The Constitution of India stands as the supreme law of the nation, crafted by the Constituent Assembly elected by the members of the Provincial Assemblies. 

Constituent Assembly 

• Established in December 1946, the Constituent Assembly dedicated the next three years to framing the most crucial document for a newly independent nation. 
• The Constitution of India holds the distinction of being the longest written constitution globally. 

Demands for Constituent Assembly 

• The call for a Constituent Assembly to formulate the Constitution first gained prominence in 1934 through MN Roy. In 1935, the Indian National Congress officially advocated for its establishment. 
• In 1938, Jawaharlal Nehru, representing the Indian National Congress (INC), asserted that the Constitution of Free India should be crafted without external interference by a Constituent Assembly elected based on adult franchise. 
• The British Government eventually proposed the creation of a representative body comprising Indians to draft a Constitution for India in the August Offer of 1940. 
• During the Cripps Mission, the British agreed to the establishment of a Constituent Assembly consisting entirely of Indians. However, the Muslim League rejected the Cripps Proposals as they aimed to divide India into two independent states with separate Constituent Assemblies. 

Formation of Constituent Assembly 

• A Cabinet Mission was ultimately dispatched to India, proposing a plan for the Constituent Assembly that was most agreeable to the Muslim League. It was established in November 1946 as per the Cabinet Mission Plan of 1946. 
• However, the elections to the assembly were conducted indirectly. In 1946, the British, contemplating the possibility of granting independence to India, sent a British Cabinet Mission to India to: 
  • Hold discussions with the representatives of British India and the Indian States to agree on the framework for drafting a constitution. 
  • Set up a constituent body and an executive council. 
  • The Assembly was to have proportional representation from existing provincial representation and various Princely States. The majority of these elections were completed by the end of July 1946, under the supervision of the reforms office under the Governor-General (Viceroy). 

The Constituent Assembly came into force in 1946, with members including Jawaharlal Nehru, Dr. Rajendra Prasad, Sardar Vallabhbhai Patel, Maulana Azad, and many other supreme leaders of the country. 

• Each Province and each Princely State or Group of States were allotted seats proportional to their respective populations. The provinces under direct British rule elected 292 members, while the Princely States were allotted a minimum of 93 seats, with an additional 4 seats for Chief Commissioner provinces. 
• The Assembly consisted of 389 members representing Provinces (292), States (93), the Chief Commissioner Provinces (3), and Baluchistan (1). 
• The strength of the Assembly was reduced to 299 following the withdrawal of the Muslim League members after the partition of the country. 
• The seats in each Province were distributed among the three main communities, Muslims, Sikhs, and General, in proportion to their respective populations. 
• Parties represented in the Constituent Assembly were the Congress Party, which had a majority, the Muslim League, Scheduled Caste representation, the Indian Communist Party, and the Union Party. 

Proceeding of the Constituent Assembly  

• Proceedings of the Constituent Assembly began as it met for the first time on 9th December 1946. 
• The Muslim League boycotted the Constituent Assembly owing to their continued demand for a separate state of Pakistan. 
• Thus, the strength of the assembly was reduced to 299. The meeting was attended by only 211 members. 

Dr. Sacchidananda Sinha was elected as the Interim President of the Assembly. On 11th December 1946, Dr. Rajendra Prasad was elected as the President and HC Mukherjee as the Vice-President of the Constituent Assembly. BN Rau was appointed as the Constitutional Advisor. 

Objective Resolution 

• On 13th December 1946, Pt. Jawaharlal Nehru moved the Objective Resolution, laying down the fundamentals and philosophy of the constitutional structure. 

Main Points of the Objective Resolution: 

• India is an independent sovereign republic. 
• India shall be a Union of erstwhile British India territories, Indian states, and other parts outside British India and Indian states willing to be a part of the Union. 
• Territories forming the Union shall be autonomous units and exercise all powers and functions of the government and administration, except those assigned to or vested in the Union. 
• All powers and authority of sovereign and independent India and its Constitution shall flow from the people. 
• All people of India shall be guaranteed and secured social, economic, and political justice; equality of status and opportunities; and equality before the law, along with fundamental freedoms of speech, expression, belief, faith, worship, vocation, association, and action subject to law and public morality. 
• Adequate safeguards will be ensured for minorities, backward and tribal areas, as well as the depressed and Other Backward Classes.
