For armed forces personnel, paramilitary forces and government employees, the difference between a cadre post and a posting held on deputation often decides critical questions of promotion, seniority, lien and absorption. This article explains the core principles that govern cadre posts when they are manned on deputation, the rights and the limits of a deputationist, and the key Supreme Court and High Court rulings that settle the position.
What is a cadre post?
A cadre post is a post sanctioned as part of a particular service or cadre. A deputationist occupying the post does not change the nature of the post. If a person is brought on deputation to a cadre post, the post remains a cadre post deputation is only a temporary mode of manning.
No vested right to continue on deputation or to be absorbed
There is no vested right to continue on deputation and no right to absorption unless a rule expressly grants it. The Supreme Court has repeatedly held that a deputationist can be repatriated at any time, and has no vested right to continue or to be absorbed, unless there is a statutory rule, regulation or order having the force of law that grants such a right.
Key Supreme Court and High Court rulings
- Ratilal B. Soni v. State of Gujarat, (1990) Supp SCC 243 — the Supreme Court held that a deputationist can be reverted to the parent cadre at any time, with no right to be absorbed on the deputation post.
- Kunal Nanda v. Union of India, (2000) 5 SCC 362 — unless supported by a rule having the force of law, a deputationist cannot claim absorption, and has no vested right to continue on deputation.
- State of Punjab v. Inder Singh, (1997) 8 SCC 372 — the Supreme Court reiterated the settled position on deputation, reversion and related consequences.
- Monu Sharma v. Union of India, W.P.(C) 19132/2025, Delhi High Court (22 December 2025) — held that the law that a deputationist has no right to continue till the expiry of the deputation period is “set in stone”; the Court will interfere only if the rules bar premature repatriation, or if mala fides or similar grounds are shown.
- Delhi High Court (20 November 2024) — reiterated that deputationists do not have an inherent right of absorption; and where cadre posts are abolished by a cadre review, there can be no claim to be absorbed into posts that no longer exist.
Effect of deputation on a cadre post
Situation 1: A cadre officer goes out on deputation
- Lien: generally, the officer retains a lien in the parent cadre, unless the rules provide otherwise.
- Promotion in the parent cadre while on deputation: in many services, an officer can be considered for promotion in the parent cadre while on deputation, subject to eligibility, vigilance clearance and DPC rules. If promoted, the promotion may be treated as notional until the officer joins, or the officer may be asked to revert and return to take up the promoted post, depending on the rules.
- Vacancy management: the cadre post the officer vacated may be filled by another cadre officer, by someone on deputation, or through an ad-hoc arrangement, depending on the vacancy rules.
Situation 2: A non-cadre person is brought on deputation to a cadre post
- It does not convert the post into a non-cadre post, it remains a cadre post.
- It should not block cadre promotions beyond what the rules permit.
- If deputation is allowed only when no suitable cadre officer is available, then continued deputation despite such availability can be challenged.
- Tenure is limited, deputation is normally time-bound, and overstaying can be questioned.
- Seniority: a deputationist does not become part of the cadre seniority merely by occupying a cadre post, unless absorbed as per the rules.
Situation 3: A cadre post is kept “encumbered” while the officer is on deputation
This means the post is treated as “held” for staffing calculations. Its effects are:
- It may temporarily reduce “effective vacancies” for promotions, depending on the cadre and vacancy-calculation rules.
- Many disputes arise when departments keep a post encumbered and simultaneously fill it, affecting vacancy-based promotions.
Typical legal and service disputes that arise
- A deputationist continuing on a cadre post even though cadre officers are available.
- A cadre vacancy that should be counted for promotion, but which the department says is not available due to deputation or encumbrance.
- An officer on deputation denied consideration for promotion in the parent cadre.
- A cadre post treated as ex-cadre or temporary without authority.
Frequently asked questions
Does a deputationist have a right to be absorbed into a cadre post?
No. Courts have held that a deputationist has no vested right to absorption unless a statutory rule, regulation or order having the force of law grants it (as in Kunal Nanda v. Union of India, (2000) 5 SCC 362, and Ratilal B. Soni v. State of Gujarat, (1990) Supp SCC 243).
Can a deputationist be repatriated before the deputation tenure ends?
Yes. The Supreme Court has held that a deputationist can be repatriated at any time and has no vested right to continue. The Delhi High Court in Monu Sharma v. Union of India (22 December 2025) described this position as “set in stone”, subject to the rules barring premature repatriation or proof of mala fides.
Does bringing a deputationist into a cadre post change its character?
No. The post remains a cadre post — deputation is only a temporary mode of manning and does not convert it into a non-cadre post.
Does a deputationist acquire cadre seniority?
No. A deputationist does not become part of the cadre seniority merely by occupying a cadre post, unless absorbed in accordance with the rules.
