General Principles of Liability in Torts

The conditions that make a person liable in tort, and the bases of liability: intention, negligence and no fault

In one minute

A defendant is liable in tort when four things come together. He did a wrongful act. It caused legal damage. The law attaches a mental element, or none, to that kind of wrong. No defence excuses him.

The mental element is the part that varies. Some torts need intention, many need only negligence, and some impose liability without fault. Examiners ask for these conditions as a long answer, so learn the list and the three bases of liability.

Usually asked as: Both (long answer and short answer)

Legal provision

No single statute lists the conditions. They come from decided cases and from the statutes on particular torts.
Section 2(m), Limitation Act, 1963: a tort is a civil wrong not exclusively a breach of contract or trust.
Statutes that fix liability: the Motor Vehicles Act, 1988 (section 164), the Consumer Protection Act, 2019 and the Public Liability Insurance Act, 1991 each impose liability on set facts.

Meaning and definition

The general principles of liability are the common conditions that decide whether a defendant must pay for a tort. They apply across torts, whatever the particular tort is.

A principle is "general" when it applies to most torts and not to one only. The specific rules of assault, nuisance or defamation then add their own special requirements.

Detailed explanation

Step 1: the conditions of liability

A wrongful act or omission. The defendant broke a duty fixed by law. A lawful act is not enough, whatever the motive.
Legal damage. A legal right of the plaintiff was violated. Loss without a violated right gives no claim (damnum sine injuria).
Causation. The act must have caused the damage. The test is factual ("but for the act, would the damage have happened?") and then legal (is the damage too remote?).
A fault element, where the tort requires it. Intention, recklessness or negligence is needed for most torts. Some torts need none.
Capacity of the parties. The plaintiff must be able to sue and the defendant to be sued. Minors, the State and companies raise special points.
No defence. Consent, necessity, private defence, statutory authority and similar defences can excuse the defendant.

Example. Ravi's lorry, driven carelessly, hits Salma's parked scooter in Guntur and wrecks it. There is a wrongful act (careless driving), legal damage (harm to her property), causation (the lorry hit the scooter), fault (negligence), and no defence. Ravi is liable.

Step 2: causation

The plaintiff must link the damage to the act. Courts ask two questions.

Factual cause. Would the damage have happened without the act? If yes, the act is not a cause.
Legal cause. Is the damage of a kind the defendant could reasonably foresee? If it is too remote, there is no liability (The Wagon Mound No. 1). A new act of a third person that breaks the chain can also free the defendant.

Step 3: the mental element

The mental element is the state of mind or standard of conduct the tort needs. It runs along a scale.

Intention. The defendant wanted the result or knew it was almost certain. Assault, battery, false imprisonment and deceit need it.
Negligence. The defendant failed to take the care a reasonable person would take. This is the largest group.
No fault. The defendant is liable although he took all care. Examples are strict liability, absolute liability and statutory no-fault liability.

Motive is not the same as intention. Motive is the reason for acting. In most torts a bad motive does not make a lawful act wrongful. It does matter in a few torts, such as malicious prosecution, deceit and some forms of defamation.

Step 4: the two theories of liability

Fault theory. A person is liable only if he is at fault, meaning he acted intentionally or carelessly. This is the general rule.
No-fault theory. For some activities the law makes the person liable whatever his care. The reason is that he creates the risk and benefits from it.

Modern law uses both. Fault is the main basis, and no-fault liability fills the gaps where harm is great and proof of fault is hard.

Step 5: capacity and defences

A person who fits all the conditions may still escape. Capacity is covered in the note on parties to proceedings. General defences such as consent, necessity and private defence are covered in the note on general defences.

The bases of tortious liabilityHow to read this: start at the top and follow the lines. Green boxes are the three bases.

Liability in tort
- With fault
  - IntentionAssault, battery, false imprisonment, deceit.
  - NegligenceFailure to take reasonable care.
- Without fault
  - Strict and absolute liabilityRylands v. Fletcher, M.C. Mehta.
  - Statutory liabilityMotor Vehicles Act, section 164.
  - Vicarious liabilityEmployer for the employee's tort.

Don't confuse: the three bases of liability

Students often write "negligence" for every case. The table shows how the bases differ.

Point	Intention	Negligence	No fault
Mental element	Desired the result or knew it was almost certain	Failed to take reasonable care	None needed
Does care help the defendant?	No	Yes. Reasonable care defeats the claim	No. All care is not a defence (some limited defences exist)
Examples	Battery, false imprisonment, deceit	Careless driving, medical negligence	Gas leak from a hazardous plant, section 164 compensation

Inside intention. Varun slaps Mohan in a Hyderabad queue to humiliate him. He meant to touch him in a hostile way. This is battery.

Just outside it (no fault). A chemical factory takes every precaution but a pipe bursts and poisons nearby farmland. The factory never intended harm and was not careless, yet it is liable under the rule of absolute liability.

Common mistakes

Saying every tort needs intention. Negligence and no-fault torts do not.
Saying every tort needs fault. Strict, absolute and statutory liability do not.
Treating motive and intention as the same. Motive is the reason, and intention is the aim of the act.
Forgetting causation. A wrongful act and damage are not enough unless the act caused the damage.
Leaving out capacity and defences, which can end a claim even when the other conditions are met.

Apply it

Problem

A cyclist in Vijayawada is knocked down by a bus that a driver had left unlocked and unbraked on a slope. A boy released the brake while playing, and the bus rolled down and hit the cyclist. The cyclist sues the bus owner. Is the owner liable?

Issue. Is there a wrongful act, causation and fault when a third person's act was the direct cause?

Rule. Liability needs a wrongful act, legal damage, causation and, usually, fault. A new act of a third person can break the chain unless the defendant ought to have foreseen it.

Application. Leaving a bus unbraked and unlocked on a slope is careless. A child's tampering is a foreseeable risk, so it does not break the chain. The cyclist suffered legal damage.

Conclusion. The owner and driver are liable in negligence.

Leading case laws

Donoghue v. Stevenson (1932)
Facts. A snail was found in a ginger-beer bottle. The drinker had no contract with the manufacturer.

Principle. By 3 to 2, the House of Lords held that a manufacturer owes a duty of care to the consumer. Negligence became a general basis of liability.

Why it matters. It shows fault, in the form of carelessness, as the main basis.
Rylands v. Fletcher (1868)
Facts. A reservoir burst through old mine workings and flooded a neighbour's mine.

Principle. A person who keeps a dangerous thing on his land must keep it in at his own risk, whether or not he was careful.

Why it matters. It is the early authority for liability without fault.
M.C. Mehta v. Union of India (Oleum Gas Leak Case) (1987)
Facts. Oleum gas leaked from a factory in Delhi and killed a person.

Principle. The Supreme Court made hazardous industries absolutely liable for harm, with no exceptions.

Why it matters. It is the Indian authority for no-fault liability.
Overseas Tankship (UK) Ltd v. Morts Dock & Engineering Co. (The Wagon Mound No. 1) (1961)
Facts. Oil spilled into Sydney Harbour caught fire and damaged a dock.

Principle. The defendant is liable only for damage of a kind a reasonable person could foresee.

Why it matters. It fixes the legal side of causation.
Bradford Corporation v. Pickles (1895)
Facts. Pickles used his own land to cut off the water supply to a town's springs.

Principle. A lawful act does not become unlawful because of a bad motive.

Why it matters. It separates motive from the wrongful act.
