OBCs & the Reservation System

GS Paper: GS Paper I (Social Empowerment) | Subject: Social Issues | Last updated: 2026-06-24

Class 2 (Sahil Goyal, 12-06-2026). Continues from the caste foundation in lec01. It covers the fourth caste group becoming "OBC," how OBCs were identified (Article 340 → Mandal), the reservation system (Articles 15 & 16; equality vs equity), the landmark Indra Sawhney (1992) case (creamy layer, 50% cap, sub-classification), caste politics after 1990, and the OBC / SC-ST list mechanics. The class ends by opening untouchability, which is taken up in lec03.

1. Who are the OBCs? — Article 340 → Mandal

Recall the six caste groups (lec01): groups 4 (peasant/agrarian) and 5 (artisan) are the lower castes that, in modern India, acquired the identity OBC — Other Backward Classes. The British, after their censuses, had drawn up lists of SCs (those suffering the stigma of untouchability) and STs (forest-dwelling communities), but never created an "OBC" list. After Independence, the government had to identify the OBCs itself.

TEACHER'S NOTE (the constitutional hook — Article 340): When the Constitution came into force (1950), Article 340 provided that the President (i.e. the Government of India) shall appoint a Commission to identify the socially and educationally backward classes (SEBC). Note the terminology trap: the Constitution uses "SEBC," not the word "OBC" — but the two refer to the same group. (No such commission was needed for SC/ST, because the British had already identified them.)

How OBCs were identified and given reservation — Art 340 to Indra Sawhney

TEACHER'S NOTE (how Mandal built the OBC list): Mandal picked up the 1931 caste census (the last caste census available), removed the upper castes (who were never victims of historic injustice and need no reservation) and the untouchables/SCs (already getting reservation), and from the remaining castes went into the field to survey each caste's social and educational condition — e.g. what occupation do they do (manual/sweating work → low social status) and what is their education level (not even 10th-pass → educationally backward). Only castes found to be both socially and educationally backward were classified as OBC, with survey data to prove the backwardness. Mandal estimated OBCs at ~52% of India's population (the teacher at one point said ~65%; the citable Mandal figure is 52%) and recommended 27% reservation for OBCs in government jobs and higher-education institutions (IITs/NITs etc.). Mandal submitted its report in 1980.

2. The reservation system — Articles 15 & 16

Reservation flows from two Fundamental-Rights articles:

CLARIFICATION (why a separate Article 16 at all?): Article 16 could almost be derived from Article 15 — but public employment in India carries great prestige, so the framers wrote a separate equality-in-jobs guarantee. (Again, the Constitution's word is "SEBC," not "OBC.")

3. Why reservation: the law of equity

Why give reservation at all? Because SCs, STs and OBCs have been victims of historic injustice and discrimination under the caste system. The children of these communities carry a historic disadvantage and cannot compete on equal terms with upper-caste children. To give them a genuinely equal opportunity, the state provides reservation.

TEACHER'S EXAMPLE (equality vs equity): Justice is not only equality; it is also equity. - Law of equality = equals must be treated equally (equality of opportunity). - Law of equity = UNequals must be treated UNequally (special provisions for the backward). India must follow equity because it has a huge population of "unequals" — the backward / vulnerable / disadvantaged sections (keep these three words; they all mean the same group). His analogies: (1) if boys study full-time but girls are married and burdened with housework, setting the same paper for both is injustice — equity means easing the paper for the disadvantaged; (2) three viewers of different heights behind a wall watching a cricket match — making them all stand on the same ground means the short ones still can't see (formal equality), whereas giving each a stool — a bigger one to the shorter — lets everyone see (equity), and that stool is reservation.

Clean version (study from this):

Why reservation — the law of equity, not just equality

4. Indra Sawhney (1992)

When OBC reservation began in 1990, the general category challenged it in court, and the Supreme Court ruled in Indra Sawhney v. Union of India (1992) — the Mandal case. (The teacher kept the polity detail brief; the social-justice takeaways:)

The Court upheld the 27% OBC reservation and laid down guidelines for the state:

  1. Reservation only for the socially & educationally backward, and that backwardness must be proved using quantifiable data (measurable — e.g. % not educated).

  2. No OBC reservation without first identifying the "creamy layer."

    CLARIFICATION (creamy layer — families, not castes): The creamy layer is the set of families within the OBCs that are socially & educationally forward, who therefore don't need reservation and are excluded from it. The Court fixed no rigid definition (States and the Centre set criteria), but indicated that children of Group-A/Group-B officers, or of those holding high constitutional posts (MP, Speaker, judge), enjoy good social status irrespective of income and so fall in the creamy layer. (Example: the family of a senior OBC politician like an Akhilesh Yadav would be creamy layer.) Creamy layer applies to OBCs only — the Court itself said it does not apply to SC/ST reservation (but see lec03 — M Nagaraj 2006 and Davinder Singh 2024 changed this for SC/ST).

