Rectification jurisdiction is limited to apparent errors on the record; merits cannot be reopened through Section 55.

Section 55 of the Tamil Nadu General Sales Tax Act, 1959 confines rectification to an error apparent on the face of the record within the prescribed period, and it cannot be used to re-examine the merits of an earlier appellate order. A rectification authority must address only the specific mistake pointed out and cannot undertake detailed reasoning, investigation, or reconsideration that belongs in appeal or revision. The authority in question went beyond this limited jurisdiction by revisiting the earlier decision instead of testing whether an apparent error existed. The writ petition was allowed and the rectification request was remanded for fresh consideration within the narrow scope of Section 55.

Issues: Whether an application for rectification under Section 55 of the Tamil Nadu General Sales Tax Act, 1959 could be used to re-examine the merits of the earlier appellate order, or was confined only to correction of an error apparent on the face of the record.

Analysis: Section 55 permits rectification only of an error apparent on the face of the record within the prescribed period. Such power cannot be exercised to correct errors that require detailed reasoning, investigation, or reconsideration of the merits, because matters of that kind fall within appeal or revision. The impugned order showed that the authority re-examined the earlier decision instead of addressing whether the specific mistake pointed out by the petitioner was an apparent error. In doing so, the authority travelled beyond the limited rectification jurisdiction and effectively acted as an appellate or reviewing authority.

Conclusion: The rectification application had to be considered only within the narrow scope of Section 55, and the impugned order was liable to be interfered with. The writ petition was allowed and the matter was remanded for fresh consideration of the rectification request.
