During the recess, the Departmentally Related Standing Committees of Parliament examine the Demand for Grants submitted by various Ministries.  The Demand for Grants are detailed explanations of that Ministry's annual budget which form part of the total budget of the government.  These are examined in detail, and the committees can approve of the demands, or suggest changes.  The Demand for Grants are finally discussed and voted on by the Parliament after the recess.  (The post below lists the ministries whose Demand for Grants will be discussed in detail after the recess). The issue is - how effective is the institution of Parliament in examining the budget?  Though India specific information on this subject is hard to find, K. Barraclough and B. Dorotinsky have cited the World Bank - OECD Budget procedures Database to formulate a table on the legislature approving the budget presented by the executive ("The Role of the Legislature in the Budget Process: A Comparative Review", Legislative Oversight and Budgeting).  I reproduce the table below:

In Practice, does the legislature generally approve the budget as presented by the Executive? (in percent)
Answer All Countries OECD Countries Presidential democracies Parliamentary democracies
It generally approves the budget with no changes 34 33 14 41
Minor changes are made (affecting less than 3% of total spending) 63 67 71 59
Major changes are made (affecting more than 3% but less than 20% of total spending) 2 0 7 0
The budget approved is significantly different (affecting more than 20% of total spending) 0 0 0 0

The Uttar Pradesh Legislative Assembly recently passed a resolution calling for the division of Uttar Pradesh [U.P] into four States. But the procedure for formation of new States laid down in Article 3 of the Constitution provides that a State has no say over the formation of new States beyond communicating its views to Parliament. Article 3 assigns to Parliament the power to enact legislation for the formation of new States. Parliament may create new States in a number of ways, namely by (i) separating territory from any State, (ii) uniting two or more States, (iii) uniting parts of States and (iv) uniting any territory to a part of any State. Parliament’s power under Article 3 extends to increasing or diminishing the area of any State and altering the boundaries or name of any State. Two checks constrain Parliament’s power to enact legislation for the formation of new States. Firstly, a bill calling for formation of new States may be introduced in either House of Parliament only on the recommendation of the President. Secondly, such a bill must be referred by the President to the concerned State Legislature for expressing its views to Parliament if it contains provisions which affect the areas, boundaries or name of that State. As can be seen, the only role that the U.P. State Legislature [the Legislative Assembly and Legislative Council] will play in any future formation of new States is when the President calls for its views to be placed before Parliament. Parliament will not be bound by these views in the process of enacting legislation for the formation of new States.
