CHOWGULE & CO. PVT. LTD. & ANR. vs UNION OF INDIA & OTHERS(AND VICE VERSA)

The Supreme Court examined whether the blending of ore during loading constituted 'manufacture or processing' under Section 8(3)(b) of the Central Sales Tax Act, 1956. The Court held that the entire process of mining, transporting, and blending ore is an integrated operation that qualifies for lower sales tax rates. The Court ruled in favor of the assessee, allowing the inclusion of additional items for tax exemption, thereby affirming the need for a broad interpretation of manufacturing processes in the context of sales tax.
