Factual Background
The Oleum gas leak occurred on 4th and 6th December 1985 at the Shriram industrial unit in Delhi, causing serious health hazards and one reported fatality. Given its proximity to the Bhopal disaster, the incident stirred public anxiety.
The Supreme Court, responding to the PIL, issued temporary closure orders and mandated safety protocols. The Court reviewed governmental and expert reports confirming the risk posed by hazardous industries in densely populated zones.
The outcome was the formulation of the absolute liability doctrine, which became a defining principle in Indian environmental law.
Abstract
This case significantly redefined environmental accountability in India. Triggered by a toxic gas leak in a crowded urban setting, the litigation established legal doctrines that ensured strict corporate responsibility. The absolute liability rule, introduced in the judgment, eliminated the need to prove negligence, making industries wholly responsible for environmental harm.
It also extended Article 21 to include environmental rights, enabling the judiciary to act more aggressively in protecting public health and natural resources. This judgment influenced not only legal reform but also set a new precedent for judicial activism in environmental matters.

Summary
The 1986 Supreme Court judgment in MC Mehta vs Union of India (AIR 1986 SC 1086) is a pivotal moment in India’s environmental legal landscape. It emerged from the Oleum gas leak at Delhi’s Shriram Food & Fertilizer Ltd., which sparked fears about industrial safety in urban areas shortly after the Bhopal Gas Tragedy.
Environmental advocate M.C. Mehta filed a Public Interest Litigation (PIL) under Article 32 of the Constitution, seeking accountability, compensation for victims, and preventive action. The Court introduced the doctrine of absolute liability, stating that enterprises handling hazardous materials are fully liable for any damage, regardless of negligence.

The judgment led to major regulatory reforms, improved industrial safety, and stronger environmental oversight, making it a cornerstone of India’s environmental governance.
