Learn how liability is apportioned in public liability claims in England and Wales, including contributory negligence under the Law Reform (Contributory Negligence) Act 1945, contribution between multiple defendants under the Civil Liability (Contribution) Act 1978, and practical examples of shared responsibility in negligence cases.
When someone brings a public liability claim in England and Wales, liability is not always straightforward. Accidents often involve multiple parties, or the injured person may have contributed to their own harm. The legal system has frameworks to apportion liability, ensuring that responsibility for loss or injury is distributed fairly based on each party's role. This article explains how liability is apportioned, including contributory negligence, multiple defendants, and how courts allocate responsibility in public liability cases.
Understanding Liability in Public Liability Claims
In public liability claims, a claimant must normally prove that the defendant owed a duty of care, that duty was breached, and the breach caused injury or loss. However, liability can be shared where:
- The claimant contributed to their own injury; or
- More than one defendant is responsible for causing harm.
These scenarios affect how damages (compensation) are calculated and who ultimately pays.
Contributory Negligence: Sharing Blame with the Claimant
Legal Basis
Under the Law Reform (Contributory Negligence) Act 1945, if a claimant's own negligence contributed to their injury or loss, the court can reduce damages rather than bar the claim entirely. Before this Act, any claimant at fault risked losing their entire claim.
How It Works
If the defendant proves that the claimant failed to take reasonable care for their own safety and that this contributed to the harm, the court will assess what proportion of the responsibility lies with the claimant. Damages are then reduced “to such extent as the court thinks just and equitable” based on that percentage.
For example, if a claimant's compensation would otherwise be £100,000 but the court finds the claimant 25 % responsible for their own loss, the award might be reduced to £75,000.
Factors the Court Considers
In deciding contributory negligence, courts look at:
- Whether the claimant failed to take reasonable care of their own safety;
- Whether that failure played a causal role in the injury; and
- What is fair and equitable in the circumstances.
Liability reduction is discretionary and depends on the specific facts of each case.
Multiple Defendants and Contribution Between Parties
Joint and Several Liability
In some public liability claims, two or more defendants may each be responsible for the same injury or loss. Under English law, especially in joint tortfeasor situations such as multiple occupiers or different organisations responsible for the same hazard, each defendant may be jointly and severally liable. This means the claimant can recover the full amount of damages from any one defendant.
Contribution Between Defendants
While the claimant can pursue full compensation from one defendant, those defendants may seek contribution from each other under the Civil Liability (Contribution) Act 1978. This Act allows parties who have paid compensation to another party to claim part of that cost back from co‑defendants who share responsibility for the same damage.
For example, if two companies are held liable for a hazard in a public place and one pays the entire award to the claimant, that defendant can ask the court to decide how liabilities should be shared between them. The court then decides what is “just and equitable” proportionate liability among them.
This mechanism helps ensure that each defendant pays a share of the compensation that reflects their involvement in causing the harm, even if the claimant sues only one of them.
Apportionment in Cases Involving Claimant Fault and Multiple Defendants
When both contributory negligence and multiple defendants are at play, the court separates these issues:
- Establish total damages without considering contributory negligence;
- Allocate liability among defendants where appropriate using contribution rules; and
- Reduce the claimant's recoverable damages based on their share of fault.
Case law illustrates that courts must avoid combining approaches in a way that conflates claimant and defendant responsibility, and each factor is handled systematically.
Practical Examples
Example 1: Contributory Negligence
A pedestrian trips on a defective pavement but was looking at their phone and not paying attention. The council may be liable for failing to maintain the pavement, but the court might find the pedestrian partly to blame for not watching where they were going. The damages awarded would be reduced accordingly.
Example 2: Multiple Defendants
A public park accident occurs where both the local authority and a third‑party contractor share responsibility for a hazardous surface. A claimant can pursue full compensation from either, but the responsible parties can then seek contribution between them to allocate their respective shares of fault.
Time Limits for Contribution Claims
A contribution claim under the Civil Liability (Contribution) Act 1978 generally must be brought within two years from when a defendant was ordered or agreed to pay compensation. This is separate from the main limitation period for the claimant's personal injury claim.
Common Questions
Does Apportionment Affect the Claimant's Right to Sue?
No. A claimant's right to pursue their claim does not disappear merely because they contributed to their injury; liability is instead adjusted to reflect shared responsibility.
Can a Defendant Avoid Liability Entirely Because the Claimant Was Partly at Fault?
Not typically. Contributory negligence reduces damages but does not usually bar a claim unless the claimant's fault is so significant that it outweighs the defendant's breach in causing the injury. The court decides what is “just and equitable”.
What Happens If a Defendant Cannot Pay?
If the claimant has recovered full compensation from one defendant and that defendant is unable to recover contribution from co‑defendants, the claimant's compensation is not affected. The law ensures the claimant is not penalised because a defendant is insolvent or unreachable.
Key Takeaways
Apportioning liability in public liability claims ensures that responsibility for injury or loss is allocated fairly based on each party's degree of fault. The Law Reform (Contributory Negligence) Act 1945 permits courts to reduce damages when claimants share blame. The Civil Liability (Contribution) Act 1978 provides a mechanism for defendants who are jointly liable to seek contribution from one another. Both statutory frameworks operate alongside general negligence principles and help ensure that compensation awards reflect the realities of fault, whether arising from multiple responsible parties or shared responsibility between claimant and defendants.
