Search assessments need incriminating material, and section 40(a)(ia) cannot operate retrospectively for earlier years.

Section 40(a)(ia) was held inapplicable to an assessment year preceding its effective operation, so the labour-payment disallowance could not be sustained for that year. In search assessments under section 153A, additions for completed assessments require incriminating material found during search; absent such material, concluded matters cannot be reopened on a mere change of opinion, and the additions were therefore unsustainable. The ad hoc restriction on labour charges was upheld on a fact-specific appraisal of road-construction payments and the absence of reliable evidence for a higher estimate, while the property-related adjustment was sent for verification to avoid double taxation of the same income.

Issues: (i) Whether disallowance under section 40(a)(ia) could be sustained for the assessment year prior to the provision's effective operation. (ii) Whether additions in search assessments under section 153A could be made in respect of completed assessments without incriminating material. (iii) Whether the ad hoc disallowance of labour charges and the addition for understatement of immovable property value were sustainable on the facts.

Issue (i): Whether disallowance under section 40(a)(ia) could be sustained for the assessment year prior to the provision's effective operation.

Analysis: The disallowance rested on non-deduction of tax at source on labour payments. The relevant statutory substitution of section 40(a)(ia) was not in force for the earlier assessment year in question, and the provision could operate only from the year when it became applicable.

Conclusion: The disallowance for the earlier assessment year was not sustainable and was rightly deleted in favour of the assessee.

Issue (ii): Whether additions in search assessments under section 153A could be made in respect of completed assessments without incriminating material.

Analysis: For completed assessments, the jurisdiction under section 153A does not permit a fresh roving review of concluded matters in the absence of material found during search. Where the original assessments had already been completed and no incriminating material was brought on record, the additions amounted to a mere change of opinion and could not be sustained.

Conclusion: The additions made in respect of completed assessments were unsustainable and the relief granted by the first appellate authority was upheld in favour of the assessee.

Issue (iii): Whether the ad hoc disallowance of labour charges and the addition for understatement of immovable property value were sustainable on the facts.

Analysis: The labour disallowance was restricted on a fact-specific appreciation of the nature of road-construction work, the method of payment to labour groups, the absence of convincing evidence to support a higher estimated disallowance, and the need to avoid arbitrary estimation. As regards the property item, the matter was directed to be verified to ensure that the same income was not taxed twice.

Conclusion: The restricted disallowance, and the verification direction on the property item, were upheld, with no further interference in favour of the revenue.

Final Conclusion: The revenue's appeals failed substantially, the first appellate order was sustained on the core issues, and the matters stood concluded in favour of the assessee overall.

Ratio Decidendi: In completed assessments under section 153A, additions can be made only on the basis of incriminating material found in search, and a disallowance under section 40(a)(ia) cannot be applied retrospectively before the provision became operative.
