Reservation in promotion explained: Article 16(4A), and the M. Nagaraj case

The Constitution (Eighty-fifth Amendment) Act received the President's assent on 4 January 2002.¹ Its commencement clause reads:

It shall be deemed to have come into force on the 17th day of June 1995.

Six and a half years before it was signed. That is not a drafting slip, and the reason for it is most of the story of reservation in promotion.

On 16 November 1992, in Indra Sawhney, the Supreme Court held that reservation under Article 16(4) reaches the door of a government job and not the ladder inside it.¹ Within two years and seven months Parliament had written the ladder back in. It did so four times in six years, and each amendment was answering a particular judgment. In 2006 a Constitution Bench upheld all four, and attached to them a condition that none of them contains.

What the Court took away, and the runway it left

The holding was not a narrow one. It displaced a rule that had stood for three decades: in General Manager, Southern Railway v. Rangachari, the Court had held that Article 16(4) permits reservation in promotion. Indra Sawhney recorded the age of that rule and the fact that it had already survived a challenge.¹ Then it set it aside:

the majority opinion in Rangachari15, to the extent it holds, that Article 16(4) permits reservation even in the matter of promotion, is not sustainable in principle and ought to be departed from.

The Court did not stop promotions that morning. It made the ruling prospective, protecting everyone already promoted,¹ and it gave every existing arrangement a fixed runway:

wherever reservations are already provided in the matter of promotion - be it Central Services or State Services, or for that matter services under any corporation, authority or body falling under the definition of ’State’ in Article 12-such reservations shall continue in operation for a period of five years from this day.

Five years, from 16 November 1992. The first amendment arrived on 17 June 1995, two years and seven months in. Parliament legislated inside the window the Court had opened, with time still on the clock.

1995: an enabling power, and who decides

The Constitution (Seventy-seventh Amendment) Act, 1995 received assent and came into force on the same day.¹ It inserted one clause after Article 16(4):

In article 16 of the Constitution, after clause (4), the following clause shall be inserted, namely:- "(4A) Nothing in this article shall prevent the State from making any provision for reservation in matters of promotion to any class or classes of posts in the services under the State in favour of the Scheduled Castes and the Scheduled Tribes which, in the opinion of the State, are not adequately represented in the services under the State.".

Read what that does and does not do. It enables; it compels nobody. It names Scheduled Castes and Scheduled Tribes and no one else. And the test it sets is a single condition resting on four words: in the opinion of the State. As drafted in 1995, whether representation was adequate was for the government making the provision to decide.

The Statement of Objects and Reasons is where a government puts its strongest ground on the record. This one was dated 31 May 1995² and signed by Sitaram Kesri.² It gave two reasons. The first was continuity rather than desirability:

The Scheduled Castes and the Scheduled Tribes have been enjoying the facility of reservation in promotion since 1955.

The second was an outcome not met, and the conclusion drawn from it.²

Both sentences are the Government's own account of why it was acting. Neither is a finding anybody tested. That distinction sits quietly here and becomes the whole argument eleven years later.

1997: two orders, one month apart

The pressure did not come from Parliament next. It came from the Government's own filing cabinet.

Paragraph 831 of Indra Sawhney had held that relaxing qualifying marks and standards of evaluation in promotion was not permissible under Article 16(4), because of Article 335.³ Article 335 is the efficiency clause, and it is in the Constitution rather than in any judgment:

The claims of the members of the Scheduled Castes and the Scheduled Tribes shall be taken into consideration, consistently with the maintenance of efficiency of administration, in the making of appointments to services and posts in connection with the affairs of the Union or of a State

To implement that, the Department of Personnel and Training withdrew the relaxations with effect from 22 July 1997.³ A month later a second memorandum, of 29 August 1997, applied the 50 per cent limit to backlog vacancies as well as current ones, and discontinued the Special Recruitment Drive.¹

Two departmental instructions, a month apart, both tightening. What came back was paper of a different kind:

representations had been received by the Government from several quarters including the Members of Parliament. Considering the various representations, the Government has reviewed the position and decided to move for constitutional amendment with a view to restore the relaxations which were withdrawn vide instructions issued by the Department of Personnel and Training on 22.07.1997.

That sentence is the hinge of the whole decade. Relaxations removed by a departmental instruction were to be restored by amending the Constitution.

2000: the backlog leaves the year

Two amendments followed, and the bookkeeping is a trap in itself. The note that became the Eighty-first Amendment was attached to a Bill numbered ninetieth.⁵ The number on a Bill is not the number on the Act it becomes.

The Eighty-first Amendment received assent on 9 June 2000¹ and inserted clause (4B):

(4B) Nothing in this Article shall prevent the State from considering any unfilled vacancies of a year which are reserved for being filled up in that year in accordance with any provision for reservation made under clause (4) or clause (4A) as a separate class of vacancies to be filled up in any succeeding year or years and such class of vacancies shall not be considered together with the vacancies of the year in which they are being filled up for determining the ceiling of fifty per cent reservation on total number of vacancies of that year.

A reserved post nobody was appointed to in its own year now sits in its own box, outside the ceiling for the year it is finally filled in. The reason given was arithmetic, and it is the same half a percentage point that decided the previous part of this series:

As total reservations in a year for the Scheduled Castes, the Scheduled Tribes and the other Backward Classes combined together had already reached forty-nine and a half per cent and the total number of vacancies to be filled up in a year could not exceed fifty per cent.

