If a complainant makes four complaints to Police against the accused regarding cruelty for dowry demand while making several major and minor improvements regarding dowry demand in her successive complaints. The FIR gets registered on her final complaint in which complainant mentions her initial complaints as enclosures to her final complaint. During investigation and trial police doesn't take on record her first three complaints other than final complaint and first three complaints don't become part of the police challan u/s 173 CrPC. During her evidence complainant herself does not produce her initial three complaints while mentioning about them in her chief but identified her signature on her first & third complaint upon confronting.
My query is what is the legal effect/consequence of non-production of first three complaints by police in the final challan in court as well as by complainant during investigation and her chief ? Is there any provision of the evidence act or any case law which is applicable to this situation?
