Best judgment reassessment on discovered sales records is valid when rejected books justify a rational estimate of escaped turnover.

Where account books are rightly rejected as unreliable, escaped turnover may be estimated on a best judgment basis from discovered material if the estimate bears a reasonable nexus to the facts found and is not arbitrary. The Court accepted that the bill book showing unaccounted sales for 19 days provided a rational foundation for estimating escaped turnover for the full year, and it was not necessary to prove the exact suppressed amount. On that footing, the reassessment under section 19(1) was legally sustainable, and the penalty founded on that reassessment could also stand.

Issues: (i) Whether reassessment under section 19(1) of the Madhya Pradesh General Sales Tax Act, 1958 could be made on a best judgment basis by estimating the escaped turnover from the material discovered; (ii) whether the penalty imposed on the assessee was legally sustainable in consequence of such reassessment.

Issue (i): Whether reassessment under section 19(1) of the Madhya Pradesh General Sales Tax Act, 1958 could be made on a best judgment basis by estimating the escaped turnover from the material discovered.

Analysis: The accounts maintained by the assessee were found unreliable and were rightly rejected. Once the books were discarded, the assessing authority was entitled to estimate the suppressed turnover on a rational basis. The discovered bill book revealed unaccounted sales for 19 days, and that material furnished a relevant foundation for estimating escaped turnover for the whole year. A best judgment assessment necessarily involves some guess-work, but it must not be arbitrary or capricious and must bear a reasonable nexus with the material available. The Court held that the assessing authority was not required to prove the exact suppressed turnover and that the estimate made on the basis of the discovered material was bona fide and legally sustainable.

Conclusion: The reassessment on best judgment basis was valid and the estimate of escaped turnover was justified.

Issue (ii): Whether the penalty imposed on the assessee was legally sustainable in consequence of such reassessment.

Analysis: The penalty was founded on the reassessment made for the escaped turnover. Since the reassessment itself was upheld and the estimate of escaped turnover was held lawful, the consequence that followed from that reassessment could not be treated as illegal on the ground accepted by the High Court.

Conclusion: The penalty was legally sustainable.

Final Conclusion: The assessment authority was competent to make a best judgment reassessment on the basis of the discovered material, and the connected penalty could not be invalidated on the reasoning adopted by the High Court.

Ratio Decidendi: Where account books are rightly rejected as unreliable, escaped turnover may be estimated by best judgment on the basis of relevant material, and the estimate is not vitiated merely because it contains an element of honest guess-work if it bears a reasonable nexus to the facts discovered.
