Distinction — Tort vs Crime, Tort vs Breach of Contract, Tort vs Quasi-Contract

A tort is a civil wrong; that much is settled. But within the family of legal wrongs three other species sit close enough to a tort to be confused with it — the crime, the breach of contract, and the obligation arising from quasi-contract. Each is grounded in a different source of legal duty, owes that duty to a different class of persons, and is redressed by a different kind of remedy. Drawing the line between tort and these three cognate categories is the working content of this chapter, and it is the most heavily examined material in the introductory weeks of any judiciary syllabus.

The line-drawing matters because the same fact-pattern can simultaneously generate liability in two or more of these categories. A negligent driver injures a railway passenger — there is breach of the contract of safe carriage, and there is also the tort of negligence as worked out in Donoghue v. Stevenson. A bailee starves the bailor's horse — there is breach of the contract of bailment, and there is also the tort of negligence. A defendant digs a ditch on a public road — there is the criminal offence of public nuisance and the tort of private nuisance against any user injured by it. The remedies are concurrent and the plaintiff must elect, but he cannot recover the same loss twice. Knowing where one species ends and the next begins is therefore not academic; it determines which court hears the case, which limitation rule applies, what evidence is admissible, and how the measure of damages is computed.

The three working tests

Three diagnostic questions, asked in order, separate tort from each of its cognates.

1. Source of the duty. Was the duty imposed by general law on every member of society, or was it undertaken voluntarily by the defendant in an agreement, or held by him as a trustee, or imposed by law to prevent unjust enrichment? Tort duties are imposed by general law and owed to persons generally.
2. Person to whom the duty is owed. Is the duty a right in rem (good against the world) or a right in personam (good only against an identified counterparty)? Tort duties are in rem; contract duties are in personam; quasi-contract duties are owed to the specific person from whom the unjust benefit flowed.
3. Nature and measure of the remedy. Is the remedy unliquidated damages assessed by the court, or liquidated damages pre-fixed by the parties, or restitution of a specific sum, or punishment imposed by the State? Tort yields unliquidated damages; contract may yield liquidated; quasi-contract yields restitution; crime yields punishment.

These three tests, applied together, classify nearly every fact-pattern. The rest of this chapter works through each cognate category in turn — first crime, then breach of contract, then breach of trust, then quasi-contract — and lays out the doctrinal points and the leading authorities that the examiner returns to repeatedly. The threshold definitions on which all three tests rest are worked out in the introductory chapter on the definition, nature and scope of the law of torts; this chapter assumes them.

Tort and crime distinguished

Blackstone's classical division — repeated in every Indian textbook and worth memorising — is that wrongs are of two species: private wrongs, the infringement of private or civil rights belonging to individuals, redressed by civil action; and public wrongs, the breach of public rights and duties affecting the whole community, redressed by criminal prosecution. Tort is the leading example of the first; crime is the leading example of the second. The classification rests on a value judgment about the seriousness and reach of the wrong, not on its inner moral quality.

Five working differences

(i) Nature of the wrong. The wrongs that the law treats as comparatively less serious, or as affecting only the immediate sufferer, are placed under tort; those treated as serious or affecting the public are placed under crime. The same conduct can occupy both fields. Assault, defamation, negligence, conspiracy and nuisance are simultaneously tortious wrongs and statutory offences. The definition of any one of these wrongs may differ as between the civil and the criminal head — for instance, in defamation, truth alone is a complete defence in tort, but truth must be coupled with public good to operate as a defence to the offence under what was earlier Section 499 of the IPC and is now Section 356 of the Bharatiya Nyaya Sanhita, 2023. Where the obstruction outside a residential building is a tort of private nuisance, the same obstruction in the middle of a public road is the offence of public nuisance under Section 268 IPC (now Section 270 BNS).

(ii) Who sues. In tort, the injured party files the suit as plaintiff; if she chooses to compromise with the tortfeasor and withdraw, she is at liberty to do so. In crime, the proceeding is brought by the State even though the immediate sufferer is an individual; the offence is treated as a wrong against the public at large and, save in the closed list of compoundable offences, the parties cannot lawfully settle it. The civil suit is the property of the plaintiff; the prosecution is the property of the State.

