Negligence and Nuisance under the Law of Torts

Updated 11 October 2026 · Fact-checked

Negligence is breach of a legal duty of care that causes damage to the plaintiff. Nuisance is an unreasonable interference with the use or enjoyment of land, or with a public right. To solve a question, identify the tort, test each essential against the facts, check defences, and conclude.

Understand Negligence and Nuisance

A tort is a civil wrong for which the law gives damages. Negligence and nuisance are two of the most tested torts in this chapter.

Negligence means failing to take the care that a reasonable person would take. It is not just careless behaviour. It becomes a tort only when three things are present: the defendant owed the plaintiff a duty of care, the defendant breached it, and the plaintiff suffered damage because of that breach. The test of duty comes from Donoghue v Stevenson (the snail-in-the-bottle case): you owe a duty to your 'neighbour', meaning anyone you can reasonably foresee would be affected by your act. The standard of care is that of a reasonable, prudent person. A professional is judged by the skill of an ordinary competent member of that profession.

Proof of negligence is normally on the plaintiff. Res ipsa loquitur ('the thing speaks for itself') helps when the cause of the accident is wholly in the defendant's control and the accident would not ordinarily happen without negligence. The court then infers negligence, and the defendant must explain. It does not change the burden of proof in law. It only lets the court draw an inference from the facts. Byrne v Boadle (a barrel falling from a warehouse window) is the standard illustration.

Contributory negligence is where the plaintiff's own lack of care helped cause the harm. Under the common law rule the plaintiff could recover nothing. The modern approach, followed in India, is to reduce the damages in proportion to the plaintiff's share of fault. The rule of last opportunity (Davies v Mann, the donkey case) applies when the defendant could have avoided the accident at the last moment despite the plaintiff's earlier fault. In that case the defendant is fully liable.

Nuisance is an unlawful interference with a person's use or enjoyment of land, or with some right over it. Private nuisance affects a particular person's land or enjoyment of it. It is actionable by the occupier, and the interference must be unreasonable, judged by locality, duration, intensity and sensitivity. Damage must be proved, except where the interference materially affects the plaintiff's property (for example, physical damage to property). Public nuisance affects the public or a class of people, such as blocking a highway or polluting a common water source. An individual can sue for it only if they suffer special damage beyond what the public suffers. In India public nuisance is also a crime under the Bharatiya Nyaya Sanhita.

Nuisance differs from trespass. Trespass is a direct, physical entry onto land and is actionable per se, with no proof of damage. Nuisance is an indirect interference, such as smoke, noise or smell, and usually needs proof of damage or substantial discomfort.

Key rules to remember

Essentials of negligence: Duty of care + Breach of that duty + Damage caused by the breach = Negligence; All three must be proved. Damage must also be a reasonably foreseeable result, not too remote.
Res ipsa loquitur conditions: Thing under defendant's control + Accident not ordinarily happening without negligence + Cause unknown to plaintiff = Inference of negligence; It shifts the practical need to explain to the defendant. It does not apply if the accident has an equally likely innocent explanation.
Contributory negligence effect: Damages payable = Total loss − Share of loss attributable to the plaintiff's own fault; Apportionment is the modern rule. The last opportunity rule can make the defendant fully liable.
Private nuisance test: Unreasonable interference with enjoyment of land + Damage (or material injury to property) = Private nuisance; Reasonableness depends on locality, duration, intensity and the plaintiff's sensitivity. Ordinary people's comfort is the yardstick.
Public nuisance action: Act affecting the public + Special damage to the plaintiff = Private action for public nuisance; Without special damage, the remedy lies with public authorities or in a suit with proper permission.
Nuisance vs trespass: Trespass = direct physical entry, actionable per se. Nuisance = indirect interference, damage generally needed.; Use this one-line contrast in any 'differentiate' question.

How to solve Negligence and Nuisance questions

Use the same sequence for every problem question on negligence or nuisance. It matches the ICSI answer style: provision, analysis, conclusion.

1Identify the tort the facts point to. Careless act causing injury suggests negligence. Smoke, noise, smell or obstruction suggests nuisance. Direct physical entry suggests trespass.
2State the rule in one or two lines: the essentials of the tort you chose.
3For negligence, test duty of care first. Ask whether the plaintiff was a reasonably foreseeable victim, then ask what a reasonable person would have done.
4Test breach, then damage and causation. Note whether the harm is too remote.
5For nuisance, decide if it is private or public. Check unreasonableness (locality, duration, intensity), damage, and in public nuisance, special damage.
6Check whether res ipsa loquitur applies, and whether there is contributory negligence or a defence such as statutory authority, prescription or consent.
7Apply each point to the facts using the names and figures in the question. Do not just repeat the law.
8Write a clear conclusion: is the defendant liable, and if damages are reduced, say so.

Quickest way: Three-line scan: Duty, Breach, Damage

When to use it: Use it when you have under ten minutes for a problem question, or when you must decide the tort quickly.

Underline the act, the injured person and the harm in the question.
Write 'Duty – Breach – Damage' for negligence, or 'Interference – Unreasonable – Damage' for nuisance, and tick each against the facts.
Add one line on res ipsa loquitur, contributory negligence or special damage if the facts hint at it, then write the conclusion.

