Volenti Non Fit Injuria

As a crime is a wrongful act, which results from the breach of a duty recognized by criminal law, a breach of contract is a non-performance of a duty undertaken by the party to a contract. Similarly, a tort is a breach of duty recognized under the law of torts in Legal Studies.

What is Volenti Non-Fit Injuria?

When the plaintiff brings an action against the defendant for a particular tort, providing the existence of all the essentials of that tort, the defendant would be liable for the same, The defendant may, however, even in such a case, avoid his liability by taking the plea of some defence, There are some specific defences, which are peculiar to some particular wrongs, the volenti non fit injuria example is in an action for several wrongs. For example, the general defence of consent may be taken, whether the action is for Trespass to person and Trespass to Land, defamation, false imprisonment or some other wrong.

The literal meaning of the ‘Volenti non fit injuria’ means, “ to a willing person no injury is done”, When a person consents to the infliction of some harm upon himself, he has no remedy for that tort. In case, the plaintiff voluntarily agrees to suffer some harm, he is not allowed to complain about that and his consent serves as a good defence against him. No man enforces a right which he has voluntarily waived or abandoned. Consent to suffer the harm may be expressed or implied.

When you invite somebody to your house, you cannot sue him for trespass, nor can you sue the surgeon after submitting to a surgical operation because you have expressly consented to these acts. Similarly, no action for defamation can be brought by a person who agrees to the publication of a matter defamatory of himself.

Many a time, the consent may be implied or inferred from the conduct of the parties. For example, a player in the games of cricket or football is deemed to be agreeing to any hurt which may be likely in the normal course of the game.

For the defence of consent to be available, the act causing the harm must not go beyond the limit of what has been consented. A player in a game of hockey has no right of action if he is hit while the game is played. But if there is deliberate injury caused by another player, the defence of volenti cannot be pleaded. Similarly, if a surgeon negligently operates, he cannot avoid the liability by pleading the defence of consent.

In the case of Padmavati v, Dugganaika

In this case, while the driver was taking the jeep to fill the petrol in the tank, two strangers took a lift in the jeep. Suddenly one of the bots fixed the right front wheel to the axle way toppling the jeep. The two strangers were thrown out and sustained injuries, and one of them died as a consequence of the same.

It was held in this case that neither the driver nor his master could be made liable, firstly, because it was a case of a sheer accident and, secondly, the strangers had voluntarily got into the jeep and such, the principle of volenti non fit injuria applied to this case.

Essential conditions for Volenti Non Fit Injuria

Volenti non fit injuria means when a person consents to the infliction of harm upon himself, he has no remedy for that in tort. Here are the essential conditions for the remedy of volenti no fit injuria.

1.The consent of the person must be free

For the defence to be available, it is necessary to show that the plaintiff’s consent to the act done by the defendant was free. If the consent of the plaintiff has been obtained by fraud or under compulsion or some mistaken impression, such consent does not serve as a good defence. Moreover, the act done by the defendant must be the same for which the consent is given. Thus, if you invite some person to your house, you cannot sue him for trespass when he enters your premises. But, if the visitor goes to a place for which no consent is given, he will be liable for trespass. Similarly, a postman has the implied consent of the resident of a building to go up to a particular place to deliver a dak, For the entry up to that particular point, he cannot be made liable. If the postman goes beyond that limit and enters the rooms of the house he would be liable for the trespass.

In the case of Lakshmi Rajan v. Malar Hospital Ltd.

In this case, the complainant, a married woman, aged 40 years, noticed the development of a painful lump in her breast. The lump did not affect her uterus, but during surgery, her uterus was removed without any justification.

It was held in this case that the opposite party, i.e. the hospital was liable for deficiency in service. It was held that the patient’s consent for the operation did not imply her consent to the removal of the uterus.

2. Consent shouldn’t be obtained by fraud.

Consent obtained by fraud is not real and that does not serve as a good defence. In the Irish case of Hegarty v. Shine, it has, however, been heard that mere concealment of facts may be such a fraud as to vitiate consent. There, the plaintiff’s paramour had infected her with venereal disease and she, therefore, brought an action for assault. The action failed partly on the ground that mere non-disclosure of the disease by the plaintiff was not such a fraud as to vitiate consent, and partly on the ground ex turpi causa non oritur actio. In some criminal cases, it has been held that mere submission to an intercourse does not imply consent, if the submission had been procured by fraud which induced a mistake in the mind of the victim as to the real nature of the act done.

