Scheduled Castes in India: Constitutional Safeguards for SCs and STs

Constitutional Safeguards for SCs and STs: The Five Groups

Social, Educational, Economic, Political and Administrative Safeguards

The Constitution protects these communities through safeguards of five kinds. Social safeguards remove untouchability and protect against exploitation. Educational safeguards permit special provisions, including reserved seats in admission. Economic and service safeguards promote their economic interests and permit reservation in public employment and promotion. Political safeguards reserve seats in the Lok Sabha, the State Legislative Assemblies, Panchayats and Municipalities. Administrative safeguards create institutions and give the Union a supervisory role over tribal welfare.

Scheduled Castes and Scheduled Tribes: Meaning and Identification

Articles 341 and 342: Notifying Castes and Tribes

The term "Scheduled Castes" goes back to the Government of India Act, 1935, which used it for the groups formerly known as the Depressed Classes. The Government of India (Scheduled Castes) Order, 1936, then set out the castes in a list, or Schedule, and the word "scheduled" comes from that list.

Articles 341 and 342 set out a two-stage procedure for identifying these communities. In the first stage, the President, by public notification, specifies the castes or tribes that are to be deemed Scheduled Castes or Scheduled Tribes in relation to a State or Union Territory. Where the notification concerns a State, the President acts after consultation with the Governor of that State.

In the second stage, only Parliament can change the list. Article 341(2) and Article 342(2) allow Parliament, by law, to include a community in the list or exclude it from the list; no later notification of the President can vary it.

Each list is made "in relation to" a particular State or Union Territory. A community notified as a Scheduled Tribe in one State therefore need not be a Scheduled Tribe in another. The Governor is consulted but does not declare any community a Scheduled Caste or a Scheduled Tribe.

Difference Between Scheduled Castes and Scheduled Tribes

The difference between Scheduled Castes and Scheduled Tribes lies in the basis on which each group is identified. Scheduled Castes are identified by backwardness rooted in the practice of untouchability, while Scheduled Tribes are identified by tribal characteristics such as a distinctive culture and geographical isolation. Religion also separates the two lists, and only Scheduled Tribes have special provisions for the areas where they live.

The Constitution (Scheduled Castes) Order, 1950, as amended, lists 1,108 castes across 28 States, and the Constitution (Scheduled Tribes) Order, 1950, as amended, lists 744 tribes across 22 States. The two groups are also spread differently across the country. In the 2011 Census, Scheduled Castes formed 31.94 per cent of the population of Punjab, the highest share among the States, while Arunachal Pradesh and Nagaland had no notified Scheduled Castes. Scheduled Tribes formed 94.43 per cent of the population of Mizoram and 86.48 per cent of Nagaland, while Punjab and Haryana had no notified Scheduled Tribes. In absolute numbers, Uttar Pradesh had the largest Scheduled Caste population and Madhya Pradesh the largest Scheduled Tribe population.

Inclusion and Exclusion: Lokur Committee Criteria

The Lokur Committee of 1965 laid down the criteria that are followed when a community is proposed for inclusion in, or exclusion from, the lists. For a Scheduled Caste, the test is extreme social, educational and economic backwardness arising from the practice of untouchability. For a Scheduled Tribe, the committee named five indicators:

1. Primitive traits.
2. A distinctive culture.
3. Geographical isolation.
4. Shyness of contact with the larger community.
5. Backwardness.

The scheduling process also draws on the community definitions used in the colonial census and on modern anthropological study.

Social and Educational Safeguards for SCs and STs

Article 15(4), 15(5) and Special Provisions in Education

Article 15 forbids the State to discriminate against any citizen on grounds only of religion, race, caste, sex or place of birth. Two of its clauses permit special treatment of these communities. Article 15(4), added by the Constitution (First Amendment) Act, 1951, permits the State to make any special provision for the advancement of socially and educationally backward classes or of the Scheduled Castes and the Scheduled Tribes. Reserved seats and fee concessions in public educational institutions rest on this clause.

Article 15(5), inserted by the Constitution (Ninety-third Amendment) Act, 2005, goes further. It permits special provisions, made by law, for the admission of these groups to educational institutions, including private institutions, whether aided or unaided by the State. Minority educational institutions referred to in Article 30(1) are excluded from this clause.

Both clauses belong to the right to equality in Part III, so they operate as exceptions within a Fundamental Right rather than as separate guarantees.

Article 17 and the Abolition of Untouchability

Article 17 abolishes untouchability and forbids its practice in any form. The enforcement of any disability arising out of untouchability is an offence punishable in accordance with law. Neither the Constitution nor the law defines the word. The Mysore High Court held that the word refers to the practice as it developed historically in the country, that is, the social disabilities imposed on certain classes of persons because of their birth in certain castes. The right is available against private individuals as well as the State.

