The Supreme Court of India in IndraSawhney vs. Union of India case (1992) had observed that there is no constitutional or legal bar on states for categorizing OBCs as backward or more backward.
It had also observed that it is not impermissible in law if state chooses to do sub-categorization.
So far, 11 states/UTs viz. Karnataka, Haryana, Andhra Pradesh, Jharkhand, Puducherry, Telangana, West Bengal, Bihar, Maharashtra, Tamil Nadu and Jammu region of Jammu & Kashmir have carried out sub-categorization of OBCs.
However, there was no sub categorisation in central list of OBCs.
