Defences Against Tortious Liability

Introduction

In the law of torts, a person is normally liable when their act causes harm or injury to another person. However, in certain situations the law recognizes that the act may be justified or excused.

Under such circumstances, the act will not be treated as wrongful, even though the same act would normally amount to a tort. These circumstances are known as defences against tortious liability.

Meaning / Definition

A defence in tort law is a legal ground or reason used by the defendant to avoid liability or reduce responsibility for the wrongful act.

In some cases, the law recognises that the act was done with valid justification or excuse. When such a defence is successfully proved, the defendant may completely escape liability or have the damages reduced.

Defences in tort law are generally divided into two main categories:

• General Defences
• Special Defences

Modes or Types

General Defences

General defences are those defences that do not depend on the nature of the tort. They are available in almost all types of tort cases.

These defences act as general exceptions to liability, meaning they limit the situations in which a person will be held responsible for a tort.

Common general defences include:

• Consent or Leave and Licence (Volenti non fit injuria)
  This means “a person who consents to harm cannot complain of injury.” If a person voluntarily agrees to take a risk, they cannot later sue for damages arising from that risk.

• Act of God
  This refers to natural events that are extraordinary and beyond human control, such as earthquakes, floods, or storms, where human foresight or care could not prevent the damage.

• Inevitable Accident
  An accident that could not have been avoided even with reasonable care and caution.

• Necessity
  An act done to prevent greater harm to persons or property may be justified under the defence of necessity.

• Private Defence
  A person is allowed to protect themselves, their property, or others from harm, provided the force used is reasonable.

• Acts Causing Slight Harm
  The law may ignore very minor harm (trivial harm) where the damage is too small to justify legal action.

• Statutory Authority
  If an act is authorized by a statute (law made by the legislature), it may not amount to a tort.

• Plaintiff the Wrongdoer
  This defence applies when the plaintiff himself was involved in wrongful conduct related to the claim.

• Judicial or Quasi-Judicial Acts
  Acts done by judges or authorities performing judicial functions (decision-making functions similar to courts) are generally protected.

• Parental and Quasi-Parental Acts
  Parents or persons acting in place of parents (such as teachers) may use reasonable control or discipline over children.

Special Defences

Special defences are those that apply only to specific torts. These defences depend on the nature of the particular tort involved.

For example:

• Truth is a defence available only in cases of defamation.
• Fair Comment is also a defence used in defamation cases, where the statement is an honest opinion about matters of public interest.

These defences cannot be applied to all torts, but only to the specific tort for which the law recognises them.

Distinction / Comparison

Practical Example

Suppose a person attends a cricket match as a spectator. While watching the match, the ball hits the spectator and causes injury.

Since the spectator voluntarily accepted the risks associated with the game, the defendant may rely on the defence of consent (volenti non fit injuria).

Thus, even though injury occurred, the defendant may not be held liable in tort.

Summary

• A defence in tort law is a legal reason used by the defendant to avoid or reduce liability.
• An act may be justified or excused under certain conditions, even if it would normally be a tort.
• Defences are broadly divided into general defences and special defences.
• General defences apply to all torts, such as consent, act of God, necessity, and private defence.
• Special defences apply only to certain torts, such as truth and fair comment in defamation.
• When a valid defence is proved, the defendant may escape liability or reduce the damages payable.