Parliament has enacted two laws against untouchability and caste-based crimes. The Untouchability (Offences) Act, 1955, was comprehensively amended in 1976 and renamed the Protection of Civil Rights Act, 1955. It makes offences of acts such as preventing a person from entering a place of public worship, denying access to a shop or hotel, refusing to sell goods or render services, and preaching untouchability. A person convicted of such an offence is disqualified for election to Parliament or a State Legislature.

Because the existing laws proved inadequate against atrocities on these communities, Parliament enacted the Scheduled Castes and the Scheduled Tribes (Prevention of Atrocities) Act on 11 September 1989. It came into force on 30 January 1990 and defines atrocities against members of these communities in Section 3.

Article 46 and Protection from Social Injustice

Article 46, a Directive Principle of State Policy, directs the State to promote with special care the educational and economic interests of the weaker sections of the people, and in particular of the Scheduled Castes and the Scheduled Tribes. It also directs the State to protect them from social injustice and all forms of exploitation. Like every Directive Principle, it is not enforceable by any court, but the State has a duty to apply it in making laws.

Protection of economic resources is the clearest form this duty takes in tribal areas. In a Scheduled Area, the Governor may make regulations that prohibit or restrict the transfer of land by or among members of the Scheduled Tribes, regulate the allotment of land to them, and regulate money-lending to them. These regulations protect tribal land and tribal borrowers from exploitation.

Protective rules can also have a cost. Land that cannot be freely transferred is harder to sell or to offer as security, and reservation reaches mainly public jobs and education rather than private enterprise. The State has therefore added measures that build economic capacity. The Scheduled Castes Sub-Plan of 1979 directs benefits from the annual plans of the States and Union Territories to Scheduled Castes in at least the proportion of the Scheduled Caste population, and Stand-Up India, launched on 5 April 2016, offers bank loans between Rs 10 lakh and Rs 1 crore to Scheduled Caste, Scheduled Tribe and women entrepreneurs for a new enterprise in manufacturing, trading or services.

Economic and Service Safeguards: Reservation in Public Employment

Article 16(4), 16(4A) and Reservation in Promotion

Article 16 guarantees equality of opportunity in public employment, and Article 16(4) permits the State to reserve appointments or posts for any backward class of citizens which, in the opinion of the State, is not adequately represented in the services under the State. Scheduled Castes and Scheduled Tribes are covered by this clause. Since 1982, 15 per cent of vacancies in the public sector and in government-aided educational institutions have been reserved for Scheduled Castes and 7.5 per cent for Scheduled Tribes.

In the Indra Sawhney case of 1992, the Supreme Court held that reservation should be confined to initial appointments and should not extend to promotion, and that the total reserved quota should not exceed 50 per cent except in extraordinary situations. Parliament responded with three amendments:

1. Seventy-seventh Amendment, 1995: Inserted Article 16(4A), permitting reservation in promotion for Scheduled Castes and Scheduled Tribes not adequately represented in the services.
2. Eighty-first Amendment, 2000: Inserted Article 16(4B), so that unfilled reserved vacancies of a year can be filled in later years as a separate class, outside the 50 per cent ceiling for those years.
3. Eighty-fifth Amendment, 2001: Added "consequential seniority" to Article 16(4A), with effect from 17 June 1995.

In M. Nagaraj v. Union of India (2006), the Supreme Court upheld these amendments but treated them as enabling provisions. It held that a State wishing to reserve posts in promotion had to collect quantifiable data showing the backwardness of the class and the inadequacy of its representation, and had to keep in view overall administrative efficiency.

In Jarnail Singh v. Lachhmi Narain Gupta (2018), a five-judge bench held that the requirement to collect quantifiable data on the backwardness of the Scheduled Castes and the Scheduled Tribes was contrary to Indra Sawhney and invalid to that extent, since these groups are the most backward among the backward classes. A State must still collect quantifiable data on the inadequacy of their representation, relatable to the cadre concerned, and keep the efficiency of administration in view under Article 335.

Article 335 and the Efficiency of Administration

Article 335 states that the claims of members of the Scheduled Castes and the Scheduled Tribes shall be taken into consideration, consistently with the maintenance of efficiency of administration, in making appointments to services and posts under the Union or a State. The Article both supports these claims and limits them, since the claims must be weighed against efficiency.

The Article does not define the term "efficiency of administration". Its meaning has come from the courts, which have treated efficiency as one of the conditions that a State must satisfy before it reserves posts, especially in promotion. In this way, Article 335 acts as a limit on the reservation policies made under Article 16(4) and 16(4A).