3. Consent obtained under compulsion

Consent given under circumstances when the person does not have freedom of choice is not the proper consent. A person may be compelled by some situation to knowingly undertake some risky work which, if he had a free choice, he would not have undertaken. That situation generally arises in a master-servant relationship. The servant may sometimes be faced with the situation of either accepting the risky work or losing the job. If he agrees to the first alternative, it does not necessarily imply that he has agreed to suffer the consequences of the risky job which he has undertaken. Thus, “ a man cannot be said to be truly willing unless he is in a position to choose freely, and freedom of choice predicates, not only full knowledge of the circumstances in which the exercise of choice is conditional, so that he may b able to choose wisely, but the absence of any feeling of constraint so that nothing shall interfere with the freedom of his will. Thus, there is no volenti non fit injuria, when a servant is compelled to do some work despite his protests.

4. More knowledge does not imply assent

For the maxim Volenti non-fit injuria to apply, two points have to be proved:

The plaintiff knew that the risk was there
He, knowing the same, agreed to suffer the harm

If only the first of these points is present, i.e. there is only the knowledge of the risk, it is no defence because the maxim is volenti non fit injuria. Merely, because the plaintiff knows of the harm does not imply that he assents to suffer it.

In the case of Smith v. Baker

In this case, the plaintiff was a workman employed by the defendants to work a drill to cut a rock. With the help of a crane, stones were conveyed from one side to the other, and each time when the stones were conveyed, the crane passed over the plaintiff’s head. While he was busy with his work, a stone fell from the crane and injured him. The employers were negligent in not warning him at the moment of a recurring danger, although the plaintiff had been generally aware of the risk.

It was held in this case by the House of Lords that as there was mere knowledge of risk without the assumption of it, the maxim Volenti non-fit injuria did not apply, and the defendants were liable.

5. Negligence of the defendant

For the defence to be available, it is further necessary that the act done must be the same to which the consent has been given. Thus, if while playing hockey, I am injured while the game is being lawfully played, I can’t claim anything from any other player because I am deemed to have consented to the incidents of the game I have gone to play. In case, another player negligently or deliberately hits me with a stick, I can make him liable and he can’t plead volenti non-fit injuria because I never consented to an injury being caused in that manner. When the plaintiff consents to take some risk, the presumption is that the defendant will not be negligent.

Limitations on the scope of Volenti Non-Fit Injuria

Volenti non-fit injuria is a fundamental remedy under the law of torts that applies to situations where a person exposes himself to danger willingly. If a person willingly involves himself in acts that can lead to injury in this case he cannot claim for the remedy of Volenti non fit injuria. Here, are the limitations on the scope of volenti non-fit injuria:

1. Rescue Cases

Rsecsue cases from an exception to the applications of the doctrine of Volenti non-fit injuria. When the plaintiff voluntarily encounters a risk to rescue somebody from an imminent danger created by the defendant's wrongful act, he cannot be met with the defence of volenti non-fit injuria.

In the case of Hyanes v. Harwood

In this case, an important authority on the point. In that case, the defendant's servant left a two-horse van unattended in the street. A boy threw a stone at the horses and they bolted, causing grave danger to women and children on the road. A police station, on seeing the same, managed to stop the horses, but in doing so, he suffered serious personal injuries. It is a rescue case the defence of volenti non fit injuria was not accepted and the defendants were held liable.

When the defendant by his negligence has created a danger to the safety of A and he can foresee that somebody else, say B, is likely to rescue A from that danger, the defendant is liable to both A and B. Each one of them can bring an action independently of the other. The right of the rescuer is not affected by the defences which the defendant may be able to plead against the victim. The right of the rescuer is independent and is not derived from that of the victim. The victim may have been guilty of contributory negligence or his right may be excluded by contractual stipulation– but still, the rescuer can sue. So, also the victim may be a trespasser and excluded on that ground, but still the rescuer can sue.

