Rectification proceedings must follow their true substance, and a tax order based on a wrong factual premise cannot stand.

A tax proceeding described as rectification was treated according to its substance, not its label, so limitation under the prescribed five-year period applied rather than a later reopening. The Madras High Court noted that the assessment record already disclosed and accepted the snack purchases, while the revision notice incorrectly proceeded as if no purchase details had been produced. Because the action was founded on a demonstrably wrong factual premise and showed non-application of mind, the impugned order was considered unsustainable on merits as well as time-barred.

Issues: (i) whether the impugned proceedings were barred by limitation under Section 55(1) of the TNGST Act, 1959; (ii) whether the impugned order could be sustained on merits in view of the factual error regarding the snack purchases and the assessment of the hotel under the applicable tax entry.

Issue (i): Whether the impugned proceedings were barred by limitation under Section 55(1) of the TNGST Act, 1959.

Analysis: The assessment order had been passed on 22.02.2007, whereas the impugned order was passed nearly nine years later. The Court held that the nature of the proceeding had to be gathered from its substance and recitals, and not merely from the label or provision quoted. Since the proceedings were in substance meant to correct an apparent error in the assessment, they could be exercised only within the prescribed period of five years.

Conclusion: The proceedings were barred by limitation and were unsustainable.

Issue (ii): Whether the impugned order could be sustained on merits in view of the factual error regarding the snack purchases and the assessment of the hotel under the applicable tax entry.

Analysis: The original assessment record showed that the snack purchases were already disclosed, verified and accepted. The revision notice proceeded on the incorrect premise that no purchase details had been produced. The notice also disclosed that the authority considered the original assessment to have been made under the wrong tax entry and sought to alter the rate accordingly. This demonstrated a factual mistake and non-application of mind in the impugned action.

Conclusion: The impugned order was erroneous on merits and could not be sustained.

Final Conclusion: The writ petition succeeded and the assessment order was set aside, as the impugned action was time-barred and also vitiated by factual error.

Ratio Decidendi: Where the substance of a tax proceeding is to correct an apparent assessment error, it must be taken to be a rectificatory action governed by the prescribed limitation period, and an order founded on a demonstrably incorrect factual premise cannot be sustained.
