This discussion explores whether a complainant in a cheque bounce case (Section 138 NI Act) can call specific witnesses under Section 311 of the Criminal Procedure Code. The scenario involves a cheque issued by Krishnan that bounced due to insufficient funds, with Krishnan having previously received the money from his brother, Kannan. Experts generally agree that the complainant's mother can be called as a witness to support the case. However, calling Kannan as a witness is considered doubtful, as he is Krishnan's brother and might not provide favourable testimony, although he could potentially be named in the witness list.
