What is "wrongful gain" as defined under the Indian Penal Code?

The Statutory Definition: Section 23 IPC and Sections 236–238 BNS

Section 23 of the Indian Penal Code, 1860 defined both wrongful gain and wrongful loss within a single, elegantly compact provision:

"Wrongful gain is gain by unlawful means of property to which the person gaining is not legally entitled. Wrongful loss is the loss by unlawful means of property to which the person losing it is legally entitled."

The section then proceeded to explain the scope of gaining and losing wrongfully:

"A person is said to gain wrongfully when such person retains wrongfully, as well as when such person acquires wrongfully. A person is said to lose wrongfully when such person is wrongfully kept out of any property, as well as when such person is wrongfully deprived of property."

The Bharatiya Nyaya Sanhita, 2023 has retained the substance of this definition entirely unchanged, but with a structural refinement. What was a single section under the IPC has been split into three provisions — Section 236 defining wrongful gain, Section 237 defining wrongful loss, and Section 238 dealing with gaining and losing wrongfully. As the Ratanlal & Dhirajlal commentary on the BNS records: "There are no material changes in the verbatim of the provision which affects the operation of the definition." The legislature, in creating the BNS, clearly regarded the formulation bequeathed by the original codifiers as sufficiently precise to survive intact into modern criminal law.

Unpacking the Definition: Three Essential Elements

The definition of wrongful gain contains within it three irreducible elements that must be understood in relation to each other.

First, there must be a gain. This means acquisition or retention of property. The word "property" here is significant — the gain must relate to property of a tangible character, not merely an abstract advantage. Fees payable to a college for attending lectures, as old case law confirms, constitute "property" within the meaning of the section. The gain, importantly, need not be permanent. This was decisively settled by the Supreme Court in KN Mehra v. State of Rajasthan (AIR 1957 SC 369), where the Court held: "The gain or loss contemplated need not be a total acquisition or a total deprivation but it is enough if it is a temporary retention of property by the person wrongfully gaining or a temporary keeping out of property from the person legally entitled." This ruling drew a deliberate contrast with the English law of larceny, under which only permanent deprivation was recognised as a criminal taking. Indian law chose a wider path.

Second, the gain must be by unlawful means. The word "wrongful" in the section means, as commentators have consistently explained, prejudicially affecting a party in some legal right. Unlawfulness, in this context, means not justified by law — either because the act is illegal in the sense of being punishable, or because it is unenforceable. The crucial point is this: if the means are lawful, there is no wrongful gain, no matter how much another person may suffer financially. Where municipal officers demolished an unauthorised construction under statutory authority, the courts consistently held that there was no wrongful loss to the complainant, since the act was lawful and done in exercise of powers under the Maharashtra Municipalities Act — the demolition was legal, not criminal.

Third, the gain must relate to property to which the person gaining is not legally entitled. This requirement brings into play the distinction between legal entitlement and factual possession. A person who forces his way into possession of property he genuinely believes to be his own, even if his claim is legally incorrect, may escape the label of wrongful gain if he acts in honest belief — because the element of acting by "unlawful means" with knowledge of illegality would be absent. However, if a person takes property knowing he has no legal right to it, the element is satisfied even if he gains only temporarily.

Gaining Wrongfully and Losing Wrongfully: Two Modes of Each

Section 23 IPC — now mirrored in Sections 236 to 238 BNS — carefully provides that wrongful gain is not limited to outright acquisition. It includes retention. A person who comes into possession of property lawfully but then retains it beyond his authority also gains wrongfully. The case of a postman who signs a postal receipt in the name of the addressee and retains the parcel for himself — accepted as wrongful gain in decided cases — illustrates this perfectly. His initial taking may have been part of his duty, but his retention was entirely unauthorised, making it wrongful gain.

Equally, wrongful loss is not limited to outright deprivation. It includes being kept out of property. If a creditor forcibly seizes a debtor's goods against the debtor's will to put pressure on him to pay, the debtor suffers wrongful loss even though the debtor may owe the creditor money — because the act of forcible seizure is not a mode of enforcement recognised by law. The Calcutta Full Bench recorded this principle clearly in Sri Churn Chungo (1895) 22 Cal 1017.

