The Supreme Court today dismissed CBI's curative petition against an earlier apex court judgement that diluted charges against the accused in the Bhopal gas tragedy case.A five-judge constitutional bench, headed by Chief Justice S H Kapadia, said the pending proceedings before the Sessions court against the Chief Judicial Magistrate's judgement awarding two years sentence to the accused, including Union Carbide India Chairman Keshub Mahindra will not be influenced by any order passed by it. The bench said that the CBI and the Madhya Pradesh government have failed to come out with a satisfactory explanation on filing the curative petition after a lapse of 14 years. The CBI and the Madhya Pradesh government had filed the curative petitions after a public outcry over what was considered as a mild punishment for a tragedy that claimed over 15,000 lives in December 1984 and had left several thousands maimed by the leakage of deadly Methyl Isocyanate gas.
