Quick answers

What leaked at Bhopal?

Methyl isocyanate from a storage tank at the UCIL pesticide plant on the night of 2–3 December 1984. The page does not discuss how to handle or release the chemical. The public fact is an uncontrolled urban exposure.

How many people died?

The official immediate death toll often cited is 2,259. Indian government statements later used about 3,500 deaths in the first days and more than 15,000 gas-related deaths over the following years. Campaign estimates run higher. All of these are dated published figures, not a single census.

What was the 1989 settlement?

UCC paid US$470 million to the Union of India under Supreme Court orders of 14–15 February 1989 to resolve civil claims. Criminal proceedings were first quashed and later revived. Distribution of the money to claimants took years and remains criticised.

Who was convicted?

On 7 June 2010 a Bhopal court convicted seven former UCIL officials, including chairman Keshub Mahindra, and the Indian company of causing death by negligence (IPC 304A) and related counts. Sentences were two years and fines. An eighth accused had died. Warren Anderson was not in the dock.

Why is the status “mixed”?

Civil claims were settled; criminal law produced only negligence convictions of Indian employees; the American parent executive was never tried in India; the factory site’s contamination file is not closed. Those outcomes do not add to a single word like convicted or closed.

What Indian laws followed?

The 1985 claims-processing Act, the Environment (Protection) Act 1986 and the Public Liability Insurance Act 1991. Together they centralised claimant representation, environmental rule-making and no-fault industrial insurance.

Start with this section - Evidence

1984

The release is not in serious doubt. The strength of the file varies by question: chemistry, headcount, parent duty.

English discovery from the 1980s United States suits still feeds technical reconstructions.

Exhibits

Exhibit A

Plant logs and Tank 610

Document

UCIL operating records and later expert reports establish an MIC release from a named tank. Safeguard status is part of that paper.

Exhibit B

Municipal and health counts

Document

The 2,259 immediate official deaths and later five-figure attributions come from government statistical files, not from a single night register.

Exhibit C

ICMR and clinic studies

Inquiry

Indian Council of Medical Research work and independent clinics document long-term illness in exposed populations.

Exhibit D

1989 Supreme Court orders

Statute

The February 1989 settlement texts are the civil-law centre of the case and the reason mixed status is not the same as unsolved.

Exhibit E

1996 and 2010 criminal record

Testimony

The charge reduction and the June 2010 convictions fix what Indian criminal law was willing to hold Indian employees to.

Exhibit F

Site contamination studies

Physical

Soil and groundwater sampling after 1984 supports an unfinished cleanup file distinct from the gas-leak night.

How strong is the record?

Release identification
88

MIC from the UCIL plant on 2–3 December 1984 is a stable fact.

Death-toll precision
48

Immediate official, later government and campaign totals diverge by an order of magnitude if misread as one census.

Parent-company duty
40

Civil closure in 1989 and failed extradition leave a thin criminal hold on UCC itself.

Site chemistry
65

Contamination is documented; remedy responsibility is still argued.

Evidence closed the what. It did not produce a single satisfactory who-pays-the-rest.

Public-record encyclopedia. Not legal advice. Not a how-to. Graphic detail is withheld. Wars belong in a separate atlas.
