Revenue Secretary Sunil Mitra while addressing a conference in New Delhi said that the committee will discuss threadbare the Constitutional Amendment Draft for GST. He said that the consensus of States has to be acceptable to Centre. Mr Mitra also outlined the issues of contention among the states.
