General Defences — Volenti Non Fit Injuria

When a person consents to the infliction of some harm upon himself, he has no remedy for it in tort. That is the maxim volenti non fit injuria — to one who is willing, no harm is done. The defence is the first of the general defences in the law of torts and the most heavily examined one. It looks deceptively simple, but its real difficulty lies in three places: distinguishing free consent from coerced consent, distinguishing mere knowledge of risk from assumption of risk, and identifying the situations where the defence does not apply at all — most notably in rescue cases and in master-servant relationships.

This chapter sets out the doctrine in full. After the conceptual frame, it works through the leading authorities — Hall v. Brooklands Auto Racing Club, Padmavati v. Dugganaika, Wooldridge v. Sumner, Thomas v. Quartermaine, Smith v. Baker, Bowater v. Rowley Regis Corporation, Imperial Chemical Industries v. Shatwell, Dann v. Hamilton and the rescue line beginning with Haynes v. Harwood. It closes by distinguishing volenti from the doctrine of contributory negligence, the comparison most often tested in judiciary papers.

The maxim and its rationale

The defence rests on the elementary principle that no man can enforce a right which he has voluntarily waived or abandoned: volenti non fit injuria. If the plaintiff voluntarily agrees to suffer some harm, he is not allowed to complain when that harm comes. The case of R. v. Donovan (1934) 2 KB 498 contains a classical statement of the principle. Consent operates as a complete defence — unlike contributory negligence, which since the Law Reform (Contributory Negligence) Act, 1945 in England and the corresponding Indian rule only reduces damages.

Consent may be express or implied. Express consent presents little doctrinal difficulty: when a patient submits to a surgical operation, when a guest is invited into the house, when a person agrees to the publication of a defamatory matter concerning himself (Chapman v. Lord Ellesmere (1932) 2 KB 431), there is no actionable wrong. Implied consent is harder, and is the staple of the case law. A player in cricket or football is taken to consent to any hurt likely in the normal course of the game; a person on a public highway is taken to consent to the risk of pure accidents (Holmes v. Mather (1875) LR 10 Ex 261); a spectator at a sporting event is taken to consent to the risks inherent in being a spectator. The chapter on the essentials of tort sets the maxim in its larger context.

Spectator and participant cases — implied consent

Hall v. Brooklands Auto Racing Club (1932) 1 KB 205 is the textbook case. The plaintiff was a spectator at a motor-car race held at Brooklands on a track owned by the defendant company. During the race two cars collided, and one was thrown among the spectators, injuring the plaintiff. The Court of Appeal held the defendants not liable: the plaintiff impliedly took the risk of such injury, the danger being inherent in the sport, and a danger any spectator could foresee.

Padmavati v. Dugganaika AIR 1975 Kant 184 is the leading Indian authority. While the driver was taking a jeep to fill petrol, two strangers took a lift in it. Suddenly one of the bolts fixing the right front wheel to the axle gave way, toppling the jeep; the strangers were thrown out and one died. It was held that neither the driver nor his master could be made liable: the case was one of sheer accident, and the strangers had voluntarily got into the jeep, so volenti applied.

Wooldridge v. Sumner (1963) 2 QB 43 is the case for participant-against-spectator. The plaintiff, a photographer, was at a horse show, standing at the boundary of the arena. One of the defendant's horses rounded the bend too fast; the plaintiff was startled, fell into the horse's course, and was seriously injured. The horse won the competition. The Court of Appeal held the defendants not liable. Diplock L.J. said: "the duty which he (the defendant) owes is a duty of care, not a duty of skill… A person attending a game or competition takes the risk of any damage caused to him by any act of a participant done in the course of and for the purpose of the game or competition notwithstanding that such act may involve an error of judgment or a lapse of skill, unless the participant's conduct is such as to evince a reckless disregard of the spectator's safety."

