Best judgment assessment does not automatically justify penalty; nondisclosure must be separately proved under sales tax law.

Best judgment assessment under the Tamil Nadu General Sales Tax Act does not by itself establish penalty liability. The court held that limitation under section 16(1)(a) was inapplicable because the proceedings were treated as assessments under section 12(2), not escaped-turnover proceedings. It also sustained tax on the disputed turnover because the dealers failed to prove that the imported art silk was sold outside Tamil Nadu and never brought into the State. However, penalty under section 12(3) was set aside, as penal action requires a further judicial finding that actual turnover existed and was not disclosed, which cannot be inferred merely from a best judgment estimate.

Issues: (i) Whether the assessment was barred by limitation under section 16(1)(a) of the Tamil Nadu General Sales Tax Act, 1959. (ii) Whether the turnover brought to tax was liable to sales tax on the facts found. (iii) Whether penalty under section 12(3) of the Tamil Nadu General Sales Tax Act, 1959 could be imposed merely because the assessment was made on best judgment basis.

Issue (i): Whether the assessment was barred by limitation under section 16(1)(a) of the Tamil Nadu General Sales Tax Act, 1959.

Analysis: The proceedings were treated as assessments under section 12(2), not as escaped turnover proceedings under section 16. Since the assessment arose in the course of section 12 proceedings, the limitation plea based on section 16(1)(a) was inapplicable.

Conclusion: The plea of limitation was rejected.

Issue (ii): Whether the turnover brought to tax was liable to sales tax on the facts found.

Analysis: The dealers failed to establish their plea that the imported art silk was sold in Bombay and never brought into Tamil Nadu. In the absence of proof supporting the claimed outside sale, an inference that the goods were brought into the State, converted and sold there was sustained for assessment purposes.

Conclusion: The turnover was held liable to tax.

Issue (iii): Whether penalty under section 12(3) of the Tamil Nadu General Sales Tax Act, 1959 could be imposed merely because the assessment was made on best judgment basis.

Analysis: Penalty proceedings require more than the mere fact of a best judgment assessment. The imposition of penalty depends on a judicial determination that there was actual turnover and that such turnover was not disclosed. A best judgment estimate may support assessment, but it does not automatically establish the higher level of proof needed for penalty. The reasoning drew support from the distinction between assessment and penalty, and from the principle that penal liability is not to be treated as automatic on every estimate.

Conclusion: The penalty was held unsustainable and was set aside.

Final Conclusion: The revision succeeded only on the penalty question. The assessment and tax liability were maintained, but the penalty was annulled because best judgment assessment alone did not justify penal action without proof of non-disclosure warranting such consequence.

Ratio Decidendi: Penalty for non-disclosure cannot rest solely on a best judgment assessment; it requires a further judicial finding that actual turnover existed and was not disclosed.
