During the Constituent Assembly debates, Dr. B. R. Ambedkar defended the inclusion of the provisions for the imposition of President’s Rule in states (Article 356). He expressed hope that these powers would be used sparingly and only as a ‘matter of last resort’ when constitutional machinery in a state had truly failed.
Article 356 allows the President to assume functions of the state government if the constitutional machinery in that state breaks down. Ambedkar envisioned it as a safeguard to uphold the constitution, not as a tool for political intervention.
Article 352 deals with National Emergency, Article 359 with suspension of fundamental rights during emergencies, and Article 368 with the power of Parliament to amend the Constitution. While important, Article 356 is the one specifically associated with Ambedkar’s “last resort” statement.
