A complainant has filed a single legal complaint under Section 138 of the Negotiable Instruments Act concerning 12 cheques that all bounced simultaneously. The accused had confirmed issuing these cheques and signed a mutual agreement. However, the Magistrate has deemed the complaint not maintainable, citing Sections 218, 219, and 220 of the CrPC, which generally relate to the trial of distinct offences. The complainant is seeking legal guidance and judgments to support the maintainability of a composite complaint in such circumstances.
