April 8, 1985: The Indian Government sues the Union Carbide Company in U.S. Federal Court in New York City, seeking damages from the December 1984 tragedy at Carbide's Bhopal, India factory.

The U.S. Court quickly dismisses the suit, but India pursues both legal and criminal action against the firm for years to come.
