Who worked as a Constitutional Advisor for the Constituent Assembly of India?

Correct answer: B. N. Rau (Beni Madhab Rau) served as the Constitutional Advisor to the Constituent Assembly of India. He was appointed in 1946. Rau prepared the initial draft of the Constitution and carried out comparative studies of other countries' constitutions. His draft formed the basis for the work of the Drafting Committee. Dr. B. R. Ambedkar chaired the Drafting Committee that finalized the Constitution and is rightly credited for shaping the final text, but he was not the Constituent Assembly's Constitutional Advisor. K. M. Munshi served as a member of the Drafting Committee and contributed to the drafting process. Sachchidanand Sinha presided over the Assembly's first meeting as the temporary presiding officer (pro tem President); he did not serve as Constitutional Advisor. Why this distinction matters: the Constitutional Advisor produced the initial legal draft and guidance, while the Drafting Committee, under its chair, finalized and adopted the Constitution. Appointment year: 1946.