The Vital Link to Dishonesty: Section 24 IPC and Section 27 BNS

No discussion of wrongful gain is complete without examining its intimate connection with the concept of "dishonestly." Section 24 IPC (now Section 27 BNS) defines dishonestly as: "Whoever does anything with the intention of causing wrongful gain to one person or wrongful loss to another person, is said to do that thing dishonestly."

This is a definition of profound importance. It means that dishonesty under Indian criminal law is not a general moral state of deceptiveness or bad character. It is an entirely specific, legally defined state of mind — the intention to cause wrongful gain or wrongful loss. A person can be the most immoral of individuals, yet if his act does not carry the intention of causing wrongful gain or loss within the meaning of Section 23, he does not act dishonestly in the eyes of the IPC. Conversely, a person may appear outwardly respectful and polite but act dishonestly the moment his purpose is to cause wrongful gain to himself or another at another's expense. As the Supreme Court stated in S. Dutt v. State of UP (AIR 1966 SC 523), a person who does anything with the intention to cause wrongful gain to one person or wrongful loss to another is said to do that dishonestly.

Importantly, it is not necessary that both wrongful gain to one person and wrongful loss to another must be shown. A Full Bench of the Madras High Court settled this in Kotamraju Venkatrayadu v. Emperor (ILR 1905 28 Mad 90), holding that a person does a thing dishonestly if done with the intention of causing wrongful gain or loss — it is not necessary that there should be any intention to cause both.

The Aircraft Theft Case: A Landmark Illustration

No case better illustrates how these principles operate together than KN Mehra v. State of Rajasthan (AIR 1957 SC 369). Mehra and Phillips, cadets at the Indian Air Force Academy in Jodhpur, took off unauthorisedly in a Harvard aircraft on 14 May 1952 — before the prescribed time, without authorisation, without following any of the required formalities — and flew the aircraft to Pakistan. They were arrested on their return and prosecuted for theft under Section 379 IPC.

The defence argued, ingeniously, that since the aircraft had been returned and since no permanent deprivation was intended, neither wrongful gain nor wrongful loss had occurred. The Supreme Court rejected this entirely. It held that the temporary use of the aircraft had given the cadets the aircraft for their own purpose, and had temporarily deprived the Government of India of its legitimate use of that particular aircraft for the Indian Air Force on that day. Such use being unauthorised and against all regulations was clearly a gain or loss by unlawful means within Section 23. The fact that they eventually returned it did not undo the criminality of the temporary deprivation. This case is now among the most cited authorities for the proposition that temporary wrongful gain or loss is sufficient under Indian law.

An Illustration to Crystallise the Concept

Consider a simple illustration to anchor these principles. A and B are joint owners of a horse. A takes the horse from B's possession without B's knowledge, uses it for his own purposes for two days, and then returns it. Illustration (g) of Section 425 IPC itself provides a variation of this: "A, having joint property with Z in a horse, shoots the horse, intending thereby to cause wrongful loss to Z. A has committed mischief." But in our scenario, even if A merely takes and uses the horse without shooting it, he causes wrongful gain to himself (temporary use of property to which he had no exclusive entitlement against B's concurrent rights) and wrongful loss to B (who was kept out of property to which he was legally entitled). A acts with dishonest intention under Section 24. Whether his act constitutes theft or criminal misappropriation would depend on additional facts, but the foundational element of wrongful gain and wrongful loss is established beyond doubt.

Wrongful Gain and Its Role Across Offences

The significance of this definition reverberates across the IPC and BNS. Theft under Section 378 IPC (Section 303 BNS) requires that the taking be dishonest — which, by Section 24, means with intent to cause wrongful gain or loss. Cheating under Section 415 IPC (Section 318 BNS) requires fraudulent or dishonest inducement. Criminal misappropriation under Section 403 IPC (Section 314 BNS) requires dishonest misappropriation. Mischief under Section 425 IPC (Section 324 BNS) requires intent to cause wrongful loss or damage. In each case, the chain of reasoning ultimately leads back to Sections 23 and 24 IPC — or Sections 236 to 238 and 27 BNS — as the fountainhead.
