Special Provisions for SC, ST, OBC, Anglo-Indians

Part XVI of the Constitution — Articles 330 to 342 — is the political and administrative scaffolding that holds up the substantive guarantees of equality. Where Article 15(4) and Article 16(4) authorise the State to make special provisions, Part XVI fixes the seats in legislatures, the safeguards in services, the Presidential lists that identify beneficiaries, and the National Commissions that police compliance. Article 342A, inserted by the 102nd Amendment, completes the architecture by extending the Presidential-list mechanism to socially and educationally backward classes. Read together with the broader framework of equality under Articles 14 to 16, Part XVI is the operational arm of India's affirmative-action constitutionalism.

The chapter matters for the exam-aspirant for one structural reason. Most reservation litigation — M.R. Balaji, Indra Sawhney, M. Nagaraj, Jarnail Singh, Janhit Abhiyan — turns on Articles 14, 15 and 16. But the identifications, the percentages, the commissions, the political reservations and the Anglo-Indian story all sit in Part XVI. Confuse the two clusters and you forfeit easy marks.

Article 330 — Reservation of Lok Sabha seats for SC and ST

Article 330(1) reserves seats in the House of the People for the Scheduled Castes, for the Scheduled Tribes (other than those in the autonomous districts of Assam) and for the Scheduled Tribes in those autonomous districts as a separate category. Clause (2) anchors the arithmetic: the number of reserved seats for any State or Union territory bears, as nearly as may be, the same proportion to that State's allotment in the Lok Sabha as the SC or ST population bears to its total population. The Explanation freezes the population figure to the last preceding census whose figures have been published, with a proviso that — until the first census after 2026 is published — the 2001 census continues as the reference base.

The character of this reservation has been clarified in Giri V.V. v. Dora Dippala Suri (AIR 1959). Reservation guarantees a minimum number of seats; it does not strip a member of the Scheduled Caste of the right to contest a general seat. He may contest both, on the strength of a single nomination. In a multi-member constituency, if a second SC candidate polls the highest votes for the general seat, nothing prevents his return on that seat. The protection is a floor, not a ceiling. The rules of election machinery and electoral rolls under Articles 324 to 329 remain the working law for everything else.

The identification of who is to be counted as SC for the purposes of reservation under Article 330 must follow the Presidential Order under Article 341 strictly. S. Pushpa v. Sivachanmugavelu (2005) holds that the population of migrant Scheduled Castes from another State cannot be added in for the purpose of computing the seats — the exercise is State-relative.

Article 331 — Anglo-Indian nomination to the Lok Sabha (now spent)

Article 331 empowered the President to nominate not more than two members of the Anglo-Indian community to the House of the People if he was of the opinion that the community was not adequately represented. The provision was a transitional concession to a numerically small but socially distinct community. Following the Constitution (104th Amendment) Act, 2019, the power of nomination under Article 331 has expired with effect from 25 January 2020. The community is no longer separately represented by nomination. The reservation of SC and ST seats was simultaneously extended for ten years; the Anglo-Indian seats were not.

Article 332 — Reservation in State Legislative Assemblies

Article 332 mirrors Article 330 for the State legislatures: seats are reserved for SCs and STs (other than the STs in the autonomous districts of Assam) in the Legislative Assembly of every State, with the population-proportion rule of clause (3) replicating the Lok Sabha formula. Special arithmetic clauses (3A) and (3B) — inserted by the 57th Amendment (1987) and 72nd Amendment (1992) — protect the existing tribal share in the Legislative Assemblies of Arunachal Pradesh, Meghalaya, Mizoram, Nagaland and Tripura, until the first post-2026 census takes effect under Article 170. Clauses (5) and (6) ensure that the autonomous-district constituencies remain ethnically true: the constituencies cannot extend beyond the district, and only members of an Assam Scheduled Tribe of that district may be elected from it. The detailed working of the State legislature, including delimitation under Article 170, is the broader frame within which clauses (3A) and (3B) operate.

