Section 304B is a substantive provision creating a new offence and not merely a provision effecting a change in procedure for trial of a pre-existing substantive offence. As a consequence, accused cannot be tried and punished for the offence of dowry death provided in section 304B of the Code with the minimum sentence of seven years’ imprisonment for an act done by them prior to creation of the new offence of dowry death;
