Essential Elements of Tortious Liability for CLAT PGIntroduction
Tortious liability means holding someone legally responsible for a civil wrong, called a tort, that harms another person. A tort is an act or failure to act that causes injury, loss, or damage, like hurting someone, damaging property, or ruining a reputation. To prove tortious liability in court, certain essential elements must be shown. These elements apply to most torts, such as negligence, defamation, or trespass. For the CLAT PG exam, understanding these elements is important because questions often ask you to analyze cases or scenarios to check if liability exists. These notes explain the six essential elements—Wrongful Act or Omission, Duty of Care, Breach of Duty, Causation, Damage, and Mens Rea (for some torts)—in simple language with examples and key cases to help you prepare.
1. Wrongful Act or Omission
What Is It?
A wrongful act or omission is something the defendant does or fails to do that breaks a legal rule and harms the plaintiff. The act or omission must be something the law considers a tort, like hurting someone or neglecting a duty.
Why Is It Important?
For tortious liability, there must be an action or failure that violates the plaintiff’s rights or a duty owed to them. Without a wrongful act or omission, there is no tort.
Details
- A wrongful act is something active, like hitting someone, spreading lies, or driving recklessly.
- An omission is failing to do something required, like not fixing a dangerous staircase that causes someone to fall.
- The act or omission must be voluntary, meaning the defendant chose to do it or could have prevented it.
- It must be legally wrongful, meaning it breaks a legal duty or right, not just a moral rule. For example, being rude is not a tort, but damaging someone’s property is.
- The act or omission must lead to harm or affect a right protected by law.
Examples
- A person throws a stone and breaks a neighbor’s window. This is a wrongful act (trespass to property).
- A shop owner does not clean a slippery floor, and a customer falls. This is a wrongful omission (negligence).
- A newspaper publishes false news about someone, harming their reputation. This is a wrongful act (defamation).
Landmark Cases
- Donoghue v. Stevenson (1932):
- A woman drank ginger beer with a dead snail inside and got sick. The manufacturer did a wrongful act by not checking the product, causing harm.
- The court said this act was a tort because it violated the duty to make safe products.
- Ashby v. White (1703):
- An official stopped a man from voting, which was a wrongful act. Even though there was no physical harm, the act violated the man’s legal right to vote.
- The court said this was a tort because it affected a protected right.
2. Duty of Care
What Is It?
Duty of care means the defendant has a legal responsibility to act carefully to avoid harming the plaintiff. The law says some people must be cautious because their actions can affect others.

Why Is It Important?
Without a duty of care, the defendant is not responsible for the harm, even if they act carelessly. This element checks if the defendant was supposed to protect the plaintiff.
Details
- A duty of care exists when the defendant’s actions could reasonably harm someone close to them, like a driver to other road users or a doctor to a patient.
- The duty depends on foreseeability, meaning the defendant could predict their actions might cause harm.
- It also depends on proximity, meaning the plaintiff is someone directly affected by the defendant’s actions, like a customer buying a product.
- The most famous rule is the neighbor principle: You must avoid harming people who are so close to your actions that you should think about them.
- This element is key in negligence but also applies to torts like nuisance or harm from dangerous property.
Examples
- A car driver has a duty to drive safely to avoid hitting pedestrians.
- A company making food has a duty to ensure the food is safe for customers.
- A teacher has a duty to supervise students to prevent accidents.
Landmark Cases
- Donoghue v. Stevenson (1932):
- A woman got sick from a contaminated drink. The court said the manufacturer had a duty of care to customers, even without a contract.
- The neighbor principle was created: You owe a duty to people who could be harmed by your actions.
- Caparo Industries v. Dickman (1990):
- A company lost money relying on a faulty financial report. The court said there was no duty of care because the harm was not foreseeable, and the relationship was not close enough.
- The court made a three-part test: harm must be foreseeable, there must be proximity, and it must be fair to impose a duty.
3. Breach of Duty
What Is It?
Breach of duty happens when the defendant does not meet the expected standard of care. They act less carefully than a reasonable person would in the same situation.
Why Is It Important?
A breach shows that the defendant failed in their responsibility to protect the plaintiff. Without a breach, there is no tort, even if there was a duty.
Details
- The standard of care is what a reasonable person would do to avoid harm. For example, a reasonable driver follows traffic rules.
- The standard is objective, meaning it does not depend on what the defendant thinks but on what a typical person would do.
- For professionals, like doctors or engineers, the standard is higher. They must act as a reasonable professional in their field.
- To decide if there’s a breach, courts look at:
- How likely harm was.
- How serious the harm could be.
- How easy it was to prevent the harm.
- The plaintiff must show evidence that the defendant’s actions were below the standard.
Examples
- A driver speeds through a school zone and hits a child. This is a breach because a reasonable driver would slow down.
- A doctor ignores a patient’s symptoms, causing harm. This is a breach because a reasonable doctor would investigate.
- A store leaves broken glass on the floor, and a customer gets hurt. This is a breach because a reasonable store would clean it.
Landmark Cases
- Blyth v. Birmingham Waterworks Co. (1856):
- A water pipe burst and flooded a house because the company did not check it during a freeze. The court said there was no breach because a reasonable company could not predict the extreme cold.
- The court defined breach as doing something a reasonable person would not do or failing to do something they would.
- Bolam v. Friern Hospital Management Committee (1957):
- A patient was injured during a medical procedure. The court said there was no breach because the doctor followed a method accepted by some doctors.