At 49.5 per cent a year is effectively spoken for, so a backlog post has nowhere to sit inside it. Clause (4B) does not raise the ceiling. It moves things out from under it.

The Eighty-second Amendment, whose Statement of Objects and Reasons was signed by Vasundhara Raje on 22 December 1999,³ dealt with the other 1997 order by adding a proviso to Article 335 itself:

Provided that nothing in this article shall prevent in making of any provision in favour of the members of the Scheduled Castes and the Scheduled Tribes for relaxation in qualifying marks in any examination or lowering the standards of evaluation, for reservation in matters of promotion to any class or classes of services or posts in connection with the affairs of the Union or of a State

The efficiency condition stays exactly where it was. The proviso sits directly beneath it and says that condition does not prevent these particular measures in promotion.

2001: three words, backdated

The last of the four is the shortest. The entire operative change is one substitution:

In article 16 of the Constitution, in clause (4A), for the words "in matters of promotion to any class", the words "in matters of promotion, with consequential seniority, to any class" shall be substituted.

Three words, and they are not a new reservation. Accelerated promotion decides who moves up. Consequential seniority decides what the move is worth afterwards: whether the promoted officer keeps the seniority of the new grade or is re-ranked below those who were senior in the old one. Promotion is one moment; seniority is read off a list at every moment after it, including the next promotion and the one after that. The Government said as much, that the amendment was to provide consequential seniority by virtue of the rule of reservation.⁷

Then the backdating, and it is doing specific work. The amendment also negated and withdrew an Office Memorandum of 30 January 1997,⁷ which the Government's own release says had followed judgments that, in its account, had told against Scheduled Caste and Scheduled Tribe interests in government service.⁷ On the same account, the Act superseded that effect and restored the position as it stood in 1997 and before.⁷

That is the Government characterising two judgments and its own remedy, on the record, in the language of a press release. It is not a court's finding about either. What is not in dispute is the mechanism: text assented to in January 2002, operating from June 1995, reaching behind a consequence and cancelling it from a date before it arose.

The challenge, and what five judges upheld

Someone tested it. Writ Petition (Civil) No. 61 of 2002 invoked Article 32 and asked for certiorari, which quashes rather than reads down.¹ The ground was basic structure: not that the amendments were unwise, but that Parliament had damaged something it may not amend away.⁸

The petition's shape was one charge repeated. The Eighty-first Amendment was said to nullify R.K. Sabharwal,¹ the Eighty-second to nullify Indra Sawhney and the cases on efficiency,¹ and the Eighty-fifth to nullify Ajit Singh (II).¹ Those are the petitioners' allegations as the judgment records them, not findings. And the framing the Court accepted was broader than any one amendment: the issues covered all four, and action taken under them that sought to reverse the Court's own decisions on promotion, retrospectively.¹

The answer came on 19 October 2006, from five judges: Y.K. Sabharwal, K.G. Balakrishnan, S.H. Kapadia, C.K. Thakker and P.K. Balasubramanyan.¹ It was unanimous, and it has been followed since.⁸

we uphold the constitutional validity of the Constitution (Seventy-Seventh Amendment) Act, 1995, the Constitution (Eighty-First Amendment) Act, 2000, the Constitution (Eighty-Second Amendment) Act, 2000 and the Constitution (Eighty-Fifth Amendment) Act, 2001.

Every amendment in the chain, upheld in one sentence.

What upholding them did not mean

The half that is quoted less is where the Court told Parliament what its own amendments do not reach.

They do not obliterate any of the constitutional requirements, namely, ceiling-limit of 50% (quantitative limitation), the concept of creamy layer (qualitative exclusion), the sub-classification between OBC on one hand and SCs and STs on the other hand as held in Indra Sawhney5 , the concept of post-based Roster with in-built concept of replacement as held in R.K. Sabharwal8.

Four things survive the amendments: the 50 per cent ceiling, the creamy layer, the line between Other Backward Classes and the Scheduled Castes and Tribes, and the post-based roster. That roster is R.K. Sabharwal's doing, and it is a choice of denominator: the share is worked out against the posts in a cadre rather than against a year's vacancies,⁹ which keeps the reserved share fixed against the service instead of drifting with how many people happen to retire.

Then the sentence that changed how every promotion policy has to be written:

the State has to collect quantifiable data showing backwardness of the class and inadequacy of representation of that class in public employment in addition to compliance of Article 335.

Set that against 1995. The clause Parliament wrote said in the opinion of the State. The Court left the power intact and took away the opinion. Backwardness and inadequate representation now have to be counted and produced, and Article 335 has to be satisfied on top. Nagaraj's tests for when an amendment breaks the basic structure were themselves approved by nine judges in I.R. Coelho,⁸ which makes them hard to argue away.

Twenty years and two months

The file that produced all of this is small. On 1 August 1986 the Chief Controller on Northern Railway promoted some general candidates to Grade 'A' Special on an ad hoc basis; within three months they were reverted and Scheduled Caste and Scheduled Tribe candidates were promoted instead.¹

Twenty years and two months separate that reversion from the judgment on the constitutional question it raised.¹ Someone who joined service that month could have spent a working life waiting for the rule governing their own promotion to be settled.

And what settled it did not settle the argument. It converted it. Before Nagaraj the question was what a State believed about representation in its services. After Nagaraj it is what a State can show. Which leaves the question the next part is about: who actually collected the numbers, and what happened when they were produced in court.
