Concerned about the serious threat posed by huge toxic material left in Union Carbide’s Bhopal plant after the 1984 gas tragedy, the Supreme Court on Thursday summoned top officials of the Union and MP government to suggest measures for its early disposal.

A bench of Justices G.S. Singhvi and S.J. Mukhopadhyaya sought the presence of Union environment and chemical secretaries and Madhya Pradesh’s secretary for “Bhopal gas tragedy rehabilitation department” on Friday to give “assistance” to the court as how 350 tones of toxic waste deposited in Carbide plant should be disposed off as early as possible.
