The scheme of the prosecution in punishing under Section 138 of the Negotiable Instruments Act is different from the scheme of Cr.P.C. Section 138 creates an offence and prescribes punishment. No procedure for the investigation of the offence is contemplated. The prosecution is initiated on the basis of a written complaint made by the payee of a cheque. Obviously such complaints must contain the factual allegations constituting each of the ingredients of the offence under Section 138. Those ingredients are (1) that a person drew a cheque on an account maintained by him with the banker; (2) that such a cheque when presented to the bank is returned by the bank unpaid; (3) that such a cheque was presented to the bank within a period of six months from the date it was drawn or within the period of it validity whichever is earlier; (4) that the payee demanded in writing from the drawer of the cheque, the payment of the amount of money due under the cheque to payee; and (5) such a notice of payment is made within a period of 30 days from the date of receipt of the information by the payee from the bank regarding the return of the cheque as unpaid. It is obvious from the scheme of Section 138 of the Act, that each one of the ingredients flows from a document which evidences the existence of such an ingredient. The only other ingredient which is required to be proved to establish the commission of an offence under section 138 is that inspite of the demand notice referred to above, the drawer of the cheque failed to make the payment within a period of 15 days from the date of the receipt of the demand. A fact which the complainant can only assert but not prove, the burden would essentially be on the drawer of the cheque to prove that he had in fact made the payment pursuant to the demand. N.
