C.I.T. v. G.R. Karthikeyan (1993)

The first thing this paper asks you to do is to say what income means, and the Act refuses to tell you. Section 2(49) opens with the words income includes and then lists. An inclusive definition settles that the listed things are income; it settles nothing about anything else. So when a receipt is not squarely inside a sub-clause — a prize, a windfall, a benefit in kind — you need a method rather than a list.

Karthikeyan supplies the method, and it supplies the constitutional reason the method is right. It is the case to open with on any question asking how wide the word income is, and the case that makes the four older authorities on the width of the word usable, because it collects them.

The assessment year was 1974-75. The assessee, assessed as an individual, had income from several sources including salary and business. During the relevant accounting year he took part in the All India Highway Motor Rally, organised jointly by the Automobile Association of Eastern India and the Indian Oil Corporation and supported by several regional automobile associations and the federations of Indian motor sports clubs and automobile associations.

The rally was restricted to private motor cars. Its route ran approximately 6,956 kilometres; a competitor could start from Delhi, Calcutta, Madras or Bombay, proceed anti-clockwise and return to his starting point. It was designed to test endurance driving and the reliability of the automobiles, and competitors had to observe both the ordinary traffic regulations and the regulations prescribed by the Rally Committee. Prizes were awarded on overall classification.

The assessee was awarded a first prize of Rs 20,000 by the Indian Oil Corporation and a further Rs 2,000 by the All India Highway Motor Rally. The rally was found to be neither a race nor a game. On that footing the High Court held that winnings in the sub-clause meant money won by gambling or betting, so the prize was not income and Rs 22,000 was not taxable.

The Supreme Court reversed. The prize money was income and was chargeable.

Two propositions carry the decision. First, the ambit of the statutory definition of income "should be the same as that of the word income occurring in Entry 82 of List I of the Seventh Schedule to the Constitution (corresponding to Entry 54 of List I of the Seventh Schedule to the Government of India Act)". Second, the sub-clause on winnings is not confined to gambling: "All crossword puzzles are not of a gambling nature", and the words "other games of any sort" are "of wide amplitude".

The Court began from candour rather than from a formula: "It is not easy to define income." It then assembled the authorities that fix the width of the word.

• Lord Wright in Kamakshya Narayan Singh: income "is a word difficult and perhaps impossible to define in any precise general formula".
• The Privy Council in Gopal Saran Narain Singh: "anything that can properly be described as income is taxable under the Act unless expressly exempted".
• Navinchandra Mafatlal, where the natural meaning of income was "a thing that comes in", a meaning that "embraces any profit or gain which is actually received" — the decision that held a tax on capital gains to be a tax on income, and so still governs the width of Entry 82.
• Bhagwan Dass Jain, where the notional annual value of a self-occupied house was taxable, "affirming that the expression income is of the widest amplitude and that it includes not merely what is received or what comes in by exploiting the use of the property but also that which can be converted into income".

From these the Court drew the chain that a student should reproduce. The statutory word takes its width from the constitutional entry; the entry is read at its widest; therefore the statutory word is read at its widest; therefore an inclusive definition enlarges the ordinary meaning rather than confining it. Since the enlarged word covers anything that can properly be described as income, the argument that the prize fell outside the gambling sub-clause could not save it: the sub-clause was not a boundary but an illustration, and in any event its own language reached well beyond gambling.

It opens every question on the meaning, nature and scope of income, and every question on whether a particular receipt — a prize, an award, a windfall, a benefit — is taxable. The structure is: quote the opening words of s. 2(49), say the definition is inclusive, tie it to Entry 82 through Karthikeyan, and then apply the test.

The test to state and apply: if a receipt can properly be described as income, it is taxable unless it is expressly exempted. Put the burden where the case puts it — on the person claiming the exemption to find it in the Act.

It disposes of the argument that a receipt escapes tax merely because it does not fit neatly inside one of the enumerated sub-clauses, and the narrower argument that winnings means gambling winnings.

It does not decide that everything that comes in is income. A capital receipt, a receipt that never became the assessee's at all, and an expressly exempted receipt all remain outside. For the second of those, go to the diversion-by-overriding-title line; for the third, to the agricultural income cases, where the exemption exists because the Union's entry stops where the State's begins.

Sequence for the standard essay: Karthikeyan first, then Navinchandra Mafatlal, Kamakshya Narayan Singh, Gopal Saran Narain Singh and Bhagwan Dass Jain as the supporting line.

One caution on the text. The 1961 sub-clause that Karthikeyan construed ended with the word whatsoever; the corresponding clause of the 2025 Act omits it. The omission does not narrow the list, and the case continues to govern.
