Best judgment sales tax assessment upheld where fair estimation was made from available material and opportunity to produce evidence was given

Best judgment sales tax assessment is sustainable where the dealer fails to produce account books or credible material to prove actual turnover, and the assessing authority makes a fair estimate on available evidence and surrounding circumstances. The Calcutta HC noted that repeated opportunities were given, objections and evidence were considered under Rule 54, and reasons were recorded for the estimated turnover. An assessment will not fail merely because it rests on estimation, provided the authority acts honestly and not dishonestly, vindictively, or capriciously; the appellate reduction of the taxable turnover was also upheld on that basis.

Issues: Whether the sales tax assessment made by the authorities to the best of their judgment, and as modified in appeal, was legally sustainable.

Analysis: The dealers failed to produce account books or furnish positive materials to show the actual turnover, despite repeated opportunities. In such circumstances, the assessing authority was required to make a fair estimate on the available materials and surrounding circumstances. The appellate authority reduced the estimated taxable turnover after considering the record, and the Board upheld that order. The governing principle is that a best judgment assessment is valid if the officer acts honestly, considers the relevant materials, and does not act dishonestly, vindictively, or capriciously. Rule 54 required consideration of objections and evidence, and the record showed that the authorities gave the dealers full opportunity and recorded reasons for their conclusions.

Conclusion: The assessment was made to the best of the authorities' judgment. The answer to the reference was in the affirmative, against the assessee and in favour of the Revenue.

Ratio Decidendi: A best judgment assessment is not invalid merely because it involves estimation; it is sustainable if the authority honestly forms a fair estimate on the materials available and the assessee has been given an opportunity to produce evidence.