Common mistakes in Negligence and Nuisance

Treating every careless act as negligence without checking duty of care.
Students focus on the carelessness and forget that the law needs a legal duty owed to that plaintiff.
Fix: Always write the duty step first and use the neighbour principle: was the plaintiff a foreseeable victim?
Saying res ipsa loquitur reverses the burden of proof completely.
The phrase 'speaks for itself' sounds like automatic liability.
Fix: Say that it lets the court infer negligence. The defendant must give a reasonable explanation, and may escape if they do.
Writing that contributory negligence is a complete defence that bars all damages.
Students remember the old common law rule only.
Fix: State that damages are now reduced in proportion to the plaintiff's fault. Mention the last opportunity rule as the exception that can make the defendant fully liable.
Confusing nuisance with trespass.
Both involve land, and both can come from a neighbour.
Fix: Remember: trespass is direct and physical, actionable without damage. Nuisance is indirect, and needs unreasonable interference and damage.
Giving a private remedy for public nuisance without special damage.
Students assume any affected person can sue.
Fix: Check whether the plaintiff suffered harm different in kind from the general public. If not, a private action fails.
Ignoring locality and sensitivity in nuisance problems.
Students jump to 'noise is a nuisance'.
Fix: Discuss locality, duration, intensity and whether the plaintiff is unusually sensitive. Ordinary comfort is the test, not special delicacy.

Worked examples

Example 1

Ravi, a pedestrian, is walking past a building under repair in Pune. A sack of cement falls from the scaffolding and injures him. The contractor, Mehta Constructions, says Ravi cannot prove how the sack fell. Advise Ravi.

Show the solution

Rule: negligence needs duty of care, breach and damage. Where the plaintiff cannot show the exact cause, res ipsa loquitur may allow the court to infer negligence.
Duty: a contractor working above a public pavement owes a duty to passers-by, who are foreseeable victims.
Breach: the scaffolding and sack were wholly under the contractor's control. A sack does not ordinarily fall if proper care is taken, so the facts point to negligence.
Res ipsa loquitur: all conditions are met, so Ravi need not prove the exact cause. The contractor must give a reasonable explanation of how the accident happened without negligence.
Damage: Ravi suffered injury directly from the fall, so damage and causation are satisfied.

Answer: Mehta Constructions is likely liable in negligence. Res ipsa loquitur applies, and unless the contractor shows a satisfactory non-negligent explanation, Ravi can recover damages for his injury.

Example 2

A factory in an industrial area of Ludhiana emits foul-smelling fumes. Sunita, who lives in a nearby house, suffers headaches and cannot sit in her garden. Other residents are affected too. Discuss the remedies available to Sunita and how this differs from trespass.

Show the solution

Identify the tort: fumes and smell interfere with the use and enjoyment of Sunita's land without any physical entry by a person. This points to nuisance.
Private nuisance: the interference must be unreasonable, judged by locality, duration and intensity. The fact that the area is industrial counts in the factory's favour, but a smell that causes physical discomfort to ordinary people may still be unreasonable.
Damage: Sunita has suffered real discomfort and loss of enjoyment of her home, which is the kind of damage nuisance protects.
Public nuisance: because many residents are affected, it may also be a public nuisance. Sunita can sue personally only if she shows special damage beyond that of the general public, for example illness requiring treatment.
Remedies: damages, an injunction to stop the fumes, and abatement in suitable cases.
Difference from trespass: trespass is a direct physical entry on land and is actionable without proof of damage. Here the interference is indirect, so damage must be shown.

Answer: Sunita can sue for private nuisance if the fumes are unreasonable despite the industrial locality, and can claim damages and an injunction. For public nuisance she needs special damage. The wrong is nuisance, not trespass, because there is no direct physical entry.

Exam tips

For problem questions, always name the tort first and then list the essentials. ICSI answers earn marks for the provision, the analysis and the conclusion.
Learn short case illustrations: Donoghue v Stevenson for duty of care, Byrne v Boadle for res ipsa loquitur, Davies v Mann for last opportunity. Use only those you are sure of.
In 'differentiate' questions, write a point-by-point comparison (nature of interference, need for damage, directness) rather than a long paragraph.
Always add contributory negligence as a point if the injured person did anything careless. Say that damages are reduced, not denied.
End every problem answer with a one-line conclusion that names the party liable.

Practice questions from Law of Torts

Negligence and Nuisance: frequently asked questions

What are the essentials of negligence for CS Executive?

There are three: a legal duty of care owed to the plaintiff, breach of that duty, and damage caused by the breach. The damage must not be too remote. Write all three and apply each to the facts.

What is res ipsa loquitur in simple words?

It means 'the thing speaks for itself'. When an accident would not normally occur without negligence and the thing was in the defendant's control, the court infers negligence. The defendant then has to explain how it happened.

What is the difference between nuisance and trespass?

Trespass is a direct physical entry onto another's land and is actionable without proof of damage. Nuisance is an indirect interference with enjoyment of land, such as smoke or noise, and generally needs damage. Both protect land, but the nature of the interference differs.

What does contributory negligence mean?

It means the plaintiff's own lack of reasonable care contributed to the harm. The court reduces the damages in proportion to the plaintiff's share of fault. If the defendant had the last opportunity to avoid the accident, the defendant is fully liable.

When can an individual sue for public nuisance?

Only when the individual suffers special damage, meaning harm different in kind from that of the general public. Without it, public authorities take action against the nuisance.
