Understanding the Public Liability Insurance Act Post-Bhopal Tragedy

On the night of December 2-3, 1984, a catastrophic gas leak at the Union Carbide pesticide plant in Bhopal, India, exposed over half a million people to the deadly gas methyl isocyanate (MIC). Thousands died within days, and the long-term health consequences affected generations. The legal battles that followed dragged on for years, and many victims received inadequate compensation far too late. This tragedy exposed a critical gap in India’s legal system – there was no mechanism for providing swift relief to victims of industrial accidents. The Public Liability Insurance Act, 1991 (PLIA) was India’s legislative response to fill that gap.

The Bhopal disaster: why a new law was needed 🔗

The Bhopal gas tragedy remains one of the worst industrial disasters in recorded history. According to a review published in the journal Environmental Health, more than 40 tons of MIC leaked from the plant, killing at least 3,800 people immediately and causing severe long-term health effects for thousands more. Estimates of the total death toll vary widely – some sources place it between 15,000 and 20,000 over the following years.

The victims, most of whom lived in densely populated low-income neighbourhoods around the plant, suffered respiratory problems, blindness, reproductive issues, and neurological damage. Amnesty International has noted that the tragedy pushed already impoverished communities into further destitution, as many families lost their primary wage earners to death or disability.

The legal settlement between Union Carbide Corporation (UCC) and the Indian government, mediated by the Supreme Court in 1989, resulted in a payment of $470 million. This amount was widely criticised as grossly inadequate. Many victims received only a few hundred dollars, and the compensation process itself stretched over more than 15 years. The experience made it clear that existing laws could not deliver timely relief to accident victims – and that a new framework was needed.

Purpose and scope of the Public Liability Insurance Act, 1991 🔗

The PLIA was enacted on January 22, 1991, and came into force on April 1, 1991. Its stated objective is to provide for public liability insurance so that immediate relief can be given to people affected by accidents involving the handling of hazardous substances.

Key objectives of the Act 🔗

The Act was designed with three primary goals in mind. First, it mandates immediate financial relief to victims of industrial accidents, eliminating the need for them to endure years of litigation before receiving any compensation. Second, it imposes mandatory insurance obligations on all industries that handle hazardous substances, ensuring that funds are available when an accident occurs. Third, it introduces a no-fault liability framework – victims do not need to prove that the owner was negligent in order to claim relief.

Who does the Act apply to? 🔗

The Act applies to every “owner” associated with the production, storage, handling, or transportation of hazardous substances. Under the Act, “owner” is defined broadly – it includes not just the person who owns the facility, but also anyone who has control over the handling of hazardous materials at the time of an accident. In the case of a company, this extends to directors, managers, and officers who are directly responsible for the business operations.

The term “hazardous substance” refers to any substance or preparation classified as hazardous under the Environment (Protection) Act, 1986, provided it exceeds a quantity specified by the Central Government. The Act currently covers 179 chemicals and flammable substances.

What counts as an “accident”? 🔗

Under the PLIA, an “accident” is defined as any sudden and unexpected event involving hazardous substances that causes injury, death, or property damage. However, incidents caused by war or radioactivity are excluded from the Act’s scope.

Insurance requirements for hazardous industries 🔗

One of the most important provisions of the PLIA is the mandatory insurance requirement laid out in Section 4. Every owner handling hazardous substances must take out one or more insurance policies before commencing operations. These policies must cover the owner’s liability to provide relief in case of an accident.

How much insurance coverage is required? 🔗

The insurance policy must cover an amount that is not less than the paid-up capital of the business, subject to a maximum limit. As per the current provisions, the maximum coverage is ₹5 crore per accident and ₹15 crore per year. For owners who started handling hazardous substances before the Act came into force, a grace period of one year was provided to obtain the required insurance.

Penalties for non-compliance 🔗

The Act takes non-compliance seriously. Owners who fail to obtain the required insurance or violate any provisions of the Act face fines of up to ₹1 lakh and potential imprisonment of up to 7 years. This penal provision was designed to ensure that industries do not treat insurance coverage as optional.

The role of the M.C. Mehta judgment 🔗

The PLIA builds on the legal groundwork laid by the Supreme Court of India in the landmark case of M.C. Mehta v. Union of India (1987). In that case, which arose from an oleum gas leak at a Shriram Industries plant in Delhi in December 1985, the Court introduced the principle of absolute liability. This means that an enterprise engaged in a hazardous or inherently dangerous activity is absolutely liable for any harm caused, regardless of whether it exercised due diligence. The PLIA essentially codified this principle into a legislative framework with the added requirement of mandatory insurance.

