Dr. B.R. Ambedkar observed that: “The dual polity which is inherent in a federal system is followed in all federations by a dual service. In all federations, there is a Federal Civil Service and a State Civil Service. The Indian federation, though a dual polity, will have a dual service, but with one exception. It is recognised that in every country there are certain posts in its administrative set up which might be called strategic from the point of view of maintaining the standard of administration. There can be no doubt that the standard of administration depends upon the calibre of the civil servants who are appointed to the strategic posts. The Constitution provides that without depriving the states of their rights to form their own civil services, there shall be an all-India service, recruited on an all-India basis with common qualifications, with uniform scale of pay and members of which alone could be appointed to those strategic posts throughout the Union”.
