Block assessment of undisclosed arrack sales turns on seized evidence, proven nexus for set-off, and levy of interest and surcharge.

In block assessment based on search material, undisclosed arrack sales may be estimated from seized evidence, prevailing sale patterns and excise notification rates, with excise duty included where part of the realisation. A set-off of miscellaneous receipts against suppressed arrack income is permissible only on proof of a clear evidentiary nexus between the receipts and the undisclosed business income. Interest on the block demand was treated as leviable, and surcharge was sustained subject to the then-prevailing understanding of section 113 and the Supreme Court Larger Bench position.

Issues: (i) Whether the sale price of unaccounted arrack and the inclusion of excise duty were correctly determined; (ii) whether the assessee was entitled to set off miscellaneous receipts against undisclosed income from arrack business; and (iii) whether interest and surcharge were leviable on the block assessment demand.

Issue (i): Whether the sale price of unaccounted arrack and the inclusion of excise duty were correctly determined.

Analysis: The search material established large-scale unaccounted sale of arrack both within and outside the assessee's own territory. The Tribunal's estimate of Rs. 9 per sachet for sales within the assessee's territory and Rs. 1.60 per sachet for sales outside the territory, together with excise duty, was founded on the material on record, the prevailing sale structure and the excise notification rate, and was neither arbitrary nor perverse.

Conclusion: The determination of sale price and inclusion of excise duty were upheld, against the assessee.

Issue (ii): Whether the assessee was entitled to set off miscellaneous receipts against undisclosed income from arrack business.

Analysis: The assessee did not establish any reliable nexus between the miscellaneous receipts shown in the regular returns and the unaccounted arrack . The authorities below had given cogent reasons for rejecting the claim, and the Tribunal's allowance of set off was not supported by evidence linking those receipts to the suppressed arrack income.

Conclusion: The set-off was disallowed, in favour of Revenue.

Issue (iii): Whether interest and surcharge were leviable on the block assessment demand.

Analysis: Excise duty was part of the sale realization outside the territory, and the levy of interest under the block assessment provisions was justified. Surcharge was also upheld in view of the then-prevailing understanding of section 113, though its ultimate position was stated to remain subject to the decision of the Larger Bench of the Supreme Court.

Conclusion: Interest was upheld and surcharge was upheld subject to the larger bench decision, against the assessee.

Final Conclusion: The Tribunal's view was sustained on the sale-price determination, but the set-off granted to the assessee was reversed, leaving the Revenue substantially successful and the assessee's appeal dismissed.

Ratio Decidendi: In block assessment based on search material, undisclosed profits may be estimated from seized evidence and prevailing market/excise indicators, but a set-off against such income is permissible only when a clear evidentiary nexus between the claimed receipts and the undisclosed business income is proved.
