Chapter 1: Foundations – What Is Negligence

Introduction: Tort Law and the Role of Negligence

Tort law governs civil wrongs that cause loss or harm. A tort is an act or omission that gives rise to injury or harm to another and amounts to a civil wrong for which courts impose liability. Negligence is the most common tort. It arises when a person breaches a duty of care owed to another, causing damage.

Unlike intentional torts such as battery or trespass, negligence does not require intent to harm. The law imposes an objective standard: what would a reasonable person have done in the same circumstances. Negligence law balances freedom of action against the need to compensate those injured by carelessness.

The primary purposes of negligence law are compensation, deterrence, and loss distribution. By holding parties liable, the law encourages reasonable conduct and spreads losses through insurance and enterprise liability.

Historical Development: From No Duty to the Neighbour Principle

Historically, courts were reluctant to impose liability for pure omissions or for harm to strangers. Early product liability required privity of contract. The modern law of negligence developed through case law.

Case Law: Donoghue v Stevenson AC 562
View Case: Donoghue v Stevenson
Mrs. Donoghue became ill after drinking ginger beer containing a decomposed snail. She had not purchased the drink and had no contract with the manufacturer. The House of Lords held that a manufacturer owes a duty of care to the ultimate consumer. Lord Atkin formulated the “neighbour principle”: you must take reasonable care to avoid acts or omissions which you can reasonably foresee would be likely to injure your neighbour. Neighbours are persons so closely and directly affected by your act that you ought reasonably to have them in contemplation. This case established the modern foundation for the duty of care.

Negligence vs. Other Torts and Crimes

• Negligence vs. Intentional Torts: Battery requires intentional harmful or offensive contact. Negligence requires only failure to use reasonable care.
• Negligence vs. Strict Liability: Strict liability imposes responsibility without fault, common in product liability and ultrahazardous activities. Negligence requires proof of fault.
• Negligence vs. Breach of Contract: Contract claims arise from promises. Negligence arises from duties imposed by law regardless of agreement. The same conduct can give rise to both claims.
• Civil vs. Criminal: Negligence is generally civil. Criminal negligence requires gross deviation from reasonable care and is prosecuted by the state.

Chapter 2: The Four Elements – Duty, Breach, Causation, Damages

Element 1: Duty of Care

A duty of care exists when the law recognizes a relationship between defendant and claimant requiring the defendant to act with reasonable care. Not every careless act creates liability. The court asks whether it is just, fair, and reasonable to impose a duty.

Tests for duty:

• Foreseeability: Was harm to the claimant reasonably foreseeable. In Donoghue, injury to a consumer was foreseeable to a manufacturer.
• Proximity: Was there a sufficiently close relationship between parties. This includes physical, circumstantial, or causal proximity.
• Fair, just, and reasonable: Policy factors may negate a duty even if foreseeability and proximity exist. Courts consider floodgates, insurance, and the role of public authorities.

Established duty categories: Doctors to patients, drivers to other road users, employers to employees, occupiers to visitors, manufacturers to consumers, and schools to pupils.

Element 2: Breach of Duty

Breach occurs when the defendant’s conduct falls below the standard of care required. The standard is that of the reasonable person: an objective standard representing the ordinary prudent person.

Factors courts consider:

• Likelihood of harm: Greater risk requires greater precaution. In Bolton v Stone, the low probability of a cricket ball hitting a passerby meant no breach.
• Severity of harm: Risk of serious injury demands more care. In Paris v Stepney Borough Council, a one-eyed mechanic was owed a higher duty regarding eye protection.
• Cost of precautions: Courts balance risk against burden. In Latimer v AEC Ltd, closing a factory due to a slippery floor was too high a burden when the risk was addressed by warnings and sawdust.
• Social utility: Socially useful conduct may justify greater risk. Emergency services may drive faster.

Professional standard: Professionals are judged against the standard of a reasonably competent professional in that field. In Bolam v Friern Hospital Management Committee, a doctor is not negligent if he acted in accordance with a practice accepted as proper by a responsible body of medical opinion.

Case Law: Nettleship v Weston 1 QB 691
View Case: Nettleship v Weston
A learner driver was held to the standard of a competent driver. The Court of Appeal held that the standard of care is objective and does not vary with inexperience. All drivers owe the same duty to other road users.

