Rectification is limited to obvious errors on the record, not debatable classification disputes requiring interpretation.

Rectification under section 43 of the Kerala General Sales Tax Act is confined to an obvious and patent mistake apparent from the record, on the same limited footing as section 154 of the Income-tax Act. A classification issue that requires argument, interpretation, or reconsideration of the merits is not a rectifiable error. The classification of X-ray films was treated as a contested and debatable question, reflected in differing Tribunal views and the assessee's earlier stand on electrical goods. The rectification application was therefore not maintainable and was rightly rejected.

Issues: Whether the application for rectification under section 43 of the Kerala General Sales Tax Act, 1963 was maintainable on the ground that the classification of X-ray films under the relevant schedule entry involved a mistake apparent on the face of the record.

Analysis: The rectification power under section 43 is confined to an obvious and patent error apparent from the record, analogous to the limited power under section 154 of the Income-tax Act, 1961. A point that requires argument, interpretation, or a long-drawn process of reasoning cannot be treated as such an error. The classification of X-ray films was shown to be a contested and debatable issue, as reflected by the differing views within the Tribunal itself and by the assessee's own earlier stand that the goods were electrical goods. The matter therefore did not disclose any self-evident mistake capable of rectification.

Conclusion: The rectification application was not maintainable and was rightly rejected.

Ratio Decidendi: Rectification is permissible only for an obvious error apparent on the face of the record, and not for a debatable issue that requires interpretative reasoning or reconsideration of the merits.
