Rectification notice prevails over caption; revision remains confined to the existing record and cannot examine later refund claims.

In rectification proceedings, the substance of a notice prevails over its caption: a notice referring to an earlier assessment, a retrospective tax amendment, and proposed alteration of the assessment was treated as one under the rectification provision, not as an escaped-assessment notice. The opportunity of hearing requirement was satisfied by inviting written objections and considering the response, as a personal oral hearing is not always necessary. In revision, the authority's jurisdiction was confined to the legality and propriety of the order on the existing record, so it could not investigate a later refund claim that was not before the assessing authority.

Issues: (i) Whether the notice dated 10 February 1970 was one under section 12-A or section 25-A of the Karnataka Sales Tax Act, 1957; (ii) Whether the appellant was afforded the opportunity of being heard contemplated by section 25-A; (iii) Whether, in revision under section 21, the revisional authority could investigate the alleged subsequent refund of tax so as to grant exemption under the Central Sales Tax (Amendment) Act, 1969.

Issue (i): Whether the notice dated 10 February 1970 was one under section 12-A or section 25-A of the Karnataka Sales Tax Act, 1957.

Analysis: The two provisions serve distinct purposes: section 12-A deals with escaped turnover, while section 25-A concerns rectification of mistakes apparent from the record. The notice, though captioned under section 12-A, referred to the earlier assessment, the exemption granted in light of the Yaddalam decision, the retrospective amendment to the Central Sales Tax law, and the proposal to alter the earlier assessment on the basis of the amendment. It did not contain the essential ingredients of an escaped-assessment notice. The substance of the notice therefore indicated a proposed rectification of the earlier order.

Conclusion: The notice was held to be a notice under section 25-A and not under section 12-A.

Issue (ii): Whether the appellant was afforded the opportunity of being heard contemplated by section 25-A.

Analysis: The notice invited written objections within seven days and clearly set out the proposed rectification. The appellant submitted objections, but did not seek a further personal hearing or any additional opportunity. The requirement of opportunity under the rectification provision is a fair hearing before adverse action, not necessarily a personal oral hearing in every case. On the facts, the opportunity given was adequate and satisfied the requirements of natural justice.

Conclusion: Adequate opportunity was held to have been afforded to the appellant.

Issue (iii): Whether, in revision under section 21, the revisional authority could investigate the alleged subsequent refund of tax so as to grant exemption under the Central Sales Tax (Amendment) Act, 1969.

Analysis: Revisional power under section 21 is confined to examining the legality, propriety and regularity of the order and the record on which it was based. The alleged subsequent refund was not part of the material before the assessing authority when the rectification proceedings were taken up, and the revisional authority was not required to embark on an inquiry into later events outside that record. The appellant's reliance on decisions permitting wider enquiry did not alter the statutory limits of the revisional jurisdiction in the present scheme.

Conclusion: The revisional authority was correctly held to have no competence to investigate the subsequent refund claim.

Final Conclusion: The assessment notices were properly treated as rectification notices, the appellant was given sufficient opportunity, and the revisional authority acted within its jurisdiction in declining to examine the later refund claim. The appeals were therefore not entitled to succeed.

Ratio Decidendi: In rectification proceedings, the substance of the notice prevails over its caption, and the revisional authority's inquiry is confined to the record and material that formed part of the proceedings below; it cannot reopen the matter on the basis of later facts not before the assessing authority.
