Sub-categorisation of OBCs

Meaning

Sub-categorisation of OBCs means dividing the OBC quota (27% in central jobs and seats) into smaller sub-groups. Each sub-group gets its own share, so the more backward castes are not crowded out by stronger OBC castes. It matters because a few OBC castes have taken most of the benefits. Any split must rest on hard, comparative data, or courts can strike it down under Article 14 (equality before the law).

Explanation

Why it is needed

  • The OBC list is not one equal group
  • The Mandal Commission identified 3,743 castes as OBCs. They differ widely in land, education and jobs.

  • When all of them compete for one 27% quota, the better-off castes win most seats and posts.

  • The Rohini Commission's 2018 analysis showed this clearly

  • About a quarter of the castes on the central OBC list took about 97% of jobs and seats (verify figures).

  • Nearly a thousand castes got nothing (verify figures).

  • Aim: to make sure the benefit reaches the most backward. It is not to change the total size of the quota.

How it works

  • The total OBC quota stays the same. Only the way it is shared changes.
  • The OBC list is split into categories, such as "backward" and "more backward". Each category gets a fixed part of the quota.
  • An example of how it is done: Bihar's split of backward classes into EBCs (Extremely Backward Classes) and BCs. Many states already sub-categorise in this way.
  • Who can do it
  • The Union can sub-categorise the central list. The Rohini Commission was set up for this purpose.
  • States can sub-categorise their own lists. The 105th Amendment (2021) restored their power to make SEBC lists, through Art. 342A(3).

Conditions and limits

  • Indra Sawhney (1992) held that backward classes may be split into "backward" and "more backward". So sub-categorisation is allowed in principle.
  • The data must compare groups, not just count people
  • In 2022 the Supreme Court struck down Tamil Nadu's 10.5% internal quota for Vanniyars inside the Most Backward Classes (MBC) quota.
  • The Court found "no substantial basis" for treating Vanniyars differently from the other 115 MBC communities. So the quota failed the Article 14 test.

  • The lesson: the state must show how each sub-group compares with every other group in the same list.

  • The data must be recent and in numbers

  • The Maratha judgment (Jaishri Laxmanrao Patil, 2021) asked for quantifiable and contemporaneous data, meaning data in numbers collected close to the time of the decision. The Court said this for quotas above 50%, but the same idea of data-based policy guides sub-quotas too.

  • It does not lift the 50% ceiling

  • Sub-categorisation shares out the existing quota. It cannot be used to cross the Indra Sawhney limit of 50%, which can be crossed only in extraordinary situations.

  • It cannot be based on religion alone

  • A sub-quota within the OBC quota for minorities as a whole fails in court. A 4.5% minority sub-quota inside the OBC quota (December 2011) was struck down by the Andhra Pradesh High Court in 2012.

In the Constitution and practice

  • Constitutional basis
  • Art. 15(4) and Art. 16(4) are enabling powers: the state may make special provisions and reserve posts for backward classes. Sub-categorisation is a way of using these powers.
  • Art. 340: the President may appoint a commission to study backward classes. The Kalelkar (1953/55) and Mandal (1979/80) Commissions were set up under this article.
  • 102nd Amendment (2018): the NCBC (National Commission for Backward Classes) became a constitutional body under Art. 338B. It also added Art. 342A on presidential notification of SEBCs.

  • 105th Amendment (2021): restored states' power to keep their own SEBC lists through Art. 342A(3) and an amended Art. 366(26C).

  • Early idea: the Kalelkar Commission (report 1955) marked 837 of 2,399 backward castes as "most backward".

  • Rohini Commission
  • It was set up on 2 October 2017 to sub-categorise OBCs in the central list.
  • It received 14 extensions and submitted its report on 31 July 2023.

  • The report has not been made public.

  • In the states

  • Bihar has an EBC/BC split.
  • Tamil Nadu's 10.5% Vanniyar internal quota was struck down in 2022 for lack of comparative data.

  • Andhra Pradesh's 4% BC-E quota (2007) for backward Muslim groups continues under an interim Supreme Court order.

  • New data sources

  • Census 2027 will record "SC/ST/Caste". This is the first count of castes other than SCs and STs since 1931.
  • Telangana's survey covered socio-economic, educational, employment, political and caste data. It put OBCs at 56.36% of the population.

Don't confuse with

  • Sub-classification of SCs: this splits the SC quota, not the OBC quota. E.V. Chinnaiah (2004) had held that SCs form one homogeneous (uniform) class. State of Punjab v. Davinder Singh (2024, 6:1) overruled that view. Sub-categorising OBCs never faced this bar, because Indra Sawhney (1992) already allowed a "backward" and "more backward" split.
  • Creamy layer: this removes better-off individuals or families from OBC benefits, using parents' posts and the ₹8 lakh income limit. Sub-categorisation works on castes or groups, giving each its own share.
  • Horizontal reservation: quotas for women, persons with disabilities and ex-servicemen cut across the social-group blocks. Sub-categorisation divides one vertical block (the OBC quota) into smaller vertical shares.
  • Religion-based reservation: a quota for a whole religion fails in court. Backward groups within a religion can benefit only if they are listed as OBCs, as in Kerala.

Prelims Hooks

  • Rohini Commission: set up 2 October 2017; given 14 extensions; report submitted 31 July 2023; report not public.
  • Indra Sawhney (1992) allowed backward classes to be split into "backward" and "more backward". This is the legal basis for sub-categorising OBCs.
  • Vanniyar internal quota (10.5%, Tamil Nadu) was struck down in 2022. It had no substantial basis to set Vanniyars apart from 115 other MBC communities.
  • Art. 342A(3), added by the 105th Amendment (2021), restored states' power over their own SEBC lists. Art. 338B, added by the 102nd Amendment (2018), made the NCBC a constitutional body.
  • Trap: "Sub-categorisation raises the total OBC quota above 27%." FALSE. It only shares out the existing quota.
  • Trap: "Indra Sawhney barred splitting backward classes." FALSE. It allowed it. The bar on splitting SCs came from Chinnaiah (2004) and was removed by Davinder Singh (2024).

Mains Points

  • Fairness vs dominance: a few OBC castes hold most of the gains, while nearly a thousand get nothing (Rohini 2018 analysis, verify figures). Sub-categorisation spreads the benefit more widely. But Class 11 Equality warns that differential treatment must not create "new structures of dominance". Sub-quotas should also be reviewed from time to time, so they do not lock groups in permanently.
  • Data is the real test: courts now judge quotas by comparative, recent data. Census 2027 caste counts and detailed state surveys like Telangana's can supply this data. Publishing the Rohini report and its method would make any central sub-categorisation easier to defend and less open to the charge of vote-bank politics.
  • Federal and political angle: the Union can sub-categorise the central list and states can sub-categorise their own lists (Art. 342A(3)), so the same caste may be in different categories in different lists. Sub-categorisation also cannot get around the 50% ceiling. So a state's realistic choice is to share its existing quota fairly, not to make it bigger.
