1. CORE STRUCTURE OF NEGLIGENCE

Main Exam Formula

• To prove negligence, the claimant must establish:

• Duty of care.

• Breach of duty.

• Factual causation.

• Legal causation.

• Remoteness of damage.

• Actual damage.

• If any one element fails, the negligence claim fails.

Basic Chain

• Did the defendant owe the claimant a duty of care?

• Did the defendant fall below the required standard of care?

• Did that breach cause the claimant’s damage?

• Was the damage legally connected to the breach?

• Was the damage reasonably foreseeable?

• Are there any defences or limitations?

2. NATURE OF LIABILITY IN NEGLIGENCE

Personal Liability

• Defendant is liable for their own negligent conduct.

• Apply when the defendant personally:

• Owed the duty.

• Breached the duty.

• Caused the damage.

• This is the ordinary form of negligence liability.

Vicarious Liability

• One person may be liable for another person’s tort.

• Usually applies to employer and employee.

• Apply only in outline unless the question focuses on it.

• Check:

• Was there an employment relationship?

• Did the employee commit a tort?

• Was the tort committed in the course of employment?

Joint Liability

• More than one defendant may be responsible for the same damage.

• Claimant may recover full compensation from one defendant.

• That defendant may later seek contribution from others.

3. DUTY OF CARE

Meaning

• Duty of care means a legal obligation to take reasonable care to avoid causing harm.

• It is the first stage of negligence.

• If no duty exists, the claim fails immediately.

Established Duty Situations

• Some relationships automatically suggest a duty, such as:

• Doctor and patient.

• Driver and road user.

• Employer and employee.

• Teacher and student.

• Manufacturer and consumer.

• In these cases, do not waste time over-explaining Caparo unless the question requires it.

Novel Duty Situations

• If the duty is not already established, apply the modern duty test.

Neighbour Principle

• A person must take reasonable care to avoid acts or omissions likely to injure people closely and directly affected by their conduct.

• Use this as the foundation of duty of care.

• It supports the idea that foreseeable victims should be protected.

Caparo Three-Part Test

1. Reasonable Foreseeability

• Was it reasonably foreseeable that the defendant’s conduct could harm the claimant?

• If the harm was unpredictable, no duty is likely.

2. Proximity

• Was there a sufficiently close relationship between claimant and defendant?

• Proximity may be:

• Physical closeness.

• Relationship-based closeness.

• Circumstantial closeness.

3. Fair, Just and Reasonable

• Would it be fair, just and reasonable to impose liability?

• This is where policy arguments enter.

• Courts may deny duty even if harm is foreseeable.

Policy Considerations In Duty

• Courts consider:

• Floodgates risk.

• Defensive practices.

• Burden on public services.

• Economic consequences.

• Indeterminate liability.

• Public interest.

• Fairness to claimant and defendant.

• Policy is especially important in:

• Police liability.

• Public authorities.

• Pure economic loss.

• Nervous shock.

• Novel duty situations.

4. BREACH OF DUTY

Meaning

• Breach occurs when the defendant falls below the standard of care required by law.

• The court asks:

• Did the defendant act as a reasonable person would have acted in the circumstances?

Objective Standard

• The standard is objective.

• Defendant’s personal weakness, inexperience or poor judgment is usually irrelevant.

• The reasonable person is:

• Careful.

• Ordinary.

• Sensible.

• Not perfect.

• Not unusually cautious.

Different Classes Of Defendant

Ordinary Adults

• Judged by the reasonable person standard.

Learner Drivers

• Judged by the standard of a reasonably competent qualified driver.

• Inexperience is no defence.

Children

• Judged by the standard of a reasonable child of the same age.

• Do not apply adult standards to children.

Professionals

• Judged by the standard of a reasonably competent professional in that field.

• A professional is usually not negligent if supported by a responsible body of professional opinion.

• However, the professional opinion must be logical and defensible.

Experts

• Judged by the standard of a reasonably competent expert in that area.

• Greater skill means a higher standard.

5. FACTORS USED TO DECIDE BREACH

1. Foreseeability Of Harm

• If harm was not reasonably foreseeable, breach is unlikely.

• The more obvious the risk, the greater the duty to take precautions.

2. Magnitude Of Risk

• The more serious the possible harm, the more precautions are required.

• Even a small chance of serious injury may require action.

3. Cost And Practicality Of Precautions

• Courts ask whether precautions were reasonable and practical.

• The law does not require defendants to remove every possible risk.

• It requires reasonable care, not perfection.

4. Social Utility

• If the defendant’s activity has public benefit, courts may tolerate greater risk.

• Emergency services may be judged with this in mind.

5. Special Characteristics Of Claimant

• If defendant knows claimant is especially vulnerable, more care may be required.

• Example:

• One-eyed worker.

• Child claimant.

• Disabled claimant.

6. RES IPSA LOQUITUR

Meaning

• “The thing speaks for itself.”