The constitutional validity of Article 332 itself was placed beyond doubt in R.C. Poudyal v. Union of India (1994): the express reservation of seats provided under Article 332 cannot be challenged on the ground of denial of equality under Article 14. The reservation is a constitutional choice, not a legislative one. Two later decisions sharpen its scope. Sobha Hymavathi Devi v. Setti Gangadhara Swamy (2005) holds that a non-tribal woman cannot, by marriage to a tribal man, become eligible to contest a seat reserved for a Scheduled Tribe; reservation under Articles 15(4), 16(4), 330 or 332 benefits only those who actually belong to a Scheduled Caste or Scheduled Tribe. Satrucharia Vijaya Rama Raju v. Nimmaka Jaya Raju (2006) extends the same reasoning to candidates who do not represent the tribe as a true representative.

Article 333 — Anglo-Indian nomination to State Assemblies (also spent)

Article 333 enabled the Governor to nominate one member of the Anglo-Indian community to the Legislative Assembly of a State on the same opinion-based test. Like Article 331, this nomination power was discontinued by the 104th Amendment with effect from 25 January 2020.

Article 334 — The sunset clause and the 104th Amendment

Article 334 is the constitutional clock on Part XVI. As originally drafted, it provided that the reservation of SC and ST seats in the Lok Sabha and the State Assemblies, and the nomination of Anglo-Indians to those bodies, would cease ten years from the commencement of the Constitution. Successive amendments — the 8th, 23rd, 45th, 62nd, 79th and 95th — extended this period in ten-year tranches. The Constitution (104th Amendment) Act, 2019 made two surgical changes:

1. The reservation of seats for SCs and STs in the House of the People and the State Legislative Assemblies was extended by ten years, until 25 January 2030 (i.e., seventy years from commencement).
2. The provision for nomination of Anglo-Indians under Articles 331 and 333 was not extended; it lapsed on 25 January 2020.

The proviso to Article 334 ensures that the lapse does not unseat a sitting member: any representation existing at the moment of expiry continues until the dissolution of the then-existing House or Assembly. This was the route by which sitting Anglo-Indian nominees in some State assemblies completed their terms after 2020.

Article 335 — Claims of SC and ST in services

Article 335 is the second pillar of Part XVI: it requires the State, in making appointments to services and posts under the Union or a State, to take into consideration the claims of the members of the Scheduled Castes and the Scheduled Tribes, consistently with the maintenance of efficiency of administration. The proviso, inserted by the 82nd Amendment (2000), permits relaxation of qualifying marks and lowering of standards of evaluation for reservation in matters of promotion. The article is the doctrinal hinge between affirmative action and administrative competence, and operates alongside the rest of Part XIV on services under the Union and the States.

Three holdings shape the field. First, the State has a constitutional duty to consider the claims of SCs and STs in service appointments — Comptroller and Auditor-General v. K.S. Jagannathan (AIR 1987) — and the duty must be discharged in keeping with the directive in Article 46 to promote the educational and economic interests of the weaker sections. The Article reaches every agency falling within Article 12 of the Constitution. Second, the proviso operates only for promotions; A.P. Public Service Commission v. Baloji Badhavath (2009) refuses to read it back into direct recruitment as a constitutional command. Third, the relaxation enabled by the proviso must not collapse the qualifying threshold altogether — minimum standards may be relaxed but not omitted. Service rules that allowed SC/ST/BT candidates to bypass the selection process altogether were struck down as ultra vires Articles 16 and 335 in State of Karnataka v. Kumari Gowri Narayana Ambiga (1995).