The same principle will apply when somebody by his negligence puts himself in danger rather than any third person.

2. Illegal Acts

The doctrine of volenti non fit injuria is a remedy under the law torts, which acts as a defence for a person who knowingly involves himself in any risky act and cannot claim the remedy or defence of volenti non fit injuria.

Under the doctrine of volenti non fit injuria exception is when a person commits an illegal act. According to this exception, the harm suffered by a person is the result of any illegal act done by him in such a case the defendant is still liable for the damage sustained by the plaintiff whether or not the plaintiff voluntarily does it.

Illustration - A commits the act of trespassing onto B’s property and gets injured by the hazard present on B's property. In this circumstance, A after even having the knowledge or voluntarily assumed the risk by entering into B; 's property. In this case, B, the defendant will still be liable for any injuries sustained by A as it was B, the defendant failed to ensure the property’s safety from the hazard.

3. Due to the negligence of the defendant

Negligence of the defendant is one of the exceptions to the doctrine of Volenti non fit injuria. Under this exception, the harm suffered by the plaintiff is due to the defendant's negligence. When due to the defendant's negligence, the plaintiff sustains loss or suffers injury. In such a case the defendant has to pay damages to the plaintiff.

In the case of Slater v. Clay Cross Co. Ltd - In this case, the plaintiff was struck and injured by a train driver by the defendant’s servant while she was walking along a narrow tunnel on a railway track which was owned by the members of the public and had instructed its drivers to whistle and slow down when entering the tunnel. The accident occurred because the driver did not observe those instructions.

In this case, the defendant was held liable.

Difference between Volenti Non-Fit Injuria and contributory negligence

Volenti non fit injuria is a complete defence. Since the passing of the Law Reform (Contributory Negligence Act, 1945), the defendant's liability. Whereas in the case of contributory negligence, is based on the proportion of his fault in Matter. In such a case, therefore, the damages which the plaintiff can claim will be reduced to the extent that claims he was to blame for the loss.
In the defence of contributory negligence, both the plaintiff and the defendant are negligent. On the other hand, in volenti non fit injuria, the plaintiff may be volens but at the same time exercising due care for his safety. Moreover, the defendant’s negligence may rule out the application of the defence of volenti non fit injuria.
In the case of volenti non fit injuria, the plaintiff is always aware of the nature and extent of the danger which he encounters. Whereas, the contributory negligence on the part of the plaintiff in respect of a danger which he did not know although he ought to have known about it.

7. Can Volenti Non Fit Injuria be applied partially?

Volenti Non Fit Injuria is typically an all-or-nothing defense. Unlike comparative negligence, it doesn't allow for a partial reduction in damages. If successfully proven, it completely bars the plaintiff's claim. However, some jurisdictions may consider it as a factor in assessing contributory negligence.

8. How does the principle of Volenti Non Fit Injuria interact with the concept of duty of care?

Volenti Non Fit Injuria, if successfully invoked, can negate the duty of care owed by the defendant to the plaintiff. It essentially argues that the plaintiff's voluntary assumption of risk removes the defendant's legal obligation to protect the plaintiff from that specific risk.

9. What is the difference between Volenti Non Fit Injuria and waiver of liability?

While both involve the assumption of risk, Volenti Non Fit Injuria is a common law defense that arises from the plaintiff's conduct, while a waiver of liability is typically a contractual agreement. Waivers may be more easily enforced in some jurisdictions, but both can be limited by public policy considerations.

10. What is the relationship between Volenti Non Fit Injuria and assumption of risk?

Volenti Non Fit Injuria and assumption of risk are closely related concepts. In many jurisdictions, Volenti is considered a form of assumption of risk. Both involve the plaintiff knowingly and voluntarily accepting a risk, but Volenti is specifically a defense in tort law, while assumption of risk can have broader applications.

11. How does the element of knowledge affect the application of Volenti Non Fit Injuria?

Knowledge is crucial for Volenti Non Fit Injuria. The plaintiff must have full knowledge of the nature and extent of the risk they are assuming. If the defendant failed to disclose important information about the risk, or if the plaintiff misunderstood the risk, the defense may not apply.