• Used where the accident strongly suggests negligence but claimant cannot prove exactly what happened.

Requirements

• The type of accident would not normally happen without negligence.

• The thing causing damage was under defendant’s control.

• There is no other obvious explanation.

Exam Use

• Use only where the facts say the cause is unclear.

• Do not overuse it in ordinary breach questions.

7. FACTUAL CAUSATION

Meaning

• Factual causation asks whether the defendant’s breach actually caused the damage.

“But For” Test

• Ask:

• But for the defendant’s breach, would the claimant have suffered the damage?

Result

• If damage would not have happened without the breach:

• Factual causation is satisfied.

• If damage would have happened anyway:

• Factual causation fails.

8. MULTIPLE CAUSES

Problem

• Sometimes more than one factor causes the damage.

• The normal “but for” test may be too strict.

Material Contribution

• Defendant may be liable if their breach materially contributed to the injury.

• Contribution must be more than minimal.

• Defendant does not need to be the only cause.

Material Increase In Risk

• Used where science cannot prove exactly which exposure caused disease.

• If defendant materially increased risk of injury, causation may be satisfied.

• Mainly used in difficult industrial disease cases.

Successive Causes

• Where one injury is followed by another event, ask:

• Did the second event replace the first cause?

• Or does the first defendant remain responsible?

• Natural illness may reduce damages.

• Later tortious injury may not automatically remove original liability.

9. LEGAL CAUSATION

Meaning

• Legal causation asks whether the defendant should be legally responsible for the damage.

• The breach must remain an operating and significant cause.

Key Chain

• Was defendant’s breach still a significant cause?

• Did anything break the chain of causation?

• Was the later event independent and unforeseeable?

10. INTERVENING ACTS

Meaning

• A novus actus interveniens is a new intervening act that breaks the chain of causation.

Acts Of Third Parties

• A third party’s independent and unreasonable act may break the chain.

• But ordinary foreseeable mistakes may not.

Acts Of Claimant

• Claimant’s own unreasonable conduct may break the chain.

• Reasonable rescue attempts usually do not break the chain.

Medical Treatment

• Ordinary negligent medical treatment usually does not break the chain.

• Grossly abnormal medical treatment may break the chain, but this is rare.

11. REMOTENESS OF DAMAGE

Meaning

• Remoteness limits liability to damage that is not too distant.

• Even if causation is proved, the claimant must show the damage was legally recoverable.

Main Test

• The type of damage must be reasonably foreseeable.

What Must Be Foreseeable?

• The general kind/type of damage must be foreseeable.

• The exact way it happened does not need to be foreseeable.

• The full extent of injury does not need to be foreseeable.

Thin Skull Rule

• Defendant must take the claimant as found.

• If some injury was foreseeable, defendant is liable for the full extent of injury, even if claimant’s condition made it much worse.

12. COMPLETE PROBLEM QUESTION METHOD

Step 1: Identify Claimant And Defendant

• Who is suing whom?

• What damage was suffered?

Step 2: Duty Of Care

• Is this an established duty situation?

• If not, apply:

• Foreseeability.

• Proximity.

• Fair, just and reasonable.

Step 3: Breach

• Identify the correct standard of care.

• Apply breach factors:

• Risk.

• Seriousness.

• Cost of precautions.

• Social utility.

• Defendant’s class.

Step 4: Factual Causation

• Apply the “but for” test.

• If multiple causes exist, consider material contribution or material increase in risk.

Step 5: Legal Causation

• Ask whether defendant’s breach remained a significant cause.

• Consider whether an intervening act broke the chain.

Step 6: Remoteness

• Was the type of damage reasonably foreseeable?

• Apply thin skull rule if claimant had unusual vulnerability.

Step 7: Defences

• Consider:

• Consent.

• Volenti.

• Contributory negligence.

• Necessity.

• Self-defence where relevant.

Step 8: Conclusion

• State clearly:

• Claim likely succeeds.

• Claim likely fails.

• Liability may be reduced.

• Multiple defendants may share responsibility.

13. ESSAY EVALUATION POINTS

Strengths Of Negligence

• Flexible and adaptable.

• Protects victims.

• Encourages careful behaviour.

• Balances claimant and defendant interests.

• Allows courts to control liability through duty, breach, causation and remoteness.

Weaknesses Of Negligence

• Duty tests can be uncertain.

• Policy considerations create unpredictability.

• Causation rules are complex.

• Multiple cause cases can produce unfairness.

• Claimants may fail despite real harm.

• Public authority cases may favour defendants too strongly.

14. FINAL EXAM CHAINS TO MEMORISE

Duty Chain

• Foreseeability → proximity → fair, just and reasonable → policy.

Breach Chain

• Foreseeable type of damage → exact method irrelevant → thin skull rule.

Liability Chain

• Duty → breach → causation → remoteness → damage → defences → remedy.
