Additional evidence under Tribunal rules preserves factual findings where reappreciation reveals no perversity or substantial legal question.
Rule 18(4) of the Income-tax (Appellate Tribunal) Rules permits additional evidence through a separate paper book supported by an application explaining the reasons for its production. Records lost, damaged or soiled and subsequently retrieved may therefore be received and evaluated under that procedure. Evidence-based findings on additions, including Section 68 additions, remain factual where supported by confirmations, transaction details, accounts, banking records, certificates and related material. In the absence of perversity, a challenge requiring reappreciation of that material does not raise a substantial question of law.
Issues: (i) Whether the Tribunal lawfully admitted the assessee's additional evidence under Rule 18(4) of the Income-tax (Appellate Tribunal) Rules, 1963; (ii) Whether the Revenue's challenge to the Tribunal's factual findings on the additions, including the Section 68 additions, raised a substantial question of law.
Issue (i): Whether the Tribunal lawfully admitted the assessee's additional evidence under Rule 18(4) of the Income-tax (Appellate Tribunal) Rules, 1963.
Analysis: Rule 18(4) permits a party to tender additional evidence through a separate paper book accompanied by an application explaining the reasons. The records for the relevant year had been lost, damaged or soiled and were subsequently retrieved. The material was therefore lawfully received and evaluated.
Conclusion: Admission and consideration of the additional evidence was lawful.
Issue (ii): Whether the Revenue's challenge to the Tribunal's factual findings on the additions, including the Section 68 additions, raised a substantial question of law.
Analysis: The findings on the impugned additions were founded on confirmations, transaction details, accounts, banking records, an accountant's certificate and other supporting documents. As the final fact-finding authority, the Tribunal had given detailed reasons for accepting the evidence, deleting certain additions, confirming one addition and restricting others. No perversity was established.
Conclusion: No substantial question of law arose from the evidence-based findings on the additions.
Final Conclusion: The statutory entitlement to furnish additional evidence was recognised, and the fact-based relief granted on the challenged additions remained undisturbed.
Ratio Decidendi: Where the final fact-finding authority admits additional evidence in conformity with Rule 18(4) and reaches evidence-based findings free from perversity, a challenge seeking reappreciation of that evidence does not give rise to a substantial question of law.
