My book has explained the phrase "demand for grant" in the chapter "Indian Parliament" but i do not understand what do "demand" and "grant" mean. I tried googling them but did not find any valuable resource. What do they mean?
A Demand for Grant is a bill (i.e. piece of proposed legislation) seeking approval for estimated expenditures for a particular department or sub-department of a large department of the national or state or territory government from the national government's general fund, each of which must be approved separately by the Lok Sabha in order to authorize that spending pursuant to Article 113 of the Constitution.
"Revenue expenditures" (which are tax breaks that would be called "tax expenditures" in U.S. public policy parlance), "capital expenditures", intergovernmental grants, loans and advances against already approved expenditures for future time periods, must have a Demand for Grant approved as well.
In this context the word "Demand" means a formal request, and "grant" means a dispersement of money by a government or charity that is not legally obligated to disperse the money in any particular amount. So, a "demand for grant" is a formal request that money be voluntarily dispersed by the government as part of its annual discretionary general fund budget.
