It therefore had a dual role:
Framed the Constitution.
Performed legislative functions until the new Parliament was constituted.

The Constituent Assembly's journey from its first sitting in December 1946 to the commencement of the Constitution in January 1950 reflects a carefully sequenced process of deliberation, committee work, drafting, debate and constitutional adoption. The timeline demonstrates that India's Constitution was the outcome of nearly three years of sustained constitution-making rather than a single drafting exercise.
