Liability in Negligence (OCR A-Level Law): Revision Notes
Liability for Injury to People and Damage to Property
Introduction to liability for injury and property damage
Negligence law allows claimants to seek compensation when they suffer harm due to another person's failure to take reasonable care. This harm can take two main forms: personal injury (including death) and damage to property. Understanding when the law recognises these types of damage as actionable is fundamental to establishing liability in negligence.
For a negligence claim to succeed, the claimant must prove three essential elements:
- The defendant owed them a duty of care
- The defendant breached that duty
- The breach caused actionable damage
This note focuses on the types of damage that the law recognises and the establishment of a duty of care.
What constitutes actionable personal injury?
Legal definition of personal injury
The Supreme Court case of Dryden v Johnson Matthey plc (2018) provided, for the first time, a clear legal definition of what constitutes actionable personal injury. This landmark decision established specific criteria that must be satisfied before a person can bring a claim for personal injury in negligence.
Case Context: Dryden v Johnson Matthey plc (2018)
The claimant in Dryden worked in a factory manufacturing catalytic converters, where exposure to platinum salts caused illness. The Supreme Court used this case to clarify when physical harm becomes legally actionable, establishing the first comprehensive legal definition of actionable personal injury.
Requirements for actionable personal injury
Three Requirements for Actionable Personal Injury
For an injury to be actionable in negligence, all three of these requirements must be met:
-
There must be an impairment of a person's physical condition - This means the claimant must have suffered some form of physical deterioration or dysfunction. The impairment could affect bodily systems, organs, or overall physical health.
-
The impairment must be more than trivial - Not every minor inconvenience or discomfort qualifies as actionable injury. The harm must reach a threshold of seriousness that makes legal intervention appropriate. Completely insignificant or fleeting discomforts fall below this threshold.
-
The person must be worse off, physically or economically - The injury must result in some form of detriment, whether that manifests as reduced physical capability or economic loss. Crucially, compensation must be an appropriate remedy for the harm suffered.
Scope of personal injury
Personal injury includes harm to a person's physical capacity for enjoying life. Importantly, the absence of visible symptoms does not prevent a condition from amounting to actionable personal injury. For example, internal damage, progressive conditions, or asymptomatic injuries that nonetheless impair function can all constitute actionable harm.
The definition encompasses death, which represents the most severe form of personal injury. In such cases, dependants or the deceased's estate may bring claims for the loss suffered.
Damage to property
Damage to property refers specifically to harm caused to personal property belonging to the claimant. This category covers tangible items that a person owns, such as houses, cars, mobile phones, clothing, and other possessions.
When analysing problem scenarios, look for damage to physical items belonging to the claimant. For example, if a car accident occurs due to someone's negligent driving, the negligent driver will be liable not only for personal injuries sustained by other road users but also for damage caused to their vehicles. Similarly, if negligent building work causes damage to a homeowner's house, this would constitute actionable property damage.
Distinction from Personal Injury
The law treats property damage as a distinct category from personal injury, though both can arise from the same negligent act. Claimants can recover compensation for:
- The cost of repairing damaged property
- The cost of replacing damaged property
- The reduction in value if the property cannot be fully restored
The elements required for an action in negligence
To succeed in a negligence claim, the claimant must establish three core elements: duty of care, breach of duty, and causation of actionable damage. The first of these elements, duty of care, determines whether the defendant had a legal obligation to take care not to harm the claimant.
Establishing a duty of care
When does a duty of care exist?
Some duties of care are well-established in law and do not require fresh analysis in each case. These established duties exist between certain categories of people based on their relationships. Examples include:
- Road users owe duties to other road users (drivers, cyclists, pedestrians)
- Teachers owe duties to their pupils
- Doctors and medical professionals owe duties to their patients
- Employers owe duties to their employees
When a case involves these established relationships, the court can proceed directly to examining whether the duty was breached, without needing to determine whether a duty exists in the first place.
Novel Situations Require Legal Tests
When faced with a novel situation where no established duty exists, the courts must decide whether to recognise a new duty of care. This is where the legal tests become crucial. You cannot simply assume a duty exists—you must apply the appropriate legal framework.
The neighbour principle: Donoghue v Stevenson (1932)
The foundational test for duty of care was established in the landmark case of Donoghue v Stevenson (1932). In this famous case, the claimant discovered a decomposed snail in her bottle of ginger beer, which caused her to suffer shock and gastroenteritis. Because she had not purchased the drink herself, she had no contract with the manufacturer or retailer.
The Neighbour Principle Established
The House of Lords, led by Lord Atkin, established the "neighbour principle", which asks: who is my neighbour in law?