Thomas v. Quartermaine (1887) 18 QBD 685 is a closely allied authority on the workplace side. The plaintiff, an employee in the defendant's brewery, was trying to remove a lid from a boiling vat. The lid stuck; he gave it an extra pull; it came off suddenly and he fell back into a cooling vat containing scalding liquid. The majority of the Court of Appeal held the defendant not liable: the danger was visible and the plaintiff appreciated and voluntarily encountered the same.

Trespasser and dangerous-thing cases

The defence is also available against trespassers in some circumstances. In Illot v. Wilkes (1820) 3 B&Ald 304, a trespasser who knew about the presence of spring guns on the land could not recover damages when he was shot by one. Similarly, damage caused to a trespasser by broken glass or spikes on a wall, or a fierce dog (Sarch v. Blackburn (1830) 4 C&P 297), is not actionable. The position is, however, qualified by the rule in Bird v. Holbrook (1828) 4 Bing 628 — discussed in the chapter on the plaintiff as wrongdoer — where the trespasser had no notice and was held entitled to compensation. The distinguishing feature is whether the plaintiff knew of the danger and accepted it.

The consent must be free

For the defence to be available, the plaintiff's consent to the act done by the defendant must be free. Consent obtained by fraud, under compulsion, or under some mistaken impression does not serve as a good defence. The act done by the defendant must also be the same act for which consent was given: if a guest is requested to sit in the drawing room and instead enters the bedroom, the consent does not protect him from a trespass action; if a postman is impliedly licensed to deliver post up to the door and instead enters a private room, he is liable.

The Indian decision in Lakshmi Rajan v. Malar Hospital Ltd. (1998) CPJ 586 (NCDRC) makes the point sharply. The complainant, a married woman aged 40, noticed a painful lump in her breast. The lump had no effect on her uterus, but during surgery the uterus was removed without justification. The hospital was held liable for deficiency in service. The patient's consent to the breast operation did not imply consent to the removal of the uterus. The chapter on medical and professional negligence develops the consent rules in the medical setting.

Consent obtained by fraud

Consent obtained by fraud is not real and does not serve as a good defence. The Irish case of Hegarty v. Shine (1878) 4 LR Ir 288 has, however, held that mere concealment of facts may not be a fraud sufficient to vitiate consent — there the plaintiff's paramour had infected her with venereal disease and her action for assault failed partly on the ground of ex turpi causa non oritur actio. The criminal-law cases R. v. Williams (1923) 1 KB 340 and R. v. Clarence (1888) 22 QBD 23 illustrate the distinction: fraud vitiates consent if it induces a mistake as to the real nature of the act done, not as to its mere consequences.

Consent obtained under compulsion

Consent given under circumstances where the person does not have freedom of choice is not the proper consent. A man cannot be said to be truly willing unless he is in a position to choose freely; freedom of choice predicates not only full knowledge of the relevant circumstances but also the absence of any feeling of constraint. The situation arises chiefly in master-servant relationships. A servant faced with the choice of accepting risky work or losing his job, who accepts the risk, has not necessarily agreed to bear its consequences. There is no volenti non fit injuria where a servant is compelled to do work in spite of his protests, as Bowater v. Rowley Regis Corporation (1944) KB 476 held. But where a workman freely adopts a risky method of work without compulsion, the defence is available — Imperial Chemical Industries Ltd. v. Shatwell (1965) AC 656.

Mere knowledge does not imply assent — Smith v. Baker

The most important refinement of the maxim is that scienti non fit injuria is not the law: volenti non fit injuria is. For the defence to apply, two distinct points must be established:

1. The plaintiff knew that the risk was there.
2. He, knowing of it, agreed to suffer the harm.

Mere knowledge is not enough. Bowen L.J. observed in Thomas v. Quartermaine: the maxim is volenti, not scienti. Merely because the plaintiff knows of the harm does not imply that he assents to suffer it.