Element 3: Causation – Factual and Legal

The claimant must prove the breach caused the damage. Causation has two parts.

Factual causation: The “but for” test. But for the defendant’s breach, would the damage have occurred. In Barnett v Chelsea & Kensington Hospital, a doctor’s failure to examine a patient was a breach, but the patient would have died anyway from arsenic poisoning. Factual causation failed.

Legal causation: Also called remoteness. The damage must not be too remote. In The Wagon Mound No 1, oil spilled by defendants ignited when molten metal fell on it. The Privy Council held damage by fire was not reasonably foreseeable, so defendants were not liable for that loss. The test is reasonable foreseeability of the type of damage.

Intervening acts: A novus actus interveniens may break the chain of causation if it is not foreseeable. In Knightley v Johns, a police officer’s negligent directions after a road accident broke the chain between the original driver’s negligence and a subsequent collision.

Element 4: Damages

Damage is the gist of negligence. Without actual loss, there is no claim. Damage includes personal injury, property damage, economic loss, and psychiatric injury.

Types of damages:

• Compensatory: Aim to restore the claimant to the position they would have been in had the tort not occurred. Includes special damages for quantifiable losses and general damages for pain and suffering.
• Nominal: Recognize a rights violation where no substantial loss occurred. Rare in negligence.
• Punitive: Punish and deter. Generally not available in negligence unless conduct was reckless or wanton.

The claimant must mitigate loss. Failure to take reasonable steps to reduce damage may reduce recovery.

Chapter 3: Special Duties and Standards of Care

Occupiers’ Liability

Occupiers of premises owe duties to visitors under statute. In England and Wales, the Occupiers’ Liability Act 1957 requires occupiers to take reasonable care that visitors are reasonably safe in using the premises for the purposes for which they are invited or permitted. For trespassers, the Occupiers’ Liability Act 1984 imposes a lower duty: to avoid injury from dangers the occupier knows or has reasonable grounds to know exist.

Case Law: Tomlinson v Congleton Borough Council UKHL 47
View Case: Tomlinson v Congleton BC
A man dived into a shallow lake and was injured. The House of Lords held the council owed no duty to protect against obvious risks freely undertaken. The case confirmed that occupiers are not insurers and that social value of activities matters.

Employers’ Liability

Employers owe employees a duty to provide a safe place of work, safe plant and equipment, competent staff, and a safe system of work. This is a personal, non-delegable duty.

Vicarious liability: Employers are liable for torts of employees committed in the course of employment. In Lister v Hesley Hall Ltd, the House of Lords held an employer vicariously liable for sexual abuse by a warden because the abuse was closely connected to employment.

Case Law: Wilsons & Clyde Coal Co v English AC 57
View Case: Wilsons & Clyde Coal Co v English
The House of Lords confirmed the employer’s duty to provide a safe system of work is non-delegable. An employer cannot escape liability by delegating safety to a manager.

Professional Negligence

Professionals owe a duty to clients and, in limited cases, third parties. The standard is that of a reasonably competent professional. In medical cases, the Bolam test applies, modified by Bolitho v City and Hackney HA, which requires that the body of opinion have a logical basis.

Solicitors, accountants, architects, and financial advisors may be liable for economic loss caused by negligent advice. In Hedley Byrne v Heller, the House of Lords held that a bank could owe a duty of care for negligent misstatement causing pure economic loss where there was a special relationship and reliance.

Case Law: Hedley Byrne & Co Ltd v Heller & Partners Ltd AC 465
View Case: Hedley Byrne v Heller
The claimants relied on a bank reference given by the defendants. Although the reference was inaccurate, the bank avoided liability due to a disclaimer. The case established liability for negligent misstatement causing economic loss where a special relationship exists.

Chapter 4: Defenses and Comparative Fault

Contributory Negligence and Comparative Fault

If the claimant’s own negligence contributed to the damage, damages are reduced. Under the Law Reform (Contributory Negligence) Act 1945, damages are reduced to such extent as the court thinks just and equitable having regard to the claimant’s share in responsibility.

In Sayers v Harlow UDC, a woman injured while climbing out of a locked toilet was 25% contributorily negligent for attempting a dangerous exit. In Froom v Butcher, damages were reduced by 20% for failure to wear a seatbelt.

