In this capacity, he was responsible for preparing the initial draft of the Constitution, which he submitted in October 1947 [1]. This draft, containing 243 articles and 13 schedules, served as the foundational document for the Drafting Committee [1]. While Dr. B.R. Ambedkar served as the Chairman of the Drafting Committee [2], B.N. Rau provided the essential legal framework and research into comparative constitutional law that guided the committee's work. Other figures mentioned, such as Dr. Sachidananda Sinha, served as the provisional president of the Assembly [1], and B. Shiva Rao was a member of the Assembly but not the primary constitutional advisor. Rau's role was pivotal in synthesizing diverse legal perspectives into the cohesive initial document.