Bowater v. Rowley Regis Corporation illustrates the proposition. The plaintiff, a cart driver, was asked by the defendant's foreman to drive a horse which, to the knowledge of both, was liable to bolt. The plaintiff protested but ultimately took the horse out in obedience to the order. The horse bolted and the plaintiff was injured. The Court held that the maxim did not apply. Goddard L.J. said the maxim, in master-servant cases, must be applied with extreme caution; it can hardly ever apply where the act to which the servant is said to be volens arises out of his ordinary duty, unless the work itself is one in which danger is necessarily involved.

The leading authority is the House of Lords decision in Smith v. Baker & Sons (1891) AC 325. The plaintiff was a workman employed by the defendants on working a drill for the purpose of cutting a rock. By the help of a crane, stones were being conveyed from one side to the other; each time the crane passed over the plaintiff's head. While the plaintiff was busy with his work, a stone fell from the crane and injured him. The employers had been negligent in not warning him of the recurring danger, although the plaintiff was generally aware of the risk. The House of Lords held that as there was mere knowledge of risk without the assumption of it, the maxim did not apply, and the defendants were liable.

Lord Herschell said: "Where a person undertakes to do work which is intrinsically dangerous, notwithstanding that reasonable care has been taken to render it as little dangerous as possible, he no doubt voluntarily subjects himself to the risks inevitably accompanying it… but where… a risk to the employed, which may or may not result in injury, has been created or enhanced by the negligence of the employer, [I cannot say] that the mere continuance in service, with knowledge of the risk, preclude[s] the employed, if he suffers from such negligence, from recovering in respect of his employer's breach of duty." The proposition has been consistently reaffirmed.

Imperial Chemical Industries v. Shatwell stands at the other extreme. Two brothers, George and James Shatwell, were working in the defendant's quarry. They tried to test some detonators without taking the requisite precautions, in contravention both of statutory provisions and of the employer's orders. An explosion injured the plaintiff, George Shatwell. The House of Lords granted the defence of volenti non fit injuria: where the workmen freely chose to flout statute and orders, the maxim applied even in a master-servant context.

Drunken driver — Dann v. Hamilton

In Dann v. Hamilton (1939) 1 KB 509, a lady, knowing the driver of a car was drunk, chose to travel in it instead of taking an omnibus. Due to the driver's negligence an accident occurred, killing the driver and injuring the lady passenger. Asquith J. rejected the defence of volenti, holding the driver's degree of intoxication was not so extreme that taking a lift could be deemed acceptance of an obvious danger. He observed that the maxim might apply where the drunkenness was so glaring that to accept a lift was "like engaging in an intrinsically and obviously dangerous occupation, intermeddling with an unexploded bomb or walking on the edge of an unfenced cliff." The decision has been criticised on the ground that contributory negligence would in any event have been available — but Lord Asquith later explained that contributory negligence had not been pleaded.

Negligence of the defendant defeats consent

The act done must be the same act to which consent has been given. Where the plaintiff consents to take some risk, the presumption is that the defendant will not be negligent. If a player consents to the ordinary incidents of hockey, he has not consented to a deliberate or negligent strike outside the rules. If a patient submits to a surgical operation, he has consented to the inherent risks of competent surgery, not to the surgeon's negligence. Slater v. Clay Cross Co. Ltd. (1956) 2 QB 264 illustrates the principle: the plaintiff, struck by a train while walking through a tunnel which the company knew was used by the public, was held entitled to recover where the driver's negligence in failing to whistle and slow down had caused the accident. Denning L.J. said her knowledge of the danger was a factor in contributory negligence but was not a bar to the action.

Limitations on the doctrine

The scope of the defence has been curtailed in two principal ways: (i) by the rescue-cases exception, and (ii) by statutory provision such as the Unfair Contract Terms Act, 1977 in England.

