Reopening for non-disclosure requires suppression of primary facts; mere suspicion is insufficient, and retrospective rectification cannot validate earlier assessments.

Reopening under section 34(1)(a) required the Revenue to show omission by the assessee to disclose fully and truly all primary facts necessary for assessment; a mere suspicion about the genuineness of a lease was not a primary material fact, and disclosure of the partnership interest was sufficient, so the reassessment was invalid. Section 35(5), which treats inclusion or correction of a partner's share on firm assessment as rectification of a mistake apparent from the record, applied only from 1 April 1952 and could not be used retrospectively to alter completed individual assessments made earlier. On both grounds, the reassessments were unsustainable in law.

Issues: (i) Whether the reassessment proceedings for the assessment years 1944-45 to 1947-48 were valid under section 34(1)(a) of the Indian Income-tax Act on the footing that the assessee had failed to disclose fully and truly all material facts necessary for assessment; (ii) Whether the reassessment of the assessee's share income could be sustained under section 35(5) of the Indian Income-tax Act.

Issue (i): Whether the reassessment proceedings for the assessment years 1944-45 to 1947-48 were valid under section 34(1)(a) of the Indian Income-tax Act on the footing that the assessee had failed to disclose fully and truly all material facts necessary for assessment.

Analysis: Section 34(1)(a) can be invoked only where there has been omission or failure by the assessee to disclose fully and truly all primary facts necessary for assessment. The decisive question was whether the assessee's omission to tell the Income-tax Officer that he suspected the lease in favour of the alleged lessee was not genuine amounted to non-disclosure of material facts. The assessment records showed that the officer knew the assessee held a half share in the firm, and the assessee had done what was required by informing the department of his partnership interest and leaving the computation of the firm's income to the competent officer. A mere suspicion about the genuineness of the lease was not a primary material fact necessary for assessment, and there was no evidence of suppression of any basic or crucial fact.

Conclusion: The reassessment proceedings did not fall within section 34(1)(a) and were not valid; the question was answered in the negative and in favour of the assessee.

Issue (ii): Whether the reassessment of the assessee's share income could be sustained under section 35(5) of the Indian Income-tax Act.

Analysis: Section 35(5) deems inclusion or correction of a partner's share, on the assessment or reassessment of the firm, to be rectification of a mistake apparent from the record. That provision, however, was introduced only from 1 April 1952 and had no retrospective operation to completed individual assessments made earlier. The later assessment of the firm could not be used to justify rectification of the assessee's pre-1952 individual assessments, and the original assessments could not be altered under section 35(5) on that basis.

Conclusion: The reassessment could not be upheld under section 35(5) and that justification failed.

Final Conclusion: The reassessments were unsustainable in law and the reference was answered in favour of the assessee, with costs awarded against the department.

Ratio Decidendi: For reopening under section 34(1)(a), the Revenue must show suppression of primary and material facts by the assessee; a mere suspicion or non-disclosure of an inferential circumstance is insufficient. A provision like section 35(5) cannot be applied retrospectively to validate completed assessments made before its commencement.
