“7.2. What is emerging from the material on record is that the issuance of a cheque by the accused and the signature of the accused on the said cheque are not disputed by the accused. The accused has also not disputed that there were transactions between the parties. Even as per the statement of the accused, which was recorded at the time of the framing of the charge, he has admitted that some amount was due and payable. However, it was the case on behalf of the accused that the cheque was given by way of security, and the same has been misused by the complainant. However, nothing is on record that in the reply to the statutory notice, it was the case on behalf of the accused that the cheque was given by way of security. Be that as it may, however, it is required to be noted that earlier the accused issued cheques which came to be dishonoured on the ground of “insufficient funds” and thereafter a fresh consolidated cheque of ₹9,55,574 was given which has been returned unpaid on the ground of “STOP PAYMENT”. Therefore, the cheque in question was issued for the second time. Therefore, once the accused has admitted the issuance of a cheque which bears his signature, there is a presumption that there exists a legally enforceable debt or liability under Section 139 of the NI Act. However, such a presumption is rebuttable in nature, and the accused is required to lead evidence to rebut such a presumption. The accused was required to lead evidence that the entire amount due and payable to the complainant was paid.