(iii) The remedy. The civil court awards damages — that is, money compensation calibrated to the loss suffered. The criminal court awards punishment — imprisonment, fine, or both — calibrated to the wrong done and aimed at deterrence and protection of society. Compensation in the criminal track is exceptional; it is available under what was Section 357 of the old Cr.P.C. (and is now Section 396 of the Bharatiya Nagarik Suraksha Sanhita, 2023) when the criminal court orders payment to the injured party out of the fine imposed. That sum, however, does not displace the parallel civil action; the civil court will only credit the amount already paid against any subsequent damages award.

(iv) The function of detention. Imprisonment under criminal law is itself the punishment. Arrest and detention in civil execution exist for the limited purpose of compelling the judgment-debtor to perform a duty he has refused to perform; once the duty is performed, the detention ends, even before the term fixed expires. The criminal sanction looks backward at the wrong done; the civil sanction looks forward to the duty unperformed.

(v) Concurrent remedies. The civil and criminal remedies are concurrent, not alternative. Campbell v. Paddington Corporation [1911] 1 K.B. 869 illustrates: the digging of a ditch on a public road simultaneously generated the offence of public nuisance and the tort of private nuisance against an injured passer-by. The defendant could be punished and required to pay damages.

Working table — tort and crime

The points above can be set out in tabular form for revision.

• Source of duty. Tort: imposed by general law. Crime: imposed by penal statute, in India principally the BNS (previously the IPC) and the special criminal statutes.
• Who sues. Tort: the injured plaintiff. Crime: the State.
• Settlement. Tort: freely settleable. Crime: not settleable except in the listed compoundable offences.
• Remedy. Tort: unliquidated damages, occasionally injunction or specific restitution. Crime: imprisonment, fine, or both.
• Standard of proof. Tort: balance of probabilities. Crime: beyond reasonable doubt.
• Mens rea. Tort: required for some heads (deceit, malicious prosecution, conspiracy), irrelevant for others (conversion, strict liability). Crime: ordinarily required, with the closed list of strict-liability statutory offences as the exception.

For the substantive content of the criminal law that interacts with these distinctions, see the IPC and BNS notes hub; the precise tort meaning of intent and recklessness is taken up in our chapter on mental elements in tort. For the constitutional dimension — when an act of the State is both a tort and a violation of a fundamental right — see the chapter on the vicarious liability of the State.

Tort and breach of contract distinguished

The breach-of-contract action and the tort action share a common remedy — money damages — but separate cleanly on the three diagnostic questions.

(i) Source of the duty. A breach of contract results from the breach of a duty that the parties themselves undertook by agreement. A tort results from the breach of a duty imposed on every member of the society by the general law. The tort duty not to assault, not to defame, not to commit nuisance or trespass is owed by everyone irrespective of any agreement; the contract duty arises only because the contracting party voluntarily assumed it. Treitel's framing — that contract law enforces promises while tort law enforces obligations — captures the same point.

(ii) Person to whom the duty is owed. In contract, the duty is grounded in the privity of the contract; each contracting party owes a duty only to the other contracting party. The classical articulation is Tweddle v. Atkinson (1861) 1 B. & S. 393 — a stranger to the contract cannot sue. The tort duty is owed to persons generally; whoever in fact suffers the breach can sue, even though he is a stranger to any antecedent agreement. Donoghue v. Stevenson [1932] A.C. 562 buried the privity-fallacy that had been imported into tort by Winterbottom v. Wright (1842) 10 M. & W. 109 — the manufacturer of an opaque, sealed bottle of ginger-beer was held to owe a duty of care to the ultimate consumer although his only contract was with the retailer. Lord Macmillan's reasoning makes the doctrinal move explicit: the existence of a contractual relationship between A and B does not exclude the co-existence of a parallel tort duty owed by A to C.

