Theory of Tort Law (AQA A-Level Law): Revision Notes
Policy decisions
Understanding policy decisions in tort law
When judges develop the common law of negligence, they must decide whether to impose liability in situations that have not been previously addressed by the courts. These decisions are known as policy decisions.
Policy decisions are not made simply to achieve justice for the individual parties in a particular case. Instead, judges aim to create a precedent that is fair, just and reasonable for future cases. This requires careful consideration to avoid creating an overwhelming number of new claims (often described as "opening the floodgates").
The law of negligence is primarily common law, meaning it has been developed through judicial decisions over time rather than through Acts of Parliament. This gives judges significant responsibility when deciding whether to extend liability into new areas.
This content will be assessed in Paper 2.
Factors judges consider when determining duty of care
When deciding whether to impose a duty of care in a new situation, judges take into account three main policy considerations:
The Three Key Policy Factors (LFP):
The courts consider three interconnected factors when making policy decisions about duty of care: Loss allocation, Floodgates, and Practical impact.
Loss allocation
Judges consider which party is better able to bear the financial loss. Key questions include:
- Who can afford to pay compensation?
- Does either party have insurance coverage?
- Is either party funded by taxpayers (such as public bodies)?
The principle behind this factor is that it may be fairer to place liability on a party that can more easily absorb or distribute the financial burden, particularly through insurance mechanisms.
Floodgates
Judges assess whether imposing liability would lead to a large volume of new claims. They consider:
- The potential impact on the insurance industry
- The burden on the court system
- The effect on public-funded bodies and essential services
If recognizing a duty of care in one case would open the floodgates to countless similar claims, judges may be reluctant to impose liability.
Practical impact
Judges examine the real-world consequences of imposing liability, including:
- Whether it will raise standards and deter negligent behavior
- Whether it might divert essential funds away from front-line services
- Whether public bodies would become overly defensive in their operations
For example, if imposing liability on the police would cause them to spend more resources defending legal claims than actually preventing crime, this would be a significant practical concern.
Policy decisions and public-funded bodies
Policy considerations are particularly important when claims involve public-funded bodies, including:
- The police
- The Crown Prosecution Service (CPS)
- Local authorities
- Emergency services
These bodies are funded by taxpayers and provide essential public services. Judges must carefully balance the rights of individuals to claim compensation against the potential impact on these vital services.
Key case law on public bodies
Caparo v Dickman (1990) established the three-part test for duty of care, which includes the requirement that imposing a duty must be fair, just and reasonable. This explicitly incorporates policy considerations into the duty of care analysis.
Hill v Chief Constable of West Yorkshire (1988) initially suggested that the police might have limited liability for negligence in investigating crime, based partly on policy grounds.
Michael v Chief Constable of South Wales (2015) continued the discussion about police liability and policy factors.
Robinson v Chief Constable of West Yorkshire (2018) - Critical Clarification
Lord Reed emphasized that Hill does NOT mean:
authority for the proposition that the police enjoy a general immunity from suit in respect of anything done by them in the course of investigating or preventing crime [and in fact] the liability of the police for negligence or other tortious conduct resulting in personal injury, where liability would arise under ordinary principles of the law of tort, was expressly confirmed.
This demonstrates that policy considerations should not create blanket immunities for public bodies. Instead, they inform the careful development of the law.
In the same case, Lord Mance acknowledged the role of policy in developing tort law:
It would be unrealistic to suggest that, when recognising and developing an established category, the courts are not influenced by policy considerations... Landmark examples are Donoghue v Stevenson ... in relation to physical injury, and Hedley Byrne & Co Ltd v Heller & Partners Ltd [in relation to economic loss].
Policy decisions relating to pure economic loss
Pure economic loss refers to financial loss that is not accompanied by physical injury or property damage. For example, lost profits or wasted expenditure.
The courts have adopted a restrictive approach to claims for pure economic loss, based on important policy reasons. If such claims were widely actionable, there would be no reasonable limit to a defendant's liability, potentially overwhelming the court system.
The problem of indeterminate liability
Cardozo's Famous Warning - Ultramares v Touche (1931)
US Judge Benjamin N. Cardozo famously described the concern about unrestricted pure economic loss claims as:
a fear of an indeterminate number of claims by an indeterminate number of parties in indeterminate amounts of money for an indeterminate amount of time.
This perfectly expresses the floodgates concern - a single negligent act could give rise to claims from countless parties, for unpredictable amounts, extending indefinitely into the future.