Rescue cases — Haynes v. Harwood

Where the plaintiff voluntarily encounters a risk to rescue someone from imminent danger created by the defendant's wrongful act, the defence of volenti is not available. Haynes v. Harwood (1935) 1 KB 146 is the foundational authority. The defendants' servant left a two-horse van unattended in a busy street. A boy threw a stone at the horses; they bolted, creating grave danger to women and children. A police constable on duty at a nearby station saw what was happening, ran out, and managed to stop the horses, suffering serious personal injuries in the process. The defence of volenti was rejected and the defendants were held liable. Greer L.J. adopted the American rule: "the doctrine of the assumption of risk does not apply where the plaintiff has, under an exigency caused by the defendant's wrongful misconduct, consciously and deliberately faced a risk, even of death, to rescue another from imminent danger of personal injury or death."

The American authority Wagner v. International Railway 232 NY 176 (1921) provided the famous Cardozo dictum: "Danger invites rescue. The cry of distress is the summons to relief. The law does not ignore those reactions in tracing conduct to its consequences." In Baker v. T.E. Hopkins & Son (1959) 1 WLR 966, a doctor who entered a well to rescue two workmen overcome by petrol-pump fumes was overcome himself and died; the rescue exception applied and the employer was liable.

The principle has been extended by Hyett v. Great Western Railway Co. (1948) 1 KB 345 to the rescue of property; and to cases where the person rescued is the very person whose negligence created the danger. The right of the rescuer is independent of any right of the victim, and is not affected by defences the defendant might have against the victim — for example contributory negligence by the victim, or trespass.

Statutory limitation

The Unfair Contract Terms Act, 1977 (England) limits the right of a person to restrict or exclude liability for negligence by contract term or by notice. Section 2(1) bars exclusion of liability for death or personal injury resulting from negligence; Section 2(2) requires the test of reasonableness for other loss; Section 2(3) provides that a person's mere agreement to or awareness of an exclusion notice is not by itself to be taken as voluntary acceptance of any risk. The Indian position, while not identical, draws on the same policy: courts examine notices and agreements with care, and require something more than awareness before treating consent as freely given.

Volenti and contributory negligence distinguished

The distinction is the most heavily examined comparison in this area. It can be set out in three propositions:

1. Volenti is a complete defence. Once it succeeds, the action fails entirely. Contributory negligence — under the Law Reform (Contributory Negligence) Act, 1945 in England and the corresponding Indian rule — only reduces the damages in proportion to the plaintiff's own fault.
2. Volenti and contributory negligence rest on different mental states. In contributory negligence, both the plaintiff and the defendant are negligent; in volenti, the plaintiff may have exercised due care for his own safety, but agreed to take the risk that the defendant's act would cause him harm. Defendant's negligence may rule out volenti where, on the facts, the consent was to the ordinary risk and not to negligence — Slater v. Clay Cross Co.
3. Knowledge of the danger. In volenti, the plaintiff is aware of the nature and extent of the danger; in contributory negligence, the plaintiff may have been unaware of a danger he ought to have known about.

The chapter on contributory negligence and the last-opportunity rule develops the second defence in detail. The student should also read the chapter on inevitable accident, which is the next general defence in the standard sequence.

Application — exam technique

A volenti question typically presents a fact-pattern where the plaintiff has been injured in a context that suggests assumption of risk. The candidate's checklist:

1. Was the plaintiff's consent free, or vitiated by fraud, mistake or compulsion? Compulsion in master-servant cases is the most common trap (Bowater, Smith v. Baker).
2. Did the plaintiff's consent extend to the very act and the very risk that caused the harm? Surgery without authorisation (Lakshmi Rajan) and player-on-player deliberate injury fall outside the consent.
3. Was there mere knowledge of risk, or actual assumption of it? Smith v. Baker is the key authority for the distinction.
4. Did the defendant's negligence go beyond the risks consented to? Slater v. Clay Cross.
5. Is this a rescue case? Apply Haynes v. Harwood and the rescue exception.
6. If volenti fails, would the alternative apportionment defence reduce the damages on the principles discussed in contributory negligence cases? — relevant especially in motor-vehicle cases such as Dann v. Hamilton.