- The Bolam test says a professional does not breach duty if they act in a way a responsible group of professionals would accept.
Question for Essential Elements of Tortious Liability
Try yourself:
What is required to establish tortious liability?Explanation
To establish tortious liability, there must be a wrongful act or omission. This means the defendant must have done something or failed to do something that breaks a legal rule and causes harm to the plaintiff. For example, if someone throws a stone and breaks a window, that is considered a wrongful act. Without this element, there is no tort.

4. Causation
What Is It?
Causation means the defendant’s wrongful act or breach caused the harm to the plaintiff. The harm must be a direct result of what the defendant did or failed to do.
Why Is It Important?
If the defendant’s actions did not cause the harm, they are not liable. Causation connects the breach to the plaintiff’s injury or loss.
Details
- Causation has two parts:
- Factual Causation: The harm would not have happened “but for” the defendant’s act or omission. This is called the but-for test.
- Legal Causation: The defendant’s act must be close enough to the harm, not too far or remote. The harm must also be a foreseeable result.
- Sometimes, there are multiple causes, like two people causing an accident. The defendant is liable if their act contributed significantly to the harm.
- An intervening act (something unexpected happening after the defendant’s act) can break causation. For example, if someone else’s action causes the harm, the defendant may not be liable.
- The harm must be a type that could be expected from the defendant’s actions.
Examples
- A driver runs a red light and hits a cyclist, breaking their leg. The breach (running the light) caused the harm (broken leg).
- A factory spills oil, but a fire starts because someone drops a match. The factory’s breach may not cause the fire if the match was unpredictable.
- A doctor gives the wrong medicine, and the patient gets worse. The doctor’s breach caused the harm.
Landmark Cases
- Barnett v. Chelsea & Kensington Hospital (1969):
- A man died from poison, but the hospital refused to treat him. The court said there was no causation because he would have died anyway, even with treatment.
- This shows the but-for test: the breach did not cause the harm.
- The Wagon Mound (No. 1) (1961):
- A ship spilled oil, and a fire later damaged a dock. The court said the fire was too remote because it was not a foreseeable result of the oil spill.
- This case says liability only covers harm that is a predictable result of the breach.
5. Damage or Harm
What Is It?
Damage or harm means the plaintiff suffered an injury, loss, or harm because of the defendant’s wrongful act. The harm must be something the law recognizes, like physical injury, financial loss, or emotional distress.
Why Is It Important?
For most torts, the plaintiff must show they were harmed to claim liability. Without damage, there is usually no tort, except in special cases.
Details
- Harm can be:
- Physical: Like a broken arm or illness.
- Economic: Like losing money or a job.
- Emotional: Like distress, but only in some torts.
- Reputational: Like harm from false statements.
- In negligence, the plaintiff must prove actual harm, like an injury or loss.
- Some torts, like trespass or libel, are actionable per se, meaning no harm is needed. Just violating the plaintiff’s right (e.g., entering their land) is enough.
- The harm must be significant, not minor or trivial, for the court to award compensation.
- The plaintiff must show the harm happened because of the defendant’s actions.
Examples
- A person slips on a wet floor in a store and breaks their ankle. The harm is the broken ankle.
- Someone spreads lies about a business, causing it to lose customers. The harm is financial loss.
- A person trespasses on private land but causes no damage. This is still a tort because trespass is actionable per se.
Landmark Cases
- Constantine v. Imperial Hotels Ltd. (1944):
- A man was refused a hotel room because of his race, violating his right. He suffered no real harm, so the court gave nominal damages (a small amount to show the right was violated).
- This shows some torts do not need actual harm.
- McGhee v. National Coal Board (1973):
- A worker got skin disease because his employer did not provide showers after working with dust. The court said the employer’s breach caused the harm by increasing the risk of disease.
- This shows that contributing to harm is enough for liability.
6. Mens Rea (in Some Torts)
What Is It?
Mens rea means the defendant had a guilty mind, like intending to harm or acting with malice. It is only needed for certain torts, like assault or defamation, not for all torts.
Why Is It Important?
For intentional torts, the defendant’s state of mind matters. Mens rea shows they meant to do the wrongful act or had a bad motive, making them liable.
Details
- Intention means the defendant wanted to do the act and cause the result. For example, hitting someone on purpose is intentional battery.
- Malice means acting with a bad motive, like spite or wanting to harm. It is important in torts like malicious prosecution or some defamation cases.
- In negligence, mens rea is not needed. Being careless is enough, even if the defendant did not mean to harm.
- For intentional torts, the plaintiff must prove the defendant acted deliberately or with a harmful motive.
- Mens rea is not needed for torts like nuisance or strict liability, where the focus is on the act or harm, not the defendant’s mind.
Examples
- A person punches someone to hurt them. This is battery with intention.
- A newspaper publishes a false story to ruin someone’s reputation. This is defamation with malice.
- A driver accidentally hits a pedestrian because they were not careful. This is negligence, and mens rea is not needed.
Landmark Cases
- Wilkinson v. Downton (1897):
- A woman was told a lie that her husband was hurt, causing her severe shock. The defendant meant to scare her, showing intention.
- The court said intentional harm, even without physical injury, is a tort.
- Bradford Corporation v. Pickles (1895):
- A man diverted water to harm a city’s supply, acting with malice. The court said malice did not matter because his act was legal.
- This shows mens rea is not always needed, depending on the tort.
