberty, equality and fraternity in the Preamble |
| South Africa | Procedure for amendment of the Constitution and election of members of the Rajya Sabha |
| Japan | Procedure established by law |
Memory hooks: Rights from the USA (its Bill of Rights), Directive Principles from Ireland, Duties from the USSR, the Concurrent List from Australia, emergency suspension of rights from Germany, and the amendment procedure from South Africa.