Practical Example: The Cascading Effect of Economic Loss
If a manufacturer negligently produces a defective product, this could lead to financial losses for:
- Suppliers (reduced orders)
- Retailers (unsold stock)
- Consumers (wasted expenditure)
- Competitors (market disruption)
- Many others in the supply chain
Without restrictions, the manufacturer could face limitless liability from an ever-expanding circle of affected parties.
Establishing liability for pure economic loss
Because of these policy concerns, claimants can only recover pure economic loss in limited circumstances. The key case is Hedley Byrne and Co. Ltd v Heller and Partners Ltd (1963), which established that pure economic loss can be recovered where there is a special relationship between the parties, typically involving an assumption of responsibility.
Policy decisions relating to psychiatric injury
Psychiatric injury (also called nervous shock) refers to recognized psychiatric conditions caused by the defendant's negligence, such as post-traumatic stress disorder or clinical depression.
The courts have historically treated psychiatric injury differently from physical injury, based on several policy concerns. While modern understanding recognizes that psychiatric injury can be just as serious as physical harm, the law continues to restrict these claims.
Policy reasons for restricting psychiatric injury claims
Three Key Concerns About Psychiatric Injury Claims (FFP):
The courts have identified three main policy concerns that justify restricting psychiatric injury claims: Floodgates, Fraud, and Problems of proof.
Floodgates
Courts have worried that allowing widespread recovery for psychiatric injury would open the floodgates to numerous claims. Unlike physical injury, psychiatric harm can affect many people who witness or learn about a traumatic event, potentially leading to countless claimants.
Fraudulent claims
There has been concern about the potential for people to exaggerate or fabricate psychiatric symptoms. While this concern may be overstated and somewhat outdated, it has historically influenced judicial thinking.
Problems of proof and diagnosis
Psychiatric injury can be difficult to prove and diagnose objectively. Unlike a broken bone that can be seen on an X-ray, psychiatric conditions require expert medical opinion. This increases the cost and complexity of litigation, and creates uncertainty about the validity of claims.
Secondary victims
In many psychiatric injury cases, the claimant is a secondary victim - someone who suffers psychiatric harm as a result of witnessing injury to another person, rather than being directly involved in the incident themselves.
Secondary Victim Scenario
A parent who witnesses their child being injured in an accident might suffer post-traumatic stress disorder. The parent is a secondary victim because they were not directly involved in the incident but suffered psychiatric harm from witnessing it.
The law imposes strict requirements on when secondary victims can recover, largely based on policy concerns about opening the floodgates.
Parliamentary intervention
Courts have also suggested that Parliament is better suited to deal with psychiatric injury claims than the judiciary. This is because comprehensive reform might be needed to balance competing interests, which is more appropriately done through legislation than incremental common law development.
Key cases
McLoughlin v O'Brian (1983) allowed a mother to recover damages for psychiatric injury after seeing her family in hospital following an accident. This case demonstrated some expansion of liability for psychiatric injury, but within controlled limits.
Alcock v Chief Constable of South Yorkshire (1992) established strict requirements for secondary victims claiming psychiatric injury. The case arose from the Hillsborough disaster and set out detailed criteria that must be met, reflecting the policy concerns about indeterminate liability.
The objective standard of care and policy
The test for breach of duty in negligence uses an objective standard - the standard of the reasonable person. This is partly a policy decision.
Vaughan v Menlove (1837) established this principle. The defendant built a haystack near his property boundary, adjacent to the claimant's land. The haystack caught fire and spread to the claimant's barns, stables and cottages. The defendant argued he had acted to the best of his own judgment.
The court rejected a subjective test (based on the defendant's own abilities) and adopted an objective standard:
If the standard was that the defendant only needed to act "bona fide to the best of his own judgement", that would leave so vague a line as to afford no rule at all, the degree of judgement belonging to each individual being infinitely various. We ought to adhere to a standard which requires in all cases a regard to caution such as a man of ordinary prudence would observe.
Policy reasons for the objective standard
Why an Objective Standard? Four Key Policy Benefits:
Using an objective standard rather than a subjective one serves important policy purposes:
- Certainty: It provides a clear, predictable standard that applies to everyone
- Fairness: Everyone is judged by the same standard regardless of their individual capabilities
- Protection: It protects potential victims by ensuring a minimum standard of care
- Consistency: It prevents endless variation based on individual circumstances
A subjective test would create uncertainty and make the law difficult to apply consistently. It would also potentially allow defendants with poor judgment to escape liability.
Injunctions: balancing conflicting interests
An injunction is a court order that prohibits a person from doing something (prohibitory injunction) or requires a person to do something (mandatory injunction). Injunctions are commonly used as remedies in nuisance and trespass cases.
