This fact is not new to this House, as is evident from the Report of the Union Powers Committee, in paragraph 2 of their report dated 17th April 1947, where they say: Some of the above taxes are now regulated by agreement between the Government of India and the States. We therefore think that it may not be possible to impose a uniform standard of taxation throughout the Union all at once. We therefore recommend that uniformity of taxation throughout the Union may, for an agreed period of years after the establishment of the Union, not extending 15, be kept in abeyance and the incidence, levy and realisation and apportionment of the above taxes in the State units shall be subject to agreement between them and the Union Government. Provision should accordingly be made in the Constitution for implementing the above recommendation.
