Additional evidence in tax appeals cannot be used to introduce a new case or sustain a finding without admissible proof.

Rule 29 of the Appellate Tribunal Rules, 1946 does not permit a party to introduce an entirely new case at the appellate stage; additional evidence is confined to situations where the Tribunal needs it to decide the appeal, where there is substantial cause, or where the assessee lacked a sufficient opportunity before the Income-tax Officer. The Madhya Pradesh High Court held that the assessee's new explanation and affidavit were wrongly admitted because they had not been raised before the lower authorities. Once that material was excluded, no admissible evidence remained to support the Tribunal's finding that the sum was not credited in cash on 24 March 1954, so the finding could not stand.

Issues: (i) Whether the Tribunal was justified in admitting and relying upon a new explanation and affidavit tendered for the first time before it to support the assessee's case. (ii) Whether, after excluding that material, there remained any evidence to support the Tribunal's finding that the sum of Rs. 50,000 was not credited in cash by the assessee on 24 March 1954.

Issue (i): Whether the Tribunal was justified in admitting and relying upon a new explanation and affidavit tendered for the first time before it to support the assessee's case.

Analysis: The power to receive additional evidence under Rule 29 of the Appellate Tribunal Rules, 1946, is limited to cases where the Tribunal itself requires such evidence to enable it to pass orders, where there is substantial cause, or where the assessee was denied a sufficient opportunity by the Income-tax Officer. That power does not extend to permitting a party to set up an altogether new case at the appellate stage. The assessee's later version was not raised before the Income-tax Officer or the Appellate Assistant Commissioner and was therefore outside the proper scope of the rule. The affidavit and supporting material were thus wrongly admitted.

Conclusion: The Tribunal was not justified in taking the new affidavit and supporting material into consideration.

Issue (ii): Whether, after excluding that material, there remained any evidence to support the Tribunal's finding that the sum of Rs. 50,000 was not credited in cash by the assessee on 24 March 1954.

Analysis: Once the improperly admitted affidavit and fresh material were excluded, nothing remained to sustain the Tribunal's conclusion. The purported ledger entry was not relied upon by the Tribunal as a basis for its finding, and the record contained no other material capable of supporting the conclusion reached. A finding unsupported by admissible evidence cannot stand.

Conclusion: There was no evidence to support the Tribunal's finding.

Final Conclusion: The reference was answered in favour of the Revenue, and the assessee's new case and supporting affidavit were held to be inadmissible.

Ratio Decidendi: Additional evidence in income-tax appeal proceedings cannot be admitted to permit a party to set up a new case, and a finding based solely on such inadmissible material is unsupported by evidence in law.
