In this context, Dr. B.R. Ambedkar observed in the Constituent Assembly that: ‘All federal systems including American are placed in a tight mould of federalism. No matter what the circumstances, it cannot change its form and shape. It can never be unitary. On the other hand, the Constitution of India can be both unitary as well as federal according to the requirements of time and circumstances. In normal times, it is framed to work as a federal system. But in times of Emergency, it is so designed as to make it work as though it was a unitary system.’