13. Can Volenti Non Fit Injuria be applied retroactively?

Volenti Non Fit Injuria cannot be applied retroactively. The plaintiff must have knowledge and voluntarily accept the risk before the injury occurs. Accepting or acknowledging the risk after the fact does not constitute a valid defense under this principle.

14. How does Volenti Non Fit Injuria apply in cases of inherent risk?

Volenti Non Fit Injuria often applies in cases of inherent risk, where the danger is an integral part of the activity. For example, a boxer is considered to have accepted the inherent risks of the sport. However, this doesn't extend to risks that go beyond what's normally expected in the activity.

15. How does intoxication affect the application of Volenti Non Fit Injuria?

Intoxication can complicate the application of Volenti Non Fit Injuria. If the plaintiff was intoxicated to the point where they couldn't fully understand or voluntarily accept the risk, the defense may not apply. However, voluntarily becoming intoxicated and then engaging in risky behavior might still fall under Volenti in some circumstances.

16. How does Volenti Non Fit Injuria apply in cases involving professional risk-takers?

For professional risk-takers like stunt performers or professional athletes, Volenti Non Fit Injuria may apply more readily. Courts often consider that these individuals have a higher level of knowledge about the risks involved in their profession and have voluntarily chosen to accept these risks as part of their job.

17. Can Volenti Non Fit Injuria be applied in medical malpractice cases?

Volenti Non Fit Injuria is rarely applicable in medical malpractice cases. While patients may consent to treatment and its known risks, they do not consent to negligence or substandard care. The doctrine of informed consent in medical contexts is distinct from Volenti Non Fit Injuria.

18. Can Volenti Non Fit Injuria be used as a defense in cases of rescue attempts?

Volenti Non Fit Injuria is generally not applicable in rescue cases. The law encourages rescue attempts and doesn't consider rescuers to have voluntarily assumed the risk. This is known as the "rescue doctrine," which allows rescuers to claim compensation if they are injured while attempting to save others.

19. Can Volenti Non Fit Injuria be used as a defense in product liability cases?

Volenti Non Fit Injuria is generally not a strong defense in product liability cases. Manufacturers have a duty to produce safe products and warn of potential dangers. Even if a consumer uses a product knowing its risks, the manufacturer may still be liable if the product is defective or unreasonably dangerous.

20. Can Volenti Non Fit Injuria be used as a defense in cases of negligence per se?

Volenti Non Fit Injuria is generally not a valid defense against negligence per se, which arises from the violation of a statute designed to protect a specific class of persons. The rationale is that one cannot consent to a violation of law, especially when the law is intended for public safety.

21. Can Volenti Non Fit Injuria be applied in cases involving children?

Generally, Volenti Non Fit Injuria is not applicable to children, as they are often considered incapable of fully understanding and voluntarily assuming risks. Courts typically hold that children lack the capacity to give informed consent to assume risks, especially in dangerous situations.

22. How does public policy affect the application of Volenti Non Fit Injuria?

Public policy considerations can limit the application of Volenti Non Fit Injuria. Courts may be reluctant to apply this defense in situations where it would be against public interest, such as in cases involving essential public services or where it might encourage negligent behavior.

23. Is explicit consent always necessary for Volenti Non Fit Injuria to apply?

No, explicit consent is not always necessary. Volenti Non Fit Injuria can also apply in cases of implied consent, where the plaintiff's actions clearly demonstrate their willingness to accept the risk. However, the implied consent must be unambiguous and based on full knowledge of the potential dangers.

24. How does Volenti Non Fit Injuria apply in sports and recreational activities?

In sports and recreational activities, Volenti Non Fit Injuria often applies as participants are generally considered to have voluntarily assumed the inherent risks of the activity. However, this doesn't cover risks beyond what's normally expected in the sport or deliberate acts intended to cause harm.

25. Can an employer use Volenti Non Fit Injuria as a defense against workplace injury claims?

Employers generally cannot use Volenti Non Fit Injuria as a defense against workplace injury claims. Employment laws and regulations typically place the primary responsibility for workplace safety on the employer. Employees are not considered to have voluntarily assumed risks that arise from their employer's negligence.

