A five-judge constitution bench of the Supreme Court will hear today the Centre's plea for prosecuting Bhopal gas tragedy case accused, who have escaped with lighter punishment of two years jail term, under the stringent penal provision attracting maximum ten years of imprisonment. The bench headed by the Chief Justice S H Kapadia will take up the curative petition seeking to recall the apex court's 14-year-old judgment that had diluted the charges against the accused who were prosecuted just for the offence of being negligent. The petition filed by CBI sought restoration of the stringent charge of culpable homicide not amounting to murder instead of death caused due to negligence against the accused in world's worst industrial disaster that left over 15,000 people dead and thousands maimed.
