Detailed Study Notes for Unit II

Unit-II: General Defences, Vicarious Liability, State Liability & Strict/Absolute Liability

1. General Defences to an Action in Tort

When a plaintiff files a suit for a tort committed against them, the defendant can escape liability by pleading and proving certain established general defences:

1. Volenti Non Fit Injuria (Consent):
   • Principle: To a willing person, injury is not done. If a person voluntarily consents to suffer harm or take the risk of injury (e.g., spectator at a cricket match or car race), they cannot sue for damages.
   • Exceptions / Limitations: Scienter (mere knowledge of risk) does not equal consent (voluntas). It does not apply in cases of rescue (Wagner v. International Railway Co.) or illegal acts.
2. Plaintiff the Wrongdoer (Ex turpi causa non oritur actio):
   • No action arises from a base cause. If the plaintiff’s own unlawful conduct is inextricably linked to the injury suffered, their claim may be barred.
3. Inevitable Accident:
   • An unexpected event that could not have been prevented or avoided by the exercise of reasonable care and precaution (Stanley v. Powell).
4. Act of God (Vis Major):
   • An extraordinary occurrence of natural forces (such as unprecedented storms, earthquakes, or extraordinary rainfall) entirely without human intervention, which could not have been foreseen or guarded against.
5. Private Defence:
   • Reasonable force used to protect one’s person, property, or family against unlawful aggression.
6. Statutory Authority:
   • An act authorized by a statute or legislative enactment does not constitute a tort (e.g., railway trains causing minor smoke or noise nuisance authorized by statute).
7. Necessity:
   • Harm caused intentionally to prevent a greater evil or public disaster (e.g., pulling down an adjacent house to stop the spread of a major fire).

2. Vicarious Liability (Liability for Wrongs Committed by Others)

• Meaning: Ordinarily, a person is liable only for their own wrongful acts. Under vicarious liability, one person is held legally liable for the tort committed by another due to a special relationship between them.
• Key Relationships:
  1. Master and Servant: An employer is liable for the torts committed by their employee committed during the course of employment (qui facit per alium facit per se).
  2. Principal and Agent: Principal is liable for torts of the agent acting within the scope of actual or apparent authority.
  3. Partners Inter Se: Partners are jointly and severally liable for torts committed by any partner in the ordinary course of the partnership business.

3. Liability of the State for Torts (Sovereign Immunity)

• Constitutional Position in India (Article 300): The Union of India and State Governments can sue and be sued, subject to the same liabilities that applied to the Dominion of India prior to the Constitution.
• The Doctrine of Sovereign Immunity: Historically, the state claimed immunity from tortious liability for acts done in the exercise of sovereign functions (e.g., maintenance of the armed forces, policing, or defense of the realm), while remaining liable for non-sovereign / commercial functions.
• Landmark Judicial Evolution: In State of Rajasthan v. Vidyawati, the Supreme Court held the state liable when a government jeep negligently ran over a pedestrian, ruling that driving a jeep is a non-sovereign function. However, in kasturi Lai v. State of UP, sovereign immunity was upheld when police stole gold seized from a jeweler. Modern constitutional jurisprudence has significantly eroded sovereign immunity in cases of gross violation of Fundamental Rights (awarding constitutional tort damages under Article 21/226).

4. Strict Liability and Absolute Liability

A. Rule of Strict Liability (Rylands v. Fletcher, 1868)

• The Rule: If a person brings, collects, or keeps upon their land anything that is likely to cause mischief if it escapes, they keep it at their peril and are prima facie answerable for all the damage which is the natural consequence of its escape, even in the absence of negligence or fault on their part.
• Exceptions to Strict Liability:
  1. Act of God.
  2. Act of a stranger (third-party intervention).
  3. Plaintiff’s own default or consent.
  4. Statutory authority.