Immediate relief for victims: the no-fault compensation mechanism 🔗

The most significant feature of the PLIA is its no-fault liability provision under Section 3. When an accident involving hazardous substances results in death, injury, or property damage to any person (other than a workman covered under the Workmen’s Compensation Act), the owner is liable to provide relief as specified in the Act’s Schedule – regardless of whether the owner was at fault.

How does a victim claim relief? 🔗

The process is designed to be straightforward. When the District Collector learns of an accident within their jurisdiction, they are required to verify its occurrence and publicise it so that affected people can file claims. Under Section 6 of the Act, victims or their legal representatives can submit a claim application to the Collector.

The Collector then conducts a summary inquiry, gives both the claimant and the owner an opportunity to be heard, and makes an award specifying the relief amount. Importantly, this process is intended to be completed within three months of receiving the application – a stark contrast to the years-long litigation that Bhopal victims endured.

Compensation amounts under the Schedule 🔗

The Act’s Schedule specifies the compensation amounts for different types of harm. For fatal accidents, a compensation of up to ₹25,000 is payable to the legal heirs of the deceased, in addition to reimbursement of medical expenses up to ₹12,500. For cases involving permanent total or partial disability, compensation is calculated based on the percentage of disablement as certified by an authorised physician. For property damage, an amount of up to ₹6,000 is payable based on actual damage incurred.

It is worth noting that these amounts represent immediate interim relief – not the final compensation. Victims retain the right to pursue further claims under other laws. Section 8 of the Act explicitly states that relief under the PLIA is in addition to any compensation a victim may claim under other legislation.

The Environmental Relief Fund 🔗

A key amendment introduced in 1992 added Section 7A, which empowers the Central Government to establish the Environmental Relief Fund (ERF). This fund serves as a financial safety net for situations where the relief amount awarded by the Collector exceeds what the insurance policy covers.

How is the ERF funded? 🔗

Every owner who takes out an insurance policy under the Act must also contribute an additional amount – equal to the insurance premium – to the ERF. The insurer collects this amount and remits it to the fund. The Environment Relief Fund Scheme, 2008, notified by the Ministry of Environment and Forests, appointed the United India Insurance Company Limited (UIICL) as the fund manager.

Current status of the ERF 🔗

By March 2023, the ERF had accumulated over ₹1,062 crore. However, reports indicate that a significant portion of this fund remains underutilised. This has raised concerns among environmental activists and legal experts, who argue that the fund should be more actively deployed for victim relief and environmental restoration. Under the National Green Tribunal (NGT) Act of 2010, compensation amounts ordered by the NGT for environmental damage can also be credited to the ERF.

Limitations and criticisms 🔗

While the PLIA was a landmark piece of legislation at the time of its enactment, it has faced considerable criticism over the years. The compensation amounts specified in the Schedule – ₹25,000 for death and ₹6,000 for property damage – were set in 1991 and have not been meaningfully updated to reflect current economic realities. Adjusted for inflation, these amounts offer very limited practical relief.

Enforcement remains inconsistent across states. The District Collectors, who serve as the primary enforcement authorities, often lack the resources or expertise to handle claims efficiently. Activists have pointed out that many accidents go unreported, and affected communities in remote or industrial areas may not even know about their rights under the Act.

Additionally, the Act only covers third-party victims – workmen are excluded from its scope and are instead covered under the Workmen’s Compensation Act. This exclusion has been debated, given that factory workers are often the first to be affected in chemical accidents.

Relevance of the Act today 🔗

Despite its shortcomings, the PLIA remains a significant part of India’s environmental and industrial safety framework. The 2020 gas leak at the LG Polymers plant in Visakhapatnam, which killed 12 people and affected thousands, brought renewed attention to the Act. Victims were entitled to compensation under the company’s public liability insurance policy, demonstrating that the Act’s mechanisms – however imperfect – still serve an important function.

As India continues to industrialise rapidly, the handling and storage of hazardous chemicals has expanded significantly. The PLIA’s core principle – that industries must be financially prepared to compensate victims before they even begin operations – remains relevant and necessary. However, periodic revision of compensation limits, stronger enforcement, and better awareness among communities living near hazardous industries are essential for the Act to fulfil its purpose effectively.

What do you think? Should the compensation amounts under the PLIA be linked to inflation so they stay meaningful over time? And how can communities near hazardous industries be better informed about their rights under this Act?
