The dual polity which is inherent in a federal system as I said 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 recognized 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. It may not be easy to spot such posts in a large and complicated machinery of administration. But there can be no doubt that the standard of administration depends upon the calibre of the Civil Servants who are appointed to these strategic posts. Fortunately for us we have inherited from the past system of administration which is common to the whole of the country and we know what are these strategic posts. The Constitution provides that without depriving the States of their right 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 the members of which alone could be appointed to these strategic posts throughout the Union.