The answer provided a general principle for determining when a duty of care exists:
- You must take reasonable care to avoid acts or omissions which you can reasonably foresee are likely to injure your neighbour
- Your neighbour is anyone so closely and directly affected by your actions that you ought reasonably to have them in your contemplation when directing your mind to the acts or omissions in question
Key Achievement: This principle established that manufacturers owe duties to ultimate consumers, even without a contractual relationship. More broadly, it created a general framework for recognising duties of care based on foreseeability and proximity.
The modern test: Caparo v Dickman (1990)
The case of Caparo v Dickman (1990) updated and refined the neighbour principle, establishing the modern three-part test for duty of care. The case involved shareholders who claimed that auditors had negligently overvalued a company's shares, causing them financial loss.
The Caparo Three-Part Test
The House of Lords established that a duty of care would only be imposed where three conditions are satisfied:
- The damage must be reasonably foreseeable
- There must be a relationship of proximity between the parties
- It must be fair, just and reasonable to impose a duty of care
This test refined the language of the neighbour principle and added the important third element, which allows courts to consider policy factors when deciding whether to impose a duty.
Application of the Caparo test: Robinson v Chief Constable of West Yorkshire (2018)
The Supreme Court case of Robinson v Chief Constable of West Yorkshire (2018) provided important clarification about when the Caparo test should be used. The claimant, an elderly woman, was injured when police officers attempted to arrest a drug dealer who resisted, knocking her to the ground.
When to Apply the Caparo Test
The Supreme Court held that the Caparo test should only be used in novel cases where established legal principles do not already provide an answer. If previous cases exist that are sufficiently similar to the situation at hand, courts should apply those established principles rather than conducting a fresh Caparo analysis.
Additional Clarification: The Robinson case also confirmed that there is no blanket immunity for police forces. While policy considerations may prevent duties arising in some contexts (such as the investigation and detection of crime), police officers can owe duties of care to members of the public in appropriate circumstances, particularly where their actions create foreseeable risks.
Understanding the three elements of the Caparo test
Element 1: Reasonable foreseeability
The first element requires that the type of damage suffered must have been reasonably foreseeable at the time of the defendant's actions. This is assessed objectively, meaning the court asks what a reasonable person in the defendant's position would have foreseen, not what this particular defendant actually foresaw.
Foreseeability is a broad concept. The defendant need not foresee the exact chain of events or the precise manner in which harm occurs, but they must be able to foresee that harm of the general type that occurred might result from their actions.
Illustrating Foreseeability: Kent v Griffiths (2000)
An ambulance service was called to attend to a patient suffering an asthma attack but arrived unreasonably late without explanation.
Outcome: The court held that it was reasonably foreseeable that delay in providing emergency medical assistance could worsen the patient's condition and cause harm. The damage was therefore foreseeable.
Key Point: The ambulance service should have anticipated that failing to arrive promptly could result in harm to someone in a medical emergency.
Broad Interpretation of Foreseeability: Jolley v Sutton LBC (2000)
A council left an abandoned boat in a public park for over two years. A child was injured when attempting to repair the boat and it fell on him.
Council's Argument: The specific manner of injury was not foreseeable (they couldn't predict a child would try to repair the boat).
Court's Decision: The House of Lords held that it was reasonably foreseeable that a child would be injured by a boat left abandoned in a park where children played. The general risk of children being harmed by the dangerous object was sufficient—the court did not require foreseeability of the exact mechanism of injury.
Principle: Foreseeability focuses on the general type of harm, not the specific circumstances of how it occurs.
Element 2: Proximity
Proximity refers to the closeness of the relationship between the parties. This closeness can be assessed in several ways:
- Time: How close in time was the defendant's action to the claimant's harm?
- Space: How close physically were the parties?
- Relationship: What was the nature of the relationship between the parties?
Proximity is not merely about physical or temporal closeness but also encompasses whether there is a sufficient legal connection between the parties to justify imposing a duty.
Absence of Proximity: Bourhill v Young (1943)
Known as the "nosy fishwife" case, a pregnant woman heard a motorcycle accident and chose to approach the scene, where she witnessed the aftermath. She subsequently suffered nervous shock and claimed against the motorcyclist's estate.
Outcome: The House of Lords held there was insufficient proximity because she was not within the range of foreseeable impact and had chosen to view the scene when she could have avoided it.
Key Factor: Her voluntary decision to expose herself to the distressing scene negated proximity.
Presence of Proximity: McLoughlin v O'Brian (1983)
The claimant rushed to the hospital after being told her family had been in a serious road accident. She saw her injured family members in distressing circumstances and suffered psychiatric injury as a consequence.
