Prospective effect of tax clarification bars retrospective reclassification and enhanced liability under the earlier departmental position.

A revenue clarification issued by the Commercial Taxes authority was treated as executive in character and binding on the department while it remained in force. The principle applied was that such departmental clarifications may guide assessment, but any withdrawal or change can operate only prospectively and cannot be used to prejudice an assessment already governed by the earlier position. On that basis, the later clarification could not justify retrospective reclassification of compacting machinery or an enhanced tax liability for the relevant assessment year, and the assessment order was quashed.

Issues: Whether the clarification issued by the Commissioner of Commercial Taxes could be applied retrospectively so as to justify reclassification of compacting machinery and enhance the tax liability for the assessment year in question.

Analysis: A clarification issued by the revenue authority under the relevant statutory provision was treated as executive in character and binding on the department so long as it remained in force. The legal position applied was that such clarifications may guide departmental action, but if withdrawn or altered, the change can operate only prospectively and cannot prejudicially affect assessments already governed by the earlier clarification. The Court distinguished decisions dealing with general government opinions or difficulty-removal powers and relied on the principle that departmental circulars and clarifications, when in force, control the revenue's conduct.

Conclusion: The clarification dated November 23, 2005 could operate only prospectively and could not be used to reopen or enhance the assessee's tax liability for the year under assessment. The assessment order was quashed.
