The Constitution guarantees “equality before the law” and “equal protection of the laws” under Article 14. The principle of equal protection does not mean that every person must invariably be treated identically. It permits reasonable classification: persons who are similarly situated should be treated alike, while persons differently situated may be treated differently where there is a constitutionally valid basis for such differentiation.
“Equal protection” is therefore a guarantee of equal treatment of persons in equal circumstances, while permitting differentiation where circumstances are genuinely different.
This distinction lies at the heart of India's constitutional approach to social justice.
The Constitution, adopted in 1950, established equality as a fundamental principle while simultaneously recognising that historical and social disadvantages could require affirmative measures. Article 15 prohibited discrimination on specified grounds, while Article 16 guaranteed equality of opportunity in public employment. Article 16(4), as part of the original Constitution, enabled the State to make provision for the reservation of appointments or posts in favour of a backward class of citizens that, in the State's opinion, was not adequately represented in public services.
The First Constitutional Amendment of 1951 subsequently inserted Article 15(4), expressly enabling the State to make special provisions for the advancement of socially and educationally backward classes and for Scheduled Castes and Scheduled Tribes.
Thus, the Constitution did not treat equality and affirmative action as contradictory. It sought to reconcile them.
The question before India today is whether the architecture that has evolved over the decades continues to provide the most equitable way of achieving that constitutional promise.
From social justice to a wider conception of disadvantage
Reservation was conceived as an instrument to address historical exclusion and unequal access to opportunity. That objective remains constitutionally important.
But Indian society has changed substantially since 1950.
Economic deprivation, educational disadvantage and lack of opportunity today cut across social categories. At the same time, caste remains a social reality and historical discrimination has not disappeared.
The challenge, therefore, is not to deny historical disadvantage. It is to ask whether a system designed over different stages of India's constitutional development should now be examined afresh in the light of social mobility, economic change and the continuing aspiration for equal opportunity.
The Constitution itself has evolved in response to these changing realities.
The 77th Constitutional Amendment of 1995 inserted Article 16(4A), enabling reservation in promotions for Scheduled Castes and Scheduled Tribes where the constitutional conditions were satisfied.
The 81st Amendment of 2000 inserted Article 16(4B), dealing with unfilled reserved vacancies carried forward from earlier years.
The 82nd Amendment of 2000 amended Article 335 to permit provisions for relaxation in qualifying marks or lowering standards of evaluation in examinations or in matters relating to reservation in promotion for SCs and STs.
The 93rd Amendment of 2005 inserted Article 15(5), enabling special provisions for the advancement of socially and educationally backward classes and SCs and STs in admissions to educational institutions, including private educational institutions, subject to the constitutional provision.
And then came a significant development in the direction of economic disadvantage.
On 7 January 2019, the Union Cabinet approved the proposal that ultimately became the Constitution (One Hundred and Third Amendment) Act, 2019. The amendment inserted Articles 15(6) and 16(6), enabling special provisions, including reservation, for Economically Weaker Sections (EWS) outside the classes already covered by Articles 15(4), 15(5) and 16(4).
The EWS framework therefore represented an important constitutional recognition that economic disadvantage could itself constitute a basis for affirmative action.
In November 2022, the Supreme Court, in Janhit Abhiyan v. Union of India, upheld the constitutional validity of the 103rd Amendment and the 10% EWS reservation. (Sci API)
That development deserves much greater attention in the national debate.
The question of equal protection
If equal protection permits differentiation between persons who are genuinely differently situated, the larger question is this:
How should India determine disadvantage in a society that has undergone enormous social and economic change?
Can a constitutional commitment to social justice accommodate a framework in which economic deprivation receives a substantially greater role?
Can the benefits of affirmative action be designed in a manner that reaches those who genuinely need assistance while also encouraging social mobility?
And can we build a system in which children born into poverty, irrespective of caste, are not denied opportunity simply because their disadvantage does not fit neatly into an inherited classification?
These are not questions against social justice.
They are questions about how social justice should evolve.
The creamy-layer question and social mobility
The Supreme Court's decision in Indra Sawhney v. Union of India in 1992 remains a landmark in the constitutional history of reservation.
Among other things, the judgment recognised the principle of excluding the “creamy layer” among OBCs from reservation benefits. The underlying idea was significant: if affirmative action is intended to assist the genuinely disadvantaged, those who have already achieved a substantial degree of social and economic advancement should not indefinitely receive the same benefit.
The principle of social mobility therefore cannot be ignored.
The question becomes even more complicated when the distinction between different sections within reserved categories is examined.
If a family has achieved substantial educational, professional and economic advancement, should its children continue to receive exactly the same reservation benefit as children from families that remain deeply disadvantaged?
That question deserves a serious, evidence-based national discussion.
At the same time, any reform must recognise the constitutional and social realities surrounding SCs and STs and cannot simply assume that economic advancement by itself erases every form of historical discrimination.
That is precisely why the debate needs to move beyond slogans.
Reservation and the 50 per cent principle
The Supreme Court in Indra Sawhney established 50 per cent as the general ceiling for reservation while recognising that extraordinary circumstances could justify departure from that principle. The Court also emphasised that such departures required exceptional justification. (Sci API)
This principle has subsequently been at the centre of several constitutional disputes.
