Best judgment turnover estimate fails where missing declaration forms are not linked to misuse or suppression of sales.

A best judgment turnover estimate based on alleged loss of Form XX and non-intimation under Rule 37(2) was unsustainable because the missing declaration forms were not shown to have been misused, and there was no clinching material linking them to actual sales or suppression of turnover. The assessee's explanation of change of management and misplaced records remained unrebutted by reliable evidence. In the absence of proof of misuse, revenue loss, or a rational nexus between the defect and the estimate, the assessment could not rest on conjecture or arbitrariness. The Tribunal's order in favour of the assessee was left undisturbed and the Revenue's revision was dismissed.

Issues: Whether the estimate of taxable turnover based on the alleged loss of Form XX and non-intimation under Rule 37(2) was sustainable.

Analysis: The missing declaration forms were not shown to have been misused, and the assessee explained their non-production by referring to change of management and misplaced records. The record did not contain clinching evidence to connect the missing forms with actual sales or suppression of turnover. In the absence of material showing misuse or revenue loss, a best judgment estimate could not rest on conjecture or arbitrariness and had to bear a reasonable nexus to the available materials.

Conclusion: The turnover estimate was not sustainable, and the revision failed.

Final Conclusion: The order of the Tribunal allowing the assessee's appeal was left undisturbed, and the Revenue's revision was dismissed.

Ratio Decidendi: A best judgment assessment cannot be sustained on mere suspicion or non-intimation of missing statutory forms unless there is reliable material showing misuse or suppression and a rational nexus between the defect and the turnover estimate.
