Mitgistrate, but by the Court of Session without a committal within six months of the date of the offence on a complaint in writing by the Public Prosecutor with the previous sanction of the specified authorities. It is manifest that by the non-obstante clause, " notwithstanding anything contained in this Code" in sub-s. (1), the operation of diverse provisions of the Code relating to the initiation and trial of the offence of defamation is excluded and prime. facie s. 198 is one of those provisions. It is however urged on behalf of the appellants that sub.s.

(13) occurs clearly shows that the provisions of s. 198-B do not impair. the remedy provided by s. 198. It means that by s. 198-B the right which an aggrieved person has to file.a complaint before a Magistrate under s. 198 for the offence of defamation, even if the aggrieved person belongs to the specified classes and the defamation
