Facts
- Shriram Food and Fertiliser Industries operated units manufacturing hazardous chemicals in a densely populated part of Delhi.
- During the pendency of environmental proceedings concerning the safety of the plant, oleum gas escaped from the premises in December 1985.
- The leak caused the death of an advocate and injured several persons.
- Another leakage occurred shortly afterward.
- Claims for compensation were brought before the Supreme Court through a petition under Article 32.
- The enterprise argued that liability should be determined under the traditional rule in Rylands v. Fletcher.
- That rule imposed strict liability for escape of dangerous things but recognised several exceptions.
- The Court had to determine whether such nineteenth-century principles were adequate for modern hazardous industries.
Issue
- What standard of liability applies when a hazardous industry causes harm through an accident?
- Whether the enterprise could rely on exceptions available under Rylands v. Fletcher.
- Whether compensation could be pursued through proceedings under Article 32 for violation of the right to life.
Rule
- An enterprise engaged in a hazardous or inherently dangerous activity owes an absolute and non-delegable duty to the community.
- It must ensure that no harm results from the dangerous activity.
- If harm occurs, the enterprise is absolutely liable, irrespective of:
- negligence;
- reasonable care;
- act of a stranger;
- accident;
- other traditional exceptions.
- The enterprise is permitted to conduct the hazardous activity for its own profit and must therefore absorb the cost of resulting harm.
- The amount of compensation should be connected to:
- the magnitude of the harm; and
- the size and financial capacity of the enterprise.
Application
- The Court found the traditional English strict-liability rule inadequate for Indian conditions.
- Rylands v. Fletcher was developed in an era when industrial hazards were relatively limited.
- Modern chemical industries create risks capable of causing mass injury to workers, neighbouring residents and the environment.
- Such enterprises possess:
- technical knowledge;
- control over the dangerous process;
- financial capacity;
- ability to distribute accident costs through pricing and insurance.
- Members of the public ordinarily have neither knowledge of the risk nor any control over the activity.
- The Court therefore placed the entire accident risk upon the enterprise.
- It rejected a fault-based inquiry because requiring every victim to prove the precise negligent act would make compensation extremely difficult.
- The duty was described as non-delegable.
- Shriram could not avoid responsibility by arguing that:
- employees were at fault;
- safety systems had otherwise been maintained;
- an independent contractor was responsible;
- the accident was unexpected.
- The Court also linked hazardous-industry regulation to Article 21.
- Exposure of the public to lethal industrial danger directly affects life and personal security.
- Constitutional remedies must therefore be capable of responding effectively to mass environmental injury.
- Compensation was not to be treated merely as an ordinary private-law dispute between an individual claimant and a factory.
- It also served:
- a remedial purpose for victims;
- a deterrent purpose for industry;
- an incentive to maintain the highest safety standards.
- By relating compensation to the enterprise’s economic strength, the Court ensured that damages would not become an insignificant business expense.
- A larger and more prosperous enterprise would be expected to pay a correspondingly greater amount.
Conclusion
- The Supreme Court created the Indian doctrine of absolute liability for hazardous and inherently dangerous industries.
- The liability is stricter than the rule in Rylands v. Fletcher because no traditional exception is available.
- A hazardous enterprise must compensate every person harmed by its activity, even without proof of negligence.
- The Court also recognised the possibility of constitutional compensation where industrial harm violates Article 21.
- The case became the foundational authority for environmental and industrial liability in India.
- Later decisions applied this rule to toxic pollution, remediation and compensation claims.
- Use this case for: absolute and non-delegable liability of hazardous industries.
