Case Laws & Commentary - Income-tax Act, 1961 (as amended by the Finance Act, 2026) - bharattax.co Treatise
Provision: Section 129 - on a change of incumbent, the succeeding authority may continue a proceeding from the stage at which it was left; proviso: the assessee may demand that the previous proceeding or any part be reopened, or that before any order is passed he be reheard.
Chapter / Part: Chapter XIII, Part B - Jurisdiction.
FA 2026 status: Not amended by the Finance Act, 2026.
Nature: Continuity-of-proceedings provision carrying an important natural-justice proviso (right to demand rehearing).
A. SECTION COMMENTARY
Continuity, and the assessee's right to be reheard
Section 129 secures administrative continuity: when the officer seized of a proceeding is replaced - by transfer, retirement or otherwise - his successor may carry on from the stage at which the matter stood, without starting afresh. This avoids the proceeding collapsing every time personnel change. But the section balances continuity with fairness through its proviso, which gives the assessee two valuable rights: (i) to demand that the previous proceeding, or any part of it, be reopened; and (ii) to demand that, before any order is passed against him, he be reheard by the successor. The successor who has not himself heard the assessee's evidence and arguments may not, over the assessee's objection, simply decide on the strength of the predecessor's record.
The right must be claimed; it is not automatic
The proviso confers a right to demand a rehearing; it does not require the successor to rehear in every case suo motu. If the assessee does not exercise the right, the successor may proceed on the existing record and the resulting order is unimpeachable on this ground. Where, however, the assessee does demand a rehearing and is denied one, the order is liable to be set aside for breach of the statutory safeguard, which is a particularised form of the natural-justice principle that he who decides must hear. The practitioner should therefore make the demand for rehearing in writing and on the record whenever an order is likely to issue from an officer who has not heard the matter.
Scope and limits
Section 129 applies to the continuation of an existing proceeding on a change of the officer holding the same office; it is not a vehicle for reopening concluded assessments, nor does it dispense with the separate requirements of jurisdiction. The de facto officer doctrine independently protects acts done by the predecessor. Read together, section 129 (continuity), section 124 (jurisdiction) and the natural-justice proviso furnish a coherent answer to the practical disruption caused by frequent transfers within the Department.
B. STATUTORY POSITION (verbatim text)
Reproduced below is section 129 as it stands in the bare Act.
129. Whenever in respect of any proceeding under this Act an income-tax authority ceases to exercise jurisdiction and is succeeded by another who has and exercises jurisdiction, the income-tax authority so succeeding may continue the proceeding from the stage at which the proceeding was left by his predecessor:
Provided that the assessee concerned may demand that before the proceeding is so continued the previous proceeding or any part thereof be reopened or that before any order of assessment is passed against him, he be reheard.
Note: Direct authority squarely on section 129 is limited. The proviso is an embodiment of the natural-justice rule that the authority who decides must hear; the cognate authorities below supply that controlling principle.
C. AUTHORITIES
Cluster 1 - He who decides must hear; the right to demand a rehearing
Gullapalli Nageswara Rao v. A.P. State Road Transport Corporation, AIR 1959 SC 308 (SC)
Forum / Citation: Supreme Court of India (Constitution Bench), 1958. Reported: AIR 1959 SC 308; (1959) Supp (1) SCR 319.
Held: It is a fundamental principle of natural justice that the authority which decides must be the authority which hears; a decision rendered by one who has not heard the party, on a matter requiring a hearing, is vitiated.
Principle: Supplies the doctrinal basis for the section 129 proviso - the successor who has not heard the assessee may not decide against him over his objection without a rehearing.
Relevance: The governing natural-justice principle that section 129's proviso codifies for tax proceedings.
Institute of Chartered Accountants of India v. L.K. Ratna (1986) 4 SCC 537 (SC)
Forum / Citation: Supreme Court of India, 1986. Reported: (1986) 4 SCC 537; (1987) 164 ITR 1 (SC); AIR 1987 SC 71.
Held: A person whose rights are to be affected is entitled to a fair hearing before the authority that takes the decision; the requirement of a hearing is not an empty formality and cannot be satisfied by a decision taken without affording the affected party the opportunity to be heard by the deciding authority.
Principle: Reinforces that the right to be heard runs to the deciding authority - the value protected by the section 129 proviso.
Relevance: Confirms the content of the rehearing right that the assessee may demand under section 129.
Cluster 2 - Continuity / acts of the predecessor remain valid
Gokaraju Rangaraju v. State of Andhra Pradesh (1981) 3 SCC 132 (SC)
Forum / Citation: Supreme Court of India, 1981. Reported: (1981) 3 SCC 132; AIR 1981 SC 1473.
Held: Acts validly done by an officer in office are not undone by his ceasing to hold office; the de facto and continuity principles protect completed official acts.
Principle: A change of incumbent does not invalidate steps already validly taken; the successor builds on, rather than discards, the existing record (subject to the assessee's right to demand a rehearing).
Relevance: Underpins the continuity that section 129 is designed to secure.
