The main work of the commission is to participate and advise actively on the socio-economic development of the socially backward classes (OBCs) along with evaluating the progress of their development. Statutory backing 
The commission was the outcome of Indra Sawhney & Others v. Union of India. The Supreme Court of India in its Judgement dated 16.11.1992 in Writ Petition (Civil) No. 930 of 1990 – Indra Sawhney & Ors. Vs. Union of India and Ors., reported in (1992) Supp. 3 SCC 217 directed the Government of India, State Governments and Union Territory Administrations to constitute a permanent body in the nature of a Commission or Tribunal for entertaining, examining and recommending upon requests for inclusion and complaints of over-inclusion and under-inclusion in the list of OBCs. The Supreme Court held that the Constitution recognised only social and educational – and not economic – backwardness. The number of backward castes in Central list of OBCs has now increased to 5,013+ (without the figures for most of the Union Territories) in 2006 as per National Commission for Backward Classes. In October 2015, National Commission for Backward Classes proposed that a person belonging to OBC with an annual family income of up to ₹15 lakhs should be considered as minimum ceiling for OBC. NCBC also recommended sub-division of OBCs into 'backward', 'more backward' and 'extremely backward' blocs and divide 27% quota amongst them in proportion to their population, to ensure that stronger OBCs don't corner the quota benefits.