The Indra Sawhney synthesis: 50%, OBC, creamy layer

The reconciliation between reservation under Article 16(4) and efficiency under Article 335 was settled by the nine-judge Bench in Indra Sawhney v. Union of India (1992). The propositions that govern the field today are six. (i) Reservation is not necessarily anti-meritarian, because efficiency is not identical with examination merit. (ii) The condition of efficiency in Article 335 attaches to appointments of OBC candidates as well, not only SC/ST. (iii) Some sacrifice of merit is the constitutional cost of social justice. (iv) For Article 16(4), the claimants must belong to a backward class and that class must be inadequately represented in the services under the State; both are objective inquiries open to judicial review on Barium Chemicals grounds. (v) A reservation of 27% for OBCs is valid provided the total reservation, including SC and ST, does not exceed 50% in any year. (vi) The 50% ceiling may be exceeded only in extraordinary situations, such as remote areas with deeper backwardness; merit-selected SC/ST candidates do not count against the 50% quota; and reservations under Article 16(1) for handicapped persons are computed separately.

Indra Sawhney also restored the carry-forward rule that Devadasan v. Union of India (AIR 1964) had struck down, subject to the cap that the carry-forward must not breach the 50% limit in any year. And it carved out a separate category of services where the nature of the post — research and development, super-specialities in medicine and engineering, defence services, scientific establishments, pilots — calls for the highest skill and where reservation should not apply.

Promotional reservation: M. Nagaraj and Jarnail Singh

The propositions in Indra Sawhney that promotional reservation undermines efficiency and violates Article 335 — overruling General Manager, Southern Railway v. Rangachari (AIR 1962) — were neutralised by the legislature through the 77th Amendment (1995), the 81st Amendment, the 82nd Amendment (2000), and the 85th Amendment (2001). These inserted Articles 16(4A) and 16(4B) and added the proviso to Article 335. The constitutional validity of these amendments was upheld in M. Nagaraj v. Union of India (2006), but with three controlling conditions: the State must collect quantifiable data showing (a) backwardness of the class, (b) inadequacy of representation in the cadre concerned, and (c) the impact on overall efficiency under Article 335. Nagaraj reads the efficiency proviso to Article 335 as conferring discretion on the State, but never erasing the limitation: efficiency is a variable, and the State must show how it has been preserved.

Jarnail Singh v. Lachhmi Narain Gupta (2018) refined Nagaraj on two points. The requirement of demonstrating the backwardness of SCs and STs as a precondition to promotional reservation was held to be invalid — they are presumptively backward by reason of their inclusion in the Presidential lists under Articles 341 and 342 — but the requirement of quantifiable data on inadequacy of representation in the cadre, and the test of overall efficiency, both survive. Jarnail Singh also extended the creamy-layer principle of Indra Sawhney to SC and ST candidates for the purposes of promotional reservation. The decision in S. Panneerselvam v. State of Tamil Nadu (2015) had earlier confirmed that Article 16(4A) is an enabling provision, not a constitutional mandate; Mukesh Kumar v. State of Uttarakhand (2020) treated this as fundamental — no individual has an enforceable right to insist that a State exercise its discretion to provide promotional reservation.

Articles 336 and 337 — Anglo-Indian services and education (now spent)

Articles 336 and 337 protected the Anglo-Indian community's pre-Constitution share in railway, customs, postal and telegraph services and the educational grants made for the community on the eve of independence. Both schemes were tapering: the service quotas reduced by ten percent every two years and ceased after ten years; the educational grants reduced by ten percent every three years and ceased after ten years. Article 336 has long been spent. Article 337 was held to have ceased in Frank Anthony Public School Employees' Association v. Union of India (AIR 1987) — there is no longer any constitutional right of Anglo-Indian educational institutions to receive special protection under that Article.

Articles 338, 338A and 338B — The three National Commissions

The Constitution sets up three statutory-strength commissions for the protection of historically marginalised communities. Article 338 establishes the National Commission for Scheduled Castes; Article 338A, inserted by the 89th Amendment (2003), the National Commission for Scheduled Tribes; and Article 338B, inserted by the 102nd Amendment (2018), the National Commission for Backward Classes. Each commission consists of a Chairperson, Vice-Chairperson and three other members appointed by the President. Each has the duty to investigate and monitor safeguards, inquire into specific complaints, advise on planning and report annually to the President; reports concerning a State are forwarded to the Governor for tabling in the Legislature.

