These PILs challenged the allocation of coal blocks by the Central Government during 1993-2010. The allocation was done through a Screening Committee route and government dispensation route, without competitive bidding. Coal mining was nationalized in 1973, with private participation permitted only for captive use from 1993 onwards under the Coal Mines (Nationalisation) Act. The Central Government allocated coal blocks to private companies and state PSUs through an administrative process. Petitioners alleged the allocations were illegal, arbitrary, non-transparent, and made without following mandatory procedures under the Mines and Minerals (Development and Regulation) Act, 1957 and the CMN Act. They contended that the allocations resulted in windfall gains to allottees and huge losses to the public exchequer. The Central Government justified the allocations on the basis of power shortages, need to encourage private investment, and its purported authority under Sections 1A and 3(3) of the CMN Act.
