A five-judge constitution bench of the Supreme Court will hear today the Centre's plea for prosecuting the Bhopal gas tragedy case accused, who have escaped with lighter punishment of two year jail term, under the stringent penal provision attracting a maximum of 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.