The Indian application is on all fours. In Klaus Mittelbachert v. East India Hotels Ltd., A.I.R. 1997 Del. 201, a Lufthansa co-pilot — a stranger to the contract between his employer and the Hotel Oberoi Inter-Continental — was injured by the defective design of the hotel swimming pool. The Delhi High Court held that the privity-of-contract objection was irrelevant to a tort action; the hotel owed a duty of care directly to the plaintiff and was liable in negligence. Exemplary damages of Rs. 50 lakh were awarded.

(iii) Measure of damages. Damages in contract may be liquidated; damages in tort are always unliquidated. Liquidated damages are sums pre-agreed by the parties as a genuine pre-estimate of the loss the breach will cause. In tort the parties are typically strangers until the wrong occurs, so no antecedent agreement is possible and the quantum is necessarily a judicial estimate at the time of judgment. The heads of damages in tort — general, special, nominal and exemplary — track this difference.

(iv) Concurrent liability. The same fact can be both a breach of contract and a tort. Sheikh Mahomed v. The British Indian Steam Navigation Co. Ltd. (1908) 32 Mad. 95 is the classical Indian authority — a railway passenger injured by the negligent driving of the company's servant could sue for breach of the contract of safe carriage or for the tort of negligence. The plaintiff cannot recover the same loss twice; he must elect.

The privity-of-contract fallacy and its end

The point deserves separate treatment because the examiner returns to it. Winterbottom v. Wright (1842) had been read as laying down that where A's act amounts to both breach of his contract with B and a tort against C, C must show privity of contract before he can sue in tort. That reading is wrong, but it operated as the orthodox position for ninety years. Donoghue v. Stevenson ended it. The tort action is independent of any contract; the privity rule belongs to contract law and has no business in tort. The Indian cases — Klaus Mittelbachert, the line of consumer-protection decisions, the absolute-liability cases — all rest on the post-1932 settlement.

Tort and breach of trust distinguished

The breach-of-trust action sits closer to tort than the contract action, in that the duty is imposed by law (on the trustee, the moment the trust is constituted) rather than freely assumed by agreement. The two diverge, however, on the remedy and on the historical jurisdiction.

In a breach of trust, the beneficiary's claim is for compensation calculated on the loss the trust property has suffered. The amount is ascertainable before the action is brought — it is the diminution in the trust corpus or the profit improperly diverted — and the damages are therefore liquidated. Damages in tort are unliquidated; the court fixes the sum at the time of judgment. Historically the difference is jurisdictional. The law of torts grew in the common-law courts; the breach of trust was redressed in the Court of Chancery, which administered the equitable jurisdiction. Salmond's preferred formulation is that the law of trusts is best treated as a detachable branch of the law of property rather than as a fellow-traveller of tort.

Tort and quasi-contract distinguished

Quasi-contract is the law's response to the unjust enrichment of one party at the expense of another. Where A leaves goods at B's house by mistake and B treats them as his own, B is bound to pay A their value; where A and B jointly owe Rs. 100 to C and A pays the whole amount, B remaining ignorant and paying again, C is bound to refund the duplication to B. The duty in each case is imposed by law to prevent the unjust retention of money that in justice belongs to the other party. Indian quasi-contract is statutorily organised in Sections 68 to 72 of the Indian Contract Act, 1872, although the underlying principle is judge-made and ancestral.

The common ground with tort is that in each case the duty is imposed by law and not freely assumed. The differences are three.

1. Subject-matter of the remedy. The quasi-contract remedy lies only with respect to money, and ordinarily for a liquidated sum equal to the unjust benefit. Tort remedies are not so confined — damages are typical, but injunctions, specific restitution, abatement and self-help are also available; and the damages, when awarded, are unliquidated.
2. Person to whom the duty is owed. In quasi-contract the duty is always owed to the specific person from whom the benefit unjustly flowed. In tort the duty is owed to persons generally; only that person who suffers the breach can sue, but the duty itself is universal.
3. The waiver of tort. Where the defendant has gained a profit by his tort, the plaintiff can sometimes waive the tort and sue in quasi-contract for money equivalent to the unjust benefit. The torts that may be so waived are conversion, trespass to land or goods, deceit and the action for extorting money by threats; defamation and assault cannot be waived. The leading authority is United Australia Ltd. v. Barclays Bank Ltd. [1941] A.C. 1, where the House of Lords clarified that the election between tort and quasi-contract does not extinguish the underlying tort but only forecloses the second action for the same wrong.

