Proved suppression of turnover supports estimated assessment, while interest on penalty may still require Assessing Officer examination.

Suppression of purchases and sales, once proved by evidence, justified estimation of turnover, and the appellate authority's reduction of the addition to the detected suppression left no substantial question of law for revision. The main challenge therefore failed on merits. The revised demand's interest component, particularly interest on penalty, was not finally determined and was left for the Assessing Officer to examine, including the period of liability and any rectification or amnesty claim. That limited administrative direction did not affect the dismissal of the revision.

Issues: Whether suppression in purchase and sales justified estimation of turnover and whether any substantial question of law arose in revision; whether the revised demand of interest on penalty required examination by the Assessing Officer.

Issue (i): Whether suppression in purchase and sales justified estimation of turnover and whether any substantial question of law arose in revision.

Analysis: The suppression was found to be proved on evidence. The assessment had been made on an estimate by enhancing the declared turnover, and the appellate authority had already granted substantial relief by reducing the addition to the amount of suppression detected. In that situation, no substantial question of law arose for interference in revision.

Conclusion: The issue was decided against the assessee and the revision was held to be without merit.

Issue (ii): Whether the revised demand of interest on penalty required examination by the Assessing Officer.

Analysis: The revised order demanded tax, penalty, and interest, but the correctness of the interest component, particularly the levy of interest on penalty, was not finally examined in the revision. The direction was that the Assessing Officer should consider whether interest was payable on the penalty and, if so, for what period, and also examine the matter on a rectification application or settlement under the amnesty scheme.

Conclusion: The issue was left open for examination by the Assessing Officer and did not alter the dismissal of the revision.

Final Conclusion: The revision failed on the merits of the suppression and estimation dispute, with only a limited direction for administrative examination of the interest component on penalty.

Ratio Decidendi: Where suppression of turnover is proved by evidence and the appellate authority has already moderated an estimated assessment, no substantial question of law arises in revision; a limited direction on interest does not affect the dismissal of the main challenge.
