Case Note & Summary
The dispute arose between the Deputy Commissioner of Sales Tax and various registered dealers under the Kerala General Sales Tax Act, 1963, regarding the applicability of the Kerala Additional Sales Tax Act, 1978 on inter-state sales. The Kerala Additional Sales Tax Act sought to impose an additional sales tax of 10% on the existing rates under the Kerala General Sales Tax Act. The assesses challenged the levy of this additional tax on inter-state sales, arguing that it could not be considered as a levy under the sales tax law of the appropriate State as defined in the Central Sales Tax Act. The High Court upheld their challenge, leading to the State's appeal to the Supreme Court. The Supreme Court analyzed the definitions and provisions of the Central Sales Tax Act and concluded that the additional sales tax does indeed constitute sales tax under the local law, thus affecting the rates applicable to inter-state sales. The court emphasized that the current rate of tax under the local Act must be considered for determining the tax on inter-state sales, including any amendments made to the local tax law. The court ultimately allowed the appeals, restoring the assessment orders that included the additional sales tax in the calculation of inter-state sales tax liability, while clarifying that any notifications under Section 8(5) of the Central Sales Tax Act would not be affected by amendments to the local Act unless specifically modified. No costs were awarded in the decision.
