Retrospective tax validation upheld as curative amendments and rectification powers sustained against constitutional and exemption challenges.

Retrospective taxation under the Central Sales Tax (Amendment) Act, 1969 was treated as constitutionally valid because a curative or validating statute may operate retrospectively to restore the intended levy and the hardship was not shown to be unreasonable. Section 10 was upheld as a reasonable classification linked to the legislative object of relieving hardship. Section 25A of the Mysore Sales Tax Act was held available through section 9(2) of the Central Sales Tax Act, so rectification powers could be invoked. Section 8(2A) did not exempt inter-State sales merely because State tax was levied at a different stage, and a mistake apparent from the record justified rectification of the appellate order.

Issues: (i) whether the retrospective operation of the Central Sales Tax (Amendment) Act, 1969 violated Articles 19(1)(f) and 19(1)(g) of the Constitution of India; (ii) whether section 10 of the Amendment Act offended Article 14 by creating an arbitrary classification based on the date of the decision in Yaddalam's case; (iii) whether section 25A of the Mysore Sales Tax Act, 1957 was available for rectification under section 9(2) of the Central Sales Tax Act, 1956; (iv) whether section 8(2A) of the Central Sales Tax Act, 1956 exempted the petitioner's inter-State sales because the goods were taxed at the sale or purchase point under the State law; and (v) whether there was a mistake apparent from the record warranting rectification of the appellate order.

Issue (i): Whether the retrospective operation of the Central Sales Tax (Amendment) Act, 1969 violated Articles 19(1)(f) and 19(1)(g) of the Constitution of India.

Analysis: Retrospective taxation is not per se unconstitutional. The length of the retrospective period is not a decisive test by itself. A curative or validating statute may legitimately operate retrospectively to cure defects discovered through litigation and to restore the intended tax levy. The hardship caused by retrospectivity must be assessed in context, including the legislative purpose and the position of dealers during the relevant period.

Conclusion: The retrospective operation of the Amendment Act was held not to impose unreasonable restrictions and the challenge under Articles 19(1)(f) and 19(1)(g) failed.

Issue (ii): Whether section 10 of the Central Sales Tax (Amendment) Act, 1969 offended Article 14 by creating an arbitrary classification based on the date of the decision in Yaddalam's case.

Analysis: In taxation matters the Legislature enjoys wide latitude in classification. The exemption in section 10 was confined to dealers who had effected sales after 10 November 1964 and had not collected tax, while treating all dealers alike within each relevant period. The classification was designed to relieve hardship caused by retrospective validation and was linked to the legislative object.

Conclusion: Section 10 was held to be based on a reasonable classification and not violative of Article 14.

Issue (iii): Whether section 25A of the Mysore Sales Tax Act, 1957 was available for rectification under section 9(2) of the Central Sales Tax Act, 1956.

Analysis: Section 9(2) adopts the machinery of the general sales tax law of the appropriate State, including powers relating to appeals, reviews and allied procedures, for assessment and enforcement under the Central Sales Tax Act. Rectification of mistakes apparent from the record is part of the review/assessment machinery and falls within the powers adopted by section 9(2).

Conclusion: Section 25A was held to be adopted by section 9(2), and the first respondent had jurisdiction to invoke it.

Issue (iv): Whether section 8(2A) of the Central Sales Tax Act, 1956 exempted the petitioner's inter-State sales because the goods were taxed at the sale or purchase point under the State law.

Analysis: A sale is not exempt from tax generally merely because the State tax is levied at the purchase point, and a purchase is not exempt generally merely because the tax is levied at the sale point. The expression "exempt from tax generally" refers to a complete exemption from tax under the State law, not to a levy at a different stage. The contrary construction would render section 6(1A) nugatory and defeat the purpose of the validating amendment.

Conclusion: Section 8(2A) did not exempt the petitioner's inter-State sales and the contention failed.

Issue (v): Whether there was a mistake apparent from the record warranting rectification of the appellate order.

Analysis: Once the Supreme Court's ruling had superseded the earlier basis on which the appellate relief was granted, the order allowing exemption plainly conflicted with the legal position restored by the validating amendment and the later authoritative pronouncement. No elaborate reasoning was necessary to detect the error on the face of the record.

Conclusion: A mistake apparent from the record was held to exist and rectification was permissible.

Final Conclusion: The writ petition was not sustainable, and the impugned notice for rectification was allowed to stand.

Ratio Decidendi: A validating tax amendment may operate retrospectively to cure a defect and restore tax liability, and a rectification power adopted as part of the State tax machinery extends to correcting an appellate order that is inconsistent with the subsequently validated legal position.
