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.