  3. Sub-classification of OBCs is allowed (permitted, not compulsory).

    CLARIFICATION ("reservation within reservation"): Within the OBC bloc, some castes are far more backward than others. Sub-classification splits the OBC list into EBC (extremely backward) / MBC (more backward) / other OBCs and earmarks a fixed slice of the 27% for each. It makes reservation more inclusive — ensuring the benefit reaches the "weakest of the weak" (the last mile). Without it, the less-backward OBC castes corner most reserved seats (the Rohini Commission found ~15% of OBC castes were taking ~90% of OBC reserved seats).

Clean version (study from this):

Reservation breakdown and the 50% ceiling

Sub-classification of OBCs — reservation within reservation

CURRENT AFFAIRS (Rohini Commission & the caste census): In 2017 the Centre appointed the Rohini Commission to sub-categorise OBCs; it favoured sub-classification but the Centre has not yet sub-classified the central OBC list, arguing it lacks EBC/MBC population data to fix the slices — one of the reasons cited for conducting the 2026 caste census. (Note the recurring teacher theme: a caste census makes reservation more effective but risks re-hardening caste.)

EXAM FOCUS (the 50% ceiling): Indra Sawhney also capped total reservation at ~50%. SC (15%) + ST (7.5%) + OBC (27%) = 49.5%, just under it. (The EWS 10% quota, 103rd Amendment 2019, sits outside this caste ceiling — beyond today's class but worth knowing.)

5. Caste politics after 1990

TEACHER'S NOTE (the rise of caste politics): After 1990 the central government fell, but regional political parties rose in North India, organised on caste lines — the Samajwadi Party (mobilising Yadavs of UP), the RJD (Yadavs of Bihar), the INLD (Haryana). How did they form so fast? Because the caste associations already existed — the very groups that, after the 1891 census, had petitioned the British for upper-caste status (lec01). After Mandal showed that OBCs are the majority of India's population, these associations simply converted into political parties and mobilised votes on the basis of caste ("people were not casting their vote, they were voting their caste"). So after 1990, caste became the most important factor in Indian politics — the "casteisation of politics" / politicisation of caste — with OBCs dominating.

EXAM FOCUS (Mandal vs Kamandal): Mandal politics = the caste politics of OBCs (post-1990). Kamandal politics = the rise of religion-based (Hindutva) politics (the BJP), covered later under communalism. The shorthand: after 1990, caste replaced earlier alignments; after 2014, religion began replacing caste as the dominant axis of Indian politics. (This thread continues in lec03's section on right-wing politics.)

6. The OBC and SC/ST lists

TEACHER'S NOTE (list mechanics — a favourite Prelims area): - OBCs have two lists — a Central List (in force from 1990) and a State List that every state maintains. The two are independent of each other: a caste may be in a State list but not the Central list, or vice-versa. The Centre controls/amends the Central list; each State controls its own. For OBC reservation in central exams you must be in the Central list; for a State's civil services you must be in that State's list — being in one does not give you the other. (Inclusion always needs a survey proving social & educational backwardness; the Centre may use a state's survey or do its own, and vice-versa.) - SC/STs have only one list — the Central List (there is no state SC/ST list); states give SC/ST reservation on the basis of the Central list. - Both the SC/ST and OBC central lists are categorised state-wise — because caste has regional variation (a caste that is SC in UP, e.g. Chamar, may not exist in Punjab). So it is one central list, divided state by state. - Caste is tied to domicile: a person who is SC in Haryana gets SC reservation in Haryana's services and in central (UPSC) exams, but is treated as general in another state's exams.

CLARIFICATION (the census made caste rigid — and may again): What made a once-fluid caste rigid? The caste census (British, 1871→1931) that listed castes as upper/lower. The teacher flags that the 2026 caste census could likewise revive and re-harden caste even as it aims to make reservation and OBC welfare more effective.

7. Exam focus — the caste PYQ pattern

EXAM FOCUS (how to write caste answers — the teacher's method): Almost every caste PYQ (2018, 2020, 2023…) asks one underlying question — will caste survive / what keeps it alive / why can't India become casteless? So one stock introduction serves them all: "Caste is assuming new identities and associational forms, and therefore keeps itself alive / relevant." Write simple, logical, three-part answers (intro–body–conclusion) in plain language — no data, no quotations needed. Build the body from the recurring points: - New identities: caste is no longer tied to occupation (dissociation, esp. urban); it has gained a political identity (caste parties + reservation) and the "dominant caste" identity. - Associational forms: caste-based regional parties; urban caste associations/"samaj" (matrimony, schools, hostels, coaching, WhatsApp/Facebook groups); rural caste panchayats. - Reservation ↔ caste loop: caste led to reservation, and now reservation keeps caste alive — reservation makes caste both static (you must stay in your caste to claim it) and fluid (it lets lower-caste people change occupation — become doctors, IAS officers). The state lets you change religion and occupation, but never caste. - Where caste is more vs less relevant: still very relevant in rural areas (marriage, power dynamics, politics, reservation, occupation for agrarian castes) and for lower castes (reservation, politics, welfare); its relevance has declined in urban areas (occupation dissociation, modernisation, constitutional/legal measures like abolition of untouchability). - Conclusion: caste keeps reinventing itself → it remains relevant and alive, and will continue to be so.
