2) false representation is one of the essential ingredients to institute the offence of cheating under Section 420 IPC. In order to bring a case for the offence of cheating, it is not merely satisfactory to prove that a false representation had been made, but it is further necessary to prove that the representation was false to the knowledge of the accused and was made in order to deceive the complainant.
