Reassessment for non-disclosure fails where primary facts were disclosed and reopening rests only on a change of opinion.

Reassessment under section 34(1)(a) of the Indian Income-tax Act, 1922 requires a bona fide reason to believe that income escaped assessment because the assessee omitted or failed to disclose fully and truly all material facts. Once primary facts are disclosed, the assessing authority must draw the correct legal inference, and a later change of opinion on the same materials does not justify reopening. On the facts noted, the alleged non-disclosure of the Eastern Bank account was not established, the assessee consistently maintained disclosure, and the prior assessments already reflected knowledge of the racing receipts. The reopening notices were therefore invalid for want of the statutory precondition.

Issues: Whether the notices issued for reopening the assessments were valid under section 34(1)(a) of the Indian Income-tax Act, 1922 on the ground that the assessee had omitted or failed to disclose fully and truly all material facts necessary for assessment.

Analysis: The statutory condition for action under section 34(1)(a) is that the Income-tax Officer must have reason to believe that income has escaped assessment because of the assessee's omission or failure to make a full and true disclosure of material facts. Once the assessee has disclosed the primary facts, the assessing authority must draw the proper legal inference, and a subsequent change of opinion on the same facts does not justify reopening. On the materials available, the alleged non-disclosure of the Eastern Bank account was not established; the assessee consistently asserted disclosure, the respondents did not produce the relevant order-sheets or records despite direction of the Court, and the prior assessments showed that the racing receipts had long been known and treated as a hobby or casual receipt.

Conclusion: The notices were invalid, as there was no omission or failure by the assessee to disclose primary facts and no legal basis for reopening the assessments under section 34(1)(a).

Ratio Decidendi: Reassessment under section 34(1)(a) cannot be founded on a mere change of opinion where the assessee has disclosed the primary facts; the statutory precondition is an actual failure to disclose fully and truly all material facts leading to escaped assessment.
