The Constituent Assembly was constituted under the Cabinet Mission Plan of 1946 to draft a constitution for India that would replace the Government of India Act 1935.

BN Rau drafted the initial document
BN Rau, born on 26 February 1887, was a civil servant, jurist, diplomat, and statesman. He played a critical and primary role in the Indian constitution-making process as the constitutional advisor to the Constituent Assembly. Rau was responsible for the general structure of the democratic framework of the Constitution and single-handedly prepared its initial draft in February 1948. This draft was then debated, revised, and finally adopted by the Constituent Assembly of India on 26 November 1949. Rau's draft was based on extensive research, including consultations with judges, scholars, and authorities on constitutional law in the US, Canada, Ireland, and the United Kingdom.
Rau's contributions to the Indian Constitution were significant and wide-ranging. He had a deep understanding of Indian law and constitutional precedents, as evidenced by his noted writings on the subject. As an adviser to the Constituent Assembly, Rau played a crucial role in shaping the democratic framework of the Constitution. He was responsible for the initial draft, which laid the foundation for the final document. Rau's draft was the result of his legal expertise and his efforts to resolve the political deadlock between the Indian National Congress and the Muslim League, who had opposing visions for the constitutional future of India.
Rau's draft Constitution was a comprehensive document that outlined his proposed constitutional scheme. It consisted of analysis, explanatory notes, and memoranda written in a legal style with articles and clauses. This initial draft was then scrutinised and discussed by the Drafting Committee, which was chaired by Dr B. R. Ambedkar, who is often referred to as the "father of the Indian Constitution". The Drafting Committee included other legal experts and administrative luminaries such as KM Munshi, N Gopalaswamy Ayyangar, Alladi Krishnaswamy Ayyar, Syed Mohammad Saadullah, and N Madhava Rau.
The drafting process was a collaborative effort that involved multiple revisions and inputs from various experts. The first draft by the Drafting Committee was published in February 1948, and the people of India were given eight months to discuss and propose amendments. The feedback from the public was then incorporated into a second draft published in October 1948. After three drafts and three readings, the final constitution was passed on 26 November 1949.
While Dr B. R. Ambedkar is widely recognised as the chief architect of the Indian Constitution, it is important to acknowledge the significant contributions of BN Rau. As the constitutional advisor, Rau's expertise, research, and draft Constitution laid the groundwork for the final document. His role in the constitution-making process highlights his dedication to India's democratic ideals and his impact on the country's political landscape.
