EWS reservation explained: the 103rd Amendment, and the 50% ceiling

Add the reservations together and the total is 59.50%.

The reservation for the new category will be in addition to the existing scheme of 15%, 7.50% and 27% resply reservations for the SC, ST and OBC-NCL, thus, bringing the total reservation to 59.50%.

Part seven of this series turned on 49.5%, half a percentage point under a ceiling of 50. This one turns on 59.5, nine and a half points over it. The ceiling did not move. On 7 November 2022 the Supreme Court held, by three votes to two, that it had never applied here in the first place.

The Chief Justice of India was in the minority.

A number that was never quite held

The ceiling is not in the Constitution. It is traced to a 1962 case about college seats in Mysore, and the most useful thing in the 2022 judgment is the passage it reproduces about what that case actually decided:

Though in the Balaji case, the Court thought that generally and in a broad way a special provision should be less than 50 per cent, and how much less than 50 per cent would depend upon the relevant prevailing circumstances in each case, the Court confessed: “In this matter again, we are reluctant to say definitely what would be a proper provision to make.” All that the Court would finally say was that in the circumstances of the case before them, a reservation of 68 per cent was inconsistent with Article 15(4) of the Constitution.

And then, in the same passage: the Court was not prepared to read Balaji as arbitrarily laying down 50 per cent as the outer limit of reservation.¹

That is worth sitting with before anything else. The ceiling everyone argues about was, on this account, a court declining to fix a number, saying 68 per cent was too much on those facts, and saying a provision should generally be less than half. It became a hard line by repetition rather than by a single holding.

Which is exactly why the challenge took the shape it did. If the rule had one clean source, counsel would have cited it. Instead he counted.

Its first real test was arithmetic rather than principle. A carry-forward rule let reserved posts unfilled in one year roll into the next, and in T. Devadasan the stacking produced a single year in which 45 vacancies were filled and 29 went to Scheduled Caste and Scheduled Tribe candidates.¹ That is 64.4%, and the rule fell. Note what tripped it: not anyone's conduct, but a total in a year. A mechanism built to protect reserved candidates crossed the line as easily as anything else could.

Then in 1992 the ceiling was approved by nine judges in Indra Sawhney, and the same judgment closed a second door:

The economic criterion alone for determining backwardness of classes or groups is impermissible, because the indicators are social and educational backwardness having regard to the express terms of Articles 15(4) and 16(4)

Hold those two together, because the 103rd Amendment runs straight at both. A quota built on economic criteria alone, sitting above 50%.

The doors that were already open

The wall was never solid, which matters for what happened next.

Tamil Nadu has reserved 69% since 1993, under an Act placed in the Ninth Schedule.² Counsel put that to the Court as the single exception: the ceiling cannot be breached in any circumstance except where a law is sheltered there.¹ It is worth knowing what that shelter mostly holds. Of 284 entries in the Ninth Schedule, 263 are land reform and agrarian legislation.¹

There was a second way round, and it is a definitional one. The 50% rule applies to reservations proper, meaning a block of posts set aside before the competition starts, and not to exemptions or concessions.¹ Structure a benefit as a relaxation in how someone competes and the ceiling is never counted against it. The wall does not come down; the measure simply never walks into the room.

Remember that shape. It is the shape of the judgment.

Eleven days

The amendment moved fast. The Bill was introduced in the Lok Sabha on 8 January 2019 and passed there the next day.¹ It received the President's assent on 12 January and was published in the Gazette the same day,¹ then came into effect on 14 January.¹

Parliament's own account of why is short and is worth reading as written. Economically weaker sections of citizens were not eligible for the benefit of reservation,¹ and had largely remained excluded from higher education and public employment because of their financial incapacity to compete with economically more privileged persons.¹

Eleven days after it commenced, the Supreme Court issued notice on a petition challenging it.² A three-judge Bench referred the matter to a Constitution Bench on 5 August 2020,¹ and the questions were formulated on 8 September 2022 — among them whether the 50% cap is part of the basic structure, and whether a reservation structured singularly on economic criteria violates it.¹

A count, against a concession

The challenge rested on repetition. Senior counsel Gopal Sankaranarayanan did not argue that the ceiling was self-evident; he counted it. He told the Court the words in addition to the existing reservation breach the ceiling, and pointed to more than 54 judgments of the Court, across more than 60 years, saying the same thing.¹ His remedy was surgical: sever those words and leave the rest of the amendment standing.¹

The Union did not deny the line. It moved it sideways. In its counter affidavit it pleaded that the 50% limit applies to reservations under Articles 15(4), 15(5) and 16(4), and not to Article 15(6).¹ And the Attorney General argued the rule was never absolute:

the fifty per cent. limit is not a sacrosanct rule

That argument draws its force from the ceiling's own wording. Indra Sawhney had allowed that extraordinary situations might warrant limited relaxation, so on this reading the exception proves the rule was never inviolable, and therefore never basic structure.

These are submissions on the record, not findings. But notice that both sides had already accepted the same premise: the fight was about whether the new quota was inside the room, not about whether the room had walls.

What three judges held

On 7 November 2022 five judges delivered four separate judgments, and the Court's own order records how they divided:

In view of the decision rendered by the majority consisting of Hon’ble Mr. Justice Dinesh Maheshwari, Hon’ble Ms. Justice Bela M. Trivedi and Hon’ble Mr. Justice J.B. Pardiwala, the challenge raised to 103 rd Amendment to the Constitution fails and the decision rendered by Hon’ble Mr. Justice S. Ravindra Bhat remains in minority.

Justice Bhat wrote for himself and for the Chief Justice,¹ so the order upholding the amendment is signed first by a Chief Justice who did not agree with it.

The holding gives two reasons, and the second is the quieter and the more consequential:

that ceiling limit itself is not inflexible and in any case, applies only to the reservations envisaged by Articles 15(4), 15(5) and 16(4) of the Constitution of India

Read that as two separate answers to the same question. The first says the wall can be moved. The second says the wall was somewhere else all along — EWS reservation comes from clause (6), and the ceiling was written for clauses (4) and (5). On the second reasoning nothing was breached, because nothing was crossed.

That is the concessions move from earlier in this piece, applied at constitutional scale. The measure never walks into the room.

The petitions were dismissed.¹

What two judges said would follow

Justice Bhat would have struck down the two sections that inserted the clauses:

are unconstitutional and void on the ground that they destroyed and are violative of the basic structure of the Constitution

Then the dissent does something unexpected. On the question the whole case appeared to be about, it declines to rule: it finds no need for a specific finding on whether breaching the 50% cap violates the basic structure.¹ What it does instead is describe the architecture the majority had accepted — the existing 50% left where it is, and a new category placed on top of it — and warn about the shape of that:

permitting the breach of the 50% rule as it were through this reasoning, becomes a gateway for further infractions

A gateway, not a door. A door opens once for one thing. A gateway is a route, and a route stays open for whoever comes next with a reason that looks close enough.

What is standing

The ceiling is intact and it is smaller than it was. It still governs reservations under Articles 15(4), 15(5) and 16(4), which is where reservation for Scheduled Castes, Scheduled Tribes and Other Backward Classes lives. It does not reach clause (6). So a total of 59.50% is both above 50% and, on the majority's reasoning, not a breach of it.

Set that against where this series began. The Poona Pact gave reserved seats a ten-year clock. The Constituent Assembly wrote another. Indra Sawhney fixed a ceiling and refused a 10% quota on economic criteria in the same judgment. Thirty years later a 10% quota on economic criteria was upheld, and the ceiling survived by being held not to apply.

Nothing here was struck down, and nothing was formally moved. What changed is which room the wall is in.
