Volenti Non Fit Injuria (Consent) (OCR A-Level Law): Revision Notes
Volenti Non Fit Injuria (Consent)
Introduction to volenti non fit injuria
Volenti non fit injuria (often shortened to volenti) is a complete defence to a claim in negligence. This Latin phrase translates as 'no injury is done to one who consents', and it operates to absolve the defendant entirely of liability for their actions.
There is significant overlap between volenti and contributory negligence. However, these defences produce different outcomes. While contributory negligence reduces damages according to the claimant's share of responsibility, volenti is an 'all or nothing' defence – if successful, the defendant escapes liability completely.
Since 1945, the courts have shown reluctance to apply volenti. Judges now prefer to apportion loss between the parties using contributory negligence rather than denying the claimant all compensation through volenti. This shift reflects a more balanced approach to justice in tort cases.
Definition and requirements
For the defence of volenti to succeed, the defendant must prove that there was a voluntary agreement by the claimant, in full knowledge of the circumstances.
This definition establishes three essential elements that must all be present:
- The agreement must be voluntary
- There must be agreement (express or implied)
- The claimant must have knowledge of the risk
Each element requires careful examination in any given case.
Elements of volenti non fit injuria
Voluntary agreement
The first requirement is that the claimant's agreement must be voluntary and freely entered. If the claimant was not in a position to exercise genuine free choice, the defence will fail.
This element becomes particularly important in three contexts:
- Employment relationships: where there may be economic pressure on employees
- Rescuers: who act in emergency situations
- Suicide cases: where the deceased's mental state is relevant
The courts scrutinize whether the claimant truly had the freedom to refuse or walk away from the risky situation. Mere acquiescence under pressure does not constitute voluntary agreement.
Agreement
The second element requires that the claimant actually agreed to accept the risk. This agreement may be express (clearly stated) or implied (inferred from conduct).
However, the claimant must demonstrate willingness to accept both the physical risks and the legal risks. This distinction is crucial. A person may understand that an activity is physically dangerous while still expecting others to take reasonable care. Accepting physical risk does not automatically mean accepting the legal right to claim compensation.
Lord Denning explained this principle in Nettleship v Weston (1971):
Knowledge of the risk of injury is not enough. Nothing will suffice short of an agreement to waive any claim for negligence. The [claimant] must agree expressly or impliedly to waive any claim for any injury that may befall him due to the lack of reasonable care by the defendant: or more accurately due to the failure by the defendant to measure up to the duty of care which the law requires of him.
This statement establishes that merely knowing about a danger is insufficient – there must be evidence that the claimant agreed to give up their legal right to sue for any resulting injury.
Worked Example: Smith v Charles Baker and Sons (1891)
Facts: Workers were loading stones into a steam crane that swung over an area where the claimant was working. A stone fell from the crane and struck him on the head, causing injury.
Key Issue: Did the claimant's awareness of the danger mean he consented to the employer's negligence?
Decision: The court held that although the claimant may have been aware of the danger inherent in the job, he had not consented to the employer's lack of care. In employment situations, knowing that a danger exists cannot be equated with agreeing to accept it. The employer still owed a duty to take reasonable care, which they had breached.
Principle: Awareness of workplace danger ≠ consent to negligence
Knowledge
The third element requires that the claimant must have full knowledge of the nature and extent of the risk involved. Partial or incomplete understanding is insufficient.
Worked Example: Morris v Murray (1991)
Facts: The claimant and defendant had been drinking heavily all day. The defendant, who was a pilot, suggested they take an aircraft for a flight. Shortly after takeoff, the aircraft crashed and the claimant suffered serious injuries.
Key Issue: Did the claimant have sufficient knowledge of the risk to establish volenti?
Decision: The Court of Appeal held that the risk of accepting a ride in an aircraft from an obviously heavily intoxicated pilot was so glaringly obvious and dangerous that the claimant could be taken to have voluntarily accepted it. The claimant had full knowledge of both the defendant's condition and the nature of flying, so he understood the magnitude of risk he was running.
Outcome: Volenti defence succeeded – the risk was obvious and the claimant had complete knowledge.
Special applications of volenti
Rescuers
The law treats rescuers differently when considering volenti. A person who intervenes to save others from danger is not regarded as having freely and voluntarily accepted the risk.
Worked Example: Haynes v Harwood (1935)
Facts: The defendant left a horse-drawn van unattended in a crowded street. When the horses bolted, a police officer was injured while trying to stop them to save a woman and children in their path.
Key Issue: Did the police officer voluntarily accept the risk by intervening?
Decision: The court ruled that the police officer did not 'freely' accept the risk. Rescuers typically act on instinct or duty in emergency situations, without the opportunity for calm reflection about the risks involved. The element of voluntary choice is absent in such circumstances.
Outcome: Volenti defence failed – rescuers are not considered to act voluntarily.
