B. N. Rau and S. N. Mukherjee were two civil servants who assisted the Constituent Assembly in framing the Constitution of India.
Sir Benegal Narsing Rau (B. N. Rau) was appointed as the Constitutional Advisor to the Constituent Assembly. He prepared the initial draft of the Constitution in October 1947, taking into account reports of various committees and the Constitutions of other countries. S. N. Mukherjee was the Chief Draftsman of the Constitution. He played a crucial technical role in translating the decisions of the Assembly and the Drafting Committee into the final legal text of the Constitution with great precision and clarity.
K. M. Munshi and Alladi Krishnaswamy Aiyar were distinguished lawyer members of the Drafting Committee of the Constituent Assembly, not primarily civil servants assisting in the drafting process in the advisory or technical drafting roles held by Rau and Mukherjee. While crucial to the framing, they served as political members and legal experts within the committee structure.
