Undeterred by the adverse verdict by a US court on an appeal by Bhopal gas tragedy survivors, a group has taken up the fight against Union Carbide Corporation in the same court.

A case filed by Ramavtar Sahu for compensation, medical monitoring and clean-up of toxic waste near Union Carbide's plant in Bhopal as well as offsite water pollution is pending before the Court of Second Circuit of Appeals in USA.

"The Sahu matter has 12 plaintiffs alleging personal injury and health impacts from polluted water supply in Bhopal," their counsel H Rajan Sharma told PTI from New York.

The two cases were among the many cases filed by the survivors of the world's worst industrial disaster in Bhopal on the night of December 3, 1984, which killed more than 3,000 people and seriously affected more than two lakh others.

The US Court had earlier in August rejected the appeal of one Hasina Bi and 14 others for compensation and direction to Union Carbide to carry out clean-up operations in Bhopal. "It (Hasina Bi's case) was a significant setback, (but it is not the end of the matter," he said, adding Bi's case had certain limitations as it was only for property damage from Union Carbide India Ltd factory. Sharma said Sahu's case was different from the previous one and the verdict in Bi's case would not affect this case.

"The panel's opinion makes it clear that it was limited to the facts of Haseena Bi's case," he said and sought support from the government of India to help resolve the Sahu matter.
