Elements of Tort of Negligence with Case Law

The tort of negligence is a fundamental concept in tort law that addresses situations where an individual or entity fails to exercise reasonable care, resulting in harm to another person. This area of law is designed to provide remedies for those who suffer damages due to another's lack of care or oversight. Central to establishing a claim of negligence are several key elements: duty of care, breach of duty, causation, and harm. Through the examination of these elements and relevant case law, courts assess whether a party's conduct falls below the expected standard of care and whether this lapse directly resulted in harm. Therefore, understanding these elements is crucial for navigating and adjudicating claims of negligence effectively.

Duty of Care
The first element of the tort of negligence is the establishment of a duty of care. A duty of care arises when one party is legally obligated to act in a certain way to avoid causing harm to another. This principle was firmly established in the landmark case of Donoghue v Stevenson (1932). In this case, the plaintiff, Mrs. Donoghue, became ill after drinking a ginger beer containing a decomposed snail, which she had not seen but was purchased for her by a friend. The House of Lords held that the manufacturer owed a duty of care to the ultimate consumer, even though there was no direct contractual relationship between them. This case established the foundational principle that individuals and entities owe a duty of care to those who might be foreseeably affected by their actions or omissions.

Breach of Duty
Once a duty of care is established, the next element is to prove that there was a breach of that duty. A breach occurs when a party fails to meet the standard of care expected in the circumstances. The standard is generally based on what a reasonable person would do in similar circumstances. In Blyth v Birmingham Waterworks Co (1856), the court defined negligence as the failure to do something which a reasonable person would do or doing something which a reasonable person would not do. In this case, a waterworks company was found liable for damage caused by a burst pipe that was not due to any reasonable foreseeability or negligence on their part. The court emphasised that the standard of care must be assessed by considering the actions of a reasonable person in similar circumstances.

Causation
Causation requires that the breach of duty directly led to the harm suffered by the plaintiff. There are two components to causation: factual causation and legal causation. Factual causation is usually determined by the "but for" test, which asks whether the harm would have occurred but for the defendant’s breach. Legal causation involves assessing whether it is fair and just to hold the defendant responsible for the harm. In Barnett v Chelsea & Kensington Hospital Management Committee (1969), a patient died from arsenic poisoning after being dismissed by a hospital without examination. The court found that even though the hospital had breached its duty of care, the patient would have died regardless due to the severity of the poisoning, thereby breaking the chain of causation.

Damage
For a claim in negligence to succeed, the plaintiff must demonstrate that they suffered actual damage or harm as a result of the breach. This harm must be a direct result of the defendant's actions. In The Wagon Mound (No. 1) (1961), oil spilled from a ship and caused a fire, damaging a wharf. The Privy Council ruled that while the spill was foreseeable, the specific type of damage (the fire) was not. Therefore, the defendants were not held liable for the consequential damage. This case clarified that damage must be foreseeable and a direct result of the breach to be compensable.

Foreseeability
Foreseeability is often considered in determining both the duty of care and causation elements. It involves assessing whether the harm was a predictable consequence of the defendant’s actions. In Kent v Griffiths (2000), an ambulance failed to arrive on time due to a delay, causing the plaintiff's condition to worsen. The House of Lords held that the ambulance service was liable because it was foreseeable that a delay would result in harm. This case highlighted that the harm must be within the scope of what a reasonable person would foresee as a consequence of the breach.

The tort of negligence involves several key elements: establishing a duty of care, proving a breach of that duty, showing that the breach caused the harm, and demonstrating that the harm was foreseeable and direct. Each of these elements must be satisfied for a claim of negligence to be successful. Through case law such as Donoghue v Stevenson, Blyth v Birmingham Waterworks Co, Barnett v Chelsea & Kensington Hospital Management Committee, The Wagon Mound (No. 1), and Kent v Griffiths, the principles of negligence have been developed and clarified, shaping how courts assess and determine claims in this area of law.
