Model Answer
0 min readIntroduction
Negligence, a cornerstone of tort law, arises when an individual’s conduct falls below the standard of care reasonably expected of a prudent person, resulting in harm to another. It is not merely about causing harm, but about causing harm through a failure to exercise reasonable care. The principle of ‘res ipsa loquitur’ (the thing speaks for itself) often aids in establishing negligence where the accident itself suggests negligence. However, even if all elements of negligence are present, liability will not attach unless a sufficient causal link exists between the negligent act and the resulting damage. This causal link, often referred to as the ‘chain of causation’, must remain intact for a successful negligence claim.
Essentials of Negligence
To establish negligence, a plaintiff must prove the following three essential elements:
- Duty of Care: The defendant must owe a legal duty to exercise reasonable care towards the plaintiff. This duty arises when the defendant’s conduct could foreseeably cause harm to the plaintiff. The landmark case of Donoghue v Stevenson [1932] AC 562 established the ‘neighbour principle’, defining duty of care as owing a duty to those who are so closely and directly affected by one’s acts that one ought reasonably to contemplate them.
- Breach of Duty: The defendant must have breached that duty of care by failing to meet the required standard. This is assessed objectively – would a reasonable person in the defendant’s position have acted differently? In Barlow v Steel [1959] 1 WLR 1278, the court held that the standard of care is that of a reasonably prudent person, not a perfect one.
- Damage: The plaintiff must have suffered actual damage or harm as a result of the breach. This damage can be physical injury, property damage, or economic loss.
The Chain of Causation
Even if the above three elements are established, the plaintiff must also prove that the defendant’s breach of duty was the proximate cause of the damage. This is where the ‘chain of causation’ comes into play. The chain must remain intact, meaning there should be no novus actus interveniens (a new intervening act) that breaks the causal link between the defendant’s negligence and the plaintiff’s harm.
Types of Causation
- Factual Causation (“But For” Test): This test asks whether, ‘but for’ the defendant’s negligence, the harm would not have occurred. Established in Barnett v Chelsea & Kensington Hospital Management Committee [1968] 1 QB 428, this test is a preliminary step.
- Legal Causation (Proximate Cause): Even if factual causation is established, legal causation must also be proven. This involves determining whether the damage was a reasonably foreseeable consequence of the defendant’s negligence.
Intervening Acts & Breaking the Chain
An intervening act can either be:
- Independent Intervening Act: A completely independent act that breaks the chain of causation, relieving the defendant of liability.
- Dependent Intervening Act: An act that occurs as a result of the defendant’s negligence. Whether this breaks the chain depends on its foreseeability.
In McKew v Holland [1969] 1 WLR 1608, the defendant’s negligence in failing to provide adequate lighting led to a man suffering a heart attack while attempting to descend stairs. The court held that the heart attack was not a reasonably foreseeable consequence of the lack of lighting, and therefore the chain of causation was broken.
However, in Josephine M v Vacwell Engineering Ltd [1998] 1 WLR 346, it was held that a negligent medical treatment did not necessarily break the chain of causation if it was a reasonably foreseeable consequence of the initial negligence.
Remote Consequences: The Wagon Mound (No. 1) [1961] AC 388 established that even if damage is foreseeable, the defendant is not liable for damage that is too remote. The damage must be of a kind that a reasonable person would contemplate as a possible result of the negligence.
Illustrative Table
| Element of Negligence | Description | Relevant Case Law |
|---|---|---|
| Duty of Care | Obligation to exercise reasonable care to avoid harming others. | Donoghue v Stevenson [1932] AC 562 |
| Breach of Duty | Failure to meet the standard of care. | Barlow v Steel [1959] 1 WLR 1278 |
| Damage | Actual harm suffered by the plaintiff. | N/A (Damage is a factual element) |
| Causation | A direct link between the breach and the damage. | Barnett v Chelsea & Kensington Hospital Management Committee [1968] 1 QB 428, McKew v Holland [1969] 1 WLR 1608 |
Conclusion
In conclusion, establishing negligence requires proving a duty of care, a breach of that duty, and resulting damage. However, the crucial element of causation dictates that the chain linking the negligence to the damage must remain unbroken. Intervening acts and the remoteness of damage can sever this chain, absolving the defendant of liability. Understanding the nuances of causation, as illustrated by the case laws discussed, is paramount in successfully pursuing or defending a negligence claim. The principle ensures fairness by holding individuals accountable only for the consequences that are reasonably foreseeable from their actions.