Many U.S. states apply comparative fault. Pure comparative fault allows recovery reduced by plaintiff’s percentage of fault. Modified comparative fault bars recovery if the plaintiff is 50% or 51% or more at fault.

Volenti Non Fit Injuria and Exclusion Clauses

Volenti non fit injuria: To a willing person, no injury is done. The defense applies where the claimant freely and voluntarily accepted the risk with full knowledge. In Smith v Baker, a worker injured by a crane was not volens because he had protested the unsafe system.

Exclusion clauses: Attempts to limit or exclude liability. Under the Unfair Contract Terms Act 1977, liability for death or personal injury caused by negligence cannot be excluded. Other losses can be excluded only if reasonable.

Rescuers are rarely held volens. In Haynes v Harwood, a policeman injured stopping runaway horses was not volens because he acted under duty.

Illegality and Limitation

Ex turpi causa: No action arises from a base cause. If the claimant was engaged in illegal conduct, the claim may fail. In Gray v Thames Trains, a claimant who killed in a train crash caused by negligence could not recover damages for detention after the killing.

Limitation: Claims must be brought within time limits. For personal injury, the Limitation Act 1980 sets a three-year period from the date of knowledge. For property damage, six years. Courts have discretion to extend time in personal injury cases.

Chapter 5: Dispute Resolution and Risk Management

Litigation Process in Negligence Claims

Negligence claims begin with a letter of claim under the Pre-Action Protocol for Personal Injury Claims. The defendant must respond within 21 days and investigate within three months. Most claims settle before trial. If not, the claimant issues proceedings.

The claimant bears the burden of proving duty, breach, causation, and damage on the balance of probabilities. Expert evidence is often required for breach and causation in professional negligence and medical cases.

Courts encourage alternative dispute resolution. Mediation and arbitration can resolve claims faster and preserve relationships.

Organizational Risk Management

Organizations reduce negligence exposure through:

• Risk assessment: Identify foreseeable risks to employees, customers, and the public. The Management of Health and Safety at Work Regulations 1999 require risk assessments.
• Policies and training: Implement health and safety policies, train staff, and keep records. OSHA requires employers to provide a workplace free from recognized hazards under the General Duty Clause.
• Insurance: Employers’ liability insurance is compulsory in the UK. Public liability and professional indemnity insurance cover third-party claims.
• Incident reporting: RIDDOR requires reporting of certain workplace accidents. Prompt investigation and remedial action demonstrate reasonable care.
• Documentation: Maintain maintenance logs, training records, and safety inspections. In Wade v CN Rail, lack of inspection records contributed to a finding of negligence.

Case Study: Corporate Negligence

Case Law: Caparo Industries plc v Dickman 2 AC 605
View Case: Caparo v Dickman
Caparo bought shares in a company relying on audited accounts that overstated profits. The House of Lords held auditors owed no duty of care to investors who relied on accounts for takeover purposes. The three-stage test for duty was affirmed: foreseeability, proximity, and whether it is fair, just, and reasonable to impose a duty. The case limits liability for pure economic loss to cases where the defendant assumed responsibility to the claimant.

FAQ

Is negligence the same as carelessness?

Not exactly. Carelessness is a fact. Negligence is a legal conclusion that the carelessness breached a duty of care owed to the claimant and caused damage. All negligence involves carelessness, but not all carelessness is actionable negligence if there is no duty or damage.

Can I claim for emotional distress?

Claims for pure psychiatric injury require the claimant to be a primary or secondary victim. Primary victims are directly involved. Secondary victims must have close ties of love and affection, proximity to the event, and sudden shock. In Alcock v Chief Constable of South Yorkshire Police, relatives watching a disaster on TV were denied claims because they lacked proximity.

Do disclaimers prevent negligence claims?

Not for death or personal injury. The Unfair Contract Terms Act 1977 makes it impossible to exclude liability for death or personal injury caused by negligence. For other loss, exclusion clauses must be reasonable and brought to the other party’s attention. In Hedley Byrne, a disclaimer was effective to avoid liability for negligent misstatement.

What is res ipsa loquitur?

“The thing speaks for itself.” It allows an inference of negligence where the accident would not normally occur without negligence, the instrument was under the defendant’s control, and the claimant did not contribute. In Scott v London & St Katherine Docks, bags of sugar fell from a warehouse. The court inferred negligence because barrels do not fall without carelessness.
