In a significant judicial development concerning the constitutional powers of State Legislatures to levy additional sales tax or surcharge, a Seven-Judge Constitution Bench of the Hon’ble Supreme Court, headed by Chief Justice of India Justice Surya Kant, has held that the nearly 27-year-old constitutional reference concerning additional levies on sales tax has become academic and infructuous following the introduction of the Goods and Services Tax (GST) regime in India.
Supreme Court Clarifies Legislative Competence of States
The Apex Court observed that an additional tax or surcharge computed as a percentage of an existing sales tax liability essentially represents an enhancement of the rate of sales tax. Accordingly, such a levy retains its character as a tax on the sale or purchase of goods and falls within the legislative competence of States under Entry 54 of List II of the Seventh Schedule to the Constitution of India, as it stood prior to the GST regime. The mere adoption of sales tax payable as the measure for calculating an additional levy does not, by itself, convert such levy into a tax on the income of a dealer under Entry 82 of List I.
Background: Constitutional Dispute Over Additional Sales Tax
The dispute originated in Arjun Flour Mills v. State of Odisha [Civil Appeal No. 8763 of 1994], involving the constitutional validity of Section 5A of the Odisha Sales Tax Act, 1947, introduced in 1997. The provision prescribed an additional tax of 10% for dealers having annual turnover between ₹10 lakh and ₹1 crore and 15% for dealers whose annual turnover exceeded ₹1 crore. The principal issue was whether such an additional levy could validly be imposed by State Legislatures or whether it encroached upon the Union Government’s exclusive power to levy income tax.
Earlier Supreme Court Judgments Examined
While examining the constitutional reference made in 1999, the Constitution Bench considered the principles laid down in Hoechst Pharmaceuticals Ltd. v. State of Bihar, S. Kodar v. State of Kerala and India Cement Ltd. v. State of Tamil Nadu. The Court clarified that the observations in India Cement, concerning a cess on mining royalty, did not establish that a levy calculated as a percentage of another tax was necessarily beyond legislative competence. The relevant premise concerning royalty in India Cement had subsequently been overruled by a larger Bench in Mineral Area Development Authority. Consequently, no surviving conflict of judicial precedents required determination by the Seven-Judge Bench.
GST Implementation Renders 27-Year-Old Reference Academic
The Supreme Court further observed that the constitutional framework and State enactments governing the disputed levies had undergone substantial changes following the introduction of GST in 2017. Since the earlier statutory provisions and constitutional framework had been substituted or replaced, the referred question no longer possessed prospective significance warranting adjudication by a Seven-Judge Constitution Bench. Accordingly, the Court declared the constitutional reference academic and infructuous.
Justice K.V. Viswanathan Reaffirms Validity of Additional Sales Tax
In a separate opinion, Hon’ble Justice K.V. Viswanathan reaffirmed that the earlier ruling in S. Kodar was correctly decided and continues to remain good law. His Lordship clarified that additional sales tax determined with reference to the sales tax payable by dealers exceeding a prescribed turnover threshold, where the levy is not passed on to consumers, falls within the State’s legislative competence under the then Entry 54 of List II and cannot be characterised as an unconstitutional tax on dealers’ income.
Pending Assessment Disputes and Punjab-Specific Issues Remain Open
Importantly, the Supreme Court did not conclusively determine all pending disputes arising under the erstwhile sales tax laws. The Court specifically left open questions relating to the validity of surcharge imposed upon otherwise exempted industrial units under the Punjab General Sales Tax Act, 1948, and whether cess proceeds under the Punjab Social Security Act, 2000, could be credited directly to the Punjab Social Security Fund without first being credited to the Consolidated Fund of the State under Article 266 of the Constitution.
The Court also left open the parties’ contentions concerning assessments and consequential reliefs in individual matters. The Supreme Court Registry was directed to place the lead case and connected matters before the appropriate regular Bench for disposal in accordance with the observations made by the Constitution Bench.
Significance of the Supreme Court Ruling
The decision provides important constitutional clarity regarding the nature and legislative competence of additional sales tax and surcharge imposed under the erstwhile State sales tax framework. While reaffirming the principle that an additional levy calculated on sales tax may retain the character of sales tax, the Supreme Court has recognised that the introduction of GST has substantially changed India’s indirect taxation framework.
The ruling is particularly relevant for pending legacy sales tax assessments, surcharge disputes, constitutional challenges and consequential refund or relief proceedings, which will continue to be governed by the applicable statutory provisions and judicial findings in individual cases.
Key Takeaway: The Supreme Court has reaffirmed the constitutional principle supporting States’ competence to impose additional sales tax under the erstwhile legal framework, while declaring the 27-year-old constitutional reference infructuous in view of GST implementation. The judgment does not introduce any new levy or compliance requirement under the present GST regime.
