A note that says the department has a backlog of forty SC posts may be right, or it may have confused two figures that the rules treat quite differently. The distinction is not pedantic — it determines whether the vacancies can be filled outside the fifty per cent ceiling for the year, and whether they lapse.

The two figures

Shortfall is a stock measure read off the roster: the number of posts a category is entitled to under the roster, less the number of persons of that category actually holding those posts. It tells you where the cadre stands today.

Backlog is narrower: reserved vacancies that were earmarked in earlier recruitment years, went unfilled for want of suitable candidates, and are still vacant. It tells you what was not filled when it should have been.

Backlog is a subset of shortfall. A cadre can have a shortfall with no backlog at all — for instance where the roster entitlement rose because the sanctioned strength was increased and the recruitment to match has not yet happened. Only backlog attracts the special treatment under Article 16(4B).

Article 16(4B)

Inserted by the Constitution (Eighty-first Amendment) Act, 2000, Article 16(4B) permits unfilled reserved vacancies of a year to be considered as a separate class of vacancies to be filled up in any succeeding year or years, and provides that they 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.

The implementing instruction is Office Memorandum No. 36012/5/97-Estt.(Res.)(Vol.II) dated 20 July 2000, reinforced by Office Memorandum No. 36033/1/2008-Estt.(Res.) dated 15 July 2008.

This is what makes a special recruitment drive for backlog vacancies possible. Without it, a department with a large backlog could only fill reserved vacancies up to fifty per cent of the current year's total, which in a year of few vacancies would make the backlog essentially unclearable.

What the operative rules are

The three-year rule and where it actually belongs

The most persistent error in this area is the belief that backlog reserved vacancies lapse after three years. They do not.

The three-year carry-forward belongs to the single-vacancy rule, which is a different rule for a different situation. Where only one vacancy arises in a recruitment year and the roster point falling due is reserved for SC or ST, the post is treated as unreserved and filled accordingly, and the reservation is carried forward to the next three recruitment years, ignoring years in which no vacancy arose. That is Office Memorandum No. 1/9/74-Estt.(SCT) dated 29 April 1975, restated in 2003.

Backlog under Article 16(4B) has no time limit. Attaching the three-year rule to it, as blogs and even some internal notes do, produces the conclusion that a backlog can be written off by waiting — which is the opposite of what the amendment was enacted to achieve.

Computing the figures correctly

Three things need to be right before a shortfall figure means anything.

The roster must be current. If the sanctioned strength has changed and the roster has not been recast, the entitlement figure is wrong and so is everything derived from it. Own-merit appointees must be excluded from the count of reserved posts filled. Part 10 works through why, and what the error costs. This single adjustment is the commonest reason a reported shortfall is too low. Direct recruitment and promotion must be counted separately, because they run on separate rosters with different categories. A combined figure is only meaningful for the specific purpose of deciding whether a backlog has lapsed, where the test is the combined representation of the category across both.

What to put in the note

When a section reports the reservation position of a cadre, the useful note separates the figures rather than merging them: the sanctioned strength and the date the roster was last recast; the entitlement of each category under the roster; the number of posts of each category actually filled, excluding own-merit appointees; the resulting shortfall; and, separately, how much of that shortfall is backlog from identified earlier years.

A note in that form can be acted on. A note that reports a single backlog figure usually cannot, because the reader cannot tell whether the fifty per cent relaxation under Article 16(4B) applies to it.

Frequently Asked Questions (FAQ)

Q1. Do backlog reserved vacancies lapse after three years?

No. Backlog vacancies under Article 16(4B) are treated as a separate class and lapse only when the combined representation of the category in the cadre reaches the prescribed number of reserved posts. The three-year carry-forward belongs to the single-vacancy rule, which is a different rule for the situation where only one vacancy arises in a year.

Q2. What is the difference between shortfall and backlog?

Shortfall is the gap between what the roster entitles a category to and what it actually holds now. Backlog is the narrower figure of reserved vacancies earmarked in earlier years that went unfilled and are still vacant. Backlog is a subset of shortfall, and only backlog escapes the fifty per cent ceiling for the year in which it is filled.

Q3. Can we exceed fifty per cent reservation in a year to clear backlog?

Yes, to the extent of the backlog. Article 16(4B) provides that backlog vacancies are not counted together with the current year's vacancies for the purpose of the fifty per cent ceiling. The ceiling continues to apply to the current year's vacancies.

Q4. Why is our shortfall figure lower than it should be?

The commonest cause is counting own-merit appointees against the reserved quota. A reserved-category candidate appointed on the general standard without any relaxation occupies an unreserved post, so the reserved points remain unfilled and the shortfall is correspondingly larger than the register suggests.