26. What does "Volenti Non Fit Injuria" mean?

"Volenti Non Fit Injuria" is a Latin phrase meaning "to a willing person, injury is not done." In legal terms, it refers to a defense in tort law where the defendant claims that the plaintiff knowingly and voluntarily assumed the risk of harm, therefore absolving the defendant of liability.

27. How does the concept of informed consent in medical law relate to Volenti Non Fit Injuria?

While related, informed consent in medical law is distinct from Volenti Non Fit Injuria. Informed consent focuses on the patient's right to make decisions about their treatment after being fully informed of the risks and benefits. Volenti, on the other hand, is a broader legal defense against liability. In medical contexts, consenting to treatment doesn't mean consenting to negligence.

28. How does the principle of Volenti Non Fit Injuria apply in cases of spectator injuries at sporting events?

For spectator injuries at sporting events, Volenti Non Fit Injuria may apply to some extent. Spectators are generally considered to have assumed the normal risks associated with watching the sport, like being hit by a foul ball at a baseball game. However, this doesn't extend to all possible injuries, especially those resulting from the venue's negligence.

29. How does Volenti Non Fit Injuria interact with the concept of novus actus interveniens?

Volenti Non Fit Injuria and novus actus interveniens (a new intervening act) are separate defenses, but they can interact. If a plaintiff voluntarily assumes a risk, but then a new, unforeseeable event occurs that causes the injury, the defendant might argue both Volenti and novus actus interveniens to avoid liability.

30. Can Volenti Non Fit Injuria be used as a defense in cases involving inherently dangerous products?

For inherently dangerous products, Volenti Non Fit Injuria may apply if the danger was obvious and the plaintiff used the product knowing its risks. However, manufacturers still have a duty to make their products as safe as possible and to provide adequate warnings. The defense is less likely to succeed if the danger was hidden or if the product was more dangerous than a reasonable consumer would expect.

31. How does the concept of Volenti Non Fit Injuria interact with statutory duties?

Volenti Non Fit Injuria generally cannot override statutory duties. If a defendant has a statutory obligation to ensure safety, they usually cannot use Volenti as a defense, even if the plaintiff was aware of and accepted the risk. This is because statutory duties are often designed to protect individuals from themselves as well as others.

32. How does the principle of Volenti Non Fit Injuria apply in cases of emergency?

In emergency situations, the application of Volenti Non Fit Injuria may be limited. Courts often recognize that in emergencies, individuals may take risks they wouldn't normally accept. The voluntariness aspect of Volenti may be questioned if the plaintiff had no reasonable alternative but to face the risk.

33. How does Volenti Non Fit Injuria apply in cases involving multiple defendants?

When there are multiple defendants, Volenti Non Fit Injuria may apply differently to each. The plaintiff may be found to have voluntarily assumed the risk in relation to one defendant but not another, depending on the specific circumstances and the plaintiff's knowledge of each defendant's involvement.

34. Can a plaintiff's special knowledge or expertise affect the application of Volenti Non Fit Injuria?

Yes, a plaintiff's special knowledge or expertise can significantly affect the application of Volenti Non Fit Injuria. If the plaintiff has professional or specialized knowledge about the risks involved, courts may be more likely to find that they fully understood and voluntarily accepted those risks.

35. How does Volenti Non Fit Injuria apply in cases of obvious danger?

In cases of obvious danger, Volenti Non Fit Injuria may be more easily applied. If the risk is so apparent that any reasonable person would recognize it, courts may infer that the plaintiff voluntarily accepted this risk by proceeding. However, the obviousness of the danger alone is not always sufficient for the defense to succeed.

36. Can Volenti Non Fit Injuria be used as a defense in cases involving illegal activities?

Volenti Non Fit Injuria is generally not applicable in cases involving illegal activities. The law typically does not allow individuals to consent to illegal acts or their consequences. This is based on the principle that one cannot consent to a violation of the law or public policy.

37. Can Volenti Non Fit Injuria be applied in cases where the plaintiff was under duress?

Volenti Non Fit Injuria cannot be applied if the plaintiff was under duress. The principle requires that the assumption of risk be truly voluntary. If the plaintiff was coerced or had no reasonable alternative, their actions would not be considered voluntary, and the defense would fail.

