BHAI JASPAL SINGH vs ASSISTANT COMMNR., COMMERCIAL TAXES &ORS

The Supreme Court addressed the interpretation of 'investment' under the West Bengal Sales Tax Act, specifically in relation to exemption notifications and interest on tax assessments. The Court held that the term 'investment' refers to the actual value of machinery after depreciation, not merely the acquisition cost. The Court upheld the High Court's decision, confirming that the assessee was not entitled to the claimed tax exemption due to non-fulfillment of conditions specified in the relevant notifications and rules, thereby affirming the tax assessments and interest levied under Section 10A of the Act, 1941 and Section 31 of the Act, 1994.
