As per case facts, the State of Gujarat appealed against a High Court judgment that upheld a Tribunal's decision, which allowed M/s. Ambuja Cement Ltd. to exclude Value Added Tax ... and the value of purchases on which no tax credit was claimed from their taxable turnover. The assessing officer had initially included these amounts, leading to the dispute, but the Tribunal disagreed. The question arose whether Value Added Tax and the value of purchases without tax credit should be excluded from the aggregate taxable turnover of purchases for reducing tax credit under Section 11(3)(b) of the Gujarat Value Added Tax Act, 2003, specifically concerning the definition of "Purchase Price" under sub-Section (18) of Section 2 of the GVAT Act. Finally, the Supreme Court, after analyzing the relevant sections of the GVAT Act, clarified that the definition of "purchase price" is exhaustive and enumerative, explicitly listing only duties under the Central Excise Tariff Act, 1983, and the Customs Act, 1962. Since Value Added Tax is not included in this specific list, the Court concluded that it must be excluded. Consequently, the Court ruled that Value Added Tax and the value of purchases on which no tax credit was claimed were correctly excluded from the Respondent dealer's total turnover for tax liability calculation under Section 11(3)(b) of the GVAT Act. The appeals by the State were dismissed, and the Transfer Cases were allowed, affirming the High Court's judgment.