Outcome: The House of Lords held that there was proximity in this case because:
- She had witnessed the immediate aftermath of the accident
- She had no real choice about whether to attend the hospital
- Her relationship to the primary victims created a close connection
- The closeness in time and space was significant
Contrast with Bourhill: Unlike Bourhill, McLoughlin did not voluntarily expose herself to the scene—she had to attend to her injured family members.
Element 3: Fair, just and reasonable
The third element of the Caparo test introduces policy considerations into the assessment of duty. Even where harm is foreseeable and there is proximity, the court may still refuse to impose a duty if it would not be fair, just and reasonable to do so.
This element allows courts to consider broader implications of recognising a duty of care, including:
- Whether imposing a duty would place an unreasonable burden on the defendant's operations or budget
- Whether recognising the duty might open the floodgates to numerous similar claims
- Whether imposing the duty would be contrary to public interest
- Whether other areas of law already provide adequate remedies
Particular Significance for Public Authorities
This element is particularly significant when claims are brought against public authorities, especially the police, emergency services, and local authorities. Courts must balance protecting individuals against allowing public bodies to function effectively without fear of constant litigation.
Policy Restrictions on Police Liability: Hill v Chief Constable of West Yorkshire (1988)
The mother of one of the Yorkshire Ripper's victims sued the police for failing to catch the serial killer before he murdered her daughter.
Decision: The House of Lords held that it was not fair, just and reasonable for the police to owe a duty of care to individual members of the public in relation to the detection and investigation of crime.
Reasoning included:
- Imposing such a duty would encourage defensive policing practices
- Police resources might be diverted from investigating crimes to avoiding litigation
- Determining the standard of care would be extremely difficult
- The risk of numerous claims would burden police operations
Follow-up: This principle was followed in Michael v Chief Constable of South Wales (2015), where the Supreme Court upheld that police generally do not owe duties in relation to crime investigation and prevention.
But Remember: The Robinson case clarified that there is no blanket immunity. Police can owe duties in other contexts, particularly where they create risks through their operational activities.

Exam approach
Systematic Approach to Duty of Care Problem Questions
-
Identify the relationship between parties - check if an established duty exists
- Look for road users, teacher-pupil, doctor-patient, employer-employee relationships
- If an established duty exists, state this and move to breach analysis
-
If no established duty, apply Caparo systematically:
- State the three-part test clearly
- Apply each element to the facts in turn
- Use case law to support your analysis at each stage
-
Use case facts to illustrate legal principles
- Example: "similar to Jolley v Sutton LBC where it was foreseeable that a child would be injured by a boat in a park..."
- This demonstrates understanding and application skills
-
Consider policy factors especially in cases involving public authorities
- Apply the "fair, just and reasonable" element carefully
- Reference Hill v Chief Constable for police cases
-
Reach a clear conclusion on whether a duty exists
- Be definitive where the law is clear
- Acknowledge uncertainty where appropriate
When evaluating the law on duty of care:
- Consider whether the Caparo test provides sufficient certainty or is too flexible
- Examine whether the "fair, just and reasonable" element gives judges too much discretion
- Evaluate whether policy considerations should restrict duties owed by public authorities
- Consider whether the law adequately balances protecting claimants with avoiding defensive practices by professionals
Common Pitfalls to Avoid
- Don't apply Caparo when an established duty already exists (waste of time and shows lack of understanding of Robinson)
- Don't treat foreseeability as requiring prediction of exact circumstances—focus on general type of harm
- Don't forget to consider all three Caparo elements—students often neglect "fair, just and reasonable"
- Don't assume proximity exists simply because harm was foreseeable—these are separate elements
Key Points to Remember
-
Actionable personal injury requires: physical impairment, more than trivial damage, and compensation must be appropriate (Dryden v Johnson Matthey plc 2018)
-
Property damage covers personal possessions like vehicles, houses, phones, and other tangible items
-
Established duties exist between road users, teachers-pupils, doctors-patients, and employers-employees without needing to apply tests
-
Caparo three-part test: damage must be reasonably foreseeable, there must be proximity, and it must be fair, just and reasonable to impose a duty
-
Caparo only applies to novel cases where no established precedent exists (Robinson v Chief Constable 2018)
-
Foreseeability is assessed objectively and covers general types of harm, not specific mechanisms (Jolley v Sutton LBC)
-
Proximity involves closeness in time, space and relationship; choosing to expose yourself to harm negates proximity (Bourhill v Young vs McLoughlin v O'Brian)
-
Fair, just and reasonable element allows policy considerations, particularly restricting duties on public authorities in certain contexts (Hill v Chief Constable)
