Prospective cancellation of eligibility certificates under tax rules cannot operate retrospectively, even where fraud is alleged.

Rule 101 of the West Bengal Sales Tax Rules, 1995 was construed as permitting an authority, after hearing the dealer, to declare an eligibility certificate invalid only prospectively from the date specified in the order or a later date. Because dealers and third parties may act on the faith of a valid certificate, retrospective invalidation would unsettle completed transactions and affect commercial certainty. Allegations of fraud or misrepresentation did not expand the statutory power to authorise cancellation from inception. The stated position is that retrospective cancellation of the eligibility certificate was impermissible and the power under rule 101 was confined to prospective operation.

Issues: Whether an eligibility certificate granted under section 39 of the West Bengal Sales Tax Act, 1994 could be declared invalid with retrospective effect under rule 101 of the West Bengal Sales Tax Rules, 1995, even on allegations of fraud and misrepresentation.

Analysis: Rule 101 empowers the authority, after hearing the dealer, to declare an eligibility certificate invalid from such date as may be specified in the order. The expression was construed in the context of the statutory scheme and the commercial consequences of certificate-based transactions. Since dealers and other persons may act on the faith of the certificate while it remains operative, retrospective cancellation would unsettle completed transactions and adversely affect third-party interests. The authority, therefore, could act only prospectively, from the date of the order or a later date, and could not travel beyond the limits of the rule. The allegation of fraud did not enlarge the statutory power so as to permit retrospective invalidation.

Conclusion: Retrospective cancellation of the eligibility certificate was impermissible. The challenge by the Revenue failed and the certificate could not be invalidated from its inception.

Final Conclusion: The statutory power under rule 101 was held to be prospective only, and the order cancelling the eligibility certificate with retrospective effect was not sustained.

Ratio Decidendi: Where a taxing statute authorises an authority to declare an eligibility certificate invalid from such date as may be specified, the power is confined to prospective operation unless the statute clearly permits retrospectivity.