38. How does Volenti Non Fit Injuria interact with the concept of vicarious liability?

Volenti Non Fit Injuria can potentially be used as a defense in cases of vicarious liability, but its application can be complex. If an employee voluntarily assumes a risk, it might protect both the employer and employee from liability. However, if the employer's negligence created the risk, Volenti may not apply.

39. Can Volenti Non Fit Injuria be used as a defense in cases of strict liability?

In cases of strict liability, Volenti Non Fit Injuria may still be applicable, but its use is often limited. Strict liability imposes responsibility regardless of fault, but if the plaintiff knowingly and voluntarily assumed the specific risk that led to their injury, the defense might succeed. However, this varies by jurisdiction and the nature of the strict liability offense.

40. How does the principle of Volenti Non Fit Injuria apply in cases of rescue by professionals?

Professional rescuers (like firefighters or police officers) are generally not subject to Volenti Non Fit Injuria for risks inherent to their job. This is known as the "firefighter's rule" in some jurisdictions. However, if they take unnecessary risks beyond their professional duties, Volenti might apply.

41. Can a minor's guardian consent on their behalf for the purposes of Volenti Non Fit Injuria?

Generally, a guardian cannot consent on behalf of a minor in a way that would invoke Volenti Non Fit Injuria. The law typically protects minors from the consequences of decisions they're not mature enough to make. However, there may be exceptions in some jurisdictions for certain activities, like organized sports.

42. How does Volenti Non Fit Injuria apply in cases where the risk was created by the defendant's negligence?

Volenti Non Fit Injuria typically does not apply when the risk was created by the defendant's negligence, even if the plaintiff was aware of this negligence. The defense is meant to cover inherent or obvious risks, not those created by the defendant's failure to meet their duty of care.

43. Can Volenti Non Fit Injuria be used as a defense in cases of attractive nuisance?

Volenti Non Fit Injuria is generally not applicable in cases of attractive nuisance, which typically involve children. The doctrine of attractive nuisance recognizes that children may not fully understand or appreciate risks, even if they're apparent. Therefore, property owners usually can't claim that a child voluntarily assumed the risk.

44. Can Volenti Non Fit Injuria be applied in cases where the plaintiff misunderstood the nature of the risk?

Volenti Non Fit Injuria cannot be applied if the plaintiff misunderstood the nature of the risk. The defense requires that the plaintiff had full knowledge of the risk they were accepting. If there was a misunderstanding about the type or extent of the risk, the defense would likely fail.

45. Can Volenti Non Fit Injuria be used as a defense in cases of failure to warn?

Volenti Non Fit Injuria is generally not a strong defense in failure to warn cases. If the defendant had a duty to warn about a risk and failed to do so, they usually can't claim that the plaintiff voluntarily assumed that risk. The defense is more applicable when the risk was obvious or the plaintiff had independent knowledge of it.

46. How does the principle of Volenti Non Fit Injuria apply in cases involving signed waivers or disclaimers?

Signed waivers or disclaimers can support a Volenti Non Fit Injuria defense, but they're not always conclusive. Courts will consider factors like the clarity of the waiver, whether it was properly explained, and whether it covers the specific risk that caused the injury. Public policy considerations may also limit the enforceability of waivers in some situations.

47. Can Volenti Non Fit Injuria be applied in cases where the plaintiff was unaware of the specific risk but knew the activity was generally dangerous?

The application of Volenti Non Fit Injuria in such cases can be complex. While the plaintiff may have known the activity was generally dangerous, they must have had knowledge of the specific risk that caused their injury for the defense to apply. Courts will consider the plaintiff's level of knowledge and whether the specific risk was a natural extension of the general dangers they were aware of.

48. How does Volenti Non Fit Injuria apply in cases of social host liability?

In social host liability cases, Volenti Non Fit Injuria might apply if the guest knowingly and voluntarily assumed risks associated with their behavior, such as choosing to drive after consuming alcohol. However, its application can be limited by public policy considerations and specific laws regarding host liability.
