Statutory Authority as a Defence to Torts
Statutory Authority as a Defence to Torts
What is Statutory Authority?
Statutory Authority refers to the legal power or authorization granted by a statute (law enacted by the legislature) to a person or entity to do something that would otherwise be a tort (wrongful act) if done without such authority.
Statutory Authority as a Defence
In tort law, statutory authority is a complete defence. This means:
If a person or authority does an act which causes harm or damage, but the act was done under the authority of a statute, then the person is not liable for the tort.
The reasoning is that the legislature has permitted the act, overriding the individual right to claim a tort.
Key Elements of Statutory Authority Defence
For statutory authority to be a valid defence, the following must be established:
Existence of a Statute: There must be a statute that authorizes the act.
Proper Exercise of Powers: The act must be done within the scope of the powers granted by the statute.
Compliance with Statutory Conditions: The person must comply with all conditions, safeguards, and procedures prescribed by the statute.
Act is not Ultra Vires: The act must not exceed the powers given by the statute.
No Malicious or Negligent Use: The authority must not use the powers in a malicious or negligent manner.
Scope and Limitations
The defence does not protect acts that are outside the scope of the statute.
Acts done maliciously or without reasonable care may still attract liability.
The statute must clearly or implicitly authorize the act causing the damage.
The defence generally applies to public authorities or persons acting under delegated statutory powers.
Examples of Acts Covered
Construction of roads or railways that damage adjacent properties.
Removal or demolition of structures under statutory orders.
Public health measures that interfere with private rights.
Acts done by government agencies under environmental or urban planning laws.
Leading Case Laws
1. Attorney General v. De Keyser’s Royal Hotel Ltd. (1920) (UK case but foundational)
The government entered and used the hotel during war without compensating the owners.
Held: Government was liable under statutory law because it used statutory powers without proper compensation.
Establishes that statutory authority must be exercised according to the statute’s provisions.
2. Adams v. Ursell (1913)
Local authority had statutory power to improve streets but caused damage to plaintiff's property.
Held: As the act was done under statutory authority and with care, no liability arose.
Demonstrates that acts done under lawful statutory authority are not tortious.
3. M.C. Mehta v. Union of India (1987) (Oleum Gas Leak Case)
Environmental pollution caused by statutory authority’s failure to act carefully.
Held: Statutory authority does not protect negligent or careless acts.
Shows limitation of the defence: statutory authority must be exercised with due care.
4. British Celanese Ltd. v. Hunt (1969)
Statutory authority was held to be a defence where the defendant’s acts were authorized by statute and were reasonable.
Acts beyond statutory limits or malicious acts are not protected.
5. Delhi Development Authority v. Skipper Construction Co. (1989) (Indian case)
Held that when a public authority exercises its statutory power within the limits prescribed by the statute, it is protected from tort liability.
However, if the authority acts negligently or beyond its powers, the defence does not apply.
Principles Summarized
| Principle | Explanation |
|---|---|
| Existence of Statutory Authority | The act must be authorized by a statute. |
| Scope of Authority | The act must be within the limits of statutory powers. |
| Compliance | All statutory conditions and procedures must be followed. |
| Reasonableness | The act must be done reasonably, without negligence or malice. |
| No Liability for Lawful Acts | No tort liability if done under lawful statutory authority. |
| Liability for Abuse or Negligence | If powers are abused or negligence occurs, defence fails. |
Practical Example
Suppose a municipal corporation demolishes an illegal structure as authorized under a local law. If the demolition causes damage to neighboring properties, the municipal corporation can invoke statutory authority as a defence, provided:
The demolition is authorized by the statute.
The corporation followed all legal procedures.
The act was not carried out negligently or maliciously.
If the corporation acted beyond its authority or carelessly, it can be held liable.
Conclusion
Statutory authority is a well-recognized defence in tort law protecting individuals or public bodies acting under lawful legislative powers from liability for acts that would otherwise be wrongful. It balances public interest and individual rights by recognizing the primacy of legislative authorization.
However, this defence is not absolute. It requires strict adherence to the law, reasonableness, and absence of malice or negligence.