Summary

The maxim volenti non fit injuria is the first of the general defences. It bars the plaintiff who has freely consented to the risk that caused him harm. Its operation turns on three sharp distinctions: free consent versus coerced consent, knowledge of risk versus assumption of risk, and ordinary risk versus negligence beyond the ordinary risk. The leading authorities — Hall v. Brooklands, Padmavati v. Dugganaika, Wooldridge v. Sumner, Smith v. Baker, Bowater v. Rowley Regis, Imperial Chemical Industries v. Shatwell, Dann v. Hamilton and the rescue line led by Haynes v. Harwood — must be at instant recall for the exam-aspirant. The defence stands beside the doctrine of ex turpi causa, act of God, private defence and statutory authority, all treated in subsequent chapters of the law-of-torts series.

Frequently asked questions

What is the difference between volenti non fit injuria and scienti non fit injuria?

Scienti non fit injuria is not the law of torts. The defence is volenti, not scienti. Mere knowledge of a risk is not enough; the plaintiff must have agreed to bear the risk if it materialised. Smith v. Baker (1891) AC 325 is the leading authority. The plaintiff there knew that stones were being swung overhead but had not consented that any injury suffered should lie on himself. Lord Herschell distinguished between voluntary acceptance of risks intrinsic to the work and continuance in service in the face of risk created or enhanced by the employer's negligence.

Why does the defence of volenti rarely succeed in master-servant cases?

Because consent given under economic compulsion is not free consent. As Goddard L.J. observed in Bowater v. Rowley Regis Corporation, the maxim must be applied with extreme caution where the act to which the servant is said to be volens arises out of his ordinary duty. A workman who obeys a foreman's order under threat of losing his job has not freely chosen to bear the risk. The exception is Imperial Chemical Industries v. Shatwell, where the workmen flouted both statute and the employer's express orders — there the consent was their own free act, and the defence applied.

When does the rescue-cases exception apply?

When the plaintiff has voluntarily encountered a risk to rescue someone from imminent danger created by the defendant's wrongful act. Haynes v. Harwood (1935) 1 KB 146 is the foundational authority — a constable injured stopping bolted horses recovered against the negligent owner. The doctrine has been extended to rescue of property (Hyett v. Great Western Railway), to medical rescuers (Baker v. T.E. Hopkins), and to cases where the person rescued is himself the negligent party. The rescuer's right is independent and not subject to defences the defendant might have against the victim.

Was Padmavati v. Dugganaika decided on volenti or on inevitable accident?

On both grounds. The Karnataka High Court held that the strangers who took a lift in the jeep had voluntarily got into it, so volenti applied, and that in any event the failure of the wheel-bolt could not have been detected by periodical check-up, making the case one of sheer accident. The case is therefore a useful authority for two general defences at once. The chapter on inevitable accident develops the second branch of the reasoning.

Does consent to a surgery imply consent to any operation the surgeon thinks fit?

No. The act consented to must be the act done. In Lakshmi Rajan v. Malar Hospital Ltd. (1998) the patient consented to a breast surgery; the surgeons additionally removed her uterus, which was unrelated to the lump. The hospital was held liable for deficiency in service. Volenti operates only to the precise act and risk the plaintiff has accepted. A surgeon who exceeds the scope of consent commits a battery and a breach of duty; the negligent execution of consented surgery is also outside the consent and not protected.

How is volenti distinguished from contributory negligence?

Volenti is a complete defence; contributory negligence only reduces damages in proportion to the plaintiff's fault. In contributory negligence both parties are negligent; in volenti the plaintiff need not be negligent at all but has accepted the risk. Volenti requires actual knowledge and assumption of risk; contributory negligence may apply where the plaintiff was unaware of a risk he ought to have known about. Defendant's negligence beyond the ordinary risk consented to defeats volenti, as in Slater v. Clay Cross Co. (1956) 2 QB 264.
