In the federal scheme for India, as outlined under the Act of 1935, the powers of the Centre and of the provinces were more or less exhaustively enumerated in three lists, the exclusively federal, the concurrent and the exclusively provincial ; further, the residuary power as such was neither with the Centre nor with the provinces, but was to be allotted (as and when each specific case arose) to the Centre or to the provinces by the Governor-General in his discretion.
