Undisclosed income in block assessment and building valuation rates turn on seized material and factual appraisal.

In block assessment, an amount found from seized material may be treated as undisclosed income even if it appears in regular cash books, where it was not shown in returns and the assessee fails to prove the credits or produce supporting evidence. On valuation of a constructed building, the choice between PWD and CPWD rates depends on factual factors such as location, materials and utility, and the finding will not be interfered with unless perverse. The amount of Rs. 41,400 was therefore restored as undisclosed income, while the Tribunal's valuation finding was left undisturbed.

Issues: (i) whether the sum of Rs. 41,400, reflected in seized regular cash books but not satisfactorily explained, constituted undisclosed income in block assessment; and (ii) whether the Tribunal was justified in adopting PWD rates instead of CPWD rates for valuation of the constructed building.

Issue (i): whether the sum of Rs. 41,400, reflected in seized regular cash books but not satisfactorily explained, constituted undisclosed income in block assessment.

Analysis: Under Chapter XIV-B, income that has not been disclosed and is found on the basis of material seized during search can be brought to tax as undisclosed income. The mere fact that entries appear in regular books does not prevent inclusion where the assessee had not filed returns, had not disclosed the amount as income, and failed to prove the genuineness of the credits or produce the creditors.

Conclusion: The amount of Rs. 41,400 was undisclosed income and the Tribunal was not right in deleting the addition.

Issue (ii): whether the Tribunal was justified in adopting PWD rates instead of CPWD rates for valuation of the constructed building.

Analysis: Valuation of construction depends on the relevant facts, including location, materials used, and utility of the building, and there is no rigid formula requiring exclusive adoption of either PWD or CPWD rates. Since the question turns largely on factual findings, interference is not warranted unless the finding is perverse.

Conclusion: The Tribunal's view on adoption of PWD rates was not interfered with.

Final Conclusion: The addition of Rs. 41,400 was restored, while the Tribunal's valuation finding was left undisturbed, resulting in a partly allowed appeal.

Ratio Decidendi: In a block assessment, an amount found from seized material may be treated as undisclosed income even if reflected in regular books, where it was not disclosed in returns and its genuineness is not proved; valuation of construction is a fact-based exercise where no inflexible rule mandates PWD or CPWD rates.
