The petitioner is accused of offence punishable under Section 138 of the Negotiable Instruments Act, 1881 (in short, the Act). It is contended by the petitioner’s counsel that the 1st respondent/ de facto complainant did not file promissory note said to have been executed by the accused in favour of the complainant to show existence of legally enforceable debt, even though execution of promissory note is alleged in the complaint. In a case under Section 138 of the said Act, promissory note is not the crucial document. The crucial documents on the basis of which the case stands, is the dishonoured cheque and the dishonoured memos. During the course of evidence, in case the complainant chooses to file it, he can do so after following the prescribed procedure. Failure to file promissory note along with the complaint is no ground to quash the complaint as such.
