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.
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
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.
ICMR and clinic studies
Inquiry
Indian Council of Medical Research work and independent clinics document long-term illness in exposed populations.
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.
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.
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 identification88
MIC from the UCIL plant on 2–3 December 1984 is a stable fact.
Death-toll precision48
Immediate official, later government and campaign totals diverge by an order of magnitude if misread as one census.
Parent-company duty40
Civil closure in 1989 and failed extradition leave a thin criminal hold on UCC itself.
Site chemistry65
Contamination is documented; remedy responsibility is still argued.
Evidence closed the what. It did not produce a single satisfactory who-pays-the-rest.