B. Rule of Absolute Liability (M.C. Mehta v. Union of India, 1987)

• The Story & Legal Shift: Following the Oleum gas leak disaster in Delhi, the Supreme Court felt that the 19th-century exceptions under Rylands v. Fletcher were inadequate for modern industrial societies handling hazardous chemical processes.
• The Absolute Liability Rule: The Supreme Court laid down that an enterprise engaged in a hazardous or inherently dangerous industry which poses a potential threat to health and safety owes an absolute and non-delegable duty to the community. If any harm results due to the escape of hazardous substances, the enterprise is absolutely liable to compensate, and none of the exceptions under Rylands v. Fletcher (like Act of God or stranger’s act) can be pleaded as a defense. Furthermore, the quantum of damages must be proportional to the magnitude and financial capacity of the enterprise.

5. Extinction of Liability in Torts

Tort liability can be extinguished or discharged through several recognized legal modes:

1. Death of Parties (Actio personalis moritur cum persona): At common law, a personal right of action died with the person. In India, statutory enactments (Legal Representatives’ Suits Act and Indian Succession Act) allow survival of actions for property and financial damage.
2. Waiver and Acquiescence: Voluntary relinquishment of the right to sue.
3. Release: Formal discharge of liability by the injured party.
4. Accord and Satisfaction: Agreement to accept an alternative satisfaction in lieu of the original tort claim.
5. Law of Limitation: Failure to file a suit within the statutory limitation period extinguishes the legal remedy.

6. In-Depth Landmark Case Studies

Case Study 1: The Rule of Strict Liability (Escape of Dangerous Substance)

• Case Title: Rylands v. Fletcher
• Citation & Court: (1868) LR 3 HL 330 (House of Lords)
• Related Legal Principles: Strict liability, non-natural user of land, and escape of hazardous objects.
• The Story & Real-Life Background: The defendant mill owners constructed a water reservoir on their land. Due to the negligence of independent contractors who failed to block old, disused coal shafts beneath the reservoir, water burst through the shafts and flooded the plaintiff’s neighboring coal mines. The defendants argued they were not personally negligent since independent contractors caused the structural failure.
• Legal Issues Involved: Whether a landowner who brings a dangerous non-natural substance onto their land is strictly liable for damage caused if it escapes, regardless of personal absence of negligence.
• Final Judgement & Ratio Decidendi:
  • Ruling: The House of Lords held the defendants strictly liable, establishing that anyone who brings onto their land things that are dangerous and likely to do mischief if they escape must keep them at their peril, and is answerable for all natural damages upon escape.
  • Ratio: Non-natural use of land carrying inherent danger triggers strict liability upon escape.

Case Study 2: Absolute Liability for Hazardous Industries (Oleum Gas Leak Case)

• Case Title: M.C. Mehta v. Union of India
• Citation & Court: (1987) 1 SCC 395 (Supreme Court of India, Constitution Bench)
• Related Legal Principles: Absolute liability, hazardous industries, and non-delegable duty.
• The Story & Real-Life Background: Oleum gas leaked from a unit of Shriram Food and Chemical Industries in Delhi, resulting in the death of an advocate and widespread panic. Public interest litigation was filed seeking closure and heavy damages against the enterprise. The industry claimed the leak was caused by a sabotage / stranger’s act, which would normally serve as an exception under Rylands v. Fletcher.
• Legal Issues Involved: Whether Indian courts should adhere to English strict liability exceptions when dealing with modern hazardous chemical enterprises.
• Final Judgement & Ratio Decidendi:
  • Ruling: The Supreme Court formulated the stricter doctrine of Absolute Liability. The court held that an enterprise engaged in hazardous or inherently dangerous activities owes an absolute, non-delegable duty to ensure no harm occurs. No exceptions (such as Act of God or third-party acts) apply. Furthermore, damages awarded must be exemplary and tied to the financial capacity of the enterprise to act as a deterrent.
  • Ratio: Enterprises carrying on hazardous industrial activities assume absolute, non-escapable liability for any resulting harm.