Legal basis for granting injunctions
The Supreme Court of Judicature Act 1925 (now repealed but still representing the legal principle) stated in section 45:
an injunction may be granted ... in all cases in which it shall appear to the Court to be just or convenient.
This gives courts discretion to grant injunctions based on what is fair and appropriate in the circumstances.
Balancing exercise
The Balancing Act
When deciding whether to grant an injunction, courts must balance competing interests. They weigh:
- The social usefulness of the defendant's activity
- The harm the activity is causing to the claimant
This balancing exercise involves policy considerations about what benefits society as a whole, not just the immediate parties to the case.
Key cases on injunctions
Miller v Jackson (1977) involved cricket balls being hit into a claimant's property from a nearby cricket ground. The majority of the Court of Appeal refused to grant an injunction, considering the social value of the cricket club to the local community.
Kennaway v Thompson (1981) involved noise from powerboat racing on a lake disturbing the claimant's property. The Court of Appeal granted an injunction with specific restrictions, demonstrating a different approach to balancing the interests.
These cases show that courts must carefully consider policy factors when deciding remedies, not just when establishing liability.
Vicarious liability: policy rationale
Vicarious liability is a form of strict liability where one person is held legally responsible for the torts of another, even though they did not commit the tort themselves.
The most common form is employer liability for torts committed by employees in the course of their employment. To establish vicarious liability, it must be shown that:
- The wrongdoer was an employee (not an independent contractor)
- The tort was committed in the course of employment (there must be a sufficient connection between the employment duties and the wrongful act)
The "deepest pockets" policy
The Core Policy Rationale: "Deepest Pockets"
The primary policy reason for vicarious liability is that employers typically have the "deepest pockets" - meaning they have greater financial resources than individual employees.
This policy rationale has several aspects:
- Compensation: Employers are more likely to be able to pay substantial compensation to injured claimants
- Insurance: Most employers carry insurance against vicarious liability, spreading the risk across many premium payers
- Risk distribution: Employers can distribute the cost of compensation through prices charged to customers
- Loss spreading: It is fairer to spread losses across a business (and ultimately society through prices and insurance) than to leave them on individual victims
Encouraging high standards
Vicarious liability also serves a deterrent function. By making employers liable for their employees' torts, the law encourages employers to:
- Hire competent employees
- Provide proper training and supervision
- Implement safe systems of work
- Monitor employee conduct
Key cases
Ready Mixed Concrete Ltd v Minister of Pensions (1968) established a test for determining employment status, which is crucial for vicarious liability. The case set out factors to consider when deciding if someone is an employee or an independent contractor.
Mohamud v WM Morrison Supermarkets plc (2016) addressed when an employee's actions are "in the course of employment". The Supreme Court held that an employer could be vicariously liable for an employee's assault on a customer, even though the assault was a prohibited act, because there was a sufficient connection with the employee's work duties.
Exam guidance
Policy decisions are fundamental to understanding how tort law develops and operates. When answering exam questions:
Analysis questions might ask you to:
- Explain the policy factors that influence judicial decisions
- Analyze how policy concerns have shaped particular areas of tort law
- Discuss the relationship between policy and precedent
Evaluation questions might ask you to:
- Assess whether the courts strike the right balance between competing interests
- Evaluate whether policy factors are applied consistently
- Consider whether judges or Parliament are best placed to develop tort law
Application questions require you to:
- Apply policy considerations when analyzing whether a duty of care should exist
- Consider policy factors when discussing whether liability should be imposed
- Make links between policy decisions and the substantive law of tort
Always support your answers with relevant case law and demonstrate understanding of how policy factors influence legal development.
Remember!
Key Points to Remember:
-
Policy decisions help judges create fair, just and reasonable precedents when developing tort law, particularly in new areas of liability
-
The three main policy factors are loss allocation (who can bear the loss), floodgates (volume of potential claims), and practical impact (real-world consequences) - remember LFP
-
Pure economic loss is restricted to prevent indeterminate liability - Cardozo's famous phrase captures the concern about unlimited claims by unlimited parties for unlimited amounts
-
Psychiatric injury claims are limited due to floodgates concerns, fears of fraud, and difficulties with proof (FFP), though modern law recognizes psychiatric harm can be as serious as physical injury
-
The objective standard (reasonable person test) serves policy goals of certainty, fairness and consistency in negligence law
-
Injunctions require courts to balance the social usefulness of activities against harm to claimants
-
Vicarious liability exists primarily because employers have the "deepest pockets" and can better compensate victims through insurance and risk spreading
