due dates and therefore, they extended the period by altering the dates in the Cheques and that was falsified by the evidence of PW.1 who admitted that the Cheques were discounted with the financiers and the appellant received money from the financiers, the amount mentioned in the Cheques and even though, it was stated that the appellant repaid the financiers the amount they received, there was no proof adduced by the appellant to that effect. Therefore, having regard to definition of Holder in due course, it cannot be stated that the appellant is the Holder in due course entitled to maintain action. He submitted that a perusal of the various cheques and the endorsements made thereon would prove that the Cheques were presented earlier for collection and the Cheques were endorsed in favour of the financiers and thereafter, the dates were altered and considering the material alteration, the Cheques became stale and invalid and also considering the fact that there were material alterations in the Cheques, the trial Court rightly dismissed the complaint. He also submitted that the statutory notice was not issued by the holder in due course and under proviso “b” of Section 138 of the N.I.Act, the payee or the holder in due course of the cheque, shall make a demand for the payment of the said amount of money by giving a notice in writing, to the drawer of the cheque, within thirty days of the receipt of information by him from the bank regarding the return of the cheque as unpaid. Admittedly, the statutory notice was issued by Murugan as Power agent of the appellant and no power document was produced and the said Murugan was not examined and in the absence of production of power, the notice issued by one Murugan who was neither a payee nor a holder in due course, was not a valid notice and on that ground also, the trial Court rightly dismissed the complaint. He therefore submitted that even assuming that the respondents were not able to rebut the presumption by giving evidence that they have not purchased yarn from the appellant and the Cheques were given as security, having regard to the admission of PW.1 that the Cheques were discounted with the financiers and the appellant received the money from the financiers, the appellant was not a holder in due course and the Cheques were materially altered by changing dates, the trial Court rightly dismissed the complaint, there is no need to interfere with the order of the trial Court.