On 5 May 2021, the Supreme Court struck down the Maharashtra legislation providing reservation to the Maratha community beyond the 50 per cent ceiling, holding that the circumstances relied upon by the State did not justify such an extraordinary departure. The Court emphasised the exceptional nature of any departure from the ceiling. (Sci API)
At the same time, the Supreme Court's 2022 EWS judgment clarified that the 10 per cent EWS reservation created by the 103rd Amendment operated as a distinct constitutional provision and was not simply an extension of the reservation categories covered by Articles 15(4), 15(5) and 16(4). (Sci API)
The jurisprudence is therefore more nuanced than a simple assertion that all reservations can never cross 50 per cent.
That nuance must be preserved in any serious reform debate.
Reservation in promotions
The question of reservation in promotions also illustrates how the constitutional framework has evolved.
In Indra Sawhney, the Supreme Court held that Article 16(4), as it then stood, did not permit reservation in promotions. Parliament subsequently enacted the 77th Constitutional Amendment in 1995, inserting Article 16(4A) to enable reservation in promotion for SCs and STs subject to constitutional requirements.
The 81st Amendment subsequently dealt with backlog vacancies through Article 16(4B).
The 82nd Amendment modified Article 335 by enabling relaxation in qualifying marks and standards of evaluation in specified circumstances relating to SCs and STs.
These amendments demonstrate that India's reservation architecture has never been static. Parliament and the courts have continuously responded to changing circumstances.
That is precisely why it is legitimate to ask whether further reform is now required.
The larger paradox
There is a larger paradox that India cannot continue to avoid.
On one side are citizens who remain victims of historical social disadvantage and for whom affirmative action continues to have genuine importance.
On the other are economically deprived citizens outside the reserved categories who compete for a limited number of educational seats and public employment opportunities.
The constitutional recognition of EWS has already acknowledged that economic disadvantage deserves consideration.
The next question is whether India should move towards a more comprehensive conception of disadvantage in which economic deprivation, educational deprivation, social disadvantage and historical exclusion are all considered through a transparent and evidence-based framework.
Such a system would not necessarily mean abandoning affirmative action.
It could mean making affirmative action more precisely targeted.
Social justice must also recognise social mobility
A society cannot remain permanently frozen into categories.
If affirmative action is intended to create opportunity, then the success of that policy should ultimately be measured by whether it enables families and communities to move forward.
The objective cannot be to preserve categories indefinitely.
The objective must be to ensure that disadvantage does not become hereditary.
That is why the principle of social mobility deserves to become a central part of India's reservation debate.
A child born into poverty should have the opportunity to rise regardless of caste.
A child belonging to a historically disadvantaged community should not be denied the constitutional protection intended to address that historical disadvantage.
And a child from a family that has already achieved substantial social and economic advancement should not automatically be assumed to remain equally disadvantaged.
A modern system must be capable of recognising all three realities.
The constitutional promise
Article 335 originally required that the claims of SCs and STs be considered consistently with the maintenance of administrative efficiency.
The 82nd Amendment subsequently added a proviso permitting specified relaxations and concessions for SCs and STs.
The constitutional journey therefore reveals an ongoing attempt to reconcile two important objectives:
social justice and equality of opportunity on the one hand, and institutional efficiency and fairness on the other.
Neither objective can simply be dismissed.
India needs both.
What should the next reform look like?
The debate should now move beyond the question of whether reservation is good or bad.
That is too simplistic.
The real questions are:
Who is disadvantaged?
How should disadvantage be measured?
How long should a particular benefit continue?
How can social mobility be recognised?
How can the genuinely deprived receive priority?
How can affirmative action coexist with merit and institutional efficiency?
And, most importantly:
How can India progressively move towards a society in which reservation becomes less necessary because equal opportunity has become more of a reality?
These questions require constitutional maturity rather than political opportunism.
A national conversation is overdue
India's political parties have often treated caste classifications as instruments of electoral mobilisation.
That has made an already difficult subject even more difficult.
Citizens should not be reduced to vote banks.
Nor should any community be asked to surrender legitimate constitutional protections merely because the political discourse has become polarised.
The way forward is a national conversation based on evidence, constitutional principles and measurable outcomes.
The Constitution itself provides the mechanism for such evolution: Parliament can amend the Constitution when the democratic mandate exists, subject of course to the constitutional limitations recognised by the Supreme Court.
“We, the people” therefore have a responsibility to participate in this debate.
The objective should not be to pit one caste against another, or one category against another.
It should be to build a system in which economic deprivation, educational disadvantage, historical exclusion and genuine social disadvantage are addressed fairly and transparently.
From categories to opportunity
India has travelled a long distance since 1950.
The reservation system has evolved through constitutional amendments, legislation and judicial decisions. The introduction of EWS reservation demonstrated that the Constitution can recognise economic disadvantage alongside other forms of disadvantage.
The next stage should be an honest examination of whether the existing framework is delivering the maximum possible social justice.
The answer cannot be found in the politics of permanent categorisation.
It must be found in equal opportunity, social mobility and genuine empowerment.
We should seek a system in which every child—whether born into a historically disadvantaged community or an economically deprived family outside the existing reservation framework—has a fair chance to compete, learn, work and rise.
That is not a rejection of social justice.
It is an attempt to make social justice more inclusive.
The people of India should therefore remain vigilant against political parties that treat communities merely as vote banks. They should demand from their representatives a clear commitment to opportunity, education, employment, economic mobility and institutional fairness.
The ultimate goal should be a society in which caste no longer determines a person's prospects, poverty no longer determines a child's destiny, and affirmative action becomes a bridge to equality rather than a permanent architecture of social division.
India must not be trapped forever by the categories of the past.
We must build a future in which equal protection of the law means, above all, equal dignity, equal opportunity and a genuine chance to rise.
That is the social justice that India should aspire to.