Why the same fact-pattern can yield more than one cause of action

It is worth pausing on the structural reason that overlapping liability is so common. The four categories — tort, crime, contract, quasi-contract — are not carved out of mutually exclusive subject-matter; they are different responses to different aspects of the same factual event. A single act of negligent driving causes a road accident — the State's response is the prosecution for rash and negligent driving (criminal); the passenger's response is the tort suit for personal injury (tort); his contract for safe carriage with the railway company is broken (contract); and if the driver had collected a fare without the authority of the railway, the company's claim against him for that money would lie in quasi-contract. Each branch of the law is asking a different question of the same facts. The bar against double recovery — most clearly stated in United Australia Ltd. v. Barclays Bank — sees to it that the plaintiff is not over-compensated, but it does not foreclose the multiplicity of causes. The joint and several liability rule operates inside the tort track to allocate the same loss across multiple wrongdoers without multiplying the recovery.

The exam-relevant consequence is this: where a fact pattern includes a contract, the candidate must always ask whether a parallel tort duty exists, whether the criminal statute has been engaged, and whether any benefit has flowed which the law would refuse to leave with the defendant. The introductory chapters on essentials of a tort and on the two foundational maxims supply the threshold tests for the tort enquiry; the present chapter supplies the apparatus for sorting tort from its civil and criminal cognates.

Indian-law features that bear on the distinction

Three Indian-specific features adjust the textbook English distinctions and are commonly tested.

The constitutional tort. Beginning with Rudul Sah v. State of Bihar, A.I.R. 1983 S.C. 1086, the Supreme Court has awarded compensation for violation of fundamental rights in proceedings under Articles 32 and 226. The remedy is not, strictly, a tort action — it is a public-law remedy — but in practice it overlaps with the tort suit against the State and competes with it. Bhim Singh v. State of J. & K., A.I.R. 1986 S.C. 494, is the line's other anchor. The constitutional-tort track is faster, free of the sovereign-immunity arguments inherited from the Government of India Act jurisprudence, and pleaded directly under Articles 32 or 226.

Statutory codification of discrete pockets. Indian tort law remains overwhelmingly judge-made, but the legislature has codified pockets of it. The Consumer Protection Act, 2019, the Motor Vehicles Act, 1988 (with no-fault and structured-formula compensation), the Public Liability Insurance Act, 1991, the Workmen's Compensation Act, 1923 (now the Employees' Compensation Act) and the criminal-court compensation jurisdiction under Section 396 BNSS each carve out a part of the common-law field and replace the case-by-case enquiry with a statutory remedy. The interaction with the surviving common-law action is a routine examination question.

The absolute-liability doctrine. The Supreme Court's creation of absolute liability in M.C. Mehta v. Union of India, A.I.R. 1987 S.C. 1086, displaces the Rylands v. Fletcher exceptions for hazardous and inherently dangerous industries. The strict-liability/absolute-liability distinction does not cut tort off from contract or crime, but it changes the contour of the tort enquiry itself. The detailed treatment is in our chapter on strict liability under the Rylands v. Fletcher rule.

Summary table — tort against its three cognates

For revision, the four-way classification can be reduced to a single table.

