Retrospective tax legislation upheld where the legislature had competence to levy the tax and cure ambiguity.

Retrospective tax legislation was examined in relation to the Haryana General Sales Tax Act's definition of "dealer" under section 2(c), applied retrospectively from 7 September 1955. The analysis states that the amendment continued the earlier sales tax framework, was intended to clarify legislative intent, remove ambiguity, and close loopholes exposed by judicial decisions. It further states that a legislature competent to impose a tax prospectively is equally competent to impose it retrospectively, and that the duration of the retrospective period is immaterial if legislative competence exists. The retrospective operation was concluded to be constitutional and valid.

Issues: Whether the retrospective effect given to the definition of "dealer" in section 2(c) of the Haryana General Sales Tax Act, 1973, with effect from 7 September 1955, was unconstitutional.

Analysis: The definition of "dealer" under the Haryana Act substantially continued the earlier sales tax law but was given retrospective operation by section 1(3). The retrospective amendment was enacted against a background of conflicting interpretations on the taxability of exported and processed goods and was intended to clarify the legislative intent, remove ambiguity, and plug loopholes exposed by judicial decisions. The Court further held that, as a matter of constitutional power under the taxing entry, the legislature competent to impose a tax prospectively is equally competent to impose it retrospectively. The contention that retrospectivity is permissible only for removing ambiguity or curing defects was rejected, and the length of the retrospective period was held to be immaterial so long as legislative competence existed.

Conclusion: The retrospective effect given to section 2(c) was held to be constitutional and valid.

Ratio Decidendi: A legislature competent to levy a tax prospectively may also levy it retrospectively, and retrospective tax legislation is constitutionally valid even where it creates liability for a period during which the goods were not earlier taxable.
