Case Note & Summary
The dispute arose from the collection of sales tax on Arrack, a type of liquor, by the State of Mysore from licensed contractors. The appellants, who were excise contractors, challenged the validity of the sales tax collection that included excise duty and cesses. The High Court ruled in favor of the appellants, stating that sales tax could not be levied on excise duty, leading to the State's withdrawal of its appeal. Subsequently, the State enacted the Mysore Sales Tax (Amendment) Act, 1969, which increased the sales tax rate retroactively to avoid refunding the excess amounts collected. The appellants contended that the amendment was arbitrary and did not rectify the defects identified by the High Court. The Supreme Court analyzed the amendment's purpose and found it aimed to nullify the High Court's judgment rather than remedy the identified issues. The Court held that the retrospective increase in sales tax was unreasonable and unconstitutional, as it did not address the underlying legal defects and merely sought to retain amounts collected illegally. The Court ultimately ruled in favor of the appellants, declaring the amendment invalid and upholding the High Court's earlier decision regarding the illegality of the sales tax collection on excise duty and cesses.