• Tort. Duty imposed by general law. Owed to persons generally. Remedy: unliquidated damages, sometimes injunction or specific restitution. Plaintiff: the injured party.
• Crime. Duty imposed by penal statute. Owed to the State (the public). Remedy: imprisonment and/or fine. Prosecutor: the State.
• Breach of contract. Duty assumed by agreement. Owed only to the contracting counterparty. Remedy: damages (often liquidated), specific performance, rescission. Plaintiff: the contracting party.
• Breach of trust. Duty imposed by equity on the trustee. Owed to the beneficiary. Remedy: liquidated damages, account of profits, restoration of trust property. Plaintiff: the beneficiary.
• Quasi-contract. Duty imposed by law to prevent unjust enrichment. Owed to the specific person from whom the benefit flowed. Remedy: refund of the unjust benefit (typically liquidated). Plaintiff: the person from whom the benefit was taken.

Putting the five rows side by side captures, in compact form, the doctrinal apparatus that this chapter has developed. Every later chapter on the hub assumes this classification — see in particular the Law of Torts notes hub — and the candidate who does not master it now will lose marks in every later applied fact-pattern problem. The two-step exam discipline is fixed: first classify the duty, then choose the remedy. The classification is the work of this chapter; the remedy follows from it.

Frequently asked questions

If the same act is both a tort and a crime, can the defendant be punished and asked to pay damages?

Yes. The civil and criminal remedies are concurrent, not alternative. Campbell v. Paddington Corporation (1911) is the standard illustration — the same ditch on a public road grounded both the offence of public nuisance and the tort of private nuisance against an injured passer-by. The criminal court can also award limited compensation under Section 396 BNSS (previously Section 357 Cr.P.C.), but that does not displace the civil suit. If a civil suit is later filed for the same loss, the civil court will credit any sum already paid under the criminal compensation jurisdiction against the damages award.

Is privity of contract necessary to sue in tort where a contract is in the background?

No. The privity-of-contract requirement belongs to contract law, not tort. Donoghue v. Stevenson (1932) buried the contrary position taken in Winterbottom v. Wright (1842). The manufacturer of a sealed product owes a duty of care to the ultimate consumer though his only contract was with the retailer. The Indian application is on all fours — Klaus Mittelbachert v. East India Hotels (1997) allowed a stranger to the contract between his employer and the hotel to sue the hotel directly in tort for personal injury caused by the defective design of the hotel swimming pool.

How are damages in tort different from damages in contract?

Damages in tort are always unliquidated — the court fixes the sum at the time of judgment in the light of the harm proved. Damages in contract may be liquidated, that is, pre-fixed by the parties as a genuine pre-estimate of the loss the breach will cause. The structural reason is that the parties to a tort are typically strangers until the wrong occurs, so no antecedent agreement is possible. The four heads of tort damages — general, special, nominal and exemplary — track this contrast.

What is the waiver of tort and which torts can be waived?

Where the defendant has gained a profit by his tort, the plaintiff may waive the tort and sue in quasi-contract for money equivalent to the unjust benefit. The torts that may be waived in this way are conversion, trespass to land or goods, deceit and the action for extorting money by threats. Defamation and assault cannot be waived — there is no benefit to extract. The leading authority is United Australia Ltd. v. Barclays Bank Ltd. (1941), where the House of Lords clarified that the election does not extinguish the underlying tort but forecloses a second action for the same wrong.

Why is breach of trust treated as a separate civil wrong from tort?

The substantive reason is that damages in trust are liquidated — they are calculated on the diminution in the trust corpus or the profit improperly diverted, and are ascertainable before suit. Damages in tort are unliquidated. The historical reason is jurisdictional — the law of torts grew in the common-law courts, whereas the breach of trust was redressed in the Court of Chancery under its equitable jurisdiction. Salmond suggests that the law of trusts is best classified as a branch of the law of property rather than as a sibling of tort.

What is the difference between tort and quasi-contract on the duty owed?

In quasi-contract the duty is always owed to a specific person — the one from whom the unjust benefit flowed. In tort the duty is owed to persons generally; whoever in fact suffers the breach can sue, but the underlying duty is universal. The remedy also differs in subject-matter — quasi-contract gives only money, and ordinarily a liquidated sum equal to the unjust benefit, whereas tort gives unliquidated damages and may also yield an injunction, specific restitution, abatement of nuisance, or self-help.
