In India, It's the Legislatures, Right?

In India, state legislatures usually have the power to tax. So if all state governments come together and say that in the spirit of a vertical redistribution,. 80 % should go to the state governments, and only 20% to the union government? That can't happen because of the structure - i understand wyte had be the case. But her, what is happening as you have created a body which has representation of different state governments; they are deciding it. There has been this kind of conflict from the beginning. And some state finance ministers have also pointed out that maybe it's sudden union government ministries or officials, they are the ones wearing deciding things.
