That?s why the Planning Commission as well as finance commission follows certain formula while according special status to a state. The Gadgil formula used from 1969 to eve of sixth-plan, modified Gadgil formula from sixth plan to 1990, Gadgil-Mukherjee formula from 1990 to 2000 and finally Gadgil 2000 formula from 2000 onwards are the base for deciding special status (or rather special grant).
The danger of special grant (or status) being arbitrary is that, this may result in becoming a bargaining tool in future particularly in government making. As this is a coalition era, thus states having more MPs and particularly belonging to a regional party, then they would extend support in the government formation only on condition of special grant. This would be a continuous and never ending bargain, resulting in discrimination against the smaller states purely because of lack of number of MPs. This will give rise to severe disparity among states on growth and financial condition. This will also defeat the Constitutional mandate on federal structure that each state should get equal opportunity and equal growth.
That's why special status is always based on certain formula appropriate to the situation so that no injustice is done against any state. UPA government whimsically and arbitrarily declared the special status to Seemandhra not realizing the consequences. BJP too aiming electoral salvage couldn?t envisage the danger. Therefore the Central government urgently needs to withdraw the special status declaration and replace it with a special package.