The investigative powers in clause (8) are those of a civil court — summoning witnesses, requiring discovery, receiving evidence on affidavit and requisitioning records. But the Commission cannot grant injunctions, permanent or temporary: All India Indian Overseas Bank SC and ST Employees' Welfare Association v. Union of India (1996). The protection-and-welfare clause has also justified statutes that exclude the operation of ordinary criminal procedure protections such as anticipatory bail under Section 438 CrPC from offences under the Scheduled Castes and Scheduled Tribes (Prevention of Atrocities) Act, 1989: State of M.P. v. Ram Krishna Balothia (1995).

Article 339 — Union control over Scheduled Areas

Article 339 has two limbs. Clause (1) empowered the President to appoint a Commission to report on the administration of the Scheduled Areas and the welfare of the Scheduled Tribes — once at the expiration of ten years from commencement, and at any time thereafter. Clause (2) extends the executive power of the Union to giving directions to a State as to the schemes essential for the welfare of the Scheduled Tribes. The Article is the bridge between Part XVI and the Fifth and Sixth Schedules; it sits within the larger fabric of special provisions relating to certain States under Articles 370 and 371, both of which carry their own protections for tribal-majority regions.

Article 340 — The Backward Classes Commissions

Article 340(1) empowers the President to appoint a Commission to investigate the conditions of socially and educationally backward classes and to recommend the steps that should be taken by the Union or any State for their improvement. The First Backward Classes Commission, chaired by Kaka Kalelkar (1953), produced an inconclusive report. The Second Backward Classes Commission, chaired by B.P. Mandal (1979), submitted its report in 1980; its central recommendation that 27% of Central Government posts be reserved for OBCs was implemented in 1990 and was the immediate trigger for Indra Sawhney.

In exercise of the Article 340 power read with the directions in Indra Sawhney, Parliament enacted the National Commission for Backward Classes Act, 1993. The Act vested the Central Government with the initial identification of backward classes (other than SCs and STs) and conferred on the Commission an advisory power that was, in practice, ordinarily binding: where the Centre departed from the Commission's advice, the reasons had to be reported to Parliament. Lists were to be revised every ten years. The 102nd Amendment then constitutionalised the Commission as Article 338B and added the new mechanism in Article 342A.

Articles 341, 342 and 342A — The Presidential lists

Article 341 is the source of the SC list. Clause (1) empowers the President, with respect to any State or Union territory and after consultation with the Governor where it is a State, to specify by public notification the castes, races or tribes — or parts of or groups within them — which shall, for the purposes of the Constitution, be deemed to be Scheduled Castes in relation to that State or Union territory. Clause (2) reserves the power of variation to Parliament alone: the list, once notified, can be amended only by parliamentary law. Article 342 replicates the scheme for Scheduled Tribes. Article 342A, inserted by the 102nd Amendment (2018) and amended by the 105th Amendment (2021), creates a parallel Presidential list for socially and educationally backward classes and — after the 105th Amendment, prompted by Jaishri Laxmanrao Patil v. Chief Minister (2021) on the Maratha reservation — restores to State governments the power to identify SEBCs for State lists.

The settled propositions on the SC list are these. The only authority competent to issue the original notification is the President: Shree Surat Valsad Jilla K.M.G. Parishad v. Union of India (2007). Once issued, the list is exhaustive; the courts have no jurisdiction to inquire into whether some other community is by analogy or synonym a Scheduled Caste, beyond reading the entries as they stand: Bhaiyalal v. Harikishan Singh (AIR 1965); Palghat Jilla Thandan Samudhaya Samrakshna Samiti v. State of Kerala (1994). Even literal synonyms — Dhoba and Rajaka, for instance — may be admitted only where the Order itself recognises them. State of Maharashtra v. Milind (2001) reaffirms that a school-leaving certificate is not conclusive proof of caste, that the word "caste" in Article 341 carries the special meaning of Article 366(24) and not its ordinary sociological sense, and that the President may include only parts of a caste or only the members in particular districts.