Policy Rationale for Rescuers
This principle recognizes that society benefits from encouraging rescue attempts, and it would be contrary to public policy to deny rescuers compensation through the volenti defence. The law does not want to discourage people from helping others in emergencies by removing their right to compensation if injured.
Sports participants
Participants in sporting events are generally taken to consent to the risk of injury which occurs during the ordinary performance of the sport. This reflects the reality that many sports involve inherent physical contact and risk.
However, this consent has clear limits, as shown in Condon v Basi (1985).
Worked Example: Condon v Basi (1985)
Facts: The claimant suffered a broken leg following a tackle during a football match.
Key Issue: Did participation in football mean the claimant consented to all injuries, including those from dangerous tackles?
Decision: The court held that while a participant accepts the risks inherent in sporting activities, they do not consent to injuries caused by conduct outside the rules of the game. If another player acts in breach of the rules or with reckless disregard for safety, volenti will not apply.
Principle: Consent to ordinary sporting risks ≠ consent to rule-breaking or reckless conduct
This balances the need to allow robust sporting competition with protecting participants from unreasonable violence or dangerous play.
Volenti and occupiers' liability
Special statutory provisions govern how volenti applies to occupiers' liability claims.
Section 2(5) of the Occupiers' Liability Act 1957 and section 1(6) of the Occupiers' Liability Act 1984 both provide that occupiers owe no duty in respect of risks willingly accepted by a person.
Key Difference in Statutory Volenti
Importantly, under these statutory provisions, there is no need to establish an agreement. The focus is simply on whether the visitor willingly accepted the risk. This makes the statutory version of volenti easier to establish than the common law defence.
Worked Example: Titchener v British Railways Board (1983)
Facts: The claimant was injured while trespassing on a railway line.
Key Issue: Did the claimant willingly accept the risk of crossing the railway line?
Decision: The court held that the claimant was fully aware of the obvious danger of crossing a train line. She must therefore be taken to have consented to assuming that risk. The railway operator owed her no duty in respect of such an obvious danger that she voluntarily encountered.
Outcome: Under the Occupiers' Liability Act 1984, the defence succeeded because the claimant willingly accepted an obvious risk.
Key cases summary
Essential Cases for Volenti Non Fit Injuria
Employment context
- Smith v Charles Baker and Sons (1891) – Knowing a workplace danger exists does not mean an employee consents to the employer's negligence. The employee retains the right to expect reasonable care.
Knowledge of risk
- Morris v Murray (1991) – Where a claimant accepts a lift from a heavily intoxicated pilot and the risk is glaringly obvious, volenti applies because the claimant had full knowledge of the extreme danger.
Rescuers
- Haynes v Harwood (1935) – Rescuers do not freely accept risk when acting to save others in emergency situations. The element of voluntary choice is missing.
Sports injuries
- Condon v Basi (1985) – Sports participants consent to ordinary risks of the game but not to injuries caused outside the rules or by reckless conduct.
Occupiers' liability
- Titchener v British Railways Board (1983) – Under the Occupiers' Liability Acts, a person who willingly encounters an obvious danger (such as crossing railway tracks) is taken to have accepted that risk.
Exam guidance
For problem questions:
When tackling a problem question involving volenti, follow this systematic approach:
- Identify whether volenti is a potential defence
- Apply each element systematically (voluntary, agreement, knowledge)
- Consider special contexts (employment, rescue, sports)
- Remember it's a complete defence – if successful, the defendant avoids all liability
- Consider whether contributory negligence might be more appropriate given judicial reluctance to apply volenti
For essay questions:
Strong essay answers should explore these key themes:
- Explain why courts have been reluctant to use volenti since 1945
- Compare and contrast volenti with contributory negligence – particularly the 'all or nothing' nature versus apportionment
- Discuss the policy reasons for treating rescuers differently
- Analyze the balance between protecting claimants and respecting autonomous choices
Key command words:
- Analyse: Break down the elements and explain how each operates
- Evaluate: Assess the strengths and weaknesses of the defence, particularly its 'all or nothing' nature
- Discuss: Explore the tension between volenti and contributory negligence
- Apply: Take each element in turn and apply it methodically to the facts
Remember!
Key Points to Remember:
- Volenti non fit injuria is a complete defence that absolves the defendant of all liability
- Three elements must be present: voluntary agreement, agreement (express or implied), and knowledge of the risk
- Since 1945, courts prefer using contributory negligence to apportion loss rather than the 'all or nothing' approach of volenti
- Knowing about a danger is not the same as agreeing to accept it – particularly important in employment cases (Smith v Charles Baker and Sons)
- Rescuers are not considered to have freely accepted risk (Haynes v Harwood)
- Sports participants consent to ordinary risks of the game but not injuries from conduct outside the rules (Condon v Basi)
- The Occupiers' Liability Acts 1957 and 1984 contain special provisions on volenti that do not require proof of agreement
