Indra Sawhney case explained: the 50% ceiling, and the creamy layer

The memorandum reserved 27% of posts for backward classes. ¹

Half a percentage point under 50. Everything nine judges decided on 16 November 1992 sits in that gap, and so does most of what has been argued since.

What was actually on trial

Two documents. The Office Memorandum of 13 August 1990, and the amended one of 25 September 1991 that reiterated it and added a 10% reservation for other economically backward sections.¹

Not the Mandal report. A five-judge Bench had said so in its order of 8 August 1991: the validity of the Commission's report as such was not in issue.¹

That distinction is easy to lose and it matters. The Court was asked whether two executive orders were constitutional, not whether 3,743 was the right number of castes. It held that the provision contemplated by Article 16(4) can be made by the executive wing, and that the memoranda were executive orders under Article 73.¹

Where the 50% line came from

The ceiling everyone treats as constitutional text is judicial. The judgment records that Balaji fixed the maximum at not exceeding 50%,¹ and that in Thomas Fazal Ali J observed that the decided cases laid down that reservation should not exceed 50% while describing this as a rule of caution rather than of law.¹

So the line arrived as caution, hardened through repetition, and in 1992 became a holding: reservations under Article 16(4) should not exceed 50%.¹ Reservation, being an extreme form of protective measure, should be confined to a minority of available posts.¹

The Court allowed one narrow relaxation, for far-flung and remote areas.¹ And it changed the arithmetic that had defeated the rule before:

we hold that for the purpose of applying the rule of 50% an year should be taken as the unit and not the entire strength of the cadre, service or the unit, as the case may be.

That single sentence is the answer to Devadasan, where carry-forward turned a 17.5% quota into a 65% year. Measure by year and the third-year spike is the breach. Devadasan was overruled to the extent it was inconsistent.¹

The judges who would not sign the ceiling

The ceiling was not unanimous. One judge writing separately said he was unable to agree with fixing 50% as the maximum limit for socially and educationally backward classes.¹ Justice P. B. Sawant held there was no legal infirmity in reservations exceeding it in appropriate cases.¹

A number that is argued about for 30 years afterwards did not command the bench that imposed it. That is worth knowing before anyone calls it settled.

What the arguments looked like

The case drew the era's constitutional bar, and the positions did not line up neatly.

Sri N. A. Palkhiwala argued that reserving half the posts would seriously jeopardise efficiency.¹ Sri K. K. Venugopal argued that an economic criterion must be applied both in determining backward classes and in excluding sections from them.¹ Sri Ram Jethmalani, for Bihar, argued that backward classes in Article 16(4) meant only the Shudra castes.¹

Those are submissions recorded in the judgment, not findings. They are what counsel put, and the Court accepted some and refused others.

One of them carried a fact that decided a later question. Counsel for Tamil Nadu submitted that the State had already tried an income limit and given it up:

at one stage (in July 1979) the State of Tamil Nadu did indeed prescribe such an income limit but had to delete it in view of the practical difficulties encountered and also in view of the representation received.

A state had tried a means test and abandoned it. The Court was about to order one for the whole country.

What lived and what died

The judgment upheld the 13 August 1990 memorandum, subject to exclusion of socially advanced members.¹

The 1991 memorandum fared worse. Its paragraph dividing backward classes into poorer and other sections was read down: the word preference was construed so the clause could survive as equitable apportionment rather than a sub-quota.¹ And the 10% for other economically backward sections was struck down outright.¹

The reasoning is a sentence long:

No reservation can be made on economic criteria.

With the structural holding beside it: ¹

Article 16(4) is the only door. That is the holding the 103rd Amendment would eventually be written against, 27 years later.

Promotions, with a five-year fuse

The Court held that Article 16(4) does not permit reservation in the matter of promotion, disagreeing with the earlier Rangachari view.¹

Then it declined to apply that immediately. ¹ And existing promotion reservations in Central Services, State Services and bodies under Article 12 ¹

A constitutional bar with a five-year runway. That runway is why the next 30 years of this story exist: Parliament used it, and the amendments that followed are a separate argument.

Inventing the creamy layer

The most consequential two words in the judgment are not in the Constitution.

'Creamy layer' can be, and must be excluded.

¹

Note the shape of it. A judgment that had just held no reservation can be made on economic criteria ordered an economic criterion for taking people out. Income decides exclusion where it may not decide inclusion, which is a distinction the Court drew deliberately and which has been litigated ever since.

And it came with a safeguard against immediate disruption:

No section of the SEBCs can be excluded on the ground of creamy layer till the Government - Central and State - takes a decision in this regard on a review on the recommendations of a Commission or a Committee to be appointed by the Government.

Four months

The Court did not leave implementation to goodwill. It set a deadline twice.

Within four months from today the Government of India shall specify the bases, applying the relevant and requisite socio-economic criteria to exclude socially advanced persons/sections ('creamy layer') from 'Other Backward Classes'.

And on the machinery for disputed lists:

The Government of India, each of the State Governments and the Administrations of Union Territories shall, within four months from today, constitute a permanent body for entertaining, examining and recommending upon requests for inclusion and complaints of over-inclusion and under-inclusion in the lists of other backward classes of citizens.

The reason for that second direction is in the record the judgment recites. Karnataka's list had communities struck down by its High Court; Madhya Pradesh's list, based on the Mahajan Commission report of December 1983, was stayed; Uttar Pradesh's was under challenge in the Supreme Court; Goa's was too.¹

Four states, four contested lists. A permanent body was the answer to a problem the Court could see repeating.

The machinery it built

The deadlines were met. The Government of India set up an Expert Committee by Resolution of 22 February 1993 to determine the creamy layer criteria.²

Parliament passed the National Commission for Backward Classes Act, 1993, Act No. 27 of 1993, which received assent on 2 April 1993 and was deemed to have come into force on 1 February 1993.² The Commission itself was constituted on 14 August 1993, with Justice R. N. Prasad as chairperson.²

The Act's design carries the judgment's anxieties. The Chairperson is or has been a judge of the Supreme Court or a High Court.² Members hold office for three years.² The Central Government must revise the lists after ten years.² And the Commission's advice is ordinarily binding on the Central Government.²

Ordinarily binding is an unusual phrase for an advisory body, and it is the load-bearing word in the Act.

The line that keeps moving

The creamy layer was given a number, and the number has not stayed still.

Under the original 1993 order the threshold was a gross annual income of Rs 1 lakh or above for three consecutive years.² It was raised to Rs 2.5 lakh,² then to Rs 4.5 lakh with effect from 3 October 2008.² The Commission recommended further increases in reports of 23 January 2004 and 14 September 2011.²

An exclusion defined by a rupee figure has to be re-set as money loses value, and each re-setting is a decision about how many people leave the category. The test the Court ordered to make reservation self-limiting requires a political act to stay where it was put.

Half a percent, thirty years on

What the machinery has done is countable. The Commission has tendered 1,317 advices on inclusion or rejection in the Central List.² The lists themselves stand at 2,342 entries centrally and 2,449 across the States.²

Those entries are castes, communities, sub-castes and synonyms rather than distinct groups, so the number counts rows in a register and not populations.

Set that against where this began. A commission scored castes on 11 indicators out of 22 and found 52% of India. A government converted that into 27% because 27% was what a judicial estimate left available. Nine judges then upheld the 27%, refused the 10% beside it, fixed the ceiling at 50% over the objection of some of their own number, ordered an income test for exclusion in the same breath as holding that economics cannot decide inclusion, and gave promotions a five-year fuse.

Half a percentage point of room, and a register of nearly 4,800 entries built inside it.