Equally settled are the propositions on identity and migration. A person inherits caste from the father; the mother's status alone cannot ordinarily ground an SC claim — Punit Rai v. Dinesh Chaudhary (2003). A migrant SC/ST of one State cannot claim reservation in another State as a member of the same community: Action Committee on Issue of Caste Certificate to SC and ST in State of Maharashtra v. Union of India (1994); Subhash Chandra v. Delhi Subordinate Services Selection Board (2009). But migration does not erase the underlying status — the person does not, by migration, become a member of a forward caste: S. Pushpa (2005). On conversion, a person who professes Buddhism (or another non-Hindu/Sikh religion) cannot claim SC status; on reconversion to Hinduism, status revives if the community accepts him: C.M. Arumugan v. S. Rajgopal (AIR 1976). And the unbroken thread through these decisions is that any procurement of a bogus caste certificate is a fraud on the Constitution and entitles the State to cancel the certificate following the procedure in Kumari Madhuri Patil v. Addl. Commissioner, Tribal Development (1994).

On Scheduled Tribes, Article 342 mirrors Article 341. Two questions recur. Marriage: a non-tribal woman who marries a tribal man does not automatically become a Scheduled Tribe; the village community must accept her by resolution, and even then the question of disability — having actually suffered the disabilities the reservation seeks to remedy — survives, as Anjan Kumar v. Union of India (2006) holds. Conversion: tribal status is a question of fact, and a tribal who changes religion may continue to be a member of the tribe if he continues to follow the tribal traits and customs (State of Kerala v. Chandramohanan, 2004).

Creamy layer and the EWS overlay

Two strands of doctrine close the field. The creamy-layer rule — that the socially advanced members of a backward class must be excluded from the benefit of reservation, lest the benefit ossify into a hereditary entitlement — was laid down in Indra Sawhney for OBCs. Jarnail Singh extended it to SC/ST candidates for the limited purpose of promotional reservation; E.V. Chinnaiah v. State of Andhra Pradesh (2005) had earlier held that any creamy-layer demarcation within the SC list must be done by Parliament under Article 341(2), since the SC list is a homogeneous group that the State legislature cannot fragment. The position on sub-classification within the SC list is currently being re-examined by larger benches; the working rule is the rule in E.V. Chinnaiah.

The 103rd Amendment (2019) inserted Articles 15(6) and 16(6), creating a 10% reservation for the Economically Weaker Sections among citizens not covered by Articles 15(4), 15(5) and 16(4) — i.e., excluding SCs, STs and OBCs. The amendment was upheld by a 3:2 majority in Janhit Abhiyan v. Union of India (2022). EWS sits outside Part XVI in the structural sense — it does not flow through the Articles 341/342/342A list mechanism — but it is the contemporary frame in which Part XVI now operates. Read against K. Krishna Murthy v. Union of India (2010), which dealt with reservation in local bodies and Panchayats, the constitutional architecture for political and educational reservation now operates on three identification streams — SC, ST, OBC/SEBC — overlaid by EWS.

Exam takeaways

For the judiciary aspirant, four high-value pegs hang from this chapter. (i) Article 334 and the 104th Amendment: SC/ST reservation in Lok Sabha and Assemblies extended to 25 January 2030; Anglo-Indian nominations under Articles 331 and 333 lapsed on 25 January 2020. (ii) Article 335 and the proviso: efficiency is the constitutional limitation; the proviso permits relaxation in promotion only, and even then minimum standards cannot be omitted. (iii) Indra Sawhney → Nagaraj → Jarnail Singh → Mukesh Kumar: the 50% ceiling, the OBC creamy layer, the quantifiable-data test for promotional reservation, the dropping of the backwardness test for SC/ST in Jarnail Singh, and the absence of any enforceable individual right to insist on reservation. (iv) The Presidential lists under Articles 341, 342 and 342A: only the President may notify; only Parliament may vary; courts cannot inquire into entries by analogy or synonym; migration does not erase status but cannot be carried across State boundaries for reservation purposes.

