The Supreme Court analyzed the taxability of a non-compete fee in the case of Shiv Raj Gupta v. Commissioner of Income-Tax, concluding that the INR 6.6 crore received as a non-compete fee was not taxable under Section 28(ii)(a). The court emphasized that the non-compete fee was a capital receipt rather than a revenue receipt, and the assessment of competition and business value must consider actual commercial realities. The ruling reversed lower court decisions, reinforcing that any taxation must follow properly formulated substantial questions of law.
