Rule 29 ITAT Additional Evidence Cannot Be Used to Retract a Voluntary Return: Kerala High Court on Afterthought Affidavits in Cash Seizure Assessments

1. Introduction

The decision of the Kerala High Court in UMA MAHESHWARA RAO CHINNI v. ASSISTANT COMMISSIONER OF INCOME TAX (along with the connected appeal of Sravan Kumar Neela), Citation: 2025 KER 68910, decided on 17-09-2025, addresses a recurring problem in search/seizure-related assessments: whether an assessee who has voluntarily offered seized cash as “income from other sources” in the return can later, at the appellate stage, attempt to “explain” the cash through affidavits and supporting material so as to escape treatment under Section 69A and the higher tax regime under Section 115BBE.

The background is a seizure of Rs.2,39,57,500/- from three bus passengers travelling from Hyderabad to Kozhikode. Income-tax authorities took custody of the cash. Two of the passengers—Sravan Kumar Neela and Uma Maheshwara Rao Chinni—each submitted letters declaring their respective portions of the seized cash as income for FY 2016-17, filed returns accordingly, and were assessed by treating the sums as “unexplained money” under Section 69A with tax demanded under Section 115BBE. Their appeals ultimately failed before the ITAT, which refused to rely on additional evidence produced for the first time at the Tribunal stage. The High Court was asked to interfere with that refusal.

The core issue therefore was not merely “source of cash”, but a more pointed procedural-substantive question: can Rule 29 additional evidence be invoked at the ITAT stage in a manner that effectively rewrites a voluntarily filed return?

2. Summary of the Judgment

The High Court dismissed both appeals and upheld the ITAT’s order dated 15.04.2024. It held, in substance, that:

  • While the ITAT can admit additional evidence under Rule 29 of the Income Tax (Appellate Tribunal) Rules, 1963, additional evidence is not automatically admissible or binding on the Tribunal.
  • On the facts, the affidavits and materials produced at the ITAT stage were belated, inconsistent with earlier stands, and amounted to an afterthought.
  • Permitting the assessees to rely on such evidence would, in effect, amount to permitting a revision of the voluntarily filed returns, which the Court said is not permissible under the statutory scheme.
  • The ITAT’s findings were essentially factual and did not warrant interference.

3. Analysis

3.1 Precedents Cited

The judgment does not cite any prior case law. The Court’s reasoning is anchored in the text and operation of: Rule 29 of the ITAT Rules, and the statutory consequences of offering income and being assessed under Section 69A read with Section 115BBE.

As a result, the decision functions less as a “precedent-following” judgment and more as a “rule-application” decision, signalling a stricter approach to late-stage evidentiary manoeuvres that would undo a voluntary disclosure already made in the return.

3.2 Legal Reasoning

(a) The Court’s reading of Rule 29 (additional evidence before the ITAT)

Rule 29 states that parties are not entitled to produce additional evidence before the Tribunal, but the Tribunal may allow it (for reasons to be recorded) in specified situations, including where:

  • the Tribunal requires the material “to enable it to pass orders” or “for any other substantial cause”, or
  • the income-tax authorities decided the case without giving sufficient opportunity to the assessee to adduce evidence.

The High Court emphasised that additional evidence should be accepted only where the assessee was prevented from adducing such evidence earlier (and, on the facts, found no such prevention). It noted that:

  • Uma Maheshwara Rao Chinni’s claim that the cash belonged to one D. Ramesh was not supported by evidence at the earlier stage, and Ramesh did not claim the money at the “original stage”.
  • Sravan Kumar Neela and Uma Maheshwara Rao Chinni took different stands as to the purpose of carrying cash (gold jewellery retail store; petroleum business investment), and later produced affidavits to introduce new “source” narratives.
  • Uma Maheshwara Rao Chinni was ex parte before the first appellate authority, weakening any claim that he was denied opportunity.

(b) Voluntary return disclosure as a “binding anchor” against later re-characterisation

The fulcrum of the decision is the Court’s conclusion that once the assessees: (i) wrote letters declaring the seized cash as their income, and (ii) filed returns offering it as “income from other sources”, the late-stage attempt to explain the sums through affidavits would effectively result in revising the voluntarily filed return through appellate proceedings—something the Court said is “not possible under the statute”.

This reasoning reflects a policy concern: appellate forums are not to be used as a reset button for a conscious disclosure made in the return, especially where the assessee’s later case depends on newly created affidavit evidence.

(c) Characterisation of affidavits as “afterthought” evidence

The High Court agreed with the ITAT that the affidavits produced at the Tribunal stage were an afterthought, given the timing and the shift in narrative. The Court treated these fact patterns as justifying the ITAT’s discretion not to “act on” such evidence even if filed.

3.3 Impact

This judgment is likely to have the following practical effects in income-tax appellate practice, particularly in cases involving cash seizures and additions under Section 69A:

  • Higher threshold for late affidavits: Assessees may find it harder to introduce affidavit-based “source explanations” at the ITAT stage if they were not pursued before the Assessing Officer or the first appellate authority.
  • Voluntary disclosure is hard to unwind: Where an assessee has offered an amount in the return (especially following seizure), attempts to later re-characterise it as belonging to someone else or as sourced funds may be viewed as impermissible “return revision” through appeal.
  • Rule 29 discretion reaffirmed: The decision underscores that Rule 29 is not an entitlement; admission and reliance upon additional evidence is discretionary, fact-sensitive, and can be denied where the Tribunal perceives strategic afterthoughts.
  • Incentive to build the record early: Taxpayers in seizure-related matters must front-load their evidentiary record at assessment/first appeal stages, or risk being shut out later.

4. Complex Concepts Simplified

  • Section 69A (Unexplained money): If a person is found to be the owner of money and cannot satisfactorily explain its nature and source, the amount may be treated as the person’s income for that year.
  • Section 115BBE: A special, typically higher tax regime applicable to certain “deemed income” additions such as those under Section 69A. The practical consequence is that once an amount is taxed under this route, the tax burden is heavier and the scope for set-offs/deductions is constrained.
  • Rule 29 of the ITAT Rules: A procedural rule governing when the ITAT may permit new evidence at the Tribunal stage. It is exceptional, not routine; parties do not have an automatic right to file fresh evidence.
  • “Afterthought” evidence: Evidence created or produced late in the process, especially after earlier positions become inconvenient, which may be viewed as less reliable and strategically motivated.
  • Ex parte before the first appellate authority: If a party does not participate, they generally weaken later arguments that they lacked opportunity to file evidence.

5. Conclusion

The Kerala High Court’s ruling in UMA MAHESHWARA RAO CHINNI v. ASSISTANT COMMISSIONER OF INCOME TAX cements a clear message: Rule 29 cannot be deployed to introduce belated evidence that effectively retracts or revises a voluntary income disclosure made in the return, particularly in cash seizure cases where shifting narratives emerge only at the ITAT stage. By endorsing the ITAT’s refusal to rely on late affidavits as an “afterthought”, the Court strengthens procedural discipline in tax litigation and signals that “source explanations” must be timely, consistent, and supported at the earliest stages of assessment and first appeal.