For the cluster of doctrinal links, this chapter sits next to the substantive equality framework of Articles 14 to 16, the services framework of Part XIV, the Lok Sabha composition and delimitation under Articles 81 and 82, and the larger Article 368 amendment regime through which every change in Part XVI has been routed. Anyone preparing for state judiciary or CLAT PG should treat the four sets of provisions — Article 330/332 (political), 335 (services), 338 series (commissions) and 341/342/342A (lists) — as a single examinable cluster, and should hold the comprehensive map of the Constitution of India notes firmly in view when locating any single decision in its right place.

Frequently asked questions

What did the 104th Constitutional Amendment do to Anglo-Indian reservation?

The Constitution (104th Amendment) Act, 2019 made two changes to Article 334. It extended the reservation of seats for Scheduled Castes and Scheduled Tribes in the House of the People and the State Legislative Assemblies for ten years, until 25 January 2030. It did not extend the provision for nomination of Anglo-Indians under Articles 331 and 333 — that provision lapsed on 25 January 2020. The proviso to Article 334 protected sitting Anglo-Indian nominees until the dissolution of the then-existing House or Assembly.

Can Parliament create a sub-classification within the Scheduled Castes list?

Under Article 341(2), only Parliament may include in or exclude from the SC list. In E.V. Chinnaiah v. State of A.P. (2005) the Supreme Court held that the SC list under Article 341(1) forms one homogeneous class that a State legislature cannot fragment; any sub-classification or creamy-layer demarcation among SCs must be done by Parliament. The position on sub-classification has been re-examined more recently by larger Benches; the working rule for exam purposes remains E.V. Chinnaiah, with awareness that the doctrinal field is in motion.

Is Article 16(4A) on promotional reservation a constitutional mandate?

No. Article 16(4A) is an enabling provision. The State is not bound to make reservation for SCs and STs in promotions. If the State chooses to do so, M. Nagaraj v. Union of India (2006) requires it to collect quantifiable data on inadequacy of representation in the cadre concerned and to satisfy the test of overall efficiency under Article 335. Mukesh Kumar v. State of Uttarakhand (2020) confirmed that no individual has an enforceable right to insist that the State exercise this discretion. The requirement of demonstrating SC/ST backwardness was dropped in Jarnail Singh (2018).

Can a person who migrates from one State claim Scheduled Caste status in another State?

Not for the purposes of reservation. Action Committee v. Union of India (1994) and Subhash Chandra v. Delhi SSB (2009) hold that a migrant SC/ST of one State cannot claim reservation in another State, even where a community of the same name is notified there — the entries in the Presidential Order are State-relative. But S. Pushpa v. Sivachanmugavelu (2005) clarifies that migration does not erase the underlying status; the person does not, by migration, become a member of a forward caste.

Does the proviso to Article 335 allow lowering of qualifying marks at the recruitment stage?

Read literally and as interpreted in A.P. Public Service Commission v. Baloji Badhavath (2009), the proviso to Article 335 (inserted by the 82nd Amendment, 2000) operates for the purpose of promotion. It is not a constitutional mandate at the recruitment threshold. Indra Sawhney did permit relaxation of qualifying standards in some recruitment situations consistent with administrative efficiency, but State of Karnataka v. Kumari Gowri Narayana Ambiga (1995) is clear that minimum qualifying standards may be relaxed but cannot be wholly omitted, and selection processes cannot be bypassed altogether.

What is the difference between the Article 338 and Article 338B Commissions?

Article 338 sets up the National Commission for Scheduled Castes (originally one combined Commission for SCs and STs, separated by the 89th Amendment, 2003). Article 338A then created the National Commission for Scheduled Tribes. Article 338B, inserted by the 102nd Amendment (2018), constitutionalised the National Commission for Backward Classes — previously a statutory body under the National Commission for Backward Classes Act, 1993. All three Commissions have substantively similar functions: investigating safeguards, inquiring into complaints, advising governments and reporting annually to the President.