The Constitution (Eighty-second Amendment) Act, 2000, added a proviso to Article 335. It allows the State to relax qualifying marks in an examination, or lower the standards of evaluation, for members of the Scheduled Castes and the Scheduled Tribes in matters of reservation in promotion.

Political Safeguards: Reserved Seats in Legislatures and Panchayats

Articles 330 and 332: Reserved Seats in Lok Sabha and Assemblies

Article 330 reserves seats in the Lok Sabha for the Scheduled Castes and the Scheduled Tribes, and Article 332 does the same in the Legislative Assembly of every State. The number of reserved seats in a State bears, as nearly as may be, the same proportion to the State's total seats as the State's Scheduled Caste or Scheduled Tribe population bears to its total population. Of the 543 elected seats in the Lok Sabha, 84 are reserved for Scheduled Castes and 47 for Scheduled Tribes.

The Delimitation Commission, appointed by the President, decides which constituencies are reserved. Constituencies with the highest proportion of Scheduled Tribe population are reserved for Scheduled Tribes. For Scheduled Castes, the Commission selects constituencies with a higher proportion of Scheduled Caste population but distributes them across the regions of the State, because that population is spread fairly evenly.

Reserved seats do not create separate electorates. All the voters of a reserved constituency elect its member; only the candidate must belong to the community for which the seat is reserved. A member of a Scheduled Caste or a Scheduled Tribe may also contest a general seat. For these Articles, "population" means the population at the 2001 Census until the figures of the first census taken after 2026 have been published.

Two special cases exist. Seats for the Scheduled Tribes in the autonomous districts of Assam are reserved separately, in a proportion not less than their share of the State's population. In Arunachal Pradesh, Meghalaya, Mizoram and Nagaland, Article 332(3A) sets a separate rule for reserved Scheduled Tribe seats until the seats are readjusted on the basis of the first census after 2026.

Article 334 and the Ten-Year Extensions

Article 334 fixes the period for which seats remain reserved for the Scheduled Castes and the Scheduled Tribes in the Lok Sabha and the State Assemblies. The original Constitution set this period at ten years, that is, up to 1960. Parliament has extended it by ten years at a time through seven amendments, from the Eighth Amendment of 1959 to the One Hundred and Fourth Amendment of 2019.

The One Hundred and Fourth Amendment, which came into force on 25 January 2020, made the period eighty years from the commencement of the Constitution for the Scheduled Castes and Scheduled Tribes, that is, up to 25 January 2030. It left the period for the Anglo-Indian community at seventy years, so the nomination of two Anglo-Indian members to the Lok Sabha ended in January 2020, while reservation for the Scheduled Castes and Scheduled Tribes continues.

Reservation in Panchayats and Municipalities

Articles 243D and 243T, inserted by the Seventy-third and Seventy-fourth Amendments of 1992, carry reservation down to local government. Seats are reserved for the Scheduled Castes and the Scheduled Tribes in every Panchayat and every Municipality in proportion to their share of the population of that area, and the reserved seats may be rotated among constituencies.

Three further rules apply:

• Women of these communities: Not less than one-third of the seats reserved for Scheduled Castes and Scheduled Tribes are reserved for women belonging to those communities.
• Offices of Chairpersons: The offices of Chairpersons of Panchayats at each level are reserved for Scheduled Castes and Scheduled Tribes in proportion to their population in the State; for Municipalities, the State Legislature decides the manner of reservation.
• Same end date: Reservation for the Scheduled Castes and Scheduled Tribes in these bodies, including the seats for women of those communities, ceases with the period fixed in Article 334; the general one-third reservation for women does not.

Administrative Safeguards for Scheduled Areas and Tribes

Article 339 and Union Control over Tribal Welfare

Article 339 gives the Union a supervisory role over tribal welfare in the States. Under Article 339(1), the President may at any time, and was required to at the end of ten years from the commencement of the Constitution, appoint a Commission to report on the administration of the Scheduled Areas and the welfare of the Scheduled Tribes. Under Article 339(2), the executive power of the Union extends to giving directions to a State on drawing up and carrying out schemes essential for the welfare of the Scheduled Tribes in that State.

Other administrative safeguards add to this supervision:

• Article 244 and the Fifth and Sixth Schedules: The Fifth Schedule applies to the Scheduled Areas of States other than Assam, Meghalaya, Tripura and Mizoram, and the Sixth Schedule applies to the Tribal Areas of those four States. Under the Fifth Schedule, a Tribes Advisory Council of not more than twenty members, about three-fourths of them Scheduled Tribe members of the State Assembly, advises the Governor on tribal welfare.
• Article 275(1), proviso: Grants-in-aid from the Consolidated Fund of India meet the cost of State schemes, approved by the Government of India, for the welfare of Scheduled Tribes or for raising the level of administration of Scheduled Areas.
• Article 164(1), proviso: Chhattisgarh, Jharkhand, Madhya Pradesh and Odisha must have a Minister in charge of tribal welfare, who may also look after Scheduled Castes and backward classes. The Ninety-fourth Amendment, 2006, replaced Bihar with Chhattisgarh and Jharkhand in this list.

