The Supreme Court today sought several clarifications from the Centre relating to the policy and guidelines adopted in coal block allocations which was extended to private sector in the post-liberalisation era.

A division bench asked Attorney General G E Vahanvati to prepare the compilation of reports of all the screening committee meetings from 14th July 1993 to 31st March 2011 and the guidelines which were followed in the coal block allocations.

The court, which wants to know whether any policy was in place for the purpose of coal block allocation, said minutes of each meeting of screening committee will make things clear about each allocation.
