Case Note & Summary
The case involved an appeal against a judgment of the High Court of Judicature at Bombay regarding the validity of section 12-B of the Indian Income-tax Act, 1922, which imposed tax on capital gains. The appellant, Navinchandra Mafatlal, was assessed for the assessment year 1947-1948, including capital gains from the sale of immovable properties. The appellant contended that the tax was ultra vires the Central Legislature. The High Court dismissed the appeal, leading to the current appeal before the Supreme Court. The core legal issue was whether the tax on capital gains was valid under the legislative powers conferred by the Government of India Act, 1935. The Supreme Court analyzed the legislative entries and concluded that capital gains fell within the definition of income as per entry 54 of List I. The court emphasized that the interpretation of 'income' should be broad and inclusive, rejecting the argument that a clear distinction existed between income and capital gains based on legislative practice. The court upheld the validity of section 12-B, confirming that the tax on capital gains was intra vires. The appeal was dismissed with costs.
