Other Backward Classes

Other Backward Classes — reservation, sub-categorisation

Story hook

It is 7 August 1990. Prime Minister V.P. Singh rises in Parliament to announce that his government will implement the Mandal Commission Report — 27% reservation for Other Backward Classes in Central Government jobs. Within hours, Rajiv Goswami, a Delhi University student, sets himself on fire outside Deshbandhu College. Over 159 self-immolations follow over the next three months. The country tilts on the axis of caste-based affirmative action.

Cut to 1 January 2017. The Modi government appoints Justice G. Rohini to head a Commission under Article 340 to sub-categorise the OBC list — to split the 27% into pockets reserved for the most-deprived OBC sub-groups. The Commission's tenure extended 14 times to date; the report submitted in August 2023 awaits political action.

For UPSC, OBCs are the largest under-served group — estimated 41-52% of India's population (Mandal 1980 said 52%; NSSO 2006 said 41%; Bihar caste survey 2023 said 63% in that state). The 27% reservation, the Indra Sawhney 9-judge bench (1992), the 102nd Amendment 2018 (constitutionalising NCBC), the 103rd EWS Amendment 2019 (which excludes OBCs from its 10% quota), the 105th Amendment 2021 (restoring state power to identify SEBC), and the Rohini Commission 2017-23 are all examinable.