Two constitutional commissions watch over the safeguards. The National Commission for Scheduled Castes under Article 338 and the National Commission for Scheduled Tribes under Article 338A investigate and monitor all matters relating to the safeguards, inquire into specific complaints and report to the President. Article 338A was inserted by the Eighty-ninth Amendment, 2003, which split the earlier joint commission into two.

Parliamentary Committee on the Welfare of SCs and STs

Parliament supervises the working of the safeguards through the Committee on the Welfare of Scheduled Castes and Scheduled Tribes. It has not more than 30 members: 20 elected by the Lok Sabha every year from among its members by proportional representation through the single transferable vote, and not more than 10 members of the Rajya Sabha nominated by that House to be associated with it.

The committee's composition follows three rules:

1. No Ministers: A Minister cannot be elected to the committee, and a member who becomes a Minister ceases to be a member from the date of appointment.
2. One-year term: The term of office of members does not exceed one year.
3. Chairperson chosen by the Speaker: As for other committees of the Lok Sabha, the Speaker appoints the Chairperson from among the members.

The committee considers the reports of the National Commission for Scheduled Castes and the National Commission for Scheduled Tribes and reports on the measures the Union Government should take. It examines how far the Union secures due representation of these communities in its services and posts, including those in public sector undertakings and statutory bodies, having regard to Article 335. It also reports on welfare programmes in the Union Territories.

Safeguards in Practice: Gaps and Debates

Creamy Layer and Sub-Classification of Scheduled Castes

Benefits within a reserved category have often gone to its relatively advanced communities, and two remedies are debated. Sub-classification divides a reserved category so that its most backward communities receive a share of their own. In E. V. Chinnaiah v. State of Andhra Pradesh (2004), a five-judge bench had held that the Scheduled Castes in the President's list form a single, homogeneous group that cannot be divided.

In State of Punjab v. Davinder Singh, decided on 1 August 2024, a seven-judge bench overruled Chinnaiah by a majority of 6 to 1. The Court held that States may sub-classify Scheduled Castes and Scheduled Tribes under Articles 15 and 16, because the President's power under Article 341 only identifies the communities in the list. Any sub-classification must rest on quantifiable, empirical data showing the relative backwardness of a sub-group and its inadequate representation. Justice Bela M. Trivedi dissented.

The creamy layer is the second remedy: It excludes from reservation those members of a reserved community who have come out of backwardness. For promotion, the Supreme Court had already held in Jarnail Singh (2018) that this principle, which rests on Articles 14 and 16(1), may be applied to the Scheduled Castes and Scheduled Tribes without altering the Presidential List. The community stays on the list, and only its advanced members lose the benefit of reservation.

In Davinder Singh, Justice B. R. Gavai, in his own opinion, said the State must find a way to identify a creamy layer among the Scheduled Castes and Scheduled Tribes, even if the criteria differ from those used for the Other Backward Classes. The Union government has opposed an income-based creamy layer in the Supreme Court, arguing that the concept does not apply to these groups, and petitions on the question were pending in August 2026.

Dalit Christians and Muslims: The Religion Bar in the 1950 Order

The religion bar comes from paragraph 3 of the Constitution (Scheduled Castes) Order, 1950, issued under Article 341. Only Hindus, Sikhs and Buddhists can be members of a Scheduled Caste. The Order of 1950 covered Hindus, with an exception for certain communities in Punjab who could be either Hindu or Sikh. An amendment in 1956 extended Scheduled Caste status to Dalit converts to Sikhism nationwide, and in 1990 it was extended to Buddhists, after many people turned to Buddhism at B. R. Ambedkar's call. Scheduled Tribe status, by contrast, carries no religion condition.

Dalits who have converted to Christianity or Islam therefore lose Scheduled Caste status. A petition seeking that status for Dalit Christians and Muslims was filed in the Supreme Court in 2004 and was still being heard in 2026. The Union government has defended the Order, while the National Commission for Religious and Linguistic Minorities, chaired by Justice Ranganath Misra, recommended in 2007 that paragraph 3 be deleted. That recommendation did not change the Order.

In October 2022, the Union government set up a three-member Commission of Inquiry headed by former Chief Justice of India K. G. Balakrishnan to examine whether Scheduled Caste status can be given to Dalits who converted to religions other than those named in the 1950 Order. Its last deadline expired on 10 June 2026. As of July 2026, the commission had finished its study but had not submitted its report.
