Welcome to the World of Defences!
In your study of the Law of Tort, you have already learned how a claimant can prove that a defendant is liable for things like negligence or nuisance. But wait—is it always 100% the defendant's fault? Sometimes, the defendant has an "excuse" or a legal reason why they shouldn't have to pay the full amount (or anything at all!). These are called Defences.
Think of it like a sports match: if the claimant is "on the attack" trying to score a win (compensation), the defendant uses "defences" to block that attack. In this chapter, we will look at the different shields a defendant can use in a Tort case.
1. General Defences: Contributory Negligence
Contributory Negligence is a partial defence. This means it doesn't get the defendant off the hook completely, but it reduces the amount of money (damages) they have to pay.
What is it?
It happens when the claimant helped cause their own injuries by failing to take reasonable care of themselves. The judge will look at the accident and decide: "What percentage of this was the claimant's own fault?"
How it works:
If the judge decides the claimant was 25% responsible for their injuries, the defendant only pays 75% of the compensation. This is governed by the Law Reform (Contributory Negligence) Act 1945.
Real-World Examples:
- Failing to wear a seatbelt: If you are injured in a car crash that wasn't your fault, but your injuries are worse because you didn't wear a seatbelt, your compensation will be reduced (Froom v Butcher).
- Failing to wear a helmet: A motorcyclist or cyclist not wearing a helmet may have their damages reduced.
- Accepting a lift from a drunk driver: If you know the driver is drunk and get in the car anyway, you are contributing to your own risk (Owens v Brimmell).
Don't worry if this seems tricky: Just remember it's like a "blame pie." The judge cuts the pie into slices of blame for the defendant and the claimant!
Quick Review: Contributory Negligence
Type: Partial Defence (Reduces the money).Key Point: The claimant was partly to blame for their own harm.
Mistake to Avoid: Do not say the defendant is "innocent." They are still liable, just for less money!
2. General Defences: Volenti non fit injuria (Consent)
This is a complete defence. If the defendant wins this argument, they pay zero compensation. The Latin phrase Volenti non fit injuria roughly translates to: "To one who is willing, no harm is done."
The Three Rules of Consent:
For this defence to work, the defendant must prove the claimant:
- Had knowledge of the precise risk involved.
- Exercised free will (they weren't forced).
- Voluntarily accepted the risk.
An Everyday Analogy:
Imagine you decide to join a "Tomato Throwing Festival." You know people are throwing tomatoes, you chose to go there, and you walked into the splash zone. You can't later sue someone for staining your white t-shirt—you consented to the risk of getting hit by a tomato!
Important Case: Wooldridge v Sumner
A photographer at a horse show stood inside the ring. A horse went out of control and injured him. The court ruled that by being there, he accepted the risks of the sport. The defendant was not liable.
Did you know? This defence rarely works for passengers in car accidents. Because of the Road Traffic Act 1988, drivers cannot use "consent" as a defence to avoid paying for injuries to their passengers, even if the passenger knew the driver was drunk.
Key Takeaway: Consent
Type: Complete Defence (Defendant pays £0).Mnemonic: K.F.V. — Knowledge, Free will, Voluntary acceptance.
3. Defences for Private Nuisance
When someone is sued for Private Nuisance (interfering with someone's use or enjoyment of their land), they have specific "shields" they can use.
Statutory Authority
This is the strongest defence. If a Statute (an Act of Parliament) gave the defendant permission to carry out the activity, they are usually not liable for the nuisance it causes. For example, if Parliament passes a law to build a new railway, the noise of the trains is "authorized" by law.
Prescription
This is a bit strange! If a defendant has been doing the "nuisance" activity for at least 20 years against the same claimant without them complaining, they earn the right to keep doing it. It’s like a "squatter's right" for noise or smells.
Common Mistake: "Coming to the Nuisance"
Students often think that if a claimant moves next door to a noisy factory, they can't complain because "they knew it was there." This is WRONG. Moving to a nuisance is not a defence (Miller v Jackson). The claimant still has a right to enjoy their land!
4. Defences for Rylands v Fletcher
You might remember Rylands v Fletcher as the "leaking reservoir" case. It deals with dangerous things escaping from land. Because this is "Strict Liability" (you are responsible even if you weren't "careless"), the defences are very specific:
1. Act of a Stranger
If the escape was caused by the deliberate and unforeseeable act of someone the defendant had no control over, the defendant isn't liable. (Example: A vandal breaks your pipes and causes a flood).
2. Act of God
This is for extreme natural events that no one could have predicted, like a "once in a century" thunderstorm or earthquake (Nichols v Marsland).
3. Consent
If the claimant agreed to the dangerous thing being kept on the land (especially if it benefits both of them), they cannot sue if it escapes.
4. Statutory Authority
Just like in nuisance, if an Act of Parliament requires the defendant to store the substance, they are protected.
Quick Review: Rylands Defences
Act of Stranger: Someone else did it.Act of God: Nature did it (and it was huge!).
Statutory Authority: The law said I had to do it.
Summary Checklist
Before you finish, make sure you can answer these three questions:
- Which defence is partial (only reduces the money)? (Answer: Contributory Negligence)
- Which defence requires the K.F.V. rules? (Answer: Volenti/Consent)
- Is "moving next door to a smell" a valid defence? (Answer: No!)
Keep going! Defences can be a lot to memorize, but once you see them as "common sense" excuses, they become much easier to apply to exam scenarios.
